Description

Automatic neighbor discovery method, device, communication equipment and storage medium

Technical Field

The present invention relates to the field of communications technologies, and in particular, to an automatic neighbor discovery method, an apparatus, a communication device, and a storage medium.

Background

The 5G Network introduces a Non-Public Network (NPN) or a Private Network (PRN), including an independent Non-Public Network (SNPN, stand-Alone NPN) and a Public Network integrated Non-Public Network (PNI-NPN, public Network INTEGRATED NPN), and enhances an automatic neighbor discovery function (ANR, automatic Neighbor Cell Relation Function) in R16 version, and the UE may report an NPN Identification (ID) of the new cell to the serving base station. The R17 version further enhances NPN characteristics and the cell also broadcasts a list of non-public networks (SO-SNPN, subscription Owner-SNPN) of whether each SNPN supports access using credentials of a third party entity and its supported Group Identity (GID), whether online subscriptions and their supported Group identity or subscription owner-independent networking. If the service base station wants to obtain the relevant information enhanced by NPN, an Xn interface with a new cell needs to be established, and the relevant information is interacted on the Xn interface, so that a certain time delay is brought. In addition, if the User Equipment (UE) needs to perform NPN enhanced service during the interaction, the serving base station cannot quickly learn which neighbor cell supports the service, and is likely to switch the UE to a neighbor cell that does not support the service, which causes interruption of the UE service.

The term "and/or" is merely an association relationship describing the associated object, and means that three relationships may exist, for example, a and/or B may mean that a exists alone, while a and B exist together, and B exists alone. In addition, the character "/" herein generally indicates that the front and rear associated objects are an "or" relationship.

The embodiment of the invention provides an automatic neighbor cell discovery method. Fig. 1 is a flow chart of an automatic neighbor discovery method according to an embodiment of the present invention, and as shown in fig. 1, the method includes:

Step 101, a terminal device sends first information to a first network device, wherein the first information comprises a non-public network identifier of a first cell, the first information also comprises whether the first cell supports online subscription and a supported group identifier or an SO-SNPN list, and/or whether the first cell supports access by using a third party entity and a supported group identifier;

In the conventional technical scheme, in the ANR process, the terminal equipment measures the signal of the cell and reports the measurement result to the first network equipment, wherein the reported measurement result can comprise the physical cell identifier (PCI, physical Cell Identifier) of the cell. If the first network device finds that the cell is the first cell, the first network device may instruct the terminal device to read an NR cell global identity (NCGI, NG-RAN Cell Global Identifier), a tracking Area identity (TAC, tracking Area Code), a radio access network Area identity (RANAC, RAN Area Code), a public land mobile network (PLMN ID, public Land Mobile Network) and an NR frequency point of the first cell, and report the NR cell global identity (NCGI, NG-RAN Cell Global Identifier), the radio access network Area identity (RANAC, RAN Area Code), and the NR frequency point to the first network device.

After the 5G network introduces the NPN or PRN, the terminal device may report, in addition to the above information, an NPN identifier (denoted as NPN ID) of the cell. But with corresponding enhancements to the NPN, the cell may also broadcast whether each supports online subscription (onboarding), and supported Group identity (Group ID) or SO-SNPN list (SO-SNPN list), and/or whether access using third party entities and supported Group identity (Group ID) is supported.

When the initial automatic neighbor cell is established, the terminal equipment reports the first information and/or the second information of the first cell. As an implementation manner, the terminal device may report to the network device whether the first cell supports online subscription and the supported group identifier or the SO-SNPN list, and/or the terminal device may report to the network device whether the first cell supports access using a third party entity and the supported group identifier. As another implementation manner, the terminal may also select to report the first information or the second information according to its own situation. After the first network device obtains the information of the neighboring cells, if the terminal which is carrying out online subscription and/or the third party entity access service is switched, the first network device can know whether the target cell supports online subscription and/or the third party entity access before the switching occurs, so that the terminal device is prevented from being switched to the cell which does not support the two services. In addition, the terminal reports the information, and the information is not required to be obtained through interaction with the Xn interface of the adjacent cell, so that the time delay is reduced, and the related signaling overhead on the Xn interface is saved.

The terminal device does not want to initiate the online subscription and/or the third party entity access service, or is not interested in the online subscription and/or the third party entity access service, which may specifically mean that the terminal device supports the online subscription function and/or supports the third party entity access function, but the terminal device may not currently want to initiate the online subscription and/or the third party entity access service for some reasons (such as a large resource occupation, a high energy consumption, etc.), or is not interested in the online subscription and/or the third party entity access service (uninterested), that is, the terminal does not initiate the online subscription and/or the third party entity access service in this case.

In some alternative embodiments, the method further comprises the terminal device obtaining the first information from the first cell.

Optionally, the terminal device obtains the first information from the first cell, and the method comprises the steps that the terminal device receives a broadcast message of the first cell, wherein the broadcast message comprises the first information, or the terminal device requests the first information from the first cell, and the terminal device receives the first information sent by the first cell.

In this embodiment, in one example, the terminal device may obtain the first information in a broadcast manner, that is, the first cell broadcasts the first information, and the terminal device receives a broadcast message of the first cell, thereby obtaining the first information. In another example, the terminal device may obtain the first information in an on-demand (on-demand) manner, i.e. the terminal device requests the first information from the first cell, and the first cell sends the first information to the terminal device after receiving the request.

In some optional embodiments of the invention, the method further comprises the terminal device receiving a first request message of the first network device, the first request message being used for requesting the terminal device to send the first information and/or the second information.

In this embodiment, the terminal device may send the first information and/or the second information to the first network device after receiving the first request message of the first network device.

In some alternative embodiments of the invention, the terminal device sending the first information to the first network device includes the terminal device sending the first information to the first network device when making or initiating an online subscription and/or accessing a non-public network using credentials of a third party entity.

In this embodiment, the terminal device may send the first information to the first network device under the condition that the terminal device itself satisfies a certain condition without being requested by the first network device. The sending of the first information to the first network device is illustratively triggered in case the terminal device makes or initiates an online subscription and/or uses credentials of the third party entity to access the non-public network (not limited here to before or after or during the service initiation procedure).

In some optional embodiments of the present invention, the method further includes, in a process of establishing a radio resource control connection between the terminal device and the first network device, the terminal device sending first indication information to the first network device, where the first indication information is used to indicate that the purpose of establishing the radio resource control connection is to perform online subscription and/or use a certificate of a third party entity to access a non-public network.

In this embodiment, in the process of establishing a radio resource control (RRC, radio Resource Control) connection with the first network device, the terminal device may instruct that the purpose of RRC access is online subscription and/or use a certificate of a third party entity to access a non-public network, and in this case, after receiving the first instruction information, the first network device may send a first request message to the terminal device, and may determine the content requested in the first request message.

Based on the above embodiment, the embodiment of the present invention further provides an automatic neighbor discovery method. Fig. 2 is a second flow chart of an automatic neighbor discovery method according to an embodiment of the invention, and as shown in fig. 2, the method includes:

Step 201, a first network device receives first information sent by a terminal device, wherein the first information comprises a non-public network identifier of a first cell, the first information also comprises whether the first cell supports online subscription and a supported group identifier or an SO-SNPN list, and/or whether the first cell supports access by using a third party entity and a supported group identifier;

And/or the first network device receives second information sent by the terminal device, where the second information includes a non-public network identifier of the first cell, and the second information is further used to indicate that the terminal device does not support online subscription and/or does not support access of a third party entity, or the second information is further used to indicate that the terminal device does not want to initiate online subscription and/or access of a third party entity, or is not interested in online subscription and/or access of a third party entity;

Step 202, the first network device updates a neighbor list based on the first information and/or the second information.

In this embodiment, the first network device may be a communication system or an access network device in a communication network, and by way of example, the first network device may be a base station, for example, a base station (gNB) of a 5G network.

When the initial automatic neighbor cell is established, the terminal equipment reports the first information and/or the second information of the first cell. After the first network device obtains the information of the neighboring cells, if the terminal which is carrying out online subscription and/or the third party entity access service is switched, the first network device can know whether the target cell supports online subscription and/or uses the third party entity access before the switching occurs, so that the terminal device is prevented from being switched to the cell which does not support the two services. In addition, the terminal reports the information without exchanging information with the Xn interface of the adjacent cell to obtain the information, so that the time delay can be reduced, and the related signaling overhead on the Xn interface is saved.

In some optional embodiments of the invention, the method further comprises the first network device sending a first request message to the terminal device, the first request message being used for requesting the terminal device to send the first information and/or the second information.

In some optional embodiments of the invention, the method further comprises the first network device obtaining capability information of the terminal device, determining whether to send the first request message to the terminal device or determining whether the first request message is used to request whether the first cell supports online subscription and supported group identity or SO-SNPN list, and/or whether the first cell supports access using a third party entity and supported group identity, based on the capability information.

In this embodiment, the first network device may obtain capability information of the terminal device, where the capability information of the terminal device includes whether the terminal device supports online subscription and/or whether the terminal device supports access using a third party entity. Furthermore, the first network device may determine whether to send the first request message to the terminal device based on the capability information of the terminal device, or may determine the content of the first request message according to the capability information of the terminal device, specifically, whether the first request message is used to request whether the first cell supports online subscription and a supported group identifier or SO-SNPN list, and/or whether the first cell supports access using a third party entity and a supported group identifier.

The first network device may obtain the capability information of the terminal device from the terminal device, or may also obtain the capability information of the terminal device from the core network device, for example.

In some optional embodiments of the present invention, the method further includes the first network device receiving first indication information sent by the terminal device, where the first indication information is used to indicate that the purpose of radio resource control connection establishment is online subscription and/or access to a non-public network using a certificate of a third party entity, and the first indication information is further used to determine whether the first request message is used to request the terminal device to send the first information and/or the second information.

In this embodiment, in the process of establishing the RRC connection with the first network device, the terminal device may instruct that the purpose of RRC access is online subscription and/or use a certificate of a third party entity to access to a non-public network, that is, the first network device receives first indication information sent by the terminal device, where in this case, after the first network device receives the first indication information, the first network device may determine, according to the first indication information, a content requested in the first request message, and may further send the first request message to the terminal device.

In some optional embodiments of the invention, the method further comprises the first network device receiving a first notification message of a second network device, sending a first request message to the terminal device based on the first notification message, the first notification message being used for notifying the first network device that the terminal device is updating a certificate for online subscription and/or updating a certificate for third party entity access, and the first notification message being further used for the first network device determining whether the first request message is used for requesting the terminal device to send the first information and/or the second information.

In this embodiment, in the process that the second network device updates the certificate for online subscription and/or updates the certificate for access of the third party entity for the terminal device, the second network device may also notify the first network device through the NG interface, so as to notify the first network device that the terminal device is updating the certificate for online subscription and/or updating the certificate for access of the third party entity. The first network device may send a first request message to the terminal device, and may determine, according to the first notification message, the content requested in the first request message, if the first network device knows that the terminal device may sign up online or use a third party entity to access.

Based on the above embodiment, the embodiment of the present invention further provides an automatic neighbor discovery method. Fig. 3 is a flow chart III of an automatic neighbor discovery method according to an embodiment of the invention, and as shown in fig. 3, the method includes:

Step 301, a second network device sends a first notification message to a first network device, where the first notification message is used to notify the first network device that a terminal device is updating a certificate for online subscription and/or updating a certificate for access of a third party entity, and the first notification message is further used by the first network device to determine whether a first request message sent to the terminal device is used to request the terminal device to send first information and/or second information;

The first information comprises a non-public network identifier of a first cell, the first information further comprises a group identifier or SO-SNPN list which is supported by the first cell and whether the first cell supports online subscription and supported by the first cell, and/or whether the first cell supports access by a third party entity and supported by the first cell, the second information comprises a non-public network identifier of the first cell, the second information is further used for indicating that the terminal equipment does not support online subscription and/or does not support access by the third party entity, or the second information is further used for indicating that the terminal equipment does not want to initiate online subscription service and/or access by the third party entity, or is not interested in online subscription and/or access by the third party entity.

In this embodiment, the second network device is a core network device.

In embodiments of the present invention, the first Cell may also be referred to as a New Cell (New Cell), and may specifically be a Cell that is reported by the terminal device and is not in the neighbor list. The terminal device may report the measurement result to the first network device (e.g., the base station), where the reported measurement result includes the PCI of the cell, the first network device retrieves the neighbor list, determines that the PCI of the cell is not in the neighbor list, and then the first network device may request the terminal to obtain the global cell identifier (CGI, cell Global Identity) and other information of the cell, so as to identify the cell, and then the cell may be referred to as a new cell or a target cell in the automatic neighbor discovery process.

The automatic neighbor discovery method according to the embodiment of the present invention is described below with reference to specific examples. In the following examples, the UE represents the terminal device, the 5G radio access network (NG-RAN) represents the first network device, and the Core Network (CN) represents the second network device, and in the following examples, the new cells are the first cells in the above embodiments.

Example one

In this example, when the CN updates the credentials (credentials) for online subscription (onboarding) to the UE and/or is updating the credentials (credentials) for third party entity access, the CN informs the NG-RAN via the NG interface, the NG-RAN knows that the UE may be online subscription or use the credentials of the third party entity to access a non-public network, the NG-RAN configures the UE to report the NPN ID of the new cell (if any), if the NPN ID of the new cell is SNPN ID, whether the new cell supports online subscription (onboarding), and supported Group identification (Group ID) or SO-SNPN list (SO-SNPN list), and/or whether the new cell supports use of third party entity access and supported Group identification (Group ID).

Fig. 4a is a schematic interaction flow diagram of an automatic neighbor discovery method according to an embodiment of the present invention, and as shown in fig. 4a, the method includes:

step 400 the cn updates the UE with the certificate (credentials) for the online subscription (onboarding).

Here, the CN updates the UE with the certificate (credentials) for the online subscription (onboarding) through the NG-RAN, which transparently passes the message, which does not know the content of the message.

Step 401 the CN sends a first notification message to the NG-RAN, i.e. the CN notifies the NG-RAN that the UE is updating the certificate for the online subscription (onboarding) (credentials).

Step 402, the UE reports the PCI information of the new cell.

It should be noted that the order of the step 402 and the step 401 is not limited to the above, and the step 402 may also precede the step 401.

Step 403, the ng-RAN sends a first request message to the UE to request the UE to report the NPN ID of the new cell (if any), and if the NPN ID is SNPN ID, to report whether SNPN of the new cell supports online subscription (onboarding) and its supported Group ID or SO-SNPN list.

Step 404, the UE acquires first information from the new cell, wherein the first information comprises a non-public network identification of the new cell, and the first information also comprises whether the new cell supports online subscription and a supported group identification or SO-SNPN list.

In this embodiment, the UE may read the broadcast system information of the new cell to obtain the first information, or obtain the first information in an on-demand manner.

Step 405, the ue reports first information to the NG-RAN, that is, reports information about the new cell, including an NPN ID of the new cell, and may further include whether SNPN supports online subscription (onboarding) and a Group ID or SO-SNPN list supported by the online subscription if the NPN ID is SNPN ID.

Here, if the new cell does not have SNPN information, the UE will not report the relevant NPN information.

Step 406 ng-RAN updates the neighbor list.

Here, the NG-RAN adds the related information of the new cell to the neighbor relation of the own cell, and stores the above information received from the UE, and updates the neighbor list.

As shown in fig. 4b, the difference from fig. 4a is that fig. 4b is an example for access by a third party entity, comprising:

the CN updates the UE with the certificate for the third party entity access (credentials), step 500.

Step 501, the cn sends a first notification message to the NG-RAN, the first notification message notifying the NG-RAN that the UE is updating the credentials for the third party entity access (credentials).

Step 502, the ue reports PCI information of the new cell.

It should be noted that the order of the steps 502 and 501 is not limited to the above, and the step 502 may also precede the step 501.

Step 503, the ng-RAN sends a first request message to the UE, where the first request message requests the UE to report the NPN ID of the new cell (if any), and if the NPN ID is SNPN ID, it requests whether SNPN of the new cell supports access using the third party entity and the Group ID supported by the same.

Step 504 the ue obtains first information from the new cell, the first information comprising an NPN ID of the new cell (if any) and, if the NPN ID is SNPN ID, whether SNPN of the new cell supports access using third party entities and supported group identities.

Step 505, the ue reports first information to the NG-RAN, that is, reports information about the new cell, including an NPN ID of the new cell, and may further include whether SNPN supports access using a third party entity and a supported group identifier if the NPN ID is SNPN ID.

Step 506 ng-RAN updates the neighbor list.

Here, the NG-RAN adds the new cell to the neighbor relation of the own cell, and stores the above information received from the UE, and updates the neighbor list.

For example, the neighbor list may be shown in table 1, where "the group identifier supporting online subscription or the SO-SNPN list" and "the group identifier supporting access of the third party entity" are defined separately, and the UE reports separately.

TABLE 1

In this example, if the Group ID is broadcast in a SIB other than the system information block (SIB, system Information Block) 1, if the reported information includes the association or mapping between the Group ID and SNPN, the UE also needs to report the association or mapping between the Group ID and SNPN to the NG-RAN.

Example two

In this example, when the UE performs online subscription (onboarding) or accesses using the certificate (credentials) of the third party entity, the UE actively reports the NPN ID of the new cell (if any), and if the NPN ID of the new cell is SNPN ID, it also reports information such as whether SNPN of the new cell supports online subscription (onboarding) and the Group ID or SO-SNPN list supported by the new cell, and/or whether the new cell supports access through the third party entity and the Group ID supported by the new cell. Or if the UE indicates that its access is for online subscription (onboarding) or that its access is using a certificate of a third party entity (credentials) during RRC connection establishment, after receiving the indication, the NG-RAN may request the UE to report whether SNPN of the new cell supports online subscription (onboarding) and its supported Group ID or SO-SNPN list, and/or whether SNPN of the new cell supports access using a third party entity and its supported Group ID.

Fig. 5a is a second schematic interaction flow chart of an automatic neighbor discovery method according to an embodiment of the present invention, where, as shown in fig. 5a, the method includes:

step 601, the UE sends first indication information in the RRC connection establishment procedure to indicate that the purpose of the RRC connection establishment is for online subscription (onboarding) or that the UE is using certificate (credentials) access of a third party entity.

Step 602, the UE reports PCI information of the new cell.

Step 603, after receiving the first indication information of the UE, the ng-RAN may send a first request message to the UE to request the UE to report information of the new cell, where the information includes reporting an NPN ID of the new cell (if any), and request whether SNPN of the new cell supports online subscription (onboarding) and a Group ID or SO-SNPN list supported by the new cell if the NPN ID is SNPN ID.

This step is an optional step.

Step 604, the ue obtains first information from the new cell, wherein the first information includes an NPN ID of the new cell (if any), and if the NPN ID is SNPN ID, the first information further includes whether the new cell supports online subscription, and a supported group identity or SO-SNPN list.

In step 605, the ue reports first information to the NG-RAN, that is, reports information about the new cell, including an NPN ID of the new cell, and may further include whether SNPN supports online subscription (onboarding) and a Group ID or SO-SNPN list supported by the online subscription if the NPN ID is SNPN ID.

Optionally, if step 603 is not included in this example, the ue may actively report the related information of the new cell, including the NPN ID of the new cell, and may further include whether SNPN supports online subscription (onboarding) and the Group ID or SO-SNPN list supported by the online subscription if the NPN ID is SNPN ID.

Step 606 ng-RAN updates the neighbor list.

Here, similarly to the example one, the NG-RAN adds the related information of the new cell to the neighbor relation of the own cell, and saves the above information received from the UE, updating the neighbor list.

As shown in fig. 5b, the difference from fig. 5a is that fig. 5b is an example for access by a third party entity, comprising:

Step 701, the ue sends first indication information in the RRC connection establishment procedure to indicate that the purpose of the RRC connection establishment is to use credentials (credentials) of the third party entity for access.

Step 702, the ue reports PCI information of the new cell.

Step 703, after receiving the first indication information of the UE, the ng-RAN may send a first request message to the UE to request the UE to report information of the new cell, where the information includes reporting an NPN ID of the new cell (if any), and request whether SNPN of the new cell supports access using a third party entity and a Group ID supported by the NPN ID if the NPN ID is SNPN ID.

Step 704, the ue obtains first information from the new cell, the first information including an NPN ID of the new cell (if any), and if the NPN ID is SNPN ID, the first information further includes whether SNPN of the new cell supports access using a third party entity and a supported group identity.

Step 705, the ue reports first information to the NG-RAN, that is, reports information about the new cell, including an NPN ID of the new cell, and may further include whether SNPN supports access using a third party entity and supported group identification if the NPN ID is SNPN ID.

Step 706 ng-RAN updates the neighbor list.

Example three

In this example, the NG-RAN configures the UE to need to report the NPN ID of the new cell (if any), if the NPN ID of the new cell is SNPN ID, it also reports whether the new cell supports online subscription (onboarding), and supported Group identity (Group ID) or SO-SNPN list (SO-SNPN list), and/or whether the new cell supports access using third party entities and supported Group identity (Group ID). If the UE does not support third party entity access or does not support online subscription (onboarding) or does not currently want to initiate at least one of the above services, it may choose not to report corresponding information, and may indicate to the NG-RAN itself that the function is not supported or that the service is not desired to be initiated or that the service is not of interest.

Fig. 6 is a schematic diagram of an interaction flow chart of an automatic neighbor discovery method according to an embodiment of the present invention, where, as shown in fig. 6, the method includes:

step 801, the ue reports PCI information of the new cell.

Step 802, ng-RAN sends a first request message to UE to request UE to report NPN ID of new cell (if any), and if NPN ID is SNPN ID, report SNPN of new cell whether online subscription (onboarding) and Group ID or SO-SNPN list supported by the new cell, and/or report SNPN of new cell whether access using third party entity and Group ID supported by the new cell are supported.

Step 803 the ue obtains first information from the new cell, the first information comprising a non-public network identity of the new cell (if any), in case the NPN ID is SNPN ID, the first information further comprising whether the new cell supports online subscription and a supported group identity or SO-SNPN list, and/or the first information further comprising whether SNPN of the new cell supports access using third party entities and a supported group identity.

Step 804, if the UE does not support the online subscription (onboarding) and/or the third party entity access, or the UE is not interested in any service, the UE may report second information to the NG-RAN, that is, not report related information of the new cell, where the second information may include an NPN ID of the new cell, and the second information may further indicate that the UE does not support the online subscription and/or the UE does not support the third party entity access function, or the second information is further used to indicate that the UE does not want to initiate the online subscription service and/or the third party entity access service, or the UE is not interested in the online subscription service and/or the third party entity access service.

Step 805 ng-RAN updates the neighbor list.

Here, the NG-RAN record SNPN may be used to obtain corresponding information from other UEs, whether the NG-RAN record SNPN supports an online subscription (onboarding) function and/or whether access using a third party entity is supported. For example, the neighbor list may be as shown in table 2, where "the group identifier supporting online subscription or the SO-SNPN list" and "the group identifier supporting access of the third party entity" are defined separately, and the UE reports separately.

TABLE 2

Example four

In this example, the NG-RAN decides whether to configure the UE to report the related information of the new cell according to the capability of the UE (i.e. whether the UE supports the online subscription (onboarding) function or whether to support the access of the third party entity), i.e. the NG-RAN decides whether to send the first request information to the UE according to the capability of the UE, determines the content of the first request message according to the capability of the UE, whether to request whether the new cell supports the online subscription and the supported group identifier or SO-SNPN list, and/or whether the new cell supports the access using the third party entity and the supported group identifier. If the UE does not support the online subscription (onboarding) functionality and does not support the third party entity access functionality, the NG-RAN may not send the first request message to the UE. If the UE supports only the online subscription (onboarding) function or only the third party entity access function, the NG-RAN may send a first request message to the UE, where the first request message is only used to request whether the new cell supports online subscription and supported group identity or SO-SNPN list, or is only used to request whether the new cell supports access using the third party entity and supported group identity.
