Detailed ways

In order to understand the features and technical contents of the embodiments of the present invention in more detail, the implementation of the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Under normal circumstances, when a terminal with CSFB function is turned on, it can search for the LTE network, complete the joint registration of the LTE/2G network, and can perform voice calling and calling.

The CSFB process includes three stages: 1) UE initiates a call on the LTE network (corresponding to MO), or receives a paging (corresponds to MT); 2) UE falls back under the guidance of the LTE network and searches for a suitable GSM cell/WCDMA cell for Access; 3) The UE reads the GSM cell/WCDMA cell system broadcast message and establishes a voice call.

With the continuous expansion of the scale of LTE base stations and the withdrawal and re-farming of some old GSM/TDSCDMA base stations, the configuration of the original network deployed on the signaling side of the base station is not updated in real time, and the configuration issued by the network to the UE appears. The information is inconsistent with the actual deployment situation, which leads to various abnormal situations in the inter-system (InterRAT) voice call of CSFB, such as failure to connect, repeated connection failure, etc.

In order to solve the call problems caused by the incompatibility of the network deployment, various terminal manufacturers have adopted various optimization methods to improve the call experience. Detection, in order to improve the CSFB optimization scheme in a targeted manner.

The CSFB fallback scheme adopts the 3GPP R8 redirection fallback scheme. During the CSFB deployment process, the CSFB process may be abnormal due to the problem of parameter configuration. To this end, an embodiment of the present invention provides a method for detecting a CSFB fallback result in a scenario where a terminal cannot initiate a CSFB process because a designated GSM cell is configured on the network side because two physical channels are configured for a common control channel.

Example 1

The embodiment of the present invention provides a method for detecting the fallback result of CSFB. FIG. 1 is a schematic flowchart of a method for detecting a fallback result of CSFB according to Embodiment 1 of the present invention; as shown in FIG. 1 , the method includes:

Step 101: In the process of initiating CSFB based on the indication information instructing the terminal to use the preset CSFB optimization scheme for voice service, it is detected whether the terminal accesses the first GSM cell within the preset time period.

In this embodiment, the terminal accessing the first GSM cell is triggered when the terminal fails to initiate the CSFB process based on the configuration information of the second GSM cell; the frequency point information of the second GSM cell is carried by the LTE base station and sent In the redirection command of the terminal; the configuration information includes configuring two physical channels to the common control channel; it can be understood that the adjacent cells configured by the terminal include the second GSM cell, that is, the adjacent cell configuration corresponding to the terminal. The information includes frequency point information of the second GSM, and the two physical channels of the second GSM cell in the neighbor cell configuration information are configured for a common control channel.

The indication information is carried in an attach accept message sent by the LTE base station to the terminal; the attach accept message is sent by the LTE base station after the terminal sends an attach request message to the LTE base station; the CSFB The process is triggered and executed when the terminal receives the paging message sent by the LTE base station.

In this embodiment, the frequency information of the neighboring cells included in the configuration information does not include the frequency information of the first GSM cell; and detecting whether the terminal accesses the first GSM cell within a preset time period includes: : Determine the frequency information of the first GSM cell based on the frequency scan initiated by the terminal, access the first GSM cell based on the frequency information of the first GSM cell within the preset time period, and detect the Whether the terminal accesses the first GSM cell within a preset time period.

As an implementation manner, when it is detected that the terminal accesses the first GSM cell, a reason parameter for requesting to access the first GSM cell is carried, and the reason parameter corresponds to the configuration information of the terminal based on the second GSM cell Failed to initiate CSFB process.

In practical application, a network environment applicable to this embodiment of the present invention can be constructed by means of laboratory simulation, that is, the scene where the terminal in the embodiment of the present invention is located is obtained by means of simulation. In this way, on the one hand, , the staff does not need to go to the site for testing, which can reduce the cost of personnel; on the other hand, the scene on the site may also contain other factors, which may affect the detection result, so the simulation network of the embodiment of the present invention can be used to stably reproduce the scene. The CSFB abnormal scenario that occurs in the network can eliminate the influence of other factors on the detection result in the scenario described in the embodiment of the present invention.

Based on this, in some embodiments, the voice call state of the terminal located in the simulated network environment under the GSM network is detected.

Step 102: Using the detection result, determine whether the CSFB has successfully fallen back.

In this embodiment, as a first implementation manner, using the detection result to determine whether the CSFB falls back successfully includes: when it is detected that the terminal accesses the first GSM cell within a preset time period, based on the The first GSM cell requests network resources to establish a voice call; when network resources corresponding to the first GSM cell are obtained and a voice call is established, it is determined that the CSFB fallback is successful.

Wherein, since the two physical channels of the second GSM cell are configured to the common control channel, it is detected that the terminal fails to initiate the CSFB process to the second GSM cell, thereby triggering frequency scanning to determine the frequency point information of the first GSM cell, based on the first GSM cell. The frequency point information of a GSM cell initiates access to the first GSM cell; when it is detected that the first GSM cell is accessed within a preset time period, the subsequent process of CSFB is performed, and it is detected that the first GSM cell is obtained corresponding to the first GSM cell. When the network resources are available and a voice call is established, it is determined that the CSFB fallback is successful.

As a second implementation manner, using the detection result to determine whether the CSFB falls back successfully includes: when it is detected that the terminal accesses a first GSM cell within a preset time period, based on the first GSM cell Requesting network resources to establish a voice call; when the network resources corresponding to the first GSM cell are not obtained or the voice call is not established based on the network resources of the first GSM cell, it is determined that the CSFB fallback fails.

Wherein, since the two physical channels of the second GSM cell are configured to the common control channel, it is detected that the terminal fails to initiate the CSFB process to the second GSM cell, thereby triggering frequency scanning to determine the frequency point information of the first GSM cell, based on the first GSM cell. The frequency point information of a GSM cell initiates access to the first GSM cell; when it is detected that the first GSM cell is accessed within a preset time period, the subsequent process of CSFB is performed, and it is detected that the first GSM cell has not been obtained. network resources, or when the voice call is not established, it is determined that the CSFB has failed to fall back. As another implementation manner, when it is detected that the voice call of the terminal in the first GSM cell is interrupted (not continued), it may also be determined that the CSFB fallback fails.

As a third implementation manner, using the detection result to determine whether the CSFB fallback is successful includes: when it is detected that the terminal does not access the first GSM cell within a preset time period, determining that the CSFB fallback fails .

Wherein, since the two physical channels of the second GSM cell are configured to the common control channel, it is detected that the terminal fails to initiate the CSFB process to the second GSM cell, thereby triggering frequency scanning to determine the frequency point information of the first GSM cell, based on the first GSM cell. The frequency point information of a GSM cell initiates access to the first GSM cell; when it is detected that the first GSM cell is not accessed within a preset time period, it may be determined that the CSFB fails to fall back.

In practical applications, when it is detected that the terminal fails to initiate the CSFB process to the second GSM cell, or when the terminal initiates access to the first GSM cell based on the frequency point information of the first GSM cell, a timer is started, and the timer is detected. Whether to access the first GSM cell before the timer expires. The timing duration of the timer may be set as required.

In this embodiment, whether the terminal accesses the first GSM cell within a preset time period can be detected through the relevant signaling configuration; correspondingly, whether the terminal is based on the first GSM cell can also be detected through the relevant signaling configuration. The network resources of the cell establish a voice call.

By adopting the technical solutions of the embodiments of the present invention, two physical channels can be configured to the common control channel in the configuration information of the neighboring cell (the second GSM cell) configured on the network side, so that the terminal can initiate the CSFB process based on the configuration information of the second GSM cell In the case of failure, the voice call state in the GSM network during the CSFB process is detected, so as to finally determine the fallback result of CSFB. In this way, in the subsequent process of CSFB, the optimization scheme can be further improved to improve the probability of the CSFB process being successful. In order to improve the user's calling experience.

Embodiment 2

In this application embodiment, a network environment is constructed through a simulation platform, including a Time Division Duplex (TDD)-LTE cell, a Time Division-Synchronous Code Division Multiple Access (TD-SCDMA, Time Division-Synchronous Code Division Multiple Access) cell, and a GSM cell; The GSM1 neighboring cell information is configured in the LTE SIB, the GSM 1 cell is configured as a neighboring cell, the LTE neighboring cell information is configured in the GSM SI, and CCCH-Config=2 is configured in the SIB3 of the GSM 1 cell, that is, two physical channels to CCCH.

The abnormal scenario of this application embodiment is: the GSM 1 cell configured by the network side reserves two physical channels for the CCCH, so that the terminal cannot initiate the CSFB process when performing CSFB to the GSM 1 cell. In this case, the terminal can use the GSM 0 cells that are not configured as neighbor cell information go through the CSFB process to verify the validity and rationality of the UE-side call optimization scheme.

The method for detecting the fallback result of CSFB in this application example, as shown in Figure 2, includes the following steps:

Step 200: The UE registers on the LTE cell and performs the attach procedure.

Specifically, when the UE is an MT, after the UE is powered on, it first executes an Evolved Packet System (EPS, Evolved Packet System)/International Mobile Subscriber Identification Number (IMSI, International Mobile Subscriber Identification Number) attach procedure.

Wherein, this process includes triggering the UE to send an Attach Request message (Attach Request) to the LTE base station, and receiving an Attach Accept message (Attach Accept) sent by the LTE base station, wherein the Attach Accept message carries instructions for indicating the terminal The instruction information of the voice service using the preset CSFB optimization scheme. 3 is a schematic diagram 1 of an emulation code according to an embodiment of the present invention, wherein: IMS voice over PS(V)=Not supported(0), which represents the indication information.

Step 201: the network side triggers the MT CSFB process, the network side sends a paging message (Paging) to the UE, and starts the CSFB process;

Here, in practical application, the MO needs to initiate a call to the MT first, and then the MT receives the paging message sent by the network side.

Specifically, after receiving the initial address request (IAM) incoming message, the mobile service switching center (MSC) in the network sends the SGsAP-PAGING-REQUEST message according to the existing SGs association and mobility management entity (MME, Mobility Management Entity) information To the MME, here, the SGsAP-PAGING-REQUEST message carries the following information: IMSI, Temporary Mobile Subscriber Identity (TMSI, Temporary Mobile Subscriber Identity), service indicator (Service indicator), calling number, and location area information.

After receiving the message, the MME sends a paging (Paging) message to the base station, and the base station initiates the Paging process of the air interface. The UE establishes a connection and sends the Extended Service Request message to the MME, the MME sends the SGsAP-SERVICE-REQUEST message to the MSC, and the MSC receives this message and does not resend the paging request message to the MME. In order to prevent the calling party from waiting too long during the call connection process, the MSC receives the SGs Service Request message including the idle state indication, and first informs the calling party that the call is in the connection process. The MME sends an Initial UE Context Setup message to the base station. Here, the Initial UE ContextSetup message carries the CS Fallback Indicator, which is used to instruct the base station UE to fall back to the UMTS Terrestrial Radio Access Network (UTRAN, UMTS Terrestrial Radio Access Network)/ GSM/EDGE Radio Access Network (GERAN, GSM EDGE Radio Access Network).

In the attach procedure, the UE receives the LTE_RRCConnectionRelease signaling, that is, the redirection command, sent by the LTE base station. The redirection command carries the frequency information of the GSM 1 cell. As shown in Figure 4, the base station issues an R8 redirection command (rrcConnectionRelease_R8(0)) to the UE, which carries the frequency information of the GSM 1 cell. Since two physical channels are reserved for the CCCH in the GSM 1 cell, this abnormality The scenario causes the terminal to fail to initiate the CSFB procedure when it executes the CSFB procedure to access the GSM 1 cell.

Step 202: The UE cannot initiate CSFB according to the specified frequency information, so it quickly performs frequency scanning to obtain the frequency information of the GSM 0 cell, and accesses the GSM 0 cell based on the frequency information of the GSM 0 cell within a preset time period , and request network resources to establish a voice call. If the GSM 0 cell is not accessed within the preset time period, it means that the CSFB fallback fails. Wherein, the access reason parameter is carried when requesting to access the GSM 0 cell, and the access reason parameter corresponds to the failure of the terminal to initiate the CSFB process based on the configuration information of the second GSM cell.

Step 203: Detect whether the UE obtains the network resources of the GSM 0 cell and establishes a voice call, if yes, execute step 204, otherwise, it indicates that the CSFB fallback fails, that is, the preset CSFB optimization scheme fails.

Step 204: Detect whether the UE maintains the voice call after the voice call is established. If yes, it means that the CSFB fallback is successful; otherwise, it means that the CSFB fallback fails, that is, the preset CSFB optimization scheme fails.
