Background
In rail transit, the communication system of each line is often separately constructed, and a plurality of lines have a plurality of communication systems. At present, some new requirements arise in the operation of rail transit, for example: the train of the No. 2 line is adjusted to the No. 1 line for use; and for example, the head of the No. 1 line and the tail of the No. 2 line are combined into a new train to be used on the No. 1 line.
Due to the emergence of the new operating requirements mentioned above, there is also a demand for communication systems to establish groups across the system, for example:
1. it is necessary to dynamically reorganize a plurality of terminals or groups in two communication systems into a new group, which is a group across systems.
2. It is necessary to join a plurality of terminals or a plurality of groups in two communication systems into an existing group in one communication system through dynamic reorganization, and the group is formed into a cross-system group.
3. It is necessary to modify the properties of multiple terminals or groups in a group across the system.
4. It is necessary to delete a plurality of terminals or a plurality of groups from the group across the systems.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is further described in detail below with reference to the accompanying drawings and examples.
Fig. 1 is a schematic flow diagram of an embodiment of the method of the present invention, and as shown in fig. 1, the method for cross-system dynamic reconfiguration implemented in this embodiment mainly includes:
101, when a group home cluster control function body G-TCF receives a dynamic restructuring message of a corresponding group, triggering a home subscriber server eHSS _0 corresponding to the group home cluster control function body G-TCF and home subscriber servers eHSS _ i of other systems to respectively execute corresponding dynamic restructuring operations; the recombination indicated by the dynamic recombination message belongs to cross-system recombination; and the eHSS _ i is a home subscriber server which is indicated by the dynamic restructuring message and is not corresponding to a group member of the system to which the G-TCF belongs.
In this step, the group home cluster control function, i.e., G-TCF, of the group obtained by dynamic reorganization is used to trigger the home subscriber server of each system where the group members of the dynamic reorganization are located to execute the corresponding dynamic reorganization operation.
Here, the ehsf _ i is a home subscriber server indicated by the dynamic reconfiguration message and corresponding to a group member other than the system to which the G-TCF belongs, and in practical applications, the home subscriber server corresponding to a group member other than the system to which the G-TCF belongs may be a single home subscriber server or a plurality of home subscriber servers, and is specifically determined by the system in which the group member indicated by the dynamic reconfiguration message is located. The ehser _ i in this step will refer to each home subscriber server therein.
Preferably, the Dispatcher (DC) sending the dynamic reassembly message may exchange information with the G-TCF via its home cluster control function (H-TCF _ 1).
Correspondingly, the DC can send a dynamic reconfiguration message to the G-TCF through the H-TCF _1, specifically as follows:
step x1, the DC sends the dynamic restructuring message to the H-TCF _1.
Step x2, when the operation mode indicated by the dynamic restructuring message is to establish a new group, the H-TCF _1 judges that the H-TCF _1 is the G-TCF;
when the operation mode indicated by the dynamic restructuring message is to modify or delete an established group, the H-TCF _1 determines that the group affiliation trunking control function of the established group is the G-TCF, and forwards the dynamic restructuring message to the G-TCF when the group affiliation trunking control function is not the G-TCF.
In the sending method of the dynamic reconfiguration message, after receiving the dynamic reconfiguration message, the home trunking control function (H-TCF _ 1) of the DC determines, according to the operation mode indicated by the dynamic reconfiguration message and the group members participating in reconfiguration, the corresponding group home trunking control function (G-TCF) by the H-TCF _1, that is: when the operation mode indicated by the dynamic recombination message is to establish a new group, the DC home cluster control function body becomes the group home cluster control function body of the new group; and if the operation mode indicated by the dynamic reconfiguration message is to modify or delete the established group, the group home trunking control function of the established group is the group home trunking control function (G-TCF) of the reconfigured group, and at this time, if H-TCF _1 is not the G-TCF, then H-TCF _1 needs to forward the dynamic reconfiguration message to the G-TCF.
Preferably, the G-TCF may trigger the ehsf _0 to perform the corresponding dynamic reassembly operation by the following method:
the G-TCF sends a corresponding group information configuration request to the eHSS _0 according to the dynamic restructuring message;
and the eHSS _0 executes corresponding dynamic restructuring operation according to the group information configuration request, and feeds back the result of the dynamic restructuring operation to the G-TCF through a group information configuration response.
The specific execution method of the dynamic recombination operation in the above method is known to those skilled in the art, and is not described herein again.
Preferably, the G-TCF may trigger each ehsf _ i to perform a corresponding dynamic reassembly operation by using the following two methods:
the method comprises the following steps:
the G-TCF sends the dynamic recombination message to H-TCF _ i;
the H-TCF _ i sends a group information configuration request to a corresponding home subscriber server eHSS _ i according to the dynamic recombination message;
the eHSS _ i executes corresponding dynamic restructuring operation according to the group information configuration request, and feeds back the result of the dynamic restructuring operation to the H-TCF _ i through group information configuration response;
if the result of the dynamic restructuring operation carried by the group information configuration response indicates that the operation is successful, the H-TCF _ i stores corresponding group information and sends an SIP (200 OK) message to the G-TCF; otherwise, sending SIP (4 xx/5xx/6 xx) message to the G-TCF.
In the first method, the transfer of the dynamic reconfiguration information is performed based on the interfaces TC1 and TC2 between the two systems in the existing B-TrunC architecture (as shown in fig. 2).
The second method comprises the following steps: the method is realized on the basis of triggering the eHSS _0 to execute the corresponding dynamic restructuring operation, and specifically comprises the following steps:
after the G-TCF sends a corresponding group information configuration request to the eHSS _0 according to the dynamic restructuring message, the eHSS _0 sends a corresponding dynamic restructuring request to the eHSS _ i according to the group information configuration request;
the eHSS _ i executes corresponding dynamic restructuring operation according to the dynamic restructuring request, and feeds back the result of the dynamic restructuring operation to the eHSS _0 through dynamic restructuring response; sending a service data pushing Request ServiceData-Push-Request to the H-TCF _ i in the system to which the H-TCF _ i belongs; the service data pushing request carries group information after dynamic restructuring operation;
the eHSS _0 configures a response through the group information, and feeds back a result of the dynamic restructuring operation fed back by the eHSS _ i to the G-TCF; and the H-TCF _ i stores the group information carried in the request according to the service data pushing request, and feeds back a service data pushing response service data-Push-Answer to the eHSS _ i.
In the second method, the ehsp _0 directly triggers the ehsp _ i to perform the corresponding dynamic reassembly operation. Preferably, the ehsp _0 and the ehsp _ i can communicate with each other by using a newly added interface Tc5 (as shown in the system architecture of fig. 4).
Preferably, in order to improve the security and reliability of the interaction, the application layer protocol of the Tc5 may be a Diameter protocol, and the corresponding transport layer protocol may be an SCTP protocol. Or, the application layer protocol of the Tc5 is a SIP/RTP protocol, and the corresponding transport layer protocol is a UDP protocol.
And 102, the G-TCF judges whether the dynamic recombination is successful or not according to the result of executing the dynamic recombination operation by the eHSS _0 and the eHSS _ i and feeds back the result to a dispatching desk DC which sends the dynamic recombination message, triggers a group member indicated by the dynamic recombination message to update corresponding group information and register position information when judging that the dynamic recombination is successful, and feeds back the update and register results to the DC.
In this step, the G-TCF summarizes the execution results of all eHSS on the dynamic reassembly operation, decides whether the dynamic reassembly is successful, and feeds back the result to the DC.
It should be noted here that, in order to enable the relevant eHSS and TCF on the network side to store and maintain the user information of the group members after the dynamic reconfiguration, when the G-TCF determines that the dynamic reconfiguration is successful, the group members indicated by the dynamic reconfiguration message need to be triggered to update the corresponding group information and the registration location information.
Preferably, the G-TCF may determine whether the dynamic reconfiguration is successful according to a predetermined policy for determining whether the dynamic reconfiguration is successful. Those skilled in the art may set the judgment policy according to actual needs, for example, the following two judgment policies may be adopted:
the first strategy is as follows: and if the dynamic restructuring of at least one group member in the group members indicated by the dynamic restructuring message is successful, the G-TCF judges that the dynamic restructuring is successful.
And (2) strategy two: and if the dynamic restructuring of all the group members indicated by the dynamic restructuring message is successful, the G-TCF judges that the dynamic restructuring is successful.
Preferably, the G-TCF may trigger the group member indicated by the dynamic reconfiguration message to update the corresponding group information and the registration location information by using the following method:
the G-TCF triggers the group members in the system to update the corresponding group information and receives the group information update result fed back by the group members;
and the G-TCF triggers the group members in the non-affiliated system to update corresponding group information and report position information through the home trunking control function body H-TCF _ i of the group members in the non-affiliated system, and receives the group information update result and the position information fed back by the H-TCF _ i.
In the method, for the group members in the system where the non-G-TCF is located, the G-TCF needs to trigger the group members to update the group information and report the location information through the home trunking control function body H-TCF _ i of the group members, so that the group members can update the dynamically recombined group information of the cross-system group in time, and meanwhile, the G-TCF can acquire the location information of the group members, so that the G-TCF can maintain and manage the dynamically recombined cross-system group. The specific implementation of the update of the group information and the report of the location information in the above process is the same as that in the prior art, and is not described herein again.
It should be noted that: in the method, the position information needs to be reported for the group members in the system which is not the G-TCF, and for the group members in the system which is the G-TCF, because the group members and the G-TCF are in the same system, the system can grasp the position information of each terminal in real time, and therefore, the group members do not need to report and register the positions.
As can be seen from the foregoing method embodiments, in the foregoing embodiments, for mixed grouping across systems, the system manages group information and user information by using the following principle:
1. mixed grouping means that the member users in a group belong to two (or more) systems, and the group itself still has a definite home system.
2. The creation and management of the group is handled by the ehsf of the group home system, and the G-TCF of the group home system, the ehsf and TCF of other systems can all save and use the group information.
3. The user's creation and management is responsible for the eHSS of the user's home system, and the G-TCF of the user's home system, eHSS and TCF of other systems can store and use the user's information.
4. When the dispatching desk creates a new cross-system group, the default is that the group belongs to the system where the dispatching desk is located.
5. The dispatcher station can modify and delete a mixed grouping.
Based on the above principle, in the method and system for cross-system dynamic reconfiguration provided in the above embodiment, the group affiliation cluster control function G-TCF triggers the home subscriber servers of the systems where the group members of dynamic reconfiguration are located to perform corresponding dynamic reconfiguration operations, and summarizes the results of the dynamic reconfiguration operations of all the home subscriber servers, so as to determine whether this dynamic reconfiguration is successful and feed back the result to the corresponding scheduling console, and if it is determined that the dynamic reconfiguration is successful, the group members indicated by the dynamic reconfiguration message need to be triggered to update corresponding group information and registration location information, and feed back the result to the DC, so as to ensure that the home subscriber server and the cluster control function of each system involved can store and use information of corresponding group members for the mixed grouping obtained after reconfiguration. Therefore, the network side can be ensured to manage and maintain the cross-system mixed grouping, and the requirement of cross-system grouping is met.
The invention is further illustrated below with reference to the system architectures shown in fig. 2 and 4, respectively, by two specific implementation examples of the above-described method embodiments.
In the following two cross-system dynamic restructuring processes, the dynamically restructured group members relate to two systems, namely a system 1 and a system 2, where the system 1 is a system where the DC is located, and the home cluster control function (H-TCF _ 1) of the DC is the group home cluster control function (G-TCF) of the corresponding group. H-TCF2 is the TCF of System 2.
Fig. 3 is a flowchart of cross-system dynamic reconfiguration implemented based on the system architecture shown in fig. 2. In this flow, the dynamic reconfiguration information is transferred based on the two intersystem interfaces TC1 and TC 2. As shown in fig. 3, the process includes the following steps:
If a group is newly established and the operation type action in the message body takes the value create, the H-TCF1 takes the H-TCF as the group attribution G-TCF of the mixed grouping; .
If a group is modified, the operation type action in the message body takes the value modify, carries the group number GDN, and the H-TCF1 obtains the group attribution G-TCF through number analysis. It is assumed in this example that H-TCF1 is also the group home G-TCF for the cross-system grouping. Otherwise, the H-TCF1 needs to send a dynamic reassembly request SIP (MESSAGE) MESSAGE to the group-homed G-TCF, and further triggers a dynamic reassembly process between the group-homed G-TCF and the corresponding eHSS.
If a group is deleted, the dynamic recombination operation type action in the message body takes value delete, and carries the group number.
And step 2, the H-TCF1 sends a group information configuration Request (GroupInfo-Config-Request) message to the eHSS1 of the system where the H-TCF1 is located, and requests to perform dynamic recombination operation.
And step 3, the eHSS1 receives the GroupInfo-Config-Request message, carries out dynamic recombination operation, and returns the GroupInfo-Config-Answer message to the H-TCF1, and carries the operation result.
And step 4, the H-TCF1 sends a dynamic recombination (SIP MESSAGE) MESSAGE to the H-TCF 2.
And step 5, the H-TCF2 sends a GroupInfo-Config-Request message to the eHSS2 to Request for dynamic recombination operation.
And step 6, the eHSS2 receives the GroupInfo-Config-Request message, carries out dynamic recombination operation, and returns the GroupInfo-Config-Answer message to the H-TCF2, and carries the operation result.
Step 7, if the dynamic restructuring is successful, the H-TCF2 stores the group information in the dynamic restructuring message and sends an SIP (200 OK) message to the H-TCF 1; if the dynamic restructuring fails, the H-TCF2 sends a SIP (4 xx/5xx/6 xx) message to the H-TCF 1.
Step 8, the H-TCF1 judges whether the dynamic recombination is successful or not according to the dynamic recombination operation result fed back by the eHSS1 and the H-TCF2, if the dynamic recombination is successful, the H-TCF1 stores group information in the dynamic recombination message and sends an SIP (200 OK) message to the DC 1; if dynamic reassembly fails, H-TCF1 sends a SIP (4 xx/5xx/6 xx) message to DC 1.
And 9, triggering the group members in the system 1 to update the group information and reporting the update result by the H-TCF1 in the system 1 (the system where the H-TCF1 is located).
And step 10, the H-TCF1 triggers the group members in the system 2 to update the group information through the H-TCF2 in the system 2 (the system where the H-TCF1 is not located) and reports the update result and the position information.
And step 11, the H-TCF2 registers and reports the position information of the group members successfully updating the group information in the system 2 to the H-TCF 1.
Fig. 5 is a flowchart of cross-system dynamic reconfiguration implemented based on the system architecture shown in fig. 4. In the process, dynamic recombination information is transmitted based on the interfaces TC1 and TC2 between the two systems and the newly added interface TC 5.
As shown in fig. 5, the process includes the following steps:
If a group is newly established and the operation type action in the message body takes the value create, the H-TCF1 takes the group as the group attribution G-TCF of the mixed grouping; .
If a group is modified, the operation type action in the message body takes the value modify, carries the group number GDN, and the H-TCF1 obtains the group attribution G-TCF through number analysis. It is assumed in this example that H-TCF1 is also the group home G-TCF for the cross-system grouping. Otherwise, the H-TCF1 needs to send a dynamic restructuring request SIP (MESSAGE) MESSAGE to the group attribution G-TCF, and further triggers a dynamic restructuring process between the group attribution G-TCF and the corresponding eHSS.
If a group is deleted, the dynamic recombination operation type action value delete in the message body carries the group number.
And 2, the H-TCF1 sends a GroupInfo-Config-Request message to the eHSS1, the grouped group information is mixed, and dynamic recombination operation is requested.
And step 3, the eHSS1 sends a dynamic restructuring request message to the eHSS2, and the dynamic restructuring request message carries group information of mixed grouping.
And step 4, the eHSS2 sends a dynamic restructuring response message to the eHSS 1.
And step 5, the eHSS1 receives the GroupInfo-Config-Request message, performs dynamic restructuring operation, returns the GroupInfo-Config-Answer message to the H-TCF1, and carries the dynamic restructuring operation result of the eHSS2 and the eHSS.
Step 6, the H-TCF1 judges whether the dynamic recombination is successful or not according to the dynamic recombination operation results of the eHSS1 and the eHSS2, if the dynamic recombination is successful, the H-TCF1 stores group information in the dynamic recombination message and sends an SIP (200 OK) message to the DC 1; if dynamic reassembly fails, H-TCF1 sends a SIP (4 xx/5xx/6 xx) message to DC 1.
And 7, the eHSS2 sends a ServiceData-Push-Request message to the group H-TCF2, and pushes the group information of the dynamically recombined mixed grouping.
And step 8, the H-TCF2 stores the group information of the mixed grouping and returns a ServiceData-Push-Answer message to the eHSS.
And 9, triggering the group members in the system 1 to update the group information and reporting the update result by the H-TCF1 in the system 1 (the system where the H-TCF1 is located).
And step 10, the H-TCF1 triggers the group members in the system 2 to update the group information through the H-TCF2 in the system 2 (the system where the H-TCF1 is not located) and reports the update result and the position information.
And 11, the H-TCF2 registers and reports the position information of the group members successfully updating the group information in the system 2 to the H-TCF 1.
