Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

The core content of the present invention is: set the logic entity of unified management cluster user data, namely cluster service server (GTAdapter) is used for guaranteeing the home location register (HLR), group call register (GCR), subscriber identity module (SIM) data center data consistency. In addition, the trunking operation and maintenance terminal is further set up. The trunking operation and maintenance terminal can dynamically create a dynamic user group for trunking calls through the IE interface provided by the trunking service server. This group can be a voice group call service (VGCS) call and a voice broadcast service ( VBS) calls, if it is necessary to update or query the cluster user data, the cluster operation and maintenance terminal only needs to perform data management work such as adding, modifying, and deleting relevant data in the SIM card, HLR, and GCR through this logical entity. Moreover, the cluster service server can be set independently and implemented by a network device, or can be set as a module in an existing network device.

FIG. 1 is a schematic structural diagram of a system for realizing dynamic reorganization in the present invention.

Referring to Fig. 1, the system for implementing dynamic reorganization in the present invention includes: a cluster operation and maintenance terminal, a cluster service server, and a mobile communication system. The mobile communication system includes MSC/visitor location register (VLR), HLR, base station controller (BSS), mobile terminal (MS). A group call register (GCR) is set in each MSC to store group call information. Among them, the cluster operation and maintenance terminal is the management background of the cluster system, which can be directly connected with the cluster service server, or connected through a wireless access network (WAN); the cluster service server can be directly connected with MSC/VLR, HLR, or can be connected through a local area network , WAN, or other dedicated lines; MSC/VLR/GCR is connected to BSS. Here, the cluster service server and the cluster operation and maintenance terminal are new network elements, and the others are existing network structures.

In addition, the trunking service server stores the International Mobile Subscriber Identity (IMSI) and the subscriber telephone number (MSISDN), user priority, group call authority, corresponding group information, and group call area information of the group to which different users belong, Such as the cell list; in the HLR, IMSI and MSISDN identifying different users, priority information, group identification (ID) to which the user belongs, and other service information and status are stored. The services here include basic services and supplementary services; in GCR In the VLR, information such as the cell list where the group call occurs, group priority, etc. are stored; in the VLR, the group ID to which the user belongs, the user priority, and group call service subscription information are stored.

Referring to Fig. 2, based on the above-mentioned network structure, and the mobile communication system is a GSM system, the method for realizing dynamic reorganization is as follows:

Step 201: The trunking operation and maintenance terminal initiates a dynamic group creation request containing group information to the trunking service server. The group information includes at least group call reference, group call type, cell list, dispatcher list, and group call area, and may further include user numbers , number type, group call number, group call number type, etc.

Step 202: After receiving the request to create a dynamic group, the trunking service server determines the group call list, anchor MSC, anchor MSC group call area and relay MSC group call area of the group according to the group information, and sends a message to the anchor MSC Send a request to create a dynamic group, including group call reference and group call type and other group call reference and its attribute information; after receiving the request, the anchor MSC saves the group call reference and its attribute information in the corresponding GCR, and sends The cluster service server sends a group creation success response. The group call reference and group call type are used to uniquely identify a group call in the network, and the group call reference consists of a group ID and a group call area.

After receiving the request for creating a dynamic group, the trunking service server also generates any one of emergency call flag, encryption algorithm, key, group call channel length, group call channel type, and group call priority according to the group information in it. or several.

The anchor MSC is the home MSC of the user group, and the relay MSC is the roaming MSC of the user group. Here, the group call area of the anchor MSC and the relay MSC may be determined according to the information of the cell list in the user group information. For example, the MSC corresponding to the area where the cells are relatively concentrated is used as the anchor MSC, and the area where the cells are scattered is used as the relay MSC area. Certainly, the anchor MSC and relay MSC group call areas may also be determined according to user group information according to other principles.

Step 203: After the trunking service server receives the anchor MSC group creation success response, it determines whether there is a relay MSC according to the group call area in the user group information, and if so, the trunking service server initiates a dynamic group creation request to the relay MSC, After the relay MSC receives the request to create a dynamic group, it records the group call reference and group call type, the network element number information corresponding to the anchor MSC, and the group call area information of the relay MSC in its corresponding GCR, and the user group is created successfully. If it does not exist, the user group is considered to be created successfully.

At this point, a dynamic user group has been established, and then the user can add or delete group members or modify user information for the user group. Steps 214-223 are the process of adding group members.

Step 214: The cluster operation and maintenance terminal initiates a request for adding group members to the cluster service server, which contains the user number corresponding to the terminal to join the user group and the corresponding group ID information, and may further include the number type, etc. The group ID information Including group call number, group call number type, etc.

Step 215: After receiving the request for adding a group member, the trunking service server sends a request for adding a group member to the HLR, which contains the user number of the group member to be added and the corresponding group ID information.

Steps 216-218: After the HLR receives the request for adding group members, according to the subscriber number therein, it sends a USSD REQ message to the MSC/VLR at the user's location, notifying the MS to change the group ID information in the SIM card;

Steps 219-221: After receiving the USSD REQ message, the MS modifies the group ID information saved in the SIM card according to the group ID information therein, and returns a message of successful modification to the HLR.

Step 222: After the HLR receives the modification success message that MS returns, change the group ID information of this user's subscription in the corresponding home location database (HDB) of oneself, and notify the place VLR where the user roams to update the user group ID information, and the VLR will update the user group ID information according to The instruction of the HLR refreshes the user's group ID information in the VDB.

Step 223: The HLR returns to the trunking service server a message that the user has successfully added a group ID, after which members of the dynamic group can initiate and accept the group call.

Here, the cluster maintenance operation terminal can delete members in the group and add new members as needed; at the same time, the cluster maintenance operation terminal can also modify the cell range, dispatcher information, user priority information, etc. of the user group. When there is no group member in the user group, the cluster maintenance operation terminal can delete the user group.

When it is necessary to delete the group members of the user group, the implementation process is as follows: the cluster maintenance operation terminal sends a request to delete group members to the cluster service server, which at least carries the user number of the group member to be deleted and the corresponding group information; the cluster service server receives the request After the request of adding/deleting group members, initiate the request of deleting group members to HLR, which carries the user information and corresponding group information of group members to be deleted; The VLR and its connected BSS notify the MS to be deleted to change the group ID information saved by itself; then the MS modifies the group ID information saved by itself according to the notification, and sends a successful modification response to the HLR through the BSS and MSC/VLR; the HLR receives After the response message, change the corresponding group ID information saved by itself, and notify the MS roaming place VLR to update the user group ID information, and the VLR updates the corresponding group ID information saved by itself; finally the HLR can return the group ID deletion success message to the trunking service server.

The process of modifying the user group information by the cluster maintenance operation terminal is realized in this way: the cluster maintenance operation terminal sends a request for modifying user group information to the HLR through the cluster service server; the HLR determines the MSC where the user is located according to the user number, and notifies The MS modifies the group ID information; the MS modifies the group ID information saved by itself according to the notification, and sends a response message of successful modification to the HLR through the MSC; after receiving the response message, the HLR changes the corresponding group ID information saved by itself, and notifies the The VLR at the current location of the mobile terminal updates the user group ID information, and the VLR updates the corresponding group ID information saved by itself; the HLR returns a successful message of modifying the group information to the trunking service server.

In above-mentioned flow process, used USSD message, USSD message is existing message in the GSM system, is mainly used in transmission character string information, the present invention utilizes USSD message to notify user to update the dynamic group ID information in the SIM card. Define the content of the USSD application message used here as follows:

USSD string TAG: 04

USSD string Length:

USSD string: " ^* 149 ^* GroupId#"

Among them, 149 is a defined new service code identifier, which means that the string field information followed by it indicates that a group ID information is dynamically added or deleted by using this USSD message.

Referring to Table 1, the GroupId part includes the added or deleted group number, group type, group priority and addition/deletion/modification indication. Among them, the beginning of GroupId is 8 characters representing the group number to be added or deleted, followed by one-character group type information indicating whether the current group type is VGCS or VBS, followed by one-character group priority information, and the last If the character is added or deleted, it means adding or deleting the group, if it is modified, it means whether the priority of the corresponding user in the group has been modified, and whether the priority of the user in the group needs to be dynamically updated. Added or deleted group number group type group priority Add/Delete/Modify

Table 1

After the user has updated the SIM card group ID information, the user also uses the USSD message to return an update success message. The message structure is as follows:

USSD string TAG: 04

USSD string Length:

USSD string: " ^* 149 ^* Operate_result#"

Here, 149 is a defined new service code identifier, indicating that the terminal returns an update success message according to the update group ID information sent from the network side. The Operate_result part includes GroupId and operation result. Wherein, the operation result indicates whether the MS has successfully updated the group ID information in the SIM card, and if the update fails, different characters are used to indicate the reason for the update failure. Groupld operation result
