Description

Group area adjustment method and system, cluster application server and cluster user terminal

technical field

The present invention relates to the communication field, and in particular to a group area adjustment method and system, a cluster application server and a cluster user terminal.

Background technique

The trunking mobile communication system is a dedicated business dispatching system. Multiple users (departments, groups) in the system share a set of radio channels and use these channels dynamically. It is mainly used for command dispatching communication. The trunking communication system has the characteristics of sharing resources, sharing costs, sharing channel equipment and services, multi-purpose, and high performance. The service application of the trunking mobile communication system requires the service provider to set a service scope for the trunking user according to the service type, and the service scope is called a group area. The group area is generally defined as a list of several cells. When a group service is initiated, the system will send a group service notification to all cells based on the list of cells in the group area to create a shared channel to initiate the group service.

In actual cluster business applications, due to different industry characteristics, the areas where cluster user groups are located are relatively fixed and dynamically changing. For example, railway cluster users are located in narrow and long track coverage areas most of the time. Their work area and business scope are relatively fixed. Another example is firefighting group users, because the firefighting operation area is constantly changing, so their work area and business area will change dynamically. In the prior art, the group area corresponding to the cluster user (terminal) is relatively fixed, and the resources configured for the group area are also relatively fixed; when the position of the cluster user terminal corresponding to the cluster user changes, such as leaving its original registered group When the cluster user is not connected to the corresponding network, cluster services may not be performed normally; or when the cluster user no longer accesses the corresponding network, network resources will be wasted. Therefore, a method for adjusting the group area is needed, which can dynamically adjust the group area corresponding to the cluster user according to the identification information such as the location information and status information of the cluster user terminal corresponding to the cluster user, and at the same time adjust the core network corresponding to the cluster user; When a cluster user roams to an area other than the group area or leaves the group area, the cluster user can still access the corresponding network, perform cluster services normally, and improve network resource utilization at the same time.

detailed description

Embodiments of the present invention will be further described in detail below through specific implementation methods in conjunction with the accompanying drawings.

Embodiment one:

With the continuous development of communication technology and the continuous increase of user needs, group communication/trunk communication has gradually changed from traditional private network applications to public network applications. In this context, 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project ) based on the LTE (Long Term Evolvement, long-term evolution technology) technology, a GCSE (Group Communication System Enabler, Group Communication Service Engine), a standard framework for group communication/cluster communication is proposed. Figure 1 is a system diagram of the GCSE framework, which mainly includes GCSE AS (GCSE Application Server, group communication application server), GCSE Application (group communication application), EPC (Evolved Packet Core, evolved packet core network) and E-UTRAN (Evolved-Universal Terrestrial Radio AccessNetwork, evolved UMTS Terrestrial Radio Access Network) and MuSe (Multipoint Server) five parts. Among them, GCSE AS is the central unit of group communication/cluster communication, which is used to complete business transaction processing such as cluster user management, group area management, and group business processing; GCSE Application is the agent unit of cluster users, residing in UE (User Equipment, user device) application layer, which cooperates with GCSE AS to complete the login and logout of cluster users and the transmission and reception of cluster related information; E-UTRAN is the wireless part of the LTE network, which mainly completes the allocation of wireless resources and the access of mobile users , which includes eNB (Evolved Node B, evolved base station); EPC is the core network part of LTE, which mainly completes the bearer establishment and maintenance of different types of user services, and mainly includes MME (Mobility Management Entity, mobile management entity), PGW ( PDNGateway, public data network gateway), SGW (Serving Gateway, service gateway), etc. The GCSEApplication introduced in the GCSE architecture interacts with the GCSE AS through the C/S mode, realizing the separation of business applications and bearer networks, enabling services to make full use of the high bandwidth, low latency, and all-IP advantages of LTE technology to provide users with High-quality, diverse, and large-capacity cluster service experience, and this interactive mode also makes user management and maintenance more flexible and efficient.

This embodiment proposes a group area adjustment method based on the above-mentioned GCSE system and the fact that the cluster user group in the cluster communication is relatively fixed and dynamically changing, as shown in FIG. 2 , specifically including:

Step S201, setting a preset group area for the cluster user; the preset group area includes a cell information list preset for the cluster user.

Specifically, setting preset group areas for cluster users means that during cluster service planning, authorized users can pre-set preset group areas in GCSE AS according to different industries or departments corresponding to the cluster users, such as setting fire protection The system preset group area, the public security system preset group area, etc., in the actual application, the preset group area corresponds to at least one cluster user terminal, and the cluster user terminal is the terminal that the cluster user logs in or stores the identity of the cluster user terminal. In addition, the preset group area can be understood as a pre-set cell information list for the cluster user terminal, that is, for example, if the cluster user terminal is a terminal corresponding to the fire protection system, then the fire system group area may include the group where the cluster user terminal is often located A cell information list, the cell information list has at least one.

Further, setting a preset group area for the cluster user terminal includes: setting a static group area corresponding to the cluster user, the static group area includes at least one cell information list; selecting at least one cell information list from the static group area as the cluster user corresponding Preset group area.

Specifically, when setting the preset group area, a static group area can be set first, that is, a static group area can be preset by considering information such as the frequent location of the cluster user corresponding to the cluster user terminal, and the location area to which the cluster user may roam. , the static group area includes at least one list of cell information corresponding to the cluster user; then part or all of the static group area can be selected as the preset group area of the cluster user according to needs, for example, considering the cluster user's usual location The location may be relatively stable, so only select the cell information list of the area that they are usually in as the preset group area. At this time, the preset group area can be used as the in-operation group area when performing trunking services. The setting of the static group area can be specifically set by authorized users with setting authority. In addition, after the preset group area is selected, the remaining cell information list can be used as a reserve cell information list library for use in the subsequent adjustment of the preset group area. The setting of the static group area can be flexibly set according to actual needs, so as to meet the requirements of relatively stable and relatively changing scenarios of the cluster user terminals in the cluster user group.

Further, when setting a static group area, the business of the static group area can be limited in the form of kilometers, latitude and longitude, administrative area, office area, or cells in the LTE network, and then the GCSE AS The format is the same as a cell in the LTE network, and a corresponding cell information list is generated.

In addition, after setting the preset group area, it also includes setting the EPC core network corresponding to the cluster user terminal according to the preset group area, specifically sending the set preset group area to the MME server, and the MME The server stores the preset group area to the HSS (Home Subscriber Server, Home Subscriber Server) server for subsequent service in the cluster user terminal, so that the EPC core network can identify the cluster user terminal according to the preset group area stored in the HSS. The cluster business is processed accordingly.

Step S202, acquiring identification information of cluster user terminals.

Specifically, in order to ensure that the cluster user terminals in the GCSE system can normally perform cluster services, or dynamically allocate system resources in the system, the status information of the cluster user terminals in the system can be monitored by obtaining the identification information of the cluster user terminals Wait. Acquiring the identification information of the cluster user terminal specifically includes: receiving identification information actively reported by the cluster user terminal; or sending an acquisition instruction to the cluster user terminal to obtain the identification information of the cluster user terminal. That is, when a cluster user terminal logs in or logs out of its corresponding GCSE Application, or when the location of the cluster user terminal changes, it actively sends its identification information to the GCSE AS, so that the GCSE AS can use the identification information to correspond to the cluster user terminal. The preset group area is adjusted; the change of the position of the cluster user terminal can specifically refer to that the cluster user in the connected state performs cell handover; or the cluster user in the idle state performs TAU (Tracking Area Update, tracking area update), or in the Cluster users in the idle state perform TAC (Tracking Area Code, tracking area reselection) and so on. When the cluster user terminal sends the identification information to the GCSE AS, specifically, the cluster user terminal may send the identification information to the MME, and then the MME forwards the identification information to the GCSE AS. Of course, the GCSE AS may also send an acquisition request to the cluster user terminal in real time or periodically to obtain the identification information of the cluster user terminal, so as to adjust the preset group area corresponding to the cluster user terminal according to the identification information. Wherein, the identification information may specifically include the identity information of the cluster user terminal, such as the group number, the preset group area to which it belongs, etc., location information or login status information, etc., and the location information may be the latitude and longitude information of the current location of the cluster user terminal, or It may also be the information of the cell where the cluster user terminal is currently located.

Step S203, adjusting the preset group area corresponding to the cluster user terminal according to the identification information.

Specifically, after the identification information of the cluster user terminal is obtained, the identification information may be analyzed to first parse out the identity information of the cluster user terminal, and then search for a corresponding preset group area according to the identity information. After the corresponding preset group area is found, it is judged whether the adjustment of the preset group area satisfies the adjustment condition, and the preset group area meeting the adjustment condition is adjusted. The adjustment conditions may include adjustment and processing user permissions, resource constraints, etc., that is, the identity information can be matched with the adjustment and processing user permissions. If the identity information is not within the scope of adjustment and processing user permissions, it means that the GCSE AS cannot directly The preset group area corresponding to the cluster user terminal is adjusted. At this time, the authorized user may be notified, and the authorized user decides whether to allow the adjustment of the preset group area. When the identity information is within the scope of the adjustment processing user authority, the GCSE AS can directly adjust the preset group area. In addition, it is also possible to pre-calculate the change of the system resources after the adjustment of the preset group area, and decide whether to adjust the preset group area according to the change of the system resource. If the business is busy, if the preset group area is adjusted at this time, the resource occupation of the adjustment process may have too much impact on the network, so you can decide not to adjust the preset group area; if the impact is not large, you can Preset group area adjustments. In addition, the adjustment condition may also include an adjustment processing priority, and when the group area adjustment process is relatively busy, the preset group area corresponding to the cluster user terminal with a higher priority is preferentially adjusted. Of course, it is also possible to first determine whether the cluster user terminal corresponding to the preset group area has the authority to trigger group area adjustment. Make adjustments.

Further, adjusting the preset group area corresponding to the cluster user terminal according to the identification information includes: adding the cell information list corresponding to the cluster user terminal to the preset group area according to the identification information; Delete the cell information list corresponding to the cluster user terminal.

Specifically, the user login status information used to determine the adjustment type is parsed from the identification information. If the user login status information is that the cluster user has logged in to the GCSE Application or the cluster user has logged in to the GCSE Application and is online, the adjustment can be determined. The state may be a new adjustment operation; wherein, when in the online state, the cluster user terminal may specifically be in a state such as cell handover or tracking area change. Then, according to the current location information parsed from the identification information, it is matched with the cell information list in the preset group area. If there is a cell information list corresponding to the current location information in the preset group area, the preset group area will not be identified. Adjustment; if there is no cell information list corresponding to the current location information in the preset group area, it is necessary to adjust the preset group area, that is, to add the cell information list corresponding to the current location information to the preset group area; The cell information list corresponding to the current location information can be generated according to the current location information, or the cell information list in the current location information can be directly added to the corresponding preset group area; it can also be selected from the static group area As part of the preliminary cell information list library, the cell information list corresponding to the current location information is selected and added to the preset group area. Further, if the location of the cluster user terminal changes, the corresponding cell information list before the location change can also be found in the preset group area according to the identity information in the identification information. At this time, according to the actual situation, Deciding whether to delete the original cell information list corresponding to the cluster user terminal from the preset group area; when there is no cluster user terminal corresponding to the preset group area in the cell corresponding to the original corresponding cell information list, you can Delete the original corresponding cell information list from the preset group area. If the user login status information is that the cluster user exits the GCSE Application, it can be determined that the adjustment status is a delete adjustment operation, that is, the corresponding cell information list is searched in the preset group area according to the location area parsed from the identification information, if If found, the preset group area is adjusted, and the cell information list corresponding to the location information is deleted. It should be understood that the deletion of the cell information list above may also refer to marking the cell information list corresponding to the location information as "invalid", even though it may still be in the preset group area, it is not given when performing trunking services. The cell marked as "invalid" sends the cluster service information corresponding to the preset group area, and it is in the "deleted" state for the GCSE AS when the service is carried. The adjusted preset group area is still a list library composed of several cell information lists.

Specifically, referring to FIG. 3 , the authorized user sets a static group area, wherein the cell information list in the static group area sequentially includes cell information list 1, cell information list 2, ..., cell information list x, ..., cell information list n, select cell information list 1, cell information list 2, ..., cell information list x as the preset group area. If it is necessary to add the cell information list corresponding to the location information of the cluster user terminal to the preset group area, it may first be determined whether the part of the static group area that does not belong to the preset group area contains the cell information corresponding to the location information list, if it exists, directly select the cell information list from the static group area, and add the cell information list to the preset group area; if the cell information list corresponding to the position information of the cluster user terminal is "cell information list n ", you can add the "cell information list n" to the preset group area, and if the original cell information list corresponding to the cluster user terminal is "cell information list x", you can also add the "cell information list x" at this time x" is removed from the preset group area. The adjusted preset group area is shown in Figure 4.

Further, in the static group area, as a reserve cell information list library, it can also be provided to the authorized user to directly add the part that does not belong to the preset group area to the preset group area, for example, when encountering an emergency call, there is no need to To determine whether to adjust the preset group area corresponding to the cluster user terminal one by one, the authorized user can directly add the pre-set cell information list in the static group area to the corresponding preset group area on the GCSE AS side , so as to quickly realize the adjustment of the preset group area and carry out business processing in a timely manner.

It should be understood that, when adjusting the preset group area, a specific adjustment scheme can be given based on the customary scenario of the cluster user terminal, the set static group area and the dynamically changing location information.

Step S204, according to the adjusted preset group area, an update instruction is sent to the core network corresponding to the cluster user terminal, so as to update the group area setting of the core network.

Specifically, after the adjustment of the preset group area is completed, the adjusted preset group area is sent to the MME server, and the MME server stores the adjusted preset group area to the HSS server, and the core network The resource allocation is adjusted and used for subsequent service processing on the cluster user terminal according to the adjusted preset group area.

In addition, issuing an update command to the core network corresponding to the cluster user terminal may be to issue an update command only to the core network where the cluster user is currently located, or to simultaneously send an update command to the core network where the cluster user terminal was located before the location changed. , which can be specifically set according to needs, which is not limited in this embodiment.

Further, the group area adjustment method provided in this embodiment further includes: sending an adjustment instruction to the cluster user terminal according to the adjusted preset group area, so as to adjust the group area parameters of the cluster user terminal.

Specifically, after the GCSE AS adjusts the preset group area, it sends an adjustment instruction to the cluster user terminal according to the adjusted preset group area, and the adjustment instruction includes group area adjustment parameters generated according to the adjusted preset group area.

After the group area is adjusted, when the trunking user terminal initiates the trunking service again, the GCSE AS invokes the preset group area, allocates a shared wireless channel to the cell corresponding to the cell information list in the preset group area, and sends a notification message.

The group area adjustment method provided by the embodiment of the present invention is to set a preset group area for the cluster user; the preset group area includes a cell information list preset for the cluster user; obtain the identification information of the cluster user terminal corresponding to the cluster user; The information adjusts the preset group area corresponding to the cluster user terminal; according to the adjusted preset group area, an update command is sent to the core network corresponding to the cluster user terminal to update the group area setting of the core network. That is, the preset group area corresponding to the cluster user terminal is dynamically adjusted through the identification information of the cluster user terminal, and the group area setting of the core network corresponding to the cluster user terminal is adjusted accordingly, so as to ensure that the cluster user terminal can operate smoothly. Business processing; and the setting and dynamic adjustment of the preset group area can reasonably allocate wireless resources, achieve the effect of optimizing the scheduling area, improve the rationality of system resource allocation, and improve the utilization rate of system resources; of course, it can also expand the system. The capacity of the cluster user terminal. In addition, in the group area adjustment method provided in this embodiment, the setting of the preset group area is based on the GCSE framework. The GCSE framework separates the trunking application from the LTE bearer network, and the architecture is more reasonable; The cluster business can use the setting method and adjustment method of the preset group area, so that the cluster business can be performed more efficiently.

Embodiment two:

This embodiment provides a group area adjustment method, please refer to Figure 5, which specifically includes:

Step S501, reporting identification information to the cluster application server.

Specifically, the cluster user terminal reports its own identification information to the cluster application server, and the specific reporting method includes: actively reporting the identification information to the cluster application server; or receiving an acquisition instruction sent by the cluster application server, and sending the identification information to the cluster application server. That is, the cluster user can actively send its identification information to the GCSE AS when logging in or logging out of its corresponding GCSE Application, or when the location of the cluster user terminal changes, so that the GCSE AS can use the identification information to identify the corresponding cluster user terminal. The preset group area is adjusted; the position of the cluster user terminal changes can specifically mean that the cluster user in the connected state performs cell handover; or the cluster user in the idle state updates the tracking area, or the cluster user in the idle state is tracking District re-election, etc. When the cluster user terminal sends the identification information to the GCSE AS, specifically, the cluster user terminal may send the identification information to the MME, and then the MME forwards the identification information to the GCSE AS. Of course, it is also possible to receive the acquisition request sent by the GCSE AS to the cluster user terminal in real time or regularly, and send the identification information to the cluster application server according to the acquisition request, so that the cluster application server can use the identification information to the preset group area corresponding to the cluster user terminal Make adjustments. Wherein, the identification information may specifically include the identity information, location information, or login status information of the cluster user terminal, and the location information may be the latitude and longitude information of the current location of the cluster user terminal, or may be the information of the cell where the cluster user terminal is currently located .

Step S502, receiving an adjustment instruction sent by the cluster application server, where the adjustment instruction includes group area adjustment parameters generated by the cluster application server after adjusting the preset group area according to the identification information.

Specifically, after the cluster user terminal reports the identification information, if the GCSE AS adjusts the preset group area corresponding to the cluster user terminal according to the identification information, the GCSE AS will send a message containing the group area adjustment parameters to the cluster user terminal. An adjustment instruction, the cluster user terminal receives the adjustment instruction.

In step S503, an adjustment operation of group area parameters is performed according to the adjustment instruction.

Specifically, after receiving the adjustment instruction sent by the GCSE AS, the trunking user terminal sets its local parameters according to the group area adjustment parameters in the adjustment instruction; the group area adjustment parameters specifically include cluster service cell parameters, neighbor cell reselection parameters and some other notification parameters, which are used for the cluster user terminal to complete its own cluster service cell setting according to the group of area adjustment parameters, and to perform cell handover with the optional neighbor cell parameters provided in the group of area adjustment parameters during cell handover. After the setting is completed, the trunking service is initiated according to the setting, and the GCSE AS assigns a shared wireless channel to the cell corresponding to the cell information list in the preset group area according to the call of the preset group area and sends a notification message to perform the trunking service.

The group area adjustment method provided by the embodiment of the present invention reports the identification information to the cluster application server; receives the adjustment instruction sent by the cluster application server, and the adjustment instruction includes adjusting the preset group area corresponding to the user information by the cluster application server according to the location information , the generated group area adjustment parameters; execute the group area parameter adjustment operation according to the adjustment instruction. That is, the group area parameters of the cluster user terminal can be set according to the adjusted preset group area, so that the cluster user terminal can receive the cluster business initiated by the cluster application server for the preset group area, and perform cluster business normally, improving the cluster The stability of the trunking service performed by the user terminal.

Embodiment three:

This embodiment provides a group area adjustment method for PTT (Push to Talk) service in the trunking communication technology, where PTT is also called "Push to Talk", which is a trunking mobile phone service. PTT realizes the mobile voice service of the walkie-talkie (Walkie-Talkie), which has the advantages of short call establishment time, occupying the channel only when talking, and only listening to the channel when answering, and the receiver can receive call information at any time without picking up the phone. MCPTT (Mission Critical Push To Talk based on LTE network) defines the implementation standard of PTT service under LTE network, and designs the call control process at the application layer to realize the perfect voice trunking function. Among them, MCPTT Server is an instance of GCSE AS, which is used to centrally manage key business functions of MCPTT, such as cluster user group management, multicast business management, broadcast business management, speaking right control, group area management, emergency call management, etc. The MCPTT Client is the cluster user agent operated by the MCPTT application, and provides cluster user information and location information for the MCPTT Server.

The group area adjustment method provided in this embodiment, please refer to Figure 6, specifically includes:

In step S601, an authorized user sets a static group area and generates a preset group area.

Specifically, the authorized user sets the static group area of the cluster user group corresponding to the cluster user on the MCPTT Server side, and maps the static group area to a cell in the LTE network, that is, the static group area includes one or more continuous coverage Or the cell information lists of discontinuous wireless cells, select at least several cell information lists from the static group area as required as the preset group area, and the preset group area is the operation group area for business. At this time, the preset group area form of the MCPTT Server is consistent with the group area form in the HSS, and there is a one-to-one correspondence between the cells. At this time, the group area is generally a collection of several ECGI (E-UTRAN Cell Global Identifier, E-UTRAN cell global identifier), wherein the ECGI mainly includes MCC (Mobile Country Code, the country code of the mobile user), NCC (Next Hop Chaining Counter, startled connection counter), eNB ID (E-UTRAN base station identity), CellID. The setting of the static group area can be flexibly set according to actual needs, so as to meet the requirements of relatively stable and relatively changing scenarios of the cluster user terminals in the cluster user group.

Step S602, sending the preset group area to the MME.

In step S603, the MME stores the preset group area in the HSS.

Specifically, the MCPTT Server sends the preset group area set by the authorized user to the MME, and then the MME sends the preset group area to the HSS for storage, so that the HSS can perform grouping based on the stored preset group area During service, network resource allocation is performed, and when group service is performed, service forwarding and bearer are performed on the cluster user terminal according to the preset group area.

Step S604, the trunking user terminal sends identification information to the MME.

In step S605, the MME forwards the identification information sent by the cluster user terminal to the cluster application server.

Specifically, when an MCPTT user logs in or logs out of the MCPTT Client, or when the location changes, it needs to report its own identification information to the MCPTT Server. The identification information includes location information. Specifically, the MCPTT user sends the identification information to the EPC network. The MME unit is then sent to the MCPTT Server by the MME unit. Specifically, the MCPTT User needs to report identification information to the MCPTT Server in the following five situations: (1) When the MCPTT User logs in to the MCPTT Client, the MCPTT Client needs to report its own location information. It can also be logged in through a registered account; (2) When the MCPTT User is in the idle state, the location area changes and the tracking area is updated, and the MCPTT Client needs to report the location information; (3) When the MCPTT User is in the idle state, the location area changes , when reselecting in the tracking area (TAC, Tracking Area Code), MCPTTClient needs to report all cell identities in the tracking group list as changed location information; (4) When the terminal where the MCPTT Client is located performs cell handover in the connected state , MCPTT Client needs to report location information. (5) When the terminal where the MCPTT Client is located logs out, the MCPTT Client needs to report the location information.

Step S606, adjusting the preset group area according to the identification information.

Specifically, after receiving the user identity information and location information reported by the MCPTT Client, the MCPTT Server first searches for the cluster group area to which the MCPTT User belongs according to the user identity information. When in the set group area, start adjustment, add the cell information list corresponding to the location information of the user to the preset group area; or delete the cell information list corresponding to the location information of the cluster user terminal from the preset group area as required; After the adjustment is complete, save the adjusted preset group area.

Step S607, sending the adjusted preset group area to the MME.

Specifically, after the MCPTT Server adjusts the preset group area, in order to ensure that the network deployment matches the adjusted group area, the MCPTT Server needs to send an update command to the EPC to update the group area setting of the EPC; specifically, the The update instruction may include the adjusted preset group area, that is, send the adjusted preset group area to the MME of the EPC.

In step S608, the MME stores the preset group area in the HSS.

Specifically, after receiving the adjusted preset group area sent by the MCPTT Server, the MME stores the adjusted preset group area in the HSS for use in subsequent network resource allocation and cluster service bearing. Here, the format of the adjusted preset group area stored by the HSS is still the cell information list of the cell.

In step S609, the MCPTT Server updates the group parameter information to the MCPTT Clients in the adjusted area.

Specifically, in order to ensure that the MCPTT Client can smoothly perform the cluster business, the MCPTT Server also needs to send an adjustment instruction to the MCPTT Client to adjust the local group area parameters of the MCPTT Client, and the adjustment instruction includes group area adjustment parameters.

In step S610, the MCPTT Client updates group area parameters.

Specifically, after receiving the adjustment instruction sent by the MCPTT Server, the MCPTT Client sets its local parameters according to the group area adjustment parameters in the adjustment instruction. After the setting is completed, the trunking service can be initiated according to the setting, and the MCPTT Server will allocate a shared wireless channel to the cell corresponding to the cell information list in the preset group area according to the call of the preset group area and issue a notification message to perform the trunking service.

Moreover, the discrete nature of the group area requires the network to provide the coverage of the cell in advance, because the network needs to provide sufficient coverage when performing static group area setting or dynamically adjusting the preset group area. When the group area spans multiple networks, the network operator needs to coordinate the configuration, and provide the cross-network configuration function for cluster user group configuration.

In the group area adjustment method provided by the embodiment of the present invention, the preset group area is set for the cluster user terminal on the MCPTT Server side; then the preset group area corresponding to the cluster user terminal is adjusted according to the obtained identification information; and then according to the adjusted The preset group area of the cluster user terminal sends an update command to the core network corresponding to the cluster user terminal to update the group area setting of the core network; and sends an adjustment command to the MCPTT Client to adjust the group area parameters of the MCPTT Client. The preset group area can be dynamically adjusted according to the needs, and the group area settings of the core network and MCPTTClient are also updated and adjusted according to the adjusted preset group area, so that cluster users are no longer limited by the fixed group area. Solved the problem that the business cannot be carried out after the MCPTT Client is removed from the group. That is, the group area adjustment method provided in this embodiment can ensure that the cluster user terminal can smoothly perform business processing, and can also improve the rationality of system resource allocation and improve the utilization rate of system resources.
