Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

MCPTT is a service provided by 3GPP for public safety and rail transportation to support user communication, which supports multiple users to communicate (group call) and also supports communication between two users (single call). The method has the key advantage that the establishment, maintenance and interruption of communication among users are realized based on a long-term evolution architecture. The 3GPP started research work on MCPTT in 2014, and released Long Term Evolution (LTE) R13 standard release in 2016. However, in the current 3GPP MCPTT protocol, as long as the user signs up and is interested in the group, the group service can be listened to, regardless of the location of the area where the user is located, so the current 3GPP MCPTT protocol cannot meet the use requirement of the area group.

The application provides a regional group communication method, which adjusts the interest relationship of a terminal device to a regional group through the current position of the terminal device, thereby limiting the effective regional range of the regional group, making up the deficiency of a 3GPP MCPTT protocol and meeting the use requirement of the regional group.

The regional group communication method provided by the application can be applied to an LTE communication trunking system, and the system comprises User Equipment (UE), an MCPTT server and a Group Management Server (GMS). The following will briefly introduce each part of the LTE communication trunking system:

the UE is a user equipment capable of accessing multiple group calls simultaneously, may be a mobile terminal, such as a handheld terminal, or may be a fixed terminal, such as a debugging station, and establishes a connection with the MCPTT server through a broadband wireless access system, where the broadband wireless access system includes multiple evolved node bs (eNodeB, eNB) and the like that establish a trunking service session radio bearer.

The MCPTT server is a network-side system device, and is configured to manage and control a system trunking service, specifically including establishment, maintenance, and release of the trunking service, forwarding of trunking service data, notification of trunking service information change, and the like, and is responsible for management and scheduling of a talk right, management of a single call and a group call, and the like. The MCPTT server transmits a message to the UE through a Session Initiation Protocol (SIP).

The GMS is configured to store subscription information of the UE, where different UEs may subscribe to different groups, the same UE may subscribe to multiple groups, and the GMS establishes group information for the different groups, where the group information includes information such as an identifier of the group and an identifier of the user equipment that subscribes to the group.

The following describes a transmission processing method provided by the present application with some specific embodiments.

Fig. 1 is a flowchart illustrating a first embodiment of a regional group communication method according to an embodiment of the present application, where the method of the present embodiment is applied to a UE, as shown in fig. 1, in the present embodiment, the regional group communication method includes:

s101, when the resident cell is changed, the current first position is obtained.

In this step, when the UE moves, and the cell or the base station where the UE is located changes, it is necessary to acquire the current location of the UE in order to determine whether the UE is still within the effective area range of the service of the relevant area group.

Wherein the first location refers to a current location of the UE. In one possible implementation, the UE acquires the first location through a global positioning system installed in the UE; in another possible implementation, the UE acquires the first location through the MCPTT server by sending a location acquisition request to the MCPTT server.

S102, establishing an interest relation/non-interest relation with the regional group according to the first position and the configuration relation of the signed group.

In this step, in order to enable all subscribed users entering the effective area range of the area group to receive the group message and enable users outside the effective area range of the area group (no matter whether the users are subscribed or not) not to listen to the group message, after S101, the UE establishes an interest relationship or a non-interest relationship with the area group according to the first location obtained in S101 and the stored configuration relationship of the subscribed group, that is, the UE refreshes the interest relationship with the area group to define the effective range of the area group.

The configuration relationship of the subscription group may be one or multiple. When the subscription group configuration relationship is one, the identification information of all the area groups subscribed by the UE and the effective area range corresponding to each area group are stored in the subscription group configuration relationship, and when the UE subscribes a new area group, the subscription group configuration relationship needs to be updated, that is, the newly added area group and the effective area range thereof are added into the subscription group configuration relationship; when the subscription group configuration relationship is multiple, each regional group corresponds to a single subscription group configuration relationship, that is, each subscription group configuration relationship includes one regional group subscribed by the UE and an effective region range of the regional group, and the UE subscribes to several regional groups, the subscription group configuration relationships will be several. The effective area range is used for representing the coverage of signals of the area group, with the granularity of a cell (or a base station). The subscription group configuration relationship may be stored in the UE in a form of a data table.

Establishing a non-interest relationship with the regional group may be understood as canceling an interest relationship with the regional group.

It is understood that the effective ranges of the area groups may overlap, that is, the same cell may be included in the effective ranges of the area groups, for example, the effective range of the area group S1 includes cell a, and the effective range of the area group S2 also includes cell a, so that cell a is included in the effective ranges of the area groups S1 and S2.

S103, selecting whether to listen to the message broadcasted by the MCPTT server or not according to the interest relation/non-interest relation with the regional group.

In this step, after S102, according to the established interest relationship or non-interest relationship with the regional group, the UE selects whether to listen to the message broadcasted by the MCPTT server, specifically, the UE listens to the message broadcasted by the MCPTT server of the regional group with the interest relationship, but does not listen to the message broadcasted by the MCPTT server of the regional group with the non-interest relationship.

For example, the MCPTT server broadcasts a group message, where the group message includes an identifier of the group, and the UE checks whether the group corresponding to the message has an interest relationship with itself, and listens to the message if the interest relationship exists, or does not listen to the message otherwise.

The message broadcasted by the MCPTT server may be a multicast message, or may be a unicast message or a broadcast message.

In this embodiment, when a resident cell is changed, an interest relationship/non-interest relationship with an area group is established by acquiring a current first position, and according to the first position and a subscription group configuration relationship, where the subscription group configuration relationship includes an identifier of the area group subscribed by the UE and an effective area range thereof, and then according to the interest relationship/non-interest relationship with the area group, whether to listen to a message broadcasted by a task key push-to-talk MCPTT server is selected, and the interest relationship or the non-interest relationship with the area group is set according to the current position of the UE, so as to limit the effective area range of the area group, and ensure that all subscribers in the effective distinguishing range can listen to the message broadcasted by the corresponding area group, while subscribers not in the effective area range or subscribers in the effective area range cannot listen to the message broadcasted by the corresponding area group, makes up the deficiency of the 3GPP MCPTT protocol and meets the use requirement of the regional group.

Fig. 2 is a flowchart illustrating a second embodiment of a regional group communication method according to an embodiment of the present application, where based on the embodiment shown in fig. 1, as shown in fig. 2, in this implementation, S102 includes:

s1021, whether the first position is in the effective range of the regional group in the signed group configuration relationship is judged.

In this step, after S101, the UE determines whether the current first location is included in the effective area range of one or more area groups by querying the subscription group configuration relationship.

Wherein the first location may be a first cell in which the UE is currently located, and if the effective range of the area group is also in a cell-based granularity, in a possible implementation manner, the subscription group configuration relationship includes information of all area groups subscribed by the UE, by comparing an identifier of the first cell in which the UE is currently located with identifiers of cells in the effective area ranges of all area groups subscribed by the UE in the subscription group configuration relationship, it is determined whether one or more area groups including the first cell exist, if one or more area groups including the first cell exist, it is determined that the first location is within the effective range of one or more area groups in the subscription group configuration relationship, and if one or more area groups not including the first cell exist, it is determined that the first location is not within the effective range of one or some area groups in the subscription group configuration relationship, one or more regional groups containing the first location are found.

In another possible implementation manner, each subscription group configuration relationship only includes information of one area group subscribed by the UE, and by comparing the first cell with each effective area range of the area group in each subscription group configuration relationship, if a cell having the same identifier as the first cell is found in the effective area range of the area group, it is determined that the first location is within the effective area range of the area group in the subscription group configuration relationship, otherwise, it is determined that the first location is not within the effective area range of the area group in the subscription group configuration relationship, and so on, according to the same method, all subscription group configuration relationships in the UE are traversed, and all area groups including the first location are found.

S1022, if the first location is within the valid area range of the area group in the signed group configuration relationship, determining whether there is an interest relationship with the area group including the first location in the signed group configuration relationship.

In this step, if it is determined through S1022 that the first location is within the effective area range of the one or more area groups, it is further determined whether an interest relationship already exists between the first location and the one or more area groups, so as to determine which area groups need to establish an interest relationship, so as to ensure that an interest relationship exists between the first location and all area groups including the first location.

S1023, if the interest relation does not exist, sending a first request for establishing the interest relation to the MCPTT server, wherein the first request comprises the identification of one or more regional groups needing to establish the interest relation and the identification of the UE.

In this step, after S1022, if it is determined in S1022 that there is no interest relationship with one or some of the regional groups including the first location, an interest relationship establishment request, that is, a first request, is sent to the MCPTT server, where the first request includes an identifier of one or more regional groups and an identifier of the UE that need to establish an interest relationship, so that the MCPTT server establishes an interest relationship between the UE and the corresponding regional group according to the first request.

The absence of interest relationship includes two cases, one case is that no interest relationship exists between the first location and all the area groups including the first location, and the other case is that no interest relationship exists between part of the area groups in all the area groups including the first location.

The identifier of the area group is used for uniquely determining one area group, and may be a name of the area group or a number of the area group.

The UE identity is used to uniquely identify a UE, and may be a sequence number of the UE, etc.

Illustratively, when a UE subscribes to 10 regional groups S1, S2, S3, S4, S5, S6, S7, S8, S9 and S10, when the UE moves cell a, it is determined through S1021 that there are S1, S2, S3, S4 and S5 of the regional group containing cell a, and through S1022, it is found that the UE already has an interest relationship with S1, S2 and S3 of the regional group and does not have an interest relationship with S4 and S5 of the regional group, and thus, in S1023, the UE sends a first request to the MCPTT server, the first request including the identities of the regional groups S4 and S5 to request the MCPTT server to establish an interest relationship between the UE and S4 and S5.

Optionally, the method further comprises:

and receiving a first response message sent by the MCPTT server, wherein the first response message is used for indicating that the interest relationship between the UE and the requested regional group is established.

Illustratively, based on the above example, the UE receives a first response message sent by the MCPTT server, where the first response message is used to notify the UE that the MCPTT server has established an interest relationship with the regional groups S4 and S5, and the UE can listen to the message broadcasted by the regional groups S4 and S5.

In this embodiment, whether the first location is within an effective area range of an area group in the subscription group configuration relationship is determined, if the first location is within the effective area range of the area group in the subscription group configuration relationship, whether an interest relationship exists between the first location and the area group including the first location in the subscription group configuration relationship is determined, and if no interest relationship exists, a first request for establishing the interest relationship is sent to the MCPTT server, where the first request includes an identifier of one or more area groups in which the interest relationship needs to be established and an identifier of the UE, so that the UE establishes the interest relationship with all area groups including the first location, and thus the UE can listen to messages covering all area groups at its current location, which is favorable for ensuring that the area group service is performed smoothly.

Fig. 3 is a flowchart illustrating a third embodiment of a regional group communication method according to an embodiment of the present application, where based on the embodiment shown in fig. 2, as shown in fig. 3, in this embodiment, S102 further includes:

and S1024, if the first position is not in the effective area range of the partial area group in the signed group configuration relationship, judging whether a non-interest relationship exists between the first position and the area group which does not include the first position in the signed group configuration relationship.

In this step, after S1021, if it is determined that the first location is not within the effective area range of one or some area groups in the contracted group configuration relationship through S1022, it is further determined whether a non-interest relationship already exists between the first location and the one or more area groups, so as to determine which area groups need to establish a non-interest relationship, so as to ensure that a non-interest relationship exists between the first location and all area groups that do not include the first location, that is, an interest relationship is cancelled between the first location and all area groups that do not include the first location.

And S1025, if no non-interest relationship exists, sending a second request for establishing the non-interest relationship to the MCPTT server, wherein the second request comprises the identification of one or more regional groups needing to establish the non-interest relationship and the identification of the UE.

In this step, after S1024, if it is determined in S1024 that there is no non-interest relationship with one or some of the regional groups that do not include the first location, a non-interest relationship establishment request, that is, a second request, is sent to the MCPTT server, where the second request includes the identifier of the one or more regional groups that need to establish the non-interest relationship and the identifier of the UE, so that the MCPTT server establishes the non-interest relationship between the UE and the corresponding regional group according to the second request, that is, cancels the interest relationship between the UE and the corresponding regional group.

The non-interest relationship does not exist, and the other condition is that the non-interest relationship does not exist between the partial region groups in all the region groups not including the first position.

Illustratively, a UE subscribes to 10 regional groups S1, S2, S3, S4, S5, S6, S7, S8, S9, and S10 one by one, when the UE moves to cell a, it is determined through S1021 that the regional group not including cell a includes S6, S7, S8, S9, and S10, and through S1024, it is found that the UE has a non-interest relationship with the regional group therein between S6, S7, S8, and S9 and does not have a non-interest relationship with the regional group S10 (i.e., there is an interest relationship), and thus, in S1025, the UE sends a second request to the MCPTT server, which includes an identification of the regional group S10, to request the MCPTT server to establish the non-interest relationship between the UE and S10 (cancel the existing interest relationship).

Optionally, the method further comprises:

and receiving a second response message sent by the MCPTT server, wherein the second response message is used for indicating that the non-interest relationship between the UE and the requested regional group is established (the interest relationship is cancelled).

Illustratively, based on the above example, the UE receives the second response message sent by the MCPTT server, where the second response message is used to notify the UE that the MCPTT server has established a non-interest relationship with the regional group S10, and the UE does not hear the message broadcasted by the regional group S10.

In this embodiment, by determining whether the first location is within an effective area range of an area group in the subscription group configuration relationship, if the first location is within the effective area range of the area group in the subscription group configuration relationship, determining whether an interest relationship exists between the first location and the area group including the first location in the subscription group configuration relationship, and if no interest relationship exists, sending a first request for establishing the interest relationship to the MCPTT server, where the first request includes an identifier of one or more area groups and an identifier of the UE, where the one or more area groups need to establish the interest relationship; if the first position is not in the effective area range of the partial area group in the signed group configuration relationship, judging whether a non-interest relationship exists between the first position and the area group which does not contain the first position in the signed group configuration relationship, if the non-interest relationship does not exist, sending a second request for establishing the non-interest relationship to the MCPTT server, wherein the second request comprises the identification of one or more area groups which need to establish the non-interest relationship and the identification of UE, according to the first position, traversing the effective area ranges of all the area groups signed by the UE to distinguish the area group containing the first position and the area group which does not contain the first position, analyzing the relation between the area group containing the first position and the area group which does not contain the first position and the UE, and combing the interest relationship and the non-interest relationship of the area group corresponding to the UE again, therefore, the UE has interest relation with all the regional groups containing the first position and has non-interest relation with the regional groups not containing the first position, so that the UE can be ensured to listen to the messages covering all the regional groups at the current position of the UE, but not listen to the messages not covering all the regional groups at the current position of the UE, the use requirement of the regional groups is met, and the smooth operation of regional group services is further facilitated.

Fig. 4 is a flowchart illustrating a fourth embodiment of a regional group communication method according to an embodiment of the present application, where based on the foregoing embodiments, as shown in fig. 4, in the embodiment of the present application, before S102 or S1021, the method further includes:

and S1001, receiving the subscription group configuration relationship sent by the GMS.

In this step, before the UE performs further action using the subscription group configuration relationship, the UE needs to obtain the subscription group configuration relationship from the GMS, and uses the identifier of the subscription area group and its effective area range of the UE

In a first possible implementation manner, after the GMS generates the subscription group configuration relationship, the GMS actively sends the subscription group configuration relationship to the UE, and the UE stores the received subscription group configuration relationship and calls the subscription group configuration relationship when the subscription group configuration relationship needs to be used.

The implementation mode has the advantages that the subscription group configuration relationship is convenient to use, interaction with the GMS is not needed before use, and time is saved.

In a first possible implementation manner, before the UE needs to use the subscription group configuration relationship, the UE sends a subscription group configuration relationship acquisition request to the GMS, triggers the GMS to send the subscription group configuration relationship to the UE, and the UE temporarily stores (for example, stores by caching) the subscription group configuration relationship and releases the subscription group configuration relationship after use.

The implementation mode has the advantages that the UE does not need to be divided into memories for separately storing the configuration relationship of the subscription group, and the built-in resources of the UE are saved.

The specific method is selected according to the actual use needs and application scenarios, and the inventor does not limit the method.

Fig. 5 is a schematic flowchart of a fifth embodiment of a regional group communication method according to an embodiment of the present application, and on the basis of the embodiment shown in fig. 4, as shown in fig. 5, this embodiment is applicable to a second possible implementation manner in the fourth embodiment, and the regional group communication method in this embodiment further includes:

s1002, receiving an update message of the subscription group configuration relationship sent by the GMS.

In this step, because the effective area range of the area group changes, in order to ensure that the UE establishes an accurate interest relationship and a non-interest relationship with the area group, the UE receives an update message of the subscription group configuration relationship from the GMS, so as to update the subscription group configuration relationship stored in the UE.

Wherein the update message includes an identification of the changed regional group and the changed content.

The mark of the changed area group is used for positioning the changed area group; the content of the change is specific change items, and is divided into a change of the area group and a change of the effective range of the area group, and specifically, the following items are included:

the change of the area group includes addition of the area group or deletion of an original area group, for example, the UE signs a new area group or cancels a subscription relationship with some area groups, and the change of the area group is determined by the change of the subscription relationship between the UE and the area group. For example, a certain area group S1 originally includes three cells, cell a, cell B, and cell C, and due to update, upgrade, rearrangement, or the like of the communication network, the changed area group S1 includes four cells, cell a, cell B, cell C, and cell D, and the change of the effective area range of the area group is determined by the change of the communication network.

And S1003, updating the subscription group configuration relationship according to the updating message.

In this step, after S1002, the UE updates the corresponding zone group or the effective zone area of the zone group in the subscription group configuration relationship according to the identifier and the change content of the changed zone group in the update message.

Updating the subscription group configuration relationship is divided into two possible cases: one is a signed group configuration relationship, and the signed group configuration relationship is updated by updating corresponding items in the signed group configuration relationship, such as addition, deletion, information change and the like of the items; and the other subscription group configuration relations are multiple, and the update of the subscription group configuration relations is completed by changing the corresponding subscription group configuration relations or the information in the subscription group configuration relations, such as the addition and deletion of the subscription group configuration relations or the change of the information in part of the subscription group configuration relations.

In this embodiment, by receiving the subscription group configuration relationship and the update message of the subscription group configuration relationship sent by the GMS, where the update message includes the identifier and the change content of the changed area group, the subscription group configuration relationship is updated according to the update message, so that the UE can master the latest information of the subscription group configuration relationship, the accuracy of analyzing the area group including the first location by the UE is improved, thereby ensuring that the UE establishes a correct interest relationship with the area group including the first location, ensuring that the UE acquires the message of the corresponding area group in time, and improving the communication quality of the area group service.

Fig. 6 is a flowchart illustrating a sixth embodiment of a regional group communication method provided in an embodiment of the present application, where the method in this embodiment is applied to a GMS, and as shown in fig. 6, the regional group communication method in this embodiment includes:

s201, when the regional group is opened, the effective regional range of the regional group is configured.

In this step, in order to limit the range in which the regional group can be listened to, when the regional group is opened, the effective area of the regional group is bound, and thus the effective area range of the regional group is determined.

For example, when the area group S1 opens an account, the effective area ranges configured for S1 are cell 1, cell 2, cell 3, and cell 4, which means that users located in cell 1, cell 2, cell 3, and cell 4 can listen to the message broadcasted by the area group S1, and users located outside cell 1, cell 2, cell 3, and cell 4 cannot listen to the message broadcasted by the area group S1 even if they subscribe to the group.

S202, generating a signing group configuration relation of the regional group according to the effective regional range.

In this step, a subscription group configuration relationship of the area group is generated according to the effective area range configured for the area group in S201, where the subscription group configuration relationship includes the identifier of the area group and the effective area range determined in S201.

Illustratively, on the basis of the above example, the generated subscription group configuration relationship may be S1 (cell 1, cell 2, cell 3, cell 4).

S203, sending the signed group configuration relation to the UE and the MCPTT server.

In this step, the GMS sends the subscription group configuration relationship generated in S202 to the UE and the MCPTT server so that the UE and the MCPTT server can use the subscription group configuration relationship as well.

In one possible implementation, the GMS configures the subscription group configuration relationship to the UE and the MCPTT server through a group file.

In another possible implementation manner, the GMS may further store subscription information of different UEs and service range information of different MCPTT servers, so as to send the subscription group configuration relationship to the required UE and the MCPTT server.

In this step, the GMS may actively send the generated subscription group configuration relationship to the UE and the MCPTT server, or may send the subscription group configuration relationship to the corresponding UE and the MCPTT server when receiving an acquisition request of the UE and the MCPTT server.

In this embodiment, the GMS configures an effective area range of the area group when the area group opens an account, generates a subscription group configuration relationship of the area group according to the effective area range to limit a range in which the area group can be listened to, and then sends the subscription group configuration relationship to the UE and the MCPTT server, so that the UE and the MCPTT server perform corresponding operations according to the subscription group configuration relationship, thereby ensuring smooth performance of the area group service.

Fig. 7 is a flowchart illustrating a seventh embodiment of a regional group communication method according to an embodiment of the present application, where based on the embodiment shown in fig. 6, as shown in fig. 7, the regional group communication method according to the present embodiment further includes:

s204, when the configuration relationship of the signed group changes, sending an update message of the configuration relationship of the signed group to the UE and the MCPTT server.

In this step, in an actual application process, due to various reasons, the subscription group configuration relationship of the regional group may be changed, and in order to ensure that the subscription group configuration relationship between the UE and the MCPTT server is synchronized with the subscription group configuration relationship in the GMS, when the subscription group configuration relationship is changed, the GMS needs to send an update message of the subscription group configuration relationship to the UE and the MCPTT server, where the update message includes an identifier of the changed regional group and change content, so that the UE and the MCPTT server update the corresponding subscription group configuration relationship according to the update message.

In this embodiment, when the subscription group configuration relationship is changed, the synchronization between the subscription group configuration relationship between the UE and the MCPTT server and the subscription group configuration relationship in the GMS is ensured by sending an update message of the subscription group configuration relationship to the UE and the MCPTT server, which is further beneficial to ensuring the benign operation of the regional group communication system and ensuring the high efficiency and smoothness of the regional group communication.

Fig. 8 is a flowchart illustrating a seventh embodiment of a regional group communication method according to an embodiment of the present application, where the present embodiment is applied to an MCPTT server, and as shown in fig. 8, the regional group communication method in the present embodiment includes:

s301, receiving the subscription group configuration relationship sent by the GMS.

In this step, the MCPTT server receives a subscription group configuration relationship sent by the GMS, where the subscription group configuration relationship includes an identifier of a regional group and an effective region range thereof.

Optionally, after S301, the method for regional group communication in this embodiment further includes:

receiving an update message of the subscription group configuration relationship sent by the GMS, wherein the update message comprises an identification of a changed regional group and a changed content;

And S302, determining the area range of the broadcast message according to the configuration relationship of the subscription group and the interest relationship and/or the non-interest relationship of the corresponding UE.

In this step, when the MCPTT server receives the message broadcast request, in order to enable the message to reach the corresponding UE, the MCPTT server needs to determine a set of distribution ranges of UEs interested in the message according to the subscription group configuration relationship and the interest relationship and/or the non-interest relationship of the corresponding UE, and further determine an area range in which the message is broadcast.

Illustratively, if the broadcast required by the current MCPTT server is a multicast message of a certain regional group, the MCPTT server determines which UEs subscribing to the regional group are according to the subscription group configuration relationship, then determines the UEs having an interest relationship with the regional group according to the interest relationship and/or non-interest relationship of the UEs subscribing to the regional group, and then selects a corresponding region to establish a group call according to the set of the current location of the UEs having an interest relationship with the regional group, thereby reducing occupation and waste of resources as much as possible while ensuring that all UEs having an interest relationship with the regional group are covered.

And S303, broadcasting the message to the determined area range for broadcasting the message.

In this step, after S302, the MCPTT server broadcasts the message to the area range of the broadcast message determined in S302, so that the UEs interested in the corresponding area group can all listen to the message broadcasted by the MCPTT server.

In one possible implementation, the MCPTT server broadcasts the message by message.

In addition, the manner in which the MCPTT server broadcasts the message may be multicast, unicast, multicast, or the like, which is not limited by the inventor.

In this embodiment, by receiving a subscription group configuration relationship sent by the GMS, where the subscription group configuration relationship includes an identifier of a region group and an effective region range thereof, determining a region range in which to broadcast a message according to the subscription group configuration relationship and an interest relationship and/or a non-interest relationship of a corresponding UE, and broadcasting the message to the region range, all UEs having an interest relationship with the region group can listen to the message broadcasted by the MCPTT server, thereby ensuring validity and usefulness of the message, ensuring smooth performance of a region group service, and improving public safety.

S402, establishing the interest relationship between the UE and one or more regional groups according to the first request.

In this step, after S401, according to the received first request, an interest relationship between the UE sending the first request and one or more area groups that need to establish an interest relationship and are included in the first request is established.

In one possible implementation, the MCPTT server configures, for each UE, a first list of regional groups with which the UE has an interest relationship, where the first list is changed, and the MCPTT server adaptively adjusts, each time the MCPTT server receives a first request, the first list according to the first request, for example, adding one or more regional groups in the first request to the first list.

Optionally, the area group communication method further includes:

and sending a first response message to the UE, wherein the first response message is used for notifying the UE that the interest relationship between the UE and the requested regional group is established.
