All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terms "comprises" and "comprising," and any variations thereof, in the description and claims of this invention, are intended to cover non-exclusive inclusions, e.g., a process or an apparatus that comprises a list of steps is not necessarily limited to those structures or steps expressly listed but may include other steps or structures not expressly listed or inherent to such process or apparatus.
Fig. 1 is a flowchart of a method for handling a broadcast group call based on a regional location according to an embodiment of the present invention, where the method may be executed by a broadcast group call handling apparatus, and in practical applications, the apparatus may be embodied as a hardware entity with a broadcast group call handling function, such as a server. As shown in fig. 1, the method includes:
The service area referred in this embodiment refers to a broadcast area providing a broadcast group call service, and the corresponding relationship between the group identifier and the service area identifier referred in this embodiment is established according to a binding relationship between different groups and broadcast areas set in advance. For example, fig. 2 is a schematic diagram of a binding relationship between a group and a broadcast area according to an embodiment of the present invention, in which a group a is bound to a broadcast area 200, and a group b is bound to a broadcast area 403 and a broadcast area 401, that is, the broadcast area of the group a is the broadcast area 200, and the broadcast areas of the group b are the broadcast areas 403 and 401. The correspondence between the group identity and the service area identity established according to the binding shown in fig. 2 includes the correspondence between the identity of group a and the identity of broadcast area 200, and the correspondence between the identity of group b and the identities of broadcast areas 401 and 403.
Optionally, in this embodiment, the broadcast group call processing apparatus further stores a nesting relationship between service areas. Still taking fig. 2 as an example, if the service area 301 is nested in the service area 200 (i.e. the broadcast area 200) in fig. 2, and the service areas 403 and 401 (i.e. the broadcast areas 403 and 401) are nested in the service area 301, the nested relationship among the service area 200, the service area 301, the service area 403 and the service area 401 is stored in the broadcast group call processing device. It is understood that this is by way of illustration only and is not meant as an exclusive limitation of the present application.
In practical application, when the broadcast group call processing apparatus finds the first service area corresponding to the target group, the broadcast group call service of the terminal device is broadcast in the first service area or one or more service areas nested in the first service area according to the locally stored nesting relationship.
Optionally, in this embodiment, one or more service areas may be selected from the first service area according to a preset policy, and then the broadcast group call service of the terminal is broadcast in the selected one or more service areas through the MBMS transmission network.
Optionally, in a possible implementation manner, the broadcast group call service including the service area broadcast terminals whose number of users meets the preset condition is selected from the first service area. For example, in practical applications, a broadcast group call service including a service area broadcast terminal with the largest number of users in the first service area may be selected. It is understood that this is by way of illustration and not by way of limitation.
For example, fig. 3 is a schematic diagram of a nesting relationship between service areas according to an embodiment of the present invention, as shown in fig. 3, a service area 201 and a service area 202 are nested in a service area 100, a service area 301 and a service area 302 are nested in the service area 201, and a service area 303 and a service area 304 are nested in the service area 202. If the group a is a target group, the first service area corresponding to the group a is the service area 100, and the number of users in the service area 201 is the largest, the broadcast group call service of the terminal is broadcast in the service area 201.
In this embodiment, by pre-establishing the corresponding relationship between the group identifier and the service area identifier, when the terminal initiates the broadcast group call request, the service area corresponding to the group is searched according to the corresponding relationship and the identifier of the group carried in the broadcast group call request, and the broadcast group call service of the terminal is broadcasted in the service area by using the MBMS transmission network, so that the broadcast group call service can be realized without establishing the corresponding relationship between the group and the members, the implementation manner of the broadcast group call is simplified, the resource waste of the system is avoided, and the efficiency of the system is improved.
Fig. 4 is a flowchart of a broadcast group call processing method based on a regional location according to another embodiment of the present invention, as shown in fig. 4, on the basis of the embodiment shown in fig. 3, the method provided by this embodiment includes:
In this embodiment, by pre-establishing the corresponding relationship between the group identifier and the service area identifier, when the terminal initiates the broadcast group call request, the service area corresponding to the group is searched according to the corresponding relationship and the identifier of the group carried in the broadcast group call request, and when the first service area corresponding to the target group is not found, the broadcast group call service of the terminal is broadcast in the whole network, so that the broadcast group call service can be realized without establishing the corresponding relationship between the group and the member, the implementation manner of the broadcast group call is simplified, the resource waste of the system is avoided, and the efficiency of the system is improved.
Fig. 5 is a signaling flowchart of a broadcast group call processing method based on a zone location according to an embodiment of the present invention, in which the broadcast group call processing apparatus is specifically a cluster application server, as shown in fig. 5, the signaling flowchart includes:
s1, the UE1 initiates a broadcast group call request to the cluster application server, where the request is in the specific form of a Session Initiation Protocol (SIP) message REFER, and the REFER message carries an identifier of the target group.
S2, the cluster application server replies a success response to the UE 1.
S3, the cluster application server judges unicast and multicast of the terminal in the service area corresponding to the target group, wherein it is assumed that the receiving terminal UE2 and UE3 adopt multicast;
the operation of the cluster application server for executing the unicast and multicast decision further comprises: checking whether the service area for broadcasting is overlapped with other service areas initiating broadcasting simultaneously, if so, the cluster application server can only initiate one of the broadcasting group calling services belonging to the overlapped area according to the strategy.
S4, the cluster application server sends a session Burst control protocol (TBCP) CONNECT message to the UE1 to bind the UE1 uplink session and the SIP session.
S5, UE1 sends a TBCP Acknowledgement (ACK) message to the cluster application server.
S6, the cluster application server sends a talk burst GRANTED TBCP FLOOR GRANTED message to UE1 informing UE1 that talk burst is GRANTED.
S7, the cluster application server sends the Group bearing binding Map Group To Bearer message To MB2-U interface of MBMS transmission network, the message carries the broadcast service identification.
S8, the MBMS transport network forwards the MapGroupToBearer message to UE2 and UE3 using a multicast channel.
S9a, UE2 and UE3 determine that the SIP pre-established session state is not currently associated with other group services (i.e. in the not _ in _ use state), and determine that the broadcast group call service needs to be received.
S9b, if the receiving terminal UE2 or UE3 is currently receiving the service of other groups (i.e. the SIP pre-established session state is in _ use), the terminal decides whether to monitor the broadcast group call service immediately according to the priority policy; such as: the priority policy specifies that the priority of the broadcast group call service is lower than the emergency call and higher than the ordinary group call, and if the receiving terminal is currently listening to other non-emergency call groups, the broadcast group call service is also monitored immediately.
S10, UE1 sends the broadcasted media surface uplink to the cluster application server.
S11, the cluster application server sends the media surface downlink to the MBMS transmission network.
S12, MBMS transmission network sends media surface down to the multicast channel for receiving terminal;
s13, the cluster application server sends the Floor token message to the MBMS transmission network periodically through the MB2-U interface. S13 is not in sequence with S12.
S14, the cluster application server sends the broadcast group calling service downlink to the multicast channel for the receiving terminal through the MBMS transmission network.
In this embodiment, by pre-establishing the corresponding relationship between the group identifier and the service area identifier, when the terminal initiates the broadcast group call request, the service area corresponding to the group is searched according to the corresponding relationship and the identifier of the group carried in the broadcast group call request, and the broadcast group call service of the terminal is broadcasted in the service area by using the MBMS transmission network, so that the broadcast group call service can be realized without establishing the corresponding relationship between the group and the members, the implementation manner of the broadcast group call is simplified, the resource waste of the system is avoided, and the efficiency of the system is improved.
