First, the service and related concepts of the MBMS applied in the embodiment of the present invention are introduced.

MBMS uses the "point-to-multipoint" method to simultaneously send data sent by the same service source to multiple UEs, which improves network resource utilization through bearer and resource sharing. MBMS can be used in LTE to implement MBMS, that is, all communities that provide MBMS services in the MBSFN area transmit the same content on the same time and frequency resources. With the MBSFN technology, the UE can combine signals from multiple communities to obtain diversity and gain, and improve signal reception quality.

The same MBMS service can be transmitted in different MBSFN areas, that is, different MBSFN areas can belong to the same MBMS service area. As shown in FIG. 1, although there are three MBSFN areas, they belong to one MBMS service area. Different MBSFN areas can overlap.

Below, the network architecture of the LTE MBMS system is introduced.

Figure 2 is a network architecture diagram of the LTE MBMS system. As shown in FIG. 2, the LTE MBMS system includes the following logical entities: MME; MBMS Gateway (MBMS Gateway, MBMS GW); MCE; Evolved Node B (eNodeB); Group Communication System Enabler (Group) The Communications System Enabler (GCSE) application server, an application server that implements group communication services in the LTE MBMS system, supports the group communication service by the MBMS bearer or the unicast bearer; and the UE runs the GCSE application.

When the group communication service is carried by the unicast, the UE transmits the data of the group communication service between the S-GW and the P-GW and the GCSE application server.

The LTE MBMS system has the following interface: M3: Provides session management related functions between the MME and the MCE, such as: session start (session start), session stop (session stop) notification; M2: provides session between the MCE and the eNodeB. Manage and deliver MBMS scheduling information and other functions; M1: providing MBMS service transmission between the MBMS GW and the eNodeB; GC1: interface between the GCSE application server and the GCSE application on the UE; Uu: an empty interfacing plane between the UE and the eNodeB.

The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

FIG. 3 is a schematic structural diagram of a processing system of a group communication service according to an embodiment of the present invention. As shown in FIG. 3, the system includes: a first network side device 301, configured to determine that a specific group communication service of a specific community needs to be switched from an MBMS bearer to a unicast bearer, and notify the second network side device 302 to which the specific community belongs. Stopping the specific group communication service on the MBMS bearer in the specific community; the second network side device 302 is configured to: after receiving the notification information sent by the first network side device 301 to stop the specific group communication service on the MBMS bearer in the specific community, Stop transmitting the service data of the specific group communication service on the MBMS bearer, and notify the UE in the specific community that the specific group communication service is in progress to establish a unicast bearer for carrying the specific group communication service; the UE 303 is configured to receive the second network side. The device 302 sends a notification for establishing a unicast bearer for a specific group of communication services, and establishes a unicast bearer for carrying a specific group of communication services.

In the embodiment of the present invention, the first network side device 301 may be a GCSE application server in the LTE MBMS system, and the second network side device 302 may be an eNodeB in the LTE MBMS system, and the GCSE application is run on the UE.

Hereinafter, an embodiment of the present invention will be described in detail by taking an LTE MBMS system as an example. Although the LTE MBMS system is taken as an example here, it does not mean that the embodiment of the present invention can only be applied to LTE. MBMS system. In fact, any operation group communication service needs to be switched to a unicast bearer system for a specific community to carry the group communication service, and the bearer switching of the group communication service for a specific community can be implemented by using the embodiment of the present invention.

The GCSE application server determines that there is a need to switch a specific group communication service of a specific community from an MBMS bearer to a unicast bearer. For example, the GCSE application server performs real-time monitoring on the number of UEs in the specific community that perform the specific group communication service. When the number of UEs is less than the preset first UE number threshold, and the group of communication services in the specific community is being carried by the MBMS, it is determined that the specific group communication service of the specific community needs to be switched from the MBMS bearer to the unicast bearer.

In the embodiment of the present invention, the GCSE application server may notify the eNodeB to stop the MBMS bearer of the specific group communication service in the specific community in two ways: mode 1: notification for stopping the specific group communication service on the MBMS bearer in the specific community The information is sent to the eNodeB through the MBMS gateway, the MME, and the MCE. The second method is to send the notification information of the specific group communication service on the MBMS bearer in the specific community to the eNodeB through the UE in the RRC connection state in the specific community. .

In the second mode, the GCSE application server may first send the notification information to the UE in the RRC connection state in the specific community through the GC1 interface in FIG. 2, and then the UE sends the notification information to the eNodeB through the Uu interface in FIG. 2.

Optionally, for mode 1, the foregoing notification information may include: a community identifier of a specific community and an identifier of a specific group communication service, respectively, used to indicate a specific community and a specific group communication service; and may also include a community name and a specific group of the specific community. The name of the communication service, as long as it can refer to The specific community and the specific group communication service may be displayed; for the second mode, the identifier of the specific group communication service may be included in the notification information to indicate the specific group communication service. Here, unlike the first method, the GCSE application server does not need to send information for identifying a specific community, because in the second mode, the UE receiving the notification information is in an RRC connected state, and the community to which it belongs is In the specific community, when the UE sends the foregoing notification information to the eNodeB, the eNodeB is aware of the community to which the UE belongs, and the eNodeB only needs to notify the UE in the community to which the UE belongs to the UE that is performing the specific group communication service, so as to notify the specific community. The UE stops using the MBMS to carry the purpose of the specific group communication service. Here, the UE notified by the eNodeB is a UE that is in the community to which the UE that receives the notification information of the GCSE application server is performing the specific group communication service, and includes the UE that receives the notification information of the GCSE application server.

Optionally, the notification information further includes: time information that the eNodeB stops transmitting the service data of the specific group communication service on the MBMS bearer.

The time information may indicate a specific moment after the GCSE application server sends the notification information, and may also indicate a time interval after the notification information is sent from the GCSE application server. The GCSE application server sends the time information to instruct the eNodeB to stop sending the service data of the group of communication services on the MBMS bearer after receiving the notification, so that the UE has sufficient time to establish the group. The unicast bearer of the communication service avoids the interruption of the group communication service.

The GCSE application server can set the time information in the notification information according to the configuration data set by the network maintenance personnel for configuring the time information, and can also compare the communication delay between the GCSE application server and the eNodeB according to the past statistics. The UE establishes a unicast bearer. Time statistics to determine the time information so as to avoid interruption of the group communication service. Optionally, the time information is not suitable for setting too large, avoiding the base station from performing unnecessary business data processing, and wasting the community of the specific community. Resources. For example, it can be set to 5s, 8s, etc.

Optionally, after receiving the foregoing notification information sent by the GCSE application server, the eNodeB may send a stop MBMS bearer to the UE in the specific community that is performing the specific group communication service by using System Information or by using the MCCH. After receiving the instruction, the UE sends a request to establish a unicast bearer message through the RRC signaling and the GCSE application server, and the GCSE application server establishes a message to establish a unicast bearer after receiving the request. A unicast bearer used to carry the set of communication services.

Optionally, the foregoing instruction may include an identifier of a specific group communication service or a service name of the specific group communication service to indicate the specific group communication service.

Optionally, when the GCSE application server determines that a specific group communication service of a specific community needs to be switched from a unicast bearer to an MBMS bearer (for example, the GCSE application server immediately monitors the number of UEs that perform the specific group communication service in a specific community. If the second threshold of the preset number of UEs is greater than or equal to the first threshold of the number of UEs in the foregoing, and the group of communication services in the specific community is being carried by the unicast, it is determined that the specific group communication service of the specific community needs to be The unicast bearer is switched to the MBMS bearer).

Optionally, when the GCSE application server determines that the specific group communication service of the specific community needs to be switched from the unicast bearer to the MBMS bearer, the GCSE application server first sends a stop to the specific community to the eNodeB to stop the unicast in the specific community. The notification information carrying the specific group communication service, optionally, the notification information includes a community identifier indicating the specific community. After receiving the notification information, the eNodeB establishes in the specific community to carry the specific group. The MBMS bearer of the communication service, and the UE that performs the specific group communication service in the specific community sends an instruction to perform the specific group communication service (using system information or through the MCCH) on the MBMS bearer, and the specific community performs the specific After receiving the instruction, the UE of the group communication service will use the MBMS bearer to receive the service data of the specific group communication service. Optionally, the unicast bearer for carrying the specific group communication service in the specific community may be deleted.

In the existing scheme of stopping the session by means of the TMGI, the stop of the MBMS service is detected based on the manner implemented by the UE, and the interruption time of the group communication service is long, and the service continuity requirement of the group communication cannot be met, and the embodiment of the present invention is provided. A preferred scheme for switching an MBMS bearer to a unicast bearer (including time information indicating a time at which the eNodeB stops transmitting service data of a specific group communication service on the MBMS bearer in the notification information), thereby leaving a longer period for the UE Time establishes a unicast bearer, which minimizes or avoids the interruption of the group communication service.
