As shown in fig. 1, a method for processing a multimedia broadcast service according to a first embodiment of the present application includes:

s101, determining the service flow included in the target session and the mapping relation between the service flow and the preset radio bearer.

It should be noted that the executing subject of the processing method for multimedia broadcast service in the embodiment of the present application may be an access network device, where the access network device includes, but is not limited to, a radio access network device (NG-RAN) and the like.

It is to be understood that one target session may include one or more traffic flows. Further, a mapping relationship between the traffic flow and a preset radio bearer may also be determined. Alternatively, one traffic flow may be mapped to a unique radio bearer, and a plurality of different traffic flows may be mapped to the same radio bearer.

Optionally, the determining a mapping relationship between the service flow and the preset Radio bearer may include determining a mapping relationship between the service flow and the preset Radio bearer according to a local Radio Resource Management (RRM) policy.

For example, if it is determined that the target session a includes the service flow 1, the service flow 2, and the service flow 3 according to the session context information, and the preset radio bearer may include the radio bearers MRB 1 and MRB 2, it may be determined that the service flow 1 and the service flow 2 are mapped to the radio bearer MRB 1 and the service flow 3 is mapped to the radio bearer MRB 2 according to the RRM policy.

It is to be understood that a plurality of service flows may be included in the target session, and then the plurality of service flows included in the target session may be grouped according to the mapping relationship, as the grouping information of the target session.

Optionally, generating the packet information of the target session according to the mapping relationship may include treating the service flows mapped to the same radio bearer as the same packet.

For example, if the target session a includes traffic flow 1, traffic flow 2, and traffic flow 3, and it is determined that traffic flow 1, traffic flow 2 are mapped to radio bearer MRB 1, and it is determined that traffic flow 3 is mapped to radio bearer MRB 2, the packet information of the target session a may constitute packet 1 for traffic flow 1 and traffic flow 2, and packet 2 for traffic flow 3.

S103, the grouping information is sent to the core network equipment.

Optionally, sending the packet information to the core network device may include the following two possible implementations:

mode 1, sending a session resource establishment response message including packet information to a core network device.

It is to be understood that, after generating the packet information of the target session, the access network device may generate a session resource establishment response message including the packet information, and transmit the session resource establishment response message to the core network device, so that the packet information may be transmitted to the core network device.

Mode 2, the interface message including the grouping information is sent to the core network equipment.

It is to be understood that, after generating the packet information of the target session, the access network device may further generate an interface message including the packet information, and transmit the interface message to the core network device, so that the packet information may be transmitted to the core network device.

Optionally, when the access network device is an NG-RAN, the NG-RAN may send NG interface signaling including packet information to the core network device.

And S104, receiving the data packet sent by the core network equipment and the serial number of the data packet, wherein the serial number of the data packet is obtained by the core network equipment according to the grouping information.

The sequence number of the radio bearer may be a Packet Data Convergence Protocol (PDCP) sequence number.

To sum up, according to the method for processing a multimedia broadcast service according to the embodiment of the present application, an access network device can generate packet information of a session according to a mapping relationship between a service flow and a radio bearer in the session and send the packet information to a core network device, and then can receive a data packet number generated by the core network device according to the packet information, and then can determine a sequence number of the radio bearer corresponding to the data packet according to the data packet number and the packet information, thereby ensuring continuity of receiving the data packet by a user equipment.

On the basis of any of the foregoing embodiments, determining the service flow included in the target session in step S101 may include receiving a session resource establishment request sent by the core network device, where the session resource establishment request includes session context information of the target session, and then determining the service flow included in the target session according to the session context information.

Optionally, obtaining the number of the data packet according to the grouping information may include separately numbering the data packets in the service flows in different groups according to the grouping information, and uniformly numbering the data packets in the service flows in the same group to obtain the number of the data packet.

For example, if the packet information of the target session a may be that the service flow 1 and the service flow 2 constitute a packet 1, and the service flow 3 constitutes a packet 2, the data packets in the service flow 1 and the service flow 2 in the packet 1 may be numbered according to 1, 2 to N, and the data packets in the service flow 3 in the packet 2 may also be numbered according to 1, 2 to N, where the number of the data packets of the service flow 1 and the service flow 2 in the packet 1 overlaps with the number of the data packet of the service flow 3 in the packet 2.

Further, in order to avoid the situation that the numbers of the data packets in the service flows in different packets are repeated, the numbers of the data packets can carry the identifications of the service flows or the identifications of the packets.

Alternatively, if the number of the data packet C in the traffic flow 2 in the packet 1 is 14, the number of the data packet C may be 214, where 2 is used to characterize that the data packet C belongs to the traffic flow 2, and 14 is used to characterize that the number of the data packet C in the packet 1 is 14.
