Fig. 2 is a flowchart of embodiments of a multicast service sending method provided by the present invention, and as shown in fig. 2, the method specifically includes the following steps:

201. the base station acquires configuration information of a Single cell multimedia point-to-multipoint Control Channel (SC-MCCH) for broadcasting a multicast service, wherein the configuration information comprises a Radio Network Temporary Identity (MCCH-Radio Network Temporary Identity, MCCH-RNTI) corresponding to the SC-MCCH and scheduled sending time information of the SC-MCCH Control message.

The executing subject of the multicast service sending method provided by the invention is a multicast service sending device, and the multicast service sending device can be a base station or other servers for sending the service data of the multicast service. The receiver of the service data of the multicast service may be a user equipment subscribing to the multicast service. The point-to-multipoint control channel SC-MCCH is used for transmitting configuration information or SC-MCCH control messages and the like. The configuration information may be pre-configured by the base station and transmitted to the UEs subscribing to the multicast service through the SC-MCCH channel.

In this embodiment, the base station may allocate a radio network temporary identifier MCCH-RNTI to the control channel SC-MCCH, so that the UE may obtain the SC-MCCH control message from the SC-MCCH channel according to the MCCH-RNTI.

202. The base station acquires the scheduled sending time information of the service data of the multicast service.

In this embodiment, the base station allocates Single cell MBMS traffic channels (SC-MTCHs) and their corresponding G-RNTIs for each multicast service, and configures transmission time information for the service.

203. And the base station judges whether the scheduled transmission time information of the SC-MCCH control message and the scheduled transmission time information of the service data of the multicast service are overlapped.

In this embodiment, the base station may compare the scheduled transmission time information of the service data of the multicast service with the scheduled transmission time information of the SC-MCCH control message to determine whether there is an overlap, where the service data of the multicast service generally needs to use multiple periods of the SC-MTCH channel to complete transmission, that is, the scheduled transmission time information of the service data of the multicast service may be multiple time periods corresponding to the multiple periods of the SC-MTCH channel, and at this time, the base station needs to compare the multiple time periods of the service data of the multicast service with the scheduled transmission time information of the SC-MCCH control message respectively to determine whether there is an overlap.

In this embodiment, the information of the scheduled transmission time of the SC-MCCH control message may include: a repetition period and offset parameters of the SC-MCCH control message; the scheduled transmission time information of the service data of the multicast service includes: a repetition period and an offset parameter of the service data of the multicast service. Correspondingly, step 203 may specifically be: determining the subframe position of the SC-MCCH control message in an SC-MCCH channel according to the repetition period and the offset parameter of the SC-MCCH control message; determining the subframe position of the service data of the multicast service in the SC-MTCH channel according to the repetition period and the offset parameter of the service data of the multicast service; and judging whether the subframe position of the SC-MCCH control message in the SC-MCCH channel is overlapped with the subframe position of the service data of the multicast service in the SC-MTCH channel. The repetition period of the SC-MCCH control message may specifically indicate a sequence number or an ordinal number of a period used for transmitting the SC-MCCH control message, and the offset parameter may indicate a specific time period in the corresponding period used for transmitting the SC-MCCH control message.

204. If the scheduled transmission time information of the SC-MCCH control message is overlapped with the scheduled transmission time information of the service data of the multicast service, the base station adjusts the scheduled transmission time information of the service data of the multicast service according to a preset offset parameter so as to ensure that the scheduled transmission time information of the SC-MCCH control message is not overlapped with the scheduled transmission time information of the service data of the multicast service; or multiplexing the SC-MCCH control message and the service data of the multicast service, and sending the multiplexed data block to the UE according to the G-RNTI corresponding to the multicast service.

In this embodiment, in an implementation scenario, the preset offset parameter is N subframes, where N is a positive integer, and correspondingly, the process of adjusting the scheduled transmission time information of the service data of the multicast service according to the preset offset parameter may specifically be to push the scheduled transmission time information of the service data of the multicast service back by N subframes or push it back by N subframes, as shown in fig. 3, a schematic diagram of pushing the scheduled transmission time information of the service data of the multicast service back by 2 subframes is shown.

In a second implementation scenario, the preset bias parameter is a preset time window. Correspondingly, the process of adjusting the scheduled transmission time information of the service data of the multicast service according to the preset offset parameter may specifically be to postpone or advance the scheduled transmission time information of the service data of the multicast service in a preset time window corresponding to the scheduled transmission time information. As shown in fig. 4, it is a schematic diagram that the scheduled transmission time information of the service data of the multicast service is pushed within a preset time window corresponding to the scheduled transmission time information.

In this embodiment, the preset offset parameter may be an offset parameter preset by the base station and each UE, or an offset parameter preset by the base station and received by the UE.

, based on the foregoing embodiment, the configuration information of the multicast service may further include a radio network temporary identity G-RNTI allocated by the base station for the multimedia broadcast multicast service channel SC-MTCH or a temporary multicast group identity TMGI of the multicast service.

Correspondingly, the process of multiplexing the SC-MCCH control message and the service data of the multicast service can be specifically realized by multiplexing a TMGI mark of the multicast service or a radio network temporary identifier G-RNTI allocated by a base station for an SC-MTCH channel, the service data of the multicast service and the SC-MCCH control message into a data block to obtain a multiplexed data block, wherein the multiplexed data block comprises the SC-MCCH control message, the TMGI mark or the G-RNTI and the service data of the multicast service corresponding to the TMGI mark or the G-RNTI.

Wherein, the Temporary Multicast Group Identifier (TMGI) of the multicast service is only to identify the multicast service, and corresponds to the multicast service .

In addition, it should be noted that the TMGI indication or the G-RNTI corresponding to the service data of the multicast service may also be represented by a multiplexing identifier, such as a th multiplexing identifier, a second multiplexing identifier, etc., which may only be to indicate the service data of the multicast service, in addition, if the scheduled transmission time information of the SC-MCCH control message overlaps with the scheduled transmission time information of the service data of the multiple multicast services, the base station may multiplex the SC-MCCH control message and the service data of the multiple multicast services in the same data block, as shown in fig. 5, which is a schematic diagram of the multiplexed SC-MCCH control message obtained by multiplexing the SC-MCCH control message and the service data of the 2 multicast services in the same data block.

In this embodiment, the base station obtains the scheduled transmission time information of the SC-MCCH control message and the scheduled transmission time information of the service data of the multicast service, when the scheduled transmission time information of the SC-MCCH control message and the scheduled transmission time information of the service data of the multicast service overlap, adjusting the preset sending time information of the service data of the multicast service or multiplexing the SC-MCCH control message and the service data of the multicast service, so that in case that the scheduled transmission time information of the SC-MCCH control message and the scheduled transmission time information of the service data of the multicast service overlap, the UE can receive the SC-MCCH control message and the service data of the multicast service, thereby avoiding the UE from missing the service data of the multicast service and improving the sending efficiency and the receiving efficiency of the service data of the multicast service.
