- the PTM data is sent to another cell.
- the base station may directly transmit the PTM data received from the MBMS gateway to the first cell through the sending module 32.
- the sending module 32 needs to send a multicast join request message to the MBMS gateway before transmitting the data on the scheduled PTM transmission resource according to the indication of the configuration information. That is, if the base station does not initiate scheduling PTM transmission in any cell, the base station first needs to send a multicast join request message to the MBMS gateway through the sending module 32 to request to join the multicast service. The receiving module 33 then receives the data sent by the MBMS gateway, which is PTM data. At this time, the transmitting module 32 can transmit the data received from the MBMS gateway on the scheduled PTM transmission resource according to the indication of the configuration information.
- the base station provided in this embodiment solves the problem that the base station that has not joined the multicast service performs group communication on the basis of the embodiment shown in FIG.

- the upper-layer network device can learn the coverage of each cell, so that the cell where the UE is located can be determined according to the collected location information of the UE.
- the upper-level network device may determine whether to initiate scheduled PTM transmission in the cell according to the number of UEs in each cell. If the number of UEs in a certain cell exceeds a preset threshold, it may determine that the scheduled PTM transmission is started in the cell.
- the processing module 31 may determine to start scheduling PTM transmission in the first cell.
- the base network device determines whether to initiate scheduling PTM transmission in the first cell according to the number of UEs in the first cell, and notifies the base station to start scheduling PTM transmission in the first cell when the number of UEs in the first cell exceeds a preset threshold.
