The regions MBSFN configuration information corresponding to each SAI for each adjacent cell that S201, base station obtain current area.
Specifically, can interact the regions the MBSFN configuration information of respective serving cell between base station, base station is receiving other
After the regions the MBSFN configuration information for each serving cell that base station is sent, for some current serving cell, the cell is determined
Each adjacent cell each SAI corresponding to the regions MBSFN configuration information.
When S202, base station determine that the first SAI of the first adjacent cell and each SAI of current area ownership are different from, or
One of the SAI that the first SAI of person is belonged to by current area, and the first adjacent cell belongs to the difference of the first SAI with current area
When the regions MBSFN, the regions the MBSFN configuration information corresponding to the first SAI of the base station by the first adjacent cell is broadcast to UE.
Specifically, belong to the different regions MBSFN of the first SAI from current area for the first adjacent cell, base station can be with
By the corresponding areas MBSFN the first SAI for comparing the corresponding regions the MBSFN ID of the first SAI and current area of the first adjacent cell
Domain ID is determined, when the two difference, indicates that the first adjacent cell belongs to the different regions MBSFN of the first SAI from current area.
