Table one MBMS business information reporting process
| Basic process | Initial message |
| The report of MBMS business information | The report of MBMS business information |
Base station c obtains the information of its adjacent base station according to the adjacent cell list that configures among the c of base station, for example, comprise base station a and b in this neighbour's station list, and then base station c initiates MBMS business information reporting process to adjacent base station a and b.
The information relevant with this schedule information comprises and is used to indicate the information that is used for the MBSFN subframe of the professional transmission of MBMS by base station c scheduling, or is used to indicate that base station c reserves and is not used for the information of MBSFN subframe by this base station c scheduling.
During the information of the MBSFN subframe of directly being dispatched by this base station alternately to adjacent base station when system configuration indication base station, the sign of the MBSFN subframe that base station c directly will be dispatched by base station c offers adjacent base station a and b.For example, when MCE indication base station c actual schedule MBSFN subframe 0-4 is used for the MBSFN transmission, the MBSFN subframe that base station c sends to adjacent base station a and b be designated 0-4.
Replacedly, when system configuration indication base station during to the information of the mutual MBSFN subframe of not dispatched by this base station of adjacent base station, base station c is according to the MBSFN subframe of reserving for base station e, and the MBSFN subframe of being dispatched by base station c, carry out the difference computing, the remaining sign of MBSFN subframe of keeping for base station c and not being scheduled for the MBSFN transmission of base station c is offered adjacent base station a and b.For example, base station c reserves 10 MBSFN subframe 0-9 and is used for the MBSFN transmission, and MCE indication base station c actual schedule MBSFN subframe 0-4 is used for the MBSFN transmission.Then in step S22, base station c is through the difference computing, and the remaining sign 5-9 of MBSFN subframe of MBSFN transmission that keeps for base station c and be not scheduled for base station c as the information relevant with scheduling in the MBMS business information, is offered base station a and b.
