Service transmission method for multimedia broadcast/multicast service
First Claim
1. A service transmission method for a multimedia broadcast/multicast service (MBMS service) comprising:
- receiving, by a radio network controller (RNC), a session start instruction of the MBMS service from a core network (CN);
selecting, by the RNC, a service bearer mode to carry the MBMS service for a cell that belongs to the RNC; and
providing, by the RNC, the MBMS service using the selected service bearer mode for the cell,wherein the service bearer mode is a point-to-multipoint (PTM) mode or a point-to-point (PTP) mode, and the selecting the bearer mode is based on a characteristic of the MBMS service or a current service load of the cell.

Abstract
The present invention provides a service transmission method for MBMS, comprising: a core network initiates an MBMS service; having received a session start instruction of the MBMS service, the RNC selects the PTM mode or the PTP mode as a service bearer mode to bear the MBMS service for each cell that belongs to the RNC. The method of the invention makes it possible to directly adopt the PTM mode or the PTP mode to bear an MBMS service, skipping the complicated Counting process adopted by the prior art, reducing the complexity of the system, decreasing interaction of signaling of the air interface, and lowering power consumption of the UE.

6. A service transmission method for a multimedia broadcast/multicast service (MBMS service) comprising:
-
receiving, by a radio network controller (RNC), a session start instruction of the MBMS service from a core network (CN); for cells that belong to the RNC, judging, by the RNC, whether an interference between the cells in which there are users requesting the MBMS service is less than a predefined interference threshold; if the interference is less than the predefined interference threshold, selecting a point-to-multipoint (PTM) mode as a service bearer mode to carry the MBMS service for the cells; if the interference is not less than the predefined interference threshold, selecting a point-to-point (PTP) mode as the service bearer mode to carry the MBMS service for the cells; and providing, by the RNC, the MBMS service using the selected service bearer mode for the cells.

7. A service transmission method for a multimedia broadcast/multicast service (MBMS service) comprising:
-
receiving, by a radio network controller (RNC), a session start instruction of the MBMS service from a core network (CN), wherein the session start instruction contains a bearer mode indication; selecting, by the RNC, a point-to-multipoint (PTM) mode or a point-to-point (PTP) mode according to the bearer mode indication; and providing, by the RNC, the MBMS service using the selected service bearer mode for a cell that belongs to the RNC.

9. A radio network controller (RNC) comprising:
-
a receiving unit, configured to receive a session start instruction of a multimedia broadcast/multicast service (MBMS service) initiated by a core network, a selecting unit, configured to select a point-to-multipoint (PTM) mode or a point-to-point (PTP) mode as a service bearer mode according to a characteristic of the MBMS service or a current load of a cell that belongs to the RNC; and a providing unit, configured to provide the MBMS service using the selected service bearer mode for the cell. - View Dependent Claims (10, 11, 12, 13)
