US 8,798,657 B2 · Method and device for transmitting multimedia broadcast multicast service control information

Abstract

The present invention discloses a method and a device for transmitting multimedia broadcast multicast service control information. The method comprises: a base station stopping transmission of an MBMS service in a cell, and transmitting control plane information of the MBMS service, wherein, in the control plane information, contents of an SIB2, MCCH information and DSI remain unmodified, and contents of an SIB13 are modified or remain unmodified. The device comprises: a service stopping unit, configured to stop transmission of an MBMS service in a cell; a transmitting unit, configured to transmit control plane information of the MBMS service in the cell in which the MBMS service is stopped, wherein in the transmitted control plane information, contents of an SIB2, MCCH information and DSI remain unmodified, and contents of an SIB13 are modified or remain unmodified. The present invention improves reliability of receiving an MBMS service by a UE.

Dependent claims

A method for transmitting multimedia broadcast multicast service control information, comprising:

a base station stopping transmission of a Multimedia Broadcast Multicast Service (MBMS) service in a cell, and transmitting control plane information of the MBMS service in the cell in which the MBMS service is stopped, wherein in the control plane information, contents of a System Information Block (SIB) 2, Multimedia Control Channel (MCCH) information and Dynamic Scheduling Information (DSI) remain unmodified, and contents of an SIB13 are modified or remain unmodified, wherein the contents of the SIB2 remaining unmodified comprises:
after the base station stops the transmission of the MBMS service, allocation of multicast resources in a Multicast Broadcast Single Frequency Network (MBSFN) area corresponding to the stopped MBMS service remaining unmodified;
the contents of the MCCH information remaining unmodified comprises:
the MCCH information still comprising related information about the stopped MBMS service;
and the contents of the DSI remaining unmodified comprises:
the MCCH information still comprising related information about the stopped MBMS service.
