CHANNEL SYNCHRONIZATION METHOD, SYSTEM AND DEVICE IN MULTICAST BROADCAST SINGLE FREQUENCY NETWORK
First Claim
1. A channel synchronization method in a multicast single frequency network, comprising:
- a network device in the multicast single frequency network acquiring Multimedia Broadcast and Multicast Service, MBMS, service information and determining time resources and a frequency resource over which the MBMS service information is borne;
the network device transmitting the MBMS service information and information on the time resources and the frequency resource to base stations in the multicast single frequency network; and
the base stations in the multicast single frequency network transmitting the MBMS service information to a user equipment over an MBMS point-to-multipoint Control Channel, MCCH, over the time resources and the frequency resource.

Abstract
A channel synchronization method, system and device in the multicast broadcast single frequency network are disclosed, which relate to wireless communication filed and are used to solve the problem of unable to ensure the base station to synchronously send the multi-points control channel (MCCH) message in the multicast broadcast single frequency network (MBSFN) region in the prior art. The specific scheme is: the network device in the MBSFN obtains multimedia broadcast multicast service (MBMS) service information and confirms the time resource and the frequency resource that bears MBMS service information. The network device sends the MBMS service information, the time resource and the frequency resource information to the base station in the MBSFN. The base station utilizing the time resource and the frequency resource sends the MBMS service information to the terminal via MBMS point to MCCH. Consequently the purpose that the base station synchronously sends the MBMS service message in the MBSFN is achieved.
