Problems solved by technology

When the MCS of the MCCH changes, the UE will update the system information. Assuming that the UE obtains the new MCS of the MCCH in the new system information at T1, the UE will use the new MCS to receive the MCCH at T2. Since the MCS of the MCCH will be Time T3 changes, so at time T2, MCCH still uses the old MCS, and UE receives MCCH according to the new MCS at time T2, which will cause the UE to fail to receive MCCH correctly, which in turn will result in the inability to receive MBMS services and affect user experience

Abstract

The embodiment of the invention discloses a transceiving method, device and system of a MCCH (Multicast Control Channel). The method comprises the following steps of: receiving MCCH configuration information and the effective time information of the MCCH configuration information for coordinating MCE (Multi-VPN-Instance Customer Edge) from multimedia broadcasting and multicast service by base station equipment; generating a system information block according to the MCCH configuration information and the effective time information of the MCCH configuration information and sending the system information block to UE (User Equipment) by base station equipment; and sending the MCCH by the base station equipment according to the MCCH configuration information and the effective time information of the MCCH configuration information so that the UE receives the MCCH by using the MCCH configuration information in the system information block. The embodiment of the invention improves the correct receiving rate of the MCCH and can better provide the MBMS (Model Base Management System) service.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method, device and system for transmitting and receiving MCCH. Background technique [0002] In the field of third-generation mobile communication technology, the LTE (Long Term Evolution, Long Term Evolution) R9 (Release 9, version 9) system introduces the MBMS (Multimedia Broadcast Multicast Service) mechanism, through MCCH (Multicast Control Channel, multicast control channel) transmits MBMS control information, and BCCH (Broadcast Control Channel, broadcast control channel) transmits MCS (Modulation and Coding Scheme, modulation and coding format) information of MCCH. If the MCS of the MCCH received by the UE (User Equipment, user equipment) through the BCCH is different from the MCS used for the current MCCH transmission, an MCCH reception error will be caused, further causing the UE to fail to receive the MBMS service normally and affecting user exper...
