Method, system and base station for achieving multimedia broadcast multicast service (MBMS) dedicated carrier network establishing

Abstract

The invention discloses a method, a system and a base station for achieving multimedia broadcast multicast service (MBMS) dedicated carrier network establishing. According to the method, the base station deploys MBMS dedicated carriers to at least one cell covered by a carrier with a downlink synchronization mechanism; the MBMS dedicated carriers and the carrier with the at least one downlink synchronization mechanism are set to keep downlink synchronization; and user equipment (UE) performs downlink synchronization with the carrier with the downlink synchronization mechanism according to the downlink synchronization mechanism. By means of the method, the system and the base station for achieving MBMS dedicated carrier network establishing, an MBMS dedicated carrier network can be efficiently established, the UE and the carrier with the downlink synchronization mechanism achieve downlink synchronization, simultaneously, the UE and the MBMS dedicated carriers also achieve downlink synchronization, radio resource utilization ratio of the MBMS dedicated carriers is increased, and the phenomenon that the UE without MBMS capacities are mistakenly accessed to the MBMS dedicated carriers is avoided.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a method, system and base station for realizing dedicated carrier networking for Multimedia Broadcast Multicast Service (MBMS). Background technique [0002] With the rapid development of the Internet and the popularization of large-screen multifunctional mobile phones, a large number of mobile data multimedia services and various high-bandwidth multimedia services have emerged, such as: video conferencing, TV broadcasting, video on demand, video advertising, online education, interactive games, etc. , which not only meets the ever-increasing business demands of mobile users, but also brings new business growth points to mobile operators. These mobile data multimedia services require multiple users to receive the same data at the same time. Compared with general data services, they have the characteristics of large data volume, long duration, and delay sensitivity. In...

Problems solved by technology

However, due to the slow progress of the standardization work, the MBMS dedicated carrier technology is currently blank in the upper layers of LTE

[0004] The existence of MBMS-dedicated carriers, for early version user equipment (UE), or UEs without MBMS capabilities, since MBMS-dedicated carriers do not provide unicast services, it will cause such UEs to mistakenly access MBMS-dedicated carriers
