Embodiment Construction

[0063] In order to activate the MBMS service of a designated evolved base station (Evolution Node B, eNB), in this embodiment, first, the user equipment (User Equipment, UE), eNB or multicast coordination entity (Multi-cell / multicast Coordination Entity, The MCE) specifies an eNB based on the measurement result obtained after the measurement, and requests to activate the MBMS service when it finds that the MBMS service has not been activated according to the MBMS service information of the specified eNB. In this embodiment, the designated eNB is called a target eNB, and the eNB to which the UE belongs is called a source eNB. In this embodiment, an LTE system is taken as an example for description.

[0064] This embodiment provides multiple methods for activating the MBMS service of a designated eNB. For example, the first method is to activate the MBMS service of the target eNB when the UE in the standby state performs cell measurement and finds that the target eNB that meets ...

Abstract

The present invention provides a method of activating MBMS, for realizing MBMS of appointed evolution base station. The method includes following steps: determining the object evolution base station; judging whether the object evolution base station transmitting MBMS or not; when the object evolution base station being not transmit MBMS, transmitting the first information for adding object evolution base station in the content distribution tree and transmitting radio resource distribution information to the object evolution base station by the MCE. The invention also provides an user equipment, an evolution base station, a MCE and a communication system.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and a system for activating multimedia broadcast and multicast service. Background technique [0002] With the development of wireless network technology, it has developed from a Universal Mobile Telecommunications System (UMTS) to a Long Term Evolution (LTE) system. LTE is an evolution standard based on UMTS network formulated by 3GPP organization. LTE greatly improves the transmission capability of the physical layer and reduces the complexity of the system. [0003] Among them, the technology of Multimedia Broadcast / Multicast Service (MBMS) has also been greatly improved. MBMS was introduced in the R6 version of UMTS for the first time, using the UMTS network to provide MBMS services. MBMS refers to broadcasting or multicasting multimedia data to mobile terminals by sharing a transmission link. MBMS is divided into broadcast and multicast two working modes. Wherein, the...
