Embodiment 1

[0027] This embodiment provides a method for cell reselection to ensure eMBMS service continuity. The main content of the method is: in the case of triggering cell reselection, if the UE in the RRC_IDLE state is currently receiving eMBMS services, then When performing cell reselection, the UE needs to make a decision based on the configuration information on the multicast control channel (Multicast ControlChannel, MCCH) of the target reselected cell: determine whether the target reselected cell supports the continuity of its current eMBMS service; , then the UE initiates an RRC connection establishment request to the current camping cell / base station; after the RRC connection is established, the UE reports the identity information of the target reselection cell through a newly added RRC message and expects the target reselection cell to provide The eMBMS service list (Temporary Mobile Group Identity List, TMGI List), the identity information of the target reselected cell can be...

Abstract

The invention discloses a method for ensuring eMBMS service continuity for community reselection. The method comprises the steps that in the situation of meeting the triggering condition of community reselection, if UE in an RRC_IDLE state currently has eMBMS service which is being received, the US needs to determine whether the target reselection community supports the current eMBMS service continuity or not according to configuration information on a multicast control channel of a target reselection community in community reselection; if not, the UE initiates an RRC connection establishment request to a current residence community / base station; and after RRC connection establishment, the UE reports the identification information of the target reselection community through an added RRC message and hopes the target reselection community to provide an eMBMS service list in an MBSFN mode. The method of the invention can better ensure the eMBMS service continuity of UE in an RRC_IDLE state through the mechanism, thereby positively improving service quality experience of users.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and relates to a method for ensuring eMBMS service continuity in cell reselection. Background technique [0002] The 3rd Generation Partnership Project (3GPP) introduced the Multimedia Broadcast / Multicast Service (MBMS) feature in the R6 version, which realizes the simultaneous transmission of data from a data source to multiple users within a specific range A point-to-multipoint service that enables network resources to be shared, thereby providing multimedia services to a large number of users with the same needs at the same time with less resources. Under the long-term evolution / system architecture evolution (Long Term Evolution / System Architecture Evolution, LTE / SAE) network architecture, some changes have taken place in the implementation framework and method of the MBMS service at the bearer level. We call it for eMBMS. [0003] One of the more important changes in eMBMS is...
