Embodiment Construction

[0054] The basic idea of ​​the present invention is that after the target eNodeB returns a handover request confirmation to the source eNodeB, the source eNodeB sends configuration information related to the UE's current eMBMS Session to the target eNodeB; the target eNodeB judges whether the eMBMS Session is currently supported, and if not, sends The MCE sends an indication message; the MCE determines the eMBMS Session that should be restored or reactivated according to the indication message, and sends a session scheduling message or a session start message to the target eNodeB; the target eNodeB deploys the service of the eMBMS Session in the corresponding MBSFN area, and sends it to the target eNodeB MCE returns a response message.

[0055] The technical solutions of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0056] The application scenario of the present invention is: the MBSFN area wher...

Abstract

The invention discloses a method for guaranteeing eMBMS continuity. The method comprises that switching request confirmation is returned to a source evolved node B (eNodeB) from a target eNodeB, and the source eNodeB sends configuration information which relates to a current eMBMS session of user equipment to the target eNodeB; the target eNodeB determines whether the eMBMS session is supported or not currently, and if the eMBMS session is not supported, an indicating message is sent to a multiple custom edge (MCE); the MCE determines the eMBMS session to be restored or reactivated according to the indicating message and sends a session scheduling message or a session starting message to the target eNodeB; and the target eNodeB deploys services of the eMBMS session in a corresponding multimedia broadcast single frequency network (MBSFN) area and returns a response message. The invention also discloses a system. By the aid of the method and the system, the eMBMS continuity after switching is finished can be guaranteed, and current network systems are compatible.

Description

technical field [0001] The present invention relates to enhanced multimedia broadcast or multicast service in a long term evolution system, in particular to a method and system for ensuring business continuity of enhanced multimedia broadcast or multicast service (eMBMS). Background technique [0002] The 3rd Generation Partnership Project (3GPP) introduced the Multimedia Broadcast or Multicast Service (MBMS) feature in the R6 version to realize 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 (LTE) or system architecture evolution (SAE) network architecture, the implementation framework and method of MBMS services at the bearer level have changed. In order to distinguish the previous MBMS bearer impl...
