Embodiment Construction

[0060] The technical solutions of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0061] The present invention adopts in the LTE system, after the network side activates or deactivates the MBSFN transmission mode according to the feedback information of receiving the MBMS service state reported by the UE, the core network determines the transmission path of the MBMS service, and the access network configures the corresponding radio bearer of the MBMS service resource. Such as figure 1 As shown, the dotted lines in the figure respectively show the PTP transmission path and the MBSFN transmission path.

[0062] The core network includes at least one of the following network elements: BM-SC, MME, MBMS gateway, and PDN gateway; the access network includes at least one of the following network elements: MCE, eNB. The transmission path refers to the path from the BM-SC to the UE; after determining the...

Abstract

The invention discloses a method and a system for converting a transmission mode of multimedia broadcast multicast service (MBMS). The method comprises the following steps that: after a network side activates or deactivates the transmission mode of a multimedia broadcast single frequency network (MBSFN) according to feedback information, which is reported by user equipment (UE), for receiving the state of the MBMS, a core network determines a transmission path of the MBMS; and an access network configures corresponding radio bearing resources of the MBMS. By the invention, by determining the transmission path of the MBMS and the corresponding radio bearing resources after activating or deactivating the transmission mode of the MBSFN of the MBMS, service continuity is guaranteed, and user experience is improved.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method and system for converting transmission modes of Multimedia Broadcast Multicast Service (MBMS, Multimedia Broadcast Multicast Service) in a Long Term Evolution (LTE, Long Term Evolution) system. Background technique [0002] In order to effectively utilize mobile network resources, the 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project) proposed the MBMS service, that is, a point-to-multipoint service that provides a data source to send data to multiple users in the mobile network, and the MBMS service realizes It improves the sharing of network resources and improves the utilization of network resources, especially the precious air interface resources. The MBMS technology studied in the LTE network is called Evolved Multimedia Broadcast Multicast Service (E-MBMS, Evolved MBMS). [0003] In the existing LTE technology, the logical c...
