Abstract

The invention discloses a communication system, a communication method and a device thereof. The communication system provided by the invention realizes separation of a multicast service control function and a multicast transmission management function. The communication system comprises a multicast session management network element, an access and mobility management network element and a user plane network element. The multicast session management network element sends a first multicast session request to the access and mobility management network element, the first multicast session requestcarries a multicast session context, and the first multicast session request is used for requesting to establish a multicast session according to the multicast session context; a second multicast session request is sent to a user plane network element, the second multicast session request carries user plane forwarding related information and used for indicating a user plane forwarding rule of themulticast session; The access and mobility management network element receives the first multicast session request and sends the first multicast session request to the access network node; And the user plane network element receives the second multicast session request and sets a user plane forwarding rule of the multicast session according to the user plane forwarding information.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to a communication system, a communication method and a device thereof. Background technique [0002] With the development of 3GPP technology, multicast business scenarios emerge in endlessly, such as group call service, remote upgrade of IoT device software, Internet of Vehicles, broadcasting and television services, etc. [0003] Such as figure 1 As shown, a long term evolution (long term evolution, LTE) based multimedia broadcast / multicast service (multimedia broadcast / multicast service, MBMS) network architecture diagram in the prior art. Wherein, the network elements related to MBMS at the core network side include: broadcast-multicast service center (broadcast-multicast servicecentre, BM-SC) and multimedia broadcast / multicast gateway (MBMS gateway, MBMS GW). MBMS GW can be deployed independently or combined with other network elements (such as BM...
