Embodiment Construction

[0073] Currently provided multicast session establishment schemes such as figure 1 As shown, a CP (Content Provider, content provider) network element sends multicast service information to a PCF (Policy Control Function, policy control function) network element, and after receiving the multicast service information, the PCF network element generates PCC (Policy Control and Charging, policy control and charging) rules. When a terminal device requests to join the multicast service, the SMF (SessionManagement Function, session management network element) network element corresponding to the terminal device determines the QoS (Quality of Service, quality of service) of the multicast service according to the PCC rule flow information, and send the QoS flow information of the multicast service to the base station. After receiving the QoS flow information of the multicast service, the base station configures a corresponding radio bearer for the QoS flow of the multicast service.

Abstract

The present application relates to the technical field of communication, and discloses a multicast session management method and device, the method comprising: receiving a first message from a first session management network element, the first message being used for requesting quality of service (QoS) flow information of a multicast service; and sending the QoS flow information to the first session management network element. According to the method, the main body for sending the QoS flow information is the same, the information of the QoS flow is the same, and no matter the number of the SMFs is one or more, the information of the QoS flow of the multicast service received by each SMF is the same, so that the success rate of establishing the multicast session is improved.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a method and device for managing a multicast session. Background technique [0002] With the development of the mobile Internet, video services account for an increasing proportion of data services. At the same time, users are gradually changing from traditionally watching popular programs through fixed TVs to watching popular programs through mobile Internet through UE (User Equipment, terminal equipment) (such as mobile phones or notebook computers, etc.). Therefore, the impact of the video service on the mobile network is increasing. In order to effectively reduce the impact of the video on the network, it is proposed to optimize the transmission of the video service through air interface multicast. [0003] In the existing multicast session establishment scheme provided, there may be multiple terminal devices receiving the same multicast service under one...
