Problems solved by technology
[0003] In the previous generations of mobile communication technologies, such as the 3rd generation (3G) mobile communication technology and the 4th generation (4G) mobile communication technology, the promotion of multicast / broadcast solutions has encountered great difficulties. Difficulties
Specifically, the multicast / broadcast solution in the previous generations of mobile communication technologies needs to add dedicated network elements and interfaces that support multicast / broadcast on the basis of the existing communication architecture, and also requires dedicated multicast / broadcast channel support , which not only increases the overhead of the operator, but also increases the complexity of the terminal

The embodiment of the invention provides a multicast / broadcast service communication method, device, relates to the field of communication, and can save network resource overhead. The method comprises the following steps: terminal equipment determines a first multicast / broadcast service, wherein the first multicast / broadcast service is a multicast / broadcast service to be quitted by the terminal equipment; and the terminal equipment sends a first message, wherein the first message carries the recognition information of the first multicast / broadcast service. The embodiment of the invention is applied to mobile communication systems such as 5G and the like.
Description
technical field [0001] The present application relates to the communication field, and in particular to a communication method and device for multicast / broadcast services. Background technique [0002] With the development of mobile Internet, mobile high-definition video services are showing a blowout trend. Users are gradually changing from watching popular programs through fixed TVs to watching popular programs through mobile phones and other terminals based on the mobile Internet. Therefore, the impact of video services on the mobile Internet is becoming more and more intense. The transmission of video services will greatly reduce the impact of video traffic on mobile networks. [0003] In the previous generations of mobile communication technologies, such as the 3rd generation (3G) mobile communication technology and the 4th generation (4G) mobile communication technology, the promotion of multicast / broadcast solutions has encountered great difficulties. Difficulties. ...
