US 2024/0188104 A1 · COMMUNICATION METHOD AND APPARATUS

Abstract

A communication method includes: obtaining first information from a first core network device, where the first information is used to request to add a first terminal device to a multicast service session corresponding to a first multicast service; and adding the first terminal device to a multicast service session corresponding to a second multicast service when a first condition is met, where the first condition includes that the first multicast service and the second multicast service are a same multicast service, and the second multicast service is provided by a second core network device. The first terminal device is added to the multicast service session corresponding to the second multicast service, so that service data of the second multicast service can be simultaneously provided for terminal devices in two networks by using an established resource related to the second multicast service.

Dependent claims

A method, applied to an access network device, the method comprising:

obtaining first information from a first core network device, wherein the first information is used to request to add a first terminal device to a multicast service session corresponding to a first multicast service;
and
adding the first terminal device to a multicast service session corresponding to a second multicast service when a first condition is met, wherein the first condition comprises that the first multicast service and the second multicast service are a same multicast service, and the second multicast service is provided by a second core network device.

A method, applied to a first core network device, the method comprising:

sending first information to an access network device, wherein the first information is used to request to add a first terminal device to a multicast service session corresponding to a first multicast service;
and
receiving second information or third information from the access network device when the first terminal device joins a multicast service session corresponding to a second multicast service, wherein
the first multicast service and the second multicast service are a same multicast service, and the second multicast service is provided by a second core network device;
the second information indicates not to establish a first data transmission channel with the first core network device, and the first data transmission channel is used to transmit service data of the first multicast service;
and the third information indicates that the first data transmission channel established with the first core network device is in an inactive state, and the first data transmission channel is used to transmit the service data of the first multicast service.
