Method, apparatus, and system for switching communication path

摘要

Embodiments of the present invention provide a method, an apparatus, and a system for switching a communication path. The method for switching a communication path includes: receiving, by an access network device, a data packet for implementing a communication service between a terminal and a first media source; learning, by the access network device, according to the data packet, that a local exchange path between the terminal and the first media source is unavailable; and transferring, by the access network device, the data packet via a detour path, where the data packet is also used by a channel control device on the detour path to control the terminal to disconnect from the detour path and establish a local exchange path between the terminal and a second media source, and where the second media source is in coverage of an access network device currently providing a service for the terminal.

主权项

1. A method for switching a communication path comprising:
receiving, by a source access network device, a data packet for implementing a communication service between a terminal and a first media source; learning, by the source access network device, according to the data packet, that a local exchange path between the terminal and the first media source is unavailable; and transferring, by the source access network device, the data packet via a detour path, wherein the detour path comprises a path between the terminal and the first media source that passes through a target access network device, a channel control device, and the source access network device, wherein the data packet is used by the channel control device on the detour path to control the terminal to disconnect from the detour path and establish a local exchange path between the terminal and a second media source, wherein the second media source is in coverage of the target access network device, and wherein the target access network device is currently providing a service for the terminal.
