Abstract
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.
