Abstract: Disclosed are a method and apparatus for switching a service of a multi-mode terminal. The method includes: a multi-mode terminal performing, via one activated Packet Data Protocol (PDP) link, data transmission for a Packet Switch (PS) service requested by a user; when detecting an available network in a current network environment, the multi-mode terminal activating a PDP link corresponding to the detected available network; and the multi-mode terminal performing data transmission for the PS service via one or more PDP links in activated PDP links. Through the technical solution, the problem that a multi-mode terminal cannot implement high speed data transmission for a PS service by using network resources of multiple communication networks is solved, and the effect of multi-network binding high speed data transmission for a PS service is achieved.
