ACCESSIBILITY MANAGEMENT METHOD AND DEVICE FOR M2M TERMINAL/TERMINAL PERIPHERAL

摘要

A reachability management method and device for a machine-to-machine/man (M2M) terminal/terminal peripheral are provided in the embodiments of the present invention, which relates to machine-to-machine/man communications. The reachability management method for the M2M terminal/terminal peripheral provided in the present invention includes the following steps: when selecting to switch to an M2M stub network, the M2M terminal/terminal peripheral sending a detach request message to a corresponding network side device, wherein the detach request message comprises a terminal signalling connection retention indication; and meanwhile, the M2M terminal/terminal peripheral sending a registration request message to an M2M gateway, wherein the registration request message contains an identifier of the network side device. A terminal, a network side device and an M2M gateway device are also provided in the embodiments of the present invention. By applying the method and device of the present invention, the network may implement effective reachability management to the M2M terminal/terminal peripheral through the M2M gateway.
