METHOD, DEVICE, AND SYSTEM FOR SYNCHRONIZING TERMINAL STATE IN GENERIC ACCESS NETWORK
First Claim
1. A method for synchronizing terminal state in a Generic Access Network, GAN, comprising:
- receiving, by a network device of the GAN, Circuit-Switched, CS, domain state information and Packet-Switched, PS, domain state information reported by a terminal; and
updating, by the network device, state information of the terminal according to the received CS domain state information and PS domain state information.

Abstract
The present invention relates to wireless communication, and discloses a method, a device, and a system for synchronizing a terminal state in a GAN to ensure that the GAN can know the relevant state context information of the terminal correctly. In the present invention, a network device of the GAN receives CS domain and/or PS domain state information reported by a terminal; and the network device processes the terminal registration information according to the received CS domain and/or PS domain state information. After the connection is reestablished between the terminal and the GAN, the terminal reports the CS domain and/or PS domain state information in the GAN mode to the GANC. The terminal may report the CS domain and/or PS domain state information in the GERAN/UTRAN mode to the GANC in the registration process. The terminal may also initiate a registration update process after the CS domain and/or PS domain state in the GERAN/UTRAN mode changes.
