<p>A method for implementing terminal roam and roam management in the soft switch-based Next Generation Network, comprises: a user terminal moving on the IP network, when its IP address changing, the user terminal registering at a soft switch controlling device again, the user terminal attaining an allocated IP address of the said soft switch controlling device and registering at the soft switch controlling device; after the soft switch controlling device receiving the register request of the user terminal, it attaining the user data of the said terminal from a database; the soft switch controlling device judging whether the user terminal is roaming, if it is roaming, the soft switch controlling device further judging whether to allow the user terminal to access; if the user terminal roaming and being allowed to access, then the soft switch controlling device transmitting a register success response to the user terminal, the user terminal accessing to the soft switch controlling device successfully. This method can provide the function of terminal roam in the NGN, and implementing the roam management for the terminal, including a roam right management function, a roam identification function and a roam charge function for the user.</p> |
