Abstract: A method for converging a call is disclosed. A non IP-Multimedia-Subsystem (IMS) network is provided with a non IMS network interworking device, by which the non IMS network is converged with a Voice over Internet Protocol (VoIP) network. The method further includes: when the non IMS network determines that a callee receiving a call request is a convergence call user, the non IMS network forwards the call request to the VoIP network; and the VoIP network initiates a call to the callee. A system for converging a call which implements the aforementioned method is further disclosed. The disclosure takes full advantage of the service characteristic of the convergence network, so as to supply users with convenient service access implementation and reduce the service charge.

Abstract: Provided is a method for a telecommunication network to provide a session service to the Internet. An access gateway of a telecommunication network supports an Internet application protocol, or an access-side device of the telecommunication network is upgraded to support the Internet application protocol, and the Internet is connected to the telecommunication network via the access gateway or the upgraded access-side device. The method further includes that an Internet user establishes a session with a telecommunication user or another Internet user via a telecommunication network. A system for a telecommunication network to provide a session service to the Internet is also provided. By upgrading an access-side device of a telecommunication network, the disclosure enables the access-side device to support an Internet application protocol and converges the Internet with the telecommunication network, thus being able to provide a session service to an Internet user.

Abstract: A method for a telecom network to provide a session service to an internet is disclosed. The internet is connected with the telecom network via an access gateway or via an access-side device which has been updated to support an internet application protocol. The method includes: an internet user establishes a session with a telecom user or another internet user through the telecom network. A system for a telecom network to provide a session service to an internet is also disclosed. In the disclosure, the access-side device of the telecom network is updated to enable the access-side device to support the internet application protocol, and the internet and the telecom network are converged, thereby providing the session service to the internet user. The disclosure facilitates the internet user to use the session service.

Abstract: It is a method for implementing terminal roam and management in the soft switch-based Next Generation Network, comprises: a user terminal moving on the IP network, when the IP address changing, the user terminal registering at a soft switch controlling device again, the user terminal attaining the allocated IP address of the said soft switch controlling device and registering at the exchange 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 judges whether the user terminal roaming, if it roaming, the soft switch controlling device further judges whether allowing the user terminal to access, if the user terminal roaming and being allowed to access, then the soft switch controlling device transmits the transmission success response to the user terminal, the user terminal accesses to the soft switch controlling device.

Abstract: The method of controlling the user calling load in Soft Switch system in present invention comprises the steps of: basic calling module receives the congestion direction message; judge whether the system congestion indicated by said congestion direction message is sporadic or sustaining; control the switching of user calling load according to the judgment whether the system congestion indicated by said congestion direction message is sporadic or sustaining. The aggressive effectiveness brought by present invention are: the system has the higher stability and reliability; when the traffic overload state occurs, the setup of maximum calling number can be guaranteed and the system can also restore to the normal load state. Soft module doesn't influence the setup of normal calling, nor does the setup of urgency special service calling; the system possesses good adaptability, the controlling of load is efficient and stable, and has the self-adapting overload controlling capability.
