Abstract

In the voice or voice video businesses in a mobile comm. system, when the mobile terminal (MT) of any comm. party starts a net mutual-connecting function business (NMFB), (A) the base station controllers (BSC) of both comm. parties detect respectively the business signal of NMFB. (B) BSC of both parties and their MTs start respectively business negotiations related to NMFB. (C) BSC of both partiesbuild respectively the business channels with their net mutual-connecting function units; then via the switching procedures, lead their MTs switching to their own business channels. (D) MTs of both comm. parties exercise respectively NMFB via their own business channels. This invention also discloses the equipment and the system utilizing this method.

Description

technical field [0001] The present invention relates to a mobile communication system, in particular to a method, device and system for providing network interworking function services in the mobile communication system. Background technique [0002] An interworking function (IWF, Inter Working Function) is a service function in a wireless network, and an IWF unit serves as a function executing entity. The IWF unit is a device in the wireless network, which supports the circuit domain data service interworking function between the wireless network and other networks (such as PSTN, ISDN, Internet, etc.). The IWF unit uses synchronous and asynchronous data to perform services such as remote access, Email access, Intranet access, ISP access, public database retrieval, and interconnection of two data terminals. [0003] According to the resource location of IWF, IWF can be divided into CIWF (CDMA Inter Working Function, CDMA network interworking function) and SIWF (Share Inter ...
