Problems solved by technology

[0006] But at present, it is impossible to use the modulation, demodulation and rate adaptation functions of the traditional Modem chip under the original A interface to realize the IWF function when the Ap interface is connected. Therefore, when the network is upgraded, the operator cannot make good use of the original There are network resources, resulting in a waste of network resources

Abstract

The invention provides a method of realizing IWF function of an AP interface, which is applied in communication field. The invention has the technical proposal that: a mobile terminal launches the circuit data business under an Ap port, MSCe, i.e. mobile switching simulation is coordinated with MGW, i.e. media gateway and inserts TC, i.e. vocoder resource in calling connection. TC completes the conversion between TDM, i.e. time division multiplexing and an IP port, in order to realize the network intercommunication under the Ap port. The invention can multiplex the resource under the prior Ap port and reduce changes to design.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for realizing the network intercommunication function of an AP interface. Background technique [0002] The CDMA mobile network implements the traditional circuit-type data service between the PSTN network and the PSTN network through the IWF (Inter-working Function), that is, the network interworking function device. IWF is a device that provides interworking functions between CDMA and PSTN networks. It utilizes the MODEM on the mobile station MS and the IWF, that is, the modem, to provide users with the same function as the wired MODEM to realize circuit data services. [0003] The traditional CDMA 2G core network is connected to the BSC through the A interface. When the MS mobile user initiates a circuit data service, the core network passes the user data accessed from the A interface circuit through the modulation and demodulation and rate adaptation of the Modem chip. It...
