Embodiment Construction

[0019] In order to save interface resources between the radio access controller (RAC) and the local exchange (LE), the method of the present invention judges whether the calling party and the called party are both locally when the RAC receives the call, and if the judgment shows that both the calling party and the called party are locally, Then, the paging message is sent directly by the RAC without switching through the local exchange (LE). The flow process of the inventive method is as figure 2 As shown, its specific implementation steps are as follows:

[0020] S1. A radio access controller (RAC) records and updates local user terminal information in real time.

[0021] In the WLL system based on CDMA2000, the user terminal has two kinds of information, IMSI and telephone number, which are used to uniquely identify the user terminal. A visitor location register database (VDB) for storing IMSI and / or telephone numbers of user terminals currently in the area covered by the...

Abstract

A method for realizing local interchange in radio local loop system includes recording and updating information of local user terminal in real time by RAC, judging whether called party is local user or not according to recorded information of user terminal when call launched by calling party is received by RAC and directly down-sending the paging message to called terminal to finalize conversation connection if it is or otherwise launching no local call through local switch.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method for realizing local switching in a wireless local loop system. Background technique [0002] Wireless local loop (WLL) refers to the use of wireless technology (including microwave, cellular communication, and cordless telephone transmission) to provide telecommunication services to mobile users in fixed user areas. In short, the wires and cables between the user's phone and the exchange are replaced by a wireless connection. Usually, the transmission system that adopts wireless technology to provide telecommunication services in the user loop section belongs to the wireless local loop (WLL). [0003] Currently commonly used WLL systems include the following: [0004] A WLL system based on Global System for Mobile Communications (GSM) or Advanced Mobile Phone Service (AMPS). [0005] WLL systems based on Personal Communications Services (PCS) or Personal Handypho...
