Embodiment Construction

[0022] Below in conjunction with accompanying drawing, the implementation of technical scheme is described in further detail:

[0023] The wireless telephone access system of the present invention includes two parts for completing incoming call connection and completing outgoing call connection. The process of completing an incoming call connection involves the following steps:

[0024] 1. The exchange sends a ring tone to the wireless telephone access device;

[0025] 2. The wireless telephone access device sends call messages to all base stations, and pages the corresponding mobile phones;

[0026] 3. The mobile phone is off-hook, and the response message is sent to the wireless telephone access device;

[0027] 4. Wireless telephone access device analog telephone off-hook answering switch;

[0028] 5. The wireless telephone access device completes the link connection between the switch and the mobile phone;

[0029] 6. If the caller hangs up, go to the next step; if the...

Abstract

The invention proposes a new implementation method of the wireless telephone access system, that is, the wireless telephone system adopts the access network mode and is connected with the PSTN through a standard Z interface. It solves the problems existing in the process of connecting the wireless telephone system to the PSTN through the Z interface, and at the same time provides multiple functions for the wireless user: providing the same service as the wired user under the PABX; paralleling with the wired user's phone; providing secondary dialing function; provide abnormal prompt tone function; user authentication function; wireless user data maintenance function; provide fault alarm function for BSC; and other functions. Because the present invention adopts the access mode to connect with PSTN through Z interface, compared with the prior art, it reduces the equipment complexity, reduces the cost, simplifies the software flow, and can provide multiple services.

Description

Technical field: [0001] The invention relates to a wireless telephone system, in particular to a method and a device for realizing a wireless telephone access system in the communication field. Background technique: [0002] In the current wireless telephone system, the wireless user accesses the base station through the air interface, and the base station is a part of the wireless telephone system. Through the connection of the wireless telephone system, the wireless user is connected to the public switched telephone network (PSTN), thereby receiving the PSTN call. or other wireless subscribers; it is also possible to connect one wireless subscriber to another directly within the radiotelephone system without connecting to the PSTN. [0003] In the prior art, there is a wireless telephone system using a switch architecture, which can be divided into two subsystems: a base station subsystem and a mobile switching subsystem. A base station subsystem may include a base statio...
