Problems solved by technology

This method of using digital signaling to send and receive the called number can save resources, but the method of sending the number one by one will increase the burden on the signaling link in the case of heavy traffic, and at the same time, the AN side and LE The processing capacity of the side also puts forward higher requirements
[0007] When the wireless local loop system is used as the access side, under normal circumstances, the mobile terminal will send the called number to the wireless system at one time, but the above two methods of sending the called number used by the current V5 interface do not support The transmission of multiple numbers, but also has the above-mentioned various defects

Embodiment Construction

[0043] According to the V5.1 standard, the call process of sending the called number in DTMF mode is as follows: figure 1 As shown, the DTMF information in the figure is transparent through the V5 interface.

[0044] The present invention uses the extended Establish message to carry the called number to the LE side at one time. figure 2 shown, including the following steps:

[0045] Step 101, the mobile terminal MS starts calling, and sends a calling message, and the called number is carried in the message;

[0046] Step 102, the AN side of the V5 interface sends the establishment message Establish, and carries the called number to the LE side through the extended field of the Establish message;

[0047] Step 103, the LE side responds to the Establish message, and sends an establishment confirmation message EstablishAck to the AN side;

[0048] Step 104, the LE side plays the ring back tone to the mobile terminal.

[0049] In step 102, the structure of the establishment mes...

Abstract

The invention relates to a method for sending called number in a wireless local loop system V5 interface, comprising that a mobile terminal starts calling and sends calling messages to a V5 interface The invention relates to a method for sending called number in a wireless local loop system V5 interface, comprising that a mobile terminal starts calling and sends calling messages to a V5 interfaceaccess line side and the V5 interface access line side carries the called number to a local exchanger side by establishing the extended field of a message or the extended field of a signal message. Thaccess line side and the V5 interface access line side carries the called number to a local exchanger side by establishing the extended field of a message or the extended field of a signal message. The method saves the receiving and sending of number equipment resource, saves the running cost, can carry a plurality of called numbers at one time and shortens the connecting delaying.e method saves the receiving and sending of number equipment resource, saves the running cost, can carry a plurality of called numbers at one time and shortens the connecting delaying.

Description

technical field [0001] The invention relates to the field of wireless local loop systems, in particular to a method for sending a called number in a V5 interface of a wireless local loop system. Background technique [0002] The V5 interface protocol is the technical specification for the interface between the local exchange Local Exchange (LE for short) and the access network AccessNetwork (AN for short). [0003] In recent years, with the rapid development of wireless communication systems, more and more operators use the wireless system as the access side, and connect mobile terminals to the local switching network through the V5 interface, which is the so-called wireless local loop Wirless Local Loop, referred to as WLL system. According to different access network sides, common WLL systems include Global Systems for Mobilecommutations, referred to as GSM WLL system, Code Division Multiple Access Code Division MultiPleAccess, referred to as CDMA WLL system, and Personal...
