Method, system and equipment for implementing called terminal succeed

Abstract

The invention discloses a method, a system and a device for connecting high-priority users. The invention is designed aiming at the situation that when signal channel resources in the prior art can not meet the connection of a current called terminal, priority information is configured in a first message which is issued from a control device of a core network to the called terminal, thus leading an access device which is pertained by the called terminal to be capable of obtaining the priority information of the called terminal and carrying out the treatment according to the priority information of the called terminal, that is, the signal channel resources of the normal terminals are occupied to be used by the high-priority terminals, and the connection demands on the high-priority terminals are met, thus ensuring the timely access of the high-priority terminals which are called under the situation of ensuring no change of the terminal procedure.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a method, system and equipment for realizing called terminal connection. Background technique [0002] In the Global System for Mobile communications (GSM, Global System for Mobile communications), regardless of whether the terminal (such as a mobile phone and other devices) is the calling or the called, when accessing the network, the first message when accessing the communication network is channel request message, after receiving the message, the base station controller (BSC, Base StationController) judges whether there is an idle signaling channel (sdcch, StandaloneDedicated Control CHannel); if there is an idle signaling channel, the BSC will issue an immediate assignment The message is sent to the terminal, so that the terminal migrates to the idle sdcch, and the terminal sends the relevant service call message on the idle sdcch. If in the subsequent connection ...

AI Technical Summary

Problems solved by technology

[0004] During the research of the prior art, the inventor found that when the high priority terminal is called, the BSC can only pass the channel request message of the called terminal Carry priority information to determine whether the terminal is a high-priority terminal. Such a solution needs to modify the program of the terminal to make the terminal channel request message carry priority information. As a result, such a solution cannot be applied to existing terminals, and cannot To achieve the purpose of priority connection when high-priority terminals are called
