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 connection of a called terminal. Background technique [0002] In the Global System for Mobile communications (GSM, Global System for Mobile communications), whether a terminal (such as a mobile phone or other device) is a calling or a 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 Station Controller) determines 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 this idle sdcch, so that the terminal sends related service call messages on the idle sdcch. If in the subsequent connection process, the BSC ...

Problems solved by technology

[0004] The inventor found in the research process of the prior art that when the high-priority terminal is called, the BSC can only judge whether the terminal is a high-priority terminal by carrying the priority information in the channel request message of the called terminal. The program of the terminal needs to be modified to make the channel request message of the terminal carry the priority information. As a result, such a solution cannot be applied to the existing terminal, and it cannot achieve the purpose of priority connection when the high-priority terminal is called.
