Abstract

The invention provides a method for continuous call and a control device. The invention provides a method for continuous call and a control device aiming at the not timing and inconvenient problem of emergency continuous call in the current technology. The invention judges whether the emergency calling terminal is the high priority terminal; while the judging result is the high priority terminal, noticing the high priority terminal needing the called terminal number and connecting the emergency calling to the corresponding terminal of the called number to achieve the prior connection for the high priority terminal; under the special situation of the high priority terminal, if the current call quantity is too large to assure all the calling connection, the calling of the high priority terminal of the high priority terminal can be connected preferably and timely.

Description

technical field

[0001] The present invention relates to the field of mobile communication, in particular to a method and control equipment for connecting calls. 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 process, the BSC rec...

Embodiment Construction

[0019] refer to figure 1 , figure 1 It is a schematic flowchart of a method for connecting a call according to an embodiment of the present invention, including:

[0020] Step 102: According to the received emergency call, determine whether the terminal corresponding to the emergency call calling party is a high-priority terminal, and the high-priority terminal is a terminal that has priority information and needs to be connected first;

[0021] In a specific implementation, the emergency call may be an emergency call such as 112 or 911. Since a call initiated through 112 or 911 will be identified as an emergency call in the channel request message, the access device such as the BSC receives this When there is a call of this type, the call can be answered with priority. The priority connection may mean that in a specific situation, when there are too many calls to be connected that cannot satisfy the current call, resources of ordinary calls may be preempted, and the calls m...
