Abstract

The present invention discloses a method and system for shortening call establishment time delay. The method includes: A. real-time statistics of the busyness value of the traffic channel TCH of each service cell; B. when there is a user service request to access the network, analyze This user service request, judge whether this user service is the service that the network expects to shorten the time delay, if so, then go to step C, otherwise, allocate the independent dedicated control channel SDCCH for this user service request; C, judge the TCH channel of the current serving cell Whether the busyness value is less than the preset dynamic adjustment threshold, if so, then allocate the TCH channel for the user service request, otherwise, allocate the SDCCH channel for the user service request. According to the busyness of the TCH channel, the present invention can selectively allocate TCH channels for some user services whose time delay is expected to be shortened in the network to transmit signaling, and allocate SDCCH channels for other ordinary user services, so as to shorten the call establishment of corresponding user services Delay without causing beneficial effects of network congestion.

Description

technical field

[0001] The present invention relates to the technical field of communication, in particular, to a method and system for shortening the call establishment delay in the call establishment process of the GSM system (Global System for Mobile communications, namely Global System for Mobile Communications). Background technique

[0002] In the GSM system, such as figure 1 As shown, when the terminal accesses the network, it must first go through the channel initialization allocation stage, that is, the network allocates a channel for the terminal to transmit signaling.

[0003] Specifically, the network may choose to directly allocate a TCH (Traffic Channel, traffic channel) channel to the terminal, and this allocation mode is called an early allocation mode. In addition, the network can also allocate an SDCCH (Stand-alone Dedicated Control Channel, independent dedicated control channel) channel to the terminal first, and then allocate a TCH channel to the termina...
