Embodiment Construction

[0030] The technical scheme of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific examples, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention .

[0031] Such as figure 2 As shown, a method for shortening the call setup delay provided by the embodiment of the present invention includes the following specific steps:

[0032] S10, real-time statistics of the busyness value of the traffic channel TCH of each serving cell;

[0033] S20. When there is a user service request to access the network, analyze the user service request to determine whether the user service is a service that the network expects to shorten the delay. Control channel SDCCH;

[0034] S30. Determine whether the busyness value of the TCH channel of the current serving cell is less than a preset dynamic adjustment threshold,...

Abstract

The invention discloses a method and a system for shortening call establishment time delay. The method comprises the following steps: A, doing statistical analysis on the busy degree values of traffic channels TCH of service cells in real time; B, when a user service requests to access a network, analyzing the user service request and judging whether the user service is a service of which the time delay is expected by the network to be shortened, returning to step C if the user service is a service of which the time delay is expected by the network to be shortened, and allocating a stand-alone dedicated control channel SDCCH for the user service request; and C, judging whether the busy degree value of the TCH of the current service cell is smaller than a preset dynamic adjustment threshold, allocating a TCH for the user service request if the busy degree value of the TCH of the current service cell is smaller than the preset dynamic adjustment threshold, or allocating a SDCCH for the user service request. According to the method and the system, TCHs can be selectively allocated for some user services, of which the time delay is expected by the network to be shortened, according to the busy degrees of the TCHs to transmit signaling, and SDCCHs can be allocated for other common user services. Therefore, call establishment time delay of a corresponding user service is shortened without causing network congestion.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular, to a method and system for shortening the call establishment delay during 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 te...
