Problems solved by technology

Because the statistical indicators are adjusted when the SDCCH channel is found to be congested, and whether the adjusted channel structure is reasonable cannot be evaluated, or the SDCCH channel configuration itself has redundancy, but since there is no congestion, the channel structure is not adjusted. In this way, it is easy to cause unreasonable channel configuration and waste of resources

Embodiment

[0101] Take an urban area as an example:

[0102] From April 6th to 12th, the average location update times during busy hours in this urban area was 431,935 times, the number of call establishment times was 359,016 times, the number of SMS establishment times was 88,360 times, the number of shutdowns was 6953 times, and the number of times occupied by other reasons was 52,836 times. In this way, the actual traffic volume of SDCCH is calculated as:

[0103] SDCCH_TRAFFIC=(number of location updates×3.5+number of call establishment×2.8+number of short messages×6.2+number of shutdowns×2.9+other reasons×0.9) / 3600

[0104] =(431935×3.5+359016×2.8+88360×6.2+6953×2.9+52836×0.9) / 3600

[0105] = 870.15 Ireland

[0106] The average traffic of TCH is:

[0107] TCH_TRAFFIC=6901 Ireland

[0108] The number of users is: LAC_SUB=290373.

[0109] It can be calculated that the traffic model of the urban area is:

[0110] The traffic volume of TCH per user is: T_TRAFFIC_SUB=23.77mERL.

[0111] The SDCCH traf...

Abstract

The invention discloses a standalone dedicated control channel (SDCCH) configuration method, and belongs to the field of channel configuration in mobile communication. The method comprises the following steps of: calculating traffic of SDCCHs and traffic of traffic channels (TCHs) according to acquired related traffic statistical data of a link access control / base station control (LAC / BSC) level in a global system for mobile communication (GSM) network; calculating the available quantity of the TCHs in a cell according to the carrier frequency configuration of the cell; and determining an SDCCH configuration scheme of the cell according to the available quantity of the TCHs in the cell and a ratio of the traffic of the TCHs to the traffic of the SDCCHs. By the method, only the related traffic statistical data of the LAC / BSC level is required to be acquired, the channel configuration of the cell in a region can be reasonably evaluated without the influence of regions and other factors, and a channel ratio can be dynamically regulated, so the traffic can be balanced, and the aim of optimum resource configuration can be fulfilled.

Description

Technical field [0001] The present invention relates to the field of channel configuration in mobile communication, in particular to a real-time effective SDCCH channel configuration method. Background technique [0002] On the air interface of the mobile communication GSM network, a large amount of information needs to be transmitted. According to different types of channel bearer services, different logical channels are defined. The logical channel is mapped on the physical channel. GSM system logical channels are divided into two categories: dedicated channels and common channels. Dedicated channels mainly refer to business channels used to transmit user voice or data, and also include some dedicated control channels for control. Among all logical channels, the SDCCH channel (Independent Dedicated Control Channel) plays a very important role. Its main role is to undertake the transmission of system information before assigning the TCH channel, such as user access, user regis...
