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 an SDCCH channel configuration method, which belongs to the field of channel configuration in mobile communications. This method calculates the SDCCH traffic volume and TCH traffic volume based on the obtained LAC / BSC level related traffic statistics data in the GSM mobile communication network, and calculates the number of available traffic channels in the cell based on the carrier frequency configuration of the cell. , and then confirm the SDCCH channel configuration plan of the cell based on the number of available traffic channels of the cell and the ratio of TCH traffic volume to SDCCH traffic volume. Through this method, only relevant traffic statistics data at the LAC / BSC level can be obtained, and the regional cell channel configuration can be reasonably evaluated without being affected by geographical and other factors, and the channel ratio can be dynamically adjusted to achieve a balanced traffic volume. To achieve the purpose of optimal resource allocation.

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...
