A method and device for gsm/gprs future network carrier frequency resource estimation

Abstract

The present invention relates to a method and device for estimating carrier frequency resources of a GSM / GPRS future network. The method includes: step 1, estimating the required number of carrier frequency resources C1 according to the demand for voice traffic of the GSM / GPRS future network in the target period; The number of dynamic physical dedicated channels CH dynamic PDCH is then converted into the number of carrier frequency resources C2=CH dynamic PDCH / 8; Step 3, calculate the number of carrier frequency resources C required by the GSM / GPRS future network in the target period, C=C1+C2. The invention considers the voice traffic and the data traffic separately, establishes the relationship between the voice traffic and the voice carrier frequency resource demand and the data traffic volume and the data carrier frequency resource demand, and clearly and intuitively reflects the size of the traffic and the carrier frequency. The logical relationship of scale requirements; solves the problem that the estimated scale of the future network depends too much on the selection of a certain parameter, and reduces the possibility of large deviations in the estimation of the network scale.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method and device for estimating carrier frequency resources of the GSM / GPRS future network. Background technique [0002] In the planning stage of mobile communication wireless networks, operators need to estimate the total resource allocation requirements of the network during the planning period based on the communication capacity requirements of future network users from the perspective of the entire network, so as to guide future network expansion construction. In the GSM / GPRS wireless network, the most important resource is the carrier frequency resource, so network scale estimation is to estimate the carrier frequency resource allocation requirements of the future network in the target period. In the GSM wireless network, user services are mainly voice services. The expansion scale estimation of the wireless network is usually based on the Irish B table to determine t...

Problems solved by technology

[0008] 1) It fails to clearly reflect the logical relationship between the user data service volume and the carrier frequency resources configured by the network to carry the data service. The parameter of the data service channel reservation ratio is not intuitive enough, but only indirectly reflects the capacity demand of the data service;

[0009] 2) There is a large uncertainty in the determination of the data service channel reservation ratio parameter, which is usually determined by subjective and artificial corrections by project planners on the basis of analyzing the current network conditions, and there is no objective and quantitative determination basis, there is greater roughness and randomness;

[0010] 3) The estimated scale of the network is directly related to the reserved proportion parameter of the data service channel, and the two have the same degree of deviation. Therefore, the reserved proportion parameter of the data service channel with greater uncertainty increases the degree of deviation of the estimated scale of the network
