Problems solved by technology

The operation of 3G brings new bandwidth and high frequency utilization, and also brings new problems to the adjustment of 2G data service bearing platform
However, if the different bandwidth requirements of users are considered, the Erlang C method is not completely suitable for WCDMA cell capacity calculation
In addition, because the Erlang C method is used to calculate data service resources in the prior art, services with different data rates are calculated separately, so the channel cannot be fully utilized, resulting in low relay efficiency

Embodiment Construction

[0121] For virtual hybrid business, some companies have given a Campbell-based approach. This method comprehensively considers all services and constructs an equivalent service, and calculates the total traffic volume that the system can provide the equivalent service based on this, and then obtains the capacity calculation of the mixed service. The method finally uses Erlang B to calculate the corresponding channel number. At present, it is more inclined to use this method to calculate the virtual hybrid service in the CS domain at home and abroad.

[0122] The algorithm of the present invention is to uniformly calculate the services of different rates, so that the channel reuse rate of the base station is high, and it overcomes the shortcomings of the prior art that the system capacity cannot be fully utilized and the relay efficiency is low. The budget is moderate.

[0123] Below, before presenting the method of using virtual hybrid services to calculate the channel budget of t...

Abstract

Said invention refers to wireless resource occupying algorithm of data grouping service. It contains selecting one service from data grouping service as basic service, calculating each service relatively wireless resource intensity, based on based on selected basic service utilizing each service resource intensity doing weighted average to each service volume, mixing to one virtual mixed service, to obtain virtual mixed service total amount, then utilizing Erlang C method to satisfy certain of QoS required virtual channel number, and then to obtain grouped data service required occupied channel number. Utilizing similar method, said invention can obtain occupied channel number for satisfying certain of blocking rate circuit switching service required. Thereby, it can proceed evaluation to wireless communication systematical wireless resource occupied status including circuit switching domain and grouping exchange domain. Said invention has advantages of leading-in virtual mixed service total amount, thereby in consideration of data grouping service delay and retransmission.

Description

Technical field [0001] The present invention relates to the field of wireless communication systems, and in particular to algorithms for the occupation of wireless resources by various services in the wireless communication system. Background technique [0002] In the wireless communication system network planning, the analysis of wireless resource occupation is an important prerequisite for the entire network planning. Up to now, we only have a clearer understanding of the behavior of voice services in the network, but little is known about the demand for network resources of data services and the behavior of data services in mobile networks. In this case, we need to specifically analyze the occupation of wireless resources by different services in the wireless communication network, and accurately understand the switching and base station system capacity, which will play a fundamental guiding role in the rational network structure design and network deployment in the future. ...
