Method for planning capacity of multi-user mixed services in wireless network

Abstract

The invention discloses a method for planning capacity of multi-user mixed services in wireless network. The method is implemented by respectively introducing a traditional Poisson model of required voice service and a data service ON / OFF model showing service unexpectable feature; on the basis of different service models, comprehensively considering the priority level of various services and the different service quality requirements among the various services as well as the transmission feature of the wireless network system and the resource allocation and access control strategy; establishing the correspondence between wireless network performance parameters, basic parameters and unexpectable parameters of the data service, network parameters, data user number and voice service quantity by using multidimensional Markovian model so as to obtain the capacity planning of multi-user mixed services. The invention initiates completely different service models for voice service and data service, represents respective physical behavior and feature of different heterogeneous structure, and describes long range dependence unexpectable feature of the data service by using self-similarity, thus being more close to reality and satisfying plural requirements of operators.

Description

technical field [0001] The invention relates to a capacity planning method for multi-user mixed services in a wireless network, and belongs to the technical field of the optimization and planning design of the capacity of the wireless network. Background technique [0002] The service capacity planning of the wireless network is an important technical means to estimate the performance of the communication system, and it can play an important guiding role in the allocation of resources, services and the number of users in the actual network. A good capacity planning method can significantly improve the service level of the network and reduce the operating cost of the operator. [0003] Existing methods for planning network service capacity mainly include the Irish formula method for planning voice services and the Campbell method for planning mixed data services. Among them, the Irish formula method is mainly a Poisson model based on the speech service to plan the speech ser...

Problems solved by technology

[0004] However, with the development of the existing network from 2G to 3G, and the official commercialization of WCDMA, CDMA2000 and TD-SCDMA technology with my country's independent intellectual property rights, the services used by the client end are becoming more and more diverse, and different services have different transmission requirements. High-speed and massive data services will undoubtedly become the main business of the next-generation wireless network system; the previous capacity planning method based on the Poisson model of voice services will no longer be applicable
