A wireless network voice service capacity configuration method and device

Abstract

The invention provides a wireless network voice service capacity allocation method and device. The wireless network voice service capacity allocation method includes the following steps that: the congestion rate of a voice service channel is determined according to a stochastic arrival curve and a stochastic service curve of voice service data flows; and the capacity of wireless network voice service is configured according to the congestion rate of the voice service channel. According to the wireless network voice service capacity allocation method and device of the invention adopted, mapping relationships between network capacity and system key parameters can be established based on analysis on internal links and influence between network input, network service and network output, so that network capacity allocation can be guided; and different service standards can be set for each cell, and modeling is performed according to respective user behaviors of each cell, and therefore, compared with the prior art, capacity configuration realized by the method and device of the invention is more flexible and closer to reality.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a method and device for configuring voice service capacity in a wireless network. Background technique [0002] Wireless network capacity configuration is one of the important contents of network planning and optimization. The existing commonly used wireless network voice service capacity configuration method is based on the Irish formula and the revised Irish B table formulated on the basis of it. It is an important part in the field of queuing theory. One of the theories, its two preconditions are: the arrival of users obeys the Poisson distribution and the service time of users in the system obeys the negative exponential distribution; its main measurement index is the average congestion rate. The Irish formula has played a huge role in the capacity analysis of traditional voice networks. [0003] However, the network capacity analysis based on the Irish ...

Problems solved by technology

[0003] However, the network capacity analysis based on the Irish formula has certain limitations: Usually, the Irish B table is uniformly selected and the congestion rate = 2% is used to calculate the network capacity. However, in the future fine planning and optimization work, different cells in the network may Requires different service standards, thus configuring different capacities

On the other hand, even if the traffic volume of the two cells is the same, if the user behaviors are different, the congestion rate of the cells may be different, and the correction of the Irish B table cannot solve the above two problems
