Method and device for optimizing system capacity dynamically

Abstract

The invention relates to a method and a device for optimizing system capacity dynamically. The method comprises the following steps of: acquiring cell traffic; and adjusting system capacity parameters according to the acquired cell traffic. The device comprises an acquisition unit for acquiring the cell traffic and an adjustment unit for adjusting the system capacity parameters according to the traffic acquired by the acquisition unit. By adopting the method and the device of the invention, the cell traffic is acquired by the statistics of various parameters, and the system capacity parameters are adjusted dynamically according to the cell traffic to perform tradeoff on user capacity and service quality so as to optimize the system capacity; and thus, the requirements of different scenes on the peak period and low-ebb period of a cell or hotspot or non-hotspot cells are met, resources are fully utilized and errors caused by configuration threshold are reduced.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and in particular, to a method and apparatus for dynamically optimizing system capacity. Background technique [0002] With the development of mobile communication technology, in the next generation wireless communication system, especially the E-UTRA (Evolved-UMTS Terrestrial Radio Access, Evolved Universal Mobile Telecommunications System Terrestrial Radio Access) system, by introducing a network self-organization mechanism to Reduce manual participation in network planning, operation and maintenance, and reduce network construction and operation costs. The most important feature of SON (Self-Organization Network) technology is the optimization of system capacity, which mainly involves parameters that affect system capacity, including admission threshold, load congestion threshold, and QoS (Quality of Service); Based on the aforementioned parameters, several methods for ...

[0019] However, the admission control method used in the current wireless communication system directly limits the upper limit of the bearer that can be accessed by the cell, but cannot dynamically adjust the upper limit of admission according to the dynamically changing traffic load or the long-term traffic load of different cells, and the system capacity cannot be fully reached. optimization; at the same time, load congestion control also determines the upper limit of the cell's access to the bearer, but the strict load congestion threshold will cause waste of resources, and there is no way to dynamically adjust the threshold; in addition, the QoS that affects the system capacity It is not a scientific and unchangeable fixed value, which can fluctuate within a reasonable range or magnitude for different scenarios, but in existing wireless communication systems, QoS is usually stipulated by standards or configured by operators, often due to the use of fixed values. No flexible adjustment mechanism
