System and method for optimizing wireless network topology structure

Abstract

The invention discloses a method for optimizing a wireless network topology structure. The method comprises the following steps of: acquiring the number of switching times of a wireless terminal between wireless receiving equipment and wireless transmitting equipment, and multiplying the number of switching times by a signaling overhead coefficient to obtain a migration amount between the wireless receiving equipment and the wireless transmitting equipment; establishing corresponding points of the wireless receiving equipment and the wireless transmitting equipment; dividing the corresponding points into groups the number of which is the same as that of lower-layer control units; calculating the sum of network capacity parameters of corresponding points of each group and the sum of migration amounts of adjacent corresponding points of different groups in each dividing mode; and when the sum of the network capacity parameters is the most average and the sum of the migration amounts is the minimum, determining the dividing mode to be optimal. The invention also discloses a system for optimizing the wireless network topology structure. According to the method and the system, the signaling overhead brought by switching of the wireless terminal between the wireless receiving equipment and the wireless transmitting equipment is acquired, and the wireless receiving equipment and the wireless transmitting equipment are combined with the capacities of control units on each layer to optimize the wireless network topology structure, thereby improving the network quality at a macro level.

Description

technical field [0001] The invention relates to a network optimization system, in particular to a wireless network topology optimization system and method. Background technique [0002] With the rapid development of mobile communication, the number of communication service items continues to increase, and the number of wireless terminal users such as mobile phones and netbooks is also increasing. In order to expand competitive advantages and control costs at the same time, rational use of existing network resources has become the primary task of major operators. . At present, the wireless communication network has multiple coverage cells, and the users in each coverage cell realize wireless communication by exchanging data with the corresponding wireless receiving / transmitting equipment, and the wireless receiving / transmitting equipment can be a base station in the GSM network (BTS), Node B in the WCDMA network, etc., generally, the range covered by the multiple wireless re...

Problems solved by technology

[0004] At present, operators mainly divide adjacent coverage cells in a certain region or administrative range into the same area according to the geographic location or administrative area of ​​the coverage cell or according to experience, and the coverage cells in this area perform data processing via the same lower-level control unit. For switching control, the adjustment of the wireless network topology only relies on the test of the covered cells to make local adjustments, or only when individual users generate complaints, local adjustments are made for this user, which does not play a fundamental role in improving the overall network quality Therefore, the existing wireless network topology often cannot effectively use network resources, resulting in a decrease in network carrying capacity, and a decrease in the quality of the network perceived by users. Sometimes it has to be improved by increasing network capacity, which increases the cost.
