Cell reselection parameter configuration method and base station

Abstract

The embodiment of the invention discloses a cell reselection parameter configuration method and a base station, which are used to realize the self-configuration of cell reselection parameters and improve cell network performance. The method in the embodiment of the present invention includes: the base station monitors the neighboring cells of the cell, and then obtains the system information of the detected neighboring cells, and reselects the neighbor cell with the highest priority among the detected neighboring cells according to the system information It is determined as the self-configuration reference neighboring cell, and the cell reselection parameters of the current cell are self-configured according to the cell reselection parameters of the self-configuration reference neighboring cell.

Description

technical field [0001] The present invention relates to the communication field, in particular to a cell reselection parameter configuration method and a base station. Background technique [0002] In a wireless communication system, in order to enable the signal to cover the entire geographical area, it is usually necessary to plan and design the area reasonably and meticulously according to the deployment of the macro base station, so that the base station can provide mobile terminals with relatively Even so, due to the unique channel characteristics of the indoor wireless environment, the indoor signal has weak coverage. In order to solve the indoor coverage problem, the industry proposes a micro base station, which is indirectly connected (such as through a digital subscriber line (DSL, Digital Subscriber Line) ) router or modem) or directly connected to the Internet and mobile operator network, unlike macro base stations, micro base stations are generally deployed in us...

Problems solved by technology

When the static configuration method is adopted, the following problems are encountered: 1. When there is a room distribution signal or a strong macro network signal (but there is weak coverage or no dominant coverage in some areas of the house), it is difficult for the micro base station to absorb traffic; 2. , Different parameters have inconsistent influence ranges, such as in Global System of Mobile Communication (GSM, Global System of Mobile communication), cell reselection offset (CRO, Cell Reselect Offset), Rxlev_Access_Min (that is, the cell allows mobile stations (MS, Mobile Station) Parameters such as the minimum receiving level for access) affect the cell reselection boundaries of all neighboring cells, while parameters such as cell reselection hysteresis (CRH, Cell Reselection Hysteresis) only affect the cell reselection boundaries of neighboring cells with different LAC configurations from the micro base station , when only CRO and Rxlev_Access_Min are adjusted, although the micro base station absorbs the traffic of the macro base station, it is easy to absorb the traffic of the adjacent micro base station, which does not meet the home deployment requirements of the micro base station; when only the CRH parameters are adjusted, it only affects The cell reselection boundary of the neighboring cell with different LAC configuration from the micro base station, and the cell reselection boundary of the neighboring cell with the same LAC configuration as the micro base station still faces the problem of static configuration

[0004] Currently known cell reselection parameter configurations are mainly based on drive test configurations or configurations using typical values. The limitations of this method are: on the one hand, the number of cells in the actual network is large, and the wireless environment varies greatly, making it difficult to model typical scenarios. At the same time, using this method will cause a lot of manpower and material resources; on the other hand, this method is limited by manual experience, and the individual differences are large, which may easily lead to unreasonable parameter configuration, resulting in untimely reselection or ping-pong re-selection. Election problems, which lead to poor network performance in the community
