Embodiment Construction

[0026] see figure 1 , is a schematic diagram of the network architecture, including the user equipment (UE, which measures and forwards wireless signals) and the base station (eNB, which is responsible for signal processing and resource management), and the X2 connection between the base station and the base station (that is, the base station is connected through the X2 interface , forming a mesh network), which can directly transmit information. The user equipment transmits information through the base station, and the MME (Mobility Management Entity, mobility management entity) handles the signaling interaction between the user equipment and the core network. A base station often To access many user equipments, a base station may have multiple cells (Cell, responsible for signal processing and resource management of cells under the base station), and a sector may also have multiple cells.

Abstract

The invention relates to a base station working frequency point switching method and device. Whether a current working frequency point is interfered or not is detected by detection on whether a signal to noise ratio of the current working frequency point is larger than a preset threshold value or not. When the signal to noise ratio is not larger than the preset threshold value, the current working frequency point is interfered, and the current working frequency point needs to be switched at the moment in order to avoid influence on data transmission. Moreover, the higher the signal to noise ratio is, the higher the signal transmission quality is. When the current working frequency pint needs to be switched, a current working frequency point of a local base station is switched to a working frequency point of which the signal to noise ratio is larger than the preset threshold value and maximum in each network base station, namely, the current working frequency point is switched to a working frequency point which is free from interference and has highest signal transmission quality to avoid interference, so that the signal transmission quality is ensured.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for switching operating frequency points of a base station. Background technique [0002] With the rapid development of mobile smart terminals and the rapid increase in the number of wireless users, the demand for mobile network data is increasing day by day. In order to alleviate the contradiction between the growing wireless demand and the expensive and limited licensed spectrum, the technology of using the license-free spectrum with relatively abundant wireless resources to solve the high data volume of the mobile network came into being: that is, the LTE- U (LTE Advanced in Unlicensed Spectrums) is to deploy LTE (Long Term Evolution, Long Term Evolution) to unlicensed spectrum, use unlicensed spectrum to offload wireless services, and relieve the wireless network burden of licensed spectrum. [0003] As we all know, in the field of wireless communi...
