Description

Method and device for enhancing mobility performance

technical field

The present invention relates to the field of communication technology, in particular to a method and device for enhancing mobility performance.

Background technique

The design and working process of the switching algorithm in the current network are implemented as follows:

First, design the workflow of the algorithm in the product development stage, and then determine the relevant parameters used in the algorithm through simulation, including hysteresis (hysteresis, Hys), trigger time (Time to Trigger, TTT), etc. In the simulation process, it is usually the channel model specified in the standard, for example, the urban macro base station model (Urban Macro, UMa), the suburban macro base station model (Suburban Macro, SMa), the rural macro base station model (Rural Macro, RMa), etc. However, in a real network, even in one coverage area, there will be multiple channel models; and, because the signal passes from the transmitter of the base station to the receiver of the terminal is not completely different, the channel fading of each channel will be different. . This is because channel fading is related to many factors such as space loss, shadow, and user mobile fading. Therefore, the parameters provided by the static simulation at the design stage are rough, because these parameters cannot be well matched with the actual environment.

In order to solve the problem that the parameters used in the algorithm cannot match the actual environment, the current general solution is to adjust these parameters through on-site measurement during the on-site network deployment stage, and then formally operate. However, in the formal operation process, the channel will also change due to the demolition and construction of buildings, felling and planting of trees, etc., or, some micro base stations, or pico base stations are added in the original macro base station coverage area. base station. In this way, both the initial channel environment and the interference environment have changed, so that the adjusted parameters cannot match the environment, thereby deteriorating the handover performance.
