Femto base station measurement control method based on distributed strategy

Abstract

The invention discloses a measurement control method based on a distributed strategy for a Femto base station. The HNB periodically detects the state of its own cell and exchanges state information with the neighboring cell HNB, updates the neighboring cell information list in real time according to the state information of the neighboring cell, and sends it to the UE In the measurement object list of the HNB neighbor cell information list, only the cells with light load, little interference or no congestion are configured, and the cells with bad or poor information are not used as the measurement objects of the UE. In this way, cells with insufficient available resources, excessive interference, or congested cells are also avoided as measurement objects, which reduces the number of cells measured by the UE, reduces the measurement burden of the UE, and reduces the time overhead of the measurement process, thereby reducing the handover process. The number of attempts in the process reduces the handover delay and the call drop probability generated during the handover process, and improves the handover success rate.

Description

technical field [0001] The invention relates to the technical field of wireless mobile communication, in particular to a measurement control method based on a distributed strategy for a Femto base station. Background technique [0002] Currently, the communication technology is developing rapidly, and the third generation mobile communication system (3G) has been commercialized on a global scale. In communication networks, improving network coverage while ensuring network capacity and quality is a relatively important issue. Therefore, various forms of base stations have emerged one after another, such as macro base stations, microcell base stations, and distributed base stations. In order to strengthen the weak link of indoor coverage, a kind of Femto base station (femtocell base station, also known as home base station or Home NodeB, and later for the convenience of description, collectively referred to as HNB) has appeared. This kind of base station is characterized by sm...

AI Technical Summary

Problems solved by technology

In fact, some cells with poor information (such as cells with poor link quality) are less likely to become handover target cells. Even if they become handover target cells, call drops are prone to occur during handover

Therefore, the measurement of these cells by the UE is meaningless and time-consuming
