Abstract

A cell reselection method and device, the method comprising: for any cell, acquiring traffic information of each user terminal in the cell; determining traffic of each user terminal according to the acquired traffic information of each user terminal Activeness: when it is determined that the network load of the cell is greater than the set first threshold, redirecting the user terminal whose activity is not less than the set second threshold to a network load not greater than the set first threshold other districts. In the technical solution of the present invention, since the load information on the network side and the traffic information on the user terminal side are comprehensively considered when performing cell reselection in a heterogeneous network scenario, blind selection of users to be redirected is avoided. The problem of network load fluctuations caused by terminals achieves the purpose of dynamically adjusting the load status of different networks, reducing network congestion, and realizing coordinated utilization of resources, and improves the effect and execution efficiency of cell reselection.

Description

Technical field [0001] The present invention relates to the field of wireless communication technology, and in particular to a method and equipment for cell reselection. Background technique [0002] In heterogeneous wireless network environments including LTE (Long Term Evolution), UMTS (Universal Mobile Telecommunications System), GSM (Global System for Mobile Communication, global mobile communication network) and other network types, often used The cell reselection method is based on the measured RSRP (Reference Signal Receive Power) for cell camping selection, such as triggering cell reselection based on the RSRP threshold measured by the user terminal and selecting the best RSRP signal quality The cell is camped. [0003] However, when the above method is used for cell reselection, because usually only the RSRP information on the user terminal side is involved, and the load information on the network side cannot be obtained, it may cause a large number of idle user terminals...
