Carrier aggregation (CA) secondary cell configuration method, base station and network system

Abstract

The invention provides a carrier aggregation (CA) secondary cell configuration method, a base station and a network system, relating to the technical field of networks, and aiming at solving the problem that the secondary cell configuration of CA may bring a huge loading pressure to networks in data hotspot areas in the prior art. The method includes the following steps: a base station establishesa connection with user equipment (UE) in a CA primary cell and receives measurement information sent by the UE, wherein the measurement information includes reference signal received power (RSRP); the base station acquires a CA preferred cell set according to the RSRP; the base station acquires the load of each CA cell in the CA preferred cell set, and removes the CA cells of which the load is greater than a load threshold to update the CA preferred cell set; and screening the CA cell with the maximum RSRP from the updated CA preferred cell set, and configuring the CA cell as a serving secondary cell of the UE. The embodiment of the invention is applied to the configuration of CA secondary cells between the UE and the base station.

Description

technical field

[0001] The present invention relates to the field of network technologies, and in particular to a carrier aggregation secondary cell configuration method and configuration device. Background technique

[0002] From a global perspective, Long Term Evolution (full name in English: Long Term Evolution, LTE for short) network traffic is ushering in explosive growth. Affected by factors such as the adjustment of tariff packages, the wide application of video services, and the accelerated development of mobile Internet services, the demand for LTE network capacity is huge. It is difficult to meet the demand for traffic growth by simply relying on the frequency loading and expansion of macro base stations. Carrier aggregation (English full name: Carrier Aggregation, referred to as: CA) has become an important means to improve mobile network capacity and user data transmission rate.

[0003] CA is a technology that increases the transmission bandwidth. It can aggreg...
