Embodiment Construction

[0048] In the embodiment of the present invention, the channel quality parameter is corrected according to the correction amount that will affect the channel quality parameter, and the component carrier is selected according to the corrected channel quality parameter, so as to improve the user experience rate in the carrier aggregation environment.

[0049] In the method for managing a cell in a carrier aggregation environment in an embodiment of the present invention, as image 3 shown, including:

[0050] Step 31, the network side obtains the channel quality parameter measurement values ​​of all cells on all carriers of all base stations measured by the user equipment;

[0051] In the carrier aggregation system, the channel quality parameters of a certain cell measured by the user equipment are in one-to-one correspondence with a certain cell of a certain base station on a certain carrier, that is, a channel quality parameter uniquely corresponds to a base station, a carrier...

Abstract

The invention provides a managing method and a managing device of a region under a carrier aggregation environment. The managing method comprises the following steps that: step A. acquiring a channel quality parameter measurement value of all regions on all carriers of all base stations measured by user equipment; step B. determining correction corresponding to the channel quality parameter measurement value at least according to a carrier frequency corresponding to the channel quality parameter measurement value and utilizing the correction to correct the corresponding channel quality parameter measurement value; and the correction corresponding to the channel quality parameter measurement value is larger when the carrier frequency corresponding to the channel quality parameter measurement value is higher; and step C. selecting a maximal value from the corrected channel quality parameter measurement value and configuring the region to be a main region of the user equipment corresponding to the corrected channel quality parameter measurement value having the maximal value. Due to the adoption of the method and the device, the user experience speed under the carrier aggregation environment is improved, and load of each region can be balanced.

Description

technical field [0001] The present invention relates to a mobile communication system, in particular to a cell management method and management device in a carrier aggregation environment. Background technique [0002] As an important organization in the mobile communication field, the 3rd Generation Partnership Project (3GPP) has greatly promoted the standardization of the 3rd Generation Mobile Communication Technology (The Third Generation, 3G), and formulated a series of standards including broadband Communications including Wide Code Division Multiple Access (WCDMA), High Speed ​​Downlink Packet Access (HSDPA), High Speed ​​Uplink Packet Access (HSUPA), etc. system specification. [0003] In order to meet the challenge of broadband access technology and meet the growing demands of new services, 3GPP started the standardization of 3G Long Term Evolution (LTE) technology at the end of 2004. In June 2008, 3GPP completed the LTE-A technical requirements report and proposed...
