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

PROBLEM TO BE SOLVED: To provide a managing method and a managing device for a cell in a carrier aggregation environment. SOLUTION: The managing method includes: a step A for acquiring channel quality parameter measurement values in whole cells on whole carriers of whole base stations, which are measured by a user facility; a step B for specifying a correction amount corresponding to the channel quality parameter measurement value based on a carrier frequency corresponding to at least the channel quality parameter measurement value, and correcting the corresponding channel quality parameter measurement value by using the correction amount; and a step C for selecting a maximum value from the channel quality parameter measurement value after correction since the correction amount corresponding to the channel quality parameter measurement value becomes larger as the carrier frequency corresponding to the channel quality parameter measurement value is higher and for arranging the cell corresponding to the channel quality parameter measurement value after correction, which has the maximum value, in a primary cell of the user facility.

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 field of mobile communication, the 3rd Generation Partnership Project (3rdGeneration Partnership Project, 3GPP) has greatly promoted the standardization of the third generation mobile communication technology (TheThirdGeneration, 3G), and formulated a series of Communication system specifications including Wide Code Division Multiple Access (WCDMA), High Speed ​​Downlink Packet Access (HSDPA), High Speed ​​Uplink Packet Access (HSUPA), etc. [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 (Long Term Evolution, LTE) technology at the end of 2004. In June 2008, 3GPP completed the LTE-A technical requi...
