Embodiment Construction

[0041] The following will clearly and completely describe the technical solution in this embodiment with reference to the drawings in this embodiment. Obviously, the described embodiment is only a part of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0042] An embodiment of the present invention provides a method for managing a secondary cell. The execution subject of the method is the base station where the primary cell accessed by the user equipment is located. The method is mainly applied in the configuration process of the secondary cell, such as figure 1 As shown, specifically:

[0043] 101: Receive a first report message sent by the user equipment, the first report message carries the cell identifier of the first cell, and the first report message is...

Abstract

The invention discloses a method and a device for managing a secondary serving cell, which relates to the technical field of communication, and is provided for solving a problem of high signaling overhead existing in the prior art brought about frequency configuration and de-configuration of the secondary serving cell. The method comprises the steps of receiving a first report message which is sent by user equipment and carries a cell identifier of a first cell; searching a frequently changing cell identifier list according to the cell identifier of the first cell, and determining whether the frequently changing cell identifier list contains the cell identifier of the first cell or not; starting timing if the frequently changing cell identifier list contains the cell identifier of the first cell; and forbidding to configure the first cell to be a secondary serving cell of the user equipment and configuring a second cell to be the secondary serving cell of the user equipment if a second report message, which is sent by the user equipment and carries a cell identifier of the second cell, is received before the arrival of a preset threshold in timing and the cell identifier of the second cell does not exists in the frequently changing cell identifier list. The method and the device disclosed by the invention are applied to the configuration and de-configuration process of the secondary serving cell.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a method and device for managing a secondary cell. Background technique [0002] At present, mobile broadband communication based on data services has become the development trend of mobile communication. In order to meet peak rate requirements and bandwidth requirements, the Long Term Evolution-Advanced (English: LongTermEvolution-Advanced, abbreviated: LTE-A) system introduces carrier aggregation (English: CarrierAggregation, abbreviated: CA) technology. Carrier aggregation technology refers to the aggregation of multiple continuous or discrete small frequency spectrums together to obtain a larger transmission bandwidth. Each aggregated frequency spectrum is called a component carrier, and each component carrier corresponds to a serving cell. [0003] A user equipment (English: UserEquipment, abbreviated: UE) that performs carrier aggregation transmission ...
