Embodiment 1

[0109] see figure 1 , which shows a flow chart of a handover method based on carrier aggregation provided by the present invention, the method is applied to a source base station, and specifically includes:

[0110] Step 101, a source base station receives a measurement report reported by a UE (User Equipment, user equipment). Wherein, the measurement report includes information of the source primary cell, information of the source secondary cell, information of adjacent cells of the source primary cell, and information of adjacent cells of the source secondary cell.

[0111] Step 102, the source base station generates a candidate cell list according to the measurement report.

[0112] The measurement report includes information of all cells measured by the UE, such as source primary cell information, source secondary cell information, neighbor cell information of the source primary cell, and neighbor cell information of the source secondary cell. specific as Figure 1a As ...

Embodiment 2

[0142] On the basis of the above examples, if figure 2 As shown, it shows another flow chart of a handover method based on carrier aggregation provided by the present invention. After the source base station sends the handover command to the UE, it also includes:

[0143] Step 201, the source base station judges whether a handover completion message sent by the target base station is received within a first preset time. If received, perform step 202, and if not received, perform step 203.

[0144] Wherein, the first preset time can be flexibly set according to actual needs.

[0145] Specifically, step 201 may include starting a timer after the source base station sends a handover command to the UE. A timer is used to time and judge whether the first preset time is reached.

[0146] Step 202, releasing the primary cell information and secondary cell information of the source base station.

[0147] Step 203, release the configuration information of the secondary cell in the...

Embodiment 3

[0151] see image 3 , which shows another flow chart of a handover method based on carrier aggregation provided by the present invention, the method is applied to a target base station, and specifically includes:

[0152] Step 301, the target base station receives a handover request message sent by the source base station. Wherein, the handover request message includes the identity of the source primary cell, the identity of the target primary cell, the identity of the UE, and a list of candidate cells.

[0153]Preferably, the handover request message may also include aggregated secondary cell information in the source base station.

[0154] Step 302, the target base station judges whether the target primary cell satisfies the handover requirement according to the target primary cell identifier. If the target primary cell meets the handover requirement, go to step 303, otherwise go to step 308.

[0155] Specifically, judging whether the target primary cell meets the handove...

Abstract

The invention provides a carrier-aggregation-based switching method, and an inter-board polymerization switching method and device. The carrier-aggregation-based switching method comprises the following steps: receiving a measurement report reported by UE; generating a candidate cell list according to the measurement report; judging whether a target main cell meets the switching requirement; sending a switching request message to a target base station when the target main cell meets the switching requirement; receiving a switching request confirmation message sent by the target base station; sending a switching command to the UE, wherein the switching command comprises configuration information of the target main cell and configuration information of successfully configured aggregation auxiliary cell so as to reconfigure a novel target main cell and a aggregation auxiliary cell according to the configuration information of the target main cell and the configuration information of successfully configured aggregation auxiliary cell after the UE receives the switching command. Consequently, the carrier aggregation in the switching technology which supports the carrier aggregation can be used for supporting the switching between one UE and service communication of a plurality of cells.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, and more specifically, to a handover method based on carrier aggregation, an inter-board aggregation handover method and a device. Background technique [0002] The LTE (Long Term Evolution, long-term evolution) system refers to an evolution solution adopted to ensure the competitiveness of the 3GPP for a long time. It is mainly based on WCDMA (Wide band Code Division Multiple Access, wideband code division multiple access), by changing the network architecture and adopting new air interface technology to reduce system complexity and cooperate with different systems. [0003] Carrier aggregation technology aggregates discrete spectrum segments (Spectrum Fragment) whose channel capacity is difficult to support high-bandwidth demand services into a complete spectrum with large channel capacity, thereby supporting higher system bandwidth and improving spectrum utilization.
