Embodiment 1

[0345] Such as image 3 As shown, the embodiment of the present invention provides a handover method, the method is executed by the target main base station, including:

[0346] 301: The target MeNB receives a handover request sent by the source MeNB, the handover request includes first configuration information of the source SeNB, and the source MeNB and the source SeNB jointly provide services to the user equipment.

[0347] 302: The target primary base station sends a first indication to the source secondary base station, where the first indication is used to indicate that the source secondary base station remains unchanged.

[0348] 303: The target primary base station sends a handover confirmation to the source primary base station, where the handover confirmation includes second configuration information of the source secondary base station, and is used for the target primary base station and the source secondary base station to jointly provide services to the user equip...

Embodiment 2

[0412] Such as Figure 6 As shown, the embodiment of the present invention provides a handover method, the method is executed by the target main base station, including:

[0413] 601: The target primary base station receives a handover request sent by the source primary base station, the handover request includes configuration information of the source secondary base station, and the source primary base station and the source secondary base station jointly provide services to the user equipment;

[0414] 602: The target primary base station sends a first indication to the target secondary base station, where the first indication is used to indicate that the target secondary base station is the secondary base station of the user equipment; and

[0415] 603: The target primary base station sends a handover confirmation to the source primary base station, where the handover confirmation includes configuration information of the target secondary base station, and is used for the t...

Embodiment 3

[0448] One-to-one with the implementation, such as Figure 8 As shown, the embodiment of the present invention provides a switching device, Figure 8 The shown device can be the target main base station, or the target main base station uses Figure 8 The device shown performs base station switching, Figure 8 The devices shown include:

[0449] The transceiver 801 is configured to receive a handover request sent by the source primary base station, where the handover request includes first configuration information of the source secondary base station, and the source primary base station and the source secondary base station jointly provide services to the user equipment;

[0450] The processor 802 is configured to trigger the transceiver 801 to send a first indication to the source SeNB, where the first indication is used to indicate that the source SeNB remains unchanged; and, trigger the transceiver 801 to send a handover confirmation to the source MeNB, and the handover c...

Abstract

The invention provides a switching device and method, which are used for keeping a source auxiliary base station unchanged in the switching process of a main base station of user equipment, reducing the time delay in the switching process of the base station and avoiding the problem of interruption of data communication between the user equipment and the source auxiliary base station in the switching process of the base station. The switching method provided by the invention comprises the following steps that: a target main base station receives a switching request sent by a source main base station, the switching request comprises first configuration information of a source auxiliary base station, and the source main base station and the source auxiliary base station jointly provide service for user equipment; the target main base station sends a first indication to the source auxiliary base station, wherein the first indication is used for indicating that the source auxiliary base station remains unchanged; and the target main base station sends a switching confirmation to the source main base station, and the switching confirmation comprises second configuration information of the source auxiliary base station and is used for the target main base station and the source auxiliary base station to jointly provide service for the user equipment.

Description

technical field [0001] The present invention relates to the communication field, in particular to a switching device and method. Background technique [0002] Dual Connectivity (Dual Connectivity) technology is also known as inter-base station carrier aggregation technology or multi-stream aggregation technology. Dual connectivity technology means that user equipment receives data from at least two base stations at the same time, that is, master base station (master base station or primary base station) and A secondary base station (secondary base station) simultaneously provides communication services for user equipment. A typical scenario is that the user equipment receives data from the macro base station and the small base station at the same time. The macro base station serves as the main base station to provide wide coverage to reduce the number of handovers, and the small base station serves as the secondary base station to share data to improve the capacity of hotspo...
