Problems solved by technology

However, the load balancing technology in the prior art may lead to a decrease in the communication quality of the user equipment after being handed over, and may also cause the handover failure of the cell to which the user equipment needs to be handed over due to reasons such as being unable to serve too many user equipments.

Embodiment Construction

[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0023] figure 1 It is a flowchart of a method for handing over a user equipment in a cell to its neighboring cell in a preferred embodiment of the present invention. The method in this embodiment is mainly implemented by one device. Preferably, the device can be located in the base station; or, the device can be distributed, with part located in the base station and part located in multiple cells belonging to the base station.

[0024] The method according to this embodiment includes the following steps S1, S2, S3 and S4.

[0025] In step S1, the device selects user equipment that can be handed over to a neighboring cell of the cell according to the PRB usage information of the cell or part of the cell where it is located and the communication-related information of the user equipment in the cell.

[0026] Wherein, the PRB usage information can be used to ...

Abstract

The invention provides a method and a device for switching user equipment from a cell to a neighboring cell. The method comprises the following steps of according to PRB (physical resource block) use information of the cell and the relevant communication information of the user equipment in the cell, selecting the user equipment which can be switched to the neighboring cell; sending first request information to the selected user equipment; receiving a communication measuring report provided by the selected user equipment; according to the communication measuring report and the comprehensive available capacity information provided by the neighboring cell, determining the required neighboring cell for switching of all or part of the selected user equipment, and executing the corresponding switching of the user equipment. The method and the device can reduce the possibility of degrading of service quality when the selected user equipment is switched to the neighboring cell, and the possibility of failure of switching when the selected user equipment is refused by the neighboring cell.

Description

technical field [0001] The present invention relates to the field of communication technology, and in particular to a method and device for handing over user equipment in a cell to its adjacent cell. Background technique [0002] In the 3GPP LTE system, the load balancing technology needs to realize the unbalanced distribution of communication load among multiple cells. It needs to try to maintain a high utilization rate of wireless resources and maintain the quality of service of ongoing sessions as well as possible. A persistently low dropout rate may re-handover user equipment to shift the communication load from more heavily loaded cells to underutilized cells. [0003] It can be seen that load balancing needs to select a user equipment from a cell with a higher load and hand over to a cell with a lower load. However, the load balancing technology in the prior art may lead to a decrease in the communication quality of the user equipment after being handed over, and may ...
