Embodiment Construction

[0046] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0047] The main solution of the embodiment of the present invention is: when the gateway receives the handover request from the macro base station, it judges whether there is a PCI confusion problem in the adjacent cell of the macro base station; when there is a PCI confusion problem, and the target base station managed by the gateway When the reserved resources are sufficient, select the reserved resources; send the switching request to at least one target base station, and the switching request carries the serial number of the selected reserved resources, so that the target base station that receives the switching request can use the The number returns a handover response to the gateway; the gateway receives the handover response, and sends a preset message to the macro base station according to the handover response...

Abstract

The invention discloses a base station networking method. The base station networking method comprises steps of determining whether a macro base station adjacent area has a physical cell identity PCI confusion problem or not when a gateway receives a switching request from the macro base station; selecting reserved resources when the PCI confusion problem exists and reserved resources of target base stations managed by the gateway are sufficient; sending the switching request to at least one target base station, wherein the switching request carries numbers of the selected reserved resources, so that the target base stations which receive the switching request can return switching responses to the gateway according to the numbers; and sending a preset message to the macro base station by the gateway according to the switching responses after the gateway receives the switching responses, so that user equipment is enabled to carry out switching. The invention also discloses a base station networking apparatus. The mobility performance index of macro-micro networking is improved.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a base station networking method and device. Background technique [0002] In LTE (Long Term Evolution, long term evolution), PCI (Physical Cell Identifier, PCI) is used to distinguish radio signals of different cells. The LTE system provides 504 PCIs, similar to the concept of 128 scrambling codes in the TD-SCDMA (Time Division-Synchronous Code Division Multiple Access) system. a number. [0003] In the field of modern wireless communication, based on the planned networking of the original large base stations, that is, macro base stations, the demand for distributed small base stations, that is, micro-station networking, is also increasing. The use of micro-stations brings user experience The rise of the base station has the advantages of fast and convenient construction. There are multiple micro-stations in the coverage area of ​​each macro base station, and the...
