A method for establishing and using neighboring cells of a small cell

Abstract

The invention relates to a method for establishing and applying a neighboring cell of a small cell and belongs to the mobile communication field. The method comprises the following steps: initially electrifying the small cell; after the small cell is electrified, firstly searching a nearby macro eNB, acquiring a synchronizing signal of the macro eNB, and synchronizing the small cell to the macro eNB; searching nearby small cell deployment condition according to self capability by the small cell, searching all the nearby small cells and macro eNBs, and arranging according to signal strength to form a neighboring cell list, wherein information of the neighboring cell list includes a cell frequency point ARFCN (absolute radio frequency channel number) and a cell identity; and after normal initial starting up of the small cell is completed, adding the searched neighboring cell list into a system message, and according to a message broadcasting process, periodically broadcasting the neighboring cell list of the small cell. The method provided by the invention is applicable to configuration of the neighboring cell list in a current highly dense small cell scene, better user experience is provided, a mobile terminal is prevented from starting a blind search process, and power consumption of a mobile terminal is reduced.

Description

technical field [0001] The invention belongs to the field of mobile communication, and relates to a method for establishing and using an adjacent cell of a small cell. Background technique [0002] Mobile operators are worrying about increasing data traffic, and many operators believe that offloading mobile data is a good way to efficiently use wireless spectrum resources. Small cell (abbreviation: SmallCell) is an important component of third-generation mobile communication (abbreviation: 3G) data distribution. Many operators believe that SmallCell is an effective way to manage LTEA spectrum, not just using macro cells. [0003] The basic form of the Smallcell is a home base station (femtocell for short). Femtocell was originally designed to provide indoor coverage. Now the concept of femtocell is greatly expanded: metropolitan cellular (referred to as: metrocell), metrofemtocell, hotspot access femtocell, enterprise-level femtocell, super femtocell. Smallcell is more fr...

AI Technical Summary

Problems solved by technology

[0008] From the above analysis, it can be seen that no matter which method is used, the terminal needs to perform a blind search process. Although the problem of the adjacent cell list can be solved, there are still problems in the actual project, which will affect the actual user experience.

[0009] First: In the process of establishing the list of adjacent cells of the terminal, the terminal needs to perform a blind search process, which will greatly increase the power consumption of the mobile terminal, which will be a great test for the power saving of the mobile terminal

[0010] Second: Due to the deployment of high-density small cells and the principle of plug-and-play support, it is difficult for terminals to detect changes in small cell deployment in real time. If the frequency of blind search is increased, the power consumption of mobile terminals will increase ; If the frequency of blind search is reduced, it is impossible for the mobile terminal to monitor the actual situation of the surrounding cells in real time
