Cellular communication system and cell filtering method thereof

Abstract

The invention discloses a cellular communication system and a cell filtration method thereof. The communication system comprises user equipment and a plurality of base station devices, and the base station devices comprise a macro base station, a micro base station and a home base station; a neighbor cell list is established in the macro base station and the home base station, and the list comprises neighbor cell information of neighbor macro base station and home base stations; the neighbor cell list comprises the following attributes: neighbor cell information, tracking cell identification of cells, whether the cells are private, whether the cells can be switched, and whether X2 interfaces exist; the neighbor cell information of the macro base station comprises cell information of adjacent macro base stations and home base stations within the coverage range; and the neighbor cell information of the home base station comprises cell information of adjacent home base stations and cell information of macro base stations where the home base stations are positioned. The cellular communication system and the cell filtration method thereof can reduce signaling cost and improve switching performance.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and relates to a cell filtering method, in particular to a cell filtering method of a cellular communication system; the invention also relates to the aforementioned cellular communication system. Background technique [0002] In most parts of the world, new networks will be deployed in higher frequency bands, and high frequencies are less penetrating than low frequencies, so femtocells will be an attractive approach. A femtocell is a residential cellular access point for use in home and office environments. It accesses the core network of the mobile operator through the user's broadband connection (eg, DSL), which can compensate for weaker indoor signals and provide the bandwidth required by the network. Femtocells provide high-quality voice, optimal data rates, and cheaper tariffs for calls and connections made at home. Femtocells provide the best coverage for the vast majority...

AI Technical Summary

Problems solved by technology

[0004] 3GPP has conducted some research on femtocells, but the application of femtocells may still bring challenges to related work on new types of networks in the future

In border scenarios, the terminal may not be able to distinguish cells from different operators, in which case the terminal does not need to report these cell information

In addition, the terminal needs to maintain a white list of all CSG IDs that can be accessed. In the future, the number of CSG cells will be huge. All femtocells deployed in public areas (such as airports and shopping malls) are all CSG cells that the terminal can access. The number of CSGs maintained will be large, further increasing the burden on the terminal
