Problems solved by technology

However, the cost of the BBU is relatively high, which brings pressure to the expansion work
Moreover, every time the communication system is expanded, it is necessary to artificially add antennas and corresponding RRUs, and may further need to add BBUs, which takes up more human resources.
If more antennas and cells are built at the initial stage of network construction, it will lead to waste of communication system resources
[0005] It can be seen that in order to meet the needs of the development of communicati

Abstract

The invention discloses a method for cell-networking, which is used for realizing the flexible planning of a cell and the cell networking in various forms, and improving the availability of a frequency spectrum or saving network resources. The method comprises cell split and cell merge. The cell split method and the cell merge method comprise cell establishment and cell deletion. The cell split method comprises the following steps: calculating the occupation situations of physical resources on a plurality of antennae corresponding to the same cell; determining the physical resources occupied being not less than the prearranged threshold value continually within the prearranged time, and determining to carry out the cell split when reaching the prearranged time; splitting the same cell into at least two cells; and respectively allocating the antennae to the two cells. The cell merge method is similar to the cell split method. The invention further discloses a device, a distributed typebase station and an internal unit thereof for planning a cell.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and a system for realizing community networking. Background technique [0002] In the current prior art, a common antenna or a smart antenna including multiple antenna units corresponds to a cell. With the rapid development of communication users and communication services, the existing cell resources can no longer meet the demand. In order to expand the communication system, one way is to increase the number of antennas to increase the cell resources. The signals are merged into one signal. [0003] In traditional base station systems, analog signals are transmitted between the baseband and transceivers. The analog signal can be superimposed directly through the transmission line and sent to the baseband side for processing. However, during the transmission of the analog signal, the analog signal will continue to attenuate as the transmission distance increases. In the pro...
