Dynamic cooperative coverage method among base stations

Abstract

The invention relates to mobile wireless communication, in particular to a dynamic cooperative coverage method among base stations. In the prior art, only how to control cell base stations under a static condition is considered, the number of users and the random time-variant characteristic of positions of the users are not considered, and communication blind spots can not be efficiently and accurately covered after one cell is dormant. The dynamic cooperative coverage method among the base stations carries out forecasting according to the number of users of a grey markov model and combines zonal statistics, and the base stations of other neighborhood cells can efficiently, timely and accurately cover all users in the dormant cell when one cell base station is dormant.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a dynamic cooperative coverage method between base stations. Background technique [0002] With the continuous promotion of 3G and 4G technologies, more and more new base stations are put into operation, which not only causes energy waste, environmental pollution and other problems, but also greatly increases operating costs. Therefore, research on efficient energy-saving communication modes is imminent. [0003] In 2010, IEEE's 21st International Symposium comprehensively described the communication mode of applying base station sleep mode in 2G / 3G network to save energy consumption. The core idea is that when the load in the coverage area of ​​a base station is extremely low or there is no load, we can save a lot of unnecessary energy consumption by turning off the base station or maintaining the base station in an extremely low power mode. On the other hand, in 2009, some r...

Problems solved by technology

[0005] However, in the real wireless communication environment, the distribution of mobile users in time and space is irregular. It is difficult to achieve efficient energy saving without making real-time cooperative decisions between base stations by monitoring changes in the surrounding environment. communication mode

However, in the prior art, most methods only consider how to control the cell base station under static conditions, and do not consider the random time-varying characteristics of the number of users and user locations. Therefore, in the case of dynamic changes in the network load environment, how to sleep in a certain cell Finally, the problem of efficient and accurate coverage of communication blind spots still needs to be solved urgently
