Heterogeneous network energy saving method based on cognition technology

Abstract

The invention discloses a heterogeneous network energy saving method. The method comprises the steps as follows: a macro base station user determines whether HeNB (Home evolved NodeB) is accessed or not according to the quality of a signal; when the signal-noise ratio of the HeNB is larger than or equal to that of the macro base station, the HeNB is accessed, if not, the HeNB is not accessed; and after the HeNB is accessed into the macro base station, macro base station transmitting power and accessed HeNB transmitting power, and the minimum value of the transmitting power of the macro base station is reserved to ensure the service quality. According to the invention, firstly, pricing technology is used for exciting the HeNB to receive the user of the macro base station, thereby offering better service for users located in special positions and enlarging the throughput capacity of a system; in addition, interference between the macro base station and the HeNB, and HeNBs is lowered via distributed power control, so as to achieve the maximization of the energy efficiency of the system; and lastly, owing to the reduction of the transmitting power of the macro base station, energy conversation is realized, and the operation cost of operators is lowered.

Description

technical field [0001] The invention belongs to the field of wireless communication, and in particular relates to a cognitive technology-based energy-saving method for heterogeneous networks. Background technique [0002] Existing statistics show that 60% of voice services and 90% of data services are generated in indoor environments such as homes, offices, airports, or schools. Therefore, operators are faced with how to provide better indoor coverage and maximize network capacity with a more reasonable price-performance ratio. However, the user experience in the current macro cellular network is not optimistic. The macro-cell evolved-NodeB (eNB) in the Universal Mobile Telecommunications System (UMTS) Long Term Evolution (LTE) network is adopting a high-power transmission mode in order to better guarantee the service quality of end users. However, on the one hand, high-power transmission consumes a lot of energy resources, and on the other hand, it causes a lot of harm to...
