Embodiment Construction

[0027] The present invention will be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are illustrated. The exemplary embodiments of the present invention and their descriptions are used to explain the present invention, but do not constitute an improper limitation of the present invention.

[0028] The following description of at least one exemplary embodiment is merely illustrative in nature and in no way taken as limiting the invention, its application or uses.

[0029] As mentioned above, according to statistics, more than 50% of voice services and more than 70% of data services will take place indoors in the future, and femtocell technology is an effective way to ensure indoor coverage of future mobile communication systems (LTE-A) and improve system throughput. means that the quality of service for its users needs to be guaranteed.

[0030] After earnest research, the inventor changed the existi...

Abstract

The invention discloses a spectrum resource accessing method and system. The spectrum resource accessing method includes the following steps that a macro base station and a family base station judges whether spectrum resources which authorize the macro base station and the family base station can meet the service requirements or not respectively; if the spectrum resource which authorizes the macro base station can not meet the service requirement of the macro base station, the macro base station perceives whether a frequency band which is not used by the family base station exists or not in the range of the spectrum resource which authorizes the family base station, and if the frequency band which is not used by the family base station exists, the perceived frequency band which is not used by the family base station is distributed to the macro base station; if the spectrum resource which authorizes the family base station can not meet the service requirement, the family base station perceives whether a frequency band which is not used by the macro base station exists or not and if the frequency band which is not used by the macro base station exists, the perceived frequency band which is not used by the macro base station is distributed to the family base station. The spectrum resource accessing method and system can not only improve the utilization rate of the spectrum resources, but also can effectively ensure service quality of an indoor user.

Description

technical field [0001] The present invention relates to the field of home base stations, and in particular, to a method and system for acquiring frequency spectrum resources. Background technique [0002] According to relevant statistics, more than 50% of voice services and more than 70% of data services in future mobile communication systems will occur indoors, and indoor, low-speed and hotspots will become more important application scenarios in the future mobile Internet era. Therefore, 3GPP LTE- One of the priorities of Advanced is to optimize the indoor scene to meet the needs of future users for voice and high-speed data service transmission in the indoor scene. [0003] Femtocell (Home NodeB, home base station) technology, as an effective means to improve the service quality of indoor users' voice and high-speed data services, has become more and more popular in the industry due to its low power consumption, low cost, plug and play and flexible configuration. of favo...
