In the frequency spectrum of license, the data business volume of increase has made operator will consider at least some in traffic carrying capacity to be unloaded to and to provide the local node of this locality access to the Internet or other networks to reduce the congested replacement scheme of core network.For example, the femtocell operating in the frequency spectrum of license can be served local node, and can promote to the Internet or this locality of other networks access.But anticipatory data traffic carrying capacity will continue to increase, and just because of this, operator continues seeking for other selections from core network unloading traffic carrying capacity.
In this respect, operator is just considering to utilize unauthorized frequency spectrum (also referred to as shared frequency spectrum) so that at least some traffic carrying capacitys in supported data traffic carrying capacity.In unauthorized frequency spectrum, defined various shared frequency bands, example comprises industry, science and medical treatment (ISM) frequency band and TV white space (TVWS) simultaneously.In order to coordinate the use of frequency spectrum, such as the use of TV white space, develop and followed IEEE(Institute of Electrical and Electric Engineers) coexistence manager of 802.19.1.Coexistence manager is that radio access technologies (RAT) independently and conventionally focuses on the coordination that the frequency spectrum between the technology based on IEEE on transmission control protocol (TCP)/Internet protocol (IP) uses.Due to its RAT independence, coexistence manager is extendible solution, and can correspondingly interact from multiple different systems.Just because of this, coexistence manager can be used as relatively high-grade telegon, and it can promote the negotiation about spectrum utilization between RAT, or can local management for sharing the spectrum utilization of frequency spectrum.Coexistence manager can operate in relatively large time scale, and coexistence manager is more much bigger than the time quantum of the physical layer of system to the reaction time of the interference problem between system.Therefore, expect to provide the coordination of the less time scale between the system of being coordinated by coexistence manager.
From the angle of Long Term Evolution (LTE), such as the access point of the LTE of enode b (eNB) can operate in unauthorized frequency spectrum.The deployment bandwidth of carrier wave and the quantity of utilizing due to their administrative institute and the ability reconfiguring flexibly that allows centre frequency, LTE can be for providing advantage with respect to the operation meeting in the unauthorized frequency spectrum of IEEE802.11 standard.
LTE is because the result of the support of the relation of the multi-to-multi between its Universal Mobile Telecommunications System (UMTS) terrestrial radio access network (E-UTRAN) node and block core (EPC) node of evolution to evolution supports radio access network shared.In this respect, the network share framework of being supported by LTE allows different core network carrier to be connected to shared radio access network.Radio network element is not only shared by operator, and also can share radio resource itself.Except shared radio access network, operator can selectively have additional dedicated radio access network, such as the second generation (2G) radio access network.
Due to advantage and the operability of LTE access point in unauthorized frequency spectrum that LTE system provides, therefore can expect to improve the coordination between LTE system, such as the coordination of the less time scale between LTE system, to utilize better those advantages.In addition, can expect to improve the coordination between the LTE system being provided by coexistence manager.
