Description
Technical field
The present invention relates to cognitive radio technology, exactly, relate to a kind of intelligentized cognitive wireless network system of realizing heterogeneous network converged, be used for breaking through the limitation of existing network spectrum utilization, the availability of frequency spectrum that solves the existing network existence is hanged down and the isomerism problem, Effective Raise network spectrum utilance realizes the seamless fusion of heterogeneous wireless network, belongs to the network configuration technical field of wireless communication system network layer.
Background technology
The low pressure of the existing network availability of frequency spectrum has been alleviated in the appearance of cognitive radio technology.At present, cognitive wireless network system has been carried out certain research.The below briefly introduces wherein several typical schemes:
Referring to Fig. 1, introducing IEEE 802.22 is the Protocol REference Model that the TV channel in the frequency range of 47MHz～910MHz) proposes for fixing wireless area network (WRAN) works in 54MHz～862MHz VHF/UHF(extended frequency range, in order to support better cognitive radio technology, IEEE 802.22 has proposed the concept of cognitive plane (Cognitive Plane), cognitive plane is independent of datum plane and management control plane, realizes MAC layer Dynamic Spectrum Management function by introduce frequency spectrum perception function (SSF) and geographic positioning functionality in the physical layer on cognitive plane.The MAC layer on cognitive plane has defined spectrum management unit (SM), frequency spectrum perception automation cell (SSA) and Security Sublayer 2(SP).Between each layer module by different Service Access point SAP pass-along message.Wherein, spectrum management module SM is the core of IEEE 802.22, and its major function comprises: preserve usable spectrum information, channel classification and selection, jointly control, the channel status management, for the regional policy of frequency spectrum perception scheduling silent period, accessing database, execution IEEE 802.22 and supervision etc.IEEE 802.22 also provides database service, and inquiry and the update functions of data is provided for other functional modules.It mainly stores the frequency spectrum occupied information.
IEEE 1900 standards are by IEEE Standards Board issue, by defining a series of system architectures and agreement, so that under multiple wireless access technology environment, reach the purpose of improving whole wireless system integration capability and service quality.Referring to Fig. 2, brief introduction IEEE1900.4 systemic-function framework forms.
The network side framework has defined following four kinds of entities for characterizing network resource management: the spectrum management OSM of operator, and the RAN metrical information is collected RMC, and Network reconfiguration management NRM and RAN reshuffle control RRC.Wherein, OSM is used for realizing that operator is to the control of NRM dynamic frequency spectrum deployment decision-making.RMC collects the RAN contextual information and provides it to NRM.Use in the optimization at network-terminal distributed frequency spectrum, NRM is in charge of CWN and terminal.RRC reshuffles according to the Request Control RAN of NRM.
The end side framework has defined following three kinds of entities for characterizing the end side resource management: the terminal metrical information collects TMC, terminal reconfiguration management TRM and terminal is reshuffled control TRC.Wherein, TMC collects the terminal contextual information and provides it to TRM.When network-terminal distributed frequency spectrum used optimization, NRM was in charge of terminal.TRC reshuffles according to the Request Control terminal of TRM.NRM and TRM are the nucleus modules of IEEE 1900.4, and wherein NRM has defined six functions: tactful reasoning, and tactful efficiency evaluation, Network reconfiguration decision-making and control, the spectrum allocation may assessment, information extraction, collection, storage and RAN select.TRM has defined three functions: terminal is reshuffled decision-making and control, information extraction, collection, storage, and RAN selects.
ETSI RRS(Reconfigurable Radio System): reshuffling radio system RRS is one of etsi standard direction, is based on the generic concept of SDR and CR technology.RRS can utilize and reshuffle the ability that wireless function and network are adjusted for the dynamic change environment self-adaption, effectively solves incompatibility and the rare characteristic of frequency spectrum between the heterogeneous system, reaches the purpose that improves the availability of frequency spectrum.
The RRS groundwork is to provide the function structure of realizing system spectrum management under the isomerous environment, RRM and network element and terminal self-configuring management, referring to Fig. 3, introduce its function structure signal under single operator scenario (by introducing interface between the same functional module of different operators and can be generalized to multi-operator scenario belonging to).Function structure among the figure mainly comprises four functional modules: Dynamic Spectrum Management DSM, dynamic self-organization network analysis and management DSONPM, joint radio resource management JRRM and configuration control module CCM.Each functional module is not to work alone, and exists between them to be closely connected, and realizes the collaborative work of each module by the mode of introducing interface between the difference in functionality module.
Except providing function structure, because RRS is based on cognitive radio CR(Cognitive Radio) technology, must there be terminal perceived spectral link in system, for time and the energy that reduces the terminal perceived spectral, between base station and terminal, introduced cognitive pilot channel CPC, be used for being reconstructed required software and download and the cognitive information transmission, solve public download channels and signaling control problem in the reconstruct.
Than IEEE 1900.4, RRS repartitions systemic-function, and has proposed the transmission of CPC support cognitive information, and the relation between IEEE 1900.4 and the ETSI RRS function structure as shown in Figure 4.As can be seen from Figure 4, the RRS groundwork is that function with NRM module among the IEEE 1900.4 is refined as DSM, DSONPM, CCM and JRRM.TRM, TRC and the TMC function of end side are finished by the end side of CCM module and JRRM module simultaneously.
Sum up the present situation of above-mentioned various prior aries, find to exist following shortcoming:
Existing cognitive wireless network system does not possess the perception multi-domain environment ability of (mainly comprising user environment, network environment, wireless environment and policy management), lacks complete multi-domain environment representation system and the database of multi-domain environment cognitive information.For example, IEEE 802.22 does not possess intelligence learning/inference function, and IEEE 1900.4 and ETSI RRS only possess simple learning ability, do not possess the ability of autonomous learning, lacks the unified management that network intelligence is processed.IEEE 802.22 does not possess re-configurability for Television Broadcasting Network.There have been fairly perfect reconfiguration management function in EEE 1900.4 and ETSI RRS, but lack certain intelligent.
