Description
Technical field
The present invention relates to the cognition wireless network technology, relate in particular to a kind of method, system, the network equipment and terminal equipment of the transmitting cognitive network information.
Background technology
Along with the fast development of wireless access technology, the heterogeneous radio access networks network differed from one another arises at the historic moment.These networks are when bringing good communication experiences for the user, for operator and user administrator have been brought larger complexity at operation, use and management aspect, the difficult problem of the frequency spectrum resource shortage brought thus also put operator and gerentocratic in face of.The heterogeneous wireless access technology coexists, the shortage problem of frequency spectrum resource has become the basic problem of restriction wireless mobile communications towards future developments such as broadband, ubiquitousization.In recent years, in order to address the above problem, cognition network has been proposed.Cognition wireless network, due to the characteristics with dynamic spectrum access and to the support of heterogeneous wireless network convergence, has shown great advantage day by day.
The concept of cognitive radio (CR) was proposed by Mitola in 1998 at first.Cognitive radio, based on Software Radio platform, is a kind of intelligent radio power technology with environment cognitive ability.It has by the study to changing wireless environment on every side and completes the ability of self reshuffling.The concept of cognitive radio is only limited to single network node, is difficult to give full play to the improvement of cognitive features to network performance.The concept of cognition wireless network is suggested subsequently.Cognition wireless network should possess a cognitive process, comprises observation, reasoning and study, decision-making the process of carrying out, so circulation to current spectrum environment, wireless environment network environment, user environment etc.Cognition wireless network is adjusted self-teaching by these and is configured and obtain best end-to-end usefulness with the optimization that reaches wireless network resource.And the realization of this process needs corresponding agreement support to realize in network the mutual of information between each node.Take spectrum cognitive information as example, each terminal in network need to report the corresponding functional entity of base station side by the spectrum information of collecting or detect, carry out decision-making according to relevant optimized algorithm after the information fusion storage that network side reports each side, and decision-making is issued, then each network node is carried out after receiving decision information.Above-mentioned cognitive information reports, decision-making issues and the record of historical information all needs one to support the rational protocol architecture of cognitive function and concrete signaling support.
For the support to the cognitive information transmission is provided, more representational technology is the shared common signal channel of heterogeneous network proposed in the E2R of European Union project and E3 project, i.e. cognitive pilot channel (CPC) technology.Cognitive pilot channel technology adopts broadcast mode or demand mode, by specific signaling channel by the network information, as available carriers information, available wireless access technology information, usable frequency information etc. are broadcast to subscriber equipment, to realize the dynamic spectrum under cognitive environment, share.Current cognitive pilot channel solution is all to be based upon on the basis of grid division, and the pattern that information sends comprises broadcast mode and some broadcast mode.In broadcast mode, cognitive pilot channel base station periodic broadcast heterogeneous network information, comprising the geographical location information in each grid.At first listening broadcast channel after starting up of terminal, and judged according to the geographical location information in grid information and the positional information of self, the heterogeneous network information in the grid of own place obtained.In demand mode, the heterogeneous network information request that terminal will comprise own geographical location information sends to cognitive pilot channel base station, and cognitive pilot channel base station sends to terminal according to the positional information of terminal by the cognitive information of corresponding grid.
But there are some shortcomings in the scheme of prior art.For example, because cognitive pilot channel outmatches on heterogeneous wireless network, so it needs fixing arrowband frequency range or one a group of frequency range collection in the whole world to carry, and the propagation characteristic of this frequency range will well could meet the requirement that grid great Qu covers.And at frequency spectrum resource day by day rare today, especially the good frequency range of propagation characteristic is distributed and is used as him by the radio frequency band administrative department of various countries already, in global scope, is that unified one section frequency range or one group of frequency range collection are all unrealistic as cognitive pilot channel.Even if under the promotion of various countries' political strength, unified frequency range can be decided.Because also having determined cognitive pilot channel, its narrow-band characteristic can't transmit a large amount of cognitive information.So the realization of the outer cognitive pilot channel of band can't meet the demand that cognitive information a large amount of in future network will be transmitted in this respect.Its two, if cognitive pilot channel is operated under broadcast mode, be the unidirectional broadcast of cognition network information of end side being carried out by network side.Like this, network side by each in different wireless environments, network environment and there is the same and opinion of the terminal of different user demands, for each terminal provides same cognition network information.So the cognitive pilot channel under broadcast mode does not have to reflect the approach of end side cognitive information, can't report and provide support for the end side cognitive information of cognition wireless network, thereby also can't realize the raising of the network performance that cognitive function brings.Although, and demand mode provides up approach, the heterogeneous network information request that just will comprise own geographical location information sends to network side, function ratio is more single.And, when some hot zones terminal quantity is more, due to the narrow-band characteristic of first said cognitive pilot channel, cognitive information can the sizable time delay of experience under demand mode, even due to request too much or queuing delay is long causes the unstable of system.
