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 that differs from one another arises at the historic moment.These networks are when bringing excellent communications to experience for the user, for operator and user administrator have been brought bigger complexity at operation, use and management aspect, the difficult problem of the frequency spectrum resource shortage that brings thus also put operator and gerentocratic in face of.The shortage problem of heterogeneous wireless access technology coexistence, frequency spectrum resource has become the basic problem that the restriction wireless mobile communications develops towards directions such as broadband, ubiquitousization.In recent years, in order to address the above problem cognition network has been proposed.Cognition wireless network is owing to have characteristics that dynamic spectrum inserts and to the support of heterogeneous wireless network convergence, shown great advantage day by day.
The notion of cognitive radio (CR) was proposed by Mitola in 1998 at first.Cognitive radio is a kind of intelligent radio power technology with environment cognitive ability based on Software Radio platform.It has by the study that changes wireless environment on every side being finished the ability of self reshuffling.The notion 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 notion of cognition wireless network is suggested subsequently.Cognition wireless network should possess a cognitive process, comprises the process to observation, reasoning and study, decision-making and the execution of current spectrum environment, wireless environment network environment, user environment etc., so circulation.Cognition wireless network is adjusted self-teaching by these and is disposed and obtain best end-to-end usefulness with the optimization that reaches wireless network resource.And the realization of this process needs the corresponding protocol support to realize in the network the mutual of information between each node.With spectrum cognitive information is example, each terminal in the network need report base station side function corresponding entity with the spectrum information of collecting or detect, network side is made a strategic decision the information fusion storage that each side reports afterwards according to relevant optimized Algorithm, and decision-making issued, each network node is carried out after receiving decision information then.Above-mentioned cognitive information reports, making a strategic decision 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 that proposes in the E2R of European Union project and the E3 project, promptly cognitive pilot channel (CPC) technology.Cognitive pilot channel technology adopts broadcast mode or demand mode, by specific signaling channel with the network information, be broadcast to subscriber equipment as available carriers information, available wireless access technology information, usable frequency information etc., share with the dynamic spectrum that is implemented under the cognitive environment.Present cognitive pilot channel solution all is 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 is comprising the geographical location information in each grid.At first monitor broadcast channel behind the starting up of terminal, and judge, obtain the heterogeneous network information in the grid of own place according to geographical location information in the grid information and the positional information of self.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 then sends to terminal according to location information of terminals with 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 the heterogeneous wireless network, so it needs a whole world fixing arrowband frequency range or one group of frequency range collection to carry, and the propagation characteristic of this frequency range will well could satisfy the requirement that grid Da Qu covers.And in frequency spectrum resource rare day by day today, especially the good frequency range of propagation characteristic is made his usefulness by the distribution of the radio frequency band administrative department of various countries already, and the scope in the whole world 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 its narrow-band characteristic has also determined cognitive pilot channel can't transmit a large amount of cognitive information.Want transmission requirements so be with the realization of outer cognitive pilot channel can't satisfy cognitive information a large amount of in the future network in this respect.Its two, if cognitive pilot channel is operated under the broadcast mode, be unidirectional end side to be carried out the broadcasting of cognition network information by network side.Like this, network side is in different wireless environments, network environment with each and has 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 the broadcast mode does not have to reflect the approach of end side cognitive information, can't report for the end side cognitive information of cognition wireless network to provide support, thereby also can't realize the raising of the network performance that cognitive function brings.Though and demand mode provides up approach, the heterogeneous network information request that just will comprise own geographical location information sends to network side, and function ratio is more single.And more for a long time, because the narrow-band characteristic of first said cognitive pilot channel, cognitive information can experience sizable time delay under demand mode at some hot zones terminal quantity, even owing to asking too much or the long instability that causes system of queuing delay.
