Description
Technical field
The present invention relates to a kind of in heterogeneous communication system the network information compile and broadcasting method, particularly about a kind of application awareness pilot channel collection network information and to the method for terminal broadcast.
Background technology
At present, telecommunications world is experiencing some basic changes to adapt to the user's request that increases day by day and change irregularly.The most interesting research point is at wireless communication field, and main purpose is to realize quicker, easy communication.Existing wireless communication technology comprises multiple wireless access standard: gsm system, gprs system, UMTS system, BWA, WLAN, digital picture broadcast system (DVB), CDMA2000 system, PHS system, satellite communication, satellite fix and various short-range communication standard.Because the difference of design object and range of application, these equipment will be extensively, be present in our life chronically.These are the wireless communication system of a distribution on global collaborative work of wireless access technology composition independently, is referred to as heterogeneous wireless communication system.Its target is the requirement according to the user, under acceptable cost performance condition, with collaborative mode be the user provide have novelty, the quality services more of otherness.This just means that Virtual network operator can use different wireless access technologys as the user suitable service to be provided under different time and specified conditions such as space.The network that is fit to is selected to insert according to user preference, network context and business need in terminal (reshuffling the terminal) with the ability of reshuffling.Therefore, to accomplish the access of network selecting property most important for promptly and accurately grasp network information counterweight configurating terminal.But dynamic frequency spectrum deployment (DynamicSpectrum Allocation; DSA) and flexible spectrum management (Flexible SpectrumManagement, FSM) etc. the application of dynamic frequency spectrum deployment scheme makes and reshuffles the operation frequency range that the terminal can't be confirmed the different radio access network in time, accurately.At this moment, reshuffle the terminal and must carry out full range scanning to find current alternative Radio Access Network and to move frequency range accordingly.But this process is consuming time long; Thereby and can consume a large amount of electric energy and shorten terminal service time; Even carry out full range scanning; Because the reconfiguration software of reshuffling terminal storage is limited, can not self reprovision be set to every kind of wireless access technology and scan finding corresponding Radio Access Network, and the stride of scanning also there is tremendous influence to scanning result.It is thus clear that full range scanning can not really solve the problem that the terminal can't obtain the network information of reshuffling in the heterogeneous wireless communication system.
At present, the scheme of head it off have only the band outer perception pilot channel (the out-bandCognitive Pilot Channel, CPC).The outer perception pilot channel of this band is used the consistent frequency range broadcast network information in the whole world.Thereby reshuffle the terminal and extract the access of network information completion network selecting property through monitoring this perception pilot frequency channel.But there is certain problem in the outer perception pilot channel of this band.At first, because the spectrum allocation schemes of various countries is relatively independent at present, be difficult to find the frequency range of one section global general-use to carry the outer perception pilot channel of band; Secondly, because the outer perception pilot channel of this band carries out the broadcasting of the network information in the world, its amount of information is huge, even exist such global general-use frequency range also to be not enough to carry so huge amount of information so.Therefore, propose a kind of scheme and divide three levels to broadcast global network information: ground floor: country's layer, information comprises: country code; The second layer: the operation quotient sheaf, information comprises: the code of each operator in this country; The 3rd layer: the Radio Access Network layer, information comprises: the Radio Access Network code of this operator's operation and operation frequency range thereof.Still there is defective in this scheme: reshuffle the Radio Access Network of its operation can't be learnt in the terminal before confirming operator situation, just can't obtain the comprehensive network information.
Based on analysis to the demand and present Research, solve the problem that the network information provides in the existing heterogeneous wireless communication system, we have designed a kind of application awareness pilot channel collection network information and to the method for terminal broadcast.The network selecting property access that the configurating terminal of attaching most importance to provides in time, thereby accurate, the comprehensive network information realizes fast, optimizes.
