Detailed description of the invention
Below in conjunction with specific embodiment, further set forth the present invention. Should be understood that these embodiment are only for illustrating the present inventionBe not used in and limit the scope of the invention. In addition should be understood that after having read the content of the present invention's instruction art technology peopleMember can make various changes or modifications the present invention, and these equivalent form of values fall within equally the application's appended claims and limitScope.
As shown in Figure 1, the present invention is based on a kind of heterogeneous network selective system that is applicable to public place, it comprise have wirelessMovable-type intelligent terminal and the server of communication function. The each mobile subscriber who holds movable-type intelligent terminal is entering many networksStack overlay area, can carry out after the server of information interaction when search, can manually access in advance a certain network. MobileClient business on formula intelligent terminal is that user initiatively initiates. In the time carrying out a new business, client can gather current instituteAt network parameters such as network, network enabled type, type of service, service priority, after data processing, by its storageIn program in self-defining structure, and writing in files backs up at local client, afterwards via wireless communication module through currentThe network at place sends. Server has wireless communication module, and server can be chosen specific portable intelligence with eachCan terminal carry out wireless telecommunications. When server listens to the service request of sending from client, network parameter is resolved, comply withAccording to joint radio resource management algorithm, analyze optimum network, and court verdict is fed back to client access, carry out industryBusiness.
The present invention has utilized joint radio resource management technology in heterogeneous network, and by Embedded platform, is intended to improve and movesIt is poor that user network in moving communication is experienced, network congestion, the long problem of business time delay, and utilize wireless network farthestNetwork resource. Client is on the basis of the support of the data that get, by sending service request to server, at serverThe corresponding joint radio resource management algorithm of middle operation, and result is fed back to client, client is selected specified networkAccess finishing service service.
Embodiments of the present invention relate to a kind of multimode terminal intelligent selecting method towards heterogeneous network environment, comprise following stepRapid: mobile terminal support access heterogeneous network, in the time carrying out business, mobile terminal gathers the network of relation ginseng of described businessNumber, and send service request and network parameter to server, the network selection result that monitoring service device postbacks simultaneously; ServerReceive after service request, network parameter is resolved, according to joint radio resource management algorithm, analyze optimum netNetwork, and network selection result is fed back to described mobile terminal; Mobile terminal receives that after network selection result, access network is heldIndustry business.
As shown in Figure 2, multimode intelligent terminal selective system be finally applied in embedded (being specific movable-type intelligent terminal) andTwo platforms of server. Two large major functions of multimode intelligent terminal selective system are communication and decision-making.
Communications portion comprises the multimedia functions such as voice communication, web page browsing, video request program and the biography with business relevant parametersDefeated. Select after access at network, speech business completes by sending AT order in cellular network, in WLANRealize by VOIP. Web page browsing and video request program can be selected by input module, and in terminal, output module entersRow demonstration.
The transmission of network parameter comprises note channel and 2 kinds of transmission modes of socket channel. When user search is carried out to neighbouringConnect server time, in the time of 2G/3G network, by sending AT order by the network information collecting to communication moduleSend to server via short message mode; In the time of wlan network, send to server via socket. Service afterwardsDevice feeds back to client via identical transmitting channel by the result of decision.
Decision making function is decision-making function, and server, according to reconfigurable network, type of service and service priority, is complied withAccording to analytic hierarchy process (AHP), calculate preferred network and alternative network, then taking each offered load as evaluation criteria, select not exceed netThe network of network load threshold accesses.
Be not difficult to find, the present invention can effectively directly help mobile subscriber to make determining of optimal network access for business characteristicPlan, with the efficient utilization of each network of ensuring coverage, the high efficiency of business. The present invention also can be applicable to current multi mode terminal,There is feature easy to carry, mobility is strong.
