Be described below in conjunction with preferred embodiment.
Propose a kind of UE in this preferred embodiment and trigger discovery ANDSF when cellular network LAC switches, and trigger UE network by set of cells and non-3 GPP access network mapping table and be switched to non-3 GPP access network (especially WLAN) from honeycomb Packet Based Network, to improve UE carrying out the promptness of network shunt and the method for availability by ANDSF.Wherein, describe a kind of UE when cellular network switches LAC, the set of cells information of Access Network within the scope of current LAC and coupling is asked to ANDSF, and be switched to preset Access Network (especially WLAN at UE, this preferred embodiment is for WLAN) set of cells that mates time, initiate the method switching attachment, to be switched to the success rate of WLAN in order to improve UE from honeycomb packet network.
This preferred embodiment can realize based on multimode terminal (i.e. subscriber equipment), and necessary precondition is that terminal possesses WLAN (wireless local area network) access capability and mobile cellular network packet domain access capability.Fig. 5 is system architecture diagram according to the preferred embodiment of the invention, and composition graphs 5, for Android platform bimodulus Wi-Fi terminal, this terminal increases session protocol processing module, network shunt module newly to realize this preferred embodiment.
Network shunt module: be mainly used for the real-time cell information by positional information module being provided, the cell information recorded in database module is searched for, if search the set of cells information of coupling, then obtain corresponding focus SSID, and trigger unlatching WLAN switch, search for the focus of above-mentioned SSID, initiate to connect switching.When the real-time LAC information of network shunt module simultaneously for providing in positional information module switches, trigger and find ANDSF process, and obtain effective access network and set of cells mapping table within the scope of current LAC by session protocol processing module from ANDSF, be recorded in database module.This network shunt module achieves the function of above-mentioned search module 32, initiation module 34 and acquisition module.
Session protocol processing module: be mainly used for the safe transmission of carrying out data with the session protocol of ANDSF server (the present invention is for OMA DM agreement) processing module.When upgrading in network shunt module trigger data storehouse, carry out the secure communication of S14 interface with the session protocol processing module of ANDSF server.
Composition graphs 5, the ANDSF in this preferred embodiment needs to increase information analysis module, and improves original session protocol processing module and database module, to realize the function of this preferred embodiment.
Information analysis module: mainly according to the LAC positional information that UE uploads, from database module, obtains the focus under current LAC position and set of cells mapping table, and sends session protocol processing module to.
Session protocol processing module: be mainly used for communicating with the session protocol processing module of Wi-Fi terminal, and process is decrypted to the message that UE uploads, hand to information analysis module, simultaneously the corresponding session protocol processing module information package that information analysis module obtains being issued UE.Achieve the function of above-mentioned receiver module 42 and sending module 44.
Database module: be mainly used in storing Access Network information, comprise static AP position and access information, and this preferred embodiment increases the corresponding set of cells in AP position and LAC information.
Fig. 6 is flow chart according to the preferred embodiment of the invention, is described in figure 6 for Android platform bimodulus Wi-Fi terminal.
After the positional information module of step S602, UE detects that cellular network LAC switches, in a database inquiry switch after LAC whether mate hot spot data time, if not, trigger ANDSF discovery procedure.
Step S604, UE send DHCP inquiry request to ANDSF server, require the IP address or the domain-name information that obtain ANDSF.
Step S606, optionally, UE obtains FQDN(Fully Qualified Domain Name from Dynamic Host Configuration Protocol server), UE sends DNS name resolution request to dns server, obtains the IP address of ANDSF server.
After step S608, UE obtain the IP address of ANDSF, UE and ANDSF sets up secure connection, is carried out the safe transmission of data by S14 interface based on OMA DM.ANDSF network element deployment, in the core net of Cellular Networks, is communicated with terminal by S14 interface, carries out the selection of Access Network according to the information accessory terminal such as positional information and user's network selection preference of terminal to report.S14 interface is an interface realizing on IP layer, and OMA-DM is the implementation of recommending, and this needs network side and end side all to support OMA-DM agreement.Terminal has two kinds: push mode (ANDSF initiatively initiates policy update) and pull mode (UE initiates to network side the renewal that strategy is carried out in request) from the mode of acquisition strategy ANDSF.
Step S610, ANDSF responds the request of UE, the positional information current according to UE returns available access networks (WLAN hot spot and corresponding set of cells (CellID1, CellID2, CellID3 in its LAC coverage ...) mapping table) information, single focus SSID(service set identifier, service set) map multiple cell information, trigger shunting probability to improve.
Step S612, UE, in this LAC coverage, when community switches, search in Hot Spot compound mapping table, and the record searching coupling then obtains its corresponding hot information SSID1.
Step S614, UE open the machine WLAN switch, initiate hot spot scanning, obtain the ssid list under current location, if there is above-mentioned focus SSID1, jump procedure S620.
Step S616, if the focus SSID1 that there is not coupling in WLAN list, then closes Wi-Fi switch, line delay timing of going forward side by side, when arriving timing time t, again attempting, jumping to step S614.
Step S618, optionally, if there is cell merge between time delay, then this time time delay stops, and jumps to step S612.
Step S620, Wi-Fi initiate the operation connecting SSID1, and carry out shunting after successful connection and switch, data traffic is diverted to WLAN link from cellular network.
After above-mentioned flow process completes, by increasing focus and set of cells mapping table, the place intensive in community, UE is completed by ANDSF and is diverted to WLAN from cellular network, reaches the object of assisting UE automatic shunt to WLAN.
