In this step, when UE, which is in roaming state, to be needed to access WLAN, UE can be public according to pre-stored ownership Land mobile network (Home Public Land Mobile Network, HPLMN), the first WLAN operators selection provided What strategy and/or visited Public Land mobile network (Visited Public Land Mobile Network, VPLMN) provided 2nd WLAN operators selection strategy selects WLAN operators.Wherein, Home Public Land Mobile Network network is also referred to as home network Network, visited Public Land mobile network are also referred to as visited network.

In the present embodiment, the priority of the first WLAN operators selection strategy is higher than the 2nd WLAN operators selection strategy Priority, and in the first WLAN operators selection strategy include with HPLMN have WLAN roaming partnership (or roaming cooperate Relationship) operator selection strategy, include in the 2nd WLAN operators selection strategy has WLAN roaming partner pass with VPLMN The selection strategy of the operator of system.Therefore, UE is when selecting WLAN operators, preferentially according to the first WLAN operators selection strategy Selected, when according to the first selected WLAN operators of WLAN operators selection strategy without intercommunication therewith WLAN when, Further according to the 2nd WLAN and selection strategy selection WLAN operators of operator.Since UE and HPLMN have signing, in selection WLAN When, preferential selection and the WLAN that the HPLMN operators for having WLAN roaming cooperative relationship provide are more advantageous to user.

Step 102, according to the WLAN operators of selected intercommunication and WLAN, establish and connect with selected WLAN.

After UE has selected WLAN operators and the WLAN of intercommunication, UE is by selected WLAN to selected The network equipments such as the WLAN operators of WLAN intercommunications send authentication message, establish WLAN connections.

Method provided in this embodiment, UE in roaming during selection WLAN operators, preferentially provided according to HPLMN the One WLAN operators selection strategy is selected, when according to the first selected WLAN operators of WLAN operators selection strategy Without intercommunication therewith WLAN when, further according to the 2nd WLAN and operator selection strategy selection WLAN operators.So that UE is being selected The available WLAN provided with the WLAN operators that belonging area network there are roaming relationships when selecting WLAN is preferentially provided, is realized Influence and control of the 3GPP networks to UE selection WLAN operators, that improves user is successfully accessed rate, is that user is switching and overflowing Better experience is brought during trip, while rate when user roams can be reduced.

Fig. 2 selects the flow chart of WLAN WLAN operators and the embodiment of the method two of WLAN, this reality for the present invention It applies in example, UE first selects WLAN operators, in the WLAN of selection and the intercommunication of selected WLAN operators from available WLAN. As shown in Fig. 2, method provided in this embodiment, includes the following steps：

Step 201, scanning determine available WLAN.

In the present embodiment, UE can first scan determining available WLAN before selection WLAN operators.Specifically, when When UE is in roaming state, it can be scanned by existing WLAN technologies to available WLAN.

Also, UE can also determine the corresponding operators of available WLAN scanned, and specifically, UE can be by holding Row access net vlan query protocol VLAN (Access Network Query Protocol, ANQP) is got pair at accessible WLAN The operator's informaiton answered；Alternatively, UE can also by shift strategy between system (Inter-System Mobile Policy, ISMP WLAN access nets and the fortune) or between system included in routing policy (Inter-System Routing Policy, ISRP) The correspondence for seeking quotient obtains the information of the corresponding operators of available WLAN.Here, the corresponding operators of WLAN both may packet The WLAN operators for having WLAN roaming cooperative relationship with HPLMN are included, also include having WLAN roaming cooperative relationship with VPLMN WLAN operators；Here WLAN operators can be 3GPP operators, for example, 3GPP operators provide simultaneously 3GPP access nets with During WLAN access nets；It can also be non-3 gpp operator, such as be capable of providing the cable network operator or only of WLAN access nets Operator of WLAN access nets etc. is provided.

Step 202, second provided according to HPLMN the first WLAN operators selection strategies provided and/or VPLMN WLAN operators selection strategy selects WLAN operators.

In the present embodiment, the first WLAN operators selection strategy includes operator's priority and operator identifier.Operation It can be domain name identification (domain name), tissue unique mark OUI (Organizationally Unique that trade mark, which is known, Identifier, abbreviation OUI) and/or PLMN marks.Domain name identification can be used for identifying different network domains (realm).OUI Be American Institute of Electrical and Electronics Engineers (Institute of Electrical and Electronics Engineers, Abbreviation IEEE) as defined in different tissues unique mark.When operator is PLMN operators, PLMN can also be used to identify, PLMN is identified by Mobile Country Code MCC (Mobile Country Code, MCC) and Mobile Network Code (Mobile Network Code, MNC) composition.Any one above-mentioned mark may be used to distinguish different operators, its other party can also be passed through certainly Formula identifies, if can unique mark one operator, the present invention limited not to this.

In the present embodiment, the first WLAN operators selection strategy and the 2nd WLAN operators selection strategy are pre-stored in UE In, specifically, UE can obtain the first WLAN operators selection strategy and the choosing of the 2nd WLAN operators by following three kinds of modes Select strategy：

The first：First WLAN operators selection strategy is included in H-ANDSF strategies, is provided by H-ANDSF entities； 2nd WLAN operators selection strategy is included in V-ANDSF strategies, is provided by V-ANDSF entities.After UE access network, UE Can to H-ANDSF entities send request message, for obtain the first WLAN operators selection strategy, H-ANDSF entities according to First WLAN operators selection strategy is carried and is returned in the response message to UE by the request message of UE；Similarly, when UE is overflow When swimming over to access zone network, the 2nd WLAN operators selection strategy can be got from V-ANDSF entities.UE preserve from The first WLAN operators selection strategy and the 2nd WLAN operators selection strategy that ANDSF entities are got, in order to which UE is next When accessing WLAN, it can be selected according to the strategy of preservation.In order to which UE can accurately know that the first WLAN operators select Strategy and the 2nd WLAN operators selection strategy, UE can periodically to ANDSF ask more new operators selection strategy or When ANDSF strategies change, ANDSF timely notifies UE, convenient for UE timely more new operators selection strategies.

Second：First WLAN operators selection strategy manages the HPLMN included in object I-WLAN MO for WLAN intercommunications The WLAN operator lists of control, the 2nd WLAN operators selection strategy are the VPLMN controls included in the I-WLAN MO WLAN operator lists.UE needs to obtain the WLAN operator lists of HPLMN controls and VPLMN controls from I-WLAN MO in advance The WLAN operator lists of system.Wherein, include in the WLAN operator lists of HPLMN controls has WLAN roaming with HPLMN The information of the operator of cooperative relationship, VPLMN control WLAN operator lists in include with VPLMN have WLAN roaming The information of the operator of cooperative relationship, such as the first grade of operator identifier and operator.UE is first controlled in selection according to HPLMN Operator's selective listing of system is selected, when the operation for not having in the available WLAN of scanning discovery and being controlled according to HPLMN During the WLAN of the selected WLAN operators intercommunication of quotient's selective listing, WLAN operators alternative column that UE is controlled further according to VPLMN Table selection WLAN operators.

The third, the first WLAN operators selection strategy be the HPLMN controls that include in Global Subscriber identification module USIM WLAN operator lists, the 2nd WLAN operators selection strategy be USIM in include VPLMN control WLAN operators row Table.In the present embodiment, the WLAN operator lists of user's control are also included in USIM, wherein, the WLAN fortune of user's control The priority of quotient's list is sought higher than the priority of the WLAN operator lists of HPLMN controls and the WLAN operators of VPLMN controls The priority of list.Operation has been respectively included in the operator list of above-mentioned user's control, HPLMN controls VPLMN controls The mark and priority of quotient.

It should be noted that in the present embodiment, when UE does not receive or do not preserve H-ANDSF strategies and V-ANDSF plans Do not preserve slightly or the WLAN operator lists for the HPLMN controls that I-WLAN MO are included and the WLAN operations of VPLMN controls Quotient's list, such as UE has just been switched on or when detecting network signal again after leaving network signal covering, UE can be according to USIM The WLAN operator lists of the user's control included in card, the operator list of the VPLMN controls of HPLMN controls and VPLMN controls The priority of the WLAN operator lists of system carries out the selection of WLAN operators.When UE is after network is accessed, get or in advance First preserve H-ANDSF strategies and V-ANDSF strategy or I-WLAN MO in comprising HPLMN control WLAN operator lists and In the case of the WLAN operator lists of VPLMN controls, operators of the UE preferentially in ANDSF strategies or I-WLAN MO arranges Table selection WLAN operators.

In the present embodiment, UE has pre-saved the first WLAN operators selection strategy and the 2nd WLAN operators selection plan Slightly, UE is selected according to HPLMN the first WLAN operators selection strategies provided and/or VPLMN the 2nd WLAN operators provided Strategy selects WLAN operator UE, specifically includes three kinds of scenes：

The first scene, UE are only selected when selecting WLAN operators according to the first WLAN operators selection strategy. This scene be suitable for UE under non-roaming state either UE in advance without preserve the 2nd WLAN operators selection strategy or Under roaming state, the 2nd WLAN operators selection strategy is preserved, but the 2nd WLAN operators selection strategy does not come into force.Cause This, further includes in the 2nd WLAN operators selection strategy and is used to indicate whether the 2nd WLAN operators selection strategy is only applicable to There is the instruction message of the user equipment of signing with VPLMN, when the 2nd WLAN operators selection strategy of instruction is only suitable in instruction message During for there is the UE of signing with VPLMN, at this moment the 2nd WLAN operators selection strategy does not come into force to the UE for roaming into VPLMN, When selecting WLAN carrier policy, without the concern for the 2nd WLAN operators selection strategy.

Second of scene, UE are only selected when selecting WLAN operators according to the 2nd WLAN operators selection strategy.

The third scene, UE is when selecting WLAN operators, according to the first WLAN operators selection strategy and the 2nd WLAN Operator's selection strategy is selected.Since the priority of the first WLAN operators selection strategy is selected higher than the 2nd WLAN operators The priority of strategy is selected, UE is in selection, first according to the first selection strategy selection operator of WLAN operators, according to first During the selection strategy selection of WLAN operators, selected according to the priority of each operator, first select the WLAN of highest priority Operator, as the not no WLAN with selected highest priority WLAN operators intercommunication in the available WLAN of scanning discovery When, the low WLAN operators of reselection priority further determine whether the WLAN operator low with selected priority The WLAN of intercommunication, until when all WLAN operations commercial city in the first WLAN operators selection strategy does not have the WLAN of intercommunication, then According to the 2nd selection strategy selection operator of WLAN operators.When being selected according to the 2nd WLAN operators selection strategy, And selection is carried out according to the priority height of each operator, which is not described herein again.

Step 203, the first WLAN is selected according to included in the first ISMP included in H-ANDSF strategies or the first ISRP Select strategy and/or, the 2nd WLAN selection strategies included in the 2nd ISMP included in V-ANDSF strategies or the 2nd ISRP, Selection can be with the WLAN with highest priority of selected WLAN operators intercommunications from available WLAN.

H-ANDSF strategies and/or V-ANDSF strategies are preserved in UE, not only includes the first WLAN in H-ANDSF strategies Operator's selection strategy also includes the first ISMP or the first ISRP strategies, and the first WLAN operators selection strategy and first ISMP and the first ISRP is strategy arranged side by side.Correspondingly, the 2nd WLAN operators selection strategy that is included in V-ANDSF strategies with 2nd ISMP or the 2nd ISRP is also strategy arranged side by side.And in the prior art, when UE is in selection PLMN access nets, V-ANDSF ISRP in strategy, higher than ISRP and the priority of ISMP in H-ANDSF strategies, therefore, is selected with ISMP priority in UE During access net, preferential ISRP and ISMP progress access network selection according to V-ANDSF strategies, when V-ANDSF strategies ISRP and During the access net that not can access in ISMP, just according to H-ANDSF policy selections.Therefore, in the present embodiment, by the first WLAN Operator's selection strategy and the first ISRP or the 2nd ISMP are set up in parallel, the 2nd WLAN operators selection strategy and the 2nd ISMP or 2nd ISRP is also set up in parallel rather than operator's selection strategy is included in ISRP or ISMP, so as to make first WLAN operators selection strategy priority is higher than the 2nd WLAN operators selection strategy.

In the present embodiment, include under specified conditions respectively in the first ISMP, the first ISRP, the 2nd ISMP, the 2nd ISRP (such as locality and/or period etc.) preferentially selects the information of the WLAN of access, and specifically, the information of WLAN includes here The information such as priority and the WLAN mark of WLAN, in the present embodiment, WLAN can be an access point of WLAN access nets (Access Point, AP), also referred to as hot spot (Hotspot), WLAN marks can be service set (Service Set Identifier, abbreviation SSID), basic service set identification (Basic Service Set Identifier, abbreviation BSSID) And/or homogeneity activate business set identifier (Homogenous Extended Service Set ID, abbreviation HESSID) etc. come Identify the information of WLAN.

Here, if UE does not support to access net and WLAN transmitting data streams by 3GPP simultaneously, UE is according to ANDSF's ISMP selects WLAN；If UE supports to access net and WLAN transmitting data streams by 3GPP simultaneously, UE can be according to ANDSF's ISRP selects WLAN.

After UE selectes an operator in above-mentioned steps 202, according to the first ISMP included in H-ANDSF strategies or WLAN selection strategies included in first ISRP and/or, in the 2nd ISMP included in V-ANDSF strategies or the 2nd ISRP Comprising WLAN selection strategies, from available WLAN selection can have a highest with selected WLAN operators intercommunications The WLAN of priority.

Wherein, available WLAN includes：Included in WLAN or ISMP or ISRP that UE is scanned and UE scannings are arrived WLAN, in the present embodiment, if not doing specific explanation, available WLAN is primarily referred to as the latter, i.e. it is that UE is scanned and WlAN included in ISMP or ISRP.It will illustrate how UE selects from available WLAN by specific example below It can be with the WLAN with highest priority of selected WLAN operators intercommunications.For example, UE has selected WLAN operations Quotient SP1, the correspondence that net and operator can be accessed by the WLAN included in ISMP or ISRP judge that can SP1 with can be used WLAN intercommunications.Such as available WLAN is WLAN1 and WLAN2, and the priority of WLAN1 is higher than the priority of WLAN2, then Preferentially judge that can WLAN1 with SP1 intercommunications, if WLAN1 cannot need to judge whether WLAN2 can be with SP1 intercommunication with SP1 intercommunications.

It should be noted that UE can also judge whether selected WLAN operators can be with can be used by other means WLAN intercommunications.For example, UE sends access net inquiry (Access Network Query to the available WLAN1 that scanning is arrived Protocol, ANQP) request, the inquiry response that WLAN1 is returned includes the information of the operator of WLAN1, if the WLAN1 returned Operator's informaiton with selection WLAN operators it is different, then illustrate WLAN1 cannot with the intercommunication of selected WLAN operators, if The information of the operator of the WLAN1 of return is identical with selected WLAN operator's informaitons, then illustrates that WLAN1 can be with the fortune of selection Seek quotient's intercommunication.

Above-mentioned UE judges whether selected WLAN operators can be in steps with the step of available WLAN intercommunications It is performed in 201, i.e. UE is further determined available after scanning to available WLAN according to the available WLAN scanned The corresponding operators of WLAN；Alternatively, if UE does not determine the corresponding operators of available WLAN in step 201, in step 203 In, perform above-mentioned UE judges the step of whether selected WLAN operators can be with available WLAN intercommunications.

In the present embodiment, in the WLAN of UE selections and the intercommunication of WLAN operators, there is also three kinds of scenes, corresponding step Scene in 202, the first scene, only the first ISRP in H-ANDSF strategies or the first ISMP selections and selected WLAN The WLAN of operator's intercommunication.Second of scene, only the 2nd ISRP in V-ANDSF strategies or the 2nd ISMP selections with it is selected The WLAN of WLAN operators intercommunication.The third scene, according in the first ISMP included in H-ANDSF strategies or the first ISRP Comprising WLAN selection strategies and V-ANDSF strategies in WLAN choosings included in the 2nd ISMP or the 2nd ISRP that include Select strategy, selection can be with the WLAN with highest priority of selected WLAN operators intercommunications.In this step, true Under the premise of determining operator, during reselection WLAN, it can enable in the 2nd ISMP or the 2nd ISRP included in V-ANDSF strategies Comprising WLAN selection strategies priority higher than being wrapped in the first ISMP or the first ISRP included in H-ANDSF strategies The priority of WLAN selection strategies contained can not also be considered in the first ISMP or the first ISRP that are included in H-ANDSF strategies Comprising the priority of WLAN selection strategies and V-ANDSF strategies in included in the 2nd ISMP or the 2nd ISRP that include The priority of WLAN selection strategies, but comprehensive H-ANDSF strategies and V-ANDSF strategies are selected, selecting can be with institute in the two The WLAN of the highest priority of the WLAN operators intercommunication of selection.

It should be noted that in the present embodiment, after selection WLAN operators, determine mutual with selected WLAN operators During logical WLAN, the selection of WLAN can not also be carried out according to the ISMP or ISRP included in ANDSF strategies.Specifically, such as Fruit UE only preserves operator's selective listing in usim card, and does not preserve ANDSF strategies, then UE is when selecting WLAN, root It is selected according to the priority of available WLAN in USIM cards.Alternatively, only preserve what is included in I-WLAN MO strategies in UE Operator's selection strategy, and ANDSF strategies are not preserved, then UE is wrapped when selecting WLAN according in I-WLAN MO strategies The priority selection WLAN of the available WLAN contained.Above-mentioned two situations are all the prior art, and so it will not be repeated.

Step 204, according to the WLAN operators of selected intercommunication and WLAN, establish and connect with selected WLAN.

Method provided in this embodiment, UE first select operator in the WLAN of selection access, reselection can with it is selected The WLAN of WLAN operators intercommunication selected, when selecting operator, preferential selection has WLAN roaming cooperative relationship with home network WLAN operators, so as to improve user access success rate, promoted user roam and handoff procedure in experience, and And preferential selection has the WLAN of operator's offer of WLAN roaming cooperative relationship with home network, can reduce the roaming money of user Take.

Fig. 3 is the flow chart of present invention selection WLAN WLAN operators and the embodiment of the method three of WLAN；This reality The method for applying example offer is compared with the method in embodiment two, and UE first selects WLAN, and reselection has with selected WLAN intercommunications The WLAN operators of highest priority.As shown in figure 3, method provided in this embodiment, includes the following steps：

Step 301, scanning determine available WLAN.

UE scannings include having WLAN roaming cooperative relationship with home network to available multiple WLAN, available WLAN Operator provide WLAN, also include with visited network have WLAN roaming cooperative relationship operator provide WLAN.UE is also It can determine the corresponding operators of accessible WLAN, specific determining method is referred to implement the description in two.

Step 302, the first WLAN is selected according to included in the first ISMP included in H-ANDSF strategies or the first ISRP Select strategy and/or, the 2nd WLAN selection strategies included in the 2nd ISMP included in V-ANDSF strategies or the 2nd ISRP, WLAN is selected from available WLAN.

In the present embodiment, in WLAN selection strategies and the 2nd ISMP included in the first ISMP or the first ISRP or All include the mark and priority of available WLAN in WLAN selection strategies included in 2nd ISRP.When UE is selected, root According to the high WLAN of the priority selection priority of WLAN.

Specifically, the present embodiment includes three kinds of situations, the first situation, UE is according to included in H-ANDSF strategies WLAN selection strategies included in one ISMP or the first ISRP select WLAN.The second situation, UE is according in V-ANDSF strategies Comprising the 2nd ISMP or the 2nd ISRP included in WLAN selection strategies, select WLAN.The third situation, UE is according to H- It is included in WLAN selection strategies and V-ANDSF strategies included in the first ISMP included in ANDSF strategies or the first ISRP The 2nd ISMP or the 2nd ISRP included in WLAN selection strategies, comprehensive selection WLAN.For the suitable of above-mentioned three kinds of situations It can refer to the description implemented in two with scene, which is not described herein again.

In the present embodiment, emphasis describes the third situation, and UE is identified according to the accessible WLAN scanned, root According in WLAN selection strategies and V-ANDSF strategies included in the first ISMP or the first ISRP included in H-ANDSF strategies Comprising the 2nd ISMP or the 2nd ISRP included in WLAN selection strategies, determine available WLAN, and from available WLAN The WLAN of one highest priority of middle selection.

Step 303, according to HPLMN the first WLAN operators selection strategies provided and/or, VPLMN provide the Two WLAN operators selection strategies, selection can be with the WLAN operators with highest priority of selected WLAN intercommunications.

It needs further to determine WLAN operators after WLAN is determined there are following two situations, the first situation, by May be identical in the priority of multiple WLAN, such as there are three the WLAN of determining highest priority, the operator of each WLAN Difference, therefore also need to further determine optimal operator according to the priority for the operation for providing WLAN.Another situation It is that multiple operators share a WLAN mark, such as two operation commercial cities share a BSSID mark, therefore a WLAN Corresponding Liang Ge operators, it is also desirable to further determine operator.

After selecting WLAN in step 302, need further to select the tool with selected WLAN intercommunications in this step There are the WLAN operators of highest priority.Specifically, three kinds of situations in corresponding step 302, the first situation, UE is according to H- WLAN selection strategies included in the first ISMP included in ANDSF strategies or the first ISRP select WLAN, correspondingly, at this In step, the first WLAN operators selection strategy that is included in the H-ANDSF strategies that UE is provided according to HPLMN determine with it is selected The WLAN operators with highest priority for the WLAN intercommunications selected.

The second situation, UE WLAN according to included in the 2nd ISMP included in V-ANDSF strategies or the 2nd ISRP Selection strategy selects WLAN, correspondingly, in this step, second included in the V-ANDSF strategies that UE is provided according to VPLMN WLAN operators selection strategy determines the WLAN operators with highest priority with selected WLAN intercommunications.

The third situation, UE WLAN according to included in the first ISMP included in H-ANDSF strategies or the first ISRP WLAN selection strategies included in the 2nd ISMP or the 2nd ISRP included in selection strategy and V-ANDSF strategies, comprehensive choosing Select WLAN.Correspondingly, in this step, UE is according to the first WLAN operators selection strategy and V- included in H-ANDSF strategies The 2nd WLAN operators selection strategy included in ANDSF strategies determines preferential with highest with selected WLAN intercommunications The WLAN operators of grade.Since the first WLAN operators selection strategy priority is higher than the 2nd WLAN operators selection strategy, because This, UE when selecting WLAN operators, first according to HPLMN provide the first WLAN operators selection strategy selected, first from There are the WLAN operators that highest priority is selected in the operator of WLAN roaming cooperative relationship with HPLMN, determine selected WLAN operators can with selected WLAN intercommunications, if being unable to intercommunication, the WLAN operators of reselection lower priority, specifically such as What judge selected WLAN can with the intercommunication of WLAN operators, reference can be made to the description in embodiment two.When the first WLAN operators It cannot then be transported with selected WLAN intercommunications according to the 2nd WLAN that VPLMN is provided WLAN operations commercial city in selection strategy Battalion's quotient's selection strategy is selected, and the WLAN operations commercial city that the 2nd WLAN operators selection strategy includes is that have with VPLMN The WLAN operators of WLAN roaming cooperative relationship, likewise, when according to the 2nd WLAN operators selection strategies selection and root It is selected according to the priority of WLAN operators.

It is understood that if the WLAN determined in step 302 is unique, i.e., only there are one run by selected WLAN Quotient provides, then no longer needs to perform step 302.

304th, it according to the WLAN operators of selected intercommunication and WLAN, establishes and connects with selected WLAN.

Method provided in this embodiment, UE first select WLAN in the WLAN of selection access, reselection can with it is selected WLAN intercommunications WLAN operators, when selecting WLAN operators, preferential selection has WLAN roaming cooperation pass with home network The WLAN operators of system so as to improve the success rate of user's access, promote experience of the user in roaming and handoff procedure, And preferentially selection has the WLAN of operator's offer of WLAN roaming cooperative relationship with home network, can reduce the roaming of user Rate.

For above-described embodiment two and embodiment three, the WLAN accessed and the WLAN with selected intercommunication are selected in UE After operator, when establishing WLAN connections, UE sends authentication request message to network side equipment, and net is carried in the authentication request message Network access identifies (Network Access Identifier, NAI), and selected WLAN operators are included at least in the NAI Mark, user name, the mark of the mark of HPLMN and/or VPLMN.If selected WLAN operators are to be carried according to HPLMN The first WLAN operators selection strategy selection supplied, including at least the mark of selected WLAN operators, user in NAI The mark of name and HPLMN.If selected WLAN operators are the 2nd WLAN operators selection strategy choosing provided according to VPLMN It selects, the mark of VPLMN is also included in NAI.Wherein, user name can be international mobile subscriber identity (International Mobile Subscriber Identification Number, IMSI), the mark of WLAN operators The mark of knowledge, the mark of HPLMN and VPLMN route for message, i.e., the choosing of the transmission path of authentication message in authentication process It selects.Specifically, following two forms may be used in NAI：

The first, ' homerealm！Username@otherrealm, wherein, Username (user name) includes UE's IMSI, when using different authentication modes, representation method that user name will be different, according to EAP-AKA authentication modes, The representation of user name is " 0<IMSI>", according to EAP-SIM authentication modes, then user name identification means are " 1<IMSI >".Marks (domain name) of the Otherrealm (other domains) for operator, such as wlan.cablewifi.com；Work as institute When PLMN operators is in the operator selected, homerealm (home domain) is the identification name of HPLMN, such as wlan.mnc015.mcc234.3gppnetwork.org.When HPLMN is unique WLAN roaming partner of the operator of selection When, NAI can not also include otherrealm domains, be expressed as ' username@homerealm '.

Second, ' visitedrealm！homerealm！Username@otherrealm' are compared with the first, more Visitedrealm domains (visit domain), visitedrealm is the mark of VPLMN, such as wlan.mnc071.mcc610.3gppnetwork.org.When UE is in roaming state, and need to connect by home domain network When entering WLAN, need to carry visited realm domains in authentication process.When VPLMN is that the unique WLAN of selected operator is overflow When swimming partner, visited realm domains can not be carried, NAI representations are homerealm！username@ otherrealm'。

It should be noted that in above-described embodiment one to embodiment three, the first WLAN operators selection strategy and second It can also include the effective verification condition of selection strategy in WLAN operators selection strategy, can specifically include：It is tactful effective Region (Validity Area), strategy effective time (TimeofDay), roaming condition for validity (Roaming), local signing Terminal condition for validity.Wherein, tactful effective coverage is used to indicate the effective region of selection strategy, such as：When UE access, according to The positioning methods such as GPS obtain present position, and judge current location whether in effective coverage, if in effective coverage, The selection of WLAN and operator is then carried out using the strategy, when not in effective coverage, then using the strategy of other activation into The selection of row WLAN.The tactful effective time is used to indicate the effective time range of strategy, such as：UE according to it is current when Between judge whether within the effective time, when the strategy is just effective within effective time, UE is just needed according to the tactful progress WLAN and the selection of operator.Roaming condition for validity is used to indicate whether the strategy when UE is roamed comes into force.Local signing is eventually End condition for validity is used for representing whether the rule only comes into force to the UE with the signing for the PLMN for providing the strategy, such as： During forHomeSubscribedUE=1, which only comes into force to the UE with the signing for the PLMN for providing the strategy, that is, only has When the PLMN for providing the strategy is the HPLMN of UE, which just comes into force to UE；During forHomeSubscribedUE=0, the rule It then all comes into force to all UE, that is, the PLMN for providing the rule is the HPLMN or VPLMN of UE, which all comes into force.Foundation This parameter, UE may determine whether the operator's selection strategy provided using VPLMN.

By setting multiple effective verification conditions of strategy so that UE can at different conditions (such as different location or when Between section), select optimal WLAN and WLAN operators.

Fig. 4 selects the flow chart of WLAN WLAN operators and the embodiment of the method four of WLAN, this reality for the present invention It applies example and roaming state is in UE, the first WLAN operators selection strategy included in H-ANDSF strategies is pre-saved in UE The 2nd WLAN operators selection strategy included with V-ANDSF strategies, specifically includes following steps：

Step 401, scanning determine available WLAN.

UE can also determine the corresponding operators of available WLAN after the available WLAN scanned, and specifically determining can The specific method of the corresponding operators of WLAN can be found in the description of step 201 in embodiment two, and which is not described herein again.

Step 402 selects N priority according to the first WLAN operators selection strategy included in H-ANDSF strategies WLAN operators.

Include the WLAN operators that there is WLAN roaming cooperative relationship with HPLMN in first WLAN operators selection strategy Mark and priority.When UE selects WLAN operators, first choosing has the WLAN operators of highest priority.In the present embodiment, N Represent the priority with the HPLMN WLAN operators with WLAN roaming cooperative relationship, initial value 1 represents priority most It is high.The value of N is bigger, represents that priority is lower.

Whether step 403 judges to include in the ISMP or ISRP that include in H-ANDSF strategies and V-ANDSF strategies and the The WLAN of N priority WLAN operators intercommunication.

In this step, if the determination result is YES, then step 404 is performed；If judging result is no, step 405 is performed.

In this step, UE according in step 402 determine N priority WLAN operators, judge H-ANDSF strategies and Whether comprising available with the WLAN operators intercommunication of N priority in the ISMP or ISRP that are included in V-ANDSF strategies WLAN.Specifically, in H-ANDSF strategies comprising including the 2nd ISMP and the in the first ISRP or the first ISMP, V-ANDSF strategy Two ISRP include the mark and priority of WLAN in ISRP and ISMP, further judge which WLAN can with it is selected The intercommunication of WLAN operators, specifically, UE according to the WLAN scanned in step 401 further judge WLAN whether can be used and It determines the corresponding operators of available WLAN, then judges which can be with the intercommunication of selected WLAN operators in available WLAN. If UE does not determine the corresponding operators of available WLAN in step 401, UE determines that available WLAN whether can in this step Enough and selected WLAN operators intercommunication, may refer to the description of step 203 in embodiment two.

It is illustrated below, if the WLAN operators of the highest priority selected in step 402 are SP1, according to H-ANDSF The priority of available WLAN is determined in the ISMP or ISRP that are included in strategy and V-ANDSF strategies, then according to available WLAN and corresponding operator's informaiton judge which WLAN can be with SP1 intercommunications.Such as available WLAN is：WLAN1、 WLAN2, WLAN3, according to the ISMP or ISRP included in H-ANDSF strategies and V-ANDSF strategies, priority is： WLAN1 Prior to WLAN2, WLAN2 prior to WLAN3；The operator of WLAN1 is SP1, and the operator of WLAN2 is SP1, then understands WLAN1 and WLAN2 can be with SP1 intercommunications.

It should be noted that in this step, if according to the ISMP included in H-ANDSF strategies and V-ANDSF strategies or The not no WLAN with SP1 intercommunications in ISRP, but other available WLAN for scanning in step 401 of UE can with SP1 intercommunications, Such as WLAN4, WLAN4 are not included in ISMP or ISRP, but WLAN4 can be with SP1 intercommunications, optionally, UE can also be selected WLAN4 establishes connection, and subsequent step no longer performs.

Step 404, the WLAN that highest priority is selected from the WLAN of the WLAN operators intercommunication of N priority, build Vertical WLAN connections.

After having performed this step, subsequent step is no longer performed.

If judge there are multiple WLAN can be with the WLAN operators intercommunication of N priority, this step in step 403 The middle priority according to each WLAN selects the WLAN of a highest priority as the WLAN being currently accessed, and establishes WLAN Connection.If only there are one WLAN to be not required in this step with the intercommunication of N priority WLAN operators for step 403 judging result It is selected, directly establishes WLAN connections.

Step 405, judge whether to include in the first WLAN operators selection strategy included in H-ANDSF strategies it is relatively low The WLAN operators of priority if so, N adds 1, return and perform step 402, if it is not, performing step 406.

When the judging result of step 403 is no, this step is performed, i.e., can not be runed with the WLAN of highest priority Whether the WLAN of quotient's intercommunication then judges to include in the first WLAN operators selection strategy included in H-ANDSF strategies relatively low The WLAN operators of priority, in this step, when judging result adds one for N in the case of being, return performs step 402, i.e., The WLAN operators for having priority relatively low in first WLAN operators selection strategy then select preferential from remaining WLAN operators The highest WLAN operators of grade, i.e. the priority N of WLAN operators add 1, return and perform step 402, continued to determine whether with Priority adds the WLAN of 1 WLAN operators intercommunication for N.If judging result is no, step 406 is performed.

Step 406 selects M priority according to the 2nd WLAN operators selection strategy included in V-ANDSF strategies WLAN operators.

In step 405 judging result to perform this step in the case of no, i.e., in H-ANDSF strategies and V-ANDSF strategies Comprising ISMP or ISRP in all not can with the WLAN of selected WLAN operators intercommunications, then according to V-ANDSF strategies In the WLAN operators of the 2nd WLAN operators selection strategies selection M priority that include.In second operator's selection strategy Include the mark and priority of the WLAN operators with VPLMN with WLAN roaming cooperative relationship.M expressions have with VPLMN The WLAN operators priority of WLAN roaming cooperative relationship, initial value 1, i.e. highest priority.The value of M is bigger, represents preferential Grade is lower.

Whether step 407 is judged in H-ANDSF strategies and ISMP or ISRP in V-ANDSF strategies comprising preferential with M The WLAN of the WLAN operators intercommunication of grade.

If the judging result of this step is yes, i.e., wrapped in H-ANDSF strategies and ISMP or ISRP in V-ANDSF strategies WLAN containing the WLAN operators intercommunication with M priority, then perform step 408, and specific judgment method can refer to step 403.If the judging result of this step is no, i.e., do not include in H-ANDSF strategies and ISMP or ISRP in V-ANDSF strategies With the WLAN of the WLAN operators intercommunication of M priority, step 409 is performed.

Step 408, the WLAN that highest priority is selected from the WLAN of the WLAN operators intercommunication of M priority, build Vertical WLAN connections.

After this step has been performed, subsequent step is no longer performed, terminates flow.

Step 409, judge whether to include in the 2nd WLAN operators selection strategy included in V-ANDSF strategies it is relatively low The WLAN operators of priority if so, M adds one, return and perform step 406, if it is not, terminating flow.

The judging result of this step is yes, i.e., is wrapped in the 2nd WLAN operators selection strategy included in V-ANDSF strategies WLAN operators containing lower priority then select the WLAN operators of highest priority, then from remaining WLAN operators The priority M of WLAN operators adds one, returns and performs step 406, further determines whether to add 1 WLAN for M with priority The WLAN of operator's intercommunication.If judging result is no, i.e., the 2nd WLAN operators selection strategy that is included in V-ANDSF strategies In do not include and have the WLAN operators of lower priority, then terminate flow.

Fig. 5 selects the flow chart of WLAN WLAN operators and the embodiment of the method five of WLAN, this reality for the present invention It applies example and roaming state is in UE, the first WLAN operators selection strategy included in H-ANDSF strategies is pre-saved in UE It is illustrated for the 2nd WLAN operators selection strategy included with V-ANDSF strategies, specifically includes following steps：

Step 501, scanning determine available WLAN.

Specific method can be found in the description of step 201 in embodiment two.

Step 502, according to the ISMP or ISRP that include in H-ANDSF strategies and V-ANDSF strategies, select M priority Available WLAN.

Specifically, such as in step 501 it scans to three accessible WLAN, and ISMP or ISRP include four WLAN, and the three accessible WLAN scanned are included in ISMP or ISRP, so priority in three WLAN of selection Highest WLAN.In the present embodiment, M represents the priority of WLAN, and M initial values are 1, represent highest priority.The value of M is bigger, Represent that priority is lower.

Step 503, judge selected by the WLAN of M priority whether can be with the first WLAN that is included in H-ANDSF strategies Operator's intercommunication of N priority in operator's selection strategy.

In the present embodiment, N represents the priority with the HPLMN WLAN operators with WLAN roaming cooperative relationship, initially It is 1 to be worth, and represents highest priority.The value of N is bigger, represents that priority is lower.Specific judgment method can refer in example IV Description, which is not described herein again.In this step, if the determination result is YES, step 504 is performed；If judging result is no, step is performed 505。

It is step 504, preferential according to the WLAN of selected M priority and with the N of the WLAN intercommunications of M priority The WLAN operators of grade, establish WLAN connections.

After this step has been performed, subsequent step is no longer performed.

Step 505, judge whether to include in the first WLAN operators selection strategy included in H-ANDSF strategies it is relatively low The WLAN operators of priority if so, N adds 1, return and perform step 503, if it is not, performing step 506.

When the judging result of this step is in the case of being, i.e. has priority relatively low in the first WLAN operators selection strategy WLAN operators, then from remaining WLAN operators select highest priority WLAN operators, i.e., WLAN operators is excellent First grade N adds 1, returns and performs step 503, judge selected by M priority WLAN whether can add with priority as N 1 WLAN Operator's intercommunication.

Step 506 judges whether the WLAN of M priority can run with the 2nd WLAN included in V-ANDSF strategies The WLAN operators intercommunication of K priority in quotient's selection strategy.

In this step, if the determination result is YES, step 507 is performed；If judging result is no, step 508 is performed.Wherein, K It represents the priority of the WLAN operators in the 2nd WLAN operators selection strategy, i.e., is closed with VPLMN with WLAN roaming cooperation The priority of the WLAN operators of system, initial value 1 represent highest priority.The value of K is bigger, represents that priority is lower.

It is step 507, preferential according to the WLAN of selected M priority and with the K of the M priority WLAN intercommunications The WLAN operators of grade, establish WLAN connections.

After performing this step, subsequent step is no longer performed, terminates flow.

Step 508, judge whether also to include in the 2nd WLAN operators selection strategy included in V-ANDSF strategies compared with The WLAN operators of low priority if so, K adds 1, return and perform step 506, if it is not, performing step 509.

In this step, if the determination result is YES, i.e., in the 2nd WLAN operators selection strategy included in V-ANDSF strategies Include the WLAN operators of lower priority, then the WLAN operators of highest priority selected from remaining WLAN operators, That is the priority K of WLAN operators adds 1, returns and performs step 506, the WLAN of M priority selected by judgement whether can with it is excellent First grade adds 1 WLAN operators intercommunication for K.

Step 509, judge in the ISMP or ISRP that include whether to include in H-ANDSF strategies and V-ANDSF strategies compared with The WLAN of low priority if so, M adds 1, is returned and is performed step 502, if it is not, terminating flow.

In this step, if the determination result is YES, even the first WLAN operators selection strategy and the choosing of the 2nd WLAN operators The WLAN operators not included in strategy with the WLAN intercommunications of M priority are selected, then from H-ANDSF strategies and V-ANDSF plans The WLAN, i.e. the priority M of WLAN of highest priority are selected in the remaining available WLAN included in ISMP or ISRP slightly Add 1, return and perform step 502, further judge whether there is with priority the WLAN operators for the WLAN intercommunications for adding 1 for M.
