Embodiment
With reference to Fig. 1, network selecting relates to following two parts:
● WLAN inserts the district and selects
● visited network (for example, PLMN) is selected
Wlan network inserts the district and selects and can followingly operate:
UE always attempts at first directly to be connected with home network, and this home network is a Home PLMN 4, and it comprises the attaching position register (HLR) of UE.If home network is unavailable, then UE attempts to connect via preferred backbone network.The selection of backbone network can be that the user assists automatically, and subscriber equipment is implored, or finishes by hand by the user of UE.SSID is illustrated as arrow SSIDPLMN1 and SSID PLMN2 from visited PLMN 1 with 3 to communicating by letter of visited PLMN 2, and they are sent to visited PLMN 2.Visited PLMN 2 sends to WLAN access district with the identity SSID of visited PLMN 1 and PLMN2.And the SSID identity of PLMN3 is directly transferred to WLAN and inserts the district.The transmission to WLAN access district of SSID can directly be finished.Each visited PLMN s 1-3 and Home PLMN 5 have Access Layer AS.
Be delivered to UE by WLAN AP with the form of WLAN SSID about the information of available backbone network.
UE can be mapped to backbone network with each SSID.So UE can select its expectation to be connected to which available backbone net.[this selection can be automatically, and is that the user assists or the user manually finishes.] after selecting, UE utilizes and the corresponding SSID of selected backbone network and related such as the Access Network of visited PLMN 2.
In the appointment of country and/or network type, SSID can use " asterisk wildcard ".Asterisk wildcard represents to select to have any network of one group of characteristic in the characteristic, as country or the network type in one group of a particular type country or the group network.For example, this appointment can be " any 1 type PLMN in the Finland ", and wherein, PLMN type and country code are fixed, but mobile network code, MNC replaced by asterisk wildcard, and it specifies any mobile network.In textual form, " asterisk wildcard " can be various characters, for example "? " "+" or " * ", they have the asterisk wildcard of negotiation and specify meaning, make their use can replace having the network of characteristic indicative character, specify indication, any country and/or any network in a group network of the operable particular type of particular country as country and/or network type.For example, country code can substitute with asterisk wildcard, is illustrated in " any Orange PLMN " of any country to indicate this SSID.
Access Network (visited PLMN 2 of signal) will connect based on selected SSID and further be routed to correct backbone network, as visited PLMN 1 or Home PLMN s 4 or 5.For example, for each SSID relevant, can utilize tunneling technique to transmit all data between Access Network and the backbone network with backbone network.Therefore, the Route Selection of round backbone network can be considered to the tunnel mapping.The tunnel for example can be, gre tunneling, and virtual lan, L2TP, special-purpose the 3rd layer connects or any other similar transmission mechanism.
In a further exemplary embodiment, each SSID relevant with backbone network can be transformed to authentication automatically, authorize and record keeping (AAA) domain name, as the dialing of the remote authentication in the client server (RADIUS) domain name, or the DIAMETER domain name of the aaa server in the sensing backbone network.This domain name entity is present in visited PLMN s 1-3 and Home PLMN 5 is acted on behalf of as AAA.In the example below, RADIUS is used as the AAA method of example.
When UE had selected SSID, UE created the RADIUS field from selected SSID, and the end of this field being added to the user identity that meets network access identifier (NAI) form.Because the user identity of link meets the NAI form, this authentication at first is routed to selected backbone network.Backbone network is peelled off this link part from original NAI, and this signaling further is forwarded to UE wishes at least one complementary network of being connected to, as from visited PLMN 2 to visited PLMN 1 and the connection of one of Home PLMN s 4 or 5.
1. the use of identifier
A., the SSID value is set
1. the SSID that is used for the PLMN backbone network:
If PLMN is used for the backbone network that WLAN inserts the district, the SSID that then points to this PLMN is passable, for example, follows following form:
[reserved word that is used for the network SSIDs of PLMN type] [version number] [MCC] [MNC] [free text]
Wherein
● the reserved word that is used for the network SSIDs of PLMN type comes such SSID and other SSID difference
● version number makes and can change form in the future
● mobile country code (MCC) is the PLMN country code
● mobile network code, MNC (MNC) is the PLMN network code
● free text can be used for, and for example, indicates user-friendly network title
The actual content of ssid field can with advise above different, and indicated content is just hoped as an example how realizing ssid field configuration.
2. the SSID that is used for non-PLMN backbone network:
If backbone network is not PLMN, the SSID that then points to this network can be following form:
[reserved word that is used for the network SSIDs of non-PLMN type] [version number] [network title]
Wherein
● the reserved word that is used for the network SSIDs of non-PLMN type comes such SSID and other SSID difference
● version number makes and can change form in the future
● network name is called the title of backbone network
The actual content of SSID information field can change, and indicated content just hopes as an example how realizing ssid field configuration, and without any restriction.
The configuration of II.SSID
A. the national WLAN roaming between the backbone network
If backbone network and another are not directly connected to the backbone network of same WLAN AZ national roaming agreement is not arranged, then:
● there is not the supplier of connected backbone network that its SSID can be provided for the supplier of connected backbone network
● connected backbone network can be revised its SSID and roam into any national SSID that roams the reception of partner network that WLAN inserts district (AZ).
The SSID that WLAN AP can be supported all stores in the interior ssid list of WLAN AP.
B. the WLAN that shares inserts the district:
All SSID that have all backbone networks of interconnection agreement to provide with it by WLAN AZ supplier can be provided the WLAN AZ that shares, so that WLAN to be provided access service.
The SSID that WLAN AP can be supported all stores in the interior ssid list of WLAN AP.
Can followingly give UE with the SSID information delivery:
In the 802.11b beacon frame, WLAN UE receives only beacon SSID.This SSID can be above-mentioned form, and the backbone network that therefore can be used for UE is selected.UE also can store preferred network based on Broadcast SSIDs, is used to promote ready-made related with network.
If UE supports the effective scanning of SSID information, then UE can begin scan available networks with preferred sequence.
At first, UE can scan its Home PLMN SSID.If from the response of WLAN AP, then WLAN UE can not begin to scan preferred roaming partner.For the ease of guessing available roaming partner, UE can guess its residing country.
Can do following thing:
● UE may always suppose at first that it is in its home country, thus the roaming SSID of scanning country
● UE can store the country of frequent access, and uses this information to be used to select the SSID that will scan
● bimodulus UE can check appended cellular network and use this information to be used to select the SSID that will scan
● UE can ask the user to indicate WLAN UE which country is positioned at
But ● the SSID that the scanning of UE random start is available
WLAN UE also can use asterisk wildcard when searching for suitable SSID.For example, WLANUE can ask to comprise the availability of SSID that the specific character string of any character string is followed in the back.WLAN UE also can ask WLAN AP to indicate the SSID of all supports.
Select a WLAN Access Network (AN)
UE can select WLAN AN based on signal strength signal intensity with based on the availability of Home PLMN or preferred key roaming network SSID.
Home network PLMN ID can derive from user's international mobile subscriber identity (IMSI) that SIM or USIM obtain.
Be the PLMN preference lists of selecting preferably to roam PLMN, can use to be stored among SIM or the USIM.
Select backbone network and store by UE
The UE that network enabled is selected can realize selecting automatically and/or by hand of roaming network.The sign of roaming network can send to UE from wireless access network and be used for storage, and can respond subscriber equipment imploring the sign roaming network.The sign of roaming network can be included in according in a of IEEE802.11 and the b services sets identifier partly.
By UE user ID NAI field part is set
Before sending extendible authentication protocol (EAP) identity response, UE can select the backbone network that will connect.
If UE does not support this feature, then UE utilizes its home network field, and depends on that specific implementation determines the RADIUS Route Selection towards the identity of Home PLMN AAA acting server.
If WLAN UE supports roaming network to select, then UE can select WLAN AN the user can be directed to which available backbone net.The result of this selection can show below in the field part that is utilized:
Be not the original user ID that home network distributed:
〔userid〕@〔homeASrealm〕,
UE can utilize the following user ID in the EAP identity response:
The selected backbone network SSID of (userid) (homeASrealm) .[]. (OWLAN.ORG)
Act on behalf of the RADIUS Route Selection of carrying out by network Radius
The radius proxy of user NAI above receiving checks from their " RADIUS routing table " whether message is transmitted.This Route Selection is based on " highest significant position " in this field, that is, according to [the selected backbone network SSID] that insert. (OWLAN.ORG) part.
When inserting request, RADIUS arrives by [selected backbone network SSID]. and during the radius server of (OWLAN.ORG) field sign, radius server is peelled off the part of being inserted, and carries out user's authentication based on remaining NAI.
Perhaps, UE can be independent of backbone network and select, and always utilizes its home network NAI as its user identity.In the case, WLAN UE indicates selected SSID when being connected to this Access Network.Access Network then will connect and further be routed to the backbone network relevant with the SSID that is utilized.This can, for example, be accompanied by the pre-configured tunnel between Access Network and each backbone network.
The subscription authentication of carrying out can still relate to AAA roaming (agency) or MAP (MAP) roams into the user attaching network.Yet this further roaming is not subjected to new PLMN to select the influence of feature.
The invention provides a kind of by using ssid field how to provide PLMN-ID the mechanism of (sign mobile operator network) to UE.
When PLMN ID was included in the ssid field, the cellular network selection may be used for the public's wlan network with the cellular system interconnection.This makes realize global scalability and to the automatic network selection of WLAN.
Utilize the present invention, PLMN ID is comprised in the ssid field, and permission identifies by the PLMN id information of the network selecting that is used for UE or its user of visit UE.
If UE comprises selected SSID, wherein between UE and home network, has the EAP signaling, then home network has and checks whether WLAN AZ and roaming partner have followed the UE network selecting and do not had route that this is connected to the ability of network, and for example, the partner gives the highest roaming charges for roaming.The source of the PLMNID that the SSID that home network can relatively insert from UE derives and the authentication request of reception, if do not match, WLAN Access Network or roaming partner are confirmed as incorrect running.
