Abstract
The invention relates to a method of acquiring user specification in hybrid system, which mainly includes the following steps: a network access service obtains terminal access type, sends authentication request to AAA and adds access type attribute with terminal identification in authentication request information; AAA deploys the user specification relevant to terminal access type, acquires corresponding user specification according to the access type carried by user mark and the authentication request information and delivers to network access server. In the situation of intercommunication between the hybrid network (such as: 3GPP2 or 3 GPP) and other networks, the invention can flexibly deploy the user specification and deploy with different Qos or accounting strategy for the same business by different access types or for different businesses by the same access type (such as directly access to INTERNET by WLAN or access to the business provided by 3GPP2).
Description
Technical field
The present invention relates to the network interworking technology, relate in particular to a kind of method of in heterogeneous system, obtaining user specification.
Background technology
Present third generation partnership projects 2 (Third generation Partnership Project 2; Code division multiple access system (Code Division Multi Access is worked out in organizing 3GPP2); CDMA) network (as: standard that wireless local access network (Wireless Local AccessNetwork, WLAN) etc.) carries out intercommunication of network and other access styles.The characteristics of cdma network are that functions such as scope covers extensively, authentication and accounting are very ripe; It is little that wlan network has area coverage, and cost is low, and the characteristics of high bandwidth and high rate services can be provided.The perfect authentication and accounting that both intercommunications make wlan network can utilize cdma network to provide is machine-processed; Enjoy the business that cdma network provides; Cdma network can utilize wlan network to cover and replenish covering as its focus on the other hand, shares the subnetwork load through wlan network.The user then can enjoy the wide and wlan network two-forty of cdma network scope, service cheaply simultaneously.Therefore no matter be to consider from operator or from user's angle, it all will be the future network Development Trend that many nets merge.
For each contracted user; The capital is at network side RADIUS authentication, mandate, charging (Authentication; Authorization, Accounting AAA) preserves a user specification (user profile) information in the server; The user is to the network side authentication time; The RADIUS aaa server finds user specification (user profile) information according to ID, makes authentication and authorization by the parameter in user specification (user profile) information, and in authentication response, issues the user specification information that needs.Quality of services for users (Quality of service, the key information that QoS) specification (QoS profile), the user business information of contracting is relevant with safety, charging corresponding strategies etc. have been comprised in user specification (user profile) information.
In CDMA and WLAN mutual model, as shown in Figure 1, following three kinds of terminal traffic access modes are arranged, and, defined a kind of mode in the standard at present and can let AAA know user's access style for different access modes.
Mode 1: the terminal is through CDMA Access Network, group data service node (Packet DataServing Node; PDSN) visit the business that CDMA packet domain (packet data service) provides, (Home AAA H-AAA) initiates (if the terminal is positioned at visit ground authentication section to ownership place AAA by PDSN; Then via visit ground AAA (Visit AAA; V-AAA), middle AAA (BrokerAAA, B-AAA) transparent transmission).In 3GPP2 standard x .S0011-D, defined the authentication at terminal under this mode and obtained the userprofile flow process, shown in Fig. 2 A.
Mode 2: Internet is directly visited through the WLAN Access Network in the terminal, and authentication section is initiated (if the terminal is positioned at visit ground, then via V-AAA, B-AAA transparent transmission) by WLANAN to H-AAA.In X.S0028-100, defined terminal authentication flow process under this mode, shown in Fig. 2 B.
Mode 3: the terminal is through WLAN Access Network, grouped data interconnect function (Packet DataInterworking Function; PDIF) visit the business that CDMA packet domain (packet data service) provides; Authentication section is initiated (if the terminal is positioned at visit ground to H-AAA by PDIF; Then via V-AAA, the B-AAA transparent transmission).In X.P0028-200, defined terminal authentication flow process under this mode, shown in Fig. 2 C.
In above-mentioned three modes, adopted radius or diameter agreement to carry out user's authentication, at this moment all (Network Access Service NAS), is the client of H-AAA as network access server for PDSN, WLAN AN, PDIF.H-AAA carries out authentication and authorization according to the parameter in the user specification to the user, and in authentication response, H-AAA returns required user specification (userprofile) to NAS.
The above-mentioned mode of the access style that AAA knows the user that can let is: the 3GPP2 network system has defined a NAS-PORT-TYPE attribute in the Access-Request message of radius (Rfc 2865) or diameter (Rfc 4005); This attribute is used in request message, indicating the physics access style of NAS; At internet numbers distributor gear (Internet Assigned Numbers Authority; IANA) definition of having expanded this attribute in is (referring to IANA; " RADIUS Types "), wherein, the definition relevant with the present invention comprises:
5 virtual；
19 Wireless-IEEE?802.11；
22 Wireless-CDMA2000；
23 Wireless-UMTS；
24 Wireless-1X-EV。
According to the definition among X.S0011-D, X.P0028-100 and the X.P0028-200 among the 3GPP2, the NAS-PORT-TYPE value under above-mentioned three kinds of modes is respectively:
Mode 3 times is 5, shows to be being connected on transport layer by the terminal with PDIF at this moment; The Packet Service that 3GPP2 provides need be visited in the terminal at this moment; But insert through non-3GPP2,, set up a tunnel between terminal and the PDIF earlier based on IKEV2 such as WLAN, WIMAX etc.At this moment the real access style of identification terminal of H-AAA.
This shows, still have drawback in the above-mentioned prior art:
1, to different access style; Should preserve a plurality of different user specifications of user (user profile) at H-AAA; Because the difference of access way may cause the different of QoS specification (QoS profile) and charging policy, wildcard and authentication mode etc.; And type of service and access style increase now; Possible operator hopes can only have certain access technology to provide to some business, but does not dispose different user specification (user profile) with mutual model to the user to different access models among the H-AAA at present.
2, for visit the professional situation of 3GPP2 through other non-3GPP2 access waies, at this moment H-AAA can only know it is that " virtual " inserted (value that shows access style is 5=virtual), and can not discern the concrete access style at terminal at this moment.Cause H-AAA not remove to issue different user specification (user profile) like this and give NAS according to the different access way in terminal.Such as, when 3GPP2 network and WLAN/WIMAX pass through interconnection entities PDIF interconnection, then AAA can't be known concrete access style in verification process.
The problems referred to above do not exist only in the scene of 3GPP2 and WLAN intercommunication, have same problem when 3GPP and WLAN intercommunication yet.
Summary of the invention
In order to solve the defective that exists in the above-mentioned prior art; The present invention proposes a kind ofly to go to distinguish the method for obtaining the different user specification to different access styles; The H-AAA that has solved 3GPP2 under various mutual models (or 3GPP) can both obtain the access style at terminal, and identical ID is issued the technical problem of different user specifications (user profile) according to different access styles and mutual model.
Technical scheme of the present invention is: a kind of method of in heterogeneous system, obtaining user specification; Comprise the following steps: in the authentication access procedure when CDMA network and various Access Network intercommunication; Network access server obtains the access style at terminal; Initiate authentication request to AAA, in authentication request message, increase the attribute of the access style that carries marking terminal; The user specification that the AAA configuration is relevant with the terminal access style, the access style according to carrying in ID and the said authentication request message obtains corresponding user specification, and is issued to network access server; Wherein, the attribute of the access style of said marking terminal is relevant with the NAS-PORT-TYPE attribute.
Wherein, the attribute of the access style of said marking terminal identifies the concrete access style of original NAS-PORT-TYPE attribute when being 5=virtual in said authentication request message, increasing an attribute.Said AAA confirms user mode access and Operational Visit mode through ID, NAS-PORT-TYPE attribute, newly-increased attribute, and is issued to network access server according to the corresponding user specification of these values index in database.
In addition, the attribute of the access style of said marking terminal also can be in existing NAS-PORT-TYPE, to increase to expand and identifies access style, and this expansion comprises with two digits representes concrete access style, such as:
Represent virtual with wireless 802.11 with 40;
Represent virtual with wireless 802.16 with 41;
Represent virtual with wireless CDMA2000 with 42;
Represent virtual with wireless UMTS with 43;
At this moment, AAA removes the corresponding user specification of index and is handed down to network access server according to ID in the authentication message and NAS-PORT-TYPE.
Wherein, said user specification comprises QoS, authentication mode and wildcard, charging policy and type of service can be provided.
Wherein, said network access server is WLANAN server, PDSN server or PDIF server.
Wherein, when said network access server was PDIF, this PDIF obtained the access style at terminal through static configuration or differentiation different protocol implementation.When PDIF obtains the access style at terminal through static configuration; When inserting at the terminal; Different Access Networks is given the IP address of terminal distribution different segment; Corresponding relation in PDIF between the configuration of IP network segment and the access device, in the process of terminal and PDIF built tunnel, PDIF judges access device type and sign according to the IP address at terminal.
Authentication access procedure when in addition, method of the present invention is applicable to CDMA network (comprising 3GPP2,3GPP etc.) with various Access Networks (for example WLAN, WIMAX etc.) intercommunication.
Beneficial effect of the present invention is: at CDMA network (as: 3GPP2,3GPP etc.) and other networks (various Access Networks; Like WLAN, WIMAX etc.) under the situation of intercommunication; Can accomplish flexible configuration user specification (user profile); For going to visit identical business through different access waies, or can both dispose different QoS or charging policy etc. through identical access different service (such as directly visit the business that INTERNET or visit 3GPP2 provide through WLAN).

Embodiment
Core content of the present invention is: in heterogeneous system; For example in the 3GPP2 network system; When NAS (PDIF, WLANAN, PDSN etc.) initiates registration to AAA, also bring the access style at terminal up, for the situation of mode 3 in the above-mentioned prior art; Pass through the interconnection entities in the 3GPP2 network by different access networks; When AAA initiates access authentication, is 5=virtual except in existing authentication request message Radius Access-request or Diameter Access-request, carrying NAS-PORT-TYPE such as the functional entity of PDIF, expands an attribute more in addition; For example: 3GPP2Vendor-Specific Attributes (VSA) attribute, in order to identify access style concrete under this interconnected model.
Need to prove, different heterogeneous systems, the attribute of increase is also inequality, for example when 3GPP system and other network interworkings, increase be 3GPP VSA attribute; And when 3GPP2 system and other network interworkings, increase then be the 3GPP2VSA attribute.Here be that example describes only with the 3GPP2 system.
In the 3GPP2 system, be in 3GPP2 X.P0028-20 05.10.1, to increase a 3GPP2VSA, concrete definition is described below:
InterWorking-type VSA: the access style when identifying non-3GPP2 Access Network through interconnection entities visit 3GPP2 network, only effective when NAS-PORT-TYPE is 5=vitrual, this attribute appears in the authentication request message.Please refer again to following table, it is the concrete definition of this newly-increased attribute " InterWorking-type VSA ":
Wherein:
Type：26
Length：12
Vendor-ID：5535
Vendor-Type：xxx
[0053]?Vendor-Length：6
Vendor-Vlaue：
[0055]?1：wireless?802.11
2：wireless?802.16
3：UMTS
Here just illustrate, do not limit its representation, all the other possible values are not done specific descriptions.
Above-mentioned newly-increased attribute has been arranged, and AAA can learn the concrete access style at terminal when NAS-PORT-TYPE is 5=virtual.
Please with reference to following table, it has added the situation of " InterWorking-type " in the radius attribute tabulation that in X.P0028-2005.10.2, has defined again:
Next; As shown in Figure 3; Can the flexible configuration user in the customer data base of AAA with insert relevant different user specification (user profile); After AAA receives Radius access-request or Diameter access-request message,, in database, index user's user specification (user profile) according to ID and NAS-PORT-TYPE, INTERWORKING-TYPE (effective when the NAS-PORT-TYPE=5); Wherein comprised information such as the QoS that access style is correlated with, charging policy, be issued to then among the corresponding N AS (WLANAN, PDSN, PDIF etc.).
See also Fig. 3 again; AAA at first judges the access style at terminal according to NAS-PORT-TYPE; For example, when NAS-PORT-TYPE was 19, access style was Wireless-IEEE 802.11; AAA is judged as WLANAN and directly inserts, and then AAA is issued to WLAN with the user specification under its this kind access way that in database, indexes; When NAS-PORT-TYPE was 22, access style was Wireless-CDMA2000, and AAA is judged as CDMA1X-AN and inserts, and then AAA is issued to PDSN with the user specification under its this kind access way that in database, indexes; When NAS-PORT-TYPE was 24, access style was Wireless-1X-EV, and AAA is judged as HRPD-AN and inserts, and then AAA is issued to PDSN with the user specification under its this kind access way that in database, indexes.And when NAS-PORT-TYPE is 5; Access style is virtual; AAA continues to judge according to another attribute 3GPP2VSA of expansion the type of Interworking-type again; If be Interworking-type1, then AAA is judged as the WLAN-AN access, and the user specification under its this kind access way that in database, indexes is issued to PDIF; If be Interworking-type2, then AAA is judged as the WIMAX-AN access, and the user specification under its this kind access way that in database, indexes is issued to PDIF.
Wherein, PDIF can obtain the access style at terminal through static configuration, also can obtain through distinguishing the different protocol implementation, and then in being handed down to the authentication request message of AAA, identify this access style.Mode for static configuration; When inserting at the terminal; Different WLAN or WIMAX give the IP address of terminal distribution different segment; Corresponding relation in PDIF between the configuration of IP network segment and the access device, in the process of terminal and PDIF built tunnel, PDIF judges access device type and sign according to the IP address at terminal.For through distinguishing the different protocol implementation, be meant, if the terminal connects through different protocol with PDIF under the various access situation, then according to protocol type differentiation access way.Such as, now the WLAN access way is to set up the IKE tunnel between definition terminal and the PDIF, and WIMAX when inserting the definition terminal be other the mode of foundation that is connected with PDIF, all also do not relate in the standard here.
The above is merely a preferred embodiment of 3GPP2 of the present invention and WLAN intercommunication, and the mode of concrete access style also can be accomplished through in NAS-PORT-TYPE, increasing different values under the expression interconnected model.Increasing " 5=virtual " following concrete access way among the NAS-PROT-TYPE that defines in current RADUIS and the DIAMETER agreement is:
Original definition:
5 virtual；
19?Wireless-IEEE?802.11；
22?Wireless-CDMA2000；
23?Wireless-UMTS；
24?Wireless-1X-EV。
The value that increases is:
40?virtual?with?wireless?802.11；
41?virtual?with?wireless?802.16；
42?virtual?with?wireless?CDMA2000；
43?virtual?with?wireless?UMTS。
The value of above-mentioned increase promptly representes that with two digits concrete access style also is merely embodiments of the invention, only limits to this but not be used to limit its expression, and all the other possible values are not done specific descriptions at this.
At this moment AAA can go the corresponding user specification of index (user profile) to be handed down to NAS according to ID in the authentication message and NAS-PORT-TYPE.
Specify a kind of method of in the 3GPP2 network system, obtaining user specification of the present invention below in conjunction with accompanying drawing 4, comprise the following steps:
Network access server NSP obtains the access style of terminal MS, initiates authentication request to AAA, in authentication request message, increases the attribute of the access style that carries marking terminal;
The user specification that the AAA configuration is relevant with the terminal access style, the access style according to carrying in ID and the said authentication request message obtains corresponding user specification, and is issued to network access server.
Above embodiment is the scene of 3GPP2 and WLAN intercommunication, yet as previously mentioned, the present invention is not limited thereto, and this method can be used in the authentication access procedure in the other system.For example; Also there is same problem when 3GPP and WLAN intercommunication; Also can solve through said method; So method of the present invention is not limited in the 3GPP2 network, the scene of the network interworking of any CDMA network (for example 3GPP2,3GPP etc.) and other accesses (for example WLAN, WIMAX access etc.) can be used method of the present invention.
In sum; The present invention is through increasing an attribute in Radius Accept-request or Diameter Accept-request; Concrete access style when for example VSA (Vendor specific attribute) attribute identifies NAS-TYPE-PORT for " virtual "; Or the increase expansion identifies this access style in existing NAS-TYPE-PORT, has solved in the prior art and has not known the problem that can't dispose the relative users specification that access style causes because of AAA.
Can confirm user mode access and Operational Visit mode through ID, NAS-PORT-TYPE and newly-increased attribute among the AAA.And by these value corresponding user specifications of index index in database (user profile); Can obtain user specifications different under the different access waies; Realize QoS, authentication mode and wildcard, charging policy different under different the access and type of service can be provided, thereby can be implemented in the flexibility of configure user specification among the AAA.
And when initiating the authentication registration, PDIF both can also can obtain through distinguishing the different protocol implementation through the access style that static configuration is obtained the terminal, thereby this access style is identified.
In addition, as stated, method of the present invention can be used in the authentication access procedure in the other system.
The above is merely preferred embodiment of the present invention, and is not in order to qualification the present invention, and any variation and modification of doing according to claim of the present invention all should be contained in protection scope of the present invention.
