Description
Technical field
The present invention relates to the communications field, relate in particular to a kind of micro-wave access to global intercommunication (WiMAX, Worldwide Interoperability for Microwave Access) method and system of Access Service Network Gateway (AGW) notice authentication, mandate and billing function entity (AAA, Authentication Authorization andAccounting) release user conversation in the system.
Background technology
WiMAX is based on the wireless access wide band technology of IEEE 802.16 standards, and it can effectively utilize the limited wireless frequency spectrum resource bigger bandwidth of air-interface is provided.Comprise in the network reference model of WiMAX system: Network Access Provider (NAP, Network Access Provider), home network services provider (H-NSP, Home-NSP), the visited network service provider (V-NSP, Visit-NSP).
Wherein, NAP is the business units that WiMAX wireless access framework is provided for one or more WiMAX Internet Service Providers (NSP, Network ServiceProvider).Comprise one or more access service network (ASN, Access Service Network) among the NAP, WiMAX NWG standard code, ASN has two kinds of frameworks: the ASN of MODEL C is made up of base station (BS, Base Station) and these two stand-alone network elements of AGW; The ASN of Model B only comprises comprehensive base station (IBS), the BS+AGW of its functional equivalent in MODEL C.Wherein, the NWG full name is Network Work Group, refers to WiMAX network work group, is the working group that is devoted to study the WiMAX system definition network architecture and reference model in the WiMAX tissue.
H-NSP is the local network service provider, and H-NSP is an operator or commercial organization, and it has the user-dependent Service Level Agreement with WiMAX; The session of authentication and authorized user comprises in the net and roaming scence; The charging of customer service comprises and chargeing and bill.In order to support services of roaming, a H-NSP can have roaming relationships with other NSP.Ownership authentication, mandate and the accounting server (HAAA, Home Authentication Authorization andAccounting) and home agent (HA, the Home Agent) network element that mainly comprise the storing user subscription business in the H-NSP network.
V-NSP defines from roamer's angle, and the roamer uses the wireless coverage visit WiMAX service of V-NSP.V-NSP can have roaming agreement with user's H-NSP, and V-NSP is provided to the professional route of HAAA of H-NSP.Based on the roaming agreement between user WiMAX service request and H-NSP and the V-NSP, V-NSP can provide some or all of WiMAX business to the roamer, perhaps provides the professional route of data/control to H-NSP.Mainly comprising in the V-NSP network provides visit authentication, mandate and accounting server (VAAA, Visit Authentication Authorization and Accounting) and the HA network element of acting on behalf of forwarding capability.
Say from another point of view, the WiMAX network is by subscriber station (SS, Subscriber Station)/travelling carriage (MS, Mobile Station), ASN be connected business network (CSN, Connect Service Network) three logic entities are formed, and wherein, each logic entity has all been represented one group of functional entity, and each functional entity can be realized in single physical equipment, also can be distributed in a plurality of physical equipments and realize.
Wherein, ASN is mainly WiMAX user corresponding wireless access and control is provided, and ASN is by BS and AGW) form.According to the function difference that realizes, AGW can be decomposed into a plurality of functional entitys again, these functional entitys comprise: datapath function (DP, Data Path), paging controller (PC, pagingController), dynamic host configuring protocol agent, dynamic host configuration protocol relay, external agent (FA), authentication functions entity (Authenticator), service flow authorization (SFA, Service Flow Authorization) functional entity.
Wherein, topmost R3 reference point and the R5 reference point that comprises the authentication functions entity among the ASN, AAA and bearing protocol interacting message related to the present invention, the functional entity/network element among all the other ASN or the CSN is auxiliary.Wherein, the authentication functions entity is responsible for mutual by dialling in the service for checking credentials (Radius, RemoteAuthentication Dial In User Service) agreement and AAA.CSN has comprised AAA and HA for MS provides IP Connection Service.
Fig. 1 for existing user access network when chargeing based on IP to the schematic diagram that exits network, roughly enumerated a WiMAX user from access network, use Internet resources, to a process that exits network, beginning, the termination of charging and the release of associated user's session and chargeable session resource that the user charges in this process, have been related to.
Here need probably to introduce following two sessions: user conversation and chargeable session.Wherein, to be the user once initially be linked in the middle of user's exiting network process user conversation, the cover casual user information that each network element node or functional entity are safeguarded for the normal mobile management of maintenance customer and session management among the WiMAX, these information produce when initial the access, when exitting network, the user withers away, produce when in AAA, being presented as user's initial access authentication, when chargeing termination, wither away.Wherein, chargeable session is to need the session kept between the termination in the beginning and chargeing of chargeing, and is presented as at AAA and receives and open chargeable session, termination chargeable session when receiving the charging ending message when chargeing beginning message.
Below in conjunction with Fig. 1, the beginning of these sessions down and the process of extinction are described roughly.Present user's synchronization can distribute an IP address, promptly opens after being assigned to this IP address and charges, and discharges the back in the IP address and stops chargeing, and exit network.As shown in Figure 1, mainly may further comprise the steps at the process of chargeing based on IP:
Step 101, terminal prepare to enter network, initiate initial access authentication.
Step 102, authentication success, AAA accepts message informing AGW authentication success by the access of Radius type, and relevant authorization parameter is also accepted message by this access is issued to AGW.
Here, the charge mode that has just comprised current access session in these authorization parameters: IP-based charging, also be based on the charging or the like of stream.AAA can create the user conversation of this access for this user simultaneously, keep the relevant information of this session, as AAA session identification (AAA-Session-ID) but, user's charging identifier (CUI), KI (MSK), MIP authentication extension key (MIP Key) etc., these parameters all are parameters relevant with this user conversation.
After step 103, authentication and registration are finished, be responsible for the user by AGW and set up terminal, be used for terminal and obtain IP address and message forwarding to the Data-carrying passage the AGW.
After step 104, AGW detected the user and get access to the IP address, AGW began request message for the charging that this user sends a Radius type, and AAA opens a chargeable session for this user.
Here, after AGW detects the user and gets access to the IP address, such as intercepting DHCP (DHCP, Dynamic Host Configuration Protocol) server mails to DHCP successful respond (ACK) message of MS, this inserts the charging that session is based on IP to learn aaa authorization from step 102, therefore AGW begins request message for the charging that this user sends a Radius type, and AAA opens a chargeable session for this user.
The charging that step 105, AGW receive the Radius type of AAA begins response message.
Step 106, user begin data service, and after business was finished, terminal initiated to move back the net flow process, prepared to withdraw from the WiMAX network.
Step 107, move back net network success after, AGW need stop request message to the charging that AAA send the Radius type, is used to report charge information, also stops request message itself by chargeing simultaneously, informs that AAA can discharge the resource that this user conversation is correlated with.
Here, discharge the relevant resource of this user conversation and comprise: the content that the AAA that lists in the step 102 need preserve is a part that needs the resource that discharges.
At based on flow based charging, a user can set up many streams in the process that once inserts, that is: a plurality of data channel of between terminal and AGW, setting up, wherein the stream of article one foundation is called initial service flow, can represent with ISF stream, remaining is a pre-provisioned service flow, can represent with PSF stream.Similar substantially at process and process of chargeing shown in Figure 1 based on IP based on flow based charging, but owing to be based on the charging of stream this moment, therefore after AGW detects terminal and obtains the success of IP address, each bar stream is all to being used to open the corresponding chargeable session of this stream in requisition for sending the beginning request message that charges, equally, AAA can set up a chargeable session for each bar stream, user conversation and chargeable session are 1 among the AAA like this: the relation of n, the charging termination messages of ISF stream must send at last, and AAA depends on the corresponding charging termination messages of ISF stream and discharges user conversation.
From top process as can be seen, the release of user conversation is based on the charging termination messages.Do not have the termination that clear and definite field shows user conversation in the present agreement, at the scheme that adopts existing release user conversation for instance, when chargeing based on IP, because a user has only charge a beginning and a charging ending message, therefore, can indication charging ending message clearly be exactly that user conversation discharges; In charging based on stream, because corresponding each stream is deposited the charging that all exists separately and is begun message and charging termination messages, therefore, when just requiring AAA to receive the charging termination messages of ISF stream, if the charging termination messages of ISF stream is last the transmission, then discharge user conversation.
Along with the development of agreement, following situation may appear in the termination of the user conversation that the termination of chargeable session might not be meaned: one, the user may not expect to exit network immediately after discharging IP, and a new IP address is obtained in expectation again; Two, terminal may be supported different cut-in convergent types, such as, support simultaneously based on internet protocol version four (IPv4, IP version4) converge and based on IPv 6 (IPv6, IP version4) converges, and all need an ISF stream for different converging, promptly ISF stream is also possible many, discharges the user with infeasible by identification ISF stream so; Three, the user may have a plurality of IP address simultaneously.Under these three kinds of situations, adopt the existing scheme that discharges user conversation, because in the field that existing charging termination messages carries, do not have the termination that clear and definite field shows user conversation, therefore, the field that existing charging termination messages carries at present can't clearly be indicated the release of user conversation, can not meet the demands, and must will have method for distinguishing to indicate AAA to discharge user conversation.
Certainly, aaa server is after the charging termination messages of all streams is all received in user conversation, also can judge this user conversation must stop, but in fact in some scenes, even the charging of all PSF streams stops, session also not necessarily can stop, and for example network may be set up new Business Stream when the user uses new IP address.Clearly carry the sign whether user conversation stops when so just needing AGW to send the charging termination messages to AAA.In sum, press for a kind of AGW at present and can clearly indicate the current scheme that whether needs to discharge user conversation of AAA.

Embodiment
Basic thought of the present invention is: AGW discharges the indication field relevant information by the user conversation in the release message, and whether notice AAA is current needs to discharge user conversation.
Be described in further detail below in conjunction with the enforcement of accompanying drawing technical scheme.
A kind of method that discharges user conversation, this method comprises: AGW discharges the indication field relevant information by the user conversation in the release message, and whether notice AAA is current needs to discharge user conversation.
Wherein, the information difference in the release message, the realization of this method is also different, first kind of realization: the user conversation in the release message discharges the indication field relevant information and is specially: in the release message, carry user conversation release indication field and indication and move back net.At this moment, after AAA receives this release message,, determine the current user conversation that needs to discharge according to the indication of user conversation release indication field relevant information.Second kind of realization: user conversation in the release message discharges the indication field relevant information and is specially: in the release message, do not carry user conversation and discharge indication field or carry user conversation and discharge indication field and do not indicate and move back net.At this moment, after AAA receives this release message,, determine the current user conversation that do not need to discharge according to the indication of user conversation release indication field relevant information.Below, above these two kinds of realizations are carried out specifically setting forth for example.
First kind of situation: move back under the net situation, the specific implementation flow process of this method may further comprise the steps:
Step 201, AGW are by stopping the current release user conversation that needs of charging request message notice AAA.
Here, stop in the charging request message, carry user conversation release indication field and indication and move back net.
Wherein, carrying user conversation discharges indication field and indication and move back the identification means of net and specifically comprise: user conversation discharges the ident value of indication field for true.
Step 202, AAA receive the termination charging request message; Discharge user conversation, all chargeable session that stop in the user conversation retreat net, and will stop charge response message and return AGW.
Second kind of situation: do not move back under the net situation, the specific implementation flow process of this method may further comprise the steps:
Initial service flow charging request message notice AAA is current not to need to discharge user conversation by stopping for step 301, AGW.
Here, stop in the initial service flow charging request message, do not carry user conversation and discharge indication field or carry user conversation and discharge indication field and do not indicate and move back net.
Wherein, carrying user conversation discharges indication field and do not indicate the identification means of moving back net specifically to comprise: user conversation discharges the ident value of indication field for false.
Step 302, AAA receive and stop the initial service flow charging request message; Do not discharge user conversation, do not move back net, and will stop the initial service flow charge response message and return AGW.
In sum, content of the present invention mainly comprises: when the user exits network, AGW carries user conversation and discharges indication field in the termination charging message that AAA sends, this user conversation must be discharged in order to show to aaa server, and all relevant chargeable session also must stop simultaneously.
Method embodiment one: the situation of moving back net.AGW sent to AAA and has the termination charging message that user conversation discharges indication field when the user moved back net.Handling process as shown in Figure 2 may further comprise the steps:
Step 401:MS sets up ISF stream, to be used to transmit the signaling that the IP address obtains.
Step 402:MS sets up PSF stream, to be used for user's bearing data service.
Step 403:MS sends DHCP such as dynamic host configuration protocol relay and discharges request to AGW.
Here, step 403 and following steps all are the processes that the user moves back net.
Step 404:AGW transmits DHCP to Dynamic Host Configuration Protocol server and discharges request, and DHCP removes current IP address binding; MS sends login request message to BS.
Here, login request message can be represented with DREG_REQ.
Step 405:BS returns registration reply message to MS; BS sends the data channel register requirement to AGW, discharges all Business Streams.
Here, Business Stream comprises ISF stream and removes that other PSF flows the ISF stream.
Step 406: the user exits network, and AGW sends to aaa server and stops charging request message, at first stops the charging of PSF stream; Aaa server returns the termination charge response message.
Step 407:AGW sends to aaa server and stops charging request message, stops the charging of ISF stream.
Here, because AGW finds that the user need move back net, therefore, in stopping charging request message, need comprise user conversation and discharge indication field, and net is moved back in indication.
Step 408:AAA server has been received after the termination charging request message that has user conversation release indication field, discharges user conversation, stops chargeable session all in this user conversation.
Step 409:AGW receives the termination charging request message, and AGW discharges the shared resource of this user, responds to BS return data channel registration.
Method embodiment two: the situation of not moving back net.The user does not plan to move back net after discharging an IP, but need redistribute an IP address.Flow process as shown in Figure 3 may further comprise the steps:
Step 501: the user sets up ISF stream, to be used to obtain the IP address.
Step 502: the user sets up PSF stream, to be used for bearer service data flow message.
Step 503: the user discharges the IP address of current use; AGW sends the data channel register requirement to BS, discharges relevant ISF stream and PSF stream.
Step 504: eat dishes without rice or wine to discharge related resource; AGW initiates to stop charging request message to aaa server, stops the charging of PSF stream.
Step 505:AAA returns the termination charge response message; AGW initiates to stop the initial service flow charging request message to aaa server, stops the charging of ISF stream.
Here, stop not carrying in the initial service flow charging request message that the user moves back the net indication or net is not moved back in indication, that is: in stopping the initial service flow charging request message, do not carry user conversation and discharge indication field or carry user conversation and discharge indication field and do not indicate and move back net.AAA receives and stops after the initial service flow charging request message, although all relevant Business Streams charge all stops, and does not still discharge user conversation.
Step 506:AAA server sends and stops the initial service flow charge response message to AGW; BS sends the data channel registration and responds AGW.
Step 507:MS initiates to obtain the process of IP address again.
It is to be noted: among the said method embodiment, user conversation discharges indication field and does not exist in present standard, that is: do not exist in existing termination charging request message.Based on the Radius agreement, the present invention has provided this field and has accepted design in the message in the access of Radius.As shown in Figure 4, comprise among Fig. 4: Radius type field, length field, identification of the manufacturer field, be nested in the field in the identification of the manufacturer field.Wherein, the Radius type field is represented the type Radius of current message, with numerical value 26 signs; Till length field begins to discharge indication field to user conversation from the Wimax type field; The identification of the manufacturer field can be WiMAX.When the identification of the manufacturer field was the WiMAX type, the field that is nested in the identification of the manufacturer field comprised: WiMAX type field, length are a byte; Length field, length are 1 byte; Burst field, length are a byte; User conversation discharges indication field, and length is a byte.
Particularly, the user conversation in the top example discharges indication field and is not only applicable to the Radius agreement, if adopt Diameter rather than Radius agreement between AGW and the aaa server, the design of this field should be suitable equally.Wherein, Diameter is an aaa protocol of new generation.
Radius manufacturer defined attribute (VSA, Vender SpecificAttribute) with regard to user conversation release indication field comprises this VSA in the Accounting Stop message of this Fig. 4, and this VSA possesses following function:
If comprise this VSA in the termination charge response message of a Radius type, and the user conversation value that discharges indication field be very (true), shows that then aaa server can discharge this user's session.
If but the value that does not comprise this VSA in the termination charge response message of two Radius types or comprise this VSA user conversation release indication field shows then that for false (false) aaa server can not discharge this user's session.
A kind of system that discharges user conversation, this system comprises: notification unit, be used for the user conversation of AGW by release message and discharge the indication field relevant information, whether notice AAA is current needs to discharge user conversation.
Because the release message difference, the user conversation that comprises in the message discharges that the indication field relevant information is different, and therefore, the specific implementation of notification unit is also different, thereby the specific implementation of system is also different, below sets forth respectively.
First kind of specific implementation of system: moving back under the net state, this system also comprises response unit; Wherein, notification unit is further used for AGW by stopping the current release user conversation that needs of charging request message notice AAA.Wherein, stop in the charging request message, carry user conversation release indication field and indication and move back net.Response unit is used for AAA and receives the termination charging request message; Discharge user conversation, all chargeable session that stop in the user conversation retreat net, and will stop charge response message and return AGW.
Second kind of specific implementation of system: do not moving back under the net state, this system also comprises response unit; Wherein, notification unit, initial service flow charging request message notice AAA is current not to need to discharge user conversation by stopping to be further used for AGW.Wherein, stop in the initial service flow charging request message, do not carry user conversation and discharge indication field or carry user conversation and discharge indication field and do not indicate and move back net.Response unit is used for AAA and receives termination initial service flow charging request message; Do not discharge user conversation, do not move back net, and will stop the initial service flow charge response message and return AGW.
The dynamic host configuration protocol relay that more than relates to can be represented with DHCP Relay; The authentication functions entity can be represented with Authenticator; Stopping charging request message can represent with Accouting Stop; User conversation discharges indication field and can represent with User-Session-Stop Flag.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.
