[0028] in addition, the application has described the various aspects that are used for terminal.Terminal can also be called system, subscriber equipment, subscriber unit, subscriber station, mobile radio station, travelling carriage, station, a distant place, remote terminal, accesses terminal, user terminal, user agent or subscriber's installation.Subscriber equipment can be that cell phone, cordless telephone, Session Initiation Protocol phone, wireless local loop (WLL) are stood, the module in the personal digital assistant (PDA), the handheld device with wireless connections ability, terminal, can be connected to or be integrated in card in the main process equipment (as, pcmcia card) or other is connected to the treatment facility of radio modem.

[0029] in addition, various aspects of the present invention can be embodied as method, device or use the goods of standard program and/or engineering, with generation software, firmware, hardware or its combination in any, thereby control computer or computation module are realized various aspects of the present invention.The term that uses among the application " goods " is contained can be from the computer program of any computer-readable device, carrier or medium access.For example, computer-readable medium can include, but are not limited to: magnetic memory device (for example, hard disk, floppy disk, tape etc.), CD (for example, CD, DVD etc.), smart card and flush memory device (for example, card, rod, key actuated device etc.).Should be understood that in addition, can use carrier wave to carry computer-readable electronic, as transmitting and receiving voice mail or those data of use in visited network (as cellular network).Certainly, those of ordinary skill in the art will recognize, on the protection range or spiritual basis that do not break away from the application's description, can make various modifications to this configuration.

[0030] referring now to Fig. 1, the profile modification that system 100 has described to be used to roam is so that in communication in wireless networks.Wireless terminal 102 (be also referred to as and be main frame) and access node 104 communicate, and access node 104 also communicates with visited network or territory 106, and wherein visited network runs into come from home network 110 roamings of serving wireless or accesses terminal.Should be noted in the discussion above that access node 104 can also be considered as the part in visited network or territory 106.Access node 104 also is referred to as base station or couple in router, access node 104 uses the various nodes, unit and/or the system that are included in the visited network 106 to be used for such as authentication service request, authorization service, to set up session or the like, and these will be described in more detail below.At first, visited network 106 receives the request of network insertion from wireless terminal 102.Carrying out after some shake hands with the available service of determining wireless terminal 102 with home network 110, home network generates to insert agrees 114, then responds this request, describes the profile 120 of serving from the home network emission.

[0031] after receiving profile 120, visited network 106 is at least in part according to the profile 120 that is received, and can be optionally 102 provides service to one or more accessing terminal.The profile service specified can with service quality (QoS) parameter of respective wireless terminal and relevant according to mailing to the communication session that visited network 106 requests set up, also will be described this in more detail hereinafter.In one aspect, visited network 106 is handled, revises, is deleted or add and serve for profile 120.This makes visited network 106 that a subclass of service can optionally be provided from profile 120 and/or other service except that the profile service specified is provided.By allowing to revise profile, visited network can consider dynamically to change its service provision according to current resource situation or other.

[0032] in one aspect, when home operator network 110 (for example, obtaining to insert via visited network) was left in user roaming, system 100 needed the relevant service of control subscriber equipment 102 and supports with user and/or service quality (QoS).In this roaming scence, be desirable to, service and QoS that the carrier network 106 of being interviewed can optionally be supported in 110 home-operator regulation support, and if necessary, the flexibility that provides service other and/or that substitute and QoS to support can be provided in the operator that is interviewed.

[0033] according to another aspect, user profiles 120 can be included in and insert in the acceptance message 114, wherein inserts acceptance message 114 and be from the authorization services device (AAS) of for example home network 110 to send to the AAS of visited network.Should be understood that, can also between other networking component, exchange profile 120.Subsequently, generate and insert acceptance message 114, and send user profiles 120 from the AAS that for example is interviewed to access node 104, wherein subscriber equipment 102 inserts by access node 104 requests.The configuration of the one or more qos parameters of user profiles 120 regulation and/or comprise and be used for the pre-authorization information of QoS configuration change subsequently, wherein pre-authorization information is to need providing differentiated services between the user and/or between the different application service of the mandate used of given user.

[0034] the one or more assemblies in the visited network 106 (for example, be interviewed AAS and/or access node) can be revised the user profiles 120 that ownership AAS or other networking component provide.Like this, user profiles 120 (for example, add, revise or the deletion service) can be revised by visited network operator, thus the service-conformance that itself and the carrier network 106 of being interviewed are provided.Because allow profile 120 is made amendment, control service and QoS when system 100 makes roaming can have flexibility.Thereby allow visited network operator to change (for example, add, revise, delete) user's service.Owing to use XML (or other structure) regulation service to have flexibility in user profiles 120, this method that changes profile at visited network 106 also makes the service definition that is provided constantly develop.

[0035] for example, terminal 102 can be as lower module, maybe can be used for any other suitable terminal of access network such as SD card, network interface card, wireless network card, computer (comprising on knee, desktop, personal digital assistant PDA), mobile phone, smart phone.Terminal 102 is via access node 104 access networks.For example, terminal 102 can be couple to access node 104 communicatedly via wired connection (for example, ethernet line, USB connection etc.).In another example, the connection between terminal 102 and the access node 104 can be wireless in essence, and wherein access node 104 can be the base station, and terminal 102 can be a wireless terminal.For example, terminal 102 and access node 104 can communicate via any suitable wireless protocols, and these agreements include but not limited to: time division multiple access (TDMA), code division multiple access (CDMA), frequency division multiple access (FDMA), OFDM (OFDM), flash OFDM, OFDM (OFDMA) or any other appropriate protocol.

[0036] similar with terminal 102, access node 104 can be the access node relevant with cable network or wireless network.Therefore, for example, access node 104 can be router, switch etc.Access node 104 can comprise the one or more interfaces that communicate with other network node, as communication module.In addition, access node 104 can also be the base station (or WAP (wireless access point)) in the cellular-type network, wherein uses base station (or WAP (wireless access point)) to provide wireless coverage area to a plurality of users.Can arrange that these base stations (or WAP (wireless access point)) are to provide continuous overlay area to one or more cell phones and/or other wireless terminal.

[0037] as mentioned above, system 100 can also comprise and be positioned at 106 and 110 authorization services device (AAS) that it helps to make terminal 102 can send/receive data on network by using access node 104.Though be depicted as entity separately in the drawings, should be understood that AAS 106 also can be included in the access node 104.About authenticated/authorized, terminal 102 can provide the data that show this terminal 102 and/or related with it user identity via access node 104 to AAS 106.Access node 104 can not add this recognition data revises ground to AAS 106 forwardings, or access node 104 can be revised these data according to any suitable data formats/protocols.When receiving this identification mark, AAS106 can authentication terminal/user identity, and judges whether one or more services of authorization terminal 102 (and/or user).

[0038] processing procedure of authenticated/authorized can (certain in certain embodiments) comprise, the one or more signals of exchange between terminal 102, access node 104 and/or AAS 106.If to terminal 102 and/or related with it some services of subscriber authorisation, then AAS 106 can transmit the profile of the modification of distributing to terminal 102 (or associated user) to access node 104, wherein this profile comprises the description of the qos parameter relevant with one or more Business Streams that relate to terminal 102 at least, wherein can be a succession of relevant packet (for example, identifying) with stream data definition based on checking packets headers and/or grouping payload.Profile 120 can also comprise filtering rule, and it is convenient to packet and Business Stream associates and QoS treatment and some Business Stream and/or the packet of regulation associated.According to an example,, these packets can be referred to as a kind of Business Stream when packet has when showing that this packet relates to the header of speech data.Equally, show that the packet that packet relates to video data can be a kind of different Business Stream.

[0039] after receiving profile, the QoS treatment of describing in the profile that access node 104 can be monitored and implement to be received.For example, the parameter that described QoS treatment is used can relate to the accepted time delay relevant with Business Stream, so access node 104 can be dispatched at this Business Stream, to keep the time delay of describing accepted from the profile that AAS 106 provides.Other qos parameter in the profile that receives can relate to about the I of concrete traffic flow types to be accepted data rate, can accept data rate or the like about the maximum of concrete traffic flow types.Can define with numeral (for example, the minimum data rate about first traffic flow types is 128Kb/sec) and/or definition relatively (for example, about the time delay of first traffic flow types be about the time delay of second traffic flow types 1/2) these parameters.In addition, the definition of parameter can be temporarily according to some system or network state and tentative.In one example, concrete parameter can relatively define before arriving thresholding, thereafter then with numeral definition (for example, should be the twice of second Business Stream about the minimum data rate of first Business Stream, but should be above 1M bps).

[0040] in addition, the profile that provides to access node 104 from AAS 106 can be supported the object instance in it, thereby reduces duplicating of profile intrinsic parameter definition.For example, can use three kinds of parallel Business Streams to support this application through authorizing to use by the recreation that terminal 102 is used.Not at each Business Stream defined parameters all, but, can be single Business Stream generation definition, then, can utilize the example of this definition for related service stream.In addition, profile can comprise filtration (for example, classification) rule, and it can be used for: discern concrete Business Stream; The example of this Business Stream with the QoS treatment of determining to distribute to this Business Stream is associated.After receiving profile, access node 104 can be provided at the QoS treatment of regulation in profile and the pre-authorization data set 120 to terminal 102.Therefore, access node 104 can provide different QoS treatment with a plurality of users to different Business Streams, thus enhanced system performance and user experience.

[0041] existing referring to Fig. 2, it has described can use the example network connecting system 200 of revisable profile data when roaming.Before continue describing, should be noted in the discussion above that at assembly shown in the system 200 and agreement be exemplary in essence, the more or less assembly of the assembly that provides than system 200 can be used and/or other agreement that provides can be utilized.System 200 comprises the wireless terminal 210 that is connected with base station (BS) 216 via 220 flash air interface.BS 216 communicates by letter with mandate (AAL) server 224 with local authentication through network link.The part that AAL 224 can be used as mobile network's server (MNS) provides.AAL 224 communicates with other AA server, for example, and ownership AA server (AAH) 230 and nonlocal AA server (AAF) 234.Home network 240 can be served by AA server 230, and wherein AA server 230 comprises that the initial service of WT 210 sets up record.This locality or visited network 244 are networks that WT 210 obtains network connectivty by chance.

[0042], then for example comprises and all BS, MNS/AAL in home network and the communication between the AAH (with shown in Fig. 2 different) towards the connection of home network if WT 210 attempts directly (because geographical position) to be connected with home network 240.Should be noted in the discussion above that WT210 is local (as shown in Figure 2) for visited network 244 when roaming, and WT 210 is local for home network 240 when not roaming.The following exemplary protocols of using has also been described by system 200 when Control Network inserts.These agreements can comprise connection control protocol (CCP), security association agreement (SAP), long-distance identity-certifying dial-in customer service (RADIUS) agreement and/or Extensible Authentication Protocol (EAP).Be understandable that, can also use other agreement Control Network to insert.

[0043] existing together referring to Fig. 3 and Fig. 4, it has described the authentication protocol of two grades.In one example, can use one or two different Extensible Authentication Protocol (EAP) to adopt two stages of the authentication of network insertion.Phase I shown in Fig. 3 relates to the authentication between wireless terminal (WT) 310 and home network AA server (AAH) 320 by base station 330 and local network AA server (AAL) 340.As shown in Figure 4, second stage realizes the authentication between WT 310 and the local network AA server 340.No matter WT 310 is positioned at its home operator network or roams in another carrier network, and the verification process in these two stages all will take place usually.Expectation WT 310 carries out local service by AAL340, and wherein AAL 340 is the AAH 320 that are independent of WT 310.The authentication in these two stages can realize expanding roaming, and realizes the critical material of local network and the suitable processing of service, and wherein local network is home network or visited network.Two stages of EAP should be separate.In other words, as long as can realize the mutual authentication of WT 310 and AA server 320,340, just can use different mechanism in each stage.

[0044] in first authentication phase that Fig. 3 describes, AAL 340 serves as radius proxy.Should be understood that, can also use other authentication protocol.Second stage realizes the authentication between WT 310 and the local network (AAL server) 340, does not relate to AAH as shown in Figure 4 here.The authentication second stage is added local network and is allowed WT 310 foundation this locality to trust.Local network can be the part of nonlocal carrier network (that is, not being home-operator), or the part of home-operator management domain.Use local trust to set up and be based on following reason, it comprises: make AAF/AAH not be subjected to the influence (no matter WT is roaming or not roaming) of local mobile, for other agreement AAL 340 is used as believable third party, and, user identity privacy highly is provided.

[0045] the used authentication phase of local network has been considered the user anonymity support.AAL 340 distributes temporary identifier to WT310, and it can not be connected to the persistent identifier of WT by " monitoring " air interface.Some reasons are that suitably mechanism makes and transmits interim WT identifier safely to WT 310, thereby guarantees confidentiality.Subsequently, WT 310 can use this temporary identifier to insert at the future network of this local network obtaining, if or WT be positioned at home network then be used for other host configuration purpose as required.Except that breaking the wall of mistrust, can also exchange profile, with further regulation service.

[0046] now turn to Fig. 5, it has described the exemplary profile 500 according to one or more aspects of the application's description.Profile 500 is logic groups of the parameter of the authorization service aspect of stipulating that user's (concrete portable terminal) uses.But, should be understood that, can change the territory/unit in the profile 500, make according to these claims, can change and how stipulate the unit, can change logic arrangement, can change element number and can change the unit title.Profile 500 can be relevant with flash service unit 502, and wherein service unit 502 is logic groups of some parameters, these parameters with set up via interface (for example air interface comprises the flash air interface) with keep connective relevant.Flash service unit 502 can be associated with position constraint unit 504, and wherein position constraint unit 504 is set of the parameter of assigned position (or tie point), can agree user's access service by these positions.In the time of in position constraint unit 504 is included in profile 500, can limit access according to the regulation of included unit in the position constraint unit 504.If omit position constraint unit 504, this expression inserts the restriction that is not subjected to the assigned position tabulation, but is subjected to the constraint of alternate manner, for example roaming agreement.

[0047] profile 500 can also comprise network element 506, and it can be and the set of concrete network-related parameters, can agree user's (terminal) access service by this concrete network.Access can be subject to the network of one group of indication, if necessary, can disagree with the access by other network.Network element 506 can be relevant with network identifier unit 508, and wherein network identifier unit 508 can be the GUID of network, wherein can agree user's access service by this network.Network element 506 can also be relevant with unit, region 510, unit, region 510 can be defined as the set of the parameter relevant with specific region in the network, wherein can agree user's access service by this network.Access in the network can be subjected to the restriction of the region of one group of indication in the unit, region 510.If there is not unit, region 510, mean that then the access of the network of sign is not subjected to the restriction of the region of one group of regulation in the network identifier unit 508.

[0048] unit, region 510 can relate to local identifier unit 512, and it can be the local unique identifier of region in the network, wherein can agree user's access service by this network.Unit, region 510 can also relate to base station unit 514, and it can be defined as the set of the parameter relevant with certain base station or access node (in the region of network), wherein can agree user's access service by these certain base station or access node.Access in the region can be subject to the base station of one group of indication in the base station unit 514.If lack base station unit 514, mean that then the access in the region of identifying is not subjected to the restriction of one group of certain base station.

[0049] base station unit 514 can be relevant with base station identifier 516, and base station identifier 516 can be the local unique identifier of base station in the region of network, wherein can agree user's access service by this network.Base station unit 514 can also relate to link unit 518, and it can be the set of the parameter relevant with particular link (corresponding with the base station that identifies in the region of network), can agree user's access service by this particular link.For example, can be subject to one group of link of regulation in the link unit 518,, then mean, not be subjected to the restriction of certain group link via the access of corresponding base station if in profile, lack link unit 518 via the access of base station.

[0050] link unit 518 can be relevant with logic link control identifier element 520, logic link control identifier element 520 can be the local unique identifier of the corresponding link in base station in the region with network, wherein can agree user's access service by this network.Link unit 518 can also be relevant with linkage unit 522, and linkage unit 522 is and the set of the parameter of specific join dependency, wherein can agrees user's access service by this specific connection.For example, can be subject to the connection of one group of indication via the access of link.If lack linkage unit, then mean, be not subjected to the restriction of the connection of one group of regulation via the access of respective link.Therefore, if no longer retrain access via particular link, what can expect so is not comprise linkage unit 522 in profile 500.Linkage unit 522 can be relevant with connection identifier (CID unit 524, and connection identifier (CID unit 524 is the links and the corresponding local unique identifier that is connected in base station in the region with network, wherein can agree user's access service by this network.

[0051] profile 500 can also comprise position renewal unit 526 at interval, its can be between example continuous time duration (for example, use second), wherein when wireless terminal for example is in " dormancy " pattern, this terminal should be at this moment between the example executing location upgrade.(for example, with millisecond) can be indicated duration between example continuous time in supervision interval unit 528, wherein be in the wireless terminal of " dormancy " pattern will be at this moment between example carry out page monitoring.Profile 500 can also comprise services set unit 530 (being discussed in more detail below), and it can comprise one group of type service and user service logic data configuration (relate to and enable and control service).This unit 530 can comprise qos parameter, and it relates to and some relevant Business Stream of particular terminal (for example, wireless terminal).Unit 530 also comprises pre-authorization template or the data that are used for carrying out from access node the dynamic quality of service configuration.Can use XML to transmit and comprise the profile information of (comprising qos parameter), and can define the structure and the further feature of this information with relevant XML pattern (schema), for example, data type, form and/or value constraint.

[0052] referring now to Fig. 6, it illustrates and has described example of service collection unit 600 (for example, the services set unit 530 of Fig. 5).But, should be understood that this unit only is as an example, and according to the present invention, unit here and/or the logical communication link between the unit can be deleted, change, keep or the like.QoS definition and be controlled to small part ground based on two kinds of data configurations in the services set unit 600: type service unit 602 and customer service unit 604.Though illustrate, should be understood that this unit can relate to subscriber equipment, for example wireless terminal as " user " service unit.Therefore, as the result of identification terminal mark and/or identification user mark, customer service unit can be included in the profile.According to the service that will provide, profile can comprise the repeatedly appearance of any or the two of these data configurations.Type service unit 602 (data configuration) can provide a kind of common mechanism, and it is used to stipulate the QoS treatment of the Business Stream relevant with the special services examples of types.For example, to be divided into one or more Business Streams to the/grouping that provides from main process equipment, wherein given Business Stream can only comprise and a corresponding particular flow of packets of application-specific that perhaps given Business Stream can comprise the sum total with the corresponding stream of packets of a plurality of application.

[0067] referring to Fig. 9, it has described to use the above-described example roaming system 900 of revising profile.A kind of roaming scence has been described by system 900, and in this scene, subscriber's main station (SH) 910 obtains to insert via visited network 920 (that is the network that, is different from its home network 930).In this example, between home network and visited network operator, generally roaming agreement 940 can be arranged.Generally speaking, home network operator gets involved the authentication of SH 910 and the agreement mandate of access.Suppose the access of home-operator agreement SH 910, then visited network operator can make SH obtain service via its local access network.But any or two Virtual network operators can provide basic network service and more high-grade service.Dotted line in the system 900 has conceptually been represented basic network service and/or more high-grade service.When roaming, SH 910 can from be interviewed/receive service local domain 920, home network or territory 930 or the two.Therefore, user's service mechanism (for example, the user profiles of indication authorization of service) should provide sufficient information, allows to carry out service support by any territory.Scene system 900 can also be represented an example of MVNO (MVNO), and for example, home network 930 is situations of MVNO.In the case, MVNO can comprise needed network element of support " roaming " and software, but does not comprise access network.Therefore, though SH 910 and MVNO are relevant in management, it is access belonging network 930 but through the form appearance of visited network 920 to roam directly.

[0068] referring to Figure 10, virtual going home (virtual homing) scene has been described by system 1000.The virtual scene of going home that system 1000 is described expresses support for another example (for example, virtual ownership 1030 is situations of MVNO) of MVNO, and it has also represented the example (for example, virtual ownership 1030 are dedicated networks situation) of virtual support private network (VPN).The main distinction of itself and above-described system 900 is: in system 1000, SH 1010 is relevant with local network 1020 (obtaining to insert by this network SH 1010) in management, and promptly local network 1020 is home network.Therefore, this locality/home network operator generally gets involved in the authentication of SH 1010 and the agreement mandate of access.Yet SH1010 also is associated with the virtual ownership of describing 1030, and wherein virtual ownership 1030 can be MVNO or VPN is provided special use (for example, the enterprise) entity of service.With the same in the system 900, the dotted line of description is represented basic network service (for example, addressing/route), and ownership/local domain 1020, virtual home domain 1030 or potential more high-grade service that the two can provide.

[0069] referring to Figure 11, virtual going home and roaming scence described by system 1100.System 1100 has represented the combination of those parts of explanation in above-described system 900 and 1000.In this example, when obtaining to insert via visited network 140, SH1110 is associated with home network 1120 and virtual ownership 1130.In like manner, generally speaking, home network operator gets involved in the authentication of SH 1110 and the agreement mandate of access.But, in this system 1100, three dotted arrows have been described, its expression basic network service is (for example, and be interviewed addressing/route) ,/potential more high-grade service that the combination in local domain 1140, home domain 1120, virtual home domain 1130 or three territories can provide.

[0070] referring to Figure 12, it has described the method 1200 relevant with roaming with profile modification.Though in order to make explanation simpler, and this method is illustrated and is described as a series of action, but should be appreciated that and understand be, this method is not subjected to the restriction of sequence of movement, because, according to one or more embodiment, some actions can by different order take place and/or with shown in the application and other action of describing take place simultaneously.For example, it should be understood by one skilled in the art that and understand that a kind of method also can be expressed as a series of state and incidents of being mutually related, as in state diagram.In addition, carrying out method of the present invention is not the action that needs to use all explanations.

[0071] particularly referring to Figure 12, it has described method 1200.Method 1200 starts from 1202,1204, generates service request from visited network.For example, at first can be by home network mandate portable terminal, but because its present position, portable terminal request now inserts from subsequent network (it is referred to as visited network or territory sometimes).1206, from home network request profile.Visited network can generate this request, to respond 1204 service request.For example, profile can be specified the service such as QoS parameter simultaneously, wherein supports the service of this class during angelica network authorization terminal.1208, after home network generates the access agreement, launch this profile to visited network from home network.As previously mentioned, the virtual aspect that provides such as MVNO (MVNO) or other VPN (virtual private network) assembly can be provided home network.

[0072] inserting agreement after exchange handshake signals or the code between home network and visited network can take place.1210, can not change the profile that is received, perhaps if necessary, then can revise the profile that is received.Profile modification can comprise adding in profile serves, the parameter relevant with respective service in deletion service and/or the adjustment profile from profile.Therefore, because the profile that is received, visited network can provide the service similar to home network, if one or more services of deletion from the profile that is received, one group of service of minimizing then can be provided, if visited network adds service in the profile that is received, then can provide a superset of service.1212, use this profile that the service of one group of expectation is provided to the wireless access terminal.

[0073] present one referring to Figure 13 and Figure 14, it provides about the profile modification of terminal, carrier network, access node and Business Stream thereof and the system of roaming.With these system representations is a series of functional modules that are mutually related, and these functional modules can be represented the function by processor, software, hardware, firmware or its any appropriate combination realization.

[0074] specifically referring to Figure 13, system 1300 helps the communication from visited network.System 1300 comprises the logic module 1302 that is used to receive from the user profiles of home network generation.Use logic module 1304 to revise user profiles, use logic module 1306 to come partly to provide service according to the user profiles of revising.Modification to user profiles can comprise interpolation service or deletion service from profile, the perhaps interior parameter of modification/editor's profile in profile.

[0075] referring to Figure 14, system 1400 helps in roaming environments the communication from home network.System 1400 comprises the logic module 1402 that is used for generating from home network user profiles.System 1400 comprises and is used to make commentary and annotation user profiles so that the logic module 1404 that can make amendment to profile also is useful on the logic module 1406 of agreeing access belonging network.

[0076] referring to Figure 15, it has described to use the example network 1500 of the profile data of roaming between network.The operator internet 1510 with two couple in routers (AR) 1514 and 1518 has been described by this system 1500, and other network element, and wherein subscriber's main station (SH) 1520 can obtain to insert by these two AR.Make with dashed lines that logic interfacing between the various unit is described.Because being provided with, the position of AR 1514-1518 can control via the infrastructure of operator to the access of available service with directly control the QoS of these services on the access link, so be network element at the service time AR1514-1518 that controls environment.Yet many similarly other network element also may be at figure in the solution fully, for example, and the operation of control AR 1514-1518.Following description focuses on each logic interfacing shown in the system 1500, and relevant network element.

[0077] the credible indication of user identity (or user identity relevant with SH 1520) is very basic for the notion of control service on the different user basis.Generally speaking, before agreeing user access network and more high-rise service, for example use Extensible Authentication Protocol (EAP) that the identity of user's indication is authenticated.This initial authentication and authorization process is usually directed to use such as remote authentication dial-in customer service (RADIUS) agreement and communicates by letter between (ask to insert by these unit, these unit for example be AR 1514-1518) and the independent authorization services device (AAS) 1530 in the unit.Suppose that AAS 1530 has authenticated user identity and authorized user 1520 obtains to insert, return the indication of agreeing access from AAS 1530 to the unit so, wherein ask to insert by this unit.

[0078] after initial access is agreed, AR 1514-1518 can begin to send charge informations to accounting server (ACS) 1540, for example, and the packet/byte number.The charging of the Traditional IP service of doing one's best only comprises the simple total packet/byte number that transmission/reception is professional usually.Yet, support one group more to enrich user service and also can use and can realize based on the book keeping operation of serving and the billing mechanism of charge.Therefore, the details about employed service and/or the QoS grade that provided should be provided for the charge information of AR1514-1518 collection/report for example.

[0079] structure that provides according to the application, SH 1520 can connect and o'clock change to another AR from an AR, and this process is commonly referred to switching.Mobile IP (MIP) supports ambulant a kind of approach in the IP the Internet, and it uses tunnel management route/forwarding, thereby allows mobile host to continue to use identical address when changing its tie point.When switching, can use context transfer (CT) mechanism that service disruption is minimized.When switching, by between AR, transmitting information about authorization of service and QoS configuration, can faster and foundation service of equal value efficiently via new AR.Should be noted in the discussion above that newly AR should carry out access control when receiving when moving on to the relevant QoS configuration information of new AR with SH 1520, before indicated service is provided, whether have enough resources to use with judgement.

[0080] resource control interface 1550 uses signaling protocol, and SH 1550 can be by signaling protocol request QoS configuration change after initial access is agreed.As mentioned above, this can comprise one group of available QoS data and parameter, and it can be asked by SH 1520 when dynamic situation needs.As a rule, people can not suppose to support end-to-end QoS between another main frame that SH 1520 and SH are communicating by letter.But system 1500 provides QoS structure, wherein for large-scale service, only needs resource reservation at AR 1514-1518, rather than all needs resource reservation along whole data path.In other node of data path, needing under the situation of resource reservation, can use alternative or other resource control signaling.According to this model, SH 1520 should ask to be used to the resource of the business that sends and receive.Though the resource control interface 1550 between SH 1520 and the AR has been described by system 1500, from unit, operator's main frame (OH) or the application server of the operator the Internet 1510 of representing SH through being equal to or similarly the resource control interface also can support the QoS configuration.

[0081] a kind of mechanism of policy control interface 1554 expressions, by this mechanism, can its mandate of verification for the QoS configuration change of for example asking via resource control interface 1550.Should be noted that, as shown in the figure, described policy control interface 1554 between AR 1514 and the non-dedicated network element function as PDP 1560, for example wherein the PDP function can be arranged in special-purpose strategic server, application server or some other network element.The possible cause of this difference is that the suitable placement of PDP function 1560 depends on concrete service.As a rule, different services can in addition related different PDP, therefore according to some embodiments of the present invention, service definition comprises the indication of relevant PDP.
