Abstract
This invention offers tiered application services for access to network services on a pay-per-use basis in public access networks. Using personal devices (108), the user can access different tiers of application services on demand (103, 104), without the need of any preexisting association, e.g., subscription, with the service provider of the wireless access system (111). Such on-demand access is obtained by providing a variety of personal identifiers, such as a credit card number or frequent flier identification. Moreover, the service offering allows a user through a personal device to modify, enhance or degrade the currently established tier of application services during the lifetime of the user's association with the access network. A network-level enforcement mechanism at access points within the access network ensures user access only to application services within the application service tier that they have paid for, and denies service accesses not within that tier.
Description
Right of priority
The application requires to be filed on March 8th, 2002, institute's distributing serial numbers is the right of priority of U. S. application 60/363,327, that have same title.
Technical field
The present invention relates to the field that computer network connects.Relate in particular to access to the Internet by the network infrastructure that can openly visit.
Background technology
The present invention relates to a kind of mechanism, can utilize themselves personal device by this mechanism user, visit based on the network service of wrapping (packet-based) as notebook and personal digital assistant (PAD), these network services are being provided as public arenas such as airport, market, hotels by the service provider.This class public visit service provider can provide multiple wired or wireless technology, by these technology people their personal device is connected to network and its related service.Along with the appearance of LAN (Local Area Network) with the new wireless technology standard (referring to WLAN and wireless PAN respectively) of a territory net (personal area network), we see that the quantity that the COS that quantity especially considered among the present invention is provided of public service is just increasing rapidly.For example, the public wireless visit can be passed through wireless lan technology, such as those technology based on IEEE 802.11 series standards, perhaps by wireless PAN technology, provides such as blue tooth wireless technology.
Typically, provide and require the user,,, concern thereby set up long-term " payings " with this provider as subscribing as ISP (ISP) registered in advance at first to data service provider based on the data, services of bag.This process is finished with offline mode usually, sets up and activate one subscriber of this provider relation before this user can visit this public service.This subscriber's relation comprises the definition of user profiles, the service range that this definition has specified this personal user to be authorized to visit.ISP generally provide a locality or even free (toll-free) telephone number, it allows from many geography remote position to visit this same ISP with a kind of extra increase expense (except that subscription fee).Yet, for go access data services by wireless public service for, this mechanism has important disadvantages: if the user attempts to visit the public access infrastructure by provider operation, they have set up the provider of subscription relationship with it and this provider is different from those, these users will be rejected visit so, unless they also subscribe to this new provider.The prerequisite of public access infrastructure has been defeated in such restriction, and it wishes to be always user's service as much as possible (and to its charge) ideally.
And, current public visit to the network service, use the single grade of service of scheme definition of wireless technology usually.For example, a typical service is only to the visit of WWW (or briefly, " Web ").Such service definition is not considered such situation, wherein the user can by themselves equipment on request (on demand) visit the service (premium service) that some needs charged extra.Do not have such mechanism, it allows user at any time dynamically to select one or more such charged extra services, and does not need and such service opening relationships in advance.Even service provides a plurality of grades (or service groups) are arranged really, the user must select their desired services grade in advance.And, during service that user capture is provided by this service provider in, the selected grade of service remains unchanged.In other words, current service by public access infrastructure provide do not offer the user different and dynamically (or on request) adjustment the grade of service.Such service provides also and need come mechanism for user's dynamic adjustments payment policies based on user-selected services set.In addition, for above-described providing is provided in real time, should.
Providing a kind of possible solution aspect the graduation service by special code is installed in client (being the user) equipment on request.It is essential that this special code will influence communication protocol stack and the use of new specific protocol is become.Each bag that is produced by these client devices all needs to use this additionally to be modified with special code.Certainly, the network components in these networks must move the complementary portion of this new specific protocol can read these amended bags.It will be favourable having the method that does not need the change in the protocol stack.This method should use existing TCP/IP standard to need client device to carry out New Deal so as to not make, so as not to needing client device must revise its each transmission, and so as not to the communication protocol stack that needs equipment in the network must revise them to understand newly-designed agreement.
Last point be it should be noted that and had other possibilities that are used to dispose the public wireless service.For example, system proposes to use the special software that will be embedded on the personal device, with by revise each by the packet of these device transmission with convenient visit public service.
It will be useful having a kind of like this system, and this system does not require being used to visit on the personal device of wireless network makes any change, and need not make any modification on the packet by these device transmission, to reach the various of it.Previously described system depends on the particular characteristics of operating platform (its server or Client version).This has set up communication for the equipment that participates in network enabled and has calculated homogeneous operation hypothesis.Be more preferably equipment with the change of can be applicable to not and the system on the communication protocol, its equipment that can be used the open communication standard of having established is applied in nonhomogeneity calculating and the communication environment, these open communication standards, as the TCP/IP suite of the Internet protocols, most individual's (IP enables) equipment that runs on the dissimilar operating system that struck the beam is supported.These personal devices should be structured on the software and hardware platform of the software and hardware platform that is independent of network support equipment, and wherein these personal devices and this network support equipment carry out mutual to carry out its configuration.About keeping accounts, aforementioned system does not allow dynamically to reassign accounting policy in the centre of just carrying out session.
Summary of the invention
Therefore an aspect of of the present present invention is to allow the supplier of public network service that the user of the application service of different brackets to these application services is provided.The user uses themselves personal device, so that by each application service tier of using and in an ongoing use, consulting and dynamically adjust their expectation, for these personal devices, do not make special modification for adapting to professor of the present invention.
Another aspect of the present invention is the execution mechanism that can be applicable to support in the structure base communication that described public service provides.This execution mechanism can be applicable to the assembly of this architecture inside, as router device, or at the assembly at architecture edge, as WAP (wireless access point).This execution mechanism guarantees to demonstrate,prove the personal user can only visit those application services in the application service tier that they have selected, and refusal does not belong to the visit of the application service in this grade to all.In certain embodiments, this execution mechanism has also been replenished the device of warning user when the user attempts to visit the particular application services that does not belong in current their the selected grade, and replenished such device, the words user who wishes can dynamically consult new desired application service tier again with themselves equipment once more by this device users, so that if can visit new application service.
Another aspect of the present invention is a kind of execution mechanism with purpose as hereinbefore, it can be applicable to outside the communications component (as router and WAP) of architecture, such as the equipment and the software that are operated in the higher protocol level of those protocol level of being used for structure base communication.Utilize such execution mechanism, filtering server can be used on the structure base communication only to arrive the Web service that belongs to the application service tier that they have selected will be for example to be restricted to from user's Web communication stream.
One side more of the present invention is to make the user can use themselves equipment to visit the dynamic selectable graduation application service that provides in public based on " paying by using ", and use various " then and there " payment means, such as credit card information, flight regular guest information, as temporary identifier information of accommodation number or the like, and do not need to the service provider of data supply predetermined in advance.
Other aspects of the present invention are to utilize such payment policies, promptly collect with them to the user and use oneself equipment to select the user's relevant with the service of visiting expense.Generally speaking, these payment policies are based on various standards, comprise the User Activity degree with the quantitaes of the communication stream that is transferred to this user and/or sends from this user, and the duration (Session Time) of the application service of selected grade perhaps is provided.And charging policy can dynamically change in session, thereby allows user's renewal or revise the his or her grade of service and payment policies.
Other aspects of the present invention and better understanding can be by realizing with reference to describing in detail.

Embodiment
The present invention is used for the methods, devices and systems that the user selects for providing between a plurality of application service tier that provide by public network visit architecture.It allows the visit of user's acquisition to the application service of such different brackets, even they subscriber that do not provide in advance and corresponding service provider concerns.It also allows user automatically Dynamic Selection and the application service tier of reselecting their expectation, and need not service provider operator's intervention.In certain embodiments, such variation also causes the machine-processed suitable variation of charge (or record keeping).
Among the present invention, service is defined as the purpose end points, such as: Lotus Notes mail server of the Web page or leaf of company, the application of the server of company, company or the like.This application level definition of service is different from the service of network-level, such as communicating the communication bandwidth that is allowed on the Internet, and for example 56Kbps or 128Kbps, this is what has nothing to do with the destination of communicating by letter.
In various embodiments of the present invention, the user can use themselves personal data appliances, as notebook or PDA(Personal Digital Assistant).The user also can use other computing equipment temporarily, as information kiosk (kiosk) etc.Yet, be purpose of the present invention, here those other equipment are assumed that showing fully is user oneself " daily " computing equipments as them, and do not require and be incorporated into any one group of so additional software or hardware component in these equipment, wherein these software and hardware parts are unique and make these equipment can professor according to the present invention go operation exclusively, and make their user can obtain the present invention professor's benefit.Consider that the service provisioning that is used for the embodiment of the invention is based on ubiquitous, IP-based technique of internet; Access technique is based on the wireless local communication technology that operates in the unauthorized radio band, such as IEEE 802.11b WLAN or blue teeth wireless PAN.Apparently, those skilled in the art can realize other embodiment of the present invention, and does not break away from spirit of the present invention and notion.For example, they can be with other optional access techniques, such as infrared ray or Ethernet, maybe can use dynamically by using the arrangement of paying as a kind of approach of charged extra application service tier that is used for visiting once in a while the grade of the acquiescence predetermined profile that does not belong to them based on predetermined client.
Fig. 1 show be used in the public domain such as the mobile subscriber that locates of the hotspot on airport (wireless hotspot) and their equipment the architecture of the system of wireless network access is provided.This figure has also given prominence to and need have been carried out step with the application service that obtains desired grade by the user.Accesses network 101 comprises router (as 106,107) and WAP (WiAP) (as 110,111).Subscriber equipment or user terminal (108), the wireless connections 109 that pass through to access point (110 among Fig. 1) are connected to this accesses network.Except network layer entities, outside access point and router, accesses network also can comprise network support service, such as DHCP (DHCP) server 102, DNS (domain name service) server 113 and web proxy (as 112,117).DHCP and DNS entity are the common assemblies in most of IP-based network well known by persons skilled in the art, and provide various configuration informations and query parse support for IP-based user terminal.Web proxy is used to manage the visit from the user terminal to the Web server.In the embodiments of the invention, accesses network comprises registrar 114, and it is used to interactively and sets up the desired application service tier of personal user.
As the example of the possible grade of distinguishing between application service tier, Fig. 1 shows two application service tier, gold service 103 and silver service 104.Each application service tier is by set (group) definition of one or more services.In this embodiment, the silver-colored grade of service 104 comprises the visit to general the Internet among Fig. 1 105.Except comprise all be included in the silver-colored grade of service all the service, the golden grade of service also may comprise the service that video clipping is provided to user terminal.The application service tier of these grades can exist statically, that is, for example silver-colored application service tier may comprise mutually same group application service (perhaps at least seldom being updated) within it always.On the other hand, the distribution of the application service in each grade can be dynamic, can be changed based on various standards to the application service in the grade by " distribution " here.In certain embodiments, measured combination increases or deducts service, such as based on: application service quality is considered; The control of enforcement access permission; Time; In the different time different charging mode or the like is used in the service of using.
Fig. 2 shows and is used to the present invention and allows the personal user to go to specify and obtain 3 functional steps to authorized application service visit.These 3 steps are:
A) registration, it allows the user specify their selection in obtainable application service;
B) control notice, it allows the actuating equipment of appointment know to be used for specific user's suitable access profile, and
C) carry out, it allows the suitable network equipment to go control each bag, connection or the session relevant with special user equipment, and is total corresponding with authorized application service to guarantee them.
Therefore, Fig. 2 has given prominence to the present invention and is used for providing step to the visit of each tier of application service to user terminal.Particularly, user terminal 108 at first registers 201 to registration body 202.Period of registration is except that other affairs, by unique identifier identifying subscriber terminal.This identifier during associated session, promptly when user terminal finishes it with the related of accesses network (101) and the application service that can obtain by it till, should be unique.Because accesses network can be selected dynamically Be Controlled, dispose and/or reshuffle, so the accesses network among Fig. 1 (101) also is designated controllable architecture in Fig. 2 based on its user's application service tier.This identifier can be fixed, medium access (MAC) address of the communication hardware subsystem that the picture user terminal uses, or interim, as distributing to the IP address of user terminal by Dynamic Host Configuration Protocol server, or offer the Web cookie that the Web browser that operates on the user terminal is used.By using not direct interface Network Based (as MAC Address) or based on the identifier of the specific configuration parameters that provides by the accesses network architecture (as the IP address), registration body allows user terminal to keep its related with registrar, even its network connection variation (as plugged new network interface, or DHCP has disposed new IP address).In these cases, user terminal can be shared the part responsibility and gives registrar with equipment or the change notification in the network specific configuration parameters about it.
Registration body 202 will write down the application service tier that this identifier and user terminal have been asked.Utilize these knowledge, registration body will regulate communication network to adapt to this new user and his selected application service tier.Regulate to move mainly to be included in the binding information between equipment mark symbol and the application service tier is passed in some or all nodes of may command visit architecture by system signal 203.As an example, registration body's (also claiming registrar) can:
A) MAC Address with user terminal passes to access point and lan switch together in company with application service tier, perhaps
B) the IP address with user terminal passes to network router together in company with application service tier, perhaps
C) Web cookie/IP address is passed to web proxy in the network together in company with application service tier, perhaps
D) notice specific to the server of using accept or refusal from the communication stream of specific user terminal.
Use this information, suitable network node block or let pass from user terminal to those services 205 or from those service 205 communication stream 206 to user terminal.
Fig. 3 shows the example of each step in user terminal and system initial mutual.It comprises such function, such as obtaining an IP address (116), the function of the application service tier (115) of contact registrar and selection expectation, and consequent control notice are upgraded as the state to general control architecture (117 and 203).This embodiment of the present invention uses standard DHCP agreement to be used to dispose personal user's terminal.After user terminal entered system, the Physical layer that its network connects was activated, and its system software is notified.As a result, user terminal is broadcasted DHCP request (items 1 in 301) on grid.This request is moved the machine processing of Dynamic Host Configuration Protocol server 102, and this machine sends it back a response (items 2 in 108 and 301) to user terminal.This dhcp response comprises the IP address of being given the machine of the IP address of this user terminal, the acquiescence IP addresses of nodes (gateway ip address) that is used for relay message and operation DSN server by system assignment.
Of the present invention one special embodiment has the client configuration software of having revised its default behavior.For example when using the DHCP agreement, the specific option of a system is added to the DHCP agreement, and this can finish according to the existing standard that is used for increasing at DHCP option, and has expanded Dynamic Host Configuration Protocol server and client software to produce and to explain this new option respectively.The specific DHCP option of system comprises the address of registrar.When handling dhcp response, the DHCP client software of expansion uses this address start to be directed to the browser of registrar 304.This foregoing description of the present invention represented a DHCP client-server software that uses expansion need not show the user terminal got involved of the user embodiment example of configuration automatically.In another embodiment of the present invention, do not realize expansion (302) to the DHCP agreement or to DHCP client-server software.After having handled dhcp response and having disposed the network connection, on user terminal, manually boot browser and this browser is directed to registrar.The sign of registrar can be used as ULR and obtains from the bookmark set of browser, maybe can for example can give prominence to the visual notice (303) of printing or showing in public by band outer (out-of-band) mechanism and offer the user.Although DHCP is the most general mechanism that is used for the user terminal initial configuration, can the same use other configuration protocol effectively.For example, Internet Protocol next generation, IPv6 allows node to dispose himself automatically, and need not any help from Dynamic Host Configuration Protocol server.And utilization is as the technology of destination redirection, and the Web request from client devices to destination Web can be redirected to any desired position, for example, and registrar, and be independent of the position of wanting at the browser client on the Internet.The present invention is same being suitable for to the means of this other optional initial user terminal configuration.
As a user and the mutual part of registrar, the user will then select the application service tier of expecting and provide and the relevant information (305) of paying.This information then is registered server/mechanism and sends to node suitable, that separate in logic and confirm (306).If it is correct (307) that the information that the user provides is identified, registration is considered to success.In this situation, initiate to be used for the record keeping process of this user conversation, and give general control architecture assembly (308) with suitable information relay by the control notification message.If this information is invalid (307), then generally provide other chance whereabouts system registry (310) to the user.
In case the successful authorised user's of system particular application services grade is selected, but then desired user is initiated to the transmission of the application service of this grade.Fig. 4 shows in an instantiation procedure, the step of being deferred to by an assembly of generic access may command architecture (204 among Fig. 2) in such communication process.After receiving bag (request package or any transmission) 401, check that this bag is to determine its source, i.e. user terminal, and the application service tier 402 under it from an equipment.The mechanism that this bag is associated with a specific user terminal and/or application service tier depends on the definite assembly of realizing this execution in the may command visit architecture.In Fig. 9, at the situation of WAP or web proxy this point has been described at the situation of router with in Figure 10.If application service meets and the relevant grade of service 403 in bag source, then this bag is transmitted to next jumping (hop) 404, and, if necessary, under the charging policy of this particular application services situation about requiring like this, upgrade and the related charging information 405 of source user terminal.If this application service does not meet 403, then or abandon this bag or take suitable remedial steps 406.In arbitrary in the above situation, this architecture assembly begins to handle next bag.If meet test crash 403, then system may wish to take other optional remedial measuress.
In certain embodiments, the enforcement node redirects bag, and/or generate failure notification to registrar.If fail bag by meeting test corresponding to a request based on Web, then registrar then can use http protocol with a push-notification-answer user terminal, this according to notice user's visit of attempting to carry out run counter to user's the current application grade of service.Should can offer the selection that the user consults application service tier again based on the notice of Web, and can not be rejected so that examination is repaid in the subsequent user visit.
The information that the time provided in registration by the user and the ability of system are provided, and another remedial action will be to send " band is outer " to the user to notify.When the user is current when not using Web browser to use or do not contain any system can be when it sends the proprietary application of message, back one situation is expected." band is outer " notice can be included in for example message transmission of radio individual equipment of beeper, interactively personal email equipment, to cellular call, and SMS (short message service) message or the like.
Next be described in public access network just carrying out related during, the user can consult or change the process of their application service tier again.As already explained, when the user finds outside the current current grade range of choice the user of application service of specific expectation, can use this process.Perhaps, at a time, the user also can find to switch to the needs of different application service tier temporarily.For example, the user may catch sight of the needs of the charged extra application service within the application service tier that visit is not included in initial selection.Note, create for the user sometimes and the application service profile of storage is pointed out under certain conditions or when for example location-based attribute of specific attribute is satisfied, the preferably selection of application service tier.User's service profile can help the selection of application service tier.
Though embodiments of the invention described herein are mentioned the user of services selection and selected, the use that is used for the service profile that convenient user gradation selects is not outside spirit of the present invention.Fig. 5 shows the step that comprises in the process that changes the application service tier related with user terminal.User terminal is got in touch registrar 501 by browser being directed to registrar, and request changes the current grade of application service (502), and the information 503 that is necessary (being similar to 305) is provided.If this information is effective 504, then change and be accepted, and the state 505 of the access control in the general architecture and 506 assemblies of keeping accounts is updated.Because user terminal has had existing and related (and therefore having unique identifier) accesses network, so that the process 503 that submits necessary information may not resemble the initial procedure 305 among Fig. 3 is detailed.For example, the user may not need to provide again personal information (for example, credit number); But the software on the user terminal can directly provide the identifier (for example by using Web cookie) specific to the user to give registrar, thereby the helping service device gets up this to the change request of the application grade of service and existing user network relationship.
Although the process of the update service described in Fig. 5 is represented one embodiment of the present of invention, other process also is possible and do not break away from spirit of the present invention.For example, those skilled in the art can comprise that with suitable being used to the registration page of the application service tier of the application service of being asked responds, and obtains same result by application service and the service provider who the user is pointed out expect.This back one scheme does not require that the user goes contact registrar in dominance ground to upgrade.But it has been realized and the identical net result of embodiment as shown in Figure 5.
Because the support to the application service of Dynamic Definition is an element of the present invention, should specify the mechanism that can stop service association.For example, this de-registration mechanism is being useful to the correct record keeping in the situation that the related duration charges to the user based on user network.Such mechanism also can be used for checking current use and bill information making about before continuation or stopping association by the user.Fig. 6 show when the closeall effectively session of user terminal and when stopping it to the visit of each network service in (possibility) of user terminal and the public access network final step in alternately.In the illustrated embodiment, user terminal is directed on the registrar 601 with browser, and the standard of use http protocol goes for the termination 602 of asking its session.As the part of this request, user terminal may be included in the unique identifier of setting up in the registration procedure specific to the user, sees 201 among Fig. 2.Then, registrar extracts suitable use statistics 603 from relevant actuating equipment, and provides this suitable use information 604 to user terminal.Based on this use information, the user will then determine 605 or the association of confirming them stops or continues to utilize this publicly available service infrastructure.If the user determines to continue, termination process so is suspended, and the user recovers his or his proper network visit.This mechanism offers the means of activity history that one of user investigates them simply and relevant expense.But if the user determines to stop their current related 605, then registrar will be carried out steps necessary and have relevant information to remove with this user in public access network.Registrar will at first send suitable control notification message 606 to actuating equipment, to forbid any other visit of this user terminal.The successful execution of such control messages has removed the unnecessary access control information in the actuating equipment effectively.It has also taken on the mechanism of preventing any follow-up undelegated access attempts.After sending this notice, registrar also will remove the movable information specific to the user (such as the unique identifier related with user's current sessions) from its internal table, and finish the process 607 that the user is suitably charged.Except the notice access control apparatus, registrar also will be notified Dynamic Host Configuration Protocol server 608, so that Dynamic Host Configuration Protocol server can suitably upgrade its table and discharge resource.
Fig. 7 shows another example embodiment that is used for managing and stopping session under the situation about stopping of need not taking action to user's dominance.In this embodiment, use the Web technology that is known as cookie to follow the tracks of the existence of user terminal in system.Fig. 7 has repeated the relative section of Fig. 1, has increased the conversation database 702 of the record 703 of the terminal in the saved system in addition.Particularly, along with distributing the 116IP address by Dynamic Host Configuration Protocol server 102 to user terminal, 114 1 new IP of server notification 701 registrar address has been assigned to user terminal.In one embodiment, registration process is input to this IP address in one " wait " pond of IP address.When this registrar of user capture had service now to register a new service, continue or to upgrade, this IP address will be from waiting for that the pond is removed.In another embodiment, registrar is associated this IP address with record 703 in the user session database 702.In any case, all notify registrar new IP address assignment.
New IP address assignment can really be given brand-new user terminal, perhaps gives to have the terminal of ongoing session.When back one situation may occur in for various reasons, such as temporary link 109 failures, subscriber equipment restarts, owing to move the variation of the WAP cause, access technique is from WLAN for example to wired Ethernet, to adjustment of blue tooth wireless technology or the like.Subscriber equipment can obtain to be different from previously used brand-new IP address.Yet the user may select still effectively payment policies.For example, the user may ask 30 minutes time block, and between 7 to 10 minutes of this time block communication disruption has taken place.In this case, this brand-new IP address should associatedly not be tied to brand-new session, but is used to upgrade the session information relevant with existing session.
In the embodiment that is shown in Fig. 7 and Fig. 8, this realizes by using Web cookie.Web cookie is that Web server sends to a bit of information with the Web browser of this server interaction.Web browser is stored in cookie this locality in the user terminal that is moving this browser.When each this particular Web browser visited again this particular Web server, this cookie was uploaded by this browser.This can be used for the visit of track user to the particular Web website.In the situation of present embodiment, when after user terminal is being distributed to its new IP address, visiting again registrar, can once more this cookie be offered registrar, and registration process can use this cookie extracting the conversation recording (if present) that is used for this user terminal, and correspondingly upgrades it.
In another embodiment, omitted the transmission of the new IP address from the Dynamic Host Configuration Protocol server to the registrar.The session data of the session of the new initiation of its permission or the session of just carrying out is registered server and exclusively handles.Why possible this is, is because Web server as registrar, except that cookie, can also extract a large amount of information relevant with user terminal, comprises its IP address.Yet, the IP address transfer in 701, perhaps rightabout similar address is to be used to confirm that the employed IP of client devices address is the method for the legitimate ip address that distributed by Dynamic Host Configuration Protocol server.
If Fig. 8 shows by registrar and follows to determine it to receive the embodiment of the step how cookie will carry out.If cookie is associated with movable/session of just carrying out, claim that then cookie is effective.For making cookie invalid, some incidents 807 all may work.For example, Dynamic Host Configuration Protocol server can an invalid IP address.This occurs in when being expired before the user terminal requests renewal of lease by related " lease " time of Dynamic Host Configuration Protocol server IP address allocated.Among the embodiment in Fig. 7, Dynamic Host Configuration Protocol server transmits this information by transmission " removing the IP address " message 704.The granularity of DHCP lease has stipulated that the accuracy of the accounting policy of " paying " can be how when using; For example, if lease is to provide in the mode that increased progressively in two minutes, select the user that pays based on her session persistence minute to be kept accounts so for using system 2 or 4 or 6 etc.If the user has selected to pay and pass by in 30 minutes with 30 minutes time block, then session also may be disabled.In the conversation recording 703 in Fig. 7, the conversation recording item of the time (paymentDuration) that the latter can cover according to the select time (paymentSelectionTime) of describing payment policies and/or by selected payment policies, or other relevant datas that are stored in this conversation recording calculate.The time possibility of selecting the time of paying and selecting the grade of service is consistent, but this is not general requirement.The various time intervals can be related with the grace period further to consider that the user disconnects the possibility of connection temporarily.These grace periods advantageously coordinate with Dynamic Host Configuration Protocol server, so that the IP address assignment that Dynamic Host Configuration Protocol server will not remove is given new user terminal, if server does not also upgrade its conversation recording.
Because the user moves and other reasons, fail as temporary link, subscriber equipment restarts, owing to the change of moving the WAP that causes, from WLAN for example to wired Ethernet, to adjustment of the access technique of blue tooth wireless technology or the like, of short duration connection may take place interrupt.By using cookie, wherein cookie is used as sometimes and can continues to be present in the Session ID that connects after interrupting, and the user can continue to visit the service of selected grade, and does not need to re-register to registrar.The use cookie that it sends when the user terminal access registrar, registrar can recover any session information that it needs, and interrupts regardless of the connection that is caused by many reasons.This ability often is called service roaming (service roaming).
Fig. 9 shows more details of carrying out access control about how by the router in the may command architecture 204 among the Fig. 2 that uses accesses network 101 among Fig. 1 or equivalence.In Fig. 9, suppose to use the DHCP agreement to distribute IP address 10.0.0.1 to user terminal 901; In other embodiment, this IP address may be different with subsequently IP address.In addition, suppose that the service provider has defined two application service tier, golden grade and silver-colored grade, it allows user capture to have the equipment of IP address 10.1.1.2 and 10.1.2.2 respectively.(a plurality of application service tier, wherein each grade has a plurality of tabulations of IP address and/or port numbers, and this vague generalization is simple and clear to those of ordinary skill in the art.) client computer is then by WAP 902 contact registration bodies 903, to specify its desired application service tier.Registration body 903 provides the Web page or leaf tabulation of the relevant charge with them of 904 all obtainable application service tier.The user then selects between the grade 909 (golden grade and silver-colored grade) of two application services and sends it back 905 these selections (in company with other personal certificates together) to registrar.Can be incremental with service packet for each application service tier, in other words, for example selects also feasible all services that can visit in the silver-colored grade of service of the golden grade of service.
Suppose that user terminal selected the silver-colored grade of service.One of the node that can carry out access control mechanisms is a router 906 therein.As shown in Figure 9, should based on the access control scheme of router can be by the application service tier that will ask based on user terminal and it one group of filtering rule of IP address send 907 routers to and realize.After receiving these filtering rules, router stores them in the local routing table 908 into.In Fig. 9, routing table shows that IP address 10.0.0.1 (the IP address of the user terminal of just discussing) can be provided by the application service that provides on the tcp port on the destination address 10.1.2.2 80.This is corresponding to the Web server that is used for the silver service; Therefore, related with IP address 10.0.0.1 user terminal only can be visited the silver service.
Execution mechanism also can for example WAP or the execution of web proxy place of other optional nodes in the accesses network architecture.These other selections have been shown among Figure 10, have supposed like before that therein user terminal has IP address 10.0.0.1.In addition, hardware (MAC) address of supposing the wireless device related with this user terminal is " MAC_ADDR_1 ".At first, as shown in the figure left side, registration body 1002 can pass to one or more WAPs (WiAP) 1005,1006 with one group of filtering rule 1003,1004.Because WAP comes distinguishing terminal by MAC Address, so the filter table 1007 in the WAP (1005 among Figure 10) will comprise the MAC Address (in this example, being " MAC_ADDR_1 ") of user terminal and purpose IP address and/or the port numbers that this group allows destination node usually.In addition, the figure shows the example that user terminal has therein been selected silver-colored tier of application service 1008 (destination address 10.1.2.2).
The right side of Figure 10 has shown when the situation when arranging that on web proxy 1009 filtrator is carried out access control.In this case, registration body 1002 will organize suitable filtering rule 1010 and pass to web proxy.Web proxy then is updated in the corresponding information in its filter table 1011.Should be appreciated that this is the application layer strobe utility in fact, because web proxy only intercepts from the communication stream based on the user terminal of Web.In this case, user terminal can or by network layer identifier, as IP address (be 10.0.0.1 in this example), or the identifier by application layer, gather as one of Web cookie, and identified uniquely.
Figure 10 shows when IP address (10.0.0.1) the identification user terminal of filter table 1011 by user terminal, and discerns the situation of the destination of this group permission by one group of URL (URL(uniform resource locator)).In this specific example, suppose that the user has selected with URL the relevant silver-colored tier of application service of http: // 10.1.2.2/sliver.html.URL(uniform resource locator) (URL) is the standard way of name on Web, discovery and searching object.
