With reference to Fig. 2, be policy control method embodiment one flow chart in the embodiment of the invention, below be elaborated by concrete steps:
201, user terminal sends to connect and sets up request message to IAD, and request is set up the data to data network and connected;
202, optional, IAD carries out access authentication and mandate to terminal, obtains user signing contract information and authorization message;
203, IAD is transmitted to connect and is set up request message to data gateway;
204, data gateway and certificate server are mutual, and the user is authenticated and authorizes, and data gateway can obtain service quality (QoS, Quality of Service) information, user configuration information of acquiescence etc. from certificate server;
205, data gateway determines whether to set up the policy control session according to the policy control pattern, if set up, then notification strategy controlled entity data connect establishment, and the policy control pattern that provides data to connect;
The policy control pattern of data gateway can be pre-configured, perhaps obtains from certificate server in step 204.
206, policy control entity issues corresponding policy control information and gives data gateway according to the policy control pattern of obtaining, and data gateway carries out QoS control and charges data stream according to this information;
Policy control entity can be learned the policy control method that data connect according to the policy control pattern that data gateway provided.For example, judge whether and to comprise incidents such as access technology type change, IAD change by data gateway notification strategy control event.When the policy control pattern is data gateway implementation strategy when control only, policy control entity according to demand, if desired then by data gateway notification event message.When the policy control pattern is also implementation strategy when control of IAD, then need according to demand, then not notify if desired by data gateway notification event message by IAD.
In addition, policy control entity also can pre-configured policy control pattern; Or/and according to self strategy, user profile, the information mode decision scheme control models such as data network of being visited.At this moment, in the step 205, data gateway does not need the decision strategy control model, also not needing provides the policy control pattern to policy control entity, which kind of policy control pattern policy control entity uses according to judgements such as configuration information, self strategy, user profile, data network information, and in the policy control information that step 206 issues, the policy control pattern that the notification data gateway is adopted.
207, data gateway is the data connection that user terminal is established to IAD, sends connection establishment response message to IAD, and indication connects to set up to be finished;
208, IAD determines whether to set up the policy control session according to the policy control pattern, if set up, then sends the policy control session and sets up request notification strategy controlled entity data connection establishment;
Wherein, the policy control pattern is to be pre-configured to be in IAD, perhaps in authorization message or user signing contract information, obtain by IAD, concrete grammar can be: in step 202, when IAD authenticated and authorizes terminal, IAD provided the policy control method of oneself supporting, for example, whether whether support policy is controlled, support local policy to strengthen, and whether supports local many IP policy control etc.Whether certificate server adopts policy control and adopts which kind of policy control method according to configuration or CAMEL-Subscription-Information decision, if do not need usage policy control, perhaps do not support, certificate server can be indicated not usage policy control of IAD in authorization message, perhaps do not authorize the policy control method of the indicated employing of IAD.When IAD does not provide the policy control method of oneself being supported, certificate server can be according to configuration or CAMEL-Subscription-Information, directly provide desired policy control pattern to IAD, if certificate server is not authorized any policy control pattern, IAD can not enabled policy control.
209, policy control entity issues corresponding policy control information according to the policy control pattern and gives IAD, and IAD carries out QoS control and charges data stream according to this information;
Policy control entity can be learned the policy control method that data connect according to the policy control pattern that is provided.For example, when the policy control pattern is the multiple gateway policy control, need be by IAD notification strategy controlled entity access technology type change incident, then policy control entity indicates IAD need notify access technology type change incident in step 209.

With reference to Fig. 4, be policy control method embodiment three flow charts in the embodiment of the invention, below be elaborated by concrete steps:
401, terminal sends and local the connection sets up request message to IAD;
402, IAD authenticates and authorizes terminal;
403, IAD determines whether carry out policy control according to the policy control pattern, if carry out policy control, then sends the policy control session and sets up request message to policy control entity, sets up the policy control session;
Wherein, the policy control pattern can be pre-configured on IAD, perhaps obtains from certificate server in step 402.
In step 402, IAD can be according to policy control ability and the certificate server consulting tactical control model of self, perhaps certificate server distributing policy control in authorization message, user signing contract information.
The policy control session is set up and can be carried the policy control pattern information in the request message to policy control entity, for example, IAD is that terminal is set up local the connection, distribute local ip address, indication policy control entity, policy control pattern are many IP policy control, local policy reinforcement or multiple gateway policy control etc.
Described many IP policy control pattern indication, when portable terminal uses the MIP agreement, support ambulant IP data to connect for one and have a plurality of IP address, comprise local Care-of Address and ownership place address, policy control entity need be done special processing to this class policy control information, for example, can use Care-of Address and/or ownership place address for the IP filter information of the policing rule in the policy control information that is handed down to IAD, the IP filter information that is handed down in the policing rule of data gateway is used the ownership place address.
If IAD is the support policy controlled function not, can ignore this step, i.e. step 403.
404, after policy control entity receives request message, carry out policy determination, and the distributing policy control information;
How policy control entity can set up the policy control session according to the policy control mode adjudging, and for example, during many IP policy control pattern, policy control entity obtains the local Care-of Address of connection in step 403, issue the policy control information based on Care-of Address;
405, IAD returns local connection establishment response message to terminal;
406, terminal uses the local IP address that obtained of connecting as Care-of Address, sends to connect and sets up request message to data gateway;
407, data gateway carries out access authentication and mandate to the user;
408, data gateway determines whether carry out policy control according to the policy control pattern, if carry out policy control, then sends the policy control session and sets up request message to policy control entity, sets up the policy control session;
Wherein, the policy control pattern can be pre-configured on data gateway, perhaps obtains from certificate server in step 407.
When obtaining in step 407, data gateway can be according to policy control ability and the certificate server consulting tactical control model of self, perhaps certificate server distributing policy control model in authorization message, user signing contract information.For example, in step 402, suppose not support policy control of IAD, perhaps do not need local policy to strengthen, then single gateway policy control pattern or non-local policy enhancement mode are used in the certificate server decision, with data gateway reciprocal process in, inform the policy control pattern that data gateway should use.
Described single gateway policy control pattern is meant that only data gateway is done policy control, and is corresponding, and multiple gateway policy control pattern has been meant that a plurality of gateways do policy control, comprises IAD, data gateway.
Described local policy enhancement mode is meant, during roaming, some oneself policing rule can be used in the roaming place, comprises safety regulation, charging regulation etc., implements by IAD or data gateway.
The policy control session is set up and can be carried the policy control pattern in the request message to policy control entity.
If data gateway is the support policy controlled function not, can ignore this step.
409, after policy control entity receives request message, carry out policy determination, and issue corresponding policy control information;
How policy control entity sets up the policy control session according to the policy control mode adjudging.The policy control pattern can be obtained in step 403 and/or step 408, if all comprise, then should be consistent.For example, when the policy control pattern is many IP policy control, the ownership place address that data gateway provides IP to connect in step 408, policy control entity issue based on the policy information of ownership place address and give data gateway, also can issue simultaneously based on the policy information of ownership place address and give IAD.
Step 410, data gateway return connection establishment response message to terminal, connect to set up to finish.
From this embodiment as can be seen, IAD and data gateway acquisition strategy control model, and the policy control pattern of being obtained sent to policy control entity, by policy control entity according to the policy control pattern, carry out policy determination, issue corresponding policy control information, carry out policy control, therefore, the consistency of policy control in can the implementation strategy Control Network.
Setting up scene by connection among the above embodiment is example, policy control method to functional entitys such as data gateway, IAD and policy control entities is described in detail, in following examples to connecting in the handoff scenario, each functional entity carries out policy control, and implementation strategy is controlled conforming method and is described in detail:
With reference to Fig. 5, be policy control method embodiment four flow charts in the embodiment of the invention, terminal inserts data network by former Access Network via data gateway, has set up the IP connection.Sometime, because occurrence positions moves, terminal need insert from target access gateway, still uses original IP address visit data net.Below switch to example with scene, introduce and how to carry out policy control according to the policy control pattern, concrete steps are as follows:
501, terminal sends to connect to target access gateway and sets up request message;
502, target access gateway carries out access authentication and mandate to terminal;
503, target access gateway determines whether to set up the policy control session according to the policy control pattern, if set up, then sends the policy control session and sets up request message to policy control entity;
Wherein, the policy control pattern can be that IAD obtains in authorization message or CAMEL-Subscription-Information, concrete grammar can be, in step 502, IAD provides the policy control method oneself supported, for example, whether support policy is controlled, if support policy control then can provide concrete policy control method, such as, whether support local policy to strengthen, whether support many IP policy control etc.Whether certificate server adopts policy control and adopts which kind of policy control method according to configuration or CAMEL-Subscription-Information decision, if do not need usage policy control, perhaps do not support, certificate server can be indicated not usage policy control of IAD in authorization message, perhaps, do not authorize the policy control method of IAD indication.When IAD did not provide the own policy control method of being supported, certificate server can be thought not support policy control of IAD.Perhaps, without negotiation, certificate server directly provides desired policy control pattern to IAD according to configuration or CAMEL-Subscription-Information.If certificate server is not authorized any policy control pattern, IAD can not enabled policy control.
504, policy control entity is set up the policy control session according to the policy control pattern, and issues corresponding policy control information;
505, target access gateway sends to connect to data gateway and sets up request message;
506, the connection of data gateway judgment data switches, if before set up the policy control session, then sends policy control session updates message to policy control entity;
507, policy control entity is according to the data link information after switching, and data gateway is given in the distributing policy control information;
508, data gateway has been set up new data channel, issues connection establishment response message and gives target access gateway;
509, target access gateway returns connection establishment response message to terminal, connects to set up to finish.
The data of being set up connect by target access gateway access data network.
As can be seen, when the data connection switches, policy control entity is according to policy control pattern pre-configured or that obtain from target access gateway, issue corresponding policy control information, carry out policy control, can the implementation strategy controlled entity and the consistency of IAD when carrying out policy control; Equally, according to the data link information after switching, acquisition strategy control model, perhaps pre-configured policy control pattern, can issue corresponding policy control information to data gateway, carry out policy control, can the implementation strategy controlled entity and the consistency of data gateway when carrying out policy control.In a word, among this embodiment, carry out data and connect when switching, can realize that each functional entity carries out the consistency of policy control.
With reference to Fig. 6, be policy control method embodiment five flow charts in the embodiment of the invention, terminal inserts data network by former IAD, has set up the IP connection.Sometime, because occurrence positions moves, terminal need insert from target access gateway, still use original IP address visit data net, below by this handoff scenario, introduce each functional entity and how to carry out policy control according to the policy control pattern, concrete steps are as follows:
601, terminal sends to connect by former IAD and sets up request message to target access gateway;
602, former IAD is transmitted the connection request message of terminal to target access gateway;
603, target access gateway carries out access authentication and mandate to the user;
604, forwarding contexts between former IAD and the target access gateway, promptly former IAD sends to target access gateway such as data link information of terminal;
605, target access gateway if desired, then sends the policy control session and sets up request message according to policy control mode adjudging needs policy control whether;
Target access gateway can by pre-configured or in step 603 or step 604 the acquisition strategy control model.
If not support policy control of target access gateway then can be ignored this step, i.e. step 605.
Pre-configured, perhaps the method for acquisition strategy control model is described with the several embodiment in front in the Certificate Authority process, no longer repeats.For the method for in step 404, obtaining, be suitable for belonging to together the IAD in a territory, former IAD is included in the policy control pattern of using and passes to target access gateway in the context, and target access gateway can be selected to use and original consistent policy control pattern.
And for the IAD that does not belong to same territory, because the policy control pattern is normally different, therefore can not carry out context transfer, and by target access gateway according to pre-configured or carry out alternately with certificate server, the acquisition strategy control model is with saving signaling.
606, policy control entity is set up the policy control session according to the policy control pattern, and target access gateway is given in the distributing policy control information;
607, former IAD sends and switches indication to target access gateway;
608, target access gateway sends to connect and sets up request message to data gateway;
If 609, data gateway had before been set up the policy control session, then send policy control session updates message;
Data gateway if desired can be according to the data link information, and whether the determination strategy control model changes, for example, can carry in the data link information between the territory switch or the territory in switching, whether access technology information such as changes.
610, data gateway is given in the control information of policy control entity distributing policy;
If after switching, used different policy control patterns, policy control entity can be learned the policy control pattern of new side by step 605, can notification data gateway policy control pattern change in step 610 simultaneously; Perhaps, not support policy control of target access gateway, data gateway selects to use certain policy control pattern according to preconfigured information, user signing contract information etc., for example, select the single gateway control model, and employed policy control pattern notification strategy controlled entity in step 609.
611, data gateway is finished data channel foundation, sends connection establishment response message to target access gateway;
612, target access gateway sends connection establishment response message to terminal.
As can be seen, be with the difference of a last embodiment, when the data connection switches, by context transfer the data link information is passed to target access gateway by former IAD, mutual by former IAD and target access gateway, can obtain the policy control pattern that will adopt, and send to policy control entity, policy control entity is according to the policy control pattern of pre-configured policy control pattern or target access gateway transmission, policy control is carried out in the distributing policy control information.Identical with a last embodiment, data gateway and policy control entity are mutual, can obtain the policy control pattern that will adopt, and by policy control entity according to the policy control pattern, issue corresponding policy control information, carry out policy control.In a word, under the described handoff scenario of this embodiment, can guarantee the consistency of the policy control means that each functional entity adopts equally.
Above policy control method is normally by policy control entity acquisition strategy control model, and sends corresponding policy control information according to the policy control pattern of obtaining, and carries out policy control.Be understandable that, also can be by the implementation strategy control alone of some network elements such as gateway, do not need the participation of policy control entity, for example, gateway can adopt pre-configured policy control pattern, perhaps from certificate server acquisition strategy control model, wherein, the policy control pattern comprises: do not enable the policy control pattern, perhaps enable a kind of concrete policy control pattern.When enabling, this gateway can also be selected to carry out determining concrete policy control pattern alternately with policy control entity, carries out policy control, more than to be described in detail, repeat no more.
