Abstract
The invention is in use for solving issues: too frequent to carry out synchronization operation, and too larger consumption of system resources. The method includes steps: (1) when detecting disconnection between access server and strategy control server, access server side sends connection request to the said strategy control server; (2) after connection is rebuilt, the said access server sends user information to the strategy control server in order to synchronize user information in strategy control server and strategy information in access server respectively.
Description
Technical field
The present invention relates to network field, particularly relate to method for synchronous, system and device in a kind of value-added service.
Background technology
Along with development of internet technology, Virtual network operator can provide increasing access bandwidth for the user.Bigger bandwidth can not only satisfy primary demands such as user web browses, E-mail, resource downloading, and also having possessed simultaneously for the user provides the VoIP (Voice over IP) that takies more bandwidth, the ability of VOD (video request program), IPTV value-added services such as (based on the interactive broadband network TVs of IP technology).
The said value-added service of this paper only refers to that the user passes through the business that the resource portal server is selected.
Value-added service mainly is to realize by the cooperation between policy control server and the BAS Broadband Access Server.Described policy control server is used to provide business game, to satisfy the demand of various value-added services.Described BAS Broadband Access Server is used for the strategy that the reception strategy Control Server issues, and it is come into force, to satisfy user's value-added service demand.
In conjunction with shown in Figure 1, the user uses the flow process of value-added service as follows:
After a, user inserted the Internet by BAS Broadband Access Server, user's the information of reaching the standard grade was sent to the policy control server by BAS Broadband Access Server, though this moment, the user did not use value-added service, had had the ability of selecting value-added service.
B, user can select the value-added service that needs (for example: video request program) on the resource portal server, after business is selected, resource portal server notification strategy Control Server issues corresponding strategies (tactful content comprises bandwidth, priority etc.) to this user, the user is reached can use this professional ability.The BAS Broadband Access Server that policy control server distributing policy inserts to the user.The access ability of BAS Broadband Access Server by upgrading the user, bandwidth etc. make the user have the ability (for example: can be smooth watch video request program) of selected business.
C, when user offline or initiatively arrive resource portal server cancellation when professional, policy control server notification BAS Broadband Access Server is deleted this user's business game.
From above-mentioned flow process as seen, can the value-added service selected of the user key that normally begin and finish be that user's information will have record on the policy control server.Be that user profile in the policy control server will consistently with the user profile of BAS Broadband Access Server just can make issuing and delete normally and carrying out of strategy, and ensure the normal use of various charging ways.
Policy distribution between policy control server and the BAS Broadband Access Server and the main agreement of using of strategy deletion have COPS (Common Open Policy Server (vlan query protocol VLAN that is used for exchanging policy information between strategic server and client device)), Radius (Remote Authentication Dial In UserService remote customer dialing authentication system), SNMP (Simple Network Management Protocol Simple Network Management Protocol) etc.These several agreements basically identical on handling process, this paper is example with the COPS agreement.
Prior art one: when the user reached the standard grade, BAS Broadband Access Server was informed this user profile of policy control server, and when this user offline, informed that the policy control server deletes this user profile.
But under abnormal conditions, for example: the COPS between policy control server and the BAS Broadband Access Server connects when disconnecting, the policy control server can be deleted all user profile that the BAS Broadband Access Server that disconnect to connect was once uploaded, after rebuliding the COPS connection, the policy control server need not any processing, and it needs to wait for that new user's information of reaching the standard grade gets final product; When described COPS connects disconnection, all subscriber policys that BAS Broadband Access Server meeting deletion strategy Control Server issues, the purpose of doing like this is to prevent to disconnect during the connection, the user can't stop value-added service, or charges unusually.
But this programme is after policy control server and BAS Broadband Access Server reconnect, and online user's user profile can not informed the policy control server once more.Therefore online user selects value-added service just must reach the standard grade again if rethink.
Prior art two: after setting up being connected between policy control server and the BAS Broadband Access Server, regularly relatively whether list item is consistent.
For example: referring to shown in Figure 2, use the COPS agreement to connect between the described server, then can use synchronous flow process (SSQ, REQ and the SSC) message in the COPS agreement, realize that user profile writes down conforming inspection.
In the COPS agreement, the policy control server is responsible for issuing service strategy content as the COPS server end; BAS Broadband Access Server is responsible for strategy request and is realized business game as the COPS client.
When the user reaches the standard grade, the client announcement server user information of reaching the standard grade, use ClientHandle (the data object in the COPS agreement in the COPS agreement, session of handle object unique identification) object is as this user ID, in the process of selection or deletion value-added service, client and server all uses the index of Client Handle as user profile after the user.
When arriving the duration of setting, the policy control server is sent out synchronization request message (SSQ) and is given BAS Broadband Access Server at every turn; BAS Broadband Access Server is resolved described SSQ, judging whether there is user ID among the Handle among the described SSQ, if there is not user ID, and all users' information synchronously then.
BAS Broadband Access Server is sent out all users' REQ message to the policy control server; After the policy control server is received REQ, judge its unwritten user profile, and respective record.
All users with EOS after, BAS Broadband Access Server sends out end message (SSC) synchronous; After the policy control server is received SSC, finish originally subsynchronous.
But use sync message to realize the synchronous of user profile when the user is a lot, speed is slower.But this programme every certain time length synchronously once, so system resources consumption is bigger.

Policy distribution between policy control server and the BAS Broadband Access Server and the main agreement of using of strategy deletion have COPS, Radius, SNMP etc.These several agreements basically identical on handling process, this paper is example with the COPS agreement.
S1, user reach the standard grade, and begin to detect connection status.
After the user inserts the Internet by access server, described access server writes down this user's the information of reaching the standard grade, and send to the policy control server with the information of reaching the standard grade that COPS between the policy control server is connected this user by it, the user profile that described policy control server record is received (, having had the ability of selecting value-added service) though this moment, the user did not use value-added service.Simultaneously access server detects COPS connection status between itself and policy control server by detecting unit.
The user can select the value-added service that needs (for example: video request program) on the resource portal server, after business is selected, resource portal server notification strategy Control Server issues corresponding strategies (tactful content comprises bandwidth, priority etc.) to this user, the user is reached can use this professional ability.The access server that policy control server distributing policy inserts to the user.The access ability of this access server by upgrading the user, bandwidth etc. make the user have the ability (for example: can be smooth watch video request program) of selected business.
S2, detect and connect to disconnect.
When abnormal conditions occur, between described access server and the policy control server be connected disconnection the time, the state value that described detecting unit can detect the COPS connection status changes to disconnection.
S3, notice rebulid connection.
After described detecting unit detects described COPS connection disconnection, notify described access server to resend connection request to the policy control server; All subscriber policys that the deletion strategy of access server meeting simultaneously Control Server issues, the purpose of doing like this are to prevent that the user can't stop value-added service during the disconnection connection, or it is unusual to charge, with the accuracy of guarantee user charging.
After the policy control server is received connection request, set up COPS with access server again and be connected.
S4, access server active upload user profile.
After described COPS connection rebulids, access server is collected the user profile of reaching the standard grade of this access server record by described collection transmitting element, and the user profile that can use the user of value-added service is carried in the REQ message, by described collection transmitting element active upload to the policy control server.
S5, policy control server are finished synchronously.
According to current mechanism, after described connection disconnected, the policy control server can be deleted and disconnect all user profile that the access server that connects was once uploaded.
After described policy control server is received the user profile that access server uploads, the user profile of receiving is all write down (promptly finish policy control server side synchronously).
S6, access server are finished synchronously.
Because access server is initiatively uploaded user profile to the policy control server by described collection transmitting element among the step S4, this operation simulation user's sight of reaching the standard grade once more.So when the user selects value-added service once more under situation about not rolling off the production line, the policy control server will be received the instruction of resource portal server, and according to the user profile of its record, once more to the corresponding distributing policy information of access server.
After described access server is received the policy information that issues, policy information is corresponding respectively with the user profile of its record, finish the synchronous of access server.
By enforcement of the present invention, need not regularly synchronously, only need to initiate connection request again by access server, and finish synchronous detecting when being connected disconnection between access server and the policy control server.Thereby reduced the consumption of system resource.
Obviously, those skilled in the art can carry out various changes and modification to the present invention and not break away from the spirit and scope of the present invention.Like this, if of the present invention these are revised and modification belongs within the scope of claim of the present invention and equivalent technologies thereof, then the present invention also is intended to comprise these changes and modification interior.
