Description
Technical field
The present invention relates to the networking telephone (VoIP, Voice over IP) technology, refer to a kind of method and system that voip conversation discharges that trigger especially.
Background technology
The networking telephone (VoIP, Voice over IP) is the technology of a kind of internet usage agreement (IP) in the enterprising lang sound transmission of network, is the focus of the concern of present vast operator.
Fig. 1 is existing a kind of structural representation of supporting to carry out the network of VoIP business, shown in 1 figure, terminal is connected to IAD by the base station, resident data channel function (DPF on the IAD, Data Path Function), authentication device entities such as (Authenticator), its effect is to come exchanges data between the support terminal and the external world as the aggregation node of communicating by letter between terminal and the external world, and assists aaa server to realize the authentication of terminal etc.
Authentication and authorization charging (AAA, Authentication, Authorization and Accounting) server is the critical facility in the communication network, be used to realize control and the management of Virtual network operator, authentication, mandate and account service are provided data, user.
VoIP server (Voice over IP Server) is the node that network is used to carry out the VoIP business, comprise that session initiation protocol (SIP, the Session Initial Protocol) registration, the use SIP that are responsible for maintenance terminal set up voip conversation and be responsible for Media Stream (VoP) transmission, media format conversion etc. in conversation procedure between calling terminal and terminal called.Between VoIP server and IAD and the AAA service station interface is arranged all.And the interface between aaa server mainly comprises: from aaa server obtain terminal user account information with support to terminal use the VoIP business mandate, with the information such as state of aaa server interactive terminal about the VoIP business.
Two terminals shown in Figure 1 (being terminal 1 and terminal 2) refer to caller and terminal called respectively, and they are registered to respectively in separately the VoIP service; These two VoIP servers all are connected on the IP network (as, Internet net), terminal 1 and terminal 2 respectively by IP network carry out each other signaling and the exchange of media data.
Two IADs shown in Fig. 1, two VoIP servers, two aaa servers also can be same equipment, such as belonging to an operator at two terminals, and when being registered on the same VoIP server.
Prepaid accounting is called online charging again, is a kind of important Core Feature in the communication system, as shown in Figure 1, prepayment client (PPC, Prepaid Client) and prepaid server (PPS, Prepaid Server) are to support two essential functional entities of online charging, both charge to user's online to finish in cooperation, wherein, PPS can close with aaa server and establish, and also can set up separately with aaa server, when setting up separately, between aaa server and the PPS interface is arranged; General and the anchor point authentication device (Anchor Authenticator) of PPC closes and establishes, and promptly PPC is positioned at IAD.
PPS is used for the user account remaining sum is converted into the quota (this quota is meant the spendable data traffic of user, the spendable duration of call of user etc.) of some, then the part in the quota is distributed to terminal, and is notified PPC with this part quota; PPC then is used for coming the monitoring user business according to the quota that acquires, and when this part quota was about to use up, PPC can ask PPS to reallocate a part of quota to terminal.So repeatedly, all remaining quotas are all distributed to terminal, and this quota of notice PPC is the final quota of terminal until last PPS.When PPC detects above-mentioned last remaining quota and exhausts, PPC attempts to ask PPS allocation quota outward more for the last time, if this moment, PPS does not have quota again and can distribute, then in giving the receiveing the response of PPC, do not carry the information of distributing remaining sum, PPC subsequent triggers terminal exiting network.
In the prior art, operator uses the mode of chargeing by the duration of call usually, come the terminal use who uses the VoIP business is chargeed, and have two places can supply the execution point of operator's arrangement to the VoIP service billing: wherein a place is: will carry out a little being placed in the execution point to other service billings (as the Internet access service is chargeed), and promptly be placed among the PPC; Another place is: should carry out a little being placed on the VoIP server separately, and make it to separate with execution point to other service billings.If adopt above-mentioned second kind of setting, when terminal was used VoIP business and other professional (as Internet access service) at the same time, PPC was used to carry out the charging to other business, and the VoIP server is used for the VoIP business is chargeed.
If adopt first kind of setting, according to prior art, if current terminal use meets with in the process of using the VoIP business that Sorry, your ticket has not enough value or exhausts, PPC can triggering terminal move back net, yet the VoIP server of this terminal but can not get corresponding notice, cause it to think that current voip conversation also normally carrying out, and before predefined timer expiry, can not initiate to interrupt session, cause the wasting of resources; If adopt second kind of setting, if the current VoIP business of using of terminal use is also being used other business (as from the Internet data download) simultaneously, at this moment, the latter's charging is carried out by PPC; When the latter exhausted the user account remaining sum, PPC can triggering terminal move back net, and was same, this moment, the VoIP server of this terminal was not notified accordingly yet, cause it to think that current voip conversation also normally carrying out, and before predefined timer expiry, can not initiate to interrupt session.At this moment, except causing the wasting of resources, also can cause of the charging inaccurate (chargeed a period of time the expense that cause user need pay this extra should not pay) of VoIP server to the terminal use more.
At the VoIP business, after predefined timer expiry, the VoIP server can interrupt this session with anomalous mode.At this moment, for for the conversation distant terminal user of this terminal, will experience bad business experience (lose the other side's voice suddenly, and can not get any prompting); The more important thing is, just as not initiatively on-hook (release session) of above-mentioned distant terminal user, then before above-mentioned VoIP server does not interrupt session, this distant terminal user is still chargeed by the operator at its place, has caused inaccurate to this terminal use's charging equally.
In addition, in the prior art, it is a kind of very useful function of communication network that hot line is hung up (Hotlining).When the user in the business of using network to provide, when making a phone call, when the abnormal conditions outside the experience expection, mistake, such as subscriber arrearage, when crossing service area etc., hot line is hung up will temporarily block the business that the user is using, and notify the user to go to solve a question at the front by certain mode (such as on terminal, ejecting webpage, perhaps note).After the user has solved current mistake (such as supplementing, come back to service area etc. with money), hot line is hung up the intercepted business of recovering again, guarantees the continuous of customer service.
Equipment (HLD, Hotlining Device) hung up by hot line and hot line is hung up two important entities that application (HLA, Hotlining Application) is a support hot line hang-up function.Wherein, HLA is used for according to predefined rule, and when detecting that terminal (user) is current certain mistake or abnormal conditions to occur, trigger network is carried out hot line to the user and hung up.HLA generally and between aaa server has interface, and HLA uses this interface to send and the relevant instruction of hot line hang-up function to network by aaa server; HLD is used for concrete the execution hot line of terminal is hung up, HLD generally be placed in IAD or home agent (HA, HomeAgent) in.In the prior art, when HLD began terminal session carried out hot line and hang up, HLD abandoned or is forwarded to HLA with the data of all sessions that belongs to this terminal (IP packet), was the particular content of being indifferent to this IP packet.
When the terminal use used VoIP business and other professional (such as data service, positioning service) at the same time, mistake or abnormal conditions had taken place in any one business as long as have wherein, and HLA may carry out the hot line hang-up to the session of terminal by trigger network.In case the session of terminal is hung up by hot line, the VoIP business that terminal is being used also will be blocked, at this moment, will cause moving back the same a series of problems that cause when netting with the PPC triggering terminal, promptly cause the wasting of resources, VoIP server to charging of terminal use inaccurate (chargeed a period of time more, caused subscriber arrearage) etc.
Insert (WiMAX in worldwide interoperability for microwave, Worldwide Interoperability for Microwave Access) in the network, the above-mentioned VoIP server WiMAX VoIP service server (WVS Server, WiMAX VoIP Service Server) that is otherwise known as.

Step 200: terminal room is using voip conversation.
The specific implementation of this step belongs to prior art, can repeat no more here with reference to related protocol.
Step 201: when satisfying trigger condition, network side notice VoIP server initiates to discharge the voip conversation of terminal room.
Trigger condition in this step is meant: aaa server is found to need quota application, exhausts such as the spendable data traffic of user, the spendable duration of call of user etc., in other words is exactly subscriber arrearage or Sorry, your ticket has not enough value etc. needs quota application.
Network side in this step can be the aaa server of terminal, or the anchor point authentication device of terminal.When network side was the aaa server of terminal, aaa server sent session to the VoIP of terminal server and discharges Indication message when judging described terminal arrearage or Sorry, your ticket has not enough value; The VoIP server initiates to discharge the voip conversation of described terminal room.Wherein aaa server receives the quota that the indicating terminal quota exhausts and exhausts Indication message, is confirming do not have extra quota can divide timing, judges the terminal arrearage or Sorry, your ticket has not enough value.When network side was the anchor point authentication device of terminal, the anchor point authentication device was received after the indication of prepayment client (PPC), sends session to described VoIP server and discharges Indication message; Described VoIP server initiates to discharge the voip conversation of described terminal room.Here, PPC receives the confirmation quota that terminal quota exhausts and exhausts indication and reply, and after obtaining the sign of VoIP server of terminal, PPC transmits described indication to the anchor point authentication device, carries the sign of VoIP server in indication.
Further, if when terminal room uses voip conversation, terminal is also being carried out other business, such as from Internet data download etc.When this business makes a mistake, reach flow in limited time such as from the Internet data download time, network side can trigger and use the hot line of the session of other professional terminal to hang up to this.At this moment, the inventive method also comprises: network side notice VoIP server initiates to discharge the voip conversation of terminal room, belongs to prior art about the hot line of terminal is hung up, and what emphasize is hot line to take place hang up this condition.Here, network side can be an aaa server, or HLD.
Notice VoIP server among the present invention initiates to discharge the voip conversation of terminal room, can be to send session to the VoIP server to discharge indication, and at this moment, the VoIP server discharges the voip conversation of terminal room as indicated; Also can be to send terminal to the VoIP server will enter the state that moves back net or hang-up, at this moment, the VoIP server discharges the voip conversation (terminal is the state that moves back net or hang-up) or the voip conversation between the held terminal (state of terminal for hanging up) of terminal room according to the state of terminal.
Further, after the voip conversation between VoIP server held terminal, when network side triggering cancellation was hung up the hot line of terminal, aaa server or HLD gave the VoIP server with the state notifying that terminal is recovered normal talking, and the VoIP server recovers the voip conversation of terminal room.
Further, the inventive method also comprises: VoIP server notification aaa server stops the charging to the VoIP business of terminal.
Before terminal room used networking telephone voip conversation, the inventive method also comprised:
Endpoint registration is to the VoIP server of terminal; When satisfying trigger condition, network side can also be that notice VoIP server initiates to nullify terminal.
At the inventive method, also provide a kind of system that voip conversation discharges that triggers.Fig. 3 as shown in Figure 3, mainly comprises network side, VoIP server for the present invention triggers the composition structural representation of the system that voip conversation discharges, and terminal, wherein,
Terminal is used to use voip conversation.
Network side is used to receive and satisfies trigger condition information that notice VoIP server initiates to discharge the voip conversation of terminal room.Network side can be the aaa server of terminal, or the anchor point authentication device of terminal.
The VoIP server is used to receive the notice from network side, initiates the process of the voip conversation of release terminal room.
Described terminal also is used to carry out other service concurrence and gives birth to mistake, and the professional session of other of its use is suspended.
Network side also is used to receive service error information, uses the session of other professional terminal to carry out the hot line pending operation to this.Network side can be an aaa server, or HLD.
The VoIP server, the session that specifically is used to receive from network side discharges indication, discharges the voip conversation of terminal room as indicated; Perhaps receive terminal and will enter the state that moves back net or hang-up,, discharge the voip conversation of terminal room or the voip conversation between the held terminal according to the state of terminal.
Described VoIP server also is used for after the voip conversation between the held terminal, when network side triggering cancellation is hung up the hot line of terminal, receives the notice from the state of normal talking that terminal is recovered of aaa server or HLD, and recovers the voip conversation of terminal room.
Described VoIP server also is used to notify aaa server to stop charging to the VoIP business of terminal.
Below in conjunction with embodiment method of the present invention is described in detail.
Fig. 4 triggers the schematic flow sheet of first embodiment of voip conversation release for the present invention, among first embodiment, suppose carrying out VoIP speech business (making a phone call) between calling terminal (terminal 1) and the terminal called (terminal 2), at this moment, suppose the account balance deficiency (remaining sum uses up) of terminal 1, initiate to discharge this voip conversation by the VoIP server (VoIP server 1) of aaa server (aaa server 1) triggering terminal 1 of terminal 1, as shown in Figure 4, specifically may further comprise the steps:
Step 400: the VoIP business of enlivening between terminal 1 and the terminal 2 (making a phone call).Media Stream between terminal 1 and the terminal 2 and signaling send to the other side by VoIP server (being respectively VoIP server 1, VoIP server 2) separately.This step is a prior art, and specific implementation repeats no more here.
Step 401: the PPC of terminal 1 detects the quota that current PPS distributes to terminal 1 and uses up.
Step 402: the PPC of terminal 1 sends quota to the PPS of terminal 1 and exhausts Indication message, and this quota exhausts Indication message and represents that terminal 1 current quota exhausts, and this message also is used for PPC to the possible Ex quota of PPS request.
Need to prove that if PPS and aaa server set up separately, then PPC at first exhausts Indication message with quota and sends to aaa server, and then is forwarded to PPS by aaa server.
Wherein, join that to exhaust Indication message can be AAA message between PPC and the aaa server, such as, when using RADIUS message, above-mentioned quota exhausts corresponding request (Access-Request) message that inserts of Indication message.
Step 403:AAA server (or PPS) receives after the message that confirming does not have extra quota to distribute.At this moment, aaa server (or PPS) judges the account arrearage of this terminal (user) or Sorry, your ticket has not enough value (remaining sum is 0, and perhaps Sorry, your ticket has not enough value to support an allocation of quota again).
Above-mentioned steps 400～step 403 is a prior art, and specific implementation belongs to those skilled in the art's conventional techniques means, repeats no more here.
Step 404:AAA server sends session to the VoIP of terminal 1 server 1 and discharges Indication message, is used to trigger the voip conversation that VoIP server 1 is initiated between two terminals of release (terminal 1 and terminal 2).This step specific implementation comprises:
At first, aaa server finds VoIP server into this Terminal Service according to the sign of terminal 1, confirms that simultaneously current terminal 1 using the VoIP business; Then, according to the sign of the VoIP server that finds such as IP address etc.,, send session and discharge Indication message by the interface between aaa server self and this VoIP server.
When the interface between aaa server and the VoIP server was based on the interface of aaa protocol, session discharged Indication message corresponding to an AAA message.Such as, when adopting radius protocol (RADIUS is a kind of of aaa protocol), aaa server can send change to VoIP server 1 and authorize (CoA, Change of Authorization) message or chain rupture request message (Disconnect Request) sign of carried terminal 1 in above-mentioned message, and this VoIP server 1 of expression request initiates to discharge the indication of the voip conversation relevant with terminal 1.
Wherein, the sign of terminal can be terminal use's a network access Identifier (NAI, Network Access Identity), also can be the service identification that the terminal use is used to use the VoIP business.Especially, in the WiMAX network, the VoIP server is WVS Server.
Further, terminal 1 is using the VoIP business not only can refer to the voip conversation of carrying out mentioned above, can also refer to terminal 1 and registered (login) to VoIP server (before carrying out voip conversation between terminal 1 and the terminal 2, terminal 1 and terminal 2 all at first need to be registered on separately the VoIP server).Then the inventive method not only can be used for aaa server indication VoIP server release session, can also be used to indicate the VoIP server to nullify (Deregister) terminal 1.At this moment, the inventive method also comprises: can issue at aaa server increases corresponding indication in the message of VoIP server; If terminal 1 only is registration (login) to the VoIP server, and do not carry out voip conversation, then aaa server indication VoIP server is nullified this terminal, can use corresponding the cancellation to indicate in aaa server is issued the message of VoIP server this moment.
Step 405:VoIP server 1 receives that session discharges after the Indication message, initiates to discharge the voip conversation of terminal room.Particularly:
VoIP server 1 is by sending session release message such as SIP BYE message to VoIP server 2, perhaps miscue information, and then the session release message of receiving is sent to terminal 2 by VoIP server 2, to realize release to the voip conversation of 2 at terminal 1 and terminal.Preferably, can also further broadcast prompt tone, with the reason of informing that terminal 2 sessions discharge to terminal 2.
After terminal 2 was received session release message or miscue information, terminal 2 was carried out the on-hook operation; The network at terminal 2 places stops the charging to the VoIP business of terminal 2 simultaneously.
Need to prove and since this moment terminal 1 place network may begin to trigger and make terminal 1 move back the flow process of net (anchor point authentication device/PPC triggers), cause the link between terminal 1 and the VoIP server 1 to be released.Therefore, VoIP server 1 can be attempted sending session release message or miscue message to terminal 1 at this moment, also can ignore to terminal 1, specifically adopts which kind of mode to depend on concrete local policy.
VoIP server 1 can also initiate to nullify terminal 1.The method that the VoIP server is registered to the terminal on it belongs to prior art, and specific implementation belongs to those skilled in the art's conventional techniques means, does not repeat them here.
Step 406:VoIP server 1 notice aaa server 1 stops the VoIP service billing to terminal 1.Such as, VoIP server 1 sends to charge to aaa server 1 and stops request.
As indicated above, operator can be placed in the execution point to the VoIP service billing on the VoIP server.At this moment, the charging that the VoIP server need notify aaa server to finish terminal is used the VoIP business stops request as sending to charge.If the accounting server to the VoIP service billing is not an aaa server 1, then VoIP server 1 can stop request message with above-mentioned charging and sends on the accounting server.
Step 407:AAA server 1 stops terminal 1 is used the charging of VoIP business, simultaneously to VoIP server 1 echo reply message.Such as, aaa server 1 returns to charge to VoIP server 1 and stops response message.
Preferably, in step 406 and step 407, the charging of dialling in the service for checking credentials (RADIUS, Remote Authentication Dial In User ServiceProtocol) protocol definition by remote subscriber between VoIP server and the aaa server stops request (Accounting-Request (Stop)) and charges stopping to reply the charging that (Accounting-Response (Stop)) interacting message finishes terminal and stopping.
Above-mentioned steps 406 and step 407 can with step 405 executed in parallel.
Need to prove that if be aaa server to the accounting server of VoIP service billing, so, step 406 and step 407 not necessarily need to carry out; But in step 404, aaa server self directly stops the charging of VoIP business is got final product.
Step 408:VoIP service 1 aaa server 1 to terminal 1 returns session and discharges and reply, and replys (CoA-ACK) message or (Disconnection Response) replied in chain rupture such as CoA, notice aaa server 1, and its voip conversation finishes.
Above-mentioned steps 408 with step 405, step 406 can executed in parallel.
Step 409: the aaa server 1 of terminal 1 to the PPC of terminal 1 return quota exhaust the indication reply.As mentioned above, when using RADIUS message between aaa server and the PPC, can use here and insert response (Access-Response) message.PPC receives after this message, can triggering terminal 1 execution move back net.
Above-mentioned steps 409 can executed in parallel with step 404～step 408.
From the method for first embodiment as can be seen, to under the scene such as carry out voip conversation terminal generation arrearage, Sorry, your ticket has not enough value, aaa server sends session to the VoIP of terminal 1 server 1 and discharges Indication message, in time discharged the voip conversation of terminal room, avoided the inaccurate charging of the waste of resource and VoIP server the terminal use.
First embodiment is the example at terminal 1 resource exhaustion (arrearage, Sorry, your ticket has not enough value etc.).In first embodiment, might not require terminal 1 is the calling party, and terminal 1 also can be the callee.Same method also can be applied in the example that terminal 2 quotas exhaust, and its realization flow principle is identical, repeats no more here.
Fig. 5 triggers the schematic flow sheet of second embodiment of voip conversation release for the present invention, among second embodiment, suppose carrying out VoIP speech business (making a phone call) between calling terminal (terminal 1) and the terminal called (terminal 2), at this moment, suppose the account balance deficiency (remaining sum uses up) of terminal 1, VoIP server (VoIP server 1) by the anchor point authentication device of terminal 1 (close establish with the PPC of terminal 1) triggering terminal 1 initiates to discharge this voip conversation, as shown in Figure 5, specifically may further comprise the steps:
The specific implementation of step 500～step 503 and step 400～step 403 in full accord no longer repeated here.
Step 504: the aaa server 1 of terminal 1 returns quota to the PPC of terminal 1 and exhausts indication and reply, and exhausts (user account arrearage, Sorry, your ticket has not enough value etc.) in order to the quota of confirming terminal.Shown in step 409, when aaa server initiate and PPC between when adopting radius protocol, aaa server can use and insert response (Access-Response) message and come to return quota to PPC and exhaust indication and reply.
Step 505: the PPC of terminal 1 closes the anchor point authentication device (Anchor Authenticator) of the terminal 1 of establishing in this locality notice (indication) after receiving that quota exhausts the indication response message with it.
In this step, the anchor point authentication device at first obtains the sign of the VoIP server of terminal 1, such as, in step 504, aaa server sends to PPC with the sign (as the IP address) of this VoIP server, and then is notified to the anchor point authentication device in this locality by PPC.When using radius protocol, insert the sign that response message can be used to carry this VoIP server.
Preferably, only when confirming that current terminal 1 is using VoIP professional, just the sign with the VoIP server sends to PPC to aaa server.
