Introduce the present invention in detail below with reference to accompanying drawing, wherein:
Fig. 1 exemplarily shows the network carrying structure of VOIP business;
Fig. 2 exemplarily shows the basic procedure of a kind of VOIP business in the prior art;
Fig. 3 exemplarily shows the basic procedure according to VOIP service log-on process of the present invention.
Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with the referenced drawings preferred embodiment.
Fig. 1 exemplarily shows the network carrying structure of VOIP business.As shown in Figure 1, the network configuration of execution VOIP business mainly comprises soft-switch platform, traffic border control appliance (BAC), home gateway, SIP phone and software terminal.Wherein, soft-switch platform mainly carries out professional authentication, authentication and call treatment etc.The traffic border controller passes through and Media proxy etc. mainly as the signaling fire compartment wall of soft switch service, private user.Home gateway mainly is responsible for finishing network access facility.SIP phone and software terminal belong to service terminal, the initiation of responsible VOIP service call and response etc.
Fig. 2 initiates with SIP phone or built-in Integrated Access Device function bridge connected home gateway that call is the basic procedure that example shows VOIP business in the prior art to common public switched telephone (PSTN).
As shown in Figure 2, whole process can be divided into three phases: network insertion stage, service log-on stage and call phase.
At first need to prove, before making a call, in the application terminal, write relevant configuration information.For example can in the application terminal, write relevant configuration information in the following manner:
A writes relevant configuration information in the business hall by operator in the application terminal when user applies is professional, comprise registrar information;
B informs user's relevant configuration information by operator, comprises registrar information, is configured on terminal by the user then;
If the c application terminal can accomplish to be managed by the relevant terminal management system, the corresponding information that then only need unify the configurating terminal managerial demand on the application terminal by operator, after reaching the standard grade in the application terminal, terminal management system can write the needed relevant configuration information of corresponding service automatically, comprises registrar information.
Below with reference to Fig. 2 the flow process with VOIP business in the prior art is elaborated.
In the network insertion stage, the request of PPPoE access authentication is at first initiated in application terminal (for example SIP phone), the PPPoE request ends in Broadband Remote Access Server (BRAS) through home gateway transparent transmission (if route formula home gateway, then PPPoE is initiated by home gateway).Then, BRAS initiates authentication request to RADIUS (remote authorization dial-in customer service) server; Radius server allows to insert, otherwise returns the authentication response that refusal inserts carrying out account number and password authentification by back return authentication response.
Then, in the stage, the register requirement (Register) to flexible exchanging network is initiated in the application terminal at service log-on.Because the registrar that disposes on the application terminal is BAC,, then register requirement is transmitted to Softswitch (SS) so BAC receives register requirement.SS carries out the response that register requirement is accepted or refused according to relevant configuration information (for example authentication information of operation layers such as Ye Wu account number, password).
At last, in call phase (being the session mounting phase), the application terminal is initiated to the conversation request of pstn telephone, and the destination of this signaling is BAC.This conversation request is delivered to BAC via BRAS, and BAC is transmitted to SS with it, by SS control SGW (SG) and Trunk Media Gateway (TG), sets up medium with the PSTN side and is connected.Under the situation of IAD phone and pstn telephone intercommunication, the medium transit point is BAC and TG.
This shows that in the prior art, the IP layer inserts not to be had related with operation layer registration, calling procedure.As long as network-in-dialing, service terminal just can carry out professional registration and calling procedure.This has limited the binding of carrying out some business games neatly at network insertion.In addition, prior art lacks the identification of service terminal and authentication, has also limited the binding of carrying out some business games neatly at custom terminal.
For this reason, the present invention proposes the method for the identification of a kind of VOIP service terminal and professional control, so that make things convenient for operator's strategy binding of commencing business neatly.According to the present invention, in the process of terminal carrying out service registration, carry out two additional judgements by BAC, promptly insert IP identification and terminal recognition, thereby realize using the judgement of terminal accessing-point, access carrier and terminal customized information.
According to the present invention, BAC receives the service log-on request that the application terminal sent, and reads the IP information that inserts from this service log-on request.For example, can determine to insert IP information by one of following information:
Entrained source IP in the IP header of a service log-on request message, this is applicable to the various situations of broadband access;
" Call-Id " territory in the b log-on message, this is applicable to that the value of Call-Id entrained in the service log-on request message can embody the situation of access-in point information, for example passes through under the situation of bridge connected home gateway broadband access in the application terminal.
Can select above two decision conditions according to the broadband access method of using.
If the IP that is read belongs to the VoIP particular ip address pond of the A of operator, then BAC can distinguish the control strategy of operator.Advantageously, BAC can also notify charging system to carry out the corresponding business rate via SS.Also can judge the region that the application terminal is inserted according to source IP, thus can corresponding binding this locality or service tariff of roaming and control strategy etc.
On the other hand, carried terminal information in log-on message comprises and utilizes the territory or the newly-increased territory that have now in the Session Initiation Protocol to come carried terminal information.According to one embodiment of present invention, preferably use " user-agent " territory carried terminal information of Session Initiation Protocol.For example, utilize " user-agent " territory in the log-on message, make the value of " user-agent " comprise the attribute such as operator, software and hardware version information etc. of terminal.BAC reads end message entrained in the log-on message, thereby carries out corresponding control strategy according to this information.Advantageously, BAC also carries out the corresponding business rate via SS notice charging system.
For IP identification and terminal recognition, can take ciphering process, true and reliable to guarantee relevant authentication information entrained in the service log-on message.An example of the process after the encryption (increasing the challenge/response verification process) is as follows:
1) in the service log-on stage, before sending service log-on information, the application terminal at first sends the terminal authentication request to BAC.The form of authentication request message can redefine, and also can use SIP service log-on message.Information and the present invention entrained in the authentication request are irrelevant;
2) BAC returns random code to the application terminal;
3) this random code is extracted in the application terminal, and the cryptographic algorithm by sharing with BAC, and the value of " user-agent " that will carry in random code and the service log-on message is encrypted; Send the SIP register requirement to BAC then.(encrypted result is carried in " call-Id " and " user-agent " territory in the SIP register requirement protocol package);
4) BAC utilizes identical random code, the original value of user-agent is encrypted, and the value of " user-agent " that carry in result and the service log-on message is compared.According to comparative result, carry out the triggering of related service strategy and control strategy.
Below introduce the method according to this invention in detail by two specific embodiments.
At first the SIP phone with the CT of China Telecom customization is flow process and the purpose that example is introduced the method according to this invention through the VOIP business that the bridge connected home gateway inserts China Telecom.In this example, the strategy that realize is: use the wide band access user of China Telecom can use the user of the VOIP business of China Telecom or the VOIP terminal that use China Telecom customizes can use the VOIP business of China Telecom.Broadband access process in the flow process is identical with process of the prior art, and the calling procedure after succeeding in registration or failing is also identical with process of the prior art, therefore omits the explanation for them.Below only introduce the service log-on process of the method according to this invention with reference to figure 3.
In this embodiment of the present invention, user's IP address is carried in " call-Id " territory of Session Initiation Protocol, " user-agent " territory carried terminal information, for example: ' user-agent:Chinatelecom-voip-software version-beta1.0 '.In the service log-on process, BAC reads the value of " Call-Id " in the log-on message, and the IP address pool of itself and CT is compared.If caller IP address belongs to the IP address pool of CT, then log-on message is forwarded to SS, continue VOIP service log-on process.Otherwise,, then can use the VOIP business of China Telecom or increase other strategies if the value init string of user-agent is " Chiantelecom "; If for not, then cannot use, perhaps limit other strategies.
Below use the VOIP terminal of China Telecom to carry out the VOIP business is introduced the method according to this invention as example flow process and purpose with the wide band access user use route formula home gateway online of Netcom again.Here the strategy of being taked is: the VOIP business of the China Telecom that the VOIP terminal of using China Telecom to customize inserts gives the preferential of rate 9.5 foldings with respect to the user of non-VOIP terminal, use the VOIP service-user of the China Telecom of China Telecom's broadband access to give preferential with rate 9.8 foldings with respect to the user of non-China Telecom broadband access, use the VOIP service-user of the China Telecom of China Telecom's broadband access can obtain free differentiated service guarantee in 10 hours, the combination in any of perhaps above-mentioned three kinds of strategies.Broadband access process in the flow process is identical with process of the prior art, and the calling procedure after succeeding in registration or failing is also identical with process of the prior art, therefore omits the explanation for them.Below only introduce the service log-on process of the method according to this invention with reference to figure 3.
In this embodiment of the present invention, Session Initiation Protocol " user-agent " territory carried terminal information, for example: ' user-agent:Chinatelecom-voip-software version-beta1.0 '.BAC reads source IP entrained in the IP message of service log-on request message, and the IP address pool of itself and CT is compared, and is found to be China Telecom's wide band access user; So continue to read the value of user-agent, init string is " Chiantelecom ", judge that then the VOIP that can use China Telecom is professional and can obtain preferential (the VOIP business of the China Telecom that the VOIP terminal of promptly using China Telecom to customize inserts gives the preferential of rate 9.5 foldings with respect to the user of non-VOIP terminal) that rate 9.5 are rolled over, transmit this information and open this charging policy to the corresponding business charge system via SS simultaneously.
The advantage of the method according to this invention is, can be at the base that does not change the existing protocol process On the plinth, solve easily the deficiency of existing scheme, thereby can open for network insertion neatly Open up the binding of some business games. The method according to this invention has solved business side to service terminal Identification and authentication, be convenient to carry out for custom terminal neatly the binding of some business games.
