Description
Technical field
The present invention relates to the communications field, particularly the session charging technology.
Background technology
PoC claims Push to talk over Cellular again, and it has introduced the voice communication service of direct point-to-point and point-to-multipoint in cellular network.It makes the user can utilize mobile phone to enjoy popular double-direction radio intercommunication business, and promotes mobile service thus.PoC service can improve the network utilization of mobile operator, increases considerably the data service throughput, thereby excavates the new market opportunity for mobile operator and service provider.
Simply introduce the principle of PoC below: the user only needs one to press, and can begin conversation.Connect by " online all the time ",, just can start individual and group call as long as the user presses a key on the phone.Calling out connection almost is to connect at once, and those who answer does not need specially to answer.The user of voice PTT business can handle other things usually when incoming call is arranged, they can listen to group call at hand when continuation is worked.Certain user can connect by name, and he can deliver some suggestions to phone group once in a while.The most suitable this use occasion of half-duplex call.
In addition, the user can also form phone group on the basis of " ad hoc ", and needn't connect service provider separately, like this can for spontaneous and flexibly group call facilitate.This simple and direct direct communication can be satisfied business users and personal user's multiple needs---from controlled Team Management, experiences and enjoyment to spontaneously sharing.Voice PTT business is a kind of real differential speech business, because it is not substituting of existing any one cellular services.It makes operator have an opportunity to develop own brand-new speech business, and needn't change traditional voice service.
Generally speaking, PoC has the characteristic of a cover packet voice (Voice overIP is called for short " VoIP ") Communications service and instant note style, as presence prompting and message etc.The user can obtain such as voice services such as man-to-man dialogue, special grouping, grouping dialogue and chat groups, and its system configuration as shown in Figure 1.
In PoC, the correlation of communication entity is as shown in Figure 2: control PoC function (ControllingPoC Function, be called for short " CPF ") be communication core, carry out centralized control, carry out and to comprise functions such as session control (Control on Communication such as foundations/cancellation session, signaling and media negotiation, processing request, distribution media stream), group's strategy execution (comprise collection and control service quality) and user's face be adaptive.Corresponding one of each terminal adds PoC function (Participate PoC Function, be called for short " PPF "), each PPF session operation all is to send request to CPF, by CPF coordinate the control conversation procedure (as distribution of media, data pass on, authority and the role shifts, QoE authentication etc.).The communication between terminals that adds session is to CPF request and reception CPF instruction by PPF, CPF is according to strategy, to PPF distribution media, data, afterwards, each PPF is transmitted to the corresponding terminal that connects with it, finishes the communication of the point-to-point or point-to-multipoint between the terminal.CPF and PPF are functional module, and they may reside on 1 PoC server, also can adhere to separately on the different PoC servers, carry out difference in functionality.
At present, when PoC session is set up, there are 2 kinds of modes: set up as required (On-demanded) and pre-established (Pre-established).
The session of On-demanded type is set up flow process as shown in Figure 3, endpoint registration to the PoC server after, do not carry out the initialization negotiations process at once, but when the request of terminal initiation/reception PoC session (the 5th step among Fig. 1 .2.1.1), just begin to carry out the necessary process of session initialization of session such as service quality, medium, finish up to negotiation, PoC session request or media content could be initiated/be accepted to terminal, and terminal can begin during the session there is long stand-by period (being referred to as the QoE ' Right tospeak ' impression) from being registered to like this.
The session of Pre-established type is set up flow process as shown in Figure 4, endpoint registration is behind the PoC server, automatically begin to carry out service quality, the work that conversation initializations such as media negotiation are necessary, after this process is finished, terminal can be initiated/accept the PoC session request at any time and not need similarly to consult (comprising the negotiation once more of lower floor's carrying) process again, can save the response time that service was initiated/accepted request to terminal like this, avoid time-consuming operations such as media negotiation after this, such as initiating/when accepting medium, need not in the On-demanded type of session, essential IM CN subsystem (the IPMultimedia Subsystem that carries out earlier, abbreviation " IMS ") service quality of layer is identified (QoS Authentication) and a series of negotiation of authorization processes of lower floor thereof, reached the purpose that improves response speed, thereby the service quality that makes terminal experience is significantly improved.
Be not difficult to find, for the On-demanded type of session, only after initiating the PoC request, just can need to set up PoC session a series of initial work of (being connected between PoC terminal and the PoC server), and the Pre-established type of session, then after the IMS registration is finished, promptly begun conversation initialization work (difference is as the dash area among Fig. 3 and Fig. 4), therefore, for the terminal of setting up the Pre-established type of session, when it need initiate the PoC session request, owing to finished initialized a series of negotiations of PoC session and processing in advance, terminal can begin PoC conversation/medium conversations (talk/mediaburst) very soon, has reduced wait/response time, the terminal of On-demanded type of session then has a relatively long stand-by period, so response speed is lower.
For above process, no matter terminal is initiation PoC request or accepts request that process steps all is the same.In addition, session both sides' PoC terminal can adopt different conversation initialization modes, and promptly a side sets up the On-demanded type of session, and the opposing party then can adopt the Pre-established type of session.
This shows, for dissimilar process of session initialization, be to realize different service quality between PoC terminal and the PoC server with diverse ways, to this dissimilar service and user experience, need a kind of method of charging that it is distinguished, and in customer charge control, embody to some extent, so that embody the differentiated service of operator, but in present prior art, do not propose to embody the charging method of this opposite sex in poor service as yet.

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 accompanying drawing.
In embodiments of the present invention, because the service otherness is embodied in conversation initialization period, set up in case finish session, session character just can not remake variation, thus adopt billing model based on incident, and at the event charging during the conversation initialization.That is to say, server is when the conversation initialization request of receiving terminal, send the charging request of the conversation initialization type comprise this terminal to billing function equipment, billing function equipment is carried out corresponding charging policy according to the conversation initialization type of carrying in the request of chargeing.
Specifically, as shown in Figure 5, in step 510, after the PoC terminal is finished the IMS registration, just require to connect PoC server (PoC AS Connection).
In step 520, PoC server (i.e. PPF﹠amp among the figure; CPF) receive the session connection request that terminal initiates after, judge whether this terminal can initiate this conversation initialization request, if can, the PoC server is carried out the PoC session initialization procedure of the type, as the PoC session initialization procedure of Pre-established type or On-demanded type.
Then, in step 530, PoC server affirmation PoC terminal can be initiated certain type of session initialization request, and initiates corresponding charging request (Charging Request) to billing function equipment, comprises conversation initialization type relevant information in the request.
Then, in step 540, after billing function equipment is received the charging request that has conversation initialization type relevant information, carry out corresponding charging policy according to conversation initialization type relevant information.
Then, in step 550, billing function equipment charges to the feedback of PoC server and replys (ChargingResponse), and feedback is to the implementation status of the charging request of this PoC server proposition.After finishing these a series of operations, session continues, as step 560.
Below first execution mode of the present invention is elaborated, present embodiment relates to session billing method, in the present embodiment, the PoC terminal is carried the conversation initialization type in the conversation initialization request, the PoC server directly obtains the conversation initialization type from the conversation initialization request of PoC terminal, idiographic flow as shown in Figure 6.
In step 610, the PoC terminal sends the conversation initialization request to the PoC server, and carries the relevant information of conversation initialization type in this request.Such as, the PoC terminal is the conversation initialization request of Pre-established type to the initiation of PoC server, then this PoC terminal is after finishing the IMS registration, no matter currently whether to begin session, all send the conversation initialization request to the PoC server immediately, and the conversation initialization type of carrying is the Pre-established type in this request.If the PoC terminal is the conversation initialization request of On-demanded type to the initiation of PoC server, then this PoC terminal is after finishing the IMS registration, user in this terminal presses the button, when request is initiated/is accepted session in expression, this PoC terminal sends the conversation initialization request to the PoC server again, and the conversation initialization type of carrying in this request is the On-demanded type.
Then, enter step 620, the PoC server is initiated the request of chargeing to billing function equipment, carries the conversation initialization type in this charging request.Specifically, the PoC server is after the conversation initialization request that receives the PoC terminal, judge whether this terminal has the right to initiate this conversation initialization request, if this terminal can be initiated this conversation initialization request, then this PoC server is initiated the request of chargeing according to the conversation initialization type in the conversation initialization request of receiving to billing function equipment.
Such as a field of expansion (as PoC session initiationtype) is used to represent conversation initialization type identification number in existing charging request, and its value can be divided into: " 1 " expression the type is the Pre-established type; " 2 ", expression the type is the On-demanded type, and is as shown in table 1.

Table 1
This shows,, the session initialization type is carried in the request of charging, make that present embodiment can be compatible better with prior art by at the request extended field that charges.
In addition, need to prove, can also carry other information relevant in the charging request with this session, such as, the effective duration of type (as Expire), type upgrade the required time interval (as Validate Interval), finish the time related information of conversation initialization (as TimeStamp, TimeZone) and the initialization times relevant information (as Max number/number ofinitiation) etc. of finishing the session type.Can also carry other information relevant if charge in the request with this session, Kuo Zhan " PoC session initiation type " can be the structure of a group (Grouped) type so, so that carry conversation initialization type and other relevant information therein.
Then, enter step 630, billing function equipment is carried out corresponding charging policy according to the relevant information in the request of chargeing.Specifically, because the PoC terminal selects to use dissimilar conversation initialization modes, can reach the PoC service of enjoying different quality, therefore, billing function equipment need be according to the conversation initialization type information in the request of chargeing, it is corresponding with it to determine carry out which class charging policy, makes the calculating of telephone expenses can embody the otherness of service quality.That is to say that with the corresponding different rates of different conversation initialization types, when the PoC terminal was carried out initialization, initialization type can be used as one of rates ground (dissimilar sessions, corresponding different rates), charges in the charging data record.
In addition, number of times and/or time that the conversation initialization of certain type is carried out also can be used as one of rates ground, charge in the charging data record.Such as, with certain type of session initialization times of carrying out, as one of charging quantity (Charging amount); To with the initialized session of Pre-established type, be accomplished to the period that begins between the talk/media burst from the PoC session initialization, can carry out one different with the talk/media burst period, the rate of this section asynchronism(-nization) before also initiating a session request with On-demanded.
To the above data of charging to charging data record, can also in BILLING (account system), determine to carry out which type of charging policy.This shows, number of times and/or time that billing function equipment is carried out according to the conversation initialization of the conversation initialization type of carrying in the charging request of receiving and the type, carry out corresponding charging policy, can make the calculating of telephone expenses further embody the otherness of service quality.
In addition, what deserves to be mentioned is that billing function equipment can also be carried out corresponding charging policy in conjunction with current sessions initialization type and other session control information.Such as, to finishing conversation initialization, but follow-uply carry out the session of time talk/media burst arbitrarily, can not carry out in due order/charging of period/type, and only it is carried out one-off charge (promptly only to this initialization event record once, have later on again, merge in first record); Perhaps, some feature in the record PoC terminal initial conversation procedure such as continuously initiating initialization request etc., records in the charging data record, and by charge system or the comprehensive decision problem concrete condition of backstage account system, whether decision is to its charging.
Second execution mode of the present invention relates to session billing method, the present embodiment and first execution mode are roughly the same, its difference is, in the first embodiment, the PoC terminal is carried the conversation initialization type in the conversation initialization request, the PoC server directly obtains the conversation initialization type from the conversation initialization request of PoC terminal.And in the present embodiment, in the conversation initialization request of PoC server according to the PoC terminal, whether comprise the initialization desired parameters, judge that this conversation initialization type is the On-demanded type, or the Pre-established type.That is to say, during PoC terminal initiation session initialization request, can not carry conversation initialization type relevant information, the PoC server is distinguished different between this conversation initialization request and other PoC session request, determines the type of this conversation initialization.
Specifically, be the session billing method of Pre-established type for the conversation initialization type, as shown in Figure 7.In step 701, after the PoC terminal is finished the IMS registration, just require to connect PoC server (PoC AS Connection).
Then, in step 702a, the PoC terminal is to PoC server (i.e. PPF ﹠amp among the figure; CPF) send the INVITE request message, after the INVITE request message is used for the PoC terminal and the PoC server is connected, it is used to carry out the processing of Media/QoS parameter negotiations such as (medium/service quality), the INVITE difference that other common conversation request of its information that comprises is used.
Therefore, in step 702b, do not comprise information such as calling party address in the INVITE request message that the PoC server is received, but contain SDP (Session Description Protocol), QoS (service quality), a series of initialization desired parameters such as RTP (RTP) port numbers.The PoC server can be crossed the difference of difference INVITE request, judges the PoC terminal and belongs to the Pre-established type connecting the initialization operation of being done behind the PoC server.
Then, the PoC server returns 200 OK response messages to the PoC terminal, and sends the charging request that comprises the conversation initialization type to billing function equipment, as step 702c and step 703.
Because the conversation initialization type is the session of Pre-established type, the PoC terminal has promptly been initiated the conversation initialization request to the PoC server after finishing the IMS registration, therefore, when the user of PoC terminal presses the button beginning Talk/media burst, what this PoC terminal was sent is the REFER request, and do not resemble the On-demanded type of session when pressing the button, initiation be a conversation initialization request.Therefore, after the user of PoC terminal presses the button beginning Talk/media burst, this PoC terminal has been initiated call request/set up Media Stream to the PoC server, billing function equipment is according to the conversation initialization type in the charging request of receiving before, carry out corresponding charging policy, to embody the otherness of service quality, as step 704 and 705.
Then, in step 706, billing function equipment charges to the feedback of PoC server and replys.
Then, in step 707, the PoC server sends the conversation acknowledge message to the PoC terminal, and afterwards, session continues, and as step 708 and 709, this PoC terminal sends Media Stream to the PoC server, and the PoC server sends this Media Stream to the other end of session.
For the conversation initialization type is the session billing method of On-demanded type, as shown in Figure 8.In step 801, after the PoC terminal is finished the IMS registration, just require to connect PoC server (PoCAS Connection).
Then, after the user of PoC terminal pressed the button beginning Talk/media burst, this PoC terminal was to PoC server (i.e. PPF﹠amp among the figure; CPF) initiation session initialization request (INVITE) is as step 802a.It is such to be different from the Pre-established type of session, the PoC server can just be received the conversation initialization request of this PoC terminal before the user presses the button, in the On-demanded type of session, only the user in terminal presses the button, after Talk/Media Burst is initiated/accepts in expression, the PoC server just can be received the INVITE request, and this INVITE request is a common conversation request (Normal PoC SIP INVITE).
Then, in step 802b and 802c, this PoC terminal needs and the PoC server is finished Media/QoS a series of negotiations such as (medium/service quality), just calculates then and finishes process of session initialization.
Because the PoC terminal is a common conversation request to the transmission of PoC server, therefore, this PoC server can judge in view of the above that the conversation initialization type that this PoC terminal is initiated is the On-demanded type, therefore, step 803 to 805 in, the PoC server sends to billing function equipment and comprises the charging request that the conversation initialization type is the On-demanded type, billing function equipment is according to the conversation initialization type in the charging request of receiving, carry out corresponding charging policy, and reply to this PoC server feedback charging.
Step 806 is identical to step 709 with step 707 respectively to step 808, does not repeat them here.
