Abstract
The invention discloses an offline charging control method and a system, applied to the precise charging for the transportation of the session initiation protocol message. The method in the invention includes that the sender transmits the session initiation protocol message; the push-to-talk server receives the message and forwards to the receiver; whether the feedback message from the receiver is successfully received by the push-to-talk server or not is determined, if yes, the charging request unit of the push-to-talk server begins charging. The invention also provides a system for realizing the method. The invention can effectively enhance accuracy and flexibility of charging.
Description
Technical field
The present invention relates to the communications field, relate in particular to a kind of offline billing control method and system.
Background technology
Putting call through immediately after connection (PoC, Push to Talk over Cellular) business is a kind of internet protocol-based (IP, Internet Protocol) the cluster media communication business of technology, it utilizes bearer network, realize with half-duplex internet voice service (VoIP, Voice over Internet Protocol) technology.PoC user can carry out half-duplex call point-to-point, point-to-multipoint with other PoC users after configuring group's list.
As shown in Figure 1, a kind of offline billing control method is in the prior art:
X1) sending direction PoC server sends Session initiation Protocol (SIP, Session InitiationProtocol) message;
X2) after the PoC server received message, the request Charging Detail Record unit chargeed;
X3) Charging Detail Record unit charges;
X4) charge finish after to PoC server feedback charging result.
But, because the transmittance process of sip message from the PoC server to the recipient not necessarily can be successful, just do not meet the charging principle so receiving at the PoC server charges behind the sip message of transmit leg, may charge yet, cause user's loss the message of bust this.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of offline billing control method and system, is used for accurately transmission of messages being chargeed.
Offline billing control method provided by the invention is applied to instant personal messages service, comprises step: charging policy is set; Transmit leg sends conversation launch protocol message; The putting call through immediately after connection server receives described message and forwards it to the recipient; The putting call through immediately after connection server judges whether the feedback message that receives from the recipient is successful, if success, then putting call through immediately after connection server requests Charging Detail Record unit charges; If it is unsuccessful that the recipient receives conversation launch protocol message, then described conversation launch protocol message not to be chargeed or charges be 0 to Charging Detail Record unit, and revise charging policy according to charging case.
Preferably, whether the described feedback of judging that the putting call through immediately after connection server receives from the recipient successfully comprises step: whether receive recipient's feedback message after judging putting call through immediately after connection server forwards conversation launch protocol message, if receive, then judge and receive successfully, if do not receive, judge then whether retransmit number of times transfinites,, then judge to take defeat if transfinite.
Preferably, whether the described feedback of judging that the putting call through immediately after connection server receives from the recipient successfully comprises step: whether receive recipient's feedback message after judging putting call through immediately after connection server forwards conversation launch protocol message, if receive, then judge and receive successfully, if do not receive, then judge whether to surpass the thresholding stand-by period,, then judge to take defeat if surpass.
Preferably, described recipient's feedback message comprises that the recipient receives whether success, the reason that takes defeat, bang path, time-delay of conversation launch protocol message, whether retransmits, retransmits number of times and retransmit shared resource.
Preferably, after chargeing, putting call through immediately after connection server requests Charging Detail Record unit further comprises step: if the recipient receives the unsuccessful then recorder failure cause of conversation launch protocol message, if the recipient receives the conversation launch protocol message success, then charge according to described charging policy.
Preferably, described putting call through immediately after connection server comprises participant putting call through immediately after connection server, control putting call through immediately after connection server and the side's of adding putting call through immediately after connection server; Described forwarding comprises step: control putting call through immediately after connection server notification participant putting call through immediately after connection server sends to adding side's putting call through immediately after connection server with the session initialization protocol message; The side's of adding putting call through immediately after connection server sends to the recipient with described message.
Preferably, further comprise step after receiving recipient's feedback message: the putting call through immediately after connection server is transmitted to transmit leg with described recipient's feedback message.
Offline charging control system provided by the invention is applied to instant personal messages service, comprising: transmit leg, recipient, putting call through immediately after connection server, Charging Detail Record unit; Described transmit leg is used to send conversation launch protocol message; Described putting call through immediately after connection server receives the conversation launch protocol message of transmit leg transmission and transmits described conversation launch protocol message to the recipient; Described recipient is used to receive the conversation launch protocol message from the putting call through immediately after connection server forwards, and sends feedback message; The request Charging Detail Record unit chargeed after described putting call through immediately after connection server received recipient's feedback message; If it is unsuccessful that the recipient receives conversation launch protocol message, then described conversation launch protocol message not to be chargeed or charges be 0 to Charging Detail Record unit, and revise charging policy according to charging case.
Preferably, described putting call through immediately after connection server comprises participant putting call through immediately after connection server, adding side's putting call through immediately after connection server and control putting call through immediately after connection server;
Described participant putting call through immediately after connection server is used to receive the message that transmit leg sends, and described message is sent to adding side's putting call through immediately after connection server according to the notice of control putting call through immediately after connection server, after the side's of adding putting call through immediately after connection server is received message, give the recipient with described forwards.
Above technical scheme as can be seen, the present invention has the following advantages:
1), the message of bust this and the message of transmission success are carried out the charging policy of distinguishing property, so it is more accurate to charge owing to PoC server among the present invention will ask Charging Detail Record unit that message is chargeed after receiving recipient's feedback message;
2) because the present invention has considered the situation of multiple bust this or error of transmission, and provided corresponding processing mode, perfect charging flow is so the present invention has improved reliability of system operation;
3) owing to the present invention proposes charging policy, and charging policy is adjusted, so improved the flexibility of chargeing according to the message transmission situation.
