Detailed Description
The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, and not all of the embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the disclosure, its application, or uses. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.
The inventor researches and discovers that in an online charging process of a prepaid service, when a calling party starts a call by using a video, if a called terminal does not support a video call or the called party is connected by using an audio, an Application Server (AS) in the related technology reports the OCS according to the highest media type (video) in a call message. Since the AS reports the media type (video) of the SDP (Session Description Protocol) initiator, which is not consistent with the media type (audio) of the actual call, an OCS charging error may be caused, causing a user complaint.
In view of the above problems, the present disclosure provides a message sending method, which can perform charging according to the media type of the actual call, improve the accuracy of OCS charging, and reduce user complaints. As described in detail below.
Some embodiments of the disclosed messaging method are first described in conjunction with fig. 1.
Fig. 1 illustrates a flow diagram of a method of messaging in accordance with some embodiments of the present disclosure. As shown in fig. 1, the present embodiment includes steps S102 to S104.
In step S102, the application server obtains the media type of the session description protocol responder from the received session initiation protocol SIP message.
For the negotiation of media types, this can be implemented in the interaction of SDP messages. The party that first sends the SDP message is called an SDP initiator (offer), and the party that receives the SDP message to reply and replies to the SDP message is called an SDP responder (answer). The SDP initiator may provide a plurality of media types for selection by the SDP responder, which may select only one of them, the actual session media type being determined by the SDP responder. It will be understood by those skilled in the art that the SDP message may be included in a SIP (Session Initiation Protocol) message, so that negotiation of the media type between the SDP initiator and SDP responder may be implemented through SIP message interaction based on a SIP Protocol three-way handshake mechanism.
When the SDP initiator and SDP responder perform SIP message interaction, each SIP message sent to each other needs to pass through the application server. The application server can judge whether the received SIP message contains SDP message, if not, the application server does not process, if yes, the application server obtains the media type of the session description protocol responder from the SDP message contained in the received SIP message, and the SDP message is contained in the SIP message as an optional message.
It should be understood that due to the existence of the playing platform such as the color ring, the SDP initiator is not necessarily the calling party of the call, and the SDP responder is not necessarily the called party of the call. For example, a calling party initiates an audio call to a called party, but a called polyphonic ringtone service platform enforces to play a multimedia polyphonic ringtone to the calling party, i.e. the call service type is switched from the audio call to the video call. At this time, because the polyphonic ringtone platform in the network initiates the media type switching, the SDP initiator is called, and the SDP responder is calling.
The application server can also obtain the identity information of the initiator of the session description protocol, the identity information of the responder of the session description protocol, the forward network information and the backward network information from the SDP message contained in the received SIP message. The application server may then construct an OCP message based on the media type, the sip initiator identity information, the sip responder identity information, the forward network information, and the backward network information. Wherein, the network element which triggers the service and sends the Invite message to the service belongs to the forward network; and the network element which sends the Invite message to the IMS after the prepayment AS executes the service logic belongs to the backward network.
In step S104, the application server sends an online charging protocol OCP message to the online charging system OCS, where the OCP message carries the media type.
After receiving the OCP (Online Charging Protocol) message, the OCS may perform corresponding Charging processing according to the media type carried in the OCP message. Different call service types comprise video call, high-definition voice call and standard-definition voice call, and the corresponding media types are video and audio respectively, wherein the audio is divided into AMR (adaptive rate modulation) and G.711 coding. The OCS needs to identify the call service type according to the media type, so as to differently deduct the charges for different call service types according to different charge rates.
In the above embodiment, the prepaid AS carries the media type of the session description protocol responder when reporting the prepaid online charging message, and the media type is the result of SDP negotiation between the SDP initiator and the responder, thereby implementing charging according to the media type of the actual call, improving the accuracy of OCS charging, and reducing user complaints.
There are four possible SDP negotiation modes before the called terminal in the prepaid call flow goes off-hook to answer. The first SDP negotiation mode is that the calling party initiates SDP negotiation to the called party through Invite message, and the called party replies 180Ringing message for SDP response. The second SDP negotiation mode is that the calling party is not the SDP initiator, but the called party initiates SDP negotiation to the calling party through 180Ringing message, and the calling party replies SDP response through replying PRACK message. The third SDP negotiation manner is that the calling party initiates SDP negotiation to the called party by sending an Invite message, and the called party replies with a 200OK message to perform SDP answer. The fourth SDP negotiation manner is that the calling party is not the initiator of SDP negotiation, the called party initiates SDP negotiation by sending a 200OK message first, and the calling party performs SDP answer by replying an ACK message.
Thus, in some embodiments, the session initiation protocol, SIP, message comprises: a 180Ringing message in response to the Invite message, a 200OK message in response to the Invite message, a PRACK message in response to the 180Ringing message, and an ACK message in response to the 200OK message sent by the session description protocol responder. Correspondingly, in step S104 of the embodiment shown in fig. 1, the application server sends the initialized credit control request CCR to the OCS, so that the OCS performs resource reservation according to the media type carried by the initialized CCR. The resource reservation can be understood as calculating the available longest call duration according to the balance and the current service rate.
In the embodiment, the prepaid AS reports the SDP negotiation result to the OCS according to the media type of the SDP responder in the prepaid calling process, so that online charging is realized according to the media type of the actual call, the charging accuracy of the OCS is improved, and the user complaints are reduced.
Before the called party answers the call, the calling party and the called party can carry out SDP negotiation again through Update messages. In this SDP negotiation manner, the SDP initiator may initiate SDP negotiation by sending an Update message before the called call answers, and the SDP responder may answer the SDP by replying to a 200OK message. Thus, in some embodiments, the session initiation protocol, SIP, message comprises a 200OK message sent by the session description protocol responder in response to the Update message. Accordingly, in step S104 of the embodiment shown in fig. 1, the application server sends the updated CCR to the OCS, so that the OCS performs the charge reservation and re-pricing according to the media type carried by the updated CCR.
For example, because the charges of the video call and the audio call are different, when the media type switching occurs, it means that the call service type is switched, and at this time, the OCS calculates the occurred charge according to the charge rate before the media type switching and the usage time before the media type switching, and subtracts the occurred charge from the balance to obtain the latest balance, that is, the charge reservation. Meanwhile, the OCS calculates the longest duration of the call after the media type is switched, that is, the rating is charged again, according to the rate after the media type is switched. The OCS may notify the prepaid AS of the calculation result, so AS to monitor the call and prevent the call from being overtime.
In the embodiment, the prepaid AS reports the SDP negotiation result to the OCS according to the media type of the SDP responder before the call, so that online charging is realized according to the switched media type, the charging accuracy of the OCS is improved, and the user complaints are reduced.
During the call, both the caller and the callee may send an Invite message again (distinguished here by an Invite message before the call answer, referred to herein as a re Invite message) to re-perform SDP negotiation. The SDP negotiation mode is that an SDP initiator initiates SDP negotiation to a called party by sending a Reinvite message, and an SDP responder carries out SDP response by replying a 200OK message. Thus, in some embodiments, the session initiation protocol, SIP, message comprises a 200OK message sent by the session description protocol, SIP, responder in response to the ReInvite message. Accordingly, in step S104 of the embodiment shown in fig. 1, the application server sends the updated CCR to the OCS, so that the OCS performs the charge reservation and re-pricing according to the media type carried by the updated CCR.
In the above embodiment, the prepaid AS reports the SDP negotiation result to the OCS according to the media type of the SDP responder during the call, so that online charging according to the switched media type is realized, the accuracy of charging by the OCS is improved, and user complaints are reduced.
A specific application example of the message sending method of the present disclosure is listed below for further explanation.
