Detailed Description
Before the technical solution of the embodiment of the present invention is introduced, a description is given of a related art.
In the related art, with the rapid release of mobile terminal technology and internet technology, a calling terminal may initiate a voice call to a called terminal. In practical application, when a calling terminal wants to transmit important information to a called terminal, the calling terminal can set the initiated voice call as an important call and transmit the set important call to the called terminal so as to establish the important call with the called terminal. In the related art, the problem of high signaling overhead exists when the calling terminal initiates an important call.
Based on this, in various embodiments of the present invention, a calling terminal sends an SIP message to a called terminal; the SIP message is used for indicating to initiate an important call based on a specific voice service to the called terminal; the calling terminal receives a response message aiming at the SIP message sent by the called terminal; the calling terminal sends SIP INVITE a call request to the called terminal; the SIP INVITE call request is for requesting that the important call be established.
The present invention will be described in further detail with reference to the accompanying drawings and examples.
An embodiment of the present invention provides a call establishment method, as shown in fig. 1, the method includes:
step 101: a calling terminal sends an SIP message to a called terminal; receiving a response message aiming at the SIP message sent by the called terminal; the SIP message is used for indicating to initiate an important call based on a specific voice service to the called terminal;
step 102: the calling terminal sends SIP INVITE a call request to the called terminal; the SIP INVITE call request is for requesting that the important call be established.
Here, in step 101, the specific Voice service may refer to a Voice over Long-Term Evolution (VoLTE) service based on an IP multimedia subsystem, such as a high definition digital Voice service and a high definition digital video service that require a high transmission rate, or may refer to a Voice service in a future fifth generation mobile communication system. Taking the VoLTE service as an example, after the called terminal triggers the VoLTE service, the calling terminal can transmit the initiated important call to the called terminal through the SIP message, and the signaling interaction between the calling terminal and the called terminal is less, so that the signaling overhead can be saved.
Here, in step 102, when the calling terminal triggers the specific voice service, the calling terminal may send SIP INVITE call signaling to the called terminal to establish an important call using the SIP protocol.
In practical application, when the calling terminal initiates an important call to the called terminal, the calling terminal can set a caller identification and a caller ringtone when the called terminal receives a call, so as to prompt the importance of the current call of the called terminal.
Based on this, in an embodiment, the method further comprises:
the calling terminal acquires a URL of a first multimedia file corresponding to the mark of the important call and a URL of a second multimedia file corresponding to the ringing ringtone of the important call;
the calling terminal generates an SIP message based on the URL of the first multimedia file and the URL of the second multimedia file; and the URL of the first multimedia file and the URL of the second multimedia file are used for displaying the mark of the important call by the called terminal and playing a ringing ring corresponding to the important call.
Here, the mark of the important call may refer to a caller id set by the calling terminal; the ringing ringtone corresponding to the important call may be an incoming ringtone set by the calling terminal. The first multimedia file corresponding to the mark of the important call can be specifically a picture and the like; the second multimedia problem corresponding to the ringing ringtone corresponding to the important call may specifically be audio and the like.
In practical application, after the calling terminal orders the important call service, the important call can be initiated to the called terminal, so that the calling terminal can order the important call service on a service management platform and obtain the URLs of the first multimedia file and the second multimedia file from the service management platform.
Based on this, in an embodiment, the obtaining, by the calling terminal, the URL of the first multimedia file corresponding to the tag of the important call and the URL of the second multimedia file corresponding to the ringing tone of the important call includes:
the calling terminal sends an order request to a service management platform; the ordering request is used for requesting to open an important conversation service;
the calling terminal receives a response message aiming at the order request sent by the service management platform; the response message is used for indicating that the calling terminal is allowed to open an important call service;
and the calling terminal executes setting operation aiming at the important call mark and the ringing ringtone so as to receive the URL of the first multimedia file and the URL of the second multimedia file returned by the service management platform.
Here, a user using the calling terminal may access the service management platform on the calling terminal, and after the service management platform opens and orders the important call service, the service management platform may browse and set personalized important call information on the service management platform, for example, open the important call service, select an important call service package, select a style of a tag of the important call, select a ringing tone of the important call, and the like, and after the user has set the important call information, the service management platform may return, to the calling terminal, a URL of a first multimedia file corresponding to the tag of the important call and a URL of a second multimedia file corresponding to the ringing tone of the important call. The important call service package can be set according to the operation requirement, for example, monthly or daily several points-several points/times.
In practical application, because the calling terminal sends the called terminal the URL of the first multimedia file corresponding to the mark of the important call and the URL of the second multimedia file corresponding to the ringing ringtone of the important call, in order to avoid that the call signaling of the calling terminal is sent to the called terminal but the called terminal cannot display the incoming call display and the incoming ringtone of the important call of the calling terminal device in time, after the called terminal can receive the SIP message sent by the calling terminal, the called terminal can send a response message aiming at the SIP message to the calling terminal after downloading the first multimedia file corresponding to the mark of the important call and the second multimedia file corresponding to the ringing ringtone of the important call, so that the called terminal can be ensured to display the incoming call display and the incoming ringtone set by the calling terminal in time when receiving the incoming call of the calling terminal.
Based on this, in an embodiment, the receiving, by the calling terminal, a response message to the SIP message sent by the called terminal includes:
and after the called terminal downloads the first multimedia file and the second multimedia file according to the URL of the first multimedia file and the URL corresponding to the second multimedia file, the calling terminal receives a response message aiming at the SIP message, which is sent by the called terminal.
In practical application, a calling terminal can send an SIP message to a called terminal through an AS, after the SIP message is received by the AS, if the SIP message carries a URL of a first multimedia file corresponding to a mark of an important call and a URL of a second multimedia file corresponding to a ringing ringtone of the important call, a service management platform can be requested to check whether the calling terminal subscribes the important call service or not, and whether the URL of the first multimedia file and the URL of the second multimedia file are accurate or not, so that the quality of the important call initiated by the calling terminal is ensured.
Based on this, in an embodiment, the sending, by the calling terminal, the SIP message to the called terminal includes:
the calling terminal sends SIP information to AS;
and sending the SIP message to the called terminal through the AS.
The calling terminal sends an SIP message to the AS, and the AS analyzes the SIP message after receiving the SIP message to obtain key content carried by the SIP message; and initiates a service auditing request to the service management platform through a HyperText Transfer Protocol (HTTP) GET message. And after receiving the service auditing request sent by the AS, the service management platform audits whether the calling terminal subscribes the important call service, whether the URL of the first multimedia file, the URL of the second multimedia file are accurate and the like, and returns an auditing response message to the AS. If the URL of the first multimedia file and the URL of the second multimedia file are checked to be not wrong, the service management platform returns a response message of successful checking to the AS, and the AS forwards the SIP message sent by the calling terminal to the called terminal; if the URL of the first multimedia file and the URL of the second multimedia file are checked to be wrong, the service management platform returns a correct URL to the AS, the AS carries the correct URL in an SIP Message sent by the calling terminal and forwards the SIP Message to the called terminal, and the AS can also feed back an SIP Message 4XX Message to the calling terminal to prompt the calling terminal to reorder the mark of the important call and the ringing corresponding to the important call.
In an example, as shown in fig. 2, a process of a calling terminal initiating an important call to a called terminal is described, which includes:
step 201: the calling terminal generates an SIP message.
Here, before step 201, when the calling terminal triggers the VoLTE service, the URL of the first multimedia file corresponding to the tag of the important call and the URL of the second multimedia file corresponding to the ringing tone of the important call may be obtained; and using the URL of the first multimedia file as a first field, using the URL of the second multimedia file as a second field, using the important call label as a third field, and generating an SIP Message, namely the SIP Message, from the first field, the second field and the third field.
And the positions of the first field, the second field and the third field in the SIP message are not limited. When the value of the third field is 0, representing that the current call is a common call; and when the value of the third field is 1, representing that the current call is an important call.
Step 202: and the calling terminal sends the SIP message to the called terminal and receives a response message aiming at the SIP message sent by the called terminal.
Here, as shown in fig. 3, the process in which the calling terminal sends the SIP message to the called terminal and receives the response message for the SIP message sent by the called terminal includes:
step 1: a calling terminal sends an SIP message to a called terminal;
here, a VoLTE call module in the calling terminal sends a notification message to a message module; the notification message is used for indicating the message module to send the SIP message to the called terminal.
Besides the conventional SIP message fields, such as a From header field, a to header field, and a Feature Tag ICSI Tag of an Important call, the SIP message may also carry an Important call field, an Important id field, a Media URL field, and the like in the xml message body of the SIP message. The Important call field corresponds to the third field, and the Media URL field corresponds to the first field and the second field.
Here, the SIP message may specifically be:
step 2: and the called terminal downloads the first multimedia file and the second multimedia file carried by the SIP message.
And step 3: and the called terminal downloads the first multimedia file and the second multimedia file and then sends a response message aiming at the SIP message to the calling terminal.
Here, as shown in fig. 4, the process of the calling terminal sending the SIP message to the called terminal includes:
step 1: the calling terminal sends SIP information to AS;
step 2: and the AS initiates a service auditing request to the service management platform.
And step 3: and the service management platform returns an audit response message to the AS.
And if the URL of the first multimedia file and the URL of the second multimedia file are not checked to be wrong, the service management platform returns a response message of successful checking to the AS. And if the URL of the first multimedia file and the URL of the second multimedia file are checked to be wrong, the service management platform returns a correct URL to the AS.
And 4, step 4: the AS forwards the SIP message to the called terminal.
Step 203: the calling terminal sends SIP INVITE a call request to the called terminal; the SIP INVITE call request is for requesting that the important call be established.
Here, the calling terminal initiates an important call based on the VoLTE voice service to the called terminal, and the method has the following advantages:
(1) before the calling terminal initiates an important call to the called terminal, the calling terminal can set the call to be initiated as the important call and transmit important call information in an SIP Message mode.
(2) The calling terminal can set the caller ID with important call mark displayed when the called terminal receives the incoming call and the ringing bell corresponding to the important call played when the called terminal receives the incoming call, which can meet the personalized customization requirement of the user.
(3) After receiving the SIP message, the called terminal sends a response message aiming at the SIP message, namely a message delivery report, to the calling terminal after waiting for the successful download of the first multimedia file corresponding to the mark of the important call and the second multimedia file corresponding to the ringing ringtone of the important call.
(4) The method can be combined with the mainstream call service of an operator such as the VoLTE service, can follow the VoLTE routing principle of the current network to the maximum extent, and does not need to change the routing of the current network service.
(5) The calling terminal adopts an HTTP mode to open and order important call services, select marks of important calls and select ringing tones of the important calls on a service management platform.
In practical application, because a plurality of calling terminals can initiate an important call to the same called terminal, the calling terminals can initiate the important call to the called terminal, and in order to avoid that the called terminal cannot identify the important call initiated by the current calling terminal, the calling terminals can carry the same important call identifier in the SIP message and the SIP INVITE call signaling, so that the called terminal and the current calling terminal can establish the important call.
Based on this, in one embodiment, the SIP message contains an identification of an important call; the calling terminal sends SIP INVITE a call request to the called terminal, including:
the calling terminal carries the identification of the important call contained in the SIP message in the SIP INVITE call request;
the calling terminal sends SIP INVITE a call request to the called terminal;
wherein the SIP INVITE call request is used for the called terminal to establish an important call based on a specific voice service with the calling terminal if the identification of the important call carried by the SIP INVITE call request matches the identification of the important call carried by the SIP message.
In an example, as shown in fig. 5, a procedure for a calling terminal to initiate call setup to a called terminal is described, which includes:
step 501: the calling terminal carries the identification of the important call contained in the SIP message in the SIP INVITE call request;
here, the identity of the important call contained in the SIP message is represented by an important id field. The SIP INVITE call may also carry the Feature Tag ICSI Tag field for important calls.
Step 502: the calling terminal sends SIP INVITE a call request to the called terminal.
Here, the called terminal establishes an important call based on a specific voice service with the calling terminal in a case where the identity of the important call carried by the SIP INVITE call request matches the identity of the important call carried by the SIP message.
Here, the calling terminal sends SIP INVITE a call request to the called terminal, which has the following advantages:
when a calling terminal triggers a specific voice service such as a VoLTE service, SIP INVITE signaling sent by the calling terminal to a called terminal needs to carry an import id field which is the same as an SIP message, so as to ensure that the called terminal establishes an important call with the current calling terminal.
By adopting the technical scheme of the embodiment of the invention, the calling terminal can transmit important call information to the called terminal by using the SIP message in a specific voice service scene so as to initiate an important call to the called terminal, and the signaling interaction required by the calling terminal and the called terminal for establishing the important call is less, so that the signaling overhead can be saved.
