[0080] Before introducing the technical solution of the embodiment of the present invention, the related technology is first described.

[0081] In the related art, with the rapid development of mobile terminal technology and Internet technology, a calling terminal can initiate a voice call to a called terminal. In actual application, when the calling terminal wants to transmit important information to the 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 to establish an important call with the called terminal. In the related art, the calling terminal initiating an important call has a problem of large signaling overhead.

[0082] Based on this, in various embodiments of the present invention, the calling terminal sends a SIP message to the called terminal; the SIP message is used to indicate that an important call based on a specific voice service is initiated to the called terminal; the calling terminal receives a response message to the SIP message sent by the called terminal; the calling terminal sends a SIP INVITE call request to the called terminal; the SIP INVITE call request is used to request to establish the important call.

[0083] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0084] The embodiment of the present invention provides a call establishment method, such as Figure 1 As shown, the method includes:

[0085] Step 101: The calling terminal sends a SIP message to the called terminal; and receives a response message to the SIP message sent by the called terminal; the SIP message is used to indicate that an important call based on a specific voice service is initiated to the called terminal;

[0086] Step 102: The calling terminal sends a SIP INVITE call request to the called terminal; the SIP INVITE call request is used to request to establish the important call.

[0087] 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 with high transmission rate requirements, or may refer to a voice service in a future fifth-generation mobile communication system. Taking the VoLTE service as an example, when the called terminal triggers the VoLTE service, the calling terminal may transfer the initiated important call to the called terminal through a SIP message, and the signaling interaction between the calling terminal and the called terminal is less, thereby saving signaling overhead.

[0088] Here, in step 102, when the calling terminal triggers the specific voice service, the calling terminal may use the SIP protocol to send a SIP INVITE call signaling to the called terminal to establish an important call.

[0089] In actual application, when the calling terminal initiates an important call to the called terminal, the calling terminal can set the caller ID and ring tone when the called terminal receives the incoming call to remind the called terminal of the importance of the current call.

[0090] Based on this, in one embodiment, the method further includes:

[0091] The calling terminal obtains 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 tone of the important call;

[0092] The calling terminal generates a SIP message based on the URL of the first multimedia file and the URL of the second multimedia file; wherein the URL of the first multimedia file and the URL of the second multimedia file are used for the called terminal to display the mark of the important call and play the ringing tone corresponding to the important call.

[0093] Here, the mark of the important call may refer to the caller ID set by the calling terminal; the ringing tone corresponding to the important call may refer to the ringing tone set by the calling terminal. The first multimedia file corresponding to the mark of the important call may specifically be a picture, etc.; the second multimedia file corresponding to the ringing tone corresponding to the important call may specifically be audio, etc.

[0094] In actual application, the calling terminal can initiate an important call to the called terminal only after it has subscribed to the important call service. Therefore, the calling terminal can subscribe to the important call service on the service management platform and obtain the URLs of the first multimedia file and the second multimedia file from the service management platform.

[0095] Based on this, in one embodiment, the calling terminal obtains 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 tone of the important call, including:

[0096] The calling terminal sends a subscription request to the service management platform; the subscription request is used to request the activation of an important call service;

[0097] The calling terminal receives a response message sent by the service management platform to the subscription request; the response message is used to indicate that the calling terminal is allowed to activate the important call service;

[0098] The calling terminal performs a setting operation for an important call mark and a ringing ringtone to receive the URL of the first multimedia file and the URL of the second multimedia file returned by the service management platform.

[0099] Here, the user using the calling terminal can access the service management platform on the calling terminal. After the important call service is subscribed to on the service management platform, the user can browse and set personalized important call information on the service management platform, for example, activate the important call service, select the important call service package, select the style of the important call mark, select the ringing tone of the important call, etc. After the user sets the important call information, the service management platform can return the URL of the first multimedia file corresponding to the important call mark and the URL of the second multimedia file corresponding to the ringing tone of the important call to the calling terminal. Among them, the important call service package can be set according to the operation needs, for example, monthly / time or daily hours-hours / times, etc.

[0100] In actual application, since the calling terminal sends to 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 tone of the important call, in order to avoid the situation where the call signaling of the calling terminal has been delivered to the called terminal but the called terminal cannot timely display the caller ID and ringing tone of the important call of the calling terminal device, the called terminal can receive the SIP message sent by the calling terminal, and then send a response 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 tone of the important call. In this way, it can be ensured that the called terminal can timely display the caller ID and ringing tone set by the calling terminal when receiving a call from the calling terminal.

[0101] Based on this, in one embodiment, the calling terminal receives a response message to the SIP message sent by the called terminal, including:

[0102] 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 to the SIP message sent by the called terminal.

[0103] In actual application, the calling terminal can send a SIP message to the called terminal through the AS. After the AS receives the SIP message, if the SIP message carries the URL of the first multimedia file corresponding to the important call mark and the URL of the second multimedia file corresponding to the ringing tone of the important call, the service management platform can be requested to review whether the calling terminal has subscribed to the important call service and whether the URL of the first multimedia file and the URL of the second multimedia file are accurate, so as to ensure the quality of the important call initiated by the calling terminal.

[0104] Based on this, in one embodiment, the calling terminal sends a SIP message to the called terminal, including:

[0105] The calling terminal sends a SIP message to the AS;

[0106] The SIP message is sent to the called terminal through the AS.

[0107] Here, the calling terminal sends a SIP message to the AS. After receiving the SIP message, the AS parses the SIP message to obtain the key content carried by the SIP message; and initiates a service review request to the service management platform through a HyperText Transfer Protocol (HTTP) GET message. After receiving the service review request sent by the AS, the service management platform reviews whether the calling terminal has subscribed to the important call service, whether the URL of the first multimedia file and the URL of the second multimedia file are accurate, and returns a review response message to the AS. Among them, if there is no error in reviewing the URL of the first multimedia file and the URL of the second multimedia file, the service management platform returns a response message of successful review to the AS, and the AS forwards the SIP message sent by the calling terminal to the called terminal; if there is an error in reviewing the URL of the first multimedia file and the URL of the second multimedia file, the service management platform returns the correct URL to the AS, and the AS carries the correct URL in the SIP message sent by the calling terminal and forwards it to the called terminal. The AS can also feedback a SIP Message 4XX message to the calling terminal to prompt the calling terminal to re-subscribe to the mark of the important call and the ring tone corresponding to the important call.

[0108] In one example, if Figure 2 The figure shows the process of a calling terminal initiating an important call to a called terminal, including:

[0109] Step 201: The calling terminal generates a SIP message.

[0110] Here, before step 201, when the calling terminal triggers the VoLTE service, the URL of the first multimedia file corresponding to the important call mark and the URL of the second multimedia file corresponding to the ringing tone of the important call can be obtained; and the URL of the first multimedia file is used as the first field, the URL of the second multimedia file is used as the second field, and the important call tag is used as the third field, and a SIP message, i.e., SIPMessage, is generated by the first field, the second field, and the third field.

[0111] 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, it indicates that the current call is a normal call; when the value of the third field is 1, it indicates that the current call is an important call.

[0112] Step 202: The calling terminal sends the SIP message to the called terminal, and receives a response message to the SIP message sent by the called terminal.

[0113] Here, if Figure 3 As shown, the process of the calling terminal sending a SIP message to the called terminal and receiving a response message sent by the called terminal to the SIP message includes:

[0114] Step 1: The calling terminal sends a SIP message to the called terminal;

[0115] Here, the VoLTE call module in the calling terminal sends a notification message to the message module; the notification message is used to instruct the message module to send a SIP message to the called terminal.

[0116] In addition to the conventional SIP message fields, such as the From header field, the To header field, and the Feature Tag ICSI tag of the important call, the XML message body of the SIP message may also carry the Important call field, the Important ID field, the Media URL field, etc. The Important call field corresponds to the third field, and the Media URL field corresponds to the first and second fields.

[0117] Here, the SIP message may specifically be:

[0118]

[0119] Step 2: The called terminal downloads the first multimedia file and the second multimedia file carried in the SIP message.

[0120] Step 3: After downloading the first multimedia file and the second multimedia file, the called terminal sends a response message to the calling terminal in response to the SIP message.

[0121] Here, if Figure 4 As shown, the process of the calling terminal sending a SIP message to the called terminal includes:

[0122] Step 1: The calling terminal sends a SIP message to the AS;

[0123] Step 2: AS initiates a business review request to the business management platform.

[0124] Step 3: The business management platform returns an audit response message to the AS.

[0125] If the URL of the first multimedia file and the URL of the second multimedia file are correct, the business management platform returns a response message of successful review to the AS. If the URL of the first multimedia file and the URL of the second multimedia file are incorrect, the business management platform returns the correct URL to the AS.

[0126] Step 4: AS forwards the SIP message to the called terminal.

[0127] Step 203: The calling terminal sends a SIP INVITE call request to the called terminal; the SIP INVITE call request is used to request to establish the important call.

[0128] Here, the calling terminal initiates an important call based on the VoLTE voice service to the called terminal, which has the following advantages:

[0129] (1) Before the calling terminal initiates an important call with the called terminal, the calling terminal can set the call to be initiated as an important call and use SIP Message to transmit important call information. Compared with the information transmission method based on MSRP tunnel in the related art, it can avoid the additional overhead caused by frequently sending a large amount of message data based on MSRP tunnel. This method is suitable for operators with a large number of users or business volumes.

[0130] (2) The calling terminal can set the caller ID with an important call mark to be displayed when the called terminal receives an incoming call, and the ring tone corresponding to the important call to be played when the called terminal receives an incoming call, which can meet the user's personalized customization requirements.

[0131] (3) After receiving the SIP message, the called terminal sends a response message to the SIP message, i.e., a message delivery report, to the calling terminal after the first multimedia file corresponding to the important call mark and the second multimedia file corresponding to the ringing tone of the important call are successfully downloaded.

[0132] (4) It can be combined with the operator's mainstream call services such as VoLTE services, and can follow the existing VoLTE routing principles to the greatest extent, without making any changes to the existing network service routing.

[0133] (5) The calling terminal uses HTTP to activate and subscribe to the important call service on the service management platform, as well as select the important call mark and the ring tone for the important call.

[0134] In actual application, since multiple calling terminals can initiate important calls to the same called terminal, when the calling terminal initiates an important call to the called terminal, in order to avoid the called terminal being unable to identify the important call initiated by the current calling terminal, the calling terminal can carry the same important call identifier in the SIP message and SIP INVITE call signaling, so that the called terminal can establish an important call with the current calling terminal.

[0135] Based on this, in one embodiment, the SIP message includes an identifier of an important call; the calling terminal sends a SIP INVITE call request to the called terminal, including:

[0136] The calling terminal carries the identifier of the important call included in the SIP message in the SIP INVITE call request;

[0137] The calling terminal sends a SIP INVITE call request to the called terminal;

[0138] The SIP INVITE call request is used by the called terminal to establish an important call based on a specific voice service with the calling terminal when the important call identifier carried in the SIP INVITE call request matches the important call identifier carried in the SIP message.

[0139] In one example, if Figure 5 As shown in FIG. 1 , a process of establishing a call from a calling terminal to a called terminal is described, including:

[0140] Step 501: The calling terminal carries the identifier of the important call included in the SIP message in a SIP INVITE call request;

[0141] Here, the identifier of the important call included in the SIP message is represented by the important id field. The SIP INVITE call may also carry a Feature Tag ICSI tag field of the important call.

[0142] Step 502: The calling terminal sends a SIP INVITE call request to the called terminal.

[0143] Here, the called terminal establishes an important call based on a specific voice service with the calling terminal when the identifier of the important call carried in the SIP INVITE call request matches the identifier of the important call carried in the SIP message.

[0144] Here, the calling terminal sends a SIP INVITE call request to the called terminal, which has the following advantages:

[0145] When the calling terminal triggers a specific voice service such as VoLTE service, the SIP INVITE signaling sent by the calling terminal to the called terminal needs to carry the same important id field as the SIP message to ensure that the called terminal establishes an important call with the current calling terminal.

[0146] By adopting the technical solution of the embodiment of the present invention, the calling terminal can use SIP messages to transmit important call information to the called terminal in a specific voice service scenario to initiate an important call to the called terminal. Since the calling terminal and the called terminal require less signaling interaction to establish an important call, signaling overhead can be saved.

[0147] Correspondingly, the embodiment of the present invention also provides a call establishment method, such as Figure 6 As shown, the method includes:

[0148] Step 601: the called terminal receives a SIP message sent by the calling terminal; and sends a response message to the SIP message to the calling terminal; the SIP message is used to indicate initiation of an important call based on a specific voice service to the called terminal;

[0149] Step 602: The called terminal receives a SIP INVITE call request sent by the calling terminal; the SIP INVITE call request is used to request to establish an important call based on a specific voice service.

[0150] In one embodiment, the SIP message includes 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 tone of the important call; and the response message to the SIP message sent by the called terminal to the calling terminal includes:

[0151] The called terminal downloads a first media file corresponding to the mark of the important call and a second multimedia file corresponding to the ringing tone of the important call according to the URL of the first multimedia file and the URL of the second multimedia file;

[0152] After downloading the first multimedia file and the second multimedia file, the called terminal sends a response message to the calling terminal in response to the SIP message.

[0153] In one embodiment, the SIP message includes an identifier of an important call; and the called terminal receives the SIP INVITE call request sent by the calling terminal, including:
