Description

Method and device for processing calling information before call, server and terminal

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method, an apparatus, a server, and a terminal for processing caller information before a call.

Background

The current calling name card service is generally realized based on an Application (APP) mode, the APP needs to be installed, and usually, only simple enterprise calling name display is supported for a non-local terminal storage number, part of the calling name card service can display enterprise identification, and information display such as text content and pictures is not supported, and multimedia information such as text content (such as a call theme) and pictures before call matched with the content cannot be set for each call condition.

On the other hand, the concept of enhanced call (RCS) service is proposed in the Rich Communication Services (RCS) specification. The concepts of Pre-call (Pre-call), In-call (In-call) and Post-call (Post-call) are proposed for different stages of the call. The Pre-call service defines the ability of a calling user to push text, pictures, positions and important call marks to a called user before a call. In the international standard scheme, a calling user sets information before a call is made, then synchronizes to a called terminal through a Message Session Relay Protocol (MSRP) Message tunnel, and makes a call to the called terminal after confirming that the terminal finishes information downloading.

However, the Pre-call service only supports calling to set the call theme, picture and location information, and does not support the display of the calling name for a while. And the content that the called user sees in the Pre-call business is all that is input by the caller directly, and will demonstrate directly in the ringing phase, there are several problems as follows: (1) the calling party utilizes the characteristic that the information before the call can be directly displayed on a ringing interface of the called party, and calls the called party after the harassment information is edited to form the forced harassment. (2) The caller imitates certain enterprise names and identifications and sends the enterprise names and the identifications to the called party for showing, and convenience is brought to fraud. (3) The calling party needs to be set before talking each time, so that the use is inconvenient and the user experience is not good. And the Pre-call service is based on the MSRP tunnel for message transmission, there are 2 problems as follows: (1) the use of the MSRP tunnel has a large signaling overhead and is not suitable for operators with large user or service volume. (2) And because initial negotiation of the tunnel needs to be performed, the time delay is large, and the user experience is poor.

Detailed Description

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1, an embodiment of the present invention provides a method for processing pre-call calling information, which is executed by a first server (the first server may also be referred to as a pre-call service server), and includes:

step 101, acquiring a first call request message of a calling terminal;

102, under the condition that a calling terminal signs a service before conversation, sending a first conversation initiation protocol (SIP) message to a called terminal according to the first calling request message; wherein, the first SIP message comprises: calling related information which needs to be displayed by the called terminal in the call and a service mark before the call.

In the embodiment of the invention, the service before conversation is specifically related information of calling related information displayed on a ringing interface of a called terminal.

The embodiment of the invention uses the method of SIP Message to transmit the setting of the relevant information of the calling party, the time delay is lower, and the network overhead is smaller; the embodiment of the invention is realized based on VoLTE, and calling related information can be displayed on a ringing interface of the called terminal without installing any APP at the calling terminal and the called terminal.

Optionally, the caller related information to be displayed by the called terminal includes at least one of the following: a caller name; a call topic; call content introduction (text); a picture set by the caller; a video set by the caller; a position. Or, all display information in the calling related information is displayed on the called terminal in a webview (web view) manner, where the display information includes key information content to be displayed, page description information of the webview, and the like, and is not limited specifically herein. The embodiment of the invention supports rich information display and can comprehensively meet the requirements of users.

As an alternative embodiment, step 102 comprises:

receiving the first call request message sent by a calling terminal;

or,

Bearing the above example, after sending the first SIP message to the called terminal if the first server directly receives the first call request message, the method further includes:

and/or the presence of a gas in the atmosphere,

Or, after the first server obtains the first call request message through forwarding of the first network device, and sends the first SIP message to the called terminal, the method further includes:

Optionally, in this embodiment of the present invention, the second call request message includes a service tag before call.

It should be noted that, in the embodiment of the present application, the second call request message may or may not carry the pre-call service flag. The service mark before the call is used for assisting the called terminal to judge whether the call has service setting before the call, if the called terminal analyzes the service mark before the call, the call is determined to have the service setting before the call, and if the called terminal does not analyze the service mark before the call, the call is determined to have no service setting before the call. The first SIP message carries the pre-call service identifier, but in a special scenario, for example, the called terminal does not resolve the pre-call service identifier in the first SIP message, or the called terminal receives the second call request message before receiving the first SIP message, the called terminal may determine whether the pre-call service setting exists in the call according to the pre-call service identifier in the second call request.

As an alternative embodiment, step 102 comprises:

and sending the first SIP message to the called terminal.

In the embodiment of the invention, the calling information configuration content before the call is preset by the calling terminal, the calling terminal can preset a plurality of sets of calling information configuration content before the call, and the first server can selectively push the content according to the first call request message. If the calling related information required to be displayed by the called terminal in the call is selected according to the setting requirements of the called number, the sending time, the calling state, the group in the group where the calling is located and the like.

Correspondingly, the method further comprises the following steps:

In the embodiment of the invention, the calling information configuration content is uploaded to a first server by a calling terminal in advance before communication, and the first server checks the configuration content; therefore, the calling related information pushed to the called terminal by the first SIP message by the subsequent first server is authenticated or audited, and the method is safe and reliable for the called user.

For example, regarding the calling name in the calling related information, the first server performs identity authentication according to a file containing legal effectiveness provided by the calling terminal, and the authentication can be presented to the called terminal after passing.

Regarding a calling terminal which signs (or is called as opening) a service before a call:

the terminal which opens the pre-call service can set a portal or a client manager through the pre-call service application server. Each piece of setting needs to correspond to at least one set of calling information configuration content before conversation, the content needs to be uploaded to a first server in advance, and the content and the corresponding setting take effect after the first server conducts security verification.

As an alternative embodiment, after sending the first SIP message for n1 seconds, sending a second call request message to the called terminal; n1 is greater than or equal to 0; the calling terminal opening the service before the call directly initiates the call, and the first server does not wait for the delivery report of the first SIP message; however, in order to ensure that the called terminal can display the content before the call before the called terminal rings, the first server may add a timer before sending the second call request message, configure n1 seconds after sending the first SIP message, and then send the second call request message; n1 is greater than or equal to 0;

and/or after receiving a delivery report of a first SIP message sent by a called terminal, sending the second call request message to the called terminal; the delivery report is used for indicating that the content synchronization before the call is successful or fails; the first server sends a second call request message to the called terminal after waiting for the delivery report of the first SIP message; optionally, to improve the user experience, a timeout timer may also be added here, and when the delivery report of the called terminal is not received after the set time of the timer is exceeded, the server does not wait any more, and directly executes the next step, that is, sends the second paging request message.

It should be noted that, after sending the second call request message, the first server receives a second response message of the second call request message fed back by the called terminal, and transparently transmits the subsequent session initial media negotiation flow message.

Bearing in mind the above example, the method further comprises:

forwarding the delivery report to the calling terminal. In order to improve user experience, when the delivery report indicates that the content synchronization before the call fails, the first server may forward the delivery report to the calling terminal through an SIP message, and notify the calling terminal that the content push before the called side call fails. After receiving the delivery report, the calling terminal can prompt the calling user that the content push fails before the called side calls on the interface of the calling terminal.

As another optional embodiment, the embodiment of the present invention further supports adding corresponding information to the calling information before the call according to the real-time requirement of the calling. The realization method is that before the calling party initiates the first calling request message, the calling terminal sends the real-time information before the call to the first server through the SIP message, then the first server carries out safety check aiming at the received content and the preset template definition, and after no problem exists, the first server sends the information to the called terminal according to the normal flow. Namely, before sending the first SIP message to the called terminal, the method further includes:

receiving a second SIP message sent by a calling terminal, wherein the second SIP message comprises: real-time information set by a calling terminal and required to be displayed by a called terminal in the call, and a service mark before the call;

Similarly, the calling terminal that opens the pre-call service carries real-time information to initiate a call, and the server side may directly send the second call request message to the called terminal without waiting for the delivery report of the SIP message, or may send the second call request message to the called terminal after waiting for the delivery report of the SIP message, which is not described repeatedly herein.

Optionally, the pre-call real-time information is sent in a preset template mode and a mode of setting real-time information by the aid of a terminal; by adopting the scheme, on one hand, the information before the call is ensured to be subjected to safety audit, and the identity of the calling party can be verified and displayed to the called terminal, so that the potential safety hazard problem is solved; on the other hand, the method supports the setting of real-time information of the calling side while presetting the content, and is more flexible and convenient for users to use.

For example, the first server finds a prefabricated template according to the message body of the second SIP message carrying the pre-call service configuration information template number, and verifies the received real-time information according to the requirement for inserting the real-time information in the preset template. And if the verification is passed, filling the real-time information into the corresponding pre-call information template, and then putting the real-time information into the message body of the first SIP message.

As an optional embodiment, after receiving the second SIP message sent by the calling terminal, the method further includes:

In the embodiment of the invention, the calling information display service before the call also supports the calling terminal to display the real-time information of the calling before the call to the called terminal, for example, a courier serving as a calling user pushes the calling information before the call containing the sent information to the called terminal. For the situation, the calling user needs to upload the template content of the display information to the server in advance for auditing, and meanwhile, format description is performed on data needing to be transmitted in real time in the template, so that when the real-time data is transmitted in a call, the server checks the real-time data. If in an express scene, the real-time data is the recipient pickup address and the delivery time, and the real-time data can be manually input through a calling terminal or can be obtained by scanning an express single barcode through a terminal and selecting from preset contents in the terminal. When the server verifies that the real-time content is address data and time data but not other content data, the real-time content can be merged with the server side template data through verification and then pushed to the called terminal.

It should be noted that, at the core network/server side, the pre-call service is a value-added call service implemented on the basis of VoLTE call. The triggering rules of IMS VoLTE calls are followed. After the pre-call service is opened, when the calling terminal is the terminal signing the pre-call service, the IMS core network routes the call request initiated by the terminal to the first server, and then the first server provides the corresponding service.

On the side of the terminals (calling terminal and called terminal), the pre-call service is identified by the pre-call service Tag (Feature Tag) of the header fields of the SIP message and the call request message.

The method for indicating the pre-call service mark by the SIP message and the call request message comprises the following steps: for the SIP message and the call request message of the pre-call Service, the Feature Tag ICSI Tag of the important call should be carried in the Accept-Contact or Contact header field, and the Feature Tag ICSI Tag of the pre-call Service is also carried in the P-Preferred-Service or P-Asserted-Service header field. In addition, a pre-call ID field needs to be carried to ensure that the called terminal can match the call request with the SIP message.

In summary, the embodiment of the present invention can display reliable caller related information including caller name, call subject, caller setting picture/video, location, etc. on the called terminal interface when the called terminal rings; the embodiment of the invention supports that the calling user uploads the information before the call in advance after ordering the service before the call, and pushes the relevant information of the calling before the corresponding call for the called party under different conditions according to the definition of the calling user; in some scenes, the calling information before the call can carry the content edited by the calling side in real time; therefore, the synchronization of the information before the call is realized by using a mode of shorter time delay.

As shown in fig. 2, an embodiment of the present invention further provides a method for processing calling information before a call, which is executed by a called terminal, and includes:

step 201, receiving a first SIP message sent by a first server, where the first SIP message includes: calling related information needing to be displayed by a called terminal in the call and a service mark before the call;

step 202, receiving a second call request message sent by a first server or a first network device;

step 203, completing the call media negotiation with the calling terminal according to the second call request message, sending a ringing notification and displaying the calling related information in the first SIP message on a ringing interface.

In the embodiment of the invention, the called terminal receives the first SIP message, and the header field of the first SIP message carries the service mark before the call, so that the calling related information to be displayed before the call is acquired from the message body of the first SIP message.

For example, the called terminal determines whether the calling related information includes a content to be downloaded, such as a picture, a video, and the like, and if so, completes content downloading according to the download link and completes display presetting of the calling related information before the call. Optionally, in order to protect the performance of the terminal, after the terminal completes the pre-call information presetting, a timer is set, and after the timer expires, if the pre-call content setting requirement corresponding to the call request message has not been received, the terminal deletes the display content of the pre-call information.

The called terminal receives the second call request message, the header field of the second call request message carries the service mark before the call, and the called terminal sets the first SIP message association with the service mark before the call and the content before the call received before the call through the calling number and the called number.

And the calling party and the called party finish media negotiation, the called party confirms that the calling information is preset before the call, the called terminal sends 180 information to the calling terminal, and the called terminal indicates the preset calling related information before the call through a first SIP message before local ringing and display. Optionally, in order to improve user experience, the terminal may set a timer, and if the terminal completes media negotiation after receiving the second call request message or after completing the initial media negotiation for the call, and when the terminal completes media negotiation to prepare for ringing, if the calling information before the call is not yet preset, the terminal waits for the presetting of the calling information before the call before the timer expires, the preset completes ringing again, displays the content before the call, and sends a 180 message, and if the terminal does not complete the presetting of the calling information before the call after the timer expires, the terminal abandons the displaying of the calling information before the call, and directly performs local ringing and sends the 180 message to the calling. Further, the called party is off-hook, and the calling party and the called party are in communication.

Optionally, the second call request message includes a pre-call service flag.

As an alternative embodiment, step 203 comprises:

after the call media negotiation is completed, sending a ringing notification; and after the called terminal finishes the preparation of the calling related information before the call, the calling related information in the first SIP message is displayed on a ringing interface.

In other words, the called terminal knows that the current call contains the pre-call service from the pre-call service tag in the first SIP message header or the pre-call service tag in the second call request; after receiving the second call request message, the called terminal continues to complete call media negotiation with the calling terminal, and after completing the call media negotiation, judges whether a service mark before conversation exists, and then rings and displays calling related information on a local ring interface. Or, when the called terminal finds that the call has a pre-call service, (may know from the pre-call service tag in the received first SIP message, or may know from the pre-call service tag in the second call request message, and see that the message arrives at the called terminal first), it needs to complete the initial media negotiation, that is, when sending the ring notification, start the timer, and when the timer is over time and the called terminal has not completed the preparation of the pre-call service calling related information, the called terminal gives up displaying the pre-call calling information, directly returns the ring message, and locally rings, and does not display the calling information.

As an alternative embodiment, after step 201, the method further comprises:

As another optional embodiment, the first SIP message further includes: real-time information set by the calling terminal and required to be displayed by the called terminal in the call;

the method further comprises the following steps:

In summary, the embodiment of the present invention can display reliable caller related information including caller name, call subject, caller setting picture/video, location, etc. on the called terminal interface when the called terminal rings; the embodiment of the invention supports that after a calling party orders a pre-call service, pre-call information is uploaded in advance, and corresponding pre-call calling related information is pushed for a called party under different conditions according to the definition of the calling party; in some scenes, the calling information before the call can carry the content edited by the calling side in real time; therefore, the synchronization of the information before the call is realized by using a mode of shorter time delay.

As shown in fig. 3, an embodiment of the present invention further provides a method for processing calling information before a call, which is executed by a calling terminal, and includes:

step 301, after signing a pre-call service with a first server, configuring at least one set of pre-call calling information configuration content with the first server; the first server carries out security audit on the calling information configuration content before the call;

step 302, a first call request message for calling the called terminal is sent.

the terminal which opens the service before the call can set the external portal or the client manager through the service application server before the call. Each piece of setting needs to correspond to at least one set of calling information configuration content before conversation, the content needs to be uploaded to a first server in advance, and the content and the corresponding setting take effect after the first server conducts security verification.

As another optional embodiment, the embodiment of the present invention further supports adding corresponding information to the calling information before the call according to the real-time requirement of the calling. The realization method is that before the calling party initiates the first calling request message, the calling terminal sends the real-time information before the call to the first server through the SIP message, then the first server carries out safety check aiming at the received content and the preset template definition, and after no problem exists, the first server sends the information to the called terminal according to the normal flow. I.e. before step 302, the method further comprises:

As another alternative embodiment, before transmitting the first call request message for calling the called terminal, the method further includes:

Similarly, for the second SIP message, the calling terminal may send the first call request message directly without waiting for a response message (also referred to as a delivery report) of the second SIP message; for example, to ensure that the called terminal can display the content before the call before the called terminal rings, the terminal may add a timer before sending the first call request message, configure n seconds after sending the second SIP message, and then send the first call request message; or, the calling terminal may also wait for receiving the response message of the second SIP message and then send the first call request message; or, in order to improve the user experience, a timeout timer may be added, and when the delivery report of the second SIP message is not received after the set time of the timer is exceeded, the calling terminal does not wait any more, and directly executes the next step, that is, sends the first call request message.

As another optional embodiment, before sending the second SIP message, the method further comprises:

inputting freely through a keyboard;

selecting preset content through a calling terminal interface;

the device obtains the two-dimensional code or the bar code by scanning.

For example, the calling terminal sets real-time information to be displayed before a call, packages the real-time information in a message body of the second SIP message, and sends the message body to the first server. The header field of the second SIP message carries the pre-call service tag. Here, the real-time information set by the calling terminal may be freely input by the calling user through a mobile phone keyboard, may also be preset content selected through a terminal interface, may also be content obtained by the terminal device by scanning a two-dimensional code/barcode, and may also be content obtained by the terminal device by some other means. For filling in real-time information before a call, a calling terminal needs to carry at least the following key contents: (1) the real-time information corresponds to the information template before the call, and (2) the real-time information.

The application scenarios are exemplified as follows:

and the courier sends a scene of express calling to the client. At present, express companies usually have own special terminals or apps, and the customer mobile phone numbers are obtained by scanning bar codes on express bills and then directly send short messages or make calls. For a calling scene, after a courier dials a call, a called receiver mobile phone displays an unfamiliar number when ringing, although the scene is optimized for certain brands of mobile phones or APPs, number category identification of 'express delivery' can be added below the unfamiliar number in a user marking mode, on one hand, the number identification is not authenticated and is not safe enough, and sometimes, a marking error condition occurs; on the other hand, only large classes can be marked, which express company cannot be determined, and after the express company is frequently hung up, the express company does not remember which courier to go to and take the express, and secondary call back confirmation is needed. After the service before the call provided by the embodiment of the invention is used, the called terminal can accurately identify the identity of the caller, xx express company, meanwhile, the express company can directly tell the user where the express is going to be distributed (an express receiving address, which may be a home or a company, avoids the confusion of the user) through the text content before the text call, and can display the information of company logo or recent consignment preferential activities and the like through pictures to publicize the company.

As shown in fig. 4, an embodiment of the present invention further provides a method for processing caller information before a call, which is executed by a first network device, and includes:

step 401, receiving the first call request message sent by the calling terminal;

step 402, forwarding the first call request message to a first server;

step 403, sending a second call request message to the called terminal.

As an alternative embodiment, step 403 includes:

under the condition of receiving a first response message fed back by the first server, sending a second call request message to the called terminal; the first network equipment sends a second call request message to the called terminal after receiving the first response message; optionally, in order to improve user experience, a timeout timer may also be added here, and when the first response message of the first server is not received after the set time of the timer is exceeded, the first network device does not wait any more, and directly executes the next step, that is, sends the second paging request message;

and/or the presence of a gas in the gas,

sending a second call request message to the called terminal after forwarding the first call request message to the first server for n2 seconds; n2 is greater than or equal to 0; after the first network device forwards the first call request message to the first server, the first network device does not wait for a response message of the first call request message; however, to ensure that the called terminal can display the content before the called terminal rings for the pre-call, the first network device may add a timer before sending the second call request message, and configure to send the second call request message n2 seconds after forwarding the first call request message.

Optionally, in this embodiment of the present invention, the second call request message includes a pre-call service flag.

In summary, in the embodiment of the present invention, the first network device forwards the first call request message to the first server, and the first server sends the relevant calling information to the called terminal through the SIP message, so that reliable relevant calling information, including information such as a calling name, a call topic, a calling setting picture/video, and a location, can be displayed on an interface of the called terminal when the called terminal rings.

In order to more clearly describe the method for processing the pre-call calling information provided by the embodiment of the present invention, the following description is made with reference to two examples.

Example one, as shown in fig. 5, a calling terminal that opens a pre-call service directly initiates a call

1. The terminal a (here, as the user a, is the calling party) has opened the pre-call service and completes the content setting of the pre-call service. Terminal a sends an initial call request (i.e., invite message).

2. Since the user a has opened the pre-call service, the call request sent by the terminal a will be sent to the first server (hereinafter referred to as server or platform) by the IMS core network. The server judges the service before the user A signs the contract, and the system confirms the information of the calling user before the call which needs to be synchronized to the called side at present according to the current call state, such as the information of the calling user number, the called user number, the call initiation time and the like. The platform encapsulates the pre-call content setting requirement in the message body of the SIP message, and the message head carries the pre-call service mark and sends the pre-call service mark to the called user, namely the terminal B.

3. And after receiving the SIP message, the terminal B finds that the message header carries the service mark before the call, reads the corresponding set content in the message body, and presets display information before the call. After receiving the SIP message, the terminal B replies a 200OK response message.

And 4-5, selecting a flow, and if the content setting requirement before the call comprises the contents needing to be downloaded, such as pictures, videos and the like, finishing content downloading and finishing display presetting of calling information before the call by the terminal according to the downloading link. Optionally, in order to protect the performance of the terminal, the terminal sets a timer after completing the pre-call information presetting, and if the timer is overtime and does not receive the pre-call content setting requirement corresponding call request message, the terminal deletes the display preset content of the pre-call information. If the content setting requirement before the call does not contain the content such as pictures, videos and the like which need to be downloaded, the step does not exist.

6-9, which is also an optional procedure here. And after the called terminal finishes downloading and displaying the calling information before the call and presets, sending a delivery report of the SIP message (content display receipt before the call) to the calling side. After receiving the delivery report, the server forwards the report to the calling terminal. The steps can be optionally realized here: (1) the display of the calling information before the call is a value-added function of the basic call, and whether the calling information can be successfully displayed or not cannot influence the normal call, so that the terminal does not need to report to a service platform or the calling terminal when the content is successfully downloaded or displayed. (2) In order to improve the service experience, the calling party can perceive the service state, and the service state can be informed through a receipt message. The experience is further improved, only the condition that the display of the calling information fails before the call is informed, and the calling does not receive the receipt, which indicates that the information is normally displayed on the called side.

10. If the flow containing the delivery report is adopted, the server receives the delivery report of the called terminal and then forwards the call request of the calling terminal, and the head domain can carry the service mark before the call. If the flow containing the delivery report is not adopted, the service application server before the call forwards the call request after receiving the SIP message 200OK required by the service setting before the call.

11. Following the existing VoLTE call flow, the calling party and the called party continue to complete the call initial media negotiation.

12-14, the called terminal judges that the call has the service setting before the call according to the service mark before the call carried in the call request. When sending the ringing notification, the terminal needs to first judge whether the downloading and setting of the calling information before the call is finished, if so, the terminal sends the ringing notification to the calling, and simultaneously displays the calling information content before the call on a local ringing interface. If the terminal has not received the setting information notification of the content before the call after completing the call negotiation or has not completed the downloading of the content, the terminal needs to send the ringing notification to the calling party after completing the downloading of the content before the call, and simultaneously, the calling information content before the call is displayed on the ringing interface of the terminal.

Optional optimization implementation: and the terminal judges that the call has pre-call service setting according to the pre-call service mark carried in the call request, and then the terminal needs to start a pre-call service timer. When the terminal does not receive the setting information notification of the content before the call after completing the call negotiation, or does not complete the downloading of the content, and the service timer before the call is not overtime, the terminal waits for the completion of the downloading of the content before the call, sends a ringing notification to the calling party after the downloading is successful, and simultaneously displays the information content of the calling party before the call on a ringing interface of the terminal; if the service timer is overtime before the call, the terminal does not wait for the downloading of the content before the call, and directly sends a ringing notification to the calling party, and the local ringing interface does not show the information of the calling party before the call.

And 15-16, the called terminal picks up the phone, sends a pickup 200OK message to the calling terminal, and switches the called terminal into a call interface.

Example two, as shown in fig. 6, the calling terminal that has opened the pre-call service directly initiates a call

2. Because the user A opens the service before the call, the call request sent by the terminal A reaches the first network equipment; the first network device terminal a is notified of the call event to the first server (hereinafter referred to as server or platform).

3. The server sends a response message of the call event notification to the first network equipment;

4. the server judges the service before the user A has signed a contract for a call, and the system confirms the information of the calling user before the call which needs to be synchronized to the called side at present according to the current call state, such as the information of the calling user number, the called user number, the call initiation time and the like. The platform encapsulates the pre-call content setting requirement in the message body of the SIP message, and the message head carries the pre-call service mark and sends the pre-call service mark to the called user, namely the terminal B.

5. And after receiving the SIP message, the terminal B finds that the message header carries the service mark before the call, reads the corresponding set content in the message body, and presets display information before the call. After receiving the SIP message, the terminal B replies a 200OK response message.

6-7, which is an optional flow, if the content setting requirement before the call contains the contents needing to be downloaded, such as pictures, videos and the like, the terminal finishes content downloading and finishes the display presetting of calling information before the call according to the downloading link. Optionally, in order to protect the performance of the terminal, the terminal sets a timer after completing the pre-call information presetting, and if the timer is overtime and does not receive the pre-call content setting requirement corresponding call request message, the terminal deletes the display preset content of the pre-call information. If the content setting requirement before the call does not contain the content such as pictures, videos and the like which need to be downloaded, the step does not exist.

8-11, which is also an optional procedure here. And after the called terminal finishes downloading and displaying the calling information before the call and presets, sending a delivery report of the SIP message (content display receipt before the call) to the calling side. After receiving the delivery report, the server forwards the report to the calling terminal. The steps can be optionally realized here: (1) the display of the calling information before the call is a value-added function of the basic call, and whether the calling information can be successfully displayed or not cannot influence the normal call, so that the terminal does not need to report to a service platform or the calling terminal when the content is successfully downloaded or displayed. (2) In order to improve the service experience, the calling party can perceive the service state, and the service state can be informed through a receipt message. And the experience is further improved, only the condition that the display of the calling information fails before the call is informed, and the calling does not receive the receipt, which indicates that the information is normally displayed on the called side.

12. The first network device receives the response message of the server and then forwards the call request of the calling terminal, and the header field can carry the service mark before the call.

13. Following the existing VoLTE call flow, the calling party and the called party continue to complete the call initial media negotiation.

And 14-16, the called terminal judges that the call has the service setting before the call according to the service mark before the call carried in the call request. When sending the ringing notification, the terminal needs to first judge whether the downloading and setting of the calling information before the call is finished, if so, the terminal sends the ringing notification to the calling, and simultaneously displays the calling information content before the call on a local ringing interface. If the terminal has not received the setting information notification of the content before the call after completing the call negotiation or has not completed the downloading of the content, the terminal needs to send the ringing notification to the calling party after completing the downloading of the content before the call, and simultaneously, the calling information content before the call is displayed on the ringing interface of the terminal.

And 17-18, the called terminal picks up the phone, sends a pickup 200OK message to the calling terminal, and switches the called terminal into a call interface.

Example three, as shown in fig. 7, the calling terminal that opened the pre-call service carries real-time information to initiate a call request

1. The calling user sets the content before real-time conversation, packages the content in the message body of the SIP message and sends the content to the called user. The SIP message header field carries the pre-call service tag. Here, what the calling user sets is the content before the real call, which can be freely input through a mobile phone keyboard by the calling user, or preset content selected through a terminal interface, or content obtained by scanning a two-dimensional code/barcode by the terminal device, or content obtained by the terminal device through some other method. For filling in real-time information before a call, a calling terminal needs to carry at least the following key contents: (1) the real-time information corresponds to the information template before the call, and (2) the real-time information.

2. The first server identifies that the SIP message header field carries a pre-call service tag. Temporarily storing the SIP message and waiting for the arrival of the corresponding call. And simultaneously returns a SIP message 200OK response message.

3. The calling terminal sends a call request message.

4. Since the user a has opened the pre-call service, the call request sent by the terminal a will be sent to the first server (hereinafter referred to as server) by the IMS core network. The server judges that (1) the calling user signs the service before the call and (2) the configuration information of the real-time information before the call of the calling user is received. And assembling the information setting requirement before the call, and sending the information setting requirement to the called party through an SIP message. The SIP message header field carries the service mark before the call, and the message body carries the information setting requirement before the call.

6-7, which is an optional process, if the content setting requirement before the call contains the content to be downloaded such as pictures, videos and the like, the terminal completes content downloading and display presetting of calling information before the call according to the downloading link. Optionally, in order to protect the performance of the terminal, the terminal sets a timer after completing the pre-call information presetting, and if the timer is overtime and does not receive the pre-call content setting requirement corresponding call request message, the terminal deletes the display preset content of the pre-call information. If the content setting requirement before the call does not contain the contents such as pictures, videos and the like which need to be downloaded, the step does not exist.

8-11, which is also an optional procedure here. And after the called terminal finishes downloading and displaying the calling information before the call and presets, sending a delivery report of the SIP message (content display receipt before the call) to the calling side. After receiving the delivery report, the server forwards the report to the calling terminal. The steps can be optionally realized here: (1) the display of the calling information before the call is a value-added function of the basic call, and whether the calling information can be successfully displayed or not cannot influence the normal call, so that the terminal does not need to report to a service platform or the calling terminal when the content is successfully downloaded or displayed. (2) In order to improve the service experience, the calling party can perceive the service state, and the service state can be informed through a receipt message. The experience is further improved, only the condition that the display of the calling information fails before the call is informed, and the calling does not receive the receipt, which indicates that the information is normally displayed on the called side.

12. If the flow containing the delivery report is adopted, the server receives the delivery report of the called terminal and then forwards the call request of the calling terminal, and the head domain carries the service mark before the call. If the flow containing the delivery report is not adopted, the service application server before the call forwards the call request after receiving the SIP message 200OK required by the service setting before the call.

And 14-16, the called terminal judges that the call has the service setting before the call according to the service mark before the call carried in the call request. When sending the ringing notification, the terminal needs to first determine whether the downloading and setting of the calling information before the call has been completed, and if so, the terminal sends the ringing notification to the calling, and simultaneously displays the content of the calling information before the call on the ringing interface of the terminal. If the terminal has not received the setting information notification of the content before the call after completing the call negotiation or has not completed the downloading of the content, the terminal needs to send the ringing notification to the calling party after completing the downloading of the content before the call, and simultaneously, the calling information content before the call is displayed on the ringing interface of the terminal.
