Technical field

The present invention relates to the field of communications, and in particular, to a session control method, system, and terminal.

Background technique

Circuit Switch (CS) and IP Multimedia Subsystem (IMS) Fusion Service (CSI or CSICS, CSI, hereinafter referred to as CSI) is a traditional circuit business. Expansion, this new type of service combines the voice services of mutually independent circuit domains in the traditional network with the data services of the data domain, allowing a multimedia session to be added during a normal voice call, and the CSI terminal can associate the two sessions. Presented to the end user as a task. The CSI service utilizes the high scalability of the multimedia session. While the ordinary voice session is being performed, the two parties can use the multimedia session to share pictures, video images, and even audio multimedia files. The CSI business enriches the performance model of voice calls and enriches people's communication methods.

The general call flow of the CSI service is as shown in FIG. 1 , and the steps are as follows: Step 101: The user terminal (UE) A and the user terminal B establish a circuit domain call;

Step 102: User terminal A and user terminal B perform IMS capability interaction, and the interaction content includes a CSI terminal mobile user integrated service digital network number (MSISDN) and a session initial protocol-uniform resource identifier (SIP-URI) association relationship and terminal capability. information. The terminal capability information is used to identify a service set that can be successfully invoked when a session is established between users, including: an IMS streaming media type, a media format parameter supported by the IMS media type, such as a codec format and a media file format. In addition, the user terminal can also interact with the following capability information through the IMS network: the capabilities of the circuit domain video telephony, the capabilities of the circuit domain voice telephony, the capabilities of multimedia messaging, and other IMS-based service capabilities, such as push-to-talk over cellular (PoC), etc. ;

Step 103: The user terminal A triggers the IMS service, and sends a session invitation (INVITE) message to the user terminal B through the IMS network A, and the media attribute is marked as "inactive";

Step 104: IMS network A transmits an INVITE message to the IMS network B; Step 105: IMS network B transmits an INVITE message to user terminal B;

Step 106: The user terminal B associates the received INVITE message with the CS service being used according to the correspondence between the MSISDN and the SIP-URI obtained when the IMS capability interacts in step 102. If the user terminal B sets the automatic answering, the user terminal B side directly initializes the connection access network (IP-CAN) based on the Internet Protocol, and establishes a bearer; otherwise, the bearer is started from step 115;

Step 107: The user terminal B sends 200 OK information to the IMS network B, and the media attribute is marked as "inactive";

Step 108: IMS network B sends 200 OK information to IMS network A;

Step 109: IMS network A sends 200 OK information to user terminal A;

Step 110: The user terminal A feeds back the response information of the received 200 OK message to the IMS network A, and at the same time, the user terminal A side initializes the media attribute to establish an IP-CAN bearer;

Step 111: IMS network A sends response information to IMS network B;

Step 112: IMS network B sends response information to user terminal B;

Step 113: After the IP-CAN is established on the user terminal A side, the user terminal A sends the INVITE information to the IMS network A again, and the media attribute is marked as "active";

Step 114: IMS network A sends INVITE information to IMS network B;

Step 115: IMS network B sends the INVITE information to the user terminal B;

Step 116: The user terminal B performs a corresponding service action, such as establishing a real-time transport protocol (RTP) media channel, starting the codec device, and receiving or transmitting the user media stream;

Step 117: After the IP-CAN bearer of the user terminal B is established, the user terminal B sends 200 OK information to the IMS network B, and the media attribute is marked as "active";

Step 118: IMS network B sends 200 OK information to IMS network A;

Step 119: IMS network A sends 200 OK information to user terminal A;

Step 120: After receiving the 200 OK message, the user terminal A sends a response message to the IMS network A. Step 121: The IMS network A sends the response message to the IMS network B.

Step 122: IMS network B sends response information to user terminal B; Step 123: The multimedia session of the two parties is established.

After the above steps, the two parties can use the established multimedia to share pictures, video images and audio multimedia files. For example, video sharing technology is the application of CSI services, allowing users to share a video while making a voice call.

As shown in FIG. 2, the user terminal that implements the above call flow includes a CS communication module and an IMS communication module, which are respectively used to establish a session between the CS domain and the IMS domain. In addition, on the basis of FIG. 2, the recording module is further included. As shown in FIG. 3, the user terminal is the information sent by the recording sender, where the recording module is connected to the IMS communication module, and is used for recording the IMS communication module. Information.

From the above, the implementation method of the multimedia session is specified in the CSI service, but the copyright and content protection problems that may occur during the multimedia session are not solved.

For example, during the video sharing process, one sender is used to send video media, and one receiver can receive video media and save the video media. The CSI service clearly stipulates that all files with DRM copyright protection are not allowed to be sent. Only files without DRM copyright protection are considered to be uncontrolled and can be sent or forwarded by the sender. However, even if the sender sends a file without DRM copyright protection or uses the camera for live video sharing, the sender may not want the receiver to record and save the shared content, especially the shared content involves personal or other people's privacy. This will bring a certain degree of potential harm to users who share video on the sending side.

In summary, the purpose of the CSI service is to enrich the means of interaction between user terminals, but once the functionality provided by the CSI service exceeds the original expectations (such as recording the received shared video), this must be The function is controlled and managed to prevent this extra function from causing harm.
