Shared Service (CSI) is an extension of traditional circuit services. This new type of service combines voice services in the circuit domain and data services in the data domain that are independent of each other in the traditional network, allowing a multimedia session to be added during an ordinary voice call. And a special CSI terminal can associate these two sessions as one task and present it to the terminal user. The CSI service enriches the performance modes of voice calls and enriches people's means of communication. The CSI service utilizes the high scalability of multimedia sessions. While carrying out ordinary voice sessions, the two parties in the dialogue can use this multimedia session to share pictures, video images, and even multimedia files with sound.

There are two kinds of bearers in the CSI service, one is the service bearer of the Internet protocol multimedia subsystem (IMS) network, and the other is the service bearer of the circuit domain (CS) network.

The processing method in the prior art is: only the CS service can be processed, and the IMS service cannot be changed independently. After processing the voice service of the CS network, the terminal will automatically delete the IMS service bearer to avoid additional troubles caused by additional control of the IMS bearer. That is to say, the IMS service is a kind of CS service If the CS service ceases to exist, the IMS service will end accordingly. Therefore, the processing method in the prior art cannot meet various needs of users and reduces the flexibility of media information processing.

Detailed ways

The invention provides a media information processing method, a communication system and a user terminal, which are used to improve the flexibility of media information transfer.

Please refer to Fig. 1, the process flow of the specific embodiment of the method of the present invention includes:

101. The first user performs a CSI call with the second user;

Wherein, a CSI session includes two sessions, one is a CS session, and the other is an IMS session.

102. The first user terminal sends a service change request to the second user terminal;

103. Determine whether the changed service type includes an IMS service, if yes, execute step 104, if not, execute step 105;

104. Change the IMS service according to the service change request;

105. Execute corresponding processing according to the service change request.

When the service to be changed does not include the IMS service, it is considered that the service change request submitted by the user is an illegal request, and then the processing flow of the present invention is ended. It can be understood that after the process of the present invention is completed, the service change request can be processed in the prior art. For example, when the user requests to change the CS service, the processing process can specifically be to change the CS service and terminate the IMS service.

In addition, if it is stipulated that the change service type selected by the user must include the IMS service, then the judgment step in the above embodiment can be omitted, and the second user terminal directly performs corresponding processing according to the service change type selected by the user, that is, the second user terminal As long as it is identified that the service requesting change includes the IMS service, corresponding processing can be performed.

The service change in the specific embodiment of the present invention is described by business transfer and service maintenance. It can be understood that the service change request may also be other similar service changes.

Referring to Fig. 2, the first embodiment of the present invention is described below. In this embodiment, the business change is business transfer:

201. The first user performs a CSI call with the second user;

202. When the user needs to perform service transfer, the first user terminal sends a service transfer request REFER including the transfer service type and destination device address to the second user terminal.

The message format of REFER is shown in the following table:

Table 1

REFER sip:batlanta.example.com SIP/2.0 Session Initiation Protocol (SIP, Session Initiation Protocol) method type, 2.0 refers to the IETF 3261 standard version, sip:batlanta.example.com is the called terminal number in SIP-URI format Via: Identify the path node through which the message is transmitted in the network To:<sip:batlanta.example.com> Called user information From:<sip:aatlanta.example.com>; tag＝193402342 caller information Call-ID:898234234agenta.atlanta.example.com Identification information that uniquely identifies a SIP session CSeq:93809823 REFER The CSeq header field provides a method for identifying and ordering sessions, including a sequence number and a method to answer a response to a request The message must have the same CSeq as the request message (using the same method, and the same sequence number) to be paired Max-Forwards: 70 Identify the maximum number of path nodes that a message can pass through Accept-Contact:+g.3gpp.ps-video The Accept-Contact header field indicates the user's preference (such as requiring IMS video communication), and at this time, the network can make a matching judgment based on the information provided by the first user's request message and the various types of terminal capability information registered by the second user. Select the appropriate terminal type of the second user to continue the call, or reject the call when all the terminal capabilities of the second user are not satisfied Refer-To:<sip:sip:batlanta.example.com? Accept-Contact＝sip:bobsdesk.biloxi.example.com> The third-party target users transferred to, and give the specific contact address of the third party at the same time Contact:sip:aatlanta.example.com Identify the address information of the SIP terminal, and the terminal can receive the message through the SIP address Content-Type: application/sdp The Content-Type header field indicates the media type of the sent message body Content-Length:(...) The message length header gives the length of the message body SDP The SDP description of the media to be transferred is given in the message body

203. Detect the identity of the first user terminal, if the detection is passed, execute step 202, if not, execute step 210;

Wherein, after the second user terminal receives the service transfer request, security detection needs to be performed on the service transfer request, and the specific detection includes the following situations:

1. Identity detection: detecting whether the identity of the first user terminal sending the service transfer request is a legitimate user identity of the CSI service.

Wherein, the service transfer request sent by the first user terminal carries its own identification information, and the second user terminal judges whether the first user terminal is legal by matching the identification information.

2. Content detection: check the header field of the service transfer request, and judge whether the uniform resource identifier contained in the header field is consistent with the uniform resource identifier of the first user terminal. If they are consistent, further judge whether the contact address is consistent. If the contact address If not, the test passes.

204. Analyze the Uniform Resource Identifier (URI), if they are consistent, execute step 205, if not, execute step 210;

Wherein, comparing the source address header field in the transfer session request and the URI of the Refer-to header field, if the URIs of the two header fields are completely consistent, then perform the subsequent steps.

205. Analyze Accept-Contact, if it points to a different contact address, then execute step 206, if not, then execute step 210;

206. Extract the media information description information SDP, and obtain the type of media information to be transferred;

207. Obtain the type of media information supported by the destination device according to the media capability negotiated between the destination device and the sender;

Among them, the specific negotiation process is as follows:

1. The second user terminal sends an Invite message to the destination device, and the invite message carries parameters such as media type information and media resource reservation status;

2. After receiving the Invite message, the destination device judges its own media capabilities. If the destination device supports the media capabilities provided by the second user terminal, the destination device reserves media resources. After the media resource reservation is completed, the destination device returns a 200OK message, and the 200OK message carries media capability information and media resource reservation status to the second user terminal.

208. Determine whether the type of media information supported by the destination device includes the type of media information that needs to be transferred, if yes, execute step 209, if not, execute step 210;

209. Transfer the media information in the service to the destination device according to the address of the destination device;

210. Refuse to transfer the service, and feed back the reason for the rejection to the first user.

In the embodiment of the present invention, the service transfer request may be a video service transfer request, for example:

During the CSI call, the first user transfers the shared video content to the address space of the storage proxy server, and the user pre-registers on the video storage server with a specified account number and storage space size. At this point, step 202 may specifically be:

The CSI terminal of the first user initiates an IMS service transfer request, sends a REFER command to the second user terminal, and the Refer-To header field in the message is <sip:sip:batlanta.example.com? Accept-Contact=sip:bobstorage.biloxi.example.com>.

Wherein sip:sip:batlanta.example.com is the SIP URI of the first user, and Accept-Contact=sip:bobstorage.biloxi.example.com is the storage address of the storage proxy server of the first user in the IMS network.

Another example: during a CSI call, the video sharing content is transferred to the notebook of the same user, and the notebook is registered on the IMS network as the same SIP URI as that of the CSI terminal. At this time, step 202 may specifically be:

The CSI terminal of the first user initiates an IMS service transfer request, sends a REFER command to the second user terminal, and the Refer-To header field in the message is <sip:sip:batlanta.example.com? Accept-Contact=sip:bobdesktop.biloxi.example.com>.

Wherein sip:sip:batlanta.example.com is the SIP URI of the first user, and Accept-Contact=sip:bobdesktop.biloxi.example.com is a computer that the first user logs in with the same username in the IMS network.

It can be understood that, in actual use, the service transfer request may also be other media service transfer requests, as long as the user terminal supports the media service.

Through the embodiments of the present invention, the media information can be transferred to the destination device specified by the first user, thereby:

1. During a video call, the user may wish to store the video as a video file for repeated viewing in the future. Then, the service transfer method can be used to transfer the video to a certain server, and the server stores the video as a file format on behalf of the user. At the same time, it also overcomes the problem of limited mobile phone storage space, and the large storage space of the server is conducive to storing more video file content;

2. The screen of the mobile phone is usually very limited, so high-quality encoding format will not be used during the video negotiation stage; if the CSI video sharing is in progress, the video content can be shared to other playback devices, using high-code Streaming quality to enjoy content can improve user experience. In addition, even if the code stream is not renegotiated, the large screen is also conducive to improving the user experience.

Referring to Fig. 3, the second embodiment of the present invention is described below. In this embodiment, the business change is business maintenance:

301. The first user performs a CSI call with the second user;

302. When the user chooses to maintain the IMS service, the first user terminal sends an Update command to the second user terminal;

Wherein, the Update command carries an SDP message to the IMS network, and the SDP carries an attribute value "inactive" or "sendonly". At the same time, in order to prevent the second user terminal from performing additional operations on the voice service in the circuit domain after receiving the Update message, the restriction information on the operation domain is added to the CONTACT header field of the first user terminal, which is isCSIps in this embodiment , that is, restrict service operations only within the IMS domain.

303. After receiving the Update command, the second user terminal only maintains the IMS service according to the operation restriction information isCSIps in the CONTACT header field.

Among them, as the business expands, the operation restriction information can be expanded:

IsCSIps: represents the current business is limited to IMS business

IsCSIcsps: represents the current service including circuit domain and IMS domain

IsCSIcs: indicates that the current service is limited to the circuit domain

What is described in this embodiment is the maintenance of the IMS service. It can be understood that the service maintenance in the present invention is not limited to the IMS service, and may also be other similar services.
