Problems solved by technology

[0015] Although the above-mentioned prior art can realize the transfer of user-user information of ISDN terminals in the SIP network, the user-user information that can be transferred is limited to the defined narrowband ISDN user-user information, which cannot meet the requirements of the SIP network. Requirements for transferring extension numbers, game handles, and other various user-to-user application information newly emerging in the SIP network

Embodiment 1

[0097] Example 1: IP PBX uses the extension address identifier carried in the SIP INVITE session establishment request to realize automatic transfer application example

[0098] A SIP calling user in the public communication network calls an extension user inside an IP PBX connected to the SIP network, and the calling user sends a SIP INVITE session request message carrying extension address identification information in other forms except the extension number to the IP PBX Transfer to the switchboard, after receiving the message, the IP PBX can directly perform transfer control according to the extension address identifier carried in the INVITE message. Assume that the SIP URI of the IP PBX switching switchboard is abc@chinatelecom.com, and the extension address of the called user is identified in the form of SIP URI, specifically michael@abc.com. The following will introduce the details of carrying the extension address identification information in several INVITE messages. ...

[0120] Embodiment 2: An application example of carrying a game handle in a SIP INVITE session establishment request

[0121] In the field of IP electronic entertainment, when the initiator invites the participant to join a shared game that uses the SIP protocol for real-time session control and can perform real-time conversations, the initiator sends a SIP INVITE session request message carrying a shared game handle to the participant, and the participant receives After receiving the INVITE message, perform session control, and then join the shared game according to the shared game handle carried, which simplifies the cumbersome operation process in the background technology of first establishing a real-time call connection and then transferring the shared game handle by other means.

[0122] Figure 9 In the process of establishing a call session using the SIP protocol, the game handle information is transmitted between two communication users through SIP messages to realize ...

Embodiment 3

[0132] Embodiment 3: Application example of carrying ISDN UUI information in SIP message

[0133] In the application scenario where two ISDN terminals access the SIP network through an adaptation device such as an IAD, the access entity such as the IAD implements the adaptation and conversion of the user network signaling Q.931 signaling of the ISDN terminal to the SIP protocol. Figure 10 It is given that when the user-to-user signaling service (USER-TO-USER SIGNALLING, UUS for short) is applied between two ISDN terminals, the IAD uses SIP signaling to carry the user-to-user information (User-to-user signaling) in Q.931 signaling. UserInformation, referred to as UUI) to realize the example flow of ISDN UUI high-level application information transmission in the SIP network.

[0134] S1002, the ISDN calling terminal sends a Q.931Setup call setup request message carrying ISDN user-user information UUI_1 to the calling terminal IAD;

[0135] S1004, the calling terminal IAD maps ...

Abstract

The present invention relates to a method and a system which transfer as well as apply the user-user application message, comprising the following steps: step S202, the sending part sends the user-user application message which is schlepped in the conversational initial agreement message to the receiving part; and the step S204, the receiving part processes the corresponding processing according to the user-user application message which is schlepped in the conversational initial agreement message. The present invention is also provides an automatic switching method, a game sharing method which can real-timely process the conversation and a method which transfers the user-user application message by the signaling adapting entities. The present invention can flexibly describe varied data information and to realize the transmission as well as the processing of the newly increased specific user-user information.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method and system for transmitting user-user application information, an automatic transfer method, a game sharing method capable of real-time calls, and a method for transmitting information through signaling adaptation entities user - the method by which the user applies the information. Background technique [0002] Session Initiation Protocol (SIP for short) is one of the multimedia communication system framework protocols formulated by IETF (Internet Engineering Task Force, Internet Engineering Task Force). It is an application layer protocol used to establish, change or end multimedia sessions. RTP / RTCP, SDP, RTSP, DNS and other protocols work together to complete functions such as registration, location management, session establishment, and media negotiation of SIP terminals in the IP packet network. [0003] The SIP protocol has been widely recognized and favored...
