Method for realizing call access and conference television terminal

Technical field

The embodiments of the present invention relate to, but are not limited to, the field of conference television conference processing, and specifically relate to a method for implementing call access and a conference television terminal.

Background technique

At present, during the conference of the conference TV terminal, if the terminal has repeatedly called another currently connected terminal or a multi-point control unit (MCU) conference in a different call mode, the conference television terminal still works. Repeatable call access, generally have the following four call modes:

1. Terminal A has called terminal B in H323IP mode, and then terminal A calls terminal B in SIP IP mode.

2. Terminal A has called terminal B in the H323 number mode, and then terminal A calls terminal B in SIP number mode (including TEL and URL mode);

3. Terminal A has called terminal B in H323IP mode, and then terminal A calls terminal B in H323 number mode.

4. Terminal A has called terminal B in the H323 number mode, and then terminal A calls terminal B in H323I P mode.

Preferred embodiment of the invention

Example 1

This embodiment provides a method for implementing call access, including:

Before any terminal in the conference television system initiates a call as the calling terminal, the calling terminal determines whether a call link has been established between the calling terminal and the called terminal according to the terminal information of the calling terminal and the called terminal;

When the calling terminal determines that a call link is not established between itself and the called terminal, the calling terminal initiates a link establishment to the called terminal, and requests the call access to send a call access request signaling.

The terminal information involved in this embodiment includes at least one or more of the following information:

Terminal name, terminal number, and terminal IP address.

Further, before the calling terminal initiates the call, if the calling terminal determines, according to the terminal information of the calling terminal and the called terminal, that the calling terminal has established a call link with the called terminal, for example, an H323 call link or an SIP call link. Then, the calling terminal no longer requests call access from the called terminal.

Based on the above method, after the called terminal receives the call access request signaling from the calling terminal, it can parse the terminal information such as the terminal name, the terminal number, and the terminal IP address of the calling terminal, and determine the called party according to the parsed terminal information. Whether the terminal has established a call link with the calling terminal, such as an H323 call link or an SIP call link. If already established, the called terminal returns a reject call access, such as a send call access reject signaling, to the calling terminal.

On the other hand, when the call link is not established between the called terminal and the calling terminal, the called terminal saves the H323 call link or SIP call link information corresponding to the call, and the called terminal responds to access the call signaling. Give the calling terminal.

Optionally, if the calling terminal receives the called terminal to agree to access the call message, the calling terminal may further save the H323 call link or SIP call link information of the call, and according to the terminal name of the called terminal, The terminal information such as the terminal number and the terminal IP address determines whether the calling terminal has established a media channel link with the called terminal. If there is already established, the calling terminal deletes the call link of the call, and the calling terminal sends a call hang up signaling to the called terminal, and the called terminal receives After the signaling, the call link corresponding to the call is deleted; if the media channel link is not established between the calling terminal and the called terminal, the calling terminal sends the media channel link setup request signaling to the called terminal.

Correspondingly, after receiving the media channel link setup request signaling, the called terminal parses the terminal information such as the terminal name, the terminal number, and the terminal IP address of the calling terminal, and the called terminal judges the called terminal according to the parsed terminal information. Whether the terminal has established a media channel link with the calling terminal. If it has been established, the called terminal deletes the call link corresponding to the call, and the called terminal sends call hang up signaling to the calling terminal, and after receiving the signaling, the calling terminal deletes the call link corresponding to the call. If the media channel link is not established between the called terminal and the calling terminal, the called terminal saves the media channel link information, and the called terminal sends the media channel link establishment consent signaling to the calling terminal. When the calling terminal establishes a media channel link, the calling terminal also stores the media channel link information of the call.

According to the above operation, the media channel can be mutually transmitted by using the media channel link between the calling terminal and the called terminal, thereby realizing normal communication of the conference television terminal.

The above description of avoiding the repeated call access technology of the connected conference television terminal will be described below with reference to the accompanying drawings.

1 is an intention of a terminal subsystem in an embodiment of the present invention. As shown in FIG. 1, a subsystem of a terminal includes a main control subsystem, a protocol subsystem, and a media subsystem.

The establishment of media, the destruction of media signaling, and the transmission of media streams.

2 is a flow chart of avoiding repeated call access of a connected conference television terminal in the embodiment of the present invention. As shown in FIG. 2, before the calling terminal initiates a call, the main control subsystem of the calling terminal is based on the called terminal. The call parameter checks whether the calling terminal has established an H323 call link or an SIP call link with the called terminal. If it has been established, the calling terminal's master control subsystem does not deliver the calling terminal's protocol subsystem. Calling the access request message, otherwise the calling control subsystem of the calling terminal sends a call request message to the protocol subsystem of the calling terminal, and the protocol subsystem of the calling terminal sends the H323 call link establishment or SIP call chain to the called terminal. The road establishes a message, and the reporting main control subsystem saves the call link information, and sends the call request signaling to the called terminal;

After receiving the call request signaling of the calling terminal, the protocol subsystem of the called terminal actively reports to the calling terminal. The master subsystem of the called terminal, the master subsystem of the called terminal verifies whether an H323 call link or an SIP call link has been established with the called terminal. If it has been established, the master subsystem of the called terminal sends a call access reject message to the protocol subsystem of the called terminal, and the protocol subsystem of the called terminal initiates call access reject signaling to the calling terminal. After receiving the message, the protocol subsystem of the terminal reports to the master control subsystem, and the master control subsystem deletes the call link corresponding to the call. Otherwise, the control subsystem of the called terminal saves the call link information, and sends a call permission message to the signaling subsystem of the called terminal, and the signaling subsystem of the called terminal receives the control subsystem of the called terminal. After the call access message is allowed, the caller is allowed to respond to the access call signaling;

The master subsystem of the calling terminal checks whether the media channel link of the calling terminal and the called terminal has been established. If it has been established, its master control subsystem deletes the call link corresponding to the call, and sends a call hang up message to its signaling subsystem, and its signaling subsystem initiates call hang up signaling to the called terminal. After receiving the hang up signaling of the calling terminal, the signaling subsystem of the calling terminal reports the call link deletion message to its main control subsystem, and the main control subsystem deletes the call link of the call, otherwise the call is saved. Media channel link, and initiating a media access request message to its media subsystem, the media subsystem initiates media access request signaling to the called terminal, and after the media subsystem of the called terminal receives the signaling, It is reported to its main control subsystem, and its main control subsystem judges whether the media channel link has been established based on the call information of the calling terminal and the called terminal. If it has been established, the calling subsystem of the called terminal deletes the call link corresponding to the call, and sends a call hang up message to its signaling subsystem, and its signaling subsystem sends a call hang to the calling terminal. After the message is received, the protocol subsystem of the calling terminal requests the master subsystem to delete the call link and the media channel link, and the master control subsystem deletes the call link and media channel corresponding to the call. Link, otherwise the master subsystem of the called terminal saves the media channel link corresponding to the call, and sends a media channel link establishment message to its media subsystem, and its media subsystem sends a consent to the calling terminal. The media channel link establishes response signaling, and reports that the main control subsystem saves the media channel link information, and the media subsystem of the calling terminal establishes a media channel link with the media subsystem of the called terminal, and sends each other. The media stream ensures the normal communication of the video conference.

The embodiment of the invention further provides a computer readable storage medium storing computer executable instructions for performing any of the above methods for implementing call access.
