- the connection step is a CONNECT step.
- the negotiation step conforms on the one hand to the ITLJ H 245 protocol for the establishment of a signaling channel and on the other hand to the ITLJ H 223 protocol for the establishment of a multiplexing for the signaling channel and video and audio logical channels.
- the local switch connected to the calling terminal LJEA will be called local switch VMSC (A) while the local switch connected to the terminal called LJEB will be noted local switch VMSC (B).
- the communication medium is open between terminals in both directions, i.e. so as to allow bi-directional transmission of messages, i.e. from the calling terminal to the terminal. called and the called terminal to the calling terminal.
- the calling terminal LJEA sends to the local switch VMSC (A) a SETUP message by which it initiates the call setup request.
- the local switch VMSC (A) sends on the one hand to the calling terminal UEA a message CALL PROC by which it acknowledges receipt of the terminal request calling and on the other hand to the GMSC gateway switch an IAM message by which it transmits the request of the calling terminal.
- the gateway switch GMSC sends the service node SN VRBT an IAM message by which it transmits the request from the calling terminal.
- the SN VRBT service node sends the VMSC (B) local exchange an IAM message by which it transmits the request from the calling terminal.
- the VMSC (B) local switch sends to the terminal called LJEB a SETUP message by which it transmits the request of the calling terminal.
- the terminal called LJEB sends to the local switch VMSC (B) a CALL CONF message by which it acknowledges the request from the calling terminal at the local switch VMSC (B) and an ALERTING message to the VMSC (B).
- LJEA calling terminal by which the terminal called LJEB signals that it has been alerted by the request of the calling terminal.
- the local switch VMSC (B) sends the service node SN VRBT an ACM message by which it transmits the alert of the called terminal.
- the SN VRBT service node sends the GMSC gateway switch an ACM message by which it transmits the alert of the called terminal.
- the gateway switch GMSC sends to the VMSC (A) local exchange an ACM message by which it transmits the alert of the called terminal.
- the local switch VMSC (A) sends the calling terminal LJEA an ALERTING message by which it transmits the alert of the called terminal.
- the step of negotiation of the logical channels between the terminals begins, which is noted by the line “negotiation start”.
- the end of this negotiation stage is noted by the line “negotiation end”.
- This negotiation takes place between the calling terminal LJEA and the service node SN VRBT.
- the service node SN VRBT provides the calling terminal with a video application, preferably a ringback with video function.
- the terminal called LJEB sends to the VMSC (B) on the one hand a CONNECT message by which it signals to the VMSC (B) local switch that the user of the terminal called UEB has dropped out. Reporting that the user of the LJEB terminal has gone off-hook will be noted subsequently signaling the reaction of the called user.
- the local switch VMSC (B) sends on the one hand to the terminal called LJEB a CONNECT ACK message by which it acknowledges the signaling of the reaction of the called user and on the other hand to the service node SN VRBT an ANM message by which it transmits the signaling of the reaction of the called user.
- the SN VRBT service node sends the GMSC gateway switch an ANM message by which it transmits the signaling of the response of the called user.
- the gateway switch GMSC sends the local switch VMSC (A) an ANM message by which it transmits the signaling of the response of the called user.
- the VMSC (A) local switch sends to the calling terminal LJEA a CONNECT message by which it transmits the signaling of the reaction of the called user.
- the calling terminal LJEA sends to the local switch VMSC (A) a CONNECT ACK message by which it acknowledges the signaling of the reaction of the called user.
- the beginning of the step of negotiation of the establishment of the logical channels between the calling terminal LJEA and the service node SN VRBT is between on the one hand the sending, by the terminal called LJEB of the ALERTING message, more precisely advantageously the sending by the service node SN VRBT of the ACM message having the function of transmitting the ALERTING message sent by the terminal called LJEB, and secondly the sending, by the terminal called LJEB , of the CONNECT message.
- the beginning of this negotiation step may be before or preferably after the reception by the calling terminal LJEA of the ALERTING message.
- the end of this negotiation stage denoted “negotiation end” can be located before and after sending, by the terminal called LJEB, the message CONNECT, according to the speed of reaction of the called user, that is to say say depending on when the user of the terminal called LJEB picks up.
- the logical channel establishment negotiation step begins immediately after receiving the message ALERTING.
- the logical channel establishment negotiation step begins, either just after the ACM message is sent, or when the VRBT SN service node detects that the calling terminal has started. stage of negotiation of the establishment of logical channels and for example tries to establish the multiplexing. If the called user picks up before the logical channel establishment negotiation step is completed, this logical channel establishment negotiation step continues normally as if the called user did not go off-hook.
- Another step of negotiation of the logical channels between the service node SN VRBT and the terminal called LJEB which is carried out in accordance with the protocols ITLJ H 245 and ITLJ H 223, incorporated here by reference, starts after sending, by the terminal called LJEB, from the CONNECT message.
- This video call setup method according to the invention also has the advantage of being compatible with a procedure of folding the video to the audio, in accordance with the SCLJDIF standard. This is interesting in the case where the called terminal only supports audio, unable to support the video.
- the LJEA expects firstly to have received the ALERTING message from the VMSC local switch (A) and secondly to have detected an attempt to start a logical channel negotiation from the service node SN VRBT which alone has the initiative to start the negotiation.
- the calling terminal LJEA as soon as it has received the ALERTING message from the VMSC local switch (A), directly starts the negotiation with the service node SN VRBT.
- the terminal called LJEB should not, meanwhile, try to start a negotiation of logical channels before sending the CONNECT message, since a call forwarding mode in case of absence answer is enabled.
- SN VRBT service node If by against, the terminal called UEB starts a negotiation of logical channels just after sending the message ALERTING, SN VRBT service node must not respond immediately to this solicitation from the terminal called LJEB, but rather wait until upon receipt of the ANM message, after sending the CONNECT message from the called LJEB terminal if it answers or the CONNECT message from another service node if the call forwarding arriving on the called LJEB terminal is activated.
