Abstract:
The invention concerns a method for invoking at least one service application server (AS) during a communication between an originating user agent (O_UA) and end user agent (T_UA). It consists at least in opening (A) two separate dialogues, between a service selecting function (SIF) and, respectively, the originating agent (O_UA) and the end agent (T_UA). The function (SIF) is substituted to the user agent (T_UA) in its dialogue with the user agent (O_UA) and to the user agent (O_UA) in its dialogue with the user agent (T_UA). The messages from the user agents during the two opened dialogues are stored (B) and at least one service conditional triggering criterion on the two dialogues is verified (C). If the triggering criterion is verified, at least part of the messages is restored (D) to the server so as to trigger the invocation thereof. The invention is useful for invoking application servers in a SIP network.
Abstract:
Method of routing in a telecommunications network an SIP message intended to be routed through intermediate entities constituting nodes of a signaling path. According to the invention, said method comprises a step of bypassing an intermediate entity able to be bypassed if unavailable. Application to the IMS architecture.
Abstract:
A method and apparatus are provided for processing an item of information indicative of a desire for involvement in at least one application session, established according to the SIP protocol, in progress for a user of a telecommunications network. The at least one session is controlled by a first terminal of the user. The method is implemented by the first controller terminal, and includes receiving a notification of an event relating to the user, which includes at least one item of information indicative of a level of involvement desired by a second terminal of the user, and making a decision relating to the desired level of involvement. In the case of a positive decision, an involvement command is transmitted relating to the level of involvement desired by the second terminal to the telecommunications network.
