METHOD FOR REDIRECTING A CALL TO AT LEAST ONE MESSAGE DEPOSIT SERVER

摘要

The present invention relates to a method for redirecting a call to at least one message deposit server chosen beforehand, when a call being set up is being transferred from a first terminal to a second terminal, the transfer being carried out by means of a first signaling message containing a value representative of a number of transfers of the call, referred to as the “forwarding field”, the method being such that it includes the steps of: assigning to the forwarding field of the first signaling message a first value greater than or equal to a threshold, the threshold corresponding to a value starting from which the transfer of a call is not allowed by the network; transmitting the first signaling message to the second terminal; and upon receiving a message indicating a failure to set up the call with the second terminal in response to the first signaling message, assigning to the forwarding field of a second signaling message a second value less than the threshold; and transmitting the second signaling message to the at least one chosen deposit server. The invention also relates to a server and a terminal comprising a device suitable for implementing the method according to the invention.

1. Method for redirecting a call to at least one message deposit server chosen beforehand, when a call being set up is being transferred from a first terminal to a second terminal, the transfer being carried out by means of a first signaling message containing a value representative of a number of transfers of the call, referred to as the “forwarding field”, the method being characterized in that it includes the following steps:
assigning to the forwarding field of the first signaling message a first value greater than or equal to a threshold, the threshold corresponding to a value starting from which the transfer of a call is not allowed by the network, transmitting the first signaling message to the second terminal, andupon receiving a message indicating a failure to set up the call with the second terminal in response to the first signaling message:
assigning to the forwarding field of a second signaling message a second value less than the threshold, and transmitting the second signaling message to the at least one chosen deposit server.
