Abstract

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.

First claim

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, 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.

2 . Method according to claim 1 , characterized in that the message indicating a failure to set up the call in response to the first signaling message contains an indication relating to the cause of the error and in that the at least one deposit server to which the second signaling message is transmitted is chosen according to the cause of the error.

3 . Method according to claim 1 , characterized in that it additionally includes, when the message indicating the failure to set up the call with the second terminal contains an indication according to which the call is set up with a message deposit server, a step for transmitting a message for canceling the call intended for the message deposit server.

4 . Device 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 device being characterized in that it includes:
a counter suitable for assigning a first value greater than or equal to a threshold to the forwarding field of the first signaling message, the threshold corresponding to a value starting from which the transfer of a call is not allowed by the network,
a communication module suitable for transmitting the first signaling message to the second terminal, the counter and the communication module being operated upon receiving a message indicating a failure to set up the call with the second terminal in response to the first signaling message in order to:
assign a second value less than the predetermined threshold to a forwarding field of a second signaling message, and
transmit the second signaling message to the at least one chosen deposit server.

5 . Terminal characterized in that it includes a redirection device 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 device being characterized in that it includes:
a counter suitable for assigning a first value greater than or equal to a threshold to the forwarding field of the first signaling message, the threshold corresponding to a value starting from which the transfer of a call is not allowed by the network,
a communication module suitable for transmitting the first signaling message to the second terminal, the counter and the communication module being operated upon receiving a message indicating a failure to set up the call with the second terminal in response to the first signaling message in order to:
assign a second value less than the predetermined threshold to a forwarding field of a second signaling message, and
transmit the second signaling message to the at least one chosen deposit server.

6 . Server characterized in that it includes a redirection device 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 device being characterized in that it includes:
a counter suitable for assigning a first value greater than or equal to a threshold to the forwarding field of the first signaling message, the threshold corresponding to a value starting from which the transfer of a call is not allowed by the network,
a communication module suitable for transmitting the first signaling message to the second terminal, the counter and the communication module being operated upon receiving a message indicating a failure to set up the call with the second terminal in response to the first signaling message in order to:
assign a second value less than the predetermined threshold to a forwarding field of a second signaling message, and
transmit the second signaling message to the at least one chosen deposit server.

7 . Computer program including instructions for executing a redirection method when the program is executed by a processor, the 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, 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.

8 . Storage medium readable by a computer on which there is recorded a computer program comprising instructions for executing a redirection method, the 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, 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 depo
