Abstract
Abstract In a communication system a method and means for signaling-supported-redialing whereby a traffic connection between a calling and a called subscriber is set up by first making a preparatory data-only call in order to get, via machine-readable inband signaling, alternative telephone numbers to terminals available to the called subscriber and after that going on-hook to terminate the preparatory data-only call and going off-hook again to make a new call for the actual traffic, redialing one of the numbers just received from the called subscriber.

Total Claims: 23
Claim 1
Independent Claim
185 words
In a communication system a method for setting up at least one traffic connection between a subscriber pA calling from a terminal A and a subscriber pB called on a terminal B whereby said subscriber pB may have further terminals in the same or other networks, comprising the following steps: storing in said terminal B at least one terminal address C over which the called subscriber pB may be reached; calling said terminal B from said terminal A whereby terminal B goes off-hook unconditionally establishing a first connection between terminals A and B; signaling from said terminal B to said terminal A over said first connection information including at least one terminal address C; storing in said terminal A said information and analysing whether it is indicated to disconnect said first connection and redial; if indicated, going on-hook and off-hook in said terminal A and setting up at least one second connection between the subscribers pA and pB using as a destination said at least one terminal address C stored in said terminal A; if not indicated, using said first connection as a traffic connection.

Claim 9
Dependent Claim
17 words
The method of claim 3, wherein the terminal B is a terminal capable of data messaging only.
Claim 10
Independent Claim
30 words
The method of claims 1, wherein the step of setting up at least one second connection is performed when initially setting up a call between the subscribers pA and pB.
Claim 11
Independent Claim
28 words
The method of claims 1, wherein the step of setting up at least one second connection is performed during an ongoing call between the subscribers pA and pB.
Claim 12
Independent Claim
46 words
The method of claims 1, wherein the step of signaling is performed over a first connection between the subscribers pA and pB via a service node and wherein the step of setting up creates a second connection bypassing said service node and disconnects said first connection.
