Method and arrangement for call setup in telecommunications networks using signaling aided redialing
First Claim
1. 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.

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.

12. In a communication system a terminal A used by a subscriber pA to call a subscriber pB on a terminal B whereby said subscribers may have further terminals in the same or other networks, said terminal A comprising:
-
means for using in-band signaling over at least one public network for receiving from said terminal B and storing in said terminal A at least one terminal C address over which the called subscriber pB may be reached; means for storing in said terminal A said information and analyzing whether it is indicated to disconnect said first connection and redial; means for going on-hook and off-hook in said terminal A and for setting up at least one second connection between the subscribers pA and pB using as a destination said at least one terminal C address stored in said terminal A if it was indicated to disconnect said first connection to redial; and means for using said first connection as a traffic connection if not so indicated. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A telecommunication system comprising at least one network and a plurality of terminals whereby communication between a calling subscriber pA and a called subscriber pB includes the possibility of signaling a terminal C address from a called terminal B during a first preparatory call and whereby this preparatory call may be followed by a second traffic call to said terminal C address, the system comprising:
-
mobile radio terminals including; means for storing and later sending at least one terminal C address when receiving said preparatory call; and means for requesting and receiving at least one such a terminal C address and using it to originate said traffic call; transmission means including; means for transmission of user traffic; means for in-band transmission of said at least one terminal C address over at least a part of the at least one network; and a battery charging accessory connected to said terminal C including means for transmitting said at least one terminal C address to said mobile radio terminals when said mobile radio terminals are inserted into said battery charging accessory. - View Dependent Claims (20)
