A method and apparatus for re-establishing an interrupted data packet call on a channel between two transceiving devices in a telecommunications system. In an embodiment of the invention, when packet data has not been sent or received in the call for a predetermined time period, the call is released and call configuration information is saved in at least one of the transceiving devices. If it is then necessary to transmit further packet data for the call, either one of the transceiving devices may initiate, within a predetermined time period, the sending of a call re-establishment message to re-establish the call. The call re-establishment message includes only necessary information to re-establish the call. Information that is saved upon call release is not sent in the re-establishment message. Information in the re-establishment message is used to retrieve the call configuration information that was saved upon call release. The call is then re-established using the information in the re-establishment message and the retrieved information. <IMAGE> |
