Patent number: 11516696Abstract: A method for data exchange between a user equipment and a network node over a bearer service in a communication system. A virtual access network identifier identifies a connectionless bearer service on which a network service is mapped. A logical channel identifier identifies a connection oriented bearer service on which the network service is mapped. The data is exchanged between the user equipment and the network node over the connection oriented bearer service or over the connectionless bearer service depending on the amount of exchanged data and/or the data bit rate and/or the expiration of a timer.Type: GrantFiled: September 13, 2016Date of Patent: November 29, 2022Assignee: ALCATEL LUCENTInventors: Dietrich Zeller, Hajo-Erich Bakker
