Donald John Sabourin, Jeffrey Stuart Dorin, Henry Joseph Happ III: Responsive routing control method and apparatus. Motorola, Sherry J Whitney, Frank J Bogacz, May 11, 1999: US05903545 (128 worldwide citation)

A method and apparatus for controlling routing within a communication system (10) modifies (258) routing tables (220, 230, 232, 234, 236) located within nodes (150) so that received data packets are not returned directly to their sending nodes. In response to detection (352) of a failed link, a node ...

Daniel Richard Tayloe, Johanna Alexandra Wild, James William Bishop Jr, William Neil Robinson: Method and apparatus for handing off calls between differing radio telecommunication networks. Motorola, Sherry J Whitney, October 20, 1998: US05826188 (111 worldwide citation)

A method for handing off calls between differing radio telecommunication networks recognizes (302) a desire for an inter-network hand-off. When a Subscriber Unit (120) (SU) identifies (304) a new network, a hand-off with the new network can be requested (320). When the SU (120) does not identify (30 ...
