Title: Repeater backup arrangement for securing operation of a telecommunications network in a cellular radio system
Inventor: KOPONEN PEKKA
IPC: H04B1/74
Filed: 1994-08-05
Abstract: In a cellular radio system in which the base stations 1 not only provide radio communications with units in their coverage area, but are also connected to one another and to a base station controller (2, Fig. 1) by cables 3 and serve as repeaters for the signals on the cables 3, failure of a base station 1 (eg. due to a mains power disturbance) is sensed by a control unit 6 which then enables a repeater 5 connected to the cable 3 in parallel with the base station 1. Thus, such a breakdown only affects the radio cell of the failed base station 1, and not the cabled telecommunications network. The repeater 5 has a backup battery so that it can operate during a mains disturbance. The base station 1 may incorporate switches 4, 7 by means of which the control unit 6 can totally disconnect the failed base station from the network 3. <IMAGE>

Title: Automated routing of messages over a network
Inventor: PITTENGER PAUL M
IPC: G06Q20/20
Filed: 1996-06-07
Abstract: A system for processing credit card transactions is disclosed. Transaction data to be processed is sent by point of system terminal to a terminal node connected to a sophisticated communications network. The terminal node uses routing data contained in the transaction data to establish a connection to a verification service host. The connection is established while the terminal node concurrently continues to receive and then validate the transaction data. Overall transaction processing time is reduced because the network connection needed for verification of the transaction data is established while, rather than after, transaction data is received and validated.
