Dual System Cellular Cordless Radiotelephone Apparatus With Sub-Data Channel Timing Monitor

View page
US Patent:
54426804, Aug 15, 1995
Filed:
Aug 25, 1994
Appl. No.:
8/296263
Inventors:
Michael J. Schellinger - Vernon Hills IL
Stefan G. Littig - Arlington Heights IL
Assignee:
Motorola, Inc. - Schaumburg IL
International Classification:
H04Q 738
US Classification:
379 58
Abstract:
A cellular cordless telephone may receive cellular telephone calls via a cellular telephone system and receive telephone calls on a system having a limited radio coverage area. To reduce the amount of time spent in monitoring the sub-data channel of the limited coverage area system, a timing signal is generated which represents the period of time spent monitoring the radio channel. During the monitoring, a predetermined number of data words transmitted on the limited radio coverage area radio channel system are received. When a first received data word is detected, an allowed monitoring time value is adjusted to be the sum of the value of the timing signal and the product of a determined number of received words to be detected and the time required for each word. This adjusted value of the monitoring time value is compared to the value of the timing signal and when the adjusted monitoring time value equals or exceeds the timing signal value, the monitoring of the radio channel ceases.

Universal Radio With Adaptive Memory

US Patent:
55242766, Jun 4, 1996
Filed:
Nov 26, 1993
Appl. No.:
8/158077
Inventors:
Stefan G. Littig - Arlington Heights IL
Pamela A. Dillard - Lake Zurich IL
Assignee:
Motorola - Schaumburg IL
International Classification:
H04B 138
H04Q 732
US Classification:
455 331
Abstract:
A universal radio (401) having an adaptive memory is used by field service centers to give a radio user immediate access to a radio system regardless of the model type of the user's defective radio (403) while the defective radio (403) is being repaired. An information set in the defective radio's memory is transferred into the universal radio's memory for subsequent independent operation of the universal radio in the radio system.
