Title: Radio channel interference monitor system in personal handy phone system
Inventor: TAKAHASHI NAOTO
IPC: H04W24/06
Filed: 1995-08-22
Abstract: PROBLEM TO BE SOLVED: To allow a base station to make autonomous interference monitor and start notice of interference monitor to a peripheral base station by using access information (traffic information) from a mobile set to the base station as an opportunity of interference monitor. SOLUTION: Access information (traffic information) sent from a mobile set MT to a base station BS is used for an opportunity of interference monitor start and the information is stored in a traffic information storage section 2. A base station control section 7 starts the timer of a timer control section 3 and retrieves the content of the traffic information storage section 2 for each prescribed time based on a timing signal and discriminates the change in incoming access information from the mobile set MT. When the change in the information (such as no access for a prescribed time) is detected, the base station BS starts interference monitor autonomously. When the interference monitor is started, the interference monitor is reported to a peripheral base station. Thus, simultaneous occurrence of interference monitor is prevented between peripheral base stations.
