Wireless communication system, its base station and mobile station, communication synchronization management method and timer control program therefor
Abstract:
The present invention provides a wireless communication system which can reduce the probability that a latency before data transmission increases when a mobile station that is actually in sync is judged to be out of sync based on a timeout of the timer used for judging whether a mobile station is in a deemed in-sync state or in a deemed out-of-sync state. A base station of a wireless communication system which performs communication between a mobile station and the base station, includes a timer unit which sets a period for judging whether an uplink signal from the mobile station is synchronized; and a timer control unit which is capable of determining the period for each of mobile stations and notifies the period to each of the mobile station upon RRC establishment or RRC re-establishment.
