Claim:
1. A method for detecting a sleeping cell, comprising: monitoring an amount of traffic-related activities in a candidate cell in an observation period, the traffic-related activities comprising one or more activities that have a correlation with traffic in the candidate cell; calculating an accumulated amount based on the monitored amount of traffic-related activities, wherein the accumulated amount indicates an accumulation of one or more amounts of traffic-related activities monitored in an accumulation period, the accumulation period comprising at least one observation period; determining whether the accumulated amount exceeds a first threshold; in response to determining that the accumulated amount exceeds the first threshold, checking whether there is traffic in the candidate cell in the accumulation period; determining the candidate cell as a sleeping cell if there is no traffic; and resetting the accumulated amount if there is traffic.
