Abstract:
1. A self-aware dynamic authorization method for closed femtocell environments, comprising: executing initialization of a dynamic authorization table using a dynamic authorization module configured by a hardware processor, for setting an authorization record in said dynamic authorization table for each of at least an admissible user of a closed femtocell, said authorization record having a Mobile Station International Subscriber Directory Number (MSISDN) field, an International Mobile Subscriber Identity (IMSI) field, a start time field and a duration field; executing an initial phase for learning data using the dynamic authorization module, learning to obtain an International Mobile Subscriber Identity (IMSI) or a Mobile Station International Subscriber Directory Number (MSISDN) of each non-authorized user for adding or updating a corresponding authorization record with said IMSI or said MSISDN learned by said closed femtocell through service experiences; executing a reweighting phase using the dynamic authorization module, for reweighting each non-authorized user by dynamically adjusting a duration of access to said closed femtocell for each non-authorized user, said duration of access being recorded in said duration field in the corresponding authorization record; and executing an ageing phase using the dynamic authorization module, for deleting the authorization record with an expired duration of access or an oldest start time from said dynamic authorization table; wherein in each said authorization record, said MSISDN field and said IMSI field are key fields, said start time field records a start time when said closed femtocell most recently obtains or serves a corresponding user, and said duration field records the duration of access authorized to the corresponding user.
