Patent ID: 8428589

Claim:
A method for user equipment (UE) context setup in an eNodeB for a UE subscriber in an infrastructure network, the network comprising at least one eNodeB providing radio access for the UE and a mobility management entity (MME) connected to the eNodeB, the eNodeB comprising an inactivity timer releasing the UE context being setup in the eNodeB after a defined time period, comprising: receiving at the eNodeB a setup request transmitted from the UE, wherein the eNodeB, in response to said setup request, sends an initial UE message to the MME to initiate the UE context setup, the initial UE message identifying the UE sending the setup request, and the MME is configured such that, in response to said initial UE message, the MME sends an initial UE context setup request to the eNodeB; receiving at the eNodeB the initial UE context setup request; and responding, by the eNodeB, to the MME with an initial context response complete, wherein the initial UE context setup request includes timer setup information for said UE, and the eNodeB uses the timer setup information to define said time period; wherein the timer setup information is defined by the MME on the basis of IMEISV International Mobile Equipment Identity Software Version (IMEISV) or International Mobile Subscriber Identity (IMSI); wherein the eNodeB increase the time period of the inactivity timer when the number of handovers for the UE are reduced or the number of service requests from the UE are increased; and wherein the eNodeB reduces said time period of the inactivity timer when the number of handovers for the UE are increased or the number of service requests from the UE are reduced.
