INFORMATION AND COMMUNICATION TECHNOLOGIES AIMING AT THE REDUCTION OF THEIR OWN ENERGY USE ## Abstract There is disclosed an apparatus. The apparatus comprises means for performing: when the apparatus is in an INACTIVE radio resource control state, transitioning from the INACTIVE radio resource control state to an IDLE radio resource control state, when it is determined by the apparatus that the apparatus has performed a radio access network notification area update a number of times that is equal to or greater than a configured number, N. ## Claims ### Claim 1 An apparatus comprising: at least one processor; and at least one memory including computer program code; the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to: when the apparatus is in an INACTIVE radio resource control state, transition from the INACTIVE radio resource control state to an IDLE radio resource control state, when it is determined by the apparatus that the apparatus has performed a radio access network notification area update a number of times that is equal to or greater than a configured number, N. ### Claim 2 (depends on 1) The apparatus of claim 1, wherein the computer program code and the at least one processor are configured to cause the apparatus to operate a timer to determine whether the apparatus has performed a radio access network notification area update a number of times that is equal to or greater than the configured number, N, within a time window. ### Claim 3 (depends on 1) The apparatus of claim 1, wherein each radio access network notification area update is due to one or more of: movement of the apparatus; environmental factors; cell movement. ### Claim 4 (depends on 1) The apparatus of claim 1, wherein the computer program code and the at least one processor are further configured to cause the apparatus to change from the INACTIVE radio resource control state to the IDLE radio resource control state instead of initiating a radio access network notification area update procedure with a network. ### Claim 5 (depends on 1) The apparatus of claim 1, wherein the computer program code and the at least one processor are further configured to cause the apparatus to determine a number of traffic events, x, experienced by the apparatus over a time window, y. ### Claim 6 (depends on 5) The apparatus of claim 5, wherein the computer program code and the at least one processor are further configured to cause the apparatus to transition from the INACTIVE radio resource control state to the IDLE radio resource control state, when it is determined by the apparatus that the apparatus has performed a radio access network notification area update a number of times that is equal to or greater than the configured number, N, and the number of traffic events is less than or equal to x. ### Claim 7 (depends on 1) The apparatus of claim 1, wherein the configured number, N, takes in to account information of one or more of: movement of the apparatus; downlink traffic of the apparatus; uplink traffic of the apparatus; a number of other apparatus in the INACTIVE state; cell movement. ### Claim 8 (depends on 1) The apparatus according to claim 1, wherein N is configured by the apparatus. ### Claim 9 (depends on 1) The apparatus according to claim 1, wherein N is network configured. ### Claim 10 (depends on 1) The apparatus of claim 1, wherein the computer program code and the at least one processor are further configured to cause the apparatus to, once in the IDLE state, listen for or detect network paging messages according to an IDLE configuration, unless the apparatus had an apparatus-specific paging configuration in the INACTIVE state, in which case the apparatus is configured to continue using the apparatus-specific paging configuration when in the IDLE state. ### Claim 11 (depends on 1) The apparatus of claim 1, wherein the computer program code and the at least one processor are further configured to cause the apparatus to simultaneously support INACTIVE and IDLE paging. ### Claim 12 (depends on 11) The apparatus of claim 11, wherein the computer program code and the at least one processor are further configured to cause the apparatus to support the INACTIVE and IDLE paging during a time period set by a timer, the time period based on radio access network notification area update periodicity and a last periodic radio access network notification area update that was made. ### Claim at position 13 13-14. (canceled) ### Claim 15 An apparatus comprising: at least one processor; and at least one memory including computer program code; the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to: send a configuration to a user equipment, the configuration comprising a number, N, which specifies how many times the user equipment when in an INACTIVE radio resource control state may perform a radio access network notification area update before transitioning from the INACTIVE radio resource control state to an IDLE radio resource control state. ### Claim 16 (depends on 15) The apparatus according to claim 15, wherein each radio access network notification area update is due to one or more of: movement of the user equipment; environmental factors; cell movement. ### Claim 17 (depends on 15) The apparatus of claim 15, wherein the computer program code and the at least one processor are further configured to cause the apparatus to specify to the user equipment a number of traffic events, x, and a time window, y, such that the configuration sent to the user equipment specifies that the user equipment may transition from the INACTIVE radio resource control state to the IDLE radio resource control state when the user equipment has performed a radio access network notification area update a number of times that is equal to or greater than N and the number of traffic events is less than or equal to x. ### Claim 18 (depends on 15) The apparatus of claim 15, wherein the configured number, N, takes in to account information of one or more of: movement of the user equipment; downlink traffic of the user equipment; uplink traffic of the user equipment; a number of other user equipment in the INACTIVE state; cell movement. ### Claim 19 (depends on 15) The apparatus of claim 15, wherein the apparatus comprises a network apparatus. ### Claim 20 (depends on 15) The apparatus of claim 15, wherein the apparatus comprises a base station and the configuration is sent to the user equipment as part of radio resource control and/or system information block signalling. ### Claim at position 20 21-25.
