TD S2 160526 23.060 CR1995R1 (Rel 13, 'F'): Inactivity timer for eDRX. (Source: Alcatel-Lucent, Alcatel-Lucent Shanghai Bell). (Revision of TD S2 160189).
Abstract: Summary of change: For UTRAN For an UE for which eDRX has been enabled, if the SGSN is aware that some signalling or data is pending in the network for that UE (e.g. pending MT SMS at the SMS Service Center or an application has subscribed to UE reachability), the SGSN should include a 'minimum user inactivity time' in the next RAB Establishment Request message towards UTRAN. The UTRAN shall not release the RRC connection due to user inactivity before expiration of the 'minimum user inactivity time' (the RRC connection may be released before that expiration for other causes such as Radio Connection With UE Lost). For the cases when the UE is handed over to another eNB shortly after the UE-CN connectivity is established, the 'minimum user inactvity time' should also be sent in the Handover Request message. With this solution, the user inactivity period may be extended only for the scenarios where there is pending MT signalling or data for a UE. In all other scenarios (e.g. MO signalling w/o pending MT signalling), there won't be any change, i.e. the existing user inactivity timer is used. For GERAN For GERAN, when extended idle mode DRX is enabled for a MS, the SGSN shall use the TS 24.008 READY Time as 'minimum user inactivity timer'. If PFC procedures are used, the SGSN shall use the TS 48.018 Packet Flow Time (PFT) as 'minimum user inactivity timer'.
Parallel discussion: Should be opened only if some offline agreement can be made on this issue.
