A method disclosed herein includes selecting, by the UE, a SNPN for registration, on the SNPN access mode being enabled. The method includes disabling, by the UE, the SNPN access mode, if the selected SNPN does not support at least one emergency service. The method includes enabling, by the UE, a Public Land Mobile Network (PLMN) selection mode to select a PLMN cell supporting the at least one emergency service, on the SNPN access mode being disabled. The method includes performing, by the UE, the at least one emergency service by camping on the selected PLMN cell. The method includes enabling, by the UE, the SNPN access mode for performing a SNPN selection procedure, on completion of the at least one emergency service.

Methods and systems for managing SNPN access mode

A method in a mobile station (MS) and an MS in a wireless communication network are provided. The method includes detecting an intersystem change from an S1 mode to one of an A/Gb mode and an Iu mode, detecting that a routing area update (RAU) has failed detecting that a successful generic location updating procedure has not been performed since the detected intersystem change, and triggering an MM specific procedure based on detecting that the RAU has failed and the successful generic location updating procedure has not been performed. The MM specific procedure corresponds to a location area update (LAU).

Technique for triggering mobility management specific procedure to avoid registration state mismatch between user equipment and network

A method for managing an extended Discontinuous Reception (eDRX) in a User Equipment (UE) including determining, by the UE, as to whether an eDRX enablement avoidance criterion is met, and causing, by the UE, to stop sending a request message, which is configured to enable the eDRX, to a network entity when the eDRX enablement avoidance criterion is met. The eDRX enablement avoidance criterion may include one of a data transmission pattern, a historic eDRX usage pattern, whether a configurable retry timer is deactivated, whether a number attempts made to enable the eDRX exceeds a threshold, whether a number of attempts made to enable and disable the eDRX exceeds a threshold, whether a request accept message including an indication that eDRX is not supported, is received from the network entity, or whether an indication of no eDRX support is received from the network entity may be provided.

Method and user equipment for managing extended discontinuous reception (eDRX)

A method in a mobile station (MS) and an MS in a wireless communication network are provided. The method includes detecting an intersystem change from an Smode to one of an A/Gb mode and an Iu mode, detecting that a routing area update (RAU) has failed detecting that a successful generic location updating procedure has not been performed since the detected intersystem change, and triggering an MM specific procedure based on detecting that the RAU has failed and the successful generic location updating procedure has not been performed. The MM specific procedure corresponds to a location area update (LAU).

A method and apparatus are provided for improved timing error detection.
