US 2019/0098516 A1 · TECHNIQUE FOR TRIGGERING MOBILITY MANAGEMENT SPECIFIC PROCEDURE TO AVOID REGISTRATION STATE MISMATCH BETWEEN USER EQUIPMENT AND NETWORK

Abstract

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).

Dependent claims

A method in a mobile station (MS), the method comprising:

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 since the detected intersystem change;
detecting that a successful generic location updating procedure has not been performed since the detected intersystem change;
and
performing a mobility management (MM) specific procedure when the RAU has failed and the successful generic location updating procedure has not been performed since the detected intersystem change,
wherein the MM specific procedure corresponds to a location area update (LAU).
