Title:
METHOD FOR REDUCING NAS SIGNALING OF LCS AND LPP PROCEDURES
Document Type and Number:
WIPO Patent Application WO/2021/000887
Kind Code:
A1
Abstract:
The present invention relates to a method for reducing NAS signaling of LPP and LCS procedures initiated by UE in an EMM idle mode and an EMM registration state. The method disclosed relates to various methods for encapsulating an LPP/LCS message into a control plane service request. This makes it possible for the UE and eNB to transmit the LPP/LCS message during an RRC connection establishment procedure, which can be considered as an extension to control plane EPS CIoT optimization.
