Abstract

Systems and methods for handling a wireless device in a Configuration Management (CM)-Connected state with Radio Resource Control (RRC) Inactive state are provided. In some embodiments, a method for performing a mobility transfer from a Fifth Generation (5G) network to an Evolved Packet System (EPS) network includes a 5G network node: receiving, from an EPS network node, a context request for context associated with a User Equipment (UE); determining data forwarding information associated with the UE; and sending, to the EPS network node, a context response comprising context information associated with the UE and data forwarding information associated with the UE. In this way, packet losses will be minimized leading to improved end user performance.

Description

[0001] related application [0002] This application claims the benefit of Provisional Patent Application Serial No. 62 / 860,603 filed June 12, 2019, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0003] The present disclosure relates to the operation of wireless devices in an inactive state. Background technique [0004] The 3rd Generation Partnership Project (3GPP) has decided to introduce a new fifth-generation (5G) core network (5GC) and a new radio access technology called New Radio (NR) in the 5G system (5GS) ( RAT) both. However, the core network 5GC will also support other RATs besides NR, namely Evolved Universal Terrestrial Radio Access (E-UTRA). [0005] figure 1 Shows the network architecture of Evolved Packet System (EPS) and 5GS, showing the evolved Packet Core (EPC) including Long Term Evolution (LTE) nodes i.e. Enhanced or Evolved Node B (eNB) connected to Evolved Packet Core (EPC) Universal Terrestrial Rad...
