Problems solved by technology

If the mapped 5GSM parameter is removed, after inter-system change from A / Gb mode or Iu mode back to S1 mode, PDN connection is not possible since PSI is only provided in PDN connection request message Support intercommunication with 5GS
Additionally, it is undefined whether to enable transfer of PDN connections from Packet Data Protocol (PDP) context (without mapped 5GSM parameters) to support interworking with 5GS

Embodiment Construction

[0024] Reference will now be made in detail to some embodiments of the invention, examples of which are illustrated in the accompanying drawings.

[0025] figure 1 Exemplary 5G / 4G / 3G / 2G network 100 and PDN connections supporting inter-system change to 5GS are illustrated according to a novel aspect. 5G NR network 100 may include UE 101, base station gNB / eNB 102, access and mobility management function (Access and Mobility Management Function, AMF) / session management function (Session Management Function, SMF) 103 and 5G core network (5G Core network , 5GC) / 4G core network EPC 104. exist figure 1 In the example of , UE 101 and its serving base station gNB 102 belong to a part of radio access network (Radio Access Network, RAN) 120 . In the access stratum (Access Stratum, AS), the RAN 120 can provide radio access for the UE 101 via a radio access technology (Radio Access Technology, RAT). In the Non-Access Stratum (NAS), the AMF / SMF 103 can communicate with the gNB 102 and...

Abstract

Disclosed is a method for handling PDN connection which supports mutual connection with 5GS. In the first novel aspect, when changing from S1(4G, EPS) mode to A / Gb(2G) mode or Iu(3G, UMTS) mode system, UE and network both can store the mapped 5GSM parameters of corresponding PDU conversation. In the second novel aspect, the PDN connection can be started to support connection with the 5GS. In addition, the UE is allowed to employ the bearing resource modification process to allocate and indicate PSI, or the mapped 5GSM parameters can be provided and modified in the 2G / 3G system.

Description

[0001] cross reference [0002] This application claims priority under 35 U.S.C.§119 to U.S. Provisional Application 62 / 843,642, filed May 6, 2019, entitled "PDNconnection supports interworking to 5GS", the contents of which are incorporated herein by reference . technical field [0003] The present invention relates to wireless communications, and in particular to establishing and modifying support for fifth generation (5 th Generation, 5G) system (5G System, 5GS) interworking (Packet DataNetwork, PDN) connection method. Background technique [0004] Wireless communication networks have grown rapidly in recent years. Due to the simplified network architecture, the Long-Term Evolution (LTE) system can provide high peak data rate, low latency (latency), higher system capacity and low operation cost. The LTE system (also known as the fourth generation (4 th Generation, 4G) system) can also provide seamless convergence with legacy wireless networks, such as Global System ...
