Embodiment Construction

[0022] Reference will now be made in detail to some of the present inventions, examples of which are illustrated in the accompanying drawings.

[0023] figure 1 An example 5G New Radio (NR) network 100 that supports conflict handling between PDU session establishment and PDU session release processes is described in accordance with novel aspects. The LTE / NR network 100 includes a data network 110 and an application server 111 that provides various services by communicating with a plurality of user equipments (UEs) including a UE 114 . exist figure 1 In the example of , UE 114 and its serving base station BS 115 are part of a radio access network RAN ​​120 . RAN 120 provides radio access to UE 114 through radio access technologies (RATs). Application server 111 communicates with UE 114 through User Plane Function (UPF) 116 and BS 115 . A Mobility Management Entity (MME) or Access and Mobility Management Function (AMF) 117 communicates with the BS 115 for access and mobili...

Abstract

A method of handling collision between PDU session establishment and PDU session release procedures is proposed. At UE side, a UE first initiates a PDU session establishment procedure to establish a PDU session having a PDU session ID. If UE receives a PDU session release command message on the same PSI, UE should ignore the PDU session release command message, and proceed with the PDU session establishment procedure. At NW side, a network entity initiates a PDU session release procedure to release a PDU session having a PDU session ID. If the network entity receives a PDU session establishment request message from UE on the same PDU session ID, the network entity should locally release the PDU session and proceed with the PDU session establishment procedure.

Description

[0001] cross reference [0002] This application claims priority under 35 U.S.C. §119 to U.S. Provisional Patent Application No. 62 / 742,325, filed October 6, 2018, and entitled "5G PDU Session Procedure Enhancements." The above application objects are hereby incorporated by reference. technical field [0003] The present invention relates generally to wireless communications. In particular, it relates to a conflict handling method between protocol data unit (PDU) session establishment and release processes in the next generation mobile communication system. Background technique [0004] Wireless communication networks have grown exponentially over the years. Long Term Evolution (LTE) systems offer peak data rates, low latency, improved system performance, and low operating costs due to simple network architecture. The LTE system, also known as the 4G system, also provides seamless integration with older wireless networks such as GSM, CDMA, and Universal Mobile Telecommun...
