Abstract

A method implemented on a user device (UE) that includes servicing a Personal Internet of Things (IoT) network (PIN) element (PINE) associated with a PIN to provide a direct connection between the PINE and the UE acting as a gateway-enabled PINE (PEGC), receiving Internet Protocol (IP) packets at the UE via a core network (CN), and routing the IP packets to the PINE, taking into account the headers of the IP packets.

Description

Cross-reference of related applications This application claims priority to (1) U.S. Provisional Patent Application No. 63/493,723 entitled “Method of Handling Communication Configuration for Personal IoT Network,” filed on 31 March 2023, and (2) U.S. Provisional Patent Application No. 63/495,074 entitled “Method of Handling Communication Configuration for Personal IoT Network in 5G System,” filed on 7 April 2023, and claims the benefit of the filing date thereof. The entire contents of those provisional applications are expressly incorporated herein by reference. This disclosure generally relates to methods, devices, and articles in wireless communication systems, such as 3GPP® communication systems, and more particularly to processing Personal Internet of Things (IoT) network (PIN) traffic. This background information is provided for the purpose of providing a general overview of the background to this disclosure. Within the scope of the background information section, the work of the inventors named herein, as well as aspects of this specification that may not meet the requirements of prior art at the time of filing, are not expressly or implicitly recognized as prior art to this disclosure. Generally, within a personal IoT network (PIN), a PIN element with gateway functionality (PEGC) can provide 5G connectivity to PIN elements (PINEs) connected to the PEGC (i.e., "behind the PEGC"). The PEGC enables PINEs within the same PIN to communicate with each other across the PEGC and different PEGCs via the 5G core network (CN). A PIN may include at least one PEGC. A PEGC may support one or more PINs. A PEGC is a PIN member. A PINE may be a 3GPP user device (UE) (e.g., using sidelink communication via the PC5 interface) or a non-3GPP device connected to a PEGC (e.g., using Wi-Fi, Bluetooth). The non-3GPP device may support IP-based connectivity (e.g., Wi-Fi, Bluetooth Low Energy) or non-IP-based connectivity (e.g., Bluetooth). However, direct communication between IP-based and non-IP-based devices is only possible by routing PIN traffic locally across PEGCs. While multiple PEGCs may exist for a single PIN, it is unclear how devices can implement inter-PIN communication across different PEGCs via 5G CNs. In a scenario where a Public Land Mobile Network (PLMN) has multiple PINs and a PIN has multiple PEGCs, there is no clear mechanism in either the PEGC or the CN to identify the PIN and the PINE connected to the PEGC for the purpose of routing PIN traffic to the destination PINE connected to the PEGC. Furthermore, there is no clear mechanism to coordinate PIN communication configuration information among the various network functions (NFs) of the PEGC and CN, and/or functions provided by third-party entities.
