Embodiment Construction

[0064] As used herein, the term "user equipment" (UE) is used for clarity. However, a UE may refer to one of various devices: the term "mobile device" is generally referred to herein and includes a mobile station, a terminal or node, a fixed or stable device, a station, a terminal or node, a human-type communication device , a machine-type communication (MTC) device, an Internet of Things (IoT) device, or other wireless end nodes communicating with a radio access node via wireless communication. Those skilled in the art will appreciate that a mobile device is a device designed to connect to a mobile network. This connection typically utilizes a wireless connection to an access node. Although mobile networks are designed to support mobility, mobile devices themselves do not have to be mobile. Some mobile devices, such as metering devices (eg, smart meters), may not be capable of mobility, but still utilize mobile networks.

Abstract

A method and device for connecting a user equipment (UE) to a wireless communication network, such as a 5th generation network. The network supports node-level tunneling. Node-level tunnels may be pre-configured prior to receiving a UE attach request. Tunnels can be shared by multiple UEs, flows or services. The policy function is connected to the network management function and performs tasks such as imposing constraints on node-level tunnels. The session management function pre-establishes node-level tunnels based on policy information from the policy function. The operation of network elements such as access network nodes and user plane functions handling UE attachment, session establishment and handling of mobile originated and mobile terminated traffic is described. Also described are methods and apparatus for packet transmission in which packets are processed according to an identified tunnel type. The tunnel type can be identified using a field in the tunnel encapsulation header.
