Problems solved by technology

This transition from idle mode to connected mode involves significant overhead on the client device in terms of signaling messages
Additionally, such transitions from idle mode to connected mode may cause the client device to remain awake for extended periods of time, and thus may increase the power consumption of the client device

Embodiment Construction

[0038] The detailed description, set forth below in conjunction with the accompanying figures, is intended as a description of various configurations and is not intended to represent the only configurations in which the concepts described herein may be practiced. The detailed description includes specific details to provide a thorough understanding of various concepts. It will be apparent, however, to one skilled in the art that these concepts may be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form in order to avoid obscuring the concepts.

[0039] In networks such as Long Term Evolution (LTE) networks, user plane security terminates at a network access node (eg, an evolved Node B, base station, or network access point). As such, a network access node should have a context for a client device (also referred to as an Internet of Things (IoT) device) for user plane data transmission. For example, ...

Abstract

In an aspect, a network supporting client devices includes one or more network nodes implementing network functions. Such network functions enable a client device to apply a security context to communications with the network when the client device is not in a connected mode. The client device obtains a user plane key shared with a user plane network function implemented at a first network node and / or a control plane key shared with a control plane network function implemented at a second network node. The client device protects a data packet with the user plane key or a control packet with the control plane key. The data packet includes first destination information indicating the first network node and the control packet includes second destination information indicating the second network node. The client device transmits the data packet or control packet.

Description

[0001] Cross References to Related Applications [0002] This application for patent claims the benefit of provisional application serial no. Priority, the entire contents of which are incorporated herein by reference. technical field [0003] In general, the present disclosure relates to communications, and more specifically, but not exclusively, to Internet of Things (IoT) network architectures. Background technique [0004] The ability of electronic devices to collect, process, and exchange data continues to grow. Additionally, network connectivity is being provided to an increasing number of these electronic devices. Such capabilities and features are enabling many electronic devices to evolve into Internet of Things (IoT) devices. As the number of these types of electronic devices continues to grow rapidly, networks may not have sufficient resources to support these electronic devices. [0005] For example, in an IoT environment, a network (eg, an LTE network) may n...
