Problems solved by technology

However, the method described in TS23.272 still requires the user equipment to establish a connected state with an associated high amount of signaling and is not suitable for widely used M2M services

Embodiment Construction

[0031] The above discusses specific problems that may arise from a large number of machine-to-machine (M2M) devices (MDs) communicating with a wireless cellular network, especially problems caused by relatively high signaling overhead. It is proposed here that by enabling MDs to communicate via base stations (where this term includes base stations of the LTE-enhanced UTRAN architecture and equivalents such as the corresponding base station controllers and radio network controls of 2G and 3G networks) without having to first establish a connected state, to alleviate these problems by exchanging user plane data with the core network. (The term "user plane data" refers to data generated at the application layer within a device or at a network or peer node, i.e. data that is not associated with network connections and services.) This means that a device can communicate without prior communication. Data is sent via the Radio Access Network (RAN) with the state established in the RA...

Abstract

A method of sending user plane data between a user device and a network entity within a packet core network via a radio access network. The method comprises 1) authenticating the user device to the network entity and establishing a Security Association between the user device and the network entity; 2) maintaining the user device in a connectionless state, such that no Security Association is established between the user device and the radio access networkand no data bearer is set up between the user device and said packet core network; 3) with the user device in said connectionless state, sending uplink and downlink user plane data between the user device and said network entity by including the data within signalling messages on the Non Access Stratum.

Description

technical field [0001] The present invention relates to a lightweight data transfer mechanism for transferring data between a client device and a core network via a radio access network. The invention is particularly, but not necessarily, applicable to machine-to-machine applications, where relatively small amounts of data are exchanged between client devices and the core network. Background technique [0002] In recent years, so-called machine-to-machine (M2M) applications using cellular network infrastructure are expected to grow rapidly. Such applications involve devices (hereinafter referred to as machine devices or MDs), such as sensors and actuators, that communicate with other devices or network servers, often without direct human operation. An example application may involve a household electricity meter configured to periodically send electricity consumption readings to a server owned by the supplying utility company. M2M applications are expected to substantially...
