Embodiment Construction

[0020] figure 1 An exemplary wireless communication network 10 is shown configured to operate as described herein. Wireless communication network 10 may comprise, for example, a Long Term Evolution (LTE) network; however, those skilled in the art will understand that the principles described herein may be used in other types of networks, including Wideband Code Division Multiple Access (WCDMA) networks, WiFi network and other Wireless Local Area Network (WLAN) and Worldwide Interoperability for Microwave Access (WiMAX) networks.

[0021] The wireless communication network 10 includes a radio access network (RAN) 15 including one or more base stations 20 . In LTE, the base station 20 is also called an evolved NodeB (eNodeB or ENB). Each base station 20 in the RAN 15 is connected to a serving gateway (SGW) 40 in the core network 35 and provides service to wireless devices 30 in the cell served by the base station 20 . The SGW 40 acts as a mobility anchor for the wireless devi...

Abstract

A lightweight communication protocol reduces overhead for small data transmissions from a wireless device to a base station over an uplink channel. The wireless device is preconfigured with a device identifier that is known to the base station. The preconfigured device identifier is associated with a static tunnel between the base station and a serving gateway. The wireless device transmits application data to the base station in a medium access control packet without using higher layer protocols. When the base station receives the medium access control packet, it maps the application data to the tunnel associated with the preconfigured device identifier.

Description

technical field [0001] Generally, the present invention relates to data transmission in wireless communication networks, and more particularly to methods and apparatus for low overhead data transmission in wireless communication networks for short data transmissions. Background technique [0002] Machine-to-machine (M2M) communication, also known as machine-type communication (MTC), is communication between devices without human intervention. Wireless communication networks are increasingly used for M2M communication. For example, wireless devices are now used in metering applications to report usage of utilities such as electricity and gas, in sensor networks to collect data from sensors, and in location fleet tracking applications. It is expected that in the near future, the demand for M2M communication will surpass normal person-to-person (H2H) communication. [0003] Currently deployed Long Term Evolution (LTE) networks and other broadband networks are designed to supp...
