METHODS AND APPARATUSES FOR SHORT DATA TRANSMISSION

摘要

A lightweight communication protocol reduces overhead for small data transmissions from a wireless device (30) to a base station (20) over an uplink channel. The wireless device (30) is preconfigured with a device identifier that is known to the base station (20). The preconfigured device identifier is associated with a static tunnel between the base station (20) and a serving gateway. The wireless device (30) transmits application data to the base station (20) in a medium access control packet without using higher layer protocols. When the base station (20) receives the medium access control packet, it maps the application data to the tunnel associated with the preconfigured device identifier.
