Communication Protocol for Short Data Transmissions

摘要

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.

主权项

1. A method implemented by a base station in a wireless communication network for supporting small data transmissions by a wireless device, said method comprising:
associating a preconfigured device identifier for a wireless device with a tunnel between the base station and a serving gateway; receiving, at said base station, a medium access control packet from the wireless device over a wireless communication channel, said medium access control packet including application data transmitted by the wireless device for delivery to a destination device; mapping the preconfigured device identifier of the wireless device to the associated tunnel; and forwarding a data packet containing said application data to said serving gateway through said tunnel.
