ENABLING IP-COMMUNICATION WITH A MACHINE TO MACHINE UNIT

摘要

A Proxy Unit is connectable to a communication network and is arranged to enable IP Communication with a Machine to Machine Unit. The Proxy Unit receives and stores in a session data base a first IP address a device identifier and a unique ID of the Machine to Machine Unit. The Proxy Unit then receives from a Machine to Machine application a message destined to the Machine to Machine Unit and comprising the unique ID of the Machine to Machine Unit. The Proxy Unit finds the associated device identifier and the first IP address in the session data base, using the received unique ID. If the Proxy Unit detects no active session for the Machine to Machine Unit, it uses the device identifier to send a wake up message to the Machine to Machine Unit for enabling IP communication.
