Controlling and checking devices via the Session Initiation Protocol –a service for the IM subsystem

1 Idea of mobile service(s) provided by a mobile network operator

Idee: Johann Reitter, A-Berg im Attergau

The remote control and/or remote check of any kind of electric or electronic device via a mobileclient application, based on Internet Engineering Task Force's Session Initiation Protocol (SIP,Request For Comments 2543), is enabled. The information interchange between the client andthe device(s) takes place by either radio link(s), supplied by a mobile network operator at all, orvia radio link(s) established between the mobile client and the mobile network plus a fixed line(e.g. ISDN), installed between the mobile network and the electric or electronic device(s).Services of any kind can be offered by the network operator' s application server, placed in themobile network (IP based Multimedia domain), or by an external server, belonging to the electricor electronic device(s) (e.g. interconnected via an Ethernet LAN).

2 Abstract

The invention bases on the idea to control devices of any kind ( e.g. home appliances) by meansof IETF's SIP, because the IM subsystem is invented to drive a huge amount of different types ofservices (customized or non customized) and therefore operators are interested in purchasing thissystem. SIP has been chosen to be the application call control protocol for UMTS Rel.00 andRel4 respectively Rel5 mobile networks. But this protocol is not only capable of establishing,modifying and terminating (multimedia-) sessions. It can also be used to control and checknetworked appliances (note: not restricted to household appliances). At the moment, there aredifferent of them running in home communication systems, e.g. OSGi, UPnP , HA Vi, Salutation,nNI and VESA. Siemens AG and Ericsson are partners/members of OSGi and UPnP. Generalinformation about architectures (topologies), nodes, used protocols and SIP-methods for homeappliance control can be found in [1,2]. This paper informs the reader about a subset of possibleservices that can be realised by this idea. A listing of SIP messages and additional protocols,which are necessary to realize the idea, are shown. The possible topologies are explained by twofigures.

3 Different types of services, provided by this approach

Following listing is a subset of feasible services, provided by mobile network operators:


·   turning on and off the lights of the house or open and close the blinds of it via the mobilephone in order to keep thieves away

·   checking remotely things of personal interest by a video camera by transmitting its signals tothe user's mobile phone (e.g. looking into the refrigerator, if there is enough milk in it neededfor the baby or observing who is in front of the door)

·   checking environmental conditions, like temperature or humidity, remotely via the mo...
