Guardian Angel Ambulance-to-Hospital Mobile IPv6 Multi Access Network IPv6 Wireless Initiative Ambulance UKT-Hospital Live- Acute Consultation Vital SignStreams LiveVideo- LIVE-Telemanagement Streams Ambulance Experts in the Guardian-Angel center in the hospital give advice to the remote team Ambulance crew with problems caring for a patient in an emergency Medical background Conception Perspective Errors are a leading cause of death in patients. In emergency situations help is needed immediately when necessary. Often there is a lack of permanently available experienced medical staff. The Guardian-Angel-System closes this gap in the medical field. Whenever a medical team cannot solve a medical emergency problem, they are able to contact the Guardian-Angel experts. Therefor they use a one-button activation of all necessary systems and transmissions and wear wireless headsets for undisturbed communication. When the medical, legal and technical problems of the Guardian-AngelSystem are solved, it could be established as a routine back-up and emergency care system in many fields of modern medicine: intensive care units, operating rooms, emergency departments and of course mobile in ambulance cars. The Guardian Angel medical applications require an ability to seamlessly roam between different types of access networks – whatever is the best available in a certain location. “UKT-Hospital” GPRS / UMTS SGSN Ericsson Router (HA) GGSN GPRS / UMTS Ambulance WLAN WLAN Internet WLAN WLAN Universität Tübingen Dept. of Anesthesiology Patient Safety and Simulation [email protected] Universität Stuttgart Rechenzentrum ‘RUS’ Communication Systems [email protected] Access router Ericsson Research has implemented this functionality at the IP/network layer within a prototype Multiaccess Mobile IPv6 stack. Medical applications within a Guardian Angel Ambulance can always stay best-connected with the hospital. OY L M ERICSSON AB NOMADICLAB PL 58 02131 ESPOO FINLAND [email protected] In the Multiaccess network IP traffic can be dynamically transferred from one network interface to another. A video stream on the patient can be transferred from GPRS to WLAN, to achieve higher bandwidth and picture quality. ERICSSON TELEBIT A/S Skanderborgvej 232 8260 Viby J DENMARK [email protected] IST 2000 - 25153 DNS In the future different IP flows can also use separate interfaces simultaneously. For example, sufficient reliability might not be available in a WLAN network, therefore vital data transmissions could simultaneously use a GPRS or UMTS interface.

Users can control the placement of IP traffic in different interfaces based on application requirements and information on the accesses. The presented Multiaccess network is transparent to applications and access technologies and does not require any additional network nodes. It is based on a Linux Mobile IPv6 stack developed by GO – an Ericsson co-funded research project in Helsinki University of Technology. The Home Agent functionality is provided on a commercial Ericsson high performance dual stack Router.
