2 Index Introduction to GPRS and UMTS networks –Architecture overview –Services GPRS and UMTS situation in each trial site –GPRS communication architecture Commercially available providers GPRS Roaming partnership Coverage maps –UMTS state

3 Technical requirements and limitations in each trial scenario –Bandwidth –Coverage and availability –Reliability Conclusions about TCP and UDP performance –Traffic management –Security –Mobility Index (II)

4 GPRS situation in each trial site Selected operators: No problems related to coverage areas. Roaming: Not available between the trial sites with the selected operators CountryOperator GermanyD2- Vodafone SpainTelefónica Móviles (Partner) SwedenTelia (Partner) The NetherlandsO2

7 Technical requirements and limitations in each trial scenario (II) RELIABILITY Conclusions about TCP vs UDP –TCP protocol is suitable for transporting BAN control data from the End-Host to BAN –The BAN data can be transported using UDP although some data may be lost

8 Technical requirements and limitations in each trial scenario (III) TRAFFIC MANAGEMENT Operators involved can´t guarantee the priority of the data over the voice so data traffic may be affected by a voice congestion situation.

9 Technical requirements and limitations in each trial scenario (IV) SECURITY Two security services are required for patients data in GPRS/UMTS networks: Data confidentiality and authentication Security protocols used in MobiHealth from the MS to the server: –Transport Layer SSL connection, data encryption, X.509 certificates-based client, Server authentication –Data link layer security provided by the Radio Access Network (authentication and data encryption)

10 Technical requirements and limitations in each trial scenario (V) MOBILITY GPRS: –Roaming functionality allows the users to establish GPRS connections from a foreign country. – If the user roams to another network during a GPRS connection, the link goes down. – In the same network, the handovers don't produce any disconnection. UMTS: Only handover could be supported at first phase.
