Agenda

• Review of WP3 activities• Security issues related to WP3• MobiHealth Communication Architecture• Technical requirements of trial scenarios• Data collection tool• WP3 Deliverables• Planning

3

Review of WP3 activities

• GPRS infrastructure:– Communication architecture

– Technical requirements of trials

– Security requirements

– Data collection tool

– Roaming

• UMTS infrastructure:– Viability??

4

• Fine tuning and integration of the BAN applications:– Integration with WP2

– Test the operation of the whole system:• Security level

• Quality of service

• Deliverable D3.1: Trial ready GPRS and UMTS networks (TME)

• Deliverable D3.2: MobiHealth system (CMG)

Review of WP3 activities

5

Security issues in WP3

• Integration with WP2

• Alternatives of connections to WSB:– Using HTTP: Rely on GPRS security

– Using HTTPs

– Tunneling: IPsec

6

MobiHealth Communication

Architecture• Requirements needed to support a MobiHealth BAN:– Integration of the BAN applications

– Interface with WP2

• Wireless Service Broker– Integration with operator (Telia, TME)

– Integration with health broker sites

7

WSB (Wireless Service Broker)

For MobiHealth project, there will be a

connection between GGSN and WSB, via

a tunnel connection (VPN) over Internet,

and a tunnel connection between the

WSB and the Application Server. In this

way we will have a secure connection.

8

WSB functionalities• Users authentication.• Secure access and security management.• Protocol conversion (SMS support, WAP support).• Personalisation (homepage).• Service navigation.• (Multimedia) messaging relay.• Synchronization.• System monitoring and system management.• Storage.• Location management.• Multi device support.• WAP 2.0 compliant.• In situations of out of coverage, the Push capability works

(activate when MBU is in sleep mode and deliver content when device is available; Push Proxy Gateway stored data).

9

Requirements for operators

• MSISDN (or equivalent user identifier) forwarding.

• IP address forwarding.• Location data forwarding.• VPN infrastructure

(recommended).• IPsec protocol.

Location based services -TMEMovilForum provides two location platforms, Geo-IP

and GPP, that allow to develop location based services, for any device (WAP, PDAs, handsets, laptops...).– Geo IP provides location information in WAP connections.

Initiated by user. The user authorizates to be located.

– GPP (Genasys Positioning Platform) provides location information for any acces: WEB, WAP, SMS...Initiated by user or content provider. (Passive location, for example tracking services).

15

• Cell-ID accuracy: The network provides the location information of the cell in which the user is. The Cell-ID accuracy depends on the cell size:– Urban area: 50-500 m.

– Rural area: 1-20 km.

• GSM or GPRS access.

• Possible improvements: The use of TA (Timing Advance) parameter improves the accuracy, but only with Ericsson BSCs.

Location based services -TME

16

• MovilForum provides open APIs (Application Program Interface) in order to access to the location platform.

• Legal problems: Requests for positioning information is only processed if the user has given his authorization.
