3. What are the main components of a mobile Web services framework?
According to ESA (2004) presented the main components of a mobile Web services framework:
Mobile Server
The Mobile Server is a mobile remote computer; linked to the Internet via an Inmarsat Regional Broadband Global Area Network (RBGAN) User Terminal (UT) The mobile web services are active on this server. The mobile Server could be used as a server or as a client PC and it just accept requests from the Gatekeeper
Gatekeeper
The Gatekeeper is placed on the terrestrial Internet, and acts as the sole gateway to the Mobile Server. It is used to perform authentication and authorization of requests before sending them to the Mobile Server. Moreover, the Gatekeeper store buffered data, so it will enable more economic usage of the satellite link.
RBGAN UT / Thuraya Satellite/ RBGAN SAS
The physical connection between the remote web server and the Gatekeeper is established using a Satellite Access Station, a Telecommunications Satellite and a satellite modem.
GPS / Data Acquisition system / Web cam
The mobile Server is connected to a set of peripherals, such as a GPS device, a web cam or a Data Acquisition system. From these devices, data is collected by the web service.
Application server / Client PC
The Gatekeeper handles requests from clients over the Internet. A client can be a PC with a web browser, or another application using a http Simple Object Application Protocol – SOAP request.

4. Visit an Airline Web site and search information on WAP or SMS or 3G mobile application access to booking airline services. The same services exist in banking. How do both industries compare?
I have visited the Jetstar website and accessed the SMS booking section. This facility allows people to make bookings 24 hours a day with the airline by SMS or a mobile phone. This advantage of this JetSMS technology support user to either book a flight or enquire on a low fare at any time or place with mobile coverage are immense (zdnet, 2004).
The SMS service provided in bank used to many purposes that enhance the security is one of them. For example, I browsed the netbank service in Commonwealths Bank and transfer the money. As I transfer money to new account, a security code will be sent to my mobile via SMS to ensure that I am a holder account.
The service for banking is different from airline booking that that it require more secure service user follow up the regulation properly.
