Mobile Service - Definition • “A radiocommunication service between mobile and land stations, or Mobile Service - Definition • “A radiocommunication service between mobile and land stations, or between mobile stations. ” – traditional, short • “Radiocommunications services between ships, aircraft, road vehicles, or hand-held terminal stations for use while in motion or between such stations and fixed points on land. ” – official, by WTO • “Any service that can be operated on a mobile device, such as both voice and data services, for example, roaming, SMS and MMS, video streaming, location-based services, etc. ” – technically oriented www. sti-innsbruck. at 3

Mobile Services vs. Web Services • Many Web Services and APIs were originally developed Mobile Services vs. Web Services • Many Web Services and APIs were originally developed with server to server or server to browser in mind, not mobile applications • Mobile platforms have their own set of challenges given: – – – Bandwidth Memory and CPU Availability Storage Capacity Connectivity Options and Issues Security User Interaction and Display www. sti-innsbruck. at Web Service

Making Mobile Services Widespread Mobile services have not (yet) reached the success of Web Making Mobile Services Widespread Mobile services have not (yet) reached the success of Web • If mobile services are to repeat the success of the Web they have to be: • simple to use, • simple to find, • simple to trust, • simple to create/set up. • These are the design goals of numerous projects, such as “SMS: Simple Mobile Services”, OPUCE, m: Ciudad. 15/03/2018 www. sti-innsbruck. at NGMAST 2008 Page 5
