| Abstract: |
| The location-based services is considered to be the next climax of the telecom value-added services
after the SMS (short message system). This paper introduces a service flow describing language XPL
(extended-calling process language) which mainly focuses on the value-added service in telecom field before. This
paper presents a geography information service describing language GDL (geography description language) based
on the prior work. XPL and GDL have the ability to describe LBS-oriented telecom services in coordination. Those
languages have high level in abstractness, and they can be easily used and are fast at developing service. This paper
also presents the supporting system of those languages. Due to the basis of SOA (services-oriented architecture), the
supporting system suits the service creation under the condition of net merging. |
