Web services are evolving quickly in terms of standardization. Technology and wireless networks exact requirements upon web services used via wireless connections, such as mobile networks. The interoperability of services is essential in wireless networks because cost effective development and deployment of new wireless services for a user requires maximum utilization of service infrastructure. At the moment, constraints of service interface description models and implementation of services restrict interoperability between services. To achieve interoperability and composability, a standardized way to describe services and service interfaces is required, and for this reason standardization bodies are promoting the set of Extensible Markup Language (XML) technologies as the basis for a set of common standars. To respond to the challenges concerning service interoperability, this paper illustrates three widely known web standars that promote interoperability between web services - SOAP (Simple Object Access Protocol), WSDL (Web Services Definition Language) and UDDI (Universal Description, Discovery and Integration) - and proposes an interface description model for wireless Internet services. The proposed model takes into account architectural level service description in a novel way and presents its implementaion using XML.
