Purpose: Open service access (OSA) is a flexible and efficient approach for mobile service deployment. In OSA, network functionality offered to application servers (ASs) is defined by a set of service capability features (SCFs). The AS implements services by accessing the service capability through the standardized OSA application programming interface. Design/methodology/approach: The paper shows how the AS provides services by integrating the services supported by the SCFs. Then it uses the OSA mutual authentication and the push to talk over cellular service to illustrate the interaction among the AS modules and how the AS interacts with the framework and the SCFs. Findings: With this environment, the service developers are not required to access the details of the underlying mobile network, and thus the service deployment can be sped up. The purpose of this paper is to propose an AS architecture. Originality/value: This paper proposed an OSA AS architecture. Based on this architecture, a new application is created by implementing the appLogic module that invokes the SCFs through the appService modules and appService callback modules.
