An Extensible Design for Service Access Gateway Based on REST Pattern

The present development pattern of Web Service has gradually transformed from Soap to REST. If the telecom network is fused with Web Service, it must solve the problem that Web Service developed the REST pattern uses the telecom network capacity provided by operators. In this paper, the design for Service Access Gateway proposed is based on the SIG model of Ericsson to solve the problem. This paper will analyze the model of gateway from two aspects which are structure of layers and trait of functions, and carefully describe the solution of system to support the REST access to the Service Access Gateway.
