JAIN SLEE vs SIP Servlet Which is the best choice for an IMS application server?

摘要

The IP Multimedia System (IMS) is the next generation network architecture in telecommunication. Vendors are promoting two Java application server standards (JAIN SLEE and SIP Servlet) for the services layer of the IMS. This paper outlines the aims, objectives and features of the two standards. Requirements typical of IMS applications are identified and used to compare and contrast JAIN SLEE and SIP Servlet and evaluate their suitability for building services in the IMS. It is shown that a SIP API integrated with a JAIN SLEE implementation creates a powerful and simple to use SIP environment in a standard carrier grade communications application server suitable for typical tier one operator requirements.
