Systems, Methods and Computer Program Products Supporting Provision of Web Services Using IMS

A web service request from a device is received at a web service provider. The web service request is authenticated at the web service provider using the IMS network. A requested web service is provided to the device responsive to the authentication of the web service request. The web service request may be received via a path outside of the IMS network, e.g., over a network using HTTP or other non-IMS protocol. The requested web service may also be provided using a web service response communicated to the device via a path outside of the IMS network.
