Abstract
An IP Multimedia Subsystem (IMS) network provides access to Web services. A HyperText Transfer Protocol (HTTP) message addressed to a Web Service Provider along with the IMS identifier from a device is received in the IMS network. The IMS network validates registration of the device. The IMS identifier and the HTTP message are communicated to the Web Service Provider. A Web service is conveyed from the Web Service Provider to the device.
Claims25
A method of operating an IP Multimedia Subsystem (IMS) network to provide access to Web services, comprising:
- receiving a HyperText Transfer Protocol (HTTP) message addressed to a Web Service Provider along with an IMS identifier from a device;
- validating registration of the device in the IMS network;
- communicating the IMS identifier and the HTTP message to the Web Service Provider;
- and
- conveying a Web service from the Web Service Provider to the device.
The method of Claim I, wherein validating the registration of the device comprises:
- querying a Home Subscriber Server (HSS) database to determine if the device has registered with the IMS network.
A method of operating a device to access Web services, comprising:
- registering with an IP Multimedia Subsystem (IMS) network;
- transmitting a HyperText Transfer Protocol (HTTP) message addressed to a Web Service Provider along with an IMS identifier to the IMS network;
- and
- receiving a Web service from the Web Service Provider without conducting an authentication communication corresponding to the transmitted HTTP message.
A method of operating a Web service system, comprising:
- receiving an IP Multimedia Subsystem (IMS) identifier and an HTTP message from a device via an IMS network;
- identifying the device via the IMS identifier at the Web service system;
- and
- providing a Web service to the device via the IMS network responsive to the identification of the device.
An IP Multimedia Subsystem (IMS) network, comprising:
- a Web-Services Control Function (W-SCF) that is configured to receive a HyperText Transfer Protocol (HTTP) message addressed to a Web Service Provider along with an IMS identifier from a device, validate registration of the device in the IMS network, and communicate the IMS identifier and the HTTP message to the Web Service Provider.
