A communication device having a controller transmits to a communication system a PKI certificate. Encrypted communications may commence responsive to receiving a public key. The communication system can have a plurality of network elements that integrate operations of a circuit-switched communication network and a packet-switched communication network.

Methods, systems, devices and products for authentication

A system that incorporates teachings of the present disclosure may include, for example, a communication device having a controller to transmit to a communication system a PKI certificate, and engage in encrypted communications responsive to receiving a public key from the communication system. The communication system can have a plurality of network elements that integrate operations of a circuit-switched communication network and a packet-switched communication network. Other embodiments are disclosed.

System and method for authenticating a communication device

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.

Systems, methods and computer program products for providing access to web services via device authentication in an IMS network

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.

A network connectivity status of user equipment (UE) is detected. Detection of the network connectivity status of the UE may include, for example, detecting termination of network connectivity of the UE responsive to a communication to the network by the UE, receiving a termination message from the UE at the bootstrapping server function (BSF), receiving notification of de-registration of the UE from a home subscriber server (HSS) and/or detecting a loss of communications between the UE and the network. A bootstrapping server function (BSF) communicates with at least one network application function (NAF) responsive to detection of the network connectivity status to terminate a plurality of sessions associated with the UE.

Methods of switching personas associated with an asserted identity by determining a selected persona based on at least one of a sequence of digits entered during initiation of a call are provided. The at least one of the sequence of digits indicates a request for a persona associated with an asserted identity. It is indicated that an original persona associated with the asserted identity should be switched to the selected persona associated with the asserted identity if it is determined that the original persona and the selected persona are different. Related systems and computer program products are provided.

Methods, systems and computer program products for providing access to personal profiles in communications systems

A communication network provides access to a network service by providing an additional level of authentication beyond device level authentication. Operations include receiving a message at a Bootstrapping Server Function (BSF) from User Equipment (UE) that additional authentication beyond UE authentication is required for UE access to a network service, and performing an authentication protocol between the BSF and a Home Subscriber System (HSS) to authenticate an identity associated with the UE responsive to receiving the message.

A Session Initiation Protocol (SIP) message including an embedded web service request is received at an IMS network from a device. The received SIP message is protocol translated to generate a non-IMS message including the web service request. The non-IMS message is conveyed to a web service provider, and a requested web service corresponding to the non-IMS message is conveyed from the web service provider to the device. The SIP message may include a SIP INVITE message containing an embedded SOAP message.
