Abstract
A communication device including a non-SIM based client is authenticated for accessing an IMS network. An internet protocol identity is received from the communication device. The internet protocol identity is not associated with a SIM. Authentication information associated with the internet protocol identity is requested and received from the communication device. A determination is made whether the communication device is authenticated based on the internet protocol identity and the authentication information. If the communication device is determined to be authenticated, the communication device is allowed access to the IMS network.
