USER AUTHENTICATION AND RESOURCE MANAGEMENT IN A CELLULAR NETWORK

摘要

User authentication for accessing a service provided over a cellular network is provided. A user device for communication with the cellular network has at least one unique identifier associated with the cellular network. An authentication code for accessing the service over the cellular network is used, the authentication code being based on security information that is based on the at least one unique identifier and may also be based on a service credential that is unknown to the user device. The security information may be communicated from the user device to an authentication device separate from the user device over a secondary communications link. The authentication code may be generated at the authentication device.
