Abstract: A foreign wireless communication system is operated in a local communication network as if the foreign wireless communication system were a local wireless communication system. A data communication link is established between the wireless communication system and a service provider in a local wireless communication network. An outgoing request for authentication information is communicated from the wireless communication system to a remote administration system over the data communication link. The authentication information is received over the data communication link from the administration system and is transmitted over a signal link from the wireless communication system to the service provider. A requested wireless communication service is received at the wireless communication system based on authentication of the wireless communication system by the service provider using the authentication information.

Abstract: The present invention provides a virtual subscriber identity module (vSIM) for network connection. The vSIM includes a memory and at least one processor. The memory is configured to store a remote SIM (rSIM) implemented as a software card. The at least one processor is coupled to the memory and configured to: register to a first network and download a vSIM profile from a vSIM server via the rSIM; and complete a registration to a second network using the vSIM profile for activating a vSIM service to connect to the second network. The present invention further provides an apparatus including the vSIM, a vSIM server for communicating with the apparatus, and a method performed by the apparatus.

Abstract: The present invention provides a vSIM module for a portable apparatus. The portable apparatus at least includes a slot. The vSIM module comprises a radio frequency chip, a baseband processor, a memory, an application processor, and a connector. The radio frequency chip is couple to an antenna. The baseband processor is coupled to the radio frequency chip. The memory is configured to store a vSIM connectivity management program. The application processor is coupled to the memory for executing the vSIM connectivity management program. The connector is configured to connect with the slot of the portable apparatus. When the vSIM connectivity management program is executed by the application processor, a vSIM service is activated.

Abstract: An authentication bank for a wireless communication system is disclosed. The authentication bank comprises a plurality of physical identification modules. A physical identification module may include one or more memory, processors, programs, and computer readable media storing subscriber identity module and authentication information. At least one of the one or more programs stored in the memory may comprise instructions executable by at least one of the one or more processors. The executable instructions may cause the one or more processors to receive a request, from an authentication server, for associating the subscriber identity module (SIM) with a foreign wireless communication client or an extension unit, retrieve subscriber identity information and authentication information for the foreign wireless communication client or the extension unit from the SIM, and send the subscriber identity information and the authentication information to the authentication server.
