Abstract: A method and apparatus provide access to communication services using dynamically assigned user credentials. The method includes establishing a communication connection with a first communication network (such as GSM, UMTS, CDMA, or LTE networks) using a real user credential (e.g., a SIM, a USIM, or an R-UIM card or certificates) in a first communication module, utilizing the first communication connection to request the dynamically assigned user credential from a remote management system, and registering a second communication module into the second communication network. The second communication connection is then tethered to allow other devices to access the Internet or other network.

Abstract: An interworking solution only requires that Greenfield LTE deploy the IWF and IMS AS, and set up the connections between their MME and IWF for the IMSI attach procedure. The solution uses an IMS client that can be installed on the roamer's devices. Thus once the roamer is attached to the LTE network together with IMSI attach via IWF function, and registered into the IMS system, the roamer can receive voice call and SMS by the original phone number, even though the LTE operator network does not support CSFB.

Abstract: A method and system for completing the authentication process in a second communication network (such as Wi-Fi or WiMAX) utilizes a user credential of a first communication network, such as GSM, UMTS, CDMA, or LTE. Preferably, the user credential is a SIM card, a USIM card, a R-UIM card, or a functionally similar component. The system includes a client and an authentication platform that retrieves Service State information of the user credential in the first communication network and passes the information to the authentication platform of the second communication network. The client is granted access to the second communication network after the authentication platform validates the client's service and subscription status with the first communication network.

Abstract: A method and system for completing the authentication process of a user device in a second communication network (such as Wi-Fi or WiMAX) utilizes the user credential (such as a SIM card, a USIM card, or a RUIM card) of a first communication network (such as GSM, CDMA, EDGE, or LTE). A client, such as a software module, executes on the wireless device. An authentication platform retrieves the SIM card credential information in the first communication network and passes the information to the authentication platform of the second communication network, thereby granting the client access to the second communication after the authentication platform validates with the first communication network.

Abstract: The present invention is directed to systems for and methods of using dual mode handsets or softphone client for voice, sms, and data services. In one embodiment of the present invention, a mobile handset uses a SIP User Agent to register on a visiting network. The mobile handset generates SIP REGISTER messages. The SIP REGISTER messages are translated into corresponding MAP registration (or RADIUS message) and authentication commands, allowing system to contact the HPLMN HLR (or home AAA) associated with the mobile device to authenticate the mobile device and register it on a VLR of a visiting network. MAP responses (or RADIUS response) are translated to corresponding SIP commands that are forwarded to the mobile device, thereby completing the connection set up.
