Abstract: A network node, method, and mobile terminal for providing circuit-switched (CS) voice calls to a mobile terminal operating in a packet-switched (PS)-only network. A control node such as an EPC node in an SAE/LTE PS-only network is modified to mimic the messaging functionality of a Serving GPRS Service Node (SGSN). The EPC node is connected to an MSC/VLR in a CS network through a Gs interface. The EPC node registers the terminal with the MSC/VLR and provides a VLR TMSI to the terminal. When the MSC/VLR receives an incoming CS voice call for the terminal, the MSC/VLR notifies the EPC node, which sends a paging message to the terminal. To set up the CS voice call, the terminal sends a paging response directly to the MSC/VLR.

Abstract: An end-user mobile device has a cellular network modem that is capable of communication over multiple carrier access networks. Prior to activation of the device with any cellular carrier, a secure credential memory stores a set of pre-activation credentials. One or more device agents detect an attempt by a user to use the device in a manner that would require a cellular connection to communicate Internet data, where such attempt is not allowed by a pre-activation service policy. Such an occurrence triggers the device agents to guide a device activation sequence that uses the pre-activation credentials to connect via a carrier access network to an activation server, which downloads service options to the device for multiple cellular service carriers. When the user selects one of the options, the activation sequence further guides the device to receive and securely store permanent credentials. The device subsequently uses the permanent credentials to access the network of the selected service carrier.
