  • Publication number: 20150139078
    Abstract: A method and apparatus for supporting Non-Access Stratum (NAS) communication between a User Equipment (UE) and a Mobility Management Entity (MME) efficiently by addressing the signaling problems occurring between the UE and the MME in a situation where it is necessary for a network node to identify the UE and acquire UE information, if there is any, from another network node to which the UE has been attached, are provided. The method for communication between the UE and network based on the NAS protocol messages and operations is implemented with the involvement a UE, an MME, and an old MME or an old Serving General Packet Radio Service (GPRS) Support Node (SGSN) to which the UE has been attached before so as to facilitate discovering a best node using the UE information acquired from the old MME or old SGSN during the communication between the UE and the network, resulting in a reduction of a communication delay between the UE and network and an improvement of communication efficiency.

  • Patent number: 9037112
    Abstract: The present invention provides a method and system for secured remote provisioning of a universal integrated circuit card of a user equipment. A system includes a user equipment for initiating a request for remote provisioning of an universal integrated circuit card (UICC) in the user equipment, where the request for remote provisioning includes a machine identifier (MID) associated with the user equipment and a public land mobile network (PLMN) identifier (ID) associated with an network operator. The system also includes at least one shared key management server for dynamically generating security keys and an operator shared key using the security keys, the MID. Moreover, the system includes an operator network for generating a subscription key using the operator shared key and an international mobile subscriber identity (IMSI), and provisioning the IMSI in a secured manner to the UICC of the user equipment using the security keys.
