  • Patent number: 10313869
    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: 9357449
    Abstract: The present disclosure relates to a communication method between a terminal and a network during an inter PLMN (public land mobile network) handover in a mobile communication network that shares an E-UTRAN (evolved universal terrestrial radio access network), and a mobile communication system thereof. According to the present invention, the terminal performs E-UTRAN registration through a base station (eNB) and an MME (MME), updates a routing area, activates ISR (idle state signaling reduction), receives a handover command to the previous PLMN or another PLMN and transmits a location update request message to the MME while the handover is being executed. As such, a communication disconnect or any authentication or security failure during the inter PLMN handover of the terminal can be avoided.
