  • Publication number: 20200367014
    Abstract: Methods and apparatuses for exposure of presence reporting area (PRA) functionality are disclosed for a wireless communication system. According to an embodiment, a service capability exposure function (SCEF) entity receives, from a requesting server, a first request for initiating PRA functionality for at least one user equipment (UE). The PRA functionality is used to monitor whether the at least one UE is located in at least one area of interest. The SCEF entity obtains at least one monitored result for the at least one UE from a mobility management node via a home subscriber server (HSS) or via a policy and charging rules function (PCRF) entity. The SCEF entity sends the at least one monitored result to the requesting server.

  • Publication number: 20200288539
    Abstract: The embodiments herein relate to reducing signaling for DoNAS (Data over Non-Access Stratum) via SGi. In one embodiment, there proposes a method (400) in a mobility management node (203), comprising: establishing (S401) an S11-U connection between the mobility management node (203) and a gateway node (204); monitoring (S402) the frequency of data transferring request for a wireless device (201); and deciding (S404) whether or not to release the S11-U connection based on the frequency of data transferring request. With the embodiments herein, the signaling between the mobility management node and the gateway node can be significantly reduced, without introducing extra signaling or message to the existing network.

  • Patent number: 10623939
    Abstract: A method in a mobility management node for handling information in a network. The node is associated with a wireless device being served by a serving network. The node obtains information about that at least one of the serving network and a time zone and a UCI, has been changed for the device, and information about that the change has not been transmitted to a SGW. When at least one of the serving network and the time zone and the UCI, has been changed, and information about the change has not been transmitted to the SGW, the node transmits the information about at least one of the changed serving network and time zone and UCI, to the SGW, enabling the SGW to forward this information to a PGW.

  • Patent number: 10251209
    Abstract: A smart 3GDT schema has been disclosed, in detail, a method for controlling the communication of a network system has been disclosed. The network system comprises a UE, a NodeB, a RNC, a SGSN, and a GW. The UE is arranged to be in communication with the RNC via the NodeB, and the RNC is arranged to be in communication with the SGSN which in turn being arranged to be in communication with the GW for non-3GDT communication of the network system, or the RNC is arranged to be in communication with the GW for 3GDT communication of the network system. In this method, statistics of payload transferred between the UE and the GW has been monitored, and if the statistics of payload within a predetermined time period exceeds a first threshold, and the UE is in the non-3GDT communication, then switching the non-3GDT communication to the 3GDT communication. The present application has also disclosed the SGSN, GW, and the network system adaptive to perform the method.

  • Patent number: 10225882
    Abstract: A method in an access point (AP) for setting an inactivity timer in a radio communication network comprising the AP, a mobile management entity (MME) and a session management entity (SME). The method includes obtaining an inactivity timer value for one or more user equipments (UEs) served by the AP and transmitting the inactivity timer value to the MME for notifying the SME of the inactivity timer value for the one or more UEs. For each of the one or more UEs, the AP and the SME respectively maintain an inactivity timer associated with the UE based on the inactivity timer value and remove resources locally used for the UE when the inactivity timer expires.
