Publication number: 20200367014Abstract: 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.Type: ApplicationFiled: January 31, 2019Publication date: November 19, 2020Inventors: Zhiwei Qu, Jinyin ZHU

Patent number: 10623939Abstract: 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.Type: GrantFiled: December 10, 2018Date of Patent: April 14, 2020Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Mei Dong, Zhiwei Qu, Yong Yang, Dongmei Zhu

Patent number: 10251209Abstract: 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.Type: GrantFiled: February 14, 2012Date of Patent: April 2, 2019Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Di Liu, Qi Xia, Huiping Ding, Ping Sha, Zhiwei Qu, Zhao Yu, Lei Guo
