Patent number: 10412579Abstract: A root key (K_iwf) is derived at a network and sent to MTC UE (10). The K_iwf is used for deriving subkeys for protecting communication between MTC UE (10) and MTC-IWF (20). In a case where HSS (30) derives the K_iwf, HSS (30) send to MTC-IWF (20) the K_iwf in a new message (Update Subscriber Information). In a case where MME (40) derives the K_iwf, MME (40) sends the K_iwf through HSS (30) or directly to MTC-IWF (20). MTC-IWF (20) can derive the K_iwf itself. The K_iwf is sent through MME (40) to MTC UE (10) by use of a NAS SMC or Attach Accept message, or sent from MTC-IWF (20) directly to MTC UE (10). In a case where the K_iwf is sent from MME (40), MME (40) receives the K_iwf from HSS (30) in an Authentication Data Response message, or from MTC-IWF (20) directly.Type: GrantFiled: December 3, 2013Date of Patent: September 10, 2019Assignee: NEC CORPORATIONInventors: Xiaowei Zhang, Anand Raghawa Prasad

Patent number: 10404677Abstract: Upon receiving a triggering message from a MTC server (20), a network (10) verifies if the MTC server (20) is authorized to trigger a target MTC device (30) and also if the MTC device (30) is authorized to respond the triggering message, by comparing an MTC device ID and MTC server ID (and optionally information on subscription) which are include in the triggering message with authorized ones. Upon succeeding in the verification, the network (10) checks a trigger type included in the triggering message to verify if the triggering message is authorized to be sent to the MTC device (30). Upon succeeding in the check, the network (10) forwards the triggering message to the MTC device (30). The network (10) also validates a response from the MTC device (30), by checking whether the MTC device (30) is allowed to communicate with the addressed. MTC server (20).Type: GrantFiled: September 27, 2018Date of Patent: September 3, 2019Assignee: NEC CorporationInventors: Xiaowei Zhang, Anand Raghawa Prasad

Patent number: 10404479Abstract: In order for charging SDT and MTC device trigger over control plane, there is provided a network node (40) that relays messages over a control plane (T5 and Tsp) between an MTC device (10) and an SCS (50). The network node (40) counts the number of messages successfully relayed, and generates a CDR in accordance with the counted number. The messages are SDT messages delivered from the MTC device (10) to the SCS (50), SDT messages delivered from the SCS (50) to the MTC device (10), or MTC device trigger messages delivered from the SCS (50) to the MTC device (10). The network node (40) transfers the CDR to an OCF (31) or a CDF (32).Type: GrantFiled: August 4, 2014Date of Patent: September 3, 2019Assignee: NEC CORPORATIONInventors: Xiaowei Zhang, Anand Raghawa Prasad

Publication number: 20190253939Abstract: A UE (10) provides information on potential S?eNB(s). The information is forwarded from an MeNB (20_1) to an M?eNB (20_2) such that the M?eNB (20_2) can determine, before the handover happens, whether the M?eNB (20_2) will configure a new SeNB (S?eNB) and which S?eNB the M?eNB (20_2) will configure. In one of options, the MeNB (20_1) derives a key S?-KeNB for communication protection between the UE (10) and the S?eNB (30_1), and send the S?-KeNB to the M?eNB (20_2). In another option, the M?eNB (20_2) derives the S?-KeNB from a key KeNB* received from the MeNB (20_1). The M?eNB (20_2) sends the S?-KeNB to the S?eNB (30_1). Moreover, there are also provided several variations to perform SeNB Release, SeNB Addition, Bearer Modification and the like, in which the order and/or timing thereof can be different during the handover procedure.Type: ApplicationFiled: April 18, 2019Publication date: August 15, 2019Applicant: NEC CORPORATIONInventors: Xiaowei ZHANG, Anand Raghawa PRASAD

Patent number: 10375614Abstract: An SeNB informs an MeNB that it can configure bearers for the given UE. At this time, the MeNB manages the DRB status, and then sends a key S-KeNB to the SeNB. The MeNB also sends a KSI for the S-KeNB to both of the UE and the SeNB. After this procedure, the MeNB informs an EPC (MME and S-GW) about the new bearer configured at the SeNB, such that the S-GW 50 can start offloading the bearer(s) to the SeNB 30. Prior to the offloading, the EPC network entity (MME or S-GW) performs verification that: 1) whether the request is coming from authenticated source (MeNB); and 2) whether the SeNB is a valid eNB to which the traffic can be offload.Type: GrantFiled: March 5, 2015Date of Patent: August 6, 2019Assignee: NEC CORPORATIONInventors: Xiaowei Zhang, Anand Raghawa Prasad

Publication number: 20190200231Abstract: In order for making MTC more efficient and/or secure, a base station forming a communication system connects a UE to a core network. A node serves as an entering point to the core network for a service provider, and transmits traffic between the service provider and the UE. The node establishes, as a connection to the base station, a first connection for directly transceiving messages between the node and the base station. Alternatively, the node establishes a second connection for transparently transceiving the messages through a different node that is placed within the core network and has established a different secure connection to the base station.Type: ApplicationFiled: February 27, 2019Publication date: June 27, 2019Applicant: NEC CorporationInventors: Xiaowei ZHANG, Anand Raghawa PRASAD, Andreas KUNZ, Genadi VELEV, Toshiyuki TAMURA

Publication number: 20190153316Abstract: Phosphor, a preparation method for the phosphor, and a light emitting device having the phosphor. The phosphor comprises an inorganic compound which at least comprises an element M, an element A, an element D, and an element R; the element M is one or two elements selected from the group consisting of Lu, La, Pr, Nd, Sm, Y, Tb, and Gd and must comprise Lu; the element A is Si and/or Ge; the element D is one or two elements selected from the group consisting of O, N, and F and must comprise N; the element R is Ce and/or Dy. Since the ionic radius of Lu3+ is smaller than that of La3+, when the inorganic compound comprises element Lu, the original ligand site would be contracted. In order to reduce lattice distortion due to the ligand site contraction, the adjacent ligand site expands, and the photochromic property is adjusted.Type: ApplicationFiled: June 30, 2017Publication date: May 23, 2019Applicant: GRIREM ADVANCED MATERIALS CO., LTD.Inventors: Ronghui LIU, Weidong ZHUANG, Fu DU, Yuanhong LIU, Wei GAO, Xia ZHANG, Huibing XU, Chunpei YAN, Xiaowei ZHANG

Publication number: 20190089802Abstract: In order for efficiently managing communications between a UE (10) and multiple SCSs (20_1-20_n), the UE (10) includes, in one message, multiple pieces of data to be transmitted to the SCSs (20_1-20_n), and sends the message to an MTC-IWF (30). The MTC-IWF (30) receives the message from the UE (10), and distributes the date to the SCSs (20_1-20_n). Each of the SCSs sends (20_1-20_n), to the MTC-IWF (30), data to be transmitted to the UE (10) and an indicator that indicates for the SCSs (20_1-20 n) the time tolerance until the data is transmitted to the UE (10). The MTC-IWF (30) receives the data and the indicators from the SCSs (20_1-20_n), and determines when to forward the data to the UE (10) based on the indicators.Type: ApplicationFiled: September 10, 2018Publication date: March 21, 2019Applicant: NEC CorporationInventors: Xiaowei ZHANG, Anand Raghawa Prasad
