Abstract: In a portable device position estimation system, a vehicle-mounted system includes a transceiver and intercept devices. The vehicle-mounted system determines a first propagation time being a propagation time of a wireless signal from the transceiver to a portable device, based on a round trip time being a time between the transceiver transmitting a response request signal and the transceiver receiving a response signal from the portable device. The vehicle-mounted system determines a second propagation time being a propagation time of a wireless signal from the portable device to the intercept device based on the round trip time and a signal reception interval being a time between the intercept device receiving the response request signal and the intercept device receiving the response signal.

Abstract: The present invention relates to a positioning method and system based on a Wi-Fi IoT device network, wherein positioning monitoring nodes in a subnet respectively receives, within an information receiving and transmitting range thereof, a data packet sent by a same positioning target device, records corresponding data packet receipt clock information, and provides the data packet receipt clock information and identification information of the positioning target device to the subnet master node; the subnet master node utilizes signal arrival time differences between a plurality of positioning monitoring nodes receiving the data packet from the same positioning target device, and mutual physical distances between the positioning monitoring nodes, to compute the distance differences of the positioning target device with respect to the plurality of positioning monitoring nodes, and determine a position of the positioning target device in a physical coverage range of the subnet.

Abstract: An MEC node, by analyzing signaling information transmitted between each of a plurality of eNBs and an MME, collects at least one of information indicating a mobility state and information indicating a communication state of a UE present within cells of the plurality of base stations. The MEC node decides a paging range based on the information collected as above upon receiving a paging message for paging the UE, the paging message having been transmitted by MME to one or more eNBs in accordance with a predetermined paging policy. The MEC node transmits a paging message for paging the UE to each eNB present in the decided paging range.

Abstract: A device may use sidelink request and sidelink response (e.g., DSS/STS and DRS) resources (in a sub-band) of different sizes depending on whether the sub-band is a primary sub-band or secondary sub-band. The device may transmit more information in the request/response resources of a primary sub-band than in the request/response resources of a secondary sub-band. The device may transmit small amounts of information in its request/response resources in secondary sub-bands. The resources in the secondary sub-bands may include, for example, reference signals, and signals indicating occupation of the sub-band. The device may utilize tone signaling for request/response signaling in the secondary sub-bands (at least because the amount of information being conveyed in the secondary sub-bands is small) and digital signaling in the primary sub-band (at least because the amount of information being conveyed in the primary sub-band is large in comparison to that being conveyed in the secondary sub-bands).

Abstract: A method for enabling a charging of packet switched data transfer between an authorized customer and a network. The method includes transferring a total data volume via at least a first data path and a second data path between an equipment related to the authorized customer and a hybrid access aggregation point (HAAP) as an access to the network. Each of the at least a first data path and a second data bath use a different access technology for transferring its respective part of the total data volume. The total data volume is determined as a sum of the respective parts of the total data volume transferred in both the first path and the second path. The total data volume is used by a central charging unit for a charging.

Abstract: Disclosed herein are devices, systems and methods for processing remotely at a remote server or cloud platform data relating to emergency communications (phone calls, text messages, etc.) received by Public Safety Answering Points (PSAPs), in particular emergency communications received and handled by emergency communication handling systems at the PSAP which support serial communication and have no network connectivity. To overcome this limitation, one or more serial-to-Internet Protocol (IP) gateways are deployed in the PSAP to: (a) receive the incident data from the emergency communication handling systems and encapsulate the incident data in its raw form in IP packets, and (b) transmit the IP packets to the remote processing system. The remote processing system then parses the incident data according to parsing rule(s) applicable for the PSAP from which the incident data is received, format the incident data and process the formatted data to optimize communication handling operation of the PSAPs.

Abstract: This document describes techniques and apparatuses for releasing information to improve cell selection in different resource control states. To improve communication performance, a user equipment (UE) 110 releases dedicated cell-selection information 306, which may not be appropriate as the UE 110 moves to different geographical locations and transitions to different resource control states 218. Different situations cause the UE 110 to release the dedicated cell-selection information 306, including performing a cell-selection procedure in an inactive state that selects another cell that does not support the inactive state, processing a paging message 308, or transitioning from the inactive state to an idle state. By releasing the dedicated cell-selection information 306, the UE 110 performs a future cell-selection procedure without relying on the dedicated cell-selection information.

Abstract: A tracking system can provide smart alerts based on a user's location. The tracking system can receive a location of a user's mobile device and establish a geographic boundary around the location if the mobile device remains at the location for a threshold amount of time. The tracking system can receive a new location of the mobile device outside of the geographic boundary and configure the mobile device to scan for a tracking device associated with the user for an interval of time. If the tracking system detects the tracking device within the interval, the tracking system stores information indicating that the user possesses the tracking device. Otherwise, the tracking system sends an indication to the mobile device indicating that the user has left behind the tracking device.
