A verification system implements technical solutions for verifying the delivery of messages transmitted by mobile communication systems and the processing of those messages. The message verification system includes a model database and verification processing circuitry configured to receive transmitter route data, receive receiver route data, determine a viewshed for a message, and compare the viewshed to the receiver route data.

Systems and methods are described for assigning a mobility parameter to a wireless device. One or more measurement reports may be collected at an access node from the wireless device. A pathloss change for the wireless device may be calculated based on the collected measurement reports. When the calculated pathloss change exceeds a threshold, the wireless device may be instructed to report surplus transmit power at the access node. The reported surplus transmit power may be correlated to preset location environments and a position of the wireless device classified based on the correlation. A mobility parameter may be assigned for the wireless device.

Provided is a wireless relay device that determines whether or not the wireless relay device has to withdraw from a first wireless multi-hop network to which the wireless relay device itself belong, transmits, in a wireless multi-hop, a request for a connection that uses wireless communication in compliance with a first communication scheme between the wireless relay device and at least one wireless base station, to a wireless base station on the first wireless multi-hop network, according to a result of the determination that the wireless relay device withdraws from the first wireless multi-hop network, and allocates the wireless communication in compliance with the first communication scheme between the wireless relay device and the at least one wireless base station according to a control signal that is transmitted from the wireless base station on the first wireless multi-hop network.

A method and apparatus for reselecting a path for an integrated access and backhaul (IAB) relaying in a wireless communication system is provided. An IAB node configures a criteria of path reselection among multiple nodes, receives information from the multiple nodes, and performs the path reselection based on the criteria by using the information received from the multiple nodes and cell quality of the multiple nodes.

Systems and methods manage split bearer selection in a multi-RAT dual connectivity environment. A first wireless station receives, from a first device, a first signal measurement for the first wireless station and a second signal measurement for a second wireless station. The first wireless station determines that the second signal measurement indicates that a split bearer for the first device can be supported by the second wireless station and identifies, based on the first signal measurement, a distance category for the first device relative to the first wireless station. The first wireless station determines, based on the second signal measurement, whether the second wireless station supports a sustainable split bearer and initiates a split bearer for the first device using the second wireless station, in response to determining that the second wireless station supports the sustainable split bearer.

Methods, systems, and devices for wireless communications are described in which UEs may communicate with satellites and base stations or gateways in a non-terrestrial network (NTN). Due to the large distances between transmitting devices and receiving devices in a NTN, timing adjustments to account for propagation delay communications links via a satellite may include a propagation delay between a UE and a satellite, a propagation delay between a base station and a satellite, as well as a variation in the propagation delays due to movement of the satellite. In accordance with various techniques discussed herein, a UE may account for variation in propagation delay, in addition to determined propagation delay, when determining an uplink timing for uplink communications via a satellite.

A Voice over Internet Protocol (VoIP) server is configured to provide VoIP services to a plurality of VoIP-capable endpoint devices. Geolocation information identifying a first geographic location of the particular endpoint device is received at the VoIP server and from an application running on a VoIP-capable endpoint device. A second geographic location for an IP address is compared to the first geographic location. In response to a mismatch between the compared geographic locations, a location database is modified to include an entry specifying that the particular endpoint device is located at the first geographic location. For an outgoing telephone call from the endpoint device, the modified entry is used to select a telephone carrier. The outgoing telephone call is routed using the selected telephone carrier.

A depth and distance-based single-path routing method, in which location information of nodes in network is gathered after initialization is completed, and a location table of whole-network nodes maintained by the sink node is generated. The update mechanism of the uplink Location frame is switched to a unicast triggering update mechanism to execute a depth and energy-based uplink routing algorithm. For a downlink control packet arriving at a specified ID, location information of a node is obtained through the location table to execute a distance and energy-based downlink routing policy. The distance and energy-based downlink routing policy for a downlink control packet arriving at a specified location and a downlink control packet arriving at the specified ID is executed, and a routing recovery algorithm is executed when an “open area” occurs.
