Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine an estimated timing advance (TA) for one or more communications included in a set of communications of a random access channel procedure. The UE may transmit, to a base station, the one or more communications based at least in part on the estimated TA. Numerous other aspects are provided.

A network controller is configured to cause a network to implement a primary network configuration of a network and a secondary network configuration as a backup to the primary network configuration. The network controller may be configured to receive information from a plurality of nodes of a network and information related to the client data to be transmitted through the network. Based on the node information, the network controller is configured to determine available nodes and possible links in the network and then determine a topology of the network. The primary network configuration is determined based on the topology. The network controller then sends instructions to the plurality of nodes of the network to implement the primary network configuration and to switch to a secondary network configuration where a failure of the primary network configuration occurs, wherein the secondary network configuration implements mobile ad-hoc networking in the determined topology.

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.

Devices, systems, and methods are described that employ actionable intelligence in an emergency or other situation requiring immediate situational awareness, based on multiple types of input. Actionable intelligence is an output providing guidance or information that can be acted on to resolve an incident. The device can be configured to request re-allocation of resources based on incident severity, and bonding technology is used to provide improved speed and reliability in networking communications following a triggering event.

There is provided systems and methods for the grouping of UEs, such that UEs can share a UE group context or share a PDU session context or both. In this manner, network resource usage, with respect to UE context and PDU session context management, can be mitigated.

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.

There are provided measures for traffic flow mobility with a single host connection. Such measures exemplarily comprise the definition of a first binding between a set of home addresses of a host and an address of a first interface of a mobile access gateway to a local mobility anchor, the definition of at least one second binding between the same set of home addresses of the host and an address of at least one second interface of the mobile access gateway to the local mobility anchor, and the recording of a mapping between any one of the first and second bindings and traffic flows between the host and the local mobility anchor via a host connection to the mobile access gateway.

A method for receiving a trip path including a plurality of passage places calculated by a server according to an embodiment of the present invention includes the steps of: enabling a terminal to send a request for a trip path including a plurality of passage places to the server, the request containing an indicator for representing the request for the path including the plurality of passage places from the server, wherein if the proposed trip path consists of a plurality of sub-paths, and thus the information of a proposed trip path contains the information indicating the sub-paths of the first sub-path is received through the link for the first sub-path, and the information of the first sub-path may include an indicator indicating whether there exists a second sub-path subsequent to the first sub-path, and a link for the second sub-path.
