A method for congestion mitigation via admission control in a shared-backhaul telecommunications network is disclosed, comprising: assessing a congestion state in a multi-node radio access network having a shared backhaul connection, the congestion state based on congestion of the shared backhaul connection; retrieving an admission control policy based on the congestion state of the shared backhaul connection; performing a policy action of the admission control policy at a first base station acting as a gateway for the multi-node radio access network with respect to the shared backhaul connection; and sending the admission control policy to other nodes in the multi-node radio access network, thereby causing the other nodes to perform the policy action, wherein the policy action is denying a request from a user equipment to attach to the radio access network.

A network data analytics function, which may be implemented as a service, is disclosed which provides a new and improved network data analytics capability in 5G core networks.

An access barring method and apparatus and a communication system. The method includes: performing access barring check or access class determination by UE by using parameters defined for a new radio system. The parameters are applicable to all radio resource control (RRC) states. For different public land mobile networks (PLMNs) and/or network slicing, the parameters are identical or different. With the embodiments of this disclosure, selectable parameters are provided for a uniform access control mechanism defined by an NR system, thereby simplifying an access mechanism, and ensuring all-directional compatibility of a terminal state.

A cell reselection control method according to an embodiment comprises transmitting, by a base station configured to manage a cell having a first coverage and a second coverage as a portion enhanced more than the first coverage, to a radio terminal under the cell, a reselection instruction that instructs to reselect a neighboring cell different from the cell, and reselecting, by the radio terminal, the neighboring cell according to the reselection instruction when the radio terminal is in the second coverage.

A control system enables re-registration of user equipment (UE) on an alternative network in the event of a partial failure of a network (VPLMN) for wireless communication. An access and mobility management function (AMF) manages the communication to user equipment (UE) via network slices (1,2,3). A slice priority management function (SPM) receives data indicative of a change in the network's ability to maintain the instantiated network slices and determines to reduce services via affected network slices. Before said slice reduction, the access and mobility management function is informed and sends a slice reduction message to the user equipment. In the UE an alternate network selection function (ANSF) receives the slice reduction message and selects an alternate network based on the user information (USIM) and the slice reduction information, and triggers registration on the selected alternate network for transferring at least part of the affected services to a network slice of the selected alternate network.

The present invention relates to a communication system which can effectively avoid congestion in ITS communications at a street intersection to properly assist the driving of autonomous vehicles. An information source roadside apparatus 3 acquires terminal movement information on movement directions of nearby pedestrian terminals, and transmits the information to an information destination roadside apparatus, which determines, based on the received information, if there is predicted congestion in the terminal-to-terminal communications at a predetermined future time. When determining that there is predicted congestion, the information destination roadside apparatus transmits an instruction for a congestion avoidance operation to the pedestrian terminals 1. Then, each pedestrian terminal performs the congestion avoidance operation by switching a communication mode from a direct communication mode using the terminal-to-terminal communications, to an indirect communication mode using communications via a roadside apparatus.

Device group partitions and a settlement platform are provided. In some embodiments, device group partitions (e.g., partitions of devices based on associated device groups) are provided. In some embodiments, a settlement platform service is provided. In some embodiments, a settlement platform service is provided for partitioned devices. In some embodiments, collecting device generated service usage information for one or more devices in wireless communication on a wireless network; and aggregating the device generated service usage information for a settlement platform for the one or more devices in wireless communication on the wireless network is provided. In some embodiments, a settlement platform implements a service billing allocation and/or a service/transactional revenue share among one or more partners. In some embodiments, service usage information includes micro-CDRs, which are used for CDR mediation or reconciliation that provides for service usage accounting on any device activity that is desired. In some embodiments, each device activity that is desired to be associated with a billing event is assigned a micro-CDR transaction code, and a service processor of the device is programmed to account for that activity associated with that transaction code. In some embodiments, a service processor executing on a wireless communications device periodically reports (e.g., during each heartbeat or based on any other periodic, push, and/or pull communication technique(s)) micro-CDR usage measures to, for example, a service controller or some other network element for CDR mediation or reconciliation.
