The present invention relates to a method and device for distributing idle UE by a carrier in eNB of a multi-carrier based mobile communication system. The method of distributing idle UE in a multi-carrier based mobile communication system according to the present invention includes a process of determining a search rate by a carrier on the basis of information representing load on the carrier, a step of determining a cell reselection priority on the idle UE on the basis of the determined search rate, and a process of transmitting the determined cell reselection priority to the idle UE.

There is provided mechanisms for load balancing data traffic between at least two carriers in a communications network supporting the at least two carriers. A method is performed by a system. The method comprises obtaining current channel quality information for a wireless device of the at least two carriers. The method comprises predicting a future volume of a data flow of the wireless device. The method comprises determining whether to offload the wireless device to a second carrier of the at least two carriers or not according to the current channel quality information and the predicted future volume.

Automated offloading of subscribers in a system having a set of mobility management entities (MMEs) during mobility management equipment failures is provided. Each MME maintains performance status and location information about all MMEs. When an MME senses performance degradation the traffic directed to that MME is allocated among the remaining MMEs in the set.

A satellite communication method and a network device are disclosed. A first network device learns of traffics of a plurality of satellite communications link or air interface resources allocated to a plurality of satellite base stations. The first network device sends identification information to a second network device, where the identification information indicates that a traffic of a satellite communications link reaches a specified threshold, or that an air interface resource allocated by a ground station to a satellite base station reaches a specified threshold. The second network device receives an identifier message, determines a to-be-linked satellite base station that has an idle resource, and sends, to the to-be-linked satellite base station, a second message including information about a generated beam of the to-be-linked satellite base station.

A method is for redirecting data traffic destined for user equipment in a cellular network with packet data convergence protocol function local to connection points of the cellular network. The method includes obtaining a prefix and identifier for the user equipment, configuring a secondary connection point to provide a prefix of a primary connection point, the identifier for the user equipment and radio bearer information for the user equipment, and redirecting data traffic for the user equipment to the secondary connection point using network address translation to utilize a prefix of the secondary connection point and the identifier of the user equipment as the destination address for the data traffic.

A method and communication system has been developed to increase the number of messages sent over a bandwidth limited channel and/or under noisy conditions by using a variable message length encoding and decoding scheme. With this technique, the messages having a higher probability of being sent are shorter as compared to the messages that are less likely to be sent under the current conditions. With this technique, a higher number of transactions per unit of time can be communicated and/or executed over a given bandwidth limited channel. When the transmitted message is received, the receiver does not know the message length, but the receiver deduces the length by using information from various error detection and correction techniques, such as forward error correction (FEC) and cyclic redundancy check (CRC) techniques.

Systems and methods relate to a Self-Organizing Network (SON) that makes changes to operating parameters for the purpose of load balancing, to increase data communication throughput and capacity. A device may determine load balancing ratios and unused throughput for a first frequency band and a second frequency band for a cell site. The device may also determine, based on the load balancing ratios and the unused throughputs, whether a load balancing procedure for the cell site should be performed to increase a traffic throughput at the cell site.

Embodiments are directed towards providing 5G zero touch traffic management of cells in a network. A target cell associated with a network objective is identified. One or more neighbor cells are also identified. Transmit power and tilt capabilities of the target cell are determined. An interference between the target cell and the one or more neighbor cells is also determined. An electrical antenna tilt adjustment or a transmit power adjustment is determined for the target cell to apply based on the transmit power capabilities, the tilt capabilities, the interference, and the network objective. The determined electrical antenna tilt adjustment or the determined transmit power adjustment are then provided to the target cell. If the network objective is met after the target cell applies the electrical antenna tilt adjustment or the determined transmit power adjustment, then the changes are confirmed, otherwise they are reversed.

A method and system for controlling uplink communication from a user equipment device (UE) that has at least two co-existing air-interface connections including a first air-interface connection with a first access node and a second air-interface connection with a second access node. An example method includes comparing a level of antenna pattern efficiency associated with the first air-interface connection with a level of antenna pattern efficiency associated with the second air-interface connection and, based at least on the comparing, configuring an uplink split ratio defining a distribution of uplink user-plane data flow of the UE between at least the first air-interface connection and the second air-interface connection. In an example implementation, this could involve configuring one of the air-interface connections as a primary uplink path to which the UE restricts its uplink communication unless and until a trigger occurs for transitioning the UE to operate in an split-uplink mode.

Embodiments of this application provide a beamforming method and apparatus, a radio access network device, and a readable storage medium. In this method, feature data is first obtained, and the feature data includes at least one of feature data of a terminal device and feature data of a cell, where the feature data of the terminal device is used to represent azimuth information of the terminal device, and the feature data of the cell is used to represent load information of the cell and distribution information of the terminal device. After the feature data is obtained, a beamforming parameter is obtained based on the feature data and a machine learning model, where the beamforming parameter includes at least one of a beam direction, a beam width, and a quantity of beams. After the beamforming parameter is obtained, beamforming is performed on a to-be-sent signal based on the beamforming parameter.
