The described technology is generally directed towards a cellular network area optimizer. The area optimizer observes cellular network conditions at multiple radio access network (RAN) nodes within a target area. Based on observed conditions, the area optimizer applies a set of parameter values at the multiple RAN nodes. The set of parameter values enhances the overall throughput, while maintaining or improving connection retainability and accessibility, of the multiple RAN nodes under the observed conditions. The area optimizer learns different sets of parameter values to apply in response to different observed conditions by making parameter value adjustments and observing the effect of the adjustments on overall throughput of the RAN nodes in the target area.

A cell measurement method. According to the method, a terminal device determines that a first cell as a camped cell of the terminal device; and then determines that the terminal device is in a target environment. The terminal device further obtains a signal strength of the first cell and performs a measurement on a second cell when the signal strength of the first cell is less than a first threshold and greater than a second threshold. The second cell determined by the terminal device based on the target environment. The terminal device switches the camped cell of the terminal device from the first cell to the second cell when a measurement result of the second cell meets a handover condition.

A method is disclosed for improved tracking area planning and handling, comprising: assigning a single tracking area code to a plurality of eNodeBs at a messaging concentrator gateway, the messaging concentrator gateway situated in a network between the plurality of eNodeBs and the core network; storing, at the messaging concentrator gateway, at least one indicator of a last known location of a user equipment (UE) other than the single tracking area code; receiving a paging message from the core network at the messaging concentrator gateway for a UE; and performing a paging sequence using the at least one indicator to identify a set of eNodeBs to page the UE, thereby allowing larger tracking area list sizes to be used without increasing signaling traffic between the radio access network and the core network.

The present disclosure relates to a communication technique for fusing, with an IoT technology, a 5G communication system for supporting a higher a data transmission rate than a 4G system, and a system therefor. According to various embodiments of the present disclosure, a method performed by a base station of a serving cell in a wireless communication system may comprise the steps of: transmitting configuration information for an artificial intelligence (AI)-based handover to a terminal; receiving, from the terminal, a handover request to a target cell according to the AI-based handover; and transmitting, to the terminal, a configuration message for access to the target cell, in response to the handover request, wherein the target cell is identified on the basis of a neural network (NN) configured for the AI-based handover and a measurement result of the terminal.

This application discloses a roaming steering method, an apparatus, a device, a storage medium, and a system. In this application, a reference roaming steering condition is determined by an access control device by performing, for a plurality of times, a roaming steering test on one or more terminals belonging to a reference model, and the reference model is a model of a target terminal. Therefore, the reference roaming steering condition is similar to a roaming rule in the target terminal. In this case, when a first access point device obtains the reference roaming steering condition and determines that the target terminal satisfies the reference roaming steering condition, even if the target terminal does not unconditionally obey roaming steering of the first access point device, there is a high probability that the target terminal is successfully steered to roam.

A method and system for controlling air-interface connectivity of a user equipment device (UE). A computing system detects, when the UE has dual connectivity including a first air-interface connection with a first access node and a second air-interface connection with a second access node, and when the first air-interface connection is defined on a first carrier, that the UE is moving toward a geographic area where UEs that were served by the first access node on the first carrier as part of dual connectivity lost their dual connectivity due to their having insufficient aggregate dual-connectivity throughput. And based at least on the detecting, the computing system reconfigures the first air-interface connection of the UE's dual connectivity to be defined on a lower-frequency second carrier, to help avoid having the UE lose its dual connectivity.
