This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for load balancing network traffic in a wireless network. In one aspect, an access point may determine a plurality of client devices that are associated with an overloaded channel of the wireless network. The access point may identify a first client device of the plurality of client devices based, at least in part, on an airtime consumed on the overloaded channel. The access point may determine one or more alternate paths between the access point and the first client device. The access point may forecast airtime to be used by the first client device on channels of the one or more alternate paths, and steer wireless network traffic of the first client device to a first alternate path of the one or more alternate paths based, at least in part, on the forecasted airtime.

An apparatus, comprising at least one processor, and at least one memory storing instructions, the at least one memory and the instructions configured to, with the at least one processor, cause a network node to transmit a first information to at least one terminal device, wherein the first information characterizes at least one cell and/or frequency of a radio access network notification area, RNA, which is overloaded for at least one slice associated with an existing PDU session of the at least one terminal device.

An information reporting method and device, and a terminal are provided. The method comprises: after detecting that a failure event occurs in a master cell group (MCG) or a failure event occurs in a secondary cell group (SCG), a terminal reports MCG failure information or SCG failure information to a network side, the MCG failure information or SCG failure information being used for network optimization by the network side, wherein the MCG is a cell group of master nodes, and the SCG is a cell group of secondary nodes.

An intent decomposition method includes sending, by a first network device, a first sub-intent target value to a second network device. The method also includes receiving, by the first network device, a first message from the second network device. The first message is used to indicate that the first sub-intent target value is not achieved by the second device. The first message includes a first measurement value of the second network device. The method further includes re-decomposing, by the first network device, an intent based on the first measurement value, and sending first sub-intent target values obtained through re-decomposition to the second network device and one or more other network devices different from the first network device and the second network device until all the first sub-intent target values obtained through re-decomposition are achieved or none of the first sub-intent target values obtained through re-decomposition are achieved.

The performance and ease of management of wireless communications environments is improved by a mechanism that enables access points (APs) to perform automatic channel selection. A wireless network can therefore include multiple APs, each of which will automatically choose a channel such that channel usage is optimized. Furthermore, APs can perform automatic power adjustment so that multiple APs can operate on the same channel while minimizing interference with each other. Wireless stations are load balanced across APs so that user bandwidth is optimized. A movement detection scheme provides seamless roaming of stations between APs.

A method, in a radio communication system, for setup or modification of data flows between user equipment (UE) in dual connectivity with a primary node and a secondary node of the system, comprising switching a data path between the primary node and the secondary node by transmitting message data between the primary node and secondary node to establish a direct user plane path between the secondary node and a serving gateway (S-GW) of the system.

The system obtains a first acyclic graph including multiple nodes and edges connecting the multiple nodes. A process to create a weave of the first acyclic graph produces a matching weave when executed on the first acyclic graph by different computing devices. An addition of a node to the first acyclic graph produces a second acyclic graph. The addition of the node to the first acyclic graph changes the weave of the first acyclic graph. The system obtains a process to reach a global consensus among the multiple computing devices. The process indicates a criterion to satisfy prior to reaching the global consensus and determines whether the multiple computing devices in the network satisfy the criterion. Upon determining that the criterion is satisfied, the system adds a finalize node to the first acyclic graph to obtain a third acyclic graph. A weave of the third acyclic graph cannot change.
