Abstract: A communication method, apparatus, and system. Through capability exposure of a radio access network device, the radio access network device may obtain a congestion parameter of a radio access network based on indication information, to determine whether congestion occurs in the radio access network. In addition, the radio access network device may send the congestion parameter to a proxy entity. The proxy entity may identify the congestion parameter of the radio access network, so that congestion control on a wireless network can be optimized.

Abstract: The disclosure provides an on-board charger control system and method.

Abstract: An isolated bi-directional DC conversion circuit and a method for controlling the same are provided. The DC conversion circuit includes a transformer with a first energy storage element and a primary-side rectification bridge coupled to the primary side of the transformer and a second energy storage element and a secondary-side rectification bridge coupled to the secondary side of the transformer. The primary-side rectification bridge consists of multiple first power switching devices. The secondary-side rectification bridge consists of multiple second power switching devices. Each of the multiple first and the second power switching devices have a body diode in inverse parallel connection therewith.

Abstract: A method and an apparatus for discovering an edge application server (EAS) are provided. A session management function (SMF) network element that serves a session of a terminal apparatus obtains information about at least one EAS, or obtains indication information of an EAS that cannot serve the terminal apparatus; and the SMF network element determines first information based on the obtained information, where the first information is used to determine information about an extension mechanisms for domain name system client subnet (ECS) option, or the first information is used to determine an address of a local domain name system (DNS) server, and the information about the ECS option or the address of the local DNS server is used to determine an EAS that serves the terminal apparatus. The first information is determined when the information about the EAS or the EAS that cannot serve the terminal apparatus is considered.

Abstract: A wireless communication method includes: obtaining subnet information of a first subnet corresponding to a first session; receiving a data packet, where the data packet is a multicast packet or a broadcast packet; determining, based on the subnet information, that the data packet corresponds to the first session in the first subnet; and sending the data packet via the first session.

Abstract: A data transmission method includes receiving third information from a session management network element. The third information includes first transmission delay information of data packet transmission between an access network element and a terminal device. The data transmission method further includes determining congestion control parameter information based on the third information, and sending the congestion control parameter information to the data sending network element. The congestion control parameter information is useable to indicate that a data amount of a first service sent by a data sending network element to a second user plane function network element for the first time after a user plane function network element that is configured to serve the first service in the data sending network element is switched from a first user plane function network element to the second user plane function network element.

Abstract: Embodiments of the present disclosure relate to a method, a device, and a computer-readable storage medium for allocating system resources among a plurality of network slices in a communication network. In the communication network, a network device determines utility values of two network slices. A network slice corresponds to a set of network functions of a set of services served thereby. A utility value of the network slice indicates the level of demand for system resources by the set of services associated with the network slice. The network device determines a difference between the utility values of the two network slices. If the difference exceeds a threshold utility value, the network device re-allocates system resources among the plurality of network slices in the communication network.
