This application is directed to a method and an apparatus for associating an application with a network slice, and a communications system. The method includes: obtaining, by a terminal, display instruction information, an identifier of a first network slice that the terminal is allowed to access, and service feature information corresponding to the first network slice. The method further includes: displaying the service feature information corresponding to the first network slice on a first display interface of the terminal based on the display instruction information, and generating a first network slice selection policy when detecting an operation of associating a first application with the first display interface. The first network slice selection policy can include a mapping relationship between the first application and the identifier of the first network slice corresponding to the first display interface.

A communication device, which complies with an IEEE802.11 standard and performs communication by assigning an Association identifier (AID) to a partner device, determines the AID to be assigned to the partner device from a first range of AID values if the partner device is a first device compatible with a frame that is transmitted with a destination designated by a range of the AID, and determines the AID to be assigned to the partner device from a second range different from the first range if the partner device is a second device not compatible with the frame that is transmitted with the destination designated by the range of the AID.

A framework of abstraction of new and existing 5G radios can enhance capabilities of new and existing micro radios and other short range radio technologies to enable intelligent service delivery, dynamic access learning capability, and network slicing over 5G access networks. Enhancing layer communication for both control and user plane can be tunneled through the hosting layer and exploit a common transport provided by the hosting layer. The tunneling through the hosting layer can also enable the enhance capabilities to access the same radio management functions and can be orchestrated by the same core function. Additionally, provisioning processes can be reduced based on the types of Internet-of-things devices being previously connected to a software-defined networking device.

Embodiments of the present invention provide a frequency reuse method and a related apparatus. The method in the embodiments of the present invention includes: sending, by an access point, a first message to a station, where the first message carries indication information indicating that a basic service set is in a fractional frequency reuse mode; receiving, by the access point, a second message sent by the station, where the second message carries indication information indicating that the station supports the fractional frequency reuse mode; and communicating, by the access point, with the station in the fractional frequency reuse mode after the access point determines, according to the second message, that the station supports the fractional frequency reuse mode. In the embodiments of the present invention, frequency interference in a Wi-Fi network can be effectively reduced.

A search range decision unit (103) first decides, as a narrow-down count, the number of transmission points for which each of user wireless terminals becomes a connection candidate, based on the number of user wireless terminals that perform wireless communication with one of the plurality of transmission points. In addition, the search range decision unit (103) limits, based on combination conditions stored in a storage unit (102), the number of the plurality of transmission points that can be combined with one of the user wireless terminals according to the narrow-down count, and sets combination limitation information that associates the plurality of transmission points with the user wireless terminals that are the connection candidates for each of the plurality of transmission points.

A bridge may include a donor bridge node and one or more service bridge nodes. The donor bridge node may be configured to connect to a base station pooling location comprising a plurality of cell signals, determine for each cell signal a service link carrier frequency in a service link frequency band and a bridge link carrier frequency in a bridge link frequency band, associate each cell signal and the determined carrier frequencies in the service link frequency band and in the bridge link frequency band with the one or more service bridge nodes, and communicate each cell signal at the bridge link carrier frequency of the cell signal. The service bridge nodes may communicate with the donor bridge node at the carrier frequency of the bridge link frequency band and with user equipment in the service link carrier frequency band of the service link frequency band.

The disclosure discloses a method for constructing a TFDMA random self-organizing ad hoc network: the total spectrum bandwidth W is divided into N=W/Δf sub-channels, and Δf represents the bandwidth of one sub-channel. 24 hours a day is divided into U epochs, V time frames, S time slots, and E time chips. In an epoch of sub-channel bandwidth Δf, the last time slot is connected to the first time slot to form a time-frequency loop net. The N epoch-ring net corresponding to the N sub-channels are stacked together in a manner of time slot alignment to form a cylindrical web. A web is reused U times to cover the full spectrum bandwidth W and 24 hours a day, forming a time-frequency division multiple access self-organizing network.
