Disclosed are various embodiments for on-demand application-driven network slicing. In one embodiment, it is determined that an application implemented in a particular computing device has an increased quality-of-service requirement in order to send or receive data via a communications network. The increased quality-of-service requirement is greater than an existing quality-of-service provided to the application by the communications network. The application sends a request that causes capacity in a network slice having the increased quality-of-service requirement in the communications network to be allocated for the application. The data is transmitted to or from the application using the network slice.

A user equipment transmits user equipment information, associated with a communication of the user equipment, to permit a base station to select a first bandwidth part, a second bandwidth part, or a third bandwidth part. The user equipment is configured to communicate by the first bandwidth part, the second bandwidth part, and the third bandwidth part. The user equipment receives, from the base station, an instruction to monitor the first bandwidth part, the second bandwidth part, or the third bandwidth part. The instruction is selected based on the user equipment information. The user equipment monitors, based on the instruction, the first bandwidth part, the second bandwidth part, or the third bandwidth part.

A first distant apparatus performs communication of streaming data and other data for which a change in data transfer rate is required to be suppressed, and a second distant apparatus performs communication of phone book data and other data for which a change in data transfer rate is permitted. When communication with the first distant apparatus and communication with the second distant apparatus are concurrently performed, a first communication unit is selected for communication with the first distant apparatus and a second communication unit, which is faster than the first communication unit, is selected for communication with the second distant apparatus. Thus, it is possible to make a collision in communication less likely to occur, and to maintain the communication quality of the first type of data.

This application provides example methods, systems, and devices for performing charging on a network resource. One example method includes sending, by a network slice charging function device, a first message to a network slice management function device, where the first message includes an identifier of a network slice instance and filtering information, the filtering information indicates the network slice management function device to send a value that is of a network slice performance indicator of the network slice instance and that matches the filtering information, and the network slice performance indicator describes network performance of the network slice instance. The network slice charging function device can then receive a second message from the network slice management function device, where the second message includes the value. The network slice charging function device can then perform charging on the network slice instance based on the value.

In a communication system having a plurality of user equipment (UE) devices that are operating in a contention based mode for device-to-device (D2D) communication, each UE device transmits a preferred transmission indicator when a condition for preferred transmission is met at the UE device. If a UE device receives a preferred transmission indicator, the UE device delays transmission of a D2D scheduling assignment (SA) to contend for communication resources for D2D communication. The length of the delay can be based on a number of preferred transmission indicators that are received. The preferred transmission indicator is based on a buffer size in one example.

A cell selection method, related to the communications field, includes a terminal device sending a first request to a network device, where the first request is used to request to select a serving cell for the terminal device in an energy efficiency first manner. The terminal device sends first information to the network device, where the first information is used by the network device to select a cell in a first communications system or a cell in a second communications system for the terminal device. The terminal device receives configuration information of a serving cell from the network device, where the serving cell is selected by the network device from the cell in the first communications system or the cell in the second communications system in a manner that energy efficiency of the terminal device is first.
