Abstract: A registration method applied in a terminal device includes sending a first request, where the first request is used to request to register in a first cell, receiving a first message, where the first message is used to indicate that the terminal device is successfully registered in the first cell, when the first message does not carry a first network slice identifier and the terminal device cannot establish a protocol data unit (PDU) session on a first network slice corresponding to the first network slice identifier, sending a second request, where the second request is used to request to register in a second cell, receiving a second message, where the second message carries a second network slice identifier, and establishing the PDU session on a second network slice corresponding to the second network slice identifier.

Abstract: This application relates to a network device transmission bandwidth reduction method and related device for reducing a transmission bandwidth of a network device, thereby reducing power consumption and battery life of terminal devices. In one embodiment, a terminal receives transmission bandwidth reduction configuration information sent by a network device, where the transmission bandwidth reduction configuration information includes a set of transmission bandwidth reduction parameters supported by the network device. In response, the terminal sends a target transmission bandwidth reduction coefficient to the network device, where the target transmission bandwidth reduction coefficient is a transmission bandwidth reduction coefficient of a serving cell expected by the terminal. A serving cell is one or more cells that currently provide services for the terminal. In this way, the network device reduces a transmission bandwidth of the serving cell based on the target transmission bandwidth reduction coefficient reported by the terminal.
