Abstract: The technology of this application relates to a method for controlling a client to go online, a network device, and a client, and relates to the communications field. The technology provides a method for supporting a network side in controlling a client to retransmit an online request packet. A network device determines a sending interval of an online request packet for a client, and transmits the sending interval to the client by using an advertisement packet, so that the client retransmits the online request packet based on the interval specified by the network side. In this technical solution, the network side changes from passively responding to an online request sending behavior of the client to actively controlling the online request sending behavior of the client.

Abstract: Systems and methods described herein bring a 5G standalone-capable end device back into 5G service to leverage the 5G network's data capacity as soon as a VoLTE call is over. A network device receives a fallback connection, for a 5G New Radio (NR) standalone-capable end device, from a second network to the first network to support a voice call on the end device, wherein the fallback connection supports a voice-over-LTE call. The network device detects an end of the VoLTE call and initiates, in response to the detecting, a handover of the end device back to the second network, wherein the initiating occurs while the end device is in a radio resource control (RRC) connected mode.
