Abstract: A secondary cell group (SCG) side service processing method includes a master base station that configures a master cell group and an SCG for a terminal device. In uplink and downlink data transmission processes, when link quality information of a serving cell in the SCG meets a first preset condition, the terminal device obtains link quality information of a neighboring cell of the serving cell, determines, based on the link quality information, whether there is a better neighboring cell, and when there is no better neighboring cell, sends a first message to the master base station to enable the master base station to determine, based on the first message, whether to release the SCG.

Abstract: A communication method and device determines information of a data packet that fails to be transmitted in a first QoS flow. Some or all of the data packet that fails to be transmitted is discarded, and a sequence number is reset for an unsent data packet, so that the sequence number of the unsent data packet and a sequence number of a successfully sent data packet are consecutive. If the first QoS flow includes a data packet that fails to be transmitted, some or all of the data packet may be discarded. This is equivalent to skipping retransmitting a discarded data packet.
