Abstract: This application provides a transmission mode switching method and an apparatus. When UE is in a connected state, if an uplink service volume of the UE within a first detection time is less than a first threshold, the UE switches a state from the connected state to an ecology conservation optimization; or switches, in the connected state, a transmission mode from an uplink scheduling-based transmission mode to an uplink contention-based transmission mode.

Abstract: A communication method includes receiving, by a terminal device comprising a processor, indication information from a master node. The indication information is used to indicate that a key used for signaling transmission performed between the terminal device and a first secondary node by using a second signaling radio bearer (SRB) is a first key. The first key is used for signaling transmission performed between the terminal device and the master node by using a first SRB. The first secondary node and the master node share one central unit. The communication method also includes determining, by the terminal device, based on the indication information, that the first key is used for signaling transmission performed between the terminal device and the first secondary node by using the second SRB.

Abstract: The present disclosure relates to communication methods and apparatus. On one example method, a terminal device obtains measurement results of N cells, where the N cells include M non-public network cells, where N is an integer greater than or equal to 1, and where M is an integer greater than or equal to 0. The terminal device determines, based on the measurement results of the N cells and measurement result offset values corresponding to H first cells in the N cells, a target cell on which the terminal device is to camp, where H is an integer greater than or equal to 1, and where H≤N.
