Abstract: A method includes: sending, by a first network device, a first configuration message to a terminal device, where the first configuration message is used to instruct the terminal device to configure a second ciphering/deciphering function associated with a second network device and share a first data packet numbering/reordering function, and the terminal device is configured with the first data packet numbering/reordering function and a first ciphering/deciphering function associated with the first network device; and receiving, by the first network device, a first configuration complete message sent by the terminal device. In this embodiment, the first configuration message is used so that the terminal device may configure the function associated with the second network device. Therefore, during handover, the terminal device may simultaneously perform data transmission with the second network device and the first network device, to reduce or avoid a service interruption time caused by handover.

Abstract: A user equipment obtains configuration information used to detect a received signal strength indicator (RSSI) value of a signal on an unlicensed frequency, samples the signal on the unlicensed frequency at a sampling interval included in the configuration information to obtain RSSI values of the signal on the unlicensed frequency sampled at sampling moments. The user equipment determines statistics on the RSSI values of the signal on the unlicensed frequency within a statistical window, obtains an RSSI value statistical result of the signal on the unlicensed frequency based on the statistics, and reports the RSSI value statistical result to a base station.

Abstract: A measurement configuration method and an apparatus are provided. The method includes: A network device sends first information to a terminal device. The first information includes configuration information of an SCC. The network device sends second information to the terminal device. The second information includes configuration information of a first measurement window, and the second information is used to enable the terminal device to switch, when supporting CA, from performing cell measurement in a measurement window-free measurement manner to performing cell measurement by using the first measurement window. A carrier included in the CA includes the SCC configured based on the first information. According to the foregoing method, after the network device configures the SCC, the terminal device may switch, based on the second information, from performing cell measurement in the measurement window-free measurement manner to performing cell measurement by using the first measurement window.

Abstract: This application provides a communication method and a communications apparatus. A terminal in an inactive state receives a paging message, and content in the paging message is determined. When the content includes a first identity of the terminal, the terminal sends a first request message to a first access network device, where the first request message carries a non-access stratum (NAS) identifier of the terminal. When the content includes a second identity of the terminal and an identity of an anchor access network device, the terminal sends a second request message to the first access network device. The communication method of is application can adapt to a communication requirement of a terminal in an inactive state.

Abstract: Methods, systems, and apparatus for communications are provided. In one aspect, a communication method including: determining, by a first communications apparatus, buffer latency information, and sending, by the first communications apparatus, the buffer latency information. The buffer latency information is determined based on a buffer latency of one or more data packets. The buffer latency indicates one of a time interval between a time point at which a data packet arrives at an access stratum (AS) and a time point at which a corresponding buffer status report (BSR) is sent, or a time interval between a time point at which a data packet arrives at an AS and a time point at which a corresponding uplink grant is received.
