Abstract: Provided are a system for implementing multiple Radio Access Networks (RANs) convergence and a method thereof. The method includes: an anchor RAN establishes a connection with a User Equipment (UE); the anchor receives a RAB establishment request from a Core Network (CN); the anchor RAN selects an auxiliary RAN; the anchor RAN sends quality of service (QoS) parameters to the auxiliary RAN, so that the auxiliary RAN establishes a connection with the UE according to the QoS parameters, while the anchor RAN keep the connection with the UE. With the methods provided in embodiments for the present disclosure, multiple RANs convergence is implemented, and the UE establishes connections with the anchor RAN and the auxiliary RAN at the same time, so as to improve the peak rate of the UE.

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: The present invention provides an uplink reference signal sending method, and the method includes: sending, by a terminal device, an uplink reference signal on N1 second component carriers within a determined uplink reference signal sending time, and prohibiting, on M1 first component carriers in M first component carriers within the sending time, the terminal device from sending an uplink signal, where the first component carriers are carriers on which scheduling of uplink data transmission is allowed, and the second component carriers are carriers on which scheduling of uplink data transmission is prohibited. N1=M1, in other words, within the sending time, a quantity N1 of second component carriers on which the uplink reference signal is sent is less than or equal to a quantity M1 of first component carriers on which sending of the uplink signal is prohibited.

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.
