Abstract: A terminal receives configuration information from a first access network device. The configuration information includes a paging area information that indicates a paging area for the terminal in a first mode. In the first mode, the terminal sends a first message to a second access network device when the terminal is in a cell that does not belong to the paging area. The first message includes a paging area update indication. The terminal then receives a connection establishment indication from the second access network device, and establishes a connection between the terminal and the second access network device. The terminal sends a second message to a core network device using the established connection between the terminal and the second access network device, the core network device releases a connection between the first access network device and the core network device established for the terminal in response to the second message.

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.
