Abstract: This application discloses a communication system including a master base station and a secondary base station, both connecting with a terminal. In the communication system, the master base station sends a first message to the secondary base station for allocating transmission resources for one or more flows to be transmitted between the secondary base station and a terminal, wherein the first message carries one or both of: identification information of each flow to be transmitted, and information of a data radio bearer (DRB) associated with each flow to be transmitted, then the secondary base station may determine a mapping relationship between a DRB and an admitted flow according to the first message. Moreover, the master base station sends DRB configuration information to the terminal. Therefore, requirements of 5G communication systems for QoS management of information transmission in a dual connectivity scenario can be met.

Abstract: The present application discloses a wireless local area network access point search method, an apparatus, and a system, relates to the field of communications technologies, and can reduce power consumption for passive scanning. According to the method, beacon sending information of a wireless local area network access point and measurement information of a user equipment are matched, so that the user equipment can search for the wireless local area network access point only at the time when and a frequency channel number at which the wireless local area network access point sends a beacon. Compared with the prior art in which a user equipment needs to continuously keep a state of searching for a wireless local area network access point, the present application greatly shortens time spent by the user equipment in listening to a beacon, and therefore reduces power consumption of passive scanning.

Abstract: The present disclosure relates to the field of mobile communications technologies, and in particular, to an offloading method and an apparatus. In this solution, when a terminal is in a handover process, a destination cellular network node sends, to the terminal, configuration information of a WLAN AP managed by the destination cellular network node; and then the terminal selects a destination WLAN AP from WLAN APs managed by the destination cellular network node, and offloads data of the destination cellular network node to the destination WLAN AP. Therefore, the destination WLAN AP selected by the destination cellular network node can be received before a handover is completed, thereby ensuring service continuity and improving service quality of a terminal.
