Abstract: Embodiments of the present invention provide a random access method and an apparatus. PRACH configuration information of a base station is acquired, and a preamble is sent from a corresponding start PRACH resource, so that access of another terminal device is not affected when the base station identifies an access request of a terminal device that requires coverage enhancement. The solution includes: acquiring at least one group of physical random access channel PRACH configuration information that has been stored, where the at least one group of PRACH configuration information is carried in system information sent by the base station; parsing the at least one group of PRACH configuration information to obtain a corresponding start PRACH resource; and sending a preamble to the base station starting from the start PRACH resource, so that the base station establishes a connection to the terminal device according to the preamble.

Abstract: Embodiments of the present invention provide a core network device, an access network device, and a data offloading method and system, and relate to the field of mobile communications. In the system, the access network device receives an offloading inclination indication of service data from the core network device; the access network device allocates, according to the offloading inclination indication, a transmission resource used for transmitting the service data; and the access network device transmits the service data by using the allocated transmission resource. In the present invention, quality of service (QoS) in the transmission process can be ensured even if data is offloaded by using a first resource such as an unlicensed spectrum, a transmission resource provided by Wireless Local Area Networks (WLAN), or a transmission resource provided by the secondary eNodeB.
