Abstract: The present disclosure relates to apparatus, methods, and systems for cell selection. One example method includes measuring a received signal communication parameter value of a first cell, determining whether the communication parameter value is greater than a first threshold, if the communication parameter value is less than or equal to the first threshold, obtaining a second threshold, determining whether the communication parameter value is greater than the second threshold, and if the communication parameter value is greater than the second threshold, setting the first cell as a serving cell of a terminal device.

Abstract: A subframe processing method and device are disclosed. A terminal can determine a special subframe in a non-contiguous secondary carrier according to a maximum continuous channel occupancy duration and a channel listening duration of the non-contiguous secondary carrier, and a channel occupancy start reference time point and/or a channel listening start reference time point of the non-contiguous secondary carrier that are obtained, where the special subframe includes all or some gap symbols occupied by the channel listening duration, use all symbols except the gap symbols in the special subframe as symbols that can be occupied by a PDCCH and/or a PDSCH, and correspondingly receive or decode the PDCCH and/or the PDSCH in the special subframe according to the symbols that can be occupied by the PDCCH and/or the PDSCH.

Abstract: An interference cancellation method and device are disclosed. In a process of performing cell reestablishment or cell handover, for any interference cancellation parameter previously received from a network-side device, a user terminal can continue to apply the interference cancellation parameter to perform an interference cancellation operation according to a specified first interference cancellation parameter application rule or first instruction information delivered by the network-side device, or release or no longer apply the interference cancellation parameter. In this way, a currently existing problem that a user terminal cannot know how to process a previously received interference cancellation parameter in a process of performing cell reestablishment or cell handover can be resolved, and further, an objective of improving an interference cancellation effect can be achieved.

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 disclosure provide a method and an apparatus for paging a user equipment. A paging message sent by an MME is received, where the foregoing paging message includes indication information of a UE type; a scheduling resource for sending a paging message of the foregoing UE type is determined according to the indication information of the UE type; and the paging message of the foregoing UE is sent on the scheduling resource, thereby reducing impact on a conventional type of UE that is caused by a limitation on a bandwidth of a received signal of a special type of UE.

Abstract: A method, an apparatus, and a system for implementing alarm event handling. The method includes: acquiring, by a first NodeB eNB, alarm event EM information reported by a user terminal UE; sending, by the first eNB, an EM notification that includes the EM information to at least one eNB that needs to be notified of the EM information, so that the at least one eNB sends the EM notification to a UE of the at least one eNB; and sending, by the first eNB, the EM notification that includes the EM information to a UE of the first eNB. By using the method, the apparatus, and the system according to the embodiments of the present invention, a signaling interaction process for alarm event handling in an emergency case is shortened, thereby greatly shortening a communications delay of a cellular network communications system and greatly reducing system load.

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.
