Abstract: A communication method and a device are described to compress and decompress a data packet including an ethernet header to reduce radio transmission resources of an air interface. The communication method includes determining, by a sending device, a to-be-sent data packet. The to-be-sent data packet is a data packet including an ethernet header. The method further includes determining, by the sending device, a field to be compressed in the header of the to-be-sent data packet; and compressing, by the sending device, the header of the to-be-sent data packet according to a preset method. The preset method includes: removing the field to be compressed from the header of the data packet, or replacing the field to be compressed with a corresponding short field; and sending, by the sending device, a data packet obtained after the compressing.

Abstract: Embodiments of this application disclose a service paging method, a related device, and a system. The method may include: When a core network device and an access network device perform multicast and broadcast service paging on a terminal device, update and/or security processing are/is performed on an identifier used to identify a multicast and broadcast service each time. The terminal device can determine the multicast and broadcast service based on the identifier on which update and/or security processing are/is performed. In embodiments of this application, the identifier on which update and/or security processing are/is performed is used during multicast and broadcast service paging. In this way, difficulty of tracking the multicast and broadcast service by an eavesdropper can be increased, to improve security of the multicast and broadcast service.

Abstract: Disclosed are a signaling optimization method and device, to resolve a problem of heavy signaling overheads and long data transmission delay when a user equipment (UE) accesses a network side. The method includes: receiving, by the UE, configuration information sent by a first network side device, where the configuration information includes a list, and the list is a cell list or a base station list; and entering, by the UE, an intermediate state according to the configuration information, where the intermediate state means that: when the UE stores context information of the UE, if the UE moves and a cell movement range falls within a coverage area of a cell or a base station included in the list, the UE performs cell reselection according to the list. Embodiments of the present disclosure are applicable to optimization of signaling transmission between the UE and a network side.
