Abstract: Embodiments of the present invention provide a data transmission method, device, and system. A terminal device determines whether a data volume of uplink data to be sent is less than a preset data volume threshold. If the data volume of the uplink data to be sent is less than the preset data volume threshold, the terminal device establishes an RRC connection to a base station and sends an RRC connection completion message that carries the uplink data to the base station, so that the base station sends the uplink data to an MME by using a signaling message between the base station and the MME. The MME further sends the uplink data to a corresponding application server by using a signaling message between the MME and a P-CSCF.

Abstract: The user equipment (UE) and the Mobility Management Entity (MME) in an evolved 3GPP system generate authentication material that can be carried inside a packet switched network temporary mobile station identifier (P-TMSI) signature field of a Universal Mobile Telecommunications System (UMTS) signaling message from the UE to a UMTS/GPRS serving GPRS support node (SGSN) in a UMTS or GPRS Terrestrial Radio Access Network (UTRAN) or in a GSM/Edge Radio Access Network (GERAN), as well as from the SGSN to the MME of the evolved 3GPP system. The MME authenticates a context transfer request from the UTRAN/GERAN system based on the transferred authentication material and knowledge of how to create or to verify the authentication material. Additionally, the MME and the UE derive or verify authentication material, based on at least one user-specific key, for embedding in the P-TMSI signature field in legacy 3GPP signalling.

The service response method includes: receiving, by a user equipment, downlink data or a downlink message, where the downlink data or message is small-packet data; selecting a signaling mode or data mode as a mode of responding to the downlink data or message; and responding to the downlink data or message by using the selected mode. The technical solutions provided in the present invention are applicable to a scenario where a UE responds to a service.
