    Abstract: Embodiments of the present invention provide an MTC device communication method, device, and system. A second network element receives, a query message sent by a first network element after the first network element identifies that a type of a received short message is a preset-type short message. The query message comprises an identifier of a receiver of the short message and an identifier of a sender of the short message. The second network element checks whether the sender is authorized to send the preset-type short message to the receiver. The second network element sends a message to the first network element indicating whether or not to send the short message to the receiver.

    Abstract: An access control method, including obtaining, by a protocol-stack upper layer of a terminal, an override identifier, starting, by the protocol-stack upper layer of the terminal, an application specific congestion control for data connectivity (ACDC) check according to a service initiated by the terminal, and, if the protocol-stack upper layer of the terminal confirms that the service initiated by the terminal can pass the ACDC check and determines that the override identifier corresponding to an application identifier of the service passing the ACDC check is overriding an access class barring (ACB) check, sending, by the protocol-stack upper layer of the terminal, an radio resource control (RRC) establishment request message to an access layer of the terminal, where the request message carries an indication of not performing an ACB check.

    Abstract: A data transmission method and a data transmission entity are disclosed. Embodiments include receiving, by a first MTC-IWF entity, first control plane signaling from a first mobility management entity, where the first control plane signaling carries a data packet that is from first UE, and wherein a target UE of the data packet is a second UE, determining, first route information, where the first route information is used for indicating a second network side device that serves second UE and sending, by the first MTC-IWF entity to the second network side device according to the first route information, second control plane signaling carrying the data packet so that the second network side device sends the data packet to the second UE.

    Abstract: The present invention provides a method, an apparatus and a system for device discovery. The method includes: acquiring, by a first device, a user identification of a target user, and acquiring, according to the user identification of the target user, broadcast information of a second device which the target user logs in; when broadcast information of another device is monitored through a D2D function, matching, by the first device, the monitored broadcast information with the broadcast information of the second device, and if the match is successful, determining, by the first device, that the second device and the first device are within a preset distance. According to the present invention, the accuracy of discovering a short distance user is improved and, thus, the problem in the prior art that the accuracy of discovering a user in a short distance cannot be guaranteed by using a cell ID is solved.
