<p>A method for data transmission in the field of communications, comprising: receiving, by a device, a paging message, and determining an opportunity for acquiring an uplink transmission resource, by basing on a subframe for receiving the paging message; acquiring, by the device, an uplink transmission resource at the opportunity for acquiring the uplink transmission resource; and reporting, by the device, user data in the uplink transmission resource, by using a time advance that is stored in the device itself and that corresponds to a current position. The embodiments of the present invention provide a device for data transmission. According to the embodiments of the present invention, no random access is required when the MTC device transmits uplink data, and no RRC connection or user plane bearer is to be established, which greatly simplifies the procedures of data transmission for the device, and the device can quickly and high-efficiently transmit uplink data, thereby improving the transmission efficiency, and reducing the signaling load of the base station.</p> |
