Abstract: The present invention discloses a method, an apparatus, and a system for establishing a device-to-device connection, and relates to the field of communications technologies. The method includes: obtaining, by a device-to-device D2D server, registration information of a first device needing to perform D2D communication; performing pre-matching for the first device according to the registration information of the first device to find a second device; and triggering an evolved Node Base eNB to establish a D2D communication link between the first device and the second device. In the present invention, a D2D server triggers an eNB to establish a direct device-to-device connection between two devices.

Abstract: The invention concerns transfer of payload data via a mobile communications network, wherein a communications terminal is configured to communicate payload data with a communication entity via the mobile communications network, the method comprising: sending, by the communications terminal, a request message, to set up a connection to the network, the request message including information to identify the terminal; including, by the communications terminal, the payload data to be communicated in the request message; and receiving, by the network, the request message in the network and routing at least part of the payload data to the communication entity.
