Embodiments disclosed include a method for establishing a communication connection. The method includes: receiving a connection request message transmitted by a first terminal, the connection request message carrying a first user identifier and a second user identifier; determining a second relay node corresponding to the second user identifier, the second relay node being a relay node communicatively connected to a second terminal; transmitting the connection request message to the second relay node through a relay path to the second relay node, so that the second relay node transmits the connection request message to the second terminal; and transmitting, in response to receiving a connection confirmation message returned by the second terminal, the connection confirmation message to the first terminal, so that the first terminal establishes a communication connection with the second terminal based on the connection confirmation message.

The present invention belongs to the technical field of organic supermolecules, and specifically discloses a 3,4-ethylenedioxythiophene (EDOT) polymer capable of supramolecular assembly with carbon-based materials, and a preparation method thereof. The polymer of the present invention is a polymer with 3,4-ethylenedioxythiophene-2-acetylene as the main chain and alkoxy as the side chain. The polymer is prepared as follows: subjecting EDOT to bromination, to give 2,5-dibromo-3,4-ethylenedioxythiophene; then reacting 2,5-dibromo-3,4-ethylenedioxythiophene and trimethylsilyl acetylene (TMSA) to give bis(trimethylsilyl)-3,4-ethylenedioxythiophene; removing trimethylsilyl (TMS) protecting groups from the bis(trimethylsilyl)-3,4-ethylenedioxythiophene, and subjecting the obtained compound and 2,5-dibromo-3,4-ethylenedioxythiophene to Sonogashira coupling to give an EDOT polymer. The polymer of the present invention can form a supramolecular assembly system with carbon nanotubes (CNTs), which involves &#x3c0;-&#x3c0; adsorption of the main chain and entanglement of the side chain.

An embodiment of a communication management unit (CMU) includes emulator and data-mining circuits. The emulator circuit is configured to generate a data request having a same format as a data request from a vehicle communications center, to send the data request to a subsystem disposed on a vehicle, and to receive data sent by the subsystem in response to the data request. The data-mining circuit is configured to provide at least some of the received data to a determining circuit configured to determine information in response to the provided data. For example, such a CMU can request flight-plan data from a flight management subsystem (FMS) by sending, to the FMS, an emulated data-request message having the same format as a data-request message from a ground-based aircraft operations center. That is, the CMU can 'fool' the FMS into 'thinking' that the data-request message originated from the ground-based aircraft operations center.
