Problems solved by technology

However, reducing the connection distance between wireless terminals limits the range of use of wireless terminals
In order to increase the connection distance between wireless terminals and expand the use range of wireless terminals, in actual design, it is often necessary to design excess transmission power for wireless terminals or increase the modulation bandwidth of wireless terminals to improve the transmission and reception capabilities of wireless terminals. To ensure effective interconnection within the specified operating distance, this will inevitably increase the production cost of the wireless terminal itself and waste a lot of network resources

Embodiment Construction

[0027] The core content of the present invention is: by utilizing the idle resources of the wireless terminals irrelevant to the current communication in the existing network resources, make them perform wireless relay, successfully establish the communication link between the terminals that require communication, and assist the terminals to carry out information transmission.

[0028] As shown in FIG. 3 , FIG. 3 is a schematic diagram of information transmission implemented by a calling terminal and a called terminal using a wireless terminal. In FIG. 3, the calling terminal requests to establish a communication link with the called terminal for information transmission. Because one of the calling terminal and the called terminal is located in an area with poor wireless network signal coverage, or because the distance between the calling terminal and the called terminal is too far, beyond the effective connection distance between the two, the calling A communication link can...

Abstract

The method includes following steps: the calling terminal sends out a signal of seeking help to ask other wireless terminal in the system to assist the calling terminal in making communication with the called terminal; b) other wireless terminals in the system receives the signal of seeking help, and after confirming the its own capability of providing the help in making forwarding between the calling terminal and the called terminal, they request for providing help for the data transmission between the calling terminal and the called terminal; c) after confirming the calling terminal accepts the help, the other wireless terminal allocates the time slot for the communication link between the calling terminal and the called terminal; the data transmission is made between the calling terminal and the called terminal through the allocated time slot.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method for realizing information transmission. Background technique [0002] When information is transmitted between wireless terminals, the transmitted information may include voice information or data information. In the prior art, no matter whether the information to be transmitted is voice information or data information, it is necessary to establish a communication link between wireless terminals for two-way data transmission. [0003] When transmitting voice information, it is necessary not only to send the voice information of the own party to the other party, but also to receive the voice information of the other party, so two-way data transmission is required between wireless terminals. During the transmission of data information, due to the existence of interference and fading, bit errors will generally occur in the process of data information transmis...
