Embodiment 1

[0054] refer to Figure 1-2 ,

[0055] When a base station communicates with multiple wireless terminals, take base station A, wireless terminals B, C, and D as an example, after base station A is powered on, it starts continuous reception on the uplink channel, and wireless terminals B and C wake up and start handshaking state, send handshake commands every 500ms;

[0056] After the base station A receives the handshake command sent by the wireless terminal B, C, it sends the base station ID and timing on the downlink channel, and the wireless terminal B, C stops sending the handshake command after receiving the information sent by the base station A, and calibrates its own timing;

[0057] When base station A needs to send a message to the wireless terminal, it broadcasts a downlink command about 1 ms once in the time sequence of 0-10 and 512-522. The downlink command includes the base station ID, timing and command content. Wireless terminals B and C will Start receiving ...

Abstract

The invention discloses a bidirectional communication method of a wireless terminal. The bidirectional communication method comprises the following specific steps: a handshaking stage: realizing timing sequence synchronization; sending a command to the wireless terminal by a base station: broadcasting the command by the base station within an appointed time period, starting receiving by the wireless terminal within the time period, and carrying out timing sequence correction again while receiving; sending a command to the base station by the wireless terminal: broadcasting the command within the appointed time period when an external signal is received by the wireless terminal and a message is required to be sent to the base station, starting the receiving for 2 ms, immediately replying after the command is received by the base station, considering that the command transmission is completed after the command replied by the base station is received by the wireless terminal, and stopping sending and receiving. The bidirectional communication method disclosed by the invention has the advantages of high communication efficiency, low command transmission delay and the like.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a two-way communication method for a wireless terminal. Background technique [0002] Communication base station, also known as wireless base station, refers to a low-power wireless antenna that communicates with user mobile phones. According to the size of its service area and the number of users, the transmission power varies from a few watts to hundreds of watts. Generally, the base station antenna is installed On buildings or towers 15-50 meters above the ground. [0003] The generalized communication base station is the abbreviation of the base station subsystem. Taking the GSM network as an example, it includes base station transceivers and base station controllers. A base station controller can control dozens or even dozens of base station transceivers. In WCDMA, etc. In the system, similar concepts are called NodeB and RNC. [0004] In a narrow sense, a communicati...
