Method and system for upgrading and repairing wireless terminal equipment

Abstract

The invention provides a system and a method used for updating and repairing wireless terminal equipment; the system is respectively connected with a computer and a wireless terminal by a download plate and is used for completing the update and download of the software by automatically selecting communication protocols according to the state of the wireless terminal; the method comprises the steps as follows: the state of the wireless terminal is judged according to whether the wireless terminal reverts data or not; when the wireless terminal reverts data packets to a computer, the software of the computer side automatically opens USB and UART passages by a download control module on a download plate so as to carry out the download; when the wireless terminal does not revert data packets to the computer, the download plate control module completes the conversion from USB and UART signals to JTAG protocols, and uses the JTAG protocol to download; the system and the method achieves the download by automatically selecting protocols and the restoration of the wireless terminal, leads to no worry about the shutdown problem during the updating process of the wireless terminal, greatly improves the efficiency of the updated version, and achieves the automatic update and restoration of the wireless terminal.

Description

technical field [0001] The invention relates to the technical field of electronic communication, especially the field of wireless communication, and proposes a method and system for upgrading and repairing wireless terminal equipment. Background technique [0002] With the continuous development of mobile communication technology, the number of global digital mobile users has reached 1.3 billion, and this number is expected to double in the next few years; at the same time, the user's demand for wireless terminals is also increasing sharply, and the competition in the wireless terminal market It is also getting more and more intense. In order to cope with the supply pressure, wireless terminal manufacturers are required to continuously shorten the wireless terminal research and development cycle, and often need to upgrade the software of a large number of wireless terminals to meet the new needs of customers. The efficiency of its software upgrade and download has become an...

Problems solved by technology

[0003] In the prior art, most of the physical connection methods of wireless terminals adopt Universal Serial Bus (USB) mapping as a serial device interface for data communication with a computer, or UART (Universal Asynchronous Receiver Transmitter, Universal Asynchronous Receiver Transmitter) mode for downloading; conventional version USB mode and The advantage of downloading in UART mode is that the download speed is fast, the operation is simple, and it is easy to implement, but the disadvantage is that once the crash problem caused by the wrong version, etc., it cannot be automatically repaired. Only through JTAG (Joint Test Action Group; Joint Test Action Group; ) protocol download, the JTAG download method is generally used to repair the wireless terminal crash problem caused by the wrong version of the wireless terminal software, the disadvantage is that the download speed is slow
