Wireless terminal and remote parameter setting method thereof

The invention provides a wireless terminal and a remote parameter setting method thereof. When a dial-up connection is established by the wireless terminal, a request message to update parameters is sent to a network server by the wireless terminal; equipment information in the request information of the wireless terminal matches with equipment information of a server through the network server; parameter setting information which matches with the equipment information of the wireless terminal is sent; and the parameters are set by using the received parameter setting information through the wireless terminal. The users not only enjoy new function experience brought by technical development, but also do not worry about inconvenience caused by that a wireless router cannot be normally used due to being not familiar with new functions, and further do not worry about complaints from customers or user group churn, which is caused by that the users can not use the terminal for a short time because of updating; and meanwhile, a remote setting function can be simply implanted to all platforms of a data card due to having low relativity with other functions. Furthermore, the remote parameter setting method is simple in operation, and the users can enjoy convenient services.
