Abstract
A method for controlling effective communication distance based on an RF SIM card comprises the following steps: setting up an RF (radio frequency) parameter corresponding list of a mobile communication terminal, and reading IMEI number of the mobile communication terminal equipped with the RF SIM card under the control of a central processing unit CPU of the RF SIM card to determine the type of the mobile communication terminal; looking for RF parameters corresponding to the mobile communication terminal in the RF parameter corresponding list of the mobile communication terminal, and invocating the RF parameters; and prompting a user to check the RF parameters of no RF parameters corresponding to the mobile communication terminal are found in the RF parameter corresponding list of the mobile communication terminal. According to the method, the RF effective communication distances of different mobile communication terminals equipped with the RF SIM card are substantially equal to each other. The RF parameters of the RF SIM card can be updated automatically even if the mobile communication terminal is replaced, thereby effectively obviating the occurrences of misreading, reading error and reading failure of the RF SIM card, and facilitating use of the users.
Description
Technical field
The present invention relates to be built in mobile communication terminal and have the radio-frequency (RF) signal strength control method of the SIM card of radio-frequency receiving-transmitting interface, particularly relate to and control radio-frequency (RF) signal strength, so that the roughly the same method of radio frequency effective communication distance of described each terminal according to mobile communication terminal.
Background technology
The subscriber identity module Subscriber Identity Model card of existing mobile communication technology is called for short SIM card, is widely used as the customer identification device of mobile communication terminal.Along with scientific technological advance, in the SIM card card body of common mobile communication terminal, increase various smart circuit modules by the whole bag of tricks, make SIM card through described transformation except basic SIM card function is arranged, also have other to be close to the function of life more, radio-frequency SIM card is exactly an example wherein.
Described radio-frequency SIM card is the SIM card that the wireless radiofrequency communication function is arranged, and comprises the integrated circuit in card body and the card body.Be provided with on the described card body can with the interface of mobile phone SIM card seat coupling, integrated circuit in the described card comprises central processor CPU, the radio-frequency SIM card memory, radio-frequency (RF) transmit-receive circuit and the interface circuit that are electrically connected with this central processor CPU, and the radio-frequency receiving-transmitting antenna that is electrically connected with radio-frequency (RF) transmit-receive circuit.By the interface on interface circuit and the radio-frequency SIM card body, described radio-frequency SIM card is electrically connected with mobile communication terminal.Described radio-frequency SIM card can with mobile communication terminal address realizing the standard feature of conventional SIM card, also can communicate by letter with supporting peripheral processor in short distance with the radio-frequency receiving-transmitting antenna simultaneously by radio-frequency (RF) transmit-receive circuit.Above-mentioned Content of Communication and process are specifically handled by the central processor CPU in this radio-frequency SIM card, and described in case of necessity central processor CPU sends to mobile communication terminal by the data wire on the mobile communication terminal SIM card seat, with standard agreement and instructs the screen display and the keyboard that go to control this mobile communication terminal to import.The SIM card development kit SIM Card Tool Kit of described radio-frequency SIM card is called for short the STK technology, realizes by the small-sized programming software that is solidificated in this radio-frequency SIM card, for the value-added service of radio-frequency SIM card provides a development platform simple to operation.The contribution of described STK technology makes in the radio-frequency SIM card that design function is abundant, menu simple to operate becomes possibility, and the user can carry out data input and menu operation to radio-frequency SIM card by visual, interactively means.Described radio-frequency SIM card is used for mobile phone more, remove all functions that possess conventional SIM card, also can allow mobile phone have function concurrently such as smart cards such as transit riding card, gate inhibition's visa card, credit card, small amount payment card, attendance cards, and the information that produces in the described various smart card use can directly show that on the screen of mobile phone the user finishes operations by the keyboard of mobile phone.
When described radio-frequency SIM card uses as smart cards such as transit riding card, gate inhibition's visa card, credit card, small amount payment card, attendance cards, for fear of misreading the card operation and mispronouncing the card operation, the mobile communication terminal that this radio-frequency SIM card is installed leaves the distance of card reader, be the radio frequency effective communication distance, must limit within the specific limits.Under the certain situation of the radio-frequency receiving-transmitting power of radio-frequency SIM card, described radio frequency effective communication distance is influenced by the shield effectiveness of mobile communication terminal.The shield effectiveness of described mobile communication terminal is mainly determined by the material and the manufacturing process of its shell.The radio-frequency receiving-transmitting power of described radio-frequency SIM card is by the radio frequency parameter decision of its setting.For a radio-frequency SIM card of setting radio-frequency receiving-transmitting power, if this radio-frequency SIM card is installed in the mobile communication terminal of shield effectiveness difference, its radio frequency effective communication distance can be distant, have in addition can reach about 1 meter, cause easily and misread card and mispronounce card; If described radio-frequency SIM card is installed in the good mobile communication terminal of shield effectiveness, its radio frequency effective communication distance is just very near, have in addition can not receive and dispatch radiofrequency signal at all, cause not Card Reader phenomenon.For avoiding taking place above-mentioned disadvantage, the user is before using radio-frequency SIM card or when changing mobile communication terminal, must proofread again the radio-frequency receiving-transmitting power of radio-frequency SIM card to service network, promptly the radio frequency effective communication distance of mobile communication terminal that radio-frequency SIM card is installed is proofreaded again, this check and correction process is comparatively complicated, causes very big inconvenience for user's use.Raising along with living standards of the people, the situation that the user need change mobile communication terminal often occurs, therefore make radio-frequency SIM card change its radio frequency parameter setting according to the different mobile communication terminal automatically, this radio-frequency SIM card is installed in all has roughly the same radio frequency effective communication distance will seem especially important in the different mobile communication terminals.
