Can a Status Flag be set for portable terminal---" moving sign ".As " moving sign " when be wrong (false), the expression portable terminal remains static, and when " moving sign " be correctly when (true), represents that portable terminal is kept in motion.
Step 302: control module periodically reads signal power strength based on the interval of the period of setting, and the signal power strength that reads of each period of buffer memory;
It is pointed out that signal power strength can comprise received signal intensity indication (RSSI, Received Signal Strength Indication).
Step 303: control module is calculated the high-order distance of current period signal power strength;
If that read is RSSI, can utilize following formula to calculate variance D (X) or the mean square deviation Var (X) of each cycle RSSI of buffer memory.
X
iRepresent each value of RSSI constantly, N is a natural number, indication cycle, and D (X) represents the variance of each cycle RSSI, Var (X) represents the mean square deviation of each cycle RSSI.

Signal power strength can comprise RSSI.
Step 310: control module is calculated the high-order distance of current period signal power strength;
Equally, be RSSI as if what read, calculate variance or the mean square deviation of each cycle RSSI of buffer memory.
Step 311: whether control module judges the numerical value that calculates greater than the motion thresholding, if greater than, enter step 312, otherwise, to the transmission of restructural multiaerial system and the last different command information of a period of portable terminal, and return step 301;
If the numerical value that calculates illustrates that greater than the motion thresholding current period portable terminal is kept in motion.Otherwise, illustrate that current period portable terminal remains static, return step 301 and the follow-up period judged continuing, and with the next one period as the current period.
Because under the inactive state, can be reconstructed, therefore, the restructural multiaerial system receives and last different command information of a period, will proceed reconstruct.
Step 312: control module is set to true with " moving sign ", and returns step 301.
