Please refer to Fig. 5, Fig. 5 is the flow chart 500 of the terminal measurement scheduling method of display according to one embodiment of the invention, describes subscriber equipment according to the quantity N of frequency to be measured (or alien frequencies frequency)
freqthe measuring period of adjustment alien-frequency district.First, this subscriber equipment enters service state and starts to measure (step 502).At this, the service state of this subscriber equipment can be CELL_DCH, CELL_FACH in TD-SCDMA system, CELL_PCH, URA_PCH or idle mode state.Next, in step 504, subscriber equipment obtains the quantity N of frequency to be measured
freq, the quantity N of frequency to be measured
freqcan be the quantity being positioned at all alien frequencies frequencies of frequency list to be measured.At this, the quantity N of frequency list to be measured and frequency to be measured
