Embodiment one
As shown in Figure 1, the embodiment of the invention provides a kind of method of Cell searching, comprising:
Step 11:, determine the frequency of at least one high RSSI value from high to low according to the ordering relation from high to low of the received signal intensity indicating RSSI value of each frequency in the frequency range.
The RSSI value of general place, sub-district frequency (being working frequency points) will be higher than the RSSI value of other idle frequency (being the inoperative frequency), so, ordering relation from high to low according to the RSSI value of each frequency in the frequency range, determine the frequency of high RSSI value from high to low, like this, in the search cell process, the frequency of the high RSSI value of first search, working frequency points that can place, easier discovery sub-district, thus the speed of search cell improved.
The frequency of high RSSI value can be for one or more.When the frequency of high RSSI value is one, can be the highest frequency of RSSI value in the frequency range, perhaps inferior high frequency, or the like.When the frequency of high RSSI value when being a plurality of, can be ordering from high to low according to the RSSI value, continuous a plurality of frequencies, perhaps discontinuous a plurality of frequencies, or the like.
Step 12: according to the frequency of high RSSI value, determine at least one adjacent frequency of frequency of high RSSI value, obtain the search frequency group of the frequency of high RSSI value.
Because the frequency of high RSSI value itself also might be pseudo-working frequency points, i.e. Jia working frequency points, and its adjacent frequency might be a working frequency points, therefore frequency and adjacent frequency thereof that can the high RSSI value of first search, avoid missing the working frequency points that may exist, improve the speed of search cell.
Just determine at least one adjacent frequency of frequency of high RSSI value, note, at least one frequency here is a frequency adjacent with the frequency of high RSSI value in frequency range, but not at least one adjacent frequency of frequency of the RSSI value of each frequency ordering back and high RSSI value.And the adjacent left side that comprises is adjacent or right adjacent or the left and right sides is adjacent.As seen, the search frequency group of the frequency of high RSSI value comprises that the frequency of high RSSI value reaches and at least one adjacent frequency of frequency of high RSSI value.
When the frequency of high RSSI value when being a plurality of, with the ordering from high to low of the search frequency group of the frequency of each high RSSI value according to the frequency RSSI value of each high RSSI value, realization begins search from the search frequency group of the frequency of high RSSI value, thereby improves the speed of search cell.
Notice that when frequency range when being a plurality of, search frequency group is to sort from high to low by the frequency RSSI value with all frequency ranges, select the frequency of high RSSI value and some frequencies of being adjacent obtain, the frequency of high RSSI value may appear in any one frequency range.
Step 13: but persistent district searched for according to the frequency of search frequency group.
The frequency of search frequency group comprises frequency and the adjacent frequency thereof of search for high RSSI value, and working frequency points that can easier discovery sub-district avoids missing the working frequency points that may exist, thus the speed of raising search cell.
With reference to figure 3, wherein, the frequency RSSI value of all frequency ranges is sorted from high to low, selecting the frequency of the highest RSSI value is example, describe in detail and how to make up a search frequency group: as, get and 3 adjacent frequencies of the frequency of a highest RSSI value left side, and get and right 4 the adjacent frequencies of the frequency of the highest RSSI value, the frequency of the highest RSSI value and 4 frequencies adjacent with its left adjacent 3 frequencies and the right side are searched for the frequency group as one.When the frequency of high RSSI value when being a plurality of, the search frequency group of the frequency of other high RSSI values can be with reference to realization.
Optionally, but before step 13 according to the frequency search persistent district of search frequency group, can be on historical frequency search cell, historical frequency comprises the frequency at the place, sub-district of the resident mistake of portable terminal.
Why earlier will be in historical frequency search cell; be since portable terminal in start or during off-grid; usually the frequency point information at the place, sub-district of resident mistake before can keeping; so elder generation's search cell in historical frequency; can improve search speed under most situation; faster search can be resident the sub-district, for the user provides preferable experience effect.
Optionally, as shown in Figure 2, the method for embodiment of the invention Cell searching, but after the step 13 according to the frequency search persistent district of searching for the frequency group, also comprise:
Step 21: with the additional search frequency group of each frequency outside the search frequency group in the frequency range as frequency range.
Why also to obtain to replenish the frequency of search frequency group, be because under a few cases, emerging sub-district, neither historical frequency, also not in the search frequency group of high RSSI value, so, frequency outside the search frequency group of high RSSI value in the frequency range is searched for the frequency group as a supplement, avoid falling to the working frequency points that may exist, realize the mechanism that whole frequencies all sort whole frequencies are searched in the frequency range, to improve the speed of search cell.
Step 22: each frequency that will replenish search frequency group sorts from high to low according to its RSSI value.
Replenish each frequency of search frequency group, sort from high to low according to RSSI value, like this, in the search cell process, the frequency of the high RSSI value of realization first search, working frequency points that can easier discovery sub-district, thereby the speed of raising search cell.
