RSCP _m＝RSCP _i+(m-i)b，

Wherein, RSCP _ifor the PCCPCH RSCP value of this base station that comprises of i metrical information after sequence, the span of i is 1 to arrive the positive integer of n.Finally, to RSCP _mfetch and return mean value,

\overset{&OverBar;}{{RSCP}_{m}} = \frac{1}{n} Σ_{i = 1}^{n} ({RSCP}_{i} + (m - i) b),

By the recurrence mean value of the PCCPCH RSCP value of this base station comprising in this metrical information of determining

as this metrical information of determining to PCCPCH RSCP value that should base station.

Fig. 3 be describe in conjunction with upper example determine the process of this metrical information to PCCPCH RSCP value that should base station, as shown in Figure 3, n metrical information sorted according to the time order and function order reporting, PCCPCH RSCP value by this base station comprising in n metrical information sorts, and the PCCPCH RSCP value of this base station after sequence is RSCP ₁, RSCP ₂... RSCP _n, the each PCCPCH RSCP value after sequence is carried out to simple regression analysis, RSCP ₁=RSCP ₂-b=......=RSCP _n+ (1-n) b, by that analogy, then fetches and returns mean value the PCCPCH RSCP value after each simple regression analysis, for example, and to RSCP ₁fetch and return mean value to be

recurrence mean value by this metrical information of determining to PCCPCH RSCP that should base station, as this metrical information of determining to should base station PCCPCH RSCP value.

In embodiments of the present invention, in order further to improve the accuracy of the movement locus of definite mobile terminal, in above-mentioned employing simple regression analysis method, determine that this metrical information is in the process of PCCPCH RSCP value that should base station, the process of determining the signal strength signal intensity regression coefficient in signal strength signal intensity regression model corresponding to this metrical information is specially, metrical information after sequence is divided into at least two groups, and every group comprises at least two metrical informations, for every group of metrical information, according to the PCCPCH RSCP value of this base station that in this group metrical information, each metrical information comprises, determine the signal strength signal intensity regression coefficient in signal strength signal intensity regression model corresponding to this group metrical information, carry out following steps for every group of metrical information: according to the signal strength signal intensity regression coefficient in signal strength signal intensity regression model corresponding to this group metrical information of determining, and signal strength signal intensity regression coefficient in signal strength signal intensity regression model corresponding to last group of metrical information of this group metrical information, judge whether this group metrical information and last group of metrical information meet merging condition, and when determining while meeting merging condition, this group metrical information and last group of metrical information are merged into one group, according to the PCCPCH RSCP value of this base station that in this group metrical information after merging, each metrical information comprises, determine the signal strength signal intensity regression coefficient in signal strength signal intensity regression model corresponding to this group metrical information after merging, otherwise, keep the signal strength signal intensity regression coefficient in signal strength signal intensity regression model corresponding to every group of metrical information constant, by the signal strength signal intensity regression coefficient in signal strength signal intensity regression model corresponding one group of metrical information at this metrical information place of determining, as the signal strength signal intensity regression coefficient in signal strength signal intensity regression model corresponding to this metrical information of determining.
