Counting user is from base station B _ibe associated with B _jfrequency, be designated as f _ij, normalization f _ijobtain state transition probability a _ij:

$a_{\mathrm{ij}}=\frac{f_{\mathrm{ij}}}{\underset{j}{\mathrm{\Σ}}{f}_{\mathrm{ij}}}$

Suppose that the transfer between base station is equiprobable, set up space correlation probability matrix A, space correlation probability matrix A can be expressed as:

$A=\left(a_{\mathrm{ij}}\right)=\left[\begin{array}{ccccccc}1/7& 1/7& 1/7& 1/7& 1/7& 1/7& 1/7\\ 1/4& 1/4& 1/4& 0& 0& 0& 1/4\\ 1/4& 1/4& 1/4& 1/4& 0& 0& 0\\ 1/4& 0& 1/4& 1/4& 1/4& 0& 0\\ 1/4& 0& 0& 1/4& 1/4& 1/4& 0\\ 1/4& 0& 0& 0& 1/4& 1/4& 1/4\\ 1/4& 1/4& 0& 0& 0& 1/4& 1/4\end{array}\right]$

3. the action trail matrix that space time correlation matrix is determined based on telex network sequence of events is utilized.

User behavior track matrix P is determined according to the time of advent of user in certain base station range and the time of staying:

Wherein, p _ij=1 represents that terminal is from base station B _ibe switched to base station B _j.As shown in Figure 4, user behavior track matrix notation is:

$P_T=\left(p_{\mathrm{ij}}\right)=\left[\begin{array}{ccccccc}0& 0& 0& 1& 0& 0& 0\\ 0& 0& 0& 0& 0& 0& 0\\ 0& 0& 0& 0& 0& 0& 0\\ 0& 0& 0& 0& 1& 0& 0\\ 0& 0& 0& 0& 0& 0& 0\\ 0& 0& 0& 0& 0& 0& 0\\ 0& 0& 0& 0& 0& 0& 0\end{array}\right]$
