PURPOSE:To attain an efficient terminal call by collecting mobile information between zones of each terminal equipment as the funtion of time and deciding a zone selectively based on said function of time at a call time and calling the terminal equipment. CONSTITUTION:If a salesman often works at the zone A of the office or near the office in the morning and visits a zone B in charge in the afternoon, the zone existence probability of the terminal equipment differs from the morning and afternoon. For example, the existence probability in the morning is 0.7 and that in the afternoon is 0.4 in the zone A. With the zone existence probability varied with time, an exchange has a table of the existence probability at every time with respect to each terminal equipment and makes a call according to a prescribed procedure (algorithm). Then the zone A is called in the morning at first and the zone B is called in the afternoon, then the mean call zone number is below 2 to decrease the calling traffic. |
