PURPOSE:To prevent the increase of scale in call processing program and also to facilitate the easy change in program such as addition, deletion, etc., by setting the state (e.g., busy, all) of an upper call and deciding a task according to the upper call state, an input event and a task decision table. CONSTITUTION:In case such a task that has the common state of each call to a specific input event type is designated, the state of a high-order call representing the states of calls is set instead of a case where an input event is set at the state of each call. Then a task is decided. For this purpose, a task decision table 22a is provided to a main memory 22 of a high performance terminal 2. Then a call state table 220 of the table 22a stores states 809 all, 907 busy and 908 all of an high-order call in addition to each call state. While an event type-based table 221 stores the input event types (incoming request, data information request, etc.) for execution of a common task. Furthermore a service counter table 222 stores the task names (transfer service, store service, data information service, etc.) which should be executed according to the stored input event types. |
