Call reception control method in wide area radio pager capable
First Claim
1. A call reception control method applied to a wide area radio pager, comprising the steps of:
- (a) setting a receiving channel of the radio pager by a home channel, which is a channel associated with an area originally registered as a service area for the radio pager, and then waiting for a reception of radio call signals;
(b) determining whether or not area movement identification data is received from a system associated with the radio pager, and if it is determined that area movement identification data from the system is received, then recognizing a situation, in which an area movement of the radio pager is to occur, while storing an area code carried in the received area movement identification data;
(c) determining whether or not an area movement of the radio pager occurs;
(d) if it is determined that an area movement of the radio pager occurs, then alternately changing the receiving channel of the radio pager to the home channel and a call switch channel, which is a channel associated with an area represented by the stored area code, until a call signal is received; and
(e) if a call signal is received via the call switch channel, then determining the area movement of the radio pager to be completed and setting the receiving channel of the radio pager by a channel associated with the area at which the area movement of the radio pager is completed.

Abstract
A method for controlling a call reception operation in a wide area radio pager, which is capable of providing a continued stable radio call service to the radio pager without generating errors in receiving radio call signals even when the user of the radio pager is positioned in a boundary area between adjacent areas during his area movement. Radio call signals, which are transmitted from a base station, are carried with identification data containing information associated with an area reported to the communication company end as a destination area to which the user of the associated wide area radio pager is to move. Based on such area movement ID data, the radio pager recognizes the destination area to which the user of the radio pager is to move. When an area movement of the radio pager occurs, the receiving channel of the radio pager is changed using only the channel associated with the area represented by area movement ID data received at the radio pager, without using channels associated with all available areas one by one in a predetermined order. Therefore, there is no channel reception nor area recognition error in boundary areas.

7. A call reception control method applied to a wide area radio pager, comprising the steps of:
-
(a) setting a receiving channel of the radio pager by a home channel, which is a channel associated with an area originally registered as a service area for the radio pager, and then waiting for a reception of radio call signals; (b) determining whether or not an area movement of the radio pager occurs, and if it is determined that an area movement of the radio pager occurs, then reading out channel and area information previously stored and associated with all available areas and determining whether or not there is a channel receiving a call signal, while setting a receiving channel of the radio pager by channels based on the read-out channel information one by one in accordance with a predetermined order; (c) if it is determined on the basis of the determination at step (b) that there are at least two channels receiving call signals, then determining an area, at which the radio pager is currently positioned, as a boundary area, and outputting a signal for recommending an area recognition mode of the radio pager to be set in a manual mode; (d) if a user of the radio pager switches the area recognition mode of the radio pager to a manual mode and then sets the current area of the radio pager, then setting the receiving channel of the radio pager by a channel associated with the manually set area; and (e) if it is determined on the basis of the determination at step (b) that there is only one channel receiving a call signal, then determining the signal-received channel as the receiving channel of the radio pager, detecting area information carried via the determined channel, thereby recognizing an area corresponding to the determined channel, and setting the receiving channel of the radio pager by a channel associated with the recognized area. - View Dependent Claims (8, 9)
