Embodiment Construction

[0045] Figure 4A and 4B It is a diagram illustrating the data format of radio call signals according to different signal transmission protocols, respectively. Figure 4A Given the radio call signal data format according to the POCSAG protocol and Figure 4B Gives the radio call signal data format according to the FLEX protocol.

[0046]In order to implement the present invention, it is required that the radio call signal contains area mobile identification (ID) data. Such area ID data transmitted from the system terminal should include an area ID code associated with an area that the wide area radio pager user notifies the system terminal as the area to which the user is moving. However, the radio call signal used in the existing POCSAG signal system does not contain the above data. Therefore, where the present invention is used in a POCSAG signaling system, this data is carried in the message field of the POCSAG signaling codeword. Since this data is in the form of a me...

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.

Description

technical field [0001] The present invention relates to a method of controlling call reception operations in a wide area radio pager, and more particularly to a call reception control method capable of preventing reception errors in peripheral areas. Background technique [0002] Generally speaking, a wide area radio pager is a radio pager configured to continue to provide the same calling service in a registered area in an unregistered area even when a user moves from the area in which the pager was originally registered to an unregistered area. [0003] combine now Figures 1 to 3 The construction of such a wide area radio pager, the call reception control method for the wide area radio pager, and the radio call reception error of the wide area radio pager occurring in peripheral areas are explained. [0004] figure 1 is a block diagram illustrating the construction of a wide area radio pager. [0005] Such as figure 1 As shown, the wide area radio pager includes: a r...
