ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to systems and methods for controlling receipt of a calling signal in a bidirectional radio paging system, and more particularly to systems and methods which provide destination non-limiting bidirectional radio paging operation.
2. Description of the Related Art
In the conventional bidirectional (calling/receiving) radio paging system, the bidirectional radio paging device (hereinafter referred to as “bidirectional radio pager”) has a database for storing limited information on paging parties and various types of response messages for responding to optional paging signals. The above response messages are to be received by paging (calling) parties, and the above paging parties' information is the information as seen by paged (receiving) parties upon issuing a locate command.
The base station equipment of the bidirectional radio paging system shares the above database with the above bidirectional radio pager. Accordingly, the above paging party's information and the selected response message are not directly transmitted and received, but only corresponding indexes are exchanged.
However, it is not only inefficient in terms of utilization of the bidirectional radio pager but also inconvenient for users that the bidirectional radio pager can respond only to limited paging parties since the base station and the bidirectional radio pager share the above database. In other words, as compared to the diversity of paging parties, the information on paging parties to which the paged party can respond is limited, so that the users must take measures for making a response separately.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a bidirectional radio paging system and method capable of paging without limiting destinations, whereby the paged party can freely select and respond to the paging party without limiting the scope of the paging parties available for response.
In one aspect of the present invention, in a bidirectional radio paging system having at least one paging device and an uplink control device in which the at least one paging device and the uplink control device share a database containing information on a plurality of paging destinations and about response messages of various contents, the at least one paging device comprises: a first data generator for transforming destination information not previously registered in the database to a data format substantially in conformity with a data format associated with the uplink control device; and a second data generator for generating radio transmission data containing a free destination flag as a message type, data related to the formatted unregistered destination information provided by the first data generator, and an index indicating an optional message content selected from the database.
These and other objects, features and advantages of the present invention will become apparent from the following detailed description of illustrative embodiments thereof, which is to be read in connection with the accompanying drawings, in which like reference symbols indicate the same or similar components.
