Abstract

PURPOSE:To easily ensure a broad area paging system even for any paging system by providing an adaptor on each paging system arranged to plural areas so as to interconnect the paging systems through an exchange network. CONSTITUTION:For example, a signal sent from the pager base station 31 of a paging system 1 to radio transmitters (41-1) to (41-n) is inputted also to an adaptor (A) 11. The adaptor (A) 11 implements the functions of detection of the presence of the broad area which all other pager base stations are to be called, the transmission of a message, the generation of a signal being an instruction signal for the transmission of all other pager base stations, and transmission interface to the exchange network and the management of them. A signal inputted from the adaptor (A) 11 to the exchange network 51 is sent to all adaptors (B) 21-(B)26, which implement the reception interface from the exchange network 1, the conversion of the signal into signal suitable for the entry to the pager base station and the management of them and the broad service area is formed through the transmission to the entire area via pager base stations 31-36 and each radio transmitter.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wide area paging system, and more particularly to a wide area paging system which enables a mobile unit to make radio calls over a wide area.

[0002]

2. Description of the Related Art Generally, a paging system has a service system arranged in each area, or has a wide area service system in which several areas overlap with this service system, or even some from the beginning. One of the service systems was constructed as a wide-area service system that put together the areas of.

[0003]

In order to secure a wide area service by constructing the conventional service system described above, it is necessary to have a dual service system for each area and a wide area service system. Therefore, there is a problem that the expandable area is limited even if it is operated as a wide area service system.

The object of the present invention is to solve the above-mentioned problems,
It is an object of the present invention to provide a wide area paging system in which it is not necessary to have a double service system for each area and a wide area service system, and the scalability of the service area is significantly increased.

[0005]

In the wide area paging system of the present invention, a plurality of paging systems each having a pager base station and a plurality of wireless transmitters arranged in a plurality of areas are interconnected via a switching network. The paging system is provided with additional means for forming a wide area service area including the service areas of the self paging system and all other paging systems from any paging system.

Further, the wide area paging system of the present invention is
The addition means detects a signal designating whether or not the pager base station in one area is to be transmitted to pager base stations in all other areas, transmits a transmission message, and transmits all other pager base stations. Including the generation of a signal as an instruction for transmission by the mobile phone, processing of each interface with the switching network and management of these processings, and ensuring mutual connection between the plurality of paging systems via the switching network. It has a configuration designed to do.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIG. 1 is a system configuration diagram of an embodiment of the present invention. The embodiment shown in FIG. 1 has a switching network 51 and six paging systems 1, 2, 3, through the switching network 51.
Taking the case where 4, 5, and 6 form a wide service area as an example, each paging system has the same configuration. For example, the paging system 1 includes an additional device (A) 11 that constitutes an additional means, and an additional device. In addition to (B) 21, it has a configuration including a pager base station 31 and n wireless transmitters 41-1 to 41-n.

Next, the operation of this embodiment will be described.

A paging system, for example, the pager base station 31 of the paging system 1 to the wireless transmitter 4
The signals transmitted to 1-1 to 41-n are added devices (A).
It is also input to 11.

The additional device (A) 11 detects a signal indicating whether or not to send to all other pager base stations in a wide area, transmits a message to be sent, and gives an instruction for all other pager base stations to send. Signal generation and switching network 5
It manages the transmission interface to 1 and these operations.

Here, as the signal detection of the presence or absence of the wide area, for example, POCSAG (British post off) which is one of the coding formats of the pager signal is used.
ice code standardization
It is to detect a wide area code included in an advisory group signal.

Further, as a signal which is an instruction for transmission from all other pager base stations, for example, a pseudo number capable of receiving wide area service is registered in all pager base stations, and a code collated with the pseudo number is registered. Is to generate.

The signal input from the additional device (A) 11 to the switching network 51 is transmitted to the additional devices (B) 21 to (B) 26 of all paging systems.

In the add-on devices (B) 21 to (B) 26, reception interfaces from the switching network 51, conversion into signals suitable for input to the pager base station, and management of these operations are performed.

Here, as the receiving interface of the switching network 51, for example, a packet switching network with a CCITTX25 interface is used. Conversion to a signal suitable for input to a pager base station is performed by, for example, RS232C.
It is a conversion to an interface.

Included in the transmission signals from the additional devices (B) 21 to (B) 26 to the respective pager base stations 31 to 36,
If a signal as an instruction for transmitting is matched with a signal (for example, a pseudo number) registered in advance and matched, it is transmitted as a pager signal to the entire area through each wireless transmitter.

Therefore, in FIG. 2, if any of the service areas a to f of the paging systems 1 to 6 is designated as a wide area, it is possible to secure transmission as a wide area service area W covering the entire area.

[0019]

As described above, according to the present invention, the paging systems for each area can be easily connected to each other, so that each paging system can easily form a wide area paging system and a wide area service. There is an effect that can be secured.
