Abstract

PROBLEM TO BE SOLVED: To provide the signal transmission area deduction system of a paging incoming call capable of minimizing a calling area for transmitting paging incoming call signals for the paging incoming call in a radio telephony system. SOLUTION: At the time of the paging incoming call, the resource information of paging group terminals 6 and 7 is read in the terminal group control part 11 of an exchange and they are eliminated from paging group terminal information when they are during communication. Thus, the number of terminals for deducing the calling area for transmitting signals from position registration information by a protocol control part 13 is reduced and the incoming call signals of the paging incoming call are transmitted only to the minimum calling area.

2. Description of the Related Art Conventionally, in a page call system of this type of portable radio telephone system, when a paging call is received, a terminal belonging to a paging group is read out by a terminal group management section of an exchange, and a paging group call is received. The protocol control unit reads out the location registration information of the terminal by handing over to the protocol control unit that sends out the signal, and determines the calling area.

FIG. 3 is a diagram showing an example of an operation sequence of a conventional page paging system, and shows a paging incoming sequence from a radio terminal A (5) to paging group terminals B (6) and C (7). .

Referring to FIG. 3, a call control unit 10 in the exchange 1 performs translation / routing control, switch control, service activation, and the like in outgoing / incoming calls. The terminal group control unit 11 manages subscriber information of a terminal to which the paging group belongs and data such as an incoming state of the paging group, and implements a paging incoming call service. The resource management unit 12 has a function block for managing the vacancy / occupancy of the terminal, and the protocol control unit 13 has a function of generating / analyzing a message to be transmitted / received to / from the wireless terminal and determining a call area for transmitting a signal from the location registration information. .

[0005] In the following description, it is assumed that radio terminal A (5) is the caller, radio terminal B (6) is idle, and radio terminal C (7) is communicating.

When the wireless terminal A (5) dials the paging group number, the exchange 1

Further, the location registration information of the terminal C (7) is read, and a paging call signal is also sent to the call area 2 (9) (25 in FIG. 3).

[0011]

However, in the above-described conventional system, when a paging call is received, a paging group terminal sends a paging signal to all paging areas registered for location. There is a problem that a load is generated on the traffic and the exchange.

[0012] The reason is that if the caller requests a paging call while the radiotelephone is not communicating, the paging call is unconditionally sent to the location registration area of all paging group terminals. This is because the incoming call signal is transmitted.

Accordingly, the present invention has been made in view of the above problems, and an object of the present invention is to minimize the transmission of a paging group incoming call signal in a paging incoming call of a portable radio telephone system. It is an object of the present invention to provide a paging incoming call signal transmission area indexing method for reducing the traffic of a radio signal channel and the load on an exchange limited to a paging area.

In order to achieve the above-mentioned object, a signal transmission area determining method for pacing incoming calls according to the present invention is provided. Protocol control for reading resource information of a paging group terminal managed by the resource management unit by the terminal group management unit at the time of a paging call, identifying a communicating terminal, and reading location registration information when paging is received. The unit is characterized in that only a paging group terminal in an empty state is delivered, thereby limiting an incoming signal transmission area of a paging incoming call to a terminal position registration area in an empty state.

[0015]

Embodiments of the present invention will be described below. In a preferred embodiment of the present invention, the switching unit includes a resource management unit having resource information such as idle / occupied status of a terminal. In the terminal group control unit that performs service control, the resource information of the paging group terminal is checked, and if the paging group terminal is communicating, the paging group terminal is deleted from the paging group terminal information from which the paging area is determined, and the received paging group terminal is received. It has a protocol control unit that reads out location registration information from the information and determines a calling area for sending an incoming call signal of a paging incoming call.

That is, in the embodiment of the present invention, when an incoming paging call arrives, the terminal group control unit that controls the service of the paging incoming call reads out the resource information of the paging group terminal from the resource management unit and is idle / blocked. Check. If the paging group terminal is communicating, the paging group terminal information is deleted from the paging group terminal information that is the source of paging area determination, and is transmitted to the protocol control unit.

The protocol control unit reads out the location registration information from the received paging group terminal information, determines a paging area for transmitting a paging incoming call signal, and transmits a paging incoming call signal.

The terminal group control unit detects a telephone in communication and deletes the telephone from the paging group terminal information, thereby reducing the paging area for transmitting a paging incoming call signal, and reducing traffic on the radio signal channel. The load on the exchange can be reduced.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of the present invention; FIG. 1 is a sequence diagram for explaining the operation of one embodiment of the present invention, and FIG. 2 is a diagram showing a system configuration of one embodiment of the present invention.

The exchange 1 connects the radio base stations 2, 3, and 4 and accommodates radio terminals A (5), B (6), and C (7). Of these, the wireless terminals B (6) and C (7) are registered as paging group extensions,
(6) is registered in the calling area 1 (8),
The wireless terminal C (7) has registered the location in the call area 2 (9). Normally, when the paging group number is dialed from the wireless terminal A (5), the call areas 1 (8), 2
An incoming call signal of a paging incoming call is sent to both of (9),
It is notified by a ring tone or the like.

The call control unit 10 in the exchange performs translation / routing control, switch control, service activation, and the like in outgoing / incoming calls.

The terminal group control section 11 manages the subscriber information of the terminal to which the paging group belongs and data such as the incoming state of the paging group and implements the paging call service.

The resource management unit 12 manages whether a terminal is idle or closed.

The protocol control unit 13 generates / analyzes a message to be transmitted / received to / from the wireless terminal and determines a calling area for transmitting a signal from the location registration information.

Next, the operation of the embodiment of the present invention will be described. In the following description, it is assumed that the wireless terminal A (5) is the caller, the wireless terminal B (6) is idle, and the wireless terminal C (7) is communicating.

When the terminal A (5) dials the paging group number, a call setup message (SETUP) is transmitted to the exchange 1 via the radio base station 2 (1 in FIG. 1).
4), sent to the call control unit 10. The call control unit 10 creates an incoming call signal for paging incoming call, and
1 (15 in FIG. 1).

The terminal group control unit 11 reads out the incoming state of the paging group and the subscriber information of the terminals B (6) and C (7) belonging to the paging group from the paging group number. Next, the resource information of the paging group terminal is read from the resource control unit 12 (16 in FIG. 1). If the terminal is busy, it is deleted from the paging group terminal information and the paging group terminal information of only the idle telephone is created. (17 in FIG. 1).

Here, since the terminal B (6) is idle and the terminal C (7) is talking, the paging group terminal information is created only with the information of the terminal B (6).

When a paging call signal (IAM) to which the created paging group terminal information is added is transmitted to the protocol control unit 13 (18 in FIG. 1), the protocol control unit 13 converts the paging group terminal information to the terminal B (6).
, And sends out a paging incoming call signal (SETUP) to the call area 1 (8) (19 in FIG. 1).

[0030]

As described above, according to the present invention,
In the paging call, an incoming signal of the paging call is transmitted only to the minimum required calling area, and therefore, there is an effect that the traffic of the radio signal channel and the load on the exchange can be suppressed.

The reason for this is that, in the present invention, when the paging group terminal is communicating, the terminal group control unit of the exchange deletes it from the paging group terminal information from which the calling area for signal transmission is determined. This is because the protocol control unit is configured not to send an incoming call signal to the calling area where the location of the paging group terminal is registered.
