Abstract

PROBLEM TO BE SOLVED: To surely send out call signals for the incoming call from a specified subscriber even when a radio channel is in congestion. SOLUTION: A CPU 19 monitors the presence/absence of call termination from a TEL 2 through an INF 11, checks whether or not the radio channel is congested through a trunk TRK 13 first when the call termination is present, identifies and judges whether or not the subscriber of the call termination is the specified subscriber by retrieving a subscriber data base from a memory MEM 19 when it is congested and records priority arrangement so as to preferentially send out the call signals in the next and succeeding cycle in the MEM 18 when it is the specified subscriber. When the radio channel is not congested, an SW 12 is controlled so as to connect an SG 17 to the TRK 13 for any subscribers and radio call signals to an opposite subscriber are sent out through an antenna 14 to the radio channel.

Is in a congested state, the control unit 111
1 is connected to the automatic answering trunk 231 and the trunk 231 causes the telephone 121 to send a message prompting voice mail. When the caller selects voicemail, control unit 111 connects trunk 114 to voicemail device 112 and causes voicemail device 112 to record a message from the caller. On the other hand, when there is an outgoing call from the wireless terminal 134, the control unit 111 connects the trunk 115 to the automatic answering trunk 232, and causes the trunk 232 to send a message prompting voice mail monitoring. If the caller chooses to monitor, the control unit 111 connects the trunk 115 to the voice mail device 112 and
12 sends a message addressed to the terminal 134.

[0005]

The call processing system of the conventional radio paging system has a configuration in which when a radio line is in a congested state, a message from a caller is temporarily recorded in a voice mail device by a caller's selection. Therefore, there was a problem that the service to the caller was lacking in immediacy.

[0006]

According to the present invention, there is provided a paging processing system for a radio paging system which employs a fixed period system for transmitting a signal to a radio line. As a result of searching the subscriber database, in the case of the specific subscriber, even if the radio line is congested and the call signal transmission arrangement to the radio line cannot be arranged in the current arrangement cycle at the time of the incoming call, priority is given after the next arrangement cycle. The paging signal transmission arrangement is performed n times (an integer of n ≧ 2) which is set in advance, and the paging signal is transmitted to the wireless line at the arrangement period in which the paging signal transmission arrangement is set.

[0007] The paging processing method of the paging system of the present invention is a paging processing method of a paging system that employs a fixed-period system for transmitting a signal to a radio line. In order to improve the probability of reception, a preset number of transmissions to be performed a plurality of times are automatically reduced to one, and incoming calls from specific subscribers to be accommodated are preferentially arranged in the next allocation cycle, For the incoming call, when the radio line is congested, a predetermined number of consecutive paging signals for the specific subscriber are arranged after the next arrangement cycle that is continuous with the next arrangement cycle at the time of arrival, and the paging signal transmission arrangement is set. The call signal is transmitted to the wireless line at the arranged arrangement cycle.

According to a paging processing method of a paging system of the present invention, a paging processing method of a paging system adopting a fixed period method for signal transmission to a radio line, wherein the paging system includes a radio telephone exchange device, The wireless telephone switching device includes a subscriber circuit that interfaces with a plurality of subscriber telephones to be accommodated, a trunk circuit that interfaces with the wireless line via an antenna, and a receiver that receives a calling number from the subscriber telephone. An announcement device for announcing the status of the system to the subscriber telephone; a signal generator for generating various signals including a call signal; a ranking of whether the subscriber telephone is a specific subscriber or a general subscriber; Is a congestion state, a storage device for storing a periodic arrangement of a call signal transmission order for the specific subscriber, A central control unit for controlling the entire telephone exchange device, wherein the central control unit preferentially performs the processing of transmitting the call signal of the specific subscriber even when the radio line is congested, The number of arrangement cycles for transmitting a call signal for an incoming call to the subscriber is fixed to a preset number of times n (an integer of n ≧ 2) and stored in the storage device, and when the specific subscriber receives an incoming call, a call signal to the current arrangement cycle is received. Even if the transmission arrangement cannot be performed, it is arranged to always transmit the call signal preferentially after the next arrangement cycle.

Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing a wireless telephone exchange apparatus to which one embodiment of the present invention is applied, FIG. 2 is a flowchart showing a first operation of a calling process in the application apparatus shown in FIG. 1, and FIG. 6 is a flowchart showing a second operation of the calling process in the application device shown in FIG.

Referring to FIG. 1, a radio telephone switching apparatus 1 of the present application includes a subscriber circuit (INF) 11 for interfacing with a subscriber telephone (TEL) 2 to be accommodated, and a trunk for interfacing with a radio line via an antenna 14. A circuit (TRK) 13, a receiver (REC) 15 for receiving a calling number from the TEL 2, an announcement device (ANW) 16 for announcing the status of the system to a subscriber, and a signal for generating various signals such as a call signal. A generator (SG) 17;
A storage device (ME) that stores the ranking of a subscriber as a specific subscriber or a general subscriber, and stores a periodic arrangement of a call signal transmission order for the specific subscriber when the radio line is in a congested state.
M) 18 and a central control unit (CPU) 19 for controlling the entire wireless telephone exchange 1.

Next, a first operation of the call processing of the wireless telephone exchange 1 of the present application apparatus will be described with reference to FIGS.

The CPU 19 executes TEL2 via INF11.
It monitors whether there is an incoming call from (S21), and when there is an incoming call,
First, whether or not the wireless line is congested is checked via the TRK 13 (S22). If congested, the called subscriber is a specific subscriber by searching the subscriber database from the MEM 19 for identification. A determination is made (S23), and TEL
If the second subscriber is not a specific subscriber, the ANW 16 is activated to make a recall request (S26). If the specific subscriber is a specific subscriber, a call signal is preferentially transmitted to the MEM 18 after the next cycle. Record the preferred placement.

If the radio line is not congested in S22, the SW 12 is controlled to connect the SG 17 to the TRK 13 for any subscriber, and a radio call signal is transmitted to the other subscriber via the antenna 14 via the radio line. (S2
5).

Next, a second operation of the calling process of the wireless telephone exchange 1 of the present application device will be described with reference to FIGS.

In FIG. 3, the CPU 19 arranges the call signal preferentially after the next cycle in S24 shown in FIG.
Performs a process from the MEM 18 to determine whether or not the call signal can be arranged for the incoming call of the specific subscriber of TEL2 in the next arrangement cycle (S30). If the call can be arranged, it is stored in the MEM 18 so as to preferentially send a call signal to the specific subscriber of TEL2 in the next call cycle, and in S35, SW12 and SG17 are sent in order to send a radio call signal in the next call cycle.
And TRK17 are controlled.

If it is not possible to arrange in the next arrangement cycle at S30, the ME is set so that the call signal can be transmitted with priority (n ≧ 1 integer) consecutively after the subsequent arrangement with priority.
It is stored in the M18 (S32), and when the period in which the call signal can be preferentially arranged is reached, the wireless call signal is transmitted by the same control as above (S35).

As described above, in the present embodiment,
The CPU 19 searches the subscriber database of the MEM 18 at the time of an incoming call.
In other words, even in a state where it is difficult to arrange a call signal to a wireless line in the current arrangement cycle, it is necessary to preferentially perform a preset number of call signal arrangements of n times after the next arrangement cycle, so that a specific subscriber can be allocated. As a result, services can be provided more reliably than ordinary subscribers.

[0019]

As described above, according to the present invention, in a call processing system of a radio paging system which employs a fixed period system for signal transmission to a radio line, a calling subscriber receives a result of a search of a subscriber database upon receiving a call. In the case of a specific subscriber, even if the radio line is congested and call signal transmission allocation to the radio line cannot be performed in the current allocation cycle at the time of incoming call, n times (n ≧ n) set in advance from the next allocation cycle. The following effects can be obtained by performing the call signal transmission arrangement of (integer of 2) and transmitting the call signal to the radio line at the arrangement period in which the call signal transmission arrangement is set.

The first effect is that, even when the radio line is congested, a specific subscriber can perform call processing preferentially, so that a troublesome operation such as re-calling a subscriber at a wrong timing is not required. There is an effect that can be.

The reason is that even if the call signal cannot be arranged in the current arrangement cycle, it is preferentially arranged in the next arrangement cycle and thereafter.

The second effect is that even if the radio line is congested, the call cannot be called once due to the influence of the "second call discard function at the time of congestion".

The reason is that, for a specific subscriber, the call signal transmission arrangement count is set to n consecutive times without performing the second call abandonment.
