Abstract

PURPOSE:To improve service by deciding absence to a portable terminal out of a communication zone, executing camp-on registration and connecting the registered terminal when the portable terminal returns into the zone. CONSTITUTION:It is periodically identified by an exchange, namely, a central processing unit (CPU) 1, main storage device (MEM) 2 and communication line (TSW) 3 or the like whether portable terminals (PS) 9-1 and 9-2 come into zones A and B or not. When the PS 9-1 is in the zone A, a call is normally terminated and when it gets out of the zone A, the absence is informed of the call originating PS 9-2. Then, the camp-on registration is accepted. When the PS 9-1 returns into the zone B, the PS 9-1 and 9-2 are connected. Therefore, the original absent state is automatically identified by the movement of the PS (the movement of people) and the trouble of calling even under absence is prevented from being generated.

Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention relates to a camp-on system for a mobile phone control device (located in a conventional private branch exchange, hereinafter referred to as an exchange), and in particular, the present invention relates to a camp-on system for a mobile phone control device (located in a conventional private branch exchange, hereinafter referred to as an exchange). By registering camp-on in advance from phones that are within range, the system automatically calls back the registrant and connects to the corresponding phone when it recognizes that the specified phone has returned to the range. This is related to the method of doing so.

0002

[Background Art] A private branch exchange has a camp-on system that recognizes that the called terminal is busy, causes the calling terminal to perform a camp-on registration operation, and when the corresponding terminal becomes free, calls back the registrant and connects the user. It often has functions. This camp-on method is a method in which the call is turned on only when the call is busy, and when the caller is away, incoming calls are handled at the call forwarding destination by registering the call forwarding.

0003

[Problem to be Solved by the Invention] However, in the above-mentioned call forwarding, if the absentee fails to register the call forwarding, it will not be possible to recognize that the person is absent. There were problems that caused discomfort to people.

[0004] Also, if you forget to register a call forwarding and make a call from another terminal to a terminal that is receiving a call, it will be treated as busy, and the caller can register for camp-on. This also had the disadvantage of repeating a vicious cycle of calling, but the other party did not answer because the person was not available.

[0005] The present invention utilizes the personal nature and mobility of mobile phones in order to eliminate the problems with the camp-on function due to the inability to identify absence as described above.
In the original sense, being absent is interpreted as a time when you are out of the radio wave zone that the network can control (you cannot receive calls when you are actually out of the zone), and if you are in the area, you will normally receive calls.
To provide an excellent device that automatically notifies a calling terminal of your absence when you go out of service area, and allows you to use a camp-on function even when you are absent.

[0006]

[Means for Solving the Problems] In order to achieve the above object, in the camp-on system of an exchange that accommodates mobile terminals, the present invention treats mobile terminals outside the communication range as absent and registers them as camp-on. In this case, when the mobile terminal returns to the communication range, it connects with the terminal that has registered as camp-on.

[0007]

[Operation] The exchange determines whether the mobile terminal is within the communication range at regular intervals. When the mobile terminal is within the communication range, the call is received as usual; when the mobile terminal is out of the communication range, the calling terminal is notified of your absence and accepts camp-on registration. When the portable terminal returns to the communication range, the exchange connects the calling terminal registered as camp-on to the portable terminal. This allows you to register for camp-on when you are absent.

Embodiment FIG. 1 is a block diagram showing an embodiment of the present invention. In the figure, a control device central processing unit (CPU) 1
, main memory (MEM) 2, communication circuit (TSW) 3, extension control circuit (LC) 4 and trunk control circuit (PV)
5 constitutes an exchange, which includes multiple telephones and mobile terminals (PS).
etc. are accommodated. A wireless base station (BS) 7-1 wirelessly communicates with multiple PSs within zone A, and BS 7-2 wirelessly communicates with multiple PSs within zone B, and each PS communicates wirelessly with multiple PSs within zone B. , 7-2, wireless control circuit (FIU) 6
-1 and 6-2 are connected to the above exchange. In addition, FIU6-1, 6-2 is connected to BS7-1, 7-2 and each PS.
It controls the wireless circuit between the

Next, FIG. 2 for explaining the operation of this embodiment is as follows.
This is a flow for identifying whether PS9-1 is located in zone A. This location check is activated by the CPU 1 at regular intervals, and a command for location check is issued to the PSs to check the PSs currently existing in zone A or zone B (step a). It is checked whether there is a presence response after a certain period of time (step b). If there is a response, the PS 9-1 is considered to be located in zone A, and if not, it is assumed that the PS 9-1 has moved out of the range (for example, the movement shown in FIG. 1(a)) (step c). If PS9-1 is located in zone B due to movement as shown in Figure 1(b), PS9-1
By registering the location from 1, the out-of-service state is regarded as the in-service state. In this way, the CPU 1 always knows the PSs located in each zone. For example, in FIG. 1, if PS9-1 is located in zone A and PS9-2 is located in zone B, when PS9-2 calls PS9-1, the call arrives at PS9-1.

[0010] In FIG. 3, PS9-2 is in zone B;
PS9-1 shows the flow of out-of-range camping when the user leaves zone A by moving as shown in FIG. 1(a).

[0011] PS9-1 is in zone A as shown in FIG. 1(a).
When the PS9-1 is out of range, the CPU 1 determines that the PS9-1 has gone out of range. In this situation, from PS9-2 to PS9-1
When a call is made, a busy tone or character display is sent to PS9-2 to notify that PS9-1 is out of range, and PS9-2 is notified that PS9-1 is out of range.
S9-2 performs an out-of-range camp-on registration operation (such as dialing or pressing a one-touch function button).

[0012] The CPU 1 performs out-of-range camp-on registration and notifies the PS9-2 of the registration (tone, etc.). PS9-2 waits for on-hook operation.

On the other hand, the CPU 1 periodically identifies whether or not the PS 9-1, which is camping out of the service area, is within the service area. FIG. 4 shows the flow of this out-of-range camp-on monitoring. This location check is activated by the CPU 1 at regular intervals and determines the information in (step c) in FIG. Here, PS9-1
moves as shown in Figure 1(b) and returns to zone B, the CPU
1 receives notification of PS9-1's location (for example, location registration notification), and P who has registered PS9-1 as camp-on.
A call arrives at S9-2. At this point, the Camp On registration status will be automatically canceled.

[0014]

[Effects of the Invention] As explained above in detail, according to the present invention, the original absence state can be automatically identified by the movement of the terminal (movement of the person), so incoming calls during absence are automatically treated as busy. The calling terminal can confirm that the receiving terminal is absent, and by registering camp-on at this time,
Since the camp-on call is made when the receiving terminal is present, the conventional problem of calling even when the terminal is absent is prevented, and serviceability for the calling terminal can be expected to be improved.
