Abstract

PURPOSE:To set a line of interrupt emergent talking of a VIP telephone call even when a fixed radio station is busy without complicated constitution by providing a search receiver to the fixed radio station, receiving a call of other portable telephone set during talking and applying forced interrupt connection or the like based on required analysis result. CONSTITUTION:A search receiver is provided to a fixed radio station FRS connecting to a public line and a wired telephone set via a private branch exchange PBX and a radio system controller or the like. When the search receiver of the radio station FRS in busy state connecting to a portable telephone set PTEL in the area receives a call from the telephone set PTEL not busy, the analysis comparing the caller class, call request class and talking class or the like with those during communication at present is implemented and the interrupt speech or urgent speed for predetermined VIP is set without large sized configuration.

Description

[Detailed description of the invention] (Technical field to which the invention pertains) The present invention provides a call service method for realizing VIP or emergency calls in a mobile phone system. Outgoing.

NTT's car telephone is currently available as a communication system that processes incoming calls and allows conversation with a desired party.

NTT also provides mobile phone services using this network. On the other hand, as cordless telephones have become more widespread, cordless telephone systems have been expanded, and it has become possible to realize a local mobile telephone system as a cordless telephone system as shown in FIG. In this case the frequency is 2
89 using 50/380MHz including control channel
It is a small zone system with a duplex service radius of about 50 m using a small antenna power of 10 mW.

This system consists of a radio control device, a fixed radio station, and a mobile phone. Each element of this configuration will be briefly explained.

Mobile phone (P): Has the function of accessing a wireless system control device via a fixed wireless station via a wireless line and automatically registering its location. If it is necessary to register the location with another fixed wireless station as the mobile phone moves, it has the function of accessing the wireless system control device and changing the location registration. Call operations can be made from any location within the service area.

Fixed radio station (FR3): Converts downlink signals from a radio system control device into radio waves and transmits them to a mobile phone, allowing incoming calls and telephone conversations. On the other hand, by receiving and demodulating the upstream radio wave signal from the mobile phone and transmitting it via wire to a wireless system control device, it is possible to perform an outgoing operation and make a call.

Radio system control equipment (RCE): The radio system control equipment is a fixed wireless station that covers the radio wave zone where the mobile phone is located, and a private branch exchange P that has a one-to-one correspondence with the mobile phone.
This is a device that connects to an ABX extension line when making or receiving a call to form a communication path.

In this way, mobile phone systems have become readily available.

-a, the fixed wireless station has one set of transmitter and receiver, and can set up a wireless line to one mobile phone within its service area.

Therefore, once a wireless line is set up and a call begins between a fixed wireless station and a mobile phone, other mobile phones within the same service area cannot make or receive calls at all, which is a system drawback. there was. In order to avoid this, the problem can be solved by providing multiple transmitters and receivers at the fixed wireless station, but this has the drawback of being uneconomical.

Furthermore, in order to accommodate VIPs, certain fixed wireless stations were designated exclusively for VIPs and did not respond to any call requests from general mobile phones, an inefficient way of using the station. Furthermore, there was no method for interrupting incoming calls at all, and there was a problem in terms of efficiency in how fixed wireless stations were used.

(Object of the Invention) The object of the present invention is to solve these drawbacks and prevent interruption by VIP when a fixed wireless station is occupied, emergency 2. The purpose of the present invention is to provide an economical call service method that allows setting up a wireless line for calls.

(Structure and operation of the invention) In order to achieve this object, the present invention provides a call service system in which a search receiver is provided at a fixed wireless station, and even when a mobile phone is on a call, the same receiver receives calls. Detects a call from a mobile phone and detects the connection requesting number or calling party number or specific code, and also detects the connected mobile phone number or code in the case of an incoming call from a wired line. Analyzing numbers or codes to issue a warning to a busy line based on a certain judgment, forcibly disconnecting the line to urge the line to be released early, and sometimes disconnecting the line. This enables VIP and emergency response, and is controlled so that the same response can be achieved with a small number of installed fixed wireless stations.

(Example) The present invention will be explained in detail below with reference to the drawings.

The basic configuration of the hardware for explaining the present invention will be explained first.
As shown in the figure. In Figure 1, the wireless system control device is a private branch exchange PBX.
However, if the wireless system control device RCE is provided with a switching function, the present invention can be implemented in the same way even when there is no private branch exchange. Furthermore, although the fixed radio stations FR3 are independent from each other, similar and even higher speed processing is possible by connecting the fixed radio stations with each other by wire.

The zone configuration, which is the wireless service area, is as shown in Figure 2, where the wireless service area of each fixed wireless station is within one area of each other.
Although it is not 00%, it is preferable that they overlap. In addition, each mobile phone P location and each fixed wireless station F
R3 consists of two receivers, one for calls and one for search, which can receive signals independently.The receiver for search can operate completely independently from the receiver for calls. , operates independently even when the telephone receiver is in operation.

This is possible even with a single receiver if call interruptions are allowed. The control channel of the wireless line between the fixed wireless station FR8 and the mobile phone (P) is only for data transmission, but the voice channel for communication on the wireless line is between the fixed wireless station FR3 and the mobile phone (P).
In addition to voice for phone calls, for example, 1
It is assumed that data of approximately 00 bps can be transmitted.

The wired system has an accompanying data channel in addition to voice signal transmission, and data can be exchanged between the fixed radio station FR3 and the radio system controller RCE, and between other fixed radio stations, even during a call. There are various types of data channels, such as the type that accompanies digitized voice (for example, 2B+D on the 15DN digital line), and the type that interferes with the call but transmits the analog voice signal as it is, or uses outside the analog voice band. This can be realized by, and is already known.

In such a configuration, it is possible for a third party to set up a new wireless line and make a call by forcibly disconnecting the wireless line that is already in use by the following procedure.

The fixed wireless station FR3 constantly or intermittently sends the identification number (ID number) of its own station and the registered mobile phone number or the current level or higher to the mobile phone P on the broadcast channel to register the location except when making a call. A mobile phone number that can be received is sent.

Fixed wireless station FR3 also uses its own identification number (I) even during a call.
D number), the mobile phone number of the other party, and the mobile phone number registered with the user or a mobile phone number that can receive reception at a current level or higher, on a data channel outside the voice band. Regardless of whether the fixed radio station FR3 is transmitting or receiving, the T-chi receiver receives not only the control channel but also the communication channel, and receives call requests from mobile phones, mobile phone numbers that can be received above a certain level, and the mobile phone. The identification number (ID number) of the fixed wireless station FR3, which is being received or registered by the mobile phone which is transmitting outside the voice band, is received and stored in the memory.

Similarly, the mobile phone P is registered with the fixed wireless station identification number (ID number) for location registration issued by the fixed wireless station (FR3) using the search receiver regardless of whether it is making a call or not. In addition, when a fixed wireless station (for example, FR3-2) is in the middle of a call, the identification number of the fixed wireless station FR3-2 and the mobile phone number of the other party on the communication channel must be input to the same fixed wireless station. I have received a mobile phone number registered with . In addition, during a call, the mobile phone P station displays the identification number of the own station, the fixed wireless station identification number of the other party, the availability information of the same fixed wireless station, and the fixed wireless that can be received at the current level or higher received by the search receiver. The station identification number and other registered fixed wireless station identification numbers are being sent on a data channel other than the voice band.

This will be explained below with reference to FIG. In FIG. 2, FR3 indicates a fixed radio station, P indicates a mobile phone, and RCE indicates a radio system control device. For example, while mobile phone P station #1 is on a call with fixed radio stations FR3-, 2, it receives broadcast information sent from fixed radio station FR3-1 using a search receiver other than for calls, and Mobile phone P station #1 learns that it is within the service range of mobile phone P station #1.
During the call, the fixed wireless station FR3-2 is sending data outside the voice band to the fixed wireless station FR3-2.
In R3-2, mobile phone P station #1 is fixed wireless station FR3-
You can know that you are within the service area of 1.

In FIG. 2, mobile phone P station #1 is currently connected to fixed radio station FR5-2. Mobile phone P location #l and mobile phone P location #
It is assumed that station number 2 is within the same service area as fixed radio station FR3-2.

Furthermore, it is assumed that mobile phone P station #1 also belongs to the service area of fixed radio station FR5-1.

When a call is started with the fixed radio station FRS-2's mobile phone 11P location #l, the telephone number l of the mobile phone P location #l of the other party is stored as data received by the receiver for the call. In addition, fixed wireless station FR3-2 is a registered fixed wireless station of mobile phone P station #1 that is recorded by mobile phone P station #1 with a search receiver and emits outside the voice band, or is currently a fixed wireless station of mobile phone P station #1. Fixed wireless station F where 1 can be strongly received
It is possible to know the identification number A of R3-1 and the availability information of the fixed wireless station.

Next, mobile phone P station #2 requests a call within the service area of fixed radio station FR3-2. However, since fixed wireless station FR3-2, which is the parent of the same zone, is being used, call processing cannot normally be performed. In the present invention, the fixed radio station FR3-2's receiver for searching for calls other than calls knows that the mobile phone P station #2 is about to make a call. Next, the fixed wireless station FR3-2 is connected to the mobile phone P station #1 that is currently on the call.
checks whether it is possible to talk to a station other than the fixed radio station FR3-2, and learns that it is possible to talk to a fixed radio station FR3-1.

Next, the fixed wireless station #2 sends a connection change command to the fixed wireless station FR3-1 via the wired data channel or voice communication path to the wireless system control device RC, and at the same time sends the mobile phone P It sends the telephone number l of station #1 and the identification number B of its fixed wireless station FR3-2 as data. Upon receiving this, the radio system control device RCE puts the wired system of mobile phone #1, which is currently on the call, on hold. The fixed wireless station FR3-2 that sent this sends an interrupt signal and a command to connect to the fixed wireless station FR3-1 to the connected mobile phone P station #1, disconnects the current wireless line, Leave the channel free.

Fixed radio station F receives a call from the radio system controller RCE
R3-1 preferentially waits for a signal from mobile phone P station #1 which will subsequently request connection. Therefore, no other connections will be accepted for a while. Mobile phone #
Fixed wireless station FR3 was waiting for a wireless connection request from 2.
-2 immediately sets up a wireless line with mobile phone #2,
Fixed radio station FR3-2 and mobile phone P station #2 enter into an opening call. Similarly, mobile phone P station #1 is a fixed wireless station FR.
A connection request is made to FR3-1, and connection is made to fixed wireless station FR3-1. The fixed radio station FR3-1 informs the radio system control device RCE of this situation, releases the hold for the mobile phone P station #1, and starts a call.

On the other hand, mobile phone device #l was talking comfortably, but due to the influence of mobile phone device #2, the call was temporarily disconnected, but after a momentary disconnection, the connection was changed and the conversation continued. can be done.

In the above explanation in which the connection change between mobile phone P station #1 and mobile phone P station #2 becomes possible, the fixed wireless station to which the connection change is made is available, and there is no particular problem.

If it were blocked, such operations would not be possible. In such a case, (1) Forcibly disconnect the current call and create a call path for a new requester.

■Disconnect after a certain period of time with advance notice.

■By warning that there is a call request from another person, the current caller is urged to end the call and is expected to disconnect voluntarily.

Tell me what's going on in episode 0.

There are four choices:

Whether or not to disconnect during a call cannot be uniformly handled. Therefore, it is wise to perform the above processing depending on the type of telephone number, special code, etc.

An example of the processing classification will be explained below.

Here, if there is an interruption request such as an outgoing call request or an incoming call request while a certain fixed wireless station is talking to a general person's mobile phone, and other fixed wireless stations for connection change are occupied or the fixed wireless station A case will be explained in which the service area of the fixed wireless station is independent from the service area of other fixed wireless stations without overlapping with them.

First, the interrupt level is assumed to be 3 ranks. That is,
``General Jr.VIPJ and ``Urgent.'' It is clear that "general" and I/I PJ are distinguished by telephone number.

For example, numbers in the 8000 range are treated as VIP numbers, and other numbers are treated as "general" numbers.

For "emergency" calls, use a telephone number with "#" added to the beginning of the telephone number. The interrupt levels are "caller" and "caller". In addition, when the other party is unknown due to an incoming call, etc., it is treated as "general". Furthermore, there are two types of interrupts, one for "incoming call" and one for "outgoing call." At the time of "incoming call", when the radio system controller RCE receives a call, it searches its internal memory, searches for the fixed radio station where the called mobile phone is registered, and sends the data channel to the fixed radio station. Notify the incoming call through.

The mobile phone receiving the call may be currently on a call or may be on standby within the same service area. The fixed wireless station receives this and checks whether it is an emergency with a "#", an rV I PJ in the 8000 series, or a "general".

If this is an emergency 21 call with "#" attached, the user knows that the situation in which he/she is currently making a call is a general-to-general call, and the process is started. At this point, since an emergency call has interrupted the general call, a warning sound is output to the general call, and after 10 seconds, for example, the call is forcibly disconnected, a new call path is formed, and the emergency call is made. In other cases, if an emergency call interrupts the caller while the caller is already making an emergency call, for example, a warning sound B is emitted to the caller, and the caller who hears this can judge the situation and disconnect the call. It is up to the caller to decide whether to give the line to the emergency caller who has interrupted, or to ignore the warning tone B and continue the call. There are various other combinations, and examples of these combinations and their flows are shown in FIG.

Although the above description has been made regarding incoming calls, the same applies to the case where a certain mobile phone within the service area of a certain fixed wireless station is making a call while another mobile phone requests a call.

That is, the fixed radio station FR3-2 learns that the mobile phone P-2 has requested a call using a search receiver other than a call receiver.

The fixed radio station FR3-2 is already in the process of setting up a wireless line with the mobile phone P-1, but the fixed radio station FR3-2 checks whether the call is already in progress or what level it is at, as shown at 7 in Figure 3.
I understand 3-2 myself. Therefore, what level the call request from the mobile phone P-1 is at this time is known, and the level of the connection change, such as whether it is a warning sound or a forced disconnection, is decided by comparing the levels and processed. These are exactly the same as when receiving a call.

It should be noted that the process shown here is just an example, and it goes without saying that various changes can be made, as it is determined by the policy whether or not the VIP person is allowed to interrupt even during an emergency call, for example.

Although the present invention has been described with respect to a mobile phone system having the configuration shown in Fig. 1, it can be applied in exactly the same way to a simpler system with one fixed wireless station and two to three T* band charging carriers. I can do it.

(Effects of the Invention) As described above, according to the present invention, data from fixed wireless stations and search receivers of mobile phones can be effectively used to facilitate interruptions, and emergency, VIP, etc. , general and outgoing 1 incoming calls, level of active caller and interrupter level, connection change, warning sound 1 forced disconnection.

It has become possible to provide detailed services for each combination, such as non-interruption, so that a lower-ranking person who is already on a call will be unconditionally interrupted when a higher-ranking person makes a subsequent call. It is now possible to make comfortable calls.
