In the figure, 1A is a private branch exchange (PBX), which is installed in a company or a business office and connects a large number of telephones, facsimile machines, and other terminals to one office line, and establishes connections between these terminals. Do. The private branch exchange 1A is provided with a location registration storage unit 1B for performing location registration of the portable terminal 4A with respect to the base stations 8a and 8b. Since the portable terminal 4A may move beyond the service area of the base station in the permanent location, it is necessary to constantly update the location registration to manage the location of the portable device. The location registration storage unit 1B is used for this management.

An identification information storage device 11 includes a CPU, a RAM, a ROM, and the like (not shown).
A program for controlling the CPU is written in M, and a message (identification information) corresponding to each of the base stations (in this embodiment, base stations 8a and 8b described below) is stored in RAM. I have. When the terminal used is a portable device, the RAM also stores a message (identification information) corresponding to a specific number assigned to the portable device. The contents of these messages can be arbitrarily changed by writing them to the RAM.

Here, the message corresponding to the base station is:
For example, if the base station 8a sets a conference room on the third floor of the office as a service area, the base station 8a is set to "3F KEY STITCH". The message corresponding to the specific number is, for example, location information corresponding to the base station. The location information also includes addresses of prefectures, municipalities, and so on. The identification information storage device 11 has a built-in backup battery so that the contents of the RAM are not erased due to a power failure or the like.

The identification information storage device 11 is a private branch exchange 1A.
When there is an inquiry for a message corresponding to a base station or a message corresponding to a specific number, the contents of the RAM are searched, and if there is any inquiry, this is output. In addition,
A cassette tape is used for storing the message in addition to the RAM. When a cassette tape is used, a backup power supply is not required.

Each of the base stations 8a and 8b is connected to the private branch exchange 1A. Each of the base stations 8a and 8b is provided with a wireless device so that it can wirelessly access the portable terminal 4A. The base station 8
Each of the service areas 3a and 8b is installed at a distance such that the service areas 3a and 3b that can access the portable terminal 4A do not overlap with the other party. In this case, it is not always necessary that the service areas 3a and 3b do not overlap each other.

The portable terminal 4A includes a wireless device, a control circuit, a speaker, a microphone , a dial switch, and a
A display (for example, LCD) 5A is provided in addition to the display control circuit (both not shown) and the like. Display control circuitry is for controlling the display 5A. The base station 8 is displayed on the display 5A.
a (or base station 8 b) another extension number of the other terminal via the sent from PBX 1 A, sent from PBX 1 A via the respective base stations 8a (or base station 8b) A message (for example, “3F key” from the base station 8a as described above) is displayed. in this case,
Display control circuitry displays a message sent from the PBX 1 A at as indicator 5A.

Reference numeral 6A denotes a fixedly used terminal (general telephone), which is directly connected to the exchange 1A. A display 7A is attached to the terminal 6A, and the display 7A uses, for example, an LCD like the portable terminal 4A. The display unit 7A displays the extension number and / or message of the terminal sent from the private branch exchange 1A.

In this case, if the other terminal is a fixed terminal 6A, only the extension number is displayed. If the terminal is a portable terminal 4A, a message corresponding to the base station used by the terminal 4A is displayed. Is displayed. For example, as described above, if the base station used by the terminal 4A is the base station 8A, "3F KEY STITCH" is displayed.

Next, the operation will be described. FIG. 2 is a flowchart showing an example of a call operation of the communication system having the above configuration. For example, when the fixed terminal 6A issues a call request to the portable terminal 4A, first, at step S
At T1, the private branch exchange 1A receives this call request, and then calls the last registered base station. In this case, the base station registered in the last base station 8a.

After calling the base station 8a, the private branch exchange 1 determines whether or not there is a response from the terminal 4A in step ST2. If it is determined that there is a response from the terminal 4A in this determination, a calling process is started in step ST3. That is, while ringing the bell to the terminal 4A, the extension number “2001” of the terminal 6A is supplied and displayed on the display 5A.

Next, in step ST4, it is determined whether or not the portable device is a portable device. In this case, since the terminal 4A is a portable device, the process proceeds to step ST5.

At step ST5, the private branch exchange 1A
Queries the identification information storage device 11 for a message corresponding to the base station 8a used by the terminal 4A. Then, when a corresponding message is supplied from the identification information storage device 11, the process proceeds to step ST6, where the message is supplied to the terminal 6A and displayed on the display 7A. In this case, since the service area of the base station 8a is a conference room on the third floor, "3F KEY STITCH" is displayed on the display 7A of the terminal 6A.

On the other hand, if it is determined in step ST4 that the terminal is not a portable device, the process proceeds to step ST7, where the extension number of the receiving terminal (not shown) is supplied to the terminal 6A, and the extension number is displayed on the display 7A. Is displayed.

In step ST2, it is determined whether or not there is a response from the portable terminal 4A, and this step ST2 is repeated until a response is received. An incoming call is made for a certain period of time using the base station 8a, and if there is no response during this time, an incoming call is made to an adjacent base station. That is, the base station is sequentially changed at regular time intervals until a response is received, and a call is received.

When the portable terminal 4A responds, the base station that has received the response performs a calling process and disconnects base stations other than the base station. When there is a response from a plurality of base stations, the electric field strength is within a predetermined range, and is selected as the earliest time at which the response is received,
Otherwise cut off. If there is no response from any of the base stations within a predetermined time, the private branch exchange 1A returns busy to the calling side and disconnects the corresponding base station.

FIG. 3 is a flowchart showing an example of the operation of the communication system having the above configuration during a call. This process is executed at predetermined intervals as an interrupt process. First, in step ST10, it is determined whether or not a call is being made with the portable device. If it is determined in this determination that the mobile device is talking, the display of the called mobile device is displayed.
Since the telephone number of the calling side is displayed, step ST
Proceeding to step 11, if it is determined that the mobile device is not talking, the process returns to main processing (processing for managing the overall operation of the communication system). In this case, it is assumed that the terminal 4A is busy.

At step ST11, the private branch exchange 1
A determines whether or not an operation to input a special number has been performed on the portable terminal 4A. In this determination, if it is determined that a special number has not been input, this step ST11 is repeated until it is input, and if it is determined that it has been input, the process proceeds to step ST12.

At step ST12, the private branch exchange 1
A queries the identification information storage device 11 for a message corresponding to the base station that has received the specific number. In this case, the base station 8a is used. In the identification information storage device 11, the base station 8a
, A message corresponding to the specific number is retrieved, and if there is a corresponding message, the message is read and supplied to the private branch exchange 1A.

Upon receiving the message from the identification information storage device 11, the private branch exchange 1A supplies this message to the portable terminal 4A via the base station 8a in step ST13. As a result, a specific number is displayed on the display 5A of the terminal 4A.
The message corresponding to the issue is displayed. In this way, it is possible for both the calling side and the called side to know the information of the base station.

In the above embodiment, the identification information storage device 11 is provided separately from the private branch exchange 1A. However, the private information exchange 1A has the built-in identification information storage device 11 or has a function equivalent to the private information exchange. 1A may be provided.

In the above embodiment, the identification information storage device 11 is dedicated to the private branch exchange 1A, but a commonly used computer (including a personal computer) can be used.

In the above embodiment, each base station 8a, 8
Although a specific message is allocated to b, a single message may be allocated to a plurality of base stations as one unit.
