Further, the incoming call order determining section 116g sets the incoming call order of the incoming call destination candidates stored in the incoming call destination storage memory 116d based on the order determination request signal from the incoming call destination determining section 116b.

Here, the operation of the central control unit 116 will be described with reference to the terminal positional relationship of FIG. 7 as an example. In FIG. 7, the wireless base stations 12 forming the wireless zone are not distributed and arranged in the physical area, but are dispersed and arranged in each specified area. Here, for example, the 1000th wireless terminal 14 calls the 4000th group.

That is, the connection control unit 116a
When receiving the response from the wireless terminal 14 of No. 0, it transmits a transmission signal to the destination determination unit 116b. Incoming call destination determination unit 11
6b, upon receiving the transmission signal, searches the subscriber database 116c using the transmission number included in the transmission signal as a key, and acquires the user type and the terminal type. in this case,
Since the number is 1000, the user type is for general use and the terminal type is PHS.

Next, the destination determining section 116b searches the subscriber database 116c using the incoming call number 4000 included in the outgoing signal as a key, and acquires a guide type for the user type and a group for the terminal type ( (See FIG. 3).

Upon receiving the user type and the terminal type of the calling side and the receiving side, the destination determining section 116b selects the user type of the calling side and the destination number of the receiving side by selecting the destination type if the receiving side is a group number. To the unit 116e.

The destination candidate selection section 116e uses the group number 4000 as a key to store the terminal group database 1
16f, and obtains all the member telephone numbers included in the group (see FIG. 4). Then, the destination candidate selection unit 116e compares the obtained member telephone number with the calling user type, and stores all member telephone numbers corresponding to the calling user type in the destination storage memory 11.
6d. In this case, since the calling user type is general, the member telephone numbers 2000 and 2001 are set.
Nos. 2002, 2003, and 3000 are stored in the destination memory 116d.

When all the member telephone numbers are set in the destination storage memory 116d, the destination candidate selection unit 116e sends a destination candidate setting completion signal to the destination determination unit 116e.
b. Here, upon receiving the destination candidate setting completion signal, the destination determination unit 116b sends the distance calculation request signal together with the transmission number to the relative distance calculation unit 116h to calculate the distance between the calling terminal and the destination candidate terminal. Send out.

The relative distance calculation unit 116h uses the originating number 1000 as a key for the location registration database 11
6i, and obtains a location registration zone where the calling terminal is located. Thereafter, the telephone number of the destination candidate stored in the destination storage memory 116d is obtained, and the location registration database 116i is searched to find the location registration zone where the terminal of the destination candidate is located (see FIG. 5). This location registration zone corresponds to wireless zones 1 to 3 shown in FIG.

Next, the relative distance calculation unit 116h searches the distance information database 116j using the location registration zones on the calling side and the destination candidate side as keys (see FIG. 6). At this time, the distance between the calling terminal and each of the destination candidate terminals is determined based on the location registration zone of the calling terminal. Note that this distance is 1 between adjacent wireless base stations 12.
Think as a unit. Then, the relative distance calculation unit 116
h stores the distance between the calling terminal and each of the destination candidate terminals in the destination storage memory 116d in association with each of the destination candidate terminals.

After the distance calculation for all the destination candidates in the destination storage memory 116d is completed, the relative distance calculation unit 11
6h sends a distance calculation end signal to the destination determination unit 116b. When receiving the distance calculation end signal, the destination determination unit 116b sends a rank determination request signal to the destination rank determination unit 116g to determine the rank of the destination selection of the destination candidates.

Upon receiving the rank determination request signal, the incoming rank determining unit 116g obtains the distance between the destination terminals and the calling terminals stored in the destination storage memory 116d, and obtains the distance between the zones. Is used to determine the ranking. At this time, sorting is performed in the short distance order. Then, the determined order is set for each terminal of a destination candidate on the destination storage memory 116d. That is, a table as shown in FIG. 8 is configured in the destination storage memory 116d.

In the case where the distances are the same among a plurality of destination terminals, the terminals are ranked the same. When the distance between zones is invalid, the order is set to the lowest. After the rank determination is completed, the incoming rank determination unit 116g sends an incoming rank determination completion signal to the destination determination unit 116b. Upon receiving the incoming rank determination completion signal, the destination determination unit 116b sends a connection instruction to the destination candidate in the destination storage memory 116d to the connection control unit 116a.

The connection control unit 116a performs connection control sequentially from the top based on the order of destination candidates in the destination storage memory 116d. When there are a plurality of destination candidate terminals having the same rank, the connection control unit 116a calls the plurality of destination candidate terminals all at once, or calls them with a predetermined priority. .

FIG. 9 is a flowchart for explaining the operation of the connection control section 116a. First, when the process is started by receiving an outgoing call (step S11),
In step S12, the connection control unit 116a accesses the destination determination unit 116b to execute the destination determination processing. Then, based on the connection instruction signal from the destination determination unit 116b, the connection control unit 116a determines in step S13 whether the destination is a local line.

Here, if it is determined that the destination is a line (YES), the connection control unit 116a proceeds to step S1.
At 4, S15, a connection process to the partner station line is executed, and the process is terminated (step S16). If it is determined that the destination is not the office line (NO), the connection control unit 116a determines in step S17 whether the destination is an extension that is, for example, a wired or wireless terminal.

If it is determined that the destination is an extension that does not belong to the group (YES), the connection control unit 116
In a, steps S18 and S15 execute a process of connecting to the other party's extension, and the process ends (step S16). If it is determined that the destination is not a normal extension (NO), the connection control unit 116a determines in step S19 whether the destination is a group extension.

If it is determined that the destination is not a group extension (NO), the connection control unit 116a executes a disconnection process in step S20 and ends (step S20).
16). If it is determined that the destination is a group extension (YES), the connection control unit 116a proceeds to step S
At 21 and S22, the order of the destination is read from the destination storage memory 116d from 1 and at step S23, it is determined whether or not there is a destination in the read order.
16d.

Here, if it is determined that there is a destination (YES), the connection control unit 116a proceeds to step S24.
Then, a built-in timer (not shown) for measuring a predetermined period is driven. Then, the connection control unit 116a determines in step S2
In 5, during the period of waiting for the elapse of the predetermined period by the built-in timer,
The called terminal is being called.

Thereafter, when a predetermined period elapses, the connection control unit 116a determines in step S26 whether or not the destination terminal has not responded. If there is a response (NO), the connection control unit 116a determines in step S15
The connection process is executed, and the process ends (step S16). If no response is received (YES), the connection control unit 116a
Executes the reading of the destination of the next candidate from the destination storage memory 116d in step S27, and again executes step S23.
Is returned to the process.

In step S23, if there is no destination (NO), the connection control unit 116a executes step S23.
At 28, it is determined whether there is a next ranking. When it is determined that there is a next ranking (YES), the connection control unit 11
In step 6a, the next order is set in step S29, and the process returns to step S22.

If it is determined in step S28 that there is no next rank (NO), the connection control unit 116a
Sets the calling terminal to the talkie device 115 in step S30.
And sends a non-response guidance to the calling terminal.

Steps S24 to S26 on the flow
The connection control unit 116a makes a call for a predetermined time when there is a destination, and reads out the next destination in the case of no response.

In this regard, as a second embodiment,
If there is a dial input or a one-touch key press indicating a non-answering call at the terminal in advance, there may be a case where a call is not received. In this case, the destination candidate selection unit 116e
The dialing number indicating the non-answering of the incoming call detected by the connection control unit 116a or the number of the called party whose one-touch key is pressed is stored in a database (not shown).

When making a connection to the grouped destination terminals, the destination candidate selection unit 116e sequentially determines whether or not there is a terminal in the database for which no response is set, and The destination candidates other than the terminal for which no response is set are stored in the destination storage memory 116d.

That is, the connection control unit 116a can remove the terminal for which no response has been set from the destination candidates and place a call in accordance with the order set in the destination storage memory 116d. It is possible to reduce the time required to make an incoming call to a candidate.

Next, FIG. 10 is a flow chart showing the operation of the destination determination section 116b in step S12 shown in FIG. First, when the process is started by receiving a call destination determination request signal from the connection control unit 116a (step S31), the call destination determination unit 116b determines in step S32 the subscriber from the transmission number included in the call destination determination request signal. The user type stored in the database 116c is acquired, and in step S33, it is determined whether or not there is a called number in the subscriber database 116c.

If it is determined that there is no incoming number (NO), the destination determining unit 116b proceeds to step S34.
Then, a disconnection instruction is sent to the connection control unit 116a, and the process ends (step S35).

If it is determined that there is a called number (YES), the called party determining unit 116b proceeds to step S36.
Then, the terminal type of the destination stored in the subscriber database 116c is searched from the destination number, and it is determined in step S37 whether the destination is an office line. If it is determined that the destination is a line (YES), the destination determining unit 116b sends a line connection instruction to the connection control unit 116a in step S38.

If it is determined in step S37 that the destination is not a local line (NO), the destination determining unit 1
In step S39, it is determined whether the destination is an extension of a wired terminal, a wireless terminal, or the like. If the destination cannot be determined, or if it is determined that the extension of the destination is not registered in the subscriber database 116c (NO), the destination determining unit 116b proceeds to step S34.
Sends a disconnection instruction to the connection control unit 116a.

If the destination can be determined or if it is determined that there is an extension of the destination (YES), the destination determining unit 116b determines the terminal type of the destination from the subscriber database 116c in step S40. Obtain and step S
At 41, the existence of the called number is confirmed.

Thereafter, in step S42, the destination determining section 116b searches for a group number. If it is determined that the incoming number is not a group number (NO), the destination determining unit 116b proceeds to step S
At 43, an extension connection instruction is sent to the connection control unit 116a.

If it is determined in step S42 that the destination number is a group number (YES), the destination determining unit 116b, in step S44, sends the destination number and the user of the caller to the destination candidate selecting unit 116e. And sends a request to the destination storage memory 116d to set destination candidates. Thereafter, in step S45, the destination determination unit 116b determines whether there is a destination candidate based on the destination candidate setting completion signal from the destination candidate selection unit 116e. When it is determined that there is no destination candidate (NO), the destination determining unit 116b proceeds to step S34.
Sends a disconnection instruction to the connection control unit 116a.

If it is determined in step S45 that there is a destination candidate (YES), the destination determination unit 1
16b sends a distance calculation request signal to the relative distance calculating unit 116h together with the calling number in order to calculate the distance between the calling terminal and the destination candidate in step S46.

After receiving the end of the distance calculation from the relative distance calculation unit 116h, the destination determination unit 116b determines the order of the destination selection of the destination candidate in step S47 by the reception order determination unit 116g in step S47. Send a request signal. After receiving the ranking determination completion signal, the destination determination unit 1
16b sends a connection instruction signal to the destination candidate in the destination storage memory 116d to the connection control unit 116a in step S48, and ends (step S35).

Next, FIG. 11 is a flowchart showing the operation of step S in FIG.
46 shows a detailed operation of the relative distance calculation unit 116h in 46. First, when the process is started by receiving the distance calculation request signal and the transmission number from the destination determination section 116b (step S49), the relative distance calculation section 116h uses the transmission number as a key in the position registration database 116i in step S50. Search to find the location registration zone where the calling terminal is located.

Next, in step S51, the relative distance calculation unit 116h reads the telephone number of the destination candidate from the top of the destination storage memory 116d. When reading out the telephone number of the destination candidate, if it is not empty at step S52 (YES), the relative distance calculating unit 11
6h, in step S53, the destination storage memory 116d
Location registration database 1 based on the above phone numbers of destination candidates
16i is searched to find a location registration zone in which the destination candidate terminal is located.

Then, in step S54, the relative distance calculating section 116h searches the distance information database 116j for the inter-zone distance by using the location registration zone information of each of the calling terminal and the destination candidate as a key, and obtains the inter-zone distance.
At 5, the inter-zone distance is stored in the destination memory 116d.

Then, in step S56, the relative distance calculation unit 116h reads the telephone number of the next destination candidate in the destination storage memory 116d, and thereafter executes step S56.
52, S53, S54, S55, S56 and all the destination candidates stored in the destination storage memory 116d are repeatedly processed.

If there is a vacancy in step S52 (NO), the relative distance calculation unit 116h sends a distance calculation end signal to the destination determination unit 116b in step S57, and ends (step S58).

As described above, central control unit 116 analyzes the outgoing call from the terminal, identifies the position of the calling terminal, and uses the result of the terminal position identification of the called side to select a destination destination in the called group. Are determined based on the relative distance between the zones to which the calling terminal and the destination candidate terminal belong, and the incoming call is sequentially received from the top according to the selection order. Therefore, when a call arrives at a group,
It is possible to provide a group incoming call service in which terminals are sequentially selected from terminals located in the zone closest to the calling terminal among the terminals in the group. Further, it is possible to provide a group receiving service according to the type of the calling terminal.
