Description

Private exchange system and private exchange with bluetooth function

Technical field:

The invention relates to an exchange, in particular to a private exchange system and a private exchange with bluetooth function, which can determine the position of an extension user.

Background technique:

Generally, the private switchboard in the office only has the function of forwarding incoming calls. Once a call comes in from outside, the switchboard can directly transfer the incoming call to the extension. If no one answers the extension, either other extension users will transfer the call, or the bell will ring until the set time is up before transferring to the voice system. If the frequency of incoming calls is high, other extension users will be disturbed in an environment that requires a quiet office. Moreover, if an emergency or important incoming call is wrongly connected, it will cause losses or adverse consequences, which needs to be improved.

Taiwan Patent Publication No. 453097 "Telephone Automatic Person Finding System", the extension user can use a card reader of a specific telephone extension to register with the telephone exchange with an identity card that the extension number assigned belongs to a specific telephone extension , so that the extension user's incoming calls can be forwarded to the specific phone extension. However, although the patent name is "Automatic Telephone Finding System", in fact the extension user must "record" with the telephone exchange whenever he arrives at a specific telephone extension, so it cannot be called complete automation. And, this patent can only carry out call forwarding on the extension. Once the extension user wants to go to a place without extensions, this system is obviously useless.

As shown in Fig. 2, in the figure, the private exchange 1 contains a switching device (SwitchFabric), which is connected with the outside line and connected with several extensions 2 to transfer the internal and external calls. Wherein, the switching device 11 is connected with a central processing unit 12 , and the central processing unit 12 is connected with a memory 13 and an RS232 interface 14 . The switching device 11 is connected with the external data setting device 3 and the Bluetooth detector 4 via the RS232 interface 14 and the RS232 transmission line 7 . Generally speaking, the bluetooth detector 4 and the portable bluetooth device 5 respectively have bluetooth modules 41,51 (respectively including: radio frequency unit 411,511 and base frequency unit 412,512), central processing unit 42,52 and memory 43,53 , Antenna 44,54. The bluetooth detector 4 has an additional RS232 interface 45 for connecting with the RS232 interface 14 of the switch 1 .

The function of each device can be known from the following description. There is a database in the memory 13 of private exchange 1, and database is used for storing the bluetooth address code (Bluetooth Device Address, BD ADDR, each bluetooth device all has unique code) of each bluetooth detector 4 and its corresponding extension 2, The current contact status and the processing method when leaving are shown in the example in Table 1. The bluetooth detector numbered 1 in Table 1 has three portable bluetooth devices connected to it, and their bluetooth address codes are respectively:

10.0F.03.B7.D0.01

10.0F.03.B7.D0.02

10.0F.03.B7.D0.03

The corresponding extensions are 101, 102, and 103 respectively; the current contact statuses are "Contacting", "Contacting" and "Leaving" respectively, and the processing methods when leaving are "Transfer to voicemail" and "Transfer to extension 109". ” and “Forward Voicemail”. For example, the portable Bluetooth device 5 with the Bluetooth address code 10.0F.03.B7.D0.01 connected with the Bluetooth detector numbered 1 is owned by the user of extension 101. When the user leaves the location, his The requirement is to divert incoming calls to voicemail. For the portable bluetooth devices 5 of different bluetooth address codes that other numbered bluetooth detectors contact, the situation of its incoming calls is different, but the way is the same.

Next, the data setting device 3 is used for inputting the Bluetooth address code and the corresponding extension 5 of the portable Bluetooth device 5 associated with each Bluetooth detector in the database.

In step 304, if the option to delete is selected, proceed to step 309 to select an address code record of a portable bluetooth device; then proceed to step 310: delete the address code record in the database; then return to step 303: List the paintings of the database contents, and then proceed with the following steps.

Because each detector 4 is deployed in an appropriate position according to the radio signal coverage (because the situation of each office layout is different), when a detector searches for the corresponding portable Bluetooth device (as shown in Table 1, Bluetooth Portable Bluetooth devices with address codes 10.0F.03.B7.D0.01, 10.0F.03.B7.D0.02 and 10.0F.03.B7.D0.03 belong to Bluetooth detector number 1, Others are not), then record its current contact status in the database as "in contact", if a detector can not find the portable bluetooth device to which it belongs, then record its current contact status in the database as "leaving".

As shown in Figure 4, it is the bluetooth detector operation flow chart of the private exchange with bluetooth function of the present invention; At first, carry out step 401: turn on the bluetooth detector; Then carry out step 402: activate inquiry timer; Then, enter step 403: Waiting state. The process is carried out in three situations: first situation: proceed to step 404: when the detector receives a reply message from the bluetooth device, proceed to step 405: check whether the database belongs to the portable bluetooth device; if not , then enter step 406: waiting state; if it belongs to the portable Bluetooth device, then proceed to step 407: set the reply flag (flag) to 1; after that, enter step 408: waiting state. The second kind of situation: go to step 409: the inquiry timer time is up; go to step 410: clear all reply flags to 0; go to step 411: send the inquiry message; go to step 412 again: activate the check timer; after that, go to step 413: enter the waiting state; the third situation: go to step 414: check the timer time is up; go to step 415: check the reply flag; those who have a reply are marked as "in contact", and those who do not have a reply are marked as "leaving"; after that , return to step 402: activate the inquiry timer.

As shown in Figure 5, it is an operation flowchart of call transfer when an extension user leaves the seat in the present invention; the extension user of each extension can set the processing mode of all incoming calls when leaving the seat through the extension. Its operation process: first, carry out step 501: the extension is on standby; then proceed to step 502: the extension user lifts the microphone to start setting; proceed to step 503: the incoming call can be set to be forwarded to the mobile phone of the extension user when leaving the seat; Step 504: You can set the call forwarding to another extension when you leave the seat; or go to step 505: you can set the call forwarding to the voicemail when you leave the seat; go to step 506: you can also cancel the call forwarding function when you leave the seat. After making these settings, proceed to step 507: the database will cancel the original setting and update the processing method of incoming call transfer when the extension user leaves the seat; proceed to step 508: put down the extension microphone at the extension user; proceed to step 509: the setting is completed, the extension Enter the standby state.

As shown in Figure 6, at last, when an extension calls, its processing flow is as follows: first, carry out step 601: switch is in standby state; Then carry out step 602: if receive an extension and have incoming call; Afterwards, carry out step 603: central The processor checks whether there is a corresponding portable bluetooth device, if not, proceed to step 604: the extension starts ringing; then proceed to step 605: activate the ring timer; then proceed to step 606: the switch is on standby; If there is a corresponding portable bluetooth device, then proceed to step 607: check the current contact status; if the corresponding portable bluetooth device is still "in contact", that is, the extension user is still on the seat, then proceed to step 604: the extension immediately Start to ring the bell; then, go to step 605: activate the ring timer; then, go to step 606: the switch is on standby. In step 607, it is checked that the corresponding portable bluetooth device has "leaved", that is, the extension user has left the seat, then proceed to step 608: check the call transfer mode of the extension in the database; then proceed to step 609: enter transfer Voice mailbox, go to step 610: transfer to another extension or go to step 611: transfer to a mobile phone; after that, go to step 612: switch standby state. Also, when the switchboard is on standby, the telephone bell has rang for a period of time, that is, step 613 is performed: the extension ring timer time is up; then step 614 is performed: the voice mailbox is transferred, and then step 615: the switchboard standby state is entered.
