As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. In the drawings, parts irrelevant to the description are omitted in order to clearly describe the present invention. Like parts are designated by like reference numerals throughout the specification.

1 is a block diagram of a voicemail service apparatus according to an embodiment of the present invention.

Referring to Figure 1, the voicemail service device according to an embodiment of the present invention,

The service management system 101, the service control system 102, the service performing exchange 104, the intelligent voice messaging device 105, the destination local exchange 107, and the calling local exchange 109.

The telephone network 106 connects the call from the instant-connect voicemail service sender 110 to the incoming call phone 108 and receives and forwards the service call generated at the incoming local exchange 107. A service performing exchange 104 is connected to the telephone network 106 to deliver an instant-connect voicemail service. The intelligent voice messaging device 105 is connected to the telephone network and the common line signal network 103 to provide guide broadcasting, digit collection, and voicemail. The common line signal network 103 is connected to the service performing exchange 104 and the intelligent voice mailbox device 105 to transmit service control information. The service control system 102 is connected to the common line signal network 103 to control a service call of an immediate connection voicemail box. The service management system 101 manages service data. The destination local exchange 107 receives the subscriber's subscriber phone 108 and generates an intelligent network for the voice mailbox incoming prefix. The outgoing local exchange 109 houses the outgoing telephone 110. Here, the service performing exchange, the destination local exchange, and the outgoing local exchange may be one exchange as necessary, and may be multiple exchanges as necessary.

The operation of the voicemail service apparatus according to the embodiment of the present invention having such a configuration will be described in detail with reference to FIG. 2 as follows.

First, any caller attempts to make a call to a subscription phone 108 registered as a voice mail using the phone 110. Then, the call is transferred to the destination local exchange 107 through the outgoing local exchange 109 (S1). In this case, it is assumed that the caller's telephone number, the called party's telephone number, and the voice mailbox incoming registration number are as follows.

Ex) Caller's phone number: 02-526-6052

Incoming subscriber's phone number: 02-526-6053

Voicemail forwarding registration number: * 88 1585

Then, the incoming local exchange 107 recognizes the call transfer call, which is a phone number registered in advance, and transfers the voice mailbox incoming registration prefix 1585 to the service performing exchange 104 (S2).

Next, the service execution exchange 104 transmits an initial detection operation (IDP) requesting an immediate connection voicemail service to the service control system 102 through the prefix 1585 (S3).

Then, the service control system 102 recognizes that it is an immediate connection voicemail service through the prefix 1585, acquires the subscriber number from the transfer number included in the initial detection operation (IDP), and then connects to the voicemail of the corresponding subscriber. In order to transmit the temporary connection establishment operation to the service performing exchange 104. At this time, the billing (FCI) operation and the BCSM case report request (RRBE) operation is transmitted together (S4).

Then, the service performing exchange 104 establishes a temporary call path between the calling local exchange 110 to which the caller's telephone 109 is connected and the intelligent voice messaging device 105 according to the request for the temporary connection establishment of the service control system 102. It is set (S5).

Then, if the temporary call path is normally set, the intelligent voice messaging device 105 transmits the auxiliary command request operation to the service control system 102 (S6).

Then, the intelligent voice messaging device 105 sends a voicemail connection announcement to the caller 108 according to the control signal PCUI of the service control system 1020 (S7).

Then, if the caller 108 is not disconnected (S9), the service control system 1020 connects to the voicemail service (S10).

Then, the user inputs the message by voice, and the intelligent voice messaging device 105 transmits the service result PCUI_RR to the service control system 102 (S11).

Then, the service control system 102 releases the temporary connection to the service performing exchange 104 (DFC) (S12), and transmits the analog end message (TC_END) to the intelligent voice messaging device 105 (S13). Release the temporary call path (S14).

Through the above process, it is possible to simultaneously use voicemail service in addition to call transfer service with simple button operation by using voicemail system interworking with intelligent network and intelligent network to call forwarding service subscriber provided based on exchange.

Therefore, through the embodiment of the present invention, the subscriber checks the voice message by using a voice mail service in addition to the transfer for business purposes, such as for receiving orders for holidays and nights, a message arrival notification function (sms, e-mail), and an external telephone. You can use useful features such as the mailbox.

On the other hand, the present invention is not limited only to the above-described embodiment, but may be modified and modified within the scope not departing from the gist of the present invention. Those skilled in the art will appreciate that various changes and modifications can be made without departing from the spirit and scope of the present invention.

As described above, in the embodiment of the present invention, a message arrival notification function (sms, e- You can use useful functions of mailbox such as mail) and voice mail check from outside.
