Abstract

PURPOSE: A method for connecting a speech path between a voice mail system and subscribers is provided to cancel a speech path connected between the voice mail system and an exchange, and to connect a speech path between an originating subscriber and a receiving subscriber in the exchange, and thereby not allocating an unnecessary speech path to efficiently connect the speech path between the subscribers. CONSTITUTION: If a call with a message storing subscriber is requested, an exchange stores speech path data and time switch information and simultaneously refers to information on an originating subscriber and a receiving subscriber, then sets up a speech path for calling. If a response relating to the calling is generated, the exchange connects the speech path between the originating subscriber and the receiving subscriber, and simultaneously cancels a speech path between a voice mail system and the exchange. The step of performing the calling comprises as follows. The voice mail system confirms whether a call is attempted with the message storing subscriber or whether the subscriber is directly called. The voice mail system attempts an origination by including a personal number of the originating subscriber who attempts the call. The exchange confirms whether the call includes the personal number, and stores the speech path data and the time switch information. The exchange refers to the information on the originating/the receiving subscribers to confirm whether the subscribers are available subscribers. The exchange attempts a calling and simultaneously sets up a speech path for informing the originating subscriber of the receiving subscriber calling.

Description

Method of Connecting Communication Path between Voice Mail System and Subscriber}

The present invention relates to a method for accessing a call path between a voice mailbox device and a subscriber, and in particular, in a supplementary service of a voice mail device for a call with a message storage subscriber, a call path is formed between a corresponding voice mail device and an exchange without configuration of a call path. The present invention relates to a method of accessing a call between a voice mail apparatus and a subscriber.

In a general Code Division Multiple Access (CDMA) network, when a subscriber wants to make a call with a mobile subscriber by performing an additional service by connecting to a voice mailbox device, the subscriber can use the call path and voice mailbox device to access the voice mailbox device. A total of two or more call paths are required, such as a call path configured when making a call with a subscriber.

At this time, the structure allocated to the two call paths between the exchange and the voice mailbox device is configured as shown in FIG. 1, and the operation of configuring the call path will be described as follows with reference to FIG. 1.

First, in order to access the voice mailbox device 11, there is a method in which a mobile subscriber directly dials an access number for dialing the voice mail device 11 or dials his / her own number. By selecting one of them and accessing the voice mailbox device 11, a call path is formed between the mobile subscriber and the voice mailbox device 11, which causes the mobile subscriber to provide By listening to the announcement broadcast it is possible to perform the additional service provided by the voice mailbox device (11).

Therefore, when the connected subscriber wants to call the message storage subscriber from among the additional services provided by the voice mailbox apparatus 11, for example, to perform the additional service, the voice mailbox apparatus 11 sends a call to the called subscriber. Try.

Then, when the subscriber who attempted the call and the called party are mobile subscribers, the exchange 12 receiving the message sent by the voice mailbox device 11 performs information inquiry of the called party. And, if the normal subscriber as a result of the inquiry attempts the call of the called party, upon receiving a response from the called party establishes a call path between the called party and the voice mailbox device (11).

Accordingly, the call path between the calling subscriber and the voice mailbox device 11 is configured, and when the configuration of the call path between the calling subscriber and the voice mailbox device 11 is completed, the voice mailbox device 11 connects the two call paths internally. It allows you to make a call between subscribers. At this time, the exchange 12 constitutes two currency paths.

As described above, in the conventional technology, when a subscriber connected to a voice mailbox device performs an additional service, the subscriber connects to more than necessary call paths, so that congestion of the call may occur, and because the subscriber occupies more call paths than necessary, There was a consuming problem.

The present invention is to improve the method of accessing the call path between the mobile subscriber and the voice mailbox device in the CDMA network in order to solve the problems described above, that is, the mobile subscriber is dialed out to access the voice mailbox device and again the voice mailbox When a device originates and configures a call with a subscriber, the voice mailbox device and subscriber are configured to save a limited call path between the voice mailbox device and the exchange by configuring the subscriber-to-subscriber path without configuring the call path between the voice mailbox device and the exchange. To provide a connection method between calls, there is a purpose.

The present invention for achieving the above object is a call path between the voice mailbox device and the subscriber comprising the step of providing an additional service by configuring a call path between the subscriber and the voice mailbox device in accordance with the subscriber's voice mailbox device connection request An access method comprising the steps of: storing data and time switch information in a call at a switch when a call request is made with a message storage subscriber, inquiring information of a calling and receiving subscriber, setting up a call path, and calling the call; And in response to the call, disconnecting the call path between the calling subscriber and the called party from inside the exchange and releasing the call between the voice mailbox device and the exchange.

In this case, the calling process may include: checking a case where a voice mailbox device attempts to make a call with a message storage subscriber or calls a subscriber directly; Attempting to make a call by including a unique number of the calling subscriber who attempted the call in the voice mailbox device; Identifying, at the exchange, whether the call includes the unique number and storing data and time switch information in a call; Checking the information of the calling subscriber and the called subscriber at the exchange to determine whether the subscriber is a valid subscriber; And attempting to call the subscriber at the exchange and establishing a call path for informing the calling subscriber that the called subscriber is busy. The deconfiguring of the call line may include: checking whether a response is received from the called party after the exchange generates a ring tone to the called party; Identifying whether the call includes the unique number and connecting a call path of an outgoing subscriber and a call path set in a called party call in an exchange; And releasing the time switch allocated between the voice mailbox device and the switch and releasing the time switch of the subscriber directly connected to the voice mailbox device. Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

According to an embodiment of the present invention, a structure for accessing a call path between a voice mailbox device and a subscriber is configured as shown in FIG. 2, and another subscriber is connected to the voice mailbox device 21 to perform another service. If you want to make a call and make a call via 21, establish a call path that is configured more than necessary by directly setting the call path through the corresponding exchange 22 without configuring the call path between the voice mail device 21 and the exchange 22. It is made to save.

Referring to the flowchart of FIG. 3, a method for accessing a call between a voice mailbox device and a subscriber according to an embodiment of the present invention is as follows.

First, in order for a mobile subscriber to access the voice mailbox device 21, there is a method of directly dialing an access number for dialing the mobile mailbox device 21 or dialing its own number. By selecting one of the connection method of the connection to the voice mailbox device 21, the call path between the mobile subscriber and the voice mailbox device 21 to perform the additional service provided by the voice mailbox device 21 (Step S1).

In this case, the mobile subscriber accesses the voice mailbox device 21 and attempts to make a call with the subscriber who stored the message during an additional service or directly calls the subscriber (step S2). 21 includes the unique number of the calling subscriber who attempted the call or call and attempts to make a call to the exchange 22 side (step S3).

Then, the exchange 22 receiving the message sent from the voice mailbox device 21 confirms whether the call includes the unique number (step S4) and establishes a call path data for connecting a call path with a subscriber of the called party. (Step S5), and also stores time switch information between the voice mail device 21 and the switch 22 for informing the calling subscriber of an announcement broadcast generated while calling the called party. (Step S6).

In addition, the switch 22 inquires the information of the calling subscriber and the called subscriber to determine whether the subscriber is a normal subscriber or an abnormal subscriber (step S7). (Step S8), and establishes a call path to inform the calling subscriber that the called subscriber is in call (step S9).

Accordingly, when the called subscriber hears and responds to a ring tone, the switch 22 receives a response from the called subscriber (step S10) and confirms whether the corresponding call includes a caller's unique number (step S11). Find a call path connected to the voice mailbox device 21 and connect the call path connected to the voice mailbox device 21, that is, the call path set in response to the called subscriber and the call path of the stored calling party. S12). That is, the exchange 22 connects the call path between the calling subscriber and the called subscriber.

Then, the connection of the time switch allocated for the calling subscriber between the voice mail device 21 and the exchange 22 and the call set to the call of the called subscriber are released (step S13), and the voice mail device ( The time switch of the subscriber directly connected to 21) is also released (step S14). That is, it releases the communication path connected between the voice mailbox device 21 and the exchange 22.

In this way, a call can be saved between the calling subscriber and the called subscriber without the configuration of the call path between the voice mail device 21 and the switch 22, thereby saving a call path.

As described above, according to the present invention, in the call path between the voice mailbox device and the subscriber, the call path between the voice mailbox device and the exchange is released, and the call path between the calling subscriber and the called party is connected inside the switch. By not assigning the call path, the channel can be effectively applied to the subscriber.
