The present invention relates to a telephone usage limiting device of a corporate communication network and a control method thereof, and in particular, a telephone water supply information management module in a final private exchange which transmits and receives a telephone signal with an external communication network via a plurality of private exchanges. The present invention relates to a telephone usage limiting device of a corporate telecommunication network and a method of controlling the same, which analyzes CID information indicating an outgoing call information included in an outgoing call message and outputs water supply information.

In general, as the industrial society develops, information communication systems are widely used to transfer data from one point to another desired more appropriately and quickly. Such communication systems are usually homogeneous or heterogeneous communication devices which are geographically dispersed. In most cases, information devices are connected to a network to enable sharing and communication of resources. In the network, a switch is usually used to exchange information converted into an electrical signal with a counterpart, and is divided into a subscriber transmission connecting a subscriber and an exchange and a transmission between stations connecting an exchange period.

Particularly, various types of systems are currently developed and used in the exchange system for subscriber transmission in terms of large facility capacity, such as a simple telephone system for a building or a small subscriber, such as a key-phone system. system) is now widely used. However, in recent years, due to the increase in the amount of communication within a single enterprise, it is frequently used to connect multiple private exchanges to each other in the final private exchange connected to an external communication network. Therefore, an apparatus for limiting specific telephones according to the use water level is provided and used in an enterprise communication network composed of a plurality of private exchanges as described above.

Then, referring to FIG. 1, a conventional telephone communication limiting device of a corporate communication network as described above, by interfacing a call setting message of a specific telephone 71 transmitted from a plurality of private exchanges 70A-B connected to an internal communication network Receives the call setup message signal of the input relay line block 72 outputted with the water supply information of the corresponding line and the other private switch 70A processed by the input relay line block, allocates a channel, and then applies the corresponding signal. The output water line block 74 which outputs to the external PSTN network 73 and searches and processes the telephone use restriction function using the input water supply information, and the telephone water supply which previously stored the water supply information output from the output power line block 74. A call restriction analysis block 75 for comparatively analyzing in the restriction database (hereinafter referred to as db) and outputting the telephone call restriction information to the output relay line block 74.

Then, another end of the output trunk line block 74 is connected to an extension subscriber block 77 for processing the call signal of the telephone subscriber 76 of the extension subscriber.

On the other hand, referring to the operation of the conventional telephone use limiting device of the corporate communication network, first, a specific telephone device provided inside the other private exchange 70A connected to the private exchange 70A connected to the PSTN network 73 When the call is requested at 71, the call is input to the input relay line 72 of the private exchange 70A connected to the PSTN network 73 via the corresponding private exchange 70A. Then, the input trunk line block 72 interfaces the call setup message of the specific telephone 71 transmitted from the other private exchange 70A and outputs it to the output trunk line block 74 together with the water supply information of the corresponding line. The output trunk line block 74 receives the call setup message signal of the other private exchange 70A processed by the input trunk line block 72 and then sends the input water supply information to the transmission limit analysis block 75. Enter it. In addition, the transmission restriction analysis block 75 compares the water supply information output from the output relay line block 74 in the previously stored telephone water supply db, and outputs the telephone usage restriction information to the output relay line block 74. Then, the output trunk line block 74 is to limit the transmission or non-transmission of the call message input from the input relay line block 72 according to the telephone call restriction information input from the transmission restriction analysis block 75 or call or not. Decide if you want to connect. For example, the output trunk line block 74 does not allocate a call channel when the telephone usage restriction information for the current call message input from the transmission restriction analysis module 75 restricts telephone usage, while allowing telephone usage. If the message is assigned to the channel and then output the corresponding signal to the external PSTN network (73).

However, the conventional telephone communication restriction device of the enterprise communication network as described above includes all the call usage restrictions of the extension subscriber's call message including the call message of another private exchange which is input to the private exchange connected to the PSTN network. Since it is determined depending on the subscriber's water supply, it is executed irrespective of the telephone call water supply of the first caller inputted through a number of other private exchanges. For example, when expensive private exchanges are connected to each other, the restriction function for the outgoing call cannot be properly handled, thereby reducing the functionality of the telephone access limiter.

In addition, after the water supply information search output step (S3) to proceed to the usage information search step (S4) and the output relay line module of the private exchange connected to the PSTN network by using the water supply information of the specific telephone of the other private exchange inputted Retrieves the use of the telephone from the telephone water supply restriction database. After the usage information retrieval step (S4), the process proceeds to the telephone use permission determination step (S5) to determine whether the water supply of the specific telephone is the usage allowable phone. At this time, when the water supply of the specific telephone is not the telephone number allowed as a result of the determination in the telephone use permission determination step (S5), the current step is terminated and the call is restricted. However, if the water supply of the specific telephone is the acceptable telephone as a result of the determination during the telephone use permission determination step (S5), the process proceeds to the call processing execution step (S6) and the channel on the call message of the specific telephone of the other private exchange which is permitted to use the telephone. To execute PSTN network and call processing.

That is, when a call is requested from a specific telephone 2 provided in the other private exchange 1A connected to the private exchange 1C connected to the PSTN network 5, the call message includes a CID method. A telephone number is also included and input to the input relay line module 3 of the private exchange 1C connected to the PSTN network 5 via the corresponding private exchange 1A. Then, the input trunk line module 3 interfaces a call setup message including a CID telephone number of a specific telephone 2 transmitted from another private exchange 1A-C to search for water supply information for the corresponding line. CID information (telephone number) is input to the telephone water supply information management module (4) to retrieve the actual water supply information for the telephone. The telephone water supply information management module 4 uses the CID information (telephone number) signal inputted from the input relay line module 3 to pre-build water supply information of the first outgoing call of the other private exchange 1A-C. Search the water supply management DB and the water supply information of the corresponding phone is output to the input relay line module (3). Then, the input trunk line module 3 sends the actual water supply information for the specific telephone of the other private exchange 1A-C retrieved from the telephone water supply information management module 4 together with the call message to the output trunk line module 6. Output it.

Accordingly, the output trunk line module 6 receives the call setup message signal of the other private switch 1A-C processed by the input trunk line module 3, and then transmits the input water supply information. ). In addition, the transmission restriction analysis block (1) compares and analyzes the water supply information output from the output relay line module 6 in the pre-stored telephone water supply db, and outputs the telephone usage restriction information to the output relay line module 6. Then, the output trunk line module 6 is to limit the transmission of the call message input from the input trunk line module 3, that is, the telephone use according to the telephone call restriction information input from the transmission restriction analysis block 7 or call Decide if you want to connect. For example, the output trunk line module 6 does not assign a call channel when the telephone usage restriction information for the current call message input from the transmission restriction analysis module 7 restricts telephone usage, while allowing telephone usage. If the message is to be assigned to the channel and then output the signal to the external PSTN network (5).

Meanwhile, another embodiment of the present invention includes a call setup message including a CID telephone number of a specific telephone 2 transmitted from another private exchange 1A-B inputted to the input trunk line module 3. In addition to the CID information (phone number of the first outgoing call), it directly configures and transmits the water supply information of the first outgoing call.

Therefore, in another embodiment of the present invention as described above, when a call message of a specific telephone of another switch 1A-B is inputted to the switch 1C connected to the PSTN network 5, the water supply information of the first outgoing call is directly received. Since the included home message is also transmitted, the input relay module of the private exchange connected to the PSTN network does not need to perform a separate search for the water supply information. The actual water information included in the received home message is directly transferred to the output relay module. Since it is necessary to transmit, it is not necessary to provide a separate configuration as the telephone water supply information management module 4 of the embodiment, and the rest of the operation is the same as the operation of the embodiment.

As described above, the present invention includes a telephone water supply information management module in a final private exchange that transmits and receives a telephone signal with an external communication network through a plurality of private exchanges, and includes outgoing telephone information included in a home message originated by an original originating telephone. By analyzing the CID information and outputting the water supply information, the final private exchange can limit the telephone usage by using the water supply information according to the CID sent from the first outgoing telephone. Has the advantage of maximizing.
