In FIG. 1, a plurality of base station controllers (BS: C1 to Cn) are coupled to the switch 100, and a plurality of base stations (BS) (B: B1 to Bn) are respectively coupled to the base station controller C. Will be combined. In addition, each base station (B) is coupled to a plurality of terminals (M) through the airwave transmission network, wherein the base station (B) and the terminal (M) is combined by a TDMA or CDMA scheme. In addition, the switch 30 is coupled to a plurality of exchanges through a relay line, such as an E1 or T1 link, and is also connected to a public switched telephone network (PSTN) or an integrated services digital network (ISDN) or other mobile communication network through a predetermined gateway. Combined with.

In the drawing, reference numeral 110 denotes a home location register (HLR) for storing various information related to service subscribers subscribed to the corresponding mobile communication network. The home location register 20 includes a plurality of fields for storing a subscriber number, a terminal unique number, subscriber usage information, additional service information, terminal current location information, authentication information, and the like.

In addition, the visitor location register 101 is provided at the exchange 110, and the visitor location register 101 has the home location register 110 corresponding to the subscriber existing in the jurisdiction of the corresponding exchange 100. ) 'S registration information will be saved.

In addition, the switch 100 executes call connection control based on call request information received from the base station controller C. In particular, when the called number included in the call request information has an identification number, for example, ″ * ″ Next, it is determined that the current called number is call connection information, and the predetermined call request information is controlled by the service switching part 120 in the intelligent network which will be described later. In addition, the call request information at this time includes the calling number, call connection information (called number) and the location information of the calling subscriber. At this time, the call request information is controlled based on the ISUP protocol.

In FIG. 1, reference numeral 120 denotes a service switching part (SSP) 120, and 130 denotes a service control part (SCP) 130, which constitutes an intelligent network. . The service switching part 120 and the service control part 130 are Nos. 7 Signaling is combined. In addition, the service switching part 120 is coupled with a local exchange, that is, the exchange 100 through an E1 or T1 relay line and an ISUP protocol, and thus the service switching part 120 and the service control part 130. The intelligent network is configured to provide an automatic call connection function in combination with the mobile communication network including the switch 100.

In particular, the service control part 130 in the above configuration is provided with the automatic call connection information to provide for each service subscriber. At this time, the call connection information is stored in the location information of the service subscriber, that is, the base station (B1) location information and the automatic call connection number and the called number associated with the call connection number of the area where the service subscriber exists. Here, the call connection number is a number for the subscriber to access a specific company or a specific business, for example, ″ 100 ″ for a Chinese restaurant, ″ 110 ″ for a pizza restaurant, and ″ 120 ″ for a supermarket. The number will be assigned. In addition, the called number is the actual telephone number (called number) of the specific company, which is registered with a maximum of one base station. For example, in response to the base station ″ B1 ″, only one telephone number of a Chinese restaurant, a pizza restaurant, and a supermarket is stored.

When the service switching part 120 receives an information message including call connection information, for example, a calling number, a call connection number, and a caller location information from the local exchange 100 through the ISUP protocol, the service control part 130 is provided. After reading the called number corresponding to the call connection number based on the call connection number and the caller location information, the call connection process is executed based on the called number. Of course, in this case, the call connection control process is executed by the service control part 130 as in the normal intelligent network.

Next, the operation of the above apparatus will be described in more detail.

When a subscriber within a jurisdiction of any base station, for example base station B1, dials ″ * 100 ″ to call a Chinese restaurant in the area, for example, the call request signal is transmitted to the base station B1 and the base station controller C1. It is connected to the exchange 100 through the).

On the other hand, in the exchange 100, call connection processing is executed based on the called number of call request information transmitted from the base station controller C1. If the called number is a number beginning with ″ * ″, the ISUP is performed. According to the protocol, the call request information is transmitted to the service switching part 120 in the intelligent network and the allocation process of the relay line channel is executed. In addition, the call request information includes the calling number, the called number, the location information of the subscriber and the like as described above. The subscriber location information may be provided from the base station B1 to the switch 100 and may be read from the visitor location register 101 based on the calling number at the switch 100.

Subsequently, in the intelligent network, the service switching part 120 transmits the call request information from the switch 100, that is, the local corrector, to the service control part 130, and the service control part 130 calls the call. Based on the calling party's location information and call connection information included in the request information, the actual incoming subscriber number of the Chinese restaurant in the area where the calling party is located is read from the internal database, and then the service is switched The part 120 is controlled to execute the call connection process.

Thus, the calling subscriber can dial any Chinese restaurant in the region from anywhere in the country just by dialing ″ * 100 ″.

On the other hand, in the above embodiment there is a disadvantage that the calling subscriber must know the call connection number of the company or industry to which he wants to call.

FIG. 2 is a system configuration diagram illustrating an automatic call connection device in a communication system according to another embodiment of the present invention in consideration of the above circumstances, and the same reference numerals are added to parts substantially the same as in FIG. 1 in FIG. 2.

In FIG. 2, an intelligent peripheral (IP) 230 is added to the service switching part 220. The intelligent peripheral device 230 is physically coupled to the service switching part 120 through a predetermined relay line and, for example, No. 7 Signaling and ISUP are coupled together. In addition, although not shown in detail in the drawing, the intelligent peripheral device 230 is coupled to the service control part 130 by a predetermined physical link. 7 It is combined through the intelligent network protocol. The intelligent peripheral device 230 is provided with a plurality of voice recognition module. And, the number of such voice recognition module will be appropriately set according to the number of channels with the switching part 220.

The intelligent peripheral device 230 interprets the voice signal input from the service switching part 220 through the predetermined relay line channel according to the control signal from the service control part 210 and converts the corresponding recognition data into the service control part ( 210). At this time, as the recognition data, for example, the coded data pre-assigned is used, such as "100" for a Chinese restaurant or "200" for a pizza restaurant.

The service control part 210 searches an internal database based on the code data transmitted from the intelligent peripheral device 230, reads the actual telephone number corresponding to the code data, and then switches the service on the basis of the code data. The part 220 controls switching of the calling subscriber to the called party that he wants by switching control.

In the above system, the calling subscriber provides a function of requesting a business of his / her desired type by voice, and a predetermined contract number, for example, ″ * 123 ″ is used between the system and the user. That is, when the calling subscriber wants to make a call using a voice to a Chinese restaurant existing in the area, for example, the caller presses ″ * 123 ″ using a dial button of the terminal M owned by the calling subscriber. Then, the above input number is transmitted to the interleaver 100 through the same method as the conventional method, and the switch 100 is based on this when the called number transmitted from the terminal M is ″ * 123 ″. After generating predetermined call request information to the service switching part 220 in the intelligent network. Of course, in this case as well, the calling number and the calling party location information are added to the call request information.

On the other hand, the call request information transmitted from the switch 100 as described above is to be transmitted to the service control part 210 through a conventional method. Subsequently, when the called number of the call request information is ″ * 123 ″, the service control part 220 first controls the service switching part 220 to connect the terminal M and the intelligent peripheral device 230 with the line combination. In addition, the intelligent peripheral device 230 transmits a command to recognize the input voice. Of course, in this case, it may be desirable to provide a voice prompt function in the service switching part 220 to provide a guide message to the calling subscriber, for example, `` Please tell the name of the desired business ''. In this case, in order to improve the voice recognition rate of the intelligent peripheral device 230, it may be desirable to press a specific button after finishing the voice input, such as ″ press the star after saying the name of the desired business place ″.

When the calling subscriber performs the voice input with respect to the guide message, the intelligent peripheral device 230 decodes the input voice and transmits the code data corresponding to the decoded result to the service control part 210. . The code data at this time also includes a case where the voice recognition fails or the corresponding business is not registered in advance.

Subsequently, when predetermined code data is input from the intelligent peripheral device 230, the service control part 210 searches the database based on the input code data and the caller location information that has been transmitted from the switch 100. You will read the actual phone number you wanted. For example, the code data input from the intelligent peripheral device 230 indicates a Chinese restaurant, and when the caller's location is the A region, the telephone number of the Chinese restaurant located in the A region is read. At this time, the service switching part 22 is controlled based on the read phone number to control line connection between the caller and the corresponding business.

In addition, if the code data input from the intelligent peripheral device 230 is error code data indicating the failure of speech recognition or error code data indicating that there is no code data corresponding to the voice recognition result, the service switching part 220 may be used. Execution control of the voice guidance function to guide the caller to enter the name of the business once again or to perform the announcement that there is no corresponding business.

In the above embodiment, the caller enters the name of the business by voice, so that he / she can make a call to the desired business. Therefore, it is possible to solve the inconvenience that the caller needs to know the code number corresponding to each business.

In addition, in the above embodiment, the service control part and the service switching part have only been described in which the caller automatically executes the call connection to the desired place. However, during the call waiting time after the call connection is executed, that is, the ringback tone (Ring) back tone) provides voice announcements in the service switching part 220 or a separate announcement via a separate intelligent peripheral, e.g. "Thank you for using our business". It is also possible. Such voice guidance is described in detail in Patent Application No. 99-41041 filed by the present applicant, so a detailed description thereof will be omitted.

The present invention is not limited to the above embodiments, and various modifications can be made without departing from the technical scope of the present invention, and the present invention may be limited only by the contents described in the claims.

For example, in the above embodiment, a case where the present invention is applied to a mobile communication network has been described as an example, but the present invention can be applied to a PSTN network or other communication networks in the same manner.

As described above, according to the present invention, an automatic call connection apparatus in a communication system that enables a user to perform communication using the same phone number or voice regardless of a location where a user requests a call for a specific destination. It can be realized.
