Abstract

The present invention relates to an automatic routing method in a switching system. In particular, when a long-distance operator code frequently used by a wireless subscriber is registered, even if a called number without a carrier code is received from the wireless subscriber, only the called number is applicable. The present invention relates to an automatic routing method in an exchange system for automatically routing to a trunk group for a long distance carrier.

Conventionally, when a call request originating from a wireless subscriber is to be processed through a long-distance provider, the wireless subscriber must dial the called party number with the carrier code, so that the call is routed to the trunk group of the long-distance carrier through the translation of the number by the called party. In addition, there was an inconvenience of having to dial the operator code to the called party number, even for the operator frequently used by the wireless subscriber.

According to the present invention, when a long-distance carrier frequently used by a wireless subscriber is registered, if a call is to be processed through a long-distance operator by translating a destination number when a call occurs in an exchange system, the operator code registered by the calling subscriber is analyzed. Automatic routing to the trunk group makes it easy to dial the destination number of the wireless subscriber.

Description

Automatic Routing Method in Switching System

The present invention relates to an automatic routing method in a switching system. In particular, when a long-distance operator code frequently used by a wireless subscriber is registered, even if a called number without a carrier code is received from the wireless subscriber, only the called number is applicable. The present invention relates to an automatic routing method in an exchange system for automatically routing to a trunk group for a long distance carrier.

Conventionally, when performing the service processing performed in the switching system, it is configured to perform differential processing based on the caller group belonging to each communication service provider, and the call processing, the relay line connection, and the announcement broadcast are processed separately for each caller group. That is, when a call originates from a caller, it checks which subscriber group (the subscriber of which carrier) the caller is connected, and relay line connection, announcement, billing format, statistical format, supplementary service and network operation provided for the subscriber group. It is configured to check the overall data and the like from a predetermined data table and perform differential processing.

The joint utilization processing operation of the exchange system is performed in the same order as in FIG.

First, when a call is generated from a caller to make a call to a mobile and wired subscriber (step S11), the switching system receives a called number for the mobile and wired subscriber from the caller (step S12) and then makes a call to the caller. Group belonging is recognized (step S13).

Then, the exchange system executes the authority check on the caller to determine whether the authority check fails (step S14), and if the authority check on the caller does not fail, the exchange system sends the caller from a predetermined table. It is confirmed whether a specific announcement broadcast is added to the group (step S15).

At this time, if it is determined that the announcement is not added to the group to which the caller belongs, the switching system connects a trunk group preset for the group to which the caller belongs from a predetermined table (step S16). If it is confirmed that the announcement is added to the group to which the group belongs, the switching system connects the specific announcement to the caller (step S21), and then connects a trunk group preset for the group to which the caller belongs from a predetermined table. Perform the operation of S16.

After that, the switching system translates the called number received from the caller (step S17), recognizes the connection type for the caller from the predetermined data table (step S18), and then processes the call processing for the translated called number. The caller is connected to the called party through the connected trunk group by performing (step S19).

On the other hand, in step S14, if the authority check for the caller fails, after translating the called party number of the customer information center assigned to each caller group from the predetermined data table (step S20), the call processing operation of step S19 is executed. By performing the call processing on the forwarding number of the translated customer information center, the caller is informed that the caller cannot connect to the customer information center and make a call.

As described above, conventionally, when a call is generated from a caller, the caller is identified to which subscriber group (which carrier of which carrier) and the relay line connection, announcement, and network operation data provided for the subscriber group. The differential processing is performed by checking from a predetermined data table, so that a single exchange system can be used jointly by several communication providers.

However, conventionally, when a call request originating from a wireless subscriber is to be handled through a long-distance provider, the wireless subscriber must dial the called party number with the carrier code to transfer to the trunk group of the long-distance carrier by translating the number by the called party number. Because of routing, there was an inconvenience in that the operator frequently dials the operator code in the called number even for the operator frequently used by the wireless subscriber.

The present invention is to solve the problems described above, the object of the present invention is to register a long-distance carrier frequently used by the wireless subscriber, if the call is to be generated in the exchange system when the call is to be processed through the long-distance operator In other words, it analyzes the operator code registered by the calling subscriber and automatically routes it to the trunk group.

A feature of the present invention for achieving the above object is a method for automatic routing in an exchange system, the process of receiving a called number when the call is generated and receiving the operator code for the calling subscriber; Searching for a provider code list table by translating the called number and identifying a call that needs to be processed through a long distance operator; Checking whether there is a service provider code corresponding to the calling subscriber and extracting information on the service provider code; Automatic routing process to select the trunk group for the registered long-distance carrier to provide a call service to the calling party.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 2, the configuration of the switching system according to the present invention includes a wireless access switching processor 21 (Access Switching Processor-Wireless), a location registration processor (22) and a number relay processing unit. (23; Number Translation Processor) and a plurality of trunk connection switching processing units (24-1 to 24-n; Access Switching Processor-Trunk).

The wireless access switching processor 21 connects the wireless subscriber to perform a switching function for signals input and output to and from the wireless subscriber, and the location registration processor 22 registers information on the wireless subscriber included in the corresponding switching system. By performing the calling query, the operator code for the calling subscriber is received and provided to the number relay processing unit 23.

The number relay processor 23 analyzes the incoming number from the wireless subscriber and selects a specific trunk group to route to the counter switching system where the number is located. Each trunk connection switching processor 24-1 to 24-n is a counter switching system. Switch each trunk in the trunk group associated with it.

The automatic routing operation in the switching system according to the present invention configured as described above is performed in the same order as in FIG.

First, when a user of a communication terminal registers a corresponding terminal to a predetermined communication provider, the user registers an operator code for a long-distance carrier that he frequently uses in addition to various information about the corresponding terminal to a home location register (HLR).

Accordingly, when a call is generated from the wireless subscriber of the switching system, i.e., the calling subscriber to the mobile and wired subscriber (step S31), the number relay processor 23 of the switching system receives the wireless access switching processor 21 from the calling subscriber. After receiving the incoming call number (step S32), the origin registration query is performed to the location registration processing unit 22 to receive a carrier code for the calling subscriber from the HLR (step S33).

Then, the number relay processor 23 translates the incoming number received from the wireless subscriber (step S34), and confirms whether the call request call of the calling subscriber should be processed through the long-distance operator (step S35).

If the call request is a call that needs to be processed through a long-distance operator, the number relay processing unit 23 searches the operator code list table (step S36) to check whether there is a provider code corresponding to the calling party. Step S37).

If the operator code corresponding to the calling party exists in step S37, that is, if the operator code for the long-distance carrier frequently used by the calling party is registered, the number relay processing unit 23 corresponds to the corresponding calling party. Search the information storage area for the operator code, extract the information (operator name, trunk group assigned to the operator, routing method) about the operator code (step S38), and then register by the corresponding calling subscriber using the extracted information. The automatic routing process is performed to select the trunk group for the long distance operator (step S39).

Then, the number relay processor 23 performs a call processing operation on the called number from the calling subscriber (step S40), thereby providing call service to the calling subscriber.

On the other hand, in step S35, if the call is not a call that needs to be handled by the long-distance operator, the number relay processing unit 23 selects a trunk group for the translated number (step S41), and then applies the corresponding trunk group through the selected trunk group. By performing the operation of step S40 for performing call processing for the called number, the call service is provided to the corresponding calling party.

In addition, in step S37, if the operator code corresponding to the calling party does not exist, that is, if the operator code for the long-distance carrier frequently used by the calling subscriber is not registered, the number relay processing unit 23 Search the provider code table provided by the switching system by default (step S42), select the trunk group for the provider code provided by the corresponding switching system (step S43), and then process the call for the called party number through the selected trunk group. By performing the operation of step S40 to perform a call service to the calling party.

As described above, when a user of a wireless terminal registers with a carrier and registers an operator code for a long-distance carrier desired by the wireless subscriber, when a call is generated from the wireless subscriber, the carrier code is used. Since the routing process selects a trunk group allocated to each long-distance carrier without manipulating or additional translation of the called party number, even if the wireless subscriber dials without including the operator code in the called party number, the calling service can be provided to the corresponding wireless subscriber. .

As described above, in the present invention, when a long-distance operator frequently used by a wireless subscriber is registered, if the call is to be processed by a long-distance operator by translating the called number when a call occurs in the exchange system, the registered operator is registered by the calling party. The code is analyzed and automatically routed to the trunk group, making it easy to dial the destination number of the wireless subscriber.
