Description

Call separation routing method of exchange

The present invention relates to a call separation routing method of an exchange system, and more particularly, to a method capable of routing separately by a subscriber and a relay line type.

In general, the exchange has several Digit Analysis Tables (hereinafter referred to as "DATs") to accommodate multiple station numbers in the system. In other words, in case of subscriber, DAT is fixed to '0' and DAT number can be assigned from 0 to 100 for each incoming route. It is configured to vary the translation start point of the incoming code (Prefix) for each DAT to accommodate the DAT station number separately. When the regular wired subscriber 111 dials aaa, the number is translated based on the translation code of the DAT '0'. Then, the route information and the trunk line mounting information, etc. are obtained from the route number to set the call.

1 is a diagram illustrating a general call separation routing flow.

Referring to FIG. 1, reference numeral 10 in the figure denotes a subscriber unit, 20 is a source exchange, 30 is a relay exchange, and 40 is a power exchange. The subscriber unit 10 includes a general wired subscriber 11, an integrated service digital network (ISDN) subscriber 13, and a packet subscriber 15. When one of the subscribers dials a predetermined number, the first switch 20, which is the calling station switch, determines a route from the number. For example, in FIG. 1, when the general wired subscriber 11 dials aaa, the first exchanger 20 determines the route by referring to the route sequence shown in FIG. As shown in FIG. 2, the route sequence includes direct route information (DR) and eight bypass route information (AR). In case of general subscriber, it connects to R2 route called code ddd, and in case of ISDN subscriber, it is decided as ISUP route. Since the subscriber dialed by aaa is a regular wired subscriber, the subscriber is determined to be the incoming code ddd of R2 root. The called code ddd is the root sequence number of the first route table 35 of the second exchange 30. The second exchanger 30 receives the route sequence number ddd and determines the route with the incoming code fff of the R2 route that can go to the corresponding exchange. The third switching center 40 receives the incoming code fff and sets up a call to the subscriber. In case of ISDN subscriber, the call is established through the ISUP route in the same manner as the general wired subscriber. The packet subscriber also sets up a call in the same way as the subscriber via a separate packet route.

In order to allow ISDN subscribers to use ISUP relay lines, and general subscribers to use R2 relay lines, the incoming code is separated (aaa, bbb) for outgoing calls, and the first route table is used for relay calls. It was used separately by incoming broadcast. The packet subscriber should use the packet route, but because the packet routing is managed separately, the incoming code was created separately for both outgoing and relay calls.

Therefore, even in the same country, the incoming call was made separately for outgoing call, and during the call, the special route sequence had to be used. Thus, making and managing the receiving code separately causes a waste of the receiving code resources and makes the station number difficult to design, leading to confusion in operation as well as causing inconvenience to subscribers.

In addition, using a special route sequence has a problem of degrading overall call processing performance because it requires an area of about 0.1 seconds for each call.

In addition, since the packet subscriber handles routing separately, there is no concept of route sequence and special route sequence, and various network management functions cannot be used during normal routing, and there is a problem of always managing incoming code and route separately when routing. there was.

Accordingly, an object of the present invention is to provide a call separation routing method of an exchange which automatically routes the subscriber and the relay line type during routing.

In order to achieve the above object, the present invention provides a station number translation unit for performing a station number translation for a predetermined call request and selecting a route sequence for the translated station number, and a plurality of general wired subscriber route information and a plurality of comprehensive information. A number translation processor having a route sequence having route information for communication subscribers and having a route selector for selecting an appropriate route among the plurality of route information, and receiving a relay line occupancy request for the route selected by the route selector. In a call separation routing method of an exchange system comprising an outgoing call processing unit for setting up a call, the number translation unit performs a number translation on the call when a call request occurs from a general wire subscriber or a general information communication subscriber. Select a root and request routing in the corresponding route sequence of the route selector. In step 1, the route selecting unit receives the routing request and examines the requested call type to select a route for a general wired subscriber if a general wired subscriber and a route for a comprehensive telecommunication subscriber for a general telecommunication subscriber. Step 2 and, if the route is selected, characterized in that consisting of a third process for requesting the relay line occupancy of the route to the outgoing call processing unit.

3 is a block diagram of an exchanger to which the present invention is applied.

Referring to FIG. 3, reference numeral 110 denotes an incoming call processor, 126 is a Number Translation Processor (NTP), and 130 is an outgoing call processor. The incoming call processor 110 separates the call of the ISDN subscriber from the ISUP call processor 111, which handles the ISDN subscriber's call, the R2 call processor 113, which handles the call of the general wired subscriber, and the general wired subscriber call inputted through the relay line. It consists of a separating section 115. The ISUP call processing unit 111 or R2 call processing unit 113 requests translation of the digits of the digits for the call to the number translation processor 126 when a call is input. The number translation processor 126 includes a station number translation unit 121 and a route selection unit 123. When the incoming call processing unit 110 requests translation of a digit number from the incoming call processor 110, the station number translation unit 121 translates the station number of the digit. do. The station number translation unit 121 makes a routing request to the route selection unit 123, which is a routing control unit, with the route sequence number assigned to the translated called code (Prefix). The route selector 123 receives a route sequence number and selects an appropriate route from among routes assigned to the route sequence. In addition, the route selector 123 includes a route sequence having route information for general wired subscribers and route information for a general information communication subscriber, as shown in FIG. 6A, according to the first embodiment of the present invention, or according to the second embodiment of the present invention. Accordingly, as shown in FIG. 6B, the mobile terminal has a route sequence for a general wired subscriber, a route sequence for a general information and communication subscriber, and a route sequence for a packet subscriber, respectively. The outgoing call processor 130 connects a call input from an ISUP call processor 131 for processing a call of an ISDN subscriber, an R2 call processor 133 for processing a call of a general wired subscriber, and an ISUP call processor 131 or an R2 call processor 133 with a relay line. The relay line selector 135 is formed. The route selector 123 requests the occupation of the relay line to the ISUP call processor 131 or the R2 call processor 133 of the outgoing call processor 130 on which the outgoing relay line assigned to the selected route is mounted. The ISUP call processor 131 or the R2 call processor 133 attempts to occupy the outgoing relay line and notifies the route selector 123 of the failure in case of failure. The route selector 123 notified of the failure to occupy selects the next available bypass route and requests a bypass route.

4 is a view showing a call separation routing method according to a first embodiment of the present invention.

Referring to FIG. 4, the incoming call processor 110 separates the call splitter 115 from the call splitter 115 when the general wired subscriber or the general information communication subscriber requests the call setup, and the corresponding call processor of the ISUP call processor 113 and the R2 call processor 115. Switch to The switched call processing unit requests the number translation to the number translation processor 126 in step 401. The number translation processor 126 receives the number translation request through the station number translation unit 121. The station number translation unit 121 obtains an incoming code by performing a station number translation on the requested call in step 403. The station number translation unit 121 selects a route sequence assigned to the called code (Prefix) in step 405. If the route sequence is selected in step 405, the station number translation unit 121 requests routing to the route selector 123 in step 407. In step 409, the route selector 123 that has been requested for routing checks the type of the call. In step 411, the route selector 123 determines whether the call is a call requested by a general wire subscriber. If the call type is a call requested by a general wire subscriber, the route selector 123 proceeds to step 413 to select a route for a general wire subscriber. If the call type is a call requested by the general information communication subscriber, the route selector 123 proceeds to step 415 to select a route for the general information communication subscriber. When the route is selected in steps 413 and 415, the route selector 123 proceeds to step 417 and requests the outgoing call processor 130 to occupy the relay line. The charging call processor 130, which is requested to occupy the relay line of the route, attempts to occupy the relay line of the requested route, and determines whether the relay line is occupied in step 419. If the relay line is occupied successfully, outgoing call processor 130 sets the call. However, if the relay line is not occupied, the outgoing call processor 130 requires the route selection unit 123 to select the bypass route again. The route selection unit 123, which has been requested for this, repeats the process after step 411 and attempts to occupy the relay line of another bypass route.

5 is a diagram illustrating call separation routing according to a second embodiment of the present invention.

Referring to FIG. 5, when a subscriber requests a call setup using a predetermined dial number, the call separator 115 of the incoming call processor 110 receives the call setup request and according to the subscriber requesting the call, the ISUP call processor 111. Or switch to the R2 call processor 115. In response to the call formation request, the call processor requests the station number translation of the dialed dial number to the station number translation unit 121 of the number translation processor 126 in step 501.

When the station number translation unit 121 is requested to translate the station number, the station number translation unit 121 checks the originating subscriber type that requested call formation. If the test result is determined to be a general wired subscriber in step 505, the station number translation unit 121 selects a route sequence for a normal wired subscriber, and proceeds to step 515 to output a route sequencer for a normal wired subscriber to a route selector 123. Requires rooting On the other hand, if it is determined that the originating subscriber type test result is a comprehensive information communication subscriber, the station number translation unit 121 selects a route information for comprehensive information communication, and proceeds to step 515 and outputs the route information number for the comprehensive information communication to the route selector 123. Requires rooting If the check result is determined to be a packet subscriber, the station number translation unit 121 selects a packet communication route sequence, and outputs the packet communication route sequence number to the route selector 123 in step 515 to request routing with the selected route sequence. .

The route selector 123 receives the route sequence number from the station number translation unit 110 in step 517 and examines route information of the route sequence to select efficient routing. When the routing is determined for the requested call setup, the route selector 123 requests the relay line occupancy of the selected route to the corresponding call processor among the ISUP call processor 131 and the R2 call processor 133 of the outgoing call processor 130 in step 519.

When the relay line occupancy request of the route selected from the route selector 123 is input, the corresponding call processor of the outgoing call processor 130 attempts to occupy the relay line of the selected route through the relay line selector 135. After the relay line occupation attempt, the call processor determines whether the relay line occupation is successful in step 521. If the relay line is occupied successfully, a call is set, and if it is not successful, the route selector 123 notifies that the selected relay line has failed, and requests to set the route again. The process after the reset request of the route is performed in the same manner as the process after the step 517.

As described above, the present invention can automatically design the incoming code by automatically checking the transmission type at the exchange and routing separately, so that the design can be efficiently performed when designing the station number, and there is an advantage in that a lot of space is created in the station number design.

In addition, the present invention has the advantage that the call setup time is shortened because there is no need to write a special route sequence.

In addition, the present invention has the advantage that the packet subscriber can also use a variety of general routing functions, such as separate routing or network management, such as EHr if the separate route to the packet routing.
