Description

How to handle FAC call at exchange

The present invention relates to FA supplementary service call processing in an exchange. In particular, when controlling a call by calling several subscribers simultaneously, the first subscriber information is defined as a master process and the remaining subscriber information is defined as a plurality of slave processes. It relates to a method of handling FA supplementary service calls at an exchange that controls all processes.

In general, supplementary services at exchanges are provided in addition to the basic services in the communication network to provide quality services to subscribers, and among these supplementary services, FA (Flexible Alerting) calls all subscribers in the group at the same time, giving the fastest response. The service is available for calling and the other subscribers are required to release the service.

In the conventional exchange, as shown in Fig. 1, the FA added service call processing apparatus is provided with a large number of exchanges 10 to N to provide FA added services for relay stations R2 and NO.

The first switch 10 includes a digital subscriber processing unit 11, a first number translation unit 12, an incoming call switching service processing unit 13, a routing processing unit 14, and a first UPC 15. It is done by

The second switch 20 includes a second digital subscriber processor 21, a second number translation unit 22, an incoming call switching service processor 23, a routing processor 24, and a second UPC 25. It is provided with.

The digital subscriber processing unit (11, 21) performs the incoming and outgoing processing of the digital subscriber and the state management of the subscriber, and controls the call request of the subscriber and the incoming call number and the call connection with the called subscriber.

The number translation unit 12, 22 performs international number, area code, and country number translation to process outgoing calls, incoming calls, translate incoming numbers to process the information of the called party, and translates special numbers to provide special services. Perform.

The FA additional service processing unit 13, 23 performs an incoming call role when receiving the incoming call transfer request from the digital subscriber processing units 11, 21 and is responsible for outgoing call processing for which the incoming call transfer is registered.

The UPCs 15 and 25 interoperate with the routing processing unit 14 to control and manage incoming and outgoing calls.

The routing processing unit 14, 24 receives the outgoing routing request signal transmitted from the number translation unit 12, 22, extracts the route of the other station in which the called party is mounted, and outgoes the outgoing route to the UPC 15, 25. Send the occupancy request.

Meanwhile, as shown in FIG. 2, the FA additional service units 13 and 23 include a subscriber control process block 13ab, a plurality of originating process blocks 13a-1 to 13a-n, and a plurality of called subscribers. Process blocks 13b-1 to 13b-n.

The subscriber control process block 13ab controls and manages the plurality of originating process blocks 13a-1 through 13a-n and the plurality of called subscriber process blocks 13b-1 through 13b-n.

The plurality of originating process blocks 13a-1 to 13a-n transmits subscriber information to each called subscriber process block 13b-1 to 13b-n according to the control of the subscriber control process block 13ab to establish a call. do.

The plurality of called subscriber process blocks 13b-1 to 13b-n are connected by receiving subscriber information from each originating process block 13a-1 to 13a-n.

As described above, in the conventional exchange, the FA additional service call processing process calls a specific called subscriber, and when the digital subscriber processor 11 in the first exchange sends the incoming translation request to the number translation unit 12, The number translation unit 12 is required to occupy the FA additional service subscribers after the incoming number translation.

Accordingly, the digital subscriber processing unit 11 checks the registration of the supplementary service according to the request for the occupancy of the FA supplementary service and calls the called party when the corresponding FA supplementary service is not a registered subscriber, and the call is connected. In the case of the subscriber who is registered with the FA value added service, the FA additional service processing unit 13 sends and receives as many N number of the corresponding FA value added members as requested by the FA value added service. 2N + 1 is needed to control the subscriber's process.

In this case, in the case of a plurality of originating processes to which call resources must be allocated, several processes that perform the same processing must be generated.

Thus, the corresponding subscriber control process block 13ab in the FA additional service processing unit 13 manages and controls the plurality of origination and reception process blocks 13a-1 to 13a-n and 13b-1 to 13b-n. The calling process blocks 13a-1 to 13a-n transmit the called subscriber information to each called subscriber process block 13b-1 to 13b-n according to the control of the corresponding subscriber control process block 13ab. In each called party process block 13b-1 to 13b-n, the call proceeds according to the called party information.

Accordingly, the number translation unit 13 translates the FA added service subscriber number and then makes outgoing routing requests, and the routing processing unit 14 extracts the route of the second exchanger 20 to update the outgoing occupancy request. ), And the UPC 15 transmits an IAM (Initial Address Message) message to the second exchange 20.

Accordingly, the IAM message applied by the UPC 25 in the second exchanger 20 is analyzed and then applied to the number translation unit 22 to request a translation of the called party number, and the corresponding number translation unit 22 receives the called party number. After translating and authorizing it to the digital subscriber processing unit 21, the FA is connected to the called subscriber according to the service occupancy request.

As described above, in the conventional exchange, when the FA supplementary service attempts to call the representative number of the FA group, it is possible to call all the subscribers in the group at the same time so that the call can be made with the fastest answering subscriber and the other subscribers request the release. The MSC must call several subscribers at the same time and be able to control them simultaneously.

Therefore, there is a problem in inefficient use of call resources because an arbitrary process that needs to control several calls simultaneously and a large number of incoming and outgoing subscriber processes as many as the called member number are required.

The present invention has been made in view of the above-described problems, and in the FA added service call processing at the exchange, the first called subscriber information is defined as the master process without any process requiring simultaneous control of several calls. By setting the subscriber's information as a slave process and proceeding with a call of a plurality of slave processes under the control of the corresponding master process, it is to simply process each repeated call setup to save call processing resources and efficiently provide process management.

In order to achieve the above object, the present invention comprises the steps of determining the information of the first subscriber of the various incoming information as a master processor; Determining the remaining subscriber information as a slave processor after determining the master processor; And performing a call of a plurality of slave processors under the control of the master processor.

On the other hand, the process of calling a specific called party from any originating subscriber, attempting to call, and checking whether the FA added service subscriber after the subscriber information inquiry; Transmitting the FA added service request signal and the called subscriber information to the FA added service processor in the case of the FA added service subscriber; Receiving, by the FA supplementary service processor, the receiving subscriber information according to the FA supplementary service request, and transmitting information of all FA members one by one in an originating process block in the corresponding FA supplementary service processing unit; Designating the first called subscriber information among the information of the FA member as a called master process block to store the called information, and designating a plurality of called slave process blocks as the remaining called subscriber information to store the called information; Receiving the respective incoming information from the plurality of incoming slave process blocks, applying the corresponding slave process ID and the slave number to the corresponding destination master process block, and continuing the call independently; The receiving master process block may also receive and store the corresponding slave process IDs and slave numbers from the plurality of incoming slave process blocks, and continue the call of the first called subscriber information.

On the other hand, when an error occurs during a call to the FA additional service processor, that is, when an error occurs in the corresponding destination master process block, the FA master replacement signal is transmitted to the first destination slave process block due to an error of the destination master process block. Requesting the master process to be replaced by itself and stopping the call from proceeding; Receiving a FA master replacement signal from the corresponding destination master process block 13b-1 in the first incoming slave process block to transmit an FA master response signal, and notifying the other incoming slave process blocks that they are master processes; ; And returning to the process of checking whether an error occurs during the call progress and continuing the call in the replaced incoming master process block, the second incoming slave process block, and the remaining incoming slave process block. do.

On the other hand, when the FA does not receive an error during the call processing to the service processing unit, when the first receiving the response from the incoming master process block, the process of recognizing that the call is first connected to the incoming master process block; Generating a FA release signal and applying the same to a plurality of destination slave process blocks to request FA release; Stopping the call progress by receiving a FA release signal from the terminating master process block in the plurality of terminating slave process blocks; The called master process block may include a process of call connection with the called subscriber.

Meanwhile, when receiving a response from the first incoming slave process block among the plurality of incoming slave process blocks during the call progress to the FA additional service processor, the first incoming slave process block recognizes that the call is connected first. And notifying the called master process block and the remaining called slave process blocks; Requesting FA release by first applying a FA release signal to the incoming master process block; Recognizing that a call is connected first in the first inbound slave process block in the inbound master process block, and applying a FA release signal to the remaining inbound slave process block; Stopping call progress in response to receiving the FA release signal from the remaining destination slave process block; And a call connection with the called subscriber in the first called slave process block.

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

The FA added service call processing apparatus according to the embodiment of the present invention, as shown in FIG. 1, includes a plurality of exchanges 10 to N, and the configuration blocks within the exchanges 10 to N are conventionally described. Since it is the same as that, the description is omitted.

Meanwhile, as shown in FIG. 3, the FA additional service processing units 13 and 23 may include an originating process block 13a, a terminating master process block 13-1, and a plurality of terminating slave process blocks ( 13-2 to 13-n).

The originating process block 13a sets up a call according to the subscriber information to determine the information of the first subscriber as the destination master process block 13-1, and the information of the remaining subscribers afterwards is called the slave slave process block 13-2 to 13-. n).

The terminating master process block 13-1 controls and manages the plurality of terminating slave process blocks 13-2 to 13-n, and calls and IDs of the corresponding terminating slave process blocks 13-2 to 13-n. It stores the information related to the control and sets up the call for each incoming slave process block 13-2 through 13-n.

The plurality of terminating slave process blocks 13-2 to 13-n are connected by a call under the control of the terminating master process block 13-1, and the master process is replaced when an error occurs in the corresponding terminating master processor block 13-1. Send and receive signals.

The operation of the present invention configured as described above will be described in detail with reference to FIG. 4 as follows.

First, when a particular called party is called by an arbitrary calling party, the digital subscriber processing unit 11 receives the called number dialed by the calling party and requests the number translation unit 12 to translate the number (step S1).

Accordingly, the number translation unit 12 translates the called party number and requests the occupant subscriber to the digital subscriber processing unit 11 (step S2), and the digital subscriber processing unit 11 determines whether it is a FA added service subscriber. It checks whether or not (step S3), the called party is called in the case of a normal call, and if the FA added service is a subscriber, the FA added service request signal and the called subscriber information are transmitted to the FA added service processor 13 ( Step S4, S5).

Accordingly, the FA additional service processing unit 13 receives the FA additional service request signal and the incoming subscriber information from the digital subscriber processing unit 11, and the FA member in the originating process block 31a in the FA additional service processing unit 13 is received. All information is transmitted one by one (step S5).

Then, the first called subscriber information among the information of the corresponding FA member is designated as the called master process block 13-1 to store the called information, and the standby state is set for the remaining subscriber information (step S6).

Then, when the FA adds the remaining called subscriber information in the originating process block 13-1 in the service processing unit 13, the called subscriber information is authorized to receive a plurality of called slave process blocks 13-2 through 13-n. And the destination information is stored (step S7).

Accordingly, a plurality of destination slave process blocks 13-2 to 13-n receive respective incoming information and apply the corresponding slave process ID and slave number to the corresponding destination master process block 13b-1, and apply their own calls. The process proceeds independently (step S8).

In addition, the called master process block 13-1 receives and stores the corresponding slave process ID and the slave number from the plurality of called slave process blocks 13-2 to 13-n, and stores the first called subscriber information with respect to the first called subscriber information. The arc of (1) is continued (step S9).

In this case, when an error occurs during the call progress for the FA additional service, that is, when an error occurs in the corresponding destination master process block 13-1, the error is caused by the corresponding destination master process block 13-1. The FA master replacement signal is applied to the first incoming slave process block 13-2 to request the master process to be replaced, and it stops the call progress (steps S10 and S11).

Accordingly, the first incoming slave process block 13-2 receives the FA master replacement signal from the corresponding incoming master process block 13-1, transmits the FA master response signal, and the remaining incoming slave process blocks 13-3 ~. 13-n), it informs itself that it is a master process (step S12).

Accordingly, the incoming call master process block 13-2, the second incoming slave process block 13-3, and the remaining incoming slave process blocks 13-4 to 13-n continue to proceed with the call. It returns to 10 steps (step S13).

On the other hand, when an error does not occur during the call progress for the FA additional service and a response is first received in the called master process block 13-1, the called master is first connected to the called master process block 13-1. (Steps S14 and S15), FA release signals are generated and applied to a plurality of destination slave process blocks 13-2 to 13-n to request FA release (step S16).

Then, the plurality of destination slave process blocks 13-2 to 13-n receive the FA release signal from the destination master process block 13-1 to stop the call progress (step S17).

Accordingly, the called master process block 13-1 is connected to the called subscriber (step S18).

Meanwhile, assuming that the first incoming slave process block 13-2 first receives a response from among a plurality of incoming slave process blocks while the FA additional service is in progress, the first incoming slave process block ( 13-2) first recognizes that the call is connected, and informs the destination master process block (13-1) and the remaining destination slave process blocks (13-2 ~ 13-n).

Then, the FA release signal is first applied to the destination master process block 13-1 to request FA release (steps S19 and S20), and the destination master process block 13-1 requests the first destination slave process block. In step 13-2, the call is known to be connected first, and the FA release signal is applied to the remaining destination slave process blocks 13-3 to 13-n, and then the call progress is stopped (step S21).

Thereafter, the remaining call slave process blocks 13-3 to 13-n also stop the call progress in response to receiving the FA release signal (step S22).

Accordingly, the first destination slave process block 13-2 is connected to the call subscriber (step S23).

As described above, in the FA additional service call processing in the exchange of the present invention, the first subscriber information among the various incoming information is defined as the master process in the originating process, without any process having to control several calls simultaneously. By reducing the subscriber's information as a slave process to reduce unnecessary outgoing processes and proceeding with a call of multiple slave processes under the control of the incoming master process, it simply processes each repeated call setup and saves resources by effectively reducing call processing procedures. The service function can be enabled.

As described above, in the present invention, in the FA added service call processing, the first destination subscriber information is designated as the master process, and the remaining subscriber information is transferred to the slave process without any process requiring simultaneous control of several calls. By selecting and proceeding with a call of a plurality of slave processes according to the control of the corresponding master process, it is possible to simply process each repeated call setting, saving call processing resources and efficient process management.
