Description

Guidance broadcasting providing system of the switching system and guidance broadcasting providing method using the same

The present invention relates to a guide broadcasting providing system of a switching system and a guide broadcasting providing method using the same, and more particularly, to a guide broadcasting providing system and a guide broadcasting providing method of a switching system suitable for providing guide broadcasting to a large number of subscribers in the switching system. .

In order to provide announcements to many subscribers in the switching system, additional generation of announcement equipment was required according to the required capacity. Particularly, in the mobile network, there are frequent requests for announcements such as unknown location, power down, transfer, busy, no paging response, and no answer depending on the radio environment or subscriber characteristics. At the same time, a large amount of announcements were required.

In the following, a general exchange system will be described.

1 is a basic block diagram of a general exchange system.

As shown in FIG. 1, the basic configuration of the switching system is a global switching subsystem (SS_G) for responding to call processing requests for fixed subscribers, trunks, announcements, conference call subscribers, and the like. (1) and a Mobile Switching Subsystem (SS_M) for responding to call processing requests of mobile subscribers, such as cellular and personal mobile communication (SSS), and for switching between exchanges. Trunk Switching Subsystem (SS_T) (3) and various signal relay switching subsystems (SS_7) which are number 7 (signal relay switches) for relaying control and messages of basic call signals and intelligent network service signals. No. 7 switching subsystem (4), the global switching subsystem (1), mobile subscriber switching subsystem (2), relay line matching switching subsystem (3) and various signal switching sub It is composed of: (Switching Time, Space Switching TSW, SSW) (5), the stem (4) the time and the time for spatial matched and space switching unit.

This time and space switching section 5 connects the switching subsystems between different switching stations.

At this time, the time switching unit TSW time-divisions the communication between the switching subsystems 1, 2, 3, and 4 to randomly respond to the call processing request regardless of the call processing request inputted first. To respond.

One global switching subsystem 1 operates a 2K 2048 communication channel. Also, about 100 channels besides channels for subscribers and trunk calls among 2K (2048) channels are used as guide broadcast channels for informing subscribers of call processing failure when call processing fails.

2 is a block diagram of a global switching subsystem of a conventional switching system.

As shown in FIG. 2, the basic configuration of the global switching subsystem includes redundant first and second control boards 6a and 6b, and an auxiliary processor 7 for controlling the control boards 6a and 6b. The main processor 8 controls the coprocessor 7.

In this case, the coprocessor 7 may be a coprocessor for managing a fixed subscriber, a coprocessor for controlling communication with subscribers in other regions via a relay line, a coprocessor for controlling communication with a mobile terminal (mobile phone), and announcement broadcasting. There are a plurality of coprocessors, such as a coprocessor for controlling the information broadcast device control unit (which belongs to the control board 6) to provide, the main processor 8 controls a plurality of coprocessors as described above.

Each of the coprocessors 7 controls the control board 6 for performing various tasks (fixed subscriber management, communication with subscribers in other areas through a relay line, and control of announcement broadcasting devices). .

3 is a block diagram of a conventional announcement control block.

That is, in the conventional guide broadcasting control, as shown in FIG. 3, the guide broadcasting device control unit 9 which provides guide broadcasting for the call processing failure caused by various causes in the call processing request, and the guide broadcasting device control unit 9 Time Switching Unit (TSW), which is connected to a sub highway cable (SHW) and matches a channel for connecting announcements to call processing requests received through each subsystem (SS-G) (SS_T) (SS_M). : Controls the announcement by using the switch connection control unit 10 consisting of: Time Switching) and space switching (SSW).

At this time, the announcement device control unit 9 is configured in the global switching subsystem SS_G, and about 32 announcement message source units 11 (the number of announcement messages differs depending on the announcement device). And a plurality (for example, 128) of transmission channel units 12, and belong to one control board (No. 6 in FIG. 2).

In addition, the switch connection control unit 10 is provided in the national and mobile switchboards, and includes a plurality of (for example, 128) reception channel units 13 and a space switching unit (regardless of an input time point). SSW) is located between the first time switching unit 14 and the time switching unit 14, 16 for connecting to the call processing subscribers of various states (mobile phone users, local telephone users) A second time switching unit for inputting, through the reception channel unit 13, the guidance broadcast received through the spatial switching unit 15 and the spatial switching unit 15 to each of the subsystems SS_M, SS_G, and SS_T. It consists of (16).

A guide broadcast control block as described above will be described.

First, when call processing is performed using a communication system, it is passed through the switching center. At this time, various causes of call processing of subscribers of various switching subsystems (SS_M) (SS_G) (SS_T) of the same switching center or different switching stations (different regions) are unidentified, power down, transfer, busy, paging failure, and no response. If the call processing fails, the announcement device control unit 9 provided in the global switching subsystem SS_G in the switching center automatically provides the call processing requester with a guide message for the call processing failure.

At this time, generally, 128 channels (depending on the device, generally about 100) of 2K channels included in one global switching subsystem SS_G are dedicated to the announcement broadcasting channel, and various switching subsystems SS_M are used. When the call processing fails due to various causes in the call processing occurring in (SS_G) (SS_T), the announcement broadcast is provided for each call processing failure in 128 guide dedicated channels. That is, one channel of the dedicated announcement channel is provided for one call processing failure occurring through one channel.

Referring to FIG. 3 again, if the call processing requester fails to process the call, the cause of the message 2 of the messages of the announcement message source unit 11 belonging to the announcement device control unit 9 is the cause thereof. In this case, first, one of the channels of the transmission channel unit 12 to provide the announcement broadcast to the announcement broadcasting device control unit 9 should be provided.

In this case, channel 3 is allocated for convenience.

Subsequently, when the second announcement message of the announcement message source unit 11 is provided to the third channel of the transmission channel unit 12, the third channel of the transmission channel unit 12 is switched through the cable SHW. The announcement broadcast message is transmitted to channel 3 of the reception channel unit 14 of (10).

The channel 3 of the receiving channel section 14 then transmits its contents to the first time switching section 14 and continues to the call processing requester via the spatial switching section 15 and the second time switching section 14. Deliver announcement message.

However, the conventional guide broadcasting control method has the following problems.

Since the number of dedicated broadcast channels provided to each subscriber in the broadcast equipment is limited (around 100), when a call processing failure increases rapidly, the broadcast message cannot be provided by the controller of the broadcast device controller. The call processing requester is either waited or replaced with a tone signal until the call is terminated.

However, the method of waiting for the call processing requester until the current announcement message is terminated has caused other call processing failures because the subscriber's dissatisfaction due to the delay in the announcement broadcast and the channel necessary for the actual call processing are unnecessarily occupied. .

In addition, the method of replacing with a beeper is fast in responding to the failure of the call processing, but does not provide the cause of the failure of the call processing, so it cannot be clearly handled (especially power down). Problems such as call processing

The present invention is to solve the problems of the conventional guide broadcasting providing system and the guide broadcasting providing method using the same. When the subscriber fails to handle the call in the switching system, the call processing fails due to the same cause among various call processing failure requesters. The announcement broadcasting system of the exchange system that can collect subscribers and provide announcements simultaneously to the aggregated subscribers to promptly identify the cause of the call processing failure, thereby eliminating the subscriber's complaints and improving the subscriber's reliability. The purpose is to provide a method of providing announcements.

The guidance broadcasting providing system of the present invention switching system for achieving the above object is a guide broadcasting which provides various appropriate announcements to the subscriber when the call processing fails with the other party when the wired and mobile subscriber requests the call processing. A switching system comprising a device control unit and a switch connection control unit comprising a time and space switching unit for matching a channel for providing an announcement to a call processing request, wherein the switch system includes a plurality of devices for a predetermined time when a call processing request requiring announcement is generated. And a guide broadcast connection control unit for collecting call processing request signals requiring the same contents of the same announcement message and transmitting the same to the announcement device control unit. In addition, the above-described method for providing announcement service of a switching system includes a process of requesting to connect a subscriber announcement to a subscriber belonging to a plurality of switching subsystems in the exchange system, and periodically requesting the announcement announcement connection request from the announcement broadcast control unit. Performing a search, determining whether there is a call processing failure requestor requesting the same announcement message as a result of the search, collecting subscriber signals requesting the same announcement broadcast, and requesting the announcement announcement message.

The guide broadcast control system according to the present invention, as shown in 4, a guide broadcast device control unit 21 for providing a guide broadcast for the call processing failure caused by various causes when the call processing request, and the guide broadcast device control unit Time to match the channel to provide the guidance broadcast for the call processing request through each sub-system (SS-G) (SS_T) (SS_M) connected to the cable (SHW: Sub Highway Cable) A switch connection control unit 22 comprising a switching unit TSW and a spatial switching unit and a call processing requester requiring a plurality of identical announcement message requests for a predetermined time when a call processing request requiring announcement is generated. And a guide broadcast connection control unit 23 for collecting the broadcast information to the guide broadcast device control unit 21.

In this case, the announcement device control unit 21 is configured in the global switching subsystem SS_G, and includes about 32 announcement message source units 24 and a plurality of transmission channels (for example, 128). The part 25 is provided.

In addition, the switch connection control unit 22 is provided in the national and mobile switchboards, and includes a plurality of (for example, 128) reception channel units 26 and a spatial switching unit (regardless of an input time point). SSW (28) is connected between the first time switching unit 27 and the time switching unit 27, 29 to connect the call processor of various states (mobile phone users, local telephone users) appropriately The second time switching for inputting the guidance broadcasts received through the reception channel section 26 to each of the subsystems SS_M, SS_G, and SS_T in accordance with the connection of the spatial switching section 28 and the spatial switching section 28. It is composed of a portion 28.

At this time, the time switching unit 27, 29 has a time-sharing configuration irrespective of the order of call processing requesters, and the space switching unit 28 guides broadcasts to each of the subsystems SS_M, SS_G, and SS_T. Connect the channel.

And, the announcement broadcast control unit 23 is configured in the main processor of the global switching subsystem (SS_G), the same for the time that the subscriber requests the call processing, but the subscriber does not feel inconvenience when the call processing failure caused by various causes Call processing failures are collected and transmitted to the transmission channel section 25 of the announcement device control section 21.

At this time, if a cause of a call processing failure occurs after the call processing request, the main processor analyzes the cause of the call processing failure at a predetermined time period and aggregates subscribers to transmit an appropriate announcement message. It then transmits to the transmission channel section 25.

That is, in the announcement message of FIG. 4, when the cause of failure of proper call processing occurs in the 32 announcement messages, 32 announcement messages are classified and aggregated in time division for 1 to 2 seconds.

At this time, the cause of failure of call processing suitable for announcement message 0 did not occur at the first set time, but two cause of failure of call processing for announcement message 1 occurred and call processing failed for announcement message 2 There are five causes and five cause of failure of call processing suitable for announcement message 3, and it can be seen that no cause of failure of call processing suitable for announcement message 4 occurs. Also, in the second set time of call processing failure, the cause of failure of call processing suitable for announcement message 0 did not occur. The cause of failure was also three, and two cause of failure of call processing suitable for announcement message 3 occurred, and the cause of failure of call processing suitable for announcement message 4 did not occur. The transmission channel section 25 of the announcement device control unit 21 is made by time-division gathering the announcements suitable for these 32 call processing failure causes (for example, call processing failure causes suitable for the announcement message # 2). And one channel (for example, channel 3) is allocated, and also connects the call path of the announcement message of announcement 2 of the announcement device control unit 21, and then switches the connection control unit 22 through the cable SHW. When sending to the receiving channel section 26, the switch connection control section 22 transmits the failure details to the switching subsystem SS_M (SS_G) (SS_T) of the call processing requesters.

When wired and mobile subscribers request call processing to the counterpart who wants to access through various switching subsystems of local and mobile switching system, if the call processing request with the other party fails for various reasons, the subscriber broadcasts appropriate to various reasons. A method for providing announcement of an exchange system having an announcement device control unit and an announcement broadcast connection control unit for generating and connecting a subscriber station, the subscriber who fails to process a call among subscribers belonging to a plurality of switching subsystems in the exchange system connects the announcement broadcast. It is required (S1).

The subscriber signal requesting to connect the announcement broadcasts is introduced into the announcement broadcast connection control section by time division, and the announcement broadcast connection control section performs a periodic search for aggregating subscriber signals requesting the same announcement broadcast of various causes. (S2). At this time, the search period is a time difference (preferably 1 to 2 seconds) that the subscriber does not feel uncomfortable.

According to the search result (S2), it is determined whether there are signals requesting the same announcement message, and at the same time, the same announcement message request signal is collected (S3).

According to the determination and the aggregation result, a channel of the announcement broadcasting device control unit is allocated to each of the aggregation announcement message request signals to which the same announcement message is to be provided (S4).

Next, it is determined whether the channel is properly allocated (S5).

At this time, if a channel is not allocated, a failure notification is sent to all subscriber-side switching subsystems in the unassigned set. In this case, since all the dedicated broadcast channels of the information broadcast device control unit are busy, a tone signal is provided to each subscriber.

If the channel is allocated according to the determination result (S5), and establishes a call path between the switching subsystem to which the corresponding announcement connection request subscriber belongs and the announcement broadcast control unit. That is, the guidance broadcast connection control unit is connected to various switching subsystems SS_G (SS_T) (SS_M) through a time and space switching unit (S6).

Then, it is determined whether the channel is allocated and the call path is properly connected (S8).

According to the determination result (S8), the subscriber is required to transmit the appropriate message to the channel of the announcement message of the announcement device control unit for the subscriber connected properly (S9).

Then, the service is individually terminated for the subscriber S10 which is not properly connected to the switching subsystem of the subscriber.

It is determined whether the requested announcement message is sent (S11).

If the guide broadcast is transmitted according to the determination result (S11), each of the same guide broadcast request subscriber receives the guide broadcast (S12).

However, if the announcement fails to transmit all the subscribers (S13) of the set failure notification is sent.

Then, when the announcement broadcast is completely terminated for the subscriber confirming the announcement message until the latest, the release procedure for closing the channel of the corresponding channel subscriber is performed (S14). At this time, even if all the subscribers are canceled reception in the state in which the announcement contents are not finished, the communication channel is closed to give the announcement dedicated channel.

In the guidance broadcasting providing system of the switching system and the guidance broadcasting providing method using the same according to the present invention, a call processing signal requesting the same announcement message is aggregated, and then a call path is established in the switching subsystem and then transmitted. The problem caused by lack of information broadcasting channel is solved to eliminate the dissatisfaction of subscribers of the exchange system and improve the reliability.
