Announcement broadcasting method and system {METHOD FOR TRANSMITTING ANNOUNCEMENT FOR SUBSCRIBERS AND SYSTEM THEREOF}

The present invention relates to an announcement broadcast transmission. In detail, when the reception of a call fails in a mobile communication system, the announcement of the failure of the call is transmitted in the national language of the call originator to convey the cause of the failure of the announcement to the caller. The present invention relates to a method and a system for transmitting announcement broadcasts that can reduce the cost burden that can be generated unnecessarily.

The mobile communication network is responsible for the cause of unsuccessful call when the call originated by the caller fails due to the inaccessible status of the called subscriber, the inability to receive by additional service provided by the mobile communication network, the missing number of the called number, the congestion of call volume and the network failure. The announcement is sent to the caller.

Here, the announcement broadcast transmitted by the mobile communication network to the caller is transmitted only in the language of the country where the mobile communication network is located and the preset national language. For example, in Korea, a mobile communication network transmits a guide broadcast on a cause of a call failure in Korean and English.

However, a caller who does not know the country language being sent because the announcement is broadcast only in a specific language for the cause of the call failure in the mobile communication network, for example, an overseas network subscriber and an inbound roaming in the home network that provides the mobile communication service Roamer and others do not know the cause of the incoming failure. Therefore, the caller of the overseas network subscriber and the inbound roamer, etc. do not know the cause of the incoming failure to continue trying to occupy the unnecessary ISUP line, there is a problem that causes various costs.

An object of the present invention was devised to solve the above-mentioned problems, by transmitting the announcement in the national language of the caller using the country code of the caller who originated the call when it is necessary to send the announcement for the received call, The present invention provides a method and system for transmitting an announcement broadcast that can accurately provide the cause of an incoming call failure to an overseas network subscriber.

Another object of the present invention is to provide a guide broadcast transmission method and system that can reduce the cost of the caller by suppressing unnecessary call transmission by sending a guide broadcast on the cause of the incoming call to the overseas network subscribers in the national language of the caller To provide.

In order to achieve the above object, the announcement broadcast transmission method according to an aspect of the present invention comprises the steps of: determining whether an originating number included in the call is an international call type when an announcement broadcast code for a call is received; Retrieving a caller's country code based on the calling number if the calling number is an international call type; Searching for a country code announcement broadcast code corresponding to the announcement code and the searched country code among country code announcement broadcast codes preset for each country; And transmitting a guide broadcast for the call corresponding to the country code announcement broadcast code searched in a national language corresponding to the searched country code.

The announcement broadcasting system according to an aspect of the present invention receives information about a call, retrieves the announcement broadcast code when the announcement is necessary for the call, and determines whether the calling number included in the call is an international call type. In the case of an international call type, the country code of the caller is searched based on the calling number, and the country code announcement broadcast code corresponding to the announcement code and the searched country code is searched among the country code announcement broadcast codes set by country. Transmitting HLR; And receiving the call, transmitting information about the call to the HLR, receiving the country code announcement broadcast code from the HLR, and corresponding to the country code announcement broadcast code retrieved in a national language corresponding to the country code retrieved. And an MSC for transmitting the announcement broadcast for the call.

According to another aspect of the present invention, an announcement broadcasting system includes: an HLR for receiving information on a call and searching for and transmitting a corresponding announcement code when an announcement broadcast for the call is required; And receiving the call, transmitting information on the call to the HLR, receiving the announcement broadcast code from the HLR, determining whether the caller ID included in the call is an international call type, and calling the caller ID if the call is an international call type. Searching the caller's country code based on the country, and search for the announcement code and the country code announcement code corresponding to the searched country code of the country code announcement code set by country to the country language corresponding to the searched country code And an MSC for transmitting the announcement broadcast for the call corresponding to the retrieved country code announcement broadcast code.

According to the present invention, when an announcement is required for a received call, the announcement is transmitted in a country language of the caller by using the country code of the originator who originated the call, thereby accurately identifying the cause of the failure of the incoming call to the overseas network subscriber. There is an effect that can be provided.

In addition, the present invention has the effect of reducing the caller's cost by suppressing unnecessary call origination by sending a guide broadcast on the cause of the incoming call to the overseas network subscribers in the national language of the caller.

Other objects and features of the present invention in addition to the above object will be apparent from the description of the embodiments with reference to the accompanying drawings.

Hereinafter, a method and system for transmitting announcement broadcasts according to an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 5.

The present invention describes a case where an overseas network subscriber sends a call from a foreign network to a home network subscriber or an overseas network subscriber sends a call from a home network to a home network subscriber.

In addition, the announcement broadcast code used in the present invention includes an error code.

1 is a block diagram of a guide broadcast transmission system according to an embodiment of the present invention.

Referring to FIG. 1, the announcement broadcast transmission system includes an MSC 120 and an HLR 130 configured in a home network.

Here, the announcement broadcast transmission system will be described in three cases, but the destination terminal will be described limited to the home network subscriber station.

1) The case in which the HLR 130 searches for and provides a guide broadcast code necessary for transmitting a broadcast announcement, and the MSC 120 searches for a caller's country code (CC) to transmit the guide broadcast in the caller's national language. Is as follows.

The MSC 120 receives a call originating from an overseas network subscriber terminal 140 located in an overseas network through the overseas network MSC 110 or a call originating from an overseas network subscriber terminal 150 located in a home network. Information about the call, for example, SRI (Send Routing Info.) Message requesting the routing information (MSRN) of the destination MSC to the HLR (130), SRI ACK message containing an announcement broadcast code from the HLR (130) It receives and transmits the announcement of the failure of the call to the home network subscriber terminal in the national language of the caller, that is, the overseas network subscriber.

At this time, when the MSC 120 receives the announcement code from the HLR 130, the MSC 120 determines whether the received call number is an international call type. National announcement code), and search for a country announcement code corresponding to the caller's country code among the converted country announcement codes, and transmit a announcement corresponding to the retrieved country announcement code in the sender's country language. . That is, in order to transmit the announcement in a national language in the present invention, it is preferable that the announcement broadcast code and announcement broadcasts corresponding to the country code are stored in advance, and the country code is preferably managed in the station data.

Here, the MSC 120 may retrieve the caller's country code based on the calling number included in the call, and retrieve the caller's country code based on the calling party IMSI or calling number stored in the VLR (Visited Location Register). The country code is retrieved based on the caller IMSI or caller number stored in the VLR when the caller is an overseas network subscriber and inbound roams to the home network. That is, when the MSC 120 receives a call from the home network and receives a guide broadcast code for transmitting an announcement from the HLR 130, the MSC 120 determines whether the caller is a home network subscriber and is a foreign subscriber instead of a home network subscriber. Search for the country code of the caller based on the caller IMSI or caller number stored in the station and send the announcement in the caller's country language.

When a call originates from an overseas network subscriber, the MSC 120 may retrieve the caller's country code from the country code included in the caller's number because the country code is included in the caller's number.

The HLR 130 receives the SRI message from the MSC 120, and if an incoming call to the called subscriber is failed based on the called number included in the SRI message, an announcement broadcast code for the cause of the failed call is provided. The SRI ACK message including the found announcement code is transmitted to the MSC 120.

2) HLR (130) to search the country code of the caller to search and provide a country announcement code corresponding to the country code of the caller necessary for announcement broadcast transmission, MSC (120) country announcement broadcast code in the country language of the caller A case of transmitting a guide broadcast corresponding to the following will be described.

For example, the MSC 120 transmits an SRI message to the HLR 130 when the call is received. When the MSC 120 receives a country announcement code corresponding to the caller's country code from the HLR 130, the MSC 120 receives the caller's country. The announcement broadcasts corresponding to the national announcement code in a language.

The HLR 130 receives the SRI message, and if it is necessary to send the announcement broadcast, determines whether the caller's calling number is an international call type, and if the call is an international call type, the national announcement broadcast corresponding to the calling country code through the country code included in the calling number. The code is retrieved and an SRI ACK message containing the retrieved national announcement code is transmitted to the MSC 120. That is, in case of 1), the HLR 130 performs a search function for the country code search function of the caller and the country guide broadcast code corresponding to the caller's country code, which was performed by the MSC 120.

3) The MSC 120 searches for an announcement broadcast code and a caller's country code required for announcement broadcast transmission, and describes a case in which announcement broadcast is transmitted in a caller's national language as follows.

This may be the case when a call is unsuccessful due to a surge of call volume or when the called number is missing.

That is, when the call is received and the announcement broadcast for the received call is required, the MSC 120 determines whether the caller ID is the international call type and searches the country code included in the caller ID when the call is an international call type.

The MSC 120 retrieves the national announcement code corresponding to the retrieved country code and sends out the announcement corresponding to the retrieved national announcement code in the sender's national language.

As described above, the announcement broadcast transmission system according to the present invention searches for a country announcement broadcast code corresponding to the caller's country code, and transmits the announcement broadcast corresponding to the searched country announcement broadcast code in the caller's country language. Can provide the exact cause of the incoming call failure.

2 is a flowchart illustrating an announcement broadcast transmission process according to an embodiment of the present invention.

Referring to FIG. 2, when an overseas network subscriber station (MS) located in an overseas network sends a call to a home network subscription terminal, the overseas network MSC receives the call and sends an IAM (Initial Address) to the MSC of the home network through the international telephone service provider section. Message) Send a message (S210, S220).

The MSC of the home network receives the IAM message and transmits an SRI message to the HLR (S230).

Here, the SRI message includes a calling number and a called number. The calling number becomes a Mobile Subscriber Integrated Service Digital Network (MSISDN) of an overseas network subscriber MS, and the called number becomes an MSISDN of a home network subscriber MS.

At this time, the calling number includes a country code.

The HLR receives the SRI message and determines whether the announcement is necessary based on the called number included in the SRI message. When the announcement is required, the HLR is based on the calling number included in the SRI message. It is determined whether to include (S240, S250).

That is, the HLR needs to send an announcement broadcast when the called terminal cannot receive a call, for example, when the called terminal is powered off, and the calling number is sent to send the announcement in the caller's national language. Determine if the international call type includes country code.

As a result of the determination in step S250, if the calling number includes the country code, the HLR searches for the country code of the caller, and searches for a country announcement broadcast code for the found country code of the calling party (S260).

Here, it is preferable that the HLR searches the national announcement broadcast code based on the broadcast announcement code and the caller's country code.

The HLR transmits an SRI ACK message including the found country announcement code to the MSC of the home network when the announcement code for the caller's country code, that is, the country announcement code, is searched (S270).

The MSC of the home network detects the national announcement broadcast code included in the SRI ACK message, and transmits the announcement corresponding to the national announcement broadcast code to the overseas network subscriber MS that has sent the call (S280). That is, the MSC of the home network transmits a guide broadcast on the cause of the call failure in the national language of the overseas network subscriber who is the call originator.

3 is a flowchart illustrating an announcement broadcast transmission process according to another embodiment of the present invention.

Referring to FIG. 3, when an overseas network subscription MS located in an overseas network sends a call to a home network subscription terminal, the overseas network MSC receives the call and transmits an IAM message to the MSC of the home network through an international telephone operator section (S310). , S320).

The MSC of the home network receives the IAM message and transmits an SRI message to the HLR (S330).

The HLR receives the SRI message, determines whether the announcement broadcast is necessary based on the SRI message, and searches for the announcement broadcast code to be transmitted when the announcement broadcast is necessary (S340 and S350).

If the announcement code is found, the HLR transmits an SRI ACK message including the found announcement code to the MSC of the home network (S360).

When the MSC of the home network receives the SRI ACK message including the announcement broadcast code, the MSC determines whether the calling number for the call received from the MSC of the overseas network is an international call type including a country code (S370).

As a result of the determination in step S370, if the calling number includes the country code, the MSC of the home network converts the announcement broadcast code received from the HLR into a country announcement broadcast code for each country code (S380). For example, the MSC of the home network may output a guide broadcast code capable of outputting the announcement of the cause of a call failure in the national language of the home network received from the HLR in a country language corresponding to each of the country codes. Convert to announcement code.

The MSC of the home network searches the country announcement code corresponding to the caller's country code among the country announcement codes converted based on the country code included in the calling number, and sends the announcement corresponding to the retrieved country announcement code. Send in the national language (S390). Of course, the announcement corresponding to the country announcement code is obviously recorded in the sender's national language.

FIG. 4 is a flowchart illustrating a process of transmitting an announcement broadcast according to another embodiment of the present invention, and an operation of transmitting an announcement broadcast in a caller's national language when an announcement broadcast is required in an MSC of a home network. It is a flow chart.

Referring to FIG. 4, when an overseas network subscriber located in an overseas network sends a call to a home network subscriber, that is, when the overseas network subscriber MS sends a call to the home network subscriber MS, the MSC of the overseas network receives the call and receives the call. The IAM message is transmitted to the MSC (S410 and S420).

The MSC of the home network determines that an announcement broadcast is necessary if a call is unsuccessful due to a congestion of calls and a missing number, and the calling number is based on the calling number included in the call to send the announcement. It is determined whether the type and the country code (S430, S440).

In step S440, if the call number is an international call type including a country code, the MSC of the home network searches for a country announcement code corresponding to the caller's country code, and transmits an announcement corresponding to the retrieved country announcement code. Transmission in the national language (S450, S460).

FIG. 5 is a flowchart illustrating a process of transmitting an announcement broadcast according to another embodiment of the present invention, in which an overseas network subscriber who is inbound roaming to a home network sends a call to a home network subscriber. to be.

Referring to FIG. 5, when an overseas network subscription MS inbound roaming to the home network sends a call to the home network subscription MS, the MSC of the home network receives the call and transmits an SRI message including the calling number and the called number to the HLR. (S510, S520).

The HLR receives the SRI message, determines whether the announcement broadcast is necessary based on the SRI message, and searches for the announcement broadcast code to be transmitted when the announcement broadcast is necessary (S530 and S340).

If the announcement code is found, the HLR transmits an SRI ACK message including the found announcement code to the MSC of the home network (S550).

When the MSC of the home network receives an SRI ACK message including an announcement broadcast code, the MSC determines whether the caller is a home network subscriber (S560). That is, the MSC of the home network determines whether the originator of the call is a home network subscriber or an overseas network subscriber.

In step S560, if the caller is an overseas subscriber, the MSC of the home network retrieves the caller's country code based on the mobile country code (MCC) / mobile network code (MNC) or the calling number included in the IMSI of the caller stored in the VLR. (S570).

The MSC of the home network searches for a country announcement code corresponding to the retrieved caller's country code and the announcement code received from the HLR, and transmits the retrieved country announcement code in the sender's country language (S580).

At this time, the MSC of the home network converts the announcement broadcast code received from the HLR into a country announcement broadcast code for each country code if the caller is determined to be an overseas subscriber, and then searches for a country announcement broadcast code corresponding to the retrieved country code. The country announcement code may also be transmitted in the sender's country language.

Of course, if the MSC of the home network receives a call from an MS registered in an overseas network located in the home network, and the received call fails to be received due to a congestion of call volume and a missing number, it is determined that the caller is an overseas network subscriber. In the case of the subscriber, by performing the steps S570 and S580 shown in FIG. 5, the announcement may be transmitted to the caller in the caller's national language.

Also, although not shown, when the MSC of the home network receives a call sent by an overseas network subscriber MS located in the home network, an SRI message is transmitted to the HLR, and when the HLR needs to send a broadcast announcement for the call, the caller's country code By searching for and transmitting a country announcement code corresponding to the caller's country code to the MSC of the home network, the MSC of the home network may transmit a announcement corresponding to the country announcement code in the sender's country language.

As can be seen from the above-described Figures 2 to 5, the guide broadcast transmission method according to the present invention, if a call originating from an overseas network subscription MS located in an overseas network or an overseas network subscription MS inbound roaming to a home network fails to receive, Since the announcement of the cause of failure is sent in the caller's national language, the caller can be accurately provided the cause of the call failure.

The announcement broadcast transmission method and the system according to the present invention can be variously modified and applied within the scope of the technical idea of the present invention and are not limited to the above embodiments. In addition, the embodiments and drawings are merely for the purpose of describing the contents of the invention in detail, not intended to limit the scope of the technical idea of the invention, the present invention described above is common knowledge in the technical field to which the present invention belongs As those skilled in the art can have various substitutions, modifications, and changes without departing from the spirit of the present invention, it is not limited to the embodiments and the accompanying drawings.
