Abstract

PURPOSE: A method for processing a multiple VMS(Voice Mailing Service) system in a mobile communication switching system is provided to make a VMS call be called in each ASS-V/F(Access Switching Subsystem-Voice/Fax Mail) by designating the corresponding ASS-V/F in each different VMS number for processing many VMS systems when a VMS system is extended according as a capacity to be processed by the VMS is increased by increasing a mobile telephone subscriber. CONSTITUTION: An ASS-V/F is classified and registered for classifying a plurality of VMS systems when a VMS number is created(S111). A call is attempted through a VMS number having a pre-registered calling block(S113). A number translation block judges whether the call is a VMS call and whether a pre-registered VMS number is called to a certain VMS system and informs the decision to a calling block(S115). The calling block transmits a signal for requesting an occupation of a VMS resource, and makes the VMS call be called to the corresponding ASS-V/F(S117).

Description

Method for processing multi-VMS system in MSC at mobile communication system

The present invention relates to a processing method of a multiple VMS (Voice Mailing Service) system, by specifying an ASS (Access Switching Subsystem) according to a VMS number to process a plurality of VMS systems, The present invention relates to a method for processing multiple VMS systems in a mobile communication switch that allows a voicemail request to be sent to a VMS system in a corresponding ASS.

In general, VMS (Voice Mailing Service) is a voice that allows the other party to listen to the terminal by recording a message when the calling subscriber can not talk to the other party in real time, such as when the other party is turned off or busy Mailbox service, which is provided by the Access Switching Subsystem (ASS) in the exchange.

1 is a block diagram schematically showing an internal configuration of an exchange in a general mobile communication system.

As shown, ASS (Access Switching Subsystem) 2, which performs most call processing functions except for number translation and call routing, is located at the center of the exchange and the ASS (2) is mutually or ASS (2). 9) Interconnection Network Subsystem (INS) (8), which includes a Number Translation Processor (NTP), and Central Control, which performs the overall operational management and maintenance of the exchange. Subsystem 9).

In addition, the ASS (2) performs the mobile call processing in the exchange (1), and the ASS-M (Access Switching Subsystem-Mobile) (3) that manages the incoming or outgoing processing of all mobile subscribers in the exchange, and the exchange ASS-T (Access Switching Subsystem-Trunks) (4) for performing mobile call processing of incoming and outgoing broadcasts, and Access Switching Subsystme-Subscriber lines (5) for connection with fixed subscribers, And ASS-7 (Access Switching Subsystem-No.7) (6) which performs number 7 function and ASS-V / F (Access Switching Subsystem-Voice / Fax Mail) (7) which provides voice / faxmail service. Consists of.

When providing a voice mail service to a subscriber in the mobile communication switch configured as described above, the ASS-M (3) plays a role in originating and processing the voice mail request of the subscriber, and the number translation processor (NTP) in the INS 8 is used. : Number Translation Processor) is responsible for batch translation of the number and determines the voicemail call, and provides the actual voicemail service in ASS-V / F (7) where the VMS system is implemented.

Hereinafter, a voice mail service device according to the related art will be described in detail with reference to FIG. 2.

FIG. 2 is a view showing a single VMS mounted in a switch according to the prior art, and is composed of an originating block 10, a number translation block 20, and a VMS system 30. The originating block 10 corresponds to ASS-M, which is a device for accessing a base station of a mobile subscriber in a configuration block of an exchange, and sends a signal requesting translation of a number of a call originated from a subscriber or provides a VMS service. Send a signal requesting resource occupation.

The number translation block 20 is a number translation processor (NTP) within an INS (Interconnection Network Subsystem) in the exchange, and is a block for determining that the call attempted by the originating block is a VMS call.

In addition, the ASS-V / F 30 is a block in which a VMS system that directly provides a voice mailbox service is implemented.

Referring to the processing method of a single VMS system according to the prior art configured as described above are as follows.

3 is a call flow diagram of FIG. 2, where a VMS call requesting voicemail service is attempted through originating block 11 when the subscriber cannot make a real time call with the other party. The name of the VMS request signal is EnBlocTranRQ, which is an enblock translation request, which means a batch number translation request.

Subsequently, the received number translation block 21 translates the required call from the subscriber to determine that it is a VMS call requesting voicemail service, and then sends a signal indicating the originating block 11 to the VMS call. The name of this signal is VMSCallRP (VMS Call Response), which is a VMS call response.

In addition, the originating block sends a CdVmsSzRQ, which is a procedure request signal that occupies a VMS resource, to the VMS block 31 to provide a voicemail service function to the subscriber.

However, since the prior art as described above can process only one VMS system, if the VMS system is overloaded due to an increase in subscribers, there is a problem that the voicemail service function cannot be smoothly implemented.

Accordingly, the present invention has been proposed to solve the above problems according to the prior art, and an object of the present invention is VMS (voice mailbox) as the capacity of the voice mailbox service increases due to the increase of mobile subscribers. When the system is expanded, multiple VMSs in the mobile switching center that allow the VMS call to be sent to each ASS-V / F by assigning the corresponding ASS-V / F to different VMS numbers to handle multiple VMS systems. It is to provide a processing method of the system.

Hereinafter, a method of processing a multiple VMS system in a mobile communication switch according to the present invention will be described in detail with reference to the accompanying drawings.

4 is a diagram showing a state in which multiple VMSs are mounted in an exchange according to the present invention, and is composed of an origination block 100, a number translation block 200, and a VMS block 300. The originating block 100 corresponds to ASS-M, which is a device for accessing a base station of a mobile subscriber in a configuration block of an exchange, and sends a signal requesting translation of a number of a call originated from a subscriber or provides a voicemail service. Sends a signal requesting the occupation of a VMS resource.

The number translation block 200 is a number translation processor (NTP) within an INS (Interconnection Network Subsystem) in the exchange, and is a block for determining that the call attempted by the originating block is a VMS call.

In addition, the VMS block 300 is a block in which a VMS system for directly providing a voice mail service is implemented.

The above configuration is different from the prior art in that two or more VMS systems, which are devices that directly provide voice mailbox services, are provided to eliminate the overload. However, in FIG. 4, two or more VMS implementations are shown as two VMSs for convenience of expression.

However, when two or more VMS systems are installed in the exchange as described above, the VMS call must be classified and processed according to each ASS-V / F. Because, when there is only one VMS system, only a procedure request call for occupying the VMS resource needs to be delivered to the ASS-V / F in which the VMS system is implemented. However, when there are a plurality of VMS systems according to the present invention, the VMS system is called. This is because it is necessary to determine which VMS system should receive the procedure request before the call is received.

Hereinafter, a method of distinguishing and processing VMS calls according to respective ASS-V / Fs will be described with reference to FIG. 5 with reference to an embodiment.

5 is a call flow diagram in FIG.

First, the subscriber generates a VMS call requesting voicemail service. In this case, the VMS call must be able to distinguish a number of VMS systems, so before the call can be made, a VMS number (VMS prefix) must be generated. The VMS number can be classified by classifying ASS-V / F in the exchange according to each VMS system. Create That is, the use of the VMS number in distinguishing a plurality of ASS-V / F. The generated VMS call is then sent to the number translation block 21-1 through the originating block 11-1. In the above, the VMS request signal is EnBlocTranRQ (Enblock translation request).

For example, suppose one of the ASS-V / Fs is called ASS 2 and the other is called ASS 3. In generating the VMS number, since the VMS call must be able to distinguish a plurality of ASS-V / F, assume that the VMS number connected to ASS 2 is 190333 and the VMS number connected to ASS 3 is 190444. Register.

Subsequently, if the subscriber issues a voice mail service request call (VMS call) with the VMS number 190333, the originating block sends a VMS request signal having the VMS number to the number translation block.

Subsequently, the number translation block 21-1 receiving the VMS call determines that the signal received from the originating block is a VMS call requesting provision of a voice mailbox service, and at the same time, which of the plurality of VMS systems should be received. Judging is based on the sent VMS number (VMS prefix).

According to the above embodiment, in the number translation block, the call requested from the originating block is the voicemail service request call, and since the VMS number is 190333, it is determined that the signal should be received by ASS 2 where the corresponding number is registered. Therefore, the ASS number including the VMS system to be received is notified to the originating block 11-1. Here, the signal transmitted to the originating block is VmsCallRP (VMS call response).

Subsequently, the originating block 11-1 receives a signal for occupying the corresponding VMS resource by receiving a notification from the number translation block that the call requested from the subscriber is a VMS call and which VMS system should be forwarded to the ASS-V / F. Send to the incoming VMS block 31-1.

According to the above example, since the VMS call requested by the subscriber has a number of 190333 and therefore should be forwarded to ASS 2, the originating block sends an incoming VMS occupancy request signal (CdVmsSzRQ) to occupy the resources of the VMS system corresponding to ASS 2. .

Subsequently, the VMS system (received VMS block) 31-1 receiving the final request signal provides the voice mail service requested by the subscriber.

6 is a flowchart illustrating a processing method of a multiple VMS system in a mobile communication switch according to the present invention.

First, when generating the VMS number in step S111 to register the ASS-V / F to distinguish a plurality of VMS system.

Subsequently, in step S113, a call is attempted with a VMS number in which the calling block is registered in advance.

Next, in step S115, the number translation block determines that the call is a VMS call, and at the same time determines which VMS system should be called based on a pre-registered VMS number and informs the originating block.

Subsequently, in step S117, the originating block sends a signal requesting the occupation of the VMS resource, so that the VMS call is received at the corresponding ASS-V / F.

As a result, the processing method of the multiple VMS system in the mobile communication switch according to the present invention is different from that of the single VMS system according to the prior art, and each ASS- is applied to the VMS signal when a plurality of VMS systems are mounted in the switch. By distinguishing between multiple ASS-V / Fs by assigning a number that distinguishes V / F, there is a key to enabling multiple VMS systems to distribute the overload caused by a single VMS system.

In the method of processing a multiple VMS system in an exchange of a mobile communication system according to the present invention as described above, when the VMS system is expanded as the processing capacity of a voice mail service increases due to the increase in the number of mobile subscribers, By assigning the corresponding ASS-V / F to each different VMS number for processing, the VMS call can be received by each ASS-V / F, so that many VMS systems can be added to the mobile exchange. The advantage is that it can provide enhanced exchange add-ons.
