Description

System and method for splitting by a telephone number of a voice mail notification message}

The present invention relates to a voice message notification in a mobile communication network, and more particularly, to a station number separation system of a voice notification message capable of determining a routing path of a voice notification message irrespective of a receiving station number of a voice message server and a short message service center. It's about how.

With the development of mobile communication technology, a personal communication system (PCS), which can satisfy a human desire to communicate freely with anyone at any time and anywhere, has appeared to provide commercial services.

Among the services provided by such a personal communication system, the Short Message Service (SMS) is responsible for sending and receiving text messages between individuals using a point-to-point message delivery method. If the called party does not receive the message sent by the calling party, it accumulates and delivers the corresponding text message for a certain period of time and then attempts to send the text message to the called party. Send it.

The use of such SMS includes a one-way voice mail box and an e-mail call notification function, and includes a two-way phone-to-phone message sending function and a web sending message sending function. Or suitable for application services.

The equipment of such SMS is made through Short Message Service Center (SMSC), which is a TIA / EIA IS-637 CDMA SMS standard. The service method of transmission is called a voice message system (VMS), which is also widely used.

1 is a diagram illustrating a processing procedure between a general VMS and an SMSC.

As shown in FIG. 1, a plurality of VMSs have their respective accommodating station numbers. For convenience of description, the first voice message server VMS1 uses 201 and 503 station numbers, and the second voice message server VMS2 includes a number of receiving stations. Assume that the 301 station number is received by the third voice message server VMS3. In addition, SMSC also has an accommodating station number. In this case, for convenience of explanation, the first short message service center (SMSC1) is 2 ** (where * is any number from 0 to 9). Assume that the short message service center SMSC2 accepts 3 ** station numbers, and the third short message service center SMSC3 accepts 4 ** and 5 ** station numbers.

As shown in Fig. 1, VMS1 is connected to the first short message service center SMSC1, the second voice message server VMS2 is connected to the second short message service center SMSC2, and a third service is opened before the service of the voice message is opened. The voice message server VMS3 is connected to the third short message service center SMSC3. When a particular subscriber leaves a voice message at 201-****, the first voice message server VMS1 sends a voice notification message of the voice message to the connected first short message service center SMSC1, and the first short message service center. (SMSC1) forwards the corresponding voice notification message to the switchboard (PCX2) where the subscriber 201-**** is located to notify the called party that the text message has arrived.

In this case, it is assumed that the traffic to the first short message service center SMSC1 is increased to transfer 203 station number to the second short message service center SMSC2, and the first voice message server VMS1 transfers 201 and 503 station numbers. All are accommodated, and one voice message server (VMS) can only connect to one short message service center (SMSC), so there is no alternative except to transfer the 503 station number to the extended voice message server (VMS).

However, the transfer of voice message server (VMS) has a problem in that network configuration and planning are difficult for mobile operators due to prolonged work time, personal information, especially password exposure and personal information initialization. have.

In addition, the expansion of the short message service center (SMSC) has a problem in that the work of changing the receiving station number is complicated and the TCP / IP connection between the voice message server (VMS) and the short message service center (SMSC) is complicated.

Accordingly, the present invention has been made in an effort to solve such a conventional problem, and an object of the present invention is to provide a routing path for a voice notification message regardless of a receiving station number of a voice message server (VMS) and a short message service center (SMSC). It is to provide a system for separation of voice notification messages using a voice message routing server (VRS) that can be determined.

Another object of the present invention is to provide a method for separating the voice notification message by station number using the voice message routing server (VRS).

At this time, as shown for convenience of description of the present invention, the first voice message server VMS1 has 201 and 503 station numbers, the second voice message server VMS2 has 301 station numbers, and a third voice message server ( It is assumed that VMS3) accepts 401 station number.

The voice message routing server 200 includes a prefix table for storing information for routing a specific station number to a specific short message service center (SMSC), and the voice notification message of the voice message from the voice message server unit 100. As it is received, the voice notification message is output to the short message service center unit 300 by referring to the routing information stored in the prefix table. At this time, the routing information stored in the prefix table can be adjusted by the mobile communication network operator.

For example, when a voice message for a particular station number is congested, the routing path to one SMSC may be converted to another SMSC to prevent traffic generated by being routed to a specific SMSC.

In the present invention, for convenience of explanation, the prefix table has 201 station number in the first short message service center SMSC1, 503 station number in the first short message service center SMSC1, and 301 station number in the second short message service center SMSC2. Assuming that the 401 station number is set to the third short message service center SMSC3, if a specific subscriber leaves a voice message at 201-****, the first voice message server VMS1 is unconditionally voiced.

In addition, the common line signaling method (No. 7) provides a common channel for signal information related to a large number of lines or information necessary for network management. Refers to the signaling method that is transmitted through.

Switch unit 400 is composed of a plurality of exchanges (PCX1, PCX2, ... PCXn), the voice to convert the voice notification message provided from the short message service center unit 300 to the common line signal system (No. 7) The notification message notifies the mobile communication terminal that a voice message has been received.

3 is a view for explaining the voice message routing server (VRS) in more detail.

As shown in FIG. 3, the voice message routing server 200 includes a UNIX computer system 210, a kernel 220, a DB 230, a message storage and routing processor 240, an operation manager 250, and a VMS interface. The unit 260 includes an SMSC interface unit 270, an NMS interface unit 280, and an OA & M interface unit 290.

The UNIX computer system 210 is a substructure of the VMS voice notification message distribution system, and provides a basic operating environment of hardware and software of the VMS voice notification message distribution system, and the kernel 220 uses a UNIX computer system function to interwork application blocks. Allocate communications and resources, and DB 230 stores VMS voice notification messages, operator parameters, and operational management data.

In addition, the message storage and routing processor 240 receives the VMS voice notification message from the VMS, temporarily stores it and routes it to the corresponding SMSC, and the operation manager 250 stores all operation management data necessary for operating the system in a database in real time. And provide it to the operator and the Network Management System (NMS).

In addition, the VMS interface unit 260 provides an interworking function with the VMS with the Short Message Peer to Peer Protocol (SMPP), and the SMSC interface unit 270 provides an interworking function with the SMSC with the SMPP. At this time, access protocol for interworking with VMS and interworking with SMSC use TCP / IP or X.25. X.25 is generally used over LAN and LAN, that is, it is widely used over WAN. There are many protocols such as TCP / IP, IPX, AppleTalk, etc. in LAN, but X.25 is generally used in WAN.

In addition, the NMS interface unit 280 provides an interworking function with the network management system (NMS) of the mobile communication network operator through the TCP / IP Simple Network Management Protocol (SNMP), and the OA & M interface unit. 290 provides an operation environment to the mobile communication network operator in connection with an OA & M center (not shown) for efficient operation and maintenance of the mobile communication network.

Next, the operation of the station-specific separation system of the voice notification message using the VRS shown in FIG. 2 will be described in more detail.

In particular, in the case of applying the present invention, it is assumed that the traffic is increased in the first short message service center SMSC1 and the 503 station number is transferred to the second short message service center SMSC2. Explain.

That is, since each VMS has a queue for voice notification messages provided from a plurality of mobile communication terminals, it is possible to confirm that a lot of traffic load is applied to a specific SMSC by monitoring them. Since the queue exists, you can monitor it to see that the traffic load is high on a particular SMSC.

4 is a diagram illustrating a case where the present invention is applied.

2 and 4, when the short message service center SMSC corresponding to the 503 station number is changed to the second text service center SMSC2 in the prefix table of the VRS, the voice message routing server VRS is expanded. And at any time without change of acceptance. In addition, even if the VMS is expanded, changing the prefix table of VRS does not affect the short message service center (SMSC).

Hereinafter, a method for separating station numbers of voice notification messages according to an embodiment of the present invention will be described.

5A to 5B are flowcharts illustrating a method for separating station numbers by voice number according to an embodiment of the present invention.

As shown in Fig. 5A, the calling mobile terminal first sends a calling mobile terminal identification number (MIN) and a called MIN (step S110).

Then, it is checked whether or not the call can be received (step S115). If the call is possible, the call is received at the exchange side accommodating the called-party mobile communication terminal (step S120). Step S125).

If the switch to the VMS is not performed in step S125, the notification of the corresponding voice notification message is considered to have failed (step S130). If the switch to the VMS is completed, the VMS accepting the called-party mobile communication terminal is searched (step S130). S135).

Then, the voice message is recorded or called by the caller (step S140), and stored in the VMS accommodating the called-party mobile communication terminal (step S145).

Subsequently, the voice notification message is transmitted to the SMSC that accepts the called party's MIN using an application layer protocol called Short Message Peer to Peer Protocol (SMPP) (step S150).

The SMSC then receives the voice notification message (step S155) and obtains the called party's subscriber location information from the HLR with reference to the received voice notification message (step S160).

Subsequently, in step S160, the voice notification message is transmitted to the corresponding switch PCX controlling the mobile communication terminal of the called party subscriber based on the called party subscriber location information obtained from the HLR (step S165), and the exchange receives the voice notification message. Transmits the voice notification message to the called-party mobile communication terminal (step S170).

5B is a flowchart for explaining step S150 of FIG. 5A in more detail.

As shown in Figs. 5A to 5B, as the voice message is recorded by the calling party to the VMS, the destination MIN information is transmitted to the VRS (step S152), and the VRS then prefixes the table (or routing) based on the destination MIN. The IP address of the SMSC registered in the table) is determined, and the voice notification message is transmitted to the corresponding SMSC side (step S154).

Although the above has been described with reference to a preferred embodiment of the present invention, those skilled in the art will be able to variously modify and change the present invention without departing from the spirit and scope of the invention as set forth in the claims below. It will be appreciated.

As described above, since the short message server (VMS) and the short message service center (SMSC) each have an accommodating station number, the establishment of a routing path between these two systems is only dependent on the accommodating station number of the voice message server (VMS). However, according to the present invention, by using a voice message routing server (VRS), which is a system capable of determining a routing path of a voice notification message irrespective of an accommodating station number of the VMS and an SMSC, the station number arrangement of the VMS and the SMSC determined only by the accommodating station number of the VMS is determined. Can be facilitated.

In addition, there is an advantage that it is possible to prevent the exposure of subscriber personal information by changing the acceptance of the VMS station number.

In addition, the existing routing functions for messages delivered to SMSCs and messages delivered by SMSCs as well as VMSs, as well as messages delivered by SMSCs, are not implemented in the system. It can be utilized.
