Description

System, apparatus and method for delivering short message service

The present invention relates to a short message processing system, apparatus and method, and more particularly, to a short message processing system, apparatus and method capable of efficiently processing a short message incoming to a 3G new subscriber assigned a 010 station number of 2G. It is about.

The number portability service refers to a system that allows a subscriber to use an existing phone number even if the mobile service subscriber changes the mobile operator, the type of mobile communication service, and the location of the service. And number portability services for mobile phones.

In the number portability service for mobile phones, the information of the number mobile subscriber is stored in the Master Number Portability DB (hereinafter referred to as 'Master NPDB') of the Korea Telecommunications Business Association (hereinafter referred to as 'KTOA'). Stored and managed. The master NPDB is synchronized with a local number portability database (hereinafter referred to as a "local NPDB") that is independently established in each mobile carrier. Each mobile service provider uses a local NPDB to process voice, short message service (SMS), and multimedia messaging service to number mobile subscribers.

The short message call processing process for number mobile subscribers is as follows. A step in which a calling company checks a called party's network by checking a telephone number of a called terminal in a short message sent from a calling terminal, and the calling company sends a DELIVER message containing information about the called carrier's network. Transmitting to an SMS processing server for processing a Short Message Service (SMS); transmitting a SUBMIT message to a Short Message Service Center (SMSC) of a called operator; and SMSC SUBMIT Depending on the network information of the called party included in the message, the home location register of the second generation mobile communication network (hereinafter referred to as "2G HLR") or the home location register of the third generation mobile communication network (hereinafter referred to as "3G HLR"). Requesting location information of the called terminal to the terminal; transmitting a short message to the called terminal based on the acquired location information of the SMSC; Achieved.

If the location information of the called terminal cannot be obtained from the 2G HLR or the 3G HLR, the SMSC requests the local NPDB of the called terminal to retrieve the number portability of the called terminal. If the receiving terminal receives a response from the local NPDB, the SMSC transmits a REPORT message indicating that the terminating terminal has ported the number to the calling provider's mobile communication network. Then, the calling service provider queries his local NPDB, acquires network property information of the called party, and transmits a DELIVER message including the obtained network property information to the called party.

On the other hand, as the 010 integrated station number policy is implemented, the country assigns 010 station number for each telecommunication company. The 010 station number assigned to each mobile operator is divided into a number band for 2G and a number band for 3G. However, due to the increase in the number of subscribers using 3G, as the 010 number resources allocated to 3G are depleted, each mobile service provider processes 2G 010 number resources to be used by subscribers using 3G as well as subscribers using 2G. . In other words, by assigning a 2G station number 010 to a new subscriber to use 3G, and then register the network attribute information of the new subscriber as 3G in its local NPDB, the new subscriber is treated as a number portable subscriber. In this case, the subscriber recognizes himself as a "3G new subscriber," but the subscriber is registered as a "subscriber who has moved to 3G," not the "3G new subscriber" internally. In the following description, despite being a new subscriber to the company's 3G, due to the depletion of the 010 station number assigned to the company's 3G, the subscriber assigned to the station's 010 station number of the company's 2G is referred to as "a 3G new subscriber who has been assigned the station number of 2G." It will be called.

However, the network attribute information of the 3G new subscriber who has been assigned the 010 station number of 2G is recorded only in the local NPDB of the mobile communication business, and is not recorded in the master NPDB. Therefore, when performing the short message incoming process for the 3G new subscriber who has been assigned the 010 station number of 2G, since the network attribute information of the called terminal must be determined by the called party, there is a problem that the load on the system increases. For a detailed description thereof, reference will be made to FIGS. 1 and 2.

Figure 1 shows a conventional short message incoming processing process for the 3G new subscriber assigned the 010 station number of the 2G, Figure 2 is a short message when the 3G new subscriber assigned the 010 station number of the 2G to the other party It shows the process of message incoming.

As can be seen in Figures 1 and 2, the SMSC should query both 2G HLR and 3G HLR (S13 to S18), or query the 2G HLR (S33 to S36) for short message incoming processing. Therefore, there is a problem that not only the interworking load between the SMSC and the HLR increases but also the processing load of the SMSC when the short message is received.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and is a short message processing system and apparatus capable of reducing the processing load of a mobile communication system and efficiently processing a short message incoming even for a 3G new subscriber assigned a 2G station number 010.

3 is a diagram schematically showing the configuration of a short message processing system according to an embodiment of the present invention. As shown in FIG. 3, the short message processing system includes a calling terminal (not shown), a calling company's mobile communication network 300, a called terminal 200, and a called operator's mobile communication network 100.

The calling terminal and the called terminal 200 are mobile terminals provided with a mobile communication service, and may include personal digital assistants (PDAs), computers, and the like, as well as devices used for wireless communication. Can be. The mobile terminal may be fixed or mobile, and may be referred to as terms such as mobile station (MS), user equipment (UE), subscriber station (SS), wireless device, etc., but is not limited thereto.

Since the caller's mobile communication network 300 is similar in configuration to the caller's mobile communication network 100, the following description will focus on the caller's mobile communication network 100.

The mobile operator's mobile communication network 100 is a third generation mobile communication network, which includes a base station (RNS: Radio Network Subsytem) 111 and a base station controller (RNC: Radio Network Controller, 112). MSC: Mobile Switching Center (120), 3G Home Location Register (140G HLR) (140), Short Message Service Center (SMSC) 130, Short Message Service Gateway (SMS GW) The gateway 160 may include a local NPDB 150 and a short message processing device 400. The SMSC 130, the SMS GW 160, the short message processing device 400, and the like are communication protocols for a short message service (SMS), and are a short message peer to peer (SMPP) or short message client (SMCI). Interface).

The RNS 111 may transmit / receive various signals and data with the mobile terminal 200 in an area (Cell) managed by the RNS 111, and may perform a role such as wireless channel management in the RNS 111. The base station may also be referred to as terms such as node-B, base transceiver system (BTS), and access point.

The RNC 112 may control the RNS 111 and manage radio resources. More specifically, the RNC 112 may instruct the RNS 111 to allocate a communication channel to the mobile terminal 200 and control the transmission output of the RNS 111. In addition, the RNC 112 may support handoff for the mobile terminal 200 moving between the RNS 111.

The MSC 120 may also be referred to as a 'speech switch' and may be connected to one or more RNCs 112 to relay communications between the mobile terminal and other mobile terminals. In addition, the MSC 120 may serve as a service switching point (SSP) for providing an intelligent network service. For example, the subscriber's incoming and outgoing call processing, location registration procedure, and handoff procedure processing. In addition, interworking with external networks can be performed. In addition, the MSC 120 may perform a function of a visitor location register (VLR).

The 3G HLR 140 stores and manages the location information of the subscriber (for example, the address of the VLR, the MSC 120 address, status information, etc. where the destination terminal 200 is currently located), and requests this information. To the system that is doing this. In addition, the 3G HLR 140 stores information necessary for the subscriber to receive communication service, such as subscriber additional service information, in a database, and if necessary, transmits the information to the MSC 120 or the VLR so that the subscriber can receive the additional service. Support.

The SMSC 130 transfers a short message between the called terminal 200 and the calling terminal or between the called terminal 200 and the short message entities (SME). The SMSC 130 has a short message storage / management function, a short message transmission function, and the like. For example, when the called terminal 200 cannot receive a short message, the SMSC 130 stores the short message until the called terminal 200 can receive the short message and then delivers the short message. In addition, the SMSC 130 may transmit a short message to the called terminal 200 in a call. If the short message transmission fails, the SMSC 130 may attempt to retransmit a predetermined number of times at a predetermined time interval. The SMSC 130 may be connected with the 3G HLR 140 and the MSC 120. As such, the SMSC 130 may determine the location of the called terminal 200 and transmit a short message to the called terminal 200.

The SMS GW 160 serves to interwork the SMSC 130 and the short message processing device 400. For example, the SMS GW 160 transfers the SUBMIT message received from the short message processing device 400 to the SMSC 130. As another example, the SMS GW 160 transmits a REPORT message received from the SMSC 130 to the short message processing apparatus 400.

The short message processing apparatus 400 is located between the mobile communication network 100 of the called operator to which the called terminal 200 belongs and the mobile communication network 300 of the calling operator to which the calling terminal belongs, and the short message to the called terminal 200. Perform incoming call processing.

In detail, when the short message processing apparatus 400 receives the DELIVER message from the calling operator's mobile communication network 300, the short message processing apparatus 400 checks a routing digit field and a phone number field in the DELIVE message. Here, the routing digit field refers to a field in which the identifier of the last recipient to which the number is moved is recorded when the called terminal 200 is number-shifted.

Prior to describing a specific operation of the short message processing apparatus 400, the structure of the SMPP message defined in the SMPP will be briefly described. Although not shown in the figure, the SMPP message is composed of a header and a body.

The header may include a length field in which the total length of the SMPP message is recorded, an identifier field in which an identifier for the SMPP message is recorded (for example, in the case of a DELIVER message, an identifier indicating a DELIVER message may be recorded in the identifier field), and the SMPP Status field in which information about success / failure for the request is recorded (for example, in the case of a request message among SMPP messages, a "null" value is recorded in the status field), an SMPP request message with an associated purpose and SMPP A sequence number field in which a sequence number for identifying the response message is recorded.

The body includes mandatory parameters in which essential parameters related to the short message service are recorded, and optional parameters in which optional parameters related to the short message service are recorded. As a representative example of the fields included in the mandatory parameter area, a calling number field in which the telephone number of the calling terminal which has sent the short message is recorded, and a called number field in which the telephone number of the called terminal 200 which is to receive the short message is recorded. For example, the Routing Digit field may be used.

When the short message processing apparatus 400 receives the DELIVER message from the calling operator's mobile communication network 300, the short message processing apparatus 400 checks the routing digit field and the telephone number field in the received DELIVE message.

As a result of the check, when the value of the routing digit of the called terminal is "null" and the telephone number of the called terminal is the 010 station number of the company's 2G, the short message processing apparatus 400 sends the called terminal 200 to its local NPDB 150. Request number port search of).

In response to the telephone number inquiry request, when the number porting query result including the network attribute information of the called terminal 200 is received from the local NPDB 150, the short message processing device 400 receives the received number porting query result. According to the routing information field of the SUBMIT message, the network attribute information of the called terminal 200 is recorded and transmitted to the SMSC 130, or the originating operator sends a REPORT message indicating that the called terminal 200 has moved to another mobile carrier number. It can be delivered to the mobile communication network (300). A more detailed description of the short message processing apparatus 400 will be described later with reference to FIGS. 4 and 5.

The local NPDB 150 may store subscriber information (eg, network attribute information) for a 3G new subscriber who has been assigned 010 station number of its 2G. Here, "3G new subscriber assigned to 010 station number of 2G company" means that although it is a new subscriber to 3G company due to exhaustion of 010 station number assigned to 3G company, it has been assigned 010 station number of 2G company. Means subscriber.

Next, the short message processing apparatus 400 according to an embodiment of the present invention will be described with reference to FIGS. 4 and 5.

4 is a diagram schematically showing the configuration of a short message processing apparatus 400 according to an embodiment of the present invention. As illustrated in FIG. 4, the short message processing apparatus 400 may include a storage unit 440, a first communication unit 410, a second communication unit 430, and a processing unit 420.

The storage unit 440 may store algorithms or data necessary for the short message processing apparatus 400 to operate, and data received from the outside. The storage unit 440 may be a nonvolatile memory such as Erasable Programmable Read Only Memory (EPROM), Electrically Erasable Programmable ROM (EEPROM), Flash memory, or random access memory (RAM). Or a combination of a nonvolatile memory and a volatile memory, or a storage medium such as a hard disk.

The first communication unit 410 may be responsible for transmitting and receiving data or control signals between the short message processing apparatus 400 and the external network. For example, the first communication unit 410 may receive a DELIVER message from the calling operator's mobile communication network 300 and transmit a REPORT message received from the SMS GW 160 to the calling operator's mobile communication network 300. .

The second communication unit 430 may be responsible for transmitting and receiving data or control signals between the short message processing apparatus 400 and the SMS GW 160. For example, the second communication unit 430 may transmit a SUBMIT message including network attribute information of the called terminal 200 to the SMS GW 160 and receive a REPORT message from the SMS GW 160.

The processor 420 may connect and control the components constituting the short message processing apparatus 400 with each other. For example, when the processor 420 receives a DELIVER message from the calling operator's mobile communication network 300, the processing unit 420 determines whether the destination terminal 200 is a 3G subscriber assigned to the 010 station number of the company 2G. To this end, the processor 420 checks a routing digit of the called terminal 200 and a phone number of the called terminal 200 among information included in the received DELIVER message. And according to the check result, the local NPDB 150 can request the number porting query of the destination terminal 200. A detailed description thereof will be described later with reference to FIG. 5.

Each component constituting the short message processing apparatus 400 shown in FIG. 4 may be implemented as a module. Herein, the term 'module' refers to a hardware component such as software or a field programmable gate array (FPGA) or an application specific integrated circuit (ASIC), and a module plays a role. However, a module is not limited to software or hardware. A module may be configured to reside on an addressable storage medium and may be configured to execute one or more processors. Thus, as an example, a module may include components such as software components, object-oriented software components, class components, and task components, and processes, functions, properties, procedures, subroutines, and the like. , Segments of program code, drivers, firmware, microcode, circuits, data, databases, data structures, tables, arrays, and variables. The functionality provided by the components and modules may be combined into a smaller number of components and modules or further separated into additional components and modules.

5 is a flowchart illustrating an operation of the short message processing apparatus 400 according to an embodiment of the present invention. The steps illustrated in FIG. 5 may be performed by the processing unit 420 of the short message processing apparatus 400 illustrated in FIG. 4.

When the DELIVER message is received from the calling operator's mobile communication network 300, the processor 420 checks the routing digit of the called terminal 200 and the telephone number of the called terminal 200 among the information included in the received DELIVER message. do.

As a result of the check, when the value of the routing digit of the called terminal 200 is not "null" (S511, No), or the telephone number of the called terminal 200 is not the 010 station number of the company 2G (S512, No), the processing unit 420 records "null" in the Routing Digit field of the SUBMIT message. This SUBMIT message is sent to the company SMSC 130 via the company SMS GW 160 (S520).

As a result of the check, when the value of the routing digit of the called terminal 200 is "null" (S511, Yes), and the telephone number of the called terminal 200 is the 010 station number of the company's 2G (S512, Yes), the processing unit 420 The company may request a number porting inquiry of the called terminal 200 to its local NPDB 150 (S513).

As a response to the number porting inquiry request, when a number porting inquiry response including the network attribute information of the called terminal 200 is received, the processor 420 generates an appropriate message according to the received number porting inquiry response.

If the receiving terminal 200 receives a response indicating that the destination terminal 200 has moved to its 3G as a number porting inquiry response (S514, YES), the processing unit 420 records the identifier of the 3G in the routing digit field of the SUBMIT message. , To the SMSC 130 of the company. In this case, the SUBMIT message may be delivered to the SMSC 130 via the SMS GW 160. Then, the SMSC 130 transmits a location information request message to the 3G HLR 140 requesting location information of the called terminal 200. As a response to the location information request message, when a location information response message including the location information of the called terminal 200 is received from the 3G HLR 140, the SMSC 130 may transmit a short message to the called terminal 200. have.

If, as a number porting inquiry response, the receiving terminal 200 does not receive a response indicating that the number has moved to its 3G (S514, no), the processing unit 420 moves the receiving terminal 200 to its 2G number. It is checked whether the response has been received (S516).

As a result of checking in step S516, if the receiving terminal 200 receives a response indicating that the number has moved to its 2G (S516, YES), the processor 420 records the identifier of the 2G in the routing digit field of the SUBMIT message. In operation S517, the SMSC 130 transmits the message to the SMSC 130. At this time, the SUBMIT message is delivered to the SMSC 130 via the SMS GW (160). Then, the SMSC 130 transmits a location information request message to the 2G HLR (not shown) requesting the location information of the called terminal 200. As a response to the location information request message, when a location information response message including the location information of the called terminal 200 is received from the 2G HLR, the SMSC 130 may transmit a short message to the called terminal 200.

As a result of checking in step S516, if the receiving terminal 200 does not receive a response that the number has moved to its 2G (S516, no), the processing unit 420 responds that the receiving terminal 200 has moved to the other party. Check whether the received (S518).

As a result of checking in step S518, if the receiving terminal 200 receives a response indicating that the number has been moved to the third party (S518, YES), the processing unit 420 may call the receiving terminal 200 in the status field of the REPORT message. The result value indicating the movement is recorded and transmitted to the mobile communication network 300 of the calling operator (S519).

As a result of checking in step S518, if the receiving terminal 200 does not receive a response that the number has been moved to the other company (S518, no), the receiving terminal 200 corresponds to the case that the number does not move. Therefore, the processor 420 records "null" in the routing digit field of the SUBMIT message and transmits it to the SMSC 130 of the company (S520).

FIG. 6 is a flowchart illustrating a short message processing process performed in the short message processing system of FIG. 3, and illustrates a short message incoming process for a 3G new subscriber of the 2G having its 010 station number assigned thereto.

First, when a DELIVER message is received from the mobile operator's mobile communication network 300 (S601), the short message processing apparatus 400 requests the local NPDB 150 of the destination terminal 200 to search for the number transfer of the destination terminal 200 (S602). ).

The local NPDB 150 transmits, to the short message processing apparatus 400, a number transfer inquiry response indicating that the destination terminal 200 has moved to its 3G number as a response to the number transfer inquiry request (S603).

When a number porting inquiry response is received from the local NPDB 150, the short message processing apparatus 400 records an identifier for its 3G in the routing digit field of the SUBMIT message and transmits it to its SMS GW 160 ( S604).

The SMS GW 160 transmits the SUBMIT message received from the short message processing device 400 to its SMSC 130 (S606).

The SMSC 130 checks the routing digit field of the SUBMIT message received from the SMS GW 160. As a result of the check, since the identifier for the 3G is recorded in the routing digit field, the SMSC 130 requests the 3G HLR 140 of the 3G HLR 140 for location information of the called terminal 200 (S607).

The 3G HLR 140 transmits a location information response including the location information of the called terminal 200 to the SMSC 130 as a response to the location information request (S608).

The SMSC 130 obtains the location information of the called terminal 200 from the received location information response, and transmits a short message to the called terminal 200 based on the obtained location information (S609). Although not shown in the figure, the short message transmitted from the SMSC 130 is transmitted to the called terminal 200 via the MSC 120, the RNC 112, and the RNS 111.

When the reception of the short message is completed, the SMSC 130 records a value indicating completion of the reception of the short message in the status field of the REPORT message, and transmits the REPORT message to the SMS GW 160 (S609).

The SMS GW 160 transmits the REPORT message received from the SMSC 130 to the short message processing apparatus 400 (S610), and the short message processing apparatus 400 sends the REPORT message received from the SMS GW 160. The operator transmits to the operator's mobile communication network 300 (S611).

The short message reception process as shown in FIG. 6 can be equally applied to subscribers who have been assigned the 010 station number of their 2G as well as subscribers who have been assigned the 010 station number of their 2G to their 3G. have.

FIG. 7 is a flowchart illustrating a short message incoming process performed in the short message processing system of FIG. 3, and illustrates a short message incoming process when a 3G new subscriber to whom a 2G station number of its 2G has been assigned moves to a third party. One flow chart.

When the DELIVER message is received from the calling operator's mobile communication network 300 (S701), the short message processing apparatus 400 requests the local NPDB 150 of the destination terminal 200 to search for the number movement of the called terminal 200 (S702).

The local NPDB 150 transmits, to the short message processing apparatus 400, a number porting inquiry response indicating that the destination terminal 200 has moved to a third party as a response to the number porting inquiry request (S703).

When the number transfer inquiry response is received from the local NPDB 150, the short message processing apparatus 400 records a value indicating that the called terminal 200 has moved to a third party in the status field of the REPORT message. The REPORT message is transmitted to the mobile communication network 300 of the calling operator (S704).

With reference to FIGS. 6 and 7 above, a short message incoming process for 3G new subscribers assigned to their 2G station 010 and a case where 3G new subscribers assigned to their 2G 010 station number are moved to a third party.
