The present invention relates to a short message processing method, and more particularly, to a method for processing a short message received by a synchronous network subscriber, an asynchronous network subscriber or a number mobile subscriber in a mobile communication system in which a synchronous network and an asynchronous network are mixed.

At present, the mobile communication service is newly introduced with the North American CDMA (2G network) and the European WCDMA (3G network). On the other hand, since the CDMA network uses the synchronous North American standard protocol in the core network portion, the WCDMA network uses the European protocol, so the system providing the service in the CDMA network and the system providing the service in the WCDMA network are the protocol. These are different and are not compatible with each other and must be configured separately.

Therefore, SMSC for short service should also be installed in CDMA network and WCDMA network respectively. SMSC of WCDMA network performs message routing between WCDMA network and CDMA network to minimize network design cost. In order to do this, it implements both CDMA protocol and WCDMA protocol. In this sense, WCDMA SMSC is called Dual Stack SMSC (DSMSC).

However, by using the dual stack SMSC, SMS service processing between the CDMA network and the WCDMA network is possible only when the mobile terminal number band used in the CDMA network and the mobile terminal number band used in the WCDMA network can be distinguished. According to the mobile policy, even if the subscriber information of the mobile communication terminal cannot confirm the subscription information of the mobile communication terminal, even if the dual stack SMSC is used, the SMS interworking processing between the synchronous network and the asynchronous network becomes impossible.

In order to overcome this problem, both SMSC of CDMA network and SMSC of WCDMA network should be dual stack, but this requires considerable system upgrade cost and time, and investment cost in the present situation where there are not many subscribers of WCDMA network. There is a drawback to this excess.

The present invention has been made to overcome the problems and disadvantages described above, the WCDMA SMSC is built in a dual stack, the CDMA SMSC is a number shifted from the CDMA network to the WCDMA network or from the WCDMA network to the CDMA network while maintaining the existing configuration The technical problem is to make it possible to accurately send the incoming SMS to the subscriber.

Another technical problem of the present invention is to enable SMS transmission for number mobile subscribers while minimizing change in mobile communication system.

In the short processing method according to the first embodiment of the present invention for achieving the above technical problem, after the 2G exchanger receives the SMS from the calling terminal, the prefix of the called terminal is extracted and the prefix of the extracted terminal is a 2G network number. Confirming the first step; If the called terminal number is a 2G network number, a second step in which the 2G exchange sends an SMS to the 2G SMSC; A third step of the 2G SMSC querying the subscriber information with the DHLR; A fourth step of checking, by the 2G SMSC, whether the called terminal has a number ported; A fifth step of transmitting, by the 2G SMSC, the SMS to the DSMSC when the called terminal is a number mobile terminal; A sixth step of the DSMSC querying the DHLR for routing information; And a seventh step of transmitting, by the DSMSC, the SMS to the called terminal according to the routing information inquired by the DHLR.

In addition, the present invention is a short processing method according to a second embodiment of the present invention comprises a first step of transmitting to the DSMSC after receiving the SMS from the originating terminal 3G switch; A second step of extracting, by the DSMSC, the prefix of the called terminal and confirming that the number of the band used in the 3G network; A third step of the DSMSC requesting subscriber information to the DHLR and receiving a response when the called terminal number is a 3G network number; And a fourth step of transmitting, by the DSMSC, an SMS through an exchange to which the called terminal is connected with reference to subscriber information received from the DHLR.

In addition, the short message processing method according to the third embodiment of the present invention includes a first step of extracting a prefix of a called terminal by a 2G SMSC as the SMS server sends an SMS; A second step of the 2G SMSC querying the subscriber information with the DHLR; A third step of checking, by the 2G SMSC, whether the called terminal has a number; A fourth step of transmitting the SMS to the DSMSC by the 2G SMSC when the called terminal is a number porting terminal; A fifth step of the DSMSC querying the routing information with the DHLR; A sixth step of transmitting, by the DSMSC, the SMS to the called terminal according to the routing information inquired by the DHLR; A seventh step of reporting, by the DSMSC, the SMS processing result to the 2G SMSC; And an eighth step of the 2G SMSC reporting the SMS processing result to the SMS server.

In addition, the short message processing method according to the fourth embodiment of the present invention includes a first step of extracting the prefix of the destination terminal by the DSMSC as the SMS server sends the SMS; A second step of the DSMSC requesting subscriber information to the DHLR and receiving a response thereto; A third step of transmitting, by the DMSC, an SMS through an exchange to which the called terminal is connected with reference to subscriber information received from the DHLR; And a fourth step of the DSMSC reporting the SMS processing result to the SMS server.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description, the exchange and short service center of the CDMA network will be referred to as 2G MSC and 2G SMSC, and the switch and short service center of the WCDMA network will be referred to as 3G MSC and DSMSC.

1 is a block diagram of a mobile communication system to which the present invention is applied.

The synchronous network of the mobile communication system to which the present invention is applied includes a plurality of 2G exchangers (2G MSC, 20) and a plurality of 2G short message service centers (2G SMSC, 22), and the asynchronous network includes a plurality of 3G exchangers (3G MSC, 30) and a plurality of dual stack short service centers (DSMSC) 32, wherein the 2G SMSC 22 and DSMSC 32 share a dual stack home location register (DHLR) 10.

Each switch 20 and 30 transmits the call to the 2G SMSC 22 or the DSMSC 32 when the call is made from the mobile communication terminal, and the 2G SMSC 22 and the DSMSC 32 respectively process the short message according to the SMS called number. Perform Such short processing is performed differently according to the type of the called terminal. The called terminal may be, for example, a synchronous network subscriber terminal existing in a synchronous network, a subscriber terminal numbered to a synchronous network or an asynchronous network existing in an asynchronous network, and synchronized. It may be an asynchronous network subscriber station existing in a network or an asynchronous network, or a subscriber station which has been ported to a synchronous network existing in a synchronous network. The short text processing method in each case will be described later with reference to FIGS. 2 and 3.

Meanwhile, the 2G SMSC 22 and the DSMSC 32 are connected to the SMS server 40, and the SMS server 40 sends the SMS transmitted from the Internet or another carrier server to the 2G SMSC 22 or DSMSC 32. SMS is transmitted to the called terminal.

In order to transmit SMS to a mobile communication terminal including a number mobile subscriber station in a mobile communication system in which a synchronous network (2G network) and an asynchronous network (3G network) are mixed, the DHLR 10 receives the subscription network information and the SMS of the mobile communication terminal. SMSC ID information to be routed is stored and managed in the subscriber information DB 12 for each prefix of the mobile communication terminal. In addition, the 2G SMSC 22 stores and manages the DSMSC ID information to be routed for each prefix of the mobile communication terminal in the prefix DB 24, and the DSMSC 32 stores the 2G SMSC ID and DSMSC ID to be routed for each prefix of the mobile communication terminal. Is stored and managed in the prefix DB 34. Here, the prefix DB 24 of the 2G SMSC 22 may be implemented to manage only information on 3G network subscribers.

Table 1 shows an example of the prefix DB 24 of the 2G SMSC 22, and Table 2 shows an example of the prefix DB 34 of the DSMSC 32.

TABLE 1

Prefix Joining network (3G) 011293 SMSC # 30 016 SMSC # 30 01031 SMSC # 20 01020 SMSC # 20

Since the 2G SMSC 22 and the DSMSC 32 manage the prefix-specific SMSC ID as described above, the 2G SMSC 22 may transmit an SMS to the corresponding DSMSC when receiving the SMS to be transmitted to the 3G network subscriber. In addition, when receiving the SMS, the DSMSC 32 may transmit the SMS to the corresponding switch or forward the SMS to the 2G SMSC according to the subscription network information of the called terminal.

Hereinafter, an SMS processing method of the mobile communication system shown in FIG. 1 will be described. When the mobile communication terminal existing in the 2G network sends an SMS (FIG. 2), the mobile communication terminal existing in the 3G network is SMS. In the case of sending (FIG. 3), the SMS server will be described by dividing the SMS to the 2G network (FIG. 4) and the SMS server to send the SMS to the 3G network (FIG. 5).

Short Message Processing Process when Sending Short Message in 2G Network

2 is a flowchart illustrating a short message processing method according to a first embodiment of the present invention.

In this embodiment, the calling terminal is located in a synchronous network (a synchronous network subscriber terminal in a synchronous network, an asynchronous network subscriber terminal in a synchronous network, a subscriber terminal number-transferred to an asynchronous network in a synchronous network, and a synchronous network). Any one of the subscriber stations number-transferred to the existing synchronous network), the subscriber terminal number-transferred to the synchronous network subscriber terminal existing in the synchronous network, the synchronous network or the asynchronous network existing in the asynchronous network, synchronous network or asynchronous network The short processing method for the case of any one of the asynchronous network subscriber station existing in the subscriber station and the subscriber terminal number ported to the synchronous network existing in the synchronous network. The table is as follows.

Since the SMS transmitted from the calling terminal in the SMS processing need only be sent to the SMSC through the exchange connected to the calling terminal, the short processing method according to each case of the called terminal will be described.

First, the 2G exchanger receives the SMS from the calling terminal (S101), extracts the prefix of the called terminal, and checks whether the extracted prefix is the 2G network number (S103).

If the check result is the 2G network number, the 2G exchanger sends an SMS to the 2G SMSC (SMDPP) (S105), and the 2G SMSC requests subscriber information to the DHLR and receives a response thereto (S107). At this time, DHLR transmits the subscription network information for the called terminal together (SMS Request Return Result (Subscriber Type)). Then, from the subscriber information received from the DHLR, it is checked whether or not the destination terminal is a subscriber port number ported (S109). As a result of the check, if the subscriber is not a number ported, that is, the receiving terminal is a subscriber to the 2G network, the SMS is transmitted through an exchange to which the called terminal is connected (S111).

FIG. 6 shows parameters included in the subscriber information request message of the SMSC and parameters included in the response message sent by the DHLR to the SMSC in response thereto.

7 illustrates a field structure of the SMS_Subscriber Type parameter, and FIG. 8 illustrates an example of classifying subscriber types according to data field values shown in FIG. 7.

On the other hand, if the result of the check in step S103 is not the 2G network number, that is, the 3G network number, the 2G MSC delivers the received SMS to the DSMSC (SMDPP) (S113). Accordingly, the DSMSC requests subscriber information by receiving the destination terminal number included in the SMS to DHLR and receives a response thereto (S115), and transmits the SMS through an exchange (2G exchange or 3G exchange) to which the destination terminal is connected. It transmits (S117). In this case, when the called terminal exists in the 2G network, the SMS is transmitted through the SMDPP message to the 2G switch, and when the called terminal exists in the 3G network, the SMS is transmitted through the MT_Fwd_SM message.

In addition, if the confirmation result of step S109 is confirmed as a mobile subscriber number, that is, a 3G network subscriber using a 2G network number, the 2G SMSC forwards the SMS to the DSMSC (GW_SMDPP), and receives a response thereto (GW_SMDPP RR (S125), the DSMSC requests routing information to the DHLR (Send Routing Information or SMS) and receives the response (SRI_ack) (S127). Accordingly, the DSMSC transmits the SMS with reference to the received routing information (S129). In step S129, the DSMSC transmits the SMS through the SMDPP message to the 2G switch when the terminating terminal exists in the 2G network, and transmits the SMS through the MT_Fwd_SM message when the terminating terminal exists in the 3G network.

This embodiment is a synchronous network subscriber terminal, synchronous network or asynchronous that the originating terminal exists in the 3G network (a 3G network subscriber terminal or a number mobile subscriber terminal to the 3G network existing in the 3G network), and the destination terminal is in the synchronous network The short processing method for the case of any one of a subscriber station number-transported to an asynchronous network existing in a network, a synchronous network or an asynchronous network subscriber station existing in an asynchronous network, and a subscriber terminal number-transferred to a synchronous network existing in a synchronous network. Indicates. The table is as follows.

TABLE 4

Outgoing terminal Incoming terminal 3G network subscriber terminal in 3G 2G network subscriber terminal in 2G Subscriber terminal number ported to 3G network (2G network / 3G network exists) 3G network subscribers in 3G Subscriber terminal number ported to 2G network (2G network exists) Subscriber's number ported to 3G network in 3G 2G network subscriber terminal in 2G Subscriber terminal number ported to 3G network (2G network / 3G network exists) 3G network subscribers in 3G Subscriber terminal number ported to 2G network (2G network exists)

First, the 3G exchanger receives the SMS from the calling terminal and transmits it to the DSMSC (S201). The received DSMSC extracts the prefix of the called terminal (S203) and checks whether the number of the band used in the 3G network is used (S205). ).

If it is confirmed that the 3G network number, DSMSC requests the subscriber information to DHLR and receives a response (S207). When the called terminal exists in the 2G network, the SMS is transmitted through the SMDPP message to the 2G exchanger, and when the called terminal exists in the 3G network, the SMS is transmitted through the MT_Fwd_SM message (S209).

In addition, if the result of the check in step S205 is not the 3G network number, that is, the 2G network number, the DSMSC forwards the received SMS to the 2G SMSC (SMDPP) (S211). Accordingly, the 2G SMSC transmits the called terminal number included in the SMS to DHLR to request subscriber information and receive a response thereto (S213), and checks whether the corresponding subscriber is a number ported subscriber according to the received subscriber information. (S215).

As a result of the check, if the number is not a mobile subscriber, that is, a 2G network subscriber using a 2G network number, the SMS is transmitted through an exchange (2G switch or 3G switch) to which the corresponding destination terminal is connected (S217).

On the other hand, if the confirmation result of step S215, i.e., a 3G network subscriber using a 2G network number, the 2G SMSC forwards the SMS to the DSMSC (GW_SMDPP) and receives a response thereto (GW_SMDPP RR) (S219 ), The DSMSC inquires the routing information of the destination terminal to the DHLR (S221) and transmits the SMS through the exchange connected to the destination terminal (S223). In this case, the DSMSC transmits the SMS through the SMDPP message to the 2G switch when the terminating terminal exists in the 2G network, and transmits the SMS through the MT_Fwd_SM message when the terminating terminal exists in the 3G network.

In the present embodiment, parameters included in the message GW_SMDPP used when the 2G SMSC transmits the SMS to the DSMSC and parameters included in the response message GW_SMDPP R.R are shown in FIG. 9.

This embodiment shows a short message processing method for a case where an SMS originating subject is an SMS server and a called terminal is a terminal using a synchronization network number band.

First, the 2G SMSC receives the SMS from the SMS server (SMPP) (S301), and extracts the prefix of the called terminal (S303).

The 2G SMSC requests subscriber information to the DHLR and receives a response thereto (S305). At this time, the DHLR transmits subscription network information for the called terminal together (SMS Request Return Result (Subscriber Type)). Then, the 2G SMSC checks whether or not the destination terminal is a number ported subscriber terminal from subscriber information received from DHLR (S307). As a result of the check, if the subscriber is not a number ported, that is, the receiving terminal is a subscriber to the 2G network, the SMS is transmitted through an exchange to which the called terminal is connected (S309).

Here, parameters included in the subscriber information request message of the SMSC and parameters included in the response message transmitted by the DHLR to the SMSC in response thereto are shown in FIG. 6, and the subscriber type according to the field structure and data field values of the SMS_Subscriber Type parameter. An example of division of is as shown in FIGS. 7 and 8.

In addition, when the confirmation result of step S307 is confirmed to be a mobile subscriber, that is, a 3G network subscriber using a 2G network number, the 2G SMSC forwards the SMS to the DSMSC (GW_SMDPP_submit), and receives a response thereto (S311). DSMSC requests routing information to DHLR (Send Routing Information or SMS) and receives the response (SRI_ack) (S313). Accordingly, the DSMSC transmits the SMS with reference to the received routing information (S315). In step S315, the DSMSC transmits the SMS through the SMDPP message to the 2G switch when the terminating terminal exists in the 2G network, and transmits the SMS through the MT_Fwd_SM message when the terminating terminal exists in the 3G network.

Thereafter, the DSMSC reports that the SMS transmission is completed by the 2G SMSC (GW_SMPP_deliver) (S317), and the received 2G SMSC reports the SMS transmission result to the SMS server (S319).

Here, the message (GW_SMPP_submit) that the 2G SMSC sends the SMS to the DSMSC includes the parameters as shown in FIG. 10, and the message (GW_SMPP_deliver) that the DSMSC reports the transmission result to the 2G SMSC after the SMS transmission process is shown in FIG. 11.
