The present invention relates to a method and system for providing a short message between an asynchronous network and a synchronous network. More specifically, the present invention relates to a method and system for delivering a short message during a call without waiting until the end of the call when the mobile terminal hands over the asynchronous network and the synchronous network during the call.

In recent years, many telecommunication companies have spurred the development of new technology called wireless Internet to provide communication services such as the Internet beyond the space. Wireless Internet refers to an environment and technology in which a user can use an Internet service through a wireless network while using a mobile communication terminal. The development of mobile communication technology and the rapid increase in the penetration rate of mobile communication terminal further promoted the development of this wireless Internet environment.

With the development of the wireless Internet environment, mobile operators and other telecommunication operators are promoting the use of the wireless Internet by providing various and useful services to the users of the wireless Internet. Such wireless Internet services include text messages, e-mails, cards, letters, games, geography / life information, learning, cartoons, and the like.

In particular, a short message service (SMS) refers to a service that delivers a text message of limited length from a computer connected to the Internet to a mobile communication terminal or between mobile communication terminals regardless of whether a mobile subscriber is in a call state. The short message service that can transmit texts of about 80 bytes (80 Korean characters) on the LCD screen of mobile communication terminals has exploded in utilization due to the wide range of use from personal use to corporate use. to be.

On the other hand, the current mobile communication network is operated by the North American synchronous network and the European asynchronous network. In some countries or regions where the synchronous network or the asynchronous network operates independently, the synchronous network and the asynchronous network coexist. There are also countries or regions that operate in the country. When the synchronous network or the asynchronous network is operated independently of each other, a service for handling incoming or outgoing short messages during handover of a mobile communication terminal is provided.

Therefore, it is not efficient to receive or send a short message to a mobile communication terminal where handover occurs. There are disadvantages.

In addition, in describing the present invention, when it is determined that the detailed description of the related well-known configuration or function may obscure the gist of the present invention, the detailed description thereof will be omitted.

1 is a block diagram schematically illustrating a system for providing a short message during handover between an asynchronous network and a synchronous network according to a preferred embodiment of the present invention.

The short message providing system according to the preferred embodiment of the present invention is a system in which the asynchronous network 110 and the synchronous network 120 coexist, and the mobile communication terminal 100 is between the asynchronous network 110 and the synchronous network 120. In the case of handover, a system for providing a short message in real time. Asynchronous network 110 according to a preferred embodiment of the present invention will be described assuming a wideband code division multiple access (WCDMA) network, synchronous network 120 is a CDMA 2000 network. However, the present invention is not limited thereto and may be applied to any type of asynchronous network and synchronous network.

The asynchronous network 110 includes a WCDMA base station (WCDMA BTS) 111, a WCDMA base station controller (WCDMA BSC) 112, a WCDMA mobile switching center (WCDMA MSC) 113, and a short message center (SMC) 114. ), A WCDMA Serving GPRS Support Node (SGSN) 115, a WCDMA Packet Gateway Support Node (GGSN) 116, a Packet Switch Network (PSN) 117, etc. It may include.

The WCDMA base station 111 performs a wireless access termination function with the mobile communication terminal 100 according to the 3rd Generation Partnership Project (3GPP) wireless access standard, and transmits / receives voice, video, and data traffic in a WCDMA manner. It performs and transmits and receives information with the mobile communication terminal 100 through a transmission and reception antenna.

The WCDMA base station controller 112 includes wired and wireless channel management, protocol matching of the mobile communication terminal 100, and protocol matching of the base station. It handles functions such as soft handover processing, core network protocol processing, GPRS (General Packet Radio Service) access, fault management, and system loading. Here, GPRS is an asynchronous communication system that supports a data transmission rate of 115 Kbps, provides a multimedia mail, and maximizes the efficiency of a transmission line by packet data transmission.

The WCDMA mobile switching center 113 additionally has a soft switching structure for speeding up call processing in addition to the basic function for voice communication in the existing Interim Standard (IS) -95B network.

Meanwhile, the WCDMA mobile switching center 113 according to the embodiment of the present invention has an additional function for providing an interworking function of the short message service with the synchronous network 120. That is, the anchor side WCDMA mobile switching center 113 transmits a short message to the mobile communication terminal 100 handing over from the asynchronous network 110 to the synchronous network 120 to the WCDMA BTS 111 and the WCDMA BSC 112. And a protocol processing function for forwarding to the serving side CDMA 2000 mobile switching center 123. Here, the anchor side refers to the mobile communication network before the mobile communication terminal 100 is handed over, and the serving side refers to the mobile communication network after the mobile communication terminal 100 is handed over.

To this end, the WCDMA mobile switching center 113 encodes the received asynchronous short message based on the Global System for Mobile Communications (GSM) -MAP (Mobile Application Part) into the IS-637 format of the synchronous network, and then into the synchronous network 120. It converts the IS-41 Mobile Application Part (MAP) type short message to the CDMA 2000 mobile switching center 123 for delivery.

There is also a routing function for delivering a short message to the switching center. The WCDMA mobile switching center 113 uses a home location register (HLR) (not shown) to identify the CDMA 2000 mobile switching center that controls the area where the mobile communication terminal 100 being handed over is located.

The short message center 114 according to the preferred embodiment of the present invention receives the short message to be transmitted to the mobile communication terminal 100 from the SMS sender side and transmits the short message to the WCDMA mobile switching center 113.

The short message may be transmitted in the form of packet data through a packet switch network (PSN).

Meanwhile, according to the exemplary embodiment of the present invention, the WCDMA mobile switching station 113 converts the GSM-MAP type short message received into the IS-41 MAP type short message, but the present invention is not limited thereto. That is, according to another embodiment of the present invention, the short message center 114 transmits the received GSM-MAP type short message to the WCDMA packet switched support node 115, and the GSM at the WCDMA packet switched support node 115. -MAP type short message may be encoded in IS-637 format of synchronous network 120, and may be converted to IS-41 MAP type short message for delivery to synchronous network 120. Accordingly, the WCDMA mobile switching center 113 transmits the received short message to the CDMA 2000 mobile switching center 123.

On the other hand, as another embodiment of the present invention, there is a case in which a short message is transmitted from the mobile communication terminal 100 handing over from the asynchronous network 110 to the synchronous network 120 to another mobile communication terminal.

In this case, the CDMA 2000 mobile switching center 123 receives the IS-41 MAP type short message from the mobile communication terminal 100 and forwards it to the WCDMA mobile switching station 113. Here, the IS-41 MAP type short message is a short message encoded in the IS-637 format of the synchronous network 120.

The WCDMA mobile switching center 113 converts the received IS-41 MAP type short message into an asynchronous short message that is an asynchronous SMS standard and transmits the short message to the short message center 114. The short message center 114 forwards the received asynchronous short message to the SMS called party.

In this case, the WCDMA mobile switching station 113 converts the received IS-41 MAP type short message into an asynchronous short message, but the present invention is not limited thereto. That is, according to another embodiment of the present invention, the CDMA 2000 mobile switching center 123 transmits the IS-41 MAP type short message to the WCDMA mobile switching center 113, and the WCDMA mobile switching center 113 does not undergo a conversion process. The IS-41 MAP type short message may be directly transmitted to the WCDMA packet switched support node 115, and the WCDMA packet exchange support node 115 may convert the IS-41 MAP type short message into an asynchronous short message. Accordingly, the WCDMA packet switched support node 115 sends the converted asynchronous short message to the short message center 114.

2 is a flowchart illustrating a process of providing an incoming service for transmitting a short message from the asynchronous network 110 to the mobile communication terminal 100 handing over to the synchronous network 120 according to the first embodiment of the present invention.

The WCDMA mobile switching center 113 receives a short message to be sent from the asynchronous network 110 to the SMS terminating terminal handing over to the synchronous network 120 through the short message center 114 (S210). Upon receiving the short message, the WCDMA mobile switching center 113 determines whether the SMS terminating terminal is handing over to the synchronous network 120 (S212).

If the WCDMA mobile switching station 113 determines that the SMS destination terminal is being handed over to the synchronous network 120, the WCDMA mobile switching station 113 converts the received GSM-MAP type short message into an IS-41 MAP type short message (S214). . Here, the IS-41 MAP type short message is a short message encoded in the IS-637 format of the synchronous network 120.

The WCDMA mobile switching center 113 routes the CDMA 2000 mobile switching center 123 to transmit the converted IS-41 MAP type short message (S216).

The WCDMA mobile switching center 113 transmits the IS-41 MAP type short message to the routed CDMA 2000 mobile switching center 123 (S218). The SMS destination terminal receives the IS-41 MAP type short message through the CDMA 2000 mobile switching center 123, the CDMA 2000 BSC 122, and the CDMA 2000 BTS 121 (S220).

On the other hand, if the WCDMA mobile switching station 113 determines that the SMS terminating terminal is not being handed over to the synchronous network 120 as a result of the determination in step S212, the WCDMA mobile switching center 113 processes the short message according to a short message processing routine in a typical WCDMA network. (S222).

3 is a flowchart illustrating a process of providing an incoming service for transmitting a short message from the asynchronous network 110 to the mobile communication terminal 100 handing over to the synchronous network 120 according to the second embodiment of the present invention.

The incoming service of the short message according to the second embodiment of the present invention shown in FIG. 3 is similar to the incoming service of the short message according to the first embodiment of the present invention described with reference to FIG.

However, the short message to be transmitted from the asynchronous network 110 to the SMS destination terminal handing over to the synchronous network 120 is transmitted to the WCDMA packet switching support node 115 through the short message center 114 (S310). Upon receiving the short message, the packet-switching support node 115 determines whether the SMS destination terminal is being handed over to the synchronous network 120 (S312).

The WCDMA packet switching support node 115 converts the received GSM-MAP type short message into an IS-41 MAP type short message when it is determined in step S212 that the SMS destination terminal is being handed over to the synchronous network 120 ( S314). Thereafter, the WCDMA packet-switching support node 115 transmits the converted IS-41 MAP type short message to the WCDMA mobile switching station 113 (S316).

Since steps S318 to S324 are the same as steps S216 to S222 described with reference to FIG. 2, a detailed description thereof will be omitted.

4 is a flowchart illustrating a short message processing procedure transmitted from a mobile communication terminal 100 that performs a handover from an asynchronous network 110 to a synchronous network 120 according to a third embodiment of the present invention.

The short message sent from the mobile communication terminal 100 handed over from the asynchronous network 110 to the synchronous network 120 is transmitted to the CDMA 2000 mobile switching center 123 via the CDMA 2000 BTS 121 and the CDMA 2000 BSC 122. It is transmitted (S410). Upon receiving the short message, the CDMA 2000 mobile switching center 123 determines whether the originating mobile communication terminal 100 is being handed over (S412).

If it is determined in step S412 that the originating mobile communication terminal 100 is in the handover state, the short message is transmitted to the WCDMA mobile switching center 113 (S414). The WCDMA mobile switching center 113 receives the short message transmitted from the CDMA 2000 mobile switching center 123, and converts the received short message into an asynchronous short message using an asynchronous SMS protocol (S416).

The WCDMA mobile switching center 113 transmits the converted asynchronous short message to the short message center 114 (S418). Upon receiving the asynchronous short message, the short message center 114 transmits the short message to the SMS receiver (S420).

On the other hand, if the CDMA 2000 mobile switching center 123 determines that the mobile communication terminal 100 is not in a handover as a result of the determination in step S412, the CDMA 2000 mobile switching center 123 processes the short message according to the short message processing routine in the conventional CDMA 2000 network (S422). .

FIG. 5 is a flowchart illustrating a short message processing procedure transmitted from a mobile communication terminal 100 handing over from an asynchronous network 110 to a synchronous network 120 according to a fourth embodiment of the present invention.

The outgoing service of the short message according to the fourth embodiment of the present invention shown in FIG. 5 is similar to the outgoing service of the short message according to the third embodiment of the present invention described with reference to FIG. 4.

However, when the short message is transmitted from the CDMA 2000 mobile switching center 123 to the WCDMA mobile switching station 113, the WCDMA mobile switching station 113 transmits the short message to the WCDMA packet switching support node 115 without modification. (S516). Upon receiving the short message, the WCDMA packet exchange support node 115 converts the received short message into an asynchronous short message using an asynchronous SMS protocol or the like (S518). The WCDMA packet exchange support node 115 transmits the converted asynchronous short message to the short message center 114 (S418).

Since steps S522 to S524 are the same as steps S420 to S422 described with reference to FIG. 4, a detailed description thereof will be omitted.

The above description is merely illustrative of the present invention, and those skilled in the art will appreciate that various modifications can be made without departing from the essential features of the present invention. Accordingly, the embodiments disclosed herein are not intended to limit the present invention but to describe the present invention, and the spirit and scope of the present invention are not limited by these embodiments. It is intended that the scope of the invention be interpreted by the following claims, and that all descriptions within the scope equivalent thereto shall be construed as being included in the scope of the present invention.

As described above, the conventional mobile communication system has a disadvantage that the incoming or outgoing service of the short message is performed only after the end of the call of the mobile communication terminal for the mobile communication terminal handover from the asynchronous network to the synchronous network, according to the present invention Since the mobile terminal is processed in real time at the same time as the service request during the handover of the mobile terminal has the advantage that it is possible to quickly receive or send a short message.
