The calling party switching device 120 receives the service message transmitted from the calling party terminal 10 and transmits it to the message server 130. The message server 130 registers the location and the type of address and the address information of the receiving side switching device 140 connected to the recipient terminal 20 corresponding to the recipient information indicated in the service message received from the calling side switching device 120. Check through the server 110, and delivers the service message to the confirmed address information. The receiving exchange device 140 receives the service message from the message server 130 and receives the service message transmitted from the message server 130 through paging to the receiver terminal 20. To send.

Here, the sender terminal 10 and the receiver terminal 20 may be a terminal connected to the same service network or a terminal connected to another service network. That is, for example, each of the sender terminal 10 and the receiver terminal 20 may be a first terminal type connected to the LTE network or a second terminal type connected to another communication network that is distinct from the LTE network.

In this regard, when the caller terminal 10 is the first terminal type connected to the LTE network, the caller side exchange apparatus 120 connected to the caller terminal 10 may be referred to as a "mobile management entity (MME: Mobility)" of the LTE network. Management Entity) ". When the caller terminal 10 is a second terminal type connected to another communication network (eg, WCDMA network, etc.) that is distinct from the LTE network, the caller switching device 120 connected by the caller terminal 10 may be connected to the LTE network. May be a "Mobile Switching Center (MSC)" of another communication network.

In addition, when the receiver terminal 20 is the first terminal type connected to the LTE network, the receiver side exchange apparatus 140 connected to the receiver terminal 20 may be a "mobile management entity" of the LTE network. When the receiver terminal 20 is a second terminal type connected to another communication network different from the LTE network, the receiver terminal 20 may be a "mobile switching device" of another communication network different from the LTE network. The type of the receiving side switching device 140 refers to which communication network the receiving side switching device 140 is included in, and the mobile management entity and the mobile switching device are types.

First, the message service providing system 100 should know where the receiver terminal 20 is located in order to service the service message created in the sender terminal 10 to the corresponding receiver terminal 20. To this end, the location registration server 110 included in the message service providing system 100 requests a location registration from all subscriber stations (including both the sender terminal 10 and the receiver terminal 20) receiving the message service. A location registration procedure for receiving a message and registering a location of a corresponding subscriber station is performed. At this time, the location of the subscriber station is registered and stored as address information of the switching device (MME or MSC) to which the subscriber station is connected (see FIG. 4).

The location registration procedure performed by the location registration server 110 described above will be described below as a location registration procedure for the receiver terminal 20.

When the receiver terminal 20 is the first terminal type connected to the LTE network, the location registration server 110 may transmit the location registration request message transmitted from the receiver terminal 20, which is the receiving side switching device 140, to the mobile management entity. Received from the MME, the address information (for example, IP address, etc.) of the mobile management entity (MME), which is the receiving side switching device 140, is registered as the location of the receiver terminal 20.

If the receiver terminal 20 is a second terminal type connected to another communication network such as a WCDMA network that is distinct from the LTE network, the location registration server 110 receives the location registration request message transmitted from the receiver terminal 20. It receives from the mobile switching device (MSC) which is the switching device 140, and registers the address information of the mobile switching device (MSC) which is the receiving side switching device 140 as the position of the receiver terminal 20.

Of course, also for the caller terminal 10, the location registration server 110 may perform a location registration procedure in the same manner as the above-described location registration procedure of the receiver terminal 20. The sender terminal 10 and the receiver terminal 20 are only terminals classified according to the transmission and reception of the service message, and may be the receiver terminal in different situations.

According to the above location registration procedure, the location registration server 110 registers and stores locations for all subscriber terminals (which may include both the sender terminal 10 and the receiver terminal 20) that receive the message service. In the state, when the caller terminal 10 composes a service message and sends it toward the receiver terminal 20, the message service providing system 100 performs a procedure of transmitting a service message to the receiver terminal 20. The service message transmission procedure will be described according to the type of each of the sender terminal 10 and the receiver terminal 20.

First, both the sender terminal 10 and the receiver terminal 20 are LTE terminals of the first terminal type connected to the LTE network, and the receiving side switching device 140 connected to the receiver terminal 20 is a mobile management entity (MME). ), The message server 130 receives the service message from the mobile management entity (MME), which is the calling party switching device 120 to which the calling party terminal 10 is connected, and transmits the message to the receiver information indicated in the received service message.

Next, the caller terminal 10 is an LTE terminal of the first terminal type connected to the LTE network, and the second terminal type terminal (eg, WCDMA) in which the receiver terminal 20 connects to another communication network separated from the LTE network. Terminal), and the message server 130 connects to the calling party terminal 10 to which the calling party terminal 10 is connected. A mobile switching device that is a receiving side switching device 140 that receives a service message from a mobile management entity (MME), which is the device 120, and is connected to a receiver terminal 20 corresponding to the receiver information indicated in the received service message ( Checking the address information of the MSC through the location registration server 110, and delivers the service message to the mobile switching device (MSC), which is the receiving side switching device 140 corresponding to the confirmed MSC address information. do. Accordingly, the MSC, which is the receiving side exchange device 140, receives the service message from the message server 130 and performs a paging process to the receiver terminal 20, which is the second terminal type, through the message server 130. Transmits the service message delivered from the < RTI ID = 0.0 >

In addition, the caller terminal 10 is a terminal of a second terminal type (for example, a WCDMA terminal) connected to another communication network distinct from the LTE network, and the receiver terminal 20 of the first terminal type connected to the LTE network. In the case where the receiving terminal exchange device 140 connected to the receiver terminal 20 is an LTE management device and thus a mobile management entity (MME), the message server 130 indicates that the sender terminal 10 is the calling terminal switching device 120. Address information of a mobile management entity (MME), which is a receiving side switching device 140 which receives a service message from a mobile switching device (MSC), and is connected to a receiver terminal 20 corresponding to the receiver information indicated in the service message. , Through the location registration server 110, and delivers the service message to the mobile management entity (MME), which is the receiving side switching device 140 corresponding to the address information of the mobile management entity (MME). Accordingly, the mobile management entity (MME), which is the receiving side switching device 140, receives the service message from the message server 130 and performs a paging process to the receiver terminal 20 of the first terminal type. Transmits the service message delivered from the < RTI ID = 0.0 >

According to an embodiment of the present invention, when the message server 130 delivers the service message to the receiving side exchange device 140, which is the mobile management entity, the message server 130 transfers the message directly without passing through other devices. It is possible to solve the call processing delay problem caused by passing the service message to the receiving side exchange device 140, which is a mobile management entity, via the device MSC.

Referring to FIG. 3, in the message service providing method according to an embodiment of the present invention, the location registration server 110 receives a location registration request message transmitted from the receiver terminal 20, and the receiver terminal 20 receives the message. Location registration step (S300) for registering the address information of the connected receiving side switching device 140 as the location of the receiver terminal 20, and the message server 130 transmits the service message transmitted from the caller terminal (10). Service message transmission step (S302) received through the exchange device 120, and the message server 130 of the receiving side exchange device 140 connected to the receiver terminal 20 corresponding to the recipient information indicated in the service message Recipient location checking step (S304) of confirming the address information through the location registration server 110, and the message server 130 delivers the service message to the receiving side switching device 140 corresponding to the confirmed address information, the service Forward the message The receiving side exchange device 140 receives the service message receiving step (S306), etc. for transmitting the service message to the receiver terminal 20 through the paging process to the receiver terminal 20.

As described above, the sender terminal 10 and the receiver terminal 20 are MSCs of other communication networks separated from the terminal type (first terminal type, second terminal type) and network access location (MME of LTE network, LTE network). ), The message service providing system 100 according to an embodiment of the present invention, the message service (from the caller terminal 10 connected to the LTE network to the receiver terminal 20 connected to the LTE network ( Type 1), a message service (type 2) from the caller terminal 10 connected to the LTE network to the receiver terminal 20 connected to another communication network distinct from the LTE network, and another communication network distinct from the LTE network. The message service (type 3) from the connected caller terminal 10 to the receiver terminal 20 connected to the LTE network and the caller terminal 10 connected to another communication network distinct from the LTE network are distinguished from the LTE network. To the receiver terminal 20 connected to another communication network. Four types of message services can be provided, including message services (type 4).

In particular, below, a call processing procedure (message origination) for providing a message service (type 1, type 2 and type 3) when at least one of the caller terminal 10 and the receiver terminal 20 is connected to the LTE network. / Call processing procedure for incoming and location registration) is exemplarily described with reference to FIGS.

The above-mentioned "other communication network distinguished from LTE network" may be any communication network other than the LTE network, but will be described below as a WCDMA network for convenience of description. Accordingly, in order to exemplarily describe call processing for a location registration procedure and a message origination / reception procedure, it is assumed that a message service providing system 100 according to an embodiment of the present invention is constructed as shown in FIG. 5. In FIG. 5, each of the caller terminal 10 and the receiver terminal 20 is the "LTE terminal (first LTE terminal 511, second LTE terminal 512)" of the first terminal type connected to the LTE network. , "WCDMA terminal 513" of the second terminal type connected to the WCDMA network. In addition, each of the calling side switching device 120 and the receiving side switching device 140 is a switching device to which the calling terminal 10 or the called terminal 20 is connected, and includes a first MME 521 and a second MME 522. ) And MSC 523.

In addition, it is assumed that the location registration server 110 is a home subscriber server / home location register (HSS / HLR) 510, and the message server 130 is a short message service center (SMSC) 530.

In this situation, the first LTE terminal 511 and the WCDMA terminal 513, which may be the caller terminal 10 or the receiver terminal 20, register the location with the HSS / HLR 510 which is the location registration server 110. The processing procedure will be described with reference to FIGS. 6 and 7, respectively.

FIG. 6 shows a first MME in which a first LTE terminal 511, which is one of the LTE terminals which may be the calling terminal 10 or the receiving terminal 20, is its switching device (calling side switching device or receiving side switching device). A call processing procedure for registering a location to the HSS / HLR 510 through 521 is illustrated.

Referring to FIG. 6, the first LTE terminal 511 transmits a location registration request message “Attach Request” to the first MME 521, which is its switching device, to start a call processing procedure for location registration. . At this time, the first LTE terminal 511 is connected to the first MME 521 through an eNB (Enhanced Node B) eNB, the first LTE terminal 511 'Attach Type' is EPS / IMSI (Enhanced Packet Core) / Attach Request "designated as an International Mobile Subscriber Identity) is transmitted to the eNB, and the eNB transmits the received" Attach Request "to the first MME 521. Thereafter, the first MME 521 transmits a location update request message “Update Location Request” to the HSS / HLR 510, and at this time, the “Update Location Request” includes address information (IP address) of the first MME 521. May be included. Thereafter, the HSS / HLR 510 receives the “Update Location Request”, stores the address information (IP address) of the first MME 521, and transmits the “Update Location Response” to the first MME 521. The first MME 521 may send an “Attach Response” to the first LTE terminal 511. Here, although not shown in the drawing, the first MME 521 receives the "Update Location Response" from the HSS / HLR 510 and then sends a "Location Update Request" to the HSS / HLR 510 through the MSC. After the location registration is performed by the HSS / HLR 510, the "Location Update Reponse" may be transmitted to the MSC. The process so far is defined in the CS (Circuit Switching) Fallback procedure. The CS fallback process is a standard defined for a terminal receiving a service in an LTE network to receive a voice service through a communication network different from the LTE network (for example, a WCDMA network).

Meanwhile, in FIGS. 5 to 10, a home subscriber server (HSS) and a home location register (HLR) are integrated, and are represented as a home subscriber server / home location register (HSS / HLR), but are not integrated. In this case, the HSS transmits MME information to the HLR, and the HLR may manage address information (IP address) of the MME for the corresponding terminal. Alternatively, the MME may send an "Update Location Request" directly to the HLR.

In FIG. 6, a call processing procedure for location registration of a first LTE terminal 511, which is an LTE terminal, is illustrated and described, but a call processing procedure for location registration of a WCDMA terminal 513 may be similarly performed. According to a call processing procedure for location registration of the WCDMA terminal 513, the HSS / HLR 510 stores address information of the MSC 523 to which the WCDMA terminal 513 is connected.

When the CS fallback mode is performed through the call processing procedure for location registration described above, a state in which a message can be transmitted through an LTE network is obtained. Therefore, below, call processing for message origination / reception to provide a message service according to the types of the sender terminal 10 and the receiver terminal 20 will be described with reference to FIGS. 7 to 9.

7 is a view illustrating a message service type from a first LTE terminal 511 to a second LTE terminal 512 in the environment illustrated in FIG. 5 in order to apply a message service providing method according to an embodiment of the present invention. A diagram showing a call processing procedure.

Referring to FIG. 7, the first LTE terminal 511 serving as the calling party terminal 10 services the first MME 521 serving as the calling side switching device 120 connected with itself to transmit a service message in the CS fallback mode. When sending an "Uplink Non Access Stratum (NAS) Transport" containing a message, the first MME 521 sends a service message to the corresponding message server SMSC 530 according to the predefined IP address of the SMSC 530. Send the included "Uplink Unidata". At this time, the SGs AP protocol may be used to deliver "Uplink Unidata". Thereafter, the SMSC 530 confirms the address information of the receiving side exchange apparatus 140 as the "Routing Information" through the HSS / HLR 510 as the location of the receiver terminal 20 corresponding to the receiver information indicated in the service message. In this case, the receiver terminal 20 recognizes that the address information of the receiving side switching device 140 is the address information (IP address) of the second MME 522. 2 LTE terminal 512 can be seen. The SMSC 530 transmits the "Downlink Unidata" including the service message to the second MME 522 by using the verified address information (IP address) of the second MME 522 which is the receiving side exchange device 140. .

Thereafter, the SMSC 530 confirms the address information of the receiving side exchange apparatus 140 as the "Routing Information" through the HSS / HLR 510 as the location of the receiver terminal 20 corresponding to the receiver information indicated in the service message. In this case, the WCDMA of the second terminal type in which the receiver terminal 20 accesses the WCMDA network separated from the LTE network by recognizing that the confirmed address information of the receiving side switching device 140 is the address information of the MSC 523. It can be seen that the terminal 513. The SMSC 530 transmits the "MT Forward Short SM" including the service message to the MSC 523 by using the confirmed address information of the MSC 523 which is the receiving side exchange device 140. The MSC 523 attempts to page to the WCDMA terminal 513, which is the receiver terminal 20, and when the WCDMA terminal 513 completes radio resource setting through "Service Request" in response to paging, a service message is included.
