1 is a schematic diagram of a message service providing system 100 according to an embodiment of the present invention.

Referring to FIG. 1, a message service providing system 100 according to an embodiment of the present invention provides a message service allowing a service message transmitted from a caller terminal 10 to be received at a receiver terminal 20 And includes a location registration server 110, a source-side switching device 120, a message server 130, and a receiving-side switching device 130, and the like.

1, the location registration server 110 receives the location registration request message transmitted from the recipient terminal 20 through the recipient exchange device 140 and transmits the location registration request message to the recipient exchange device 140 Can be registered and managed as the location of the receiver terminal. The caller-side switching device 120 receives the service message transmitted from the caller terminal 10 and transmits the received service message to the message server 130. The message server 130 stores the type and address information of the receiving-side exchange device 140 connected to the recipient terminal 20 corresponding to the recipient information indicated in the service message received from the source-side switching device 120, Server 110, and delivers the service message to the confirmed address information. The recipient exchange apparatus 140 receives the service message from the message server 130 and transmits the service message delivered from the message server 130 to the recipient terminal 20 through the paging process to the recipient terminal 20, .

Here, the originator terminal 10 and the recipient terminal 20 may be terminals connected to the same service network or terminals connected to other service networks. That is, for example, each of the originator terminal 10 and the recipient terminal 20 may be a first terminal type connected to the LTE network or a second terminal type connected to another communication network different from the LTE network.

In this connection, in the case where the calling terminal 10 is the first terminal type connected to the LTE network, the calling side switching apparatus 120 connected to the calling terminal 10 transmits the "MME: Mobility " Management Entity ". When the calling terminal 10 is a second terminal type connected to another communication network (for example, a WCDMA network, etc.) different from the LTE network, the calling side switching apparatus 120 connected to the calling terminal 10 connects with 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 the "mobile management entity" of the LTE network. And may be a "mobile switching device" of another communication network that is different from the LTE network if the recipient terminal 20 is a second terminal type connected to another communication network that is different from the LTE network. The type of the receiving-side switching device 140 means that the receiving-side switching device 140 is a switching device included in any communication network. The type of the receiving-side switching device 140 is a mobile management entity and a mobile switching device.

First, the message service providing system 100 must know where the recipient terminal 20 is located in order to service the service message created by the originator terminal 10 to the recipient terminal 20. To this end, the location registration server 110 included in the message service providing system 100 receives a location registration request from all subscriber terminals (including both the originator terminal 10 and the receiver terminal 20) And performs a location registration procedure for registering the location of the subscriber terminal. At this time, the location of the subscriber terminal is registered and stored as the address information of the switching device (MME or MSC) connected to the subscriber terminal (see Fig. 4).

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

When the receiver terminal 20 is the first terminal type connected to the LTE network, the location registration server 110 transmits the location registration request message transmitted from the receiver terminal 20 to the mobile management entity (Such as an IP address) of the mobile management entity (MME), which is the receiving-side switching device 140, as the location of the recipient terminal 20. [

When the receiver terminal 20 is a second terminal type connected to another communication network such as a WCDMA network which is separated from the LTE network, the location registration server 110 transmits the location registration request message transmitted from the receiver terminal 20 to the receiver side (MSC), which is the exchange apparatus 140, and registers the address information of the mobile switching center (MSC), which is the receiving-side exchange apparatus 140, as the location of the recipient terminal 20. [

Of course, the location registration server 110 can also perform the location registration procedure in the same manner as the location registration procedure of the receiver terminal 20, with respect to the caller terminal 10 as well. The originator terminal 10 and the recipient terminal 20 are terminals classified according to the origination and reception of the service message and the originator terminal 10 may be the recipient terminal in other situations.

According to the location registration procedure described above, the location registration server 110 registers and stores the location of all the subscriber terminals (which may include both the calling terminal 10 and the receiving terminal 20) receiving the message service The message service providing system 100 performs a procedure of transmitting a service message to the recipient terminal 20 when the sender terminal 10 creates a service message and sends the message to the recipient terminal 20. In this case, The service message transmission procedure will be described according to the types of the caller terminal 10 and the receiver terminal 20, respectively.

First, when 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 receiver side exchange device 140 connected to the receiver terminal 20 is the mobile management entity MME ), The message server 130 receives the service message from the mobile management entity (MME), which is the calling side switching apparatus 120 connected to the calling terminal 10, and stores the received service message in the received service information The location registration server 110 confirms the address information of the mobile management entity (MME), which is the receiving-side exchange apparatus 140 connected to the corresponding recipient terminal 20, through the location registration server 110, (MME), which is the mobile management entity (MME). Accordingly, the mobile management entity (MME) as the receiving-side switching device 140 receives the service message from the message server 130 and transmits the service message to the message server 130 And transmits the service message to the corresponding recipient terminal 20.

Next, when the calling terminal 10 is the first terminal type LTE terminal connected to the LTE network and the receiving terminal 20 is the terminal of the second terminal type connected to another communication network separated from the LTE network (e.g., WCDMA When the recipient terminal 20 connected to the recipient exchange apparatus 140 is a mobile exchange apparatus (MSC), the message server 130 transmits the message to the sender terminal 10, And receives the service message from the mobile management entity (MME) 120 as the device 120 and transmits the service message to the mobile switching device 140 (the receiving side switching device 140) connected to the recipient terminal 20 corresponding to the recipient information indicated in the received service message MSC through the location registration server 110 and transmits the service message to the MSC, which is the receiving-side switching device 140 corresponding to the address information of the confirmed MSC do. Accordingly, the MSC, which is the receiving-side switching device 140, receives the service message from the message server 130 and transmits the service message to the message server 130 To the recipient terminal 20.

It is also possible that the caller terminal 10 is a second terminal type terminal (e.g., a WCDMA terminal) connected to another communication network that is different from the LTE network and the receiver terminal 20 is a terminal of the first terminal type connected to the LTE network The message server 130 determines that the caller terminal 10 is connected to the calling side switching apparatus 120 (120) in the case where the receiving side switching apparatus 140 connected to the receiving terminal 20 is the mobile management entity (MME) (MME), which is the receiving-side switching device 140 connected to the receiving terminal 20 corresponding to the receiving-side information indicated in the service message, from the mobile switching center (MSC) 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 confirmed mobile management entity (MME). Accordingly, the mobile management entity (MME) as the receiving-side switching device 140 receives the service message from the message server 130 and transmits the service message to the message server 130 To the recipient terminal 20.

According to one embodiment of the present invention, when the message server 130 delivers a service message to the recipient exchange 140, which is a mobility management entity, It is possible to solve the call processing delay problem that occurs by transferring the service message to the receiving-side switching device 140 which is the mobile management entity via the MSC.

Hereinafter, the message server 130 and the message service providing method provided by the message service providing system 100 will be described in detail with reference to FIGS. 2 and 3. FIG.

Fig.

The above-mentioned "other communication network different from the LTE network" can be any communication network other than the LTE network, but will be described below as a WCDMA network for convenience of explanation. Accordingly, 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 order to illustrate call processing for a location registration procedure and a message origination / termination procedure. 5, each of the caller terminal 10 and the receiver terminal 20 is an LTE terminal (the first LTE terminal 511, the 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.

[0060]

It is also assumed that the location registration server 110 is an HSS / HLR (Home Subscriber Server / Home Location Register) 510 and the message server 130 is an SMSC (Short Message Service Center) 530.

In this situation, the first LTE terminal 511, which may be the originator terminal 10 or the recipient terminal 20, and the WCDMA terminal 513 are registered in 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.

The first LTE terminal 511 transmits 'Enhanced Packet Core' / International Mobile Subscriber Identity) to the eNB, and the eNB forwards the received "Attach Request" to the first MME 521. Then, the first MME 521 transmits a location update request message " Update Location Request "to the HSS / HLR 510. At this time, the address information (IP address) of the first MME 521 is" May be included.

The process up to this point is the process defined in the Circuit Switching (CS) Fallback procedure. The CS Fallback process is a standard defined in order for a terminal receiving a service in an LTE network to receive voice service through a communication network (eg, a WCDMA network) different from the LTE network.

5 to 10, the HSS (Home Subscriber Server) and the HLR (Home Location Register) are integrated and represented as HSS / HLR (Home Subscriber Server / Home Location Register) In this case, the HSS transmits the MME information to the HLR, and the HLR can manage the address information (IP address) of the MME for the corresponding terminal. Alternatively, the MME may pass an "Update Location Request" directly to the HLR.
