In the embodiment of the present invention, the HLR 400 searches whether the subscriber of the mobile terminal 100 that has requested a message search is subscribed to the message search service and provides the result.

The SMSC 500 processes a basic service for SMS, and temporarily stores or delivers data for processing a short message. In addition, it performs a gate function for a short service, performs a short service MAP (Mobile Application Part) processing function for interworking with the exchange 300 and the HLR 400, and protocol matching for interworking with an external service provider. It also functions.

In particular, the SMSC 500 according to the embodiment of the present invention receives an SMSPP (SMS Delivery Point to Point) message from the exchange 300, and the received message requests a search for a message stored in the message server 600. Determine the cognition. At this time, if it is determined that the received message is a message requesting a message search, the SMSC 500 transmits the received message to the message server 600. Here, the SMSC 500 inquires whether the subscriber of the mobile terminal 100 is subscribed to the message retrieval service or not, and the message is received as described above only when the subscriber is subscribed to the message retrieval service. To the message server 600. In addition, the SMSC 500 requests the message search when the called number transmitted from the mobile terminal 100 and included in the SMDPP message received from the exchange 300 is a predetermined reception number, a special character, or a special string. Judging by the message. In this case, the specific reception number is a reception number that is set to know that the message is requested to search for a message in advance, and special characters or special strings include, for example, "*", "#", "**", and "**". # "And the like. When the short message retrieved by the message server 600 is delivered from the message server 600, the SMSC 500 transmits the short message to the mobile terminal 100.

The message server 600 searches for the short messages stored according to the search condition included in the search request message transmitted from the SMSC 500, and if the short message is found, the short message is sent to the SMSC 500. Transfer and retransmit to the mobile terminal 100. At this time, the message server 600 redisplays the calling number of the calling terminal that transmitted the searched short message and retransmits the short message to the mobile terminal 100.

FIG. 2 is a detailed block diagram of the message server 600 shown in FIG. 1.

As shown in FIG. 2, the message server 600 includes a message storage unit 610, a receiver 620, a search unit 630, and a transmitter 630.

The message storage unit 610 stores the short message received using the mobile terminal 100 as the called number.

The receiving unit 620 receives the message transmitted from the SMSC 500, extracts the calling number and the search condition which are the phone numbers of the mobile terminal 100 from the received message, and delivers the message to the search unit 630 to request the message search. do.

The search unit 630 receives the calling number and the search condition transmitted from the receiving unit 620, and stores the short message stored in the message storage unit 610 according to the search condition for the short message received and stored using the calling number as the called number. After performing a search for the user, if the short message is found, the searched short message is transmitted to the calling unit 640. Here, the search conditions for the search unit 630 to perform the search may include a text content search condition for searching for a specific content included in the content of the short message, a call number search condition for the calling subscriber who transmitted the short message. In addition, since the content content search condition is the same as the method of performing a content search in a general search system, a detailed description thereof will be omitted. For example, when the destination number of the message delivered from the exchange 300 is a special string "**" which is set in advance, and the body content of the message is "Dokdo * Japan", the SMSC 500 corresponds to the corresponding message. The message is determined to be a message search request message and transmitted to the message server 600. The search unit 630 of the message server 600 determines the search condition as the text content search condition, and stores the text among the stored short messages. A short message containing both words of "Dokdo" and "Japan" is searched for in the contents, and if the short message is found, the short message is transmitted to the sender 640. At this time, the retrieval unit 630 also transmits the calling party's calling number that transmitted the retrieved short message to the calling unit 640. In addition, even if there are two or more searched short messages, the search unit 630 transfers all of the searched short messages to the transmitter 640.

The transmitter 640 transmits the short message transmitted from the search unit 630 to the SMSC 500 to transmit the short message as a search result of the short message requested by the mobile terminal 100. At this time, the calling unit 640 writes the calling number delivered together from the searching unit 630 in the calling number of the short message delivered to the SMSC 500, and the called number of the mobile terminal 100 requesting the message search. Forward the phone number. In addition, when the sender 640 has two or more short messages searched and delivered by the searcher 630, the SMSC 500 performs a message conversion process of merging the searched short messages into one short message. To pass. Such a message conversion process is well known in the art, since it is well known to those skilled in the art that the sender 640 can be easily performed by processing the data of the short messages. Omit. Here, even when there are two or more searched short messages, the calling unit 640 writes the telephone number of the mobile terminal 100 which requested the message search in the called number of the short message which is merged and becomes one. However, in the case of the caller number of the merged short message, the caller numbers of the two or more short messages retrieved may be different from each other, and thus may be described in various ways. For example, the caller number of the short message located in front of the short message merged into one is written as the caller number of the short message which is converted into one, and the caller numbers of the remaining short messages are merged with each other. It can be written as a calling number immediately before or immediately after being placed in a single short message.

FIG. 3 is a diagram illustrating an example of a structure of the message storage unit 610 shown in FIG. 2.

As shown in FIG. 3, the message storage unit 610 includes a called number field 610a, a calling number field 610b, and a message data field 610c.

The called number field 610a stores the telephone number of the called mobile terminal which has received the short message stored in the message storage 610.

The call number field 610b stores the phone number of the calling mobile terminal which has transmitted the short message stored in the message storage 610.

The message data 610c stores the body content of the short message stored in the message storage 610.

If the message storage unit 610 needs to store other information in addition to the above fields, a corresponding storage field may be added.

Hereinafter, a method of providing a message retrieval service according to an embodiment of the present invention will be described with reference to FIG. 4.

As described above, a plurality of short messages received by the called mobile terminal are stored in the message storage unit 610 of the message server 600. Of course, the short messages received by the mobile terminal 100 requesting the message search according to the embodiment of the present invention are also stored.

First, in order to search for a specific short message among the short messages received by the user of the mobile terminal 100, the called number is described as a predetermined specific reception number, a special character or a special string, and then the search condition is described. The short message described above is transmitted through the mobile terminal 100 (S101).

The exchange 300 of the mobile communication system receives the short message transmitted from the mobile terminal 100 through the base station 200, and then processes the SMDPP message corresponding to the short message by SMSC (processing). 500) (S103).

After receiving the SMDPP message transmitted from the exchange 300, the SMSC 500 recognizes that the called number included in the SMDPP is a preset specific reception number, a special character, or a special character string, and then retrieves the message from the mobile terminal 100. After confirming that the request, the query to the HLR (400) whether the subscriber of the mobile terminal 100 requesting the message search is subscribed to the message search service (S105).

Next, the HLR 400 checks whether the subscriber of the mobile terminal 100 is subscribed to the message search service and transmits the result to the SMSC 500 (S107). Here, it is assumed that the subscriber of the mobile terminal 100 is subscribed to the message search service.

If it is confirmed from the HLR 400 that the subscriber of the mobile terminal 100 is subscribed to the message retrieval service, the SMSC 500 delivers the short message transmitted from the mobile terminal 100 to the message server 600 to retrieve the message. Request (S109).

The message server 600 searches for the short messages stored in the message server 600 using the telephone number of the mobile terminal 100 as the called number according to a search condition included in the short message transmitted from the SMSC 500. The short message matching the search condition is found (S111).

If there is a short message found in the search step S111, the message server 600 transmits the searched short message to the SMSC 500 (S113 to S119).

The steps S111 to S119 will be described in more detail.

When the receiving unit 620 of the message server 600 receives the short message from the SMSC 500, the search unit 630 after extracting the calling number that transmitted the short message and the search condition included in the body content of the short message. To pass).

Thereafter, the searching unit 630 compares the called number stored in the called number field 610a of the message storage unit 610 with the called number delivered from the receiving unit 620 as the called number. Also, according to a search condition transmitted from the receiving unit 620, after searching the source number field 610b or the message data field 610c of the short message of the target to search for short messages that match the search condition, the searched If there is a short message, the searched short message is transmitted to the sender 640 (S111). Next, the transmitter 640 checks whether there is a searched short message (S113). If there is no searched short message, the message search service is terminated. If there is a searched short message, it is checked whether there is one searched short message (S117). If the retrieved short message is not one but two or more, the sender 640 merges the two or more short messages into one short message (S117). Thereafter, the transmitter 640 transmits one short message to the SMSC 500 to transmit the short message as a search result of the short message requested by the mobile terminal 100 (S119). At this time, the calling unit 640 writes the calling number delivered together from the searching unit 630 in the calling number of the short message delivered to the SMSC 500, and the called number of the mobile terminal 100 requesting the message search. Forward the phone number. However, if there are two or more retrieved short messages, the calling number and the called number of the short message merged into one as described above are described.

Next, the SMSC 500 transmits the retrieved short message transmitted from the message server 600 to the exchange 300 as an SMDPP message to the mobile terminal 100 (S121).

The exchange 300 transmits a corresponding short message to the mobile terminal 100 according to the SMDPP message transmitted from the SMSC 500 (S123).

Accordingly, a user of the mobile terminal 100 may search for and re-receive a short message corresponding to a specific search condition among short messages received by the mobile terminal 100 and stored in the message server 600.

On the other hand, while the message server 600 has been described as performing a message search in response to a request from the SMSC 500, the technical scope of the present invention is not limited to this, by adding a search engine in the SMSC 500 The SMSC 500 may also perform a message search directly.
