The mobile communication terminal 100 receives a new message of SizeNew size (S310). Where SizeNew is the data size of the newly received message. In addition, the message is preferably a text message via SMS, a multimedia message through MMS, for example, a broadcast-type multimedia message, and may include all data received and stored in the mobile communication terminal 100 widely.

When a new message is received, first, the size of the received message is examined and compared with the capacity of the message storage unit 170 which is the entire message storage space to determine whether to store the message (S320). If it is determined that the size of the received message is larger than the storage capacity of the message storage unit 170, the received message is discarded because it cannot be stored (S325).

In addition, it is determined whether the size of the received message is smaller than the size of the remaining space in which the message is not stored among the capacity of the message storage unit 170 which is the entire message storage space (S330). If it is determined that the size of the received message is smaller than the size of the remaining space, the received message is stored in the message storage unit 170 without any determination (S390).

If it is determined that the size of the message received by the message data size checking unit 210 is greater than the size of the remaining space of the message storage unit 170 according to the size of the received message, the message to be deleted is initialized (S340). ). Here, the deletion target message list is a list of messages received by the user and not set as a protection message among the received messages.

If the received message cannot be stored in the message storage unit 170 even after deleting the deletion target message list, it is determined whether there is an unprotected message among the messages stored by the user among the messages stored in the message storage unit 170 ( S350). Here, the unprotected message is a message not set as a protected message by the user.

As a result of the determination, if there is an unprotected message among the messages confirmed by the user among the messages stored in the message storage unit 170, the oldest message is added to the deletion target message list (S360).

After adding the oldest message among the unacknowledged messages to the deletion target message list, it is determined whether the sum of the remaining space of the message storage unit 170 and the size of the messages in the deletion target message list is larger than the sizeNew of the received message. (S370).

As a result of the determination, if the size of the received message is small, the message added to the deletion target message list is deleted and the received message is stored in the message storage unit 170 (S380 and S390).

If it is determined that the size of the received message is still large, it is determined whether there are more unprotected messages among the messages stored by the user among the messages stored in the message storage unit 170. In addition to the deletion target message list, the oldest message is sequentially added to the deletion target message until the sum of the remaining space of the message storage unit 170 and the size of the messages in the deletion target message list is larger than SizeNew, the size of the received message. Repeat the process of adding.

If the size of the received message is still large and the unprotected message is not found among the messages stored in the message storage unit 170 by the user, the message is not included in the delete target message list. It is determined whether there is an unprotected message not confirmed by the user (S352).

As a result of the determination, if there is an unprotected message among the messages unconfirmed by the user among the messages stored in the message storage unit 170, the oldest message is added to the deletion target message list (S354).

After adding the oldest message among the unprotected messages which are not confirmed by the user among the stored messages to the deletion target message list, the sum of the remaining space of the message storage unit 170 and the size of the message in the deletion target message list is received. It is determined whether the size is larger than SizeNew (S370).

As a result of the determination, if the size of the received message is small, the message added to the deletion target message list is deleted and the received message is stored in the message storage unit 170 (S380 and S390).

In addition, as a result of the determination, if the size of the received message is still large, it is determined whether there are more unprotected messages among the messages stored in the message storage unit 170 that are not confirmed by the user. By adding a message to the delete target message list, the oldest message is sequentially deleted until the sum of the remaining space of the message storage unit 170 and the size of the messages in the delete target message list is larger than SizeNew, the size of the received message. Repeat the process of adding to the message.

If the size of the received message is still large and there are no unprotected messages among the messages stored in the message storage unit 170 that are not confirmed by the user anymore, the mobile communication terminal 100 The display unit 140 outputs a guide message saying that it is not possible to store a newly received message as protected messages, and discards the received message (S356 and S325).

As described above, the method of the present invention may be implemented as a program and stored in a recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.) in a computer-readable form.

As described above, according to the mobile communication terminal and the message storage management method for managing message storage according to the present invention, there is an effect of providing convenience to the user by automatically managing the memory capacity of the message storage box for storing messages. .

In addition, when the new message is received, the memory capacity of the message storage box can be efficiently managed according to the data capacity of the new message.

Although the above has been described with reference to a preferred embodiment of the present invention, those skilled in the art to which the present invention pertains without departing from the spirit and scope of the present invention as set forth in the claims below It will be appreciated that modifications and variations can be made.
