DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for receiving a message which can prevent loss of important messages when the capacity of a message memory is insufficient, and more particularly to a method and an apparatus suitable for a pager.

[0002]

2. Description of the Related Art In recent years, in an information message service of a pager whose message volume is increasing, a large capacity of a message memory of a terminal is required. However, an increase in the memory capacity may increase the cost of the terminal. Further, since not all information messages received by the user are necessary, a function of selecting messages is required. Therefore, there is a need for a method capable of reliably receiving necessary messages without increasing the memory capacity.

A conventional pager message receiving method for reliably receiving such a required message is disclosed, for example, in Japanese Patent Application Laid-Open No. 4-290016. This conventional pager message receiving method, the notification time, the notification time in the received message, when a specific code such as a protection code that inhibits only automatic deletion is detected, the message is stored in a format that is not automatically deleted, Even if a limited memory capacity is exhausted due to reception of another message, a message that needs to be left is surely received to prevent the message from being lost.

[0004]

The conventional message receiving method in the pager is performed as described above.
In order to prevent the loss of a message that is highly necessary under the condition of the detection of a notification time, a notification time, and a protection code that prohibits only automatic erasure in a received message, it is necessary to receive the protected message at the receiver side. There were issues that did not fully reflect the evaluation criteria for the importance of messages.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and an object of the present invention is to provide an evaluation criterion for the importance of a received message on the receiver side, and an address at which the received message is stored. Provided is a message receiving method and apparatus which can sufficiently reflect received messages to be protected by a keyword registered for each message, and can reliably receive necessary messages without increasing the memory capacity. It is in.

[0006]

A message receiving method according to the present invention comprises a keyword registration step of pre-registering a specific keyword for each address at which a received message is stored on a receiving side; And a keyword registered in the keyword registration step, and a keyword determination step of determining whether or not the same word as the keyword is included in the received message. When it is determined that the same word as the keyword registered in the keyword registration step is included, a received message differentiating step for identifying the corresponding received message as a received message not including the same word as the keyword. , The received message differentiation step A received message containing the same word as the keyword registered in the keyword registration step, and a received message not containing the same word as the keyword, which can be identified in the keyword registration step. It is characterized by the following.

[0007] A message receiving apparatus according to the present invention comprises: a keyword registering means for registering a specific keyword in advance on a receiving side for each address at which a received message is stored; a receiving means for receiving a message; Received, the received message is compared with the keyword registered by the keyword registration means, keyword determination means to determine whether the same word as the keyword is included in the received message,
When the keyword determining unit determines that the received message includes the same word as the keyword registered by the keyword registering unit, the corresponding received message is regarded as a received message not including the same word as the keyword. A storage unit for storing a received message that includes the same word as the keyword registered by the keyword registration unit and a received message that does not include the same word as the keyword. And

[0008] The message receiving method and apparatus of the present invention provide a method for identifying a specific keyword or a common keyword that both the receiving side and the specific transmitting side recognize in common.
The receiving side registers in advance for each address where the received message is stored, and upon receiving the message, checks the received message against the registered keyword, and the received message includes the same word as the keyword. The received message is identified as a received message that does not include the same word as the keyword, and is stored together with the received message that does not include the same word as the keyword. For the differentiation of the received message including the same word as the above, the evaluation criteria on the receiving side are sufficiently reflected in the importance of the received message.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below. The message receiving method and apparatus according to an embodiment of the present invention provide a method in which a user registers a specific keyword in a pager in advance, compares the received message with the keyword, and includes the same word as the keyword in the received message. Is to automatically protect the message and prevent loss of a necessary message due to message deletion when the free space in the message memory is exhausted.

FIG. 1 is a block diagram showing a configuration of a pager which is an apparatus to which the message receiving method according to the present embodiment is applied. The pager includes a radio signal processing unit (receiving unit) 1, a decoder unit (receiving unit) 2, an LCD (keyword registration unit) 3, an LCD driver 4, a control unit (keyword registration unit, keyword determination unit, storage unit, storage message). Erasing unit 5, keyword table 6, key input unit (keyword registration unit) 7, notification unit 8, IDROM
9, a ROM (receiving means) 10, a RAM (keyword registration means) 11, and the like.

The radio signal processing unit 1 receives a radio signal transmitted from a base station in accordance with the intermittent reception control signal input from the decoder unit 2, demodulates the signal, and outputs the demodulated signal to the decoder unit 2.

The decoder unit 2 determines whether or not the calling number of the calling signal input from the radio signal processing unit 1 matches its own identification number, and controls the message receiving process only when the calling number matches the identification number. 5 is output as an interrupt.

The LCD 3 displays a menu or the like for registering a received message and a keyword by an LCD driving signal output from the LCD driver 4.

The LCD driver 4 outputs an LCD drive signal according to the display control signal output from the control unit 5.

The control unit 5 controls each unit, stores the received message in the received message memory of the RAM 11, outputs a notification control signal to the notification unit 8, and notifies the user of the message reception by sound or vibration. is there.

The keyword table 6 has the configuration shown in FIG. 2, is stored in the RAM 11, can be created and referred to by the control unit 5, and stores word data input from the key input unit 7 by the user.

The key input unit 7 inputs operation information to be performed when a user registers a keyword into the control unit 5. The notification unit 8 drives a notification speaker or a vibration motor based on a notification control signal output from the decoder unit 2.

The ID ROM 9 registers its own identification number and device parameters. The ROM 10 stores a program for the control unit 5 to perform message reception processing, intermittent reception control, notification control, message display control, and the like. The RAM 11 forms a reception message memory in which the control unit 5 stores a reception message.

Next, the operation will be described. In the pager according to the present embodiment, control unit 5 collates the received message stored in RAM 11 with keyword table 6 registered by the user in advance, and determines whether or not the same word exists in the received message. If there is the same word, a protect flag is provided for the message to prevent the message from being deleted when the message memory becomes full. For this reason, first, the user inputs “K” to the keyword 6 b in FIG.
A keyword such as "EYWORD1" or "KEYWORD2" is input, and this keyword can be set for each address where the received message is stored or for all addresses (ALL), as indicated by reference numeral 6a.

FIG. 3 is a flowchart showing a message receiving operation of the pager according to the present embodiment in which such a keyword is set. Hereinafter, the message receiving operation will be described with reference to the flowchart shown in FIG. In the reception standby state shown in step S1, the presence / absence of message reception is determined in the reception presence / absence determination process in step S2. As a result, if no message has been received, the process returns to step S1 to wait for reception. If it is determined in step S2 that there is a received message, the process proceeds to step S3, where the received message is sequentially compared with a pre-registered keyword to determine whether the same word exists. Step S
If it is determined in step 3 that there is no identical word, the process proceeds to step S5 for checking the free space of the message memory. On the other hand, if the same word exists, the process proceeds to step S4 for adding a protect flag to the message.

In step S4, a protection flag is added to the message, and the process proceeds to step S5. If it is determined in step S5 that the free space of the message memory is large enough to store the received message, the process proceeds from step S5 to step S7, and the message is stored in step SS7. If there is not enough free space, the process proceeds to step S6 to delete the oldest message from the messages stored in the past, and secure a memory capacity sufficient to store the message received this time. In step S6, after securing the capacity, the process proceeds to step S7, where the message is stored.

FIG. 4 is an explanatory diagram showing the storage status of received messages in the message memory, and the numerals indicate the message storage order. Now, it is assumed that messages 1 to 12 are stored using the entire message memory capacity. Here, when a new message is received, the oldest message among the messages received in the past is deleted (here, message 1 is the oldest), but since the protect flag of message 1 is “1”, the message is deleted. No. 1 deletes the messages whose protect flags are not "1" from the oldest message out of the messages 2 to 12 without deleting them, and secures the memory capacity necessary to store the new messages.

As described above, according to the present embodiment, when a message received in the past is deleted due to lack of free space in the message memory, not only the priority of the message reception order but also the terminal side is determined in advance. Because the protection flag reflecting the user's intention can be added to the received message by the keyword set for each address where the received message is stored or for all addresses, the evaluation of the importance of the received message at the receiver side Criteria can be fully reflected in received messages protected by keywords set for each address where received messages are stored or for all addresses, enabling the loss of messages important to the user if the message memory capacity is insufficient. Can be prevented.

Also, the receiving side can add a priority to the received message by a receiving order and a protection flag and automatically protect the message, so that the user can check the message without frequently checking the message. Can easily and reliably protect messages with high priority.

Also, by matching keywords between the sender and the receiver in advance, it is possible to automatically protect a message of a specific sender, and thus an important message from a specific sender can be erroneously identified. Erasure can be reliably prevented.

Next, another embodiment of the present invention will be described. FIG. 5 is a block diagram showing a configuration of a pager which is an apparatus to which the message receiving method according to the present embodiment is applied. 5, parts that are the same as those in FIG. 1 are given the same reference numerals, and descriptions thereof will be omitted. The pager according to the present embodiment includes a keyword detector 12. The keyword detector 12 detects a keyword that can be configured by hardware such as a shift register, outputs a detection result to the control unit 5, and can detect the keyword at high speed.

Next, the operation will be described. The pager according to the present embodiment is different from the pager according to the embodiment shown in FIG.
, The output of the decoder unit 2 is input to a keyword detector 12 having a hardware configuration configurable by a shift register, and a detection result is obtained. In the present embodiment, the configuration for adding the protect flag can be realized by hardware. In practice, the keyword detector 12 can be configured inside the decoder unit 2.

As described above, in the present embodiment, the load on the control unit 5 can be reduced, and keyword matching is performed by hardware, so that keyword matching can be performed at high speed.

As described above, according to the present invention, an evaluation criterion for the importance of a received message on the receiver side is set to a received message protected by a keyword set for each address where the received message is stored. In this case, it is possible to sufficiently prevent the loss of messages important to the receiver and the sender when the memory space for storing the received message is insufficient.
