Radio paging receiver and message erasing method

A radio paging receiver comprising:

• receiving means for receiving a radio signal from a base station of a radio paging system;
• first decoding means for picking up one calling address or a plurality of calling addresses assigned to own receiver from the radio signal received by the receiving means and also picking up message data corresponding to the calling address or the calling addresses;
• data storing means for storing the message data picked up by the first decoding means;
• holding means for holding at least of calling address assigned to own receiver;
• character sequence designating means for designating character sequences in stored messages;
• received character sequence retrieving means for detecting whether or not designated character sequences are contained in received messages;
• and
• erasing means for erasing the messages;
• wherein, when designated character sequences are contained in the received messages, the messages are not stored in a storage area but automatically erased after the messages have been checked.

• stored character sequence retrieving means for detecting whether or not designated character sequences are contained in the message data picked up by the first decoding means stored in the data storing means;
• and
• erasing means for erasing the messages;
• wherein, when designated character sequences are contained in the stored messages, the messages are erased collectively concerned messages.

A message erasing method comprising the steps of:

• receiving a radio signal from a base station of a radio paging system;
• picking up one calling address or a plurality of calling addresses assigned to own receiver from received radio signal;
• picking up message data corresponding to the calling address or the calling addresses;
• storing message data being picked up;
• designating character sequences in stored messages;
• detecting whether or not designated character sequences are contained in stored messages;
• monitoring whether or not a predetermined time has lapsed after the messages have been stored;
• and
• erasing concerned messages if designated character sequences are contained in the stored messages and it is detected by the time counting means that the predetermined time has lapsed after the messages are stored.

• picking up one calling address or a plurality of calling addresses assigned to own receiver from the radio signal received;
• picking up message data corresponding to the calling address or the calling addresses;
• storing the message data being picked up;
• designating character sequences in stored messages;
• detecting whether or not designated character sequences are contained in received messages;
• and
• automatically erasing the messages not to store in a storage area after the messages have been checked when designated character sequences are contained in the received messages.

A message erasing method comprising the steps of:

• receiving a radio signal from a base station of a radio paging system;
• picking up one calling address or a plurality of calling addresses assigned to own receiver from the radio signal being received;
• picking up message data corresponding to the calling address or the calling addresses from the radio signal being received,
• storing messages contained in the message data as original messages;
• designating character sequences which are included in the original messages;
• detecting whether or not the designated character sequences are contained in the stored messages;
• and
• erasing concerned messages collectively, the concerned messages being those of the stored messages that contain the designated character sequences.

A message erasing method of a radio paging receiver comprising the steps of:

• receiving a message via a radio transmission from a base station of a radio paging system;
• storing the message as an original message in a storage device of the radio paging receiver;
• inputting a character sequence that is included in the original message, the character sequence being designated by a user;
• retrieving from the storage device the original message that contains the character sequence designated in the step of inputting;
• and
• erasing the message retrieved in the step of retrieving the original message.
