Communication terminal unit capable of receiving a message and method for identifying a message sender in the same
View Patent ↗A communication terminal unit capable of identifying a message sender by comparing a source address attached to a received message with an address registered in a memory of the unit in advance, which can identify the message sender even if the source address has an error by regarding the erroneous source address to be the same as the registered address when the difference between these two addresses is within a predetermined permissible range.
