Paging device having last-to-first sequential character memory search routine
First Claim
1. A paging device having a message display function, comprising:
- receiving means for receiving information of a calling number;
input means for inputting a calling number including an area code to be registered;
memory means having a memory area for storing plural registered calling numbers inputted by said input means;
search means for comparing the information of a calling number received by said receiving means with a character string of a registered calling number stored in said memory means in order from a last character to a first character so as to search a registered calling number composed of at least a same number of characters as the received calling number and including a same character string starting with a last character as a character string from the last character to the first character of the calling number received by said receiving means; and
display means for displaying the registered calling number searched by said search means.

Abstract
A paging device with a message display function enables a person who possesses the paging device to register plural calling numbers including an area code in a memory section by operating an attached input section. The paging device is arranged such that upon receiving a calling number, a calling number corresponding to the received calling number is searched in last-to-first sequential character order, from a calling number directory registered in the memory section, and the calling number including the area code is displayed on a display section. In this way, even when a calling person transmits the calling number without the area code, the calling number including the area code which is registered beforehand is displayed on the display section of the paging device.

16. A paging device having a message display function comprising:
-
receiving means for receiving information comprising a calling number, said information may or may not include an area code; input means for inputting a calling number that includes an area code as a registered calling number; memory means having a memory area for storing plural registered calling numbers inputted by said input means; search detecting means for detecting a registered calling number corresponding to a calling number received by said receiving means, which may or may not include an area code, said search detecting means comparing a character string of a received calling number against a character string of each registered calling number stored in memory, wherein said comparing is performed between characters in respective character strings in a last-to-first sequential character order that begins with respective last characters of said received calling number and a registered calling number and concludes with a first character of said received calling number and a corresponding last-to-first sequential character of said registered calling number; and display means for displaying said corresponding registered calling number, including said area code, detected by said search detecting means. - View Dependent Claims (17, 18)

19. A method for displaying information associated with a calling number from a transmission received in a paging device having a memory, a means for inputting information into the memory, a message display function, and a display, comprising the steps of:
-
a) registering a calling number along with associated additional information in said paging device by inputting said calling number along with said additional information in a memory in said paging device, said memory means having a memory area for storing plural calling numbers and said additional information; b) upon receiving a transmitted calling number, detecting a corresponding calling number registered in said paging device by comparing a character string of a received calling number against a character string of each registered calling number stored in memory, said comparing performed between characters in respective character strings in a last-to-first sequential character order that begins with respective last characters of said received calling number and a registered calling number and concludes with a first character of said received calling number and a corresponding last-to-first sequential character of said registered calling number; and displaying said corresponding registered calling number detected in step b), including said area code.

20. A paging device having a message display function comprising:
-
an RF receiver section, said receiver section receiving a transmitted calling number; a memory, said memory having a memory area for storing plural registered calling numbers including associated area code information; a central processor; a registered calling number search routine stored in said memory and operating said central processor to detect a stored registered calling number corresponding to a calling number received by said receiving means, said search routine comparing a character string of a received calling number against a character string of each registered calling number stored in memory, wherein said comparing is performed between characters in respective character strings in a last-to-first sequential character order that begins with respective last characters of said received calling number and a registered calling number and concludes with a first character of said received calling number and a corresponding last-to-first sequential character of said registered calling number; and a display device, said display device displaying the registered calling number including area code detected by said search routine.
