Communication control method

Abstract

A communication control method for controlling data communication conducted between a portable information communication terminal and a data communication apparatus via a communication network including a radio communication network includes the steps of: determining whether data communication between a portable information communication terminal and a data communication apparatus has been interrupted by disconnection of a communication line; and in response to normal termination of data communication between a portable information communication terminal and a data communication apparatus, clearing accounting on data communication that was interrupted between said portable information communication terminal and a data communication apparatus by disconnection of a communication line within a predetermined time before the normal termination of the data communication.

       3 . A communication control method for controlling data communication conducted between a portable information communication terminal and a data communication apparatus via a communication network including a radio communication network, said communication control method comprising the steps of: 
 in response to interruption of data communication between a portable information communication terminal and a data communication apparatus caused by disconnection of a communication line, distributing preferential connection information for connecting said portable information communication terminal preferentially, to radio base stations;    receiving said preferential connection information, and securing a vacant line; and    in response to detection of a call incoming request from a portable information communication terminal that meets said preferential connection information, connecting preferentially said portable information communication terminal by using said secured vacant line.

       7 . A communication control system for controlling data communication conducted between a portable information communication terminal and a data communication apparatus via a communication network including a radio communication network, said communication control system comprising: 
 a communication situation control section responsive to interruption of data communication between a portable information communication terminal and a data communication apparatus caused by disconnection of a communication line, for distributing preferential connection information for connecting said portable information communication terminal preferentially, to radio base stations; and    a line control section for receiving said preferential connection information, and securing a vacant line, and responsive to detection of a call incoming request from a portable information communication terminal that meets said preferential connection information, for connecting preferentially said portable information communication terminal by using said secured vacant line.

       11 . A program that makes a computer function as a communication control system for controlling data communication conducted between a portable information communication terminal and a data communication apparatus via a communication network including a radio communication network, said program making the computer function as: 
 a communication situation control section responsive to interruption of data communication between a portable information communication terminal and a data communication apparatus caused by disconnection of a communication line, for distributing preferential connection information for connecting said portable information communication terminal preferentially, to radio base stations; and    a line control section for receiving said preferential connection information, and securing a vacant line, and responsive to detection of a call incoming request from a portable information communication terminal that meets said preferential connection information, for connecting preferentially said portable information communication terminal by using said secured vacant line.
