Title:

COMMUNICATION SYSTEM, COMMUNICATION CONTROL DEVICE, COMMUNICATION METHOD, AND MOBILE DEVICE

Document Type and Number:

WIPO Patent Application WO/2012/086787

Kind Code:

A1

Abstract:

When a communication eligibility unit (216) of an SGSN (20) determines, while a mobile device (10) is communicating, that the mobile device (10) cannot continue communicating on the basis of the communication volume balance, an access point information extraction unit (201) extracts APN information for APNs having a residual communication volume balance, and the extracted APN information is communicated to the mobile device. An access point information acquisition unit (104) of the mobile device (10) acquires the APN information regarding the residual communication volume balance. The next time communication begins, the APN information regarding the residual communication volume balance is sent to the SGSN (20) and communication is carried out. Thus, APN information regarding the residual communication volume balance can be ascertained on the mobile device (10) side, and communication can be carried out on the basis of the APN information regarding the residual communication volume balance, thereby enabling highly convenient communication connections to be made.
