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.

Description

technical field

[0001] The present invention relates to a communication system for controlling communication of mobile equipment, a communication control device and mobile equipment used in the communication system, and a communication method for controlling communication of mobile equipment. Background technique

[0002] In the past, there was a communication system for performing data communication between mobile devices using GPRS (General Packet Radio Service). In this communication system, there are GGSN (Gateway GPRS Support Node: Gateway GPRS Support Node) that connects different networks, and a plurality of SGSN (Service GPRS Support Node: Service GPRS Support Node) arranged under the GGSN etc., the mobile device is connected to the network to be connected through the SGSN and the GGSN. In addition, there is also a communication service using a so-called prepaid mobile device, in which a communication usage fee is paid in advance, and communication with a mobile dev...
