Prepaid wireless telephone account regeneration in a wireless access protocol system

Service control equipment transmits advice or the recharge request message of the charge to the mobile client which exists in radio communication equipment (301). A message is first received by the radio telephony application server, and, subsequently to a radio access protocol gateway, a server transmits a message (302). A radio access protocol gateway ranks second and sends a demand to a mobile client (303). The user of a mobile client answers by affirmative or negative reply to a demand, in order to carry out recharge of the prepaid telephone duration-of-call account (304 or 310). Service control equipment is account as it ranked second and was ordered by the response from a user -- recharge -- carrying out (306) -- or account is terminated (312). [Selection figure] Fig. 3
