A service control point transmits a recharge request message or advice of charge to a mobile client resident in a wireless communications device. The message is first received by a wireless telephony application server that then forwards the message to a wireless access protocol gateway. The wireless access protocol gateway then sends the request to the mobile client. The user of the mobile client responds with an affirmative or negative answer to the request to recharge the prepaid telephone airtime account. The service control point then either recharges the account as instructed or lets the account expire, depending on the response from the user.

While maintaining the conference call, the telephone user simultaneously uses the wireless access protocol browser to perform data communication. The user then relays the information accumulated from the data communication back to the conference call.
