Abstract: A mobile communications device receives an indication of a balance from a server when establishment of a voice call or sending of a message is requested. The mobile communications device determines whether the balance is sufficient to place the voice call or send the message over a mobile network. If the balance is sufficient to place the voice call or send the message over the mobile network, the voice call is established or the message is sent under normal operating conditions. If the balance is insufficient to place the voice call or send the message over the mobile network, a grace period is activated and the voice call is established or the message is sent during the grace period over an available wireless local-area network.

Abstract: A database stores unique associations between account identifiers and mobile-network telephone numbers assigned by a mobile network to mobile communications devices. The account identifiers are also associated with voice-over-IP (VoIP) telephone numbers. Voice calls between the mobile communications devices are made as voice-over-IP (VoIP) calls using respective VoIP telephone numbers. Tracking of the VoIP calls is performed through the mobile network using respective mobile-network telephone numbers, so that a prepaid balance can be enforced.

Abstract translation: 数据库存储由移动网络分配给移动通信设备的帐户标识符和移动网络电话号码之间的唯一关联。 帐户标识符也与IP语音电话号码相关联。 通过使用相应的VoIP电话号码将移动通信设备之间的语音呼叫设为语音IP（VoIP）呼叫。 通过移动网络使用各自的移动网络电话号码来执行VoIP呼叫的跟踪，从而可以执行预付余额。
