Abstract: A prepaid SMS screening, accounting, and routing node performs prepaid SMS screening and accounting functions. When the prepaid SMS screening, accounting, and routing node receives an SMS message, it determines whether the originating subscriber is a ported subscriber attempting to access an SMSC from the donor network. If the originating subscriber is a ported subscriber attempting to access a donor network SMSC, the SMS message may be discarded. If the originating subscriber is not a ported subscriber, the prepaid SMS screening, accounting, and routing node determines whether the subscriber is a prepaid subscriber. If the subscriber is a prepaid subscriber, the prepaid SMS screening, routing, and accounting node determines whether the subscriber has sufficient credit to send the SMS message. If the subscriber has sufficient credit to send the message, the prepaid SMS screening, accounting, and routing node debits its accounting database and forwards the message to its intended destination. Prepaid SMS screening and accounting may also be performed for messages directed to subscribers with terminating prepaid SMS service. In such situations, the prepaid SMS screening, accounting, and routing node may screen messages to determine whether the terminating subscriber is a prepaid SMS subscriber, and, if so, debit the terminating subscriber's prepaid SMS account.

Abstract translation: 预付费短信筛选，会计和路由节点执行预付费短信筛选和计费功能。 当预付费SMS筛选，计费和路由节点接收到SMS消息时，它确定始发用户是否是从捐赠者网络尝试访问SMSC的移植用户。 如果始发用户是尝试访问供体网络SMSC的移植用户，则可以丢弃SMS消息。 如果始发用户不是移植用户，则预付费SMS筛选，计费和路由节点确定订户是否是预付费用户。 如果用户是预付费用户，则预付费短信筛选，路由和计费节点确定用户是否有足够的信用来发送SMS消息。 如果用户有足够的信用来发送消息，则预付费短信筛选，计费和路由节点将其会计数据库借记，并将消息转发到其预定目的地。 预付短信筛选和计费也可以针对定向到具有终止预付费SMS服务的订户的消息进行。 在这种情况下，预付费短信筛选，计费和路由节点可以屏蔽消息以确定终止订户是否是预付费SMS订户，如果​​是，则借记终止订户的预付费SMS账户。
