    Abstract: Methods and systems are provided for filtering packets in a wireless communication system in the to-subscriber direction. This filtering is at least in part based on RF circuit state information. For example, a packet filter is used that either permits or denies packets from reaching a mobile subscriber based on whether there is already an established RF circuit to provide packets to the mobile subscriber. Alternatively, or in addition, the packet filter may consider the history of circuit state transitions associated with a particular mobile subscriber, the percentage (or aggregate number) of available airlink resources that are currently in use, and/or the length of time associated with the dormancy of a mobile subscriber's RF connection. In various embodiments, the packet filter may cause one or more packets to be sent to a mobile subscriber using a special data channel that does not require the establishment of an RF circuit.

    Abstract translation: 提供了方法和系统，用于按照用户方向对无线通信系统中的分组进行过滤。 该滤波至少部分基于RF电路状态信息。 例如，使用分组过滤器，其基于是否已经存在建立的RF电路来向移动订户提供分组，允许或拒绝分组到达移动订户。 或者或另外，分组过滤器可以考虑与特定移动用户相关联的电路状态转换的历史，当前正在使用的可用空中链路资源的百分比（或总数）和/或与 移动用户的RF连接的休眠。 在各种实施例中，分组过滤器可以使用不需要建立RF电路的特殊数据信道来使一个或多个分组被发送到移动订户。
