Abstract: The present invention provides a method and system for dynamic filtering of data packets at an access gateway in a communication network. According to the method, a policy server receives a request for registration with the network from a network node. The server verifies the network node identity and selects the corresponding security policy for the network node. The selected security policy is indicated by the server to a network access gateway. The network access gateway selects the indicted security policy. The selected security policy is applied for the communication between the network node and the network.

Abstract: A GRE tunnel initiator and a tunnel endpoint can exchange GRE Heartbeat messages to provide status information about the tunnel endpoint. The tunnel endpoint can send the tunnel initiator a GRE Heartbeat message through an established GRE tunnel. The GRE Heartbeat messages can be sent at different times while the GRE tunnel is active, and they can indicate to the GRE tunnel initiator that the tunnel endpoint remains active.

Abstract translation: GRE隧道启动器和隧道端点可以交换GRE Heartbeat消息，提供有关隧道端点的状态信息。 隧道端点可以通过建立的GRE隧道向隧道发起者发送GRE心跳消息。 当GRE隧道处于活动状态时，可以在不同时间发送GRE心跳消息，并且可以向GRE隧道发起方指示隧道端点保持活动状态。

Abstract: The RF receiver for the CDMA mobile communication BTS system according to the present invention realizes the system with an analog down-converter to process multiple FA's and generate IF signals of 70 MHz having a bandwidth corresponding to the multiple FA's with a mixer, and a digital down-converter to digitally process the respective FA's through A/D conversion of the IF signals of 70 MHz, allowing simple multi-FA(3FA)-based expansion. Also, the system needs only one analog down-converter for simultaneously processing 3 FA's and one digital down-converter for digitally processing the IF signals from the analog down-converter by FA's to down-convert the IF signals to baseband signals, thereby reducing the size of the system and hence the hardware cost. The system can be implemented with higher stability by digitally processing the down-conversion of the analog IF signals of multiple FA's to the baseband signals.

Abstract translation: 根据本发明的用于CDMA移动通信BTS系统的RF接收机实现具有模拟下变换器的系统来处理多个FA并且利用混频器产生具有对应于多个FA的带宽的70MHz的IF信号，并且数字 下转换器通过对70 MHz的IF信号进行A / D转换来对相应的FA进行数字处理，从而允许简单的多FA（3FA）扩展。 此外，该系统只需要一个模拟下变频器，用于同时处理3个FA和一个数字下变频器，用于通过FA对来自模拟下变频器的IF信号进行数字处理，以将IF信号下变频为基带信号，从而减少 系统的大小以及硬件成本。 通过将多个FA的模拟IF信号的下变频数字处理到基带信号，可以实现更高的稳定性。

Abstract: A multilevel hierarchical feature rights management system (100) provides an efficient way of allocating feature keys. Sub-agents (140) are provisioned or activated with application software having features. The sub-agents request permissions from feature rights management agents (120) to use these features. The feature rights management agents (120) receive feature keys over a network (130) from a feature rights server (110). The feature rights management agents (120) then permit sub-agents (140) to use their provisioned features. In a further aspect of the invention the sub-agents (140) voluntarily release feature permissions rather than the server (110) or the agents (120) forcing the sub-agents (140) to revoke rights.

Abstract: In a data packet system (100) comprised of a plurality of processing platforms that are each at least potentially in-line with respect to a flow of data packets, upon receiving (401) an installation of a data packet filter, automatically selecting (402) where, from amongst that plurality of process platforms, to effect the data packet filter. This can comprise, if desired, parsing of the filter to ascertain its characterizing requirements and accessing information regarding the processing platforms to determine which platforms are capable of effecting those requirements. Numerous other factors can also be taken into account to aid in assuring an appropriate selection.
