摘要： A robust IP/UDP/RTP header compression mechanism is provided to correctly reconstruct IP/UDP/RTP headers in the presence of packet losses and errors of unreliable networks. The header compression mechanism may include a compressor/de-compressor implemented for operation similarly to RFC 2508 but designed specifically to address robustness when employed in lossy and error-prone networks. The robust header compression scheme requires that, when a second-order difference of a field is non-zero, not only a particular RTP packet whose second-order difference is non-zero is sent with the new first-order difference, but also those following packets are also sent with the new first-order difference as long as: (a) a pediod pre-determined by factors such as channel characteristics (e.g., link round-trip time RTT/inter-packet separation); or (b) a positive confirmation is received by the compressor that the new first-order difference has been correctly received. In addition, during a period of communicating with the new first-order difference, if the corresponding RTP field changes again with non-zero second-order difference, the "new" first-order difference is combined with the original first-order difference such that the two first-order differences may be appended together as a simple means of communicating the two-order differences reliably.
摘要翻译：在存在分组丢失和不可靠网络的错误的情况下，提供了稳健的IP / UDP / RTP头压缩机制来正确地重建IP / UDP / RTP报头。报头压缩机制可以包括类似于RFC 2508实现的用于操作的压缩器/解压缩器，但专门设计用于在有损和易错的网络中使用时解决鲁棒性。鲁棒的报头压缩方案要求当字段的二阶差异不为零时，不仅以二阶差异为零的特定RTP分组与新的一阶差异一起发送，只要：（a）通过诸如信道特性（例如，链路往返时间RTT /分组间分离）等因素预先确定的小区，以下分组也被发送与新的一阶差异; 或（b）压缩机接收到正确接收到新的一阶差分的肯定确认。另外，在与新的一阶差的通信期间，如果相应的RTP字段再次以非零二阶差进行改变，则将“新”一阶差与原始一阶差相结合，两个一阶差分可以作为将两阶差分可靠地传达的简单方法附加在一起。

摘要： A method and apparatus which permits access, by intermediate nodes between source and destination nodes, to selected information such as transport level information, normally included in a payload of a packet upon which encrypting security processing has been performed according to an encrypting security protocol. In the present invention, prior to performing encrypting security processing on the packet, according to the security protocol, information related to selected information normally included in a payload of the packet is stored in a field in the header of the packet where the field is not subject to the encrypting security processing. Thereafter, encrypting security processing according to the security protocol is performed on the packet. The packet including the header having stored therein information corresponding to the selected information normally included in the payload and the payload upon which encrypting security processing has been performed is then transmitted on the packet switched network to its destination. Since the information related to the selected information normally included in the payload of the packet is stored in the header of the packet, access to the selected information by the intermediate nodes between source and destination nodes in a packet switched network is possible.

摘要： A network node self-retirement apparatus, system, and method is provided. The system includes a first network node, a second network node, and a plurality of network nodes. The first network node is configured to monitor a power and traffic level of the first network node and determine an operational weight based thereon. The first network node is further configured to compare the operational weight to a selected operational weight to determine a relationship between the operational weight and the selected operational weight. The first network node is further configured to execute a network node self-retirement procedure when the relationship satisfies a selected condition and to send the operational weight to at least one network node when the relationship does not satisfy the selected condition. The first network node may also determine a network topology based on operational weights received from other network nodes.

摘要： As the proliferation of data rich content and increasingly more capable mobile devices has continued, the amount of data communicated over mobile operator's networks has increased. Upgrading the existing network that was designed for voice calls is not desirable or practical for many mobile operators. This disclosure relates to a mobility edge gateway that resides on the edge of the core network and can provide one or more services such as call localization, offloading of traffic, session management, and content streaming. The call localization involves identifying calls that can be maintained at the edge of the network and bridging the calls at the mobility edge gateway to bypass the core network. The offloading involves identifying traffic and offloading the traffic to the Internet or another network to bypass the core network. These services can relieve congestion on the core network of mobile operator's networks.

摘要： An apparatus and method are provided in which multiple options are configured to deliver a base-station ID (BSID), which acts as a trigger for an initiation of a handover at an access gateway level. The handover triggers may be based on a proactive handover between at least one mobile station and a gateway and base station in a serving and target networks or on a reactive handover in which the at least one mobile station does not perform any handover preparation prior to the handover. In addition, the handover trigger may be based on a network initiating and controlling the handover.

摘要： Systems and methods are disclosed that provide self management of network devices in a communication network. These management abilities allow a network device to perform functions, for example, that improve resource distribution, allow for maintenance and upgrades, and provide session management and policy enforcement in a coherent and organized fashion. In a self organizing network (SON), some network devices can be configured to provide self-configuration and self-optimizing capabilities to provide the ability to automate certain operations and management functions and system management functions. The SON incorporates self-configuration, self-optimization, monitoring, and operation management to allow the network devices to be inserted into the network and operate with little to no human intervention.

摘要： A method and apparatus for avoiding packet reordering in multiple-class, multiple-priority networks. The present invention provides a queue implementation technique that can be used in multiple-class, multiple-priority networks such as Differentiated Services networks to ensure that packets are serviced without reordering. The queue implementation technique maintains performance isolation between different classes under some scheduling disciplines and can identify scheduling disciplines which do not degrade the performance seen by the lower priority traffic classes. The system includes a first queue for receiving packets associated with a first traffic class, the packets being arranged in the first queue as in-profile packets and out-profile packets and a second queue for storing pointers associated with the out-profile packets, wherein the packets in the first queue comprise doubly-linking, and the pointers associated with the out-profile packets in the second queue point to corresponding out-profile packets in the first queue as well as to a previous and next element in the second queue.
