摘要： Prioritization of data traffic is a common technique for providing enhanced quality of service (QoS), allowing some traffic to reach its destination on an expedited basis without being obstructed or delayed by other lower-priority traffic. A mechanism is disclosed using the bearer architecture of the evolved packet core (EPC) to provide prioritization of traffic from specific packet data networks (PDNs), as well as over specific bearers. The priority information is requested by the mobile management entity (MME), which is commonly overloaded with traffic to and from multiple users and PDNs. In addition, a mechanism is provided for reducing the frequency of unwanted paging notifications for MMEs that are overloaded.
摘要翻译：数据业务的优先级是提供增强服务质量（QoS）的常用技术，允许一些业务在加速的基础上到达其目的地，而不被其他低优先级业务阻塞或延迟。公开了使用演进分组核心（EPC）的承载架构来提供来自特定分组数据网络（PDN）以及特定承载的业务的优先级的机制。优先级信息由移动管理实体（MME）请求，移动管理实体（MME）通常对来自多个用户和PDN的流量过载。此外，提供了一种用于减少过载的MME的不期望的寻呼通知的频率的机制。

摘要： Methods and systems for providing a dynamic and real time load factor that can be shared with other network elements is disclosed. The load factor can be used in determining the relative load among a set of network elements and in distributing new sessions requests as well as existing session on the set of network elements. The load factor can also be used for determining to which network element a user equipment is handed off. The dynamic load factor can also be shared amongst network elements to determine how the load is balanced among the network elements, such as a mobility management entity (MME).

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： The present invention relates to a mobile node, router device and method of providing to a first type of traffic an enhanced handover function specified for a second type of traffic, wherein a predetermined set of handover destination address parameters is derived from a protocol signaling related to the second type of traffic. This derived set of handover destination address parameters is then used to generate for the first type of traffic a new destination address in accordance with the second type of traffic, and a binding update is initiated for binding at least one original destination address of the first type of traffic to the generated new destination address of the second type of traffic. Thus, handover support can be provided for the first kind of traffic without requiring a dedicated handover protocol for the first kind of traffic.

摘要： There is proposed a mechanism for establishing a secure communication between network elements in a communication network. The network nodes execute an authentication procedure with an authentication network element. The authentication network may also one of the network elements as a gateway element. Then, a respective data key for the network elements authenticated is generated and distributed to the gateway element by using a secure channel between the authentication network element and the gateway element. The data keys are stored the data keys in the gateway element. When a secure communication is to be setup, a respective session key is generated in the network elements intending to participate in the secure communication. The session keys are exchanged between the network elements intending to participate in the secure communication via secure channels between the gateway element and the network elements .

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： This disclosure relates to a system and method for offloading selected data to an alternate communication network. The offloading provides another route for selected packet traffic that can relieve the burden on a mobile operator's network, such as the backhaul and core networks. 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 exponentially increased. Upgrading the existing network that was designed for voice calls is not desirable or practical for many mobile operators. A offload gateway is provided that inspects packets and determines those packets to offload to an alternate network as well as providing mobility management to allow for seamless handoffs and gateway relocations.
