摘要： Systems and methods are provided that allow network resources to be shared across geographical distances. This can be achieved by changing the resources available for establishing and handling call or data session processing in an area. A mobility management device can alone or in combination with a DNS server change the size or the resource pool available in some embodiments. The change in resources can be dynamic according to certain predefined conditions or can be setup beforehand to account for daily demand. This sharing of resources can allow more efficient usage of resources available across a geographic region, rather than needed to over-provision each region to account for peak demands.
摘要翻译：提供了允许跨地理距离共享网络资源的系统和方法。这可以通过改变可用于在区域中建立和处理呼叫或数据会话处理的资源来实现。移动性管理设备可以单独地或与DNS服务器组合改变在一些实施例中可用的大小或资源池。根据某些预定义的条件，资源的变化可以是动态的，或者可以预先设置以满足日常需求。这种资源共享可以更有效地利用地理区域可用的资源，而不是过度分配每个区域以满足高峰需求。

摘要： Systems and methods are provided that allow voice and data traffic to be shifted from one chassis to other chassis without interrupting service. Geographic Redundancy (GR) is an inter-chassis redundancy, where the chassis may be a home agent, a packet data serving node, or any combination of wireless networking devices. Additionally, each chassis can have one or more partitions that handle subscriber session traffic and a corresponding redundant partition on a different chassis. The redundant chassis partition can take over all or a portion of the functionality of the active chassis partition if the active chassis or any critical peer servers/gateways communicating with the active chassis should fail. This provides users with uninterrupted service in the case of some failures.
摘要翻译：提供了允许语音和数据业务从一个机箱转移到其他机箱而不中断服务的系统和方法。地理冗余（GR）是机架间冗余，其中机箱可以是归属代理，分组数据服务节点或无线联网设备的任何组合。此外，每个机架可以具有一个或多个处理订户会话流量的分区和在不同机箱上的对应的冗余分区。如果主动机箱或与主动机箱通信的任何关键对等服务器/网关都将失败，冗余机箱分区可以占用主动机箱分区的全部或部分功能。这在一些故障的情况下为用户提供不间断的服务。

摘要： Systems and methods for intercepting and redirecting requests are provided. More particularly, certain information is identified in a packet and the packet is redirected to a specified server. The information that is redirected may be bound for a server in a network that a mobile node is currently visiting, and it is advantageous to fulfill the request in another network instead. The request is redirected to the other network; however, the response to the request may be modified changing the source address and other information so that the response appears to have originated from the server in the visited network to which the mobile node sent the request. Load balancing may also be incorporated when redirecting requests from one or more mobile nodes.

摘要： Methods and systems are disclosed that provide accounting in an access gateway of a communication network. Logic can be implemented in an access gateway to provide accounting in an access gateway when the data is tunneled or encapsulated by a protocol when passing through the access gateway. The access gateway can perform inspections on the data to determine what portions of the data are user payload data and be included in a count and what portions of the data can be ignored, such as control packets and overhead information on the packet. The logic can also be deployed in next generation networks, such as long-term evolution, to provide accounting at the access gateway in some situations.

摘要： A system and method for providing services to packet flows in a communication network. The services include enhanced charging, stateful firewalls, traffic performance optimization (TPO) and advanced services such as content differentiated charging, per-subscriber stateful firewalls, and VPNs, for example. A gateway can be used to route each packet flow through the services on a per-subscriber basis by inspecting accounting messages and checking subscriber profiles prior to setting up a new packet flow session. By directing the packet flow through the services requested latency can be reduced as well as the need to have equipment for each session regardless of whether the service is provided to the packet flow. The services can be provided in-line as well.

摘要： This disclosure relates to an apparatus and method for providing service redundancy among devices in a communication network. The devices can be, for example, a mobility management entity (MME), a serving gateway (SGW), a PDN gateway (P-GW), a call session control function (CSCF), a SGSN, a GGSN, or any other device implemented on a chassis. The redundancy includes a geographic redundancy where the devices are remotely located from one another to prevent a service outage. The devices can provide redundancy to multiple other devices, such that one device serves as a backup to multiple other devices. The information used to provide service to a mobile node such as user equipment can be backed up on the redundancy device and the device can advertise the same routing information to the network so the network is unaware of any change.

摘要： Systems and methods for bridging packet flows to bypass call legs and/or tunnels are provided. A tunnel initiator, which can be an access gateway, a foreign agent, and a mobility anchor point, for example, provides a bypass for certain packets that have a destination serviced by the same tunnel initiator. The bridge allows the packets to bypass a backhaul loop and reduces latency and frees bandwidth for other purposes in the network. The bridging can be implemented in a tunnel initiator for mobile to mobile packet flows, mobile to land line packet flows, and land line to mobile packet flows. Route optimization can also be provided in certain embodiments.
摘要翻译：提供了将分组流桥接到旁路呼叫支路和/或隧道的系统和方法。例如，可以是接入网关，外部代理和移动性锚点的隧道启动器为具有由相同隧道启动器服务的目的地的某些分组提供旁路。桥接器允许数据包绕过回程循环并减少延迟并释放带宽用于网络中的其他目的。桥接可以在用于移动到移动分组流，移动到陆地分组流和陆地线到移动分组流的隧道发起者中实现。在某些实施例中也可以提供路由优化。

摘要： Systems and methods are provided to allow detection of the load conditions on network devices. The load detection can occur using a mobility management device to track establishment of sessions and attempts at session establishment to determine the loading conditions on various network devices. This information can then be used by a selection logic to determine which devices are selected to send session establishment messaging for new session establishment requests. This can provide quicker setup times as highly loaded network devices or network devices experiences other failures are selected less until conditions are back to normal.

摘要： This disclosure relates to systems and methods for paging devices in a communication network. A network device providing mobility management through control messaging can be assigned a number of cell sites in a tracking area. The network device such as a mobility management entity (MME) can use a criteria or heuristic based implementation to provide a hierarchy for contacting a mobile device with a page. The criteria or heuristic based implementation can page a subset of the total number of cell sites in a tracking area and expand the subset after unsuccessful attempts to page the mobile device. The implementation can also be tailored to offer a range of options for page requests received by a network device, which can be based on such things as the application sending the page request.
