摘要： Methods and systems for providing redundancy in servicing packet data communications within wireless mobile data networks are disclosed. More particularly, the method and system for provide a redundant Home Agent with the ability to assume the role of the primary Home Agent in the event of a primary Home Agent network, software, or other failure. The redundancy allows Home Agent services to remain functional in the case of a failure of one of the Home Agents in the redundant group, which may be composed of one or more Home Agents. The Home Agents can be located in geographically separate areas to ensure that a network outage event in one geographic area does not cause subscriber services to be impacted.
摘要翻译：公开了在无线移动数据网络内为分组数据通信提供冗余服务的方法和系统。更具体地，提供冗余归属代理的方法和系统能够在主归属代理网络，软件或其他故障的情况下承担主归属代理的角色。冗余允许归属代理服务在冗余组中的一个归属代理的故障的情况下保持功能，冗余组可以由一个或多个归属代理组成。归属代理可以位于地理上分开的区域，以确保一个地理区域内的网络中断事件不会导致用户服务受到影响。

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。

The Home Agents can use a service redundancy protocol which is composed of messages that are sent between the redundant group of Home Agents. The messages allow the Home Agents to, for example, back up call session information, check on the status of one another, and share priority information.
