    • In general, techniques are described for selectively applying and reusing filters stored in a router. In one example, a method includes receiving a network access request from a first user. The method also includes selecting a candidate rule group associated with the packet flow, wherein the candidate rule group comprises one or more currently deployed rules of an existing rule group on the computing device that are currently installed within a forwarding plane and are being applied by the forwarding plane to network traffic associated with a second user. The method also includes installing a new rule group comprising the one or more currently deployed rules of the existing rule group and one or more new rules associated with the first user and not currently installed within a forwarding plane. The method also includes applying each rule of the new rule group to network traffic associated with the first user.

    • In general, the invention is directed to techniques for breaking out mobile data traffic from a mobile service provider network to a packet data network. For example, as described herein, a breakout gateway device (BGW) receives a first service request and data traffic for a data session associated with the requested service from a mobile device in a radio access network, wherein the first service request is addressed to a serving node of a mobile core network of the mobile service provider network, and wherein the data traffic is destined for the PDN. A control packet analysis module forwards the first service request from the breakout gateway device to the serving node. A breakout module of the BGW bypasses the serving node by sending the data traffic from the breakout gateway device to the PDN on a data path from the radio access network to the PDN.
    • 通常,本发明涉及用于将移动数据业务从移动业务提供商网络分解成分组数据网络的技术。 例如,如本文所述,分组网关设备(BGW)从无线电接入网络中的移动设备接收与所请求的服务相关联的数据会话的第一服务请求和数据业务,其中第一服务请求被寻址到 移动服务提供商网络的移动核心网络的服务节点,并且其中数据业务指向PDN。 控制分组分析模块将第一服务请求从分组网关设备转发到服务节点。 BGW的突围模块通过在从无线接入网络到PDN的数据路径上将数据业务从分组网关设备发送到PDN来绕过服务节点。

    • In general, techniques are described for decentralizing handling of subscriber sessions within a gateway device of a mobile network. A mobile network gateway comprises a data plane having a plurality of forwarding components to receive session requests from a mobile service provider network in which the mobile network gateway resides. A control plane comprises a plurality of distributed subscriber management service units coupled by a switch fabric to the data plane. Each of the subscriber management service units serve as anchors for communication sessions for mobile devices that are accessing one or more packet data network by the mobile service provider network. A request delegation module within each of the forwarding components directs the session requests to the subscriber management service units unit to provide management services for the sessions requested by the mobile device.
    • 一般来说,描述了用于在移动网络的网关设备内分散处理用户会话的技术。 移动网络网关包括具有多个转发组件的数据平面,用于从移动网络网关驻留的移动服务提供商网络接收会话请求。 控制平面包括由交换结构耦合到数据平面的多个分布式用户管理服务单元。 每个用户管理服务单元用作移动服务提供商网络正在访问一个或多个分组数据网络的移动设备的通信会话的锚点。 每个转发组件内的请求委托模块将会话请求引导到用户管理服务单元单元,以为移动设备请求的会话提供管理服务。

    • In general, techniques are described for handling errors in subscriber session management within mobile networks. A downstream mobile gateway comprising a forwarding unit and a service unit may implement the techniques. The forwarding unit receives a packet that includes a destination address for a subscriber and a tunnel endpoint identifier (TEID). The service unit determines whether the TEID is associated with one of a number of subscriber records that store session data for current sessions associated with subscriber devices to communicate with the mobile network. In response to determining that the TEID is not associated with one of the subscriber records, the service unit generates a message that includes the TEID and the destination address and indicates that the downstream mobile gateway has determined that the TEID is not associated with one of the subscriber records. The forwarding unit then sends the message to the upstream mobile gateway.
    • 通常,描述了用于处理移动网络内用户会话管理中的错误的技术。 包括转发单元和服务单元的下游移动网关可以实现这些技术。 转发单元接收包括用户的目的地地址和隧道端点标识符(TEID)的分组。 服务单元确定TEID是否与存储与用户设备相关联的当前会话的会话数据的多个订户记录之一相关联以与移动网络进行通信。 响应于确定TEID不与订户记录中的一个相关联,服务单元生成包括TEID和目的地地址的消息,并且指示下游移动网关已经确定TEID不与其中的一个相关联 用户记录。 转发单元然后将消息发送到上游移动网关。
