Abstract: Services with policy control may be provided. A computing device may receive registration information associated with a border device. The registration information may comprise information identifying a service provided by a server associated with the border device, information identifying the border device, and policies associated with the service. Then an address for the server may be determined. Next a request may be received comprising the information identifying the service provided by the server. In response to receiving the request comprising the information identifying the service provided by the server, the address for the server, the information identifying the border device, and the policies associated with the service may be provided.

Abstract: Systems and methods are disclosed for processing framed routes initiated by user equipment (UE) at customer-premises equipment (CPE) and gateways using protocol configuration options (PCO). The PCO can include encoding and decoding framed route information using a PCO information element (IE). The framed route information can include a framed route and a virtual private networking routing and forwarding (VRF) name. The framed route information can also include a tunnel identifier and a packet data protocol (PDP) address. The gateway can include a packet data network gateway (PGW) and a gateway general packet radio service support node (GGSN). When the gateway receives an attach request message from the UE with the encoded PCO, the gateway decodes the PCO to extract the framed route and VRF name, associates a tunnel identifier and PDP address with the extracted framed route and VRF name, and installs the framed route in a corresponding VRF.

Abstract translation: 公开了用于处理由用户设备（UE）在客户端设备（CPE）和使用协议配置选项（PCO））的网关发起的框架路由的系统和方法。 PCO可以包括使用PCO信息元素（IE）对成帧路由信息进行编码和解码。 框架路由信息可以包括框架路由和虚拟专用网络路由和转发（VRF）名称。 成帧路由信息还可以包括隧道标识符和分组数据协议（PDP）地址。 网关可以包括分组数据网络网关（PGW）和网关通用分组无线业务支持节点（GGSN）。 当网关从具有编码PCO的UE接收附加请求消息时，网关对PCO进行解码以提取成帧路由和VRF名称，将隧道标识符和PDP地址与提取的成帧路由和VRF名称相关联，并安装框架 路由在相应的VRF中。
