用于经由绑定服务提供最大填充链路的系统和方法
Abstract:
本公开涉及支持用于绑定会话的最大填充链路能力。所述最大填充链路能力被配置为控制用户设备的用户设备业务跨所述用户设备支持的绑定数据平面会话的多个承载的分配。所述最大填充链路能力在与所述绑定数据平面会话关联的网关设备处提供，所述网关设备是用于下游用户设备业务的网络网关设备或者用于上游用户设备业务的客户网关设备。所述最大填充链路能力被配置为基于与用户设备数据平面会话关联的策略信息并且基于针对所述用户设备数据平面会话的所述用户设备业务执行的活动业务监视，确定用户设备数据平面会话的用户设备业务到所述用户设备数据平面会话的多个承载的分配。除其他元件以外，系统(100)包括用户设备(UE)(102)、住宅网关/客户端设备(RG/CPE)(110)、多业务接入节点(MSAN)(120)、宽带网络网关(BNG)(130)、演进型节点B(eNodeB)(140)、组合式分组网关(PGW)/服务网关(SGW)(150)。PGW/SGW(150)和RG/CPE(110)在它们之间建立用户设备数据平面会话，其中数据平面提供两个默认承载。例如，通过xDSL接入网络的第一承载隧道包括RG/CPE(110)与MSAN(120)之间的承载链路B11、MSAN(120)与BNG(130)之间的承载链路B12、以及BNG(130)与PGW/SGW(150)之间的承载链路B12。通过3GPP/LTE接入网络的第二承载隧道包括RG/CPE(110)与eNodeB(140)之间的承载链路B21以及eNodeB(140)与PGW/SGW(150)之间的承载链路B22。PGW/SGW(150)根据形成绑定服务的多个下游隧道或承载之间的策略驱动的分配，经由多种接入网络技术将下游业务转发到RG/CPE(110)。活动业务监视的使用可以将否则可能是静态或基本静态的策略转换成动态或潜在动态的策略。
Abstract(English):

The disclosure relates to supporting a maximum fill link capability for a bonded session. The maximum fill link capability is configured to control allocation of user device traffic of a user device across multiple bearers of a bonded data plane session supported for the user device. The maximum fill link capability is provided at a gateway device associated with the bonded data plane session, which is a network gateway device for downstream user device traffic or a customer gateway device for upstream user device traffic. The maximum fill link capability is configured to determine an allocation of the user device traffic of a user device data plane session to multiple bearers of the user device data plane session based on policy information associated with the user device data plane session and based on active traffic monitoring performed for the user device traffic of the user device data plane session. The system (100) includes, inter alia, a User Equipment (UE) (102), a Residential Gateway / Customer Premises Equipment (RG/CPE) (110), a Multi-Service Access Node (MSAN) (120), a Broadband Network Gateway (BNG) (130), an evolved NodeB (eNodeB) (140), a combined Packet Gateway (PGW) / Serving Gateway (SGW) (150). PGW/SGW (150) and RG/CPE (110) establish a user device data plane session therebetween in which the data plane provides two default bearers. For example, a first bearer tunnel traversing the xDSL access network comprises bearer link B11 between the RG/CPE (110) and the MSAN (120), bearer link B12 between the MSAN (120) and the BNG (130), and bearer link B13 between the BNG (130) and the PGW/SGW (150). A second bearer tunnel traversing the 3GPP/LTE access network comprises bearer link B21 between the RG/CPE (110) and eNodeB (140) and bearer link B22 between the eNodeB (140) and the PGW/SGW (150). The PGW/SGW (150) forwards downstream traffic to the RG/CPE (110) via the multiple access network technologies in accordance with a policy-driven allocation between multiple downstream tunnels or bearers forming a bonded service. The use of active traffic monitoring may convert policies that might otherwise be static or substantially static into policies that are dynamic or potentially dynamic.
