摘要： The present invention identifies methods and procedures for correlating control plane and user plane data, consolidating and abstracting the learned and correlated data in a form convenient for minimizing and exporting to other network devices, such as those in the Core Network and the Access Network, or the origin server, CDN devices or client device. These correlation methods may use Control Plane information from a plurality of interfaces in the RAN, and User plane information from other interfaces in the RAN or CN. IF the device is deployed as an inline proxy, this information may be exported using in-band communication, such as HTTP extension headers in HTTP Request or Response packets, or another protocol header, such as the IP or GTP-U header field. Alternatively, this information can be exported out-of-band using a separate protocol between the RAN Transit Network Device (RTND) and the receiving device.

摘要： A method of learning and identifying two unidirectional GTP-U tunnels corresponding to a user equipment (UE) in a device placed in a LTE network, where the device acts as a transparent proxy intercepting user plane and control plane protocols on the S1 interface, is disclosed. Methods of pairing the two unidirectional tunnels that belong to same UE, when there is no control plane information or when there is Control Plane information, but the NAS portions of the S1 Control that contain bearer IP addresses are encrypted, are disclosed. Control plane and user plane methods for associating GTP-U tunnels and the corresponding bearer plane IP addresses are identified. Additionally, methods for detecting mobility of a UE, as it moves from the coverage area of one E-NodeB to another, are disclosed. Methods for constructing an eNodeB topology map are also disclosed.

摘要： An application mobility-management entity (“AME”) in a radio-access network detects movement of a mobile device and routes application data for already-active application streams associated with the mobile device to the device's new location by establishing a connection to a second AME in the radio-access network. The second AME merges forwarded application data from/to the first AME for previously active application streams with the new application streams (e.g., new TCP connections) locally and forwards to/from the mobile device through the radio access network elements.

摘要： The current invention is applicable to a RAN-cache or proxy operating in a wireless mobile network that is functioning as a transparent inline device intercepting wireless mobile protocols such as UMTS, LTE, WIMAX, CDMA etc.), or a traffic off-load device connected to multiple interfaces towards the Core/Internet. The current invention identifies methods for pre-fetching content by emulating portions of a mobile client for gaining connectivity through the mobile-core network, or to use session contexts of other mobile clients in a way not to significantly effect charging and billing for the preloaded content. The pre-load decision of what to pre-load and when to pre-load may be locally derived within the RAN-cache/Proxy device, or in-coordination with a locally connected CDN (Content Delivery Network) device. Other embodiments of the current invention include the RAN-cache/Proxy providing interconnectivity from the locally connected CDN device to other CDN devices through the Mobile Core Network (SGSN/GGSN in UMTS, S-GW/P-GW in LTE etc.).

摘要： The current invention defines a device and a method of logically inserting the device between two other network devices, for example, in a 3GPP Radio Access Network. The device transparently monitors and interacts with one or more control protocol layers in the two neighboring devices. The invention defines methods by which the intercepting node selectively passes through or proxies (selectively modifying portions of the protocols content) in such as way that the neighbor nodes are un-aware of the intercepting device. The proxy operation implies that the intercepting node is capable of terminating some protocol elements, injecting some protocol elements, or modifying protocol elements before forwarding them in such a way that the operation is transparent to neighboring nodes. These selective insertion/modifications facilitate identifying signaling connections for specific mobile clients, and enhancing and modifying service features for dataplane accesses for those client devices, while transparently passing other protocol messages.
摘要翻译：本发明定义了在例如3GPP无线电接入网络中的两个其他网络设备之间逻辑地插入设备的设备和方法。该设备透明地监视和与两个相邻设备中的一个或多个控制协议层进行交互。本发明定义了截取节点选择性地通过或代理（有选择地修改协议内容的部分）的方法，使得邻居节点不知道拦截设备。代理操作意味着拦截节点能够终止一些协议元素，注入一些协议元素，或者在转发它们之前修改协议元素，使得该操作对相邻节点是透明的。这些选择性插入/修改有助于识别特定移动客户端的信令连接，并且在透明地传递其他协议消息的同时增强和修改用于那些客户端设备的数据库接入的服务特征。
