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 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： 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： A method enables the electronic surveillance of telecommunications transmissions in compliance with the Communications Assistance for Law Enforcement Act (CALEA) standards. The method involves receiving a data packet intended for transmission to a recipient and storing the data packet in an available buffer. The data packet is then transmitted to the intended recipient and, if it is flagged for surveillance, the data packet is also transmitted to law enforcement officials. This is carried out by retransmitting the original data packet with a new header segment, without creating a copy of the data packet. Once the data packet has been transmitted to the intended recipient and to law enforcement officials (if necessary), the buffer storing the data packet is released such that other data packets can be stored therein.
摘要翻译：一种方法使得能够根据“通信援助执法法”（CALEA）标准对电信传输进行电子监控。该方法涉及接收用于发送给接收者的数据包，并将数据包存储在可用缓冲器中。数据包然后被传送给预定的接收方，如果被标记为监视，则数据包也被传送给执法官员。这是通过用新的标题段重传原始数据分组来实现的，而不创建数据分组的副本。一旦数据分组被传送到预期的接收者和执法官员（如果需要的话），则释放存储数据分组的缓冲器，以便其中可以存储其他数据分组。

摘要： The present disclosure describes an apparatus and method for recognizing the mobile device type by information monitored from multiple means, such as by transparently monitoring Control Plane protocols, and monitoring user plane protocols (for example user agent header in HTTP protocols), and using such information for controlling data-caching operations, selectively delivering content, and selecting alternative interfaces/networks when available. Additionally, the invention discloses methods to propagate the learned information through header enrichment to external devices, such as content servers or CDN devices. The apparatus and methods are applicable to an application/content-aware caching device in a wireless mobile network that operates as an inline transparent device intercepting control plane and user plane protocols.
