    Abstract: A method for delivering content to a user from a Radio Access Network (RAN) cache without waiting for a response from the content server if the user's request meets the criteria of caching and expiration tags on previously cached content. If there is no cached copy of the content in the local device, the local device may treat the request as a cache miss, propagating the user's request and the corresponding response through one or more core network devices for accounting and/or charging. In the case of a cache hit, the local device may return the requested object from local cache and may forward each user content request to the content provider so that the mobile network's accounting devices can register the appropriate charge to the user's account. The local device may then update the RAN cache and expiration timers based on the response from the content servers.

    Abstract: A method of generating optimal packet workload for achieving a balance between maximizing cell throughput and fairness across multiple users in UMTS/HSPA Network is disclosed. The packet scheduler of the current invention enhances the performance of other schedulers, such as Proportionally Fair Scheduler in NodeB and RNC in UMTS/HSPA Networks by monitoring recent RAN bandwidth to each mobile device, and increasing buffer occupancy of high rate data-flows in the RAN devices. The scheduler uses the desired performance goals of maximum cell throughput and fairness at various network congestion levels, and controls egress burst rate while delivering packets to the RAN (Radio Access Network).

    Abstract: 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.

    Abstract: 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.).

    Abstract: 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.

    Abstract: 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.
