摘要： Methods for pipelining, piggybacking, and transporting cross layer parameters through a network to reduce round-trip times are disclosed. Application activation, such as accessing a web-site through the internet, currently uses several protocols, including DNS Name resolution, establishing a TCP connection, sending HTTP Request and getting HTTP-Response that contains the web-page data, before the data from the web-site can be displayed to the user. Such operations take several round-trips through the transit network and are of the order of 100 to 200 milliseconds in the wireless access network in the best case. A method of generating a multi-part message to reduce these round trip is disclosed, as well as a proxy device which minimizes client side round trips while utilizing standard messaging in the wireline network. The invention includes client side user parameter gathering when specifying the application first (pre-fix), or specifying the application last (post-fix).

摘要： Methods and applications for modulating the vibration mode of cellular handsets using patterned sequences are disclosed. This modulation allows additional information to be conveyed, thereby communicating messages in a variety of domains before the user responds to the vibration alert. This modulation may cause different patterns of vibration to convey additional information such as the importance of the call, identity of the caller, and other such information. The invention further extends vibration modulation to additional gaming and music & entertainment applications, such as rhythm synchronization, dance/step synchronization in a group, aerobic and other physical exercise related applications.

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： A network device, capable of understanding communications between an end user and the core network on a RAN network is disclosed. In some embodiments, the device is able to decode the control plane and the user plane. As such, it is able to determine when the end user has requested multimedia content. Once this is known, the device can optimize the delivery of that content in several ways. In one embodiment, the device requests the content from the content server (located in the core network) and transmits this content in a just-in-time manner to the end user. In another embodiment, the device automatically changes the encoding and resolution of the content, based on overall monitored network traffic. In another embodiment, the device automatically selects or modifies the format and resolution options based on overall bandwidth limitations, independent of the end user.

摘要： 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).

摘要： A method and system for processing communication at a node in a communication system makes use a series of fixed-length data frames in which multiple data streams are multiplexed. Each of the data streams originates from a corresponding source of data in the communication system, and least two of the data streams originate from a same source of data. For each of the series of fixed-length frames that are processed at a node, multiple offsets within the fixed-length frame are identified, each of these offsets being associated with a different one of the sources of data. The data streams which are multiplexed in the series of fixed-length frames are then processed. For each of the data streams, in each of the series of fixed-length frames, that data stream is processed according to the offset identified for that frame that is associated with the source of that data stream. The approach is applicable to SONET communication in which multiple data streams are multiplexed in a series of synchronous payload envelopes (SPEs), and data encoded in each SPE identifies offsets that characterize displacements, such as row offsets, in the SPE that are each associated with a different source node in the SONET network. An advantage of this approach is that pointer processing scales approximately according to the number of nodes in the system rather than to the number of channels being processed.

摘要： A method and apparatus for using SONET technology to efficiently carry both data and voice traffic by Add/Drop Multiplexing of both isochronous traffic, such as voice and video, and non-isochronous traffic, such as data, in a SONET/SDH fiber-optic ring topology. A portion of a SONET/SDH frame structure (STS-1, STM-1 etc.) is shared by a number of nodes connected to an optical SONET/SDH ring (either directly or sitting behind a SONET/ADM). The inherent column structure of the SONET/SDH frame is used define dynamic channels (flexible bandwidth channels) between the nodes. Each dynamic channel can be assigned a priority and optionally a minimum bandwidth. The channel to column mapping is varied dynamically for data traffic by a centralized bandwidth manager which serves as an arbiter for requests for bandwidth. Both isochronous traffic and best effort data traffic may be carried in an STS-1 frame thereby allowing over-subscribing and statistical multiplexing of data channels over the unassigned portion of the STS-1 frame.
