摘要:
A communication system is disclosed in which a mobile terminal having limited power is able to communicate with a land-based network via a low-rate satellite communication link. To achieve VoIP communications via a low-rate link, link-layer assisted zero-header header compression techniques are employed to reduce VoIP packet overheads. Additionally, overheads introduced by link layer protocol layers are eliminated or reduced. A transmitting device strips RTP/UDP/IP header information from a stream of VoIP packets. The transmitting device then sends an initial context message providing the RTP/UDP/IP header information. The stripped zero-header VoIP packets are then transmitted via a satellite relay. A receiving device uses the initial context information to reconstruct the headers for the zero-header VoIP packets.

An install factory creates install packages used to install complex applications onto multiple data processing systems in a reliable and reproducible manner. The install factory takes a variety of inputs to build a custom installation package. The custom install package may be used repeatedly for installs, using the same install package, a full install on a first data processing system, an updated install on a second data processing system, a fix or service pack on a third data processing system, and also configure an application on a fourth data processing system. Thereafter, all data processing systems have the desired level of the application installed. In addition, the install factory may create install packages that are modified in accordance with user preferences.

Adaptive De-Jitter Buffer for Voice over IP (VoIP) for packet switch communications. The de-jitter buffer methods and apparatus presented avoid playback of underflows while balancing end-to-end delay. In one example, the de-jitter buffer is recalculated at the beginning of each talkspurt. In another example, talkspurt packets are compressed upon receipt of all remaining packets.

Aspects relate to a Remote NodeB Relay that appears similar to a NodeB, a Radio Network Controller (RNC), and served mobile devices. Also provided is a Super-Light Router Relay that can provide better performance and QoS to served mobile devices while mitigating modifications to mobile devices, NodeBs, or interfaces between RNC and intermediary NodeBs. Aspects also relate to an Internet Protocol (IP) Relay that requires few, if any, modifications to mobile devices, NodeBs, or interfaces between RNC and intermediary NodeBs. Further, changes to an RNC and/or a core network can be mitigated though utilization of a strategic Relay Gateway.

Aspects of the present disclosure relate generally to wireless communication systems, and more particularly, to estimation of an uplink channel capacity. In an aspect, provided is a method of wireless communication, which may include determining whether a current transmit time interval (TTI) is relevant for computing the uplink channel capacity estimate, determining the transmission type of the current TTI where the current TTI is relevant, determining whether data is transmitted during the current TTI, computing a data capacity value based on at least one upload channel parameter, summing the data capacity values of TTIs from a window length start TTI to the current TTI to generate a data capacity sum, computing the uplink channel capacity estimate as a ratio of the data capacity sum to a total time period of all relevant TTIs during a window length interval, and accordingly adjusting a transmission rate of output traffic.

Methods, apparatus, systems and computer program products are defined that provide for in-order deliver of data packets during hand-off. The aspects provide for in-order delivery at Forward Link Serving eBS/Data Attachment Point (FLSE/DAP) switch and Reverse Link Serving eBS/Data Attachment Point (RLSE/DAP) switch. As such, present aspects provide for significant improvement in the throughput of applications, such as applications relying on Transmission Control Protocol (TCP), during handoff, in such networks as Ultra Mobile Broadband (UMB) and the like.
