Patent number: 8964757Abstract: Combining parallel Hypertext Transfer Protocol (HTTP) connections and pipelining overcomes an impact of increasing Round Trip Time (RTT) by varying in real time the number of parallel connections and pipelined requests such that the number of outstanding requests is minimal and the link remains fully utilized. Optimal construction and scheduling of requests and connections in an HTTP stack improves page load time and also provides for greater responsiveness to changes in object priorities. Multi-homing and mobility at the application layer for HTTP are addressed. Multi-homing provides for simultaneous use of multiple interfaces, for example WWAN and WLAN interfaces which improves download time, especially in the case that the available bandwidth the interfaces is of the same order of magnitude. Mobility provides for switching connections as the device moves. In combination they provide for smoother mobility. Mobility can be provided this way without server or network support.Type: GrantFiled: December 10, 2010Date of Patent: February 24, 2015Assignee: QUALCOMM IncorporatedInventors: Mark Watson, Lorenzo Vicisano

Patent number: 8854966Abstract: Methods and apparatus for allocating resources (such as communications bandwidth) using a network access device. In one embodiment, the network includes a wireless network (e.g., WiFi), and the access device includes a wireless router or gateway in communication with a plurality of wireless users. The device includes an administrator function which allows the network administrator to implement one or more resource allocation policies or rules. Using this approach, resources such as bandwidth can be allocated based on any number of different parameters or use classifications, including for example: (i) public versus private use; (ii) security level; (iii) user range from the access device; (iv) type of PHY or air interface; (v) type of channel coding; (vi) air interface mode or application (e.g., data versus voice). In one variant, the allocation policies are manually controlled by the administrator. In another variant, substantially automatic resource allocation is performed by the administrator program.Type: GrantFiled: January 10, 2008Date of Patent: October 7, 2014Assignee: Apple Inc.Inventor: Anthony M.

Patent number: 8855099Abstract: Systems and methodologies are described that facilitate multiple-phase selective connection establishment in wireless communications networks. Radio resource control (RRC) layer communications can be instantiated between a mobile device and base station. Additional information can be required by a downstream network component regarding the mobile device. Accordingly, the RRC resources can be utilized to transmit the additional information from the mobile device to the network component to facilitate the multiple-phase establishment. This can be accomplished using non-access stratum (NAS) messages. Further, the information can relate to authorization, security re-configuration, context re-synchronization, an identity of the mobile device, and the like.Type: GrantFiled: March 6, 2008Date of Patent: October 7, 2014Assignee: QUALCOMM IncorporatedInventors: Masato Kitazoe, Francesco Grilli

Patent number: 8848532Abstract: A data processing method and system and relevant devices are provided to improve the processing efficiency of cores. The method includes: storing received packets in a same stream sequentially; receiving a Get_packet command sent by each core; selecting, according to a preset scheduling rule, packets for being processed by each core among the stored packets; receiving a tag switching command sent by each core, where the tag switching command indicates that the core has finished a current processing stage; and performing tag switching for the packets in First In First Out (FIFO) order, and allocating the packets to a subsequent core according to the Get_packet command sent by the subsequent core after completion of the tag switching, so that the packet processing continues until all processing stages are finished. A data processing system and relevant devices are provided. With the present invention, the processing efficiency of cores may be improved.Type: GrantFiled: April 15, 2011Date of Patent: September 30, 2014Assignee: Huawei Technologies Co., Ltd.Inventors: Lingyun Zhi, Linhan Li, Fei Song, Zuolin Ning

Patent number: 8848531Abstract: Computer-readable media for dynamic quality of service assignment are described. In embodiments, a data packet is received that is part of a communications stream and a dynamically modifiable quality of service indicator (DMQOSI) is embedded into the data packet wherein, in various embodiments, the DMQOSI indicates a prescribed quality of service that is associated with the data packet and is modifiable prior to completing a communication of the communications stream. In various embodiments, the data packet is communicated from a source to a destination that at least periodically references the DMQOSI to ensure that the data packet is being communicated consistent with the prescribed quality of service associated with the data packet.Type: GrantFiled: January 24, 2011Date of Patent: September 30, 2014Assignee: Sprint Communications Company L.P.Inventors: Jeremy R.

Patent number: 8848535Abstract: Systems and methods are described for using opportunistically delayed delivery of content to address sub-optimal bandwidth resource usage in network infrastructures that allow subscribers to share forward link resources. According to some embodiments, content is identified as delayable and assigned to a delaycast queue and/or service flow. For example, a server system of a satellite communications system identifies content that can be delayed to exploit future excess link capacity through multicasting and to exploit subscriber-side storage resources. Some implementations attempt to exploit any excess link resources at any time, while others exploit unused bandwidth only during certain times or when a certain threshold of resources is available. Various embodiments also provide content scoring and/or other prioritization techniques for optimizing exploitation of the delaycast queue.Type: GrantFiled: March 14, 2013Date of Patent: September 30, 2014Assignee: Viasat Inc.Inventors: Mark D.

Patent number: 8837282Abstract: In one embodiment, a method includes obtaining a message associated with a data flow that includes a first indicator that identifies an amount of requested pool bandwidth and a second indicator that identifies a pool with which the data flow is associated. The pool is associated with a plurality of data flows that includes the data flow. The method also includes determining whether the pool has an overall bandwidth allocation, and, if so, determining whether reserving the amount of requested bandwidth would cause the overall bandwidth allocation to exceed a maximum pool bandwidth allocation. Finally, the method includes reserving approximately the amount of requested bandwidth when it is determined that reserving the amount of requested bandwidth would not cause the overall bandwidth allocation to exceed the maximum pool bandwidth allocation. Reserving approximately the amount of requested bandwidth includes increasing the overall bandwidth allocation by the amount of requested bandwidth.Type: GrantFiled: November 8, 2011Date of Patent: September 16, 2014Assignee: Cisco Technology, Inc.Inventors: James M.
