In one aspect, embodiments of the present disclosure include a distributed proxy and cache system, including, a local proxy on a mobile device for intercepting a data request made via a mobile device, and a proxy server coupled to the mobile device and a content server to which the data request is directed. In one embodiment, the local proxy can forward the data request to the proxy server for transmission to the content server for a response to the data request. In addition, the proxy server sends the data request to the content server independent of activities on the local proxy and notifies the local proxy when changed or different content on the content server is detected for the data request. | 2012-07-12 |

20120176970 | METHODS AND SYSTEMS FOR IMPLEMENTING INTER-NETWORK ROAM, QUERYING AND ATTACHING NETWORK - Methods and systems are disclosed for implementing inter-network roam and for querying and network attachment, applied in a network of access identifier and location identifier separation, wherein the method for implementing inter-network roam comprises: after attaching to an ASN of a roaming area network, a roaming terminal sending a first data packet whose destination address is the AID of a destination device to the destination device; after receiving the first data packet, the ASN querying locally AID-RID mapping information, and requesting a roaming gateway to query the RID of the destination device if the RID is not found and the destination device does not belong to the roaming network; the roaming gateway querying the RID from a home network of the destination device and returning to the ASN; according to the RID, the ASN sending subsequent data packets of the roaming terminal to the destination device. | 2012-07-12 |
20120176971 | METHOD AND APPARATUS FOR SUPPORTING SEGMENTATION OF PACKETS FOR UPLINK TRANSMISSION - A method and apparatus for segmenting medium access control (MAC) service data units (SDUs) creates enhanced MAC-es PDUs in the enhanced MAC-e/es sub-layer by concatenating MAC SDUs received from the logical channels. An enhanced transport format combination (E-TFC) selection entity controls the concatenation of MAC SDUs into enhanced MAC-es PDUs. When a MAC SDU is received that is too large to fit into a selected enhanced MAC-es PDU payload, a segmentation entity segments the MAC SDU such that the MAC SDU segment fills the remaining payload available in the selected enhanced MAC-es PDU. The enhanced MAC-es PDU is then assigned a transmission sequence number (TSN) and multiplexed with other enhanced MAC-es PDUs to create a single enhanced MAC-e PDU that is transmitted on the E-DCH in the next transmission time interval (TTI). A HARQ entity stores and, if necessary retransmits the enhanced MAC-e PDU when a transmission error occurs. | 2012-07-12 |
20120176972 | Method and System for Establishing Wireless IP Connectivity - A method and system for establishing wireless IP connectivity, in which a wireless communication device (WCD) obtains a routable IP address during its registration with a radio access network, rather than first registering with the RAN and then subsequently requesting and acquiring packet-data connectivity. Preferably, when the WCD sends a radio access registration request that triggers a registration notification to a home location register (HLR), the HLR or an associated entity will assign an IP address for use by the WCD and will deliver the assigned IP address in a registration notification response message to the RAN. The RAN will then deliver the assigned IP address to the WCD over the air in a radio access registration response message. The WCD may then use the assigned IP address to engage in packet data communications, such as to set up a VoIP session with another IP node, for instance. | 2012-07-12 |
20120176973 | METHOD FOR PROCESSING MULTIPLE ACCESS, HOME AGENT AND USER EQUIPMENT - A method for processing multiple access, a home agent and user equipment are disclosed in the present invention. The method includes the following steps: when a user equipment establishes a mobile internet protocol version 6 (MIPV6) security association with a home agent, the home agent sends first indication information to the user equipment, wherein the first indication information is used to indicate to the user equipment that the home agent is able to support multi-registration flow binding. The present invention can improve the system efficiency. | 2012-07-12 |
20120176974 | NETWORK SETUP IN WIDE CHANNEL WIRELESS LOCAL AREA NETWORKS (WLANs) - Methods and apparatus for network setup in wide channel WLANs are provided. Techniques for co-existence of 20 MHz and 40 MHz networks (e.g., as defined by IEEE 802.11n) may be extended to 80 MHz and 160 MHz networks. For example, a primary channel of an existing network may be designated as the primary channel of a new network. Further, a primary channel of the existing network may not be used as a secondary channel in the new network. Intolerance operation between networks may include a first network releasing one or more channels in response to an intolerance indication received from a second network. Furthermore, in response to the intolerance indication from the second network, the first network may utilize one or more channels for communicating in the first network using a first set of access parameters. The access parameters may depend on the intolerance indication. | 2012-07-12 |
