20120269150 | WIRELESS TERMINAL FOR TRANSMITTING PACKETS OF DIFFERENT TYPES - A terminal comprising: a radio-frequency transmitter for transmitting packets on an uplink to a wireless cellular network; and processing apparatus comprising an upper protocol stack and a lower protocol stack, the upper stack being arranged to process data according to one or more transport protocols and form the data into packets of a plurality of different types for transmission over a packet-based network, and the lower stack being arranged to receive the packets from the upper stack and process them for transmission via the wireless cellular network. The lower stack comprises a plurality of packet queues each corresponding to a different respective priority level, and a packet decoder configured to supply each packet in dependence on its type to a packet queue of a corresponding priority level. The lower stack further comprises a dequeuing mechanism configured to dequeue packets for transmission from said queues in dependence on the priority levels. | 10-25-2012 |
20130089017 | COMMUNICATION SYSTEM AND METHOD - An apparatus comprising a wireless modem for use at a terminal, the modem being adapted to connect to the terminal via a first connection, and to connect via a second, wireless connection to a gateway between a wireless cellular network and a further, packet-based network. The modem is operable to connect to the gateway via the second connection using a point-to-point link protocol that does not require a physical address for the gateway, and is operable to connect to the host terminal via the first connection using a point-to-multipoint link protocol that supports point-to-multipoint connection and does require a physical address for the gateway. The modem is configured to intercept a message being conveyed between the gateway and the terminal, to generate a substitute address that identifies an interface of the modem, and in response to intercepting the message to communicate the substitute address to the terminal. | 04-11-2013 |
20130114503 | Communication System and Method - A unit for use at a terminal as an external wireless modem. In one embodiment, the unit includes: a wireless transceiver for connecting to a gateway between the wireless cellular network and a further, packet-based network; second interface apparatus for connecting to the terminal. The unit further includes processing apparatus arranged to receive a first link layer identifier from the wireless cellular network, gateway or further network, intended for use by the terminal as a source identifier when accessing the further network via the wireless cellular network and gateway. The processing apparatus is configured to intercept at least one message being conveyed from the terminal to the gateway comprising a second link layer identifier generated by the terminal as a source identifier, translate the second identifier into the first link layer identifier and retransmit the message to the gateway with the first link layer identifier as the source identifier. | 05-09-2013 |
20130116008 | COMMUNICATION SYSTEM AND METHOD - A unit for use at a terminal as an external wireless modem. In one embodiment, the unit includes: a wireless transceiver for connecting to a gateway between the wireless cellular network and a further, packet-based network; second interface apparatus for connecting to the terminal. The unit further includes processing apparatus arranged to receive a first link layer identifier from the wireless cellular network, gateway or further network, intended for use by the terminal as a source identifier when accessing the further network via the wireless cellular network and gateway. The processing apparatus is configured to intercept at least one message being conveyed from the terminal to the gateway comprising a second link layer identifier generated by the terminal as a source identifier, translate the second identifier into the first link layer identifier and retransmit the message to the gateway with the first link layer identifier as the source identifier. | 05-09-2013 |
20130148572 | COMMUNICATION SYSTEM AND METHOD - A modem is disclosed that, in one embodiment, includes: first interface apparatus comprising a first wireless transceiver arranged to connect to a wireless cellular network; second interface apparatus arranged to connect to the terminal; and processing apparatus configured as a wireless cellular modem for accessing packet-based communications. The processing apparatus is arranged to receive at least one first address from the wireless cellular network via the first interface apparatus, the first address being an address of a server of a name-to-address resolution system. The processing apparatus is further configured to intercept, via the second interface apparatus, a name-to-address resolution query being conveyed from the terminal to the wireless cellular network comprising a second address as a destination address, to translate the second address into the first address, and to retransmit the query to the wireless cellular network via the first interface apparatus with the first address as the destination address. | 06-13-2013 |
20130176894 | COMMUNICATION SYSTEM AND METHOD - A modem comprising: a wireless transceiver for connecting to a wireless cellular network; second interface apparatus for connecting to a terminal; and processing apparatus which performs operations of a wireless cellular modem to enable the terminal to access a further, packet-based network via access points of the wireless cellular network. The processing apparatus receives a modem command from the terminal, the modem command comprising a field for specifying the name of one of the access points in the form of a text string. The field comprises the names a plurality of the access points and one or more separator characters between them. The processing apparatus is configured to extract each of the names from the field based on the one or more separator characters, and to establish a different respective channel with each of the plurality of access points based on the extracted names. | 07-11-2013 |
20140086288 | SYSTEM AND METHOD FOR INITIATING 3GPP MODEM ONLINE DATA STATES - A modem and a method of placing a modem in an online data state. In one embodiment, the modem includes: (1) a digital interface configured to receive, via an AT channel thereof, a standard AT command directing an AT channel of the modem to exit a command state and enter an online data state and (2) a command processor coupled to the digital interface and configured to: extract channel designation data received as a standard parameter of the standard AT command, cause a channel designated by the channel designation data and separate from the AT channel to enter the online data state, and allow the AT channel to remain in the command state. | 03-27-2014 |
20150015494 | METHOD AND SYSTEM FOR A CREASED PAPER EFFECT ON PAGE LIMITS - In a touchscreen viewing device, a method for implementing a crease effect. The method includes receiving a swipe input related to an image displayed on a touch screen of a viewing device, upon determination that the swipe input will generate an item end effect, causing a crease effect to appear on the image in response to the swipe input, and subsequent to the end of the swipe input, undoing the crease effect on the image to return the image to an original effect. | 01-15-2015 |
