Abstract: An apparatus and method for updating the firmware version in a network node is described. The firmware is divided into a plurality of blobs, each blob having an associated blob version. Each blob version is associated with a firmware version. The method includes receiving notification from a client server network node of an updated version of a first blob and the compatible versions of the remaining blobs. A blob upgrade order is determined from the first blob updated version, the remaining blobs compatible versions, and the remaining blobs current versions. Each blob is upgraded in the blob upgrade order. The client is restarted after each blob upgrade.

Abstract: In one embodiment the modem has a network interface, application interface, processor, and memory. The network interface exchanges radio data with a network. The application (or host) interface exchanges application data with an application (or host) processor. The processor converts a unit of radio data to a corresponding unit of application data. The memory stores each unit of application data received by the modem. The processor is configured to execute a selective discard function to reduce traffic by determining if a newly arrived unit of application data is a duplicate of a stored unit of application. In the case that the newly arrived unit of application data is a duplicate of the stored unit of application data, the processor is further configured to selectively discard the duplicate unit of application data in dependence on whether an acknowledgement of the data has been already recognized by the processor.

Abstract: A communication interface and method for efficient robust header compression (RoHC). One embodiment of the communication interface includes: (1) a data flow associated with a context ID (CID) and a data flow status indicator, and having packets, and (2) a robust header compression (RoHC) compressor configured to employ the CID to compress headers of the packets and to mark the CID as reusable by another data flow if the data flow status indicator indicates the data flow is terminated.

Abstract: 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.

Abstract: A modem is disclosed, one embodiment including: first and second interface apparatuses; and a processing apparatus arranged to transmit a request message to part of a wireless cellular network to request establishment of a channel to access a packet-based network, wherein the request message requests the channel as being of a type that supports both a first and second version of a packet protocol; receive a response message indicating rejection of the request, and upon detecting that a field in the response message defines a reason other than the part of the wireless cellular network does not support first and second versions of the packet protocol on a single channel, to default to transmit a default request message to request establishment of a channel to access the packet-based network, the default request message requests the channel as being of a type that supports the first version of the packet protocol.

Abstract: 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.

Abstract: 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.
