  • Patent number: 8422431
    Abstract: Apparatus, and an associated method, for identifying availability of services in a radio network of a radio communication system. A system information message is generated at the radio access network that identifies the service availability of the radio network, such as by indicating the communication services supported by the network. The system information message, once generated, is communicated upon a broadcast control channel, or other appropriate channel, and delivered to a mobile node. The mobile node detects the system information message and determines the availability of services of the radio network therefrom. Selection of whether to register with the network is made responsive to whether the network supports the communication service that the mobile node intends to initiate.

  • Patent number: 7912025
    Abstract: A radio modem includes a serial interface adapted for connection to a host device via a wired serial link; a router coupled to the serial interface; a server coupled to the router; and RF transceiver coupled to the router. The router is configured receive data packets from the host device; identify whether an IP address of the packets match an IP address of the server; identify whether a cookie which identifies the predetermined type of protocol is contained in a cookie field of the packets; in response to identifying a mismatch between the IP addresses, or that the cookie is not contained in the cookie field, cause the packets to be routed to a server via the attachment with the cellular network; and in response to identifying a match between the IP addresses, cause the packets to be routed to the server.

  • Publication number: 20100110926
    Abstract: A radio modem device includes a serial interface adapted for connection to a host device via a wired serial link with use of a PPP connection; a radio modem router coupled to the serial interface; a radio modem server coupled to the radio modem router; and RF transceiver processing circuitry coupled to the radio modem router. The RF transceiver to processing circuitry is configured to provide communications over a wireless link with a cellular network, establish a packet data service attachment with the cellular network, monitor RSSI information during the communications, and maintain an attachment state of the attachment during the communications.

  • Patent number: 7646757
    Abstract: In one illustrative example, a radio modem device includes a serial interface adapted for connection to a host device via a wired serial link with use of a Point-to-Point Protocol (PPP) connection; a radio modem router coupled to the serial interface; a radio modem server coupled to the radio modem router; and radio frequency (RF) transceiver processing circuitry coupled to the radio modem router. The RF transceiver processing circuitry is configured to provide communications over a wireless link with a cellular network, establish a packet data service attachment with the cellular network, and maintain an attachment state of the attachment during operation of the radio modem device.

  • Patent number: 7346028
    Abstract: A radio modem method of processing commands from a host device during a data communication session between the host device and a server connected to the network includes the steps of maintaining a Point-to-Point Protocol (PPP) connection between the host device and the radio modem device; communicating, over a wireless link with a cellular telecommunications network, data packets of an IP connection maintained between the host device and the server; and while the PPP and the IP connections are being maintained: removing a PPP wrapper of the data packets to reveal a destination IP address; identifying whether the destination IP address matches an IP address of a radio modem server of the radio modem device; in response to identifying a match between the IP addresses, causing the data packets to be routed to the radio modem server and processing and responding to the host device in accordance with a command in the data packets at the radio modem server; and in response to identifying a mismatch between the IP a

  • Publication number: 20040121793
    Abstract: Methods and apparatus for controlling power to electrical circuitry of a wireless communication device having a Subscriber Identity Module (SIM) interface are described. In one illustrative embodiment, a method includes the acts of receiving a power down signal from a user interface of the wireless communication device; powering down radio frequency (RF) transceiver circuitry of the wireless communication device in response to the power down signal; and maintaining power to a SIM interface of the wireless communication device while the RF transceiver circuitry is powered down from the power down signal. A visual display of the device is capable of displaying information (e.g. address book information) from a SIM card while the RF transceiver circuitry is powered down from the power down signal.
