| 20080268815 | Authentication Process for Access to Secure Networks or Services - A system (and a method) are disclosed to access to secured services that are located behind a firewall. In one embodiment, the system receives at an authentication server a request to access the secured services. The request includes an identification of a mobile telephony device. The system transmits the identification of a mobile telephony device to a mobile telephone network server. The mobile telephone network server generates and transmits at least one security challenge that is forwarded to the mobile telephony device. In response, the mobile telephony device generates at least one response to the at least one security challenge, which gets forwarded to the mobile telephone network server. The mobile telephone network server notifies the authentication server if the response has been appropriately verified, and if so, the system allows the authentication server to allow access to the secured services, e.g., through an authenticated session. | 10-30-2008 |
| 20090006703 | INTERFACE FOR MULTIPLE MODEMS - Techniques are disclosed involving the exchange of information with multiple modems. For instance, an apparatus includes a host device, a plurality of modems, and a serial connection to transfer information between the host device and the plurality of modems. The information may include data associated with one or more user applications and commands for the plurality of modems. The serial connection may be a Universal Serial Bus (USB) connection. | 01-01-2009 |
| 20090046696 | DTMF SIGNALING IN WIRELESS COMMUNICATIONS NETWORKS - Techniques for transmitting DTMF symbols in wireless communications networks are disclosed. For instance, an apparatus may include a dual-tone multi-frequency (DTMF) messaging module and a transceiver. The DTMF messaging module generates a layer 3 (L3) DTMF message that represents two or more DTMF digits. The transceiver sends the DTMF message across a wireless communications network, such as a GSM network or a UMTS network. In addition, the transceiver receives, from the wireless communications network, an acknowledgment of the DTMF message. This acknowledgment is a DTMF-specific L3 signaling message. | 02-19-2009 |
| 20090054070 | Apparatus and Method for Extending the Coverage Area of a Licensed Wireless Communication System Using an Unlicensed Wireless Communication System - A system includes a network controller to communicate with a telecommunications network. The network controller is coupled to one or more unlicensed wireless base stations serving one or more unlicensed wireless access areas. Each unlicensed wireless access area is mapped to one or more licensed wireless access areas. The system includes a mobile station to communicate with the telecommunications network using a licensed wireless communication channel serviced by the telecommunications network in a licensed wireless access area, and an unlicensed wireless communication channel in an unlicensed wireless access area. The mobile station is associated with a licensed wireless network identifier and a licensed wireless location identifier when the mobile station is in the licensed wireless access area and is associated with an unlicensed wireless network identifier and an unlicensed wireless location identifier when the mobile station is in the unlicensed wireless access area. | 02-26-2009 |
| 20090143078 | TECHNIQUES TO MANAGE A RADIO BASED ON LOCATION INFORMATION - Techniques to manage a radio based on location information are described. A mobile computing device may include a radio module, a location detector operative to determine a location for the mobile computing device, and a processor to couple to the radio module and the resource database. The processor may be operative to execute a resource management module to access a resource profile having resource information for one or more cellular radiotelephone network resources accessible from the location, and control operations for a radio module based on the resource profile. Other embodiments are described and claimed. | 06-04-2009 |
| 20090156253 | Apparatus and Methods for Providing Fully Qualified Domain Name Resolution for Home Network Realm Based on International Mobile Subscriber Identity - Various embodiments for providing fully qualified domain name (FDQN) resolution for a home network realm based on an International Mobile Subscriber Identity (IMSI) are described. In one embodiment, a mobile computing device may be arranged to retrieve an IMSI including a Mobile Country Code (MCC) and a Mobile Network Code (MNC) and to derive an initial FQDN from the IMSI using an initial MNC rule. The mobile computing device may transmit an initial domain name system (DNS) request comprising the initial FQDN. The mobile computing device may be arranged to derive an alternate FQDN from the IMSI using an alternate MNC rule and to transmit a subsequent DNS request comprising the alternate FQDN when a DNS error message is received in response to the initial DNS request. Other embodiments are described and claimed. | 06-18-2009 |
| 20090219205 | APPARATUS AND METHODS FOR MAINTAINING A RELIABLE TIME CLOCK ON A MOBILE COMPUTING DEVICE SUPPORTING SATELLITE BASED POSITION DETERMINATION CAPABILITY - Various embodiments for maintaining a reliable time clock on a mobile computing device are described. In one embodiment, a mobile computing device may optionally enable and disable acquisition of time data from multiple sources including a mobile network and a global positioning system (GPS) satellite. The mobile computing device may comprise a time clock to display local time information derived from stored time data and may prioritize the multiple sources for writing and overwriting the stored time data to converge to the most reliable time data available. Other embodiments are described and claimed. | 09-03-2009 |
| 20090323572 | Intelligent access point scanning with self-learning capability - A method and apparatus for intelligent access point scanning with self-learning capability enables a wireless handset to conserve power while scanning for unlicensed mobile access. | 12-31-2009 |
| 20110070900 | Methods and apparatus for virtually connected communication modes - Methods and apparatus enabling a wireless network to implement efficient and robust paging channel operation. In one aspect, the invention permits recovery of a paging channel after a virtual connection failure. A virtually connected UMTS cellular phone that misses a paging notification will no longer be synchronized with its serving radio network, and the resultant loss of synchronization causes a service “blackout” until the devices are resynchronized. Accordingly, in one embodiment, a virtually connected cellular device continuously monitors for fallback messaging, greatly expediting detection and correction of a virtual connection failure. In another embodiment, a virtually connected base station which is unable to page a cellular device in a virtually connected mode continues paging in both virtual connection and fallback modes, thereby provoking an immediate response from the cellular device. | 03-24-2011 |
