  • Patent number: 8620319
    Abstract: A system and method is disclosed for selectively masking or revealing an availability of mobile voice and data services associated with a mobile device when a handoff frequency from data capable to data-limited networks exceeds a threshold. The system can include components that can detect a network handoff event, compute a handoff frequency and compare the handoff frequency to a threshold. Additional components can mask availability of voice and data services at mobile device based on the comparison. Also disclosed is a method for determining a mobile device location, mapping RF signal quality of data capable networks surrounding the location, and indicating an impending loss of service if the RF signal quality falls below a quality threshold.

  • Patent number: 7580720
    Abstract: Systems and methods for communicating support or absence of support of a plurality of protocol features are disclosed. Generally, a plurality of bits is received, each individual bit indicating support or absence of support of a different protocol features. The received plurality of bits are analyzed to determine which protocol features are supported by a first telecommunications station.

  • Publication number: 20080034075
    Abstract: Systems and methods are provided for offering customer configuration options when selling a cellular communications device. Offering to sell a cellular communications device can be done over the internet or via an in-store kiosk. The customer can configure at least one software configurable feature at the time of purchase, and the phone is delivered with the software preconfigured according to the customer's specification. Alternatively, the customer indicates one or more internal, non removable selections for the desired features of the phone, and the phone is assembled according to the customer's configuration.

  • Patent number: 7209761
    Abstract: A protocol feature communication method and system is disclosed. The method defines a bit stream identifying each feature of a protocol version. Each bit of the bit stream is set in either a first logic state indicating support of the corresponding protocol feature or a second logic state indicating an absence of a support of the corresponding protocol feature. The bit stream is stored within a mobile station. The system comprises the mobile station and base station. The mobile station is operable to transmit the bit stream to the base station and the base station is operable to determine each protocol feature supported by the mobile station by identifying each bit of the bit stream that is set in the first logic state.
