Abstract: Method and system for registration of licensed modules in mobile devices. The present invention provides for a registration system to determine active use of licensed modules installed in mobile devices such as wireless cellular terminals and PDA's. The registration system can be made to operate in a manner that is substantially transparent to the user of the mobile device. In example embodiments, a module handler within the processor platform of the mobile device collects module parameters as necessary and causes registration messages to be assembled and sent. In some embodiments, encryption is provided. User interaction with the registration process can also optionally be accommodated. Additionally, the module handler can direct that use of the software module or package is restricted until an acknowledgement is returned from the module activation system, confirming the registration.

Abstract: A mobile terminal may include a wireless modem, a wireless network interface, and an application (such as a browser application). A method of operating the mobile terminal may include providing a first data path between a data network and the application of the mobile terminal through the wireless modem. In addition, a second data path may be provided between the data network and second mobile terminal through the wireless modem and the wireless network interface of the first mobile terminal. Related devices are also discussed.

Abstract: A system and method of operating a mobile phone accessory communicable with a mobile phone. The present invention dynamically loads software into a mobile phone from a mobile phone accessory to enable better management of the accessory's resources and capabilities. After a communication link is established between the mobile phone and mobile phone accessory, both devices exchange information to determine the appropriate software to transfer. A verification process then ensures that the mobile phone and mobile phone accessory are authorized to receive and transfer software, respectively. Subsequently, software is transferred from the mobile phone accessory to be stored in the mobile phone. The mobile phone is capable of executing the downloaded software. Specifically, the mobile phone contains the necessary API(s) and processor hardware needed to run a variety of software.

Abstract: Selected identifiers belonging to the wireless communications device are provided to a network entity based upon the control function being processed, or more generally, upon the class of control function being processed. In one embodiment, a Mobile Switching Center (MSC) receives a plurality of identifiers and a control function request from a wireless communications device. The MSC determines which of the identifiers are needed by the network entity to process the requested control function based on the control function requested. The MSC filters the received identifiers to remove un-needed identifiers based on its analysis and forwards the filtered identifiers to the network entity and/or to another network. In another embodiment, the present invention pushes the determination of which identifier to send downward to the wireless communications device itself.

Abstract: A method and apparatus for performing over-the-air activation for wireless communications service subscriptions within a wireless communications system. The method includes providing a plurality of subscription modules each having a unique identifier that corresponds to a plurality of non-activated service subscriptions. An activation period is established for each of the non-activated service subscriptions within which the corresponding subscriptions must be activated or deleted from the system. A list of unique identifiers and their associated activation periods is stored in the wireless communications system. To activate the subscription, a subscription module is mated with a mobile equipment device. An over-the-air activation request is transmitted to the wireless communications system that includes the unique identifier associated with said selected subscription module.

Abstract: A method of controlling the transmission of identities for wireless communications devices relies on a broadcast message from the network to instruct the wireless communications devices as to when to send their identity information. The network's control over the transmissions is extended to the control function class level. In a simple embodiment, the network includes instructions in a broadcast message telling the receiving wireless communications devices to send their identities for some classes of control functions and not others. Thus, by altering the broadcast message, the network is able to control the identity transmissions of the wireless communications devices. In more sophisticated embodiments, the network can control not only whether identities are transmitted for certain control functions, but which identity is transmitted. Thus, one identity (e.g., subscription module identifier) may be transmitted with one class of control functions (e.g., registration) and another identity (e.g.

Abstract: In a mobile station used in a cellular mobile telecommunication system that communicates on any one of a plurality of base station cellular channels depending on cell location of the mobile station, the system being adapted to selectively determine one of the channels to process a call with the mobile station and handoff a cellular call with the mobile station from a current channel to a new channel, a handoff system for detecting system and capability changes when a handoff has occurred. The handoff system includes a memory storing data representing parameters associated with the current channel. A forward communication channel is associated with the current channel for receiving data from a base station. The data includes a handoff message if a handoff is to occur. The handoff message includes parameters associated with the new channel.

Abstract: A method and system used in a wireless network that provides communication service on both analog control channels (ACCs) and digital control channels (DCCHs) controls access to wireless services by a mobile station. The method comprises the steps of acquiring wireless services on a select ACC; periodically receiving a pointer to a preferred DCCH as part of a message received from the wireless network via the ACC; initially attempting to acquire wireless service on the preferred DCCH, including determining if received signal strength is acceptable and available service features are acceptable, and if not, then indicating the preferred DCCH as rejected; storing information on the rejected DCCH; and subsequently attempting to acquire wireless service on the rejected DCCH only if the DCCH was rejected due to received signal strength not being acceptable.

Abstract: A method for responding to a pointer received on an analog control channel pointing to a control channel belonging to a forbidden service provider includes avoiding a power-up scan and resuming camping on the analog control channel. A wireless communications mobile unit is camped on an analog control channel may receive a channel pointer to a digital control channel. If the digital control channel has acceptable received signal strength, the service provider information for that control channel is checked. If the control channel belongs to a non-forbidden service provider, the mobile unit camps on the digital control channel. If the control channel belongs to a forbidden service provider, the mobile unit returns to camping on the analog control channel without performing an intervening power-up scan. By avoiding power-up scans when the pointed-to channel belongs to a forbidden service provider, less power is consumed and users receive more consistent communications service.

Abstract: An integrated circuit for driving a sensor includes an oscillator for providing a first clock signal synchronized to a periodic waveform supplied by an external source. A second clock signal in the form of a uni-polar square wave is derived from the first clock signal. A sinewave signal is generated by consecutively selecting voltage steps from a resistor ladder under control of the second clock signal. A low-pass filter removes from the sinewave signal higher frequency harmonics generated by switching through the steps of the resistor ladder. A linear amplifier utilizes an external capacitor to couple the filtered sinewave signal to the sensor. Temperature compensation is provided by comparing the voltage of the sinewave signal supplied to the sensor with an external temperature stable reference voltage. The integrated circuit also includes circuitry for amplitude demodulating a signal returned from the sensor to provide a sensor output signal.
