Abstract: The invention provides an apparatus and method for service access for a mobile communication device. The apparatus can include an identity module for storing user information in the mobile communication device. The identity module can include an identity module frame, a secure storage memory coupled to the frame, the secure storage memory including a mobile communication device subscriber identity and the user information, and an identity module controller coupled to the secure storage memory and the frame, the identity module controller configured to block access to the user information and grant access to the mobile communication device subscriber identity when the identity module enters a blocked mode. The identity module controller may grant access to the mobile communication device subscriber identity in response to a request for a service access communication.

Abstract: The present invention provides a method and apparatus for reducing scanning times by eliminating from consideration channels where the measured power is substantially comprised of adjacent channel power. The method and apparatus include measuring the received channel power (302) from neighboring cells, and attempting to acquire or otherwise identifying signals from the channels of the neighboring cells (306) in descending order of a sorted list of received channel power. When a signal from the channel of a neighboring cell is successfully acquired or otherwise identified, an amount of adjacent channel power is determined (310), based upon an expected power profile of the acquired or otherwise identified signal. The determined adjacent channel power is then compared against the power measured for the corresponding channel (312). Where the measured power is substantially comprised of adjacent channel power, the channel is removed from the list of channels to acquire (316).

Abstract: An apparatus and method for eliminating interference caused by spurious signals in communication signals communicated via a communication device on any one of a plurality of different channels, the communication device operating at a rate set by a system clock signal. The system clock frequency is generated at a first frequency, the first frequency generating spurious signals on at least one of the different channels. The system clock frequency is toggled by a first predetermined amount to a second frequency when the communication device is to be tuned to one of the different channels so as to remove the spurious signals from the tuned channel. The communication device is tuned to the at least one of the different channels. A return of the timing error to a predetermined value is synchronized at a start of a receive data capture event.

Abstract: A method and apparatus for service access for a mobile communication device. The method can include entering a blocked mode of the mobile communication device, sending an emergency service access call identifier identifying an emergency service communication request to a home service center, and sending mobile communication subscriber identification information. The mobile communication device does not need to be registered on the mobile communication network. The method can also include accessing the subscriber identification information on a blocked subscriber identity module, the subscriber identity module located on the mobile communication device. Also, when the subscriber identity module is blocked, the subscriber identity module can block access to user information and allow access to the subscriber identification information for the emergency service communication.

Abstract: A system and method of establishing a network connection for a mobile communication device in a mobile communication network. The method can include receiving an emergency service call identifier from an unregistered mobile communication device, the emergency service call identifier identifying an emergency service request to a home service center, and routing the emergency service request to the home service center. The emergency service call identifier can include a subscriber identification. The method can also include sending a short message service message to the mobile communication device. The short message service message can include an unblock code.

Abstract: A method of and apparatus for optimizing a minimum turn around time (MTAT) between (a) a reception by a first device of a first infrared data communication (IRDC) frame sent from a second device and (b) a transmission by the first device of a second IRDC frame to the second device. The MTAT value received from the second device is loaded into a storage device. The first IRDC frame from the second device is received, and a counter of the first device either resets upon reception of each of the plurality of characters of the first IRDC frame or increments when none of the plurality of characters are received. The first device transmits the second IRDC frame to the second device when the counter value reaches the MTAT value.

Abstract: A wireless communication apparatus (100) and communication method provides an audio-based call connection operation. For example, one method includes receiving an incoming call message (108) and receiving an input audio answer signal (120), such as a user's voice, in response to the incoming call message (108). This method includes detecting an amplitude or characteristic of the input audio answer signal (120) and sending an answer call message (126) based on the detected amplitude level of the input audio answer signal (120). In another embodiment, the process includes storing the input audio answer signal (120) as preconnection audio information (304b) and subsequently sending the preconnection audio information (304b) as a post connection greeting. For example, a user saying the word “hello,” completes the call without any additional greeting required.

Abstract: In a mobile station (MS) of a cellular radiotelephone system, a method of searching for the MS's home public land mobile network (HPLMN) when the MS is camped on a non-HPLMN. The method is performed in thirty second intervals while the MS is already in its receive ready (higher current-drawing) state. The method performs strategic measurements of the receive signal level in order to determine if it is likely that the HPLMN has become available again. If the probability is high that the HPLMN has become available, further data is gathered on the likely available channel. Once the channel is identified, the MS begins the camping procedure to register on the HPLMN.
