Apparatus may be provided including a spectrum analyzer and decision circuitry. The spectrum analyzer may be configured to ascertain wireless signal signature data from a wide range of frequency bands. The decision circuitry may be configured to modify operation of one or both of a receiver and a transmitter based on the signal signature data.

Multi-band signal detection

A wireless mobile device/station (MS) sends measurement reports of neighbor cells to a serving base transmitter station (BTS). The MS receives information messages transmitted by the BTS at a signaling period, while the MS is in a first cell. The MS is configured to receive a first information message and a subsequent second information message following a handoff. When both information messages are received, the MS transmits a measurement report to the base station, based on contents of the current, received information messages. Responsive to the MS failing to receive/detect the second information message, the MS transmits a measurement report to the BTS based on (a) a current/first information message(s) and (b) a previous information message of the same type as the undetected second information message. The BTS initiates another handoff based on the information in the second type of measurement report.

Expedited reporting of neighbor cell signal strength

A method and apparatus for a customized CLI comprise receiving, by a network element, a first SET-UP message from a transmitting device during a call set up. The network element then retrieves an identification of the transmitting device from the first SET-UP message and obtains a first Caller Line Identification (CLI) of the transmitting device corresponding to the retrieved identification. Further, the network element determines whether the first SET-UP message includes a first indicator and retrieves a data message from the first SET-UP message when the first SET-UP message includes a first indicator. The network element then adds the data message, the first CLI, and a second indicator to a second SET-UP message and transmits the second SET-UP message to a receiving device during the same call set up, for displaying a customized CLI on the receiving device, thereby alerting a user of the receiving device of an incoming call.

A Multiple Protocol Signal Detector, MPSD () has a mixer () that receives signal energy from a multi-band antenna system () via a low noise amplifier () and from a variable frequency synthesizer () via a first variable band pass filter (). The output of the mixer () passes through a second variable band pass filter () to an envelope detector () a power detector () and a low resolution A/D () that inputs digitized samples to a binary modulation detector, BMD (). A controller () configures the aforementioned devices of the MPSD () to detect communications using different protocols based on a scan Look Up Table ().

A wireless communication user terminal having a receiver for receiving a signal having mixed modulation formats, wherein the terminal measures signal power on a portion of the signal received by the terminal, determines a modulation format on the portion of the signal for which the signal power was measured, and modifies the signal power measured based on the modulation format.

A method in a mobile wireless communication device capable of receiving a paging message transmitted in a series of bursts over successive time frames including receiving () not more than one burst of an incoming paging message, determining () whether the incoming paging message corresponds to a known paging message, and () reducing power consumption of radio circuits of the mobile wireless communication device during time frames when other bursts would be received if the incoming paging message corresponds to the known paging message. If the incoming data does not correspond to the known data, additional burst are received and decoded.

A method for a radiotelephone to search for a high priority, home, or home-equivalent public land mobile network (PLMN) includes a first step of registering and camping () the radiotelephone on a cell of visited PLMN. A next step includes uniquely identifying () the cell. A next step includes searching () for PLMNs with a higher priority than the visited PLMN while registered and camped on the uniquely identified cell. A next step includes storing () a history of those frequencies found that are not of a higher priority PLMN for the uniquely identified cell. Any subsequent searches for frequencies of higher priority PLMNs performed while registered and camped on that cell includes scanning () for available frequencies except for those frequencies listed in the history for the uniquely identified cell in which the radiotelephone is registered and camped.

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.

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 () from neighboring cells, and attempting to acquire or otherwise identifying signals from the channels of the neighboring cells () 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 (), 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 (). Where the measured power is substantially comprised of adjacent channel power, the channel is removed from the list of channels to acquire ().
