Abstract: A method (300) and mobile device (120) for reduced scanning within a uniform period in an out-of-service condition is described herein. In one arrangement, the method can include the steps of detecting (310) the out-of-service condition, during a wake-up interval (410), waking (314) up to scan one or more channels (510, 520, 530, 540) for service and maintaining a constant wake-up time for subsequent wake-up intervals. The method can also include the step of varying (320) the amount of time spent scanning the channels during the subsequent wake-up intervals. As an example, varying the amount of time spent scanning channels can be done by decreasing (322) the amount of time spent scanning for each successive, subsequent wake-up interval.

Abstract: Disclosed is a display system and a method of a display system including a display device configured to provide visual output in a direction, and a camera associated with the display, the camera image collector being pointed in the direction of the visual output, the camera configured to collect facial data. A processor is provided to correlate facial data with content data so that the display will display specific content while the camera collects the facial data. A user's mobile communication device can detect the display system and transmit facial data to the display system. When a user is positioned so that the camera of the system can collect facial data of the user's face, the system can push specific content based upon facial recognition of the user correlated with the user's preferences or other criteria. A determination as to content to display is based upon facial recognition.

The images include at least one icon and at least one image to be used as a background setting for the display screen. The electronic device includes the display, at least one storage device, and a processing unit. The storage device(s) digitally stores the images and operating instructions for displaying the images. The processing device is operable in accordance with the operating instructions to: retrieve the images from the storage device, determine at least one portion of the background setting that is of higher importance than a remainder of the background setting to produce at least one high importance portion of the background setting, and instruct the display to display the background setting and the icons on the display screen such that the high importance portion(s) of the background setting is viewable.

Abstract: A method of operating a communication device to facilitate a user to control multiple concurrent communication sessions. In operation, the communication device receives a plurality of incoming communications from a plurality of recipients, in which each recipient corresponds to at least one of the multiple concurrent communication sessions. The communication device further detects a user response from a user interface of the communication device in response to receiving the incoming communications. Next, the communication device correlates the user response with at least one of the received incoming communications or previously received communications corresponding to the recipients. Further, the communication device selects at least one of the plurality of recipients based on the correlation and sends the user response to the selected at least one of the plurality of recipients.

Abstract: A method and system for retry of a packet data call. The method can include the steps of attempting (210) an IP registration with a mobile unit (110) to make a packet data call using a first protocol on a network (120) that employs both the first protocol and a second protocol for packet data calls and detecting (212) a failure in the IP registration using the first protocol due to a failure in a data link layer of the first protocol. A physical layer of the first protocol is unaffected by the failure in the data link layer of the first protocol such that communications may still be performed over the physical layer. The method can also include the steps of—at the mobile unit—ceasing (214) the attempted IP registration using the first protocol on the network and attempting (216) an IP registration with the mobile unit using the second protocol of the network. As an example, the first protocol can be EVDO, and the second protocol can be 1X.

The method comprises selecting an operating mode of the wireless communication device. If the selected operating mode is a factory safe mode (225), the wireless communication device limits its maximum transmission power to a second value (242). The second value of the maximum transmission power is a value at which the electromagnetically sensitive devices in the electromagnetically sensitive environment are not affected.

Abstract: A mobile station typically determines whether to drop a communication link and/or a base transceiver station (BTS) based on a performance of an associated forward link. In order to avoid dropping a communication link that has a weak forward link but a strong reverse link, a communication system is provided that determines whether the reverse link is still good before determining to drop the communication link. In one embodiment, the communication system determines whether reverse link is still good based on a quality metric associated with the reverse link and quality metric(s) associated with one or more other reverse links that are in a soft-handoff mode with reverse link. In another embodiment, the communication system determines whether reverse link is still good by comparing a quality metric associated with the reverse link to a threshold.

By performing call setup in this manner, mobiles that access with no soft handoff requirement (approximately 50% of mobile in IS-2000 systems) will have faster setup times.

Abstract: Modulation codes for code division multiple access (CDMA) cellular communications systems that are mutually orthogonal may be generated as a sequence of Walsh codes. A method of assigning Walsh codes includes the steps of (404) receiving as input a status vector (200) for a Walsh code system of length 2n and a selected Walsh code length j=2n?k; (406)–(418) creating a new status vector for a selected Walsh code length of j from the status vector; (416) creating a search mask for the selected Walsh code length j; (418) creating a search sequence for the selected Walsh code length j; and (434)–(442) searching the search sequence for the next available Walsh code. The status vector is updated (500) to track the assignment and release of each Walsh code of each Walsh code length in the Walsh code system.

Abstract: After a base station (101) receives a communication initiation request from a remote unit (113), the base station determines (101) those base stations (101–103) that are capable of supporting communication with the remote unit (113). The eligible base stations (Active Set) are instructed to “listen” for communication from the remote unit (113), and the remote unit (113) is provided the Active Set. Once the remote unit (113) receives the Active Set of base stations, the remote unit then determines the base station (103) having the best radio environment characteristics, and begins communication with that base station (103).
