Abstract:
PROBLEM TO BE SOLVED: To provide an apparatus and method for reducing the power consumption of a battery of a mobile station when during in between roamings between a WAN 105 and a WLAN. SOLUTION: An access point (AP) 111 of the WLAN is synchronized with the WAN 105. The mobile station 101 transmits a beacon to the WLAN during a prescribed time window. Further, the AP 111 of the WLAN detecting the beacon from the mobile station 101 communicates with the WAN 105, through backhaul connections 113, 117 to inform the WAN 105 that the mobile station 101 has been detected. Thereafter, the WAN 105 transmits a message to the section 101, starts searching the AP of the WLAN, and hands over the mobile station from the WAN 105 to the access point of the WLAN.

PROBLEM TO BE SOLVED: To provide an apparatus and method for reducing the power consumption of a battery of a mobile station, when during in between roamings between a WAN 105 and a WLAN. SOLUTION: An access point (AP) 111 of the WLAN is synchronized with the WAN 105. The mobile station 101 transmits a beacon to the WLAN during a prescribed time window. The mobile station 101 recognizes the time window and throws in power of a WLAN transceiver unit, only for during the corresponding window. Since the AP 111 of the WLAN is synchronized with the WAN 105, the mobile station 101 can predict the corresponding time window and apply power. When the mobile station 101 detects the beacon from the AP 111 of the WLAN, the mobile station 101 informs the WAN 105 about it through a BTS 107 of the WAN, and hands over idle mode signaling from the BTS 107 in charge to the AP 111 of the WLAN.

Abstract:
PROBLEM TO BE SOLVED: To shorten a hand-off time by a mobile unit always monitoring signal intensity of base stations, sorting signals in order of intensity and also aligning both frames of a desired control channel SCH and a traffic channel TCH. SOLUTION: In normal communication start, a control circuit 203 of a mobile unit monitors a list of control channel frequencies that are received by a receiver 227, measures the signal intensity of an allocation BA frequency and sorts signals in order of intensity. Next, when traffic channel TCH frames and desired control channel SCH frames are aligned, a base station identification code BSIC is decoded. When they are not aligned, they are aligned with the next SCH frames, a bit error rate or frame error rate of a receiving signal is monitored and increased, a voice is suspended when communication is suspended, the code BSIC of a cell of the highest signal intensity is decoded, and hand-off is requested and executed.
Abstract:
A method includes providing a cable (125) or component having a first type of connector (121, 123) attached thereto. A device (100) is provided having at least one second type of connector (105, 107), capable of mating with the first type of connector, attached thereto.

Abstract:
A method in a communication network entity, for example, a push-to-talk/anything server, for content sharing in a group communication session including obtaining (210) participant information from a plurality of group participants, determining (220) common group information based on the group participant information obtained, and sending (230) the common group information to the group participants, wherein the group participants format content based on the common group information before communicating content to other participants of the group session.
Abstract:
A method and apparatus dynamically assigns each of a plurality of different information streams associated with one wireless communication unit (12a), to independent communication resources from different communication resource pools from each of a plurality of different wireless network elements (14a-14n), based on, for example, quality of service requirement data determined for each of the information streams. As such, the wireless communication unit (12a) may establish two or more separate links using two or more completely independent radio resources from different wireless base stations in the same system.
Abstract:
The present invention is a method of coordinating an activity at a destination includes receiving a first signal indicative of a first location of a first party (110). The first signal is received at a destination of the first party. A second signal indicative of a second location of a second party is received at a destination (112), which is also the destination of the second party. A schedule is created (150) to coordinate the activity automatically at the destination. The schedule is based on the first and second signals indicative of the first and second locations and may include additional functions such as the estimated times of arrival of the first and second parties (120, 122). Also, the present invention is a method of notification upon arrival at a predetermined location (200) that includes receiving a first signal indicative of the location of a first party (210). A second signal is transmitted to a second party (230) when the location of the first party is equal to a first predetermined location (220). The activity is coordinated at a second location based on the second signal.
Abstract:
A handheld electronic device (100) includes at least one context sensing circuit and a microprocessor (204), and a user interface (212). The sensing circuit detects (205) either a contextual characteristic of the device (e.g., ambient light, motion of the device or proximity to or contact another object) or how the user is holding the device and generates a virtual output (207) representative of the sensed characteristic. The sensed contextual characteristic is associated with a data management function of the device and a virtual physical representation to be output in response to the execution of the data management function is determined. The virtual physical representation is related to the sensed contextual characteristic or the data management function. The virtual physical representation is output by a user interface of the device.
Abstract:
A communication system and a method of communicating data. A first backhaul site (120) can be dynamically selected from a plurality of backhaul sites that are each configured to wirelessly communicate with an access point (115). A controller (225, 315) can dynamically configure a transmission parameter used to communicate a first backhaul data stream (155, 455) between the access point and the first backhaul site. The first backhaul data stream can be derived from a source data stream (150, 450) and can be wirelessly communicated between the access point and the first backhaul site. A second backhaul site (125) also can be selected. A second backhaul data stream (160, 460) also can be derived from the source data stream and wirelessly communicated between the access point and the second backhaul site. The first and second backhaul data streams can be combined.

A system [100] includes a base station [105] to communicate wireless data with at least one user terminal [125, 130] within a cell serviced by the base station [105]. A central backhaul access point [135] communicates wireless backhaul data with the base station [105]. At least a first portion of the wireless data and a second portion of the wireless backhaul data is communicated via Spatial Division Multiple Access ("SDMA"), and the first portion of the wireless data utilizes at least some same time-frequency resources as the second portion of the wireless backhaul data.
