摘要:
A method and system for selecting a communication network by a wireless communication device (106) includes receiving (310) an identification parameter at the wireless communication device from a communication network which identifies the communication network. Next, the method compares (312) the identification parameter with a list at the wireless communication device to determine (314) service information. The service information identifies the services supported by the communication network. The method further includes comparing (316) the service information with a service-related datum at the wireless communication device that indicates the services desired by the wireless communication device. Lastly, the method includes selecting (318) the communication network for accessing a requested service if the service information matches the service-related datum.

A communication device (100) and method (700) are disclosed for providing temporary communication features, temporary scheduling features, or combinations thereof associated with temporary membership in a private network (101), such as that associated with a hotel (102), resort (103), or cruise ship (105). An association module (209) can register (701) the communication device (100) with the private network (101) as a temporary member device. A private network information retriever (210) can then retrieve (702) one or both of private network directory information (109) and private network scheduling information (110). An integrator (211) can then integrate this information into an address book application (212) or a calendaring application (215) to provide additional functionality for the communication device (100).
摘要:
Disclosed are a device, system and method for multiple mobile communication devices that may be charged according to their relative priority and/or for multiple mobile communication devices that may be charged to a minimum level. The devices may be connected in any order physically, but based upon their relative charging priority the device with the highest priority may receive a charge first. The device with second highest priority may receive a charge second. Their relative priority may be communicated between the devices by wireless communication. In one embodiment, one or more devices may receive a minimum charge to allow operation, before the devices with the highest priorities are fully charged. In regions where electrical utility infrastructures are minimally developed users may share electrical facilities to recharge a plurality of mobile communication devices so that the devices with the highest priority of the grouped devices are fully charged first.
摘要:
A method for facilitating a mobile station to perform a fast handoff in a wireless communication system allows a handoff procedure to be anticipated (by the mobile station, its serving base station, or both) based on historical information regarding prior successful handoff procedures. In operation, the mobile station receives a neighbor list from a serving base station and determines whether a member base station of the neighbor list is a successful target base station based on historical data. If the member base station is not a successful target base station, the mobile station scans the member base station, measures a signal quality associated with the member base station, and sends a measurement report for the member base station when the signal quality meets a standard signal quality threshold. If the member base station is a successful target base station, the mobile station sends the measurement report for the member base station when the measured signal quality meets a lower signal quality threshold.
摘要:
A method is provided for transferring user identities between one CDMA wireless communication device (120) and another in a wireless CDMA communication system (100) having a network system controller (140). The network controller (140) receives an activation command from a wireless communication device (120), the activation command including identification information identifying the activating wireless communication device (404). Next, the network controller determines whether the activating wireless communication device is a transferred identity wireless communication device in response to the identification information (424). The network controller then activates the activating wireless communication device with a transferred identity (436) if the activating wireless communication device is determined to be a transferred identity wireless communication device (424).
摘要:
A method and apparatus is provided for simultaneously accessing a broadcast channel which allows for maintaining registration on the broadcast channel and a second channel. The broadcast channel includes a reverse link access channel for a portable communication device (120) to send registration messages to a base station and the method initially includes the step of determining whether a predetermined event requiring registration of the portable communication device on the broadcast channel has been detected (302, 304, 306). After detecting the predetermined event, it is determined whether the portable communication device is communicating on the second channel (308). If not communicating on the second channel (308), registration on the broadcast channel is accomplished by transmitting a registration message on the reverse link access channel (320). If communicating on the second channel (308), the registration message is transmitted on the broadcast channel asynchronously (340) or, if supported by the base station (110), as a databurst of a packet of information on the second channel (330).
摘要:
When an input digital signal, having a portion with an associated control value, is connected to a digital filter with adaptive compensation, the digital filter with adaptive compensation selects one of a plurality of coefficient scalers (9501, 9601) as directed by a control bus (990). As the input digital signal propagates through the filter, one of a plurality of next coefficient scalers (9502,9602) are selected by the control bus (990). The digital filter with adaptive compensation interleaves in time the coefficients of multiple conventional filters in order to filter each portion of the digital signal according to its associated control value.
摘要:
An electronic device includes an electrical circuitry interface (112) adapted for coupling with an energy source (106), a comparator (138), and a DC-DC converter circuitry (134) having a switch circuit (161) and an energy storage circuit (132). The switch circuit (161) is coupled to the electrical circuitry interface (112) and to the energy storage circuit (132), and is controlled to charge the energy storage circuit (132). A first input (166) of the comparator (138) is coupled to a voltage that varies with a nominal supply voltage of the energy source (106). A second input (168) of the comparator (138) is coupled to a threshold voltage. A comparator output (160) of the comparator (138) is coupled to the switch circuit (161). In operation, the DC-DC converter circuitry (134) charges the energy storage circuit (132) for a certain time period or until the stored voltage is greater then a desired voltage. The DC-DC converter circuitry (134) is controlled to stop charging the energy storage circuit (132) when current demands cause the energy source voltage to exceed a threshold voltage.
