摘要： The present invention provides methods of inter-technology handoff of a multi-mode mobile unit in a packet-switched communication system. One embodiment of the method includes establishing a call from a first application layer client in the first mobile unit using a first wireless communication link that operates according to a first wireless access technology. The method also includes sending, in response to detecting changing conditions of the first wireless communication link, a request to form a conference call including the first application layer client and inviting a second application layer client in the first mobile unit to join the conference call. The second application layer client uses a second wireless communication link that operates according to a second wireless access technology. The method further includes handing off the call from the first application layer client to the second application layer client.

摘要： The input (and output) power of a multi-carrier amplifier can be controlled to allow the amplifier to operate at high RF power levels and still remain within a power rating profile. The amplifier (or amplifiers) power is controlled using an aggregate scaling factor. The aggregate scaling factor is generated from a plurality of amplifier scaling factors. Each amplifier scaling factor is generated based on a comparison of a time-averaged total power and a corresponding threshold.

摘要： A method of wireless communication. The method includes the step of broadcasting a message, such as channel list message, for example. The broadcasting message lists each available carrier for each available frequency band in the wireless communication spectrum—e.g., 400 MHz and about 2100 MHz. Each available carrier listed within the message may correspond with at least one cell of a coverage area. Moreover, each broadcast message comprises at least one occurrence for each available carrier. Each available carrier may also be repeated within the message a number of times corresponding to a carrier weighting. This carrier weighting in turn corresponds with a traffic load. Alternatively, the method may also include the step of repeating the broadcast of the message a number of times, wherein the number corresponds to a carrier weighting associated with the traffic load. The broadcast message may also comprise a listing of at least one service, such as voice and/or data, supported by each available carrier.

The method comprises integrating access to the at least one location-based service substantially simultaneously with an offering of at least one multi-media service for voice and data over the wireless network. The method further comprises initiating the at least one location-based service in response to receiving an inquiry from the originating party for determining a network location of a target mobile terminal associated with the destination party.

摘要： When an overload condition is determined to exist at a base station in a wireless communications system based on the number of unsuccessful access attempts to access the system relative to the successful access attempts to access the system, the base station broadcasts a message to each mobile terminal within its coverage area that changes at least one access probe-related parameter associated with at least one of: the number, the frequency, and the power intensity of the access probes made by these mobile terminals as they attempt to establish access to the wireless network. By so limiting these access probes in some manner when an overload condition is present, the interference caused on the reverse link by many mobile terminals attempting access is reduced.

摘要： The number of Reverse Activity Bits (RABs) equal to “1” per frame is a Congestion Overload (CO) metric used to determine whether the reverse link in a wireless communications system is in a congestion overload state due to a reverse link RF overload. When the value of the CO metric exceeds a first predetermined threshold that is indicative of a congestion overload condition, the system enters a block state where all new connection requests are blocked. Once in the block state, if the value of the CO metric does not decrease but continues to increase and exceeds a second higher threshold, the system enters a mute state. In the mute state a predetermined large percentage of existing active calls are muted. Specifically, a message is sent downlink to specific ATs instructing them to reduce their transmission rates to zero but to still maintain their active connections.
摘要翻译：每帧相当于“1”的反向活动位数（RAB）是拥塞过载（CO）度量，用于确定由于反向链路RF过载，无线通信系统中的反向链路是否处于拥塞过载状态。当CO度量的值超过指示拥塞过载状况的第一预定阈值时，系统进入阻塞所有新连接请求的阻塞状态。一旦处于阻塞状态，如果CO度量的值不降低但是继续增加并超过第二高阈值，则系统进入静音状态。在静音状态下，预定的大部分现有活动呼叫被静音。特别地，向特定AT发送下行链路的消息，指示它们将它们的传输速率降低到零，但仍然保持其活动连接。

摘要： A method for determining rise over thermal for a base station in a wireless communications system is provided. The method comprises receiving a first and second diversity signal, measuring the signal strength of the first and second diversity signals, and estimating the noise floor for the first and second diversity signals. The signal strength rise is determined for the first and second diversity signals based on the measured signal strength and estimated noise floor of the first and second diversity signals respectively. The rise over thermal is then determined based on the determined signal strength rise of the first and second diversity signals.
