摘要： A method and apparatus to quickly adjust a targeted Eb/N0 in a wireless communication system by using an effective Eb/N0 for each frame. The Eb/N0 distribution of a frame produces a certain frame error rate. Effective Eb/N0 is the Eb/N0 that would produce the same frame error rate in a model channel, such as an additive white Gaussian noise (AWGN) channel. The effective Eb/N0 for each frame is obtained and compared to a model targeted Eb/N0. The Eb/N0 for all of the power control groups in one frame compose the vector Eb/N0. The effective Eb/N0 for the frame is obtained by mapping a vector Eb/N0 into a scalar. The model targeted Eb/N0 is the Eb/N0 value that produces a desired frame error rate in the model channel. The targeted Eb/N0 is increased by one up step size when the effective Eb/N0 is smaller than the model targeted Eb/N0 and is decreased by one down step size when the effective Eb/N0 is larger than the model targeted Eb/N0. Eb/N0 are measured for each power control group in a frame. The wireless communication system includes a transmitter to transmit a signal, a receiver to receive the signal, and an outer control loop to adjust the targeted Eb/N0 based on a comparison of the effective Eb/N0 of the signal to the model targeted Eb/N0. Preferably, the outer control loop is implemented in software, although it can be implemented in hardware. Obtaining an effective Eb/N0 for each time period allows quicker adjustments of the targeted Eb/N0. This permits the targeted Eb/N0 to be closer to an Eb/N0 that produces a desired frame error rate, especially if the mobile is moving. This allows the transmitted power to be closer to the power needed to produce the desired frame error rate, permitting an increase in the capacity of the wireless communication system while still maintaining an acceptable number of errors.

摘要： A facility is provided for more efficiently controlling transmitted power in a forward link of CDMA telecommunications system. This is done by offsetting a power reference level that adjusts the level of the transmitted power using an power offset selected as a function of a transmission rate specified for the transmission of a coded frame. The coded frame is then transmitted at a power level selected as function of the adjusted power reference level, rather than the unadjusted level. Such efficiently is particularly noticeable when there is transition from one frame transmission rate to another such rate and vice-versa.

摘要： Provisioning and access control for communication nodes involves assigning identifiers to sets of nodes where the identifiers may be used to control access to restricted access nodes that provide certain services only to certain defined sets of nodes. In some aspects provisioning a node may involve providing a unique identifier for sets of one or more nodes such as restricted access points and access terminals that are authorized to receive service from the restricted access points. Access control may be provided by operation of a restricted access point and/or a network node. In some aspects, provisioning a node involves providing a preferred roaming list for the node. In some aspects, a node may be provisioned with a preferred roaming list through the use of a bootstrap beacon.

摘要： Techniques are described for encoding an audio video stream that is transmitted over a network, for example a wireless or IP network, such that an entire frame of audio and an entire frame of video are transmitted simultaneously within a period required to render the audio video stream frames by an application in a receiver. Aspects of the techniques include receiving audio and video RTP streams and assigning an entire frame of RTP video data to communication channel packets that occupy the same period, or less, as the video frame rate. Also an entire frame of RTP audio data is assigned to communication channel packets that occupy the same period, or less, as the audio frame rate. The video and audio communication channel packets are transmitted simultaneously. Receiving and assigning RTP streams can be performed in a remote station, or a base station.

摘要： In a handover operation an access terminal is handed over from a source access point to a target access point. To facilitate efficient identification of a target access point, a handover operation may be initiated by the target access point. A candidate frequency search also may be invoked to confirm that an access terminal identified by a target access point for a handover is in the vicinity of the target access point. A source access point may verify whether an access terminal is in a vicinity of a target access point to determine whether to perform a handover operation. A source access point may handle potential ambiguity between several target access points by sending handover commands to each of these target access points. An access terminal also may assist in the determination of whether to perform a handover operation.

摘要： The disclosure is directed to a mobile communication device that is capable of accessing different types of networks at the same time. The mobile device registers a public ID with a first IP address over a first access network and also registers the same public ID with a different IP address over a second access network. Additional registrations and IP addresses may occur as well. Of particular benefit is that the different registrations are active during at least some concurrent period of time. This allows a user of the mobile device to have improved continuity of service, select preferred access methods, and receive different data services simultaneously.

摘要： Systems and methodologies are described that facilitate cell search, selection, and reselection within a wireless communication network that includes a home node base station (home nodeB). A user equipment (UE) can detect a home nodeB and communicate such identification to a macro network that includes at least one node base station (nodeB). The detected home nodeB and nodeB can be hierarchically structured in order to prioritize connectivity with the home nodeB over the nodeB. Such prioritization can be implemented by broadcasting home nodeB parameters and macro nodeB parameters having identification information therewith.
