Abstract: Information is received identifying a geographic location of an access point in a radio access network. Access information is assigned and communicated to the access point, and the access information and the geographic location information is communicated to an access terminal. The access terminal identifies the access point as a preferred access point, including its geographic location. The access terminal receives information identifying its own geographic location, and when the access terminal is near the access point, the access point is used to access the network. The access point receives information identifying its geographic location and communicates the geographic location information to a configuration server. The access point receives access information from the configuration server and provides access terminals access to the network using the access information.

Abstract: In a radio access network in which a first access terminal uses a first access point to access the network and a second access terminal uses a second access point to access the network, interference is reduced in communications between the first access terminal and the first access point by adjusting signal power levels of the second access terminal without requiring coordination between the first and second access points.

Abstract: In addition to other aspects disclosed, a data over signaling message that identifies a recipient access terminal is transmitted from a radio network controller to the sector in response to an attempt by an access terminal on a sector of a wireless network to access a service of the wireless network.

Abstract: A device causes at least one access terminal that is configured to transmit datal to a radio node in a sector of a radio access network to alter transmission. While transmission is altered, the device determines a power of a signal received at the radio node, and updates an average value of signal power using the power measured. A device receives, from one or more access terminals that are configured to receive data from a radio node in a sector of a radio access network, a requested rate at which information should be transmitted to each access terminal, receives from the access terminals information about quality of signals received from the radio node, and generates an event if the requested rate and the information about quality of signals fail to satisfy a condition. An access terminal, located in the vicinity of a first radio node configured to transmit data in a sector of a radio access network, measures signal power of pilot signals received by the access terminal.

Abstract: In a radio access network (e.g., a cellular network), a radio receiver is configured with a switch that alternatively couples an antenna and an impedance-matched load to the remainder of the receiver. Sector load, e.g., rise-over-thermal (ROT), is monitored by comparing a first measurement of signal power in a radio receiver (e.g., signal power output by the receiver) when the radio receiver is coupled to an antenna receiving the data traffic with a second measurement of signal power in the radio receiver when the radio receiver is de-coupled from the antenna.

Abstract: In a radio access network, the reverse link rate of an access terminal is controlled and stabilized by determining a number of connections in one or more sectors in which the access terminal has a connection and setting a rate limit based on at least one of the determined number of connections. The number of connections can be determined for each sector in which the access terminal has a connection or for some subset of these sectors. If the number of connections is determined for more than one sector, the radio access network may limit the reverse link rate based on the sector having the greatest number of connections.

Abstract: This description describes examples of performing reverse link power control in a mobile network having a plurality of first modem devices that receive and transmit signals to wireless access terminals (ATs) and a second device in communication with the plurality of first devices. One of the first devices derives a first power control threshold (PCT) value for reverse link power of one of the access terminals (ATs) and the second device derives a second power control threshold (PCT) value for reverse link power of the one of the ATs. The second power control threshold (PCT) value is transmitted using a data traffic path and either the first PCT value or the second PCT value is selected.

Abstract: The description describes examples for performing reverse link power control in a mobile network having a plurality of first modem devices that receive and transmit signals to wireless access terminals (ATs) and a second device in communication with the plurality of first devices. Execution is transitioned between a first and a second loop to control reverse link power of one of the ATs. The transition is based on a state of a connection. The first control loop executes at one of the first devices and the second loop executes at the second device.

Abstract: A facsimile modem transmitter (40) uses pre-fax control signals, such as an answer tone or an FSK (frequency shift keying) modulation signal, to determine a channel spectral shape of the transmission media (14) before transmitting the fax data. The transmitter (40) determines average energy values of the pre-fax signals as a function of frequencies to determine the channel spectral shape. Using the channel spectral shape information, an appropriate transmission shaping filter (64, 66, 68) is chosen for use by the transmitter (40). This achieves better transmit and receive performance by compensating for roll-off on the transmission media (14), or channel, without the need to use specific training signals.

Abstract: An apparatus and method to characterize an input communication signal as being a voice, tone or noise signal is provided. The apparatus and method involve measuring variations of pitch over time from a sampled input signal. A minimum value of Average Magnitude Difference Function (AMDF) over a pitch range and an average variation value of the AMDF over sampled intervals are used to determine whether the signal is a voice signal, a tone or noise. Historical data of these values is maintained in a dual buffer arrangement and is used in the determination of signal type by detecting transitions.

Abstract: An apparatus and method for detecting and characterizing signals in a communication system provides efficient voice, tone, and noise detection which reduces the amount of processing resources consumed and also distributes the processing demand over time. The present invention provides for such efficient voice, tone, and noise detection by applying the Average Magnitude Difference Function (AMDF) over discrete time intervals to evaluate variations in pitch over time, allowing a hypothesis to be made as to whether a signal is a voice, tone, or noise signal. Two novel metrics are computed which characterize the signal as to pitch and variation in pitch. Rule-based logic is applied to detect transitions between the types of signals.
