A method of operating a communication system is disclosed. The method includes transmitting from a remote unit to a base station remote unit channel data. The remote unit channel is generated at the remote unit and includes data about a first portion of communication channels on which the call can be executed. The method also includes applying a channel selection method to the remote unit channel data and to base station channel data so as to select a communication channel from among the first portion of communication channels. The base station channel data is generated at the base station and includes data about a second portion of the communication channels. The method further includes executing a call on the selected communication channel.

Controlling use of a mobile network element is disclosed. An indication is received that a mobile station associated with a mobile network is attempting to access the mobile network via a base transceiver station that (1) the mobile station is not authorized to use and (2) is located within a geographic area from which the mobile station is authorized to access the mobile network. The mobile station is prevented from accessing the mobile network via the base transceiver station.

Systems and methods are described for segregating airlink resources in a wireless communication network by traffic type. When voice data and traffic data are sent simultaneously in a wireless network using a limited set of frequency resources, the data traffic can cause unacceptable interference in the voice traffic. Accordingly, transceivers share their voice traffic and data traffic demands and may allocate portions of an airlink resource into resource zones for exclusive use by voice traffic and data traffic. Within each resource zone, the transmission can be optimally managed for each traffic type, and interference between voice traffic and data traffic is reduced.

A networked computing system facilitating ancillary device measurement of regional network communications in order to determine intra-network communications handovers. The networked computing system includes a base station, one or more transceiver devices having shorter-range communications capability than the base station, user equipment, and a data communications network facilitating data communications amongst the networked computing systems devices. Within the network, a first transceiver device may be configured to detect ancillary communications between a user equipment and the base station, and then measure one or more characteristics associated with the ancillary communications in response to detecting the ancillary communications. The first transceiver device may also be configured to transmit the measured characteristics to the base station or to an auxiliary network controller device that is capable of making network communications usage decisions based on one or more network resource usage rules.

A method is provided for minimizing the peak power level in a combination of orthogonal frequency division multiplexed (OFDM) tones. The method is particularly effective when the information to be communicated is digital data consisting of long patterns of “1”s or “0”s. The digital data of the message is combined with a scrambling vector before the data is modulated. The randomization of data patterns, in turn, leads to a more random combination of OFDM tone amplitude being transmitted. The message is recovered at the receiver by removing the scrambling vector. A table of scrambling vectors is maintained at the transmitters and receivers. The table pointer to select the scrambling vector is selected in response to the position of the message in the communication structure. An OFDM communication system using the above-described method is also provided.

A method and an apparatus provide for controlled access to a shared communication medium. Time slots on a forward channel include information regarding status useful for remote units to determine whether a reverse channel is available for seizure. Additionally, information along the forward channel provides guidance to the remote units to control attempts to seize the reverse channel. In one embodiment a remote unit divides a data package into a plurality of portions and attempts to seize the reverse channel using a single portion of the data package which corresponds to one time slot on the reverse channel. It then waits until it receives notification along the forward channel that the first data portion was successfully received before it attempts to send any of the remainder of its data in consecutive time slots on the reverse channel.
摘要:
In a discrete tone system, a base station receives a transmission burst from a remote unit being installed that includes delay compensation pilot tones that are uniformly spread throughout the transmission bandwidth. The arrival time transmission burst is not synchronized with the other remote units transmitting to the base station. The base station measures the phase delay of each tone and calculates the delay of the remote unit from the slope of the line of phase angle versus tone frequency. The base station transmits a signal to the remote unit that includes the magnitude and direction of the delay, which allows the remote unit to adapt the timing of its transmission to be synchronized with the other remote units.

Facilitating use of a restricted base transceiver station is disclosed. To a first set of subscribers associated with a mobile network operator, access to a mobile network is provided via base transceiver stations associated with a first mobile network identifier associated with the mobile network operator but not via base transceiver stations associated with a second mobile network identifier associated with the mobile network operator. To each of a second set of subscribers associated with the mobile network operator, access to the mobile network is provided via a corresponding subset of a set of base transceiver stations associated with the second mobile network identifier, the subset including for each subscriber in the second set one or more base transceiver stations with respect to which that subscriber is an authorized user.
