摘要:
A communication device locates a preferable wireless service provider in a multi-service provider environment using a frequency band search schedule. Initially, the communications device registers with a less preferred service provider in a first frequency band. While remaining registered with the less preferred service provider, the device examines several frequency bands in the order specified by the frequency band search schedule. A frequency band is examined by dividing the frequency band into many sub-bands, and by locating the strongest signal above a threshold within the sub-band being examined. The examination continues until a second frequency band having a more preferred service provider is located. The communication device then registers with the more preferred service provider.

A level of system self-organization in a wireless communication system is provided using a combined design, planning and verification process to determine system organization parameters. The process determines the parameters based on a measured path loss-related characteristic, such as path loss or bit error rate, between base stations and a plurality of regions in a coverage area. For each region, the characteristic is measured to each base station irrespective of the proximity between the region and the base stations. The measured characteristics enable the prediction of signal strength received at the regions of signals transmitted by the base stations independent of the region location. Accordingly, the characteristics can be measured without information correlating the absolute geographic locations of the regions. The resulting unique characterization of the path loss-related information can be used to determine a variety of system organization parameters, such as the number and transmission power of base stations, neighbor lists, sets of base stations that can reuse channels and the identity of base stations, if any, that can be omitted from the system.

A method and apparatus is provided for communicating on a wireless network which offers a selected service. In accordance with the method, a wireless communicator is tuned to a first signaling control channel broadcast by a wireless network. The first channel identifies one or more services provided over that network. This procedure is repeated for successive signaling control channels until a wireless network providing the selected service is identified. Once this has been identified, communication is conducted between the wireless communicator and the network.

A method for communicating on a wireless network includes receiving a mode signal from a network node. The mode signal represents an operational mode of the network node. The operational mode is defined by selecting from among a plurality of services at least one service whose reception over the wireless network is to be suspended or reinstated. Communication between the network node and the wireless network is subsequently conducted by taking into account the received mode signal. The network node may be a wireless communicator such as a cellular telephone or a fixed station device. Alternatively, the network node may be a wireless switch or a cellular base station.

A communication device locates a preferable wireless service provider in a multi-service provider environment using a frequency or frequency band search schedule. Initially, the communication device registers with a less preferred service provider in a first frequency. While remaining registered with the less preferred service provider, the device examines several frequencies in the order specified by the frequency search schedule. The device determines whether the last frequency used by the communication device has a more preferred service provider. If the last frequency used does not have a more preferred service provider, the device examines each of the plurality of frequencies in the predetermined order in the search schedule. The examination continues until another frequency band having a more preferred service provider is located. The communication device then registers with the more preferred service provider.

A method and apparatus for remote spectrum analysis is disclosed. A channel measurement device is configured to receive and measure the radio spectrum in a geographic location during a measurement phase of operation. A microprocessor processes the signals and stores processed data on a storage device. The channel measurement device contains a communications interface to a land line telephone network and/or a cellular telephone network. During a data transfer phase of operation, the channel measurement device sends the processed data to a remote processor via the land line or cellular telephone network. In addition, the remote processor may act as a remote user interface to control the operation of the channel measurement device. In particular, the remote processor may be used to store values for user programmable configuration parameters in a memory of the channel measurement device via the land line or cellular telephone network. In one embodiment, the cellular telephone network interface may include the components necessary for communicating directly with the cellular telephone network. In another embodiment, the cellular telephone network interface is capable of connecting to a cellular telephone for such communication with the cellular telephone network.

A communication device locates a wireless service provider in a multi-service provider environment using a frequency band search schedule. The frequency band search schedule has a first or home band and a several other frequency bands in a predetermined order. The order of the frequency bands may be programmed by the user or by a home service provider over the air. The communication device searches for an acceptable service provider by examining the home band and then the other bands listed in the frequency band search schedule. The bands are examined in the order specified by the frequency band search schedule. An acceptable service provider is identified by comparing the identity of a service provider specified by an identifier received from a band being examined with a list of acceptable service providers.
