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. The category of service provider may be identified and displayed on the communication device.

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.

Method for selecting a preferable wireless communications service provider in a multi-service provider environment

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.

Method for categorization of multiple providers in a wireless communications service environment

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 ordered. 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 identify of a service provider specified by an identifier received from a band being examined with a list of acceptable service providers.

Method for selecting a wireless communication service provider in a multi-service provider environment

A mobile station communicates with both a cellular network, by which it is assigned a mobile identification number, and to a cordless cellular base station utilizing the same cellular frequency range and communications protocol. The cordless cellular base station is preferably connected to a public switched telephone network and is assigned a landline number. The cordless cellular base station acts as a conduit between the mobile station and the public switched telephone network. When the mobile station comes within range of a cordless cellular base station, it deregisters automatically from the cellular network and register with the cordless cellular base station. Once the mobile station is communicating with the cordless cellular base station, the cordless cellular base station communicates with the cellular network to instruct the cellular network to route all calls for mobile identification number to the cordless cellular base station's landline number. In addition, all calls placed on the mobile station are sent through the cordless cellular base station to the public switched telephone network. When the mobile station severs contact with the cordless cellular base station, the mobile station registers with the regional cellular base station of the regional cellular network. The cordless cellular base station then sends a network forwarding cancellation message to the cellular network to cancel the forwarding of calls for the mobile station's identification number. Once the mobile station is registered with the regional cell, calls to the mobile stations identification number are directly routed by the cellular network to the mobile station.
