Abstract

Subscriber units and base stations of telecommunication systems are equipped with RF to IF (EXA) circuit boards which provide complete flexibility for radio communication. The boards may communicate on any air interface standard (CDMA, TDMA, Bluetooth, 3G cellular, etc.) at any frequency or band of frequencies. Separate, independent forward and reverse channels may be assignment, each having its own air interface and frequency band. When a call is initiated, a set of optimum forward and reverse channels are assigned, taking into account relevant factors such as traffic, subscriber requirements for high speed data, etc., so that the channel assignment is tailored to the current communication needs. Channel assignment is updated as needs change, as other channels become available and at handoff. In a business model, air time on multiple telecommunication systems is sold to subscribers who can use this technology to roam widely. Revenue is also generated from licensing of the EXA circuit boards in subscriber units and in base stations.

Claims

1. A telecommunications method comprising:

selecting a block of radio communication resources including one or more of

frequency band,

time,

geographic space, and

air interface standard;

communicating to a remote receiver information about the selected resources; and

initiating communication in accordance with the selected resources.

2. The method of claim 1 wherein selecting comprises:

selecting optimum resources for a forward channel; and

selecting optimum resources for a reverse channel.

3. A telecommunications system comprising:

a plurality of autonomous telecommunication networks operable to provide two-way telecommunication service for subscriber unit radios within one or more predetermined geographic areas;

a controller configured to select blocks of telecommunication resources including one or more of

frequency band of one or more of the autonomous telecommunication networks,

call time duration of one or more of the autonomous telecommunication networks,

base station radio equipment of one or more of the autonomous telecommunication networks, and

an air interface standard used by one or more of the autonomous telecommunication networks.

4. A telecommunication method comprising:

identifying assignable wireless telecommunication resources of a plurality of wireless telecommunication service providers;

identifying a subscriber requirement for telecommunication resources;

verifying configurable subscriber equipment of the subscriber and configurable service provider equipment of one of the plurality of wireless telecommunication service providers suitable for two-way wireless communication;

allocating at least a portion of the assignable wireless telecommunication resources for use in satisfaction of the subscriber requirement.

5. The method of claim 4 further comprising:

billing at least one of the subscriber and a service provider associated with the at least a portion of the assignable wireless telecommunication resources.

6. The method of claim 4 wherein the assignable wireless telecommunication resources comprise at least one of

frequency band,

time duration of a communication,

geographic space, and

air interface standard.

7. The method of claim 4 wherein verifying comprises:

determining capabilities of the configurable subscriber equipment and configurable service provider equipment; and

identifying a match among the capabilities.

8. The method of claim 7 further comprising:

selecting an optimal transmission channel for a call between the configurable subscriber equipment and configurable service provider equipment; and

selecting an optimal reception channel for the call.
