Abstract

A trunked communication system utilizes information on mobile unit location provided by a mobile unit to provide prioritized communication system availability. By further utilizing location information, the trunked communication system also provides a current communication system as a highest priority communication system as a mobile unit moves into a non-receiving area within an area served by the current communication system.

Claims

1. A communication network prioritization system for use with a mobile unit having a memory means for storing an inventory of at least a first available communication system, comprising:

A) location determining means for at least approximately determining location of the mobile unit within a particular location; and

B) discriminating means responsive to the location determining means for providing a prioritized inventory of peripheral communication systems available closely proximate to the particular location;

such that the discriminating means selectively provides at least one valid closely proximate available communication system as a function, at least in part, of the location of the mobile unit.

2. A communication network prioritization system for use with a mobile unit having a memory means for storing an inventory of at least a first available communication system, comprising:

A) location determining means for at least approximately determining location of the mobile unit within a particular location; and

B) discriminating means responsive to the location determining means for providing current communication system as a highest priority communication system available to mobile unit entering non-receiving area peripheral to the particular location;

such that the discriminating means selectively provides current communication system as a function, at least in part, of the location of the mobile unit.

3. A communication network prioritization system for use with a mobile unit having a memory means for storing an inventory of at least a first available communication system, comprising:

A) location determining means for at least approximately determining location of the mobile unit within a particular location; and

B) discriminating means responsive to the location determining means for providing current communication system as a highest priority communication system available to mobile unit entering peripheral receiving area closely proximate to the particular location;

such that the discriminating means selectively provides current communication system as a function, at least in part, of the location of the mobile unit.

4. A method for prioritization of communication systems available to a mobile unit having a memory means for storing an inventory of at least a first available communication system, comprising the steps of:

A) determining at least approximately a location information of a mobile unit within a particular location;

B) communicating the location information to a resource controller; and

C) sending a location prioritized list of valid available closely proximate communication systems closely proximate to the particular location to the mobile unit by the resource controller;

wherein the prioritized list of valid available closely proximate communication systems is a function, at least in part, of the location of the mobile unit.

5. A method for prioritization of communication systems available to a mobile unit, comprising the steps of:

A) determining at least approximately a location information of a mobile unit within a particular location;

B) communicating the location information to a resource controller; and

C) providing current communication system as a highest priority communication available to the mobile unit;

wherein the mobile unit is entering a non-receiving area closely proximate to the particular location and the provision of the current communication system is a function, at least in part, of the location of the mobile unit.

6. A method for prioritization of communication systems available to a mobile unit having a memory means for storing an inventory of at least a first available communication system, comprising the steps of:

A) determining at least approximately a location information of a mobile unit within a particular location;

B) communicating the location information to a resource controller; and

C) providing current communication system as a highest priority communication available to the mobile unit;

wherein the mobile unit is entering a peripheral receiving area closely proximate to the particular location and the provision of the current communication system is a function, at least in part, of the location of the mobile unit.
