Abstract
Abstract A system and method for providing automatic system deregistration for any incorrectly registered radios is described. The system and method further provides for an automatic re-registration request to be sent in order to guarantee that any valid radios that have the same radio identification information in the system as the incorrectly registered radio to become re-registered. By requesting any radio having the same ID to re-register back with the system, a loss of communication to that radio is thereby prevented.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
135 words
A method for deregistering a communication device which has incorrectly registered in a communication system, the communication system having a plurality of communication devices each having device identification information operating within the communication system, the plurality of communication devices having registered with the communication system, the method comprising the steps of: determining at one of the plurality of communication devices that the communication device has incorrectly registered with the communication system: receiving a deregistration message from the communication device which incorrectly registered with the communication system; deregistering the incorrectly registered communication device from the communication system; and requesting that any from among the plurality of communication devices operating in the communication system which has the same device identification information as the communication device which incorrectly registered on the system to re-register with the communication system.
Claim 2
Independent Claim
135 words
A method for deregistering a communication device which has incorrectly registered in a communication system, the communication system having a plurality of communication devices each having device identification information operating within the communication system, the plurality of communication devices having registered with the communication system, the method comprising the steps of: determining at one of the plurality of communication devices that the communication device has incorrectly registered with the communication system: receiving a deregistration message from the communication device which incorrectly registered with the communication system; deregistering the incorrectly registered communication device from the communication system; and requesting that any from among the plurality of communication devices operating in the communication system which has the same device identification information as the communication device which incorrectly registered on the system to re-register with the communication system.
Claim 3
Dependent Claim
38 words
The method of claim 1, comprising the further step of: preventing the communication device which incorrectly registered with the communication system to re-register with the communication system after the communication device has been deregistered from the communication system.
Claim 4
Dependent Claim
22 words
The method of claim 1, wherein the communication system is a trunked radio communication system and the communication devices are trunked radios.
Claim 5
Dependent Claim
19 words
The method of claim 1, wherein the communication system is cellular system and the communication devices are cellular telephones.
Claim 6
Dependent Claim
35 words
The method of claim 1, wherein the deregistration message sent by the incorrectly registered communication device includes the communication device's unique identification number and an information field informing the communication system of the incorrect registration.
Claim 7
Dependent Claim
24 words
The method of claim 5, wherein the step of requesting any communication device to re-register on the system is performed by a system controller.
Claim 8
Dependent Claim
120 words
A radio communication system for use by a plurality of radios, each of the radios having radio identification information and the plurality of radios have registered with the communication system, one from among the plurality of radios in the communication system is incorrectly registered with the communication system and has transmitted a deregistration message, the radio communication system comprising: means for receiving the deregistration message sent from the radio that incorrectly registered with the radio communication system; and means for requesting that any from among the plurality of radios that belongs in the radio communication system and that has the same radio identification information as the radio that incorrectly registered with the radio communication system to re-register with the system.
Claim 9
Dependent Claim
120 words
A radio communication system for use by a plurality of radios, each of the radios having radio identification information and the plurality of radios have registered with the communication system, one from among the plurality of radios in the communication system is incorrectly registered with the communication system and has transmitted a deregistration message, the radio communication system comprising: means for receiving the deregistration message sent from the radio that incorrectly registered with the radio communication system; and means for requesting that any from among the plurality of radios that belongs in the radio communication system and that has the same radio identification information as the radio that incorrectly registered with the radio communication system to re-register with the system.
Claim 10
Dependent Claim
24 words
The radio communication system of claim 7, wherein the radio communication system is a trunked radio communication system and the radios are trunked radios.
Claim 11
Dependent Claim
22 words
The radio communication system of claim 7, wherein the radio communication system is a cellular system and the radios are cellular telephones.
Claim 12
Dependent Claim
41 words
The radio communication system of claim 7, wherein the automatically requesting means comprises a system control means that transmits a re-register packet to all the radios in the radio communication system upon receiving the deregistration information from the incorrectly registered radio.
Claim 13
Dependent Claim
37 words
The radio communication system of claim 10, wherein the deregistration message sent by the incorrectly registered communication device includes the communication device's unique identification number and an information field informing the communication system of the incorrect registration.
