Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
62 words
A method for registering a direct mode mobile station with a system controller of a trunked radio system by an independent gateway transceiver comprising the step of: selecting an available gateway transceiver by the direct mode mobile station; and registering the mobile station with the system controller of the trunked radio system by the gateway transceiver using a third party registration scheme.
Claim 2
Independent Claim
62 words
A method for registering a direct mode mobile station with a system controller of a trunked radio system by an independent gateway transceiver comprising the step of: selecting an available gateway transceiver by the direct mode mobile station; and registering the mobile station with the system controller of the trunked radio system by the gateway transceiver using a third party registration scheme.
Claim 3
Dependent Claim
67 words
The method of claim 1 wherein the step of selecting comprises the steps of: searching for an available gateway transceiver to register the mobile station with the system controller of the trunked radio system; and acknowledging from an available gateway transceiver to the mobile station that the gateway transceiver is available to register the direct mode mobile station with the system controller of the trunked radio system.
Claim 4
Dependent Claim
60 words
The method of claim 2 wherein the step of searching for an available gateway transceiver comprises the step of: transmitting a gateway transceiver search message from the mobile station to at least one gateway transceiver in an attempt to find an available gateway transceiver to register the direct mode mobile station with the system controller of the trunked radio system.
Claim 5
Dependent Claim
29 words
The method of claim 3 wherein the step of transmitting the gateway transceiver search message includes transmitting an address of the mobile and an address of the gateway transceiver.
Claim 6
Dependent Claim
45 words
The method of claim 2 wherein the step of acknowledging comprises the step of: transmitting a gateway transceiver acknowledgement message from a gateway transceiver; and receiving a gateway transceiver acknowledgement message at the mobile station from the gateway transceiver indicating status of the gateway transceiver.
Claim 7
Dependent Claim
42 words
The method of claim 5 wherein the step of acknowledging further comprises the step of: transmitting a confirmation message from the mobile station to the gateway transceiver to indicate to the gateway transceiver to transmit a registration message to the system controller.
Claim 8
Independent Claim
97 words
The method of any preceding claim wherein the step of registering the mobile station with the system controller of the trunked radio system by the gateway transceiver comprises the steps of: transmitting a third party registration demand from the gateway transceiver to the system controller to demand registration of the mobile station; transmitting a registration reply from the system controller to the gateway transceiver; and transmitting a registration status by the gateway transceiver to the mobile station thereby confirming registration of the mobile station with the system controller of the trunked radio system by the gateway transceiver.
Claim 9
Independent Claim
48 words
The method of any preceding claim wherein the step of registering the mobile station with the system controller of the trunked radio system by the gateway transceiver comprises the step of: authenticating the mobile station by the system controller to verify if mobile station is a valid user.
Claim 10
Independent Claim
22 words
The method of any preceding claim further comprising the step of terminating registration of the mobile station initiated by the gateway transceiver.
Claim 11
Dependent Claim
79 words
The method of claim 9 wherein the step of terminating registration of the mobile station initiated by the gateway transceiver comprises the steps of: transmitting a third party de-registration demand by the gateway transceiver to the system controller; receiving a third party de-registration reply from the system controller at the gateway transceiver; transmitting a gateway transceiver detach message from the gateway transceiver to the mobile station; and receiving a detach acknowledgement by the mobile station at the gateway transceiver.
Claim 12
Independent Claim
27 words
The method of any one of claims 1 to 8 further comprising the step of terminating the registration of the mobile station initiated by the mobile station.
Claim 13
Dependent Claim
78 words
The method of claim 11 wherein the step of terminating registration of the mobile station initiated by the mobile station comprises the steps of: receiving a terminate message at the gateway transceiver from the mobile station; transmitting a termination acknowledgement message from the gateway transreceiver to the mobile station; transmitting a third party de-registration demand from the gateway transceiver to the system controller; and transmitting a third party de-registration reply from the system controller to the gateway transceiver.
Claim 14
Dependent Claim
24 words
The method of claim 1 to 8 further comprising the step of terminating the registration of the mobile station initiated by the system controller.
Claim 15
Dependent Claim
81 words
The method of claim 13 wherein the step of terminating the registration of the mobile station initiated by the system controller comprises the steps of: receiving a third party de-registration demand from the system controller at the gateway transceiver; transmitting a third party de-registration reply message from the gateway transceiver to the system controller; transmitting a gateway transceiver detach message from the gateway transceiver to the mobile station; and receiving a detach acknowledge at the gateway transceiver from the mobile station.
Claim 16
Independent Claim
35 words
A method for registering a direct mode mobile station with a system controller of a trunked radio system by an independent gateway transceiver substantially as herein described with reference to FIG. 3 of the drawing.
Claim 17
Independent Claim
35 words
A method for registering a direct mode mobile station with a system controller of a trunked radio system by an independent gateway transceiver substantially as herein described with reference to FIG. 3 of the drawing.
