Abstract
Abstract A method for secure registration of a access device (400) having a receiver (418) and a transmitter (420) transmitting at an operational RF power level with a base station (200) having a receiver (218) and a transmitter (216) in which the base station reduces its operational RF power level to a registration RF power level and transmits a registration invitation message (610) to an access device (400), wherein the base station (200) after receiving a registration response message (614) from the access device (400) restores its power level to the operational RF power level.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
75 words
A method for registration of a first device having a receiver and a transmitter transmitting at an operational RF power level comprising: reducing the operational RF power level of the first device to a registration RF power level; transmitting a registration invitation message from the first device to a second device; receiving at the first device a registration response message from the second device; and restoring the first device to the operational RF power level.
Claim 2
Independent Claim
75 words
A method for registration of a first device having a receiver and a transmitter transmitting at an operational RF power level comprising: reducing the operational RF power level of the first device to a registration RF power level; transmitting a registration invitation message from the first device to a second device; receiving at the first device a registration response message from the second device; and restoring the first device to the operational RF power level.
Claim 3
Dependent Claim
29 words
A method according to claim 1, wherein the step of reducing the operational RF power level is preceded by a step of activating a switch on the first device.
Claim 4
Dependent Claim
28 words
A method according to claim 1, wherein the step of reducing the operational RF power level is preceded by a step of expiring of a fixed time interval.
Claim 5
Dependent Claim
14 words
A method according to claim 1, wherein the registration response message contains encrypted data.
Claim 6
Dependent Claim
21 words
A method according to claim 1, wherein the first device and the second device are located in an in-home wireless network.
Claim 7
Independent Claim
75 words
A method for registration of a first device having a receiver and a transmitter transmitting at an operational RF power level comprising: receiving a registration request message at the first device from a second device; reducing the operation RF power level of the first device to a registration RF power level; transmitting a registration response message from the first device to the second device; and restoring the first device to the operational RF power level.
Claim 8
Independent Claim
75 words
A method for registration of a first device having a receiver and a transmitter transmitting at an operational RF power level comprising: receiving a registration request message at the first device from a second device; reducing the operation RF power level of the first device to a registration RF power level; transmitting a registration response message from the first device to the second device; and restoring the first device to the operational RF power level.
Claim 9
Dependent Claim
14 words
A method according to claim 6, wherein the registration response message contains encrypted data.
Claim 10
Dependent Claim
21 words
A method according to claim 6, wherein the first device and the second device are located in an in-home wireless network.
Claim 11
Independent Claim
92 words
An apparatus comprising: a transmitter having a transmit power control element switching a power output of the transmitter between a first, relatively high, level and a second, relatively low, level; a first source providing operational signals to the transmitter; a second source providing registration signals to the transmitter; and a controller coupled to the transmit power control element causing the output power to be switched to the first level when operational signals are provided from the first source and to the second level when registration signals are provided from the second source.
Claim 12
Independent Claim
92 words
An apparatus comprising: a transmitter having a transmit power control element switching a power output of the transmitter between a first, relatively high, level and a second, relatively low, level; a first source providing operational signals to the transmitter; a second source providing registration signals to the transmitter; and a controller coupled to the transmit power control element causing the output power to be switched to the first level when operational signals are provided from the first source and to the second level when registration signals are provided from the second source.
Claim 13
Dependent Claim
43 words
An apparatus according to claim 9, further comprising a switch having a first state and a second state, the switch coupled to the second source, wherein the switch in the second state initiates the second source to provide registration signals to the transmitter.
Claim 14
Dependent Claim
35 words
An apparatus according to claim 9, further comprising a timer having a fixed interval, the timer coupled to the second source, wherein the timer initiates the second source to provide registration signals to the transmitter.
Claim 15
Dependent Claim
36 words
An apparatus according to claim 9, further comprising a receiver coupled to the controller wherein the controller is responsive to receiving a registration request, and initiates the second source to provide registration signals to the transmitter.
Claim 16
Dependent Claim
41 words
An apparatus according to claim 9, further comprising a switching means for switching between a first state and a second state, coupled to the second source, wherein the second state causes the second source to provide registration signals to the transmitter.
