Abstract
A method of conformance testing of a secondary station for use in a radio communication system which permits a soft handover process in which the secondary station engages in communication with a plurality of primary stations. The method permits testing the response of the secondary station to power control commands received simultaneously from each of the plurality of primary stations instructing it to adjust its output transmission power. In particular the method enables testing the secondary stations assessment of the reliability of the power control commands received from each primary station which has not been possible previously. The test is performed by transmitting known sequences of power control commands to the secondary station from each of the primary stations then comparing the actual pattern of changes in output transmission power with the expected pattern of changes.

Claim
1. A test method for conformance testing of a secondary station engaging in a soft handover process in which the secondary station simultaneously communicates with at least two primary stations whereby an output transmission power of the secondary station is adjustable in response to power control commands received by the secondary station from each of the at least two primary stations, the test method comprising:', 'receiving a test signal including a sequence of power commands from each primary station of the at least two primary stations;', 'adjusting and monitoring the output transmission power of the secondary station based on the test signals received from the at least two primary stations; and', 'determining whether a function of the output transmission power of the secondary station is within a specified tolerance associated with the secondary station.
2. The test method of claim 1, wherein the function of the output transmission power is a sequence of changes of the output transmission power based on the test signals received from the at least two primary stations.
3. The test method of claim 1, wherein the specified tolerance is a function of the test signals received from the at least two primary stations.
4. The test method of claim 1, wherein the function of the output transmission power is a difference between a first level of the output transmission power prior to receiving the test signals from the at least two primary stations and a second level of the output transmission power subsequent to adjusting and monitoring the output transmission power of the secondary station based on the test signals received from the at least two primary stations.
5. The test method of claim 1, wherein the secondary station uses an estimate of a reliability of test signals received from the at least two primary stations in determining a required change in the output transmission power.
6. The test method of claim 1, wherein the sequence of power control commands in each test signal is pseudo-random.
7. The test method of claim 1, wherein the sequences of power control commands in the test signals are arranged to establish a particular combination of power control commands that occurs a plurality of times during the reception of the test signals by the secondary station.
8. The test method of claim 1, wherein each sequence of power control commands is arranged to establish a sub-sequence of power control commands that occurs a plurality of times during the reception of the test signals by the secondary stations.
9. The test method of claim 1, wherein the secondary station simultaneously receives the test signals from the at least two primary stations
10. A secondary station engaging in a soft handover process in which the secondary station simultaneously communicates with at least two primary stations whereby an output transmission power of the secondary station is adjustable in response to power control commands received by the secondary station from each of the at least two primary stations, the secondary station comprising:', 'a transceiver operable to receive a test signal including a sequence of power commands from each primary station of the at least two primary stations;', 'a power controller in electrical communication with the transceiver, wherein the power controller is operable to adjust the output transmission power based on the test signals received from the at least two primary stations; and', 'a microcontroller in electrical communication with the transceiver and power controller,', 'wherein the microcontroller is operable to monitor an adjustment of the output transmission power by the power controller based on the test signals received from the at least two primary stations, and', 'wherein the microcontroller is further operable to determine whether a function of the output transmission power is within a specified tolerance associated with the secondary station
11. The secondary station of claim 10, wherein the function of the output transmission power is a sequence of changes of the output transmission power based on the test signals received from the at least two primary stations
12. The secondary station of claim 10, wherein the specified tolerance is a function of the test signals received from the at least two primary stations
13. The secondary station of claim 10, wherein the function of the output transmission power is a difference between a first level of the output transmission power prior to receiving the test signals from the at least two primary stations and a second level of the output transmission power subsequent to adjusting and monitoring the output transmission power of the secondary station based on the test signals received from the at least two primary stations
14. The secondary station of claim 10, wherein the microcontroller uses an estimate of a reliability of test signals received from the at least two primary stations in determining a required change in the output transmission power
15. The secondary station of claim 10, wherein the sequence of power control commands in each test signal is pseudo-random
16. The secondary station of claim 10, wherein the sequences of power control commands in the test signals are arranged to establish a particular combination of power control commands that occurs a plurality of times during the reception of the test signals by the secondary stations
17. The secondary station of claim 10, wherein each sequence of power control commands is arranged to establish a sub-sequence of power control commands that occurs a plurality of times during the reception of the test signals by the secondary stations
18. The secondary station of claim 10, wherein the transceiver simultaneously receives the test signals from the at least two primary stations
19. A secondary station engaging in a soft handover process in which the secondary station simultaneously communicates with at least two primary stations whereby an output transmission power of the secondary station is adjustable in response to power control commands received by the secondary station from each of the at least two primary stations, the secondary station comprising:', 'means for receiving a test signal including a sequence of power commands from each primary station of the at least two primary stations;', 'means for adjusting and monitoring the output transmission power of the secondary station based on the test signals received from the at least two primary stations; and', 'means for determining whether a function of the output transmission power of the secondary station is within a specified tolerance associated with the secondary station.']
