A method for mobile call testing is provided. The method involves initiating at a test-control module a test call to a mobile unit, and detecting at a ring-detecting module, via a contactless coupling to the mobile unit, whether the mobile unit rings in response to the test call from the test-control module. Further, the method then involves providing a ring indication from the ring-detecting module to the test-control module when a mobile ring is detected in response to the test call. In one example, the contactless coupling is an acoustic coupling.

Method and system for mobile call testing using contactless ring detection

A portable interference-generating device for inducing desired frame error characteristics, such as desired frame error patterns and rates, at a mobile unit receiving a carrier signal having at least one data channel having a plurality of data frames. The induced frame errors may be used to test a digital radio receiver's behavior in the presence of frame errors that may occur as a result of various impairments in a CDMA wireless communication channel. The portable interference-generating device includes a noise source that provides a noise signal and a pulse generator that is used to gate the noise signal according to a desired frame error characteristic at the mobile unit. The gated noise signal is provided to the mobile unit via a coupling element, which preferably couples the gated noise signal directly to an antenna radiation element on the mobile unit.

Inducing desired frame error patterns and rates in a CDMA wireless communication channel. The induced frame errors may be used to test a digital radio receiver's behavior in the presence of frame errors. Preferred methods include providing a carrier signal having at least one data channel, where the data channel has a plurality of data frames; generating discrete noise bursts of radio frequency noise, where the noise bursts have a duration characteristic and an interval characteristic; and, combining the noise bursts and the carrier signal to induce a desired frame error characteristic.

Pulse interference testing in a CDMA communication system

A method and system for determining spurious emission output by a wireless terminal. A test set may adjust the transmit power setting of the wireless terminal to a first transmit power setting and then to a second transmit power setting. At the first transmit power setting and then at the second transmit power setting, the wireless terminal may transmit a signal over a spread spectrum channel. Also, at the first transmit power setting and then at the second transmit power setting, a spectrum analyzer may measure actual power of the signal transmitted by the wireless terminal. Spurious emission output by the wireless terminal may be characterized as any signals transmitted by the wireless terminal outside of the spread spectrum channel.
