Abstract: A computer-implemented method for inserting an out-of-band signaling packet into a real-time protocol (RTP) stream is provided. The method includes receiving the out-of-band signaling packet intended for transmission to a user device and forming a synthesized packet based on payload information from the out-of-band signaling packet and header information stored in a data structure describing the RTP stream. The method also includes inserting the synthesized packet into the RTP stream. The method further includes receiving an RTP packet intended for transmission to the user device via the RTP stream, analyzing an insertion sequence number and an insertion flag maintained in the data structure, and discarding or forwarding the RTP packet via the RTP stream based on the analyzing.

Abstract: In a system, device, and method for selecting a channel from among a plurality of channels, a number of available channels are selected for testing. A channel quality measurement is made for each of the number of available channels. The channel having the best channel quality measurement is then selected. To make the channel quality measurements, a primary station selects a channel to be tested and also selects a secondary station with which to perform the test. The primary station transmits a control frame to the selected secondary station, including a channel identifier identifying the selected channel. Upon receiving the control frame, the selected secondary station adjusts its transmitter to the selected channel based on the channel identifier in the control frame, and transmits a reference signal on the selected channel. Meanwhile, the primary station adjusts its receiver to the selected channel and receives the reference signal from the selected secondary station.
