A method and apparatus for transmitting signaling messages over the
communication channel to a CDMA mobile station. If a one-half,
one-quarter, or one-eighth frame voice packet is to be transmitted,
augmenting that packet with signaling information to form, essentially, a
full rate frame; if no more than N consecutive full rate frames are
detected, deferring transmission of the signaling message, and
thereafter, if another full frame voice frame is detected, substituting a
frame of signaling information for the full frame voice frame.
Advantageously, using this arrangement, most short signaling messages can
be transmitted to a CDMA mobile station with minimal voice impairment.
