SYSTEMS AND METHODS FOR COMMUNICATING HALF-RATE ENCODED VOICE FRAMES
First Claim
1. A method for communicating half-rate encoded voice frames, the method comprising:
- receiving, by a digital signal processor, a half-rate encoded voice frame;
determining, by the digital signal processor, a network access code;
encoding, by the digital signal processor, a network identifier based on the network access code;
scrambling, by the digital signal processor, the network identifier to generate a scrambled network identifier;
generating, by the digital signal processor, an erasure pattern;
generating, by the digital signal processor, a half-rate embedded voice code word based on the erasure pattern and the half-rate encoded voice frame; and
generating, by the digital signal processor, a half-rate embedded logical data unit based on the half-rate embedded voice code word and the scrambled network identifier.

Abstract
A method for communicating half-rate encoded voice frames. The method includes receiving, by a digital signal processor, a half-rate encoded voice frame. The method further includes determining, by the digital signal processor, a network access code. The method further includes encoding, by the digital signal processor, a network identifier based on the network access code. The method further includes scrambling, by the digital signal processor, the network identifier to generate a scrambled network identifier. The method further includes generating, by the digital signal processor, an erasure pattern. The method further includes generating, by the digital signal processor, a half-rate embedded voice code word based on the erasure pattern and the half-rate encoded voice frame. The method further includes generating, by the digital signal processor, a half-rate embedded logical data unit based on the half-rate embedded voice code word and the scrambled network identifier.
