TRANSMISSION OF VOICE IN PACKET SWITCHED NETWORKS

摘要

There is disclosed in a packet switched network a method of encoding speech packets into blocks, each speech packet including a speech header and a payload comprised of a speech frame, wherein at least two speech frames are encoded into a single block. Each speech frame may be associated with a different user. Each speech frame may be associated with the same user. A speech header associated with only one speech frame may be encoded. Each speech frame may be generated by a full-rate encoder. Two speech frames may be encoded into a block without puncturing. Each speech frame may be generated by a half-rate encoder. Four speech frames may be encoded into a block. Each speech frame may include a set of Class I bits and a set of Class II bits, the method further comprising: encoding a first speech frame by encoding at least a portion of the header and the set of Class I bits; encoding a second speech frame by encoding at least a portion of the header and the set of Clas I bits.
