Advantages
Compatibility of productions now in use (GSM)
R99 System is divided to CS and PS domains
Guarantee of the QoS of RT services
Many experiences on mature technique TDM
Problems R99 does not accord with NGN
Inconvenient to upgrade to R4,R5

WCDMA R4 Characters
The evolution to all-IP step by step in WCDMA network
The main difference happens in CS Domain; in PS, it is all the same
The separation of control and Bearer: MSC to MGW&MSC Server
IP transfer of Signal: SG was introduced

TFO & TrFO
Concept
TFO: Tandem Free Operation: negotiate rate through i
n-band signal, insert a transcoder to support speech be
tween two ends with different codec or voice rates.
TrFO: Transcoder Free Operation: through out-band si
gnal negotiation, it realizes calls that have no transcod
ers involved in the connection between the source cod
ecs
Advantage of TrFO
Improve the quality of speech
