Voice quality optimization on multi-codec calls

A communication network having multiple codecs communicating voice calls between an originating network and a terminating network. The communication network includes an originating codec and a terminating codec. The network provides signaling indicating the decoding algorithm to the originating network, and indicating the encoding algorithm to the terminating network. The original encoding algorithms and the original decoding algorithms are then altered from the standard as a function of this signaling to produce a best fit encoding matching to improve voice quality.

Implementing ain concepts in an existing switching system

Ericssons Traffic Management System (TMS) embodies the basic principles and much of the functionality of the future widespread implementation of an advanced Intelligent Network (AIN). TMS introduces AIN concepts into the existing telephony network, thus giving service providers an immediate revenue-enhancing tool as well as a real-world proving ground for AIN principles. The first TMS release begins commercial service in 1990.
