Universal Mobile Telecommunications System (UMTS); Bandwidth And Resource Savings (BARS) and speech enhancements for Circuit Switched (CS) networks (3GPP TR 23.977 version 15.0.0 Release 15)
The objective of this technical report is to identify the full set of requirements for bandwidth and resource savings and
improved speech quality, with specific consideration to networks supporting A/Gb mode and the bearer independent
circuit-switched core network (BICN). The different architectural solutions to meet these requirements will be assessed.
Consideration shall be made to existing architectures and solutions to provide harmony between 2G nodes, UMTS
nodes and external networks (PSTN/ISDN). Backward compatibility to existing solutions and ease of network
introduction/upgrade shall be given high importance.
