This document contains a preliminary response from TSG-S4 to the TSG-SA and TSG-T2 request to all 3GPP Working Groups to identify the Terminal Implementation Capabilities linked with their area of expertise.
The Terminal Capabilities are listed in the following table (to be completed) for each Service Capability involving the Codec Working Group (TSG-S4). The table first lists any capability to be mandatory supported by any 3G Terminal supporting the related Service Capability, then the optional capabilities identified by the specifications. When necessary, the right column lists some network capabilities linked to the Terminal Capabilities under review.
