1 A QCOM Circuit Video TSG-A TITLE: Circuit Switched Video Telephony (SO s, ) Support for the next revision of the IOS SOURCE: Sanjeev Athalye QUALCOMM, Incorporated David Ott QUALCOMM, Incorporated () sathalye@qualcomm.com () 0 dott@qualcomm.com ABSTRACT: Video Telephony (video conferencing) is a feature that operators are interested in. Service Options ( kbps video conferencing) and ( kbps video conferencing) have been defined in TSG-C (see TIA-9). This contribution proposes IOS changes to enable support for Service Options and in the IOS. Change marks are relative to IOS v. v.0 text. The changes add descriptive text to the Overview section of the IOS Features document. In the A/A/A document, the Service Options are added to messages that use the Service Option IE and Service Option List IEs. RECOMMENDATION: Accept for the next revision of the IOS.

Refer to [] for details on the service options ( and ). Service Option is used for a data rate of kbps and Service Option is used for a data rate of kbps. According to [], RLP is terminated in the SDU. A Rate Adaptation function at the BSC adapts the rate above RLP to the fixed rate of the terrestrial bearer for traffic flowing from the MS to the

The A interface carries data between the Rate Adaptation function at the BSC and the MSC. Normal call origination, call termination, and call clearing procedures apply. Call flows associated with this feature are described in sections..,.., and.. This standard supports handoffs for Circuit Switched Video Conferencing calls as indicated in section...
