ITU-T H.248.20-2013 网关控制协议:ITU-T H.221和ITU-T H.223复用本地和远程描述符使用研究组16

Recommendation ITU-T H.248.20 defines how the Local and Remote Descriptors are used within ITU-T H.248,ITU-T H.221 and ITU-T H.223 multiplexing (MUX) terminations to associate demultiplexed streams (logical channels) with ITU-T H.248.1 streams.This revision incorporates updates the allowed media values to align with the latest version of the Session Description Protocol (SDP).

ITU-T H.248.40-2013 网关控制协议:应用程序数据不活动检测包研究组16

Recommendation ITU-T H.248.40 describes the principle used to detect application data inactivity for IP transport connections in general,like e.g.,avoid a potential situation of deadlock if latching was set but no application data stream is incoming to latch on. The solution is based on an event to detect if application data had stopped (or not started).This revision provides additional information regarding the setting of the detection time for the IP flow stop event.

ITU-T H.248.19-2013 网关控制协议:分解的多点控制单元音频视频和数据会议软件包研究组16

Recommendation ITU-T H.248.19 describes the functionality of a decomposed multipoint control unit,in particular the interface between a media controller and media processor which is based on Recommendation ITU-T H.248.1.This Recommendation contains guidelines for the use of a decomposed gateway that may support audio,video and data conferencing.This Recommendation contains packages for floor control,volume control,video windows,audio and video mixing for point-to-point,multi-cast and hybrid conferencing scenarios.This revision incorporates corrections to fix a duplicated binary Release Event identity and a duplicated Result parameter binary identity.

ITU-T H.248.1-2013 网关控制协议:版本3研究组16

To achieve greater scalability,this Recommendation decomposes the ITU-T H.323 Gateway function defined in Recommendation ITU-T H.246 into functional subcomponents and specifies the protocols these components use to communicate.This allows implementations of ITU-T H.323 gateways to be highly scalable and encourages leverage of widely deployed Switched Circuit Network (SCN) capabilities such as SS7 switches.This also enables ITU-T H.323 gateways to be composed of components from multiple vendors distributed across multiple physical platforms.The purpose of this Recommendation is to add capabilities currently defined for ITU-T H.323 systems and is intended to provide new ways of performing operations already supported in ITU-T H.323.

Gateway Control Protocol: Version 3 (Study Group 16)

ITU-T H.248.32-2013 网关控制协议:详细的拥塞报告包研究组16

This Recommendation defines a package that allows the media gateway (MG) to report the current state of its resource usage to the media gateway controller (MGC).The MGC can,according to its own capabilities,customize the set of resources reported as well as when the reports are provided.The resources that can be reported may be in the form of general resources and/or individual resources,and can represent either hardware or software resources.Based on the resource usage report received from the MG,the MGC may take corrective action to improve the efficiency of the whole system (e.g.,re-route calls,reduce possible message intensive audits, throttle calls,etc.).

ITU-T H.248.29-2013 国际计算机技术协会(CAS)强制登记信令包研究组16

The packages in Recommendation ITU-T H.248.29 provide ITU-T H.248 support for channel associated signalling (CAS) compelled register signalling.This can be used for R2, although the packages are generic so that they can also be used for other non-R2 compelled schemes.This Recommendation proposes methods to support:? standard en bloc compelling;? overlap compelling;? the ability to enable end-to-end compelled signalling.
