ITU-T H.248.66 PDF

This Recommendation provides guidance on mapping real time streaming protocol (RTSP) methods, error/status codes and header fields to ITU-T H.248 protocol information elements, packages and procedures. Several packages are defined to enhance interoperability between RTSP and ITU-T H.248, however the functionalities defined in these packages may be used for other applications/services.

RTSP operates between user equipment (UE) and a media server. This Recommendation assumes that the media server is functionally decomposed into a media control function (MCF) and a media delivery function (MDF). These functions can be realized in a media gateway controller (MGC) and a media gateway (MG). The Figure 1 illustrates the theoretical architecture in scope.

NOTE 1 – There may be other network entities between the UE and MGC (MCF), or the UE and the MG (MDF).

NOTE 2 – Alternative architectures are for further study.
