Introduction
This standard specifies the necessary interfaces to support the
bearer traffic between Media Gateways in the initial step of the
Legacy Mobile Station Domain (LMSD). The requirements for this work
are defined in [6], and the overall architecture model is defined
in [5].
This standard defines bearer support of G.711 PCM encoded voice
over IP as defined in RFC 1890 at a minimum, for use between media
gateways in a cdma2000 Legacy Mobile Station Domain. This standard
utilizes existing IETF and 3GPP2 protocols when applicable to
minimize the new work needed. The necessary signaling needed to
setup the bearer paths is defined in [3].
For the initial release of this standard, the following basic
capabilities defined in [6] are supported. Enhanced capabilities
may be defined in future versions of this standard:
- The yy interface spans across a managed IP network.
- The QoS mechanism for the yy interface is not defined in this
version of the standard. - All Security issues between Media Gateways are not defined in
this version of the standard. - TrFO support over the yy interface is not defined in this
version of the standard. Handoffs between LMSD networks are not
supported over the yy interface. - Handoffs must be supported using existing TIA/EIA-41 signaling
and Inter MSC Trunks.
