Core Network Standards
and Interfaces
(This section refers to
the Ericsson UMTS Core Model)
The Ericsson core network architecture fully aligns with the 3GPP
release 99 standards and complies with the interfaces worked out by the
3GPP. The separation of the control and user plane functions can be seen
as an enhancement to the release 99 reference model and aligns with a
number of important standardization initiatives in IETF, ETSI, IT-U and
other different industry forums.
As a result of the various control plane/user plane separation
initiatives in different standardization forums, a gateway control
protocol (H.248) has now been standardized by ITU-T.
