The (A/Gb and Iu mode) PLMN supports a wide range of voice and non-voice services in the same network. In order to
enable non-voice traffic in the PLMN there is a need to connect various kinds of terminal equipments to the Mobile
Station (MS). This TS defines the requirements for TE-MT interworking over the R-reference point for
the Packet Domain, including the protocols and signalling needed to support Packet Switched services, as defined in TS 22.060
and TS 22.060
This TS is valid for PLMN in A/Gb mode as well as for PLMN in Iu mode. If text applies only for one of these systems it is explicitly mentioned by using the terms "A/Gb mode" and "Iu mode". Please note, that the A
interface does not play any role in the scope of this document although the term "A/Gb mode" is used.
