Packet domain; Mobile Station (MS) supporting Packet Switched services
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). The present document 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 3GPP TS 22.060 and 3GPP TS 23.060.
The present document 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.
