Digital cellular telecommunications system (Phase 2+); Universal Mobile Telecommunications System (UMTS); LTE; Packet domain; Mobile Station (MS) supporting Packet Switched services (V11.0.0; 3GPP TS 27.060 version 11.0.0 Release 11)
"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."
