The 3rd Generation Partnership Project (3GPP) is the primary body for developing technology specifications for cellular networks. It self-organises through its Working Groups coordinated by the Chairs of the Technical Specifications Groups (TSGs). RAN WG3 (Iu, Iub, Iur, S1, X2 and UTRAN/E-UTRAN) is responsible for the development of specifications dealing with UTRA, Evolved UTRA, and beyond, and in particular for: – Overall UTRAN and E-UTRAN architecture. – Synchronisation in UTRAN and E-UTRAN. – Stage 2 work of Work Items allocated by TSG RAN to RAN WG3. – UTRAN and E-UTRAN O&M requirements. – Iu interface protocol specifications, i.e. access stratum protocols over the Iu reference point. – Iur and Iub interface protocol specifications. – Iupc interface protocol specifications. – Iubc interface protocol specifications. – Transport of implementation specific O&M between the Management System and Node B. – Application of the RANAP on the E-interface. – Iu-ant interface protocol specifications (RF-parts of the layer 1 specification are under the responsibility of RAN4). – Parts of Iu and Iur protocols common to GERAN and UTRAN (Iu-g and Iur-g). – S1 and X2 interface protocol specifications. – M1, M2 and M3 interface protocol specifications. – Iuh, and Iurh interface protocols specification. – LTE Positioning Protocol A (LPPa). – Xw interface protocol specifications.
