13 Media Gateway 12 Mika Ahola Features of New Architecture: Separation of call control and connectivity/bearer control Flexible architecture that is possible to use for any connectivity (ATM, IP, STM) Keep the N-ISDN/GSM service paradigm. Use MAP, ISUP, etc. All devices needed for user plane manipulation are moved to the Media Gateway (echo cancellers, codecs, etc.) Possible to place infrequently used equipment in centralized resource nodes Transmission efficient to have coded speech all the way to the rim of the PLMN UTRAN and the Iu interface is ATM based. A good way to bring in ATM in the core network is needed Allows stable and mature introduction of UMTS networks since building on GSM products New protocol to control media gateway remotely Services/applications outside core network enables service convergence In line with standardization trends

17 Media Gateway 16 Mika Ahola Reference Architecture for an All IP Network Source: 3GPP TR V1.0.0 ( )

18 Media Gateway 17 Mika Ahola Summary Ericsson offers via the layered architecture an evolutionary approach to the multi-service network Ericsson offers deployment of ATM & IP-based transport technologies for both UMTS and GSM/GPRS based on open standards. A Media Gateway product is introduced handling all user plane data in an integrated way and that connects to ATM & IP backbones New network architecture will be included in release 00 of 3GPP
