From Network-Centric to Service-Centric

Network-Centric Service-Centric Impact

RAN RAN is of primary importance RAN is a means of attaching a subscriber to the network, in much the same way that an Ethernet port connects a device to a fixed network, albeit significantly more complex.

• Shift away from highly-integrated access and services• Decouple radio from end-to-end service delivery

RANDeployment Model

Macro base stations are the predominant deployment model.

Macro-, pico-, and femto- base stations, and also unlicensed wireless technologies (such as Wi- Fi) and fixed technologies (such as 802.3 Ethernet), all play a vital role in delivering content to a subscriber.

• Requirement for session persistence and identity management across access technologies• Access technology transitions must be transparent to the subscriber

IP Services Network The IP network is seen as a necessity to facilitate the transport of subscriber data.

The IP network is considerably more important - helping with optimal service delivery, session continuity across access technologies, and technology convergence.

• Creation of a convergent IP services delivery network• Deliver the same subscriber experience across all access technologies

IP ServicesDeployment Model

The mobile gateway is responsible for all mobility functions, such as session persistence.

Many different elements― from the client, to the network, to the application and content―are responsible for mobility functions.

• End-to-end deployment for mobility• Clients, network elements, and applications all play a vital role in the subscriber experience
