Most mobile operators around the world are already well on their way to all-IP networks. Their concern now is how to complete that transition and handle the substantial growth now being seen in mobile broadband services. They can address these concerns by choosing an end-to-end IP transport solution.
The benefits of an all-IP network are clear.
Ethernet-based IP transport, for example, reduces costs and enables service to all users, from low-revenue voice-plan-only users to intensive users of high-speed data services.
Security and QoS (quality of service) can be built in as part of the network design, providing resiliency and high availability on a par with traditional circuit-switched telephony networks.
An all-IP network meets future requirements, solving data and capacity bottlenecks and preparing the way for the Evolved Packet System (LTE and SAE).
The question many operators face - and subject of this Ericsson white paper - is how to make an efficient transition from their current voice-centric transport infrastructures to a fully packet-data-centric model.
- Mobile network overview
- Reason 1: reduced opex, capex and TCO
- Reason 2: shorter time to market and more efficient use of current infrastructure
- Reason 3: increase network security
- Reason 4: guaranteed quality of service (QoS)
- Reason 5: high availability
- Reason 6: assured migration path
- Reason 7: more powerful and efficient network management
