Building an Integrated All-Service IP Bearer Network

Urgent Demands for All-Service IP Bearer Network

The service boom makes the development of mobile network technology focuses on changing voice service to data and mobile broadband service. And the traditional TDM/SDH-based network is too expensive and features low bandwidth availability as well as inadequate flexibility. As a result, carriers have to struggle in the conflicts between the data service which occupies much bandwidth but gives little back and the highly expensive costs in network operation and maintenance. So today carriers more and more focus on TCO of the network. 

Tracing back to the development of IP technology from generation to stacking technology at edge to the basic technology in core, it will finally realize that IP concept will be used all around, i.e. from network layer to service layer and from core layer to access layer. Here, the access layer over IP has become the most urgent problem nowadays. This all-IP revolution can reduces network layers, simplifies network processing, enhances network flexibility and makes network management easier; at the same time, all kinds of new services with both IP and mobile attributes can be implemented, which keeps the sustaining development of the network, reduces carrier’s TCO and gains profits.

The Key Features of Packet Transfer Backhaul Network  

As carrier-class IP RAN bearer network should consider the compatibility with the existing mobile network and the sustaining development of future network, it should has all sorts of interface such as TDM E1/IMA E1/STM-n/ML-PPP/FE/GE, besides it has to enable clock synchronization in mobile network, also provides end-to-end SLA, OAM and transmission technology to improve its operation management and users’ experience at the same time. With high reliability and service quality of SDH-like network, it makes full use of the statistical multiplexing and flexibility of the packet transfer together with the considerate awareness of the future network development, it is adaptive to the future development of integrated service, avoids the device replacement in the coming network revolution, and protects user’s investment. In a word, carrier IP RAN bearer network focusing on user’s demands and its TCO provides customers with the most complete solutions.

All-Service Packet Transfer Bearer Network Solution

ZTE iCAN all-service IP bearer network solution pays more attention to the key factors in all-service operation: more bandwidth, more service access, higher packet bearer efficiency, flexible service deployment, precise resource scheduling, differentiated SLA, lower TCO, unified multi-technology carrier-class software/hardware platform, solutions with IP/MPLS using packet as kernel providing multiple L2/L3 services and scenarios.

Integrated Multi-Technology Service Platform

The device based upon service integration providing flexible solutions can interconnect with the existing SDH/SONET network, so that, TDM can develop to IP packet transfer smoothly. The extensible Ethernet/MPLS kernel architecture realizes PWE3/VLAN/VPWS/H-VPLS/L3 VPN/MPLS-TP/PBT transmission platform, providing end-to-end OAM monitoring and fast failure location based upon service and network, and simple network management for user precise operation, which on one hand enhances the operation efficiency, on the other hand reduces OPEX at the same time.  The unified control platform for multiple services offers reliable protection and recovery, builds highly available basic network, provides clock synchronization solution and SSM, and supplies all sorts of cost-effective network solutions finally.

End-to-End Service and Management

PWE3 technology is used to realize tradition service implementation and set redundancy and protection to standard tunnel. Rich MPLS and Ethernet solutions provide end-to-end service implementation and delivery. Carrier-class end-to-end protection, recovery, service control, OAM performance monitoring and maintenance enhance the overall performance and service quality of mobile backhaul network. Together with simple management and operation, it reduces the TCO of mobile service.

Integrated Clock Solution

The clock synchronization solution provided by packet transfer realizes the service clock synchronization and protection, which matches the strict demands of the mobile access network for the clock, optimizes network deployment and saves the costs.

Future-Oriented Products and Services

After considering the compatibility with the traditional service, the future service development, and the development tendency of FMC, the service, basic network and product scalability should be guaranteed. Focusing on customer demands, standard service and flexible choice are provided, which further reduces the costs in user’s network construction and operation. It builds an advanced and operatable platform featuring sustaining development.
