All-IP and network convergence is the future direction of the inevitable evolution of mobile networks, whether the business itself, or the voice, data and multimedia bearer will achieve full IP. With IP technology, Communicate Network-wide IP network for progressive development will interoperability, integration of the network structure, which will not only help operators realize a smooth evolution and efficient network deployment, but also reduce CAPEX and OPEX operators, while operators investment protection to achieve rapid return on investment, and ultimately a variety of network roaming and service access. The same time, we must also see that the current global telecom revenues are still dominated by basic voice service, particularly in emerging market operators, voice service revenue ratio of 80% or more, regardless of how networks evolve, this part of the users and their revenue is the primary consideration carriers. IMS-based voice services, but now can not provide quality of service commitments (QoS) guarantee, on the other similar services providing real-time remains to be demonstrated. Therefore, the wireless access network and core network-wide IP-based premise, will appear in future network-based voice services to 3G CS domain and IMS-based multimedia services to long-term coexistence. In addition, the ability to guarantee carrier-grade network, network reliability, network flexibility and network quality of service will be the main problem facing operators. | 1, All-IP carrier-grade common platform for laying a solid foundation for the network IP network with all the development, especially on IP protocol-based exchange business in different networks, the integration of the network has laid a good foundation. The next-generation network bearer and control separation, control and operational separation of thought and to IMS softswitch-based mobile network coincides with the evolution of ideas. All-IP architecture as an active initiator and leader, in 2004, ZTE Communications launched the first in the industry All-IP carrier-grade common platform for development consistent with full IP control plane and media plane separation of the system architecture to ensure system reliability and stability. Within the system design of two sets of Ethernet, a set of interconnected streams, one for internal control, signaling flow of Internet, this innovative design to ensure system reliability, will the media from the physical plane and control plane traffic isolation, to avoid unexpected system media flow on the control surface impact. | Another idea is to design a common platform in the IP control plane with the media surface and the design of non-separation mode, the media flow and control flow in a plane Ethernet switching exchange.
As telecommunications increasingly fierce competitive environment, the requirements on system capacity increasing, the system in some special period of time such as during the holiday season will face a large unexpected traffic impact. Devices using this system architecture and control flow because the media stream will influence each other, will face down the quality of service, or even the systematic risk of paralysis. Communications system in 2008, then New Year service peak, Hyderabad, India, ZTE All-IPBSC withstand the impact and a large amount of test users, two of BSC's voice traffic during peak were normal Call amount of 8.8 times and 6.8 times. Hyderabad in the period all of the other operator's network paralysis, only ZTE's equipment survive. ZTE's All-IP solutions, industry-leading three years for full-scale commercial IP, as of March 2008, ZTE CDMA products have successfully entered more than 70 countries, more than 120 operators in more than 135 million lines worldwide . As in CDMA2000All-IP ZTE's leading position on the further consolidation, ZTE has become a global leader in CDMA, Yankee group2008 years of a consultation report shows that ZTE CDMA integrated the ranks of top retaining its position as the world's first group (see Figure 1). Second, comprehensive disaster recovery programs on the networks they have always done Single system capacity as a huge, full IP communications equipment on the stability and reliability requirements are higher, at all levels need to do full backups. Order to maximize the protection of sustained and stable network operation, ZTE CDMA2000All-IP solutions designed to fully take into account the structure of system redundancy backup mechanism, the core parts and equipment with 1 +1, N +1, M + N and so the backup way, the core database 1 +1 standby, dual-network dual-plane network architecture to ensure that the network plane without a single point of failure. Disaster areas in the network elements, ZTE CDMA2000All-IP solution supports Ap-Flex, MGW load sharing, MSCe disaster recovery, HLRe disaster recovery, backup and other network elements. The All-IP-based disaster recovery solutions that take full advantage of the flat IP network, the characteristics of a TDM mode to avoid a similar program in a huge waste of transmission resources. 3, the industry's most efficient transmission scheme of operational savings For those who carry only the traditional TDM network, no existing IP backbone bearer network operators, ZTE to provide IPoverE1 ensure the full enjoyment of operators to bring the advantages of All-IP: E1 bearer network in support of TrFO, RTO, save sound codec resources 30% to 40% or more; and TDM compared, IPover E1 E1 transmission efficiency program but will increase to an incredible 11 times, saving E1 Lease Cost. For those with existing IP backbone bearer network operators, ZTE to provide IP overFE / GE allows operators to experience the All-IP technology has brought changes: Support TrFO and RTO, the vocoder resources to save 30% 40% or even higher; network flat, increase network scalability and flexibility; and TDM compared to the bandwidth savings of up to 80% of voice transmission, saving the cost of network construction and rental costs, will lower TCO; For remote areas, islands of coverage, and transmission operators with limited resources, ZTE to provide satellite links and microwave networking solutions composed of a large local network of programs to address the wide coverage and routing roundabout, to help operators limited access to satellite links to more users, improve network profitability. 4, perfect QoS mechanism to ensure excellent network IMS is an end-all IP architecture to provide end to end VoIP Business to replace the traditional mobile phone business. For VoIP calls, the primary factors affecting its development is the need to provide better QoS mechanisms to ensure its voice quality is not worse than traditional mobile phone voice quality. Figure 2 shows CDMA2000MMD network to meet end to end QoS requirements, and set up multi-layer loaded with different service levels, network element between the end QoS assurance mechanism. open_hack.new_open=function(url){
