China Unicom HSPA bearing mode will be final in the year

Author: The Guanglei May 17, China Unicom launched HSPA commercial in 56 cities nationwide, its network data transmission rate from 7.2mbit/s to 21.6MBIT/S, and launched the WO 3g 21m wireless internet card. In recent years, China Unicom fixed-line broadband and 3G business rapid development, the load-carrying capacity of the network requirements of the increasing.　　Especially in the HSPA network commercial, MSTP for mobile return load has been overloaded, the choice of new bearing mode is imminent. Early layout in the HSPA network before the opening, China Unicom has begun to the next stage of the load-carrying mode ahead of the layout. For China Unicom, the next generation of mobile transmission mode, it is also inclined to packet bearer technology.　　China Unicom has a long history of research on packet technology, when China Mobile has just deployed PTN technology, Chinese unicom experts have said that China Unicom has been in the laboratory research on packet transmission technology, based on its current network application to consider the choice of next-generation bearing technology. With the increasing traffic flow of wireless network, China Unicom began to layout the packet carrying experiment network at the end of last year to verify the feasibility of the technology in current network application. China Unicom Research Institute, a responsible testing experts, the construction of the experimental network involved in a total of 8 cities, 7 equipment manufacturers, 3 networking models, that is, full PTN model (End-to-end 2), full MPLS model (end-to-end three layer), layered networking model (core convergence Layer 3 layer + Edge Layer 2 layer),　　The test content includes 8 aspects: integrated service delivery, LTE phase Mobile return scheme, 3G Mobile return construction scheme, packet transmission network operation and maintenance, network performance under the Scale group network, interworking with MSTP network. While the experimental network test is still in progress, China Unicom will immediately pilot the relevant programs to complete the test ahead of time. According to the reporter understand, in the initial pilot of the 7 cities, have chosen to use packet transmission technology to carry out the independent HSPA business, according to China Unicom Group, before May 17, all realized the effective load on the HSPA business, and running in good condition, thus China Unicom basically finalized HSPA　　The business will use packet transfer technology to load. Select a dispute recently, for mobile back to the transmission of the way to choose which kind of hosting scheme is undoubtedly the focus of the industry, and for both options are related to China Unicom, facing a difficult choice.　　From the current load-carrying scheme, the PTN carrying scheme and the IP ran are the main way, however, the experimental test of the two schemes also have their own advantages and disadvantages. For the ptn carrying way, because China Mobile in the current network deployment earlier, its technical maturity, cost and other aspects occupy the advantage, and in China Unicom This test process, the PTN bearing program also took the lead to complete the test, into the pilot application phase. Because PTN technology is still based on the original transmission concept, its compatibility with the MSTP also has innateAdvantage of sex, at present, the main problem of PTN carrying scheme is the bearing aspect of LTE network, the function of PTN three-layer link is becoming necessary function in carrying LTE, however, it is not mature yet, it is more challenging for transmission operation and maintenance, on the other hand, its network management system has high complexity and still needs optimization. The hosting scheme of IP ran is based on the IP network, which accords with the development trend of the future network and has a strong advantage in the comprehensive bearing capacity. It is reported that Beijing Unicom adopted the IP ran comprehensive load network test has been completed, the results show that the IP ran bearer network indicators to achieve or better than the business network requirements, reached the target, it is worth mentioning that the IP ran program natural support for Internet services, IPTV, VoIP, Large customer dedicated line and other business integrated load. China Unicom National Engineering Laboratory Deputy Chief engineer Tang Xiongyan also said that IP ran in the future there is a broad space for development.　　However, the IP ran its own soft rib can not be ignored, it has not yet standardized, deployment costs are still high, and MSTP compatibility is still insufficient, the latter of the operation of the management of the major domestic operators is also a major challenge.　　China Unicom, a number of senior experts to reporters that there is still no clear use of which technology to carry, PTN short-term deployment has a greater advantage, and IP ran comprehensive capacity in the future also has greater potential.　　Two-way introduction of a manufacturer expert to the reporter, China Unicom for the choice of new packet bearing technology is still in the testing phase, the second half of this year may have small-scale collection, for the selection of two kinds of bearing options will be based on the test results of the experimental network to make weights. From the perspective of China Unicom's top executives, the two technologies are not inclined to abandon one and show signs of two-way introduction.　　As Tang Xiongyan said, China Unicom's current demand for new types of load-carrying mode is mainly concentrated in the HSPA Network load, MSTP network overload situation, will consider to PTN evolution, and if the need for new Metropolitan Ethernet system, prefer to adopt IP ran scheme. The entanglement between PTN and IP ran has intensified, some experts say PTN is a transition program, and IP ran is the final direction, and the current network deployment, PTN performance and the current network of good compatibility, IP ran scheme is not revealed, and from both sides of the industrial camp, have a strong momentum of development, And eventually all will move towards integrated IP bearer.
