Liu Yunjie Chinese Academy of Engineering: "Soft exchange untimely"

As the IMS and HSDPA, HSUPA rapid development, makes the soft exchange value and life cycle greatly reduced. Softswitch untimely, to this point, operators should be fully estimated.

We are talking about NGN, NGN we have defined four areas: the first is based on packet switching technology, most of IP technology; the second is to provide telecommunications services, including all business, including, for example video services; The third is to separate hosts and operational control, and bearing all the bandwidth to provide a QoS guarantee requirements; the fourth is to ask the user can select any operator, not the subject of a certain operator. Should be based on the definition of these four aspects, in accordance with the objectives of such direction to the NGN.

NGN concept is the development of the telecommunications industry for many years the concept of accumulation is the goal for many years. Background is a long time, the network is the traditional telecom industry, one a business network is separate, but the industry has been pursuing a goal, can you separate the network into a comprehensive unified network platform to evolve. 70 years from the last century the pursuit of ISDN, to the 80's B-ISDN, then 90 years of the Internet, do not achieve the intended purpose. Now we talk about the NGN, the ultimate goal is to achieve multi-service, to achieve network convergence.

To achieve this goal, from the perspective of the telecommunications sector has to face and solve four problems: the first is the load problems; second is how to achieve network bearer network integration; third, MAN and How to access the network in accordance with the concept of NGN deployment; the fourth is how realization of NGN network architecture business goals.

What to do with technology bearer network, which is plagued us for years, because it can provide routers and ATM bearer network is the two technologies, but the two technologies do not adapt. In addition to the other two technologies, there is no third technology? Router technology why not? In short, the time when the network failure, network routers and other nodes in the network took place less than perceived status, this is because the router does not test, no interaction network information function. ATM's problem is not the ability to handle IP, and now more than 90% of applications are all IP applications, so we come to a dead end that the ATM is gone, in fact, if coupled with IP-ATM processing capacity, or have applied prospects.

The second challenge, how in a variety of online business hosting? Solutions proposed by the industry through the design of the logic of virtual private network over the region, each private network has a business, every business has its own routing table, have their own QoS level, and between these logical networks mutual isolation, which would address reliability issues. This program provides a way to integrate the three networks, it is all in the pursuit of goals.

The third issue is to realize NGN, how to achieve integration in the MAN architecture? MAN to make some new architecture and standards, no new structure and standards, MAN will not meet the requirements of the next generation.

Now in the access network side, we note that the problem is UMA, is license-free mobile access. The question now is, cable network bandwidth is unlimited, bandwidth capacity increases, but the wireless network bandwidth is always limited, because by the frequency limitations. But the wireless applications from the current view of almost unlimited, and now wireless applications varied, scenic side is fine, we all moving in mobile aspects of development, this is a reality. This is a great contradiction between the two: one is the limited resources, the application of infinite; one is unlimited resources, applications, has many constraints. How these two technologies together like this is always the issues of foreign and domestic should follow up studies in this area.

Fourth, on operational integration issues. IMS and softswitch is now in the country yet there is no unified understanding and views, of course, very difficult. My view is that IMS softswitch with the biggest difference is that, IMS can provide more services for the application. Softswitch every business should have its own set of design, IMS is not only in the planning can be unified, in fact, can be done in the QoS context unification is not only a bearer and control separated, you can separate the user interface, all access into the way, whether mobile or fixed way means can be achieved. IMS data can also be centralized. From the business point of convergence, IMS has great appeal and advantages. In addition to providing voice softswitch outside the big problem is in the application have great limitations.

Softswitch and IMS architecture choice between, is the troubled telecommunications company, in doubt, look unclear. However, IMS will replace the soft switch, which has a global consensus.

As the IMS and HSDPA, HSUPA rapid development, makes the soft exchange value and life cycle greatly reduced. For this, operators should be fully estimated. My personal view is that the soft switching untimely.

Softswitch is five or six years ago, emerging technologies, just five or six years ago, the telecommunications, IT industry downturn, continue to go trough the process, which makes the soft switch has yet to push the use of, or application is not universal. When the IT industry began to rise from the bottom, when, IMS rapid development, makes the soft-switching will be relatively short life cycle.

Operating companies in the choice of soft-switching and IMS, if you consider the deployment of IMS architectures, requires network support HSDPA and HSUPA, and the related QoS mechanisms. Because IMS is not on, is not the standard into a mature, standards will change the future. Not on HSDPA, HSUPA, the IMS may, however, can only provide part of the business, can not provide all of the business.

In addition, IMS support for VoIP and multimedia services, the IMS is certainly risky, but the risks and benefits is the co-existence. Assess the risk, if the IMS can be successful, avoid the soft switch investment. Because these investments can not be completely smooth transition to IMS, there is always some equipment can also play a role though, but do not throw no good, do not throw good. If you do not have the above conditions, soft switching, then we must take into account the smooth transition to the IMS feasibility and long-term coexistence of the problem.

Fixed network operators to replace the current soft-switching PSTN is so urgent? I personally doubt. PSTN is now applied very well, did not say growth may be very large, there is no need to use new technology to replace. Now the problem is that PSTN can not provide more new business, I think that the provision of new services with IMS softswitch more than the advantages. With the maturity of IMS, network and application will do more.

So I think that telecom operators and equipment manufacturers should spend more energy on research and development of the use of IMS.

"Aion," summed up their experience with the bow trap star

1, glue traps

The most primitive traps, strange choice for control, absolute good skills, both single-P, copy, control strange kites emergency is a good thing

2, toxic trap

Early I used more rarely now I basically use the CD and glue it overlapping, single Shaguai and PK still used, very good, usually have arrows instead of using highly toxic

3, Explosive Trap

Poor lost the skills I have friends, do not feel much harm beating 鎵撴? ... ...

4, bound trap

Discarded, and the glue of CD's it, not to open the game, forgotten, discarded anyway, because after the attack with the click will automatically unlock the shackles, when I really want to use glue or replaced with a group tied the

5, dust trap

I feel better with the particular and the sword cut the time of the

We went to Magic hole killing, using the dust, the soldiers asked not to have feelings, the soldiers did not feel that high dodge, ah, oh silent

But Star team and kill, kill anti-strange star when the treatment increases the blood, if you have a strange not to give him up a dust he Naozhuo to good effect, he said ... well ... very well

Dust Summary: This slows down the other side singing justifiable; especially the BOSS to send large skills, they can give you the opportunity to walk around thinking; to evade the high point of the people will feel easy to use, cut each other than Kazakhstan, under the books, brush JY, particularly in group attack, put a good, good things

6, groups of binding (forget his name, the range of 10 meters is bound trap)

I occasionally use the following, in particular a collective sprint, it was strange group received chase, I put one, then ran to see the back of the green as they grow barley grass, haha

This trap defects can not attack the strange, the attack about, breaking the trap on

7, rope trap

Branding skills, how do you say, people love so full of hurt, ah, secretly put a skill, quietly pull the enemy to step on, silent prayer Do not resist the occasional non-resistance, joyful hearts, straining under fire fire, fire end, hundreds of blood found on it ... ... as a small nail hair demonic skills it

Throw a well-deserved

8, dashed trap

DP consumed large strokes, and LP to kill crows have been three personal attacks, which the other party has cured, sword star, died after being cured by my mill, sword star finally catch up with me and I LP to kill him, I suddenly see cure climb from the ground up ... ... a strong Xisha him, the thought of his own on the first resurrection, suddenly saw him up ... ... Ghosts, and then I estimated that he used the self-resurrection Stone (until the resurrection with their own skills)

And this time, my wife and I are very dangerous, and blood are less than half, and pulled up on the ground if another cure, together with blood, as we have set, and I so he ordered a DP medicine, put a burst ( not used this stuff before it), because everyone in the pile of cut, and on the sword and I just put a anti-dust + crimson before to now, I see the cure not care for her blood increases, transient I put a burst on the stoop, "H", healing and blood is running all get on the ground of the Sword Star

I have stunned for a while, my wife asked me how they had ... ... a ghost that shattered so fierce that oh

On the other after

Casual chat, please bear with suggestions Oh!
