Until today in development of mobile network, has been deeply integrated into the "Internet" elements, all kinds of mobile Internet business applications as well as significantly improving the end user experience is also a strong challenge, including GSM, td-scdma and WLAN network infrastructure.The future how to realize the coordinated development of a variety of heterogeneous network equilibrium, how to realize the intelligent traffic management, is represented by China mobile in front of the global mobile operators focus problem.

 

 

The main problem facing China mobile mobile broadband era

 

The challenge of data services

 

 

China mobile is currently data network business flow is quickly beyond voice business, keep the annual compound growth rate of nearly 150%.Is expected in the next few years, such as smartphones, tablets, the rapid popularization of the intelligent terminal and mobile Internet business applications, with the rapid development of data services will continue to present exponential growth, the consumption of data flow of network resources will be the voice of dozens of times on even one hundred times.Face the huge impact of digital flood brings to the wireless network, the construction of high bandwidth, high efficiency, low cost wireless network become the urgent demands of China mobile.

 

 

Four net operating situation of the long-term coexistence

 

 

In the future, China mobile will also operate GSM/td-scdma/WLAN/TD - 4 pieces of LTE networks.On the one hand, considering the difference of the domestic economy lead to the diversity of customer needs The factors;Four network system, on the other hand, the differences of obvious, and the traditional network change regularity between the network life cycle is different, how to develop the network long-term coexistence, coordinate the balanced development strategy, is at present the main problem facing China mobile.

 

 

Unbalanced development of four net and long-term coexistence, inevitable requirement of four network synergies, complementary advantages, to realize the coordination equilibrium development of low cost, high efficiency.Of course, the four network imbalance under long-term coexistence is a dynamic situation, no one could predict the unbalanced now what will happen in the future.So, we put forward "coordination network construction, intelligent traffic management" strategy, around the center thought, seek a long-term mechanism, realize four network development at different stages to meet customer business experience "a net".

 

 

Four cta with analysis of the connotation

As mentioned above, the four core of cta with is on the premise of four network coexistence, through collaborative operation to provide a good business carrying network, so as to ensure the requirements of its low cost, high efficiency., in its network construction should be based on "coordination network development" strategy;And in order to realize the experience of a net, the network management is the need for "intelligent traffic management.Specifically, this strategy can be summarized as: mobile business, the customer to choose business, business network, the network management traffic.

 

 

Mobile provides business: China mobile service provider, through high quality to satisfy customers everywhere of interconnection and communication needs, this is the basis of four with cta.Service into customer satisfaction, trust, depend on the three stages, including the third stage is the highest state of the service, China mobile, of course, also should be to provide worthy customers rely on services as the goal.We need to clear, I have to provide the customer as the center of the business of business, customer value and demand satisfaction is the only standard to judge the quality of the business.

 

 

And customer demand is the comprehensive variety at present, China mobile will need to provide rich business to meet customer demand, reasonable make China mobile's high quality service brand, laying solid foundation customers rely on services.Particularly in the era of mobile Internet, customer needs emerge in endlessly, timely according to customer requirements to launch targeted business, become China mobile's focus, and this would require a elastic flexible to adapt to the different business environment optimum bearing the basis of the network.

 

 

Customer choice of business: customer demand is differentiated and diversified, each customer can't use all the business.Customers according to their own needs to choose, that is, the customer to choose business.Customers choose final performance of the business, is a key you need access to the business, rather than because of the difference of network system for complex operation.

 

 

So, under the four cta with the customer to choose business should not cover technology, which don't need to tell the customer manually choose to use net, this requires operators to the most common Volkswagen group as the object, to stand in the perspective of the customer and the value direction, realize customer is concise and easily select the business.If the business use way too specialized, without realizing customer value view, can cause at a very small.So, on the basis of China mobile in provide a rich business, make the customers need, simple and convenient to choose business, achieve a net experience, guarantee the high quality service, is that the four cta with second intension.

 

 

Select network of business: the customer to choose, how the web support business is four cta with third connotation, namely business network.China mobile, the rich variety of business and four network to form a many-to-many relationship with high dimension matrix, the key is how the web initiative to align business.

 

 

In the concrete plan implementation, the network is not isolated unidirectional business selection.On the one hand, the technical characteristics and development of the four network level differences, business choice need to consider network status quo and evolution ability;Business, customers, the development of the terminal, on the other hand, is a progressive process, need to consider the business development and evolution of the network node matches.In addition, the network is not passively bearing to match business, network construction and development needs to take the initiative to adjust and align business, to the organic combination of business and network, promote each other, matching development.So, choose the network business, network business is that we must follow the principle of active adaptation, or through the appropriate network to support the corresponding business, to meet the requirements of the business choice network and connotation.

 

 

Management of network traffic: cta with the fourth connotation is network management flow, namely, low cost, high efficiency support high quality customer experience, need to integration, intelligent traffic control mechanism.If still the continuation of the present stage the network independent pipeline system, in the case of GSM network overload, to pull the data to the td-scdma, the future is likely to be td-scdma network overload, and to pull the voice business to the GSM network, China mobile will continue to struggle with business network change back and forth non-virtuous circle again and again.

 

 

Traffic management, therefore, must be on the basis of the four network platform and integration, realize the visual, controllable, integration, intelligent traffic management, the purpose is to ensure fair and reasonable use of network resources, guarantee the customer business experience, guarantee the maximum benefits of the network, finally realizes the low cost high efficiency support customer high quality experience., of course, the realization of the flow control is a long-term and phases, the terminal has realized all the multimode and network side based on four load condition through the network management function and the capacity of configuration, implementation flow and the four adaptive network resources.In short, is to ensure that customers in the use of business, enjoy the best of the best business experience provided by the network resource allocation, which is the core of network intelligent management flow.

 

 

Four cta with the development of the target network architecture

In order to meet the customer experience of a net, realizing the unity of four net best efficiency, cost, the optimal network, four cta with the goal of developing network architecture by the wireless controller, four network integration linkage analysis support system, layered three-dimensional cellular network, connecting the multimode intelligent terminal of four parts, as shown in figure 1.

 

 

Super wireless strategy controller: four cta with most emphasis is take the initiative to realize the resources and the optimal matching of the business, in RAN four network cluster fusion point to a section, fully coordinated wireless resources, realize the unified control.The key nodes is super strategy wireless controller, it can be a logical node, also can be a physical entity, support network synergy also compatible with the conventional four network independent work mode, is located in the core network and RAN.GBSC/RNC/eNodeB node in a wireless resource management (RRM) function gradually converge to a wireless controller, realize RRM function, can choose based on terminal position and the types of business applications hosted network, wireless resources and business of optimal matching.

 

 

Four network integration linkage analysis support system: despite the super wireless strategy controller to realize the wireless resource of centralized and unified control, and resource scheduling still needs a "staff" for intelligent coordination, so you need to set up four web linkage analysis support system, to realize comprehensive perception of network quality evaluation of four network, support migration based on the customer perception of business optimization, so as to meet the demand of network traffic management.

 

 

Layered stereoisomerism honeycomb group network: down from super strategy wireless controller, four network needs to provide enough wireless capacity and coverage, more standard stereo heterogeneous network is the development direction.At the same time, to meet the multimode terminal realize a net experience between different networks, the initial need in GBSC/RNC/eNodeB/signaling connections between AC, optimize network interoperability between the experience.

 

 

Connection multi-mode intelligent terminal, with the popularity of the future smart phones, through increased control software on intelligent terminal, also can implement strategy adjustment and automatic update, implement four network coordination mechanism of China mobile terminal level of compatibility.The current industry one of the few major chip manufacturers have introduced a preliminary meet the demand of China mobile's four cta with development of multimode terminal chip, support GSM/td-scdma/TD - LTE/WLAN, but in terms of specific support four network seamless integration synergy, still need for standardization and industrialization promote as early as possible.

 

 

Super wireless phased evolution strategy controller and implementation path

Super wireless strategy controller is the core of the four cta with development goal of network architecture, but according to the development of technology, the wireless strategy controller will gradually from "logic protocol communication, scheduling, equipment entity to fusion" four phases, as shown in figure 2.

 

 

The first stage in WLAN and GSM/td-scdma/TD - LTE, on the basis of traditional mobile cellular networks such as integration, mainly
