There are many access networks in China, and wireless access networks are also widely used in people's daily lives. So I studied the problems in the development of access networks. I would like to share with you here, hoping to help you. First, the current user experience before the integration of fixed and mobile services and networks, whether it is mobile or fixed services, their businesses require multiple contracts, multiple numbers, multiple user data files, and multiple bills. At the same time, carriers also have multiple customer channels. In addition, the business environment that users can enjoy depends on different terminals and access networks. All this makes it inconvenient for users to use their services.
User expectations. All users have the following expectations: No matter what business they use, whether it is mobile or fixed business, they want a single contract, a single user data file, a single bill, and a single customer channel. However, no matter what terminals they use, they can use the same business environment. In addition, it can achieve seamless, secure, and convenient business access networks. It can use broadband fast access networks and a wide range of content services, as well as enjoy optimal charges regardless of the services they use. To meet these expectations, only the integration of fixed and mobile businesses and networks can meet these expectations. This is the market-driven aspect. It is an important driving force for user needs.
Carrier Requirements. From this figure, we can see whether it is a fixed operator, a mobile operator, or a full-service operator. Because there are also a part of all-Business operators abroad, there are the following five requirements. First, all carriers hope to increase business flexibility and improve user experience. This is the goal of all carriers. Second, all operators hope to increase their attractiveness to users and reduce their off-network rate. In addition, this reduces the off-network rate. Third, we hope to further increase revenue and increase the ARPU value. Fourth, all operators hope to reduce investment and operation costs. In terms of network architecture, all operators also want to simplify the network structure.
In order to meet the needs of operators in several aspects, and only the integration of fixed and mobile can meet the needs of operators, this is another aspect of the market driving force of fixed and mobile convergence. Analyze the driving force of fixed and mobile integration technologies. First, the standard progress. At present, international standardization organizations are developing standards based on fixed and mobile convergence. For example, this figure uses IMS as an example. Currently, 3GPP, PP2, ETSI, ITU, OMA, and IETF are supported, they set standards for fixed and mobile convergence based on business, network, and various protocols, respectively, the Standardization progress also laid a solid foundation for the integration of fixed and mobile businesses and networks.
The maturity of technology. For now, for example, dual-mode terminals, mobile devices, Bluetooth devices, or WLAN terminals, as well as mobile and PHS dual-mode terminals, the maturity of dual-mode terminals also lays a foundation for the integration of fixed and mobile services. At the same time, the experimental scheme based on the current network, such as the fixed and mobile convergence network solution of British Telecom Based on the OMA structure, has also been mature. The above introduces the market demand which provides the demand for fixed and mobile businesses and network convergence, while technology lays a solid foundation for the integration of fixed and mobile businesses. Let's talk about fixed and mobile convergence.
First, it is fixed and integrated, that is, the concept of FMC, which is currently popular. FMC is the integration of wired and wireless technologies and services. It is embodied in the ability of users to obtain any services at any time and anywhere through any terminal and suitable access network devices. Business order and use are independent of the access network method, and FMC provides users with simple and convenient business use.
The vision brought by FMC. No matter what type of access network is used, because only the access network is different, because only a unified terminal can enjoy the same service. Therefore, fixed network and mobile convergence are designed on this figure, in terms of business and network architecture, it involves all aspects except the access network mode. End-to-end is the first terminal device. Some dual-mode and multimode terminal devices are required.
Secondly, a transmission platform, such as a network, needs a unified core function network, such as a core network based on the softswitch architecture. A unified business platform is required for a fixed and mobile business platform. Next, the business content also involves mobile and fixed integration. A support system must also support this integration.
In an intuitive sense, fixed and mobile integration is mainly reflected in three aspects: first, business integration. Second, terminal integration. Third, network convergence. We propose to use one or more devices for business integration, and provide users with the same and integrated services through one or more connection mechanisms, for example, a number, a bill, a unified message, cross-mobile phone and conference, integrated billing, and integrated VPN. Here I think the bundling and content sharing of fixed network and mobile services are also a manifestation of business integration. In terms of terminal integration, you need to use a single terminal device to access multiple network services, such as multimode terminals, mobile and Wi-Fi dual-mode terminals, and Bluetooth dual-mode terminals. Network convergence requires unified core network and service control. IMS should be a long-term goal of network convergence.
Focuses on business integration and network convergence from the embodiment of fixed and mobile convergence. First, the integration of services should be reflected in the integration of business platforms. For example, the integration of intelligent networks may require an integrated intelligent business platform in the future. Whether it is a fixed network, including PHS or mobile networks, it provides some integrated intelligent network services by implementing integrated intelligent networks, such as integrated VPN and No. 1 communication. Second, the shared data value-added business platform. Fixed and mobile shared data value-added business platforms can flexibly combine some businesses and provide some integrated business content. Another embodiment of business integration is the integration of the Operation Support System, which can provide users with one-stop services, unified bills, and unified recharge cards for their businesses.
Another manifestation of business integration is business intercommunication and combined marketing. In terms of business intercommunication, such as SMS intercommunication and multimedia intercommunication. In addition, business bundling is also a manifestation of business fixation and business integration. For example, the points of the fixed and mobile services for all business calls, the combined discounts and time-period promotions of the fixed and mobile network fees. This is because business bundling is only possible for fixed and mobile integrations. Business integration-Business resource sharing. For example, for business content sharing, mobile and PHS can share some data value-added business content. Share content resources. For example, mobile can share SP and CP resources with the Internet and PHS.
First, the relationship between FMC and IMS. IMS should be a long-term FMC architecture, fixed and mobile convergence, its development will inevitably go through several stages: first, we are currently in a stage, called the pre-IMS-FMC stage. Next we will develop to domain-level IMS and end-to-end IMS. Pre-IMS-FMC has appeared before IMS could run, such as UMA, IMA solutions, such as UK telecommunications and Vodafone cooperation has provided Bluetooth mobile phone solutions. The following figure introduces the FMC Implementation Scheme Based on the UMA structure, which is also the BT implementation method. From this figure, we can see that there are two key devices to achieve the integration of fixed and mobile networks. One is a dual-mode terminal, and the other is a new UMA controller. Dual-mode terminals enjoy mobile services outside the room. Because of the BT structure, they enjoy fixed network services through Bluetooth in the room. Users can achieve seamless switching between the mobile network and the fixed network.
The process of integrating networks into a converged network. Currently, we are in the pre-IMS stage. We can initially achieve the integration of fixed and mobile services and networks based on the UMA and IMA solutions. The next step may be to the IMS core network. Network-based convergence has a smooth evolution process, which brings benefits to end users and operators at various stages. In the current phase, the FMC solution of pre-IMS can bring the benefits of the operator to some new businesses with profitability and help increase user loyalty. The benefit to end users is that users can enjoy low rates and enjoy convenient use. For example, when an end user uses a mobile business outside the room, some low-rate fixed services may be used indoors, which minimizes the user's fees. At the same time, he uses the same terminal and does not need to run from the outside to the room to change the terminal, which makes the user's business more convenient.
With the evolution, it will also bring some benefits to operators, reduce investment and operation costs, and build an efficient network. The benefit to end users is to provide end users with new services. The long-term goal of FMC is to integrate some features into IMS. First, IMS provides a unified and powerful service engine for various access methods. The IMS core network provides an open business environment, and it completes the service routing engine between various business application platforms and IMS clients. The IMS core network integrates networks at the business level and provides a unified service support platform for different networks, such as mobile networks, WLAN and ADSL, in addition, in different network environments, the same services of terminals can be crossed and seamlessly roaming.
The IMS service has nothing to do with the access network, and the access network has nothing to do with it. The IMS terminal and mobile phone can access the IMS network through an IP address, the access network can be a different fixed network or a mobile network. The implementation of IMS services is a multimedia service that provides IMS users with real-time cross-platform and QoS Assurance. In addition, the IMS service provides services to users in the region where users access the network.
The above analyzes the recognition of fixed and mobile services and network convergence. The following is a summary. This is because the first section describes the market drivers and technology driving forces of fixed and mobile convergence. What are the benefits of fixed and mobile products to end users? This is what Fixed Carriers and mobile carriers need together. The integration of fixed and mobile services can bring users a variety of services anytime, anywhere, and freely choose, the best rate, the best service bandwidth, unified bills and numbers can be achieved. business integration makes full business operation inevitable.
First, analyze some cases that have achieved the integration of fixed network and mobile core systems. At present, a number of carriers outside China have begun to implement the convergence of fixed network and mobile networks, and many carriers in China have started research in this area. For example, I introduced BT and Vodafone just now. They developed Bluetooth terminals. NTT DoCoMO has released a WLAN/3G converged service. users in the 3G network are the same as ordinary users and can achieve seamless switching within the enterprise, WLAN provides users with a wide range of data and voice services. Integration is an inevitable choice for market development. Why?
First, the user needs. This is what all carriers require. Users must provide integrated solutions. I saw a consulting report some time ago. A large foreign consulting company conducted a survey to investigate users' demands for fixed and mobile integrated services in the next few years. This survey report concluded that more than 60% of users, nearly 70% of whom hoped to enjoy fixed and mobile integrated services as soon as possible in the next few years. Therefore, the integration of fixed and mobile services is primarily about users' needs, which are irreversible.
Second, the development of technology and business also provides the possibility of integration. In the domestic telecom market, to provide fixed and integrated services, operators must build on full-service operations. Therefore, business integration makes full-service operation a choice for operators. Moreover, both fixed operators and mobile operators require full-service operation to meet customers' needs for telecom services. In addition, from the perspective of the world, full-service operation is also a general trend in the development of the telecom industry. Therefore, China's telecom operators must prepare for full-service operation from now on.
