Embodiment Construction

[0026] NFV (Network Function Virtualization, Network Function Virtualization) was proposed and regulated by ETSI (European Telecommunications Standards Institute, European Telecommunications Standards Institute), aiming to use general-purpose hardware (servers, storage, switches, etc.) as much as possible as the network hardware platform (resource pool) , the functions are implemented by software as much as possible, thereby eliminating the dependence of functions on hardware, enabling virtualization of the network, and ultimately reducing the cost of network construction and maintenance, and network functions can dynamically adapt to emerging new business requirements. It can be seen that NFV creates favorable conditions for the integration of fixed network and mobile network, making it possible to realize a functional system that meets the needs of both fixed network and mobile network on a common hardware platform. Therefore, for the access network, NFV can be used Technolog...

Abstract

The invention discloses fixed and mobile broadband fused access network architecture. The architecture comprises a central office, multiple wavelength division multiplexing loops and a PON (Passive Optical Network) access module. The central office comprises a plurality of upper linkage units and a resource pool. Each wavelength division multiplexing loop comprises a loop local end unit and multiple loop far end units. The PON access module comprises an ODN and ONUs. The upper linkage units are communicated with a core network. The resource pool virtualizes functions such as an OLT (optical line terminal), CPE (Customer Premise Equipment), a BAS (Broadband Access Server) and a BBU (Building Baseband Unit) based on an NFV (Network Function Virtualization) technology. Each wavelength division multiplexing loop is used for realizing optical transmission between the PON access module, base stations and big customers, and the central office. The base stations and the big customers are directly connected with the loop far end units. The ONUs are connected with fixed broadband users or base stations and RRUs of mobile broadband and access the fixed broadband users and the base stations and RRUs to the network. Optical transmission between the loop far end units and the ONUs is realized through the ODN. According to the architecture, the fixed broadband and mobile broadband fused sharing is realized in the network resource aspect; the low-cost and multi-access advantages of the PON technology are exerted fully; and the low-cost, high-capacity, high-sped and high- survivability transmission is realized.

Description

technical field [0001] The invention relates to the field of metropolitan access, in particular to a fixed and mobile broadband fusion access network architecture. Background technique [0002] Under the requirements of the continuous development of the Internet, cloud computing, and the Internet of Things, the "Broadband China Strategy" raises fixed broadband and mobile broadband access to the same status as infrastructure such as water, electricity, and gas. With the continuous popularization and function upgrade of smart terminals, as well as the full-service operation of operators, the synergy between fixed network and mobile can better meet the needs of users and improve user experience. [0003] For a long time, fixed broadband and mobile broadband have been independent of each other, and the two networks each form a "chimney" architecture ( figure 1 shown). At present, although fixed broadband and mobile broadband services have been integrated through "package packa...
