Embodiment 1

[0054] Embodiment 1 of the present invention such as Figure 1-2 As shown, a multi-service terminal system oriented to converged access includes a network and a multi-service terminal. The network is based on PON technology, and the multi-service terminal is connected to the rear of the network. The multi-service terminal mainly includes a RoF optical transceiver module 48, frequency division multiplexing With / demultiplexing module 5, Wi-Fi processing unit 50, IP data processing unit 49 and Wi-Fi antenna 17, it is characterized in that RoF optical transceiver module 48 is connected with frequency division multiplexing / demultiplexing module 5; The multiplexing / demultiplexing module 5 is connected with the Wi-Fi processing unit 50 and the IP data processing unit 49 respectively; the Wi-Fi processing unit 50 is connected with the Wi-Fi antenna 17; the RoF optical transceiver module 48 includes an optical fiber input interface 2 and an optical fiber output interface 1, respectivel...

Embodiment 2

[0057] A method of using the above-mentioned multi-service terminal system and utilizing RoF technology to complete downlink transmission information, such as image 3 As shown, the steps are as follows:

[0058] A. The OLT unit receives various services based on the IP protocol from the backbone / MAN, encapsulates part of the Ethernet signals with the Wi-Fi protocol, and frequency-division multiplexes the encapsulated RF signals and Ethernet signals with 1550nm optical wavelengths. Bearer, so that IPTV, Internet and VoIP are transmitted in two signal modes with one wavelength;

[0059] B. The downlink optical signal uses the branching function of the ODN unit to send the downlink signal to each multi-service terminal;

[0060] C. The processing process of the downlink signal when accessing the multi-service terminal includes:

[0061] C1. The photoelectric conversion unit receives the optical signal and converts it into an electrical signal, and sends it to the frequency div...

Abstract

The invention discloses a fusion access-oriented multi-service terminal system which belongs to the technical field of radio over fiber (RoF) and FMC (Fixed Mobile Convergence) network fusion. The system comprises a network and a multi-service terminal, wherein the network is based on a PON (Passive Optical Network) technology; a network background accesses the multi-service terminal; and by adopting the multi-service terminal system and a RoF technology method, transmission of uplink information and downlink information can be completed. By adopting the system, a resource sharing, system-compatible and network fusion multi-information operating platform is established for a multi-service terminal user. The multi-service terminal user can select networks and services as required, fusion of services such as communication, television, net surfing and the like is completed once an optical fiber is accessed, fusion of a wired transmission mode and a wireless transmission mode can be completed, and the user and an operator can make different options flexibly according to different requirements and service qualities.

Description

technical field [0001] The invention relates to a multi-service integrated terminal system for fusion access under the condition of optical fiber access, in particular to a multi-service terminal system for fusion access, which belongs to the field of optical fiber radio and FMC network fusion technology. Background technique [0002] The network architecture of the next generation network (NGN) has always been the focus of the industry. Its concept of openness, convergence, unified control, and IP-centric has been widely recognized by the industry. The goal is to build an IMS-centric network that supports multiple access Open and integrated network with layered structure. Network convergence means that while providing multiple access services, the core network adopts a unified optical network, that is, a layered system architecture with unified IP bearer and unified service control. Converged multi-service terminals allow users to switch between different networks convenie...
