Method and system for supporting multi-service intelligent access based on radio over fiber technology

Abstract

The invention discloses a method and a system for supporting multi-service intelligent access based on the radio over fiber technology. The method comprises the following steps: the network side adopts an OFDM modulation technology to convert multiple service baseband signals from multiple operators to OFDM modulated baseband signals, and recombine the services to a plurality of multi-service scene groups according to a service deployment strategy; the radio over fiber technology is adopted to convert the OFDM modulated baseband signals to optical millimeter wave signals to be transmitted on a single optical fiber cable; the user side performs photoelectric conversion to the optical millimeter wave signals and respectively provides a 60 GHz all-service access mode and an intelligent multi-service scene access mode. By virtue of the method and the system, multiple services of multiple operators can be efficiently transmitted on the single optical fiber cable; furthermore, the services can be recombined, dispatched and selected according to different service deployment requirements, so as to reduce the total service access cost, simplify the equipment at the user side, improve the anti-jamming capability, the flexibility and the expandability of the system, and promote the user experience.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method and system for supporting multi-service intelligent access based on radio-over-optical technology. Background technique [0002] With the rapid increase in the number of mobile users and the continuous development of new services, higher requirements are placed on the communication system, and the following problems need to be solved urgently: 1) The problem of co-channel interference is serious, and new available frequency resources need to be found; 2 ) Due to bandwidth limitations and transmission rate limitations, it cannot meet the growing needs of users for online viewing of high-definition video, high-speed downloads, real-time games and other services; 3) Different operators target multiple systems (GSM, CDMA, TD-SCDMA, WCDMA , CDMA2000, TD-LTE, LTE-A, etc.) to build access networks separately, resulting in repeated laying of optical fibers, repeated constru...
