Description
Technical field
The present embodiments relate to communication technical field, more particularly, to a kind of signal co-cable transmission method and system.
Background technology
For the transformation of domestic broadcasting and TV bilateral network, renovation technique commonly used at present is CM (Cable Modem, electricity
Cable modem) or EOC (Ethernet Over Cable, Ethernet cable), or two kinds of technology depositing.
Wherein, CM technology is to access standard based on DOCSIS to carry out bandwidth access with cable modem for access way
The technology of business, is referred to as CM signal by the signal that CM technology is transmitted.EOC technology is based on wired TV coaxial cable net
Using the access technology of Ethernet protocol, eoc signal is referred to as by the signal that EOC technology is transmitted.CM technology and EOC at present
The system equipment framework of technology is usually to arrange ustomer premises access equipment, such as the ustomer premises access equipment CM in CM system in user side
Ustomer premises access equipment CNU (Cable Network Unit, end in (Cable Modem, cable modem) and EOC system
End equipment coax network unit).These ustomer premises access equipments for example can be integrated in the Set Top Box of family expenses, with wired or nothing
Line communication mode is communicated with the user terminal in user family, provides online clothes for the user terminal such as mobile phone or computer
Business.Headend equipment is also included, such as CMTS (the Cable Modem Temination in CM system in system equipment framework
System, Cable Modem Terminal System) and EOC system in CLT (Communication Line Terminal, with
Shaft cable line terminal).Headend equipment, generally as Distribution Center, is connected by cable with multiple ustomer premises access equipments.For example, CMTS
In the collecting and distributing area of network that certain cell can be arranged on this two equipment of CLT, set with the user side in each user family by cable
Standby connected.
Because the laying mode of cable run is different, it is possible that between CMTS and CLT and its respective CM and CNU altogether
Carry out the phenomenon of signal transmission with cable.In CM technology and EOC technology and in the case of depositing, there is CM signal and eoc signal altogether
The problem of cable transmission, because CM upward signal frequency range is 5-65MHz, eoc signal frequency range is 7.6-65MHz, two kinds
There is overlapping situation in signal spectrum, in order to solve this problem, domestic broadcasting and TV when carrying out EOC communication protocol definition, to EOC
Signal transmission defines two kinds of mode of operations, and a kind of is basic model (operating frequency range is 7.6-30MHz), and a kind of is extension
Pattern (operating frequency is 7.6-65MHz), when CM signal and eoc signal co-cable transmission, eoc signal is operated in basic model,
Namely operating frequency range is 7.6-30MHz, and CM upward signal frequency range is 30-65MHz.
Prior art for user terminal provide service on net when flow process be usually：When user terminal is sent out to ustomer premises access equipment
When playing online request, request of surfing the Net is transmitted to headend equipment by ustomer premises access equipment；Headend equipment is this online request estimation online
Required bandwidth demand, bandwidth demand specifically includes the time span of required spectral band quantity and use, i.e. mini-slot；Before
End equipment combines the frequency spectrum resource having distributed to other headend equipments itself being connected, new for current online request distribution
Spectral band and mini-slot；The spectral band distributing and mini-slot are passed through channel change message by headend equipment, are sent to user side and set
Standby, carry out signal with headend equipment and interact based on the spectral band distributing and mini-slot for ustomer premises access equipment, thus being user terminal
Service on net is provided.
In CM technology and EOC technology, headend equipment all carries out spectral band resource in itself given frequency range
Distribution.It can be seen that, signal spectrum is simply carried out frequency division multiplexing by prior art, when the load imbalance of CM system and EOC system,
Do not make full use of frequency spectrum resource and the actual demand of user can not be met well.
