Wherein, above-mentioned ethernet device can be the equipment of supporting 100,000,000 transmission or gigabit transmission, optical node (ONU, Optical Network Unit) of switch, router, passive optical-fiber network (PON, Passive Optical Network) etc. for example.
MRU, the signal transmission based on the ethernet frame structural bearing of the some transmission medium of reception by can transmitting the Ethernet data service signal, and the signal transmission that receives carried out dissection process, obtain digital baseband signal and the Ethernet data service signal of wherein carrying, then the digital baseband signal that obtains is transformed into the radiofrequency signal of the identical standard at least one road or different systems, and the radiofrequency signal of the identical standard at least one road that conversion is obtained or different systems sends to respectively rf terminal, and (rf terminal is the terminal equipment of supporting the radiofrequency signal transmission-receiving function, comprise mobile phone, this grade of getting online without being tethered to a cable equipment), and with the Ethernet data service signal that obtains carrying sends to ethernet terminal (such as the equipment such as PC for surfing the Net by wired mode) based on ethernet frame format.
Wherein, between MRU and the MEU, between MEU and the carrier dispatching device, can but be not limited to adopt CAT5E UTP cable as transmission medium.
In up link:
MRU, the identical standard at least one road that the received RF terminal sends or the radiofrequency signal of different systems, and the Ethernet data service signal of reception ethernet terminal transmission, and the identical standard at least one road that will receive or the radiofrequency signal of different systems are transformed into digital baseband signal, the conversion digital baseband signal that obtains and the Ethernet data service signal that receives are merged processing, formation is based on the signal transmission of ethernet frame structural bearing, with the signal transmission that the forms some transmission medium by can transmitting the Ethernet data service signal to MEU.
The carrier dispatching device, then what receive that at least one MRU sends carries out dissection process to the signal transmission that receives, obtain digital baseband signal and the Ethernet data service signal of wherein carrying, in the digital baseband signal that obtains, determine carrier signal, carrier signal and the Ethernet data service signal of determining transferred to multi-service expanding element MEU.
Wherein, the carrier dispatching device can obtain the signal transmission based on the ethernet frame structural bearing that MRU sends in MEU, and the carrier dispatching device also can directly be connected with MRU, obtains the signal transmission based on the ethernet frame structural bearing that MRU sends.Preferably, the embodiment of the invention one here, the carrier dispatching device obtains the signal transmission based on the ethernet frame structural bearing that MRU sends in MEU, can save preferably interconnection resource like this.Reducing construction cost.

Step 302 is determined carrier signal in the digital baseband signal that obtains in step 301.
Wherein, if include the radiofrequency signal of multiple different systems in the digital baseband signal that obtains, then in the digital baseband signal that obtains, determine respectively the carrier signal with the radiofrequency signal that belongs to different systems.

The second way: when determining the carrier signal of dispatching and to mate with MRU, the carrier signal of having dispatched is dispatched again.
Step 304 obtains the Ethernet data service signal that ethernet device is sent.
Wherein, the carrier dispatching device can directly obtain the Ethernet data service signal that ethernet device is sent from MEU.A kind of better implementation, the embodiment of the invention here, the carrier dispatching device obtains respectively the Ethernet data service signal that digital baseband signal that MAU sends and ethernet device are sent in MEU.And then digital baseband signal and the Ethernet data service signal that obtains carried out respectively subsequent treatment, can save preferably like this processing resource of system.
Step 305 is dispatched the Ethernet data service signal that obtains, and determines the Ethernet data service signal with corresponding MRU coupling.
Wherein, when the Ethernet data service signal that obtains is dispatched, also can be with the Ethernet data service signal repetitive schedule that obtains.
Step 306 merges processing with carrier signal and Ethernet data service signal after the scheduling, forms the signal transmission based on the ethernet frame structural bearing, then the signal transmission that forms is transferred to corresponding MRU.
In up link:
Step 307 receives the signal transmission based on the ethernet frame structural bearing that at least one MRU sends.
In actual applications, in order to increase the coverage of communication network, can be at different region division MRU, each MRU is connected with MEU by transmission medium, in the indoor distributed system of existing employing repeater as relaying (its structure forms such as Fig. 1), can connect at the most 8 MRU under each MEU, with respect to MEU, each MRU is equivalent to a network interface.Certainly, for each MEU in the indoor distributed system, can not be connected with any one MRU yet, can only connect N MRU yet, wherein, N＜8.
Wherein, the carrier dispatching device can obtain the signal transmission based on the ethernet frame structural bearing that MRU sends in MEU, also the carrier dispatching device can be connected with each MRU, obtains the signal transmission based on the ethernet frame structural bearing that MRU sends.Preferably, the embodiment of the invention here, the carrier dispatching device obtains the signal transmission based on the ethernet frame structural bearing that MRU sends in MEU, like this, can save preferably the interconnection resource of system, reduces Construction Cost.
Step 308 in the signal transmission that receives, is carried out dissection process to its data frame structure, obtains digital baseband signal and the Ethernet data service signal of wherein carrying.
Step 309 is determined carrier signal in the digital baseband signal that obtains, then carrier signal and the Ethernet data service signal of determining transferred to MEU.
Wherein, because when carrying out carrier dispatching, for same carrier signal, can carry out repetitive schedule to it, then distribute to MRU, so in the digital baseband signal that obtains, the carrier signal that also has duplicate allocation, at this moment, in the time of need in the carrier signal of determining, the carrier signal of duplicate allocation being arranged, the carrier signal that repeats is closed the road process.
In like manner, if when in the Ethernet data service signal that obtains, the Ethernet data service signal of duplicate allocation being arranged, need that also the Ethernet data service signal that repeats is closed the road and process.
The method of the carrier dispatching that the embodiment of the invention two proposes here, be fit to be applied in the intensive hot zones that waits of building, can either satisfy communication network cover on a large scale, also can be so that jumbo data adopting the repeater as the transmission in the indoor distributed system of relaying, support simultaneously flexibly networking mode, realize indoor accurate covering, and be convenient to engineering construction, save the cost of engineering construction.Can improve preferably the traffic quality of its overlay area, promote user's perceptibility.
