By Fig. 4 and Fig. 5 as seen, in the communication network of supporting FMC, when customer traffic transmitted by mobile communications network, this user data failed to be convened for lack of a quorum and realizes the termination of wireless transmission protocol by the wireless transmission protocol processing unit, and was distinguished fixed-line subscriber data flow and wireless user data stream; Described fixed-line subscriber data flow and wireless user data flow point are not sent to and fixing insert processing subsystem and the wireless access processing subsystem is handled, and finish the fixed-line subscriber data of processing and mobile user data can be respectively by eating dishes without rice or wine and service cable is sent to user terminal.
Referring to Fig. 6, Fig. 6 is GANE and the supporting terminal traffic face logical architecture figure thereof of the support FMC of the embodiment of the invention, has only expressed the device of being paid close attention to when being described at Fig. 6 in this structure chart.Among Fig. 6, at down direction, GANE at first receives the information flow of base station controller, and this information flow is realized the termination of wireless transmission protocol through the wireless transmission protocol processing unit, and distinguishes fixed-line subscriber data flow and wireless user data stream.
Wherein, wireless user data stream is handled after antenna is launched away by the base station radio passage, and is received by terminal wireless passage (generally including RF processing unit and end side baseband processing unit in the continuous end side); Afterwards, the terminal wireless passage carries out radio channel to the received signal to be handled to generate base-band data signal, again through information source data processing unit processes to generate speech or data flow.The fixed-line subscriber data flow then connects the information source data processing unit directly be sent to user terminal by user logic, through information source data processing unit processes to generate speech or data flow.The data flow trend of up direction is opposite with the data flow trend of down direction, does not repeat them here.
As seen from Figure 6, in GANE, for down direction, wireless user data can be handled after eat dishes without rice or wine to send to user terminal by traditional radio channel; Also can connect by user logic and send to user terminal in the mode of wired connection.The up direction data flow is opposite with the down direction data flow.
Need to prove: the data stream format of A, B and C, D present position is identical among Fig. 6, if A different with the data stream format of C present position (respectively at uplink and downlink), then need on B and D link corresponding, do corresponding data format adaptive (can realize in base station side, also can realize) in end side.
Referring to Fig. 7, Fig. 7 is the GANE logical architecture figure of second embodiment of the invention.Identical with Fig. 4, GANE shown in Figure 7 also by public parton system, fixingly insert processing subsystem and these 3 parts of wireless access processing subsystem are formed.And GANE also can communicate by letter with MT, GT, FT.

Referring to Fig. 8, Fig. 8 is the physical structure figure of GANE among Fig. 7.Corresponding with Fig. 7, the physics realization of GANE in Fig. 8 also partly is made up of public part, fixing access part and wireless access.
Wherein, public part is made of wireless transmission protocol disposable plates, master clock power board, public veneer.Particularly, the host-host protocol disposable plates is the physics realization carrier of wireless transmission protocol processing unit.The master clock power board in addition, for the data communication between the convenient realization service board, has been introduced the function of data switching center in order to realize the function of master control, clock and operating maintenance module at the master clock power board from the physics realization angle.
Generally, data switching center and master control, clock and Operation and Maintenance Unit are arranged at same veneer jointly; But when working as a lot of and disposal ability of the veneer quantity of being served and having relatively high expectations, also data switching center can be separately set on the veneer.In addition, the function of wireless transmission protocol disposable plates can also be moved on in the master clock power board and realize, fall cost by reducing veneer quantity.
The fixing part that inserts is made of a plurality of deciliters road plates, and deciliter road plate is used to realize a plurality of users' up functions such as driving of closing road, descending shunt, external coffret; When the data format of base station and end side not simultaneously, also to finish the Data Format Transform processing capacity, its main purpose be with user be granularity with data to the target terminal user transparent transmission.Need to prove that the suggestion of coffret between deciliter road plate and the user terminal is with the physical bus interface between terminal wireless passage and the information source data processing unit as shown in Figure 6; Certainly, in actual applications, also can use other standard physical interface (as: Serdes, xDSL, POTS, VDSL, FE/GE, RS485 etc.), other special host-host protocol (as: standard agreement or self-defined host-host protocols such as HDLC, IP, ATM) again can also superpose.
Wireless access function entity among Fig. 8 is used to realize that the wireless data framing is to all functions between the antenna, its physical structure and traditional base station are as broad as long, generally constitute, also support the access of RRU simultaneously by LTE Baseband Processing Unit, base band radio frequency interface plate, radio receiving-transmitting unit (containing power amplifier) and duplexer.
In addition, wireless disposable plates such as deciliter road plate and LTE Baseband Processing Unit are because basic identical with the interface requirements of backboard, be easy to accomplish the compatible design in groove position, be put in the machine frame, by supporting that mixed insertion farthest utilizes the groove bit space so deciliter road plate and wireless disposable plates are easy to concentrate.When needing more LTE Baseband Processing Unit and deciliter road plate in the configuration, can dispose a plurality of professional frames.
Need to prove: the fixed access subscriber quantity that inserts when needs is seldom the time, can remove special deciliter road plate, directly panel (as wireless transmission protocol disposable plates, master clock power board, LTE Baseband Processing Unit etc.) interface inputoutput data by hanging over the base band frame veneer in the data switching center.
Referring to Fig. 9, Fig. 9 is the user terminal structure figure of one embodiment of the invention; This user terminal realizes that by introduce a fixed access subscriber line on traditional portable terminal this fixed access subscriber line is used for directly transmitting the radio base band data.
Particularly, user terminal shown in Figure 9 is made of RF processing unit, end side baseband processing unit, information source data processing unit, master control and Operation and Maintenance Unit and other peripheral hardware (as: display screen, keyboard, loud speaker, pick-up etc.) in the end side.Wherein, RF processing unit links to each other successively in information source data processing unit and end side baseband processing unit, the end side; Master control and Operation and Maintenance Unit link to each other with peripheral hardwares such as information source data processing unit, end side baseband processing unit, display screen, keyboards respectively; The information source data processing unit also links to each other with peripheral hardwares such as fixed access subscriber, loud speaker, pick-ups.
Particularly, master control and Operation and Maintenance Unit are used to realize the control and management of interior all functions module of user terminal and resource.The physical port and the form that it should be noted that the fixed access subscriber line need and the corresponding supporting use of GANE.
At down direction, the information source data processing unit both can receive user's face base band data that RF processing unit in antenna, end side (realizing functions such as filtering, low noise amplification, down-conversion, analog to digital conversion and Digital IF Processing), end side baseband processing unit (realization separate be in harmonious proportion function such as decoding) are sent, and also can directly receive not user's face base band data of process radio channel processing by service cable.If use the received data format difference of above-mentioned dual mode, the information source data processing unit needs earlier the fixing user data that inserts to be carried out format conversion, and definite more afterwards road input wherein is as the data source of subsequent treatment.For voice data, realize exporting by loud speaker after voice signal is handled at the information source data processing unit; For data service, after the management of master control and Operation and Maintenance Unit and control, directly deliver to display screen through the data flow after the information source data processing unit processes and show or deliver to other peripheral hardware.Upstream data flows to process and downlink data, and to flow to process opposite.
As seen, user terminal shown in Figure 9 both can directly receive wireless signal by antenna, also can directly receive the customer traffic that does not transmit through wireless channel that the base station is sent here by service cable.When concrete the application, at mobile scene, user terminal can insert by wireless mode; At fixed scene, user terminal then can switch to the service cable access way, can also further turn off the power supply of wireless processing section parallel circuit.
Referring to Figure 10, Figure 10 is the user terminal structure figure of another embodiment of the present invention.Compare with Fig. 9, user terminal shown in Figure 10 is just removed the function about wireless processing section branch (comprising RF processing unit and end side baseband processing unit in the end side).
By Fig. 9, only need on the basis of traditional mobile subscriber terminal, to introduce a fixed access subscriber line, just can support fixing the access.In fact, described fixed access subscriber line is exactly service cable usually.
By the above as seen, for GANE, only need in traditional base station, insert some and relate to fixing veneer that inserts and upgrading control maintenance software, just can increase the support that inserts fixing.This makes that mobile operator does not need also to make fixed operator can access because of introducing to move and insert the FMC business income of bringing for supporting fixing the access to lay the network of throwing the net in addition, further can also satisfy fixing dilatation and the evolution requirement that inserts.
By the above as can be seen, the system that the embodiment of the invention provided, device and data transmission method all can be realized FMC.
