As shown in Figure 3, the method that inserts of the embodiment of the invention comprises the following steps:
Step 301, RRU receive data by a group interface.
Wherein have two group interfaces among the RRU at least, have an interface in every group interface at least, every group interface adopts an interface standard, and the kind of the interface standard that at least two group interfaces adopt is no less than two kinds.
The structure of the data that step 302, RRU basis are received is determined the data framing protocol of this The data, and according to the established data Frame Protocol, is determined the interface standard of the group interface employing of these data of reception.
Step 303, RRU adopt the interface standard of determining, insert by a group interface that receives these data.
In the step 302, RRU determines that according to the structure of the data of receiving the mode of the interface standard that a group interface of these data of reception adopts has multiple.Enumerate the mode of several definite interface protocol types below:
Mode one, RRU determine interface standard according to the time span between the head of adjacent two Comma (order) in the data of receiving.
Concrete, preestablish the corresponding relation of time span and data framing protocol and the corresponding relation of data framing protocol and interface standard, time span between adjacent two Comma heads in the data that RRU determines to receive, corresponding relation according to predefined time span and data framing protocol, determine the data framing protocol of the time span correspondence between adjacent two Comma heads, corresponding relation according to predefined data framing protocol and interface standard, determine the interface standard of the data framing protocol correspondence of this The data, and with the interface standard of definite interface standard as the group interface employing that receives these data.
Be 25us such as the time span between the Comma head of IR interface protocol type correspondence, so can the corresponding IR data framing protocol of setting-up time length 25us; Accordingly, the corresponding IR interface standard of IR data framing protocol;
Time span between the Comma head of CPRI interface protocol type correspondence is 66.67us, so can setting-up time length 66.67us corresponding CPRI data framing protocol; Accordingly, the corresponding IR interface standard of CPRI data framing protocol.
Need to prove, the corresponding relation of time span and data framing protocol can be made amendment as required, if change such as the time span between the Comma head of IR interface protocol type correspondence, then can corresponding modify IR interface protocol type time corresponding length.
Mode two, RRU be according to after the Comma head in the data of receiving, and with this Comma adjacent packet in the quantity of SGN, determine interface standard.
Concrete, in the data that RRU determines to receive after the Comma head, and the quantity with SGN in this Comma the adjacent packet, corresponding relation according to predefined quantitative range and data framing protocol, the data framing protocol of the quantitative range correspondence under the quantity of SGN in the packet under determining, corresponding relation according to predefined data framing protocol and interface standard, determine the interface standard of the data framing protocol correspondence of this The data, and with the interface standard of definite interface standard as the group interface employing that receives these data.
In the data after the Comma head, and with this Comma adjacent packet in have a plurality of SGN, namely 1,2,3....., according to the difference of interface standard, the quantity of SGN is also different.
Quantity such as the SGN of IR interface protocol type correspondence is 200, so can setting-up time length range 190～210 corresponding IR data framing protocols; Accordingly, the corresponding IR interface standard of IR data framing protocol can not checked the quantity of SGN certainly, but be checked that last SGN of IR data framing protocol correspondence is 199 last SNG number, just can derive the quantity of SGN according to last SGN, namely 200;

Need to prove that the corresponding relation of quantitative range and data framing protocol can be made amendment as required, if change such as the quantity of the SGN of IR interface protocol type correspondence, quantitative range that then can corresponding modify IR interface protocol type correspondence.
The embodiment of the invention is not limited to above-mentioned dual mode, and other can determine that the mode of interface protocol type all is to use the embodiment of the invention according to the information in the data of receiving.
In specific implementation process, after RRU receives data by a group interface, can go out the RRU frame structure according to the information reverting in the Comma head of data, thereby can finish with the data message of BBU side mutual according to the interface standard of correspondence.
In the step 303, RRU can surpass group earlier synchronously before access, according to the interface protocol type of determining, insert by a group interface module that receives these data after finishing synchronously.
Wherein, the method that the embodiment of the invention inserts can also be embedded in the method for transmitting data, namely insert finish after, just can be according to definite interface protocol type, the group interface by correspondence carries out transfer of data.
Be example so that two group interfaces to be arranged among the RRU, the embodiment of the invention is for high rate data transmission, no matter single, many antennas, two group interfaces among the RRU are configured to different interface standards, namely wherein one group of port is mixed with the IR interface standard, another group interface is mixed with the CPRI interface standard, with the demand of the flexible access of satisfying cascade and not cascade.
Such as: for single antenna 4.9152Gbps transmission, a 4.9152Gbps Ir interface is supported 96 IQ data at most.The spreading rate 1.28MHz of TD-SCDMA system, carrier bandwidths 1.6MHz calculate required IQ number, and A frequency range 20MHz need take 12 carrier waves as can be known, i.e. 12 IQ data; B frequency range 15MHz need take 9 carrier waves, i.e. 9 IQ data; C frequency range TD 10MHz need take 6 carrier waves, i.e. 6 IQ data; C frequency range LTE 20M2A need take 48 IQ data, adds up to 79 IQ data.Because less than 96 IQ data of heap(ed) capacity, so an interface of single antenna just can satisfy practical application request, can satisfy the demands by the configuration of needs modification CA (carrier wave antenna) for the RRU of other speed rates.
Wherein, the IQ data are general names of base band data I road and Q road (two-way is phasic difference 90 degree mutually) data, and the CA data represent with IQ that also revising the CA configuration is exactly to revise IQ data number, makes it satisfy the different rates capacity requirement.
When not considering single antenna cascade application scenarios, the interface that RRU does not connect equipment will be in and idlely not use state, therefore, and when another Interface design is become the CPRI interface standard, just can support two kinds of interface standards to insert main website simultaneously based on same RRU hardware and software platform.When the main website side is the IR interface standard, only need to meet main website with the IR interface of correspondence; If the main website side is the CPRI interface standard, only need to meet main website with the CPRI interface of correspondence, referring to Fig. 4 A and 4B.
If single antenna is supported the cascade scene, if the main website side is the IR standard, meet main website with the IR interface of RRU, and the CPRI interface connects the CPRI interface of next stage RRU, and the like just can realize the cascade of RRU at different levels; If the main website side is the CPRI standard, we just meet main website with the CPRI interface, and the IR interface connects the IR interface of next stage RRU, and the like also can realize the cascade of RRU at different levels, referring to Fig. 5 A and 5B.
Wherein all being that an interface is arranged in the group interface among Fig. 4 A～Fig. 5 B, also might be that two interfaces are arranged in the group interface, shares the mode of cascade such as employing, referring to Fig. 6.
Wherein, mode and the top mode of sharing cascade are similar, just with the data of an interface transmission by two interfaces transmission, after RRU receives the data of two interfaces, can synthesize complete data.
