Table 1 router-table structure example
Step 502, BBU and RRU, according to the corresponding relation set up, sends and receives carrier wave on the AXC of corresponding Ir optical port
Data.
Specifically, in the upstream direction, RRU according to the corresponding relation set up in step 501 by the number of each for each carrier wave path
It is transferred to BBU according to by the AXC in its corresponding Ir optical port, BBU is according to the corresponding relation set up in step 501 by Ir optical port
The data that the data that each AXC carries is mapped as its corresponding carrier wave path is processed；In the downstream direction, BBU is according to step
The data of each for each carrier wave path is transferred to RRU, RRU by the AXC in its corresponding Ir optical port by the corresponding relation set up in 501
According to the corresponding relation set up in step 501, the data that each AXC in Ir optical port carries is mapped as its corresponding carrier wave path's

When being realized by BBU and RRU shown in Fig. 6 and Fig. 7, in BBU, Ir buffer unit is used for caching Ir optical port to be owned
The data of AxC, carrier wave buffer unit is used for caching all carrier data.Wherein, c0 buffer is used for caching carrier wave 0 and owns
The data of path, the rest may be inferred for other buffer, and routing table memory module is used for storing routing table, and routing table can be as needed
Configuration, route control unit is used for controlling the route between the AxC that the carrier processing unit of RRU and Ir are carried.
Specifically, in RRU, in down direction, in Ir seam, each the AxC data order in Ir is buffered in Ir first
In buffer unit, the address of a fixation in each No. AxC corresponding Ir buffer unit, then route control unit read road first
By table, obtain the Ir AxC numbering corresponding to each carrier wave path, gone as the address of Ir buffer unit with this Ir AxC numbering
Read data, finally according to carrier wave path numbering, the corresponding of carrier wave buffer unit that the data of reading is written to below is stored position
Put.In up direction, first at carrier processing unit interface, each carrier wave path data order is buffered in buffer,
Each carrier wave path corresponds to the address of a fixation in carrier wave buffer unit, and then control module reads routing table first, obtains
Each carrier wave path numbers, and goes to read data, last root as the address of each carrier wave buffer unit with this carrier wave path numbering
According to Ir AxC numbering, the data of reading is written in the storage location of corresponding AXC in Ir buffer unit, after route, schematic diagram is such as
Shown in Fig. 8.
In BBU, in up direction, in Ir seam, each the AxC data order in Ir is buffered in Ir caching first single
Unit in, the address of a fixation in each No. AxC corresponding Ir buffer unit, then route control unit read routing table first,
Obtain the Ir AxC numbering corresponding to each carrier wave path, go receive data with this Ir AxC numbering as the address of Ir buffer unit
According to the data of reading being written in the corresponding storage location of carrier wave buffer unit below finally according to carrier wave path numbering.
In down direction, first at carrier processing unit interface, each carrier wave path data order is buffered in buffer, each
Carrier wave path corresponds to the address of a fixation in carrier wave buffer unit, and then control module reads routing table first, obtains each
Carrier wave path numbers, and goes to read data as the address of each carrier wave buffer unit with this carrier wave path numbering, finally according to Ir
The data of reading is written in the storage location of corresponding AXC in Ir buffer unit AxC numbering.In BBU, in guarantee system
Carrier wave delete when building, distributing carrier wave will not be impacted it is preferable that further including to process as follows：
Step 503, when deleting carrier wave, deletes the corresponding corresponding relation of carrier wave；When newly-built carrier wave, the distribution free time
AXC is used for carrying the data of this newly-built carrier wave, and sets up between each paths of this newly-built carrier wave and the AXC of carrying corresponding data
One-to-one relationship.
This step is used for the process carrying out deleting carrier wave and newly-built carrier wave, when deleting carrier wave, will preserve and this carrier wave phase
The corresponding relation closing is deleted.Specifically, can directly in the routing table of BBU and RRU by respective table entry deletion, or can also
It is invalid to be set to the valid flag of corresponding route when routing table includes list item valid flag.
In newly-built carrier wave, determine the AXC of current idle, distributed the data being used for carrying newly-built carrier wave, and set up
The related corresponding relation of this carrier wave.Specifically, can directly in the routing table of BBU and RRU by newly-built routing iinformation, or,
Can also determine that valid flag is arranged to invalid route when routing table includes list item valid flag, using new road
This invalid route entry by information can be caused to cover.
So far, the method flow in the present embodiment completes.After processing by the way, by AXC and carrier wave path pair
The setting that should be related to, can easily utilize idle Ir optical port resource allocation to new carrier wave, it is possible to achieve discontinuous in Ir
RRU carrier data is transmitted on the AxC of free timeslot, improves the efficiency of transmission of Ir optical port.When newly-built or delete carrier wave when, also will not
The transmission relation of existing carrier wave impacted, it is to avoid the stringent synchronization of BBU and RRU.
