The 4th step: if having only a state to use in associated two side's of the converging panel light mouths of radio frequency unit, so, virtual optical mouth corresponding to these two side's of converging panel light mouths just shines upon with this available side of converging panel light mouth, because the key light mouth can only be carried on the available light mouth.
The 5th step: if two the associated side's of converging equal states of panel light mouth of radio frequency unit can be used, just adopt the mode of periodic polls corresponding to the virtual optical mouth of these two side's of converging panel light mouths, shine upon respectively with these two side's of converging panel light mouths.
The 6th step: shone upon the virtual optical mouth of the side's of converging panel light mouth for each, surveyed whether can receive the MAC packet by the side's of converging baseband board, if can receive the MAC packet that comes from radio frequency unit, judge that then the current side's of the converging panel light mouth that shines upon is exactly the key light mouth, stop poll.
Be example with Fig. 1, if panel light mouth 0 and 1 all is available, virtual optical mouth 0 is done mapping with panel light mouth 0 earlier, judges whether some cycles interior (as 10s) receives the MAC packet that radio frequency unit is sent from panel light mouth 0, if receive then stop poll; If can not receive, then virtual optical mouth 0 is switched to panel light mouth 1 and do mapping, and judge whether (as 10s) receives the MAC packet that radio frequency unit is sent from panel light mouth 1 in the some cycles, if receive then stop poll, otherwise, continue the mapping relations of switching virtual light mouth and panel light mouth in turn, until till the MAC packet of receiving radio frequency unit under some mapping relations.
The 7th step: if the fiber failure at key light mouth place, radio frequency unit will be carrying C﹠amp; The passage of M data switches on the another one optical fiber, and at this moment, the quilt baseband board of the side of converging does not also know that switching has taken place radio frequency unit.When in some cycles (as 10s) when the panel light mouth of current mapping can not receive the MAC packet, if another one light mouth state can be used, the mapping relations of switching virtual light mouth and panel light mouth then, and under new mapping relations, monitor the MAC packet, that is: carried out for the 6th step.
In the above example, supported 3 virtual optical mouths by the side's of converging baseband board, converge the aspect plate and go out 6 light mouths.
Corresponding to said method; the invention provides a kind of baseband board as shown in Figure 2; this baseband board can be used as the baseband board by the side of converging; be used for judging the key light mouth, this baseband board is applicable to the application scenarios that need be mapped to two side's of converging panel light mouths at the two optical fiber scene next ones of dual-mode base station by the side's of converging baseband board virtual optical mouth.Baseband board shown in Figure 2 comprises: judge module 210 and some virtual optical mouths 220, wherein:
