Said higher level's interface processing unit is used to receive the Ethernet data of inflow, and said Ethernet data is stamped VLAN tag V2; Judge whether said Ethernet data needs BBU at the corresponding levels to handle; Handle if desired; Then said Ethernet data is sent to said transfer processing unit; And said VLAN tag V2 is replaced with VLAN tag V1 through said transfer processing unit, through the Ethernet data processing module of this BBU said Ethernet data is handled again; If do not need to handle, then remove said VLAN tag V2 to needing the outflow Ethernet data to send to said subordinate interface processing unit among the said VLAN V2, pass with the Ethernet data that will remove mark V2.
7. like the BBU of the said base station of claim 5; It is characterized in that; Said subordinate interface processing unit also connects next stage BBU or connects backstage control access device, is used for the Ethernet data after the said reduction is sent to next stage BBU or backstage control access device;
Said higher level's interface processing unit also is connected with higher level BBU or RNC, is used to receive the Ethernet data that upper level BBU or radio frequency network control device RNC send over.
8. the BBU of a base station; It is characterized in that; Comprise: at least two different VLANs, one of them VLAN are the VLAN that is used to handle the inner Ethernet data of BBU at the corresponding levels, are labeled as V1; Another VLAN is the VLAN that is used for Ethernet data between the treatments B BU cascade, is labeled as V2; Said VLAN V2 comprises: higher level's interface processing unit, subordinate's interface processing unit and belong to the said transfer processing unit that is used to handle the VLAN V1 of the inner Ethernet data of BBU at the corresponding levels and is used for the VLAN V2 of Ethernet data between the treatments B BU cascade simultaneously, wherein:
The said VLAN V1 that is used to handle the inner Ethernet data of BBU at the corresponding levels; The Ethernet data that is used for being used to handling VLAN the needs outflow of the inner Ethernet data of BBU at the corresponding levels marks V1, the Ethernet data of the said V1 of being marked with is sent to the transfer processing unit of BBU at the corresponding levels;
After said transfer processing unit replaced with mark V2 with said mark V1, the Ethernet data that sends to the said V2 of being labeled as sent to said higher level's interface processing unit;
Said higher level's interface processing unit is used for the said VLAN V2 that is used for Ethernet data between the treatments B BU cascade is removed this Ethernet data of reduction with said mark V2, and the Ethernet data after the said reduction is sent.
9. like the BBU of the said base station of claim 8; It is characterized in that; Said subordinate interface processing unit also connects next stage BBU or connects backstage control access device, is used to receive the Ethernet data that said next stage BBU or backstage control access device send over;
Said higher level's interface processing unit also is connected with higher level BBU or RNC, is used for the Ethernet data after the said reduction is sent to said upper level BBU or RNC.
