In order to make the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, the present invention is described in further detail, and obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making all other embodiment that obtain under creative work prerequisite, belong to the scope of protection of the invention.
The embodiment of the present invention is applicable to C-RAN framework, and Fig. 2 shows the C-RAN configuration diagram that the embodiment of the present invention provides, and wherein, only shows 3 BBU, when realizing, is not limited to 3 BBU.Under C-RAN framework, master control borad in BBU and baseband board are connected to inner exchanging chip by ethernet link respectively, each inner exchanging chip is connected with external switch by ethernet link, and like this, inner exchanging chip and external switch are interconnected by these boards.In addition, the master control borad in BBU is also connected to each baseband board by iic bus, and master control borad can pass through the different baseband board of iic bus addressing, and reads and writes the hardware register in each baseband board.
In the embodiment of the present invention, for each BBU in baseband pool distributes virtual frame number, the virtual frame number distributing for each BBU can be in this baseband pool this BBU of unique identification, make each board in BBU can be according to the virtual frame number configuration of IP address of distributing to this BBU, guaranteed the uniqueness of IP address in this baseband pool, thereby solved under C-RAN framework the problem of the IP address conflict of the board in baseband pool.
Below in conjunction with accompanying drawing, the embodiment of the present invention is specifically described.
Framework based on shown in Fig. 2, Fig. 3 shows the IP address configuration schematic flow sheet that the embodiment of the present invention provides.The method can comprise:
Step 31: the master control borad in the BBU of baseband pool to be accessed, be received as the virtual frame number that this BBU configures, described virtual frame number is for the described BBU of unique identification baseband pool.
The virtual frame number is here controlled information, can, by artificial pre-configured mode or the mode being numbered according to the predefined rule of system, be BBU configuration virtual machine frame number.In this process, need to guarantee that described virtual frame number is unique existence, that is to say, for the virtual frame number of described BBU configuration and the virtual frame number of other BBU in baseband pool can not repeat.
During specific implementation, when needs access baseband pool by BBU, can connect master control borad by manual type, and can be on-the-spot in BBU configuration by operating personnel, by man-machine interface, the virtual frame number distributing for this BBU being configured to this BBU upper, can be also this BBU configuration virtual machine frame number by remote control equipment.
Step 32: master control borad is configured to respectively each baseband board in BBU by virtual frame number.
During specific implementation, master control borad can pass through iic bus, virtual frame number is configured to respectively in the hardware register of each baseband board in BBU.In this process, master control borad adopts iic bus to be configured each baseband board.
Step 33: master control borad triggers BBU and resets, so that the master control borad in BBU and each baseband board are according to described virtual frame number configuration of IP address.
During specific implementation, after master control borad triggers BBU and resets, each board in BBU (comprising master control borad and baseband board) is according to the information configuration IP addresses such as virtual frame number in hardware register separately.This IP address is Ipv4 address.The method of concrete configuration IP address can adopt existing method, such as, can generate IP address according to following formula:
(10<<24|0<LEssT.LT ssT.LT16| frame number (0) <<12| slot number <<8|192| processor number)
Wherein, 10 in " 10<<24 " is artificial regulations, and 10<<24 is about to 10 and moves to left 24, forms highest byte 0x0a; In " 0<<16 " 0 is artificial regulation, 0<<16 is about to 0 and moves to left 16, form second byte 0x00: " frame number (0) <<12| slot number <<8 " represents: frame number is defaulted as 0, move to left 12, form the high 4bit of the 3rd byte, slot number moves to left 8, forms the low 4bit of the 3rd byte; In " 192| processor number " 192 adds processor number, forms the 4th byte.According to above-mentioned formula, obtain the value of four bytes of IP address, and do displacement and get or operate, just formed the IP address of nybble.
Therefore because the computational methods of IP address are same as the prior art, accessing the software that in software that the BBU of baseband pool uses and prior art, BBU is used can be consistent, and does not need existing BBU to transform.
After this, BBU can be connected into baseband pool.Now, in baseband pool, the virtual frame number of each BBU is different, can not conflict in IP address.
By above description, can find out, owing to configuring different virtual frame numbers for each BBU, when BBU access baseband pool, the method providing according to the embodiment of the present invention resets while restarting, each board is according to unique IP address of the virtual frame number structure in the hardware register of self, thereby each board that makes to access the BBU in baseband pool possesses unique IP address, avoided the IP address conflict problem between BBU board, and then avoided the problem of the communication contention aware that causes because of IP address conflict.
Because described virtual frame number is artificial configuration or configures by remote control equipment, in layoutprocedure, same virtual frame number may be configured to two or more BBU, in order to address the above problem, Fig. 4 shows another kind of embodiment of the present invention, for solving under C-RAN framework, the problem of virtual frame number conflict during configuration of IP address, can realize as follows:
