Step 104:, manage the RRU in the described distributed base station according to RRU in the described distributed base station and local topological relation.
The method that the embodiment of the invention provides, by obtaining the device id that RRU generates according to the device id generation strategy in the distributed base station, bonding apparatus ID generation strategy, determine RRU and local topological relation in the distributed base station, realize obtaining automatically topological relation, adopt the topological relation that obtains again, RRU in the distributed base station is managed, solve the artificial high problem of manual configuration topological relation O﹠M cost in the prior art, reduced O﹠M cost, and realize simple.
Below embodiments of the present invention is further illustrated:
Fig. 2 is the structural representation of distributed base station in the application example of the present invention.Distributed base station shown in Figure 2 comprises BBU and a plurality of RRU, and wherein BBU mainly comprises main control unit and a plurality of baseband processing unit, and wherein baseband processing unit comprises a plurality of light mouths, and be connected by CPRI light mouth between the RRU, wherein a plurality of RRU can cascade together.
Fig. 3 is the method application example schematic flow sheet of managing distributed base station provided by the invention.In structure shown in Figure 2,, should specifically comprise with the method for example in conjunction with method shown in Figure 1:
Step 301:BBU obtains the device id generation strategy.
Concrete, should comprise with device id generation strategy in the example:
The first order RRU device id that is connected with each Base Band Unit light mouth of initialization at first after BBU powers on, wherein the length of this device id is 16bit, the level chain store that wherein low 8bits is used to indicate RRU.After to each initialization, the size of the device id that BBU is initial can be identical, also can be different, the level chain store all is 0, and the numerical value change strategy of indication device id is for increasing progressively 1 in the device id generation strategy, and promptly device id increases by 1, and the level chain store just increases by 1, increase progressively 1 after being transferred to next RRU again, send out by the CPRI control word of arranging.
For example, the device id that each first order RRU can be set all is 100000000; The device id of second level RRU all is 100000001, and the level chain store of expression second level RRU is 1; The device id of third level RRU all is 100000010, and the level chain store of expression third level RRU is 2; And the like.
Again for example, the device id that first order RRU can be set is distributed as 100000000 and 10000000000; The generation method of the device id of the RRU of cascade is similar to last example, repeats no more.
Step 302:BBU is to RRU transmitting apparatus ID generation strategy.
Concrete, BBU sends to RRU in the distributed base station by the CPRI control word with the device id generation strategy.
Step 303, RRU adopt the device id generation strategy to generate the device id of self.
Concrete, the RRU of the first order is receiving the device id generation strategy that BBU sends, with the device id of the device id in the device id generation strategy as self, and be that device id is increased by 1, and be delivered to next stage RRU by the CPRI control word, the RRU of subordinate is fetch equipment ID successively, and writes down current level chain store, after increasing progressively device id again and be delivered to next stage again; And the like.
The device id of step 304:RRU notice BBU self.
Concrete, in order to save the exchange flow process, should use the device id that passes through to set up request transmission self in the example to BBU initiation communication link, under the prerequisite of realization announcement apparatus ID, the transmission of follow-up is convenient in the foundation that initiation simultaneously communicates to connect.
Step 305:BBU obtains the topological relation of BBU and RRU according to device id and the device id generation strategy of RRU.
Concrete, BBU obtain local reception described distributed in the Base Band Unit of device id of RRU and the light mouth of this Base Band Unit, obtain the light mouth of the local Base Band Unit that is connected with RRU in the described distributed base station and this Base Band Unit; With the numerical value of described RRU device id and described device id generation strategy relatively, obtain the cascade position of this RRU on the light mouth of the Base Band Unit that is connected with RRU in the described distributed base station and this Base Band Unit, thereby obtain the topological connection relation of RRU and BBU.
Wherein should be with in the example and since in the device id generation strategy numerical value change strategy of indication device id for increasing progressively 1, if then among the low 8bits of device id numerical value be 1, represent that then the RRU of this device id correspondence is positioned at the second level.
Step 306:BBU and RRU establish a communications link.
Concrete, because BBU has got access to the device id of RRU, can finish the foundation of communication link, the method that establishes a communications link in the prior art all is applicable to this step, repeats no more herein.
Step 307:RRU adopts to communicate to connect to BBU and reports its other resources information and ability information.
Wherein resource information can be following one or more: equipment vendors' identification information, version information, hardware specification; Ability information is radio-frequency channel ability and/or the frequency range ability that RRU self supports.
Equipment entity and the topological connection relation of the information structuring RRU that step 308:BBU reports according to RRU.
Wherein topological connection relation is interface board frame-saw groove, light mouth and the cascade that RRU is connected with BBU.
Behind equipment entity that obtains RRU and topological connection relation, BBU reports equipment entity and the topological connection relation of RRU to the backstage, thereby make the backstage construct RRU resource model and topological connection relation, thereby finish RRU equipment from the process of finding according to above-mentioned information synchronization.
Need to prove that device id generation strategy provided by the invention is not limited to this, is rule as long as be in the device id numerical value of cascade state generation, and this rule BBU also knows, both can know the topological relation of RRU, and establish a communications link again, thereby RRU is managed.For example, BBU or other equipment are that the light mouth of each Base Band Unit of BBU disposes a plurality of device ids respectively, are numbered 1～50 respectively, and the device id generation strategy is selected the device id of n device id for self for n RRU on this light mouth, n=1 wherein, 2 ... 50.In actual applications, the value of n should be greater than level chain store maximum in the distributed base station.
The method that application example of the present invention provides can be found the RRU equipment that BBU connects automatically according to the network topology relation, and automatic apparatus for establishing resource and topological connection relation, to guarantee to satisfy the requirement of SON self-organizing network.
