Embodiment tetra-
Fig. 4 is according to the flow chart of the self-discovery method of the distributed base station of the embodiment of the present invention four, this distributed base station comprises BBU and RRU, wherein, the resident SON of having manager (SON Manager) and reside in respectively the BBU side SON agency (SONAgent) of BBU side internal element and reside in the RRU side SON Agent of RRU side on BBU side internal element.SON is third generation mobile Long Term Evolution (Long Term Evolution, abbreviation LTE) a kind of brand-new network management theory in system, its core concept is to realize some autonomic functions of wireless network, reduce manual intervention, reduce operator's operation cost, improve operating efficiency, improve user's impression.As shown in Figure 4, said method comprising the steps of:
Step S402, SON Manager carries out initialization.
When receiving BBU, SON Manager powers on after message, SON Manager carries out initialization preparation, comprising: obtain the configuration status of each veneer of BBU side internal element, open cyclic polling veneer plate state timer, open the timer that cycle detection does not configure veneer.
Wherein, veneer configuration status is that mode by query configuration status data obtains.SON Manager is the veneer configuration status that inquires BBU configuration status data by the subrack administration module of BBU from database configuration table.When the database configuration table in subrack administration module changes, this subrack administration module is by the trigger notice SON Manager of registration table.
Step S404, SON Manager obtains and does not configure BBU single board information.
When the timer of cyclic polling veneer plate state is to constantly, SON Manage obtains the veneer plate state of BBU from BBU.Specifically, obtaining veneer plate state can obtain by two kinds of modes: a kind of mode is that veneer reports its plate state by heartbeat mode, if SON Manager can receive the veneer heartbeat message that the heartbeat reporting module of BBU reports, according to received heartbeat message, judge whether its plate works, and then obtain veneer plate state; Another kind of mode is that the message that the subrack administration module by BBU provides obtains plate state, specifically, be by the interface of cyclic polling subrack administration module, by subrack administration module inquiry plate status data, can get the plate state of all veneers of BBU side internal element.
When receiving the response message of subrack administration module or heartbeat reporting module, SON Manager receives after the plate state of veneer, upgrade the plate state of BBU side interior veneer, and by relatively plate state and its corresponding veneer configuration status of veneer obtain not configuration information of veneer.If veneer does not also obtain hardware information, by hardware information reporting module, inquire about hardware information, thereby obtain the hardware information of BBU.
Step S406, carries out adaptive optical mouth rate-matched.
When the SONAgent of BBU receives BBU, power on after message, the unlatching cycle is obtained the timer that does not configure RRU, and carries out adaptive optical mouth rate-matched.BBU side SON Agent obtains the light mouth speed list of BBU side internal element, reports not the RRU of configuration and the light mouth rate information of BBU side internal element to SON Manager, and the cycle carry out the driving of light mouth rate adaptation, with first order RRU light mouth rate-matched.The process of the adaptive optical mouth rate-matched of concrete BBU side SONAgent and RRU side SONAgent has detailed explanation at embodiment five places, repeats no more herein.
Step S408, obtains and does not configure RRU single board information.
The BBU side SONAgent cycle gets all RRU of configuration single board information of hanging under BBU.When the cycle obtain do not configure RRU timer to constantly, BBU side SON Agent and each RRU side SON Agent are mutual, obtain the configuration information of RRU.Specifically, BBU side SON Agent is after the request of inquiry RRU configuration that receives SON Manager, judge whether light mouth is configured to ring or whether actual connection is ring, and judge that by not configuring the detection of RRU whether RRU is for not configuring, if RRU, for not configuration, obtains and does not configure RRU single board information.
Wherein, the detection that does not configure RRU is by the loop detection in logic hardware control word (LoopTest) result, checks the link break-make situation of hanging RRU at different levels under each light mouth in BBU veneer, and this light mouth actual link Cheng Huan whether.If RRUID be 255 and LoopTest result for logical, so, can think that this RRU has connected, but not configuration; If RRU ID be 255 and LoopTest result obstructed, so think that this RRU does not connect, therefore do not need self-discovery yet.Wherein, RRU ID is this RRU of 255 expressions in configuration status not, that is to say that BBU is when management RRU ID, and the RRU that initial default RRU ID is 255 is in configuration status not.
Step S410, reports and does not configure RRU single board information.
BBU side SON Agent reports and does not configure RRU single board information to SON Manager.RRU side SON Agent will not configure RRU single board information by BBU side SON Agent and will report SON Manager.
Step S412, SON Manager processes reporting information.
SON Manager receives after reporting information, distributes virtual RRU ID and upgrades topological sum route.Specifically, when SONManager receives that, after the message that does not configure RRU single board information that BBU side SONAgent reports, record does not configure RRU single board information, and by RRU ID administration module, route and virtual RRU ID is set.
Wherein, virtual RRU ID be for unique identification RRU in communication network Shang address, the management of virtual RRU ID is mainly reflected in the management of virtual RRU ID state table.After receiving the not configuration RRU message that BBU side SON Agent reports, more current reported result and last time reported result, if the RRU reporting last time not in the list reporting specifically, illustrates that RRU has been configured or RRU is pulled out, need to delete corresponding RRU ID.If the RRU reporting is not specifically in the list of finding last time, explanation is that this RRU is newfound, need to increase RRU ID newly.
Step S414, SON Manager reports and does not configure BBU single board information and do not configure RRU single board information to webmaster.
SON Manager, when receiving the message of periodic report timer, by the configuration information reporting module of BBU, collects the not configuration BBU single board information that not configuration and hardware information got and does not configure RRU single board information, and being reported webmaster.
Specifically, SON Manager will not configure single board information by ftp mode and is reported to webmaster to be divided into three steps: one, SONManager has found not configure BBU veneer and do not configured RRU, and get relevant not configuration BBU single board information and do not configured RRU single board information; Two, SON Manager will not configure BBU single board information and not configure the form that RRU single board information saves as .xml, sends to corresponding ftp path; Three, webmaster obtains and does not configure BBU single board information and do not configure RRU single board information.
In above-mentioned steps, S402, S404 are that successively executions, S406, S408 are also execution successively, but S402, S404 and S406, S408 can carry out simultaneously, also can successively carry out, and in a word, the relation of the two walks abreast.
