Embodiment
The groundwork process of base station tracing method may further comprise the steps as shown in Figure 3 in the embodiment of the invention:
Step s301, the base station receives activation trace message.
The sign that comprises tracking target in this activation trace message, and the content that need follow the tracks of.Tracking target comprises: the equipment in user, sub-district, interface, the base station, and whole base station in one or more.Wherein, the equipment in the base station comprises: certain DSP (Digital Signal Processing, Digital Signal Processing) chip, CPU, antenna etc.Accordingly, the sign of tracking target comprises: user ID, for example IMSI and IMEI etc.; Cell ID; The interface sequence number; The hardware identifier of the equipment in the base station; Base Station Identification etc.
The base station can be applicable to universal mobile telecommunications system UMTS, LTE (Long Term Evolution, Long Term Evolution Access Network) or HSPA+ (High Speed Package Access plus, high-speed packet inserts and strengthens net).When being applied to UMTS, the base station is NodeB, and it receives activation trace message by Iub interface from RNC; When being applied to code division multiple access access cdma system, the base station is BTS (BaseTransceiver Station), and base station controller is BSC (Base Station Controller), and BTS receives activation trace message from BSC; When being applied to LTE or HSPA+, the base station receives activation trace message from upper layer node (for example core net) or network element webmaster, network webmaster, does not need to communicate by Iub interface.
Step s302, follow the tracks of tracking target according to activation trace message the base station, obtains tracking data.
As previously mentioned, comprise the sign of tracking target in this activation trace message, and need the content of tracking.Such as, the base station knows that according to the sign of tracking target tracking target is subscriber equipment A, and the content of following the tracks of is as required learnt again, needs the up channel power of tracing customer equipment A, and then the up channel power of subscriber equipment A is collected in the base station.Like this, just obtained the keeping track of content that satisfies tracer request.
Step s303, the base station reports network element webmaster or network webmaster with the tracking data that obtains; Indication reports the network element webmaster with the data that will follow the tracks of or the network webmaster is an example in the present embodiment, in fact also can report other and have the network element of following the tracks of processing capacity.
In this step,, can only report the network element webmaster (EM, Element Manager) of this equipment for the keeping track of content that only is applicable to individual equipment; For the keeping track of content that is applicable to whole system, both can report the EM of this equipment, also can report network webmaster (NM:Network Manager).Wherein, the network element webmaster manages individual equipment, the network webmaster manages all devices in the network (comprising individual equipment or network element webmaster), so individual equipment not only can directly report keeping track of content the network webmaster, also can report the network webmaster by the network element webmaster.
In this step, can adopt the different modes that reports.Such as, report in real time or regularly.Wherein real-time report is specially: according to the tracking data that obtains, generate and follow the tracks of report message, give network element webmaster or network webmaster with the tracking report message real-time report of this generation.Regularly report and be specially: according to the tracking data that obtains, generate data file, regularly detect this data file, when this data file size exceeds predetermined threshold value, report network element webmaster or network webmaster.Certainly, also report cycle (can comprise a plurality of sense cycle) can set, if in a report cycle, repeatedly regularly detect the data file size that obtains and all do not exceed predetermined threshold value, then when finishing, this report cycle report this data file to give network element webmaster or network webmaster.
Be understandable that, when the technical scheme that provides when the embodiment of the invention is applied to UMTS, the base station also can report network element webmaster or network webmaster by radio network controller (RNC) with keeping track of content, be specially: the base station obtains after the corresponding keeping track of content, described keeping track of content is sent to RNC, report network element webmaster or network webmaster according to described keeping track of content generation tracking report message or data file by RNC.In addition, in the time of in being applied to cdma system, also keeping track of content can be reported by BSC.
The embodiment of the invention one is an example with the UMTS system, base station tracing method is described, in the present embodiment, tracking to as if user equipment (UE).As shown in Figure 4, this method may further comprise the steps:
Step s401, RNC sends activation trace message by the NBAP signaling method to NodeB.
In the scheme that the embodiment of the invention provides,, activate the tracing task of base station based on signaling method.For example, RNC can utilize existing NBAP signaling (such as public metrical information, special measurement message etc.), and perhaps, by independent signaling RNC Invoke Trace of new establishment, notice NodeB goes to and follows the tracks of Trace.
Wherein, comprise in the RNC Invoke Trace message: comprise the sign of tracking target and the content that needs are followed the tracks of in this message, the sign of tracking target is essential, when for example needing to follow the tracks of certain user's relevant information, this user's IE (Information Element, information element) is the UE sign of tracking target, wherein, because NodeB can't obtain the such UE sign of similar IMSI, IMEI, so the UE sign will adopt CRNC Communication Context ID to identify.Like this, at UE of RNC side sign, NodeB can obtain CRNCCommunication Context ID in the message that RL (Radio Link, Radio Link) sets up, thereby determines it is to follow the tracks of which UE.
The content of tracking target is essential, and the content that needs to follow the tracks of comprises: subscriber equipment, sub-district, interface, non-signaling interface information, non-standard information are followed the tracks of; For example, follow the tracks of for interface message of the user of designated identification etc.
Can also comprise in this RNC Invoke Trace message: track reference IE is used for the trace session of definite appointment uniquely, for optional;
Can also comprise in this RNC Invoke Trace message: follow the tracks of transmission parameter IE (optional), this parameter is used for transmitting trace command to other NodeB, makes it carry out signaling tracing.Wherein, follow the tracks of transmission parameter IE and comprise that the track record content with reference to IE, distributed by CN;
Can also comprise in this RNC Invoke Trace message: tracking depths IE, the level of detail of keeping track of content among the definition RNC is for optional.
Step s402, NodeB read RNC Invoke Trace signaling, carry out the parameter validity checking.
In this step, if parameter validity checking failure, perhaps NodeB does not support RNC InvokeTrace signaling, changes step s403; If parameter is legal, then change step s404.
Step s403 returns RNC INVOKE TRACE FAILURE to RNC.
Step s404, NodeB read the UE sign of RNC Invoke Trace signaling, i.e. CRNCCommunication Context ID.
Step s405 judges whether this corresponding user of UE sign is in state of activation, if step s406 is then changeed in this user's un-activation; If activate, then change step s407.
Step s406 returns RNC INVOKE TRACE FAILURE to RNC.
Step s407, base station initiated NodeB Trace obtains tracking data.
In this step, if comprised tracking depths IE in the RNC Invoke Trace message, then can start NodeB Trace according to the definition of Trace Depth IE, what of keeping track of content tracking depths will determine, as, tracking depths is senior, then can follow the tracks of a large amount of contents, tracking depths is rudimentary, then only needs to follow the tracks of small amounts of content.Be understandable that, the corresponding user's deexcitation of certain CRNC Communication Context ID sign (such as, remove Radio Link) time, if this user Trace function starts, then stop this user Trace function.
Step s408, the base station reports the tracking data that obtains.
As previously mentioned, the mode that reports can have multiple.Such as:
Mode 1: real-time report.NodeB forms and follows the tracks of report message according to the tracking data that obtains.Following the tracks of report message for every is initiatively reported to the network element webmaster (NM) of NodeB in real time by NodeB.
Mode 2: sub conditione reports.
This condition can be: be a threshold value of data file setting.Certainly, also report cycle (can comprise a plurality of sense cycle) can set, if in a report cycle, repeatedly regularly detect the data file size that obtains and all do not exceed predetermined threshold value, then when finishing, this report cycle report this data file to give network element webmaster or network webmaster.
NodeB forms track data file, such as the XML file according to the tracking data that obtains.When data file size surpasses default certain threshold value,, report to the network element webmaster (NM) of NodeB by NodeB by FTP (File Transfer Protocol, file transfer protocol (FTP)) mode.Wherein the NodeB end is as ftp client, and the NM side is made ftp server.Further, in order to reduce to follow the tracks of the FTP transfer of data to the taking of NM and NodeB transmission bandwidth, can be in the NodeB side to track data file earlier through overcompression, upload again afterwards, and, the method for a lot of maturations is arranged about File Compress, as bz2, winzip compression method etc.
Be understandable that the technical scheme that present embodiment provides also may comprise the step of deexcitation:
Step s409, RNC are by the NBAP signaling method, and notice NodeB cancellation is followed the tracks of.
S401 is similar with step, and RNC can utilize existing signaling, perhaps, by independent signaling RNC Deactivate Trace of new establishment, notice NodeB deexcitation.Same, also can comprise UE sign (CRNC Communication Context ID) in this RNC DeactivateTrace signaling, NodeB reads this UE sign, if this corresponding user of UE sign activates, then stop this user's Trace function, if any processing is not then done in this user's un-activation.
In the above scheme, be to do information search, directly send to EM or NM afterwards at NodeB.In addition, can also issue RNC earlier, by the Trace functional entity of RNC tracking data be handled again, send to EM or NM afterwards again by NodeB with the tracking data that obtains form with trace information.
And NodeB can pass through the NBAP means of signaling, sends trace information to RNC.On specific implementation,, comprise and adopt new independent means of signaling and utilize existing NBAP signaling (such as public metrical information, special measurement message) with aforementioned similar.Wherein, adopt new signaling to be specially: to issue a Trace Info of RNC Report message by NodeB.
The technical scheme that adopts the embodiment of the invention to provide can be collected relevant tracked data in the base station, realizes the tracking to base station side information, makes to follow the tracks of more comprehensively effectively.Such as in the UMTS system, can trace into present RNC the information of the NodeB side that can not follow the tracks of.Especially, at HSDPA, HSUPA etc., the managerial ability of NodeB is bigger, can only be just more obvious in the defective that the RNC side is followed the tracks of.Such as, give the NodeB sub-district when RNC only distributes the scope of a sign indicating number resource, by NodeB voluntarily dynamic assignment sign indicating number resource give the user.If when having the user to complain problems such as received signal is bad, such as, may be because user's the poor quality that eats dishes without rice or wine causes the sign indicating number resource of distributing seldom, this can only see at NodeB, can not reflect its reason at the trace information of RNC side.The scheme that present embodiment provides has remedied similar defective, under the bigger scene of NodeB side controlled function, can obtain more comprehensively trace information, thereby can utilize the trace information of acquisition, better realizes fault location, performance test.
And NodeB issues the scheme of EM or NM after the tracking data that obtains is reported, handled by RNC again, the last scheme of comparing, need not at a large amount of tracking datas of NodeB buffer memory, formation XML file and send to EM, NM, and only need send to tracking data RNC timely, allow RNC go the matters of handling preservation, sending, utilize the function of existing RNC tracking entity, further alleviated the burden of NodeB.
Being understandable that, be the example explanation to follow the tracks of UE in the example one in real time, but the present invention is not limited to this, can also follow the tracks of sub-district, interface, non-signaling interface information, non-standard information.Accordingly, the content of tracking can comprise: UE information, cell information, interface message etc.For example: can utilize the special measurement message of NBAP, report more UE information to RNC; Utilize the cell measurement message of NBAP, responding with the sub-district on RNC is cell information of unit etc.Below briefly list when following the tracks of different object the difference of technical scheme.
1, tracing object is UE:
If follow the tracks of at certain or some UE, need relevant UE sign be arranged at NodeB, but NodeB do not have information such as IMSI, IMEI at NodeB.Described in embodiment one, can realize by Communication Context ID at present.Be understandable that, also can assist CCP (Compression Control Protocol, Compression Control Protocol) sign with the UE place.The content of following the tracks of is a UE information.
2, tracing object is the sub-district:
If follow the tracks of at certain or some sub-districts, then should be with sub-district ID sign at NodeB.In addition, can also carry the information of following the tracks of the sub-district, count such as community user number and CE (Channel Element, Channel Elements).Can obtain the situation that CE consumes by following the tracks of, such as up CE always count, descending CE always counts, up CE counts consumption, descending CE counts consumption, this cell uplink CE counts consumes and this cell downlink CE data such as consumption of counting, and is congested to judge whether the user.
3, tracing object is an interface:
If at NodeB at Iub, Iuant, or the tracking of interface message between Iutma signaling, base station baseband plate unit (BBU) and the Remote Radio Unit (RRU) then can be with corresponding information, similar CN Invoke Trace message in activating message.For example, may include IE type as shown in table 1 and parameter field among the RNC Invoke Trace: which interface is used for the explanation tracking is.Wherein, Iuant is the interface of NodeB to antenna, and Iutma is the interface of NodeB to tower amplifier (TMA).
Table 1:
| IE/ organizes Name | Presence | Scope | IE type and parameter | Syntactic description |
| Follow the tracks of interface list | ||||
| Follow the tracks of interface | 1to <maxInterf aces> | |||
| Interface | M | Enumerate (Iub, Iuant, Iutma...) |
4, tracing object is non-signaling interface information:
Because the cause that realizes, at present Trace at be the signaling information of some standard interfaces, and do not have network element internal information.But in fact, a lot of information have nothing to do with realizing, such as the information of NodeB at HSDPA user, and the CQI of reporting of user (channel quality indicator, channel quality indication) information, the statistics of the Ack/Nack number of user feedback.As previously mentioned, give the NodeB sub-district when RNC only distributes the scope of a sign indicating number resource, by NodeB voluntarily dynamic assignment sign indicating number resource give the user.If when having HSDPA user to complain problems such as received signal is bad, such as, may be because user's the poor quality that eats dishes without rice or wine causes the sign indicating number resource of distributing seldom, this can only see at NodeB, but at present in Iub interface, reflecting.So, can follow the tracks of non-signaling interface information.
Concrete, the Trace information of NodeB can further include following information:
For example, for the interface between RNC and the NodeB, have by following the tracks of the information that to obtain: the discontinuous FP bag sum that FP bag sum, the NodeB that NodeB receives receives, the FP bag sum that NodeB abandons and physical link (E11/STM-1) error rate etc., by above information, can judge whether Iub interface is normal.
Trace information for the sub-district can further include: there is HSDPA user's time scale the sub-district, there is the time scale of HSDPA user data the sub-district, sub-district HS_SCCH sign indicating number utilance, sub-district HS_PDSCH sign indicating number utilance, sub-district HSDPA MAC-hs average throughput, sub-district HSDPA average power, the overtime data loss ratio of sub-district HSDPA, sub-district Iub bandwidth utilization rate, current HSDPA in sub-district or HSUPA number of users, field type user HSDPA information, length of field etc., and HSDPA user's Mean Speed, this user CQI is in 0～5 number of times, this user CQI is in 6～10 number of times, this user CQI is in 11～15 number of times, this user CQI is in＞16 number of times, HSDPA user's average CQI, total number of HSDPA user's ACK; Total number of HSDPA user's NCK.
5, the object criteria of right and wrong information of Gen Zonging:
