Description
Technical field
The present invention relates to the tracing management in the communication network.Especially, the present invention relates to concentrate tracing management at the automation of the activation of the local trace in the network.
Background technology
Following the tracks of notion is known in the field of network management and particularly communication network management.For this reason, in network, set up the trace file that is used for each tracked object, this network can for example be a second generation network, as GSM (global system for mobile communications), perhaps third generation network, as UMTS (Universal Mobile Telecommunications System) or CDMA (code division multiple access), perhaps any go-between such as GPRS (GPRS).
With tracked object can be subscriber or equipment.Therefore, generally distinguish the subscriber and follow the tracks of (promptly following the tracks of for example subscriber's IMSI International Mobile Subscriber Identity IMSI) and equipment tracking (promptly following the tracks of for example International Mobile Station Equipment Identification IMEI or International Mobile Station Equipment Identification software version number IMEISV).The tracking type classification that another generally uses comprises seeervice level tracking and Service tracing.
Tracking is suitable for call level (call level) specifying information that provides relevant with one or more tracked concrete object.Follow the tracks of so that the ability of charging to the data on any interface at concrete object at call level allow to obtain the information that for example can not obtain from performance measurement.The data of collecting by tracking can be used for monitoring or optimizing purpose like this.
For each tracking, all activation trace sessions, this trace session is such time interval, during this time interval, can carry out the track record session of this specific tracking so that collect track record information.Generally speaking, from also being referred to as network management (NM) side (promptly on the notional downward direction) activation trace of operation support system (OSS) side.Follow the tracks of to activate that the tracking that can be based on management activates or activate based on the tracking of signaling, these two is known to those skilled in the art.Carry out subscriber's tracking and equipment being subordinate in network in network element or the NE Explorer and follow the tracks of (perhaps seeervice level is followed the tracks of and Service tracing).The data (being track record) of collecting are sent to notional upper network layer then, as network management (NM) layer or operation support system (OSS) layer, to assess.In this upper strata, manage tracking and track record thereof existing and plan.
In " 3GPP TS 32.421 v7.0.0 " in September, 2005, in the notion of defined tracking framework and the requirement, distinguish two kinds of different basically telecommunication management frameworks and realized, be referred to as system environments (system context) A and system environments B.In so-called system environments A, related management interface Itf-N is between network manager and NE Explorer, and this NE Explorer is between the conceptive network element that is arranged in network manager and carry out follows the tracks of and managed by NE Explorer.In so-called system environments B, related management interface Itf-N is between network manager and network element that carry out to follow the tracks of, and wherein network element is embedded into its NE Explorer among himself.
In " 3GPP TS 32.422 v6.5.0 " in December, 2005 the 7th to 24 page, set forth and trace session activation more details relevant with deexcitation from the viewpoint of tracking Control and configuration management, at this it is carried out reference.
According to prior art, known this network management side is also managed the tracking that has activated and will be activated generally from the tracking of network management side activating, and also receives the record of the tracking that has activated.Therefore, following the tracks of configuration data is consistent in the network management side.
Be not used in from any other device except network management and come the standardized way of activation trace session effectively, although this is desirable.Yet this local activation of following the tracks of in network can cause some problems.Such problem is all relevant with load control item with management issue.
With regard to management issue, these problems are relevant with the consistent and effective tracing management.That is, when will be when the network management remote activation is followed the tracks of, the track record of collection will still must be sent to network management.Therefore, network management will receive the track record of the tracking that is not activated by management system as yet and therefore also do not have to register in management system.Thereby no longer can realize effective tracking Control.In addition, will be difficult to manage and locate tracking and the related information of being abandoned from several network elements, this will be essential for the roaming of system-level scope and/or tracked subscriber/equipment.
With regard to load control item, the load on network management or the operation support system may become too high and possibility is oppositely controlled.Load and the load on any management interface in carrying out the network element of following the tracks of also may become too high.
More eventful relevant with these problems is that trace information is responsive, and follows the tracks of and use the strict control that is subjected to law at particular country.
Thereby, also be not used in the known solution of handling and managing not the tracking that is activated by network management effectively.Therefore, need a kind of mode, with the solution that is used to provide such at the problems referred to above and deficiency.

Embodiment
Here with reference to specific non-restrictive example the present invention is described.Those skilled in the art will recognize that to the invention is not restricted to these examples, but can be applied more widely.
Particularly, in conjunction with the telecommunications management network (tmn) term the present invention is described.Such term only uses in the environment of presenting example, rather than limits the present invention by any way.
Fig. 1 shows the flow chart of method according to an embodiment of the invention.This method relates to a kind of communication network, this communication network be included in the network management entity that hereinafter is referred to as network manager NM with depend on relevant particular system environment be referred to as NE Explorer or network element hereinafter at least one be subordinate to network entity.
In Fig. 1, the above the first half of dotted line relates to the above-mentioned method of operation that is subordinate to network entity in the method flow, and the following the latter half of dotted line relates to the method for operation of above-mentioned network management entity in the method flow.
Method according to Fig. 1 relates to the situation that network entity generally is authorized to the local activation trace session.Therefore need not to authorize in the network management entity checking.
In the step S1 of Fig. 1, be subordinate to network entity place local activation trace session (perhaps changing the parameter of trace session) in this locality.That is to say that this entity (being network element or NE Explorer) need not network manager or any other device asks and start session activation voluntarily or change to have trace session now.Can for example come local such local activation that triggers at this entity place or via the remote interface that leads to this entity.
When activation trace, according to a preferred steps in the method for present embodiment be: being subordinate to the definite trace session that has activated in network entity place is (the step S2) that is started by network management entity or be subordinate to network entity startup itself.This step is used for making the notification overhead of network to minimize.
Activate by being subordinate to network entity itself (being NE Explorer EM or network element NE) if determine session in step S2, then this flow process continues step S3.Then, will indicate the notice of having created trace session to send to network management entity.Decide on relevant system environments, can or utilize intermediate entities to transmit the transmission (referring to Fig. 4 to Fig. 6) that notice is come exercise notice with direct mode.
Under any circumstance, notice can comprise one or more in the following parameter: being subordinate to the network entity identifier, following the tracks of excited users name, tracking target identifier, unique trace session identifier and/or trace session activation time of the network entity of activation trace session.Under the situation that the subscriber follows the tracks of, the tracking target identifier comprises the subscriber identifier with tracked subscriber.Under the situation of IP Multimedia System (IMS), subscriber identifier for example is a public user identity.Under the situation that equipment is followed the tracks of, the tracking target identifier comprises the device identifier with tracked equipment.Under the Service tracing situation that also is referred to as " many MS follow the tracks of ", the tracking target identifier comprises the destination object with tracked business.Under the situation that seeervice level is followed the tracks of, the tracking target identifier comprises service identifiers.
Under situation about activating based on the tracking of signaling (and especially but and not exclusively, be NE Explorer if be subordinate to network entity), notice also comprises the tabulation of the network entity or the network element of activation trace session alternatively.This tabulation also can comprise the type separately of network entity or network element.
In the above-mentioned parameter one or more may be essential for notice, as for example network entity identifier, trace session identifier and tracking target identifier.
After sending notice, determine in step S2 that perhaps under the initial situation by network manager NM startup of session, this flow process continues the actual tracking operation among the step S4.In any case why this sets up is because this network entity always is authorized to the activation trace session as mentioned above.Such tracking operation is owing to will here not described with the present invention who pays special attention to tracking activation and management is irrelevant.
In step S5, in the network management entity side, receive from being subordinate to the notice that network entity sends, in step S6, check this notice immediately.In step S6,, and, check the trace session that has activated according to preassigned of for example in the local data base of network management entity, storing and existing trace session by the parameter that in corresponding notice, comprises.The check result of step S6 has been specified the operation species of carrying out among the follow-up management step S7 (this uses from step S7 and represents to the dotted arrow of step S4) in Fig. 1, in the follow-up management step, sentence centralized system management trace session in network management entity.On the standard that is used to check step (for example the load on the network management entity, be subordinate to load on the network entity, the deexcitation of centralized network level, safety event and according to the permission that can permit the trace session tabulation) decide, management process can comprise: the automatic configuration of for example described trace session that has activated (being the modification of tracking parameter), the automatic deexcitation of the perhaps current trace session that has activated, perhaps same trace session is in the automatic activation (being duplicating of trace session) at one or more other network entity place.For this reason, network management entity according to the present invention is configured to send in the network one or more in order to reconfiguring of will being scheduled to/deexcitation/activation message and is subordinate to network entity.
For example, if detecting its load, network management entity increases, thereby perhaps make current identifier not unique, so the current trace session of network management entity deexcitation immediately because of being used and having distributed to another trace session that has existed by network management entity such as the such sign of trace session identifier.Trace session is copied to " neighbours " network element or the NE Explorer of the network entity that activates current trace session, and this has for example realized more complete switching tracking routine.Can utilize the tracking excited users name parameter in the notice and abuse the situation of system and it is made a response so that detect certain user.
According to alternative an enforcement of the present invention, network management entity is not carried out inspection step S6 but is proceeded directly to management process S7 when notified.Under these circumstances, bookkeeping is based on predetermined action and need not to consider any one above-mentioned standard.
In fact, method of the present invention is based on trace session and is subordinate to the local activation at network entity place at least one, and the notice of the described trace session that has activated is subordinate to the transmission of network entity to network management entity from least one.
Fig. 2 shows the flow chart of method according to another embodiment of the present invention.Because this method is similar to the method for Fig. 1, so hereinafter only describe difference.Can be about more details with reference to description in conjunction with Fig. 1.
Compare with the basic situation among Fig. 1, under this situation, the common uncommitted local activation trace session of network entity.In fact network entity starts trace session activation, is ready to be at this moment the final activation of pending status immediately, and waits for the affirmation from network management entity.Therefore must authorize in the checking of network management entity place.
Therefore, will be understood that to start the session activation that to confirm in addition by network management entity according to the step S1 of the method for Fig. 2.When notified, network management entity is verified the permission (step S6) that to the mandate of the trace session that has activated, promptly network entity is activated this trace session.
If the checking result in step S6 is sure ("Yes" among Fig. 2), then this flow process proceeds to the step S7 that is used to manage trace session.The step S7 of Fig. 2 corresponds essentially to the step S7 of Fig. 1.Though not shown in Fig. 2, in this example embodiment, also can carry out inspection step alternatively, promptly between verification step S6 and management process S7 according to the step S6 of Fig. 1.Therefore, to the management of the trace session that activated can be only based on the checking result or based on the combination of checking result and check result.
The trace session management of step S7 proceeds to and sends the acknowledgment to network entity (step S8).In this affirmation, carry about activation, deexcitation and/or the details that reconfigures.Receive and analyze this affirmation (step S9 and S10) at network entity then.According to the analysis result of step S10, finally activate the unsettled tracking operation of step S4.
If the checking result in step S6 is ("No" among Fig. 2) of negating, then this flow process continues step S11, wherein abandons trace session at the network management entity place immediately and starts.Alternately, Negative Acknowledgement can be sent to the network entity (not shown in FIG.).
Fig. 3 shows the flow chart according to the method for further embodiment of this invention.Because this method is similar to the method for Fig. 1, so difference hereinafter only is described.Can be about more details with reference to description in conjunction with Fig. 1.
Compare with the basic situation of Fig. 1, in this situation, the common uncommitted local activation trace session of network entity.Network entity but trigger trace session activation.That is, the trace session activation at the network entity place will be understood that " suggestion " to the activation trace session.The notice (referring to step S3) that has this suggestion in transmission afterwards, network entity is compared the record that does not keep this trace session with the situation of Fig. 2, promptly network entity is abandoned the understanding to following the tracks of.Therefore, after the step S1 of Fig. 3, network entity is not in ready or pending status, but the corresponding trace session activation of trigger network management entity order.Yet, must verify the mandate that triggers trace session for this locality once more at the network management entity place.
As implied above, will be understood that therefore that according to the step S1 of the method for Fig. 3 triggering session activates, this session activation must come order by network management entity subsequently.When notified, network management entity is verified the permission (step S6) that to the mandate of the trace session that has activated, promptly network entity is activated this trace session.
If the checking result in step S6 is sure ("Yes" among Fig. 3), then this flow process proceeds to the step S7 that is used to manage trace session.The step S7 of Fig. 3 corresponds essentially to the step S7 of Fig. 1.Though not shown in Fig. 3, in this embodiment, also can carry out inspection step alternatively, promptly between verification step S6 and management process S7 according to the step S6 of Fig. 1.Therefore, to the management of the trace session that activated can be only based on the checking result or based on the combination of checking result and check result.
Compare with Fig. 2, the trace session management of step S7 does not have directly to activate the tracking operation of step S4.But order is to the activation of trace session, in view of the above network entity once more execution in step S1, promptly " activate " tracking again.Thus, the logic activation of step S1 logically stems from network management entity rather than network entity.Therefore, this flow process proceeds to step S2 to step S4, begins actual tracking at step S4.
If the checking result in step S6 is ("No" among Fig. 3) of negating, then this flow process continues step S8, wherein abandons trace session activation immediately at the network management entity place.
Fig. 4 shows in system environments A the schematic block diagram of management system for tracking according to an embodiment of the invention.
According to the present invention, the system of Fig. 4 comprises the network management entity that is designated as NM (network manager) and is designated as EM (being used for NE Explorer) and two of NE (being used for network element) are subordinate to network entity.NE Explorer EM makes network element NE and network manager NM interface communication.Note, for the sake of brevity, only show a network element and NE Explorer respectively by example.
The network element of Fig. 4 can be operated according to the method in the top of Fig. 1.For this reason, it comprises active device and dispensing device, this active device is used for local activation trace session (at least one user equipment (UE)), it further comprises the user interface (not shown in FIG.), and this dispensing device is used for the notice of the described trace session that has activated is sent to network management entity NM.Provide (therefore in frame of broken lines, illustrating) to determine device alternatively, be used for determining that the described trace session that has activated is to be started or network element NE startup by network manager NM.Under this situation of system environments A, determine that the trace session that has activated is started by network manager NM if determine device, then dispensing device is operable as and does not send notice.Otherwise, such notice (having above-mentioned parameter) is sent to network manager NM, right rather than with direct mode.Dispensing device but can operate in order to notice is sent to its intermediate NE manager, wherein NE Explorer EM comprises the retransmission unit that is used for notice is forwarded to network manager NM.
The network manager of Fig. 4 is just operated according to the method in the latter half of Fig. 1.For this reason, this network manager comprises: receiving system is used to receive the notice of the trace session that has activated; Optional authentication and/or testing fixture, be used for receiving that described when notice checking verifies and/or check the trace session that has activated to the mandate of the trace session that activated, and management devices, if be used for regard to checking and/or result that testing fixture obtained suitable, the trace session that has activated in the centralized management of described network manager place then.Checking/testing fixture can be operated according to the step S6 of Fig. 1, Fig. 2 and Fig. 3, wherein realizes checking and/or audit function by local data base DB.Management devices can be operated according to the step S7 of Fig. 1, Fig. 2 and Fig. 3.
