Description
Technical field
The present invention relates to the signaling tracing field in the wireless communication technology, particularly a kind of signaling tracking method and system.
Background technology
Signaling tracing is the effective means of carrying out data record and debugging that mobile communcations system provides.When radio network controller (RNC) need carry out signaling tracing to subscriber equipment (UE), can be based on IMSI International Mobile Subscriber Identity (IMSI) and Temporary Mobile Subscriber Identity (TMSI), or can carry out signaling tracing based on IMSI and packet domain temporary mobile subscriber sign (P-TMSI).Wherein, IMSI is stored in User Recognition (SIM) card, no matter how the position of UE changes, IMSI can not change; TMSI and P-TMSI are identified by the casual user of core net (CN) dynamic assignment for the confidentiality of strengthening system, and for the fail safe that guarantees that the mobile subscriber discerns, CN can periodically update the TMSI/P-TMSI of UE.So in the process of signaling tracing, know and the corresponding relation that maintains IMSI and TMSI/P-TMSI seems particularly important.
In the prior art, signal following system is made up of LMT Local Maintenance Terminal/operation maintenance center (LMT/OMC), RNC and CN.Fig. 1 shows the message flow chart of existing startup signaling tracing.As shown in Figure 1, the message flow of startup signaling tracing may further comprise the steps:
Step 101, LMT/OMC sends signaling tracing to RNC and starts (START, IMSI TraceRequest) message, and this message is carried the IMSI of the UE that is followed the tracks of.
Step 102, RNC receives the signaling tracing initiation message of carrying IMSI information, returns signaling tracing to LMT/OMC and starts response (START, IMSI Trace Response) message.
Step 103, RNC sends request TMSI/P-TMSI (TMSI/P-TMSI StartRequest) message to CN, asks the TMSI corresponding with IMSI.
Step 104 after CN receives TMSI/P-TMSI Start Request message, is inquired about the TMSI/P-TMSI corresponding with this IMSI, and carries TMSI/P-TMSI in request TMSI/P-TMSI response (TMSI/P-TMSI StartResponse) message.
Fig. 2 shows the existing message flow chart that stops signaling tracing.As shown in Figure 2, the message flow that stops signaling tracing may further comprise the steps:
Step 201, LMT/OMC transmission signaling tracing stops (STOP, IMSI Trace Request), and message is to RNC, and this message is carried the IMSI of the UE that need stop signaling tracing.
Step 202, after RNC received that the signaling tracing that comprises IMSI stops message, RNC deleted the task that this IMSI follows the tracks of, and returned signaling tracing to LMT/OMC and stopped response (STOP, IMSI TraceResponse) message.
Step 203, RNC sends to CN and stops TMSI/P-TMSI request (TMSI/P-TMSI StopRequest) message, and announcement CN no longer needs to upgrade the corresponding relation of TMSI/P-TMSI and IMSI.
Fig. 3 shows the message flow chart of existing renewal TMSI/P-TMSI.As shown in Figure 3, the message flow of renewal TMSI/P-TMSI may further comprise the steps:
Step 301, when distributing to other users as the TMSI/P-TMSI of CN change appointment UE or the TMSI/P-TMSI of UE, CN sends TMSI/P-TMSI to RNC and upgrades (TMSI/P-TMSIUpdate Indication) message, after RNC receives the TMSI/P-TMSI updating message, upgrade the corresponding relation of TMSI/P-TMSI and IMSI.
In existing signaling tracking method, signaling tracing relies on the startup flow process of signaling tracing, these three flow processs of the more new technological process that stops flow process and TMSI/P-TMSI of signaling tracing to realize.By the startup flow process of signaling tracing, RNC obtains the pairing TMSI/P-TMSI of IMSI of the UE that needs tracking for the first time; The more new technological process of TMSI/P-TMSI can make RNC obtain the IMSI of UE and the corresponding relation of TMSI/P-TMSI in real time; When not needing this UE followed the tracks of, can realize by the flow process that stops of signaling tracing.But these three flow processs all must rely on the Signalling exchange of RNC and CN to finish, for example, in the startup flow process of signaling tracing, TMSI/P-TMSI Start Request and TMSI/P-TMSI Start Response message have been introduced between RNC and the CN, in the more new technological process of signaling tracing, introduced TMSI/P-TMSI Update Indication message between RNC and the CN, stopping in the flow process of signaling tracing, introduced TMSI/P-TMSI StopRequest message between RNC and the CN, as seen, existing signaling tracking method is owing to repeatedly introduced message between RNC and CN, therefore signaling tracing has been subjected to the restriction of CN, and is subjected to being responsible for the restriction of the Iu agreement on the Iu interface of Signalling exchange between CN and the RNC.So only have for example RNC and do not have the manufacturer of CN just need to cooperate of access device, complicated operation, cost height with other manufacturers.

Embodiment
For making purpose of the present invention, technical scheme and advantage clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, the present invention is described in more detail.
Fig. 4 is the structure chart of a kind of signal following system provided by the present invention, and as shown in Figure 4, this signal following system comprises: UE401, RNC402, be used to obtain the tracking control unit 403 with the sign of configuration UE.In tracing process, tracking control unit 403 is resolved public identifier that comes from CN and the non-access layer information that RNC402 transmitted, the IMSI of the UE401 that is followed the tracks of to obtain and the corresponding relation of TMSI/P-TMSI, the parameter configuration that will comprise this corresponding relation is again given the RNC402 that is used to follow the tracks of UE, and RNC402 follows the tracks of UE401 according to the parameter that is disposed.
Wherein, described RNC402 comprises at least: message judge module 4021, tracking module 4022, message transmitting module 4023, Configuration Manager 4024; Described tracking control unit 403 comprises: first configuration module 4031, message sink module 4032, tracking data parsing module 4033, second configuration module 4034.
Before following the tracks of beginning, the sign of first configuration module, 4031 configuration UE 401, and the sign that is disposed sent to message judge module 4021, simultaneously, the RRC that UE401 will carry its sign connects and sets up request message and send to message judge module 4021; Message judge module 4021 judges sign that first configuration module 4031 disposed and RRC connect whether set up the entrained sign of request message consistent, if unanimity then notifies tracking module 4022 to start tracking to UE401 immediately; Otherwise judge module 4021 is judged sign that first configuration module 4031 disposed with whether consistent from the entrained sign of the public identifier of CN and non-access layer information, if consistent, then notifies tracking module 4022 to start tracking to UE401 immediately; Otherwise, finish to follow the tracks of.
In tracing process, tracking module 4022 receives the public identifier that comes from CN and non-access layer information and this message is transmitted to message sink module 4032 via message transmitting module 4023, tracking data parsing module 4033 receives the public identifier that comes from CN and non-access layer information via message sink module 4032 and this message is resolved, the IMSI of the UE401 that is followed the tracks of to obtain and the corresponding relation of TMSI/P-TMSI, the parameter configuration that second configuration module 4034 receives the corresponding relation of the IMSI of the UE401 that comes from tracking data parsing module 4033 and TMSI/P-TMSI and will comprise this corresponding relation is given and is used for the Configuration Manager 4024 that leading subscriber is followed the tracks of configuration information, tracking module 4022 according to the corresponding relation of IMSI in the Configuration Manager 4024 and TMSI/P-TMSI to realize the tracking of RNC402 to UE401.Described configuration is specially: the parameter that second configuration module will comprise the corresponding relation of the IMSI of UE401 and TMSI/P-TMSI sends to Configuration Manager 4024, and this information interactive process is realized by Simple Network Management Protocol (SNMP).In actual applications, RNC402 and tracking control unit 403 are connected by Ethernet interface, and adopt SNMP to realize the mutual of information.
Based on above-mentioned signal following system, Fig. 5 is the flow chart of a kind of signaling tracking method provided by the present invention, and as shown in Figure 5, this signaling tracking method may further comprise the steps:
The UE of tracking control unit configuration is designated IMSI or TMSI or P-TMSI, or disposes IMSI and TMSI simultaneously, or disposes IMSI and P-TMSI simultaneously.TMSI and P-TMSI are Temporary Mobile Subscriber Identity, when CN is the CN of circuit commutative field (CS territory), the Temporary Mobile Subscriber Identity of the UE that tracking control unit disposed is TMSI, when CN was the CN of packet-switched domain (PS territory), the Temporary Mobile Subscriber Identity of the UE that tracking control unit disposed was P-TMSI.TMSI and P-TMSI are all unique corresponding with the IMSI of UE.
Step 502, UE sends Radio Resource control (RRC) connection to RNC and sets up request message, and this message comprises the sign of UE.
The sign that RRC that UE sent connects the UE that sets up in the request message to be comprised can be TMSI or P-TMSI or IMSI.
RNC in tracing process, CN to the Common of its transmission ID﹠amp; The NAS forwards is given tracking control unit, and tracking control unit obtains the IMSI of UE and the corresponding relation of TMSI/P-TMSI by resolving this message.If the UE that tracking control unit disposed in step 501 is designated IMSI, then in step 505, tracking control unit is by resolving Common ID﹠amp; NAS message is obtained TMSI or the P-IMSI of UE; If the UE that tracking control unit disposed in step 501 is designated TMSI or P-IMSI, then in step 505, tracking control unit is by resolving Common ID﹠amp; NAS message is obtained the IMSI of UE.
Tracking control unit will comprise obtained the IMSI of UE and the parameter configuration of the corresponding relation of TMSI/P-TMSI give RNC, and dispose other parameters simultaneously, for example: need the interface followed the tracks of, the time span of tracking.
When RNC has obtained the TMSI of UE and the corresponding relation of IMSI for the first time, or behind the corresponding relation of P-TMSI and IMSI, if after this CN has upgraded TMSI or the P-TMSI of UE, CN can pass through Common ID﹠amp; NAS message is informed RNC, and RNC is with Common ID﹠amp; The NAS forwards is given tracking control unit, tracking control unit is resolved after this message the new IMSI of UE and the corresponding relation of TMSI or the corresponding relation of IMSI and P-TMSI is reconfigured to RNC, RNC always can be known the IMSI of UE and the corresponding relation of TMSI/P-TMSI in real time like this, guarantees the accuracy and the continuity of following the tracks of.In ensuing process, no matter UE starts RRC with TMSI or P-TMSI or IMSI and connects the request of foundation, and UE can be by real-time tracking.
Above-mentioned steps 501-506 is a complete signaling tracing process.
The IMSI that is designated as the UE of tracking control unit in step 501 configuration, and UE starts RRC connection foundation request by TMSI or P-TMSI, RNC judge the sign of the UE of tracking control unit configuration is connected with RRC foundation ask in the sign of UE inconsistent, then RNC does not carry out the tracking of UE immediately, up to the Common ID﹠amp that receives that CN sends; After the NAS message, when RNC judges CommonID﹠amp; When the IMSI that carries in the NAS message is consistent with the IMSI of tracked UE, ability execution in step 504; Otherwise, execution in step 508.
It is pointed out that in existing mobile communications system,, illustrate that this TMSI or this P-TMSI have been assigned to certain UE if tracking control unit can dispose TMSI or P-TMSI to UE.When UE not only had been assigned with TMSI or P-TMSI but also had been assigned with IMSI, UE can at first use TMSI or P-TMSI to set up signaling procedure and can at first not use IMSI to set up signaling procedure.
For switching the user who goes into RNC, RNC is after receiving the request of redistributing (Relocation Request) message that CN sends, when RNC judges that the IMSI that carries in the Relocation Request message is consistent with the IMSI of tracked UE, ability execution in step 504; Otherwise, execution in step 508.
Step 508 finishes to follow the tracks of.
Under normal circumstances, Common ID﹠amp; IMSI in the NAS message is consistent with the IMSI of tracked UE, but under some abnormal conditions, Common ID﹠amp; IMSI in the NAS message and the IMSI of tracked UE are inconsistent.Under this abnormal conditions, then RNC stops to follow the tracks of, and Common ID﹠amp; NAS message sends to tracking control unit, and it is unusual that tracking control unit detects IMSI, and then tracking control unit stops the storage to current signaling tracing related data, in order to avoid RNC continues the user of trail-and-error.
Above-mentioned steps 501,502,503,507,504,505,506 also is a complete signaling tracing process.
This shows, signal following system provided by the present invention and method adopt tracking control unit to resolve public identifier that comes from CN and non-access layer information that RNC transmitted, the IMSI of the UE that is followed the tracks of to obtain and the corresponding relation of TMSI/P-TMSI, tracking control unit will comprise the parameter configuration of this corresponding relation again and give RNC, make RNC carry out real-time tracking to UE.And in the prior art, also exist CN to send the step of public identifier and non-access layer information to RNC, only RNC directly sends to UE with public identifier and the non-access layer information that CN sent, the maximum characteristics of this bright technical scheme that provides are, RNC has given tracking control unit with this forwards, finish the parsing of the corresponding relation of the IMSI of UE and TMSI/P-TMSI by tracking control unit, so just avoided between RNC and CN, repeatedly producing new Signalling exchange, avoided signaling tracing to be subjected to CN, the restriction of the Iu interface between RNC and the CN, in addition, in the prior art, the mutual employing Iu agreement between RNC and the CN.The protocol stack structure relative complex, and in signal following system provided by the present invention and method, mutual employing Simple Network Management Protocol (SNMP) between RNC and the tracking control unit, general network element device for example RNC all provides Ethernet interface, can be connected with tracking control unit easily.
