Embodiment
The invention provides a kind of user signaling tracking method and communication system and subscriber equipment, be used to improve the performance of signaling tracing.
At following Long Term Evolution (LTE, Long Term Evolution) mobile communication system or universal mobile telecommunications system (UMTS, Universal Mobile Telecommunications System) lining, Non-Access Stratum (NAS between UE and the core net node, Non Access Stratum) message is very frequent, be connected with the initial of network such as UE, the position is upgraded, service request etc., the parameter of utilizing these interactive information directly to pass on core net node or EMS to follow the tracks of, and reside at UE, when then in case UE is connected with access network node generation signaling, resident tracking parameter can bring access network node the very first time, and impel access network node at once all signaling messages of UE to be followed the tracks of, even if access network node does not also obtain detailed tracking parameter like this, also realize early stage tracking, can improve the efficient of user signaling tracking.
The scheme that the following embodiment of the invention is described both can be used for LTE, also can be used for UMTS, can also be used for other communication systems such as Wimax network, correspondingly:
In LTE, access network node is evolution base station (eNB, evolved Node B), and core net node is mobile management entity/user entity (MME/UPE, Mobility Management Entity/UserPlane Entity);
In UMTS, access network node is RNC (a Radio Network Controler radio network controller), core net node is service universal grouping wireless serving GPRS support node/mobile switching centre (SGSN/MSC, Serving GPRS Support Node/Mobile Switching Center);
In Wimax, access network node is base station (BS, Base station), and core net node is gateway (GW, Gate Way).
In gsm system, access network node is BSC, and core net node is MSC.
And subscriber equipment or mobile subscriber can be in the above system travelling carriage (MS, MobileStation), subscriber equipment (UE, User Equipment) etc.
Access network node of mentioning in the narration of back or core net node can be according to the different entities of selecting correspondence of the network of practical application.
Below user signaling tracking method in the embodiment of the invention is described in detail:
See also Fig. 1, user signaling tracking method comprises in the embodiment of the invention:
101, UE obtains and follows the tracks of sign;
UE obtains from core net node and follows the tracks of sign, and concrete obtain manner will be described in detail in the back.
Tracking is designated certain parameter in the tracking parameter, can be Trace Identifier (Trace Flag), can also be in the tracking parameter other can the unique identification tracking parameter and UE between the parameter of corresponding relation, be that example describes with the Trace Identifier in the present embodiment:
There are several selections the position of Trace Identifier Trace Flag in message:
1) the Option item in the message format: form by IE Tag+Trace Flag.Such as, when in message, occurring, represent this UE to need to follow the tracks of, when not occurring, then representative is not followed the tracks of or the cancellation tracking;
2) fixterm in the message format: only the 1bit Flag by the fixed position forms.Such as, this position 1 representative needs to follow the tracks of, and this position 0 representative does not follow the tracks of or cancellation is followed the tracks of.
Because Trace Identifier is set only takies a bit, thus all very little to the requirement of system resource, UE and system-computed ability, being simple and easy to usefulness, realizability is strong.
102, send article one message that comprises the tracking sign;
When business was carried out in user's request, UE sent article one message to the access network node of correspondence, comprised described tracking sign in described article one message.
Article one, message can be Radio Resource control (RRC, Radio Resource Control) message, or NAS message, or RRC/NAS merges message.
103, carry out signaling tracing according to following the tracks of sign.
After access network node receives described article one message, the signaling of described subscriber equipment is followed the tracks of according to tracking sign wherein.
More than described UE obtain follow the tracks of sign after, access network node can utilize this trackings sign to finish the signaling tracing of this UE, what UE got access in the above method can be not only to follow the tracks of to identify, and also can be other tracking parameters.
Below UE in the embodiment of the invention being obtained the tracking label manner is described in detail, be that core net node passes through NAS message to UE transmission tracking sign on the whole, carry in this NAS message and follow the tracks of sign, concrete for following three examples, be understandable that, can also be other NAS message equally, flow process be similar substantially:
One, issues tracking parameter in the attachment flow;
When UE attempted being connected with network (start shooting, reset or unusually then reconnect), UE will at first initiate attachment flow and core net node adheres to.
After UE Attach Request message (attach request) is sent to core net node, core net node generally will with home subscriber server (HSS, Home Subscriber Server) takes place alternately, extract information of some relevant these UE in the HSS, these information generally are used for the label power of UE and authentication etc.With the mutual process of HSS in, if the information that will follow the tracks of this UE is arranged in the HSS, then HSS will pass to core net node to these parameters of the tracing command, be understandable that, the tracking parameter that obtains certain UE on the core node normally obtains from HSS, and the tracking parameter on the HSS is provided with by EMS.Yet the embodiment of the invention is not got rid of core net node and is obtained tracking parameter by other modes, and for example direct EMS by core net node is provided with acquisition etc.In addition, the trace labelling that passes to UE also may not need EMS to be provided with, and by the actual needs that the management system basis of core net node is followed the tracks of this UE, directly adds this message elements in structure attach accept message.
See also Fig. 2, attachment flow issues the tracking parameter flow process and comprises in the embodiment of the invention:
201, UE search SAE/LTE connecting system is carried out connecting system and network selecting.If exist network to share, can select other shared network;
202, UE sends an attach request message to MME/UPE, comprises the UE sign in the message.If adopt network to share, attach request also may comprise the information of selecting network or MME/UPE.Attach request can comprise the information of default IP access bearer;
203, user and UE carry out authentication in MME/UPE;
204, MME/UPE registers in HSS and will serve this UE;
205, HSS confirms the registration of MME/UPE.The subscription information of not only default IP access bearer information is transmitted, and also will will authorize the strategy and the charging control information of default IP access bearer to pass to MME/UPE;
206, other is about the basic connection setting of anchor gateway, route and IP carrying QoS;
207, MME/UPE accepts the network connection of UE, distributes to temporary mark of UE, and passes to the IP address of its appointment.Also will check roaming information simultaneously, if violate the roaming restriction, network connects and will be rejected.This programme has increased corresponding tracking parameter in Attach Accept message, can be used as NAS message and bring UE equipment;
208, UE confirms network successful connection, return messages.So far UE is attached to the operation success of LTE core net.
In the present embodiment, the tracking parameter that MME/UPE feeds back to UE can only carry a tracking sign, can save the channel resource of eating dishes without rice or wine like this, has improved network resource utilization.
Two, the position more issues tracking parameter in the new technological process:
Utilize the position more new technological process bring UE trace labelling, can when UE moves out present Tracking Area zone, notify up-to-date trace command to UE and access network node.
See also Fig. 3, embodiment of the invention Position Updating flow process issues the tracking parameter flow process and comprises:
301, UE sends position updating request to MME;
302, MME carries out authentication to position updating request;
303, after authentication was passed through, MME initiated to upgrade the UPE request to UPE;
304, UPE upgrades and to the MME feedback response message;
305, MME accepts request to the position renewal that the UE feedback comprises tracking parameter;
306, UE upgrades to the MME feedback position and finishes message.
Three, utilize Service Request flow process to issue tracking parameter:
UE is in normal running, in order to obtain the business that needs, usually need to send service requesting information, this information can bring core net node by the NAS layer, no matter whether service request is successful, all will return a confirmation Service Request ACK, in the present embodiment, tracking parameter is carried among the confirmation Service Request ACK and feeds back to UE.
Introduced three kinds of modes that issue tracking parameter above, adopted other NAS message can reach the purpose of the embodiment of the invention equally, flow process is similar substantially.
Introduce the flow process that UE reports tracking parameter below:
When UE obtains and preserve tracking parameter, for example follow the tracks of sign, UE should follow the tracks of to identify to be carried in article one message and be sent to access network node afterwards, after access network node receives article one message from UE, check earlier whether tracking parameter is arranged, if have, then can start signaling tracing to this UE.
Be understandable that according to the formatting difference of following the tracks of sign, access network node can also check whether the numerical value of the tracking parameter in article one message is 1, if then start the signaling tracing to this UE immediately.
Access network node can be followed the tracks of earlier after getting access to the tracking sign temporarily, wait that the tracking parameter that gets access to other just can carry out formal tracking afterwards, other tracking parameter comprises: UE identifier (UEIdentity), tracking depths (Trace Depth), interface message (List of interfaces to trace), trace session ID (Trace Reference), track record session id (Trace Recording SessionReference), event identifier (Trace Event) etc. can determine according to the actual requirements.
Wherein, the access network node step of obtaining other tracking parameter comprises:
In the UMTS system, can be issued to RNC to the tracking parameter of relevant this UE with message between the RNC by core net node.And in the LTE system, substantially also adopt similar mode.It is considered herein that after access network node and core net node were set up S1 and be connected, core net node can utilize the message on this interface to bring eNodeB tracking parameter.At present in the LTE system, core net in continuing to use UMTS is called tracking (the CN Invoke Trace) message, we also advise using on the S1 interface a kind of customer equipment context foundation (S1 UE context setup) message that is called to give access network node core net node about the information band of this UE, generally carry the roaming restricted information in this message, security information, UE ability information etc.The effect of this message flow generally is that the information with relevant UE is delivered on the access network node by the S1 interface from core net, and access network node can use these information to set up carrying, perhaps encryption and decryption etc.This message flow generally occurs in to be set up between access network node and the core net node after signaling is connected.
After network side changed to the tracking of UE or cancels or reset, network side should in time be notified UE, and relevant tracking Control is consistent between network side and the UE to keep.
In the present embodiment, change comprises to be upgraded and two kinds of situations of cancellation:
One, upgrade tracking parameter:
After detecting tracking parameter and being updated, network side notice UE carries out the tracking parameter method for updating and generally comprises:
1, UE is in activated state:
UE has under the situation about being connected with network, and HSS can initiatively issue change message and give core net node.Because UE is in network connection state, core net node will trigger and issue flow process to access network node, such as adopting CN Invoke Trace message (utilizing Trace Propagation Parameters sign wherein) or S1 context setup message (utilizing newly-increased Trace parameter field).Access network node can be selected whether will be handed down to UE to the tracking parameter of change, if desired, then can issue UE by the control channel of eating dishes without rice or wine.
Also can be network side after learning that tracking parameter changes, require the UE flow process of attach again by initiating one, allow UE carry out attach again, in the attach process, utilize attach accetp message to give UE the tracking parameter information band of change.
2, UE is in Idle state:
Because UE sets up signaling with network side and is not connected, thus can't in time notify UE with changed information, this time, to wait until that generally UE transfers activated state to from Idle state after, after just UE and network connect, will change content by network side and issue UE.This process and above-mentioned by the NAS message between network side and the UE tracking parameter or follow the tracks of sign to issue the method for UE consistent.Generally also be the attachment flow by UE, the position is new technological process more, and bands such as service request flow process go down.
Also can initiatively initiate paging flow process, find UE by network side at this UE, and in the paging flow process the tracking parameter of change or follow the tracks of sign and bring UE.
3, other attitude:
Not start or be not attached to core net node of UE, and UE is neither activated state neither Idle state, the then information of this UE not on core net node this moment.Have only so when network attachment takes place UE by the time, core net node takes out tracking parameter from HSS, again tracking parameter is issued to access network node.
In several situations of foregoing description, can not have the participation of HSS, and directly carry out the renewal of tracking parameter by EMS, perhaps obtain from other node.
Two, cancellation tracking parameter:
When EMS will cancel trace flow to certain UE, following several situation is arranged:
1, UE is in activated state:
HSS can trigger a proactive process and give core net node, core network node triggers issues flow process to access network node, because UE is in activated state, UE can accept the control command of access network node, access network node can be by the trace labelling of aerial control channel cancellation UE, and access network node cancellation simultaneously is to the tracking of this UE.
Idiographic flow comprises as shown in Figure 4:
401, EMS sends cancellation and follows the tracks of the instruction of certain UE to HSS;
402, HSS revises the relevant Trace parameter with this UE;
403, HSS initiates a proactive process, the change of notice core net node tracking parameter, and the UE Trace parameter extraction that core net can be new with this comes out;
404, inform the cancellation that access network node is followed the tracks of certain UE by CN Invoke Trace message (utilizing Trace Propagation Parameters sign wherein) or S1 context setup message (utilizing wherein newly-increased Trace parameter field);
405, layer1 or the Layer2 passage by eating dishes without rice or wine informs that UE revises the previous Trace parameter that receives;
Cancel tracking simultaneously to this UE;
406, UE equipment is revised the Trace parameter of storing on it automatically, comprises that cancellation UE goes up Flag sign in the Trace information;
407, if initiate other operation flow, such as the RRC request, the trace bit Flag on the UE changes, can not cause access network node to be followed the tracks of again.
Also can be network side learning that tracking parameter cancelled, require the UE flow process of attach again, allow UE carry out attach again, in the attach process, utilize attach accetp message to give UE following the tracks of the cancellation information band by initiating one.
2, UE is in Idle state:
Specifically be subdivided into following several situation:
Because UE does not set up signaling with network side and is connected, so can't be in time notify UE with the cancellation trace information, this time, to wait until that generally UE transfers activated state to from Idle state after, after just UE and network connect, will cancel trace information by network side and issue UE.This process and above-mentioned by the NAS message between network side and the UE tracking parameter or follow the tracks of sign to issue the method for UE consistent.Generally also be the attachment flow by UE, the position is new technological process more, and bands such as service request flow process go down.
Also can initiatively initiate paging flow process, find UE, and in the paging flow process, bring UE the cancellation trace information by network side at this UE.
Also has a kind of method, that is exactly after network side has been cancelled the tracking parameter of UE, directly do not notify UE by above method, but when UE transfers activated state to from the free time, access network node can from the CN node judge whether cancel to it tracking (generally speaking, if core net node has the tracking parameter of this UE, then after access network node and CN set up S1 and are connected, CN can be handed down to access network node to tracking parameter, this issues can be initiatively to issue, and also can be that access network node obtains to the core net node inquiry.If do not have tracking parameter control, then can not issue tracking parameter to access network node.Perhaps access network node is initiatively inquired the information that the back does not have acquisition to follow the tracks of).If cancel, then just by the tracking flag of the control channel cancellation UE that eats dishes without rice or wine, deletion simultaneously is the RRC message of track record before for access network node.Here require article one RRC message of access network node track record after the S1 interface is set up, to report the OMC of oneself after judging whether to need to follow the tracks of again, idiographic flow as shown in Figure 4:
Wherein the step 401 described to step 403 and the last embodiment of step 401 is consistent to step 403;
404: when UE forwards activated state to from Idle state, be connected with S1 between the core net node setting up access network node, after S1 connects foundation, inform that by CN Invoke Trace message (utilizing TracePropagation Parameters sign wherein) or S1 context setup message (utilizing wherein newly-increased Trace parameter field) access network node to the cancellation that certain UE follows the tracks of, has several situations here:
If 1. tracking configuration and Control Parameter at this UE are arranged on the core net node, then are handed down to access network node by the S1 interface message;
If 2. because of the trace command of having cancelled this UE, there is not to preserve tracking parameter in the core net node, so also just not having tracking parameter is issued to access network node at this UE.Access network node also can be judged in view of the above so no longer needs this UE is followed the tracks of;
3. core net node can be given access network node by the active issuing message, directly tells access network node to cancel certain UE is followed the tracks of.
405: utilize the channel of eating dishes without rice or wine between access network node and the UE cancellation tracking to be told notice UE to UE no longer keeps trace labelling; Access network node learn follow the tracks of cancellation after, will this UE not followed the tracks of during next operation flow.
Step 406 to 407 with a last embodiment in step 406 to 407 consistent, repeat no more.
In the embodiment of the invention, UE obtains and follows the tracks of sign or tracking parameter, also can directly be obtained by the access network node place.In this case, the signaling by the Access Layer between access network node and the UE obtains.This follows the tracks of sign or parameter may be the setting of access network node self networks management system, also may be by other network nodes, and for example core net node or other relevant access network nodes pass over.
In a last embodiment, mention when UE is in activated state, core net node change tracking parameter, and be issued to access network node, access network node is handed down to the embodiment that UE comes to this to tracking parameter by eating dishes without rice or wine again.Be understandable that UE obtains tracking parameter or sign also can be from access layer information, such as obtains in the RRC message.
