Embodiment
For the purpose that makes the embodiment of the invention, technical scheme, and advantage clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, the embodiment of the invention is further described.
The inventor finds because present mobile management entity (Mobility Management Entity, MME) do not preserve the Trace relevant information of UE on, even source base station (Source eNB, S-eNB) in HandoverRequest message, the Trace relevant information of UE is carried to target BS (Target eNB, T-eNB), the activation Trace of UE has been obtained continuity in present Access Network side, but it is the situation that UE has selected a new core net gateway that also there is MME in the switching that is based on X2 interface, MME does not continue to trigger the foundation of the Trace of UE on new gateway in this case, causes Trace to interrupt in core net.
Further, the inventor also finds for the switching based on the S1 interface, owing to changed MME, base station (eNodeB, eNB) and the core net gateway, because source base station (Source eNB, S-eNB) do not require to carry the Trace relevant information in the message Handover Required message in switching, and source MME does not have the Trace relevant information in the context of the UE that preserves of UE yet, so just making Trace activate all interrupts on access network node eNB and core net node (GW, Gate Way).
For realizing the continuous of Trace, the embodiment of the invention provides corresponding method and apparatus and system, and details are as follows:
The embodiment of the invention one:
As shown in Figure 1, step S101, the UE context that reception sources MME sends, described UE context carries trace Trace relevant information.Specifically comprise: the UE context that target MME reception sources MME sends, this UE context comprises the Trace relevant information, and for example trace is with reference to Trace reference, and trace type Trace type triggers sign trigger ID, is used to activate Trace information.
Step S102 according to described UE context, activates Trace.Comprise that specifically target MME sends to corresponding network entity such as core net gateway and base station according to the Trace relevant information in the above-mentioned UE context with Trace active information Trace activation, to activate the Trace on this corresponding network entity.
Need to prove, above-mentioned target MME and source MME only are the logic entity titles that need summarize owing to functional description, in fact, target MME and source MME can be same physical entities, for the MME entity that does not need to distinguish source MME and target MME function, the foregoing description one can directly be described as the contextual information that MME preserves UE, and described UE context carries trace Trace relevant information, and MME is according to the Trace information of described UE context activation corresponding network entity.Need to prove for the Trace relevant information, this Trace relevant information is stored in the transmission that is used for indicating subsequent flows journey Trace active information in the UE context, activate Trace, this Trace relevant information can comprise: trace is with reference to Trace reference, trace type Trace type triggers sign trigger ID.
Embodiment two
At the switching based on X2 interface, promptly source eNB directly sends out handoff request message by X2 interface and gives target eNB, is prepared bearing resource and then is implemented handoff procedure by target eNB.Because MME is not changed in this switching, source eNB can carry the Trace active information in handoff request message, so that target eNB continues to activate Trace.
MME is by carrying the Trace relevant information in the UE context, with reference to Trace reference, trace type Trace type triggers sign trigger ID etc. as trace, and MME is according to the Trace information on this UE context activation core net gateway.Specifically comprise: after finishing based on the switching of X2 interface, selected a new core net gateway if MME is UE, MME will be according to the Trace on the activation of the Trace relevant information in this UE contextual information new gateway.The step of Trace on this activation new gateway specifically comprises:
The path handoff request message Path Switch Request that MME receiving target eNB sends, set up the carrying of core-network side for UE, if being UE, MME selected a new gateway, then the Trace relevant information in the UE context is carried on the carrying that sends to gateway and sets up in the request message, so just on new core net gateway, activated the Trace of UE.Further, MME also can judge the Trace information whether activation is arranged in the context of UE.
As shown in Figure 2, handoff procedure is described below for example:
S201, S202 are when switching based on X2 interface, and switching is prepared Handover Preparation and switch execution Handover Execution process same as the prior art, does not repeat them here;
S203, target eNB are after finishing the X2 interface switching, to MME transmit path handoff request PathSwitch Request message;
S204, MME receive Path Switch Request, set up the carrying of core-network side for UE, if being UE, MME selected a new gateway, then MME judges the Trace active information that whether has in the context of UE, if have, then the carrying that this information is carried at gateway is set up in the request message, has so just activated the Trace of UE on gateway.
S205, set up the carrying of network side after, MME is to eNB transmit path handover acknowledge Path SwitchACK.
By the method that adopts the foregoing description to provide, in the UE context that MME preserves, increase the Trace relevant information, after X2 switched, if MME has selected a new core net gateway to UE, MME can be by sending the Trace active information continues to activate UE on new gateway Trace.Realize the continuity of Trace information, helped the network operation maintenance and management.
Embodiment three
In the context of the UE that target MME preserves, increase the active information of Trace, like this in switching the process of preparing, source MME can give target MME with the UE context transfer, and target MME has also activated Trace simultaneously in new core net gateway when setting up network side load.In addition, source eNB requires also can will send to the target eNB side by core net at the Trace of source eNB active information among the message Handover Required in the switching of sending for source MME, activates so that target eNB is proceeded Trace.
Below with the specific implementation that example is described embodiment three that switches to of S1 interface:
As shown in Figure 3,
After S301, source eNB initiate the switching of S1 interface, send switching to source MME and require HandoverRequired message, be carried at the Trace information that has activated on the eNB of source, specifically can comprise following two kinds and carry mode:
The Trace active information is placed on source eNB in the container container of target eNB, this container is meant to be included in and switches in the message, be transparent to the target access network node from the source access network node through core net node, in transmission course, core net node can not resolved this IE, concrete this example, and being meant does not need MME to resolve, directly be transparent to target eNB in core net, target eNB just can be resolved this container container.
Perhaps,
As an independent message IE, this IE is to resolve through core network entity in core net with the Trace active information, and for example MME resolves it.
S302, source MME receive Handover Required message, send to transmit re-positioning request ForwardRelocation Request message to target MME, and this message is carried the context of UE.Because the Trace relevant information of in store UE in the context of UE, this Trace relevant information just is sent to target MME place like this.
After S303, target MME receive Forward Relocation Request message, judge whether to allow UE to switch, if allow to switch and selected a core net gateway for UE, then target MME activates Trace according to the Trace relevant information in the UE context by the core net loading establishing process on gateway.Comprise that specifically target MME sends carrying to the core net gateway and sets up request message Bearer CreateRequest, this carrying is set up and is carried the Trace active information in the request message.
S304, target MME receive carrying and set up response Bearer Create Response message.
S305, target MME send handoff request message Handover Request to target eNB, require eNB to prepare the wireless side carrying, and this Handover Request carry the Trace active information.According to the＜1〉step the mode of carrying, this Handover Request carries the Trace active information following dual mode:
If the＜1〉step in, the Trace active information is to carry in the container, because this container is not resolved by network entity, then in the 5th step, the Trace active information is carried on source eNB in the container container of target eNB, to the target eNB side, some the record reference identification in this Trace active information are consistent with source.
If the＜1〉in the step, Trace information is independent IE, because this IE is what need to be resolved in core net, resolves as MME, therefore in the 5th step, Trace information is an independent IE after resolving and revise through core network entity.
After the S306-S308 target eNB finishes carrying, return accordingly to source and to reply, do not repeat them here.
S309, switching are carried out.
The process of carrying of above-mentioned Trace information equally also is fit to different system and switches.

Below in the switching with the S1 interface, switching the situation that requires not carry in the Handover Required message Trace active information is the specific implementation that example is described embodiment four.Need to prove that this is not carry the Trace active information in the Handover Required message based on the switching flow of S1 interface and the description difference of the switching flow among the embodiment three, as shown in Figure 4:
S401, source eNB initiate handoff request through behind the switch decision to source MME, but require not comprise among the message Handover Required Trace active information on the eNB in switching.
S402, source MME send to target MME and transmit RELOCATION REQUEST message Forward RelocationRequest, carry the context that source MME goes up the UE that preserves in this message, carry the Trace relevant information in this UE context.
S403, target MME receive this forwarding RELOCATION REQUEST message, selected a new core net gateway for UE simultaneously, initiate to set up the carrying request to this gateway, according to the Trace relevant information in the context of UE, target MME can set up in carrying and carry the Trace active information in the request message, so that activate Trace on new gateway.
S404, target MME receive carrying and set up response message.
S405, target MME send handoff request Handover Request to target eNB, and request target eNB prepares the wireless side carrying.Target MME can carry the Trace active information according to the Trace information in the UE context in HandoverRequest message, so that at target eNB side activating Trace.
After the S406-S408 target eNB finishes carrying, return accordingly to source and to reply, do not repeat them here.
S409, switching are carried out.
The above-mentioned process of carrying equally also is fit to different net system switching process.
The foregoing description is by increasing the Trace relevant information in the UE context of preserving at MME, make target MME can continue to activate the Trace of target eNB and intended gateway according to the Trace relevant information, the relevant parameter in the Trace of this moment is distributed by target MME or is defined.Adopt the foregoing description to realize the continuity of Trace, make network can understand the operation situation of equipment.In addition, source eNB also can carry the Trace active information and give target side in handoff request, and according to two kinds of different modes of carrying, the relevant parameter in the Trace of target side can continue to keep the distribution of source MME or define distribution by target MME.
