Embodiment
Fig. 1 is the basic step of the unnecessary switching handling method of the present invention, as shown in the figure, comprising:
Step 101: the fault type identifying unnecessary switching;
Step 102: add up the number of times that various unnecessary switch failure type occurs;
Step 103: when the number of times that a kind of unnecessary switch failure type occurs reaches setting thresholding, send the request message of the corresponding parameter of adjustment.
Wherein, the fault type of unnecessary switching can comprise: to different system adjacent cell switching time too early, excessively late or exist simultaneously and switched evening too early and to homologous ray adjacent area to different system adjacent cell switching time to homologous ray adjacent area switching time; Concrete, the fault type of unnecessary switching can be determined according to handover report (HO Report) message comprising handover report type (HO Report Type), switching type (HO Type) and candidate E-UTRAN cell list.Setting thresholding comprehensively can be determined according to switching times in user's request and existing network and the unnecessary switching occurrence frequency of different system.
Below for LTE communication system, the concrete methods of realizing of the fault type identifying unnecessary switching in above-mentioned steps 101 is described, as shown in Figure 2, comprises:
Step 201:UE is from LTE network community A to after different system adjacent cell B switches, and the eNodeB at B place, community notifies that UE carries out coverings measurement;
Described covering is measured at least to comprise and is measured in the chlamydate community of current location;
Step 202:UE carry out measure cover and report measurement results to the eNodeB at B place, community;
Described measurement result at least comprises candidate E-UTRAN cell list, and this candidate E-UTRAN cell list is with the mark in the chlamydate E-UTRAN community of current location.
Step 203: the eNodeB at B place, community according to measurement result determination handover report information and sending to A place, community eNodeB;
Wherein, handover report message comprises: handover report type, switching type and candidate E-UTRAN cell list; Handover report message can be carried at MME Direct Information Transfer(MME direct-sending message) in send to A place, community eNodeB.
Handover report type may be used for indicating whether this switching is the unnecessary switching of different system; Switching type may be used for indicating this switching to be the switching which kind of different system adjacent cell is LTE network arrive; Its particular content all has regulation in 3GPP agreement, repeats no more.
Step 204: A place, community eNodeB judges whether it is the unnecessary switching of different system according to handover report message, if so, then the particular type of this different systematic evaluation is determined further, such as: different system cell is UTRAN, or GERAN etc., and jump to step 205; If not, then terminate current process;
Concrete, can judge whether it is the unnecessary switching of different system according to the handover report type in handover report message, distinguish this particular type switched according to switching type, carry out statistical disposition respectively.Time such as: when handover report type is the unnecessary switching of the Unnecessary HO to different system of another RAT(), distinguishing this particular type switched according to switching type is again LTE to UTRAN(LTE to UTRAN), or LTE to GERAN(LTE to GERAN), then carry out statistical disposition respectively.
Step 205: the eNodeB at A place, community, according to candidate E-UTRAN cell list, judges the fault type of the unnecessary switching of different system; Concrete:
If candidate E-UTRAN community only comprises handover source community, illustrate generation different systematic evaluation after E-UTRAN handover source community still can be detected, now UE also should continue to reside in LTE network, and does not need to switch to different grid too early.So determine that the fault type of unnecessary switching is for too early to different system adjacent cell switching time, is designated as this kind of different system adjacent cell switching time too early in such cases;
If candidate E-UTRAN community does not comprise handover source community, but comprise other E-UTRAN communities, and there is neighboring BS relationship one of other E-UTRAN communities described and handover source community, illustrate and E-UTRAN handover source community can not be detected after different systematic evaluation, there is not the too early situation of switching to different system adjacent cell; And the adjacent area of E-UTRAN handover source community can be detected, illustrate that there is available E-UTRAN adjacent area switching point place E-UTRAN handover source community, but do not switch.So this kind of situation determines that the fault type of unnecessary switching is for excessively late to homologous ray adjacent area switching time, is designated as E-UTRAN adjacent area switching time excessively late;
If candidate E-UTRAN community comprises E-UTRAN handover source community and other E-UTRAN communities simultaneously, and there is neighboring BS relationship one of other E-UTRAN communities described and handover source community, then according to above-mentioned analysis, this kind of situation determines that the fault type of lower unnecessary switching is for existing to different system adjacent cell switching time too early and excessively late to homologous ray adjacent area switching time simultaneously, is designated as different system adjacent cell switching time respectively too early and excessively late to E-UTRAN adjacent area switching time.
In addition, if comprise E-UTRAN community in candidate E-UTRAN community, but there is no neighboring BS relationship with handover source community, then carry out the leakage of E-UTRAN neighboring BS relationship according to prior art and join process, no longer relate in the present invention.
Above-mentioned steps 103, when the number of times that a kind of unnecessary switch failure type occurs reaches setting thresholding, sends a request message, the parameter that request adjustment is corresponding.Specific implementation and principle as follows:
For the unnecessary switching of different system caused too early to different system adjacent cell switching time, for LTE communication system, the entry condition formula according to B2 event:
Mn+Ofn-Hys>Thresh2
Wherein: Mn is the measurement result of different system adjacent cell;
Ofn is the frequency shift (FS) of different system adjacent cell;
Hys is event lag parameter;
Thresh2 is event thresholds value;
Above-mentioned parameter can obtain by middle Mn from measurement report, and Ofn, Hys, Thresh2 can be configured by background net management, belong to the state of the art, repeat no more.
When above-mentioned condition formula is set up, UE can switch to different system adjacent cell.More difficult in order to make user Xiang Yi system adjacent cell switch, this event thresholds value Thresh2 is more difficult to be reached to need adjustment parameter to make.Concrete, in the embodiment of the present invention, when the number of times occurred too early to different system adjacent cell switching time reaches setting thresholding, base station sends the request turning the frequency shift (FS) Ofn of different system adjacent cell down to background net management, background net management turns Ofn down after receiving this request, reach the object of the different system adjacent cell handoff threshold under adjustment different frequent points, thus optimize the unnecessary switching problem of different system of the type.In addition, background net management sends the successful message of parameter adjustment to base station after turning Ofn down, after base station receives the successful message of parameter adjustment, will arrive the too early number of times zero setting of different system adjacent cell switching time.
For the unnecessary switching of different system excessively caused evening to homologous ray adjacent area switching time, for LTE communication system, the entry condition formula according to A3 event:
Mn+Ofn+Ocn-Hys>Mp+Ofp+Ocp+Off
Wherein: the measurement result of Mn adjacent area;
The frequency shift (FS) of Ofn adjacent area;
The particular offset of Ocn adjacent area;
The measurement result of Mp Serving cell;
The frequency shift (FS) of Ofp dominant frequency;
Ocp Serving cell offsets;
Hys event lag parameter;
Off event offset parameter;
Thresh2 event thresholds value;
Above-mentioned parameter can obtain by middle Mn and Mp from measurement report, and Ofn, Ocn, Ocp, Hys, Off, Thresh2 can be configured by background net management, belong to the state of the art, repeat no more.
When above-mentioned condition formula is set up, UE can switch to homologous ray adjacent area.In order to make, user is easier to be switched to E-UTRAN adjacent area, needs adjustment parameter that this formula is more easily met.Concrete, in embodiments of the present invention, when the number of times crossing late appearance to homologous ray adjacent area switching time reaches setting thresholding, base station tunes up E-UTRAN adjacent area particular offset Ocn to background net management transmission and asks, background net management tunes up adjacent area particular offset Ocn after receiving this request, reach the object adjusting single E-UTRAN adjacent area handoff threshold respectively, thus optimize the unnecessary switching problem of different system of the type.In addition, after background net management tunes up adjacent area particular offset Ocn, send the successful message of parameter adjustment to base station, after base station receives the successful message of parameter adjustment, will the too early number of times zero setting of different system adjacent cell switching time be arrived.
Too early and excessively late to homologous ray adjacent area switching time for existing to different system adjacent cell switching time simultaneously, the frequency shift (FS) Ofn of different system adjacent cell can be turned by the way simultaneously down, tune up the particular offset Ocn of E-UTRAN adjacent area, reach the different system adjacent cell of adjustment and the object of E-UTRAN adjacent area handoff threshold, make that user is easier to be switched to E-UTRAN adjacent area and more difficult to different systematic evaluation.Thus optimize the unnecessary switching problem of different system of the type.In embodiments of the present invention, for existing to different system adjacent cell switching time too early and cross the fault type of late this unnecessary switching to homologous ray adjacent area switching time simultaneously, statistics is for too early to different system adjacent cell switching time and to arrive E-UTRAN adjacent area switching time excessively late respectively; That is: when appearance exist simultaneously too early and when crossing late to homologous ray adjacent area switching time to different system adjacent cell switching time, different system adjacent cell switching time is added 1 too early and to the statistics number that homologous ray adjacent area switching time is excessively late respectively, processes as a kind of measurement type when no longer independent.

If candidate E-UTRAN community does not comprise handover source community, but comprise other E-UTRAN communities, and there is neighboring BS relationship one of other E-UTRAN communities described and handover source community, illustrate and E-UTRAN handover source community can not be detected after different systematic evaluation, there is not the too early situation of switching to different system adjacent cell; And the adjacent area of E-UTRAN handover source community can be detected, illustrate that there is available E-UTRAN adjacent area switching point place E-UTRAN handover source community, but do not switch.So this kind of situation determines that the fault type of unnecessary switching is for excessively late to homologous ray adjacent area switching time, is designated as E-UTRAN adjacent area switching time excessively late;
If candidate E-UTRAN community comprises E-UTRAN handover source community and other E-UTRAN communities simultaneously, and there is neighboring BS relationship one of other E-UTRAN communities described and handover source community, then according to above-mentioned analysis, this kind of situation determines that the fault type of lower unnecessary switching is for existing to different system adjacent cell switching time too early and excessively late to homologous ray adjacent area switching time simultaneously, is designated as different system adjacent cell switching time respectively too early and excessively late to E-UTRAN adjacent area switching time.
In addition, if comprise E-UTRAN community in candidate E-UTRAN community, but there is no neighboring BS relationship with handover source community, then carry out the leakage of E-UTRAN neighboring BS relationship according to prior art and join process, no longer relate in the present invention.
Sending module, is specially for sending corresponding request message according to the fault type of the unnecessary switching reaching setting thresholding:
When the number of times occurred too early to different system adjacent cell switching time reaches setting thresholding, send the request turning the frequency shift (FS) Ofn of different system adjacent cell in this down to gateway backstage;
When the number of times crossing late appearance to homologous ray adjacent area switching time reaches setting thresholding, send the request tuning up the particular offset Ocn of homologous ray adjacent area to gateway backstage.

Step 702:UE carry out measurement cover and report measurement results to target cell base station;
Described measurement result at least comprises candidate E-UTRAN cell list, and this candidate E-UTRAN cell list is with the mark in the chlamydate E-UTRAN community of current location.
Step 703: target cell base station according to measurement result determination handover report information and sending to source cell base station;
Wherein, handover report message comprises: handover report type, switching type and candidate E-UTRAN cell list; Handover report message can be carried at MME Direct Information Transfer(MME direct-sending message) in send to source cell base station.
Step 704: source cell base station judges whether it is the unnecessary switching of different system according to handover report message, if so, then determines the particular type of this different systematic evaluation further, such as: different system cell is UTRAN, or GERAN etc., and jump to step 705; If not, then terminate current process;
Concrete, can judge whether it is the unnecessary switching of different system according to the handover report type in handover report message, distinguish this particular type switched according to switching type, carry out statistical disposition respectively.
Step 705: source cell base station, according to candidate E-UTRAN cell list, judges the fault type of the unnecessary switching of different system; Concrete:
If candidate E-UTRAN community only comprises handover source community, then determine that the fault type of unnecessary switching is for too early to different system adjacent cell switching time, is designated as this kind of different system adjacent cell switching time too early;
If candidate E-UTRAN community does not comprise handover source community, but comprise other E-UTRAN communities, and there is neighboring BS relationship one of other E-UTRAN communities described and handover source community, then determine that the fault type of unnecessary switching is for excessively late to homologous ray adjacent area switching time, is designated as E-UTRAN adjacent area switching time excessively late;
If candidate E-UTRAN community comprises E-UTRAN handover source community and other E-UTRAN communities simultaneously, and there is neighboring BS relationship one of other E-UTRAN communities described and handover source community, the fault type then determining unnecessary switching, for existing to different system adjacent cell switching time too early and excessively late to homologous ray adjacent area switching time simultaneously, is designated as different system adjacent cell switching time too early and excessively late to E-UTRAN adjacent area switching time respectively.
Step 706: source cell base station judges to add up and determine different system adjacent cell switching time whether reach setting thresholding too early and to the number of times that homologous ray adjacent area switching time crosses late appearance, and does corresponding process according to judged result; Concrete:
When the number of times too early to different system UTRAN adjacent area switching time reaches setting thresholding, source cell base station sends the request turning the frequency shift (FS) Ofn of different system UTRAN adjacent area down to background net management, UE is switched to different system adjacent cell GERAN more difficult, and will the too early number of times zero setting of different system UTRAN adjacent area switching time be arrived after the successful message of parameter adjustment that platform webmaster sends upon receipt;
When the number of times excessively late to E-UTRAN adjacent area switching time reaches setting thresholding, source cell base station sends the request tuning up the particular offset Ocn of E-UTRAN adjacent area to background net management, UE is switched to adjacent area E-UTRAN easier, and will the excessively late number of times zero setting of E-UTRAN adjacent area switching time be arrived after the successful message of parameter adjustment that platform webmaster sends upon receipt;
When to different system UTRAN adjacent area switching time too early and when all not reaching setting thresholding to the number of times in E-UTRAN adjacent area switching time evening excessively, end current process.
