Detailed description of the invention
The core concept of the present invention is: provide the detection scheme of mobility parameter matching performance between a kind of neighbor cell, LTE/LTE-A system carries out between eNB the detection of the mobility parameter matching performance of two neighbor cells, if it find that the mobility parameters between two neighbor cells does not mate, after then can redefining the increment size of mobility parameters amendment between two neighbor cells, initiate the mobility parameters amendment negotiations process that cause value is " handover optimization ".
The detection method of mobility parameter matching performance provided by the invention can adopt the following technical scheme that
One, detect at source moving property parameter matching performance
Source eNB can when needs, as will mobility parameters amendment negotiations process before or mobility parameters amendment consult complete after, or when finding mobility problem (as found pingpang handoff, too late switching etc.), or periodically initiate mobility parameter matching performance detection process to target eNB, this process comprises the following steps:
Step one, source eNB sends mobility parameters amendment request message to target eNB, request message carries cause value " mobility parameter matching performance detection ", additionally goes back the mobility parameters currency of portability cell-of-origin and/or the allowed band of the mobility parameters of cell-of-origin；
In this step, also can initiate the request of mobility parameter matching performance detection in the following way to target eNB: carry cause value " load balancing " or " handover optimization ", the increment size that cell-of-origin and Target cell side shifting parameter will be revised, and the increment size that cell-of-origin and Target cell side shifting parameter will be revised is all 0, additionally go back the mobility parameters currency of portability cell-of-origin and/or the allowed band of the mobility parameters of cell-of-origin.
Step 2, after target eNB receives the request message of source eNB, if the cause value carried in request message is " mobility parameter matching performance detection ", then return mobility parameters amendment and confirm message, confirm the mobility parameters currency carrying Target cell in message, additionally go back the allowed band of the mobility parameters of portability Target cell；
Step 3, after source eNB receives the confirmation message of target eNB, carries out the mobility parameter matching performance detection of two neighboring intervals according to information such as the mobility parameters currencys of the mobility parameters currency and cell-of-origin oneself that confirm the Target cell carried in message.
Wherein, when source eNB detects that the overlapping region on the mobility border of cell-of-origin and Target cell can not Satisfying Matching Conditions, for instance, the threshold values that network management configuration is certain can be passed through, when overlapping region too small or excessive time then think that the mobility parameters of two neighboring intervals does not mate.It is of course also possible to arrange whether some other matching condition mates to the mobility parameters judging cell-of-origin and Target cell, depend on actual need and determine.
If the mobility parameters of two neighboring intervals does not mate, in order to solve problem, source eNB can initiate, to target eNB, the mobility parameters amendment negotiations process that cause value is " handover optimization ".
Two, detect at target side moving property parameter matching performance
Source eNB can when needs (before or after revising negotiations process at mobility parameters, or when finding mobility problem (as found pingpang handoff, too late switching etc.)) or periodically to target eNB initiation mobility parameter matching performance detection process.This process comprises the following steps:
Step one, source eNB sends mobility parameters amendment request message to target eNB, and can initiate the request of mobility parameter matching performance detection in the following way to target eNB:
1) request message is carried the mobility parameters currency of cause value " mobility parameter matching performance detection ", cell-of-origin, additionally goes back the allowed band of the mobility parameters of portability cell-of-origin；
2) request message carries cause value " load balancing " or the mobility parameters currency of " handover optimization ", cell-of-origin, the increment size that cell-of-origin and Target cell side shifting parameter will be revised, and the increment size that cell-of-origin and Target cell side shifting parameter will be revised is all 0, additionally go back the allowed band of the mobility parameters of portability cell-of-origin；
Step 2, after target eNB receives the request message of source eNB, if the parameter situation carried in request message is: 1) cause value carried in request message is " mobility parameter matching performance detection ", or 2) cause value that carries is " load balancing " or " handover optimization " in request message, and carry cell-of-origin and increment size that Target cell side shifting parameter will be revised, and the two increment size is all 0, the then mobility parameters currency according to the cell-of-origin carried in request message, and the information such as the mobility parameters currency of Target cell oneself carries out the mobility parameter matching performance detection of two neighboring intervals, and the testing result of mobility parameter matching performance can be returned in the following way to source eNB:
A) return mobility parameters amendment and confirm message, if matching detection is found that problem, the confirmation message returned is carried the mobility parameters currency of Target cell, additionally goes back the allowed band of the mobility parameters of portability Target cell.If matching detection is not pinpointed the problems, without the mobility parameters currency of Target cell in the confirmation message returned；
B) return mobility parameters amendment and confirm message, if matching detection is found that problem, the confirmation message returned is carried cause value " mobility parameter matching performance detection does not pass through ", additionally goes back the mobility parameters currency of portability Target cell and/or the allowed band of the mobility parameters of Target cell；If matching detection is not pinpointed the problems, without cause value " mobility parameter matching performance detection does not pass through " in the confirmation message returned, but the mobility parameters currency of Target cell and/or the allowed band of the mobility parameters of Target cell can be carried；
If c) matching detection is not pinpointed the problems, return mobility parameters amendment and confirm message, confirm message can carry the mobility parameters currency of Target cell and/or the allowed band of the mobility parameters of Target cell；If matching detection is found that problem, then return mobility parameters amendment failed message, failed message can carry allowed band and/or the cause value " mobility parameter matching performance detection does not pass through " of the mobility parameters currency of Target cell and/or the mobility parameters of Target cell.
Step 3, source eNB receives the target eNB confirmation message returned or failed message, and judges whether the mobility parameters of two neighboring intervals mates according to the corresponding manner of the testing result returning mobility parameter matching performance of target eNB in step 2:

The essence of the program is to increase matching detection in existing amendment negotiations process, and namely target side base station is after finishing current existing detection, is further added by a matching detection.
Step 3, after source eNB receives the failed message of target eNB, if failed message carrying cause value " mobility parameter matching performance detection does not pass through ", then it represents that the new mobility parameters that the reason causing the amendment negotiations process of this mobility parameters failed is two neighboring intervals does not mate.
