Core concept of the present invention is: the detection scheme that mobility parameter matching between a kind of neighbor cell is provided, in the LTE/LTE-A system, carry out the detection of the mobility parameter matching of two neighbor cells between eNB, if finding two mobility parameters between neighbor cell does not match, then can be after redefining the increment size of mobility parameter modification between two neighbor cells, initiating cause value is the mobility parameter modification negotiations process of " handover optimization ".
The detection method of mobility parameter matching provided by the invention can adopt following technical scheme:
One, carries out the detection of mobility parameter matching at source
Source eNB can be in needs, as before will the negotiations process of mobility parameter modification or after the mobility parameter modification is consulted to finish, or when finding mobility problem, (switch, cross switching in evening etc. as discovery table tennis), or periodically initiate mobility parameter matching testing process to target eNB, this process may further comprise the steps:
Step 1, source eNB sends mobility parameter modification request message to target eNB, carry cause value " detection of mobility parameter matching " in the request message, go back the allowed band of the mobility parameter of the mobility parameter currency of portability cell-of-origin and/or cell-of-origin in addition;
In this step, also can initiate the request of mobility parameter matching 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 all is 0, goes back the allowed band of the mobility parameter of the mobility parameter currency of portability cell-of-origin and/or cell-of-origin in addition.
Step 2, after target eNB is received the request message of source eNB, if the cause value that carries in the request message is " detection of mobility parameter matching ", then return mobility parameter modification acknowledge message, carry the mobility parameter currency of Target cell in the acknowledge message, go back the allowed band of the mobility parameter of portability Target cell in addition;

Wherein, the overlapping region that detects the mobility border of cell-of-origin and Target cell as source eNB can not Satisfying Matching Conditions, for example, can pass through the certain threshold values of network management configuration, thinks then that when the overlapping region is too small or excessive the mobility parameter of two neighboring intervals does not match.Certainly, some other matching condition also can be set judge whether the mobility parameter of cell-of-origin and Target cell mates, depend on actual need and decide.
If the mobility parameter of two neighboring intervals does not match, in order to deal with problems, source eNB can initiate the mobility parameter modification negotiations process of cause value for " handover optimization " to target eNB.
Two, carry out the detection of mobility parameter matching in target side
Source eNB can (as before or after the negotiations process of mobility parameter modification, or (switch, cross switching in evening etc.)) or periodically initiate mobility parameter matching testing process to target eNB as discovery table tennis when finding mobility problem in needs.This process may further comprise the steps:
Step 1, source eNB sends mobility parameter modification request message to target eNB, and can initiate the request of mobility parameter matching detection in the following way to target eNB:
1) carries the mobility parameter currency of cause value " detection of mobility parameter matching ", cell-of-origin in the request message, go back the allowed band of the mobility parameter of portability cell-of-origin in addition;
2) carry the mobility parameter currency of cause value " load balancing " or " handover optimization ", cell-of-origin in the request message, 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 all is 0, goes back the allowed band of the mobility parameter of portability cell-of-origin in addition;

A) return mobility parameter modification acknowledge message,, go back the allowed band of the mobility parameter of portability Target cell in addition if matching detects the mobility parameter currency that carries Target cell in the affirmation message of having found problem then having returned.If matching detects in the affirmation message do not pinpoint the problems then to return not the mobility parameter currency with Target cell;
B) return mobility parameter modification acknowledge message, carry cause value " detection of mobility parameter matching by " in the affirmation message found problem then to have returned if matching detects, go back the allowed band of the mobility parameter of the mobility parameter currency of portability Target cell and/or Target cell in addition; Be not with cause value " detection of mobility parameter matching by " in the affirmation message do not pinpoint the problems then to return if matching detects, but can carry the allowed band of the mobility parameter of the mobility parameter currency of Target cell and/or Target cell;
C), can carry the allowed band of the mobility parameter of the mobility parameter currency of Target cell and/or Target cell in the acknowledge message if matching detects and not pinpoint the problems then return mobility parameter modification acknowledge message; If matching detects the problem of having found, then return mobility parameter modification failed message, can carry the allowed band of mobility parameter of the mobility parameter currency of Target cell and/or Target cell and/or cause value " detection of mobility parameter matching by " in the failed message.
Step 3, affirmation message or failed message that source eNB receiving target eNB returns, and judge according to the corresponding manner that target eNB in the step 2 is returned the testing result of mobility parameter matching whether the mobility parameter of two neighboring intervals mates:
According to mode a, after source eNB receives the affirmation message of target eNB, judge according to the mobility parameter currency that whether has carried Target cell in the acknowledge message whether the mobility parameter of two neighboring intervals mates, if carried the mobility parameter currency of Target cell in the acknowledge message then represent that the mobility parameter of two neighboring intervals is unmatched, otherwise mate;
According to mode b, after source eNB receives the affirmation message of target eNB, judge according to whether having carried cause value " detection of mobility parameter matching not by " in the acknowledge message whether the mobility parameter of two neighboring intervals mates, if carried cause value " detection of mobility parameter matching not by " in the acknowledge message then represent that the mobility parameter of two neighboring intervals is unmatched, otherwise mate;
According to mode c,, represent that then the mobility parameter of two neighboring intervals is mated if source eNB receives the affirmation message of target eNB; If source eNB receives the failed message of target eNB, represent that then the mobility parameter of two neighboring intervals is unmatched.
If the mobility parameter of two neighboring intervals does not match, then in order to deal with problems, source eNB can initiate the mobility parameter modification negotiations process of cause value for " handover optimization " to target eNB.

Step 2, after target eNB is received the request message of source eNB, during the mobility parameter modification request in the message that judges whether to accept request, advised, also according to the mobility parameter currency of the cell-of-origin of carrying in the request message, the increment size that cell-of-origin and Target cell mobility parameter will be revised, and the matching that the information such as mobility parameter currency of Target cell oneself are carried out the new mobility parameter of two neighboring intervals detects: (specifically can add the value to be confirmed that the increment size that will revise draws according to the currency of cell-of-origin and Target cell mobility parameter if problem has been found in the matching detection, judge to revise the overlapping region Satisfying Matching Conditions whether on the mobility border of cell-of-origin, back and Target cell), then return mobility parameter modification failed message, carry cause value " detection of mobility parameter matching is not passed through " in the failed message, go back the mobility parameter currency of portability Target cell in addition, and/or the allowed band of the mobility parameter of Target cell; Pass through if matching detects, then continue next step by existing flow process;
The essence of this scheme is to increase matching to detect in existing modification negotiations process, and promptly the target side base station increases a matching again and detects after finishing present existing detection.
Step 3, after source eNB receives the failed message of target eNB, if carried cause value " detection of mobility parameter matching by " in the failed message, then to cause the reason of this mobility parameter modification negotiations process failure be that the new mobility parameter of two neighboring intervals does not match in expression.
Further, the mobility parameter described in the said method can be the threshold values (being the handover trigger parameter) that is used to trigger the parameter of switching, and when reaching this threshold values, cell initialization is to the switching set-up procedure of a specific adjacent area.
