Description
Technical field
The present invention relates to communication technical field, relate in particular to a kind of method and apparatus of event-triggered reporting.
Background technology
Existing cell mobile communication systems such as 3G (3
RdGeneration, 3-G (Generation Three mobile communication system)) data rate that provides has very big difference at center of housing estate and cell edge, and this has not only influenced the capacity of whole system, and the service quality that the user is obtained in different positions has very big fluctuation.Compare present CDMA (Code Division Multiple Access, code division multiple access inserts) system, based on OFDM (Orthogonal Frequency Division Multiplexing, OFDM) system of broadband wireless communication of technology will face more serious problem of inter-cell interference owing to there has not been cdma system minizone randomization effect preferably.Therefore, the new generation broadband wireless communication system of researching and developing at present all will improve cell-edge performance as one of main indexes, and propose much the special technology solution at cell edge UE (UserEquipment, user terminal).
ICI (Inter-cell Interference, presence of intercell interference) is an intrinsic problem of cell mobile communication systems, and traditional solution is to adopt channeling, and multiplexing coefficient has only specific several selections, as 1,3,7 etc.Multiplexing coefficient is 1 to represent that promptly neighbor cell all uses identical frequency resource, if two neighbor cells use identical frequency spectrum resource in their joint portion, then can produce stronger ICI.Higher multiplexing coefficient (3 or 7) can suppress ICI effectively, but spectrum efficiency will be reduced to 1/3 or 1/7.
Study ICI inhibition technology at present and mainly comprising interference randomization, interference coordination, interference eliminated etc.Interference coordination comprises " soft-frequency reuse " or " partial frequency multiplexing ", and this method is distinguished the user at center of housing estate and edge, distributes different frequency resources and power resource so that ICI is eliminated.Consider UE (the User Equipment of center of housing estate, user terminal) different with edge UE to the interference of adjacent sub-district, edge UE performance becomes lower because there being bigger presence of intercell interference, therefore for center of housing estate UE and edge UE, no matter be scheduling strategy or interference coordination, all need different strategies.Therefore the relative position of UE need be known in the base station, and promptly to be in center of housing estate still be that cell edge is if cell edge needs also to know that UE is nearer apart from which adjacent sub-district to UE.
In order to determine whether UE is in cell edge, has proposed reporting event mechanism in LTE (Long Term Evolution, the Long Term Evolution) system, when UE satisfies the trigger condition of this incident, just carries out reporting of measurement event to network side.During measurement result that network side reports according to this measurement event of receiving, determine whether whether UE is positioned at the edge, and adjacent, thereby this UE is taked the scheduling strategy of edge UE with which sub-district.
The inventor finds that there is following problem in prior art in realizing process of the present invention: can't be by responding with the interference scheduling of assurance to UE on the measurement event.

Rattling near a zone for fear of UE reports, the amount of hysteresis that has been each event definition in the LTE system, and based on amount of hysteresis and event definition entry condition and leave condition.Entry condition triggers UE and carries out reporting of incident, and the condition of leaving then is used for the satisfied sub-district of leaving condition of candidate cell is deleted from report list.Entry condition and leave condition and formed a zone.Because the measurement reported event of definition is to report for the switching of supporting UE at present, therefore for switching, whether the signal level that only need know neighbor cell well boundary, if well boundary, UE just needs to send measurement report so, tell the signal level of the adjacent sub-district of network to be better than a boundary, network side can be thought of as UE in view of the above and initiate to switch.
And for ICIC (ICI Coordination, Inter-Cell Interference Coordination) measurement reports, need report a zone, the measurement report that is to say ICIC reports when needing the measuring-signal amount of UE in adjacent sub-district to reach certain threshold value, when the measuring-signal amount of adjacent sub-district was lower than certain threshold value, ICIC also needed to report.Its reason is, the measurement of ICIC reports the signal level that not only needs adjacent sub-district to be better than the information of boundary, because may need to start interference coordination this moment, and when the signal level of adjacent sub-district has been lower than a boundary, also need to tell network side because network side in view of the above the end-of-message interference coordination operation or adjust the strategy of interference coordination.
Owing to can only report a boundary value for a measurement event at present, when target only no longer satisfies incident, not report.Therefore in order to obtain the reported result of 2 boundary values, just need 2 incidents.And for the specific zone that reports is set, the parameter setting between 2 incidents needs correlation.Except correlation, define new incident, need the definition set of parameter corresponding with this incident.Therefore,, then can't report a zone of 2 boundaries compositions, just can't satisfy the area reporting of ICIC needs if do not define new incident; If define new incident, then need a new cover incident corresponding parameters, and need consider the applied in any combination between the different event during actual the use, this can bring the complexity of agreement and the complexity of application.
