Background technology
In time-division duplex (TDD-SCDMA) system, the 3GPP standard provides 3 incidents roughly the same frequently, is respectively 1G, 1H and 1I incident, and wherein, 1G represents that best cell changes; 1H represents that slot interfering signal of time sign indicating number power (ISCP) is lower than a definite thresholding; 1I represents that time slot ISCP is higher than a definite thresholding.
Network side is specified with the needed relevant parameter of incident frequently, when the user be in CELL_DCH (cell private channel) attitude and according to measure Control Parameter and measurement result monitor event criteria just can the trigger event report when satisfying.Network side is received event report, can carry out slow dynamic channel allocation, processes such as resource optimization and initiation switching.
With the incident evaluation process is as follows frequently:
(1) after subscriber equipment (UE) was set up Radio Link control (RRC) connection, network side sends measured control messages;
(2) UE measures one group of co-frequency cell according to the relevant parameter in the measurement control messages of network side transmission;
(3) UE assesses measurement result;
(4) if there is the sub-district to satisfy trigger condition, then UE joins this sub-district in the event variable, and transmission event report, wherein, event variable has write down the sub-district of satisfied report condition: trigger conditions is satisfied in this sub-district, (" timeto trigger ") satisfied trigger condition a period of time in the sub-district, this cell information not in the event variable;
(5) satisfy the leave event trigger condition when the sub-district, and the sub-district has been stored in the event variable, then UE will delete this cell information from event variable.

(1) for 1G, 1H or 1I incident, describe according to existing protocol, certain sub-district is satisfied threshold condition and is continued for some time (" time totrigger ") and just fills in measurement report only otherwise in event variable, can cause UE frequently to report same-frequency measure reporting like this.
For example, supposing to measure the sub-district has three of A, B, C, judges at first whether sub-district A satisfies trigger condition, if satisfy then startup " time to trigger " timer, judges then whether B satisfies.The timer of A then at first, this moment UE send out measurement report.The timer that trigger condition is satisfied in B or C sub-district then after, UE also will send out same-frequency measure reporting.If the measurement sub-district that satisfies condition is a lot, UE will constantly send measurement report in succession;
(2) for 1G, 1H or 1I incident, have only certain sub-district in event variable, just can not report by trigger event, UE can cause network side and UE side best cell information inconsistency like this because this sub-district does not report in event variable so change such as " best cell ";
(3) for 1H or 1I incident, describe according to existing protocol, measuring object is the ISCP value of certain a plurality of time slot in sub-district, and during incident assessment formula, only indicating needs sub-district time slot ISCP to be assessed to calculate, and does not clearly calculate with ISCP or which type of time slot of which time slot, at this moment both can be according to sub-district time slot mean value calculation, also can assess according to the current time slot that has maximum or minimum ISCP value, this uncertainty can have influence on the judging process and the result of incident;
(4) for the 1G incident, in the agreement not to the description of the initial value of event argument.Understanding can be initialized as sky according to agreement, also can be set to initial value by Serving cell.
At reporting in the correlation technique frequently, report not exclusively and the indeterminate uncertain problem of measurement result that causes of parameter initialization definition, effective solution is not proposed as yet at present.

C13, according to comparative result, fill in the information in the event argument;
If the ISCP value of C14 sub-district RSCP value or certain time slot satisfies trigger condition, write down this sub-district, start with frequency timer 1.(timer and the cell association that triggers this timer)
C15, all sub-districts of same measurement control messages are all assessed, satisfied trigger condition and just this sub-district is recorded in the sub-district of timer 1 association.
In above-mentioned steps D, timer 1 then back sends measurement report, and the associated cell of timer is filled in the report.
Leave trigger condition if satisfy the sub-district, and preserve cell information in the event variable and then this cell information is removed from variable.If UE receives when the corresponding common frequency measurement of the release of network side is measured control messages that UE can remove the event variable that should measure the control messages correspondence.
Optionally, above-mentioned steps C can also comprise:
Leave trigger condition if satisfy certain sub-district of C21, this sub-district is related with timer 1 simultaneously, then cancels this association.When last sub-district of timer 1 association is also deleted, then remove timer 1.
