In the present embodiment, the DRX timer is T321, wherein, T321 represents the timing length of DRX timer, if T321＞measurement thresholding or T321＞=measurement thresholding, then T321 cut-off (expiring) is front, and UE is on default measurement opportunity, carry out the different system of alien frequencies adjacent cell measurement, definite method on described measurement opportunity is seen the description among the embodiment one;
Such as, T321 is 800ms, the measurement thresholding is 400ms, and T321＞measurement thresholding, T321 run duration so, UE can carry out the different system of alien frequencies adjacent cell measurement.
In addition, it should be noted that: in order to reduce losing of data, optionally comprise, if T321＞measurement thresholding or T321＞=measurement thresholding, then T321 cut-off (expiring) is front, and base station NodeB does not send data to this UE in described measurement opportunity.
2, the running time of DRX timer is more than or equal to measuring thresholding.

In the present embodiment, if satisfy default measurement during opportunity at current system frame or radio frame number SFN, frequency priority is higher than current service frequency priority under the adjacent cell, then UE carries out and can carry out alien frequencies different system adjacent cell measurement or only to measure adjacent cell on the described high priority frequency, and definite method on described measurement opportunity is seen the description among the embodiment one;
Wherein, frequency priority is that RNC sends to UE by special-purpose or public RRC message under Serving cell and/or the adjacent cell, sends to UE such as system message or UTRAM MOBILITY INFORMATION; Frequency priority is that RNC sends to NodeB by signaling or FP under Serving cell and/or the adjacent cell, such as sending to NodeB by PHYSICAL SHARED CHANNEL RECONFIGURATION REQUEST or HS-DSCH FRAME TYPE2.
In addition, it should be noted that: in order to reduce losing of data, optionally comprise, if frequency priority is higher than current service frequency priority under the adjacent cell, then T321 cut-off (expiring) is front, and base station NodeB does not send data to this UE in described measurement opportunity.
5, satisfy default measurement during opportunity at current system frame or radio frame number SFN, UE Serving cell quality is less than or equal to default quality threshold.
The evaluation index of Serving cell quality described here can be among received signal code power (Received Signal Code Power, RSCP), signal to noise ratio Ec/No, the path loss pathloss at least one.
In the present embodiment, if satisfy default measurement during opportunity at current system frame or radio frame number SFN, UE Serving cell quality is less than or equal to default quality threshold, and then UE carries out the different system of alien frequencies adjacent cell measurement, and definite method on described measurement opportunity is seen the description among the embodiment one;
In addition, it should be noted that: in order to reduce losing of data, optionally comprise, if UE Serving cell quality is lower than default quality threshold, then T321 cut-off (expiring) is front, and base station NodeB does not send data to this UE in described measurement opportunity.

In the present embodiment, after UE discharged common E-DCH resource, on default measurement opportunity, the number of times that T321 is restarted was more than or equal to measuring thresholding, and then UE carries out the different system of alien frequencies adjacent cell measurement opportunity in described measurement.Such as, when UE discharges common E-DCH, start T321, T321 cut-off (expiring) is front, and UE receives the HS-DSCH data, then restarts T321, on described measurement opportunity, T321 is restarted at least measures the thresholding number of times, and then UE carries out the different system of alien frequencies adjacent cell measurement opportunity in described measurement.Be that 2, UE carries out the different system of alien frequencies adjacent cell measurement in described measurement opportunity such as measuring the thresholding number of times, concrete example as shown in Figure 3.
In addition, it should be noted that: in order to reduce losing of data, optionally comprise, after UE discharged common E-DCH resource, on described measurement opportunity, T321 is restarted at least measured the thresholding number of times, and then NodeB does not send data to this UE in described measurement opportunity.
Further need to prove: appoint the combination of at least two conditions in the condition 1 to 6, also belong to the condition of carrying out the different system of alien frequencies adjacent cell measurement.Such as, if the timing of DRX timer length＞=measurement thresholding, and DRX timer cut-off (satisfying) is front does not take common E-DCH resource at default adjacent cell measurement this UE on opportunity of the different system of alien frequencies, then the different system of UE execution alien frequencies adjacent cell; For another example, the DRX timer is operating measurement thresholding time span at least, and UE do not take common E-DCH resource at default alien frequencies isosystem measurement opportunity, and then UE carries out the different system of alien frequencies adjacent cell measurement.
In S205, detect current system frame or radio frame number SFN and whether satisfy default measurement opportunity, if so, then carry out the different system of alien frequencies adjacent cell measurement.(do not advise writing like this, the behavior of suggestion UE side and NodeB side limits separately)
Concrete 202,203 and 205, see the description among the embodiment one for details, do not repeat them here.
