S101:UE calculates the radio frames at Rx Burst and place on the opportunity of measurement, and wherein, Rx Burst occurs in different radio frames opportunity from measurement.
In step S101, the parameter that user equipment (UE) is measured Pattern according to discontinuous reception modes DRX Pattern and the measurement pattern of network equipment configuration, calculate to receive the radio frames at burst Rx Burst and place on the opportunity of measurement, wherein, receive burst Rx Burst and occur in different radio frames opportunity from measurement.
For example, the parameter of network equipment configuration discontinuous reception modes DRX Pattern and measurement pattern measurement Pattern comprises the following steps:
The reception burst Rx Burst that DRX Pattern determines sends the radio frames of information to UE, corresponding system frame number SFN is eligible: (SFN-H-RNTI) mod (DRX_cycle)＜Rx_burst, wherein, H-RNTI is the specific deviant Offset of UE;
Measuring the radio frames that Pattern determines is the measurement opportunity of described UE, and described measurement opportunity, corresponding system frame number SFN was eligible:
SFN+Offset_M＝H-RNTI mod(M_REP)+n*M_REP (3)
Wherein, H-RNTI is the specific deviant Offset of UE, the time offset of deviant Offset_M for increasing.
Formula (3) increases time migration Offset_M on the basis of formula (2), Offset_M is the plus or minus integer, and other parameters are according to the definition of existing protocol.the value of Offset_M can be notified UE and/or NodeB by the mode of predefine or high-level signaling, described predefined mode, get certain fixed value as prior agreement Offset_M, the mode of described high-level signaling notice, as the value of Offset_M is broadcasted in system message, perhaps the extra information unit IE that increases indicates the value of described Offset_M to UE in the RRC signaling, and/or by NBAP (NodeB ApplicationProtocol, the NodeB application protocol) in signaling, the extra information unit IE that increases indicates the value of described Offset_M to NodeB.
