Description

Determine method and the device of discontinuous receiving cycle starting point
Technical field
The present invention relates to the mobile communication technology field, particularly relate to method and the device of a kind of definite discontinuous reception (Discontinuous Reception is referred to as DRX) cycle starting point.
Background technology
At third generation partner program (3rd Generation Partnership Project, referred to as 3GPP) Long Term Evolution (Long Term Evolution, referred to as LTE) in the system, at Radio Resource control (Radio Resource Control, referred to as RRC) introduced DRX under the connected state, DRX refers to: terminal discontinuous reception descending scheduling and downlink data, when not needing downlink data receiving, terminal can be in dormancy (sleep) state, the radio frequency unit of terminal and other processing units can not worked, thereby reach the purpose of power saving.
Fig. 1 is the schematic diagram of the periodicity configuration of DRX in the prior art, as shown in Figure 1, each DRX is introduced into an of short duration continuous accepting state when beginning, be called and monitor the period (on duration), the monitoring period can continue one usually to several descending sub frames, monitoring the period, terminal is monitored physical down physical control channel (Physical Downlink Control Channel continuously, referred to as PDCCH), to determine whether the descending scheduling signaling for this terminal, and downlink data receiving accordingly, if terminal is received descending scheduling and downlink data during monitoring the period, will start other timer and carry out follow-up scheduling process; If but terminal does not receive descending scheduling and downlink data during monitoring the period, will enter dormancy (sleep) state, until again receiving scheduling signaling and downlink data of the monitoring period of next DRX original position.
In the prior art, not all business and all subscriber equipmenies (User Equipment, referred to as UE) all be fit to configuration DRX pattern, will be according to the characteristic of UE during configuration DRX parameter, because different business are to service quality (Quality of Service, referred to as QoS) require different, so need to link up with business in the DRX parameter configuration.Therefore, the DRX of different UE configurations may be different in the residential quarter, and the base station need to start monitoring period timer when UE is in activated state, the hardware load of consumption systems is wanted in the startup representative of timer, if do not limited, probably cause synchronization to put some UE and enter simultaneously the DRX state, surpass the disposal ability of base station.
In the LTE system, be the enable position (also can be called the DRX starting point) that decides the DRX of terminal according to the subframe sequence number, the DRX starting point is set in 3GPP 36.321 standards:
[(SFN*10)+subframe?number]modulo(longDRX-Cycle)＝drxStartOffset：
