Abstract

Disclosed are a method and an eNB (evoluted Node B) for adjusting DRX (discontinuous reception) parameters in a long term evolution system. The method is applied in an evolution-type base station, and includes aiming at each user equipment (UE), executing the following operations: collecting all historical service data conditions of the UE in some past time; calculating adjusting values to current noncontinuous receiving (DRX) parameters according to collected historical service data; adjusting the DRX parameters currently used by the UE according to the adjusting values. By adopting the method, the eNB can predict near-term service characteristics of the UE, calculate the DRX parameters suitable for service types of the UE and adjust the DRX parameters of different UE on the basis of monitored historical service data of the UE so as to achieve the objectives of electricity saving and good QoS (quality of service) guarantee of the UE, so that better user experience is acquired.

Description

In long evolving system, carry out method and the eNB of DRX parameter adjustment

Technical field

The present invention relates to 3GPP (The 3rd Generation Partnership Project, third generation partner program) Long Term Evolution (the Long Term Evolution proposing, referred to as LTE) field, relate in particular to a kind of DRX (Discontinuous Reception that carries out in LTE system, discontinuous reception) method of parameter adjustment and eNB (evolved Node B, evolved base station).

Background technology

The broadband wireless high speed data transfer that LTE provides adopts the short frame design of 1ms, mean UE (User Equipment, subscriber equipment) need every frame to intercept Physical Downlink Control Channel (Physical Downlink Control Channel, referred to as PDCCH), the electric weight of consumption UE that therefore can be sharply.In LTE, the mechanism of DRX has been proposed, object is to allow not have the UE of transfer of data to turn off wireless receiver according to the cycle of agreement regulation, thereby reaches the object of power saving.

The DRX mechanism of above-mentioned protocol description is faced with UE power saving amplitude and good QoS (Quality of Service, service quality) considering between guaranteeing.Particularly, if turn off the overlong time of wireless receiver, the response speed of business is slower, may affect user and experience; If it is too short to turn off the time of wireless receiver, will affect the power saving amplitude of UE, be unfavorable for the flying power of UE.

The leading LTE agreement of 3GPP is described the DRX mechanism for UE under RRC_CONNECTED (Radio Resource control connection) state in detail.RRC (Radio Resource Control, radio resource control) can control UE by configuration and whether adopt DRX, thereby control C-RNTI (the Cell Radio Network Temporary Identifier whether UE intercepts PDCCH, Cell Radio Network Temporary Identifier/Identity, Cell-RNTI), TPC-PUCCH-RNTI (transmitting power control-Physical Uplink Control Channel-Radio Network Temporary Identifier), TPC-PUSCH-RNTI (transmitting power control-Physical Uplink Shared Channel-Radio Network Temporary Identifier) and Semi-Persistent Scheduling C-RNTI (semi-persistent scheduling C-RNTI).

If the UE in RRC_CONNECTED state has configured DRX and has enabled, UE does not need PDCCH to intercept during the appointment of DRX parameter, Physical Downlink Shared Channel (Physical Downlink Shared Channel, referred to as PDSCH) and Physical Uplink Shared Channel (Physical Uplink Shared Channel, referred to as PUSCH) there is no transfer of data, UE is at this time in SLEEP (dormancy) state.And if during the appointment of DRX parameter, need to intercept PDCCH, at this time UE is in ON (work) state.Whether if configure DRX, do not enable, UE need to intercept PDCCH always, always in ON state, to determine on PDSCH or PUSCH, have data to need transmission.

DRX is divided into two kinds of long period (longDRX-Cycle) and short periods (shortDRX-Cycle), and wherein acquiescence does not enable the short period.If UE configuration DRX enables, at DRX, in the short period, during ON state, open RF modem (rf-mode), to intercept PDCCH.When detecting PDCCH indication PUSCH or PDSCH while having data to be transmitted, eNB for this reason UE starts a drx-InactivityTimer (the static timer of DRX), so that this UE continues to intercept to PDCCH during this period.If drx-InactivityTimer is overtime, UE enters SLEEP state.In order to increase the reaction sensitivity of UE transfer of data, if UE is not in listening on PUSCH and PDSCH and have data to be transmitted during ON state, UE enters DRX long period.

Each UE depends on the setting of the following parameter of DRX: onDurationTimer (duration timer), drx-InactivityTimer in SLEEP state or ON state, drx-RetransmissionTimer (DRX retransmission timer), longDRX-Cycle (DRX long period), drxStartOffset (DRX start offset amount), also have optional drxShortCycleTimer (DRX short cycle timer) and shortDRX-Cycle (DRX short period).

In above-mentioned DRX mechanism, the parameter of using can be configured and reprovision by RRC.Therefore very important decision-making of RRC is exactly to configure above-mentioned many DRX parameters, to make UE make balance aspect power saving and QoS experience.
