Embodiment
In the correlation technique, for guaranteeing the quality of service of UE, but reduce again the power consumption of UE simultaneously as far as possible, base station (eNB) can be UE configuration discontinuous reception (Discontinuous Reception, referred to as DRX) parameter, UE only monitors Physical Downlink Control Channel (Physical Downlink Control CHannel, PDCCH) in according to the determined activationary time of DRX configuration parameter (active time), according to scheduling the transmission of data in activationary time of PDCCH.
Fig. 4 is the schematic diagram of a kind of DRX activationary time and inactive time.Wherein, 400 is a DRX cycle, and in this schematic diagram, under this DRX cycle, 401 is the DRX activationary time, and 402 is the inactive time of DRX, and UE only monitors PDCCH in 401 activationary times, according to scheduling the transmission of data in 401 activationary times of PDCCH.
In the correlation technique, DRX is divided into long DRX and short DRX, generally speaking, it is more discrete on the more sparse in other words time that long DRX can be used for the UE business datum, and UE is separated by and is just had the situation of data after long a period of time, and short DRX can be used for the UE data volume than comparatively dense or relatively concentrated on the time, and UE is separated by and is just had the situation of transfer of data after relatively shorter a period of time.Be the schematic diagram of a kind of long DRX and short DRX such as Fig. 5.
In the grand network of tradition, because therefore Zone switched long comparatively speaking between the macrocell, when UE enters Zone switched between the macrocell, even for UE has disposed long DRX, can not cause the travelling performance of UE sharply to descend.Yet, after introducing the LPN node in the grand network, when UE enters macrocell and LPN residential quarter Zone switched, relative Zone switched between the macrocell, macrocell and LPN residential quarter Zone switched comparatively speaking little a lot of only have Zone switched 1/3 large between traditional macrocell such as macrocell and LPN residential quarter Zone switched.And stipulate in the correlation technique, on the one hand, when UE measures the assessment adjacent area and satisfies the trigger condition of measurement report of network side configuration, if UE is in the inactive time of DRX, described measurement report can delayed delivery to network side, namely wait until when the DRX activationary time begins next time and send, thereby cause situation as shown in Figure 6, namely when UE is in the unactivated state of long DRX state (601. long DRX cycle), the trigger condition that measurement report is satisfied in the adjacent area triggers measurement report 602, but this measurement report is until 603 activationary time just is sent to network side, cause measurement report to postpone the length shown in 604, such as hundreds of ms, because macrocell and LPN residential quarter is Zone switched very little comparatively speaking, the measurement report of hundreds of ms probably causes the PDCCH signaling of follow-up UE reception serving BS scheduling measurement report transmission to be taken defeat by the LPN area interference time of delay, thereby finally cause serving BS in time to make handover decisions and cause UE that Radio Link Failure (Radio Link Failure, RLF) occurs.On the other hand, when if serving BS is made handover decisions, UE just in time is in the DRX unactivated state, serving BS can only be waited for when activationary time arrives next time and send switching command to UE, thereby cause situation as shown in Figure 7, namely when UE is in the unactivated state of long DRX state (701. long DRX cycle), handover decisions (702) is made in the base station, but switching command is until 703 activationary time just can send to UE, cause switching command to postpone the length shown in 704, such as hundreds of ms, because macrocell and LPN residential quarter is Zone switched very little comparatively speaking, the switching command transmission lag time of hundreds of ms probably causes follow-up UE reception switching command to be taken defeat by the LPN area interference, thereby finally causes handoff failure, and Radio Link Failure (RLF) occurs UE.
Therefore, realize that for real the deployment of low power nodes strengthens covering to be reached for traditional macrocell, strengthens network capacity, shares the purpose that macrocell is loaded, do not affect again simultaneously systematic function, need to seek the Enhancement Method to traditional mobile management, present embodiment provides the discontinuous receiving method in a kind of mobile management, specifically adopts following technical scheme:
