Description

Configuration method and device for extended discontinuous reception and communication equipment

Technical Field

The application belongs to the technical field of communication, and particularly relates to a configuration method and device for extended discontinuous reception and communication equipment.

Background

In the related art, when a terminal is in an idle state, the terminal cannot be positioned. If positioning of an idle terminal is to be supported, it is required to solve how the idle sounding reference signal (Sounding Reference Signal, SRS) should be configured or how the idle positioning reference signal PRS should be measured in case of configuring the Core Network (CN) extended DRX cycle (extended DRX cycle, eDRX).

Furthermore, in view of power saving mechanism, it is possible to introduce a core network extended DRX cycle (extended DRX cycle, eDRX) or a RAN extended DRX cycle (extended DRX cycle, eDRX) of more than 10.24s in the inactive (inactive) state in the future. In this case, how the network side device confirms the DRX in which the terminal is located, and/or how to configure the sounding reference signal or positioning reference signal PRS window under DRX.

Based on the existing flow, the configuration information of CN eDRX/DRX is sent to the terminal by an access and mobility management function (Access and Mobility Management Function, AMF) when the terminal is registered; the base station is a relevant configuration obtained in a paging (paging) message, but the configuration information of the currently inactive SRS is carried by the base station in a radio resource control (Radio Resource Control, RRC) release (release) message. That is, when the base station configures the configuration information of the SRS, the base station may not be able to know the configuration information of the CN eDRX, so that the configuration of the SRS cannot be matched with the configuration information of the CN eDRX/DRX, and the power saving or positioning function of the terminal is affected. Furthermore, the location management function (Location Management Function, LMF) may recommend SRS configuration information to the base station, but the LMF does not know the configuration information of CN eDRX/DRX nor the configuration information of RAN eDRX/DRX, which may result in the recommended SRS configuration not matching the configuration information of DRX.

Fig. 1 shows a block diagram of a wireless communication system to which embodiments of the present application are applicable. The wireless communication system includes a terminal 11 and a network device 12. The terminal 11 may be a mobile phone, a tablet (Tablet Personal Computer), a Laptop (Laptop Computer) or a terminal-side Device called a notebook, a personal digital assistant (Personal Digital Assistant, PDA), a palm top, a netbook, an ultra-mobile personal Computer (ultra-mobile personal Computer, UMPC), a mobile internet appliance (Mobile Internet Device, MID), an augmented reality (augmented reality, AR)/Virtual Reality (VR) Device, a robot, a Wearable Device (weather Device), a vehicle-mounted Device (VUE), a pedestrian terminal (PUE), a smart home (home Device with a wireless communication function, such as a refrigerator, a television, a washing machine, or a furniture), a game machine, a personal Computer (personal Computer, PC), a teller machine, or a self-service machine, and the Wearable Device includes: intelligent wrist-watch, intelligent bracelet, intelligent earphone, intelligent glasses, intelligent ornament (intelligent bracelet, intelligent ring, intelligent necklace, intelligent anklet, intelligent foot chain etc.), intelligent wrist strap, intelligent clothing etc.. Note that, the specific type of the terminal 11 is not limited in the embodiment of the present application. The network-side device 12 may comprise an access network device or a core network device, wherein the access network device 12 may also be referred to as a radio access network device, a radio access network (Radio Access Network, RAN), a radio access network function or a radio access network element.

The core network device may include, but is not limited to, at least one of: core network nodes, core network functions, mobility management entities (Mobility Management Entity, MME), access mobility management functions (Access and Mobility Management Function, AMF), session management functions (Session Management Function, SMF), user plane functions (User Plane Function, UPF), policy control functions (Policy Control Function, PCF), policy and charging rules function units (Policy and Charging Rules Function, PCRF), edge application service discovery functions (Edge Application Server Discovery Function, EASDF), unified data management (Unified Data Management, UDM), unified data repository (Unified Data Repository, UDR), home subscriber server (Home Subscriber Server, HSS), centralized network configuration (Centralized network configuration, CNC), network storage functions (Network Repository Function, NRF), network opening functions (Network Exposure Function, NEF), local NEF (or L-NEF), binding support functions (Binding Support Function, BSF), application functions (Application Function, AF), location servers, location management functions (Location Management Function, LMF), evolved-based service mobile location center (Evolved Serving Mobile Location Center, E-SMLC), and the like. In the embodiment of the present application, only the core network device in the NR system is described as an example, and the specific type of the core network device is not limited.

Both LTE and NR introduce a DRX mechanism, meaning that DRX is discontinuous reception, and power saving of the UE is achieved by configuring DRX on (on) and off (off) times. As shown in fig. 2, the on duration is the period of DRX on, and if there is no scheduling, the UE enters an off period of one DRX cycle (cycle) after the on duration.

When the DRX is configured, a duration timer (onduration timer), a discontinuous reception inactivity timer (DRX-inactivity timer), a discontinuous reception forwarding timer (DRX-retransmission timer), a long discontinuous reception cycle start offset (longDRX-cycle offset), and other parameters are configured.

After the UE configures DRX, if the transmitted or received data fails to decode, the UE needs to enter an active time to monitor a control channel, and wait for retransmission scheduled by the network.

During the On Duration, if the UE is scheduled in a certain slot (slot) and receives data, it is likely to continue to be scheduled in the next few slots. Thus, starting or restarting the timer drx-InactivityTimer, UE every time the UE is scheduled to transmit data will be active until the timer expires.

For downlink data reception, after receiving downlink data transmission indicated by physical downlink control information (Physical downlink control channel, PDCCH) and feeding back hybrid automatic repeat request (Hybrid Automatic Repeat Request, HARQ) information, the UE starts a downlink backhaul Timer (HARQ RTT (Round Trip Time) Timer) for a corresponding HARQ process. If the HARQ RTT Timer is overtime and the data of the HARQ process is not successfully decoded, the UE starts a retransmission Timer (drx-retransmission Timer) and monitors the PDCCH to wait for transmission.

For uplink data transmission, after receiving the PDCCH to indicate uplink data transmission, the UE starts an uplink backhaul Timer HARQ RTT Timer for a corresponding HARQ process. After the HARQ RTT Timer is overtime, the UE starts a retransmission Timer (drx-ULRransmission Timer), enters an activated state to monitor the PDCCH, and waits for the transmission of network scheduling.

Under idle, the DRX cycle of conventional LTE is a maximum of 2.56s, and frequent wake-up consumes power of the UE. In order to reduce power consumption and extend standby time, eDRX mode is introduced. eDRX is Extended idle-mode DRX cycle, extended discontinuous reception. The terminal in this mode can receive downlink data only in a set Paging Time Window (PTW) during each eDRX cycle, and the rest of the time is in a sleep state without receiving the downlink data. The method has higher requirement on downlink service delay, and the platform of the Internet of things can buffer the message or immediately send the message according to whether the equipment is in a dormant state. Thereafter, the eDRX is also brought into an inactive state.

As shown in fig. 3, the terxcn may be several superframes (H-SFNs), terxcn=2, …,1024. One H-SFN corresponds to 1024 system frame numbers (System frame number, SFN), i.e. one superframe is equal to 10.24s, and the maximum period of the H-SFN is 1024H-SFNs, corresponding to 2.9127 hours.

After introducing the superframe, the following concepts are also introduced: PH paging Hyperframe, namely the super frame number where the paging message is located, unit H-SFN;

PTW paging Time Window, paging time window, SFN range in PH [ ptw_start, ptw_stop ];

PTW_start, the position of PTW start, unit SFN;

ptw_stop: the location where the PTW ends, unit SFN.

If the positioning of the idle terminal is to be supported, the following problems exist in the prior art:

(1) Based on the existing flow, the configuration information of CN eDRX/DRX is sent to the terminal by an access and mobility management function (Access and Mobility Management Function, AMF) when the terminal is registered; the base station is a relevant configuration obtained in a paging (paging) message, but the configuration information of the currently inactive SRS is carried by the base station in a radio resource control (Radio Resource Control, RRC) release (release) message. That is, when the base station configures the configuration information of the SRS, the base station may not be able to know the configuration information of the CN eDRX, so that the configuration of the SRS cannot be matched with the configuration information of the CN eDRX/DRX, and the power saving or positioning function of the terminal is affected. Furthermore, the location management function (Location Management Function, LMF) may recommend SRS configuration information to the base station, but the LMF does not know the configuration information of CN eDRX/DRX nor the configuration information of RAN eDRX/DRX, which may result in the recommended SRS configuration not matching the configuration information of DRX.

(2) The existing SRS coverage is described below, and may be understood as a coverage of a specific cell (cell-specific), but this may not be sufficient for an idle UE:

(a) Tracking Area (TA) verified (valid) areas;

TA timer, timeout is considered invalid;

exceeding the RSRP threshold is considered a failure;

(b) Cell reselection.

Aiming at the problem (1), how to interact with the affiliated base station in time is needed to be solved by the configuration information of the CN eDRX of the UE; for the problem (2), the configuration method of the SRS is needed to be solved in the TA or multi-cell area range, so as to be applicable to the idle state or the inactive state UE, thereby not frequently interrupting the eDRX state and affecting the power saving.

The configuration method of extended discontinuous reception provided in the embodiments of the present application is described in detail below with reference to the accompanying drawings through some embodiments and application scenarios thereof.

An embodiment of the present application provides a configuration method for extended discontinuous reception, as shown in fig. 4, including:

Wherein the first information comprises at least one of:

configuration information of at least one DRX of the plurality of DRX includes a period of DRX, a length of PTW, a start position of PTW, etc., and since the first communication device may not know ue_id_h and cannot calculate the start position of PTW, the first communication device may be notified of the specific start position of PTW;

In an alternative embodiment, the first terminal is configured with configuration information of a measurement window for measuring positioning reference signals in one of a plurality of DRX configurations, such as in RAN eDRX or CN eDRX >10.24 s; in another alternative embodiment, the first terminal first determines target DRX configuration information of the first terminal in a plurality of DRX configurations, the target DRX configuration is a DRX configuration used by the first terminal, and then determines configuration information of the measurement window for measuring the positioning reference signal in the target DRX.

In some embodiments, the first communication device obtaining the first information of the first terminal includes:

Alternatively, the first communication device, such as the LMF, may acquire the first auxiliary information from the first terminal, and may also acquire the first auxiliary information from the AMF.

In some embodiments, the first information acquired by the first communication device from the first terminal is included in first auxiliary information reported by the first terminal. In some cases, the base station receives first auxiliary information reported by the first terminal, which is used to help the base station determine information related to power saving or positioning of the first terminal, in an alternative embodiment, the first auxiliary information is embedded in a mobile originated location request (MO-LR request) or an event report (event report), that is, in the case that the first communication device is the base station, the first information is carried in a mobile originated location request (MO-LR request) or an event report (event report) message.

I.e. the first auxiliary information comprises the above-mentioned information in addition to the first information.

When the first auxiliary information sent by the first terminal includes configuration information of RAN eDRX with tendency greater than 10.24, a starting position H-SFN of the PTW may be calculated according to the following formula:

H-SFN modT _{eDRX_RAN} ＝(UE_ID_H mod T _{eDRX_RAN} ) (equation 1) or

H-SFN modT _{eDRX_CN} ＝(UE_ID_H modT _{eDRX_CN} ) (equation 2)
