The network elements or network functions involved in the embodiments of the present disclosure may be implemented by independent hardware devices or by software in the hardware devices, and this is not limited in the embodiments of the present disclosure.

The user equipment (UE) takes into account both low power consumption and services with certain requirements on latency. In each enhanced discontinuous reception (eDRX) cycle, there is a paging time window (PTW). During the PTW, the terminal device can monitor the paging channel according to the discontinuous reception (DRX) cycle to receive downlink data. The DRX cycle time is short, so it can be considered that the terminal device does not sleep and is always reachable.

That is to say, the terminal device can receive downlink data only within the set PTW. The terminal device is in sleep mode and does not receive downlink data during the rest of the time. This mode can achieve a balance between downlink service latency and power consumption, such as remotely shutting down gas services.

Figure 1 is an example schematic diagram of an eDRX mode provided by an embodiment of the present disclosure. As shown in Figure 1, the eDRX mode can assume that the terminal device is reachable at any time, but the delay is large, and the delay depends on the eDRX cycle configuration, which can strike a balance between low power consumption and delay.

In the eDRX mode feature, the following parameters need to be negotiated between the UE and the core network:

T _eDRX,H : eDRX period;

L: PTW window length.

FIG2 is a schematic diagram of an interaction between a UE and a core network for negotiation provided by an embodiment of the present disclosure. As shown in FIG2, first, the base station (Evolved Node B, eNB) sends a system information block (System Information Block, SIB) to the terminal device, wherein the SIB includes allowed eDRX (eDRX allowed), cell-specific DRX (Cell-specific DRX) and hyperframe (Hyper SFN) information. Then, the terminal device sends an additional (ATTACH) or tracking area update (Tracking Area Updating, TAU) information to the network node (Mobility Management Entity, MME), wherein the additional or tracking area update information includes the DRX of a specific terminal device (UE-specific DRX) and the preferred eDRX (preferable eDRX). Secondly, the network node sends an eDRX configuration to the terminal device. Then, the network node uses the eDRX configuration to page the base station. Finally, the base station pages the terminal device.

Therefore, as shown in Figure 2, the negotiation process between the UE and the core network is carried out through Network Attached Storage (NAS) messages, which is completely transparent to the base station.

In addition, the inactive state is introduced in the new radio (NR). At this time, the UE not only needs to receive paging from the core network, but also needs to receive paging from the radio access network (RAN) (from the core network, the UE is in a connected state). According to the relevant conclusions, the RAN determines and configures eDRX through the radio resource control (RRC) for invalid RRC (RRC_INACTIVE), that is, the RAN will allocate a shorter inactive eDRX cycle _TeDRX,RAN to the terminal device, among which the necessity and details of coordination with the core network (CN) need to be studied further.

At the same time, in the relevant conclusion, the length of the PTW is configured by the RAN for RAN paging, and the RAN PTW length can be different from the CN PTW length. When RAN and CN paging overlap in the same PH, the PTW starting position is the same. Among them, how to calculate the PTW starting position so that it is the same for RAN and CN PTW needs further study.

That is to say, RAN will allocate a PTW window length to the terminal device. At that time, the starting point of the PTW window is the same as that of the PTW window allocated by CN, but the length is not yet defined. It can be considered that CN allocates the first eDRX parameter to the terminal, that is, the idle mode eDRX parameter or the extended DRX for RAN paging; the base station allocates the second eDRX parameter to the terminal device, that is, the non-active mode eDRX parameter or the extended DRX for RAN paging.

For a terminal device, the base station usually displays an indication of whether idle eDRX (first flag) or inactive eDRX (second flag) is supported, and the second flag can only be configured when the first flag is configured or enabled. The indication is as follows:

Allow idle eDRX (eDRX-AllowedIdle): The presence of this field indicates that the use of extended DRX for CN paging monitoring is allowed in the unit of the UE in idle RRC (RRC_IDLE) or inactive RRC (RRC_INACTIVE). If eDRX-AllowIdle does not exist, the UE shall stop using extended DRX for CN paging monitoring in RRC_IDLE or RRC_INACTIVE;

eDRX-AllowedInactive: The presence of this field indicates that the use of extended DRX for RAN paging is allowed in the unit of the UE in RRC_INACTIVE. If eDRX-AllowedInactive is not present, the UE shall stop using extended DRX for RAN paging in RRC_INACTIVE.

For the terminal device, the UE can be configured with an eDRX cycle _{TeDRX, CN} and/or _{TeDRX, RAN} configuration by the upper layer and/or RRC. If the UE is configured with eDRX parameters by the upper layer, and eDRX-AlloweIdle is carried and sent in SIB1, the UE can use eDRX to monitor CN paging in RRC_IDLE or RRC_INACTIVE state. If the UE is configured as eDRX by the RAN, and eDRX-AllowedInactive is carried and sent in SIB1, the UE runs in eDRX to monitor RAN paging in RRC_INACTIVE state.

Whether the terminal device can use the first eDRX parameter (eDRX for CN paging) depends on whether the network has configured the parameter for it and the first flag is enabled. Whether the terminal device can use the second eDRX parameter (DRX for RAN paging) depends on whether the network has configured the parameter for it and the second flag is enabled. The network enabling the first flag or the second flag is that the network carries and sends the first flag or the second flag in SIB1;

Among them, since whether the terminal device can use the first eDRX parameter (eDRX for CN paging) depends on whether the network has configured the parameter for it and the first identifier is enabled, the first identifier is the first identifier corresponding to the first eDRX parameter, referred to as the first identifier. Whether the terminal device can use the second eDRX parameter (DRX for RAN paging) depends on whether the network has configured the parameter for it and the second identifier is enabled, the second identifier is the second identifier corresponding to the second eDRX parameter, referred to as the second identifier.

It is easy to understand that when an inactive user, when the network configures the first eDRX parameter and the second eDRX parameter at the same time, if the current cell does not configure the second identifier, the second eDRX parameter cannot be used, but if the cell configures the first identifier, the first eDRX parameter can still be used. However, there is no relevant protocol describing this scenario, that is, there is a lack of relevant protocols for determining the paging cycle.

A paging cycle determination method, apparatus, device, and storage medium provided by an embodiment of the present disclosure are described in detail below with reference to the accompanying drawings.

The network enabling the first identifier or the second identifier is that the network carries and sends the first identifier or the second identifier in SIB1.
