Description

[Technical Field]

[0001] The present disclosure relates to an information indication method and apparatus, a network device, a user equipment (UE), and a storage medium. [Background technology]

[0002] To save the power of the terminal, the network configures the UE with parameters such as discontinuous reception (DRX), eDRX, and power saving mode (PSM), thereby realizing power saving for the UE.

[0003] In a non-terrestrial network (NTN), when a satellite (e.g., a non-geostationary satellite) is moving, the service time provided by the satellite to each UE is limited. If the satellite orbital altitude is 600 km, the service time provided by one NTN cell to a terminal is limited due to the different cell coverage radii and the UE's moving speed. This means that the UE needs to perform handover and cell reselection after a certain time.

[0004] In the NTN-IOT (Internet of Things) network, discontinuous coverage scenarios exist, meaning that UEs in IoT-NTN networks may lack network coverage. When satellites within the NTN move, satellite cell coverage changes even if the UE is not moving, requiring a target cell search to complete synchronization. To reduce terminal power consumption, network devices configure the UE to use appropriate power-saving modes. For example, the UE must monitor paging messages when waking up from DRX / eDRX, or perform TAU when waking up from PSM. Due to discontinuous network coverage and rapid satellite movement, the UE must search for a network for each supported band, increasing UE power consumption. Currently, no technical proposals are available for this scenario. Summary of the Invention [Problem to be solved by the invention]

[0062] FIG. 3 is a schematic flowchart of an information indication method according to an exemplary embodiment. As shown in FIG. 3, the information indication method according to the embodiment of the present disclosure is applied to the user equipment side, and the information indication method according to the embodiment of the present disclosure includes the following processing steps:

[0063] In step 301, instruction information sent from a network device is received.

[0064] In an embodiment of the present disclosure, not performing cell search under the specified time condition includes at least one of: not monitoring a paging message under a specified time condition of the UE; not performing TAU under a specified time condition of the UE; and not performing cell search under a specified time condition of the UE and being in a dormant state, wherein not performing TAU under a specified time condition may be not performing TAU after a TAU timer of the UE expires.

[0065] The predetermined time condition includes being within a set time period or being before a set time, and the set time period or the set time period is determined by a core network device and / or an access network device.

[0066] In step 302, it is determined based on the instruction information that a cell search is not to be performed under a predetermined time condition.

[0067] In an embodiment of the present disclosure, not monitoring paging messages under the predetermined time condition includes at least one of: not monitoring paging messages in one or more POs in a DRX period when it is determined that DRX is configured for the UE; not monitoring paging messages within one or more PTWs, or not monitoring paging messages in one or more POs in at least one eDRX period within at least one PTW, when it is determined that eDRX is configured for the UE; and instructing the UE not to monitor paging messages during an operation period of an activation timer, or not to monitor paging messages in one or more POs in at least one eDRX period of the activation timer, when it is determined that PSM is configured for the UE.

[0068] In an embodiment of the present disclosure, the step of receiving the indication information transmitted from the network device includes: receiving the indication information indicating that the UE has entered an RRC disconnected state from an RRC connected state; case and receiving the indication information sent by the access network device via an RRC message.

[0069] Alternatively, the UE performs TAU and / or attach. case , and receives the instruction information sent from the core network device.

[0070] In addition to the processing flow of the above-mentioned embodiment, the information indication method according to the embodiment of the present disclosure further includes a step of determining, based on the UE indication information, to enter an RRC disconnected state under the time condition and not perform cell search.

[0071] For example, based on the received indication information sent from the network, the UE does not monitor a paging message, or the UE does not perform a TAU, or the UE does not perform a cell search and is in a dormant state.

[0072] In the embodiments of the present application, the UE may include an NB-IoT terminal, an eMTC terminal, etc., and in order to save power for such types of terminals, the network device can achieve the purpose of UE power saving by setting parameters such as DRX, eDRX, PSM, etc. in the UE.

[0073] Figure 4 is a schematic diagram of DRX shown in an exemplary embodiment. As shown in Figure 4, parameters related to DRX are configured by the gNB to the UE. The parameters related to DRX mainly include parameters such as the DRX period, and the UE determines to monitor network paging messages based on the DRX parameters.

[0074] In an embodiment of the present disclosure, to further save power of the UE, the base station further transmits instruction information to the UE via an RRC message, instructing the UE not to monitor paging messages in one or more POs of the DRX cycle. For example, if the base station predicts that the time when the current network cannot provide coverage to the UE is T1 and the next time when the UE can provide network coverage is T2, the base station instructs the UE not to monitor paging messages and / or not to perform cell search within T2-T1. If the instruction information includes time period information T2-T1 during which cell search is not performed, the base station instructs the UE not to monitor paging messages and / or not to perform cell search from time T1. The base station also instructs the UE not to monitor paging messages and / or not to perform cell search when the UE transitions from a connected state to a disconnected state. case The indication information may be sent via an RRC release-NB message or via an RRCEarlyDataComplete-NB message. After receiving the indication information, the UE does not monitor paging information in DRX mode.

[0075] FIG. 5 is a schematic diagram of eDRX according to an exemplary embodiment. As shown in FIG. 5, in each eDRX cycle, the UE can receive downlink data only within a configured paging time window (PTW). The UE is in a dormant state and does not receive downlink data for the rest of the time. The eDRX cycle ranges from 20.48 seconds to 2.92 hours. Each eDRX cycle includes one PTW. The UE monitors the paging channel within the PTW according to the DRX cycle (the DRX cycle is short, the UE is not dormant, and it is considered to be always reachable) to receive downlink data, and the UE is in a dormant state for the rest of the time.

[0076] In the eDRX parameters, the core network device and the UE negotiate the parameters of the eDRX period (T eDRX,H) and the PTW window length.

[0077] The core network device configures the eDRX parameters for the UE while the UE is attaching to the network or during TAU. The core network device may also transmit the eDRX parameters to the gNB via a paging message on the S1 interface, i.e., when the core network device starts paging the UE, it may also transmit the eDRX parameters to the gNB. In an embodiment of the present disclosure, when the core network device needs to transmit the indication information to the UE, the time to transmit the indication information is T3, the deadline for the network to provide coverage to the UE is T4, and the next time the network can cover the UE is T5, if the core network device enters the RRC disconnected state before time T4, the core network device instructs the UE not to perform cell search within a time period T5-T4, and the indication information includes an instruction not to perform cell search. When the core network device configures the eDRX parameters for the UE, it transmits the indication information to the UE. After the UE receives the eDRX parameters and the instruction information, it analyzes the time stage information T5-T4 from the instruction information. In eDRX, if the UE enters the RRC disconnected state before time T4, it will enter the dormant state from time T4 without performing cell search or monitoring paging messages, i.e., the UE will not monitor paging messages within one or more PTWs.

[0078] 6 and 7 are schematic diagrams of PSM according to an exemplary embodiment. As shown in FIGS. 6 and 7, PSM is implemented to further reduce power consumption. In PSM, downlink data is unavailable and the UE is in a sleep state. In this case, there are two ways for the UE to wake up: first, when the UE needs to transmit uplink data, and second, when the TAU timer expires. Upon entering PSM, the UE no longer receives paging messages and downlink data. Here, T3321 and T3412 are two timers that are configured in the UE by a core network device. Typically, when the UE attaches to a network and performs TAU, the core network device configures the PSM parameters and / or eDRX parameters, as well as the duration parameters of T3321 and T3412, in the UE.

[0079] In the case of eDRX, the UE is in a dormant state except for PTW, at which time the UE does not receive downlink data and does not perform any measurements on the serving cell and neighboring cells; when the UE enters PSM state, it does not receive downlink data and does not perform any measurements on the serving cell and neighboring cells.

[0080] In an embodiment of the present disclosure, a core network device configures PSM parameters and indication information in a UE when the UE is attaching to a network or during a TAU. When the core network device needs to send the indication information to the UE, the time at which the indication information is sent is T3, the deadline for the network to provide coverage to the UE is T4, and the next time the network can cover the UE is T5. If the core network device enters an RRC disconnected state before time T4, the core network device instructs the UE not to perform a cell search within a time period T5-T4, and the indication information includes an instruction not to perform a cell search. When the core network device configures eDRX parameters in the UE, the core network device sends the indication information to the UE. After the UE receives the eDRX parameters and the instruction information, it analyzes the time stage information T5-T4 from the instruction information, and instructs the UE in the PSM that if the UE enters the RRC disconnected state before time T4, from time T4, the UE will enter a dormant state without performing cell search or monitoring paging messages, and in the eDRX mode, not to monitor paging messages in one or more POs within at least one eDRX period of the activation timer operation period.

[0081] FIG. 8 is a schematic diagram of the structure of an information indication device shown in an exemplary embodiment.
