Description

Method, system, electronic device and storage medium for monitoring paging message

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method, a system, an electronic device, and a storage medium for monitoring a paging message.

Background

In a New Radio (NR) system of The Fifth-Generation mobile communications (5G), when a User Equipment (User Equipment, UE) transmits uplink data or downlink data in a Radio Resource Control (RRC) idle state (idle state), The User Equipment needs to switch from The idle state to a connected state (connected state). At present, there is a way that a UE can directly send a small amount of Uplink data in an idle state, that is, a network configures a dedicated and periodic Uplink pre-configured resource (PUR) and a corresponding Downlink search space window for the UE, so that the UE can send the Uplink data through the PUR and can monitor a Physical Downlink Control Channel (PDCCH) through the Downlink search space window to receive the Downlink data.

Considering that the propagation delay between the UE and the satellite is too large, after the UE sends the uplink data, it needs to wait for a period of time (i.e. Round trip time, RTT) before receiving the feedback (HARQ-ACK) sent by the network.

When a Predetermined Uplink Resource (PUR) transmission mechanism is applied to an NTN (Non Terrestrial/satellite communication) scenario, after the UE sends Uplink data using the PUR, it needs to wait for a period of time before receiving feedback (i.e., there is at least a time interval between the PUR and the PUR SS Window that is not less than RTT) issued by the Network end, and when there is a PO (Paging occasion) between the PUR and the PUR SS Window, according to the existing mechanism, after the UE sends Uplink data using the PUR, it needs to wake up to monitor the PO between the PUR and the PUR SS Window before monitoring the PUR SS Window, and there is a certain energy consumption overhead, the same similar problems exist when the time interval is not less than RTT between Msg1 and Msg2, Msg3 and Msg4(4-Step RACH, four-Step random access procedure) and MsgA and MsgB (2-Step RACH, two-Step random access procedure).

Detailed Description

The invention is further illustrated by the following examples, which are not intended to limit the scope of the invention.

Example 1

The method for monitoring the paging message of the embodiment is applied to the user equipment and applied to the NTN scenario.

In the NR system, a UE in idle/inactive state wants to send uplink/downlink data, and needs to enter a connected state through a random access procedure before sending the uplink/downlink data. The data transmission mechanism under idle/inactive causes RRC signaling overhead and UE energy consumption, and also causes data transmission delay.

In order to reduce RRC signaling overhead and UE energy consumption caused by UE sending uplink data in idle state, an Early Data Transmission (EDT) mechanism is introduced in narrowband internet of things (NB-IOT)/enhanced machine type communication (eMTC). The essence of the transmission mechanism is that the UE uses the third message (Msg3) to carry uplink data to achieve the purpose of uplink data transmission during the process of initiating random access, so as to prevent the UE from entering a connected state. Aiming at uplink data transmission in an idle state, the method effectively reduces the overhead of RRC signaling and the energy consumption of the UE, and simultaneously reduces the energy consumption of the UE. However, due to the limited number of bits Msg3 can carry, this approach can only upload a few small upstream packets.

In order to enable the UE to transmit a larger data packet in an idle state, a conventional NB-IOT/eMTC mechanism is that a network configures dedicated periodic uplink preconfigured resources and corresponding downlink search space windows PUR SS Window for the UE, and the UE may send uplink data through the uplink preconfigured resources and then receive an ACK/fallback indication or retransmit scheduling information through the corresponding downlink search space windows. The fallback indication is used to indicate the UE to fall back to the RACH/EDT mode for data transmission, and the network may control the validity of the PUR resource through the fallback indication, that is, when uplink resources of the network are short, the network may indicate the UE to fall back to the RACH/EDT mode for data transmission. The UE can directly send uplink data on the uplink pre-configured resource, so that the UE is prevented from initiating a random access and entering a connected state process. The UE can transmit data by using the PUR only when the TA (Timing advance) is valid (i.e., the uplink synchronization is valid).

In addition, in the PUR transmission mechanism, when the UE uses the PUR to send uplink data and the uplink data is correctly received by the base station, the network may consider the UE as a temporarily connected UE, and if the network has indication information (paging/system information update indication) to be sent to the UE, the network may notify the UE through downlink data or signaling (instead of paging information), that is, if the UE uses the PUR to send the uplink data and is correctly received by the base station, the UE may obtain the indication information of the network by monitoring the corresponding PUR SS Window (if the network has indication information to be sent to the UE).

In NTN satellite communications, the channel propagation delay is relatively large due to the high altitude of the satellite (e.g., geostationary satellite: 35786 Km). For example, in a geostationary satellite scenario, the round trip propagation delay RTT between the UE and the satellite is 270.73 ms. Due to the large propagation delay, there is a large time interval (i.e. one RTT of time) between the PUR and its corresponding HARQ-ACK reception.

As shown in fig. 1, the method for monitoring a paging message in this embodiment includes:

s101, sending uplink data by adopting an uplink pre-configuration resource;

s102, determining that the paging time between the uplink pre-configured resource and the downlink search space window is not monitored, and monitoring a physical downlink control channel in the downlink search space window to obtain a paging message fed back by a network end according to uplink data.

The first set duration is configured by adopting RRC signaling or system information.

In this embodiment, after the UE sends the uplink data by using the PUR, the UE does not monitor the PO between the PUR and the PUR SS Window, but directly monitors the physical downlink control channel in the downlink search space Window, and at this time, the user equipment does not need to keep a monitoring state after sending the uplink data, thereby effectively saving power consumption caused by monitoring the PO and saving energy consumption overhead of the UE.

Example 2

The method for monitoring the paging message in this embodiment is a further improvement ofembodiment 1, and specifically:

as shown in fig. 2, step S101 is followed by:

s103, monitoring a first paging moment before the downlink search space window and with a time interval less than a first set time length to acquire a paging message.

Step S101 is preceded by:

a first indication parameter of a monitoring mode is configured in advance;

the first monitoring mode correspondingly indicates to monitor the paging time between the uplink pre-configured resource and the downlink search space window;

the second monitoring mode correspondingly indicates not to monitor the paging time between the uplink preconfigured resource and the downlink search space window, that is, step S102 is executed at this time.

The first indication parameter is configured by RRC signaling or system information, that is, whether a monitoring mode of the paging time PO is needed is determined by the indication parameter.

The monitoring method of the embodiment further includes:

determining a first target monitoring mode according to a first preset indication parameter;

the first target monitoring mode is a first monitoring mode or a second monitoring mode. Or the like, or, alternatively,

in addition, when the eDRX scene is in, the first monitoring mode is determined to be executed, and when the eDRX scene is not in, the second monitoring mode is determined to be executed.

The Paging message (Paging message) functions include: (1) sending a call request to the UE in an RRC _ IDLE state; (2) informing the UE in the RRC _ IDLE/INACTIVE and RRC _ CONNECTED states that the system information is changed; (3) the method comprises the following steps of (1) earthquake and tsunami notification, indicating UE to start receiving ETWS (earthquake and tsunami warning system) primary notification and/or ETWS secondary notification; the UE is instructed to start receiving CMAS notifications.

If a terminal (i.e. user equipment) is paged or system information is updated or an earthquake and tsunami occurs, a base station (i.e. a network side) firstly sends a wake-up signal, and after detecting the wake-up signal, the terminal monitors a paging PDCCH (physical downlink control channel) and receives a paging message, otherwise, the terminal keeps a sleep state all the time to achieve the purpose of saving power.

In an eDRX scenario, in each eDRX cycle, there is a paging Time window PTW (paging Time window), and the terminal monitors a paging channel in the PTW according to the DRX cycle (the DRX cycle Time is short, and it can be considered that the terminal is not dormant and can reach all the Time) so as to receive downlink data, and the terminal is in a dormant state in the rest of the Time. Currently, a Wake Up Signal (WUS), i.e. a PDCCH-based WUS, is introduced into NR, and the essence thereof is DCI Format 2_6 (downlink control information variable). The WUS is positioned in front of the PO, and the UE can determine the monitoring time of the WUS through the position of the PO.

The following is a detailed description with reference to examples:

(1) under the default condition, after the UE adopts the uplink pre-configured resource to send the uplink data, directly determining that the UE does not monitor the paging time between the uplink pre-configured resource and the downlink search space window, and monitoring a physical downlink control channel in the downlink search space window to obtain a paging message fed back by a network end according to the uplink data;

if the UE configures the wake-up signal, the UE does not monitor the WUS associated with the paging occasions.

(2) When an indication parameter X (i.e., a higher layer parameter) indicating a listening mode is configured:

when X is 1, after the UE adopts the uplink pre-configured resource to send uplink data, the UE does not monitor the paging time between the uplink pre-configured resource and the downlink search space window, and monitors a physical downlink control channel in the downlink search space window to obtain a paging message fed back by the network end according to the uplink data;

And when X is 0, monitoring the paging time between the uplink pre-configured resource and the downlink search space window according to the existing set mode.

(3) And when the UE is in the eDRX scene, monitoring the paging time between the uplink pre-configured resource and the downlink search space window according to the existing set mode.

When the UE is in a non-eDRX scene, the UE does not monitor the paging time between the uplink pre-configured resource and the downlink search space window, and monitors a physical downlink control channel in the downlink search space window to acquire a paging message fed back by a network end according to uplink data;

(4) As shown in fig. 3, after the UE sends uplink data by using the uplink pre-configured resource, it is directly determined to monitor a first paging occasion PO before the downlink search space window and with a time interval less than a first set time duration N1, so as to obtain a paging message (where an "x" number indicates that the paging occasion PO is not monitored).

Monitoring is only performed on a first paging occasion PO which is before a downlink search space window and has a time interval smaller than a first set duration N1, where N is configured by a higher layer signaling and may be in a unit of ms, a subframe, a time slot or a symbol.

In this embodiment, after the UE sends uplink data by using the PUR, the UE does not need to monitor the PO between the PUR and the PUR SS Window or only monitors a specific PO between the PUR and the PUR SS Window, thereby effectively saving power consumption caused by monitoring the PO and saving energy consumption overhead of the UE.

Example 3

In 4-step RACH Procedure (four-step random access Procedure):

the UE first completes downlink synchronization by reading MIB (main system information block) and SIB1 (system information block). The UE determines the resources for sending the preamble (i.e., the first message Msg1) to the network to indicate its intention to access the network by reading theSIB 1. If the Msg1 is correctly received by the network, the network sends a random access response message scrambled with the RA-RNTI (i.e., a second Msg2) to the UE. After sending Msg1, the UE may monitor Msg2 from the network using the RA-RNTI to descramble the message. The RA-RNTI is calculated from time and frequency resources of the RO. The Msg2 may contain TA, TC-RNTI, power adjustments, and resource indication forUE transmission Mgs 3. Then, the UE sends its identity and initial access setup (Msg3) to the network side through the uplink scheduling indication inMsg 2. Finally, the network may notify the UE of the completion of the initial access procedure through the Msg4, otherwise, the UE may determine that the initial access procedure fails.

As shown in fig. 4, in the 4-step RACH Procedure, the method for monitoring a paging message of this embodiment includes:

s201, after the first message Msg1 is sent, determining that the monitoring is not carried out on the paging moment between the first message Msg1 and the second message Msg2, and monitoring is carried out on thesecond message Msg 2;

and after the third message Msg3 is sent, determining that the third paging moment between the third message Msg3 and the fourth message Msg4 is not monitored, and monitoring thefourth message Msg 4. Or the like, or, alternatively,

monitoring a second paging moment before a second message Msg2 and with a time interval smaller than a second set time length after the first message Msg1 is sent;

In this embodiment, in the random access process, after the UE sends Msg1(Msg3), the UE does not need to monitor PO between Msg1 and Msg2 (PO between Msg3 and Msg4) or only monitor PO before Msg2(Msg4) and with an interval smaller than N, so that power consumption caused by monitoring PO is effectively saved, and energy consumption overhead of the UE is saved.

Example 4

The method for monitoring the paging message in this embodiment is a further improvement ofembodiment 3, and specifically:

in a 2-step RACH Procedure (four-step random access Procedure):

to further reduce the delay of random access, a two-step random access procedure is introduced, in which a UE completes the random access procedure by sending MsgA (containing Msg1 and Msg3) and receiving MsgB (containing Msg2 and Msg 4).

As shown in fig. 5, in the 2-step RACH Procedure, the method for monitoring a paging message of this embodiment includes:

s202, after the fifth message MsgA is sent, determining that monitoring is not performed on a fourth paging moment between the fifth message MsgA and the sixth message MsgB, and monitoring the sixth message MsgB; or the like, or, alternatively,

and after the fifth message MsgA is sent, monitoring a fourth paging moment which is before the sixth message MsgB and has a time interval smaller than a second set time length.

Step S201 or step S202 is preceded by:

pre-configuring a second indication parameter of the monitoring mode;

the third monitoring mode correspondingly indicates that the paging time between the first message Msg1 and the second message Msg2, the third message Msg3 and the fourth message Msg4, and the fifth message MsgA and the sixth message MsgB are monitored;

And configuring the second indication parameter and the second set time length by adopting RRC signaling or system information.

The monitoring method of the embodiment further includes:

determining a second target monitoring mode according to a second preset indication parameter;

the second target monitoring mode is a third monitoring mode or a fourth monitoring mode. Or the like, or, alternatively,

in addition, when the network is in an eDRX scene, determining to execute a third monitoring mode;

and when the non-eDRX scene is present, determining to execute a fourth monitoring mode.

The following is a detailed description with reference to examples:

(1) in default, after the UE sends Msg1(Msg3), the UE does not need to monitor the PO between Msg1 and Msg2 (the PO between Msg3 and Msg4), and directly monitors Msg2(Msg 4);

After the UE sends the MsgA, the UE directly monitors the MsgB without monitoring the PO between the MsgA and the MsgB;

when X is 1, after the UE sends Msg1(Msg3), the UE does not need to listen to PO between Msg1 and Msg2 (PO between Msg3 and Msg4), and directly listens to Msg2(Msg 4);

When X is 0, the paging time PO between Msg1 and Msg2 and the paging time PO between Msg3 and Msg4 are monitored in the conventional manner.

(3) When the eDRX scene is in, monitoring the paging time PO between the Msg1 and the Msg2 and the paging time PO between the Msg3 and the Msg4 according to the existing set mode.

When in a non-eDRX scene, the UE does not need to monitor the PO between Msg1 and Msg2 (the PO between Msg3 and Msg4), and directly monitors Msg2(Msg 4);

(4) After the UE sends Msg1(Msg3), as shown in FIG. 6, the UE only needs to listen to POs that are before the corresponding Msg2 and that are spaced from Msg2 by N2 and less than N (POs that are spaced from the corresponding Msg4 by less than N). Where N is configured by higher layer signaling, and the unit of N may be ms, subframe, slot or symbol (the "x" indicates that no monitoring is performed for the paging time PO, the same applies below).

After the UE sends MsgA, as shown in fig. 7, the UE only needs to monitor PO before MsgB and with a time interval from MsgB smaller than N2.

In this embodiment, in the random access process, after the UE sends Msg1(Msg3), the UE does not need to monitor PO between Msg1 and Msg2 (PO between Msg3 and Msg4) or only monitor PO before Msg2(Msg4) and with an interval smaller than N; after the UE sends the MsgA, the UE does not need to monitor PO between the MsgA and the MsgB or only monitors PO before the MsgB and with the interval smaller than N, so that power consumption caused by PO monitoring is effectively saved, and energy consumption expense of the UE is saved.

As shown in fig. 8, the monitoring system for paging messages of this embodiment includes an uplinkdata sending module 1, a first determiningmodule 2, and afirst monitoring module 3.

the second determiningmodule 5 is configured to determine, during a random access process, that no monitoring is performed on a paging time between the first message Msg1 and the second message Msg2 after the first message Msg1 is sent, and call thesecond monitoring module 6 to monitor thesecond message Msg 2;

thesecond monitoring module 6 is configured to determine not to monitor a paging time between the third message Msg3 and the fourth message Msg4 after the third message Msg3 is sent, and call thesecond monitoring module 6 to monitor thefourth message Msg 4.

Example 8

The monitoring system of the paging message of the present embodiment is a further improvement ofembodiment 7, specifically:

thesecond monitoring module 6 is further configured to monitor a second paging time before the second message Msg2 and at a time interval shorter than a second set time length after the first message Msg1 is sent in the random access process;

The second determiningmodule 5 is configured to determine, during the random access process, that the paging time between the fifth message MsgA and the sixth message MsgB is not monitored after the fifth message MsgA is sent, and call thesecond monitoring module 6 to monitor the sixth message MsgB.

Thesecond monitoring module 6 is further configured to monitor, during the random access process, after the fifth message MsgA is sent, a fourth paging time before the sixth message MsgB and at a time interval shorter than a second set time duration.

As shown in fig. 11, the monitoring system of this embodiment further includes a secondparameter configuration module 7;

the secondparameter configuration module 7 is used for configuring a second indication parameter of the monitoring mode in advance;

The second determiningmodule 5 is configured to determine a second target monitoring mode according to a second pre-configured indication parameter;

the second determiningmodule 5 is configured to determine to execute a third monitoring mode when the eDRX scene is located; the second determiningmodule 5 is further configured to determine to execute a fourth monitoring mode when the non-eDRX scenario is present.

In addition, the second indication parameter and the second set time duration are both configured by adopting RRC signaling or system information.

The following is a detailed description with reference to examples:

(4) After the UE sends Msg1(Msg3), as shown in FIG. 6, the UE only needs to listen to POs that are before the corresponding Msg2 and have a time interval with Msg2 less than N (POs that are less than N apart from the corresponding Msg 4). Where N is configured by higher layer signaling, and the unit of N may be ms, subframe, slot or symbol (the "x" indicates that no monitoring is performed for the paging time PO, the same applies below).
