Description

[Technical field]

[0001] The present disclosure relates to, but is not limited to, the wireless communication technical field, and in particular to a paging monitor method, apparatus, communication device and storage medium. [Background technology]

[0002] In communication technology, a terminal can consider a service that has certain requirements on power consumption and delay. For each enhanced discontinuous reception (eDRX) period, the terminal receives downlink data only within a set paging time window (PTW), and is in a dormant state for the rest of the time and does not receive downlink data. This DRX method can balance delay and power consumption in downlink services.

[0003] In the related art, when a terminal moves between different cells, there may be a cell that does not support eDRX. In this case, if the terminal moves to this cell that does not support eDRX execution, a paging monitor failure may occur, and the reliability of wireless communication may be deteriorated.

[0019] In an embodiment of the present disclosure, a paging cycle in which a terminal in a radio resource control (RRC) unconnected state performs paging monitoring in the cell is determined based on a determination result of whether a cell in which the terminal is located supports enhanced discontinuous reception (eDRX) in an RRC unconnected state, and an eDRX parameter for performing paging monitoring based on eDRX in an RRC unconnected state is pre-configured in the terminal.

Compared with a method of always performing paging monitoring using eDRX parameters regardless of which cell the terminal moves to, this can reduce paging monitoring failures when the cell does not support eDRX in an RRC unconnected state, and improve the reliability of wireless network communication.

As shown in Fig. 1, the wireless communication system is a communication system based on mobile communication technology, and the wireless communication system can include some user equipments 110 and some base stations 120.

[0026] User equipment 110 may refer to devices that provide voice and / or data connectivity to a user.

[0034] In order to facilitate the understanding of those skilled in the art, the embodiments of the present disclosure enumerate several embodiments to clearly describe the technical solutions of the embodiments of the present disclosure. Of course, those skilled in the art will understand that the several embodiments provided by the embodiments of the present disclosure can be implemented alone, can be implemented in combination with the methods of other embodiments in the embodiments of the present disclosure, and can be implemented alone or in combination with some methods in other related technologies, and the embodiments of the present disclosure are not limited thereto.

[0035] In order to better understand the technical solution described by any embodiment of the present disclosure, a paging monitor application scenario will be first described.

[0036] In one embodiment, referring to FIG. 2, one paging time window (PTW) is set in each eDRX cycle. Within the PTW, the terminal monitors the paging channel according to the DRX cycle (wherein the terminal is not inactive and data is considered to be always available because the time of the DRX cycle is short) to receive downlink data, and is in an idle state for the remaining time. Here, in the paging monitoring by eDRX, data is considered to be always available, but the delay is large. Here, since this delay depends on the setting of the eDRX cycle, it is possible to balance low power consumption and delay by setting the eDRX cycle.

[0037] In one embodiment, at least one of the following parameters needs to be negotiated between the terminal and the core network: 1, TeDRX,H:eDRX period, 2. L: PTW window length;

[0038] Now, referring to FIG. 3, the negotiation process between the terminal and the core network is as follows: A step a in which a base station transmits a message (which may be a system message) indicating allowed eDRX parameters and cell-specific DRX parameters to a terminal; A step b of the terminal sending a message to a core network device via a base station indicating terminal-specific DRX parameters and preferred DRX parameters; A step c of the core network device sending a message to the terminal via the base station indicating eDRX configuration parameters; and step d, the core network device paging the terminal based on the eDRX configuration parameters.

[0039] Here, this negotiation process can be performed between the terminal and the core network via non-access stratum messages, and this negotiation process is completely transparent to the base station.

[0040] In one example scenario, a Radio Resource Control (RRC) inactive state is introduced in New Radio (NR). In this case, the terminal needs to receive paging messages from the radio access network in addition to receiving paging messages from the core network. In one example, the radio access network assigns a short eDRX period in the RRC inactive state to the terminal. In one example, the radio access network also assigns a PTW window length to the terminal. Here, the PTW window start point and the PTW window start point assigned by the core network device may be the same.

[0041] In one embodiment, the core network device and the base station assign two sets of eDRX parameters (wherein each set of eDRX parameters may include an eDRX period and a PTW parameter) to the terminal, i.e., eDRX parameters in an RRC idle state and eDRX parameters in an RRC inactive state. In one embodiment, the base station may assign eDRX parameters in an RRC inactive state only if the eDRX parameters in the RRC idle state are configured. Here, the base station may explicitly indicate to the terminal whether it supports eDRX in an RRC inactive state or eDRX in an RRC idle state. Here, the indication may be made by a system message. Here, the explicit indication may refer to carrying an information field in an indication message indicating whether it supports eDRX in an RRC inactive state or eDRX in an RRC idle state.

[0042] In one embodiment, the eDRX period may be 2.56 s or more, for example, the eDRX period may be 2.56 s, 5.12 s, 10.24 s or greater than 10.24 s.

[0043] In one embodiment, in a non-eDRX scenario configuration (wherein the non-eDRX scenario may be a DRX scenario), the DRX monitoring operation by the terminal may be performed as follows. For a user in RRC idle state, T = min{UE specific DRX value, default paging cycle}, where UE specific DRX value is selectable, where UE specific DRX value is a terminal-specific DRX value, and default paging cycle is the default paging cycle. If the network does not provide a UE specific DRX value, T = min{UE specific DRX value, default paging cycle} = default paging cycle. For a user in RRC inactive state, T=min{UE specific DRX value, default paging cycle, RAN paging cycle}, where UE specific DRX value is selectable. UE specific DRX value is a terminal specific DRX value, default paging cycle is the default paging cycle, and RAN paging cycle is the radio access network paging cycle. Note that if the network does not provide a UE specific DRX value, T=min{UE specific DRX value, default paging cycle, RAN paging cycle}=min{default paging cycle, RAN paging cycle}. If the network does not provide a RAN paging cycle either, this formula becomes T=default paging cycle.

[0044] As shown in FIG. 4, an embodiment of the present disclosure provides a paging monitoring method, where the method is executed by a terminal, and the method includes the following step 41:

[0045] In step 41, a paging cycle is determined in which the terminal in a radio resource control (RRC) unconnected state performs paging monitoring in the cell based on a determination result of whether the cell in which the terminal in a radio resource control (RRC) unconnected state is located supports extended discontinuous reception (eDRX) in a RRC unconnected state; Here, eDRX parameters for performing paging monitoring based on eDRX in an RRC non-connected state are configured in advance in the terminal.

[0046] Here, the terminal may be, but is not limited to, a mobile phone, a tablet, a wearable device, an in-vehicle terminal, a Road Side Unit (RSU), a smart home terminal, an industrial sensor device, and / or a medical device, etc. For example, the smart home terminal may include a camera, a temperature collecting device, and a luminance collecting device, etc.

[0047] Here, the base station according to the present disclosure may be any type of base station, for example, a base station of a third generation mobile communication (3G) network, a base station of a fourth generation mobile communication (4G) network, a base station of a fifth generation mobile communication (5G) network, or any other evolved base station.

[0048] Here, the core network device according to the present disclosure may be a Unified Data Management (UDM) entity, an Access Control And Mobility Management Function (AMF) entity, or the like.

[0049] In an embodiment of the present disclosure, a terminal in an RRC unconnected state may be a terminal in a state other than the RRC connected state (RRC_CONNECTED), for example, a terminal in an RRC inactive state (RRC_INACTIVE) or a terminal in an RRC idle state (RRC_IDLE).

[0050] In one embodiment, the network may pre-configure the terminal with eDRX parameters for performing paging monitoring based on eDRX in an RRC unconnected state, or the terminal may determine the eDRX parameters based on a communication protocol, or any other possible method may be adopted to enable the terminal to determine the eDRX parameters. In the embodiment of the present disclosure, all of these methods can be referred to as "eDRX parameters are pre-configured in the terminal." Note that only a method in which the network can pre-configure the eDRX parameters in the terminal may be defined. In response to the terminal being able to determine the eDRX parameters for performing paging monitoring based on eDRX in an RRC unconnected state, the terminal in an RRC unconnected state determines a paging cycle for performing paging monitoring in the cell based on a determination result of whether a cell in which the terminal in an RRC unconnected state is located supports enhanced discontinuous reception (eDRX) in an RRC unconnected state. Here, the eDRX parameters include at least one of an eDRX cycle and a PTW. Here, the eDRX parameters may be parameters for performing eDRX in an RRC idle state, or may be parameters for performing eDRX in an RRC inactive state.

[0051] In one embodiment, the network side may indicate through a system message whether the cell in which the terminal is located supports eDRX in an RRC non-connected state. Here, supporting eDRX in an RRC non-connected state may mean supporting eDRX in an RRC idle state and / or an RRC inactive state. Not supporting eDRX in an RRC non-connected state may mean not supporting eDRX in an RRC idle state and / or an RRC inactive state. In addition, whether or not eDRX in an RRC non-connected state is supported may be determined based on the hardware attributes of the base station of the cell, may be determined based on the received configuration parameters, or may be determined based on a trigger scenario, and is not limited here.

[0052] In an embodiment, the network may preconfigure the terminal with eDRX parameters for performing paging monitoring based on eDRX in the RRC idle state and the RRC inactive state, or may determine the eDRX parameters based on a terminal communication protocol, or may adopt any other possible method for enabling the terminal to determine the eDRX parameters. In the embodiment of the present disclosure, all of these methods can be referred to as "eDRX parameters are preconfigured in the terminal." Note that only a method in which the network can preconfigure the eDRX parameters in the terminal may be defined. In response to the terminal being able to determine the eDRX parameters for performing paging monitoring based on eDRX in the RRC idle state and the RRC inactive state, the network determines a paging period for performing paging monitoring in the cell in the RRC idle state based on a determination result of whether the cell in which the terminal in the RRC idle state is located supports enhanced discontinuous reception (eDRX) in the RRC idle state.

[0053] In one embodiment, the network may preconfigure the eDRX parameters for performing paging monitoring based on eDRX in the RRC idle state and the RRC inactive state in the terminal, or may determine the eDRX parameters based on a terminal communication protocol, or may adopt any other possible method for enabling the terminal to determine the eDRX parameters. In the embodiment of the present disclosure, all of these methods can be referred to as "eDRX parameters are preconfigured in the terminal." Note that only a method in which the network can preconfigure the eDRX parameters in the terminal may be defined. In response to the terminal being able to determine the eDRX parameters for performing paging monitoring based on eDRX in the RRC idle state and the RRC inactive state, the network determines a paging period for performing paging monitoring in the cell in the RRC inactive state based on a determination result of whether the cell in which the terminal in the RRC inactive state is located supports enhanced discontinuous reception (eDRX) in the RRC inactive state.

[0054] In one embodiment, the network may pre-configure the terminal with eDRX parameters for performing paging monitoring based on eDRX in the RRC idle state, or may determine the eDRX parameters based on a terminal communication protocol, or may adopt any other possible method for enabling the terminal to determine the eDRX parameters. In the embodiment of the present disclosure, all of these methods can be referred to as "eDRX parameters are pre-configured in the terminal." Note that only a method in which the network can pre-configure the eDRX parameters in the terminal may be defined. In response to the terminal being pre-configured with eDRX parameters for performing paging monitoring based on eDRX in the RRC idle state, a paging period for the terminal in the RRC idle state to perform paging monitoring in the cell is determined based on a determination result of whether the cell in which the terminal in the RRC idle state is located supports enhanced discontinuous reception (eDRX) in the RRC idle state.

[0055] In one embodiment, the network may pre-configure the terminal with eDRX parameters for performing paging monitoring based on eDRX in the RRC inactive state, or may determine the eDRX parameters based on a terminal communication protocol, or may adopt any other possible method for enabling the terminal to determine the eDRX parameters. In the embodiment of the present disclosure, all of these methods can be referred to as "eDRX parameters are pre-configured in the terminal." Note that only a method in which the network can pre-configure the eDRX parameters in the terminal may be defined. In response to the terminal being pre-configured with eDRX parameters for performing paging monitoring based on eDRX in the RRC inactive state, a paging period for performing paging monitoring in the cell in the RRC inactive state is determined based on a determination result of whether the cell in which the terminal in the RRC inactive state is located supports enhanced discontinuous reception (eDRX) in the RRC inactive state.

[0056] In one embodiment, the network may pre-configure the terminal with eDRX parameters for performing paging monitoring based on eDRX in an RRC detached state, or may determine the eDRX parameters based on a terminal communication protocol, or may adopt any other possible method for enabling the terminal to determine the eDRX parameters. In the embodiment of the present disclosure, all of these methods can be referred to as "eDRX parameters are pre-configured in the terminal." Note that only the method in which the network can pre-configure the eDRX parameters in the terminal may be defined. In response to the determination result indicating that the cell supports eDRX in the RRC detached state, if the terminal determines that the paging period is the paging period indicated by the eDRX parameters, i.e., the cell supports eDRX in the RRC detached state, the terminal may perform paging monitoring based on the paging period indicated by the eDRX parameters. In another embodiment, in response to the determination result indicating that the cell does not support eDRX in the RRC detached state, the terminal determines that the paging period is a predetermined period. Here, the predetermined period may be a period determined based on a radio access paging period set by the network or a default radio access paging period. That is, if the cell does not support eDRX in the RRC non-connected state, the terminal does not perform paging monitoring based on the period indicated by the eDRX parameters, but performs paging monitoring using the predetermined period.

[0057] In an embodiment of the present disclosure, a paging cycle in which a terminal in a radio resource control (RRC) unconnected state performs paging monitoring in a cell is determined based on a determination result of whether a cell in which a terminal in a radio resource control (RRC) unconnected state is located supports enhanced discontinuous reception (eDRX) in an RRC unconnected state, and an eDRX parameter for performing paging monitoring based on eDRX in an RRC unconnected state is pre-configured in the terminal. Here, the paging cycle in which a terminal in an RRC unconnected state performs paging monitoring in a cell can be determined based on a determination result of whether a cell supports eDRX in an RRC unconnected state, and thus, the paging cycle can be adapted to the determination result. Compared with a method of always performing paging monitoring using eDRX parameters regardless of which cell the terminal moves to, it is possible to reduce failures of paging monitoring when a cell does not support eDRX in an RRC unconnected state and improve the reliability of wireless network communication.

[0058] It should be noted that the above solution is described with reference to the cell in which the terminal is located, but this is not the only scenario in which the embodiments of the present disclosure are applied. The terminal can also determine parameters related to paging monitoring at the time of handover based on the same technical solution, for example, when the terminal performs a cell handover, before, during, or after the handover, it can determine whether the cell to be handed over supports eDRX in an RRC non-connected state, and perform paging monitoring accordingly. Of course, the terminal can also select when performing a cell handover based on the same technical solution, for example, when the terminal performs a cell handover or during the cell handover, it can determine whether the candidate cell to be handed over supports eDRX in an RRC non-connected state, and determine the cell to be handed over based on the determination result and other related parameters (if any). It should be noted that the above expression also applies to each embodiment of the present disclosure, and due to space limitations, the following description will be omitted.

[0059] It will be understood by those skilled in the art that the methods provided by the embodiments of the present disclosure may be performed alone or together with some methods of the embodiments of the present disclosure or some methods in related art.

[0060] As shown in FIG. 5, an embodiment of the present disclosure provides a paging monitoring method, where the method is executed by a terminal, and the method includes the following step 51:

[0061] In step 51, in response to determining that the cell in which the terminal is located supports eDRX in an RRC non-connected state, determining that the paging cycle is a cycle indicated by an eDRX parameter; or In response to determining that the cell in which the terminal is located does not support eDRX in an RRC non-connected state, it is determined that the paging period is a predetermined period.

[0062] In addition, the terminal's determination of whether the serving cell supports eDRX in the RRC unconnected state may include the terminal in the RRC unconnected state determining that the serving cell supports eDRX in the RRC unconnected state, or the terminal in the RRC unconnected state determining that the serving cell does not support eDRX in the RRC unconnected state. In one embodiment, the network side may indicate through a system message whether the serving cell of the terminal supports or does not support eDRX in the RRC unconnected state. In this case, the terminal may determine whether the serving cell supports eDRX in the RRC unconnected state based on the indication of the system message.

[0063] It should be noted that the step of determining that the cell in which the terminal is located supports eDRX in an RRC non-connected state is an independent step, and the step of determining that the cell in which the terminal is located does not support eDRX in an RRC non-connected state is also an independent step, where these two steps may be performed independently or together, where the operation of determining whether the cell supports eDRX in an RRC non-connected state may be different from the operation of determining whether the cell supports eDRX or does not support eDRX.

[0064] Here, in response to determining that the serving cell supports eDRX in an RRC non-connected state, it is determined that the paging period is a period indicated by the eDRX parameters, and since the cell supports eDRX in an RRC non-connected state, the period indicated by the eDRX parameters can be directly used to perform paging monitoring.

[0065] Here, in response to determining that the serving cell does not support eDRX in an RRC unconnected state, it is determined that the paging cycle is a predetermined cycle. Since the cell does not support eDRX in an RRC unconnected state, performing paging monitoring using eDRX in an RRC unconnected state will cause a paging monitoring failure, and therefore it is necessary to perform paging monitoring using a predetermined cycle rather than using a cycle indicated by the eDRX parameters.

[0066] In one embodiment, in response to a determination that the serving cell does not support eDRX in the RRC non-connected state, paging monitoring may be performed based on a predetermined period determined based on a radio access paging period set by the network. Alternatively, in response to a determination result indicating that the cell does not support eDRX in the RRC non-connected state, paging monitoring may be performed based on a predetermined period determined based on a default radio access paging period set by the network. Here, the default radio access paging period may be specified by a protocol or may be set by the network. The default radio access paging period may be the eDRX period in the RRC inactive state or the radio access paging period set by the network. Also, for example, the protocol specifies that the default radio access paging period is 2.56 s. Here, the default radio access paging period set by the network may be used when eDRX in the RRC inactive state is disabled or when eDRX in the RRC inactive state is not supported.

[0067] It will be understood by those skilled in the art that the methods provided by the embodiments of the present disclosure may be performed alone or together with some methods of the embodiments of the present disclosure or some methods in related technologies.

[0068] In one embodiment, in response to determining that the cell in which the terminal is located does not support eDRX in the RRC inactive state, a paging time window (PTW) in the RRC inactive state indicated by the eDRX parameters is disabled.

[0069] Here, the PTW in the RRC inactive state being invalidated may mean that the terminal does not use the PTW in the RRC inactive state and performs paging monitoring. In one embodiment, the stored PTW parameter in the RRC inactive state may be deleted.

[0070] In one embodiment, in response to determining that the cell in which the terminal is located does not support eDRX in the RRC inactive state, the eDRX period in the RRC inactive state indicated by the eDRX parameters is disabled.

[0071] Here, disabling the eDRX cycle in the RRC inactive state may mean that the terminal no longer uses the eDRX cycle in the RRC inactive state and performs paging monitoring. In one embodiment, the stored eDRX cycle in the RRC inactive state may be deleted. Here, after the eDRX cycle in the RRC inactive state is disabled, it is necessary to perform paging monitoring using a predetermined cycle. Here, the predetermined cycle may be determined based on a radio access paging cycle set by the network or a default radio access paging cycle.

[0072] In one embodiment, in response to determining that the cell in which the terminal is located does not support eDRX in the RRC inactive state, both the paging time window (PTW) in the RRC inactive state and the eDRX period in the RRC inactive state indicated by the eDRX parameters are disabled.

[0073] In one embodiment, in response to determining that the cell in which the terminal is located does not support eDRX in RRC idle state, the PTW in RRC idle state indicated by the eDRX parameters is disabled.

[0074] Here, the invalidation of the PTW in the RRC idle state may mean that the terminal no longer uses the PTW in the RRC idle state and performs paging monitoring. In one embodiment, the stored PTW parameter in the RRC idle state may be deleted.

[0075] In one embodiment, in response to determining that the cell in which the terminal is located does not support eDRX in RRC idle state, the eDRX period in RRC idle state indicated by the eDRX parameters is disabled.

[0076] Here, disabling the eDRX cycle in the RRC idle state may mean that the terminal no longer uses the eDRX cycle in the RRC idle state and performs paging monitoring. In one embodiment, the stored eDRX cycle in the RRC idle state may be deleted. Here, after the eDRX cycle in the RRC idle state is disabled, it is necessary to perform paging monitoring using a predetermined cycle. Here, the predetermined cycle may be determined based on a radio access paging cycle set by the network or a default radio access paging cycle.

[0077] In one embodiment, in response to determining that the cell in which the terminal is located does not support eDRX in RRC idle state, the PTW in the RRC inactive state indicated by the eDRX parameters is disabled.

[0078] In response to the cell not supporting eDRX in the RRC idle state, the cell also does not support eDRX in the RRC inactive state. Here, the PTW in the RRC inactive state being invalidated may mean that the terminal no longer uses the PTW in the RRC inactive state and performs paging monitoring. In one embodiment, the stored PTW parameter in the RRC inactive state may be deleted.

[0079] In one embodiment, in response to determining that the cell in which the terminal is located does not support eDRX in RRC idle state, the eDRX period in RRC inactive state indicated by the eDRX parameters is disabled.

[0080] In response to the cell not supporting eDRX in the RRC idle state, the cell also does not support eDRX in the RRC inactive state. Here, disabling the eDRX cycle in the RRC inactive state may mean that the terminal no longer uses the eDRX cycle in the RRC inactive state and performs paging monitoring. In one embodiment, the stored eDRX cycle in the RRC inactive state may be deleted. Here, after the eDRX cycle in the RRC inactive state is disabled, it is necessary to perform paging monitoring using a predetermined cycle. Here, the predetermined cycle may be determined based on a radio access paging cycle set by the network or a default radio access paging cycle.

[0081] As shown in FIG. 6, an embodiment of the present disclosure provides a paging monitoring method, where the method is executed by a terminal, and the method includes the following step 61:

[0082] In step 61, in response to determining that the cell in which the terminal is located does not support eDRX in an RRC non-connected state, a predetermined period is determined based on a period indicated by an eDRX parameter, and the terminal performs paging monitoring based on the predetermined period; or In response to determining that the cell in which the terminal is located does not support eDRX in the RRC non-connected state and the period indicated by the eDRX parameter in the RRC non-active state is equal to or less than a period threshold, determining a predetermined period in the RRC non-active state based on a default radio access paging period, and the terminal performs paging monitoring based on the predetermined period; or In response to determining that the cell in which the terminal is located does not support eDRX in the RRC non-connected state and the period indicated by the eDRX parameters in the RRC non-active state is equal to or greater than the period threshold, a predetermined period in the RRC non-active state is determined based on a radio access paging period set by the network, and the terminal performs paging monitoring based on the predetermined period.

In one embodiment, the protocol stipulates that the value of the default radio access paging period is 2.56 s. In one embodiment, the default radio access paging period stipulated by the protocol is the period indicated by the eDRX parameters in the RRC inactive state, in which case the period is equal to or less than a value b (where the value b may be 10.24 s).

[0091] In one embodiment, in response to the period indicated by the eDRX parameters in the RRC idle state configured for the terminal in the RRC inactive state being equal to or greater than the a value (where the a value may be 10.24 s) and the period indicated by the eDRX parameters in the RRC inactive state being equal to or less than the b value (where the b value may be 10.24 s), if the terminal moves to a cell that does not support eDRX in the RRC inactive state, the terminal performs paging monitoring according to a predetermined period T within the PTW window, where T=min{terminal-specific DRX value, default paging period, default radio access paging period}, where paging monitoring can be performed according to a default radio access paging period outside the PTW window, where the default radio access paging period may be configured by the network or may be stipulated by a predetermined protocol.
