[0024] The technical solutions in the embodiments of the present invention will be described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0025] The following is a brief description of the terms involved in the embodiments of the present application, as shown below:

[0026] 1. Radio Resource Control (RRC) Status of User Equipment (UE)

[0027] In the Long Term Evolution (LTE) system and the 5G system, there are three RRC protocol states, namely, RRC idle (RRC_IDLE) state, RRC inactive (RRC_INACTIVE) state and RRC connected (RRC_CONNECTED) state.

[0028] RRC_IDLE: Mobility is based on UE cell selection reselection, paging is initiated by the core network (CN), and the paging area is configured by the CN. There is no UE access stratum (AS) context on the base station side. There is no RRC connection.

[0029] RRC_INACTIVE: Mobility is based on UE cell selection reselection, there is a connection between CN-NR (New Radio), the UE AS context exists on a base station, paging is triggered by the Radio Access Network (RAN), the RAN-based paging area is managed by the RAN, and the network side knows the UE's location based on the RAN paging area level.

[0030] RRC_CONNECTED: An RRC connection exists, and a UE AS context exists between the base station and the UE. The network knows the location of the UE at a specific cell level. Mobility is controlled by the network. Data can be transmitted between the UE and the base station.

[0031] 2. 5G NR paging mechanism

[0032] The main function of Paging is to enable the network to page the UE through a paging message when the UE is in the RRC_IDLE state or RRC_INACTIVE state, or to notify the UE of system message changes or earthquake tsunami / public warning information through a short message (applicable to all RRC states of the UE, including the connected state).

[0033] Paging includes the Physical Downlink Control Channel (PDCCH) scrambled by the Paging Radio Network Temporary Identifier (P-RNTI) and the Physical Downlink Share Channel (PDSCH) scheduled by the PDCCH. Paging message is transmitted in PDSCH, and short message is 8 bits in PDCCH.

[0034] For UE in RRC_IDLE state or RRC_INACTIVE state, since there is no other data communication between the UE and the network, in order to save power for the terminal, the UE can monitor the Paging channel discontinuously, that is, adopt the Paging DRX (Discontinuous Reception) mechanism. Under the Paging DRX mechanism, the UE only needs to monitor Paging during one PO in each DRXcycle. PO is a series of PDCCH monitoring opportunities and it can be composed of multiple time slots. There is also the concept of Paging Frame (PF), which refers to a radio frame (fixed 10ms), which can contain multiple POs or the starting positions of multiple POs.

[0035] The Paging DRX cycle is determined by the common cycle in the system broadcast and the dedicated cycle configured in the high-level signaling (non-accessstratum (NAS) signaling). The UE takes the minimum cycle of the two as the Paging Cycle cycle. From the network perspective, a paging DRX cycle can have multiple POs. The location where the UE monitors the PO is related to the UE's identity (ID). The specific method for determining the PF and PO of a UE in a Paging DRX is as follows (TS 38.304):

[0036] The PF system frame number (SFN) is determined by the following formula:

[0037] (SFN+PF_offset)mod T=(T div N)*(UE_ID mod N)

[0038] The index (i_s) of a PO in a PF is determined by the following formula:

[0039] i_s=floor(UE_ID / N)mod Ns

[0040] The explanations of some of the above parameters are as follows:

[0041] T: The DRX cycle of the UE receiving paging. The network will broadcast a default DRX cycle. If the RRC / higher layer configures a UE-specific DRX cycle for the UE, the minimum of the DRX cycle broadcast by the network and the UE-specific DRX cycle configured by the RRC / higher layer will be used as the DRX cycle of the UE. If the RRC / higher layer does not configure a UE-specific DRX cycle for the UE, the DRX cycle broadcast by the network will be used as the DRX cycle of the UE.

[0042] N: the number of PFs included in a DRX cycle;

[0043] Ns: the number of POs contained in a PF;

[0044] PF_offset: A time domain offset used to determine PF;

[0045] UE_ID: 5G-S-TMSI mod 1024.

[0046] The configuration of the above parameters is as follows:

[0047]

[0048] For a UE, according to the above formula, the position of PF and the index of PO in a Paging DRX cycle can be known. TS 38.304 stipulates that PO is composed of multiple PDCCH monitoring occasions. A PO contains X PDCCH monitoring occasions, where X is equal to the number of synchronization signal blocks (SSB) actually sent in the Master Information Block (MIB).

[0049] After the UE knows the PF, the index of the PO, and the number of PDCCH monitoring occasions in the PO, it only needs to know the starting position of the first PDCCH monitoring occasion of the PO through the relevant configuration parameters. The starting position can be configured through high-level signaling or obtained based on the PO index. The UE blindly detects the Paging message based on the determined PO.

[0050] 3. Long Term Evolution (LTE) paging mechanism

[0051] In the LTE system, the PagingDRX mechanism is also used for UEs in the RRC_IDLE state or RRC_INACTIVE state. Similar to the NR system, under the PagingDRX mechanism, the UE only needs to monitor Paging during a PO period in each DRX cycle. The LTE system also defines the concepts of PF and PO. Unlike the NR system, in the LTE system, PO corresponds to a subframe within the PF.

[0052] Similar to the NR system, in the LTE system, for a UE in the RRC_IDLE state or the RRC_INACTIVE state, the UE calculates its PO based on parameters such as the UE ID and T. T represents the DRX cycle of the UE receiving Paging, which is determined as follows:

[0053] For a UE in RRC_IDLE state, if the upper layer configures extended DRX (eDRX) for the UE and the configured eDRX cycle is 5.12s, T is taken as 5.12s. Otherwise, if the upper layer configures a UE-specific DRX cycle for the UE, the minimum of the network broadcast DRX cycle and the UE-specific DRX cycle configured by the upper layer is taken as T. If the upper layer does not configure a UE-specific DRX cycle for the UE, the network broadcast DRX cycle is taken as T.

[0054] For a UE in RRC_INACTIVE state, if the upper layer has not configured eDRX for the UE, the minimum of the DRX cycle broadcast by the network and the UE-specific DRX cycle configured by RRC / upper layer is used as T. Otherwise, if the upper layer has configured eDRX for the UE, the minimum of the DRX cycle broadcast by the network and the UE-specific DRX cycle configured by RRC / upper layer is used as T during the paging time window (PTW); outside the PTW, the UE-specific DRX cycle configured by RRC is used as T.

[0055] 4. LTE eDRX mechanism

[0056] Considering that the services of NB-IoT and eMTC terminals are relatively simple and their service activity is low, these terminals are in a non-connected state most of the time. In addition, considering that the services of these terminals are not sensitive to latency requirements, in order to further save power in a non-connected state, LTE introduces the eDRX mechanism for these terminals, which can support a larger paging cycle, that is, a paging cycle greater than 256 SFNs. In LTE, the minimum value of the eDRX cycle configured by the high layer is 5.12s.

[0057] For a UE configured with eDRX, if the eDRX cycle of the UE is 5.12s, the UE calculates its corresponding PO based on T=5.12s. If the eDRX cycle of the UE is greater than or equal to 1 Hyper System Frame Number (H-SFN), the UE monitors the P-RNTI-scrambled PDCCH on its PO within the PTW time window within an eDRX cycle. Among them, PTW is exclusive to the UE and is determined according to the paging hyperframe (PH), a starting time point PTW_start and an ending time point PTW_end located within the PH.

[0058] PH is an H-SFN that meets the following conditions:

[0059] H-SFN mod TeDRX, H=(UE_ID_H mod TeDRX,H)

[0060] Among them, UE_ID_H is obtained based on the hash ID, TeDRX,H is the eDRX cycle in superframes, which is configured by AMF.

[0061] PTW_start is the starting radio frame number of PTW, which is an SFN that meets the following conditions:

[0062] SFN=256*ieDRX

[0063] ieDRX=floor(UE_ID_H / TeDRX,H)mod 4

[0064] PTW_end is the end radio frame number of PTW, which is the SFN that meets the following conditions:

[0065] SFN=(PTW_start+L*100-1)mod 1024, where

[0066] Wherein, L is the window length of PTW, which is configured by the Access and Mobility Management Function (AMF).

[0067] 5. NR RedCap (reduced capability) eDRX mechanism

[0068] In the R17NR work items, the 3GPP RAN Plenary agreed to study the low-capability NR terminal project (RP-193238). One of the goals of this project is:

[0069] Study UE power saving and battery lifetime enhancement for reducedcapability UEs in applicable use cases(egdelay tolerant)[RAN2,RAN1]:

[0070] Reduced PDCCH monitoring by smaller numbers of blind decodes and CCElimits[RAN1].

[0071] Extended DRX for RRC Inactive and / or Idle[RAN2]

[0072] RRM relaxation for stationary devices[RAN2]

[0073] That is, for low-capability NR terminals, the eDRX mechanism in idle or inactive state is introduced to save terminal power and extend battery life.

[0074] Currently, NR RedCap is in the SI stage. The two recent RAN2 meetings (RAN2#111e and RAN2#112e) have reached the following conclusions on the eDRX mechanism of RedCap:

[0075] For the RRC_IDLE state, the DRX cycle is extended to greater than 2621.44s as a baseline. At the same time, it can be studied whether it is necessary to support a larger eDRX cycle (for example, 10485.76s). For the RRC_INACTIVE state, the DRX cycle is extended to 10.24s as a baseline. Whether it is necessary to support a larger DRX cycle can be discussed at the next meeting.

[0076] RAN2 needs to study whether the eDRX cycle in RRC_IDLE and RRC_INACTIVE states needs to support a value less than 5.12s;

[0077] For UEs in RRC_IDLE and RRC_INACTIVE states, if the maximum supported DRX cycle exceeds 10.24s, the eDRX mechanism in LTE with an eDRX cycle exceeding 10.24s (i.e., using PTW, PH, etc.) is used as the baseline. For UEs in RRC_IDLE and RRC_INACTIVE states, if the eDRX cycle is less than 10.24s, paging monitoring does not use PTW and PH, etc.

[0078] For UEs in RRC_IDLE and RRC_INACTIVE states, if the eDRX cycle is equal to 10.24s, the basic assumption is that PTW and PH are not used, but other solutions are not excluded.

[0079] On the one hand, in the LTE system, for UE in RRC_INACTIVE state, if the high layer configures eDRX for the UE, the current standard defines the behavior of UE monitoring paging during PTW and the behavior of UE monitoring paging outside PTW. In the eDRX cycle values ​​supported by LTE, when the eDRX cycle is greater than or equal to 10.24s, paging monitoring uses PTW; and when the eDRX cycle is equal to 5.12s, paging monitoring does not use PTW. When the eDRX cycle is configured as 5.12s, the behavior of UE monitoring paging in RRC_IDLE state is clear, while the behavior of UE monitoring paging in RRC_INACTIVE state is unclear. For example, how should the UE determine the DRX cycle T for monitoring paging at this time?

[0080] On the other hand, in the NR system, based on the conclusions of the RAN2 meeting for the RedCap SI phase, for RedCap UEs in the RRC_INACTIVE state, there is no conclusion yet on whether the RRC_INACTIVE state should support a DRX cycle greater than 10.24s. In other words, in order to extend the RAN DRX cycle configured by the network, it is still unclear whether to directly extend the value range of the current parameter ran-PagingCycle or to introduce a new parameter RAN eDRX cycle to correspond to the extended DRX cycle configuration.

[0081] On the other hand, like the UE in the LTE system, if the eDRX cycle configured by the high layer and the DRX cycle / eDRX cycle configured by the RRC (if the RAN eDRX cycle configuration parameter is introduced) are both less than (or equal to) 10.24s, that is, paging monitoring does not use PTW, then if the UE determines to monitor the DRX cycle of paging, it is also a problem that needs to be solved.

[0082] The technical solutions of the embodiments of the present application can be applied to various communication systems, such as: Global System of Mobile communication (GSM) system, Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, Advanced Long Term Evolution (LTE-A) system, New Radio (NR) system, NR system evolution system, LTE on unlicensed spectrum (LTE-U) system, NR on unlicensed spectrum (NR-U) system, Non-Terrestrial Networks (NTN) system, Universal Mobile Telecommunication System (UMTS), Wireless Local Area Networks (WLAN), Wireless Fidelity (Wireless Fidelity) system.

[0097] The technical solution of the present invention is further described below by way of embodiments. Figure 2 FIG. 1 is a schematic diagram of an embodiment of a method for determining a paging cycle in an embodiment of the present invention, which may include:

[0098] 201. The terminal device receives the first cycle parameter configured from the network device.

[0099] The first cycle parameter includes at least one of a CN eDRX cycle, a RAN eDRX cycle, a CN DRX cycle, a RAN DRX cycle, and a default Paging Cycle cycle of a cell indicated by a system message.

[0100] 202. For a terminal device in a radio resource control inactive RRC_INACTIVE state, if the terminal device does not use a paging time window PTW and / or a paging superframe PH for monitoring paging under the configuration of a first cycle parameter, the terminal device determines a period for monitoring paging according to the first cycle parameter.

[0101] 203. The terminal device calculates a corresponding subframe PO according to the DRX cycle of the monitored paging and the identifier of the terminal device.

[0102] The following describes two implementations of the terminal device determining the period of monitoring paging according to the first period parameter, as shown below:

[0103] Implementation 1:

[0104] When the terminal device supports configuring the CN eDRX cycle but does not support configuring the RAN eDRX cycle, the period for monitoring paging is determined to be a smaller value between the CN eDRX cycle and the ran-PagingCycle cycle, or a minimum value between the CN eDRX cycle, the ran-PagingCycle cycle and the defaultPagingCycle cycle.

[0105] It is understandable that only CN supports configuring the CN eDRX cycle through NAS signaling, and RAN does not support configuring the RAN eDRX cycle through RRC signaling (for example, the maximum value of the RAN paging cycle that can be configured by the base station does not exceed 10.24s). If the network configures the CN eDRX cycle for the UE, and does not use PTW and / or PH for the configured CN eDRX cycle, then for the UE in the RRC_INACTIVE state, it is determined that the DRX cycle for monitoring paging is the smaller value of the CN eDRX cycle and the ran-PagingCycle, or the smallest value of the CN eDRX cycle, the ran-PagingCycle and the defaultPagingCycle.

[0106] 1. Optionally, the terminal device receives a first cycle parameter configured by the network device, that is, a DRX-related parameter and an eDRX-related parameter used to determine the paging cycle, which may include:

[0107] a) Receive DRX parameters configured by NAS message from CN, including UE-specific CN DRX cycle;

[0108] b) Receive eDRX parameters configured by NAS message from CN, including eDRX cycle CN eDRX cycle;

[0109] c) receiving the default paging cycle of the cell indicated by the system message;

[0110] d) Receive the RRC release message from the RAN to instruct the UE to enter the RRC_INACTIVE state, and configure the UE-specific RAN paging cycle (ran-PagingCycle).

[0111] 2. Optionally, the terminal device determines a period for monitoring paging according to the first period parameter, which can be described in the following cases:

[0112] Case 1:

[0113] Without considering the defaultPagingCycle period, the terminal device determines the period of monitoring paging according to the first period parameter, which may include:

[0114] a) If the RAN configures the ran-PagingCycle period, the terminal device determines the period for monitoring paging to be the smaller value between the CN eDRX period and the ran-PagingCycle period.

[0115] Exemplarily, if the RAN configures the UE with a ran-PagingCycle cycle, the paging monitoring cycle T=min{CN eDRX cycle, ran-PagingCycle}.

[0116] b) If the RAN does not configure the ran-PagingCycle period, the terminal device determines that the period for monitoring paging is the CN eDRX period.

[0117] Exemplarily, if the RAN does not configure the UE with a ran-PagingCycle, the period of monitoring paging T = CN eDRX period.

[0118] Case 2:

[0119] In the case of considering the defaultPagingCycle period, the terminal device determines the period of monitoring paging according to the first period parameter, which may include:

[0120] a) If the RAN configures the ran-PagingCycle cycle, the terminal device determines the period of monitoring paging to be the smallest value among the CN eDRX cycle, the ran-PagingCycle cycle and the defaultPagingCycle cycle.

[0121] For example, if the RAN configures the UE with a ran-PagingCycle cycle, the paging monitoring cycle T = min{CN eDRX cycle, ran-PagingCycle cycle, defaultPagingCycle cycle}

[0122] b) If the RAN does not configure the ran-PagingCycle period, the terminal device determines the period of monitoring paging to be the minimum value between the CN eDRX period and the defaultPagingCycle period.

[0123] Exemplarily, if the RAN does not configure the UE with a ran-PagingCycle cycle, the paging monitoring cycle T = min{CN eDRX cycle, defaultPagingCycle cycle}.

[0124] For example, regarding the above-mentioned situation 1 and situation 2, as Figure 3A FIG. 4 is a schematic diagram showing a terminal device determining a period for monitoring paging in an embodiment of the present invention.

[0125] 3. Optionally, for a UE in the RRC_INACTIVE state, the UE calculates its corresponding PO based on the UE ID, paging cycle T, etc.

[0126] Implementation 2:

[0127] In the case that the terminal device supports CN configuration of CN eDRX cycle and RAN configuration of RAN eDRX cycle, the period for monitoring paging is determined to be at least one of the CN eDRX cycle, the RAN eDRX cycle, the CN DRX cycle, the RAN DRX cycle, and the default paging cycle defaultPagingCycle cycle.

[0128] It is understandable that both NAS-configured CN eDRX and RRC-configured RAN eDRX are supported (for example, the maximum value of the RAN paging cycle that can be configured by the base station exceeds 10.24s). If the network configures the CN eDRX cycle and / or RANeDRX cycle for the UE, and PTW and / or PH are not used for the configured CN eDRX cycle and RAN eDRX cycle (for example, for RedCap UE, the CN eDRX cycle configured by the CN and the RAN eDRX cycle configured by the base station are both 5.12s), then for the UE in RRC_INACTIVE, the DRX cycle for monitoring paging of the UE is determined according to at least one of the configured CN eDRX cycle, RAN eDRX cycle, CN DRX cycle, RAN DRX cycle, and the default paging cycle of the cell indicated by the system message.

[0129] 1. Optionally, the terminal device receives a first cycle parameter configured by the network device, that is, a DRX-related parameter and an eDRX-related parameter used to determine the paging cycle, which may include:

[0130] a) Receive DRX parameters configured by NAS message from CN, including UE-specific CN DRX cycle;

[0131] b) Receive eDRX parameters configured by NAS message from CN, including eDRX cycle CN eDRX cycle;

[0132] c) receiving the default paging cycle of the cell indicated by the system message;

[0133] d) Receive the RRC release message from the RAN to instruct the UE to enter the RRC_INACTIVE state, and configure the UE-specific RAN paging cycle (ran-PagingCycle) and the UE-specific RAN eDRX cycle.

[0134] 2. Optionally, the terminal device determines a period for monitoring paging according to the first period parameter, which can be described in the following cases:

[0135] Case 1:

[0136] If the CN is configured with the CN eDRX cycle and the RAN is configured with the RAN eDRX cycle, the terminal device determines the period for monitoring paging to be a smaller value between the CN eDRX cycle and the RAN eDRX cycle.

[0137] For example, if the CN configures the CN eDRX cycle for the UE through NAS signaling, and the RAN configures the RAN eDRX cycle for the UE through RRC signaling, the monitoring paging cycle T = min{CN eDRX cycle, RAN eDRX cycle}. Figure 3B FIG. 4 is another schematic diagram showing a terminal device determining a period for monitoring paging in an embodiment of the present invention.

[0138] Case 2:

[0139] When the CN is configured with the CN eDRX cycle, the RAN is not configured with the RAN eDRX cycle, and the defaultPagingCycle cycle is not considered, the terminal device determines the cycle for monitoring paging according to the first cycle parameter, including:

[0140] a) If the RAN configures the ran-PagingCycle period, the terminal device determines the period for monitoring Paging to be the smaller value between the CN eDRX period and the ran-PagingCycle period.

[0141] Exemplarily, if the RAN configures the ran-PagingCycle period for the UE through RRC signaling, the period of monitoring Paging is T=min{CN eDRX period, ran-PagingCycle}.

[0142] b) If the RAN does not configure the ran-PagingCycle period, the terminal device determines that the period for monitoring Paging is the CN eDRX period.

[0143] Exemplarily, if the RAN does not configure the RAN-PagingCycle period to the UE through RRC signaling, the period T for monitoring Paging = CN eDRX period.

[0144] Case 3:

[0145] When the CN is configured with the CN eDRX cycle and the RAN is not configured with the RAN eDRX cycle, and the defaultPagingCycle cycle is considered, the terminal device determines, according to the first cycle parameter, a cycle for monitoring paging, including:

[0146] a) If the RAN configures the ran-PagingCycle cycle, the terminal device determines the period of monitoring paging to be the smallest value among the CN eDRX cycle, the ran-PagingCycle cycle and the defaultPagingCycle cycle.

[0147] Exemplarily, if the RAN configures the ran-PagingCycle cycle for the UE through RRC signaling, the cycle of monitoring Paging is T=min{CN eDRX cycle, ran-PagingCycle cycle, defaultPagingCycle cycle}.

[0148] b) If the RAN does not configure the ran-PagingCycle period, the terminal device determines the period of monitoring paging to be the minimum value between the CN eDRX period and the defaultPagingCycle period.

[0149] Exemplarily, if the RAN does not configure the RAN-PagingCycle cycle to the UE through RRC signaling, the cycle of monitoring Paging is T=min{CN eDRX cycle, defaultPagingCycle cycle}.

[0150] Regarding the above cases 2 and 3, if Figure 3C FIG. 4 is another schematic diagram showing a terminal device determining a period for monitoring paging in an embodiment of the present invention.

[0151] Case 4: When the CN does not configure the CN eDRX cycle, and the RAN configures the RAN eDRX cycle, and the defaultPagingCycle cycle is considered, the terminal device determines the cycle for monitoring paging according to the first cycle parameter, including:

[0152] a) If the CN configures the CN DRX cycle, the terminal device determines the period of monitoring paging to be the smallest value among the CN DRX cycle, the defaultPagingCycle cycle and the RAN eDRX cycle.

[0153] Exemplarily, if the CN configures the CN DRX cycle for the UE, the period of monitoring Paging is T=min{CN DRX cycle, defaultPagingCycle cycle, RAN eDRX cycle}.

[0154] b) If the CN does not configure the CN DRX cycle, the terminal device determines the period of monitoring paging to be the minimum value between the defaultPagingCycle period and the RAN eDRX period.

[0155] For example, if the CN does not configure the CN DRX cycle for the UE, the Paging monitoring cycle T = min{defaultPagingCycle cycle, RAN eDRX cycle}. Figure 3D FIG. 4 is another schematic diagram showing a terminal device determining a period for monitoring paging in an embodiment of the present invention.

[0156] 3. Optionally, for a UE in the RRC_INACTIVE state, the UE calculates its corresponding PO based on the UE ID, paging cycle T, etc.

[0157] It should be noted that the period of monitoring paging may also be referred to as paging period.

[0158] In an embodiment of the present invention, a method for determining a paging cycle for a UE in an RRC_INACTIVE state is disclosed. For a terminal device in an RRC_INACTIVE state where radio resource control is not activated, if the terminal device does not use a paging time window PTW and / or a paging superframe PH for monitoring paging under the configuration of a first cycle parameter, the terminal device determines the period for monitoring paging according to the first cycle parameter; wherein the first cycle parameter includes at least one of a CN eDRX cycle, a RAN eDRX cycle, a CN DRX cycle, a RAN DRX cycle, and a default paging cycle of a cell indicated by a system message. Using this method, for a UE in an RRC_INACTIVE state that is configured with an eDRX cycle and does not use PTW and / or PH under the eDRX cycle configuration, the behavior of the UE monitoring paging is clarified, which can not only ensure the paging performance, but also take into account the terminal energy saving requirements.

[0159] Specifically: For the case where only CN configuration of CN eDRX is supported and RAN configuration of RAN eDRX is not supported, the UE in the RRC_INACTIVE state determines that its DRX cycle for monitoring paging is the smaller value between the CN eDRX cycle and the ran-PagingCycle cycle, or the smallest value among the CN eDRX cycle, the ran-PagingCycle cycle and the defaultPagingCycle cycle. For the case where both CN configuration of CN eDRX and RAN configuration of RAN eDRX are supported, the UE in the RRC_INACTIVE state determines the DRX cycle for monitoring paging of the UE according to at least one of the configured CN eDRX cycle, RAN eDRX cycle, CN DRX cycle, RANDRX cycle, and the default paging cycle of the cell indicated by the system message.

[0160] like Figure 4 FIG. 1 is a schematic diagram of an embodiment of a terminal device in an embodiment of the present invention, which may include:

[0161] The processing module 401 is used for determining the period of monitoring paging for a terminal device in a radio resource control inactive RRC_INACTIVE state, if the terminal device does not use a paging time window PTW and / or a paging superframe PH for monitoring paging under the configuration of a first period parameter, according to the first period parameter;

[0162] The first cycle parameter includes at least one of a CN eDRX cycle, a RAN eDRX cycle, a CN DRX cycle, a RAN DRX cycle, and a default Paging Cycle cycle of a cell indicated by a system message.

[0163] Optionally, the processing module 401 is specifically used to determine, when the terminal device supports configuring the CN eDRX cycle but does not support configuring the RAN eDRX cycle, that the period for monitoring paging is a smaller value between the CN eDRX cycle and the ran-PagingCycle cycle, or a minimum value among the CN eDRX cycle, the ran-PagingCycle cycle and the defaultPagingCycle cycle.

[0164] Optionally, without considering the defaultPagingCycle period, the processing module 401 is specifically configured to:

[0169] If the RAN is not configured with the ran-PagingCycle period, the period of monitoring paging is determined to be the minimum value between the CNeDRX period and the defaultPagingCycle period.

[0170] Optionally, the processing module 401 is specifically used to determine, when the terminal device supports CN configuration of CN eDRX cycle and RAN configuration of RAN eDRX cycle, that the period for monitoring paging is at least one of the CN eDRX cycle, the RAN eDRX cycle, the CN DRX cycle, the RAN DRX cycle, and the default paging cycle defaultPagingCycle cycle.

[0171] Optionally, the processing module 401 is specifically configured to: if the CN configures the CN eDRX cycle and the RAN configures the RAN eDRX cycle, determine the period for monitoring paging to be a smaller value between the CN eDRX cycle and the RAN eDRX cycle.

[0172] Optionally, when the CN is configured with the CN eDRX cycle, the RAN is not configured with the RAN eDRX cycle, and the defaultPagingCycle cycle is not considered, the processing module 401 is specifically configured to:

[0173] If the RAN is configured with the ran-PagingCycle period, determining the period of monitoring Paging to be a smaller value between the CNeDRX period and the ran-PagingCycle period;

[0174] If the RAN is not configured with the ran-PagingCycle period, the period for monitoring Paging is determined to be the CNeDRX period.

[0175] Optionally, when the CN is configured with the CN eDRX cycle and the RAN is not configured with the RAN eDRX cycle, considering the defaultPagingCycle cycle, the processing module 401 is specifically configured to:

[0176] If the RAN is configured with the ran-PagingCycle cycle, determining the period of monitoring paging to be the minimum value among the CNeDRX cycle, the ran-PagingCycle cycle and the defaultPagingCycle cycle;

[0180] If the CN does not configure the CN DRX cycle, the period for monitoring paging is determined to be the minimum value between the defaultPagingCycle period and the RAN eDRX period.

[0181] Optionally, the terminal device further includes:

[0182] The transceiver module 402 is used to receive the first cycle parameter configured from a network device.

[0183] Optionally, the processing module 401 is further used to calculate the corresponding subframe PO according to the DRX cycle of the monitored paging and the identifier of the terminal device.

[0184] Corresponding to the method of at least one embodiment applied to a terminal device, the embodiment of the present application also provides one or more terminal devices. The terminal device of the embodiment of the present application can implement any one of the implementation modes of the above method. Figure 5 As shown in FIG. 1 , a schematic diagram of an embodiment of a terminal device in an embodiment of the present invention is shown. The terminal device is described by taking a mobile phone as an example, and may include: a radio frequency (RF) circuit 510, a memory 520, an input unit 530, a display unit 540, a sensor 550, an audio circuit 560, a wireless fidelity (WiFi) module 570, a processor 580, and a power supply 550. Among them, the RF circuit 510 includes a receiver 514 and a transmitter 512. Those skilled in the art can understand that Figure 5 The mobile phone structure shown in the figure does not constitute a limitation on the mobile phone, and may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0185] Combine the following Figure 5 A detailed introduction to the various components of the mobile phone:

[0186] The RF circuit 510 can be used for receiving and sending signals during information transmission or calls. In particular, after receiving the downlink information of the base station, it is sent to the processor 580 for processing; in addition, the designed uplink data is sent to the base station. Generally, the RF circuit 510 includes but is not limited to an antenna, at least one amplifier, a transceiver, a coupler, a low noise amplifier (LNA), a duplexer, etc. In addition, the RF circuit 510 can also communicate with the network and other devices through wireless communication. The above wireless communication can use any communication standard or protocol, including but not limited to the global system of mobile communication (GSM), general packet radio service (GPRS), code division multiple access (CDMA), wideband code division multiple access (WCDMA), long term evolution (LTE), email, short messaging service (SMS), etc.

[0187] The memory 520 can be used to store software programs and modules. The processor 580 executes various functional applications and data processing of the mobile phone by running the software programs and modules stored in the memory 520. The memory 520 can mainly include a program storage area and a data storage area, wherein the program storage area can store an operating system, an application required for at least one function (such as a sound playback function, an image playback function, etc.), etc.; the data storage area can store data created according to the use of the mobile phone (such as audio data, a phone book, etc.), etc. In addition, the memory 520 can include a high-speed random access memory, and can also include a non-volatile memory, such as at least one disk storage device, a flash memory device, or other volatile solid-state storage devices.

[0188] The input unit 530 can be used to receive input digital or character information, and to generate key signal input related to the user settings and function control of the mobile phone. Specifically, the input unit 530 may include a touch panel 531 and other input devices 532. The touch panel 531, also known as a touch screen, can collect the user's touch operation on or near it (such as the user's operation on the touch panel 531 or near the touch panel 531 using any suitable object or accessory such as a finger, stylus, etc.), and drive the corresponding connection device according to a pre-set program. Optionally, the touch panel 531 may include two parts: a touch detection device and a touch controller. Among them, the touch detection device detects the user's touch orientation, detects the signal brought by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device, converts it into contact coordinates, and then sends it to the processor 580, and can receive and execute commands sent by the processor 580. In addition, the touch panel 531 can be implemented in various types such as resistive, capacitive, infrared, and surface acoustic waves. In addition to the touch panel 531, the input unit 530 may also include other input devices 532. Specifically, the other input devices 532 may include but are not limited to one or more of a physical keyboard, function keys (such as volume control keys, switch keys, etc.), a trackball, a mouse, a joystick, etc.

[0189] The display unit 540 may be used to display information input by the user or information provided to the user and various menus of the mobile phone. The display unit 540 may include a display panel 541. Optionally, the display panel 541 may be configured in the form of a liquid crystal display (LCD), an organic light-emitting diode (OLED), or the like. Further, the touch panel 531 may cover the display panel 541. When the touch panel 531 detects a touch operation on or near it, it is transmitted to the processor 580 to determine the type of touch event. Subsequently, the processor 580 provides a corresponding visual output on the display panel 541 according to the type of touch event. Although in Figure 5 In the embodiment, the touch panel 531 and the display panel 541 are used as two independent components to realize the input and output functions of the mobile phone, but in some embodiments, the touch panel 531 and the display panel 541 can be integrated to realize the input and output functions of the mobile phone.

[0190] The mobile phone may also include at least one sensor 550, such as a light sensor, a motion sensor, and other sensors. Specifically, the light sensor may include an ambient light sensor and a proximity sensor, wherein the ambient light sensor may adjust the brightness of the display panel 541 according to the brightness of the ambient light, and the proximity sensor may turn off the display panel 541 and / or the backlight when the mobile phone is moved to the ear. As a type of motion sensor, the accelerometer sensor can detect the magnitude of acceleration in all directions (generally three axes), and can detect the magnitude and direction of gravity when stationary. It can be used for applications that identify the posture of the mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc.; as for other sensors that can be configured in the mobile phone, such as gyroscopes, barometers, hygrometers, thermometers, infrared sensors, etc., they will not be repeated here.

[0191] The audio circuit 560, the speaker 561, and the microphone 562 can provide an audio interface between the user and the mobile phone. The audio circuit 560 can transmit the received audio data to the speaker 561 after converting the received audio data into an electrical signal, which is converted into a sound signal for output; on the other hand, the microphone 562 converts the collected sound signal into an electrical signal, which is received by the audio circuit 560 and converted into audio data, and then the audio data is output to the processor 580 for processing, and then sent to another mobile phone through the RF circuit 510, or the audio data is output to the memory 520 for further processing.

[0192] WiFi is a short-range wireless transmission technology. The mobile phone can help users send and receive emails, browse web pages and access streaming media through the WiFi module 570. It provides users with wireless broadband Internet access. Figure 5A WiFi module 570 is shown, but it is understandable that it is not an essential component of the mobile phone and can be omitted as needed without changing the essence of the invention.

[0193] The processor 580 is the control center of the mobile phone. It uses various interfaces and lines to connect various parts of the entire mobile phone. By running or executing software programs and / or modules stored in the memory 520, and calling data stored in the memory 520, it executes various functions of the mobile phone and processes data, thereby monitoring the mobile phone as a whole. Optionally, the processor 580 may include one or more processing units; preferably, the processor 580 may integrate an application processor and a modem processor, wherein the application processor mainly processes the operating system, user interface, and application programs, and the modem processor mainly processes wireless communications. It is understandable that the above-mentioned modem processor may not be integrated into the processor 580.

[0194] The mobile phone also includes a power supply 590 (such as a battery) for supplying power to various components. Preferably, the power supply can be logically connected to the processor 580 through a power management system, so that the power management system can manage charging, discharging, power consumption management, etc. Although not shown, the mobile phone can also include a camera, a Bluetooth module, etc., which will not be described in detail here.

[0195] In this embodiment of the present invention, the processor 580 is configured to, for a terminal device in a radio resource control inactive RRC_INACTIVE state, if the terminal device does not use a paging time window PTW and / or a paging superframe PH for monitoring paging under the configuration of a first cycle parameter, determine a monitoring paging cycle according to the first cycle parameter;

[0196] The first cycle parameter includes at least one of a CN eDRX cycle, a RAN eDRX cycle, a CN DRX cycle, a RAN DRX cycle, and a default Paging Cycle cycle of a cell indicated by a system message.

[0197] Optionally, the processor 580 is specifically configured to determine, when the terminal device supports configuring the CN eDRX cycle but does not support configuring the RAN eDRX cycle, that the period for monitoring paging is a smaller value between the CN eDRX cycle and the ran-PagingCycle cycle, or a minimum value among the CN eDRX cycle, the ran-PagingCycle cycle and the defaultPagingCycle cycle.

[0198] Optionally, without considering the defaultPagingCycle period, the processor 580 is specifically configured to:

[0205] Optionally, the processor 580 is specifically configured to: if the CN configures the CN eDRX cycle and the RAN configures the RAN eDRX cycle, determine the period for monitoring paging to be a smaller value between the CN eDRX cycle and the RAN eDRX cycle.

[0207] If the RAN is configured with the ran-PagingCycle period, determining the period of monitoring Paging to be a smaller value between the CNeDRX period and the ran-PagingCycle period;

[0208] If the RAN is not configured with the ran-PagingCycle period, the period for monitoring Paging is determined to be the CNeDRX period.

[0209] Optionally, when the CN is configured with the CN eDRX cycle and the RAN is not configured with the RAN eDRX cycle, considering the defaultPagingCycle cycle, the processor 580 is specifically configured to:

[0210] If the RAN is configured with the ran-PagingCycle cycle, determining the period of monitoring paging to be the minimum value among the CNeDRX cycle, the ran-PagingCycle cycle and the defaultPagingCycle cycle;

[0211] If the RAN is not configured with the ran-PagingCycle period, the period of monitoring paging is determined to be the minimum value between the CNeDRX period and the defaultPagingCycle period.

[0212] Optionally, when the CN is not configured with the CN eDRX cycle and the RAN is configured with the RAN eDRX cycle, considering the defaultPagingCycle cycle, the processor 580 is specifically configured to:

[0213] If the CN is configured with a CN DRX cycle, determining the period of monitoring paging to be the smallest value among the CN DRX cycle, the defaultPagingCycle cycle and the RAN eDRX cycle;

[0214] If the CN does not configure the CN DRX cycle, the period for monitoring paging is determined to be the minimum value between the defaultPagingCycle period and the RAN eDRX period.

[0215] Optionally, the RF circuit 510 is used to receive the first cycle parameter configured from a network device.

[0216] Optionally, the processor 580 is further used to calculate the corresponding subframe PO according to the DRX cycle of the monitored paging and the identifier of the terminal device.
