[0002] In a Long Term Evolution (LTE) system, when a user equipment (UE) in the radio resource control inactive (RRC_INACTIVE) state is configured for extended discontinuous reception (eDRX) by higher layers, the current standard defines the UE's behavior for monitoring paging during the paging time window (PTW) and outside the PTW. Among the eDRX period values ​​supported by LTE, if the eDRX period is 10.24 seconds or greater, the PTW is used for paging monitoring. If the eDRX period is equal to 5.12 seconds, the PTW is not used for paging monitoring. When the eDRX period is set to 5.12 seconds, the behavior of the UE monitoring paging in the RRC_IDLE state is clear, but the behavior of the UE monitoring paging in the RRC_IDLE state is unclear. For example, in this case, it is unclear how the UE should determine the DRX period T for monitoring paging. Summary of the Invention

[0015] The following describes the technical solutions of the embodiments of the present disclosure with reference to the drawings of the embodiments of the present disclosure. It is obvious that the described embodiments are only a part of the embodiments of the present disclosure, but not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments that can be obtained by a person skilled in the art without any creative efforts shall fall within the protection scope of the present disclosure.

[0016] As shown below, we first provide a brief explanation of terminology relevant to the embodiments of the present disclosure.

[0017] 1. Radio Resource Control (RRC) state of the user equipment (UE) In Long Term Evolution (LTE) and 5G systems, there are three RRC protocol states: RRC_IDLE, RRC_INACTIVE, and RRC_CONNECTED.

[0018] RRC_IDLE: Mobility is UE-based 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.

[0019] RRC_INACTIVE: Mobility is UE-based cell selection / reselection, there is a CN-NR (New Radio) connection, the UE AS context resides in a base station, paging is triggered by the Radio Access Network (RAN), the RAN-based paging area is managed by the RAN, and the UE location known to the network is at the RAN-based paging area level.

[0020] RRC_CONNECTED: An RRC connection exists, and the base station and UE have a UE AS context. The UE location known to the network is specific to the cell level. Mobility is controlled by the network. Data can be transmitted between the UE and the base station.

[0021] 2. 5G NR Paging Mechanism The main function of paging is to enable the network to page the UE by a paging message when the UE is in RRC_IDLE or RRC_INACTIVE state, or to notify the UE of system message changes or earthquake / tsunami / public warning information by a short message (applies to all RRC states, including the UE's connected state).

[0022] Paging includes a Physical Downlink Control Channel (PDCCH) scrambled by a Paging Radio Network Temporary Identifier (P-RNTI) and a Physical Downlink Share Channel (PDCCH) scheduled by the PDCCH. The paging message is transmitted on the PDSCH, and the short message is 8 bits long on the PDCCH.

[0023] A UE in RRC_IDLE or RRC_INACTIVE state has no other data communication between the UE and the network. Therefore, to save power, the UE can monitor the paging channel discontinuously, i.e., adopts a paging DRX (Discontinuous Reception) mechanism. In the paging DRX mechanism, the UE only needs to monitor paging during one PO in each DRX cycle. A PO is a period for monitoring a series of PDCCHs and can consist of multiple time slots. There is also the concept of a paging frame (PF). A PF refers to one radio frame (fixed at 10 ms), which can include multiple POs or the starting positions of multiple POs.

[0024] The paging DRX cycle is determined jointly by the common cycle in the system broadcast and the dedicated cycle set by higher layer signaling (Non-access Stratum (NAS) signaling), and the UE determines the smallest cycle of the two as its paging cycle. From the network's perspective, one paging DRX cycle can have multiple POs, and the location where a UE monitors the PO is related to the UE's identity (ID). Specifically, the PF and PO in one paging DRX of a UE are determined as follows (TS 38.304):

[0025] The system frame number (SFN) of the PF is determined by the following formula: (SFN+PF_offset) mod T=(T div N)*(UE_ID mod N)

[0026] The index (i_s) of a PO in a certain PF is determined by the following formula. i_s = floor (UE_ID / N) mod Ns

[0027] The above parameters are explained as follows: T: The DRX cycle at which the UE receives paging. The network broadcasts one default DRX cycle. If the RRC / upper layer configures a UE-dedicated DRX cycle for the UE, the smallest value of the DRX cycle broadcast by the network and the UE-dedicated DRX cycle configured by the RRC / upper layer is used as the DRX cycle for the UE. If the RRC / upper layer does not configure a UE-dedicated DRX cycle for the UE, the DRX cycle broadcast by the network is used as the DRX cycle for the UE. N: The number of PFs included in one DRX cycle. Ns: The number of POs included in one PF. PF_offset: The offset in the time domain for determining the PF. UE_ID:5G-S-TMSI mod 1024.

[0028] The settings for the above parameters are as follows: TIFF0007744984000001.tif201170

[0029] Based on the above formula, the UE can know the position of the PF in the paging DRX cycle and the index of the PO. As specified in TS 38.304, a PO consists of multiple PDCCH monitoring occasions, and one PO includes X PDCCH monitoring occasions, where X is equal to the number of synchronization signal blocks (SSBs) broadcast in a master information block (MIB) that are actually transmitted.

[0030] After knowing the PF, the index of the PO, and the number of PDCCH monitoring occasions in the PO, the UE only needs to determine the starting position of the first PDCCH monitoring occasion in the PO through related configuration parameters. The starting position can be configured by higher layer signaling or can be obtained based on the index of the PO. The UE performs blind detection of the paging message based on the determined PO.

[0031] 3. Long Term Evolution (LTE) paging mechanism In the LTE system, a UE in the RRC_IDLE state or the RRC_INACTIVE state also employs a paging DRX mechanism. Similar to the NR system, the paging DRX mechanism requires the UE to monitor paging during one PO within each DRX cycle. The LTE system also defines the concepts of PF and PO, but differs from the NR system in that in the LTE system, a PO corresponds to one subframe within a PF.

[0032] Similar to the NR system, in the LTE system, for a UE in RRC_IDLE state or RRC_INACTIVE state, the UE calculates its PO based on parameters such as UE ID and T, where T represents the DRX period during which the UE receives paging, and is determined as follows:

[0033] For a UE in RRC_IDLE state, if a higher layer configures the UE for extended DRX (eDRX) and the configured eDRX cycle is 5.12 seconds, the value of T is 5.12 seconds. Otherwise, if a higher layer configures a UE-dedicated DRX cycle for the UE, the smallest value of the DRX cycle broadcast by the network and the UE-dedicated DRX cycle configured by the higher layer is set as T. If a higher layer does not configure a UE-dedicated DRX cycle for the UE, the DRX cycle broadcast by the network is set as T.

[0034] For a UE in RRC_INACTIVE state, if higher layers have not configured eDRX for the UE, the smallest of the DRX period broadcast by the network and the UE-dedicated DRX period configured by RRC / higher layers shall be defined as T. Otherwise, if higher layers have configured eDRX for the UE, the smallest of the DRX period broadcast by the network and the UE-dedicated DRX period configured by RRC / higher layers shall be defined as T during the Paging Time Window (PTW), and the UE-dedicated DRX period configured by RRC outside the PTW shall be defined as T.

[0035] 4. LTE eDRX Mechanism Considering that Narrow Band Internet of Things (NB-IoT) and enhanced machine type communication (eMTC) terminals have a single business type and low business volume, these terminals are in an unconnected state most of the time. At the same time, considering that the business of these terminals is not sensitive to delay requirements, in order to further save power when these terminals are in an unconnected state, LTE introduces an eDRX mechanism for these types of terminals, which can support a larger paging cycle, i.e., the paging cycle is larger than 256 SFNs. In LTE, the minimum value of the eDRX cycle set by higher layers is 5.12 seconds.

[0036] For a UE configured for eDRX, if the UE's eDRX period is 5.12 seconds, the UE calculates its corresponding PO based on T=5.12 seconds. If the UE's eDRX period is equal to or greater than one Hyper System Frame Number (H-SFN), the UE monitors the PDCCH scrambled with the P-RNTI in its PO during the PTW time window within one eDRX period. Here, the PTW is dedicated to the UE and is determined based on the paging hyperframe (PH), the start time PTW_start, and the end time PTW_end in the PH.

[0037] PH is an H-SFN that satisfies the following conditions: H-SFN mod TeDRX,H=(UE_ID_H mod TeDRX,H)

[0038] Here, UE_ID_H is obtained based on the hash ID, and TeDRX,H is the eDRX period in units of hyperframes, and is set by the AMF.

[0039] PTW_start is the starting radio frame number of the PTW and is an SFN that satisfies the following conditions: SFN = 256* ieDRXieDRX = floor(UE_ID_H / TeDRX,H) mod 4

[0040] PTW_end is the end radio frame number of the PTW and is an SFN that satisfies the following conditions: SFN = (PTW_start + L*100 - 1) mod 1024

[0041] Here, L is the window length of the PTW and is set by the Access and Mobility Management Function (AMF).

[0042] 5. NR RedCap (reduced capability) eDRX mechanism In the R17 NR work project, the 3GPP RAN meeting agreed on a project (RP-193238) to study low-capability NR terminals, where one of the project objectives is to: TIFF0007744984000002.tif41170

[0043] That is, by introducing an eDRX mechanism in idle or inactive state for low-capability NR terminals, the purpose of saving terminal power and extending battery life is achieved.

[0044] Currently, NR RedCap is in the SI phase, and the two most recent RAN2 meetings (RAN2#111e and RAN2#112e) have formed the following conclusions for RedCap's eDRX mechanism:

[0045] For the RRC_IDLE state, it is possible to study whether it is necessary to extend the DRX period to greater than 2621.44 s as a baseline and support a larger eDRX period (e.g., 10485.76 s).For the RRC_INACTIVE state, it is possible to consider whether it is necessary to extend the DRX period to 10.24 s as a baseline and support a larger eDRX period in the next meeting.

[0046] RAN2 needs to study whether it needs to support values ​​smaller than 5.12 seconds for the eDRX period in RRC_IDLE and RRC_INACTIVE states.

[0047] For UEs in RRC_IDLE and RRC_INACTIVE states, if the maximum DRX cycle that can be supported exceeds 10.24 seconds, the LTE eDRX mechanism (i.e., using PTW, PH, etc.) with an eDRX cycle greater than 10.24 seconds is used as the baseline. For UEs in RRC_IDLE and RRC_INACTIVE states, if the eDRX cycle is less than 10.24 seconds, paging monitoring does not use PTW, PH, etc.

[0048] For UEs in RRC_IDLE and RRC_INACTIVE states, if the eDRX period is equal to 10.24 s, it is basically assumed that PTW and PH are not used, but other solutions are not excluded.

[0049] On the other hand, in an LTE system, when a higher layer configures eDRX for a UE in RRC_INACTIVE state, the current standard defines two behaviors: one in which the UE monitors paging during the PTW period, and the other in which the UE monitors paging outside the PTW period. Among the eDRX cycle values ​​supported by LTE, if the eDRX cycle is 10.24 seconds or longer, paging monitoring uses the PTW. If the eDRX cycle is equal to 5.12 seconds, paging monitoring does not use the PTW. When the eDRX cycle is set to 5.12 seconds, the behavior of the UE monitoring paging in RRC_IDLE state is clear, but the behavior of the UE monitoring paging in RRC_IDLE state is unclear. For example, in this case, it is unclear how to determine the DRX cycle T for the UE to monitor paging.

[0050] On the other hand, in an NR system, based on the conclusions of the current RAN2 meeting for the RedCap SI phase, for RedCap UEs in the RRC_INACTIVE state, there is currently no conclusion as to whether the RRC_INACTIVE state supports a DRX cycle greater than 10.24 seconds. In other words, it has not yet been decided whether to directly extend the value range of the current parameter ran-PagingCycle to extend the network-configured RAN DRX cycle, or to introduce a new parameter RAN eDRX cycle to accommodate the extended DRX cycle setting.

[0051] Also, as with UEs in LTE systems, when the eDRX cycle set by the higher layer and the DRX cycle / eDRX cycle set by the RRC (when the RAN eDRX cycle setting parameter is introduced) are both smaller than (or equal to) 10.24 s, that is, paging monitoring does not use PTW, it is also a problem to be solved how the UE determines the DRX cycle for monitoring paging in such a case.

[0052] The technical solutions of the embodiments of the present disclosure can be applied to various communication systems. For example, Global System of Mobile communication (GSM) systems, Code Division Multiple Access (CDMA) systems, Wideband Code Division Multiple Access (WCDMA) systems, General Packet Radio Service (GPRS), Long Term Evolution (LTE) systems, Advanced Long Term Evolution (LTE-A) systems, New Radio (NR) systems, evolutions of NR systems, LTE-based access to unlicensed spectrum (LTE-U) systems, NR-based access to unlicensed spectrum (NR-U) systems, Non-Terrestrial Networks (NTN) systems, Universal Mobile Telecommunication System (UMTS), and Wireless Local Area Networks (WLAN). Networks, Wireless Fidelity (WiFi), 5th-Generation (5G) systems, or other communication systems.

[0053] Generally, conventional communication systems support a limited number of connections and are easy to implement. However, with the development of communication technologies, mobile communication systems support not only conventional communication but also, for example, device-to-device (D2D) communication, machine-to-machine (M2M) communication, machine-type communication (MTC), vehicle-to-vehicle (V2V) communication, or vehicle-to-everything (V2X) communication, and embodiments of the present disclosure can also be applied to these communication systems.

Wearable devices are portable devices that are worn directly or integrated into a user's clothing or accessories. Wearable devices are not simply hardware devices; they achieve powerful functions through software support, data interaction, and cloud interaction. In a broad sense, wearable smart devices include fully functional, large-sized devices that can achieve full or partial functions without relying on a smartphone, such as smart watches and smart glasses, as well as devices that simply focus on certain application functions and require use in conjunction with other devices, such as smartphones, such as smart handhelds and smart jewelry that monitor various vital signs.

The communication system may include network devices, which may be devices that communicate with terminal devices (also referred to as communication terminals or terminals). The network devices may provide communication coverage in a specific geographical area and communicate with terminal devices located within the coverage area. FIG. 1 exemplarily illustrates one network device and two terminal devices. Alternatively, the communication system may include multiple network devices, and the coverage range of each network device may include other numbers of terminal devices, and the embodiment of the present disclosure is not limited thereto. Alternatively, the communication system may further include other network entities, such as a network controller and a mobility management entity, and the embodiment of the present disclosure is not limited thereto.

[0065] Here, the network equipment may include access network equipment and core network equipment. That is, the wireless communication system further includes multiple core networks for communicating with the access network equipment. The access network equipment may be an evolutionary base station (eNB or e-NodeB) in a Long Term Evolution (LTE) system, a Next Radio (NR) system, or an Authorized Auxiliary Access Long Term Evolution (LAA-LTE) system, such as a macro base station, a micro base station (also called a "small base station"), a pico base station, an access point (AP), a transmission point (TP), or a new generation Node B (gNodeB).

[0066] As can be understood, in the embodiments of the present disclosure, a device having a communication function in a network / system can be referred to as a communication device. Taking the communication system shown in FIG. 1 as an example, the communication device can include a network device and a terminal device having a communication function. The network device and the terminal device can be specific devices described in the embodiments of the present disclosure and will not be repeated here. The communication device can also include other devices in the communication system, such as other network entities such as a network controller and a mobility management entity, and the embodiments of the present disclosure are not limited thereto.

[0067] The following will further describe the technical solution of the present disclosure in the form of an embodiment. As shown in Figure 2, Figure 2 is a schematic diagram of an embodiment of a paging cycle determination method in an embodiment of the present disclosure, which may include the following steps:

[0068] In step 201, the terminal device receives the first periodicity parameter set by the network device.

[0069] Here, 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 cell default paging cycle (defaultPagingCycle) indicated by a system message.

[0070] In step 202, if the terminal device is in a radio resource control inactive (RRC_INACTIVE) state, and if the terminal device monitors paging without using a paging time window (PTW) and / or a paging hyperframe (PH) when a first periodicity parameter is set, the terminal device determines the period for monitoring paging based on the first periodicity parameter.

[0071] In step 203, the terminal device calculates a corresponding subframe PO based on the DRX period for monitoring the paging and the identifier of the terminal device.

[0072] In the following, the step of the terminal device determining the period for monitoring paging based on the first period parameter will be described in two ways.

[0073] Realization method 1 If the terminal device supports setting the CN eDRX cycle but does not support setting the RAN eDRX cycle, it determines that the cycle for monitoring paging is the smaller of the CN eDRX cycle and the ran-PagingCycle cycle, or the smallest of the CN eDRX cycle, the ran-PagingCycle cycle, and the defaultPagingCycle cycle.

[0074] It can be understood that the CN only supports configuring the CN eDRX cycle through NAS signaling, and the RAN does not support configuring the RAN eDRX cycle through RRC signaling (e.g., when the maximum configurable RAN paging cycle of the base station does not exceed 10.24 seconds). If the network configures the UE with a CN eDRX cycle and does not use PTW and / or PH for the configured CN eDRX cycle, the UE in RRC_INACTIVE state determines that the DRX cycle it monitors for paging is the smaller of the CN eDRX cycle and ran-PagingCycle, or the smallest of the CN eDRX cycle, ran-PagingCycle, and defaultPagingCycle.

[0075] 1. Optionally, the step of the terminal device receiving the first periodicity parameters set by the network device, i.e., the DRX-related parameters and eDRX-related parameters for determining the paging period, may include the following cases:

[0076] a) Receive DRX parameters including the UE-dedicated CN DRX period set by the NAS message from the CN.

[0077] b) Receive eDRX parameters including the eDRX period CN eDRX period set by the NAS message from the CN.

[0078] c) Receive the cell default paging cycle indicated by the system message.

[0079] d) Receive an RRC release message from the RAN to instruct the UE to enter the RRC_INACTIVE state, and at the same time, set a UE-dedicated RAN paging cycle (ran-PagingCycle).

[0080] 2. Optionally, the step of the terminal device determining the period for monitoring paging based on the first period parameter can be described in the following cases:

[0081] case one When the default PagingCycle period is not taken into consideration, the step of determining a period for the terminal device to monitor paging based on the first period parameter may include the following cases.

[0082] a) If the RAN configures the ran-PagingCycle period, the terminal device determines that the period for monitoring the paging is the smaller of the CN eDRX period and the ran-PagingCycle period.

[0083] For example, if the RAN configures the UE with a ran-PagingCycle period, the paging monitoring period T=min{CN eDRX period, ran-PagingCycle}.

[0084] b) If the RAN does not configure the ran-PagingCycle period, the terminal device determines that the period for monitoring the paging is the CN eDRX period.

[0085] For example, if the RAN does not configure ran-PagingCycle for the UE, the paging monitoring cycle T=CN eDRX cycle.

[0086] Case 2 When the default PagingCycle period is taken into consideration, the step of determining a period for the terminal device to monitor paging based on the first period parameter may include the following cases.

[0087] a) If the RAN configures the ran-PagingCycle period, the terminal device determines that the period for monitoring the paging is the smallest of the CN eDRX period, the ran-PagingCycle period, and the defaultPagingCycle period.

[0088] For example, if the RAN configures the ran-PagingCycle period for the UE, the paging monitoring period T=min{CN eDRX period, ran-PagingCycle period, defaultPagingCycle period}.

[0089] b) If the RAN does not configure the ran-PagingCycle period, the terminal device determines that the period for monitoring the paging is the smaller of the CN eDRX period and the defaultPagingCycle period.

[0090] For example, if the RAN does not configure the ran-PagingCycle period for the UE, the paging monitoring period T=min{CN eDRX period, defaultPagingCycle period}.

[0091] For example, for the above case 1 and case 2, as shown in FIG. 3A, FIG. 3A is a schematic diagram of a terminal device in an embodiment of the present disclosure determining a period for monitoring paging.

[0092] 3. Optionally, for a UE in RRC_INACTIVE state, the UE calculates its corresponding PO based on the UE ID, paging period T, etc.

[0093] Realization method 2 If the terminal device supports setting a CN eDRX cycle for the CN and setting a RAN eDRX cycle for the RAN, it determines that the cycle 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 defaultPagingCycle cycle.

[0094] It can be understood that the NAS supports configuring CN eDRX and the RRC supports configuring RAN eDRX simultaneously (e.g., when the maximum value of the RAN paging cycle that the base station can configure is greater than 10.24 seconds). If the network configures the CN eDRX cycle and / or the RAN eDRX cycle for the UE and does not use PTW and / or PH for the configured CN eDRX cycle and the RAN eDRX cycle (e.g., for a RedCap UE, the CN eDRX cycle configured by the CN and the RAN eDRX cycle configured by the base station are both 5.12 seconds), the UE in RRC_INACTIVE determines the DRX cycle at which the UE monitors paging based on at least one of the configured CN eDRX cycle, RAN eDRX cycle, CN DRX cycle, RAN DRX cycle, and the cell default paging cycle indicated by a system message.

[0095] 1. Optionally, the step of the terminal device receiving the first periodicity parameters set by the network device, i.e., the DRX-related parameters and eDRX-related parameters for determining the paging period, may include the following cases:

[0096] a) Receive DRX parameters including the UE-dedicated CN DRX period set by the NAS message from the CN.

[0097] b) Receive eDRX parameters including the eDRX period CN eDRX period set by the NAS message from the CN.

[0098] c) Receive the cell default paging cycle indicated by the system message.

[0099] d) Receive an RRC release message from the RAN to instruct the UE to enter the RRC_INACTIVE state, and at the same time, set a UE-dedicated RAN paging cycle (ran-PagingCycle) and a UE-dedicated RAN eDRX cycle.

[0100] 2. Optionally, the step of the terminal device determining the period for monitoring paging based on the first period parameter can be described in the following cases:

[0101] case one If the CN sets the CN eDRX cycle and the RAN sets the RAN eDRX cycle, the terminal device determines that the cycle for monitoring the paging is the smaller of the CN eDRX cycle and the RAN eDRX cycle.

[0102] 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 paging monitoring cycle T = min {CN eDRX cycle, RAN eDRX cycle}. For the above case 1, as shown in Figure 3B, Figure 3B is another schematic diagram of a terminal device in an embodiment of the present disclosure determining a paging monitoring cycle.

[0103] Case 2 When the CN configures the CN eDRX cycle, the RAN does not configure the RAN eDRX cycle, and the default PagingCycle cycle is not taken into consideration, the step of the terminal device determining the cycle for monitoring paging based on the first cycle parameter includes the following cases:

[0104] a) If the RAN configures the ran-PagingCycle period, the terminal device determines that the period for monitoring the paging is the smaller of the CN eDRX period and the ran-PagingCycle period.

[0105] For example, if the RAN configures the ran-PagingCycle period for the UE through RRC signaling, the paging monitoring period T=min{CN eDRX period, ran-PagingCycle}.

[0106] b) If the RAN does not configure the ran-PagingCycle period, the terminal device determines that the period for monitoring the paging is the CN eDRX period.

[0107] For example, if the RAN does not configure the ran-PagingCycle period for the UE through RRC signaling, the paging monitoring period T=CN eDRX period.

[0108] Case 3 When the CN configures the CN eDRX cycle, the RAN does not configure the RAN eDRX cycle, and the default PagingCycle cycle is taken into consideration, the step of the terminal device determining a cycle for monitoring paging based on the first cycle parameter includes the following cases:

[0109] a) If the RAN configures the ran-PagingCycle period, the terminal device determines that the period for monitoring the paging is the smallest of the CN eDRX period, the ran-PagingCycle period, and the defaultPagingCycle period.

[0110] For example, if the RAN configures the ran-PagingCycle period in the UE through RRC signaling, the paging monitoring period T=min{CN eDRX period, ran-PagingCycle period, defaultPagingCycle period}.

[0111] b) If the RAN does not configure the ran-PagingCycle period, the terminal device determines that the period for monitoring the paging is the smaller of the CN eDRX period and the defaultPagingCycle period.

[0112] For example, if the RAN does not configure the ran-PagingCycle period for the UE through RRC signaling, the paging monitoring period T=min{CN eDRX period, defaultPagingCycle period}.

[0113] For the above cases 2 and 3, as shown in FIG. 3C, FIG. 3C is another schematic diagram of a terminal device in an embodiment of the present disclosure determining a period for monitoring paging.

[0114] Case 4 When the CN does not configure the CN eDRX cycle, the RAN configures the RAN eDRX cycle, and takes the default PagingCycle cycle into consideration, the step of the terminal device determining a cycle for monitoring paging based on the first cycle parameter includes the following cases:

[0115] a) If the CN sets a CN DRX cycle, the terminal device determines that the cycle for monitoring the paging is the smallest of the CN DRX cycle, the default PagingCycle cycle, and the RAN eDRX cycle.

[0116] For example, if the CN configures a CN DRX cycle for the UE, the cycle for monitoring paging is T=min{CN DRX cycle, defaultPagingCycle cycle, RAN eDRX cycle}.

[0117] b) If the CN does not set a CN DRX cycle, the terminal device determines that the cycle for monitoring the paging is the smaller of the default PagingCycle cycle and the RAN eDRX cycle.

[0118] 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}. For the above case 4, as shown in Figure 3D, Figure 3D is another schematic diagram of a terminal device in an embodiment of the present disclosure determining a paging monitoring cycle.

[0119] 3. Optionally, a UE in RRC_INACTIVE state calculates its corresponding PO based on the UE ID, paging period T, etc.

[0120] It should be noted that the period for monitoring paging may be referred to as a paging period for short.

[0121] In an embodiment of the present disclosure, a method for determining a paging cycle for a UE in an RRC_INACTIVE state is disclosed. When a terminal device in a radio resource control inactive (RRC_INACTIVE) state monitors paging without using a paging time window (PTW) and / or a paging hyperframe (PH) when a first cycle parameter is configured, the terminal device determines a cycle for monitoring paging based on the first cycle parameter, where 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 cell default paging (defaultPagingCycle) cycle indicated by a system message. This method clarifies the behavior of a UE monitoring paging when the UE is in an RRC_INACTIVE state, has an eDRX cycle configured, and does not use a PTW and / or a PH when the eDRX cycle is configured. This ensures paging performance while taking into consideration the energy saving needs of the terminal.

[0122] Specifically, if the CN only supports configuring CN eDRX and the RAN does not support configuring RAN eDRX, the UE in RRC_INACTIVE state determines the DRX cycle it will monitor for paging to be the smaller of the CN eDRX cycle and ran-PagingCycle, or the smallest of the CN eDRX cycle, ran-PagingCycle, and defaultPagingCycle. If the CN supports configuring CN eDRX and the RAN supports configuring RAN eDRX simultaneously, the UE in RRC_INACTIVE state determines the DRX cycle it will monitor for paging based on at least one of the configured CN eDRX cycle, RAN eDRX cycle, CN DRX cycle, RAN DRX cycle, and a cell default paging cycle indicated by a system message.

[0123] 4, which is a schematic diagram of an embodiment of a terminal device in an embodiment of the present disclosure. The terminal device may include a processing module 401.

[0124] The processing module 401 is for determining a period for monitoring paging based on a first period parameter when the terminal device is in a radio resource control inactive (RRC_INACTIVE) state and the terminal device monitors paging without using a paging time window (PTW) and / or a paging hyperframe (PH) when a first period parameter is set.

[0125] 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 cell default paging (defaultPagingCycle) cycle indicated by a system message.

[0126] Optionally, the processing module 401 is specifically configured to determine that, when the terminal device supports setting a CN eDRX cycle but does not support setting a RAN eDRX cycle, the cycle for monitoring paging is the smaller of the CN eDRX cycle and the ran-PagingCycle cycle, or the smallest of the CN eDRX cycle, the ran-PagingCycle cycle, and the defaultPagingCycle cycle.

[0127] Optionally, if the default PagingCycle period is not taken into account, the processing module 401 specifically: If the RAN configures the ran-PagingCycle period, determining that the period for monitoring the paging is the smaller of the CN eDRX period and the ran-PagingCycle period; If the RAN does not configure the ran-PagingCycle period, it determines that the period for monitoring the paging is the CN eDRX period.

[0129] Optionally, the processing module 401 is specifically for determining, when the terminal device supports setting a CN eDRX cycle of a CN and setting a RAN eDRX cycle of a RAN, that the cycle 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 defaultPagingCycle cycle.

[0130] Optionally, the processing module 401 is specifically for determining that, when a CN sets the CN eDRX cycle and a RAN sets the RAN eDRX cycle, the cycle for monitoring paging is the smaller one of the CN eDRX cycle and the RAN eDRX cycle.

[0131] Optionally, if the CN configures the CN eDRX cycle, and the RAN does not configure the RAN eDRX cycle, and does not consider the default PagingCycle cycle, the processing module 401 specifically: If the RAN configures the ran-PagingCycle period, determining that the period for monitoring the paging is the smaller of the CN eDRX period and the ran-PagingCycle period; If the RAN does not configure the ran-PagingCycle period, it determines that the period for monitoring the paging is the CN eDRX period.

[0132] Optionally, if the CN configures the CN eDRX cycle, and the RAN does not configure the RAN eDRX cycle, and takes the default PagingCycle cycle into consideration, the processing module 401 specifically: If the RAN configures the ran-PagingCycle period, determining that the period for monitoring paging is the smallest of the CN eDRX period, the ran-PagingCycle period, and the defaultPagingCycle period; If the RAN does not configure the ran-PagingCycle period, the period for monitoring the paging is determined to be the smaller of the CN eDRX period and the defaultPagingCycle period.

[0133] Optionally, if the CN does not configure the CN eDRX cycle, and the RAN configures the RAN eDRX cycle, and takes the default PagingCycle cycle into consideration, the processing module 401 specifically: If the CN configures a CN DRX cycle, determining that the cycle for monitoring the paging is the smallest of the CN DRX cycle, the default PagingCycle cycle, and the RAN eDRX cycle; When the CN does not set a CN DRX cycle, the cycle for monitoring the paging is determined to be the smaller of the default PagingCycle cycle and the RAN eDRX cycle.

[0134] Optionally, the terminal device further comprises: The network device includes a transceiver module 402 for receiving the first periodicity parameter set by the network device.

[0135] Optionally, the processing module 401 is further for calculating a corresponding subframe PO according to the DRX period for monitoring paging and the identifier of the terminal device.

[0136] Corresponding to the method of the embodiment applied to at least one terminal device described above, the embodiment of the present disclosure further provides one or more types of terminal devices. The terminal device of the embodiment of the present disclosure can implement any implementation of the method described above. As shown in FIG. 5, FIG. 5 is a schematic diagram of an embodiment of a terminal device of the embodiment of the present disclosure. The terminal device is described using a mobile phone as an example, and may include components such as 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. Here, the RF circuit 510 includes a receiver 514 and a transmitter 512. It should be understood by those skilled in the art that the structure of the mobile phone shown in FIG. 5 is not limited to a mobile phone and may include more or fewer components than those shown, a specific combination of components, or a different component arrangement.

[0137] Below, we will combine Figure 5 to introduce each component of the mobile phone in detail.

[0138] The RF circuitry 510 may be used for receiving and transmitting signals during message transmission or call transmission, particularly for receiving downlink information from a base station and then transmitting it to the processor 580 for processing. It also transmits data designated for uplink transmission to the base station. Typically, the RF circuitry 510 includes, but is not limited to, an antenna, at least one amplifier, a receiver / transmitter, a coupler, a low-noise amplifier (LNA), and a duplexer. The RF circuitry 510 may also communicate with networks and other devices via wireless communications. The wireless communications may use any communication standard or protocol, including, but not limited to, global system of mobile communications (GSM), general packet radio service (GPRS), code division multiple access (CDMA), wideband code division multiple access (WCDMA), long term evolution (LTE), email, and short messaging service (SMS).

[0139] The memory 520 may be configured to store software programs and modules. The processor 580 executes the software programs and modules stored in the memory 520 to perform various functional applications and data processing for the mobile phone. The memory 520 may primarily include a memory program area and a memory data area. The memory program area may store an operating system, application programs necessary for at least one function (e.g., sound playback, image playback, etc.), and the memory data area may store data generated based on the use of the mobile phone (e.g., audio data, phone book, etc.). The memory 520 may also include high-speed random access memory and non-volatile memory, such as at least one disk storage device, flash memory device, or other volatile solid-state storage device.

[0140] The input unit 530 may receive input numeric or character information and generate key signal inputs related to 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 a user's touch operation on or near the touch panel 531 (e.g., a user's operation on or near the touch panel 531 using any suitable object or accessory, such as a finger, a touch pen, etc.) and drive a corresponding connected device based on a preset program. Optionally, the touch panel 531 may include two parts: a touch detection device and a touch controller. Here, the touch detection device detects the user's touch direction, detects a signal from the touch operation, and transmits the signal to the touch controller. The touch controller receives touch information from the touch detection device, converts it into contact coordinates, transmits it to the processor 580, and can receive and execute instructions transmitted from the processor 580. The touch panel 531 can be realized using various types of touch sensors, such as a resistive type, a capacitive type, an infrared type, and a surface acoustic wave type. In addition to the touch panel 531, the input unit 530 may further 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 (e.g., volume control buttons, switch buttons, etc.), a trackball, a mouse, and an operation stick.

[0141] The display unit 540 may be used to display information entered by or provided to a user, as well as various menus of the mobile phone. The display unit 540 may include a display panel 541, which may optionally be configured using a liquid crystal display (LCD), an organic light-emitting diode (OLED), or the like. Furthermore, a touch panel 531 may cover the display panel 541, and after the touch panel 531 detects a touch operation on or near the display panel 541, the touch panel 531 transmits the detected touch operation to the processor 580, thereby determining the type of touch event. The processor 580 then provides a corresponding visual output on the display panel 541 based on the type of touch event. In FIG. 5 , the touch panel 531 and the display panel 541 are two independent components that realize the input and output functions of the mobile phone. However, in some embodiments, the touch panel 531 and the display panel 541 may be integrated to realize the input and output functions of the mobile phone.

[0142] The mobile phone may further include at least one type of sensor 550, such as a light sensor, a motion sensor, or other sensors. Specifically, the light sensor may include an ambient light sensor and a proximity sensor. Here, the ambient light sensor can adjust the brightness of the display panel 541 based on the brightness of the ambient light, and the proximity sensor can turn off the display panel 541 and / or the backlight when the mobile phone is moved closer to the ear. As a type of motion sensor, an accelerometer sensor can detect the magnitude of acceleration in each direction (generally, three axes) and can detect the magnitude and direction of gravity when the mobile phone is stationary. This may be used for applications that identify the mobile phone's orientation (e.g., horizontal / vertical screen switching, related games, magnetometer orientation calibration), vibration identification-related functions (e.g., pedometer, tap), etc. Other sensors that may be configured in the mobile phone, such as a gyroscope, barometer, hygrometer, thermometer, and infrared sensor, will not be repeated here.

[0143] The audio circuit 560, speaker 561, and microphone 562 can provide an audio interface between the user and the mobile phone. The audio circuit 560 can convert received audio data into an electrical signal and send it to the speaker 561, which then converts it into a sound signal and outputs it. Meanwhile, the microphone 562 converts the collected sound signal into an electrical signal, which the audio circuit 560 receives and converts into audio data and outputs. After processing the audio data, the processor 580 transmits the audio data to another mobile phone or the like via the RF circuit 510, or outputs the audio data to the memory 520 for further processing.

[0144] WiFi is a short-range wireless transmission technology. A WiFi module 570 enables a mobile phone to provide users with wireless broadband Internet access, helping them send and receive email, browse the web, access streaming media, and the like. While FIG. 5 shows WiFi module 570, it should be understood that it is not a necessary component of a mobile phone and may be omitted entirely, if desired, without changing the essence of the invention.

[0145] The processor 580 is the control center of the mobile phone and is connected to each part of the mobile phone through various interfaces and lines. It executes software programs and / or modules stored in the memory 520 and accesses data stored in the memory 520 to perform various functions of the mobile phone, process data, and thereby perform overall monitoring of the mobile phone. Optionally, the processor 580 may include one or more processing units. Preferably, the processor 580 may integrate an application processor and a modem processor. Here, the application processor mainly processes the operating system, user interface, and application programs, and the modem processor mainly processes wireless communication. It is understandable that the modem processor may not be integrated into the processor 580.

[0146] The mobile phone further includes a power supply 590 (e.g., a battery) that supplies power to each component, and preferably the power supply can be logically connected to the processor 580 by a power management system, thereby realizing functions such as charging, discharging, and power consumption management by the power management system. Although not shown, the mobile phone can further include a camera, a Bluetooth module, etc., which will not be repeated here.

[0147] In an embodiment of the present disclosure, the processor 580 is configured to determine, when a terminal device is in a radio resource control inactive (RRC_INACTIVE) state, a period at which the terminal device monitors paging based on the first period parameter when the terminal device monitors paging without using a paging time window (PTW) and / or a paging hyperframe (PH) while a first period parameter is set.
