Description

[Technical Field]

[0001] The present disclosure relates to the field of wireless communication technology, but is not limited to the field of wireless communication technology, and in particular to information processing methods and apparatuses, communication devices and storage media. [Background technology]

[0002] User Equipment (UE) may also be referred to as a terminal device or terminal. To extend standby time, it is necessary to consider both low power consumption and low latency of services. Therefore, an extended discontinuous reception (eDRX) mechanism has been proposed, in which the UE wakes up or sleeps according to the eDRX period of the eDRX mechanism.

[0003] In some cases, if the eDRX period is long enough, a Paging Time Window (PTW) is configured within the wake-up duration of the eDRX period. The UE can monitor the paging channel within the PTW to receive downlink data to monitor, and sleep for the rest of the time, thereby further saving the UE power consumption. Summary of the Invention [Problem to be solved by the invention]

[0004] Embodiments of the present disclosure provide an information processing method and apparatus, a communication device, and a storage medium. [Means for solving the problem]

[0005] A first aspect of an embodiment of the present disclosure provides an information processing method executed by a UE or a network device, comprising a step of determining a target time domain start position of a first PTW based on a time domain overlap situation between a candidate time domain position of a first PTW of the UE and a time domain position of a second PTW, wherein the first PTW is a PTW assigned to the UE by an access network (RAN), and the second PTW is a PTW assigned to the UE by a core network (CN).

[0006] A second aspect of an embodiment of the present disclosure provides a first determination module configured to determine a target time domain start position of a first paging time window PTW of a user equipment (UE) based on a time domain overlap situation between a candidate time domain position of the first PTW and a time domain position of a second PTW, wherein the first PTW is a PTW assigned to the UE by an access network (RAN), and the second PTW is a PTW assigned to the UE by a core network (CN).

[0007] A third aspect of an embodiment of the present disclosure provides a communications device including a processor, a transceiver, a memory, and an executable program stored in the memory and executable by the processor, wherein the processor, when executing the executable program, performs an information processing method provided by any of the technical solutions of the first aspect described above.

[0008] A fourth aspect of an embodiment of the present disclosure provides a computer storage medium having an executable program stored thereon, the executable program being capable of realizing an information processing method provided by any of the technical solutions of the first aspect described above when executed by a processor. [Effects of the Invention]

[0009] The technical solution provided by the embodiments of the present disclosure does not simply determine the candidate time domain position of the first PTW as the final time domain start position (i.e., target time domain start position) of the first PTW, but determines the target time domain start position of the first PTW based on the overlap between the candidate time domain position of the first PTW and the time domain position of the second PTW. This allows the candidate time domain position of the first PTW and the time domain position of the second PTW to be referenced simultaneously, and fully takes into account the correlation between the first PTW and the second PTW, making the time domain position of the first PTW more appropriate and further reducing the power consumption of the UE.

[0020] As shown in FIG. 2, an embodiment of the present disclosure provides an information processing method performed by a UE or a network device, and the information processing method includes the following step S1110. At S1110, a target time domain start position of the first PTW is determined based on a time domain overlap situation between a candidate time domain position of the first PTW of the UE and a time domain position of a second PTW, where the first PTW is a PTW assigned to the UE by the RAN and the second PTW is a PTW assigned to the UE by the CN.

[0021] The UE may be the UE 11 shown in Fig. 1. The network device may also be the network device 12 shown in Fig. 1. Illustratively, the network device may be the access device described in the above-mentioned embodiment.

[0022] The information processing method is performed by a UE or a network device. For example, the UE can determine a target time domain start position of the first PTW and then determine from which position in the time domain it needs to start monitoring for a paging message. If the performing device is a network device, after determining the target time domain start position of the first PTW, the network device can determine when to send a paging message to the UE so that the UE can monitor for the paging message.

[0023] For example, the RAN may configure first eDRX parameters for the UE, and the CN may configure second eDRX parameters for the UE.

[0024] The first eDRX parameters configured for the UE by the RAN are eDRX parameters for inactive mode eDRX, or eDRX parameters used for RAN paging (extended DRX for RAN paging), or are called eDRX parameters configured by the RAN. The eDRX parameters can be configured by the RAN.

[0025] The second eDRX parameters configured for the UE by the CN are eDRX parameters for idle mode eDRX, or eDRX parameters used for CN paging, or also referred to as eDRX parameters assigned by a higher layer, and the eDRX parameters can be configured by a higher layer. Exemplarily, the first eDRX parameters may include at least one of a first eDRX period and a time length of a first PTW.

[0026] Illustratively, the time length of the first PTW is much shorter than the first eDRX cycle.

[0027] Note that the time length of the first PTW is a selectable parameter, and if the first eDRX parameters do not include the time length of the first PTW, it can be considered by default that there is no need to set a PTW within the first eDRX cycle. Alternatively, if the time length of the first eDRX cycle is less than a predetermined time length, it can be considered by default that there is no need to set the first PTW within the first eDRX cycle.

[0028] If a first PTW is set within a first eDRX cycle, the candidate time domain start position of the first PTW in each first eDRX cycle can be determined based on a protocol agreement or a prior agreement between the network device and the UE. The first eDRX parameters may be configured for the UE by an access network device, such as a base station.

[0029] Illustratively, the step of determining the candidate time domain location of the first PTW based on the first eDRX parameter may be as follows: Based on the first eDRX period, a hyperframe number of the first PTW indicating the hyperframe (PH) in which the candidate time domain start position of the first PTW is located is determined, and based on the first eDRX period, a radio frame number indicating the radio frame (PTW_start) in which the candidate time domain start position of the first PTW is located is determined.

[0030] Specifically, for example, H-SFN mod T eDRX_RAN =(UE_ID_H mod T eDRX_RAN ), where H-SFN is the hyperframe number, and T eDRX_RAN may be the first eDRX cycle, and UE_ID_H may be the most significant (i.e., the most significant) 13 bits of the hash (identifier, ID) of the UE. Exemplarily, UE_ID_H may be the most significant 13 bits of the hash (ID) of the UE. SFN = 128 * i eDRX_RAN , i eDRX_RAN = floor(UE_ID_H / T eDRX_RAN ) mod 8. SFN is the radio frame number, i eDRX_RAN is the sequence number of the first eDRX cycle.

[0031] In this way, the H-SFN and SFN may be the calculation of the candidate time domain start position of the first PTW described above. eDRX_RANand calculate the time domain end position of the first PTW. eDRX_RAN may be the length of the first PTW.

[0032] Note that the time length of the first PTW is a selectable parameter, and if the first eDRX parameters do not include the time length of the first PTW, it can be considered by default that there is no need to set a PTW within the first eDRX cycle. Alternatively, if the time length of the first eDRX cycle is less than a predetermined time length, it can be considered by default that there is no need to set the first PTW within the first eDRX cycle.

[0033] If a first PTW is set within a first eDRX cycle, the candidate time domain start position of the first PTW in each first eDRX cycle can be determined based on a protocol agreement or a prior agreement between the network device and the UE.

[0034] Illustratively, the second eDRX parameters may include at least one of a second eDRX period and a time length of a second PTW. The second eDRX parameters may be configured for the UE by a core network device of a mobility management entity or an access management function.

[0035] Illustratively, the step of determining the time domain position of the second PTW based on the second eDRX parameters may be as follows: Based on the second eDRX period, a hyperframe number of the second PTW indicating the hyperframe in which the time domain start position of the second PTW is located is determined, and based on the second eDRX period, a radio frame number indicating the radio frame in which the time domain start position of the second PTW is located is determined.

[0036] Specifically, for example, H-SFN mod T eDRX_ CN = (UE_ID_H mod T eDRX_CN ), where H-SFN is the hyperframe number, and TeDRX_CN may be the second eDRX cycle, and UE_ID_H may be the most significant bits of a hash (identifier, ID) of the UE. Exemplarily, UE_ID_H may be a hash ID of the most significant 13 bits of the UE identifier. SFN = 128 * i eDRX_ CN , i eDRX_CN = floor(UE_ID_H / T eDRX_ CN ) mod 8. SFN is the radio frame number, i eDRX_ CN is the sequence number of the second eDRX cycle.

[0037] Thus, the H-SFN and SFN may be the calculation of the time domain starting position of the second PTW as described above. eDRX_CN and calculate the time domain end position of the second PTW. eDRX_ CN may be the length of the second PTW.

[0038] Illustratively, the first eDRX cycle is much shorter than the second eDRX cycle, and / or illustratively, the time length of the second PTW is equal to or greater than the time length of the first PTW.

[0039] In this way, after the UE receives the first eDRX parameter and the second eDRX parameter, the UE can determine, based on the first eDRX parameter and the second eDRX parameter, an eDRX period and / or a PTW, etc. that the UE needs to perform when starting the eDRX mechanism. Furthermore, because both the first eDRX parameter and the second eDRX parameter are from the network device, the network device can determine the eDRX period and / or a PTW, etc., based on the first eDRX parameter and the second eDRX parameter.

[0040] In an embodiment of the present disclosure, when the CN and RAN respectively set a first PTW and a second PTW for the UE, taking into consideration that it is the same UE, the time domain overlap situation between the first PTW and the second PTW is taken into consideration when determining the target time domain start position of the first PTW in order to further reduce the power consumption of the UE.

[0041] Illustratively, the step S1110 may include determining a candidate time domain range for a first PTW and determining a time domain position for a second PTW.

[0042] Since both the first PTW and the second PTW are periodically distributed in the time domain according to the corresponding eDRX cycle, after determining the candidate time domain start position of the first PTW, determine whether it has an overlapping relationship with the time domain position of any one of the second PTWs based on the candidate time domain position of the mth first PTW, where m is any natural number.

[0043] If the candidate time domain range of the mth first PTW has a range that overlaps with the time domain position of the second PTW, it is determined that the candidate time domain position of the mth first PTW overlaps with the second PTW in the time domain.

[0044] If the candidate time-domain position of the mth first PTW does not have an overlapping range with the time-domain position of the second PTW, it is determined that the candidate time-domain position of the mth first PTW does not overlap with the second PTW in the time domain. The candidate time-domain position of the mth first PTW may be the candidate time-domain start position of the mth first PTW and the candidate time-domain end position of the mth first PTW. Illustratively, if the candidate start range and / or the candidate time-domain end position of the mth first PTW are within one second PTW, it is determined that the candidate time-domain position of the mth first PTW overlaps with the second PTW in the time domain; otherwise, it is determined that the candidate time-domain position of the mth first PTW does not overlap with the second PTW in the time domain.

[0045] Alternatively, if the calculated PH of the mth first PTW is the same as the PH of one second PTW, the candidate time domain position of the mth first PTW is considered to overlap in the time domain with the second PTW.

[0046] After determining the overlap situation between the candidate time domain position of the first PTW and the time domain of the second PTW, the target time domain starting position of the first PTW is finally determined.

[0047] Step S1110 may include: re-determining reference parameters of the target time domain start position of the first PTW based on a time domain overlap situation between the candidate time domain position of the first PTW of the UE and the time domain position of the second PTW; and determining the target time domain start position of the first PTW based on the re-determined reference parameters.

[0048] After determining the target time domain start position of the first PTW, a target end position of the first PTW is determined based on the time length of the first PTW defined by the first eDRX parameters.

[0049] In this way, in an embodiment of the present disclosure, while taking into account the correlation of the eDRX mechanisms of the same UE, specifically, based on the overlap situation between the candidate time domain position of the first PTW and the time domain position of the second PTW, the time domain start position of the first PTW is determined again, i.e., the target time domain start position of the first PTW is obtained, thereby making the time domain overlap range between the first PTW and the second PTW as large as possible while executing the eDRX mechanism according to the first eDRX, and saving the UE's power consumption as much as possible.

[0050] When the first eDRX cycle is shorter than the second eDRX cycle, the frequency of occurrence of the first eDRX cycle in the time domain is higher than the frequency of the second eDRX cycle. For example, when the first eDRX cycle is equal to 1 / 3 of the second eDRX cycle, three first eDRX cycles will occur in one second eDRX cycle in the time domain. Generally, given that the lengths of the wake-up period and the sleep period within an eDRX cycle are equal and the PTW is set to the wake-up period, the first PTW within at least one first eDRX cycle does not overlap with the second PTW of the second eDRX.

[0051] Thus, based on the candidate time-domain positions of the first PTWs and the time-domain positions of the second PTWs, the candidate first PTWs can be divided into two types: a first type of first PTW whose candidate time-domain positions at least partially overlap with the time-domain positions of the second PTWs, and a second type of first PTW whose candidate time-domain positions do not overlap with the time-domain positions of the second PTWs. The final time-domain positions of the two types of first PTWs can be determined by different reference parameters.

[0052] In some embodiments, step S1110 may include dividing the first PTW into a first type first PTW and a second type first PTW based on a time domain overlap situation between the candidate time domain position of the first PTW of the UE and the time domain position of the second PTW, and re-determining reference parameters, wherein the re-determined reference parameters are used to determine a target time domain start position of at least the second type first PTW and to determine that the time domain start positions of the first type first PTW and the corresponding second PTW overlap.

[0053] For example, as shown in FIG. 7, PTW1 is a second PTW and PTW2 is a first PTW. The location of PTW2 in FIG. 7 is a candidate time-domain location for the first PTW. From this, it can be seen that the second PTWs are periodically distributed in the time domain. According to the candidate time-domain locations, the first PTWs are also periodically distributed in the time domain. The second and fourth PTW2 in FIG. 7 do not overlap with any one PTW1 in the time domain, while the first, third, and fifth PTW2 in FIG. 7 overlap with PTW1 in the time domain. The first, third, and fifth PTW2 in FIG. 7 are first PTWs of the first type described above, and the remaining PTW2s are first PTWs of the second type. Of course, this is merely an example, and specific implementations are not limited to this example.

[0054] As shown in FIG. 3, an embodiment of the present disclosure provides an information processing method performed by a user equipment (UE) or a network device, and the information processing method includes the following step S1210. In S1210, if the candidate time domain position of the nth first PTW determined based on the first eDRX parameter has an overlap in the time domain with the mth second PTW, it is determined that the time domain start position of the nth first PTW and the time domain start position of the mth second PTW overlap.

[0055] In some embodiments, the n and the m may be any natural number, ie, the natural number is 0 or a positive integer.

[0056] If the candidate time-domain position of the nth first PTW has overlap in the time domain with the mth second PTW, the time-domain start position of the nth first PTW is aligned with the time-domain start position of the mth second PTW, thereby maximizing the overlap in the time-domain positions between the nth first PTW and the mth second PTW.

[0057] In this embodiment, this corresponds to determining the time domain position of the first PTW based on the time domain position of the second PTW, so in this case the reference parameter for determining the time domain position of the nth first PTW is the time domain position of the mth second PTW.

[0058] As shown in FIG. 4, an embodiment of the present disclosure provides an information processing method performed by a user equipment (UE) or a network device, and the information processing method includes the following step S1310. In S1310, if the candidate time domain position of the nth first PTW determined based on the first eDRX parameters does not overlap with the mth second PTW in the time domain, the time domain start position of the nth first PTW is determined based on at least the first eDRX parameters.

[0059] In some embodiments, the n and the m may be any natural number, ie, the natural number is 0 or a positive integer.

[0060] If the candidate time domain position of the nth first PTW has no overlap in the time domain with the mth second PTW, the reference parameters for determining the time domain start position of the nth first PTW include at least the first eDRX parameter.

[0061] In addition, in the embodiment of the present disclosure, in addition to using the first eDRX parameter, it is also possible to determine the time domain start position of the first PTW by referring to other parameters.

[0062] Illustratively, the first eDRX parameters include at least a first eDRX cycle, and the second eDRX parameters include at least a second eDRX cycle.

[0063] The step of determining the time domain start position of the nth first PTW based on at least the first eDRX parameter includes the step of determining, based on the first eDRX period, a hyperframe number indicating the hyperframe in which the time domain start position of the nth PTW is located, and the step of determining, based on the first eDRX period or the second eDRX period, a radio frame number indicating the radio frame in which the time domain start position of the nth PTW is located.

[0064] Illustratively, H-SFN mod T eDRX_RAN = (UE_ID_H mod T eDRX_RAN ), where H-SFN is the hyperframe number, and T eDRX_RAN may be the first eDRX period, and UE_ID_H may be the most significant bits in the hash (identifier, ID) of the UE. For example, UE_ID_H may be the most significant 13-bit hash ID of the UE identifier. SFN = 128 * i eDRX_RAN , i eDRX_RAN = floor(UE_ID_H / T eDRX_RAN ) mod 8, or SFN = 128 * i eDRX_ CN , i eDRX_CN = floor(UE_ID_H / T eDRX_ CN ) mod 8. SFN is the radio frame number, i eDRX_RAN is the sequence number of the first eDRX cycle. eDRX_ CN is the sequence number of the second eDRX cycle.

[0065] In this way, the H-SFN and SFN may be the calculation of the candidate time domain start position of the first PTW described above. eDRX_RAN is used to calculate the time domain end position of the first PTW.

[0066] Of course, the above merely provides a method for independently calculating the target time domain start position of the first PTW when the candidate time domain range of the first PTW and the time domain range of the second PTW do not overlap.

[0067] As shown in FIG. 5, an embodiment of the present disclosure provides an information processing method performed by a user equipment (UE) or a network device, and the information processing method includes step S2110 and step S2120. At S2110, a target time domain start position of the first PTW is determined based on a time domain overlap situation between a candidate time domain position of the first PTW of the UE and a time domain position of a second PTW, where the first PTW is a PTW assigned to the UE by an access network (RAN) and the second PTW is a PTW assigned to the UE by a core network (CN). At S2120, paging monitoring is performed using a paging index of the UE in an idle state within the first PTW that overlaps with the second PTW in the time domain.

[0068] In some embodiments, the inactive mode paging index or the paging index used for RAN paging may be the first paging index, and the paging index used for CN paging or the idle state paging index may be the second paging index. The first paging index and the second paging index both refer to a paging occasion (PO), and a base station sends a paging message on the PO to page a UE.

[0069] In an embodiment of the present disclosure, a UE monitors paging messages based on a second paging index within a first PTW that overlaps with a second PTW in the time domain. Then, at the overlapping time domain positions of the first PTW and the second PTW, the UE monitors CN paging messages and RAN paging messages at the same or multiple paging occasions (POs). This reduces the UE power consumption that would be incurred if the UE monitors CN paging messages and RAN paging messages at different POs based on the first paging index and the second paging index, respectively, thereby reducing the UE power consumption.

[0070] As shown in FIG. 6, an embodiment of the present disclosure provides an information processing method performed by a user equipment (UE) or a network device, and the information processing method includes the following steps S2210 and S2220. At S2210, it is determined whether a first PTW exists based on the first eDRX parameter. At S2220, if it is determined based on the first eDRX parameters that the first PTW does not exist and based on the second eDRX parameters that the second PTW exists, paging monitoring is performed within the second PTW using the paging index of the UE in idle state.

[0071] For example, if the first eDRX parameter does not have a first PTW set, and / or the first eDRX period set by the first eDRX parameter is equal to or less than a predetermined value, it is determined that the first PTW is not set in the first eDRX parameter, i.e., the first PTW does not exist. The predetermined value may be 10.24 seconds.

[0072] If the first PTW does not exist, in order to reduce the UE simultaneously monitoring RAN paging messages and CN paging messages in different POs within the second PTW, the paging occasion to be monitored is determined similarly within the second PTW based on the paging index of the second eDRX parameter, thereby further reducing the power consumption caused by the UE monitoring RAN paging messages and / or CN paging messages.

[0073] However, at the same time, because a second PTW is set in the second eDRX parameters, a portion of the period during which the UE monitors for RAN paging messages is within the second PTW and another portion is outside the second PTW. When the UE is within the second PTW, the UE monitors for CN paging messages and RAN messages using the PO indicated by the second paging index, rather than monitoring for RAN paging messages using the PO indicated by the first paging index. When the UE is outside the second PTW, the UE continues to monitor for RAN paging messages using the PO indicated by the second paging index. That is, the method further includes determining a paging time for monitoring for RAN paging messages based on the paging index of the first eDRX parameters, at a time domain position outside the second PTW and for monitoring for RAN paging messages.

[0074] An embodiment of the present disclosure provides an information processing method, and the information processing method may be as follows. The operation method in which a terminal in an RRC inactive mode uses eDRX is protected, i.e., the terminal determines paging parameters to be used by the terminal in the RRC inactive mode based on eDRX parameters determined by the core network (i.e., the second eDRX parameters described above) and / or eDRX parameters determined by the base station (i.e., the first eDRX described above). The paging parameters include an eDRX cycle, and the paging parameters include a PTW, which is determined by the following parameters. Hyperframe in which paging is located: Paging Hyperframe (PH), PTW_start: defines the first radio frame of the PH as part of the PTW, that is, PTW_start is the time domain start position of the PTW mentioned above. PTW_end: defines the last radio frame of the PTW, i.e., PTW_end is the time domain end position of the PTW. The UE monitors the period T of the paging message within or outside the PTW. The period may be the DRX period.

[0075] The core network assigns second eDRX parameters to the terminal, which may be idle mode edrx parameters or extended DRX for CN paging parameters or eDRX parameters configured by upper layer.

[0076] The base station has assigned the eDRX parameters to the terminal, i.e., the second eDRX parameters described above, i.e., the inactive mode eDRX parameters, or the extended discontinuous reception parameters used for RAN paging (extended DRX for RAN paging), or the extended discontinuous reception parameters configured by RAN (eDRX configured by RAN).

[0077] Because the first eDRX parameter and the second eDRX parameter are present, a first PTW and a second PTW may also be present. For example, if the first eDRX period and the second eDRX period indicated by the first eDRX parameter and the second eDRX parameter are both greater than 10.24 seconds, the first eDRX period indicated by the first eDRX parameter has a first PTW, and the second eDRX period indicated by the second eDRX parameter has a second PTW.

[0078] Based on whether the first PTW and the second PTW have an overlapping relationship in the time domain, the first PTW may be divided into a first type first PTW and a second type first PTW, where the first PTW may be referred to as a PTW used for the RAN (PTW for RAN) or a PTW in an inactive mode or a PTW in an inactive mode, and the second PTW may be referred to as a PTW used for the CN (PTW for CN) or an idle PTW or an idle PTW.

[0079] To determine the time domain start position of a PTW, whether it is the first or second PTW, first determine the H-SFN, i.e., hyperframe (PH, Paging Hyperframe), that appears in that time domain, and then determine eight candidate start positions (PTW_start) within the hyperframe HSFN. If the first and second PTWs are determined to have an overlap in the time domain based on their time domain start positions and window lengths, the first and second PTWs are considered to have an overlap in the time domain.

[0080] As an example, if the paging hyperframes (PH) in which the first and second PTWs appear in the time domain are equal, then the two types of PTWs are considered to have overlap in the time domain. That is, H-SFN is H-SFN mod T eDRX_CN = (UE_ID_H mod T eDRX_CN), and H-SFN mod T eDRX_RAN = (UE_ID_H mod T eDRX_RAN ) are simultaneously satisfied, the two types of PTW are considered to have overlap in the time domain.

[0081] As one example, if the occurrence period or frequency of the first PTW and the second PTW in the time domain has an integer multiple relationship, for example, two times, the second PTW will have an overlap in the time domain with one first PTW every other PTW.

[0082] As an example, the occurrence period or frequency of the first PTW and the second PTW in the time domain has an integer multiple relationship, for example, T eDRX_CN= 256 hyperframe is T eDRX_RAN= The period is twice the number of 128 hyperframes. When UE_ID_H=0, the occurrence periods of the first PTW and the second PTW in the time domain are 0 hyperframe, 256 HSFN, 512 HSFN, ... and 0 hyperframe, 128 HSFN, 256 HSFN, respectively. In this case, the second PTW overlaps with one first PTW in the time domain every other PTW, i.e., 0, 256 HSFN, 512 HSFN, ... overlap with the first PTW in the time domain, and other PHs do not overlap in the time domain.

[0083] As an example, if the occurrence period or frequency of a first PTW and a second PTW in the time domain do not have an integer multiple relationship, for example, if the occurrence period of the first PTW is M and the occurrence period of the second PTW is N, it will take M * N for one overlap of the PTW in the time domain to occur.

[0084] Operation method 1: The time domain start position (PTW_start) of the first type PTW, i.e., the candidate time domain start position in the hyperframe HFN, can be determined based on the eDRX parameters determined by the core network. At the same time, for determining other parameters, the period (PH) at which the first PTW appears can be set by the base station, and the window length of the first PTW can be set by the base station.

[0085] The time domain start position of the PTW is the first radio frame of the PH that is part of the PTW.

[0086] As an example, the time domain start position (PTW_start) of the first PTW (i.e., the radio frame in the hyperframe in which the PTW occurs) may be determined by the eDRX period within the eDRX parameters determined by the core network.

[0087] For example, for a PTW2 (first PTW) provided by the base station and a PTW1 (second PTW) provided by the core network, regardless of whether the PTWs of the CN and the RAN have overlapping portions in the time domain, the time domain start position (PTW_start) of the first PTW is determined based on the eDRX period in the eDRX parameters determined by the core network, i.e., coincides with the start point of the PTW of the CN. Regarding the determination of other parameters, the period (PH) at which the first PTW appears is set by the base station, and the window length of the first PTW may be set by the base station or by the core network.

[0088] As an example, the time domain start position (PTW_start) of the first PTW can be determined based on the time domain start position (PTW_start) of the second PTW. Regarding the determination of other parameters, the period (PH) at which the first PTW appears can be set by the base station, and the window length of the first PTW can be set by the base station. The advantage of doing so is that the time domain start position (PTW_start) of the second PTW can be directly used for determination without calculation.

[0089] As an example, The hyperframe used for RAN paging is H-SFN mod T eDRX_RAN = (UE_ID_H mod T eDRX_RAN ), the following formula must be satisfied.

[0090] Illustratively, H-SFN is the hyperframe number, and T eDRX_RAN may be an eDRX cycle assigned to the terminal by the base station or the RRC, and may be expressed in terms of hyperframes, for example, T eDRX_RAN may be equal to or greater than 2 hyperframes and equal to or less than 1024 hyperframes.

[0091] The time domain start position (PTW_start) of the PTW used for RAN paging is SFN = 128 * i eDRX_CN , the following equation must be satisfied. i eDRX_CN = floor(UE_ID_H / T eDRX_CN ) mod 8. The time domain end position of the PTW is It can be calculated by the formula: SFN = (PTW_start + L*100 - 1) mod 1024, where L is the PTW window length used for RAN paging. The PTW window length can be set by the RRC layer or the core network.

[0092] For example, as shown in FIG. 7, PTW1 is a second PTW and PTW2 is a first PTW. The position where PTW2 is located in FIG. 7 is a candidate time-domain position for the first PTW. From this, it can be seen that the second PTWs are periodically distributed in the time domain. According to the candidate time-domain positions, the first PTWs are also periodically distributed in the time domain, and the second and fourth PTW2 in FIG. 7 do not overlap with any one PTW1 in the time domain, while the first, third, and fifth PTW2 in FIG. 7 overlap with PTW1 in the time domain. The first, third, and fifth PTW2 in FIG. 7 are first PTWs of the first type described above, and the remaining PTW2s are first PTWs of the second type. The time domain start positions (PTW_start) of the first type PTWs (the first, third and fifth PTW2 in Figure 7) can all be determined based on the time domain start position (PTW_start) of the second PTW, and the time domain start positions (PTW_start) of the second type PTWs (the second and fourth PTW2 in Figure 7) can all be determined based on the time domain start position (PTW_start) of the second PTW.

[0093] Operation method 2: That is, the decision is made according to the determination result as to whether the first PTW and the second PTW overlap in the time domain.

[0094] For a portion of a PTW where the first PTW and the second PTW overlap in the time domain, the time domain start position (PTW_start) of the first PTW can be determined based on eDRX parameters determined by the core network, where the eDRX parameters determined by the core network may be an eDRX cycle setting corresponding to the second eDRX parameters. For a portion of a PTW where the first PTW and the second PTW do not overlap in the time domain, the time domain start position (PTW_start) of the first type PTW can be determined based on the eDRX cycle in the eDRX parameters determined by the base station. At the same time, for determining other parameters, the period (PH) at which the first PTW appears can be set by the base station, and the window length of the first PTW can be set by the base station or the core network.

[0095] As an example, i.e., if H-SFN (this part describes a scenario in which PTWs have time domain overlap), H-SFN mod T eDRX_CN = (UE_ID_H mod T eDRX_CN ), and H-SFN mod T eDRX_RAN = (UE_ID_H mod T eDRX_RAN ) are satisfied simultaneously, the time domain start position (PTW_start) of the PTW used for RAN paging is SFN = 128 * i eDRX_CN , where i eDRX_CN = floor(UE_ID_H / T eDRX_CN ) mod 8. The time domain end position of the PTW can be calculated by the formula: SFN = (PTW_start + L*100 - 1) mod 1024, where L is the PTW window length used for RAN paging, which may be configured by the RRC layer or the core network.

[0096] Otherwise (this section describes a scenario where the PTWs do not have time domain overlap) H-SFN mod T eDRX_RAN = (UE_ID_H mod T eDRX_RAN ), the time domain start position (PTW_start) of the PTW used for RAN paging is SFN = 128 * i eDRX_RAN , where i eDRX_RAN = floor(UE_ID_H / T eDRX_RAN ) mod 8. The time domain end position of the PTW can be calculated by the formula: SFN = (PTW_start + L*100 - 1) mod 1024, where L is the window length of the PTW used for RAN paging, which may be configured by the RRC layer.

[0097] For example, as shown in FIG. 7, PTW1 is a second PTW and PTW2 is a first PTW. The position where PTW2 is located in FIG. 7 is a candidate time-domain position for the first PTW. From this, it can be seen that the second PTWs are periodically distributed in the time domain. According to the candidate time-domain positions, the first PTWs are also periodically distributed in the time domain, and the second and fourth PTW2 in FIG. 7 do not overlap with any one PTW1 in the time domain, while the first, third, and fifth PTW2 in FIG. 7 overlap with PTW1 in the time domain. The first, third, and fifth PTW2 in FIG. 7 are first PTWs of the first type described above, and the remaining PTW2s are first PTWs of the second type. The time domain start positions (PTW_start) of the first type PTWs (the first, third and fifth PTW2 in Figure 7) can all be determined based on the time domain start position (PTW_start) of the second type PTWs (the second and fourth PTW2 in Figure 7) can all be determined based on PTW_start'.

[0098] The time domain start position (PTW_start) of the second PTW is SFN = 128 * i eDRX_CN , where i eDRX_CN = floor(UE_ID_H / T eDRX_CN ) mod 8, and PTW_start' is SFN = 128 * i eDRX_RAN , the equation must be satisfied, and i eDRX_RAN = floor(UE_ID_H / T eDRX_RAN ) mod 8.

[0099] In the above description, when the first and second PTWs of a UE have an overlapping portion in the time domain, the method for determining the time domain start position of the first PTW of the UE can be any of the above methods. This time domain start position is also referred to simply as the start point. After the start point of the first PTW is determined, the duration of the overlapping portion needs to be determined. The duration of the overlapping portion is determined by protocol agreement, instruction from the network device, or negotiation between the UE and the network device.

[0100] Illustratively, the duration of the overlapping portion may be the window length L1 of the first PTW set by the first eDRX parameters, or the window length L2 of the second PTW set by the second eDRX parameters.

[0101] In the case of a UE, in the overlapping portion in the time domain between the first PTW and the second PTW, as shown in the cross-hatched area in Figure 7, CN paging messages and RAN paging messages are monitored at the minimum period among the specific UE DRX period set by the core network, the RAN paging cycle, and the default DRX period set by the base station.

[0102] In addition to the PTW portions that overlap in the time domain, there are also PTWs for monitoring CN paging, which are indicated by a right-hand diagonal line pattern in Fig. 7, and PTWs for monitoring RAN paging, which are indicated by a left-hand diagonal line pattern in Fig. 7. For the PTWs for monitoring CN paging, the UE monitors CN paging at the minimum cycle between the specific UE DRX cycle set by the core network and the default DRX cycle set by the base station. On the other hand, for the PTWs for monitoring RAN paging, the UE monitors RAN paging at the RAN paging cycle set by the base station.

[0103] In another embodiment, for PTW portions that overlap in the time domain, the terminal can use any of the above methods to determine the starting points of the overlapping PTW portions. After the starting points of the overlapping PTW portions are determined, the durations of the overlapping PTW portions also need to be determined. The durations of the overlapping PTW portions are determined by the length of time preset in the protocol (the PTW length of time L1 set in the first eDRX parameters or the PTW length of time L2 set in the second eDRX parameters).

[0104] In this case, in the case of a terminal, in the PTW portion that overlaps in the time domain (the cross-hatched portion in Figure 7), CN paging and RAN paging are monitored at the shortest cycle among the specific UE DRX cycle set by the core network, the RAN paging cycle, and the default DRX cycle set by the base station.

[0105] In addition to the PTW portions that overlap in the time domain, there are also PTWs for monitoring CN paging (i.e., the right-hand diagonal line pattern portion in Figure 7) and PTWs for monitoring RAN paging (i.e., the left-hand diagonal line pattern portion in Figure 7).Therefore, in the PTWs for monitoring CN paging, the terminal monitors CN paging at the minimum cycle among the specific UE DRX cycle set by the core network and the default DRX cycle set by the base station, and in the PTWs for monitoring RAN paging, the terminal monitors RAN paging at the RAN paging cycle set by the base station.

[0106] In some embodiments, the first eDRX parameter and the second eDRX parameter are combined to obtain one third or common PTW for simultaneous monitoring of CN paging and RAN paging, which necessarily means there is an overlap in the PTW time domain.

[0107] The PH of the third PTW is obtained based on the third eDRX parameter, for example, by obtaining the minimum period among the periods of the first eDRX and second eDRX parameters to obtain one third eDRX period.

[0108] In one embodiment, H-SFN (which is the scenario described in this section where PTWs have time domain overlap) is used. eDRX = (UE_ID_H mod T eDRX ), where T eDRX= min{ T eDRX_CN , T eDRX_RAN} or T eDRX_RAN If both of these conditions are satisfied at the same time, the time domain start position (PTW_start) of the third PTW is SFN = 128 * i eDRX , where i eDRX = floor(UE_ID_H / T eDRx ) mod 8. The time domain end position of the PTW can be calculated by the formula SFN = (PTW_start + L*100 - 1) mod 1024, where L is the window length of the PTW, which may be set by the RRC layer or the core network.

[0109] In this embodiment, the monitoring operation of the UE is as follows. Within the common PTW, T may be the minimum of the UE's specific DRX period, the RAN paging period, and the default DRX period.

[0110] If the RAN paging cycle is configured by a higher layer, T needs to refer to the RAN paging cycle; otherwise, it does not need to refer to the RAN paging cycle. The default DRX cycle may be a DRX cycle broadcast via a system message. If the system message includes a default DRX cycle, T needs to refer to the default DRX cycle; otherwise, it does not need to refer to the default DRX cycle. T may be a period for monitoring CN paging messages and / or RAN paging messages within the PTW.

[0111] Regarding the determination of the paging index, for the period during which the UE needs to simultaneously monitor the CN paging message (paging) and the RAN paging message (paging), the paging index (Index (i_s), indicating the index of the PO) is the same as the paging index in the idle state.

[0112] in particular, If there is no PTW of the first type (i.e., RAN PTW), within the second PTW (CN PTW), for one RRC inactive mode terminal, the paging index (Index (i_s), indicating the index of the PO) of its paging message is the same as the paging index of the terminal in RRC idle state.

[0113] The purpose of doing this is to eliminate the case where, within the second PTW (CN PTW), during an overlapping period in which CN paging messages (CN paging) and RAN paging messages (RAN paging) need to be monitored simultaneously, the paging index (Index (i_s), indicating the index of the PO) is the same as the paging index of a terminal in RRC idle state, and therefore CN paging and RAN paging cannot be monitored simultaneously.

[0114] When a first type PTW (i.e., RAN PTW) and a second type PTW (CN PTW) exist, for a UE in RRC inactive mode, in the PTWs that overlap in the time domain, its paging index (Index (i_s), indicating the index of the PO) is the same as the paging index of the UE in RRC idle state. That is, the paging index is calculated using the paging parameters of the UE in idle state.

[0115] The purpose of doing this is to eliminate cases where CN paging and RAN paging cannot be monitored simultaneously by ensuring that the paging index (Index (i_s), indicating the index of the PO) is the same as the paging index of a terminal in RRC idle state during an overlapping period in which CN paging messages (CN paging) and RAN paging messages (RAN paging) need to be monitored simultaneously for PTWs that overlap in the time domain (whose starting point is the starting point of the first or second PTW and whose length is the window length of the first PTW or the window length of the second PTW).

[0116] For the UE inactive mode (i.e., RRC inactive mode), if the eDRX period configured by upper layers (eDRX value configured by upper layers) exceeds 1024 radio frames and the eDRX period configured by the RRC layer (eDRX value configured by RRC) does not exceed 1024 radio frames or the eDRX period is not configured by the RRC layer, the UE uses the RRC idle paging index within the CN PTW (i.e., the second PTW). That is, the UE determines to monitor RAN paging messages and CN paging messages using the idle paging index within the CN PTW. That is, the UE does not monitor RAN paging messages using the inactive mode paging index within the CN PTW.

[0117] For a UE inactive mode (i.e., RRC inactive mode), if the eDRX period configured by upper layers (eDRX value configured by upper layers) exceeds 1024 radio frames and the eDRX period configured by the RRC layer (eDRX value configured by RRC) exceeds 1024 radio frames, the UE determines to monitor paging messages using the RRC idle paging index within the PTWs that overlap in the time domain, i.e., the UE determines to monitor RAN paging messages and CN paging messages using the idle paging index within the PTWs that overlap in the time domain, and does not monitor RAN paging messages using the inactive mode paging index within the PTWs that overlap in the time domain.

[0118] In one embodiment, for a portion where the first PTW and the second PTW of a UE overlap in the time domain, the starting point of the first PTW is determined based on the eDRX period in the first eDRX parameters or the eDRX period in the second eDRX parameters. After the starting point of the first PTW is determined, if the duration of the overlapping portion also needs to be determined, the duration of the overlapping portion is determined by a time length preset in the protocol. Exemplarily, the duration of the overlapping portion may be the window length L1 of the first PTW set in the first eDRX parameters or the window length L2 of the second PTW set in the second eDRX parameters.

[0119] In the case of a UE, in the overlapping portion in the time domain between the first PTW and the second PTW, the UE monitors the CN paging message and the RAN paging message at the minimum cycle among the specific UE DRX cycle set by the core network, the RAN paging cycle, and the default DRX cycle set by the base station, as shown in the cross-hatched area in Figure 7. In this case, when determining the paging index, the idle state paging index is used to determine the monitoring of the RAN paging message and the CN paging message.

[0120] Specifically, in one embodiment, according to the above-described method for determining an overlapping PTW by a terminal, for a portion where a first PTW and a second PTW of a UE overlap in the time domain, the starting point of the overlapping PTW portion is determined based on the eDRX cycle in the first eDRX parameters or the eDRX cycle in the second eDRX parameters. After the starting point of the overlapping PTW portion is determined, if the duration of the overlapping PTW portion also needs to be determined, the duration of the overlapping PTW portion is determined by a time length preset in the protocol (which may be the PTW time length L1 set in the first eDRX parameters or the PTW time length L2 set in the second eDRX parameters).

[0121] In this case, in the case of the terminal, in the PTW portion overlapping in the time domain (the cross-hatched portion in FIG. 7), the terminal monitors CN paging and RAN paging at the shortest cycle among the specific UE DRX cycle set by the core network, the RAN paging cycle, and the default DRX cycle set by the base station. In this case, when determining the paging index, the terminal uses the paging index in the idle state to determine whether to monitor the RAN paging message and the CN paging message.

[0122] As shown in Figure 7, when the first PTW and the second PTW overlap in the time domain and have the same time domain starting position, the window length of the first PTW is shorter than that of the second PTW. When the first PTW and the second PTW have the same time domain starting position and have a shorter window length of the first PTW than that of the second PTW, the first PTW ends before the second PTW. In this case, the UE determines to monitor RAN paging messages and CN paging messages using an idle paging index within the PTW that overlaps in the time domain (within the first PTW).

[0123] As an example, H-SFN (this section describes a scenario where PTWs have time domain overlap) is eDRX_CN = (UE_ID_H mod T eDRX_CN ) and H-SFN mod T eDRX_RAN = (UE_ID_H mod T eDRX_RAN ) are simultaneously satisfied, the time domain start position (PTW_start) of the first PTW is SFN = 128 * i eDRX_CN , where i eDRX_CN = floor(UE_ID_H / T eDRX_CN ) mod 8. The time domain end position of the PTW can be calculated by the formula: SFN = (PTW_start + L*100 - 1) mod 1024, where L is the PTW window length used for RAN paging, which may be configured by the RRC layer or the core network.

[0124] In this case, since the first PTW window length is less than or equal to the second PTW window length, the UE determines to monitor paging messages using the RRC idle paging index within the first PTW window (within the PTWs that overlap in the time domain). That is, the UE determines to monitor RAN paging messages and CN paging messages using the idle paging index within the PTWs that overlap in the time domain.

[0125] In Figure 7, the first, third, and fifth PTW2s overlap with PTW1 in the time domain, and within the overlapping PTWs in the time domain (the first, third, and fifth PTW2s), it is necessary to simultaneously monitor CN paging and RAN paging, so the monitoring of RAN paging messages and CN paging messages is determined using the paging index in the idle state.In the portion excluding the portion where the first, third, and fifth PTW2s overlap with the CN PTW in the time domain, for example, the portion excluding the portion where the first, second, and third PTW1s overlap with the RAN PTW in the time domain (which is the length of the CN PTW minus the RAN PTW window length), it is necessary to monitor only CN paging, so the paging index calculated using the idle state paging parameters is used to determine the monitoring of CN paging messages.

[0126] Since the second and fourth PTW2 in FIG. 7 do not overlap with any one PTW1 in the time domain, the paging index calculated by the inactive mode paging parameters is used to determine monitoring of the RAN paging message.

[0127] The first and second eDRX parameters are combined to obtain a third PTW for simultaneously monitoring CN paging and RAN paging, where the paging index (Index (i_s), indicating the index of the PO) within the third PTW is the same as the paging index in the idle state.

[0128] As shown in FIG. 8 , an embodiment of the present disclosure provides an information processing device, which includes a first determination module 110. The first determination module 110 is configured to determine a target time domain start position of a first PTW based on a time domain overlap situation between a candidate time domain position of the first PTW of a UE and a time domain position of a second PTW, where the first PTW is a PTW assigned to the UE by an access network RAN, and the second PTW is a PTW assigned to the UE by a core network CN.

[0134] In some embodiments, the first eDRX parameters include at least a first eDRX period, and the first determination module 110 is configured to determine, based on the first eDRX period, a hyperframe number indicating a hyperframe in which a time domain starting position of the nth first PTW is located, and to determine, based on the first eDRX period or a second eDRX period, a radio frame number indicating a radio frame in which a time domain starting position of the nth first PTW is located, and the second eDRX period is an eDRX period assigned to the UE by the CN.

The third determination module is configured to, when determining based on the first eDRX parameters that the first PTW does not exist and determining based on the second eDRX parameters that the second PTW exists, monitor paging within the second PTW using a paging index of the UE in idle state.
