Description

Technical Field

[0001] This application relates to the field of wireless communication technology, but is not limited to the field of wireless communication technology, and particularly relates to a paging parameter determination method, apparatus, communication device, and storage medium.

Background Art

[0002] The 5th Generation (5G) cellular mobile communication network uses an extended Discontinuous Reception (eDRX) mechanism to further reduce the power consumption of the terminal. In each eDRX cycle, the terminal can only receive downlink data within the set Paging Time Window (PTW), and the terminal is in a dormant state during the remaining time and does not receive downlink data. The eDRX mechanism can achieve a trade-off between downlink service delay and power consumption. For example, the eDRX mechanism can be used for remote gas opening and closing control.

For example, it may be an electronic control unit with a wireless communication function, or a wireless user equipment device for externally attaching an electronic control unit. Or, the terminal 11 may be a roadside device, for example, a street lamp, a traffic signal, or other roadside devices with a wireless communication function.

[0092] The base station 12 may be a network-side device in a wireless communication system. The wireless communication system may be a 4th generation mobile communication (4G) system, also known as the Long Term Evolution (LTE) system. Or, the wireless communication system may be a 5G system, also known as the new radio (NR) system or 5G NR system. Or, the wireless communication system may be a next-generation system of the 5G system. The radio access network of the 5G system may be called the NG-RAN (New Generation-Radio Access Network). Or, it may be an MTC system.

[0093] Here, the base station 120 may be an evolved Node B (eNB) used in a 4G system. Or, the base station 120 may be a gNB using a centralized and distributed architecture in a 5G system. When the base station 120 uses a centralized and distributed architecture, it usually includes a central unit (CU) and at least two distributed units (DUs). The central unit is provided with a protocol stack of the Packet Data Convergence Protocol (PDCP) layer, the Radio Link Control (RLC) layer, and the Medium Access Control (MAC) layer. The distributed unit is provided with a protocol stack of the Physical (PHY) layer. The embodiments of the present disclosure are not limited to specific implementation forms of the base station 12.

[0094] A wireless connection can be established between the base station 12 and the terminal 11 via a wireless air interface. In different embodiments, the wireless air interface is a wireless air interface based on the fourth-generation mobile communication network technology (4G) standard. Alternatively, the wireless air interface is a wireless air interface based on the fifth-generation mobile communication network technology (5G) standard. For example, the wireless air interface is a new radio. Alternatively, the wireless air interface may be a wireless air interface based on the next-generation mobile communication network technology standard of 5G.

[0095] In some embodiments, an E2E (End to End) connection can be established between terminals 11. For example, it is a scenario such as vehicle-to-vehicle (V2V) communication, vehicle-to-Infrastructure (V2I) communication, and vehicle-to-pedestrian (V2P) communication in vehicle Internet communication (vehicle to everything, V2X).

[0096] In some embodiments, the wireless communication system can further include a network management device 13.

[0097] Some base stations 12 are each connected to a network management device 13. The network management device 13 may be a core network device in a wireless communication system. For example, the network management device 13 may be a Mobility Management Entity (MME) in an Evolved Packet Core (EPC). Alternatively, the network management device may be other core network devices, such as a Serving GateWay (SGW), a Public Data Network GateWay (PGW), a Policy and Charging Rules Function (PCRF), or a Home Subscriber Server (HSS), etc. In the embodiments of the present disclosure, the implementation form of the network management device 13 is not limited.

[0098] The execution entities according to the embodiments of the present disclosure include, but are not limited to, UEs such as mobile phone terminals that support cellular mobile communication, and base stations, etc.

[0099] As an application scenario of the embodiments of the present disclosure, as shown in FIG. 2, there is one PTW in each eDRX cycle. The terminal monitors the paging channel according to the DRX cycle to receive downlink data within the PTW, and the terminal is in a dormant state for the remaining time. The eDRX cycle is from 20.48 seconds (s) to 2.92 hours (h). The value range of the DRX cycle includes {1.28 s, 2.56 s, 5.12 s, or 10.24 s}.

[0100] The eDRX mode means that the terminal device can be reached at any time, but the delay is relatively large. The delay depends on the setting of the eDRX cycle, and a trade-off between low power consumption and delay is possible.

[0101] In the eDRX mechanism, the UE and the core network need to negotiate the eDRX period and the PTW window length. As shown in the procedure of the negotiation process, it includes the following steps 301 to 305. In step 301, the base station instructs the UE to permit the eDRX mechanism, cell-specific DRX, superframe information, etc. via the SIB. In step 302, the UE instructs the core network of the UE-specific DRX period, the expected DRX period, etc. via the attach information or the tracking area update (TAU) information. In step 303, the core network instructs the UE of the eDRX setting, and the eDRX setting includes the eDRX period and the PTW window length. In step 304, the core network transmits a paging message to the base station based on the eDRX setting. In step 305, the base station pages the UE based on the paging message from the core network.

[0102] This negotiation process is negotiated between the UE and the core network via non-access stratum (NAS) messages, and the base station can perform transparent transmission.

[0103] In the non-eDRX mechanism, the UE can monitor the paging message of the radio access network based on at least the radio access network paging cycle.

[0104] In NR, the inactive state of the UE is further introduced. The inactive UE needs to receive paging messages from the core network (CN) and also needs to receive paging messages from the radio access network (RAN).

[0105] A wireless access network can set an inactive state eDRX period for a UE in the inactive state to further reduce the power consumption of the UE in the inactive state.

[0106] When the inactive state eDRX period is not set, a UE in the inactive state generally takes the minimum value from the RAN paging period, the CN paging period, and the default paging period as the monitoring period for paging messages.

[0107] When the inactive state eDRX period is set, the UE in the inactive state monitors paging messages using the monitoring period in the related art, and there is a possibility of missing the monitoring timing. Therefore, it is an urgent problem to solve how the UE in the inactive state monitors paging messages when the inactive state eDRX period is set to reduce the occurrence of paging message loss situations.

[0108] As shown in FIG. 4, this exemplary embodiment provides a paging parameter determination method. The paging parameter determination method is applicable to a UE in a cellular mobile communication system and includes step 401.

[0109] In step 401, based on a non-active state extended discontinuous reception (eDRX) period, a period for the UE to monitor a radio access network (RAN) paging message and / or a core network (CN) paging message is determined.

[0110] According to the paging parameter determination method provided by an embodiment of the present disclosure, the period for the UE to monitor the RAN paging message and / or the CN paging message is determined based on the non-active state eDRX period. In this way, the UE can determine the period for monitoring the RAN paging message and / or the CN paging message based on the non-active state eDRX period, and the efficiency of determining the period for monitoring the paging message can be improved.

[0111] In one embodiment, the non-active state eDRX period is within a first value range or within a second value range, and the first value range is different from the second value range.

[0112] The time length of each non-active state eDRX period within the first value range is 10.24 seconds or less. When the non-active state eDRX period is within the first value range, a radio access network paging time window (RAN PTW) is not set for the UE.

[0113] The time length of each non-active state eDRX period within the second value range is greater than 10.24 seconds. When the non-active state eDRX period is within the second value range, RAN PTW is set for the UE.

[0114] In one embodiment, the method includes When the inactive state eDRX period is within a first value range and the UE has a core network paging time window (CN PTW), within the CN PTW, determining the minimum value among the inactive state eDRX period, the CN paging period, and the default paging period as the period for monitoring RAN paging messages and CN paging messages.

[0115] In one embodiment, the method includes: When the inactive state eDRX period is within a first value range and the UE has a CN PTW, outside the CN PTW, determining the inactive state eDRX period as the period for monitoring RAN paging messages.

[0116] In one embodiment, the method includes: When the inactive state eDRX period is within a first value range and the UE does not have a CN PTW, determining the minimum value among the inactive state eDRX period and the idle state eDRX period as the period for monitoring RAN paging messages and CN paging messages.

[0117] In one embodiment, the method includes: When the inactive state eDRX period is within a first value range, the UE has a CN PTW, and the CN PTW overlaps with the RAN PTW, within the CN PTW, monitoring RAN paging messages and CN paging messages.

[0118] In one embodiment, the method includes: When the inactive state eDRX period is within a second value range and the UE has a CN PTW, within the overlapping portion of the CN PTW and the RAN PTW, determining the minimum value among the RAN paging period, the CN paging period, and the default paging period as the period for monitoring RAN paging messages and CN paging messages.

[0119] In one embodiment, the method includes: When the inactive state eDRX period is within a second value range and the UE has a CN PTW, within the RAN PTW that does not overlap with the CN PTW, determining the RAN paging period as the period for monitoring RAN paging messages.

[0120] In one embodiment, the method includes: When the inactive state eDRX period is within the second value range, the method further includes determining a RAN PTW for monitoring RAN paging messages within the inactive state eDRX period based on the inactive state eDRX period.

[0121] In one embodiment, the method further includes determining a start position of the RAN PTW based on a preset rule, and determining an end position of the RAN PTW based on the start position and a time duration of the RAN PTW.

[0122] In one embodiment, the time duration of the RAN PTW is indicated by a base station.

[0123] In one embodiment, the method further includes receiving a RAN paging message including inactive state eDRX information.

[0124] Figure 5 As shown in , this exemplary embodiment provides a paging parameter determination method, the paging parameter determination method is applicable to a UE in a cellular mobile communication system, and includes steps 501 including.

[0125] Step 501 In, when the non-active state eDRX period is within a first value range, the RAN paging period is ignored.

[0126] The method disclosed in this embodiment can be executed by a UE in cellular mobile communication, and the UE can include a terminal such as a mobile phone that performs wireless communication by means of cellular mobile communication technology.

[0127] Here, the UE may be a UE in the inactive state. The UE monitors paging messages based on the paging period. The paging messages can include CN paging messages and RAN paging messages. In NR, a UE in the inactive state needs to receive paging messages, i.e., CN paging messages, from the core network, and also needs to receive paging messages from the RAN, i.e., RAN paging messages.

[0128] The RAN can set an inactive state eDRX period for the UE in the inactive state to further reduce the power consumption of the UE in the inactive state. The RAN can set the inactive state eDRX period of the UE via RRC signaling.

[0129] The time length of the inactive state eDRX period set by the RAN may be smaller than the time length of the eDRX period set by the core network.

[0130] The value range of the inactive state eDRX period may be the value range of the time length of the inactive state eDRX period.

[0131] The value range of the time length of the inactive state eDRX period may be {2.56 s, 5.12 s, 10.24 s, and 10.24 s or more}, where 10.24 s or more can include 20.48, 40.56, etc.

[0132] The paging parameters of the paging message for the UE in the inactive state can include, for example, the time domain resource setting parameters of the paging message. The time domain resource setting parameters can include, but are not limited to, the time window time domain position where the UE monitors the paging message, the period during which the UE monitors the paging message, etc. Here, the time window can include the CN PTW and / or the RAN PTW. The period during which the UE monitors the paging message can include the period during which the UE monitors the paging message within the paging time window and / or the period during which the UE monitors the paging message outside the paging time window.

[0133] For different value ranges of the inactive state eDRX period, the methods used by the base station to send paging messages are also different. For example, for the inactive state eDRX period within the first value range, the base station directly sends RAN paging messages according to the active state eDRX period. For the inactive state eDRX period within the second value range, the base station can set the RAN PTW within the inactive state eDRX period and send RAN paging messages at a certain period within the RAN PTW.

[0134] Therefore, the UE can determine the monitoring period of the paging message based on the duration of the inactive state eDRX period. The UE can monitor the paging messages sent from the core network and the receiving network respectively based on the determined monitoring period. For example, the UE can take the minimum value of the period during which the core network sends paging messages and the period during which the radio access network sends paging messages based on the inactive state eDRX period as the monitoring period of the paging message. In this way, the UE can simultaneously monitor the paging messages sent from the core network and the radio access network.

[0135] For the inactive state eDRX period within the first value range, since the base station directly transmits paging messages and the like according to the inactive state eDRX period, the RAN paging period is not used as the transmission period of the RAN paging message.

[0136] The first value range or the second value range may be determined based on the inactive state eDRX period set by the base station. When the inactive state eDRX period is within the first value range, the base station does not set the RAN PTW for the UE. When the inactive state eDRX period is within the second value range, the base station sets the RAN PTW for the UE.

[0137] For a long-duration inactive state eDRX period, the base station can set the RAN PTW within the inactive state eDRX period and transmit paging messages according to a certain period within the RAN PTW. For a short-duration inactive state eDRX period, the base station directly transmits paging messages and the like according to the inactive state eDRX period.

[0138] The first value range or the second value range may be determined based on the minimum time duration of the inactive state eDRX period required for the base station to set the RAN PTW.

[0139] Exemplarily, the first value range may be {2.56 s, 5.12 s, 10.24 s}, and the second value range may be 10.24 s or more, for example, {20.48 s, 40.96 s...}.

[0140] Exemplarily, when the time duration of the inactive state eDRX period is 10.24 s or less, the base station directly transmits the RAN paging message according to the inactive state eDRX period. When the time duration of the inactive state eDRX period is greater than 10.24 s, the base station can set the RAN PTW within the inactive state eDRX period and transmit the RAN paging message according to a certain period within the RAN PTW.

[0141] In this way, the UE can determine to ignore the RAN paging period based on the inactive state eDRX period, reducing the complexity of considering the RAN paging period in the process of determining the period for monitoring paging messages, and improving the efficiency of determining the period for monitoring paging messages.

[0142] In one embodiment, as shown in FIG. 6 As shown, the method further includes step 502 and In step 502 when the RAN paging period is ignored, based on the inactive state eDRX period, the UE determines the period for monitoring paging messages.

[0143] When the time length of the inactive state eDRX period is within a first value range, the base station directly transmits RAN paging messages according to the inactive state eDRX period. In this case, the UE needs to determine the period for monitoring paging messages based at least on the inactive state eDRX period.

[0144] When the UE only needs to monitor RAN paging messages, the period for monitoring RAN paging messages can be determined based only on the period for the base station to transmit RAN paging messages, that is, only on the inactive state eDRX period.

[0145] When the UE needs to monitor RAN paging messages and CN paging messages simultaneously, the UE needs to determine the periods for monitoring RAN paging messages and CN paging messages based on the inactive state eDRX period and the period for the core network to transmit CN paging messages. In this way, RAN paging messages and CN paging messages can be monitored simultaneously, reducing the missed listening of paging messages.

[0146] In this way, by determining the period for the UE to monitor paging messages in the inactive state based on the inactive state eDRX period, when the inactive state eDRX period is within the first value range, monitoring of paging messages is realized, the omission of paging messages is reduced, and communication efficiency is improved.

[0147] In one embodiment, the step of determining the period for the UE to monitor paging messages based on the inactive state eDRX period includes: in response to the UE having a CN PTW, within the CN PTW, determining the period for monitoring RAN paging messages and CN paging messages based on the inactive state eDRX period, the CN paging period, and the default paging period; and in response to the UE having a CN PTW, determining the inactive state eDRX period as the period for monitoring the RAN paging messages outside the CN PTW, including at least one of the steps.

[0148] When the UE has a CN PTW, within this CN PTW, the UE needs to monitor RAN paging messages and CN paging messages simultaneously.

[0149] The base station transmits RAN paging messages based on the inactive state eDRX period. Within the CN PTW, the core network transmits CN paging messages based on the CN paging period and the default paging period. The CN paging period can include a UE-specific cycle.

[0150] Therefore, when the UE monitors RAN paging messages and CN paging messages simultaneously within the CN PTW, it is necessary to determine the monitoring period based on the RAN paging period, the CN paging period, and the default paging period simultaneously.

[0151] In one embodiment, within the CN PTW, the step of determining the period for monitoring the RAN paging message and the CN paging message based on the inactive state eDRX period, the CN paging period, and the default paging period includes: within the CN PTW, determining the minimum value among the inactive state eDRX period, the CN paging period, and the default paging period as the period for monitoring the RAN paging message and the CN paging message.

[0152] The inactive state eDRX period, the CN paging period, and the default paging period can be in an integer multiple relationship. Therefore, by taking the minimum value among the inactive state eDRX period, the CN paging period, and the default paging period, the UE can monitor the paging message sent based on any one of the inactive state eDRX period, the CN paging period, and the default paging period.

[0153] Outside the CN PTW, the base station transmits the RAN paging message based on the inactive state eDRX period. Therefore, the UE can determine the inactive state eDRX period as the period for monitoring the RAN paging message. In this way, the UE can realize monitoring the RAN paging message outside the CN PTW.

[0154] In one embodiment, the step of determining the period for the UE to monitor the paging message based on the inactive state eDRX period includes: in response to the UE not having a CN PTW, determining the minimum value between the inactive state eDRX period and the CN paging period as the period for monitoring the RAN paging message and the CN paging message.

[0155] If there is no CN PTW, the base station transmits a RAN paging message based on the inactivity state eDRX cycle, and the core network transmits a CN paging message based on the CN paging cycle. Therefore, the UE can determine the minimum value of the inactivity state eDRX cycle and the CN paging cycle as the cycle for monitoring the RAN paging message and the CN paging message.

[0156] It can be made into a relationship where the inactivity state eDRX cycle is an integer multiple of the CN paging cycle. Therefore, when taking the minimum value of the inactivity state eDRX cycle and the CN paging cycle, the UE can monitor the paging message transmitted based on either one of the inactivity state eDRX cycle and the CN paging cycle. The omission of the paging message is reduced.

[0157] In one embodiment, the method is When the inactivity state eDRX cycle is within a second value range, determining a RAN PTW for monitoring the paging message within the inactivity state eDRX cycle based on the inactivity state eDRX cycle, where the first value range is different from the second value range.

[0158] In one embodiment, the method is When the inactivity state eDRX cycle is within a second value range, determining a cycle for the UE to monitor the paging message based on at least the RAN paging cycle, where the first value range is different from the second value range.

[0159] When the time length of the inactive state eDRX period is within the second value range, the base station can set the RAN PTW within the inactive state eDRX period. The base station transmits RAN paging messages according to the RAN paging cycle within the RAN PTW. Therefore, when the time length of the inactive state eDRX period is within the second value range, the UE needs to determine the period for monitoring paging messages based on at least the RAN paging cycle.

[0160] For example, when an inactive state UE needs to monitor CN paging messages and RAN paging messages simultaneously, the minimum value can be taken from the RAN paging cycle and the period for transmitting CN paging messages, and used as the period for monitoring CN paging messages and RAN paging messages.

[0161] The method for determining the RAN PTW based on the inactive state eDRX period may be specified by the communication protocol, or the method for determining the RAN PTW based on the inactive state eDRX period may be agreed upon by the base station and the UE.

[0162] One RAN PTW may be set within one inactive state eDRX period.

[0163] Exemplarily, the RAN PTW can be determined by the method of the base station indicating the time length of the RAN PTW and determining the start position of the RAN PTW according to a preset rule. The preset rule may be to determine the start position of the RAN PTW in the inactive state eDRX period using a preset algorithm based on at least the inactive state eDRX period and the identification information of the UE (for example, UE_ID_H). Furthermore, the end position of the RAN PTW is determined.

[0164] The base station and the UE can determine the RAN PTW using the same method. In this way, the base station and the UE can respectively transmit and monitor RAN messages at the same time domain position.

[0165] Within the RAN PTW, the base station can transmit RAN paging messages, and at the same time, the core network may also transmit CN paging messages. Therefore, within the RAN PTW, the UE may only monitor RAN paging messages, or may also monitor RAN paging messages and CN paging messages simultaneously.

[0166] If the UE needs to monitor only RAN paging messages, the monitoring period of the RAN paging messages can be determined based only on the period when the base station transmits RAN paging messages, that is, only the RAN paging period. If the UE needs to monitor RAN paging messages and CN paging messages simultaneously, the UE needs to determine the monitoring period of the RAN paging messages and CN paging messages based on the RAN paging period and the period when the core network transmits CN paging messages.

[0167] In one embodiment, when the non-active state eDRX period is within a second value range, the step of determining the period for the UE to monitor paging messages based at least on the RAN paging period is: In response to the UE having a CN PTW, within the CN PTW that overlaps with the RAN PTW, determining the period for monitoring RAN paging messages and CN paging messages based on the RAN paging period, the CN paging period, and the default paging period; In response to the UE having a CN PTW, within the RAN PTW that does not overlap with the CN PTW, determining the RAN paging period as the period for monitoring the RAN paging messages, including at least one of the above steps.

[0168] When the UE has a CN PTW and the CN PTW overlaps with the RAN PTW, within this CN PTW, the UE needs to monitor the RAN paging message and the CN paging message simultaneously.

[0169] Within the RAN PTW, the base station transmits RAN paging messages based on the RAN paging cycle. Within the CN PTW, the core network transmits CN paging messages based on the CN paging cycle and the Default Paging Cycle. The CN paging cycle can include a UE-Specific Cycle. Therefore, when the UE monitors the RAN paging message and the CN paging message simultaneously, it is necessary to determine the monitoring cycle based on the RAN paging cycle, the CN paging cycle, and the Default Paging Cycle.

[0170] In one embodiment, within the CN PTW that overlaps with the RAN PTW, the step of determining the cycle for monitoring the RAN paging message and the CN paging message based on the RAN paging cycle, the CN paging cycle, and the Default Paging Cycle includes: Within the CN PTW that overlaps with the RAN PTW, determining the minimum value among the RAN paging cycle, the CN paging cycle, and the Default Paging Cycle as the cycle for monitoring the RAN paging message and the CN paging message within the CN PTW.

[0171] The RAN paging cycle, the CN paging cycle, and the Default Paging Cycle can be in an integer multiple relationship. Therefore, by taking the minimum value among the RAN paging cycle, the CN paging cycle, and the Default Paging Cycle, the UE can monitor the paging message transmitted based on any one of the RAN paging cycle, the CN paging cycle, and the Default Paging Cycle.

[0172] Within the RAN PTW that does not overlap with the CN PTW, the base station transmits a RAN paging message based on the RAN paging period. Therefore, the UE can determine the RAN paging period as the period for monitoring the RAN paging message. In this way, the UE can be realized to monitor the RAN paging message within the RAN PTW that does not overlap with the CN PTW.

[0173] Figure 7 As shown in, this exemplary embodiment provides an information transmission method, and the paging parameter determination method is applicable to a cellular mobile communication system The first base station and includes step 701 .

[0174] Step 701 transmits inactivity state eDRX information for at least indicating the inactivity state eDRX period.

[0175] The inactive state eDRX information is for determining a period during which a user equipment (UE) monitors RAN paging messages and / or core network (CN) paging messages.

[0176] Here, the first base station may be the anchor base station or a non-anchor base station of the UE in the inactive state. Accordingly, the second base station may be the base station that performs data transmission with the first base station. For example, when the first base station is the anchor base station of the UE, the second base station is the non-anchor base station of the UE.

[0177] The anchor base station may be the base station where the UE enters the inactive state, and the anchor base station can set or store the related information of the UE in the inactive state, such as the inactivity state eDRX period, the RAN paging period, etc. for the UE.

[0178] The inactivity state eDRX information may be information associated with the inactivity state eDRX period. For example, the inactivity state eDRX information may indicate setting information for the UE to monitor paging messages in the inactivity state eDRX period. The inactivity state eDRX information is used to at least indicate the inactivity state eDRX period. The anchor base station can transmit the inactivity state eDRX period to the UE by transmitting the inactivity state eDRX information.

[0179] The anchor base station can transmit the setting information of the UE in the inactivity state, such as the inactivity state eDRX information, to the non-anchor base station.

[0180] Transmitting the inactivity state eDRX information can include the anchor base station transmitting the inactivity state eDRX information to the non-anchor base station and / or the non-anchor base station transmitting the inactivity state eDRX information to the anchor base station.

[0181] In one embodiment, a non-anchor base station determines the inactive state eDRX period set for the UE based on the inactive state eDRX information.

[0182] In one embodiment, in response to the inactive state eDRX period being within a first value range, the non-anchor base station obtains the inactive state eDRX period indicated by the received inactive state eDRX information.

[0183] In one embodiment, in response to the inactive state eDRX period being within a second value range, the non-anchor base station obtains the inactive state eDRX period and the RAN paging period indicated by the received inactive state eDRX information.

[0184] In one embodiment, the first value range is different from the second value range.

[0185] The time duration of each inactive state eDRX period within the first value range is 10.24 seconds or less. When the inactive state eDRX period is within the first value range, a radio access network paging time window (RAN PTW) is not set for the UE.

[0186] The time duration of each inactive state eDRX period within the second value range is greater than 10.24 seconds. When the inactive state eDRX period is within the second value range, a RAN PTW is set for the UE.

[0187] By transmitting the inactivity state eDRX information, the non-anchor base station can at least determine the inactivity state eDRX period set for the UE in the inactivity state. The same UE in the inactivity state is unknown The inactivity state eDRX period by using Reduces the situation of parameter communication errors.

[0188] In one embodiment, the step of transmitting the inactive state eDRX information includes transmitting, to the UE or the second base station, a RAN paging message including the inactive state eDRX information.

[0189] In one embodiment, the step of transmitting the non-active state eDRX information includes: transmitting a radio access network (RAN) paging message containing the transmission non-active state eDRX information to the UE; executing, with a second base station, transmission of a context request message containing the transmission non-active state eDRX information; executing, with a second base station, transmission of a context response message containing the transmission non-active state eDRX information.

[0190] The first base station and the second base station need to perform context interaction. In context interaction, the first base station and the second base station need to interact context request messages and context response messages.

[0191] When the UE is located within the coverage area of the first base station, the first base station can include the transmission non-active state eDRX information in the RAN paging message and transmit it to the UE. The UE can determine the non-active state eDRX period based on the non-active state eDRX information.

[0192] The first base station and the second base station need to perform context interaction. In context interaction, the first base station and the second base station need to interact context request messages and context response messages.

[0193] The first base station can send the inactive state eDRX information to the second base station included in a context request message or a context response message. In this way, on the one hand, the interaction of the inactive state eDRX information is realized, and on the other hand, the amount of information included in the context request message or the context response message is increased, and the information interaction efficiency is improved.

[0194] In one embodiment, in response to the inactive state eDRX period being within a first value range, the inactive state eDRX information is used to at least indicate the inactive state eDRX period. In response to the inactive state eDRX period being within a second value range, the inactive state eDRX information is used to at least indicate the inactive state eDRX period and the RAN paging period, where the first value range is different from the second value range.

[0195] The value range of the inactive state eDRX period may be the value range of the time length of the inactive state eDRX period.

[0196] The value range of the time length of the inactive state eDRX period may be {2.56 s, 5.12 s, 10.24 s, and 10.24 s or more}, where 10.24 s or more may include 20.48, 40.56, etc.

[0197] The first value range or the second value range may be determined based on the inactive state eDRX period set by the base station. When the inactive state eDRX period is within the first value range, the base station does not set the RAN PTW for the UE, and when the inactive state eDRX period is within the second value range, the base station sets the RAN PTW for the UE.

[0198] The first value range or the second value range may be determined based on the minimum time length of the inactive state eDRX period required for the base station to set the RAN PTW.

[0199] Exemplarily, the first value range may be {2.56 s, 5.12 s, 10.24 s}, and the second value range may be 10.24 s or more, for example {20.48 s, 40.96 s...}.

[0200] When the time length of the inactive state eDRX period is within the second value range, the base station can set the RAN PTW within the inactive state eDRX period. The base station transmits RAN paging messages according to the RAN paging cycle within the RAN PTW. Therefore, when the time length of the inactive state eDRX period is within the second value range, the UE needs to determine the period for monitoring paging messages based at least on the RAN paging cycle. Also, the method for determining the RAN PTW based on the inactive state eDRX period may be specified by a communication protocol, or the method for determining the RAN PTW based on the inactive state eDRX period may be agreed upon by the base station and the UE.

[0201] Therefore, when the time length of the inactive state eDRX period is within the second value range, the non-anchor base station needs to determine the period for transmitting paging messages based on the inactive state eDRX period and the radio access network paging cycle. The UE needs to determine the period for receiving paging messages based on the inactive state eDRX period and the radio access network paging cycle. Therefore, the anchor base station needs to indicate the inactive state eDRX period and the radio access network paging cycle to the non-anchor base station and / or the UE.

[0202] When the time length of the inactive state eDRX period is within the first value range, the base station directly transmits RAN paging messages according to the inactive state eDRX period. In this case, the UE needs to determine the period for monitoring paging messages based at least on the inactive state eDRX period. The base station or the UE can ignore the radio access network paging cycle.

[0203] Therefore, when the time length of the inactive state eDRX period is within the second value range, the non-anchor base station needs to determine the period for transmitting paging messages based on the inactive state eDRX period. The UE needs to determine the period for receiving paging messages based on the inactive state eDRX period. Therefore, the anchor base station needs to indicate the inactive state eDRX period to the non-anchor base station and / or the UE.

[0204] For a long-duration inactive state eDRX period, the base station can set the RAN PTW within the inactive state eDRX period and transmit paging messages at regular intervals within the RAN PTW. For a short-duration inactive state eDRX period, the base station directly transmits paging messages and the like according to the inactive state eDRX period.

[0205] The preset time length may be determined based on the minimum time length of the inactive state eDRX period required for the base station to set the RAN PTW.

[0206] Exemplarily, when the time length of the inactive state eDRX period is greater than 10.24 s, the base station can set the RAN PTW within the inactive state eDRX period and transmit RAN paging messages at regular intervals within the RAN PTW. When the time length of the inactive state eDRX period is 10.24 s or less, the base station directly transmits RAN paging messages according to the inactive state eDRX period. In this case, the preset time length is 10.24 s.

[0207] In one embodiment, the inactive state eDRX information is used to at least indicate the inactive state eDRX period and the RAN paging period.

[0208] Even if the time length of the inactive state eDRX period is within the first value range or within the second value range, the anchor base station can instruct the non-anchor base station and / or the UE of the inactive state eDRX period and the radio access network paging period. Distinguishing whether the inactive state eDRX period is within the first value range or the second value range is no longer necessary, and the complexity of transmitting the inactive state eDRX information is reduced.

[0209] In one embodiment, the method is decoding, in response to the first base station being a non-anchor base station and the inactive state eDRX period being within the first value range, the transmission inactive state eDRX period indicated by the received inactive state eDRX information, where the first value range is different from the second value range; further comprising decoding, in response to the first base station being a non-anchor base station and the inactive state eDRX period being within the second value range, the transmission inactive state eDRX period and the RAN paging period indicated by the received inactive state eDRX information.

[0210] When the time length of the inactive state eDRX period is within the second value range, the base station can set the RAN PTW within the inactive state eDRX period. The base station transmits RAN paging messages according to the RAN paging cycle within the RAN PTW. Therefore, when the time length of the inactive state eDRX period is within the second value range, the UE needs to determine the period for monitoring paging messages based at least on the RAN paging cycle. Also, the method for determining the RAN PTW based on the inactive state eDRX period may be defined by a communication protocol, or the method for determining the RAN PTW based on the inactive state eDRX period may be agreed upon between the base station and the UE.

[0211] Therefore, when the time length of the inactive state eDRX period is within the second value range, the non-anchor base station needs to determine the period for transmitting paging messages based on the inactive state eDRX period and the radio access network paging period. The UE needs to determine the period for receiving paging messages based on the inactive state eDRX period and the radio access network paging period. The non-anchor base station needs to determine the inactive state eDRX period and the radio access network paging period. Therefore, the non-anchor base station can decode the inactive state eDRX period and the radio access network paging period from the inactive state eDRX information.

[0212] When the time length of the inactive state eDRX period is within the first value range, the base station directly transmits RAN paging messages according to the inactive state eDRX period. In this case, the UE needs to determine the period for monitoring paging messages based on at least the inactive state eDRX period. The base station or the UE can ignore the radio access network paging period.

[0213] Therefore, when the time length of the inactive state eDRX period is within the second value range, the non-anchor base station needs to determine the period for transmitting paging messages based on the inactive state eDRX period. The UE needs to determine the period for receiving paging messages based on the inactive state eDRX period. The non-anchor base station can transmit RAN paging messages by only determining the inactive state eDRX period. Therefore, the non-anchor base station can decode only the inactive state eDRX period from the inactive state eDRX information.

[0214] The following provides a specific example in combination with any of the above embodiments.

[0215] 1. By introducing new parameters, the terminal changes the operation of receiving paging messages. a) The terminal is a non-active terminal, and b) The new parameter is a non-active state eDRX period.

[0216] 2. When the value range of the non-active state eDRX period set for the terminal is the second value range, the terminal needs to determine the paging parameters using both the RAN paging cycle and the non-active state eDRX period. a) The second value range is greater than 10.24 s, and b) As an example, it is as follows.

[0217] The value range of the RAN paging cycle is {rf32, rf64, rf128, rf256}, and the value range of the non-active state eDRX period set for the terminal is the second value range.

[0218] In this case, the terminal monitors the paging message according to the RAN paging cycle with RAN PTW, where RAN PTW is determined based on the non-active state eDRX period.

[0219] In this case, the terminal monitors the CN paging message and the RAN paging message simultaneously with CN PTW, where in the CN PTW window, the monitoring period needs to be determined by the RAN paging cycle.

[0220] As an example, the CN paging message and the RAN paging message can be monitored according to the period of min{default paging cycle, UE-specific cycle, RAN paging cycle}.

[0221] 3. When the value range of the non-active state eDRX period set for the terminal is the first value range, the terminal needs to ignore the set RAN paging cycle.

[0222] As an example, when the terminal is in this case (when the value range of the non-active state eDRX period is the first value range), it ignores the parameter value of the desired configured RAN paging period. a) The first value range is {2.56 s, 5.12 s, 10.24 s}, b) As an example, it is as follows.

[0223] 1) When there is a CN PTW setting: Outside the PTW window, monitor the paging message according to the non-active state eDRX period. Inside the CN PTW, monitor the CN paging message and the RAN paging message simultaneously. Here, in the CN PTW window, the monitoring period needs to be determined by the non-active state eDRX period. As an example, monitor the CN paging message and the RAN paging message according to the period of min{default paging cycle, UE-specific cycle, non-active state eDRX period}.

[0224] 2) When there is no CN PTW setting: As an example, monitor the CN paging message and the RAN paging message according to the minimum value of the CN eDRX period and the non-active state eDRX period.

[0225] 4. When transferring eDRX-related parameters between nodes, it is necessary to follow the following specifications. a) As an example, the eDRX-related parameters are used for message transfer between the anchor base station and the non-anchor base station of the non-active state UE. b) As an example, the transferred message may be a RAN paging message. c) As an example, the transferred message may be a UE context request / UE context response message. d) As an example, the attribute of the RAN paging period is selectable. When the value range of the inactive state eDRX period is the first value range, the anchor base station needs to transfer the RAN paging period and the inactive state eDRX period simultaneously. When the value range of the inactive state eDRX period is the second value range, the anchor base station only needs to transfer the inactive state eDRX period, and at this time, there is no need to transfer the RAN paging period between base stations. e) As an example, the attribute of the RAN paging period is required. When the value range of the inactive state eDRX period is the second value range, the non-anchor base station needs to decode and obtain the RAN paging period and the inactive state eDRX period simultaneously. When the value range of the inactive state eDRX period is the first value range, the non-anchor base station can decode and obtain only the inactive state eDRX period, and ignores the parameter of the RAN paging period.
