Description

[0001] This application is a divisional application of a Chinese application filed on December 8, 2021, with application number 202180004492.X and invention title "Information Processing Method and Device, Communication Equipment and Storage Medium". Technical Field

[0002] The present disclosure relates to the field of wireless communication technology but is not limited to the field of wireless communication technology, and particularly relates to an information processing method and device, communication equipment and storage medium. Background Art

[0003] A terminal, also known as a User Equipment (UE), after entering the RRC idle state, if the network side needs to send information to the UE, it can trigger the UE to switch back from the RRC idle state to the RRC connected state by sending a paging message.

[0004] In the related art, different UEs are configured to listen for paging messages at different paging occasions (POs). To further reduce the power consumption of the UE when listening for POs in the RRC idle state, paging early indication (PEI) is introduced. The UE can determine whether to listen for the PO by briefly listening for and decoding the PEI. And the listening for and decoding of the PO consume more power than the listening for and decoding of the PEI, thus further saving the power consumption of the UE.

[0005] However, it should be noted that: when the UE is in the RRC idle state, cell reselection may occur as the UE moves. After the RRC idle state UE switches to another cell, whether the UE still needs to be paged according to the PEI is a problem that needs to be further solved. Summary of the Invention

[0006] Embodiments of the present disclosure provide an information processing method and device, communication equipment and storage medium.

[0007] In a first aspect of the embodiments of the present disclosure, an information processing method is provided, which is executed by a UE, and the method includes:

[0008] Determine whether the UE listens for paging messages according to paging early indication (PEI) after cell reselection.

[0009] In a second aspect of the embodiments of the present disclosure, an information processing method is provided, which is executed by a core network device, and the method includes:

[0010] Send a notification message, where the notification message indicates whether the UE listens for paging messages according to the PEI after cell reselection.

[0011] A third aspect of the embodiments of the present disclosure is an information processing method, which is executed by a first base station, and the method includes:

[0012] Determine whether the UE listens for paging messages according to the paging early indication (PEI) after cell reselection.

[0013] A fourth aspect of the embodiments of the present disclosure provides an information processing device, and the device includes:

[0014] A first determination module, configured to determine whether the UE listens for paging messages according to the paging early indication (PEI) after cell reselection.

[0015] A fifth aspect of the embodiments of the present disclosure provides an information processing device, and the device includes:

[0016] A first sending module, configured to send notification information, where the notification information indicates whether the UE listens for paging messages according to the PEI after cell reselection.

[0017] A sixth aspect of the embodiments of the present disclosure provides an information processing device, which is executed by a first base station, and the device includes:

[0018] A second determination module, configured to determine whether the UE listens for paging messages according to the paging early indication (PEI) after cell reselection.

[0019] An eighth aspect of the embodiments of the present disclosure provides a communication device, including a processor, a transceiver, a memory, and an executable program stored in the memory and capable of running on the processor. When the processor runs the executable program, it executes the method for requesting a system message block provided in any one of the first to third aspects as described above.

[0020] A ninth aspect of the embodiments of the present disclosure provides a computer storage medium, which stores an executable program; after the executable program is executed by a processor, it can implement the method for requesting a system message block provided in any one of the first to third aspects as described above.

[0021] In the technical solution provided by the embodiments of the present disclosure, after the UE performs cell reselection, it will determine whether it is necessary to listen for paging messages according to the PEI. Compared with the situation where the UE does not determine whether to listen for paging messages according to the PEI after cell reselection and directly determines whether to listen for messages according to the original PEI configuration, it can at least reduce the phenomenon that the network side sends unnecessary wake-up of other UEs due to the paging of the UE after cell reselection, thereby reducing the wake-up of other UEs caused by listening for the same PEI and PO as the UE after cell reselection and the power consumption generated by the wake-up.

[0038] Please refer to Figure 1 , which shows a schematic structural diagram of a wireless communication system provided by the embodiments of the present disclosure. As Figure 1 shown, the wireless communication system is a communication system based on cellular mobile communication technology, and the wireless communication system may include: a plurality of UEs 11 and a plurality of access devices 12.

[0039] Among them, the UE 11 can be a device that provides voice and / or data connectivity for a user. The UE 11 can communicate with one or more core networks via a Radio Access Network (RAN). The UE 11 can be an Internet of Things (IoT) UE, such as a sensor device, a mobile phone (or called a "cellular" phone), and a computer with an IoT UE. For example, it can be a fixed, portable, pocket-sized, handheld, computer-integrated, or vehicle-mounted device. For example, a Station (STA), a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, an access point, a remote UE, an access terminal, a user terminal, a user agent, a user device, or a user equipment (UE). Or, the UE 11 can also be a device of an unmanned aerial vehicle. Or, the UE 11 can also be a vehicle-mounted device, such as a vehicle computer with wireless communication function, or a wireless communication device external to the vehicle computer. Or, the UE 11 can also be a roadside device, such as a street lamp, a signal lamp, or other roadside devices with wireless communication function, etc.

[0040] The access device 12 can be a network-side device in a wireless communication system. Among them, the wireless communication system can be a 4th generation mobile communication (4G) system, also known as the Long Term Evolution (LTE) system; or, the wireless communication system can also be a 5G system, also known as the new radio (NR) system or 5G NR system. Or, the wireless communication system can also be the next-generation system of the 5G system. Among them, the access network in the 5G system can be called the NG-RAN (New Generation - Radio Access Network, new generation wireless access network). Or, an MTC system.

[0041] Among them, the access device 12 can be an evolved access device (eNB) adopted in a 4G system. Alternatively, the access device 12 can also be an access device (gNB) with a centralized distributed architecture adopted in a 5G system. In response to the access device 12 adopting a centralized distributed architecture, it generally includes a central unit (CU) and at least two distributed units (DUs). The protocol stacks of the Packet Data Convergence Protocol (PDCP) layer, Radio Link Control (RLC) layer, and Media Access Control (MAC) layer are set in the central unit; the Physical (PHY) layer protocol stack is set in the distributed unit. The specific implementation manner of the access device 12 in the embodiments of the present disclosure is not limited.

[0042] A wireless connection can be established between the access device 12 and the UE 11 through 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; or, the wireless air interface is a wireless air interface based on the fifth-generation mobile communication network technology (5G) standard, such as the new air interface; or, the wireless air interface can also be a wireless air interface based on the standard of the next-generation mobile communication network technology of 5G.

[0043] In some embodiments, an E2E (End to End) connection can also be established between UEs 11. For example, scenarios such as vehicle-to-vehicle (V2V) communication, vehicle-to-infrastructure (V2I) communication, and vehicle-to-pedestrian (V2P) communication in vehicle-to-everything (V2X) communication.

[0044] In some embodiments, the above wireless communication system may further include a network management device 13.

[0045] A plurality of access devices 12 are respectively connected to a network management device 13. Among them, 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 also 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. The implementation form of the network management device 13 is not limited in the embodiments of the present disclosure.

[0046] As Figure 2 shown, an information processing method is provided in the embodiments of the present disclosure, where the method is executed by a UE, and the method includes:

[0047] S110: Determine whether the UE listens for a paging message according to a Paging Early Indicator (PEI) after cell reselection.

[0048] An RRC idle-state UE will determine whether to listen for a paging message according to the PEI after cell reselection. Here, the RRC idle state includes: an RRC inactive state and / or an RRC idle state.

[0049] For example, the UE may determine whether to listen for a paging message according to the PEI or not when it determines that it is a UE of a specific type or in a specific state according to the protocol. The specific type of UE includes, but is not limited to, a high-mobility UE, and the specific state of the UE includes, but is not limited to, a UE in an extended Discontinuous Reception (eDRX) state or a Power Saving Mode (PSM), and then determines whether to listen for a paging message according to the PEI or not.

[0050] Since the UE has performed cell reselection, to a certain extent, it indicates that the UE has moved. The area where the UE enters after moving may have a large number of UEs that need to listen for the same Paging Opportunity (PO) as this UE or a large number of UEs that are in the same paging group as this UE. If, at this time, the UE still listens for the paging message according to the PEI, the network side needs to wake up this UE and the UEs that listen for the same PO as this UE through the PEI. In this way, other UEs will be woken up by mistake, resulting in unnecessary power consumption waste of other UEs.

[0051] Thus, in the embodiments of the present disclosure, a determination is added on whether to monitor paging messages according to the PEI after the UE cell reselection, instead of continuing to monitor paging messages according to the PEI according to the configuration before the cell reselection, which can reduce the misawakening of other UEs.

[0052] As Figure 3A shown, an information processing method provided by an embodiment of the present disclosure includes:

[0053] S110A: Determine whether to monitor paging messages according to the PEI after the UE cell reselection according to the notification information sent by the network device.

[0054] In the embodiments of the present disclosure, the UE receives notification information sent by the network device, and the network device includes but is not limited to: a core network device and / or an access network device.

[0055] For example, after the UE reselects from cell A to cell B, it determines whether to monitor paging messages according to the PEI based on the notification information received from the core network or the access network before or after reselecting to cell B. Thus, the network side can determine whether the UE needs to monitor paging messages according to the PEI after cell reselection based on the number of UEs that need to monitor the same PO, and / or the mobility of the UEs to be paged and / or the paging probability, and considering the POs that different UEs between the two cells need to monitor, etc.

[0056] Exemplarily, the UE sends an attachment request to the network, and the network side sends an attachment response message in response to the attachment request. The notification information can be carried in the attachment response message. Thus, after the UE completes the attachment process or after completing the attachment, it can know whether it needs to monitor paging messages according to the PEI after cell reselection in the RRC disconnected state or at least in the RRC idle state according to the notification information sent by the network device.

[0057] As Figure 3B shown, an information processing method provided by an embodiment of the present disclosure includes:

[0058] S110B: Determine whether to monitor paging messages according to the PEI after the UE cell reselection according to the protocol agreement.

[0059] In some embodiments, which UEs need to monitor paging messages according to the PEI after cell reselection, and / or which UEs do not need to monitor paging messages according to the PEI after cell reselection can be pre-written into the communication protocol. Thus, both the UE and the network device will know whether the corresponding UE needs to monitor paging messages according to the PEI after cell reselection according to the protocol agreement in the communication protocol.

[0060] As an embodiment:

[0061] As an embodiment: The protocol stipulates the range of paging packets for whether the terminal uses the PEI to monitor paging messages after cell reselection. For example, for paging packet 0 and / or a UE without an allocated CN paging packet, it does not use the PEI to monitor paging messages after cell reselection.

[0062] As an embodiment: The protocol stipulates whether the terminal uses the PEI to monitor paging messages after cell reselection can be based on the paging packet scheme type. For example, a UE without a paging packet ID allocated by the core network does not use the PEI to monitor paging messages after cell reselection.

[0063] In some embodiments, the notification information sent by the network device includes:

[0064] A registration request completion message from the core network device and containing the notification information.

[0065] Exemplarily, when the UE sends a registration request, the network side will send a registration response message in response to the UE. The notification information can be carried in the registration response message. In this way, during or after the UE completes the registration process, it can know whether it needs to monitor paging messages according to the PEI after cell reselection in the RRC disconnected state or at least in the RRC idle state based on the notification information sent by the network device.

[0066] In some embodiments, the notification information indicates at least one of the following:

[0067] The UE does not monitor paging messages according to the PEI after cell reselection;

[0068] Or,

[0069] The UE monitors paging messages according to the PEI after cell reselection.

[0070] The notification information can include one or more bits, and these indication bits can indicate explicitly or implicitly that for the corresponding type of UE, the UE monitors paging messages according to the PEI after cell reselection, or the UE does not monitor paging messages according to the PEI after cell reselection.

[0071] If after the UE sends a cell reselection, it is known between base stations or between a base station and a core network device that the UE has sent a cell reselection, then it will be jointly determined according to the protocol convention known to both the UE and the network or the notification information sent to the UE whether it is necessary to send the PEI before paging the UE after the UE's cell reselection.

[0072] In some embodiments, the notification information includes:

[0073] An indication flag bit, where the indication flag bit indicates whether the UE listens for paging messages according to the PEI after cell reselection.

[0074] In some embodiments, the notification information may include one or more bit positions. Exemplarily, the notification information may include one bit position. The two bit values of this bit position can be used to indicate whether the UE needs to listen for paging messages according to the PEI after cell reselection. If the UE needs to listen for paging messages according to the PEI, the network device first sends the PEI before paging the UE, and the UE also listens for the PEI first, then determines whether to listen for the PO according to the listening result of the PEI, and determines whether the UE itself is paged by the network device according to whether the paging message received on the PO contains its own paging identifier.

[0075] In some embodiments, the notification information may include the range of paging groups:

[0076] For example, the notification information carries the paging groups that do not listen for paging messages according to the PEI after cell reselection. If the notification information indicates paging groups 0 - 3 at this time, it means that the network side allows the UEs in paging groups 0 - 3 to continue to use the PEI for paging message listening after cell reselection.

[0077] For example, the notification information carries the paging groups that listen for paging messages according to the PEI after cell reselection. If the notification information indicates paging groups 4 - 7, it means that the network side instructs the UEs in paging groups 4 - 7 not to use the PEI for paging message listening after cell reselection.

[0078] In some embodiments, the PEI includes:

[0079] The first type of PEI, where the first type of PEI indicates whether the UE needs to listen for the corresponding PO;

[0080] Or,

[0081] The second type of PEI, where the second type of PEI indicates whether to listen for the PO according to the paging group.

[0082] The first type of PEI here can be a general PEI, that is, this type of PEI is used for UEs that need to listen for one or more POs. Once these UEs listen for this PEI, they will determine whether to listen for the corresponding PO according to this PEI. The first type of PEI is a PEI that does not carry grouping information. This PEI can wake up all grouped users.

[0083] The first type of PEI here can only include one bit. The different bit values of this bit can indicate that all UEs that need to listen for a certain PO need to listen for the corresponding PO or do not need to listen for the corresponding PO.

[0084] The second type of PEI is the PEI for paging packets. UEs that need to monitor the same PO are divided into multiple paging packets. When the second type of PEI indicates whether a UE needs to monitor the corresponding PO, it can be indicated according to the paging packet. In this way, the second type of PEI can precisely indicate the paging packets that need to monitor the PO. And the paging packets can be determined according to the paging probability and / or mobility of the UE. For example, UEs included in the same paging packet have the same or similar paging probability and / or mobility. The second type of PEI may include multiple bits. For example, one bit can indicate whether UEs in at least one paging packet need to monitor the corresponding PO. If UEs that need to monitor a PO are divided into N paging packets, the second type of PEI may include N bits. When a second type of PEI is sent, the bit values of the N bits can be the same or different. The specific bit values depend on whether the network side needs the UEs in the corresponding paging packet to monitor the paging message on the corresponding PO.

[0085] In some embodiments, the method further includes:

[0086] In response to determining to monitor the paging message according to the PEI, monitor the paging message according to the monitoring result of the PEI;

[0087] Or,

[0088] In response to determining not to monitor the paging message according to the PEI, monitor the paging message on the paging occasion PO corresponding to the UE.

[0089] If the UE determines that it needs to monitor the paging message according to the PEI, the UE will first configure to monitor the PEI according to the PEI, and then determine whether to monitor the paging message on the corresponding PO according to the monitoring result of the PEI.

[0090] If the UE determines that it does not need to monitor the paging message according to the PEI, the UE will directly monitor the paging message on the corresponding PO and skip the monitoring of the PEI. When the network device pages the UE, it does not need to specifically send the PEI to wake up the UE to monitor the paging message, thereby reducing the situation that the sent PEI wakes up other UEs that do not need to monitor the paging message, and thus reducing the power consumption of other UEs.

[0091] As Figure 4 shown, an information processing method is provided in an embodiment of the present disclosure, where the method is executed by a core network device, and the method includes:

[0092] S210: Send notification information, where the notification information indicates whether the UE monitors the paging message according to the PEI after cell reselection.

[0093] The information processing method can be applied to a core network device and executed by the core network device. The core network device includes, but is not limited to, an Access Management Function (AMF).

[0094] The core network device can send notification information to the UE to inform the RRC non-connected state UE whether it needs to listen for paging messages according to the PEI after cell reselection. For example, at least inform the RRC idle state UE whether it needs to listen for paging messages according to the PEI after cell reselection.

[0095] In some embodiments, the notification information indicates at least one of the following:

[0096] The UE does not listen for paging messages according to the PEI after cell reselection;

[0097] Or,

[0098] The UE listens for paging messages according to the PEI after cell reselection.

[0099] In some embodiments, the notification information includes:

[0100] An indication flag bit, where the indication flag bit indicates whether the UE listens for paging messages according to the PEI after cell reselection.

[0101] The indication flag bit can be one or more bits and can be used to clearly indicate whether the UE listens for paging messages according to the PEI after cell reselection. In this way, the UE can simply know whether it needs to listen for paging messages according to the PEI after cell reselection based on this indication flag bit.

[0102] In some embodiments, the sending of the notification information includes:

[0103] Sending the notification information to the UE;

[0104] And / or,

[0105] Sending the notification information to the base station.

[0106] When the core network device sends notification information for a certain UE in the RRC non-connected state (abbreviated as non-connected state), it can directly send the notification information to the UE to tell the UE whether it needs to listen for paging messages according to the PEI after its own cell reselection. At the same time, the core network will also tell the base station whether it needs to page the UE according to the PEI when paging the corresponding UE. If it needs to page the UE according to the PEI, then before sending the paging message to the UE, it needs to first send the PEI. If it does not need to page the UE according to the PEI, then it can directly send the paging message to page the UE without sending the PEI.

[0107] When the core network device sends the notification information to the UE in the downlink direction, any non-access stratum (NAS) message can be used for the transmission. In some embodiments,

[0108] In some embodiments, the sending of the notification information to the UE includes:

[0109] Sending a registration request completion message containing the notification information to the UE.

[0110] For example, when the UE registers to the network, it will send a registration request message to the core network device. If the core network device allows the UE to register to the network, it will record the UE's information on the network side to complete the UE's registration on the network side, and send a registration request completion message to the UE after the registration is completed. In the embodiments of the present disclosure, the notification information is carried in the registration request completion message. In this way, after the UE completes the network registration, it will know whether it needs to monitor the paging message according to the PEI if a cell reselection occurs.

[0111] In some embodiments, the sending of the notification information to the base station includes:

[0112] Sending an Ng interface signaling containing the notification information to the base station.

[0113] The core network device can send the notification information to the base station with any signaling. Specifically, for example, the notification information is sent to the base station using any one of the Ng interface signaling.

[0114] Exemplarily, the Ng interface signaling includes:

[0115] Next-generation NG establishment response signaling;

[0116] Or,

[0117] Core network CN paging notification signaling;

[0118] Or,

[0119] Initial UE message notification signaling;

[0120] Or,

[0121] UE context modification signaling;

[0122] Or,

[0123] UE context establishment signaling.

[0124] By carrying the notification information in the above Ng interface signaling, signaling with other functions is multiplexed to transmit the notification information instead of using dedicated signaling for transmission, which has the characteristic of simple implementation.

[0125] In some embodiments, the core network device may of course also use a signaling for separately sending the notification information to inform the base station of the notification information.

[0126] In some embodiments, the notification information is for UEs in the entire cell, or for a single UE.

[0127] For example, if the notification information is carried in a UE context modification signaling or a UE context establishment signaling, it can be considered that the notification information is for a single UE, that is, per UE.

[0128] In summary, there are many ways for the core network device to send the notification information to the base station, and the specific implementation is not limited to any of the above.

[0129] As Figure 5 shown, an embodiment of the present disclosure provides an information processing method, which is executed by a first base station. The method includes:

[0130] S310: Determine whether the UE listens for paging messages according to the PEI after cell reselection.

[0131] Here, the first base station may be the anchor base station or non-anchor base station of the UE. In short, the first base station may be the base station that needs to page the UE.

[0132] Exemplarily, if the first base station itself is an anchor base station and the UE has a PEI configuration before, it may first send the PEI and then page the UE, that is, page the UE according to the PEI. If the first base station itself is not an anchor base station, that is, the first base station is a non-anchor base station, it may determine whether to send the PEI before paging the UE according to the determination result of whether the UE listens for paging according to the PEI after cell reselection.

[0133] As an embodiment, the first base station may be the base station that needs to page the UE. At this time, it may be because a CN paging message from the core network is received, or it may be a RAN paging for an inactive UE initiated by the base station.

[0134] As an embodiment, the anchor base station may be the base station that the terminal last received an RRC connection release message from; that is, the last used gNB or the last visited gNB.

[0135] As an embodiment: The base station first identifies whether it is allowed to continue using the PEI for this packet. If so: it is not necessary to determine whether it is the base station after cell reselection, and directly send the PEI before paging the UE;

[0136] As an example: The base station first identifies whether it is allowed to continue using the PEI for this packet. If not, it needs to determine whether it is the base station after reselection. Only the base station that is not after cell reselection sends the PEI before paging the user. For the base station after reselection, the PEI is not sent before paging the UE.

[0137] If the UE needs to listen for paging messages according to the PEI after cell reselection, then before paging the UE, the first cell needs to send the PEI downward and then send the paging message on the PO corresponding to the PEI. In this case, there is no need to determine whether the first cell that needs to send the paging message is the anchor cell.

[0138] If the UE does not need to listen for paging messages according to the PEI after cell reselection, it is necessary to determine whether the first cell is the anchor cell.

[0139] If the first cell is the anchor cell, the anchor cell first sends the PEI, and after sending the PEI, it sends the paging message for paging the UE on the corresponding PO..

[0140] If the first cell is not the anchor cell, when the first cell needs to page the UE, it can directly send the paging message for paging the UE on the PO where the UE needs to listen, and there is no need to send the PEI first before sending the paging message.

[0141] At this time, it can be considered that the use of the PEI is only in the anchor cell, and when the UE moves out of the anchor cell, the PEI will no longer be used to listen for paging messages.

[0142] As an example, the first base station can be the base station that needs to page the UE. At this time, it may be because it receives the CN paging message from the core network, or it may be the RAN paging message initiated by the base station for the non-active user.

[0143] As an example, the first cell under the first base station can be the cell that needs to page the UE.

[0144] As an example, the anchor cell is the cell where the terminal last received the RRC connection release message; that is, the last used cell or the last visited cell. As an example, the first base station will obtain the information of the anchor base station or the anchor cell from the core network. For example, the first base station receives the information from the core network to determine whether it is the anchor base station of the UE. As an example, the first base station will save the information of the anchor cell at the time of its release from the UE release history. In this way, the first base station will know whether there is an anchor cell of the UE in one or more cells formed by itself.

[0145] In some embodiments, determining whether the UE listens for paging messages according to the paging early indication (PEI) after cell reselection includes:

[0146] Determining whether the UE listens for paging messages according to the PEI after cell reselection based on the notification information sent by the core network device;

[0147] Or,

[0148] Determining whether the UE listens for paging messages according to the PEI after cell reselection according to the protocol agreement.

[0149] There are various ways for the first base station to specifically determine whether the UE needs to listen for paging messages according to the PEI after cell reselection, and the specific implementation is not limited to any of the above.

[0150] In some embodiments, if the core network device determines whether the UE needs to listen for paging messages according to the PEI after cell reselection according to the protocol agreement, it may send the notification information to the base station and the UE, or may not send the notification information to the UE, assuming that the base station and the UE will also determine by themselves according to the protocol whether the UE needs to listen for paging messages according to the PE after cell reselection.

[0151] In some embodiments, the notification information indicates at least one of the following:

[0152] The UE does not listen for paging messages according to the PEI after cell reselection;

[0153] Or,

[0154] The UE listens for paging messages according to the PEI after cell reselection.

[0155] If the notification information indicates that some UEs listen for paging messages according to the PEI after cell reselection, the UEs not indicated can determine whether to determine whether to listen for paging messages according to the PEI according to the prior configuration based on whether the UEs were configured to listen for paging messages according to the PEI before cell reselection.

[0156] If the notification information indicates that some UEs do not listen for paging messages according to the PEI after cell reselection, the UEs not indicated can determine whether to determine whether to listen for paging messages according to the PEI according to the prior configuration based on whether the UEs were configured to listen for paging messages according to the PEI before cell reselection.

[0157] In still some embodiments, the core network device will respectively indicate which UEs need to listen for paging messages according to the PEI after cell reselection, and will also indicate which UEs do not need to listen for paging messages according to the PEI after cell reselection.

[0158] In some embodiments, the notification information includes:

[0159] An indication flag bit, wherein the indication flag bit indicates whether the UE listens for paging messages according to the PEI after cell reselection.

[0160] The notification information may directly carry the indication flag bit, and the indication flag bit can explicitly indicate whether the UE listens for paging messages according to the PEI after cell reselection.

[0161] In some other embodiments, determining whether the UE listens for paging messages according to the paging early indication (PEI) after cell reselection includes at least one of the following:

[0162] In response to determining that the UE is allowed to listen for paging messages according to the PEI after the cell reselection, send the PEI before sending the paging message for paging the UE;

[0163] In response to determining that the UE is not allowed to listen for paging messages according to the PEI after the cell reselection, determine whether to send the PEI before sending the paging message for paging the UE according to whether the first base station is the anchor base station of the UE;

[0164] Or,

[0165] In response to determining that the UE is not allowed to listen for paging messages according to the PEI after the cell reselection, determine whether to send the PEI before sending the paging message for paging the UE according to whether the first cell under the first base station is the anchor cell of the UE.

[0166] In response to determining that the UE is not allowed to listen for paging messages according to the PEI after cell reselection, it can be determined whether to send the PEI before sending the paging message according to whether the current base station (i.e., the first base station) or the current cell (i.e., the first cell) is the anchor base station or anchor cell of the UE.

[0167] The first cell may be any cell under the first base station, and the "first" in the first cell does not specifically refer to but generally refers to any cell formed by the first base station.

[0168] The PEI here may be the aforementioned first type of PEI or the second type of PEI. Exemplarily, when it is determined that the UE is not allowed to listen for paging messages according to the PEI after the cell reselection, determining whether to send the PEI before sending the paging message for paging the UE according to whether the first base station is the anchor base station of the UE includes:

[0169] In response to determining that it is not allowed for the UE to monitor paging messages according to the PEI after cell reselection and the first base station is not the anchor base station of the UE, the PEI is not sent before sending the paging message for paging the UE.

[0170] Or,

[0171] In response to determining that it is not allowed for the UE to monitor paging messages according to the PEI after cell reselection and the first base station is the anchor base station of the UE, the PEI is sent before sending the paging message for paging the UE.

[0172] In some embodiments, the method further includes:

[0173] In response to the first base station being the anchor base station of the UE and determining that it is allowed for the UE to monitor paging messages according to the PEI after cell reselection, sending a paging message including PEI information and paging the non-active UE to a second base station, where the PEI information indicates that the second base station pages the non-active UE according to the PEI; or,

[0174] In response to the first base station being the anchor base station of the UE and determining that it is not allowed for the UE to monitor paging messages according to the PEI after cell reselection, sending a paging message including PEI information and paging the non-active UE to a second base station.

[0175] As an embodiment, the PEI-related information includes paging packet information sent by the core network to the terminal, and the terminal's support ability for the PEI, etc.

[0176] If the first base station is the anchor base station of the UE and it is allowed for the UE to monitor paging messages according to the PEI after cell reselection, then when the first base station sends a paging message for paging the non-active UE including PEI information to a second base station in the same Notification Area (NA) as the first base station, otherwise, a paging message not including PEI information is sent to the second base station.

[0177] In this way, it is possible to reduce the situation where, in order to page the UE, a paging message is sent to the second base station, and when the second base station pages the UE according to the PEI, other UEs are accidentally awakened due to the PEI.

[0178] The PEI information includes at least one of the following:

[0179] A PEI transmission indication, indicating whether to send the PEI before the second base station pages the non-active UE;

[0180] Paging packet information, indicating the paging packet of the non-active UE.

[0181] In some embodiments, in response to determining that it is not allowed for the UE to monitor paging messages according to the PEI after cell reselection, determining whether to send the PEI before sending the paging message for paging the UE according to whether the first cell is the anchor cell of the UE includes:

[0182] In response to determining that it is not allowed for the UE to monitor paging messages according to the PEI after cell reselection and the first cell is not the anchor cell of the UE, do not send the PEI before sending the paging message for paging the UE;

[0183] Or,

[0184] In response to determining that it is not allowed for the UE to monitor paging messages according to the PEI after cell reselection and the first cell is the anchor cell of the UE, send the PEI before sending the paging message for paging the UE.

[0185] If the first cell is the anchor cell of the UE and the UE is allowed to monitor paging messages according to the PEI after cell reselection, then if the first cell is the anchor cell, the paging message can continue to be sent according to the PEI, that is, first send the PEI and then send the paging message for paging the UE according to the previous configuration.

[0186] If the first cell is not the anchor cell of the UE, the phenomenon that the UE continues to use the PEI to wake up other UEs after cell reselection is reduced. At this time, if the first cell pages the UE, do not send the PEI, and directly send the paging message for paging the UE on the corresponding PO.

[0187] In this way, cell-level limitation on whether the UE continues to use the PEI to monitor paging messages after cell reselection is achieved.

[0188] In some embodiments, the PEI includes:

[0189] The first type of PEI, where the first type of PEI indicates whether the UE needs to monitor the corresponding PO;

[0190] Or,

[0191] The second type of PEI, where the second type of PEI indicates whether it is necessary to monitor the PO according to the paging grouping. For the relevant descriptions of the first type of PEI and the second type of PEI here, reference can be made to the foregoing embodiments, and details will not be repeated here.

[0192] In Long Term Evolution (LTE), when the UE moves out of the original cell, it will not use the PEI because the PEI will cause false alarms to other users using the PEI.

[0193] The higher the mobility of the UE, the greater the probability of false awakening of other UEs when listening to the PEI-based message after cell reselection. However, this also causes problems for this UE, that is, more power consumption is caused because the PEI cannot be used. However, in LTE, this problem is not significant because the mobility of eMTC UEs and NB-Iot UEs is inherently small. However, in the NR phase, the mobility of UEs is higher, so if the original solution is still followed, problems may occur. The network notifies the UE whether to use the PEI for listening to paging messages after cell reselection.

[0194] As an embodiment: The PEI includes a PEI carrying a paging packet function or a PEI not carrying a paging packet function.

[0195] The core network notifies the UE whether to use the PEI for listening to paging messages after cell reselection.

[0196] Method 1: The range of the paging packet in which the core network notifies the UE whether to use the PEI for listening to paging messages after cell reselection:

[0197] For example, for the first type of paging packet, assuming the first type of paging packet is 0 - 3, the UE is allowed to use the PEI for listening to paging messages after cell reselection. For example, the paging packets 0 - 3 can be paging packets with a relatively low paging probability. If a UE belonging to the paging packets 0 - 3 reselects to another cell, continuing to use the PEI will not cause too many problems for false awakening of other UEs, and is beneficial to power consumption saving of other UEs.

[0198] For example, for the second type of paging packet, assuming the paging packets are 4 - 7, the UE is allowed to use the PEI for listening to paging messages after cell reselection: The paging packets 4 - 7 can be UEs with a relatively high paging probability. At this time, continuing to use the PEI will cause too many problems for false awakening of other UEs, and is not beneficial to power consumption saving of other UEs.

[0199] The paging probability of the second type of paging packet here is higher than that of the first type of paging packet.

[0200] Method 2: The core network notifies the UE whether to continue to use the PEI for listening to paging messages after cell reselection of its currently grouped packet.

[0201] The core network uses a display flag bit to notify the UE whether to continue to use the PEI for listening to paging messages after cell reselection of its currently grouped packet:

[0202] Flag = 0: Do not continue to use the PEI for listening to paging messages after cell reselection:

[0203] Flag = 1: Continue to use the PEI for monitoring paging messages after cell reselection occurs.

[0204] Flag is one of the aforementioned display flag bits.

[0205] The core network notifies the UE whether to use the PEI for monitoring paging messages after cell reselection through the NAS procedure;

[0206] As an example: The core network notifies the UE to use the Registration request completion message.

[0207] The core network notifies the base station whether the user uses the PEI for monitoring paging messages after cell reselection.

[0208] As an example: The base stations and the core network negotiate through a Non UE-associated signaling procedure. Here, the Non UE-associated signaling can include, but is not limited to: interface signaling between network elements. If the interface signaling between network elements is used to negotiate whether the UE monitors paging messages according to the PEI after cell reselection, it can be for multiple UEs. For example, for all UEs of a certain type or for all UEs of a certain paging group. There are various types of interface signaling between network elements. For example, for the NR system, when the NG interface is established, the core network notifies the base station of the paging group auxiliary information through the NG SETUPRESPONSE.

[0209] As an example: The base stations and the core network negotiate through a UE-associated signaling procedure.

[0210] For example: For the NR system, for an idle UE, the core network notifies the base station whether the idle UE uses the PEI for monitoring paging messages after cell reselection through CN paging.

[0211] For example: For the NR system, for an inactive UE, the core network notifies the base station whether the user uses the PEI for monitoring paging messages after cell reselection through the initial UE message. The field indicating whether to monitor paging messages according to the PEI is carried in the RRC inactive assistance info; for subsequent base stations to use for RAN paging (paging) messages.

[0212] Based on the core network information, the base station decides whether to send the PEI when paging the UE at the current base station. The core network information includes, but is not limited to: the aforementioned core network information.

[0213] As an example: First, the base station identifies whether, for this paging packet, the UE is allowed to continue using the PEI to monitor paging messages after cell reselection. If so, the base station directly sends the PEI before paging the user without having to determine whether it is the base station after reselection.

[0214] As an example: First, the base station identifies whether the UE is allowed to continue using the PEI for this packet. If not, it is necessary to determine whether the current base station is the base station after reselection; only the non-reselected base station sends the PEI before paging the UE; for the reselected base station, the PEI is not sent before paging the UE.

[0215] Based on the core network information, the base station decides whether to send the PEI when paging the UE in the cell under the current base station. The core network information includes but is not limited to: the aforementioned core network information. At this time, the base station is an anchor base station or a non-anchor base station.

[0216] As an example: First, the base station identifies whether, for this paging packet, the UE is allowed to continue using the PEI to monitor paging messages after cell reselection. If so, the base station directly sends the PEI before paging the user in the cell under the current base station without having to determine that the cell under the current base station is the last used cell.

[0217] As an example: First, the base station identifies whether the UE is allowed to continue using the PEI for this packet. If not, it is necessary to determine whether the cell under the current base station is the reselected cell; at this time, only the non-reselected cell (last used cell) sends the PEI before paging the UE; for the reselected cell (i.e., non-last used cell), the PEI is not sent before paging the UE.

[0218] As an example: In the scenario of a non-active state UE, if the anchor base station decides to allow the UE to continue using the PEI, it will send a RAN paging message including the PEI information to the non-anchor base station; otherwise, the anchor base station will send a RAN paging message without the PEI information to the non-anchor base station.

[0219] The information of the core network and the UE / base station regarding whether to use the PEI for monitoring paging messages after cell reselection can be based on the implementation protocol agreement.

[0220] As an example: The protocol stipulates the scope of the paging packet regarding whether to use the PEI for monitoring paging messages after cell reselection for the UE, such as paging packet 0.

[0221] As an example: The protocol stipulates that whether the UE uses the PEI for paging message monitoring after cell reselection can be based on the packet scheme type. For example, users based on the UE-ID method do not use the PEI for paging message monitoring after cell reselection. At this time, all such UEs are emergency calls, and for a high paging probability, they may be paged at any time.

[0222] As an example: The protocol stipulates that whether the UE uses the PEI for paging message monitoring after cell reselection can be based on the paging message monitoring type. For example, UEs based on the e-DRX mode use the PEI for paging message monitoring after cell reselection.

[0223] As an example: The protocol stipulates that whether the UE uses the PEI for paging message monitoring after cell reselection can be based on the PEI monitoring type. For example, the ungrouped PEI (the first type of PEI) will cause a large number of false awakenings. Therefore, even if the UE is allowed to use the PEI for paging message monitoring after cell reselection, when it reselects to a base station or cell that sends the ungrouped PEI (i.e., the first type of PEI), it will no longer use the PEI for paging message monitoring.

[0224] As Figure 6 shown, an embodiment of the present disclosure provides an information processing device, where the device includes:
