Description

Information processing method, device and communication system Technical Field

[0001] The embodiments of the present application relate to the field of wireless communication technologies. Background Art

[0002] A large number of NR (New Radio) base stations have been deployed in the 3rd Generation Partnership Project (3GPP) standardized mobile communication technology networks. NR base stations require large bandwidths (e.g., 100 MHz), a large number of ports (e.g., 64T / 64R), and shorter time intervals (e.g., 1 ms). NR base stations consume significantly more energy than LTE base stations for functions such as baseband processing and digital front-ends.

[0003] According to operator statistics, the average energy consumption of an NR base station is more than three times that of an LTE base station. Nearly half of the cost of deploying 5G networks by operators is electricity expenses. More importantly, even in periods of no business, the energy consumption of NR base stations is still very high. This is because even when there is no business, NR base stations still need to send public signals, such as synchronization signal blocks (SSB), system information blocks (SIB, such as SIB1), system information (SI) and paging, which greatly reduces the energy efficiency of NR base stations. Network energy saving (NES) is an issue that needs to be addressed urgently.

[0004] It should be noted that the above introduction to the technical background is merely intended to provide a clear and complete description of the technical solutions of this application and facilitate understanding by those skilled in the art. Simply because these solutions are described in the background technology section of this application, it should not be assumed that the above technical solutions are well known to those skilled in the art.

[0005] Summary of the Invention

[0006] The inventors discovered that multiple user equipment (UEs) may coexist in a single cell. For example, UEs that do not support NES technology (non-NES UEs) and UEs that support NES technology (NES UEs) may coexist. Non-NES UEs can use traditional paging configuration information and / or methods to determine paging frames (PFs) and / or paging occasions (POs), while NES UEs can use NES-specific paging configuration information and / or methods to determine PFs and / or POs.

[0007] Non-NES UEs and NES UEs may have different PFs and / or POs, but it is currently unclear in which PFs and / or POs paging for non-NES UEs and / or paging for NES UEs is sent.

[0008] In order to solve at least one of the above problems or other similar problems, embodiments of the present application provide an information processing method, apparatus, and communication system.

[0009] According to one aspect of an embodiment of the present application, there is provided an information processing apparatus configured in a network device, the apparatus comprising:

[0010] A first sending unit, configured to send paging configuration information to a terminal device; and

[0011] The second sending unit is configured to send a paging message to the terminal device at the first paging time and / or the second paging time.

[0012] According to another aspect of an embodiment of the present application, there is provided an information processing apparatus configured in a terminal device, the apparatus comprising:

[0013] A first receiving unit, configured to receive paging configuration information sent by a network device; and

[0014] The second receiving unit is configured to receive a paging message sent by the network device at the first paging time and / or the second paging time.

[0015] According to another aspect of an embodiment of the present application, there is provided an information processing method, applied to a network device, the method comprising:

[0016] The network device sends paging configuration information to the terminal device; and

[0019] The terminal device receives the paging configuration information sent by the network device; and

[0020] The terminal device receives the paging message sent by the network device at the first paging time and / or the second paging time.

[0021] According to another aspect of an embodiment of the present application, a terminal device is provided, including a memory and a processor, wherein the memory stores a computer program, and the processor is configured to execute the computer program to implement the above-mentioned information processing method on the terminal device side.

[0022] According to another aspect of an embodiment of the present application, a network device is provided, including a memory and a processor, wherein the memory stores a computer program, and the processor is configured to execute the computer program to implement the above-mentioned information processing method on the network device side.

[0023] According to another aspect of an embodiment of the present application, a communication system is provided, including:

[0024] A network device that sends paging configuration information and sends a paging message at a first paging time and / or a second paging time; and

[0025] The terminal device receives the paging configuration information and receives the paging message sent by the network device at the first paging time and / or the second paging time.

[0026] One of the beneficial effects of the embodiments of the present application is that the network device sends paging configuration information and sends a paging message at the first paging time and / or the second paging time. Thus, when multiple terminal devices coexist, the network device can send a paging message in the paging frame and / or paging time associated with each terminal device, which helps reduce the processing complexity and possible signaling overhead of the network device, or helps reduce the power consumption and wireless resource occupancy rate of the network device. The method is simple and easy to implement.

[0070] For ease of description, the following description will be made using a base station as an example of an access network device. In the following description, "if ...", "under ..." and "when ..." can be used interchangeably without causing confusion.

[0071] The following describes the scenarios of the embodiments of the present application through examples, but the present application is not limited thereto.

[0072] FIG1 is a schematic diagram of a communication system according to an embodiment of the present application, schematically illustrating a situation taking a terminal device and a network device as an example. As shown in FIG1 , a communication system 100 may include a network device 101, a terminal device 102, and a terminal device 103. For simplicity, FIG1 illustrates only two terminal devices and one network device as an example, but the embodiments of the present application are not limited thereto.

[0073] In the embodiment of the present application, existing services or future services can be transmitted between the network device 101, the terminal device 102, and the terminal device 103. For example, these services may include, but are not limited to, enhanced mobile broadband (eMBB), massive machine type communication (mMTC), ultra-reliable and low-latency communication (URLLC), and related communications of terminal devices with reduced capabilities, etc.

[0074] Among them, terminal devices 102 and 103 can be in the RRC_IDLE state, the RRC_INACTIVE state, or the RRC_CONNECTED state. Terminal devices 102 and 103 can also communicate with network device 101. For example, taking terminal device 102 as an example, terminal device 102 can send data to network device 101 or retransmit data. Network device 101 can send a paging message to terminal device 102 or send data to terminal device 102, and terminal device 102 receives data sent by network device 101. In addition, different terminal devices can also communicate with each other. For example, terminal device 102 and terminal device 103 can exchange data.

[0075] It is worth noting that FIG1 shows that terminal device 102 and terminal device 103 are both within the coverage range of network device 101, but the present application is not limited thereto. Terminal device 102 and terminal device 103 may both be outside the coverage range of network device 101, or one of terminal device 102 and terminal device 103 may be within the coverage range of network device 101 and the other may be outside the coverage range of network device 101.

[0076] FIG2 illustrates a deployment scenario of an NES cell according to an embodiment of the present application. As shown in FIG2 , for example, an NES cell is co-deployed with a cell providing coverage, where the cell providing coverage may also be referred to as an anchor cell, and the NES cell may provide network capacity. For another example, an NES cell and a neighboring cell of the NES cell are co-deployed, and the NES cell and the neighboring cell of the NES cell may have completely overlapping coverage areas, partially overlapping coverage areas, or non-overlapping coverage areas. In FIG2 , communication can be performed between the NES cell and the anchor cell, between the NES cell and the neighboring cells of the NES cell, and between the anchor cell and the neighboring cells of the NES cell, for example, via an X2 interface or an F1 interface.

[0077] It is worth noting that FIG2 shows a terminal device in the NES cell, but the present application is not limited to this. The NES cell may also have more than one terminal device (UE). In addition, FIG2 shows that the terminal device is within the coverage of the NES cell, but the present application is not limited to this. The terminal device may also be outside the coverage of the NES cell. In addition, in FIG2, the anchor cell may also be co-deployed with one or more NES cells. An NES cell may have one or more neighboring cells, or may have no neighboring cells.

[0078] Figure 3 illustrates another deployment scenario for an NES cell according to an embodiment of the present application. As shown in Figure 3 , the NES cell is deployed standalone. It is worth noting that while Figure 3 illustrates a single terminal device in the NES cell, the present application is not limited to this. An NES cell may also contain more than one terminal device (UE). Furthermore, Figure 3 illustrates a terminal device within the coverage area of ​​the NES cell, but the present application is not limited to this. A terminal device may also be outside the coverage area of ​​the NES cell.

[0079] One of the work objectives of 3GPP Release 19 is shown in Table 1 below, namely, to specify the adaptation of common signal or channel transmission, including the adjustment of paging occasions, including limiting the paging occasions in the time domain.

[0080] Table 1

[0081] In a single cell, non-NES UEs and NES UEs may coexist. Non-NES UEs can use traditional paging frame (PF) and paging occasion (PO) calculation methods to determine PF and PO, while NES UEs can use their own specific methods to determine PF and PO.

[0082] Non-NES UEs and NES UEs may have different PFs and / or POs, but it is currently unclear in which PFs and / or POs paging for non-NES UEs and / or paging for NES UEs is sent.

[0083] To address at least one of the above problems, embodiments of the present application provide an information processing method, apparatus, and communication system.

[0084] Embodiments of the first aspect

[0085] An embodiment of the present application provides an information processing method, which is described from the perspective of a network device.

[0086] FIG4 is a schematic diagram of an information processing method according to an embodiment of the present application, which is applied to a network device. As shown in FIG4 , the method includes:

[0087] 401, the network device sends paging configuration information to the terminal device; and

[0088] 402. The network device sends a paging message to the terminal device at the first paging time and / or the second paging time.

[0089] It is worth noting that FIG4 above is merely a schematic illustration of an embodiment of the present application, and the present application is not limited thereto. For example, the execution order of the various operations may be appropriately adjusted, and other operations may be added or some operations may be reduced. Those skilled in the art may make appropriate modifications based on the above description, and are not limited to the description of FIG4 above.

[0090] According to the above embodiment, the network device sends paging configuration information to the terminal device and sends a paging message at the first paging time and / or the second paging time. Thus, when multiple terminal devices coexist, the network device can send a paging message in the paging frame and / or paging time associated with each terminal device, which helps reduce the processing complexity and possible signaling overhead of the network device, or helps reduce the power consumption and wireless resource occupancy of the network device. The method is simple and easy to implement.

[0091] For example, in an NES cell of a network device, non-NES UEs and NES UEs may coexist. The network device may send paging configuration information to the non-NES UEs and NES UEs. The paging configuration information may include NES paging configuration information for NES UEs and / or non-NES paging configuration information for non-NES UEs. The NES paging configuration information may correspond to a first paging time, and the non-NES paging configuration information may correspond to a second paging time.

[0092] When it is necessary to send a paging message, the network device may send the paging message at both the first paging time and the second paging time, or the network device may send the paging message only at the first paging time or the second paging time.

[0093] In the case where the network device sends the paging message at both the first paging time and the second paging time, taking a non-NES UE as an example, the non-NES UE can receive the paging message at the corresponding second paging time; taking a NES UE as an example, the NES UE can receive the paging message at the first paging time and / or the second paging time.

[0094] When the network device sends the paging message at the first paging time or the second paging time, taking a non-NES UE as an example, the non-NES UE can receive the paging message at the corresponding second paging time; taking a NES UE as an example, the NES UE can receive the paging message at the corresponding first paging time and / or the second paging time.

[0095] Therefore, in the NES cell of the network device, when non-NES UE and NES UE exist at the same time, the network device can send paging messages to the non-NES UE and the NES UE at corresponding paging times.

[0096] In some embodiments, the paging message may be a Paging message, which is used to find a terminal device in the RRC_IDLE state and the RRC_INACTIVE state to receive data of the called terminal; or the paging message may be a short message, which may be used to notify UEs in the RRC_IDLE state, the RRC_INACTIVE state, and the RRC_CONNECTED state about system information modifications and / or ETWS (Earthquake and Tsunami Warning System) / CMAS (Commercial Mobile Alert System) indications. Both the Paging message and the Short Message are addressed through the P-RNTI (Paging-Radio Network Temporary Identifier) ​​on the PDCCH, but the Paging message is sent on the PCCH, while the Short Message is sent directly through the PDCCH.

[0097] In some embodiments, a terminal device in the RRC_IDLE state monitors the PDCCH channel addressed to the P-RNTI to receive core network initiated paging (referred to as CN paging), while a terminal device in the RRC_INACTIVE state monitors the PDCCH channel addressed to the P-RNTI to receive RAN initiated paging (referred to as RAN paging) and CN paging. In addition, the terminal device can receive Short Messages by monitoring the PDCCH channel addressed to the P-RNTI. The terminal device does not need to monitor the paging channel continuously; it only needs to monitor the paging channel at one paging moment in a paging cycle.

[0098] In some embodiments, a terminal device in the RRC_CONNECTED state monitors the PDCCH channel addressed to the P-RNTI at least once at any paging time in each modification period to receive a Short Message indicating system information modification and / or ETWS, if the terminal device is provided with a common search space for monitoring paging on the active bandwidth part (active BWP).

[0099] A modification cycle may include one or more than one paging cycle.

[0100] In some embodiments, the paging configuration information may include at least one paging parameter. For example, the paging configuration information may include at least one of the following: a paging cycle, a radio frame offset, the number of paging frames in a paging cycle, the number of paging times in a paging frame, or a paging time offset. The present application is not limited thereto, and the paging configuration may also include other content.

[0101] This paging configuration information is used by the terminal device and / or network device to determine the paging frame and / or paging time. Determining the PF and / or PO refers to determining the PF and / or PO of at least one cell (e.g., a cell in a tracking area or a radio access network area, a cell with a system information change, or a cell with an ETWS / CMAS indication) in the network device (e.g., a gNB or gNB-DU).

[0102] In some embodiments, the network device may send paging messages at all first paging times and all second paging times of the first cell. Thus, the network device does not need to identify whether the paged UE is a non-NES UE or an NES UE, thereby reducing processing complexity and possible signaling overhead for the network device. The first cell may be an NES cell.

[0103] For example, the gNB sends paging messages for non-NES UEs and / or NES UEs in all PFs and / or POs in the NES cell. That is, when a paging message needs to be sent, regardless of whether the paging message is for a non-NES UE, an NES UE, or both a non-NES UE and an NES UE, the network device sends the paging message in all PFs and / or POs in the NES cell.

[0104] In some embodiments, paging messages for CN paging and / or RAN paging and / or indicating system information change and / or ETWS / CMAS notification may be sent in the above manner.

[0105] In some embodiments, only paging messages for indicating system information changes and / or ETWS / CMAS notifications, such as Short Messages (also referred to as short DCI or short paging messages, etc.), may be sent in the above manner.

[0106] Figure 5 is a schematic diagram of the information exchange process between a terminal device and a network device according to an embodiment of the present application. As shown in Figure 5, the network device determines a system information change or ETWS / CMAS notification and sends a paging message indicating the system information change and / or ETWS / CMAS notification at the first paging time and the second paging time.

[0107] For a non-NES UE, the non-NES UE may only monitor its own paging time, that is, the second paging time.

[0108] For NES UEs in RRC_IDLE or RRC_INACTIVE states, NES UEs can receive paging messages at the first paging time and / or second paging time corresponding to the paging configuration information. For example, the paging configuration information may include non-NES paging configuration information and NES paging configuration information. The NES UE can obtain its own NES PO (its own first paging time, i.e., the first paging time associated with its own UE identity) based on the NES paging configuration information and a specific PF / PO determination method, and receive paging messages at this NES PO. Alternatively, the NES UE can obtain its own non-NES PO or legacy PO (its own second paging time, i.e., the second paging time associated with its own UE identity) based on the non-NES paging configuration information and a legacy PF / PO determination method, and receive paging messages at this non-NES PO or legacy PO. Alternatively, the NES UE can also receive paging messages at both its own NES PO and legacy PO. For the specific content of the paging configuration information and the specific method of determining PF / PO based on the paging configuration information, please refer to the relevant technology and will not be described in detail here.

[0109] For NES UE, the NES UE in RRC_CONNECTED state can receive a paging message at one of the first paging moments and the second paging moments in a modification cycle (for example, receive a paging message at any one of all first paging moments and all second paging moments in a modification cycle), and the paging moment can be legacy PO and / or NES PO; or, the NES UE in RRC_CONNECTED state receives a paging message at a first paging moment (NES PO) in a modification cycle (for example, receive a paging message at any first paging moment (NES PO) in a modification cycle), or receives a paging message at a second paging moment (non-NES PO or legacy PO) in a modification cycle (for example, receive a paging message at any second paging moment (non-NES PO or legacy PO) in a modification cycle). The first paging time here, for example, is a PO (NES PO) obtained based on NES paging configuration information and a specific PF / PO determination method; the second paging time here, for example, is a PO (non-NES PO or legacy PO) obtained based on non-NES paging configuration information and a legacy PF / PO determination method. The PO that the NES UE receives paging from can be the NES UE's own PO or the PO of another NES UE.

[0110] In some embodiments, if the paging configuration information does not include NES paging configuration information related to the NES UE, the NES UE can obtain its own second paging radio frame / paging time (non-NES PF / PO or legacy PF / PO) based on the non-NES paging configuration information and the legacy PF / PO determination method, and / or obtain its own second paging radio frame / paging time based on the non-NES paging configuration information and the NES PF / PO determination method, and listen to its own paging message in the obtained PO.

[0111] Figure 6 illustrates the correspondence between paging messages, paging frames, and paging times in accordance with an embodiment of the present application. As shown in Figure 6, the paging cycle for a non-NES UE is 16 radio frames. A paging cycle includes N = 2 paging frames (T / 8), and each paging frame includes Ns = 2 paging times. The paging frames of an NES UE are offset by one radio frame relative to those of a non-NES UE, and a paging frame for a non-NES UE includes two paging times.

[0112] In other words, 4 POs for non-NES UEs and 4 POs for NES UEs are set in one paging cycle. When a paging message needs to be sent, the network device sends the paging message in 8 POs in one paging cycle.

[0113] In some embodiments, a network device may send a paging message for an NES UE in the PF and / or PO corresponding to the NES UE in an NES cell, and send a paging message for a non-NES UE in the PF and / or PO corresponding to the non-NES UE. By sending paging messages in the respective paging frames and / or paging times of the NES UE and the non-NES UE, the power consumption and radio resource utilization of the network device can be reduced.

[0114] For example, the network device may send a paging message at the first paging time or the second paging time based on the first information and / or first paging configuration information that the paged terminal device is a first terminal device (e.g., NES UE) or a second terminal device (non-NES UE).

[0115] The first paging configuration information may be paging configuration information from a core network device, or may be from other network devices (for example, the network device is a gNB, and the other network devices may be other gNBs located in the same RAN area as the gNB, which may also be referred to as adjacent gNBs; or the network device is a gNB-DU, and the other network devices may be gNB-CUs).

[0116] For example, if the paged terminal device is a first terminal device, the network device sends a paging message at a first paging time; and / or if the paged terminal device is a second terminal device, the network device sends a paging message at a second paging time.

[0117] For another example, if the first paging configuration information is associated with the first terminal device (for example, the first paging configuration information includes parameters associated with the first terminal device, etc.), the network device sends a paging message at the first paging time; and / or if the first paging configuration information is associated with the second terminal device (for example, the first paging configuration information includes parameters associated with the second terminal device, etc.), the network device sends a paging message at the second paging time.

[0118] Figure 7 is another schematic diagram illustrating the correspondence between paging messages, paging frames, and paging times in accordance with an embodiment of the present application. As shown in Figure 7, the paging cycle for a non-NES UE is 16 radio frames, with one paging cycle consisting of N = 2 paging frames (T / 8), and each paging frame consisting of Ns = 2 paging times. The paging frames of an NES UE are offset by one radio frame relative to those of a non-NES UE, and each paging frame for a non-NES UE includes two paging times.

[0119] In other words, four POs for non-NES UEs and four POs for NES UEs are set in one paging cycle. When a paging message needs to be sent to a non-NES UE, the network device sends the paging message at the four POs for non-NES UEs. For example, the network device may send the paging message at at least one of the four POs for non-NES UEs, where the PO may be a PO determined according to the paging configuration information.

[0120] When a paging message needs to be sent to an NES UE, the network device sends the paging message at the POs of the four NES UEs. For example, the network device may send the paging message at at least one of the POs of the four NES UEs, where the PO may be a PO determined according to the paging configuration information.

[0121] For a non-NES UE, the non-NES UE may only monitor its own paging time, that is, the second paging time.

[0122] For NES UEs in the RRC_IDLE or RRC_INACTIVE state, a NES UE can receive a paging message at the first paging time corresponding to the paging configuration information. For example, the paging configuration information may include both non-NES paging configuration information and NES paging configuration information. The NES UE can determine its own NES PO (first paging time) based on the NES paging configuration information and a specific PF / PO determination method, and receive a paging message at that NES PO.

[0123] For NES UE, the NES UE in RRC_CONNECTED state can receive a paging message at one of the first paging moments and the second paging moments in a modification cycle (for example, receive a paging message at any one of all first paging moments and all second paging moments in a modification cycle), and the paging moment can be legacy PO and / or NES PO; or, the NES UE in RRC_CONNECTED state can receive a paging message at a first paging moment (NES PO) in a modification cycle (for example, receive a paging message at any first paging moment (NES PO) in a modification cycle), or receive a paging message at a second paging moment (non-NES PO or legacy PO) in a modification cycle (for example, receive a paging message at any second paging moment (non-NES PO or legacy PO) in a modification cycle).

[0124] In some embodiments, if the paging configuration information does not include NES paging configuration information related to the NES UE, the NES UE can obtain its own second paging radio frame / paging time (non-NES PF / PO or legacy PF / PO) based on the non-NES paging configuration information and the legacy PF / PO determination method, and / or obtain its own second paging radio frame / paging time based on the non-NES paging configuration information and the NES PF / PO determination method, and listen for its own paging message in the obtained PO. In some embodiments, various methods can be used to let the network device know whether the paged UE is the first terminal device (e.g., NES UE) or the second terminal device (non-NES UE). The specific methods are exemplarily described below.

[0125] For paging initiated by the core network:

[0126] For a UE in the RRC_IDLE or RRC_INACTIVE state, the core network device may provide first indication information to the network device. The first indication information is used to indicate whether the terminal device being paged is the first terminal device (e.g., NES UE) or the second terminal device (non-NES UE) and / or the paging configuration of the terminal device being paged (i.e., first paging configuration information).

[0127] The network device may receive the first indication information from the core network device, and thereby determine whether the paged UE is an NES UE or a non-NES UE or determine in which PFs and / or POs to send the paging message according to the first indication information.

[0128] In some embodiments, the first indication information may be included in a paging message of the NGAP interface sent by the core network device to the network device. For example, the first indication information may be included in a UE Radio Capability for Paging IE, an Assistance Data for Paging IE, or a Paging Cause IE.

[0129] In some embodiments, the paging message of the NGAP interface also includes a paging message sent by the network device to the terminal device.

[0130] In some embodiments, the first indication information may indicate the first information by at least one of the following:

[0131] 1-bit information, terminal device identification, information of a terminal device group or terminal device set, or paging cause.

[0132] For example, the first information can be indicated by the value or presence of a 1-bit information. For example, a 1-bit information value of 1 indicates that the paged UE is an NES UE, while a 0-bit information value indicates that the paged UE is a non-NES UE; the reverse is also possible. For another example, the presence of a 1-bit information indicates that the paged UE is an NES UE; the absence of a 1-bit information indicates that the paged UE is a non-NES UE; the reverse is also possible.

[0133] For example, the terminal equipment identity may include a specific UE_ID, for example, the UE_ID may belong to a set of UE_IDs of NES UEs, or the UE_ID may belong to a set of UE_IDs of non-NES UEs.

[0134] Alternatively, the terminal device identifier may include a specific S-TMSI (temporary mobile user identifier, S-TMSI is, for example, the core network identifier of a terminal device registered with a mobility management entity (Mobility Management Entity, MME)), where the specific S-TMSI is, for example, a 5G-S-TMSI, which belongs to a specific 5G-S-TMSI set allocated to the NES UE.

[0135] For example, the information of the terminal device group or terminal device set may be that the terminal device group or terminal device set belongs to a paging group or paging set specific to an NES UE, that is, the UEs in the terminal device group or terminal device set are NES UEs.

[0136] For example, the paging cause may include a paging cause for paging an NES UE or a paging cause for paging a non-NES UE.

[0137] In some embodiments, the first indication information indicates the first paging configuration information by at least one of the following:

[0138] Paging cycle, radio frame offset, number of paging frames in a paging cycle, number of paging times in a paging frame, or paging time offset, etc.

[0139] The first paging configuration information is, for example, the paging configuration of the UE paged by the CN. For example, when the first paging configuration information includes parameters associated with the NES UE, the paged UE is the NES UE; when the first paging configuration information does not include parameters associated with the NES UE, the paged UE is the non-NES UE. For another example, the first paging configuration information may not explicitly indicate whether the parameters included therein are associated with the NES UE or the non-NES UE (for example, whether the parameters included in the first paging configuration information are associated with the NES UE or the non-NES UE is transparent to the base station), for example, the CN determines whether the paged UE is the NES UE or the non-NES UE, and then sends the corresponding first paging configuration information to the network device (for example, the gNB).

[0140] In some embodiments, the network device may receive first indication information from the core network device, thereby being able to determine the PF and / or PO for sending the paging message according to the first indication information.

[0141] For example, if the UE being paged is an NES UE or the gNB receives a paging configuration indicating an NES UE, the gNB may send a paging message to the PF / PO corresponding to the NES UE. If the UE being paged is a non-NES UE or the gNB receives a paging configuration indicating a non-NES UE, the gNB may send a paging message to the PF / PO corresponding to the non-NES UE.

[0142] For another example, the network device (such as gNB) can also obtain the paging radio frame and / or paging time based on the parameters included in the first paging configuration information and a specific calculation method, and send a paging message to the terminal device at the paging radio frame and / or paging time, where the specific calculation method can be, for example, the legacy PF / PO calculation method or the NES PF / PO calculation method.

[0143] In some embodiments, the network device may send a second indication message to the core network device, and the second indication message may include at least one of the following: information indicating whether the network device or the cell or tracking area of ​​the network device supports or uses the first paging, or information indicating whether it supports or uses the first paging configuration information of the paged terminal device.

[0144] The first paging may refer to paging related to the NES UE, and may also be referred to as paging in which the paged UE is a NES UE or NES paging.

[0145] For example, the gNB may indicate in advance to the CN whether the gNB supports or uses NES paging, or whether the gNB supports or uses the paging configuration of the paged UE. This indication may be included in an NG Setup request message, a RAN Configuration Update message, or an Uplink RAN ​​Configuration Transfer message.

[0146] In addition, the gNB may indicate in advance to the CN whether its cell or Tracking area supports or uses NES paging, or whether it supports or uses the paging configuration of the paged UE. For example, the gNB may indicate to the CN whether each of its cells or each Tracking area supports or uses NES paging, or whether it supports or uses the paging configuration of the paged UE.

[0147] Figure 8 is a schematic diagram of the information exchange process between a terminal device, a network device, and a core network device according to an embodiment of the present application. As shown in Figure 8, the CN sends a paging message including a UE indication (first indication information) to the gNB. The gNB can determine the PF and / or PO for sending the paging based on the first indication information in the received paging message and send the paging in the determined PF and / or PO. In addition, the gNB can send information to the CN indicating that it supports NES paging before receiving the paging message from the CN.

[0148] For paging initiated by the radio access network (RAN):

[0149] For a UE in RRC_INACTIVE state, the network device may store the context information (UE context) of the UE. The UE context may include information related to whether the UE is an NES UE. Therefore, when the network device receives downlink data from the CN for a UE in RRC_INACTIVE state, it may determine whether the paged UE is an NES UE (first information) based on the context information of the UE. Furthermore, the network device may determine the paging configuration information related to the UE (e.g., the paging configuration information sent by the network device to the UE) or the first paging configuration information (e.g., the paging configuration information sent by the gNB-CU to the gNB-DU; or the paging configuration information sent by the gNB to the neighboring gNB) based on the UE context.

[0150] Figure 9 is another schematic diagram of the information exchange process between a terminal device, a network device, and a core network device according to an embodiment of the present application. As shown in Figure 9, the CN sends downlink data for a UE to the gNB. The gNB can determine the PF and / or PO of the UE based on the stored context information of the UE and send a paging message in the determined PF and / or PO.

[0151] In some embodiments, since the network device does not know whether the UE in the RRC_INACTIVE state has moved to another network device (a second network device) within the same RAN area, the network device may send third indication information to the second network device. The third indication information may be used to indicate the first information and / or the first paging configuration information.

[0152] In some embodiments, the third indication information may be included in an access network paging (RAN paging) message of the Xn interface.

[0153] In some embodiments, the third indication information may indicate the first information by at least one of the following:

[0154] 1-bit information, terminal device identification, information of a terminal device group or terminal device set, context information of the terminal device, or paging reason.

[0155] For example, the first information may be indicated by the value of 1-bit information or whether it appears.

[0156] For example, the terminal equipment identity may include a specific UE_ID, for example, the UE_ID may belong to a set of UE_IDs of NES UEs, or the UE_ID may belong to a set of UE_IDs of non-NES UEs.

[0157] Alternatively, the terminal device identifier may include a specific S-TMSI (Temporary Mobile Subscriber Identity), which is, for example, a 5G-S-TMSI, and the 5G-S-TMSI may belong to a specific 5G-S-TMSI set allocated to the NES UE.

[0158] Alternatively, the terminal device identity may include a specific I-RNTI (Inactive Radio Network Temporary Identifier), which may belong to a specific set of I-RNTIs allocated to NES UEs.

[0159] For example, the information of the terminal device group or terminal device set may be that the terminal device group or terminal device set belongs to a paging group or paging set specific to an NES UE, that is, the UEs in the terminal device group or terminal device set are NES UEs.

[0160] For example, the paging cause may include a paging cause for paging an NES UE or a paging cause for paging a non-NES UE.

[0161] In some embodiments, the third indication information may indicate the first paging configuration information by at least one of the following:

[0162] Paging cycle, radio frame offset, number of paging frames in a paging cycle, number of paging times in a paging frame, or paging time offset.

[0163] If the first paging configuration information includes parameters associated with an NES UE, the paged UE is an NES UE; if the first paging configuration information does not include parameters associated with an NES UE, the paged UE is a non-NES UE. For another example, the first paging configuration information may not explicitly indicate whether the parameters included therein are associated with an NES UE or a non-NES UE. For example, the network device (e.g., gNB1) determines whether the paged UE is an NES UE or a non-NES UE and then sends the corresponding first paging configuration information to the second network device.

[0164] The second network device may use the received third indication information to determine the PF and / or PO for sending the paging.

[0165] For example, if the UE being paged is an NES UE or gNB2 (the second network device) receives the paging configuration indicating the NES UE sent by gNB1, gNB2 can send a paging message at the PF / PO corresponding to the NES UE. If the UE being paged is a non-NES UE or gNB2 (the second network device) receives the paging configuration indicating the non-NES UE sent by gNB1, gNB2 can send a paging message at the PF / PO corresponding to the non-NES UE.

[0166] For another example, gNB2 can also obtain the paging radio frame and / or paging time based on the parameters included in the first paging configuration information and a specific calculation method, and send a paging message to the terminal device at the paging radio frame and / or paging time, where the specific calculation method can be, for example, the legacy PF / PO calculation method or the NES PF / PO calculation method.

[0167] In some embodiments, the network device may receive fourth indication information sent by the second network device, and the fourth indication information may include at least one of the following: information indicating whether the second network device or the cell or tracking area of ​​the second network device supports or uses the first paging, or information indicating whether the first paging configuration information of the paged terminal device is supported or used.

[0168] For example, gNB2 may indicate in advance to gNB1 whether it supports or uses NES paging, or whether it supports or uses the paging configuration of the paged UE. This indication may be included in an Xn Setup Request message, an Xn Setup Response message, an NG-RAN Node Configuration Update message, an NG-RAN Node Configuration Update Acknowledge message, a Resource Status Request message, a Resource Status Response message, or a Resource Status Update message.

[0169] In addition, gNB2 may also indicate to gNB1 in advance whether its cell or Tracking area supports or uses NES paging, or whether it supports or uses the paging configuration of the paged UE. For example, gNB2 may indicate to gNB1 whether each of its cells or Tracking areas supports or uses NES paging, or whether it supports or uses the paging configuration of the paged UE.

[0170] Figure 10 is a schematic diagram of the information exchange process between network devices and core network devices in an embodiment of the present application. As shown in Figure 10, the CN sends downlink data for a UE to the first network device gNB1. gNB1 sends a RAN paging message including a UE indication (third indication information) to gNB2. gNB2 can determine the PF and / or PO to send the paging based on the third indication information in the received RAN paging message, and then send the paging in the determined PF and / or PO. In addition, gNB2 can send information to gNB1 indicating that it supports NES paging before receiving the RAN paging message.

[0171] In some embodiments, in a communication system, such as an NR system, a base station may have a split architecture, that is, the base station may include a centralized unit (CU) and a distributed unit (DU), wherein one CU may be connected to multiple DUs. An F1 interface is provided between the CU and the DU.

[0172] Taking the network device as a DU as an example, the network device may receive fifth indication information sent by a third network device (eg, a CU), where the fifth indication information is used to indicate the first information and / or the first paging configuration information.

[0173] In some embodiments, the fifth indication information may be included in a paging message of the F1AP.

[0174] In some embodiments, the fifth indication information may indicate the first information by at least one of the following:

[0175] 1-bit information, terminal device identification, information of a terminal device group or terminal device set, context information of the terminal device, paging reason, paging origin, or paging priority.

[0176] In some embodiments, the fifth indication information may indicate the first paging configuration information by at least one of the following:

[0177] Paging cycle, radio frame offset, number of paging frames in a paging cycle, number of paging times in a paging frame, or paging time offset.

[0178] In some embodiments, if the first paging configuration information includes parameters associated with an NES UE, the paged UE is an NES UE; if the first paging configuration information does not include parameters associated with an NES UE, the paged UE is a non-NES UE. Alternatively, the first paging configuration information may not explicitly indicate whether the included parameters are associated with an NES UE or a non-NES UE. For example, a third network device (e.g., a gNB-CU) determines whether the paged UE is an NES UE or a non-NES UE and then sends the corresponding first paging configuration information to the network device (e.g., a gNB-DU).

[0179] In some embodiments, the network device may use the received fifth indication information to determine the PF and / or PO for sending the paging.

[0180] For example, if the UE being paged is an NES UE or the gNB-DU (network device) receives a paging configuration indicating an NES UE from the gNB-CU (third network device), the gNB-DU can send a paging message to the PF / PO corresponding to the NES UE. If the UE being paged is a non-NES UE or the gNB-DU receives a paging configuration indicating a non-NES UE from the gNB-CU, the gNB-DU can send a paging message to the PF / PO corresponding to the non-NES UE.

[0181] For another example, the gNB-DU may also obtain a paging radio frame and / or a paging time based on the parameters included in the first paging configuration information and a specific calculation method, and send a paging message to the terminal device at the paging radio frame and / or the paging time, where the specific calculation method may be, for example, a legacy PF / PO calculation method or an NES PF / PO calculation method.

[0182] FIG11 is another schematic diagram illustrating the information exchange process between a terminal device and a network device according to an embodiment of the present application. As shown in FIG11 , the gNB-CU sends a paging message including a UE indication (fifth indication information) to the gNB-DU. The gNB-DU determines the PF and / or PO for sending the paging message based on the fifth indication information in the received paging message and sends the paging message to the terminal device using the determined PF and / or PO.

[0183] In some embodiments, the fifth indication information may also be used to indicate the first paging time or the second paging time. In other words, the third network device determines the PF and / or PO for sending the paging and includes the determined PF and / or PO in the fifth indication information. Thus, the network device can send the paging according to the determined PF and / or PO.

[0184] Figure 12 is another schematic diagram of the information exchange process between a terminal device and a network device according to an embodiment of the present application. As shown in Figure 12, the gNB-CU determines the PF and / or PO for sending the paging message, includes fifth indication information in the paging message of the F1AP, and indicates the PF and / or PO to the gNB-DU. The gNB-DU may determine the PF and / or PO for sending the paging message based on the fifth indication information in the received paging message and send the paging message to the terminal device using the determined PF and / or PO.

[0185] The above embodiments are merely exemplary of the present invention, but the present invention is not limited thereto. Appropriate modifications may be made based on the above embodiments. For example, the above embodiments may be used alone, or one or more of the above embodiments may be combined.

[0186] According to the above embodiment, the network device sends paging configuration information to the terminal device and sends a paging message at the first paging time and / or the second paging time. Thus, when multiple terminal devices coexist, the network device can send a paging message in the paging frame and / or paging time associated with each terminal device, which helps reduce the processing complexity and possible signaling overhead of the network device, or helps reduce the power consumption and wireless resource occupancy of the network device. The method is simple and easy to implement.

[0205] FIG14 is a schematic diagram of an information processing device according to an embodiment of the present application. As shown in FIG14 , the information processing device includes:

[0206] A first sending unit 1401 is configured to send paging configuration information to a terminal device; and
