Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a communication method, terminal, network device, computer program product and medium. Background Technology

[0002] In communication systems, packet data services from network devices (NDs) to user equipment (UEs) are often bursty, with data transmission occurring frequently for a period followed by longer periods of silence. From a latency perspective, constantly listening to the Physical Downlink Control Channel (PDCCH) to receive uplink scheduling or downlink data results in minimal latency. However, constantly listening to the PDCCH also leads to significant power consumption.

[0003] To address the trade-off between latency and power consumption, New Radio (NR) introduced the Wake-Upsignal (WUS) mechanism and paging grouping scheme to reduce the power consumption of electronic devices.

[0004] Network devices will send paging packets to multiple UEs that need to listen to the same paging occupancy (PO). If a target UE needs to be woken up to listen to the PO, the network device will wake up the packet containing the target UE. That is, only all UEs in the packet containing the target UE will be woken up, while UEs in other packets associated with the PO will not be woken up. This can reduce the false alarm rate caused by non-target UEs being woken up. However, a large number of non-target UEs in the same packet as the target UE will still be woken up, meaning that a large number of non-target UEs will still be in an invalid wake-up state, which will increase the power consumption of the UEs. Summary of the Invention

[0005] This application provides a communication method, terminal, network device, computer program product, and medium to solve the technical problem of increased device power consumption caused by existing wake-up signal mechanisms and paging grouping schemes.

[0006] To achieve the above objectives, the embodiments of this application adopt the following technical solutions:

[0007] Firstly, a communication method is provided, applied to a first terminal, which is a user terminal capable of interacting with network devices. The first terminal can be a mobile phone, tablet, etc., and the network device can be a base station, etc. The first terminal includes a main radio frequency receiver (MR) and a low-power wake-up receiver (LR), wherein the LR can listen to the low-power wake-up signal LP-WUS, and the MR can listen to the Early Paging Indication (PEI). This embodiment adopts a joint paging grouping scheme, performing LPWUS paging grouping on multiple UEs associated with the PO, with the LPWUS group number corresponding to the first terminal being the first group number. Performing PEI paging grouping on multiple UEs associated with the PO, with the PEI group number corresponding to the first terminal being the second group number. The group corresponding to the first group number includes the first terminal and other terminals, and the group corresponding to the second group number also includes the first terminal and other terminals, but the other terminals included in the group corresponding to the first group number are not entirely the same as those included in the group corresponding to the second group number.

[0008] Specifically, the first terminal listens for a first wake-up signal via a low-power wake-up receiver. This first wake-up signal carries first wake-up information, indicating the packet number of the first packet of the target terminal to be woken up. The packet number of the target terminal's first packet is the packet number obtained from LPWUS paging packets. The first terminal also listens for a second wake-up signal via a main radio frequency receiver. This second wake-up signal carries second wake-up information, indicating the packet number of the second packet of the target terminal. The packet number of the target terminal's second packet is the packet number from PEI paging packets. Both the packet number of the target terminal's first packet and the first terminal's first packet number are packet numbers obtained from LPWUS paging packets and are used only for distinction. Similarly, both the packet number of the target terminal's second packet and the second terminal's second packet number are packet numbers obtained from PEI paging packets and are used only for distinction. Furthermore, the number of target terminals that the network device needs to wake up may be one or more, and the number of the first packet number and the second packet number may also be one or more, but the number of the first packet number and the second packet number is always one.

[0009] If, based on the first wake-up signal and the second wake-up signal, the first terminal determines that the first group number of the target terminal to be woken up by the network device includes the first group number of the first terminal, and the second group number includes the second group number of the first terminal, then the first terminal can listen for paging messages. The first terminal can listen for paging messages at the corresponding paging time.

[0010] In order to ensure that the terminals found based on the first group number and the second group number are the target terminals and reduce the number of non-target terminals being woken up, the scheme for determining the first group number and the second group number of each terminal can be limited so that the first group number and the second group number are as orthogonal as possible.

[0011] The first group number includes: a first group baseline number and a first group offset. The first group baseline number is obtained based on the first identifier of the first terminal. The first group baseline number can refer to the changed portion of the parameters used to determine the first group number for the first terminal, while the first group offset can refer to the unchanged portion of the parameters used to determine the first group number for the first terminal. Alternatively, the first group baseline number is a variable associated with the first terminal, and the second group baseline number is a fixed value.

[0012] The second group number includes: a second group baseline number and a second group offset. The second group baseline number is obtained based on the second identifier of the first terminal. Similarly, the second group baseline number may refer to the changed portion of the parameters used to determine the second group number for the first terminal, and the second group offset may refer to the changed portion of the parameters used to determine the second group number for the first terminal.

[0013] The offset of the first group is the same as the offset of the second group, and the first identifier is different from the second identifier. In this way, the terminals included in the group corresponding to the first group number and the terminals included in the group corresponding to the second group number are as orthogonal as possible, thereby increasing the probability of identifying the first terminal from the intersection of the first group number and the second group number.

[0014] The characteristics of the target terminal's packet number are similar to those of the first terminal's packet number. The packet number of the target terminal's first packet includes a first packet baseline number and a first packet offset, and the packet number of the second packet includes a second packet baseline number and a second packet offset. The first packet offset is the same as the second packet offset, the first identifier is different from the second identifier, and the first packet baseline number obtained based on the first identifier is also different from the second packet baseline number obtained based on the second identifier.

[0015] Network devices use two types of paging packets for multiple terminals associated with a Pager (PO). By limiting the differences in the packet numbers of the two types of paging packets, the terminals corresponding to the first packet number and the second packet number can be made as orthogonal as possible. Before listening to the PO, the first terminal uses a first wake-up signal and a second wake-up signal to determine whether it is a terminal that the network device needs to wake up. This reduces the number of unpaging terminals that need to be woken up, lowering the false alarm rate and reducing device power consumption.

[0016] In one possible implementation of the first aspect, the first identifier is floor(UE_ID1 / (N*Ns)), and the second identifier is floor(UE_ID2 / (N*Ns)). Here, floor(*) is a floor function, N is the number of paging frames (PF) in one DRX period, and Ns is the number of paging times (PO) configured in one paging frame.

[0017] The first group number includes the first group baseline number, and the first identifier on which the first group baseline number is based is obtained by rounding down UE_ID1 / (N*Ns). Correspondingly, the second group number includes the second group baseline number, and the second identifier on which the second group baseline number is based is obtained by rounding down UE_ID2 / (N*Ns).

[0018] The first identifier involves two parameters: UE_ID1 and (N*Ns), and the second identifier involves two parameters: UE_ID2 and (N*Ns). (N*Ns) is a common fixed parameter, while UE_ID1 and UE_ID2 are the parameters that make the first identifier different from the second identifier.

[0019] The value of UE_ID2 is usually determined in a specific way. UE_ID2 is equal to the 5G-S-TMSI mod X of the first terminal, where X is usually 8192 or 32768.

[0020] UE_ID1 also uses a modulo method, equal to the third identifier of the first terminal mod Y. Both X and Y are multiples of 1024, and X is not equal to Y. UE_ID1 includes two parameters, namely the third identifier and Y. UE_ID2 includes two parameters, 5G-S-TMSI and X. Since X and Y are different, the third identifier can be the same as or different from 5G-S-TMSI.

[0021] The third identifier may include any one of the following: the 5G-S-TMSI of the first terminal, the 5G-TMSI of the first terminal, a portion of the 5G-S-TMSI of the first terminal, or the terminal identifier configured by the network device; the terminal identifier configured by the network device is different from UE_ID2, or in other words, the terminal identifier configured by the network device is different from GS-TMSI.

[0022] In this embodiment, both UE_ID1 in the first identifier and UE_ID2 in the second identifier are obtained using a modulo function, and different moduli are used. Thus, when UE_ID1 takes the modulus of the third identifier with Y as the modulus, regardless of whether the third identifier uses the same 5G-S-TMSI as UE_ID1, UE_ID1 and UE_ID2 will be different, thereby making the first identifier and the second identifier different. Therefore, the first group number determined based on the first identifier and the second group number determined based on the second identifier will also be different, effectively ensuring that different groups, including terminals, are as orthogonal as possible.

[0023] In one possible implementation of the first aspect, an alternative scheme for determining UE_ID1 is added. Specifically, the first identifier is floor(UE_ID1 / (N*Ns)), and the second identifier is floor(UE_ID2 / (N*Ns)). Here, floor(*) is a floor function, N is the number of paging frames (PF) in one DRX cycle, and Ns is the number of paging times (PO) configured in one paging frame.

[0024] UE_ID2 is equal to the 5G-S-TMSI of the first terminal mod X, where X is a multiple of 1024, and X is usually 8192 or 32768.

[0025] UE_ID1 is the third identifier of the first terminal and does not require modulo operation. Specifically, the third identifier can include any of the following: the first terminal's 5G-S-TMSI, the first terminal's 5G-TMSI, a portion of the first terminal's 5G-S-TMSI bits, or the terminal identifier configured by the network device. The terminal identifier configured by the network device is different from UE_ID2.

[0026] In this embodiment, UE_ID1 in the first identifier is obtained directly from the third identifier instead of using a modulo function, unlike the 5G-S-TMSI modulo scheme used for UE_ID. In this case, regardless of whether the third identifier is the same as the 5G-S-TMSI used by UE_ID1, UE_ID1 and UE_ID2 can be different, thus making the first identifier and the second identifier different. Therefore, the first group number determined based on the first identifier and the second group number determined based on the second identifier are also different, effectively ensuring that different groups, including terminals, are as orthogonal as possible.

[0027] In one possible implementation of the first aspect, an alternative scheme for determining the first identifier is added. Specifically, the first identifier is floor(UE_ID1 / Nh), and the second identifier is floor(UE_ID2 / (N*Ns)). Here, floor(*) is a floor function, N is the number of paging frames (PF) in one DRX cycle, and Ns is the number of paging times (PO) configured in one paging frame.

[0028] In this embodiment, the first identifier is obtained by rounding down UE_ID1 / Nh, and includes two parameters, namely UE_ID1 and Nh, where Nh is a random number configured by the network device, and Nh is not equal to N*Ns. Therefore, UE_ID1 can be equal to UE_ID2 or UE_ID2, both of which can make the first identifier and the second identifier different.

[0029] UE_ID1 can be equal to the third identifier of the first terminal mod Y. X can be equal to Y, or X can be different from Y.

[0030] The third identifier includes any one of the following: the 5G-S-TMSI of the first terminal, the 5G-TMSI of the first terminal, a portion of the 5G-S-TMSI of the first terminal, or the terminal identifier configured by the network device; the terminal identifier configured by the network device is different from UE_ID2; UE_ID2 is equal to the 5G-S-TMSI of the first terminal mod X; X and Y are both multiples of 1024.

[0031] In this embodiment, the parameter Nh in the first identifier is a random number assigned by the network device, and N*Ns in the second identifier is a fixed value, and Nh is not equal to N*Ns. UE_ID1 and UE_ID2 can be the same or different, both of which can make UE_ID1 and UE_ID2 different, thus making the first identifier and the second identifier different. Therefore, the first group number determined based on the first identifier and the second group number determined based on the second identifier are also different, effectively ensuring that different groups, including terminals, are as orthogonal as possible.

[0032] In one possible implementation of the first aspect, an additional scheme for determining the first identifier is added, where the first identifier also includes Nh configured by the network device. Specifically, the first identifier is floor(UE_ID1 / Nh), and the second identifier is floor(UE_ID2 / (N*Ns)). Here, floor(*) is a floor function, N is the number of paging frames (PF) in one DRX period, Ns is the number of paging times (PO) configured in one paging frame, and Nh is a random number configured by the network device, where Nh is not equal to N*Ns.

[0033] UE_ID1 is equal to the third identifier of the first terminal, which differs from the modulo scheme of UE_ID2 based on 5G-S-TMSI. Specifically, the third identifier includes any one of the following: the 5G-S-TMSI of the first terminal, the 5G-TMSI of the first terminal, a portion of the 5G-S-TMSI of the first terminal, or the terminal identifier configured by the network device; the terminal identifier configured by the network device is different from UE_ID2; UE_ID2 is equal to the 5G-S-TMSI of the first terminal mod X, where X is a multiple of 1024.

[0034] In this embodiment, the parameter Nh in the first identifier is a random number assigned by the network device, and N*Ns in the second identifier is a fixed value, and Nh is not equal to N*Ns. UE_ID2 is obtained by modulo operation, while UE_ID1 is directly equal to the third identifier. The identifiers can be the same or different, both of which will make UE_ID1 and UE_ID2 different, thus making the first identifier and the second identifier different. Therefore, the first group number determined based on the first identifier and the second group number determined based on the second identifier will also be different, effectively ensuring that different groups, including terminals, are as orthogonal as possible.

[0035] In one possible implementation of the first aspect, the method of obtaining Nh is further specified. The network device sends a combined packet message to the first terminal, which instructs the first terminal to listen for paging messages based on a first packet number and a second packet number. When sending the combined packet message, the network device carries Nh with it to the first terminal. The first terminal obtains Nh based on the combined packet message, calculates the UE's first packet number, and determines whether to listen for paging messages based on the first packet number.

[0036] In one possible implementation of the first aspect, the first terminal is in a radio resource control idle state or inactive state, controls the main radio frequency receiver to be in a turned-off state, and listens for the first wake-up signal through a low-power wake-up receiver.

[0037] The first group's group number includes the first group number, which is used to wake up the main RF receiver via a low-power wake-up receiver.

[0038] In one possible implementation of the first aspect, if the main radio frequency receiver is woken up before the listening time of the second wake-up signal configured by the network device, the second wake-up signal is listened to through the main radio frequency receiver.

[0039] In one possible implementation of the first aspect, the first packet offset is equal to a first difference between the total number of first PO packets and the number of first PO cell packets. The second packet offset is equal to a second difference between the total number of second PO packets and the number of second PO cell packets.

[0040] Wherein, the first PO group total number is the total number of LP-WUS groups corresponding to all UEs associated with each PO, and the first PO cell group number is the number of groups allocated by the cell in the LP-WUS groups corresponding to all UEs associated with each PO; the second PO group total number is the total number of PEI groups corresponding to all UEs associated with each PO, and the second PO cell group number is the number of groups allocated by the cell in the PEI groups corresponding to all UEs associated with each PO. The first difference equals the second difference.

[0041] In one possible implementation of the first aspect, the total number of first PO packets equals the number of first PO cell packets, and the first difference is equal to 0; the total number of second PO packets equals the number of second PO cell packets, and the second difference is equal to 0.

[0042] In one possible implementation of the first aspect, the first packet baseline number is obtained based on the first identifier using a first modulo function; the first modulo function is: first identifier modulo the number of packets in the first PO cell. The second packet baseline number is obtained based on the second identifier using a second modulo function; the second modulo function is: second identifier modulo the number of packets in the second PO cell.

[0043] In one possible implementation of the first aspect, the second wake-up signal is the Early Paging Indication (PEI) signal.

[0044] Secondly, a communication method is provided, applied to a network device. The network device sends a first wake-up signal; wherein the first wake-up signal is a low-power wake-up signal, the first wake-up signal carries first wake-up information, and the first wake-up information indicates the group number of the terminal of the first group that needs to be woken up.

[0045] The network device sends a second wake-up signal; wherein the second wake-up signal carries second wake-up information, the second wake-up information indicating the group number of the terminal of the second group that needs to be woken up.

[0046] The group number of the first group includes: the first group baseline number and the first group offset; the first group baseline number is obtained based on the first identifier of the terminal in the first group; the group number of the second group includes: the second group baseline number and the second group offset; the second group baseline number is obtained based on the second identifier of the terminal in the second group; the first group offset is the same as the second group offset, and the first identifier is different from the second identifier.

[0047] Network devices use two types of paging packets for multiple terminals associated with a Pager (PO). By limiting the differences in the packet numbers of the two types of paging packets, the terminals corresponding to the first packet number and the second packet number can be made as orthogonal as possible. Before listening to the PO, the first terminal uses a first wake-up signal and a second wake-up signal to determine whether it is a terminal that the network device needs to wake up. This reduces the number of unpaging terminals that need to be woken up, lowering the false alarm rate and reducing device power consumption.

[0048] In one possible implementation of the second aspect, the first identifier is floor(UE_ID1 / (N*Ns)), and the second identifier is floor(UE_ID2 / (N*Ns)). Here, floor(*) is a floor function, N is the number of paging frames (PF) in one DRX period, and Ns is the number of paging times (PO) configured in one paging frame.

The terminal identifier configured by the network device is different from UE_ID2; UE_ID2 equals the 5G-S-TMSI of the terminal in the second group mod X; X and Y are both multiples of 1024, and X is not equal to Y.

[0050] In one possible implementation of the second aspect, the first identifier is floor(UE_ID1 / (N*Ns)), and the second identifier is floor(UE_ID2 / (N*Ns)). Here, floor(*) is a floor function, N is the number of paging frames (PF) in one DRX period, and Ns is the number of paging times (PO) configured in one paging frame.

[0051] UE_ID1 is the third identifier of the terminal in the first group. The third identifier includes any one of the following: the 5G-S-TMSI of the terminal in the first group, the 5G-TMSI of the terminal in the first group, a portion of the 5G-S-TMSI of the terminal in the first group, or the terminal identifier configured by the network device; the terminal identifier configured by the network device is different from UE_ID2.

[0052] UE_ID2 is equal to the 5G-S-TMSI of the terminal in the second group mod X, where X is a multiple of 1024.

[0053] In one possible implementation of the second aspect, the first identifier is floor(UE_ID1 / Nh), and the second identifier is floor(UE_ID2 / (N*Ns)).

[0054] Where floor(*) is the floor function, N is the number of paging frames (PF) in one DRX period, Ns is the number of paging times (PO) configured in one paging frame, and Nh is a random number configured by the network device, Nh is not equal to N*Ns.

[0055] UE_ID1 is equal to the third identifier of the terminal in the first group mod Y; the third identifier includes any one of the following: the 5G-S-TMSI of the terminal in the first group, the 5G-TMSI of the terminal in the first group, a portion of the 5G-S-TMSI of the terminal in the first group, or the terminal identifier configured by the network device; the terminal identifier configured by the network device is different from UE_ID2; UE_ID2 is equal to the 5G-S-TMSI of the terminal in the second group mod X; X and Y are both multiples of 1024.

[0057] In one possible implementation of the second aspect, the first identifier is floor(UE_ID1 / Nh), and the second identifier is floor(UE_ID2 / (N*Ns)).

[0058] Where floor(*) is the floor function, N is the number of paging frames (PF) in one DRX period, Ns is the number of paging times (PO) configured in one paging frame, and Nh is a random number configured by the network device, Nh is not equal to N*Ns.

[0059] UE_ID1 is equal to the third identifier of the terminal in the first group; the third identifier includes any one of the following: the 5G-S-TMSI of the terminal in the first group, the 5G-TMSI of the terminal in the first group, a portion of the 5G-S-TMSI of the terminal in the first group, or the terminal identifier configured by the network device; the terminal identifier configured by the network device is different from UE_ID2; UE_ID2 is equal to the 5G-S-TMSI of the terminal in the second group mod X, where X is a multiple of 1024.

[0060] In one possible implementation of the second aspect, the communication method further includes:

[0061] Send a combined packet message; the combined packet message carries Nh, and the combined packet message instructs the terminal of the first packet to listen for paging messages based on the first packet number and the second packet number.

[0062] In one possible implementation of the second aspect, X equals 8192 or 32768.

[0063] In one possible implementation of the second aspect, the 5G-S-TMSI partial bits include either ng-5G-S-TMSI-Part1 or ng-5G-S-TMSI-Part2.

[0064] In one possible implementation of the second aspect, the terminal of the first group is in an inactive state of radio resource control, and the third identifier of the terminal of the first group includes either the radio network temporary long identifier I-RNTI-Value or the radio network temporary short identifier ShortI-RNTI-Value.

[0065] Alternatively, if the terminal in the second group is in an inactive state under Radio Resource Control, the third identifier of the terminal in the second group includes either the Radio Network Temporary Long I-RNTI-Value or the Radio Network Temporary Short I-RNTI-Value.

[0066] In one possible implementation of the second aspect, the first packet offset is equal to a first difference between the total number of first PO packets and the number of first PO cell packets. The second packet offset is equal to a second difference between the total number of second PO packets and the number of second PO cell packets.

The second packet baseline number is obtained based on the second identifier using a second modulo function; the second modulo function is: second identifier modulo the number of packets in the second PO cell.

[0070] In one possible implementation of the second aspect, the second wake-up signal is the Early Paging Indication (PEI) signal.

[0071] In one possible implementation of the second aspect, the network equipment includes a base station, which includes any one of an NB base station, an eNB base station, and a gNB base station.

[0072] Thirdly, a communication method is provided, applied to a first terminal, the first terminal including a main radio frequency receiver and a low-power wake-up receiver. The first terminal receives a first signaling sent by a network device; wherein, the first signaling includes a first packet number of the first terminal, the first packet number being a packet number configured by the network device for the first terminal.

[0073] A first terminal listens for a first wake-up signal via a low-power wake-up receiver. This first wake-up signal is a low-power wake-up signal and carries first wake-up information, indicating the group number of the first group of the target terminal to be woken up. If the group number of the first group includes the first group number, the first terminal listens for a second wake-up signal via a main radio frequency receiver. This second wake-up signal carries second wake-up information, indicating the group number of the second group of the target terminal. If the group number of the second group includes the second group number, the main radio frequency receiver listens for paging messages.

[0074] The communication method provided in this embodiment involves a network device configuring a first group number for a first terminal, and the first terminal calculating a second group number by determining the PEI calculation formula.

[0076] In one possible implementation of the third aspect, the first signaling is a radio resource connection control connection release signaling sent by the network device and received after the first terminal is powered on and registered.

[0077] Fourthly, a communication method is provided, applied to a network device. The network device sends a first signaling to a first terminal; wherein the first signaling includes a first packet number of the first terminal, the first packet number being a packet number configured by the network device for the first terminal.

The network device sends a second wake-up signal; wherein the second wake-up signal carries second wake-up information, the second wake-up information indicating the packet number of a terminal in a second packet to be woken up.

[0078] The communication method provided in this embodiment involves a network device configuring a first group number for a first terminal, and the first terminal calculating a second group number by determining the PEI calculation formula. This can make the first group number and the second group number as different as possible, thereby reducing the number of non-target terminals that are woken up, and lowering the false alarm rate and device power consumption.

[0079] In one possible implementation of the fourth aspect, the network device sends a first packet configuration parameter to the first terminal; the first packet configuration parameter includes the listening time for the first terminal to listen for a first wake-up signal. The network device then sends a second packet configuration parameter to the first terminal; the second packet configuration parameter indicates the listening time for the first terminal to listen for a second wake-up signal.

[0080] In one possible implementation of the fourth aspect, the first signaling is a radio resource connection control connection release signaling.

[0083] The processor executes computer execution instructions stored in memory, causing the terminal to perform a communication method such as that described in the first or third aspect.

[0084] In a sixth aspect, a network device is provided, the network device including a communication module, a memory and a processor, wherein the communication module and the memory are both coupled to the processor;

[0101] The following description, in conjunction with the accompanying drawings, illustrates exemplary embodiments of this application, including various details to aid understanding. These should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this application. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0102] To facilitate understanding, some technical common sense involved in the embodiments of this application will be introduced first.

[0103] User equipment (UE), also known as a terminal, refers to mobile phones, smart devices, electronic devices, streaming media devices, etc.

[0104] A network device (ND) is a device that provides a mobile communication network. Within the coverage area of ​​the mobile communication network provided by the network device, one or more UEs can access the mobile communication network and achieve communication.

[0105] Network devices interconnect various nodes such as servers, personal computers (PCs), and application terminals to form an information and communication network. Network devices can include information network equipment, communication network equipment, and network security equipment. Specifically, network devices can include: switches, routers, firewalls, bridges, hubs, gateways, Virtual Private Network (VPN) servers, Network Interface Cards (NICs), Wire Access Points (WAPs), modems, 5G base stations, optical transceivers, fiber optic transceivers, and optical cables. Alternatively, network devices can also include evolved NodeBs (eNodeBs or eNBs) in Long Term Evolution (LTE) systems, Wireless Access Point Controllers (WAPCs) in Cloud Radio Access Network (CRAN) scenarios, access network equipment for user equipment, or access network equipment in future Public Land Mobile Networks (PLMNs), without limitation.

[0106] Mobile communication networks can be divided into three parts: the base station subsystem, the network subsystem, and the system support system. The network subsystem includes the core network (CN) and the access network (AN). The core network includes the Mobile Switching Center (MSC), and the base station subsystem includes the Base Station Controller (BSC). The interface between the BSC and the MSC is the A-port. The A-port can transmit control signals and voice data from the MSC to the base station, and simultaneously transmit signals and data from the base station back to the MSC.

[0107] The base station subsystem sends call requests or data requests through interface A. The core network connects the call requests or data requests received through interface A to different networks before transmitting them to the corresponding UE. The BSC can also receive instructions from the MSC to control the allocation of radio resources, call processing, and management of radio interfaces.

[0108] like Figure 1The diagram illustrates a possible network architecture. This architecture can include a core network (CN), base stations, and users (UEs). Multiple base stations can be interconnected, allowing any transmission failure between two base stations to be handled by other base stations, thus enhancing network robustness. Base stations can be NodeBs of 3G, eNodeBs (eNBs) of 4G, or gNodeBs (gNBs) of 5G, without limitation. As physical access nodes in the Next Generation Radio Access Network (NG-RAN), base stations are used to connect UEs to the core network.

[0109] The core network may include Access Gateways (AGWs) for controlling and coordinating cooperation between base stations. Access Gateways may include Service Gateways (SGWs) and Packet Gateways (PGWs). The AMF (Automatic Modem) is one of the core network elements of 5G NR, primarily responsible for UE access and mobility management, handling UE access control, including UE authentication, security policies, and mobility management. The AMF is also responsible for establishing and maintaining a secure tunnel between the UE and the SMF, providing a session management message transmission channel for the UE and SMF, providing authentication and authorization functions for user access, and serving as the access point between the UE and the core network control plane to ensure secure data transmission.

[0110] 5G is a new generation of broadband mobile communication technology with features such as high speed, low latency and massive connectivity. 5G communication facilities are the network infrastructure for realizing the interconnection of people, machines and things.

[0111] 5G New Radio (NR) is a 5G network technology based on a new air interface design using Orthogonal Frequency Division Multiplexing (OFDM), providing user equipment with faster speeds, lower latency, and higher capacity for communication.

[0112] The 5G NR wireless protocol stack is divided into two planes: the User Plane (UP) and the Control Plane (CP). The User Plane protocol stack contains the protocol suite used for user data transmission, while the Control Plane protocol stack contains the protocol suite used for system control signaling transmission. The User Plane protocol stack, from top to bottom, includes: Service Data Adaptation Protocol (SDAP) layer, Packet Data Convergence Protocol (PDCP) layer, Radio Link Control (RLC) layer, Medium Access Control (MAC) layer, and Physical (PHY) layer.

[0113] like Figure 2 As shown, the control plane protocol stack, from top to bottom, includes: Non-Access Stratum (NAS) layer, Radio Resource Contocol (RRC) layer, Packet Data Convergence Protocol (PDCP) layer, Radio Link Control (RLC) layer, Medium Access Control (MAC) layer, and Physical (PHY) layer.

[0114] On the UE side, the control plane protocol stack is located within the UE. On the network side, RRC, PDCP, RLC, MAC, and PHY are located within the base station, while NAS is located in the Access and Mobility Management Function (AMF) of the core network.

[0115] RRC is a layer in the 5G NR protocol stack. RRC mainly implements the functions of connection establishment and release, and is responsible for system information broadcasting, radio bearer establishment, RRC reconfiguration and release, paging notification and release, etc.

[0116] RRC is responsible for establishing, maintaining, and releasing the RRC connection between the UE and the base station. In 5G NR, after the RRC connection is established and before the RRC is released, the UE attaches, suspends, resumes, and detaches from the mobile communication network at different stages. Different network connection states of the UE correspond to different RRC states.

[0117] The RRC states of a UE mainly include: RRC Idle (RRC_IDLE), RRC Connected (RRC_Connected), and RRC Inactive (RRC_Inactive). When a UE is in RRC_Connected, it is in an active state, and the UE has acquired radio resources.

[0118] When a UE is in an RRC_IDLE or RRC_Inactive state (i.e., inactive), it is not acquiring radio resources. While inactive, a UE can listen for network information via paging and acquire radio resources according to the network's instructions. Paging refers to network devices sending paging information to UEs in the RRC_IDLE or RRC_Inactive state. Network devices sending paging messages can include the core network and base stations.

[0119] like Figure 3 The diagram illustrates a network topology for paging a UE using a network device. The network device is configured with multiple Discontinuous Reception (DRX) cycles, such as DRX1, DRX2, etc. The duration of different DRX cycles can be the same or different. Figure 3 The cycle lengths of DRX1 and DRX2 shown can be 320ms.

[0120] The network device is configured with the number of paging radio frames (PF) per DRX and the number of paging occasions (PO) per PF. For example... Figure 3 As shown, both DRX1 and DRX2 include 4 PFs, namely PF1, PF2, PF3 and PF4, and each PF includes two POs, namely PO0 and PO1.

[0121] Network devices typically configure each PO (Point of Purchase) to associate with multiple UEs, and on a single PF, UEs associated with different POs are not duplicated. For example... Figure 3 As shown, PO0 is associated with ue1, ue2, ue3, ue4, ue5, ue6, ue7...ueA, and PO1 is associated with ue11, ue12, ue13, ue14, ue15, ue16, ue17...ueB. It should be noted that the DRX cycle duration, the number of PFs and POs, and the number of UEs associated with each PO are all illustrative examples and are not intended to limit the specific implementation.

[0122] When a Page Point (PO) arrives at its corresponding Power Provider (PF), each UE listens for a Paging-Radio Network Temporary Identifier (P-RNTI) on the Physical Downlink Control Channel (PDCCH). Upon detecting the P-RNTI, the UE determines whether a paging message is carried on the corresponding Physical Downlink Shared Channel (PDSCH). If the UE parses the P-RNTI from the PDCCH, it receives the data on the PDSCH according to the parameters indicated on the PDCCH, i.e., it receives the paging message. Specifically, the UE listens for the P-RNTI-scrambled DCI1_0 at the PO and receives the paging message through the time-frequency domain location indicated by DCI1_0.

[0123] The UE receives and decodes the paging message to obtain a list of user identifiers (UE IDs). This list contains the user identifier of the UE actually being paged by the network device. For ease of description, the UE actually being paged by the network device is referred to as the target UE. In other words, the UE receives and decodes the paging message, obtains the user identifier of the target UE from the UE ID list contained in the paging message, and if it determines that the user identifier of the target UE in the UE ID list includes the UE's own user identifier, the UE can identify that this UE is the target UE actually being paged by the network device.

[0124] like Figure 3 As shown, each PO (Point of Purchase) typically associates with a group of UEs, all of whom need to listen to that PO. Within this group of POs, only some UEs are actually the target UEs being paged by the network device. For ease of description, the UEs in this group other than the target UEs are referred to as non-target UEs. All UEs in this group, whether target or non-target, need to listen for paging messages at their respective POs, receive and decode the paging messages, and determine whether they are being paged by the network device based on the user identifier of the target UE in the UE ID list.

[0125] In the group of PEs associated with the PO, the target device receives and decodes the paging message, detects its own user identifier in the decoded paging message, and performs the networking operation indicated by the paging message. Non-target UEs receive and decode the paging message, but do not detect their own user identifier in the decoded paging message and do not need to perform the networking operation indicated by the paging message. For non-target UEs, performing the operation of receiving and decoding the paging message increases device power consumption, leading to false alarms. In other words, the existing PO monitoring mechanism has a technical problem of a high false alarm rate.

[0126] To address the technical issue of high false alarm rates caused by waking up multiple non-target UEs in the PO monitoring mechanism, network devices can also add a grouping scheme based on Paging Early Indication (PEI). This grouping of multiple UEs associated with the PO will enable more accurate wake-up of the target UE and reduce the false alarm rate caused by waking up non-target UEs.

[0127] like Figure 4 The diagram illustrates a network topology based on PEI paging packets. A network device can add a PEI packet message before each of the four power points (PFs) in a DRX. The PEI contains the packet number of the target UE that the network device actually needs to wake up, representing all UEs associated with all points (POs) under the corresponding PF. For ease of description, the PEI-based paging packet number (SubGroup, SG) is denoted as the PEI packet number. It should be noted that the PEI packet number for the same UE may be the same or different under different PFs. The PEI packet numbers for different UEs may also be the same or different. Furthermore, all UEs associated with the same PO are divided into multiple groups, with the number of UEs in each group being less than the total number of UEs associated with that PO.

[0128] like Figure 4 As shown, PF1 contains PO0 and PO1. PO0 is associated with 9 UEs: ue1, ue2, ue3, ue4, ue5, ue6, ue7, ue8, and ue9. PO1 is associated with 9 UEs: ue10, ue11, ue12, ue13, ue14, ue15, ue16, ue17, and ue18.

[0129] Similarly, PF2 also has PO0 and PO1. PO0 is associated with 9 UEs: ue11, ue22, ue33, ue44, ue55, ue66, ue77, ue88, and ue99. PO1 is associated with 9 UEs: ue23, ue24, ue25, ue26, ue27, ue28, ue29, ue30, and ue31.

[0130] like Figure 4 As shown, the nine UEs associated with PO0 under PF1 are divided into three groups: SG1{ue1, ue2, ue3}, SG2{ue4, ue5, ue6}, and SGN{ue7, ue8, ue9}. Correspondingly, the nine UEs associated with PO1 under PF1 are also divided into three groups: SG1{ue10, ue11, ue12}, SG2{ue113, ue14, ue15}, and SGN{ue16, ue17, ue18}.

[0131] Similarly, the nine UEs associated with PO0 under PF2 are also divided into three groups: SG1{ue11, ue22, ue33}, SG2{ue44, ue55, ue66}, and SGN{ue77, ue88, ue99}. Correspondingly, the nine UEs associated with PO1 under PF2 are also divided into three groups: SG1{ue23, ue24, ue25}, SG2{ue26, ue27, ue28}, and SGN{ue29, ue30, ue31}.

[0132] The network device adds a packet message (PEI) before each PF. The PEI contains the PEI packet number of all UEs associated with all POs under the corresponding PF for the target UE that the network device actually needs to wake up. Each UE listens for the PEI at the data offset position before the corresponding PF to obtain the PEI packet number of the target UE to be woken up. If the UE determines that the PEI packet number corresponding to the target UE indicated by the PEI is the same as its own PEI packet number, or if the UE determines that the PEI packet number corresponding to the target UE indicated by the PEI is the same as its own PEI packet number, then it listens for the PO under the corresponding PF.

[0133] like Figure 4 As shown, the target UE that the network device actually wants to wake up is ue1, and the first group number of ue1 is SG1. PEI sets the number of bits occupied by the PEI group number to 00000001 to indicate that all UEs with PEI group number SG1 should be woken up. Multiple UEs associated with PO0 and PO1 under PF1 listen to PEI to determine that the first group number of the target UE is SG1. Group SG1 includes ue1, ue2, and ue3. ue1, ue2, and ue3 listen to PO0. UEs in other PEI groups do not need to listen to PO, and therefore do not need to perform subsequent operations such as receiving and decoding paging messages.

[0134] The PEI-based paging packet method actually wakes up one UE (ue1), and also wakes up ue1, ue2, and ue3. Only non-target UEs within the same PEI packet are woken up; multiple non-target UEs in SG2 and SG3 groups of PO0, which are not in the same PEI packet, are not woken up. Compared to a scheme that directly wakes up multiple associated UEs listening to PO without paging packets, this reduces the false alarm rate.

[0135] While PEI-based paging packet methods reduce the false alarm rate of non-target UEs being woken up to some extent, a certain number of non-target UEs still wake up. Therefore, network devices can also add a paging packet method based on Low Power Wake-Up Signal (LP-WUS). The UE can enter Ultra-Deep Sleep Mode, and in this mode, it stops listening to the PO (Position Target). The network device can then wake the UE via LP-WUS to listen to the PO. PEI-based paging packet methods are more suitable for some small, power-sensitive, static, mobility-restricted, and slow-moving UEs.

[0136] like Figure 5 The diagram shown illustrates a device and network topology based on LP-WUS paging packets. Figure 5 As shown in (1), the UE includes a low-power wake-up receiver (LR) and a main radio receiver (MR). The LR has lower power consumption and can operate continuously, listening to LP-WUS. In contrast, the MR has higher power consumption.

[0137] When the UE meets the conditions for listening to LP-WUS, it enters a very deep sleep state. For example... Figure 5 As shown in (2), the conditions for a UE to meet the LP-WUS listening requirements may include: the UE being in RRC_IDLE or RRC_Inactive and being within the coverage area of ​​the LP-WUS wake-up signal sent by the network device. In deep sleep mode, the UE can choose to enable LR and listen for the LP-WUS wake-up signal through LR.

[0138] The UE can also choose to stop listening to the POP and control the MR to enter a low-power state to save power. The MR is in a low-power state, such as being off, in hibernation, or in sleep mode. When the main radio receiver is in a low-power state, it will not listen for paging messages (i.e., listen for the POP). Waking up the main radio receiver can be understood as bringing it from a low-power state into a working state, which can be understood as the traditional state of listening for paging messages.

[0139] If a network device needs to wake up the UE's MR to listen to the PO, it can send an LP-WUS signal, which indicates that the UE needs to be woken up. The UE's LR hears the LP-WUS signal and wakes up the MR to listen to the PO.

[0140] In practical implementation, network devices can wake up UEs based on LP-WUS by indicating the packet number of the UE to be woken up. For ease of description, the paging packet number based on LP-WUS will be referred to as the LP-WUS packet number. For example... Figure 5 As shown in (3), the network device can send LP-WUS before the PF. LP-WUS indicates the LP-WUS packet number of the target UE that is actually woken up. The UE's LR listens to the LP-WUS before the corresponding PF, and checks whether the LP-WUS packet number of the target UE indicated by LP-WUS includes its own LP-WUS packet number. After determining that it includes its own LP-WUS packet number, it can wake up the MR to listen to the PO.

[0141] Continue as Figure 5 As shown in (3), assume that the target UE that the network device actually wants to wake up is ue2, and the LP-WUS group number of ue2 is SG1. The number of bits of the LP-WUS group number included in LP-WUS is set to 00000001, indicating that the UE in the LP-WUS group number SG1 is to be woken up. Multiple UEs associated with PO0 and PO1 under PF1 listen to LP-WUS and determine that the second group number of the target UE is SG1. The SG1 group includes ue1, ue2 and ue3. ue1, ue2 and ue3 wake up their own MR to listen to PO0. Other UEs do not need to listen to PO0, and therefore do not need to perform subsequent operations such as receiving paging messages and decoding.

[0142] Based on the LP-WUS paging packet method, the network device actually wakes up one UE (UE2). Within the same LP-WUS packet, only two additional non-target UEs are woken up; multiple non-target UEs associated with PO0 in SG2 and SG3 groups are not woken up. Compared to a scheme that directly wakes up multiple associated UEs to listen to PO without paging packets, this reduces the false alarm rate.

[0143] To further reduce the false alarm rate, network devices can add a joint paging packet method based on LP-WUS and PEI. The network device sends LP-WUS paging packets and PEI paging packets to multiple UEs separately. Each UE corresponds to two packet numbers: an LP-WUS packet number and a PEI packet number. The first and second packet numbers for the same UE may differ. By using these two packet numbers to indicate the target UE, the network device achieves relatively higher accuracy and a lower false alarm rate.

[0144] The network device sends LP-WUS and PEI before the PF. LP-WUS indicates the LP-WUS packet number corresponding to the target UE, and PEI indicates the PEI packet number corresponding to the target UE. The UE listens to LP-WUS and PEI, and determines whether it needs to listen to PO by combining the LP-WUS packet number indicated by LP-WUS and the PEI packet number indicated by PEI. For example, the UE determines whether it needs to listen to PO by checking whether the intersection of all UEs corresponding to the PEI packet number and all UEs corresponding to the PEI packet number includes itself.

[0145] In specific implementation, such as Figure 6 As shown in (1), before each PF / PO, the network device can send LP-WUS first, and then send PEI. The UE can first listen for LP-WUS in the monitor window where the LP-WUS listening time is located, and then listen for PEI at the PEI listening time. There is a certain time interval between the LP-WUS listening time and the PEI listening time. During this time interval, the UE's LR can wake up its own MR. The time period from when the LR starts waking up the MR until the MR is woken up is set as the MR wake-up time or thread start time (MR ramp-up time). After the MR is woken up, it listens for the downlink synchronization signal Sync and can then start listening for PEI.

[0146] The LP-WUS listening time and PEI listening time can be configured by the network device. Therefore, when the LR detects LP-WUS and wakes up the MR, the PEI listening time may not have arrived yet, or it may have already passed. The duration of the MR wake-up period varies for different UEs. Figure 6 As shown in (1), the wake-up period of UE1's MR is relatively long, while the wake-up period of UE2's MR is relatively short. At the same time, UE1's LR starts to wake up the corresponding MR, and UE2's LR also starts to wake up the corresponding MR. It can be seen that when UE2's MR is woken up and receives the downlink synchronization signal, the PEI's listening time has not yet arrived, and UE2's MR can listen to the PEI when the PEI's listening time arrives. When UE1's MR is woken up and receives the downlink synchronization signal, the PEI's listening time has already passed, and UE1's MR can no longer listen to the PEI, but can directly listen to the corresponding PO.

[0147] The UE's MR can determine whether it can listen to PEI after being woken up by calculating relevant durations. The listening time of PO is denoted as t0, the listening time of PEI as t1, and the listening time of LP-WUS as t2. The MR's wake-up period is denoted as T1, the MR's downlink synchronization period as T2, and offset1 = t0 - t2, offset2 = t0 - t1. If offset1 - offset2 ≥ T1 + T2, the MR can listen to PEI; otherwise, the MR cannot listen to PEI. The communication method provided in this embodiment allows the MR to listen to PEI during PEI listening opportunities and obtain the PEI packet number of the target EU indicated by the PEI.

[0148] like Figure 6 As shown in (2), the PO is associated with multiple UEs: ue1, ue2, ue3, ue4, ue5, ue6, ue7, ue8, and ue9. The LP-WUS group includes: SG1{ue1, ue2, ue3}, SG2{ue4, ue5, ue6}, and SG3{ue7, ue8, ue9}. The PEI group includes: SG1{ue1, ue4, ue7}, SG2{ue2, ue5, ue8}, and SG3{ue3, ue6, ue9}.

[0149] The target UE that the network device actually needs to wake up is ue2. The LP-WUS packet number corresponding to ue2 is SG1, and the PEI packet number corresponding to ue2 is SG2. The LP-WUS-indicated target UE corresponds to SG1, and the PEI-indicated target UE corresponds to SG2. In LP-WUS-based packets, SG1 includes ue2, ue1, and ue3. In PEI-based packets, SG2 includes ue2, ue5, and ue8. For example... Figure 6 As shown in (3), the intersection of all UEs included in LP-WUS group number SG1 and all UEs included in PEI group number SG2 is denoted as the target UE that the network device needs to wake up.

[0150] By obtaining the intersection of all UEs included in the LP-WUS packets and all UEs included in the PEI packets, the UE can more accurately determine the target device that the network device needs to wake up. For example... Figure 6As shown in (4) above, this is another example of joint paging grouping. ue1, ue2...ue8 are grouped using LP-WUS to obtain Group1{ue1, ue2}, Group2{ue3, ue4}, Group3{ue5, ue6}, and Group4{ue7, ue8}. Correspondingly, ue1, ue2...ue8 are then grouped using PEI to obtain Group1{ue1, ue2, ue3, ue4} and Group2{ue5, ue6, ue7, ue8}. It can be seen that when LP-WUS and PEI groups are orthogonal, the closer the UE determined by the intersection of LP-WUS and PEI groups is to the target UE, the lower the false alarm rate.

[0151] Continue as Figure 6 In (2), the nine UEs associated with PO first listen to LP-WUS through LR. When they detect that the second group number indicated by LP-WUS is SG1, ue1, ue2 and ue3 wake up their own MR to continue listening to PEI. The UEs in SG2 and SG3 do not need to wake up their own MR to listen to PEI and PO.

[0152] If ue1, ue2, and ue3 are listening to PEI via MR (Modified Receiver), and the PEI group number indicated by PEI is SG2, and group SG2 includes ue2 but excludes ue1 and ue3, then ue2 needs to listen to PO (Position Item), while ue1 and ue3 do not. In this case, ue1 and ue3 can continue to enter a deep sleep state, disable MR, and continue listening to LP-WUS via LR (Redirect Receiver). In other cases, ue1 and ue3 can also keep MR enabled without restriction.

[0153] For ue5 and ue8 in the SG2 group specified by PEI, ue5 does not detect the corresponding SG2 through LR listening to LP-WUS, so there is no need to wake up MR to listen to PEI and PO. Similarly, ue8 does not detect the corresponding SG3 through LR listening to LP-WUS, so there is no need to wake up MR to listen to PEI and PO.

[0154] Network devices using a combined paging packet method based on LP-WUS and PEI can more accurately indicate the target UE that needs to be woken up, further reducing the false alarm rate. Before each PF, the network device can send a combined paging packet method of LP-WUS followed by PEI, which can reduce both the false alarm rate of non-target UEs and the power consumption of waking up MRs from non-target UEs.

[0155] Network devices use LP-WUS to indicate the LP-WUS packet number corresponding to the target UE and PEI to indicate the PEI packet number corresponding to the target UE. When network devices execute both types of paging packets for multiple UEs, it's possible that two or more UEs may have the same first category number and the same second category number. In this case, if the network device actually needs to wake up one of the UEs, using joint paging packets might wake up the other UEs among the two or more UEs, resulting in a certain false alarm rate.

[0156] Network devices can use a combined paging packet method to wake up target UEs. They can adjust the packet scheme based on LP-WUS paging packets and PEI paging packets to minimize the situation where any two UEs have the same PEI packet number and LP-WUS packet number. In other words, they can make the UEs woken up by the network device based on LP-WUS indication and the UEs woken up based on PEI indication as different as possible to further reduce the false alarm rate.

[0157] Table 1 below shows the LP-WUS-based packet scheme for multiple UEs, and Table 2 shows the PEI-based packet scheme for multiple UEs.

[0158] The target UE that the network device needs to wake up is ue10, whose LP-WUS packet number based on LP-WUS is L0. L0 also includes: ue5, ue15, ue20, ue25, ue30, ue35, and ue40. The PEI packet number based on PEI for ue10 is P2. P2 also includes: ue8, ue9, ue11, ue28, ue29, ue30, and ue31.

[0159] It is evident that the UEs woke up by the network device include not only the target UE (ue10) but also non-target UEs (ue30), resulting in a relatively low false alarm rate.

[0164] Network devices can implement paging packets for multiple UEs associated with a PO based on the PEI in several ways. For example, the core network can directly provide the PEI packet number for each UE. Alternatively, the corresponding PEI packet number can be calculated using each UE's user identifier and a packet formula.

[0165] Before introducing how the UE calculates the PEI and LP-WUS block numbers, let's first introduce the specific implementation scheme for the UE to determine its own PO. The UE can calculate the corresponding PO using the PO calculation formula.

[0166] The UE can first calculate Ns, which is the number of POs configured under one PF, using the formula (SFN + PF_offset) mod T = (T div N) * (UE_ID mod N). Here, SFN represents the system frame number to be calculated, T represents the paging period, N represents the number of PFs within one DRX period, PF_offset represents the PF offset, and T div N represents the quotient and remainder of T divided by N. UE_ID can be 5G-S-TMSI mod 1024.

[0167] The UE then calculates the PO using the formula: i_s = floor(UE_ID / N) mod Ns; where Ns represents the number of POs under one PF.

[0168] In one specific implementation, the formula for calculating the PEI subgroup ID based on the UE's user identifier may include: PEISubgroupID = (floor(UE_ID / (N*Ns))modsubgroupsNumForUE_ID) +

[0169] (subgroupsNumPerPO–subgroupsNumForUE_ID).

[0170] Wherein, PEISubgroup ID represents the UE's PEI group number, UE_ID is the UE's user identifier, N represents the number of PFs within a DRX period, and Ns represents the number of POs under a PF. subgroupsNumPerPO represents the total number of PO groups, which is the total number of PEI groups corresponding to all UEs associated with each PO. subgroupsNumForUE_ID represents the number of PO cell groups, which is the number of groups allocated by the cell in the PEI groups corresponding to all UEs associated with each PO. Normally, when performing PEI grouping on all UEs associated with a PO, the total number of PEI groups is determined. Of the total number of PEI groups, a portion is allocated by the core network and a portion is allocated by the cell. In the joint paging grouping scheme provided in this embodiment, the core network no longer occupies a portion of the PEI groups, that is, the number of groups allocated by the cell can be the total number of PO cell groups. Therefore, the difference between the total number of PO cell groups and the number of groups allocated by the cell may be 0.

[0171] In addition, the PEI group number calculation formula involves two functions: the floor function `floor(x)` and the modulo function `x mod y`. The floor function `floor(x)` takes the largest integer not greater than x. The modulo function `x mod y` takes the remainder when x is divided by y, where y is the modulus.

[0172] In practical implementation, the user identifier UE_ID used by the UE to calculate the PEI packet number can be obtained based on the UE's 5G System-Temporary Mobile Subscriber Identity (5G-S-TMSI). The 5G-S-TMSI consists of 48 bits of characters, i.e., <5G-S-TMSI> =<AMF Set ID> <amfpointer><5G-TMSI>. Among them, AMF SET ID is 10 bits, which includes the first 10 bits of 5G-S-TMSI, AMFPointer includes 6 bits of 5G-S-TMSI, and 5G-TMSI includes the last 32 bits of 5G-S-TMSI.

[0173] In one specific example, UE_ID can be obtained by taking the modulo of 5G-S-TMSI. For example: UE_ID = 5G-S-TMSI mod X, where X is a multiple of 1024. Where X is 32768 if the UE is in Extended Discontinuous Reception (eDRX) mode, otherwise X is 8192.

[0174] Network devices can implement paging packets for multiple UEs associated with a PO based on LP-WUS in several ways. For example, the core network can directly provide the LP-WUS packet number for each UE. Alternatively, the LP-WUS packet number can be calculated using each UE's user identifier and the PEI packet formula. For clarity, the formula for calculating the LP-WUS packet number based on the UE's user identifier will be referred to as the LP-WUS calculation formula.

[0175] In one specific implementation, the LP-WUS packet number calculation formula for the UE to calculate the packet number based on the UE's user identifier may include:

[0176] LP-WUSSubgroupID=floor(UE_ID / (N*Ns)modsubgroupsNumForLP-WUSUE_ID+(subgroupsNumPerPOForLP-WUS–subgroupsNumForLP-WUSUE_ID).

[0177] Wherein, LP-WUSSubgroupID represents the UE's LP-WUS packet number, UE_ID is the UE's user identifier, N represents the number of PFs within a DRX period, and Ns represents the number of POs under a PF. represents the number of LP-WUS packets based on the user identifier, and subgroupsNumPerPOForLP-WUS represents the total number of packets for each PO. subgroupsNumPerPOForLP-WUS represents the total number of LP-WUS packets corresponding to all UEs associated with a PO. subgroupsNumForLP-WUSUE_ID represents the number of PO cell packets, which is the number of packets allocated by the cell in the LP-WUS packets corresponding to all UEs associated with each PO. Normally, when subgroupsNumPerPOForLP-WUS is performed on all UEs associated with a PO, the total number of LP-WUS packets is determined. Of the total number of LP-WUS packets, a portion is allocated by the core network and a portion by the cell. In the joint paging packet scheme provided in this embodiment, the core network no longer occupies a portion of the LP-WUS packets; that is, the number of packets allocated by the cell can be the total number of PO cell packets. Therefore, the difference between the total number of packets in the PO cell and the number of packets allocated by the cell may be 0. Furthermore, the second calculation formula also involves the floor function floor(x) and the modulo function x mod y, which will not be elaborated further.

[0178] In the LP-WUS group number calculation formula, `subgroupsNumForLP-WUSUEID` may be the same as `subgroupsNumForUEID` in the first calculation formula, and `subgroupsNumPerPOForLP-WUS` in the second calculation formula may be the same as `subgroupsNumPerPO` in the first calculation formula. Furthermore, the functions involved in the first and second calculation formulas are also the same.

[0179] To ensure that the PEI group number SubgroupID of the UE obtained based on the PEI group number calculation formula is as different as possible from the LP-WUS group number LP-WUSSubgroupID of the UE obtained based on the LP-WUS group number calculation formula, the floor(UE_ID / (N*Ns)) in the first calculation formula and the floor(UE_ID / (N*Ns)) in the second calculation formula can be made as different as possible.

[0180] Based on this, the inventors creatively proposed that by modifying some parameters in the LP-WUS group number calculation formula, the group numbers obtained by different UEs based on the two paging grouping methods can be made as different as possible.

[0181] like Figure 7 As shown in (1) above, this is a flowchart illustrating a communication method provided in this embodiment. In this embodiment, the first terminal can be the aforementioned UE, and the network device can be the aforementioned base station, core network, etc. The base station can be a NodeB, eNB, gNB, etc. The UE includes a main radio frequency receiver (MR) and a low-power wake-up receiver (LR). Specifically, the provided communication method mainly includes the following steps:

[0182] S71: The network device sends a first wake-up signal; wherein, the first wake-up signal is a low-power wake-up signal, the first wake-up signal carries first wake-up information, and the first wake-up information indicates the group number of the first group of the target terminal that needs to be woken up.

[0183] S72: The UE listens for the first wake-up information through the low-power wake-up receiver.

[0184] S73: The network device sends a second wake-up signal; wherein the second wake-up signal carries second wake-up information, the second wake-up information indicating the group number of the second group of the target terminal that needs to be woken up.

[0185] S74: If the group number of the first group includes the first group number of the first terminal, the UE listens for the second wake-up information through the main radio frequency receiver.

[0186] When a UE is in RRC_IDLE or RRC_Inactive, it listens for wake-up messages from the network device to determine if it is the target device that the network device needs to wake up. The network device sends paging packets to multiple UEs associated with the PO, using a combined paging packet method that combines the first paging packet and the second paging packet. The first paging packet can be the LP-WUS packet method, and the second paging packet can be the PEI packet method.

[0187] The network device uses a combined packet method to send paging packets to multiple UEs associated with the PO. The LP-WUS packet method can be used to determine the first packet for each UE, and the PEI packet method can be used to determine the second packet for each UE. Each of the multiple UEs associated with the PO exists in its corresponding first and second packets.

[0188] It should be noted that performing a first paging packet on multiple UEs associated with a PO results in multiple first packets, each of which includes multiple UEs. Correspondingly, performing a second paging packet on multiple UEs associated with a PO results in multiple second packets, each of which also includes multiple UEs.

[0189] The first group to which the UE belongs may include the UE and at least one third device. The first group to which the UE and at least one third device belong is the same, while the second group to which the UE and at least one third device belong is usually not exactly the same.

[0190] For ease of description, the group number corresponding to the first group where the UE is located is denoted as the first group number, and the group number corresponding to the second group where the UE is located is denoted as the second group number.

[0191] The target UE is also one of multiple UEs, and the target UE also exists in the corresponding first group and second group. For ease of distinction and description, the group number corresponding to the first group of the target UE is recorded as the group number of the first group of the target terminal, and the group number corresponding to the second group of the target UE is recorded as the group number of the second group of the target terminal.

[0192] The network device needs to wake up the target UE by sending a first wake-up signal and a second wake-up signal. Both the first and second wake-up signals are Radio Resource Control (RRC) signaling sent by the second device. The first wake-up signal is a low-power wake-up signal carrying first wake-up information, which indicates the group number of the first group to which the target UE belongs. The second wake-up signal carries second wake-up information, which indicates the group number of the second group to which the target UE belongs. Specifically, the first wake-up information can be a Paging Early Start Indication (PEI), and the second wake-up information can be a Low-Power Wake-up Signal (LP-WUS).

[0193] The UE can listen for the first wake-up signal via LR and the second wake-up signal via MR.

[0194] S75: If the group number of the second group includes the second group number of the first terminal, the UE listens for paging messages.

[0195] The UE listens to the first and second wake-up signals to obtain the first and second packet numbers of the target UE. The UE can also obtain its own first and second packet numbers. To determine whether it is a target UE that the network device needs to wake up, the UE can detect whether the first and second packets of the target UE are the same as its own.

[0196] In some cases, the number of target UEs woken up by the network device may be one or more. The first wake-up information indicating the first packet number of the target UE may also be one or more, and the second wake-up information indicating the second packet number may also be one or more. If the first terminal is a UE, then both the first packet number and the second packet number are the same packet number. Based on this, to determine whether it is a target UE that the network device needs to wake up, the UE can also detect whether the first packet number of the target UE includes the first packet number, and whether the second packet number of the target UE includes the second packet number.

[0197] The UE detects the first group number of the target device, which includes the first group number of the first terminal, and the second group of the target device includes the second group of the first terminal. The UE can directly listen to the PO or listen to the paging message, that is, the UE listens to the paging message in the corresponding PO.

[0198] Alternatively, the UE can first determine that it is the target device that the network device needs to wake up, and then listen to the PO or listen to the paging message.

[0199] In other cases, if the UE detects that the first packet containing the target device does not include the first packet containing the first terminal, or that the second packet containing the target device does not include the second packet containing the first terminal, the UE may choose not to listen to the PO, or in other words, not to listen to the paging message. This reduces the power consumption caused by the UE listening to and decoding the paging message, thus lowering the false alarm rate.

[0200] To ensure that the group numbers obtained from LP-WUS grouping are different from those obtained from PEI grouping, different parameters or calculation formulas are used to calculate the corresponding group numbers.

[0201] like Figure 7 As shown in (2), the first packet number may include: a first packet baseline number and a first packet offset; the first packet baseline number is obtained based on the first identifier of the first terminal. The second packet number includes: a second packet baseline number and a second packet offset; wherein, the second packet baseline number is obtained based on the second identifier of the first terminal. Wherein, the first packet baseline number is the actual variable for calculating the first packet number, and the first packet baseline number is associated with the identifier of each UE, and the first packet baseline number of different UEs may be different. The first packet offset indicates the packet number offset caused by the number of LP-WUS packets allocated by the core network during the LP-WUS paging packet process. Correspondingly, the second baseline number is the actual variable for calculating the second packet number, and the second packet baseline number is also associated with the identifier of each UE, and the second packet baseline number of different UEs may be different. The second packet offset indicates the packet number offset caused by the number of PEI packets allocated by the core network during the PEI paging packet process.

[0202] If the UE's first identifier and second identifier are different, the first packet baseline number obtained based on the first identifier and the second packet baseline number obtained based on the second identifier may also be different. If the first packet baseline number and the second packet baseline number are different, but the first packet offset and the second packet offset are the same, then the first packet number and the second packet number will be different.

[0203] In a specific example, the second group number PEISubgroupID = (floor(UE_ID2 / (N*Ns))modsubgroupsNumForUE_ID2) +

[0204] (subgroupsNumPerPO–subgroupsNumForUE_ID2). Where the second group baseline number is floor(UE_ID / (N*Ns))modsubgroupsNumForUE_ID2, the second group offset is subgroupsNumPerPO–subgroupsNumForUE_ID2, and the second identifier is floor(UE_ID2 / (N*Ns). Here, UE_ID2 is the UE's user identifier or identification code, N represents the number of PFs within a DRX period, and Ns represents the number of POs under a PF. subgroupsNumPerPO represents the total number of PO groups, corresponding to all UEs associated with each PO. Total number of PEI packets. `subgroupsNumForUE_ID2` represents the number of PO cell packets, specifically the number of packets allocated by the cell to all PEI packets corresponding to all UEs associated with each PO. Normally, when performing PEI packetization on all UEs associated with a PO, the total number of PEI packets is fixed. Of this total, a portion is allocated by the core network and a portion by the cell. In the joint paging packet scheme provided in this embodiment, the core network no longer occupies a portion of the PEI packets; that is, the number of packets allocated by the cell can be the total number of PO cell packets. Therefore, the difference between the total number of PO cell packets and the number of packets allocated by the cell may be 0.

[0205] In addition, the PEI group number calculation formula involves two functions: the floor function `floor(x)` and the modulo function `x mod y`. The floor function `floor(x)` takes the largest integer not greater than x. The modulo function `x mod y` takes the remainder when x is divided by y, where y is the modulus.

[0206] In practical implementation, the user identifier UE_ID used by the UE to calculate the PEI packet number can be obtained based on the UE's 5G System-Temporary Mobile Subscriber Identity (5G-S-TMSI). The 5G-S-TMSI consists of 48 bits of characters, i.e., <5G-S-TMSI> =<AMF Set ID> <amfpointer><5G-TMSI>. Among them, AMF SET ID is 10 bits, which includes the first 10 bits of 5G-S-TMSI, AMFPointer includes 6 bits of 5G-S-TMSI, and 5G-TMSI includes the last 32 bits of 5G-S-TMSI.

[0207] In one specific example, UE_ID can be obtained by taking the modulo of 5G-S-TMSI. For example: UE_ID = 5G-S-TMSI mod X, where X is a multiple of 1024. Where X is 32768 if the UE is in Extended Discontinuous Reception (eDRX) mode, otherwise X is 8192.

[0208] Based on the above implementation method, the calculation formula for the first group number can be similar to that for the second group number. However, based on the difference in the second identifier, a first group number different from the second group number can be obtained. For example, LP-WUSSubgroupID = floor(UE_ID1 / (N*Ns)modsubgroupsNumForLP-WUSUE_ID1+(subgroupsNumPerPOForLP-WUS–subgroupsNumForLP-WUSUE_ID1).

[0209] Wherein, the first group baseline number is floor(UE_ID1 / (N*Ns)modsubgroupsNumForLP-WUSUE_ID1), the first identifier can be floor(UE_ID1 / (N*Ns), and the first group offset can be (subgroupsNumPerPOForLP-WUS–subgroupsNumForLP-WUSUE_ID1). UE_ID1 is the UE's user identifier or identification code; UE_ID1 and UE_ID2 may be the same or different. N represents the number of PFs within one DRX cycle, and Ns represents the number of POs under one PF. This indicates based on... The number of LP-WUS packets for the user identifier, and `subgroupsNumPerPOForLP-WUS` represent the total number of packets for each PO. `subgroupsNumPerPOForLP-WUS` represents the total number of LP-WUS packets corresponding to all UEs associated with the PO. `subgroupsNumForLP-WUSUE_ID` represents the number of PO cell packets, which is the number of packets allocated by the cell in the LP-WUS packets corresponding to all UEs associated with each PO. The difference between the total number of PO cell packets and the number of packets allocated by the cell may be 0. Furthermore, the second calculation formula also involves the floor function `floor(x)` and the modulo function `x mod y`, which will not be elaborated further.

[0210] To ensure that the UE's PEI subgroup ID, calculated using the PEI subgroup ID formula, is as different as possible from the UE's LP-WUS subgroup ID, calculated using the LP-WUS subgroup ID formula, the floor(UE_ID / (N*Ns)) in the first calculation formula and the floor(UE_ID / (N*Ns)) in the second calculation formula can be made as different as possible. The PEI subgroup ID calculation formula may be fixed; however, the LP-WUS subgroup ID calculation formula can be adjusted to ensure that the first and second subgroup IDs are different for each UE.

[0211] In one specific implementation, the first packet offset is equal to the first difference between the total number of first PO packets and the number of first PO cell packets. The total number of first PO packets is the total number of LP-WUS packets corresponding to all UEs associated with each PO, and the number of first PO cell packets is the number of packets allocated by the cell in the LP-WUS packets corresponding to all UEs associated with each PO.

[0212] The second packet offset is equal to the second difference between the total number of second PO packets and the number of second PO cell packets. The total number of second PO packets is the total number of PEI packets corresponding to all UEs associated with each PO, and the number of second PO cell packets is the number of packets allocated by the cell among the PEI packets corresponding to all UEs associated with each PO. The first difference equals the second difference.

[0213] Specifically, when the cell performs paging packets based on the UE_ID, the core network allocates 0 packets. The total number of packets for the first PO is equal to the number of packets for the first PO cell, and the first difference is 0.

[0214] The total number of the second PO group is equal to the number of the second PO cell group, and the second difference is equal to 0.

[0215] Based on this, the first group baseline number is obtained using the first modulo function based on the first identifier. The first modulo function is: first identifier mod first PO cell group number.

[0216] The second group baseline number is obtained based on the second identifier using the second modulo function, which is: second identifier modulo second PO cell group number.

[0217] Based on this, in order to make the first group baseline number obtained by the UE using the first modulo function based on the first identifier different from the second group baseline number obtained by the second modulo function based on the second identifier, the first identifier and the second identifier can be made different.

[0218] The following will explain, through several specific implementation methods, the implementation schemes involving the different first and second identifiers in the communication method provided in this embodiment.

[0219] Implementation Method 1

[0220] The UE determines the first identifier based on UE_ID1 and the second identifier based on UE_ID2. Different first and second identifiers can be obtained through different UE_ID1 and UE_ID2.

[0221] UE_ID2 is obtained by taking the modulus of the UE's 5G-S-TMSI with X as the modulus. UE_ID1 can be made different from UE_ID2 by adjusting different bits of the UE's 5G-S-TMSI.

[0222] In a specific example, the first identifier is floor(UE_ID1 / (N*Ns)), and the second identifier is floor(UE_ID2 / (N*Ns)).

[0223] Where floor(*) is the floor function, N is the number of paging frames (PF) in one DRX period, and Ns is the number of paging times (PO) configured in one paging frame.

[0224] UE_ID1 is the third identifier of the first terminal. The third identifier includes any one of the following: the 5G-S-TMSI of the first terminal, the 5G-TMSI of the first terminal, a portion of the 5G-S-TMSI of the first terminal, or the terminal identifier configured by the network side; the terminal identifier configured by the network side is different from UE_ID2.

[0225] Specifically, the 5G-S-TMSI of the first terminal includes the first 9 bits (ng-5G-S-TMSI-Part2) and the leftmost 9 bits of the 5G-S-TMSI. Alternatively, the 5G-S-TMSI of the first terminal includes the last 39 bits (ng-5G-S-TMSI-Part1) and the rightmost 39 bits of the 5G-S-TMSI.

[0226] UE_ID2 is equal to the 5G-S-TMSI of the first terminal mod X, where X is a multiple of 1024. Specifically, if the UE is in Extended Discontinuous Reception (eDRX) mode, X is 32768; otherwise, X is 8192.

[0227] In other cases, the third identifier may also include other identifiers of the first terminal. For example, the third identifier may be obtained by hashing the commonly used UE identity = 5G-S-TMSI mod X. The third identifier may be a hashed user identifier configured by the network device.

[0228] Alternatively, when the UE is in the inactive state (INACTIVE), it can obtain a third identifier using the long value or I-RNTI-Value or the short value of the temporary mobile subscriber identifier (TMI) assigned by the network device, without limitation.

[0229] like Figure 8 The diagram shown illustrates the interaction between the UE and the base station on the network side in the scenario of Example 1. It mainly includes the following steps:

[0230] S81: The base station sends a system information block indicating the combination of LP-WUS paging packets and PEI paging packets.

[0231] The system sends a System Information Block (SIB) instructing to combine LP-WUS and PEI (LP-WUS and PEI coexist) and configure the wake-up parameters of LP-WUS and PEI respectively (SIB LP-WUSconfig (LP-WUS and PEI coexist) PEI config).

[0232] S82: The UE determines the number of packets for joint paging based on the UE_ID.

[0233] The UE determines the number of coexisting paging packets based on the LP-WUS wake-up parameters and PEI wake-up parameters sent by the base station, not just the number of LP-WUS packets based on the UE_ID. This number of coexisting paging packets can be different numbers of LP-WUS packets and PEI packets, or it can be the same number of LP-WUS packets and PEI packets; there are no restrictions.

[0234] S83: UE power-on registration, receiving the UE's device identifier.

[0235] After the UE powers on, it registers an RRC connection with the base station and receives the EU's device identifier returned by the base station. The EU's device identifier received here can be a 5G-S-TMSI or a hashed UE identity configured by the network device.

[0236] In one scenario, the device identifier (UE_ID1) sent by the base station for the EU is obtained based on 5G-S-TMSI. For example, UE_ID1 can be any of 5G-S-TMSImodY, 5G-S-TMSI, 5G-TMSI, ng-5G-S-TMSI-Part1, g-5G-S-TMSI-Part2, or 5G-TMSI.

[0237] In another scenario, the device identifier of the EU sent by the base station is a hashed identifier configured for the network device. For example, UE_ID1 is a hashed UE identity configured for the network device, and the hashed UE identity is not equal to 5G-S-TMSImodX.

[0238] In another scenario, when the UE is in the INACTIVE state of RRC, the device identifier of the EU sent by the base station can also be either I-RNTI-Value or ShortI-RNTI-Value.

[0239] It can be the third identifier mentioned in this embodiment, that is, the user identifier obtained by removing some bits of the UE's 5G-S-TMSI, or it can be the user identifier obtained by further hash mapping the obtained 5G-S-TMSI bits using a hash function (hash UE identity), without limitation.

[0240] S84: The base station releases the RRC connection.

[0241] The base station receives the RRC connection registered by the UE after power-on and releases the RRC connection signaling. The UE enters RRC_IDLE or RRC_Inactive, and the UE meets the LP-WUS condition. In this case, the UE's LR listens for LP-WUS, MR is turned off, and it can enter a very deep sleep state.

[0242] S85: The base station sends LP-WUS.

[0243] S86: The UE's LR detects LP-WUS, wakes up the MR, downloads the downlink synchronization signal, and determines when PEI monitoring is possible.

[0244] The base station sends LP-WUS, and the UE's LR listens to LP-WUS. The UE detects that the first packet number of the target UE indicated by LP-WUS includes the first packet number of the first terminal, and the UE wakes up its MR. The MR needs a certain amount of time to be woken up. After the MR is woken up, it determines whether there is still a PEI listening opportunity, that is, whether the PEI listening time has not yet arrived. If it has not arrived, it is determined that there is a PEI listening opportunity, and the MR listens for PEI during the PEI listening time.

[0245] S87: The base station sends PEI.

[0246] S88: UE listens to PEI.

[0247] The base station sends the PEI at the configured PEI listening time according to the configured PEI parameters, and the UE listens for the PEI at the corresponding PEI listening time. The UE then further determines whether the packet number of the second packet of the target UE indicated by the PEI includes the second packet number of the first terminal. If it does, the UE listens for the PO; otherwise, it does not need to listen for the PO.

[0248] Implementation Method 2

[0249] The UE determines the first identifier based on UE_ID1 and the second identifier based on UE_ID2. Different first and second identifiers can be obtained through different UE_ID1 and UE_ID2.

[0250] UE_ID2 is obtained by taking the modulus of the UE's 5G-S-TMSI with X as the modulus. UE_ID1 can be obtained by taking the modulus of the 5G-S-TMSI with Y as the modulus, which is different from X, so that UE_ID1 and UE_ID2 are different.

[0251] In a specific example, the first identifier is floor(UE_ID1 / (N*Ns)), and the second identifier is floor(UE_ID2 / (N*Ns)). Here, floor(*) is a floor function, N is the number of paging frames (PF) in one DRX period, and Ns is the number of paging times (PO) configured in one paging frame.

[0252] UE_ID2 equals the 5G-S-TMSI of the first terminal mod X. UE_ID1 equals the third identifier of the first terminal mod Y. Both X and Y are multiples of 1024, and X is not equal to Y. For example, X is 32768 in the application state of a discontinuous reception cycle and 8192 in other states. Therefore, Y can be any value other than 32768 in the application state of a discontinuous reception cycle, and any value other than 8192 in other states. For example, Y can be 4096, 5120, 6144, 7168, 9216, or 10240.

[0253] The third identifier includes the GS-TMSI of the first terminal. In this case, UE_ID1 = 5G-S-TMSI mod Y. Even if UE_ID1 and UE_ID2 are both modulo the same 5G-S-TMSI, the resulting UE_IDs will be different due to the different modulo values.

[0254] In the scenario of Example 2, the specific process of interaction between the UE and the base station can be found in the foregoing. Figure 8 As shown, no further details will be provided.

[0255] Implementation Method 3

[0256] The UE determines the first identifier based on UE_ID1 and the second identifier based on UE_ID2. Different first and second identifiers can be obtained through different UE_ID1 and UE_ID2.

[0257] UE_ID2 is obtained by taking the modulus of the UE's 5G-S-TMSI with X as the modulus. UE_ID1 can be made different from UE_ID2 by adjusting and extracting different bits of the UE's 5G-S-TMSI and taking the modulus with Y as the modulus, which is different from X.

[0258] In a specific example, the first identifier is floor(UE_ID1 / (N*Ns)), and the second identifier is floor(UE_ID2 / (N*Ns)). Here, floor(*) is a floor function, N is the number of paging frames (PF) in one DRX period, and Ns is the number of paging times (PO) configured in one paging frame.

[0259] UE_ID2 equals the 5G-S-TMSI of the first terminal mod X. UE_ID1 equals the third identifier of the first terminal mod Y. Both X and Y are multiples of 1024, and X is not equal to Y. For example, X is 32768 in the application state of a discontinuous reception cycle and 8192 in other states. Therefore, in the application state of a discontinuous reception cycle, Y can be any value other than 32768, and in other states, Y can be any value other than 8192.

[0260] In another scenario, the third identifier includes any one of the following: the 5G-TMSI of the first terminal, a portion of the 5G-S-TMSI of the first terminal, or a terminal identifier configured on the network side; the terminal identifier configured on the network side is different from UE_ID2. In this case, UE_ID1 = {any one of the 5G-TMSI of the first terminal, a portion of the 5G-S-TMSI of the first terminal, or a terminal identifier configured on the network side} mod Y. Since UE_ID1 and UE_ID2 use different modulo parameters and have different moduli, the resulting UE_ID1 and UE_ID2 are also highly likely to be different.

[0261] In the scenario of Example 3, the specific process of interaction between the UE and the base station can be found in the foregoing. Figure 8 As shown, no further details will be provided.

[0262] Implementation Method 4

[0263] The UE determines the second identifier based on UE_ID2, as well as N and Ns. The UE can also determine the first identifier based on UE_ID1 and a new parameter Nh to obtain different first and second identifiers.

[0264] In a specific example, the first identifier is floor(UE_ID1 / Nh), and the second identifier is floor(UE_ID2 / (N*Ns)). Here, floor(*) is a floor function, N is the number of paging frames (PF) in one DRX period, Ns is the number of paging times (PO) configured in one paging frame, and Nh is a value configured on the network side, which is not equal to N*Ns.

[0265] UE_ID2 is equal to the 5G-S-TMSI mod X of the first terminal, and the second identifier is floor(5G-S-TMSI mod X / (N*Ns)). Since the parameter Nh in the first identifier is different from the parameter N*Ns in the second identifier, UE_ID1 and UE_ID2 can be the same or different.

[0266] In one case, UE_ID1 and UE_ID2 are the same.

[0267] For example, UE_ID1 is equal to the third identifier of the first terminal mod Y, where X and Y are both multiples of 1024, and X equals Y. The third identifier includes the 5G-S-TMSI of the first terminal.

[0268] In this case, the first identifier is floor(5G-S-TMSI modX / Nh), and the second identifier is floor(5G-S-TMSI modX / (N*Ns)).

[0269] In another case, UE_ID1 and UE_ID2 are not the same.

[0270] For example, UE_ID1 is equal to the third identifier of the first terminal. The third identifier includes any one of the 5G-S-TMSI of the first terminal, the 5G-TMSI of the first terminal, a portion of the 5G-S-TMSI of the first terminal, or the terminal identifier configured on the network side; the terminal identifier configured on the network side is different from UE_ID2.

[0271] In this case, the first identifier is floor({any one of the 5G-TMSI of the first terminal, a portion of the 5G-S-TMSI of the first terminal, or the terminal identifier configured on the network side} / Nh), and the second identifier is floor(5G-S-TMSImodX / (N*Ns)).

[0272] For example, UE_ID1 is equal to the third identifier of the first terminal mod Y, where both X and Y are multiples of 1024, and X may or may not be equal to Y. The third identifier includes any one of the following: the 5G-TMSI of the first terminal, a portion of the 5G-S-TMSI of the first terminal, or the terminal identifier configured on the network side; the terminal identifier configured on the network side is different from UE_ID2.

[0273] In this case, the first identifier is floor({any one of the 5G-TMSI of the first terminal, a portion of the 5G-S-TMSI of the first terminal, or the terminal identifier configured on the network side}modY / Nh), and the second identifier is floor(5G-S-TMSImodX / (N*Ns)).

[0274] In the aforementioned scenarios, Nh is a value configured for the network device, and Nh is not equal to N*Ns. For example, Nh can be 1, in which case the first identifier is floor(UE_ID1). In other cases, Nh can also be a random number, without restriction.

[0275] like Figure 9 The diagram shown illustrates the interaction between the UE and the base station on the network side in scenario 4 of Example 4. It mainly includes the following steps:

[0276] S91: The base station sends a system information block configuring LP-WUS and PEI. The system message block carries Nh, which indicates the combination of LP-WUS paging packets and PEI paging packets.

[0277] The system sends a System Information Block (SIB) instructing that LP-WUS and PEI be combined (LP-WUS and PEI coexist), configuring the LP-WUS wake-up parameters and PEI wake-up parameters respectively (SIB LP-WUSconfig (LP-WUS and PEI coexist) PEI config). The SIB carries Nh, a value configured for the network device; Nh is not equal to N*Ns. Nh can be a random number or 1. Besides being used to calculate the UE's first packet number, Nh is also used to indicate the combined packet.

[0278] S92: The UE determines the number of packets for joint paging based on the UE_ID.

[0279] The UE determines the number of coexisting paging packets based on the LP-WUS wake-up parameters and PEI wake-up parameters sent by the base station, not just the number of LP-WUS packets based on the UE_ID. This number of coexisting paging packets can be different numbers of LP-WUS packets and PEI packets, or it can be the same number of LP-WUS packets and PEI packets; there are no restrictions.

[0280] S93: UE enters RRC connection state.

[0281] The UE initiates an RRC connection and enters the connected state RRC_Connectc.

[0282] S94: The base station releases the RRC connection.

[0283] The base station receives the RRC connection registered by the UE after power-on and releases the RRC connection signaling. The UE enters RRC_IDLE or RRC_Inactive, and the UE meets the LP-WUS condition. In this case, the UE's LR listens for LP-WUS, MR is turned off, and it can enter a very deep sleep state.

[0284] S95: The base station sends LP-WUS.

[0285] S96: The UE's LR detects LP-WUS, wakes up the MR, downloads the downlink synchronization signal, and determines when PEI monitoring is possible.

[0286] The base station sends LP-WUS, and the UE's LR listens to LP-WUS. The UE detects that the first packet number of the target UE indicated by LP-WUS includes the first packet number of the first terminal, and the UE wakes up its MR. The MR needs a certain amount of time to be woken up. After the MR is woken up, it determines whether there is still a PEI listening opportunity, that is, whether the PEI listening time has not yet arrived. If it has not arrived, it is determined that there is a PEI listening opportunity, and the MR listens for PEI during the PEI listening time.

[0287] S97: The base station sends PEI.

[0288] S98: UE's MR listening to PEI.

[0289] The base station sends the PEI at the configured PEI listening time according to the configured PEI parameters, and the UE listens for the PEI at the corresponding PEI listening time. The UE then further determines whether the packet number of the second packet of the target UE indicated by the PEI includes the second packet number of the first terminal. If it does, the UE listens for the PO; otherwise, it does not need to listen for the PO.

[0290] In the communication method provided in this embodiment, the UE can receive a first message sent by the network device. The first message can be a message indicating a combined packet. The first message carries Nh, and the combined packet message instructs the first terminal to listen for paging messages based on the packet number of the first packet and the packet number of the second packet.

[0291] In other cases, network devices can also hash N*Ns to obtain Nh, where Nh is not equal to N*Ns, thus making the PEI and LP-WUS packets configured for the same UE different by configuring the hash parameter Nh.

[0292] Example 5

[0293] In this embodiment, the first packet number corresponding to the LP-WUS paging packet and the second packet number corresponding to the PEI packet for the UE can also be directly configured by the network device. The specific scheme for configuring the first and second packet numbers by the network device can be random configuration or configuration based on the schemes involved in the aforementioned embodiments 1-4, without limitation.

[0294] like Figure 10 The diagram shown illustrates the interaction between the UE and the base station on the network side in scenario 4 of Example 4. It mainly includes the following steps:

[0295] S101: The base station sends a system information block indicating the combination of LP-WUS paging packets and PEI paging packets.

[0296] The system sends a System Information Block (SIB) instructing that LP-WUS and PEI be combined (LP-WUS and PEI coexist), and that LP-WUS wake-up parameters and PEI wake-up parameters be configured respectively (SIB LP-WUSconfig, PEI config).

[0297] For example, the UE can receive a first group configuration parameter and a second group configuration parameter sent by the base station. The first group configuration parameter may include the wake-up time for listening to the first wake-up signal, and the second group parameter may include the wake-up time for listening to the second wake-up signal. The first group configuration parameter may also include other related parameters for configuring the UE to listen to the first wake-up signal, without limitation. Correspondingly, the second group configuration parameter may also include other related parameters for configuring the UE to listen to the second wake-up signal, without limitation.

[0298] S102: The UE determines the number of LP-WUS paging packets based on the UE_ID.

[0299] The UE determines the first packet number, which is the total number of LP-WUS packets to be sent to the UE associated with the PO.

[0300] S103: UE startup registration.

[0301] After the UE powers on, it registers an RRC connection with the base station and receives the user identifier returned by the base station. The user identifier received here can be the third identifier mentioned in this embodiment, that is, the user identifier obtained by removing some bits of the UE's 5G-S-TMSI, or it can be the user identifier obtained by further hashing and mapping the obtained 5G-S-TMSI bits using a hash function (hash UE identity), and there is no limitation.

[0302] S104: The base station sends an RRC connection release signaling message, including the UE's first packet number.

[0303] The base station receives the RRC connection request registered by the UE after power-on, releases the RRC connection, and sends an RRC connection release signaling to the UE. The RRC connection release signaling includes the UE's first packet number, which indicates the first packet number (coexist group id) used in the coexisting packet scheme. The UE enters RRC_IDLE or RRC_Inactive if the UE meets the LP-WUS condition. In this case, the UE's LR listens for LP-WUS, MR is disabled, and it can enter a very deep sleep state.

[0304] After receiving the RRC, the UE can calculate its second packet number. The UE can calculate the second packet number using the PEI packet calculation formula. The PEI packet calculation formula includes:

[0305] PEISubgroupID=(floor(UE_ID / (N*Ns))modsubgroupsNumForUE_ID)+(subgroupsNumPerPO–subgroupsNumForUE_ID).

[0306] Wherein, PEISubgroup ID represents the UE's PEI group number, UE_ID is the UE's user identifier, N represents the number of PFs within a DRX period, and Ns represents the number of POs under a PF. subgroupsNumPerPO represents the total number of PO groups, which is the total number of PEI groups corresponding to all UEs associated with each PO. subgroupsNumForUE_ID represents the number of PO cell groups, which is the number of groups allocated by the cell in the PEI groups corresponding to all UEs associated with each PO. Normally, when performing PEI grouping on all UEs associated with a PO, the total number of PEI groups is determined. Of the total number of PEI groups, a portion is allocated by the core network and a portion is allocated by the cell. In the joint paging grouping scheme provided in this embodiment, the core network no longer occupies a portion of the PEI groups, that is, the number of groups allocated by the cell can be the total number of PO cell groups. Therefore, the difference between the total number of PO cell groups and the number of groups allocated by the cell may be 0.

[0307] In this embodiment, the first group number obtained by the UE is configured by the network device, and the second group number is calculated based on the UE_ID and the PEI grouping formula, which can make the first group number different from the second group number.

[0308] S105: The base station sends LP-WUS.

[0309] The base station begins paging and sends LP-WUS.

[0310] S106: The UE's LR detects LP-WUS, wakes up the MR, downloads the downlink synchronization signal, and determines when PEI monitoring is possible.

[0311] The base station sends LP-WUS, and the UE's LR listens to LP-WUS. The UE detects that the first packet number of the target UE indicated by LP-WUS includes the first packet number of the first terminal, and the UE wakes up its MR. The MR needs a certain amount of time to be woken up. After the MR is woken up, it determines whether there is still a PEI listening opportunity, that is, whether the PEI listening time has not yet arrived. If it has not arrived, it is determined that there is a PEI listening opportunity, and the MR listens for PEI during the PEI listening time.

[0312] S107: The base station sends PEI.

[0313] In this embodiment, when a UE in a certain LP-WUS group is woken up, only UEs that meet the following conditions can listen to PEI: the network has configured PEI parameters, the network carries the coexist group ID in the RRC RELEASE message, after the UE's group is woken up, the UE starts MR and completes DL SYNC, there is a corresponding PEI listening opportunity, and both PEI and LP-WUS are configured to use UE_ID based groups.

[0314] S108: UE listens to PEI.

[0315] The base station sends the PEI at the configured PEI listening time according to the configured PEI parameters, and the UE listens for the PEI at the corresponding PEI listening time. The UE then further determines whether the packet number of the second packet of the target UE indicated by the PEI includes the second packet number of the first terminal. If it does, the UE listens for the PO; otherwise, it does not need to listen for the PO.

[0316] Tables 3 and 4 below show examples of joint paging packet numbers based on network device configuration. If a network device simultaneously pages UE10 and UE14, where UE10 meets the conditions for joint use with PEI, the PEI packet number for UE10 is P2, and the PEI packet number for UE14 is P3. The second and third bits of the PEI bit count are set to 1, i.e., the PEI bit count is set to 00001100. The LP-WUS packet number for UE10 is L4, and the LP-WUS packet number for UE14 is L3. The third and fourth bits of the LP-WUS bit count are set to 1, i.e., the LP-WUS bit count is set to 00011000. In this case, UE10 and UE14 wake up the MR. Only UE10 listens to the PEI and listens for paging messages in its corresponding PO. Other UEs do not need to listen to the PEI or the paging messages in their corresponding PO.

[0320]

[0321]

[0322] In the communication method provided in this embodiment, the UE's LP-WUS packet number and PEI packet number are directly configured by the network device. Each UE, after determining that it meets the conditions for using the combined packet, determines the combined packet number of the target UE to be woken up by the network device based on the monitored LP-WUS and PEI, and then determines whether it needs to listen for paging messages at the corresponding PO. Direct configuration of the combined packet number by the network device saves the packet number calculation and verification operations on the UE side, improving the efficiency of paging response.

[0323] In addition, this application embodiment also provides a terminal, which includes a communication module, a memory and a processor. The communication module includes a low-power wake-up receiver and a main radio frequency receiver, which are coupled to the main radio frequency receiver. The main radio frequency receiver and the memory are both coupled to the processor.

[0324] The memory stores instructions that the computer executes;

[0325] The processor executes computer execution instructions stored in the memory, causing the terminal to perform the communication method provided in the above embodiments.

[0326] like Figure 11 The diagram shown is a hardware structure diagram of a terminal 1100 provided in an embodiment of this application, particularly a structural diagram of a UE (User Equipment) terminal. The terminal 1100 may include a processor 1110, an external memory interface 1120, a memory 1121, a Universal Serial Bus (USB) interface 1130, a charging management module 1140, a power management module 1141, a battery chip 1142, antenna 1, antenna 2, a mobile communication module 1150, a wireless communication module 1160, an audio module 1170, a speaker 1170A, a receiver 1170B, a microphone 1170C, a headphone jack 1170D, a sensor module 1180, buttons 1190, a motor 1191, an indicator 1192, a camera 1193, a display screen 1194, and a SIM card module 1195, etc. The sensor module 1180 may include a pressure sensor 1180A, a gyroscope sensor 1180B, a barometric pressure sensor 1180C, a magnetic sensor 1180D, an accelerometer sensor 1180E, a distance sensor 1180F, a proximity sensor 1180G, a fingerprint sensor 1180H, a temperature sensor 1180J, a touch sensor 1180K, an ambient light sensor 1180L, a bone conduction sensor 1180M, etc.

[0327] The structure illustrated in this embodiment of the invention does not constitute a limitation on terminal 1100. It may include more or fewer components than illustrated, or combine some components, or split some components, or have different component arrangements. The illustrated components may be implemented in hardware, software, or a combination of both.

[0328] Processor 1110 may include one or more processing units. For example, processor 1110 may include an application processor (AP), a modem processor, a graphics processing unit (GPU), an image signal processor (ISP), a controller, memory, a video codec, a digital signal processor (DSP), a baseband processor, and / or a neural network processing unit (NPU), etc. The different processing units may be independent devices or integrated into one or more processors.

[0329] The aforementioned controller can act as the decision-maker, directing the various components of terminal 1100 to coordinate their operations according to instructions. It serves as the nerve center and command center of terminal 1100. Based on the instruction opcode and timing signals, the controller generates operation control signals to control the fetching and execution of instructions.

[0330] The processor 1110 may also include a memory for storing instructions and data. In some embodiments, the memory in the processor 1110 is a cache memory, which can store instructions or data that the processor 1110 has just used or that are used repeatedly. If the processor 1110 needs to use the instruction or data again, it can retrieve it directly from the memory. This avoids repeated accesses, reduces the waiting time of the processor 1110, and thus improves the efficiency of the system.

[0331] In some embodiments, the processor 1110 may include interfaces. These interfaces may include an Inter-Integrated Circuit (I2C) interface, an Inter-Integrated Circuit Sound (I2S) interface, a Pulse Code Modulation (PCM) interface, a Universal Asynchronous Receiver / Transmitter (UART) interface, a Mobile Industry Processor Interface (MIPI) interface, a General-Purpose Input / Output (GPIO) interface, a SIM interface, and / or a USB interface, etc.

[0332] The interface connection relationships between the modules illustrated in this embodiment of the invention are merely illustrative and do not constitute a structural limitation on the terminal 1100. The terminal 1100 may employ different interface connection methods or a combination of multiple interface connection methods as described in this embodiment of the invention.

[0333] The charging management module 1140 can be a rechargeable battery or a disposable battery. If it is a rechargeable battery, it can receive charging input through a charger. The power management module 1141 is used to connect the battery chip 1142, the charging management module 1140, and the processor 1110. The power management module 1141 receives input from the battery chip 1142 and / or the charging management module 1140 to power the processor 1110, memory 1121, external memory interface 1120, display 1194, camera 1193, and wireless communication module 1160, etc.

[0334] The wireless communication function of terminal 1100 can be implemented through antenna 1, antenna 2, mobile communication module 1150, wireless communication module 1160, modem, and baseband processor.

[0335] Antenna 1 and antenna 2 are used to transmit and receive electromagnetic wave signals. Each antenna in terminal 1100 can be used to cover one or more communication frequency bands. Different antennas can also be multiplexed to improve antenna utilization. For example, a cellular antenna can be multiplexed as a wireless local area network diversity antenna. In some embodiments, the antenna can be used in conjunction with a tuning switch.

[0336] The mobile communication module 1150 provides a communication processing module for wireless communication solutions, including 2G / 3G / 4G / 5G, applied to the terminal 1100. The mobile communication module 1150 may include a low-power wake-up receiver (LR) and a main radio (MR). The LR has lower power consumption and can operate continuously, monitoring LP-WUS. In contrast, the MR has higher power consumption.

[0337] When the UE meets the conditions for listening to LP-WUS, it enters a deep sleep state. The LR listens for the low-power wake-up signal, and the MR is in a low-power state. When it is necessary to listen for paging or other information, the LR can wake up the MR, which will then listen for paging or other information.

[0338] In addition, the mobile communication module 1150 may also include at least one filter, switch, power amplifier, low noise amplifier (LNA), etc. The mobile communication module 1150 receives electromagnetic waves from the antenna 1 and performs filtering, amplification, and other processing on the received electromagnetic waves before transmitting them to the modem for demodulation. The mobile communication module 1150 may also amplify the signal modulated by the modem and convert it into electromagnetic waves for radiation via the antenna 1. In some embodiments, at least some functional modules of the mobile communication module 1150 may be housed in the processor 1110. In some embodiments, at least some functional modules of the mobile communication module 1150 and at least some modules of the processor 1110 may be housed in the same device.

[0339] A modem may include a modulator and a demodulator. The modulator modulates a low-frequency baseband signal to be transmitted into a mid-to-high frequency signal. The demodulator demodulates a received electromagnetic wave signal into a low-frequency baseband signal. The demodulator then transmits the demodulated low-frequency baseband signal to a baseband processor for processing. After processing by the baseband processor, the low-frequency baseband signal is transmitted to an application processor. The application processor outputs sound signals through an audio device (not limited to speaker 1170A, receiver 1170B, etc.) or displays images or videos through a display screen 1194. In some embodiments, the modem may be a standalone device. In some embodiments, the modem may be independent of the processor 1110 and may be housed in the same device as the mobile communication module 1150 or other functional modules.

[0340] The wireless communication module 1160 provides a communication processing module for solutions of wireless communication applied to the terminal 1100, including Wireless Local Area Networks (WLAN) (such as Wireless Fidelity (Wi-Fi) networks), Bluetooth (BT), Global Navigation Satellite System (GNSS), Frequency Fodulation (FM), Near Field Communication (NFC), and Infrared (IR) technologies. The wireless communication module 1160 can be one or more devices integrating at least one communication processing module. The wireless communication module 1160 receives electromagnetic waves via antenna 2, performs frequency modulation and filtering of the electromagnetic wave signals, and sends the processed signal to processor 1110. The wireless communication module 1160 can also receive signals to be transmitted from processor 1110, perform frequency modulation and amplification, and convert them into electromagnetic waves for radiation via antenna 2.

[0341] In some embodiments, antenna 1 of terminal 1100 is coupled to mobile communication module 1150, and antenna 2 is coupled to wireless communication module 1160, enabling terminal 1100 to communicate with networks and other devices via wireless communication technology. Wireless communication technologies may include Global System for Mobile Communications (GSM), General Packet Radio Service (GPRS), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), Time-Division Code Division Multiple Access (TD-SCDMA), Long Term Evolution (LTE), BT, GNSS, WLAN, NFC, FM, and / or IR technologies, etc. GNSS can include Global Positioning System (SBAS), Global Navigation Satellite System (GLONASS), BeiDou Navigation Satellite System (BDS), Quasi-Zenith Satellite System (QZSS), and / or Satellite Based Augmentation System (SBAS).

[0342] Terminal 1100 implements display functions through a GPU, display screen 1194, and application processor. The GPU is a microprocessor for image processing, connected to the display screen 1194 and the application processor. The GPU is used to perform mathematical and geometric calculations and for graphics rendering. Processor 1110 may include one or more GPUs, which execute program instructions to generate or modify display information.

[0343] The external storage interface 1120 can be used to connect an external storage card, such as a Micro SD card, to expand the storage capacity of the terminal 1100. The external storage card communicates with the processor 1110 through the external storage interface 1120 to perform data storage functions. For example, music, video, and other files can be saved on the external storage card.

[0344] Internal memory 1121 can be used to store computer executable program code, which includes instructions. Processor 1110 executes various functional applications and data processing of terminal 1100 by running the instructions stored in internal memory 1121. Memory 1121 may include a program storage area and a data storage area. The program storage area may store the operating system, at least one application program required for a function (such as sound playback, image playback, etc.), etc. The data storage area may store data created during the use of terminal 1100 (such as audio data, phonebook, etc.). Furthermore, memory 1121 may include high-speed random access memory, and may also include non-volatile memory, such as at least one disk storage device, flash memory device, other volatile solid-state storage devices, Universal Flash Storage (UFS), etc.

[0345] Terminal 1100 can implement audio functions, such as music playback and recording, through audio module 1170, speaker 1170A, receiver 1170B, microphone 1170C, headphone jack 1170D, and application processor.

[0346] The receiver 1170B, also known as the "earpiece," is used to convert audio electrical signals into sound signals. The microphone 1170C, also known as a "microphone" or "voice transducer," is used to convert sound signals into audio electrical signals. The headphone jack 1170D is used to connect wired headphones. Buttons 1190 include a power button, volume buttons, etc. Buttons 1190 can be mechanical buttons or touch buttons. The terminal 1100 receives input from buttons 1190 and generates key signal inputs related to user settings and function control of the terminal 1100. The motor 1191 can generate vibration prompts. The indicator 1192 can be an indicator light, used to indicate charging status, battery level changes, messages, missed calls, notifications, etc. The SIM card module 1195 is used to implement the communication functions of the SIM card; the SIM card module 1195 may include a SIM card interface, SIM card circuitry, and related auxiliary components.

[0347] The communication methods described in the foregoing embodiments can all be implemented in the terminal 1100 with the aforementioned hardware structure.

[0348] Furthermore, embodiments of this application also provide a network device, which includes a communication module, a memory, and a processor, wherein the communication module and the memory are both coupled to the processor;

[0349] The memory stores the instructions that the computer executes;

[0350] The processor executes computer execution instructions stored in the memory, causing the terminal to perform the communication method provided in the above embodiments.
