Description

[0001] This application is a divisional application of the invention patent application filed on December 1, 2021, with application number 202180004240.7 and entitled "Method, Apparatus, Communication Equipment and Storage Medium for Group Paging". Technical Field

[0002] This disclosure relates to, but is not limited to, the field of wireless communication technology, and particularly to a method, apparatus, communication device, and storage medium for packet paging. Background Technology

[0003] Paging is an important function in wireless communication. Its purpose is to instruct the base station to notify the paged terminal to respond to network requests. The base station and the terminal agree on a paging occasion (PO). The base station sends a paging message at the designated PO, and the terminal receives the message at the corresponding PO.

[0004] In related technologies, a group paging method is used to page terminals. The network can page all terminals within a group by sending a single paging message, without needing to send a separate paging message to each terminal. After receiving a group paging message, the terminal determines whether it belongs to the group being paged. If it does, it responds to the group paging message; otherwise, it ignores the message.

[0047] or,

[0055] In one embodiment, the method further includes:

[0056] In response to the fact that the number of paging packets allocated based on the predetermined method is greater than the number of paging packets supported by the base station for the predetermined method, a paging operation is performed using predetermined paging packet resources, wherein the predetermined paging packet resources are pre-configured;

Here, since mapping relationship information indicating the mapping relationship between paging packet information and paging packet resources can be sent to the terminal, the terminal can determine the paging packet resources of the paging packet based on the mapping relationship. Compared to the situation where the number of paging packets allocated by the network and the number of paging packets supported by the base station are inconsistent, making it impossible to determine the paging packet resources, this reduces paging failures caused by the inability to determine paging packet resources for paging monitoring, thus improving the reliability of packet paging.

[0092] Please refer to Figure 1 This illustration shows a schematic diagram of the structure of a wireless communication system provided in an embodiment of this disclosure. Figure 1 As shown, the wireless communication system is a communication system based on mobile communication technology. The wireless communication system may include: several user equipment 110 and several base stations 120.

[0093] User equipment 110 can be a device that provides voice and / or data connectivity to a user. User equipment 110 can communicate with one or more core networks via a Radio Access Network (RAN). User equipment 110 can be an Internet of Things (IoT) user equipment, such as sensor devices, mobile phones, and computers with IoT user equipment capabilities. For example, it can be a fixed, portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted device. Examples include a station (STA), subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, user agent, user device, or user equipment. Alternatively, user equipment 110 can also be a device from an unmanned aerial vehicle (UAV). Alternatively, user equipment 110 can also be a vehicle-mounted device, such as a vehicle computer with wireless communication capabilities, or a wireless user equipment connected to an external vehicle computer. Alternatively, user equipment 110 can also be a roadside device, such as a street light, traffic light, or other roadside device with wireless communication capabilities.

[0094] Base station 120 can be a network-side device in a wireless communication system. This wireless communication system can be a fourth-generation mobile communication (4G) system, also known as a Long Term Evolution (LTE) system; or it can be a 5G system, also known as a New Radio (NR) system; or it can be the next generation after 5G. In this case, the access network in the 5G system can be called NG-RAN (New Generation-Radio Access Network).

[0095] The base station 120 can be an evolved NB (eNB) used in a 4G system. Alternatively, the base station 120 can also be a gNB (gNB) using a centralized-distributed architecture in a 5G system. When the base station 120 adopts a centralized-distributed architecture, it typically includes a central unit (CU) and at least two distributed units (DUs). The central unit is equipped with a protocol stack of the Packet Data Convergence Protocol (PDCP) layer, the Radio Link Control (RLC) layer, and the Media Access Control (MAC) layer; the distributed units are equipped with a physical (PHY) layer protocol stack. This disclosure does not limit the specific implementation of the base station 120.

[0096] Base station 120 and user equipment 110 can establish a wireless connection via a wireless air interface. In different implementations, the wireless air interface is a wireless air interface based on the fourth-generation mobile communication network technology (4G) standard; or, the wireless air interface is a wireless air interface based on the fifth-generation mobile communication network technology (5G) standard, such as a new air interface; or, the wireless air interface can also be a wireless air interface based on a next-generation mobile communication network technology standard based on 5G.

[0097] In some embodiments, user equipment 110 can also establish E2E (End to End) connections. Examples include V2V (vehicle to vehicle), V2I (vehicle to Infrastructure), and V2P (vehicle to pedestrian) communication scenarios in vehicle-to-everything (V2X) communication.

[0098] Here, the user equipment mentioned above can be considered as the terminal equipment in the following embodiments.

[0099] In some embodiments, the wireless communication system described above may further include a network management device 130.

[0100] Several base stations 120 are connected to network management device 130. Network management device 130 can be a core network device in a wireless communication system, such as a Mobility Management Entity (MME) in an Evolved Packet Core (EPC). Alternatively, it can be other core network devices, such as a Serving Gateway (SGW), a Public Data Network Gateway (PGW), a Policy and Charging Rules Function (PCRF), or a Home Subscriber Server (HSS). The implementation of network management device 130 is not limited in this embodiment.

[0101] To facilitate understanding by those skilled in the art, this disclosure provides multiple embodiments to clearly illustrate the technical solutions of the embodiments of this disclosure. Of course, those skilled in the art will understand that the multiple embodiments provided in this disclosure can be executed individually, or in combination with the methods of other embodiments in this disclosure, or individually or in combination with some methods in other related technologies; this disclosure does not limit these aspects.

[0102] To better understand the technical solutions described in any embodiment of this disclosure, the scenario of a group paging terminal in the related art will first be explained:

[0103] In one embodiment, without paging grouping, all terminals will be woken up at the paging time. In another embodiment, since the probability of terminals being paged within the corresponding time period at the paging time is different, terminals with low paging probability will also be wrongly woken up, causing unnecessary power consumption. Therefore, it is necessary to paging groups the terminals and use paging grouping to page the terminals.

[0104] In one embodiment, paging packet information can be carried in downlink control information (DCI) or paging early indication (PEI). Regardless of the packet method used, the terminal and the network (including the base station and core network) need to agree on the packet to which the terminal belongs in order to send the paging message to the terminal normally.

[0105] In one embodiment, a random method for determining groups based on the modulo of the UE-ID is provided. A paging group can be obtained by taking the modulo of the UE-ID, and the formula is as follows:

[0106]

[0107] Where, N w The total number of paging packet resources is represented by wg, which is the index of the selected paging packet resource.

[0108] The UE-ID modulo method is either random selection or random allocation. That is, the modulo is taken from all paging packet resources according to the UE-ID. Here, N is the paging frame density in the time domain, and Ns is the paging density within a single paging frame in the time domain; Nn is the paging narrowband; and Nw is the total number of paging packet resources.

[0109] In one embodiment, the network configures terminal paging packets by the core network. Here, unlike the probability allocation method in LTE, packet IDs are directly allocated in NR. In this case, the network allocates the packet ID based on implementation requirements, such as terminal attributes or statistical paging probabilities.

[0110] In one embodiment, if the core network does not provide a packet ID to the terminal, the terminal will fall back to the random selection of paging packet resources based on the UE-ID.

[0111] Therefore, there can be considered to be two paging packet methods: one based on network allocation, and the other based on a random UE-ID. In one embodiment, the base station needs to notify the terminal which method is supported, so that the base station and the terminal can determine which packet to use and select paging packet resources to achieve consistency. If neither method is supported, the terminal will perform paging listening based on the unsupported paging packet method.

[0112] In one embodiment, a base station can simultaneously support two packet modes, and the packets from the two modes do not overlap. Therefore, there may be instances where the total number of packets supported by the base station for the core network is insufficient to support the maximum number of packets in the core network. Consequently, the base station may need to consider how to map core network packets to the Layer 1 packets that the base station can support.

[0113] like Figure 2 As shown, this embodiment provides a method for group paging, wherein the method is executed by a base station and includes:

[0114] Step 21: Send mapping relationship information to the terminal;

[0115] Among them, the mapping relationship information indicates the mapping relationship between paging packet information and paging packet resources.

[0116] In one embodiment, the mapping information may be a mapping relationship between information used by the terminal to determine paging packets and paging packet resources. This instructs the terminal on how to map paging packets to paging packet resources.

[0117] In one embodiment, it may be determined whether to send mapping information to the terminal based on the number of paging packets allocated according to a predetermined method and the number of paging packets supported by the base station for the predetermined method, wherein the predetermined method is the method by which the network allocates paging packets.

[0118] Here, the terminal may be, but is not limited to, a mobile phone, wearable device, vehicle terminal, roadside unit (RSU), smart home terminal, industrial sensing device and / or medical device, etc.

[0119] The base station mentioned in this disclosure can be an access device for a terminal to access a network. Here, the base station can be of various types, such as a base station for a third-generation (3G) mobile communication network, a base station for a fourth-generation (4G) mobile communication network, a base station for a fifth-generation (5G) mobile communication network, or other evolved base stations. Here, the base station can simultaneously support both network-allocated paging packets and randomly allocated paging packets.

[0120] In one embodiment, group paging can be as follows: terminals are divided into different groups; the network pagees all terminals within a group by sending a group paging message, without needing to send a paging message for each terminal individually; after receiving the group paging message, the terminal determines whether it belongs to the group being paged; if it belongs to the group being paged, it responds to the group paging message; if it does not belong to the group being paged, it ignores the group paging message.

[0121] In one embodiment, there can be multiple packets for packet paging. These different packets may be configured with different paging resources. The terminal may belong to one of these multiple packets. Upon determination of the paging packet to which the terminal belongs, the terminal can listen for paging messages on the paging resources indicated by the paging packet. Here, the packet to which the terminal belongs may be determined based on a UE-ID modulo method or by a core network device within the core network. It should be noted that a predefined packet can also be divided into multiple sub-paging packets. Of course, the "packet" here can refer to a sub-paging packet, and is not limited thereto. The paging packets in this disclosure can be the same as the packets used for packet paging.

[0122] In one embodiment, the number of paging packets allocated based on a predetermined method is different from the number of paging packets supported by the base station for the predetermined method. In one embodiment, if the number of paging packets allocated based on the predetermined method is greater than the number of paging packets supported by the base station for the predetermined method, it is determined that mapping relationship information will be sent to the terminal; or, if the number of paging packets allocated based on the predetermined method is not greater than the number of paging packets supported by the base station for the predetermined method, it is determined that the mapping relationship information will not be sent to the terminal. It should be noted that if the number of paging packets allocated based on the predetermined method is not greater than the number of paging packets supported by the base station for the predetermined method, it is also possible to determine that the mapping relationship information will be sent to the terminal.

[0123] Here, the number of paging packets supported by the base station for the predetermined method can correspond to the number of paging packet resources that can be provided. It is understood that the term "greater than" also encompasses the meaning of "greater than or equal to," and "less than" also encompasses the meaning of "less than or equal to."

[0124] In one embodiment, the number of paging packets allocated based on a predetermined method may be allocated by the core network, and the base station may receive the number of paging packets allocated based on the predetermined method sent by the core network. Based on the number of paging packets allocated based on the predetermined method and the number of paging packets supported by the base station for the predetermined method, it is determined whether to send mapping relationship information to the terminal. Here, the number of paging packets allocated based on the predetermined method can be understood as the maximum number of paging packets allocated by the network.

[0125] In one embodiment, the number of paging packets supported by the base station for allocation in a predetermined manner may be allocated by the base station. After determining the number of paging packets allocated for the predetermined manner, the base station determines whether to send mapping relationship information to the terminal based on the number of paging packets allocated based on the predetermined manner and the number of paging packets supported by the base station for the predetermined manner.

[0126] It should be noted that the number of paging packets supported by the base station for the predetermined method is the number determined according to the predetermined protocol rules; or, the number of paging packets supported by the base station for the predetermined method is the total number of paging packets supported by the base station. For example, the paging packets supported by the base station may be paging packets of supported Layer 1.

[0127] In one embodiment, the quantity information can indicate how the base station supports network allocation of paging packets. That is, after the terminal receives the quantity information, it can determine, based on the quantity information, that the base station supports configuring paging packets according to a predetermined method.

[0128] In one embodiment, after determining the number of paging packets supported by the base station for a predetermined method, the base station may send data information to the terminal. Exemplarily, this could involve sending first quantity information to the terminal, where the first quantity information carries a value indicating the number of paging packets supported by the base station for the predetermined method. For example, if the quantity value N = 4, the first quantity information can explicitly indicate the number of paging packets supported by the base station for the predetermined method. Alternatively, second quantity information can be sent to the terminal, where the second quantity information instructs the terminal to determine the number of paging packets supported by the base station for the predetermined method based on the quantity obtained in the target method. For example, if the base station supports determining paging packets through random packet generation (such as UE-ID modulo method, the target method) and network allocation (the predetermined method), and the maximum number of paging packets supported by the base station based on different methods is 8, then after the terminal determines that the number of paging packets determined through random packet generation is 4, the terminal can determine that the number of paging packets based on network allocation is 4. Thus, the second quantity information can implicitly indicate that the number of paging packets supported by the base station for the predetermined method is 4. In one embodiment, when the information field of the second data information indicates a predetermined value, it indicates that the terminal determines the number of paging packets supported by the base station for the predetermined mode based on the quantity obtained in the target mode.

[0129] In one embodiment, the base station sends the number of paging packets supported by the base station for a predetermined method to the terminal, so that the terminal can determine the mapping relationship between paging packet information and paging packet resources; after obtaining the number of paging packets, the terminal can establish the mapping relationship between paging packet information and paging packet resources through protocol agreement.

[0130] In one embodiment, if the base station can determine the maximum number of paging packets allocated by the core network, and the base station can also provide a sufficient number of paging packets to support the packet mode, then the base station only needs to notify the terminal of the number of paging packets that the base station can support for the predetermined mode. For example, if the base station notifies the terminal of 8 packets, then the maximum number of paging packets allocated from the core network will not exceed 8, and the terminal can always find the corresponding paging packet resource according to a one-to-one mapping. Alternatively, the base station can notify the terminal of the number of paging packets that the base station can support for the predetermined mode through an explicit indication (such as a flag indication), and the terminal can always find the corresponding paging packet resource according to a one-to-one mapping.

[0131] In one embodiment, the base station may only provide the number of paging packets to support this paging packet method. For example, if the base station notifies that the number of paging packets is 4, then the maximum number of paging packets allocated from the core network may exceed 4 or not exceed 4. The terminal can always find the corresponding paging packet resource using a one-to-one mapping. For example, if the maximum number of paging packets allocated by the core network is no more than 4, the terminal can find the corresponding paging packet resource using a one-to-one mapping; if the number of paging packets allocated by the core network exceeds 4, the terminal can map the excess paging packets to the last paging packet resource. It should be noted that the last paging packet resource can be a paging packet resource that is ranked later in the sequence.

[0132] In one embodiment, the base station sends to the terminal the number of paging packets supported by the base station for a predetermined method and the number of paging packets allocated by the network, so that the terminal can determine the mapping relationship between paging packet information and paging packet resources; after receiving the number of paging packets, the terminal establishes the mapping relationship between paging packet information and paging packet resources through protocol agreement.

[0133] For example, the base station supports two paging packets: a first paging packet and a second paging packet. The core network allocates four paging packets: a first paging packet, a second paging packet, a third paging packet, and a fourth paging packet. The first and second paging packets can be mapped to the first and second paging packet resources, respectively, and the remaining two paging packets can be mapped to the last paging packet resource.

[0134] In one embodiment, the predetermined mapping relationship can be a mapping relationship determined according to a formula. For example, the paging packet resources corresponding to the paging packets can be determined in an equal-division manner.

[0135] For example, the base station supports two paging packets: a first paging packet and a second paging packet, corresponding to two paging packet resources. The total number of paging packet resources is eight, namely, the first paging packet resource, the second paging packet resource, ..., the eighth paging packet resource. Therefore, the paging packet resources can be evenly distributed, mapping the first to fourth paging packet resources to the first paging packet, and mapping the fifth to eighth paging packet resources to the second paging packet. It should be noted that this distribution method is not limited to the above even distribution; arbitrarily selected paging packet resources can also be evenly distributed to allocate to the first and second paging packets.

[0136] For example, the base station supports two paging packets: a first paging packet and a second paging packet, corresponding to two paging packet resources. If there are seven paging packets in total, namely the first paging packet, the second paging packet, ..., the seventh paging packet, then the first to fourth paging packets can be mapped to the first paging packet resources, and the remaining three can be mapped to the second paging packet resources. It should be noted that this is not limited to the above equal allocation method; arbitrarily selected paging packet resources can also be evenly allocated to the first and second paging packets.

[0137] For example, the base station supports two paging packets: a first paging packet and a second paging packet, corresponding to two paging packet resources. If there are seven paging packets in total, namely the first paging packet, the second paging packet, ..., the seventh paging packet, then the first to the third paging packets can be mapped to the first paging packet resource, and the remaining four can be mapped to the second paging packet resource. It should be noted that this is not limited to the above equal distribution method; arbitrarily selected paging packets can also be evenly distributed to the first and second paging packets.

[0138] In the above embodiments, the base station does not need to provide an explicit mapping relationship, but only needs to provide the number of paging packets supported by the base station for a predetermined method and / or the number of paging packets allocated by the network, so that the terminal can determine the mapping relationship.

[0139] In one embodiment, a mapping relationship is established between paging packet information and paging packet resources. Based on the number of paging packets allocated according to a predetermined method and the number of paging packets supported by the base station for the predetermined method, it is determined whether to send mapping relationship information to the terminal. Here, the mapping relationship information indicates the mapping relationship.

[0140] In one embodiment, a mapping relationship may be established between a single paging packet and a resource set including at least one paging packet resource. For example, the mapping relationship may be a relationship between a single paging packet and a single paging packet resource, as shown in Table 1:

[0141] Table 1: One-to-one relationships

[0142] Subgroup0 Paging group radio resource 0 Subgroup1 Paging group radio resource 1 … …

[0143] For example, the mapping relationship can be a relationship where a single paging packet corresponds to multiple paging packet resources, as shown in Table 2:

[0144] Table 2: One-to-many relationships

[0145]

[0146] In one embodiment, a mapping relationship may be established between a set of groups containing multiple paging packets and a resource set containing at least one paging packet resource. For example, the mapping relationship may be a relationship where multiple paging packets correspond to multiple paging packet resources, as shown in Table 3.

[0147] Table 3. Many-to-many relationships

[0148]

[0149] In the above embodiments, the base station needs to explicitly notify the terminal of its mapping relationship.

[0150] In this embodiment, mapping relationship information is sent to the terminal, wherein the mapping relationship information indicates the mapping relationship between paging packet information and paging packet resources. Here, since mapping relationship information indicating the mapping relationship between paging packet information and paging packet resources can be sent to the terminal, the terminal can determine the paging packet resources of the paging packet based on the mapping relationship. Compared to the situation where the number of paging packets allocated by the network and the number of paging packets supported by the base station are inconsistent, making it impossible to determine the paging packet resources, this reduces paging failures caused by the inability to determine paging packet resources for paging monitoring, thus improving the reliability of packet paging.

[0151] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0152] This embodiment provides a method for packet paging, wherein the method is executed by a base station, and the method includes: determining whether to send mapping relationship information to a terminal based on the number of paging packets allocated according to a predetermined method and the number of paging packets supported by the base station for the predetermined method, wherein the mapping relationship information indicates the mapping relationship between paging packet information and paging packet resources; the predetermined method is the method of network allocation of paging packets.

[0153] like Figure 3 As shown, this embodiment provides a method for group paging, wherein the method is executed by a base station and includes:

[0154] Step 31: In response to the fact that the number of paging packets allocated based on the predetermined method is greater than the number of paging packets supported by the base station for the predetermined method, determine to send mapping relationship information to the terminal;

[0155] or,

[0156] In response to the fact that the number of paging packets allocated based on a predetermined method is not greater than the number of paging packets supported by the base station for the predetermined method, it is determined not to send the mapping relationship information to the terminal.

[0157] Here, the mapping information indicates the mapping relationship between paging packet information and paging packet resources.

[0158] In one embodiment, after obtaining the number of paging packets allocated according to a predetermined method and determining the number of paging packets supported by the base station for the predetermined method, the base station compares the number of paging packets allocated according to the predetermined method with the number of paging packets supported by the base station for the predetermined method. For example, if the number of paging packets allocated according to the predetermined method is greater than the number of paging packets supported by the base station for the predetermined method, it is determined to send mapping relationship information to the terminal; or, if the number of paging packets allocated according to the predetermined method is not greater than the number of paging packets supported by the base station for the predetermined method, it is determined not to send the mapping relationship information to the terminal. It should be noted that if the number of paging packets allocated according to the predetermined method is not greater than the number of paging packets supported by the base station for the predetermined method, it is also possible to determine to send mapping relationship information to the terminal; this is not a limitation in this disclosure.

[0159] In one embodiment, the base station pre-establishes a mapping relationship between paging packet information and paging packet resources. After the mapping relationship is established, in response to the number of paging packets allocated according to a predetermined method being greater than the number of paging packets supported by the base station for the predetermined method, it is determined to send the mapping relationship information to the terminal; or, in response to the number of paging packets allocated according to the predetermined method not being greater than the number of paging packets supported by the base station for the predetermined method, it is determined not to send the mapping relationship information to the terminal. It should be noted that if the number of paging packets allocated according to the predetermined method is not greater than the number of paging packets supported by the base station for the predetermined method, it is also possible to determine to send the mapping relationship information to the terminal; this is not a limitation in this disclosure.

[0160] In one embodiment, sending mapping relationship information to the terminal can be done by broadcasting the mapping relationship information to the terminal.

[0161] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0162] like Figure 4 As shown, this embodiment provides a method for group paging, wherein the method is executed by a base station and includes:

[0163] Step 41: Send quantity information to the terminal, wherein the quantity information indicates the number of paging packets supported by the base station for the predetermined method.

[0164] In one embodiment, quantity information may be sent to the terminal using Radio Resource Control (RRC) messages.

[0165] In one embodiment, quantity information may be sent to the terminal after determining the number of paging packets supported by the base station for a predetermined method.

[0166] In one embodiment, a first quantity information is sent to the terminal, wherein the first quantity information carries the quantity value of paging packets supported by the base station for a predetermined method. For example, the information field of the first quantity information is configured such that when the value of the information field is "011", the first quantity information carries the quantity value of 3 supported by the base station for the predetermined method; when the value of the information field is "100", the first quantity information carries the quantity value of 4 supported by the base station for the predetermined method.

[0167] In one embodiment, a second quantity information is sent to the terminal, wherein the second quantity information indicates that the terminal determines the number of paging packets supported by the base station for a predetermined method based on the quantity obtained by the target method. For example, the information field of the second quantity information is configured such that when the information field is set to "1" and the maximum number of paging packets supported by both random packet generation (such as UE-ID modulo method, which is the target method) and network allocation method (predetermined method) is 8, after the terminal determines that the number of paging packets determined by random packet generation is 4, the terminal can then determine that the number of paging packets based on network allocation is 4. Thus, the second quantity information can implicitly indicate that the number of paging packets supported by the base station for the predetermined method is 4. Here, the target method can be the random packet generation method.

[0168] Here, the number of paging packets supported by the base station for the predetermined mode is the number determined according to the predetermined protocol rules; or, the number of paging packets supported by the base station for the predetermined mode is the total number of paging packets supported by the base station.

[0169] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0170] like Figure 5 As shown, this embodiment provides a method for group paging, wherein the method is executed by a base station and includes:

[0171] Step 51: Send first quantity information to the terminal, wherein the first quantity information carries the quantity value of paging packets supported by the base station for the predetermined method;

[0172] or,

[0173] Send a second quantity information to the terminal, wherein the second quantity information indicates that the terminal determines the number of paging packets for the predetermined mode supported by the base station based on the quantity obtained in the target mode.

[0174] Here, the number of paging packets supported by the base station for the predetermined mode is the number determined according to the predetermined protocol rules; or, the number of paging packets supported by the base station for the predetermined mode is the total number of paging packets supported by the base station.

[0175] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0176] like Figure 6 As shown, this embodiment provides a method for group paging, wherein the method is executed by a base station and includes:

[0177] Step 61: Establish the mapping relationship between paging packet information and paging packet resources.

[0178] In one embodiment, a mapping relationship between paging packet information and paging packet resources may be pre-established. This mapping relationship information is then sent to the terminal. Here, the mapping relationship information indicates the mapping relationship.

[0179] In one embodiment, a mapping relationship between paging packet information and paging packet resources may be pre-established. Whether to send the mapping relationship information to the terminal is determined based on the number of paging packets allocated according to a predetermined method and the number of paging packets supported by the base station for the predetermined method.

[0180] In one embodiment, the mapping relationship can be a mapping relationship between a single paging packet and a resource set that includes at least one of the paging packet resources.

[0181] In one embodiment, the mapping relationship can be a mapping relationship between a set of groups containing multiple paging packets and a resource set containing at least one of the paging packet resources.

[0182] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0183] like Figure 7 As shown, this embodiment provides a method for group paging, wherein the method is executed by a base station and includes:

[0184] Step 71: Establish a mapping relationship between a single paging packet and a resource set that includes at least one paging packet resource;

[0185] or,

[0186] Establish a mapping relationship between a set of groups containing multiple paging packets and a set of resources containing at least one paging packet resource.

[0187] Here, paging packet resources can be time-domain resources and / or frequency-domain resources used for paging monitoring.

[0188] In one embodiment, the resource set may contain one or more paging packet resources, as described in Tables 1 and 2.

[0189] In one embodiment, a group set may contain multiple paging packets, and a resource set may contain multiple paging packet resources, as described in Section 3 of Table 3.

[0190] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0191] like Figure 8 As shown, this embodiment provides a method for group paging, wherein the method is executed by a terminal, and the method includes:

[0192] Step 81: Receive the mapping relationship information sent by the base station;

[0193] Among them, the mapping relationship information indicates the mapping relationship between paging packet information and paging packet resources.

[0194] Here, the terminal may be, but is not limited to, a mobile phone, wearable device, vehicle terminal, roadside unit (RSU), smart home terminal, industrial sensing device and / or medical device, etc.

[0195] The base station mentioned in this disclosure can be an access device for a terminal to access a network. Here, the base station can be of various types, such as a base station for a third-generation (3G) mobile communication network, a base station for a fourth-generation (4G) mobile communication network, a base station for a fifth-generation (5G) mobile communication network, or other evolved base stations. Here, the base station can simultaneously support both network-allocated paging packets and randomly allocated paging packets.

[0196] In one embodiment, group paging can be as follows: terminals are divided into different groups; the network pagees all terminals within a group by sending a group paging message, without needing to send a paging message for each terminal individually; after receiving the group paging message, the terminal determines whether it belongs to the group being paged; if it belongs to the group being paged, it responds to the group paging message; if it does not belong to the group being paged, it ignores the group paging message.

[0197] In one embodiment, there can be multiple paging groups. These different groups may be configured with different paging resources. The terminal may belong to one of these multiple groups. Upon determination of the paging group to which the terminal belongs, the terminal can listen for paging messages on the paging resources indicated by the paging group. Here, the group to which the terminal belongs may be determined based on a UE-ID modulo method or by a core network device within the core network. It should be noted that a predefined group can also be divided into multiple sub-paging groups. Of course, the group referred to here can refer to a sub-paging group, and this is not limited to that.

[0198] In one embodiment, the predetermined method is the method by which the network allocates paging packets. The number of paging packets allocated based on the predetermined method is different from the number of paging packets supported by the base station for the predetermined method. In one embodiment, if the number of paging packets allocated based on the predetermined method is greater than the number of paging packets supported by the base station for the predetermined method, the base station determines to send mapping relationship information to the terminal; or, if the number of paging packets allocated based on the predetermined method is not greater than the number of paging packets supported by the base station for the predetermined method, the base station determines not to send the mapping relationship information to the terminal. It should be noted that if the number of paging packets allocated based on the predetermined method is not greater than the number of paging packets supported by the base station for the predetermined method, the base station may also determine to send the mapping relationship information to the terminal. Here, the number of paging packets supported by the base station for the predetermined method may correspond to the number of paging packet resources that can be provided. It is understood that the term "greater than" also includes the meaning of "greater than or equal to", and "less than" also includes the meaning of "less than or equal to".

[0199] In one embodiment, the number of paging packets allocated based on a predetermined method may be allocated by the core network, and the base station may receive the number of paging packets allocated based on the predetermined method sent by the core network. The base station determines whether to send mapping relationship information to the terminal based on the number of paging packets allocated based on the predetermined method and the number of paging packets supported by the base station for the predetermined method. Here, the number of paging packets allocated based on the predetermined method can be understood as the maximum number of paging packets allocated by the network.

[0200] In one embodiment, the number of paging packets supported by the base station for allocation in a predetermined manner may be allocated by the base station. After determining the number of paging packets allocated for the predetermined manner, the base station determines whether to send mapping relationship information to the terminal based on the number of paging packets allocated based on the predetermined manner and the number of paging packets supported by the base station for the predetermined manner.

[0201] It should be noted that the number of paging packets supported by the base station for the predetermined method is the number determined according to the predetermined protocol rules; or, the number of paging packets supported by the base station for the predetermined method is the total number of paging packets supported by the base station. For example, the paging packets supported by the base station may be paging packets of supported Layer 1.

[0202] In one embodiment, the quantity information can indicate how the base station supports network allocation of paging packets. That is, after the terminal receives the quantity information, it can determine, based on the quantity information, that the base station supports configuring paging packets according to a predetermined method.

[0203] In one embodiment, after determining the number of paging packets supported by the base station for a predetermined method, the base station may send data information to the terminal. Exemplarily, this could involve sending first quantity information to the terminal, where the first quantity information carries a value indicating the number of paging packets supported by the base station for the predetermined method. For example, if the quantity value N = 4, the first quantity information can explicitly indicate the number of paging packets supported by the base station for the predetermined method. Alternatively, second quantity information can be sent to the terminal, where the second quantity information instructs the terminal to determine the number of paging packets supported by the base station for the predetermined method based on the quantity obtained in the target method. For example, if the base station supports determining paging packets through random packet generation (such as UE-ID modulo method, the target method) and network allocation (the predetermined method), and the maximum number of paging packets supported by the base station based on different methods is 8, then after the terminal determines that the number of paging packets determined through random packet generation is 4, the terminal can determine that the number of paging packets based on network allocation is 4. Thus, the second quantity information can implicitly indicate that the number of paging packets supported by the base station for the predetermined method is 4. In one embodiment, when the information field of the second data information indicates a predetermined value, it indicates that the terminal determines the number of paging packets supported by the base station for the predetermined mode based on the quantity obtained in the target mode.

[0204] In one embodiment, the base station establishes a mapping relationship between paging packet information and paging packet resources. The base station determines whether to send the mapping relationship information to the terminal based on the number of paging packets allocated according to a predetermined method and the number of paging packets supported by the base station for the predetermined method. Here, the mapping relationship information indicates the mapping relationship.

[0205] In one embodiment, the base station may establish a mapping relationship between a single paging packet and a resource set including at least one paging packet resource. Exemplarily, the mapping relationship may be a relationship where a single paging packet corresponds to a single paging packet resource. Exemplarily, the mapping relationship may be a relationship where a single paging packet corresponds to multiple paging packet resources.

[0206] In one embodiment, the base station may establish a mapping relationship between a set of groups containing multiple paging packets and a resource set containing at least one paging packet resource. For example, the mapping relationship may be a relationship where multiple paging packets correspond to multiple paging packet resources.

[0207] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0208] like Figure 9 As shown, this embodiment provides a method for group paging, wherein the method is executed by a terminal, and the method includes:

[0209] Step 91: Receive quantity information sent by the base station, wherein the quantity information indicates the number of paging packets supported by the base station for the predetermined method.

[0210] In one embodiment, the receiving base station may use Radio Resource Control (RRC) messages to send quantity information to the terminal.

[0211] In one embodiment, the base station may send quantity information to the terminal after determining the number of paging packets supported by the base station for a predetermined method.

[0212] In one embodiment, a first quantity information is received from a base station, wherein the first quantity information carries a quantity value of paging packets supported by the base station for a predetermined method. For example, the information field of the first quantity information is configured such that when the value of the information field is "011", the quantity value of the first quantity information supported by the base station for the predetermined method is 3; when the value of the information field is "100", the quantity value of the first quantity information supported by the base station for the predetermined method is 4.

[0213] In one embodiment, the terminal receives second quantity information sent by the base station, wherein the second quantity information indicates that the terminal determines the number of paging packets supported by the base station for a predetermined method based on the quantity obtained by the target method. For example, the information field of the second quantity information is configured such that when the information field is set to "1" and the maximum number of paging packets supported by both random packet generation (such as UE-ID modulo method, which is the target method) and network allocation method (predetermined method) is 8, after the terminal determines that the number of paging packets determined by random packet generation is 4, the terminal can then determine that the number of paging packets based on network allocation is 4. Thus, the second quantity information can implicitly indicate that the number of paging packets supported by the base station for the predetermined method is 4. Here, the target method can be the random packet generation method.

[0214] Here, the number of paging packets supported by the base station for the predetermined mode is the number determined according to the predetermined protocol rules; or, the number of paging packets supported by the base station for the predetermined mode is the total number of paging packets supported by the base station.

[0215] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0216] like Figure 10 As shown, this embodiment provides a method for group paging, wherein the method is executed by a terminal, and the method includes:

[0217] Step 101: Receive first quantity information sent by the base station, wherein the first quantity information carries the quantity value of paging packets supported by the base station for a predetermined method;

[0218] or,

[0219] The terminal receives second quantity information sent by the base station, wherein the second quantity information indicates that the terminal determines the number of paging packets supported by the base station for the predetermined mode based on the quantity obtained in the target mode.

[0220] Here, the number of paging packets supported by the base station for the predetermined mode is the number determined according to the predetermined protocol rules; or, the number of paging packets supported by the base station for the predetermined mode is the total number of paging packets supported by the base station.

[0221] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0222] In one embodiment, the mapping relationship includes:

[0223] The mapping relationship between a single paging packet and a resource set that includes at least one of the paging packet resources;

[0224] or,

[0225] A mapping relationship between a set of groups containing multiple of the paging packets and a resource set containing at least one of the paging packet resources.

[0226] In one embodiment, the resource set may contain one or more paging packet resources, as described in Tables 1 and 2.

[0227] In one embodiment, a group set may contain multiple paging packets, and a resource set may contain multiple paging packet resources, as described in Section 3 of Table 3.

[0228] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0229] like Figure 11 As shown, this embodiment provides a method for group paging, wherein the method is executed by a terminal, and the method includes:

[0230] Step 111: Determine the paging group resources used by the terminal for paging based on the mapping relationship indicated by the paging group and mapping relationship information to which the terminal belongs;

[0231] or,

[0232] Based on the paging group to which the terminal belongs and the predetermined mapping relationship, the paging group resources used by the terminal for paging are determined, wherein the predetermined mapping relationship is pre-configured; in one embodiment, the predetermined mapping relationship is pre-agreed by the protocol.

[0233] or,

[0234] The paging packet resources used by the terminal for paging are determined based on the paging packet to which the terminal belongs, the mapping relationship indicated by the mapping relationship information, and / or the predetermined mapping relationship.

[0235] In one embodiment, the mapping relationship is a sequential mapping, as detailed in Table 1. The paging group order is Subgroup0, Subgroup1, ...; the paging group resource order is radio resource 0, radio resource 1, ...; therefore, Subgroup0 maps to radio resource 0; and Subgroup1 maps to radio resource 1. Thus, after the terminal determines its paging group, the paging resources mapped to that paging group can be determined based on the information of that paging group.

[0236] In one embodiment, if there is insufficient paging packet resources, mapping is performed using the default method. Here, the default method can be a predefined method.

[0237] For example, the base station supports two paging packets for a predetermined method: a first paging packet and a second paging packet. If there are four paging packets, the first paging packet and the second paging packet are mapped to the first and second paging packet resources, respectively, and the remaining two paging packets are mapped to the last paging packet resource.

[0238] In one embodiment, the predetermined mapping relationship can be a mapping relationship determined according to a formula. For example, the paging resources corresponding to paging packets can be determined in an equal-division manner.

[0239] For example, the base station supports two paging packets: a first paging packet and a second paging packet, corresponding to two paging packet resources. Alternatively, if there are eight paging packets in total, namely the first paging packet, the second paging packet, ..., the eighth paging packet, then the paging resources can be evenly distributed. The first to fourth paging packets can be mapped to the first paging packet resource, and the fifth to eighth paging packets can be mapped to the second paging packet resource. It should be noted that this distribution method is not limited to the above even distribution method; arbitrarily selected paging packets can also be evenly distributed to the first and second paging packets.

[0240] For example, the base station supports two paging packets: a first paging packet and a second paging packet, corresponding to two paging packet resources. If there are seven paging packets in total, namely the first paging packet, the second paging packet, ..., the seventh paging packet, then the first to fourth paging packets can be mapped to the first paging packet resource, and the remaining three can be mapped to the second paging packet resource. It should be noted that this is not limited to the above equal distribution method; arbitrarily selected paging packets can also be evenly distributed to the first and second paging packets.

[0241] For example, the base station supports two paging packets: a first paging packet and a second paging packet, corresponding to two paging packet resources. If there are seven paging packets in total, namely the first paging packet, the second paging packet, ..., the seventh paging packet, then the first to the third paging packets can be mapped to the first paging packet resource, and the remaining four can be mapped to the second paging packet resource. It should be noted that this is not limited to the above equal distribution method; arbitrarily selected paging packets can also be evenly distributed to the first and second paging packets.

[0242] It should be noted that when a base station only supports one paging packet, all paging resources can be allocated to that single paging packet.

[0243] In one embodiment, when the mapping resource cannot be determined according to the mapping relationship information sent by the base station, for example, if the base station supports a number of paging packets for a predetermined method, and the number of paging packets allocated based on the predetermined method is b, where b is greater than a, and the base station only broadcasts a mapping relationships, then there are still (ba) paging packets whose corresponding paging resources cannot be determined. In this case, the paging resources of the remaining (ba) paging packets can be determined based on the pre-configured predetermined mapping relationships.

[0244] For example, if a base station only broadcasts that the number of paging packets supported by the base station is 3, then the broadcast mapping relationship is also 3. However, if the number of packets allocated based on the predetermined method is in the range of 8, then only 3 paging packets can find paging resources based on the mapping relationship, while the other 5 paging packets can determine paging resources using the predetermined mapping relationship.

[0245] As one example, the mapping relationship explicitly indicated by the base station and the mapping relationship agreed upon by the protocol can be used in combination.

[0246] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0247] In one embodiment, the predetermined mapping relationship includes:

[0248] The mapping relationship between paging packets and paging packet resources is determined based on the order of paging packet information and the order of paging packet resources;

[0249] or,

[0250] The mapping relationship between paging packet information and paging packet resources determined according to a random selection method.

[0251] In one embodiment, the paging groups are arranged in the order of Subgroup0, Subgroup1, ...; the paging resources are arranged in the order of radio resource 0, radio resource 1, ...; then Subgroup0 is mapped to radio resource 0; and Subgroup1 is mapped to radio resource 1. Thus, after the terminal determines its paging group, the paging resources mapped to that paging group can be determined based on the information of that paging group.

[0252] Here, the random selection method can be to randomly select paging group resources.

[0253] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0254] like Figure 12 As shown, this embodiment provides a method for group paging, wherein the method is executed by a terminal, and the method includes:

[0255] Step 121: In response to the fact that the number of paging packets allocated based on a predetermined method is greater than the number of paging packets supported by the base station for the predetermined method, determine the paging packet resources used by the terminal for paging based on the paging packet to which the terminal belongs, the mapping relationship indicated by the mapping relationship information, and the predetermined mapping relationship.

[0259] Step 131: In response to the fact that the number of paging packets allocated based on a predetermined method is greater than the number of paging packets supported by the base station for the predetermined method, a paging operation is performed using predetermined paging packet resources, wherein the predetermined paging packet resources are pre-configured;

[0260] or,

[0261] If the number of paging packets allocated based on a predetermined method is greater than the number of paging packets supported by the base station for the predetermined method, the paging operation is not performed using paging packets.

[0262] Here, the reserved paging group resources can be resources indicated by the Lay1subgroup index, which the base station supports for paging group modes used in CN.

[0263] Here, performing a paging operation without using paging groups can mean using public or default paging resources instead of paging groups.
