Description

Technical Field

[0001] This application relates to, but is not limited to, the field of wireless communication technology, and particularly to information transmission methods, apparatus, communication devices, and storage media. Background Technology

[0002] In related technologies, during a paging occupancy (PO), all user equipment (UEs) are woken up to listen for paging messages. The probability of an individual UE being paged within the PO varies. UEs with a lower probability of being paged will be woken up along with UEs with a higher probability of being paged. UEs with a lower probability of being paged are more likely to be falsely woken up, resulting in more false alarms and unnecessary power consumption. Summary of the Invention

[0038] 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 cellular mobile communication technology. The wireless communication system may include: a number of terminals 11 and a number of base stations 12.

[0039] Terminal 11 can be a device that provides voice and / or data connectivity to a user. Terminal 11 can communicate with one or more core networks via a Radio Access Network (RAN). Terminal 11 can be an Internet of Things (IoT) terminal, such as a sensor device, a mobile phone (or "cellular" phone), and a computer with an IoT terminal. 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 (UE). Alternatively, terminal 11 can also be a device in an unmanned aerial vehicle (UAV). Alternatively, terminal 11 can also be a vehicle-mounted device, such as a vehicle computer with wireless communication capabilities, or a wireless communication device connected to an external vehicle computer. Alternatively, terminal 11 can also be a roadside device, such as a street light, traffic light, or other roadside device with wireless communication capabilities.

[0040] Base station 12 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 a 5G NR system. Alternatively, it can be a next-generation system after 5G. In this case, the access network in the 5G system can be called NG-RAN (New Generation-Radio Access Network). Alternatively, it can be an MTC system.

[0041] In this embodiment, base station 12 can be an evolved NB (eNB) used in a 4G system. Alternatively, base station 12 can also be a gNB (gNB) using a centralized-distributed architecture in a 5G system. When base station 12 adopts a centralized-distributed architecture, it typically includes a central unit (CU) and at least two distributed units (DU). The central unit is equipped with a protocol stack of Packet Data Convergence Protocol (PDCP), Radio Link Control (RLC), and Media Access Control (MAC) layers; the distributed units are equipped with a physical (PHY) layer protocol stack. This disclosure does not limit the specific implementation of base station 12.

[0042] Base station 12 and terminal 11 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.

[0043] In some embodiments, terminals 11 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.

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

[0045] Several base stations 12 are connected to network management device 13. Network management device 13 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 13 is not limited in this embodiment.

[0046] The execution entities involved in the embodiments disclosed herein include, but are not limited to: mobile phone terminals in cellular mobile communication systems, network-side equipment such as base stations and other access network equipment, and core networks.

[0047] For scenarios where all UEs will be woken up within the PO, paging packets can be used to address this. Packet information can be carried in the Paging Downlink Control Information (Paging DCI) or the Paging Earlier Indication (PEI). The UE determines whether to wake up within the PO based on the packet information. This packet information can be used to determine the UE's group. For example, packet information may include a group identifier, etc.

[0048] One grouping method is based on UE identification information (UE-ID). Grouping can be determined based on expression (1):

[0049]

[0050] Where wg represents the index of different paging packet resources. 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. Where N represents the paging frame density in the time domain, N s N represents the paging density within a paging frame in the time domain; n N indicates narrowband paging; w This indicates the total number of paging packet resources.

[0051] Another grouping method involves the core network acting as a unified node. In this method, group identifiers (subgroup IDs) are directly assigned in the NR (Network Node Interface). When assigning this subgroup ID, the network will base the allocation on implementation factors, such as terminal attributes or statistical paging probabilities.

[0052] For example, PEI can use 1 bit to wake up all UEs, that is, it can wake up UEs that are not grouped.

[0053] Therefore, how the UE can be woken up based on PEI when two paging grouping methods are used and PEI can wake up non-grouped UEs is an urgent problem to be solved.

[0054] like Figure 2 As shown, this exemplary embodiment provides an information transmission method that can be executed by a base station of a cellular mobile communication system, including:

[0055] Step 201: Receive first capability indication information, wherein the first capability indication information indicates whether the UE supports PEI.

[0056] PEI can be used to instruct the UE to wake up and listen for paging messages within a predetermined paging occasion (PO). Here, the predetermined PO can include one or more POs following the PEI. Whether PEI is supported may include, but is not limited to, whether PEI-based instructions for waking up within a predetermined PO are supported.

[0057] PEI can be used to wake up all UEs, or it can be used to wake up UEs within a predetermined range (such as a predetermined group, predetermined type, etc.). PEI can contain indication information for UEs in different groups, used to wake up UEs in different groups. Whether PEI is supported may include, but is not limited to: whether PEI for waking up all UEs is supported, and / or whether PEI for waking up UEs within a predetermined range is supported.

[0058] Capability indication information can be sent by the UE to the base station, by the core network to the base station, or by the peer base station.

[0059] The UE can carry capability indication information through uplink signaling during random access or after establishing an RRC connection.

[0060] After receiving the capability indication information, the base station can determine whether the UE supports PEI. If the UE supports PEI, the base station uses the UE-supported PEI to wake up the UE and listen to the PO. This reduces situations where the base station cannot determine whether the UE supports PEI, resulting in sending PEI to the UE when the UE does not support it, or not sending PEI to the UE when the UE supports it. Sending PEI to the UE when the UE does not support it increases the base station's workload; while not sending PEI to the UE when the UE supports it results in the UE not receiving the PEI and needs to frequently wake up the listening PO, causing UE power consumption.

[0061] In this way, the capability indication information indicates whether the UE supports PEI. The base station can determine the UE's PEI capability, reducing misjudgments of the UE's capability due to the base station's uncertainty about the UE's PEI capability, and improving the accuracy of the base station's judgment on the UE's PEI capability.

[0062] In one embodiment, the first capability indication information is used to indicate at least one of the following:

[0063] Does the UE support Type I PEI?

[0064] Does the UE support a second type of PEI, wherein the first type of PEI is different from the second type of PEI?

[0065] In one embodiment, the first type of PEI may have one bit for indicating whether the UE is awake. Besides serving as a paging indication, the first type of PEI can also be used to carry other information in subsequent extensions, such as reference signal availability information. In this document, a preferred embodiment of the first type of PEI is used to indicate a non-packet PEI.

[0066] In one embodiment, the second type of PEI may have multiple bits for indicating whether the UE is awake.

[0067] The first type of PEI is a public PEI that can be used to wake up all UEs that need to listen to the same PO;

[0068] The second type of PEI is a PEI for paging groups, which can be used to wake up all UEs listening to the same PO in the paging group according to the paging group.

[0069] When a PEI has 1 bit, meaning it is a Type I PEI, the PEI can be used to wake up all UEs that received that PEI. In other words, Type I PEIs do not distinguish between UE paging packets.

[0070] When a PEI has multiple bits (i.e., it is a Type II PEI), each of these multiple bits can be used to wake up a UE from one or more paging packets. In other words, Type II PEIs distinguish UE paging packets.

[0071] For example, the PEI may include POnumPerPEI segments, which can be referred to as the subgroupsNumPerPO field. Each segment may correspond to a PO. Each segment contains subgroupsNumPerPO bits, and each bit carries a paging indication to indicate whether one or more paging groups have been woken up at the corresponding PO.

[0072] The PEI is a Type 1 PEI. The subgroupsNumPerPO field has a 1-bit paging indicator bit, used to wake up all UEs that received this PEI to listen for paging messages within the PO period. For example, when the paging indicator bit is "1", all UEs that received this PEI are woken up to listen for paging messages within the PO period. When the paging indicator bit is "0", it instructs the UE to remain in a sleep state within the PO period, such as maintaining an RRC idle state or an RRC inactive state.

[0073] The PEI is a type II PEI. The subgroupsNumPerPO field has multiple bits, each corresponding to a paging group. UEs in different paging groups determine whether to wake up within the PO period based on the bits corresponding to their own paging group. For example, the subgroupsNumPerPO field has two bits corresponding to two paging groups respectively. When one bit is "1", the UE in the paging group corresponding to that bit is awakened to listen for paging messages within the PO. When one bit is "0", the UE in the paging group corresponding to that bit is instructed to remain in sleep mode within the PO.

[0074] Capability indication information can be used to indicate whether the UE supports Type I PEI and / or Type II PEI.

[0075] If the capability indication information indicates that the UE supports Type I PEI, then the base station can use Type I PEI to wake up the UE to listen to PO. This reduces the need for the UE to be woken up at every PO, thus reducing the UE's power consumption.

[0076] If the capability indication information indicates that the UE supports Type 2 PEI, then the base station can use Type 2 PEI to wake up the UE to listen to the PO based on the paging packet. This reduces the UE's power consumption when the UE is woken up by the PO if the paging packet to which the UE belongs is not being paged.

[0077] In this way, the capability indication information indicates whether the UE supports PEI. The base station can determine the UE's PEI capability, and then, based on the UE's PEI capability, send the PEI supported by the UE to wake up the UE to listen to PO. When it is not necessary to wake up the UE, the base station will not wake up the UE to listen, thereby reducing the power consumption caused by the frequent UE wake-up.

[0078] In one embodiment, whether the UE supports a second type of PEI includes at least one of the following:

[0079] Does the UE support at least the second type of PEI corresponding to the first type of paging packet mode?

[0080] Does the UE support at least the second type of PEI corresponding to the second type of paging packet mode?

[0081] Type I paging and Type II paging use different methods to divide paging packets. Type I and Type II paging can also be executed by different network nodes, or they can be executed by the same network node.

[0082] The core network or base stations can use different paging packet methods to divide paging packets, thereby generating different types of paging packets. Each paging packet method can divide paging packets into multiple packets. For example, packets can be grouped based on the UE's service type or based on the UE's transmission rate.

[0083] The second type of PEI, which corresponds at least to the first type of paging packet mode, can be used to at least indicate whether the UE corresponding to the paging packet of the first type of paging packet mode is awake.

[0084] The second type PEI, which corresponds at least to the second type of paging packet mode, can be used to at least indicate whether the UE corresponding to the paging packet of the second type of paging packet mode is awake.

[0085] In one embodiment,

[0086] The first type of paging packet method includes: a paging packet method in which the core network determines the paging packet;

[0087] The second type of paging packet method includes: a paging packet method that determines the paging packet based on the UE identifier.

[0088] The first type of paging packet method can be a method in which the core network divides paging packets based on UE attributes. Here, UE attributes may include, but are not limited to: UE service type, UE transmission quantity, UE transmission bandwidth, etc.

[0089] The second type of paging packet method can be that of access network equipment, such as a base station, which divides paging packets based on UE identification information (UE-ID). For example, the base station can use expression (1) to determine the UE's paging packet.

[0090] In the second type of PEI, each bit can be used to indicate whether one or more paging packets have been activated within a predetermined PO. Here, the paging packets can include paging packets classified using the first type of paging packet method, or paging packets classified using the second type of paging packet method.

[0091] For example, the second type of PEI may have 8 bits, wherein each of the 4 bits is used to indicate one of the 4 paging packets divided using the first type of paging packet method, and each of the other 4 bits is used to indicate one of the 4 paging packets divided using the second type of paging packet method.

[0092] The second type of PEI corresponds at least to the first type of paging packet mode, and may include the second type of PEI that corresponds only to the first type of paging packet mode, or the second type of PEI that corresponds to both the first type of paging packet mode and the second type of paging packet mode.

[0093] The second type of PEI corresponds at least to the second type of paging packet mode, and may include the second type of PEI that corresponds only to the second type of paging packet mode, or may include the second type of PEI that corresponds to both the first type of paging packet mode and the second type of paging packet mode.

[0094] The capability indication information indicates whether the UE supports PEIs corresponding to different types of paging packets. The base station can determine the UE's support capability for PEIs corresponding to different paging packet types. Then, the base station can send the UE's corresponding PEI for the paging packet type to wake up the UE to listen to the PO, reducing the chance of the UE being woken up in the PO of other types of paging packets and reducing the power consumption caused by the UE being woken up in invalid POs.

[0095] like Figure 3 As shown in the exemplary embodiment, this method provides an information transmission method, the method further comprising at least one of the following:

[0096] Step 301a: In response to the first capability indication information indicating that the UE supports the second type of PEI, determine that the UE supports the first type of PEI;

[0097] Step 301b: In response to the first capability indication information indicating that the UE does not support the second type of PEI corresponding to at least the first type of paging packet mode and the second type of PEI corresponding to at least the second type of paging packet mode, determine that the UE does not support the first type of PEI.

[0098] Here, steps 301a or 301b can be implemented alone or in combination with step 201.

[0099] Capability indication information can explicitly indicate whether the UE supports PEI and the PEI corresponding to different paging packet directions. Capability indication information can also implicitly indicate whether the UE supports PEI and the PEI corresponding to different paging packet directions.

[0100] For example, when the capability indication information indicates that the UE supports the second type of PEI, then the capability indication information may implicitly indicate that the UE also supports the first type of PEI. Here, the second type of PEI may include: a second type of PEI that corresponds at least to the first type of paging packet mode, and / or a second type of PEI that corresponds at least to the second type of paging packet mode.

[0101] For example, when the capability indication information indicates that the UE does not support the second type of PEI, then the capability indication information implicitly indicates that the UE also does not support the first type of PEI. Here, the second type of PEI may include: a second type of PEI that corresponds at least to the first type of paging packet mode and a second type of PEI that corresponds at least to the second type of paging packet mode.

[0102] Capability indication information can be specified through communication protocols or agreed upon by the core network, base station, and UE using explicit and / or implicit indication methods.

[0103] Capability indication information may be provided in the form of explicit indication and / or implicit indication, and may take one or more of the following forms:

[0104] Method 1: Whether the UE supports Type I PEI and Type II PEI can be indicated separately.

[0105] Capability indication information can be used to individually indicate to the base station that the UE supports Type 1 PEI;

[0106] Capability indication information can individually indicate to the base station that the UE supports at least Type 2 PEI corresponding to Type 2 paging packet mode;

[0107] Method 2: Indicate whether Type I PEI and Type II PEI are supported through a capability indication message.

[0108] The capability indication information indicates that the UE supports Type 2 PEI, while implicitly indicating that the UE supports Type 1 PEI.

[0109] If the UE supports the first type of PEI, it can report capability indication information to indicate support for the second type of PEI, in addition to indicating support for the first type of PEI.

[0110] The UE can report only the capability indication information to indicate support for the first type of PEI, while implicitly indicating that it does not support the second type of PEI.

[0111] The UE can report capability indication information to indicate that it supports both Type I PEI and Type II PEI. The capability indication information can use two flags to indicate that the UE supports Type I PEI and Type II PEI respectively.

[0112] The UE can report capability indication information to indicate that it supports the first type of PEI, but does not support the second type of PEI; it can express that it only supports the first type of PEI by not reporting the flag, that is, by using the default (absence) flag to implicitly express that it does not support the second type of PEI.

[0113] The UE can report capability indication information to indicate support for Type 2 PEI; the implicit meaning of reporting support for Type 2 PEI is that the UE also supports Type 1 PEI.

[0114] The capability indication information reported by the UE indicates whether the UE supports the second type of PEI, and may include an indication of whether the UE supports the second type of PEI corresponding to at least the second type of paging packet mode.

[0115] Method 3: The UE can simply report whether it supports Type 2 PEI to the base station, which corresponds to at least Type 2 paging packet mode.

[0116] The base station can also obtain capability indication information from the core network as to whether the UE supports at least the second type of PEI corresponding to the first type of paging packet mode; that is, the base station obtains whether the UE supports at least the second type of PEI corresponding to the first type of paging packet mode from the core network, and combines the two methods to obtain the UE's capability;

[0117] If the base station determines that the UE supports at least the second type of PEI corresponding to the first type of paging packet mode, or supports at least the second type of PEI corresponding to the second type of paging packet mode, then the base station determines that the UE supports the first type of PEI.

[0118] If the base station determines that the UE does not support the second type of PEI corresponding to at least the first type of paging packet mode, and does not support the second type of PEI corresponding to at least the second type of paging packet mode, then the base station determines that the UE does not support the first type of PEI.

[0119] In one embodiment, receiving the first capability indication information includes at least one of the following:

[0120] Receive the first capability indication information sent by the UE, indicating whether the UE supports the first type of PEI;

[0121] Receive the first capability indication information sent by the UE, indicating whether the UE supports at least the second type of PEI corresponding to the second type of paging packet mode;

[0122] Receive the first capability indication information sent by the core network;

[0123] Receive the first capability indication information sent by the peer base station.

[0124] The UE can determine whether it supports Type 1 PEI. Therefore, the UE can send capability indication information to the base station to indicate whether the UE supports Type 1 PEI.

[0125] The UE can determine whether it supports at least Type 2 PEI corresponding to Type 2 paging packet mode. For example, the UE can determine whether it supports paging packet mode based on UE_ID. Therefore, the UE can send capability indication information to the base station to indicate whether the UE supports at least Type 2 PEI corresponding to Type 2 paging packet mode.

[0126] For example, the base station determines, based on capability indication information reported from the UE, that the terminal supports at least a Type 2 PEI corresponding to a Type 2 paging packet mode. Alternatively, the base station determines, based on capability indication information reported from the UE, that the terminal does not support at least a Type 2 PEI corresponding to a Type 2 paging packet mode. Or, if the base station does not receive capability indication information, it determines that the terminal does not support at least a Type 2 PEI corresponding to a Type 2 paging packet mode.

[0127] In one embodiment, capability indication information may be carried in UE Capability Information or uplink auxiliary messages. UE Capability Information is used to indicate at least the frequencies supported by the UE.

[0128] When a UE is released from RRC connection state, it can carry capability indication information via uplink auxiliary messages.

[0129] Capability indication information can also be sent from the core network to the base station. The capability indication information indicates whether the UE supports Type I PEI and whether the UE supports Type II PEI corresponding to at least Type II paging packet mode.

[0130] Whether a UE supports at least a Type 2 PEI corresponding to a Type 1 paging packet mode can be reported by the UE to the core network via NAS signaling. Therefore, the capability indication information sent by the core network to the base station can also indicate whether the UE supports at least a Type 2 PEI corresponding to a Type 1 paging packet mode.

[0131] For example, whether a terminal supports at least the second type of PEI corresponding to the first type of paging packet mode is determined by the base station through a display indication based on the capability indication information sent by the core network.

[0132] The capabilities of the UE can also be transmitted between base stations. Capability indication information can be sent by the peer base station.

[0133] For example, the UE can be an inactive UE, and the peer base station can be the anchor base station of the UE. The anchor base station retains capability indication information of whether the UE supports PEI. When the UE performs cell reselection within the coverage area of ​​the current base station, the current base station can obtain capability indication information from the anchor base station to determine whether the UE supports PEI.

[0134] For example, when a cell reselection occurs in an inactive UE, the base station obtains the terminal's reporting capability from the anchor base station.

[0135] For example, capability indication information can be sent to the base station in the UE context response. Capability indication information can also be sent to the base station in a paging message from the core network.

[0136] The base station can directly determine whether the UE supports Type I PEI based on the capability indication information sent by the peer base station;

[0137] Based on the capability indication information sent by the peer base station, the base station can directly determine whether the UE supports at least Type 2 PEI corresponding to Type 1 paging packet mode;

[0138] Based on the capability indication information sent by the peer base station, the base station can directly determine whether the UE supports at least Type II PEI corresponding to Type II paging packet mode;

[0139] The base station determines that the UE supports the first type of PEI based on the UE supporting at least the second type of PEI corresponding to the first type of paging packet mode, or the UE supporting at least the second type of PEI corresponding to the second type of paging packet mode.

[0140] The base station determines that the UE does not support the first type of PEI based on the fact that the UE does not support the second type of PEI corresponding to at least the first type of paging packet mode, or the UE does not support the second type of PEI corresponding to at least the second type of paging packet mode.

[0141] In one embodiment, in response to the peer base station sending packet information of the UE's first type of paging packet mode, it is determined that the UE supports a second type of PEI that corresponds to at least the first type of paging packet mode.

[0142] In one embodiment, receiving the first capability indication information sent by the core network includes:

[0143] In response to receiving packet information of the first type of paging packet mode of the UE sent by the core network, it is determined that the UE supports at least the second type of PEI corresponding to the first type of paging packet mode.

[0144] The first capability indication information can be the packet information of the UE's first type paging packet mode. When the core network sends the UE's first type paging packet mode packet information to the base station, it can be determined that the UE supports at least the second type PEI corresponding to the first type paging packet mode.

[0145] Packet information can be used to indicate paging packets. Packet information can be the UE's subgroup ID. If the core network has assigned a subgroup ID to the UE, it can be determined that the terminal supports at least the second type of PEI corresponding to the first type of paging packet mode. The packet information sent by the core network can be considered an implicit expression that the terminal supports at least the second type of PEI corresponding to the first type of paging packet mode.

[0146] For example, the terminal supports at least the second type of PEI corresponding to the first type of paging group mode, which is determined by the base station based on the group identifier sent by the core network.

[0147] like Figure 4 As shown in the exemplary embodiment, this method provides an information transmission method, the method further comprising at least one of the following:

[0148] Step 401a: Send second capability indication information to the peer base station, indicating whether the UE supports the first type of PEI;

[0149] Step 401b: Send second capability indication information to the peer base station, indicating whether the UE supports the second type of PE;

[0150] Step 401c: Send second capability indication information to the core network indicating whether the UE supports the first type of PEI;

[0151] Step 401d: Send to the core network a second capability indication message indicating whether the UE supports at least the second type of PE corresponding to the second type of paging packet mode.

[0152] Here, steps 401a, 401b, 401c and / or step 401d can be implemented individually or in combination with steps 301a, 301b and / or step 201.

[0153] The capabilities of a UE can also be transmitted between base stations. A base station can send capability indication information to the peer base station.

[0154] For example, the UE can be an inactive UE, the peer base station can be the base station where the UE performs cell reselection, and the anchor base station retains capability indication information on whether the UE supports PEI. When the UE performs cell reselection within the coverage area of ​​the peer base station, the anchor base station can send capability indication information to the peer base station, and the peer base station can determine whether the UE supports PEI.

[0155] The capability indication information transmitted between base stations can indicate at least one of the following: whether the UE supports Type I PEI; whether the UE supports Type II PEI.

[0156] After receiving the capability indication information reported by the UE, the base station can report the UE's capabilities to the core network. The capability indication information reported by the UE can indicate whether the UE supports Type I PEI and / or whether the UE supports Type II PEI corresponding to at least Type II paging packet mode. Therefore, the capability indication information sent by the base station can also indicate whether the UE supports Type I PEI and / or whether the UE supports at least Type II PEI corresponding to at least Type II paging packet mode.

[0157] For example, the UE reports its PEI support capability to the base station via capability indication information, and the base station then notifies the core network via capability indication information. The capability indication information can indicate whether the UE supports Type I PEI, and / or whether the UE supports Type II PEI corresponding to at least Type II paging packet mode. Whether the UE supports Type II PEI corresponding to at least Type I paging packet mode is transmitted by the terminal to the core network via NAS signaling; therefore, the base station does not need to report it.

[0158] For example, capability indication information can be carried in the following message:

[0159] UE CAPABILITY INFORMATION;

[0160] RRC INACTIVE TRANSITION REPORT.

[0161] In one embodiment, the base station sends the PEI supported by the UE to the UE.

[0162] Once the base station determines the PEIs that the UE can support, it can send those PEIs to the UE during subsequent paging processes. In this way, the base station can send the UE-supported PEIs to wake the UE up to listen for the PO, and avoid waking the UE for listening when it is not necessary, thus reducing power consumption caused by frequent UE wake-ups.

[0163] like Figure 5 As shown in the exemplary embodiment, this method provides an information transmission method, the method further comprising:

[0164] Step 501: Send third capability indication information to the UE, wherein the third capability indication information is used to enable the UE to determine the PEI that the base station can send.

[0165] Here, step 501 can be implemented alone or in combination with steps 301a, 301b, 401a, 401b, 401c, 401d and / or step 201.

[0166] Capability indication information can indicate the PEIs that the base station can transmit. The UE can determine whether to listen to the PEIs transmitted by the base station based on the PEIs that the base station can transmit and the PEIs that the UE itself supports.

[0167] For example, if the UE can support the PEI transmitted by the base station, then the UE can listen to the PEI. If the UE does not support the PEI transmitted by the base station, then the UE can choose not to listen to the PEI transmitted by the base station.

[0168] If the UE does not listen to the base station's PEI, then the UE can wake up at each PO and listen to paging messages.

[0169] Capability indication information can be carried in public signaling. For example, capability indication information can be carried in system messages and broadcast to the UE.

[0170] Capability indication information can be carried in dedicated signaling. For example, capability indication information can be sent to the UE in an RRC message.

[0171] In one embodiment, the third capability indication information is used to enable the UE to determine that the base station is capable of transmitting at least one of the following:

[0172] The first type of PEI;

[0173] The second type of PEI corresponding to the first type of paging packet method includes multiple bits;

[0174] The second type of PEI corresponds to the second type of paging grouping method;

[0175] The second type of PEI corresponding to the first type of paging packet method and the second type of paging packet method.

[0176] For example, if the base station is able to send a Type I PEI, then a UE that supports Type I PEI can listen to the PEI and listen to paging messages based on the indication of the PEI.

[0177] For example, if the base station can send a Type I PEI, then a UE that does not support Type I PEI can stop listening to the PEI and fall back to the legacy paging method, listening for paging messages at each PO wake-up.

[0178] For example, if the base station can send the second type PEI corresponding to the first type paging packet method, then the UE that supports the second type PEI corresponding to the first type paging packet method can listen to the PEI and listen to paging messages based on the indication of the PEI.

[0179] In one embodiment, the UE determines whether it needs to be woken up by the PO based on its own first type of paging packet information and the indication of the PEI.

[0180] For example, PEI can indicate which packets need to be woken up in the first type of paging packet mode, and the UE can determine whether its own packets need to be woken up.

[0181] For example, if the base station can send the second type PEI corresponding to the first type paging group, then the base station that does not support the second type PEI corresponding to the first type paging group can stop listening to the PEI and fall back to the legacy paging method, listening to the paging message at each PO wake-up.

[0182] In one embodiment, if the base station can send the second type of PEI corresponding to the first type of paging packet mode, the UE that supports the second type of PEI corresponding to the first type of paging packet mode can listen to the PEI sent by the base station only when it is configured with the packet information of the first type of paging packet mode; otherwise, the UE does not listen to the PEI.

[0183] For example, if the base station can send the second type PEI corresponding to the second paging packet method, then the UE that supports the second type PEI corresponding to the second type paging packet method can listen to the PEI and listen to paging messages based on the indication of the PEI.

[0184] For example, if the base station can send the second type PEI corresponding to the second type paging group method, then if it does not support the second type PEI corresponding to the second type paging group method, it can stop listening to the PEI and fall back to the legacy paging method, listening to the paging message at each PO wake-up.

[0185] For example, the base station can send a second type PEI corresponding to the first type paging packet mode and the second paging packet mode. If the UE supports a second type PEI corresponding to at least the first type paging packet mode, or supports a second type PEI corresponding to at least the second type paging packet mode, then the UE can listen to the PEI and listen to paging messages based on the indication of the PEI.

[0186] For example, the base station can send a second type PEI corresponding to the first type paging packet mode and the second paging packet mode. If the UE does not support the second type PEI corresponding to at least the first type paging packet mode, nor does it support the second type PEI corresponding to at least the second type paging packet mode, then the UE can not listen to the PEI and fall back to the legacy paging mode, listening to the paging message at each PO wake-up.

[0187] In one embodiment, if the base station can send the second type of PEI corresponding to the first type of paging packet mode and the second type of paging packet mode, the UE that only supports the second type of PEI corresponding to the first type of paging packet mode can listen to the PEI sent by the base station when the packet information of the first type of paging packet mode is configured; otherwise, the UE does not listen to the PEI.

[0188] In one embodiment, if the base station can send a second type of PEI corresponding to both the first and second paging packet modes, and the UE supports at least one second type of PEI corresponding to the first paging packet mode and at least one second type of PEI corresponding to the second paging packet mode, the UE can listen to the PEI sent by the base station and detect the PEI using the packet information of the UE's first and second paging packet modes respectively, to determine whether the packet corresponding to the packet information of the first or second paging packet mode should be used for PO wake-up. Here, the packet information of the UE's first paging packet mode can be a group identifier allocated by the core network, or the packet information of the UE's first paging packet mode can be a group identifier determined based on the UE_ID.

[0189] like Figure 6 As shown, this exemplary embodiment provides an information transmission method that can be executed by a UE of a cellular mobile communication system, including:

[0190] Step 601: Send first capability indication information, wherein the first capability indication information indicates whether the UE supports PEI.

[0191] PEI can be used to instruct the UE to wake up and listen for paging messages within a predetermined paging occasion (PO). Here, the predetermined PO can include one or more POs following the PEI. Whether PEI is supported may include, but is not limited to, whether PEI-based instructions for waking up within a predetermined PO are supported.

[0192] PEI can be used to wake up all UEs, or it can be used to wake up UEs within a predetermined range (such as a predetermined group, predetermined type, etc.). PEI can contain indication information for UEs in different groups, used to wake up UEs in different groups. Whether PEI is supported may include, but is not limited to: whether PEI for waking up all UEs is supported, and / or whether PEI for waking up UEs within a predetermined range is supported.

[0193] The UE can carry capability indication information via uplink signaling during random access or after establishing an RRC connection. The UE can also carry capability indication information via NAS signaling.

[0194] Capability indication information can be received by base stations or core networks.

[0195] After receiving the capability indication information, the base station can determine whether the UE supports PEI. If the UE supports PEI, the base station uses the UE-supported PEI to wake up the UE and listen to the PO. This reduces situations where the base station cannot determine whether the UE supports PEI, resulting in sending PEI to the UE when the UE does not support it, or not sending PEI to the UE when the UE supports it. Sending PEI to the UE when the UE does not support it increases the base station's workload; while not sending PEI to the UE when the UE supports it results in the UE not receiving the PEI and needs to frequently wake up the listening PO, causing UE power consumption.

[0196] In this way, the capability indication information indicates whether the UE supports PEI. The base station can determine the UE's PEI capability, reducing misjudgments of the UE's capability due to the base station's uncertainty about the UE's PEI capability, and improving the accuracy of the base station's judgment on the UE's PEI capability.

[0197] In one embodiment, the first capability indication information is used to indicate at least one of the following:

[0198] Does the UE support Type I PEI?

[0199] Does the UE support the second type of PEI, wherein the first type of PEI is different from the second type of PEI?

[0200] The first type of PEI can have 1 bit to indicate whether the UE is awake. The second type of PEI can have multiple bits to indicate whether the UE is awake.

[0201] The first type of PEI is a public PEI that can be used to wake up all UEs that need to listen to the same PO;

[0202] The second type of PEI is a PEI for paging groups, which can be used to wake up all UEs listening to the same PO in the paging group according to the paging group.

[0203] When a PEI has 1 bit, meaning it is a Type I PEI, the PEI can be used to wake up all UEs that received that PEI. In other words, Type I PEIs do not distinguish between UE paging packets.

[0204] When a PEI has multiple bits (i.e., it is a Type II PEI), each of these multiple bits can be used to wake up a UE from one or more paging packets. In other words, Type II PEIs distinguish UE paging packets.

[0205] For example, the PEI may include POnumPerPEI segments, which can be referred to as the subgroupsNumPerPO field. Each segment may correspond to a PO. Each segment contains subgroupsNumPerPO bits, and each bit carries a paging indication to indicate whether one or more paging groups have been woken up at the corresponding PO.

[0206] The PEI is a Type 1 PEI. The subgroupsNumPerPO field has a 1-bit paging indicator bit, used to wake up all UEs that received this PEI to listen for paging messages within the PO period. For example, when this paging indicator bit field is "1", it wakes up all UEs that received this PEI to listen for paging messages within the PO period. When this paging indicator bit field is "0", it instructs the UE to remain in a sleep state within the PO period, such as maintaining an RRC idle state or an RRC inactive state.

[0207] The PEI is a type II PEI. The subgroupsNumPerPO field has multiple bits, each corresponding to a paging group. UEs in different paging groups determine whether to wake up within the PO period based on the bits corresponding to their own paging group. For example, the subgroupsNumPerPO field has two bits corresponding to two paging groups respectively. When one bit is "1", the UE in the paging group corresponding to that bit is awakened to listen for paging messages within the PO. When one bit is "0", the UE in the paging group corresponding to that bit is instructed to remain in sleep mode within the PO.

[0208] Capability indication information can be used to indicate whether the UE supports Type I PEI and / or Type II PEI.

[0209] If the capability indication information indicates that the UE supports Type I PEI, then the base station can use Type I PEI to wake up the UE to listen to PO. This reduces the need for the UE to be woken up at every PO, thus reducing the UE's power consumption.

[0210] If the capability indication information indicates that the UE supports Type 2 PEI, then the base station can use Type 2 PEI to wake up the UE to listen to the PO based on the paging packet. This reduces the UE's power consumption when the UE is woken up by the PO if the paging packet to which the UE belongs is not being paged.

[0211] In this way, the capability indication information indicates whether the UE supports PEI. The base station can determine the UE's PEI capability, and then, based on the UE's PEI capability, send the PEI supported by the UE to wake up the UE to listen to PO. When it is not necessary to wake up the UE, the base station will not wake up the UE to listen, thereby reducing the power consumption caused by the frequent UE wake-up.

[0212] In one embodiment, whether the UE supports a second type of PEI includes at least one of the following:

[0213] Does the UE support at least the second type of PEI corresponding to the first type of paging packet mode?

[0214] Does the UE support at least the second type of PEI corresponding to the second type of paging packet mode?

[0215] Type I paging and Type II paging use different methods to divide paging packets. Type I and Type II paging can also be executed by different network nodes, or they can be executed by the same network node.

[0216] The core network or base stations can use different paging packet methods to divide paging packets, thereby generating different types of paging packets. Each paging packet method can divide paging packets into multiple packets. For example, packets can be grouped based on the UE's service type or based on the UE's transmission rate.

[0217] The second type of PEI, which corresponds at least to the first type of paging packet mode, can be used to at least indicate whether the UE corresponding to the paging packet of the first type of paging packet mode is awake.

[0218] The second type PEI, which corresponds at least to the second type of paging packet mode, can be used to at least indicate whether the UE corresponding to the paging packet of the second type of paging packet mode is awake.

[0219] In one embodiment, the first type of paging packet method includes: a paging packet method determined by the core network;

[0220] The second type of paging packet method includes: a paging packet method that determines the paging packet based on the UE identifier.

[0221] The first type of paging packet method can be a method in which the core network divides paging packets based on UE attributes. Here, UE attributes may include, but are not limited to: UE service type, UE transmission quantity, UE transmission bandwidth, etc.

[0222] The second type of paging packet method can be a method in which the base station divides paging packets based on the UE identification information (UE-ID). For example, the base station can use expression (1) to determine the UE's paging packets.

[0223] In the second type of PEI, each bit can be used to indicate whether one or more paging packets have been activated within a predetermined PO. Here, the paging packets can include paging packets classified using the first type of paging packet method, or paging packets classified using the second type of paging packet method.

[0224] For example, the second type of PEI may have 8 bits, wherein each of the 4 bits is used to indicate one of the 4 paging packets divided using the first type of paging packet method, and each of the other 4 bits is used to indicate one of the 4 paging packets divided using the second type of paging packet method.

[0225] The second type of PEI corresponds at least to the first type of paging packet mode, and may include the second type of PEI that corresponds only to the first type of paging packet mode, or the second type of PEI that corresponds to both the first type of paging packet mode and the second type of paging packet mode.

[0226] The second type of PEI corresponds at least to the second type of paging packet mode, and may include the second type of PEI that corresponds only to the second type of paging packet mode, or may include the second type of PEI that corresponds to both the first type of paging packet mode and the second type of paging packet mode.

[0227] The capability indication information indicates whether the UE supports PEIs corresponding to different types of paging packets. The base station can determine the UE's support capability for PEIs corresponding to different paging packet types. Then, the base station can send the UE's corresponding PEI for the paging packet type to wake up the UE to listen to the PO, reducing the chance of the UE being woken up in the PO of other types of paging packets and reducing the power consumption caused by the UE being woken up in invalid POs.

[0228] In one embodiment, sending the first capability indication information includes at least one of the following:

[0229] Send to the base station the first capability indication information indicating whether the UE supports the first type of PEI;

[0230] Send to the base station the first capability indication information indicating whether the UE supports at least the second type of PEI corresponding to the second type of paging packet mode;

[0231] Send to the core network the first capability indication information indicating whether the UE supports at least the second type of PEI corresponding to the first type of paging packet mode.

[0232] The UE can determine whether it supports Type 1 PEI. Therefore, the UE can send capability indication information to the base station to indicate whether the UE supports Type 1 PEI.

[0233] The UE can determine whether it supports at least Type 2 PEI corresponding to Type 2 paging packet mode. For example, the UE can determine whether it supports paging packet mode based on UE_ID. Therefore, the UE can send capability indication information to the base station to indicate whether the UE supports at least Type 2 PEI corresponding to Type 2 paging packet mode.

[0234] For example, the base station determines, based on capability indication information reported from the UE, that the terminal supports at least a Type 2 PEI corresponding to a Type 2 paging packet mode. Alternatively, the base station determines, based on capability indication information reported from the UE, that the terminal does not support at least a Type 2 PEI corresponding to a Type 2 paging packet mode. Or, if the base station does not receive capability indication information, it determines that the terminal does not support at least a Type 2 PEI corresponding to a Type 2 paging packet mode.

[0235] In one embodiment, capability indication information may be carried in UE Capability Information or uplink auxiliary messages. UE Capability Information is used to indicate at least the frequencies supported by the UE.

[0236] When a UE is released from RRC connection state, it can carry capability indication information via uplink auxiliary messages.

[0237] Whether a UE supports at least a Type 2 PEI corresponding to a Type 1 paging packet mode can be reported by the UE to the core network via NAS signaling. Therefore, the capability indication information sent by the core network to the base station can also indicate whether the UE supports at least a Type 2 PEI corresponding to a Type 1 paging packet mode.

[0238] For example, whether a terminal supports at least the second type of PEI corresponding to the first type of paging packet mode is determined by the base station through a display indication based on the capability indication information sent by the core network.

[0239] like Figure 7 As shown in the exemplary embodiment, this method provides an information transmission method, the method further comprising:

[0240] Step 701: Receive second capability indication information from the base station, wherein the second capability indication information is used for the UE to determine the PEI that the base station can transmit.

[0241] Here, step 701 can be implemented alone or in combination with step 601.

[0242] Capability indication information can indicate the PEIs that the base station can transmit. The UE can determine whether to listen to the PEIs transmitted by the base station based on the PEIs that the base station can transmit and the PEIs that the UE itself supports.

[0243] For example, if the UE can support the PEI transmitted by the base station, then the UE can listen to the PEI. If the UE does not support the PEI transmitted by the base station, then the UE can choose not to listen to the PEI transmitted by the base station.

[0244] If the UE does not listen to the base station's PEI, then the UE can wake up at each PO and listen to paging messages.

[0245] Capability indication information can be carried in public signaling. For example, capability indication information can be carried in system messages and broadcast to the UE.

[0246] Capability indication information can be carried in dedicated signaling. For example, capability indication information can be sent to the UE in an RRC message.

[0247] In one embodiment, the second capability indication information is used to enable the UE to determine that the base station is capable of transmitting at least one of the following:

[0248] Type I PEI;

[0249] The second type of PEI corresponds to the first type of paging grouping method, wherein the first type of PEI is different from the second type of PEI;

[0250] The second type of PEI corresponds to the second type of paging grouping method;

[0251] The second type of PEI corresponding to the first type of paging packet method and the second type of paging packet method.

[0252] like Figure 8 As shown in the exemplary embodiment, this method provides an information transmission method, the method further comprising:

[0253] Step 801: Determine whether to listen to the PEI sent by the base station based on the PEI supported by the UE.

[0254] Here, step 801 can be implemented alone or in combination with step 601 and / or step 701.

[0255] The UE can determine whether to listen to the PEI sent by the base station based on its own capabilities. If it does not listen to the PEI, it can adopt relevant technical solutions to listen for paging messages within each PO.

[0256] In one embodiment, determining whether to listen to the PEI sent by the base station based on the PEI supported by the UE includes at least one of the following:

[0257] In response to determining that the UE supports the PEI that the base station can transmit, listen to the PEI transmitted by the base station;

[0258] The response determines that the UE does not support the PEI that the base station can send, and therefore does not listen to the PEI sent by the base station.

[0259] If the UE supports the PEI transmitted by the base station, then the UE can listen to the PEI and wake up within the PO based on the PEI indication. This reduces the need to wake up at every PO, saving UE power consumption.

[0260] If the UE does not support the PEI sent by the base station, then the UE uses relevant techniques to wake up at each PO to listen for paging messages, reducing the chance of missing paging messages.

[0261] In one embodiment, the response determines that the UE supports PEIs that the base station can transmit, and listens for PEIs transmitted by the base station, including at least one of the following:

[0262] In response to the base station being able to transmit a first type of PEI and the UE supporting the first type of PEI, the UE listens to the PEI transmitted by the base station;

[0263] In response to the base station being able to transmit a second type of PEI and the UE supporting the second type of PEI, the UE listens to the PEI transmitted by the base station.

[0264] For example, if the base station is able to send a Type I PEI, then a UE that supports Type I PEI can listen to the PEI and listen to paging messages based on the indication of the PEI.

[0265] For example, if the base station can send a Type I PEI, then a UE that does not support Type I PEI can stop listening to the PEI and fall back to the legacy paging method, listening for paging messages at each PO wake-up.

[0266] For example, if the base station is able to send a Type 2 PEI, then a UE that supports Type 2 PEI can listen to the PEI and listen to paging messages based on the indication of the PEI.

[0267] For example, if the base station can send a Type 2 PEI, then a UE that does not support a Type 2 PEI can stop listening to the PEI and fall back to the legacy paging method, listening for paging messages at each PO wake-up.

[0268] In one embodiment, the UE determines whether it needs to be woken up by the PO based on its own first-type paging packet information and / or second-type paging packet information, as well as the indication of the PEI.

[0269] For example, PEI can at least indicate the paging packet of the first type of paging packet mode that needs to be woken up, and UE can determine whether its own paging packet of the first type of paging packet mode needs to be woken up.

[0270] or,

[0271] PEI can at least indicate the paging packet of the second type of paging packet mode that needs to be woken up, and the UE can determine whether its own paging packet of the second type of paging packet mode needs to be woken up.

[0272] In one embodiment, the step of listening to the PEIs transmitted by the base station in response to the base station being able to transmit the first type of PEI and the UE supporting the first type of PEI includes at least one of the following:

[0273] In response to the base station being able to transmit the first type of PEI, and the UE supporting both the first type of PEI and the second type of PEI, the UE listens to the PEI transmitted by the base station;

[0274] In response to the base station being able to transmit the first type of PEI and the UE supporting the second type of PEI, the UE listens for the PEI transmitted by the base station.

[0275] Capability indication information that indicates UE capabilities can explicitly indicate whether the UE supports PEI and the PEI corresponding to different paging packet directions.

[0276] The capability indication information indicating the UE's capabilities indicates that the UE supports both Type I PEI and Type II PEI. Therefore, when the base station is able to send Type I PEI, the UE can listen to the PEI sent by the base station.

[0277] The capability indication information indicating the UE's capabilities indicates that the UE supports Type II PEIs, and may implicitly indicate that the UE also supports Type I PEIs. In this case, if the base station supports Type I PEIs, then the UE can listen to the PEIs sent by the base station.

[0278] In one embodiment, the step of listening to the PEI transmitted by the base station in response to the base station being able to transmit the second type of PEI and the UE supporting the second type of PEI includes at least one of the following:

[0279] In response to the base station being able to transmit at least the second type PEI corresponding to the first type paging packet mode, the UE supports the second type PEI corresponding to at least the first type paging packet mode and listens to the PEI transmitted by the base station;

[0280] In response to the base station being able to transmit at least a second type of PEI corresponding to a second type of paging packet mode, the UE supports the second type of PEI corresponding to at least a second type of paging packet mode and listens to the PEI transmitted by the base station.

[0281] For example, if the base station can send the second type PEI corresponding to the first type paging packet method, then the UE that supports the second type PEI corresponding to the first type paging packet method can listen to the PEI and listen to paging messages based on the indication of the PEI.

[0282] For example, if the base station can send the second type PEI corresponding to the first type paging group, then the base station that does not support the second type PEI corresponding to the first type paging group can stop listening to the PEI and fall back to the legacy paging method, listening to the paging message at each PO wake-up.

[0283] For example, if the base station can send the second type PEI corresponding to the second paging packet method, then the UE that supports the second type PEI corresponding to the second type paging packet method can listen to the PEI and listen to paging messages based on the indication of the PEI.

[0284] For example, if the base station can send the second type PEI corresponding to the second type paging group method, then if it does not support the second type PEI corresponding to the second type paging group method, it can stop listening to the PEI and fall back to the legacy paging method, listening to the paging message at each PO wake-up.

[0285] For example, the base station can send a second type PEI corresponding to the first type paging packet mode and the second paging packet mode. If the UE supports at least a second type PE corresponding to the first type paging packet mode, or supports at least a second type PE corresponding to the second type paging packet mode, then the UE can listen to the PEI and listen to paging messages based on the indication of the PEI.

[0286] For example, the base station can send a second type PEI corresponding to the first type paging packet mode and the second paging packet mode. If the UE does not support the second type PE corresponding to at least the first type paging packet mode, nor does it support the second type PE corresponding to at least the second type paging packet mode, then the UE can not listen to the PEI and fall back to the legacy paging mode, listening to the paging message at each PO wake-up.

[0287] In one embodiment, the step of responding to the base station being able to transmit at least a second type of PEI corresponding to the first type of paging packet mode, and the UE supporting at least a second type of PEI corresponding to the first type of paging packet mode, and listening to the PEI transmitted by the base station, includes:

[0288] In response to the base station being able to send at least the second type PEI corresponding to the first type paging packet mode, and the UE having packet information of the first type paging packet mode, the UE listens to the PEI sent by the base station.

[0289] For example, if the base station can send the second type of PEI corresponding to the first type of paging packet mode, the UE that supports the second type of PEI corresponding to the first type of paging packet mode can listen to the PEI sent by the base station only when it is configured with the packet information of the first type of paging packet mode; otherwise, the UE does not listen to the PEI.

[0290] For example, if the base station can send the second type of PEI corresponding to the first type of paging packet mode and the second type of paging packet mode, the UE that only supports the second type of PEI corresponding to the first type of paging packet mode can listen to the PEI sent by the base station when it is configured with the packet information of the first type of paging packet mode; otherwise, the UE does not listen to the PEI.

[0291] For example, if the base station can send a second type of PEI corresponding to both the first and second type of paging packet methods, and the UE supports at least one second type of PEI corresponding to the first type of paging packet method and at least one second type of PEI corresponding to the second type of paging packet method, the UE can listen to the PEI sent by the base station and detect the PEI using the packet information of the UE's first type of paging packet method and the packet information of the second type of paging packet method, respectively, to determine whether the packet corresponding to the packet information of the first type of paging packet method or the paging packet corresponding to the packet information of the second type of paging packet method should be used for PO wake-up. Here, the packet information of the UE's first type of paging packet method can be a group identifier allocated by the core network, and the packet information of the UE's first type of paging packet method can be a group identifier determined based on the UE_ID.

[0292] like Figure 9As shown, this exemplary embodiment provides an information transmission method that can be executed by the core network of a cellular mobile communication system, including:

[0293] Step 901: Receive first capability indication information, wherein the first capability indication information indicates whether the UE supports PEI.

[0294] PEI can be used to instruct the UE to wake up and listen for paging messages within a predetermined paging occasion (PO). Here, the predetermined PO can include one or more POs following the PEI. Whether PEI is supported may include, but is not limited to, whether PEI-based instructions for waking up within a predetermined PO are supported.

[0295] PEI can be used to wake up all UEs, or it can be used to wake up UEs within a predetermined range (such as a predetermined group, predetermined type, etc.). PEI can contain indication information for UEs in different groups, used to wake up UEs in different groups. Whether PEI is supported may include, but is not limited to: whether PEI for waking up all UEs is supported, and / or whether PEI for waking up UEs within a predetermined range is supported.

[0296] In addition to carrying paging information, PEI can also be used as an extension to carry other information.

[0297] Capability indication information can be reported by the base station to the core network or sent by the UE to the core network. The UE can also carry capability indication information through NAS signaling, etc.

[0298] After receiving the capability indication information, the core network can determine whether the UE supports PEI. If the UE supports PEI, the core network uses the UE-supported PEI to wake up the UE and listen to the PO. This reduces situations where the core network cannot determine whether the UE supports PEI, resulting in sending PEI to the UE when the UE does not support it, or not sending PEI to the UE when the UE supports it. Sending PEI to the UE when the UE does not support it increases the workload of the core network; while not sending PEI to the UE when the UE supports it results in the UE not receiving the PEI and needs to frequently wake up the listening PO, causing UE power consumption.

[0299] In this way, the capability indication information indicates whether the UE supports PEI. The core network can determine the UE's PEI capability, reducing misjudgments of the UE's capability due to the core network's uncertainty about the UE's PEI capability, and improving the accuracy of the core network's judgment on the UE's PEI capability.

[0300] In one embodiment, the first capability indication information is used to indicate at least one of the following:

[0301] Does the UE support Type I PEI?

[0302] Does the UE support the second type of PEI, wherein the first type of PEI is different from the second type of PEI?

[0303] The first type of PEI can have 1 bit to indicate whether the UE is awake, that is, a PEI that does not carry a paging packet.

[0304] The first type of PEI can also be further extended for uses other than paging.

[0305] In summary, the first type of PEI is supported, meaning that the terminal has the ability to listen for PEI signals, which can carry paging information or other information.

[0306] The second type of PEI can have multiple bits used to indicate whether the UE is awake, i.e., paging packet PEI.

[0307] The second type of PEI can be a subset of the first type of PEI.

[0308] In one embodiment, the first type of PEI is a public PEI or a non-group PEI, which can be used to wake up all UEs or all groups of UEs that need to listen to the same PO;

[0309] In one embodiment, the second type of PEI is a PEI for paging groups, which can be used to wake up all UEs listening to the same PO in the paging group according to the paging group.

[0310] When a PEI has 1 bit, meaning it is a Type I PEI, the PEI can be used to wake up all UEs that received that PEI. In other words, Type I PEIs do not distinguish between UE paging packets.

[0311] When a PEI has multiple bits (i.e., it is a Type II PEI), each of these multiple bits can be used to wake up a UE from one or more paging packets. In other words, Type II PEIs distinguish UE paging packets.

[0312] For example, the PEI may include POnumPerPEI segments, which can be referred to as the subgroupsNumPerPO field. Each segment may correspond to a PO. Each segment contains subgroupsNumPerPO bits, and each bit carries a paging indication to indicate whether one or more paging groups have been woken up at the corresponding PO.

[0313] The PEI is a Type 1 PEI. The subgroupsNumPerPO field has a 1-bit paging indicator bit, used to wake up all UEs that received this PEI to listen for paging messages within the PO period. For example, when the paging indicator bit is "1", all UEs that received this PEI are woken up to listen for paging messages within the PO period. When the paging indicator bit field is "0", it instructs the UE to remain in a sleep state within the PO period, such as remaining in an RRC idle state or an RRC inactive state.

[0314] The PEI is a type II PEI. The subgroupsNumPerPO field has multiple bits, each corresponding to a paging group. UEs in different paging groups determine whether to wake up within the PO period based on the bits corresponding to their own paging group. For example, the subgroupsNumPerPO field has two bits corresponding to two paging groups respectively. When one bit is "1", the UE in the paging group corresponding to that bit is awakened to listen for paging messages within the PO. When one bit is "0", the UE in the paging group corresponding to that bit is instructed to remain in sleep mode within the PO.

[0315] Capability indication information can be used to indicate whether the UE supports Type I PEI and / or Type II PEI.

[0316] If the capability indication information indicates that the UE supports Type I PEI, then the base station can use Type I PEI to wake up the UE to listen to PO. This reduces the need for the UE to be woken up at every PO, thus reducing the UE's power consumption.

[0317] If the capability indication information indicates that the UE supports Type 2 PEI, then the base station can use Type 2 PEI to wake up the UE to listen to the PO based on the paging packet. This reduces the UE's power consumption when the UE is woken up by the PO if the paging packet to which the UE belongs is not being paged.

[0318] In this way, the capability indication information indicates whether the UE supports PEI. The base station can determine the UE's PEI capability, and then, based on the UE's PEI capability, send the PEI supported by the UE to wake up the UE to listen to PO. When it is not necessary to wake up the UE, the base station will not wake up the UE to listen, thereby reducing the power consumption caused by the frequent UE wake-up.

[0319] In one embodiment, whether the UE supports Type II PEI includes at least one of the following:

[0320] Does the UE support at least the second type of PEI corresponding to the first type of paging packet mode?

[0321] Does the UE support at least the second type of PEI corresponding to the second type of paging packet mode?

[0322] Type I paging and Type II paging use different methods to divide paging packets. Type I and Type II paging can also be executed by different network nodes, or they can be executed by the same network node.

[0323] The core network or base stations can use different paging packet methods to divide paging packets, thereby generating different types of paging packets. Each paging packet method can divide paging packets into multiple packets. For example, packets can be grouped based on the UE's service type or based on the UE's transmission rate.

[0324] The second type of PEI, which corresponds at least to the first type of paging packet mode, can be used to at least indicate whether the UE corresponding to the paging packet of the first type of paging packet mode is awake.

[0325] The second type PEI, which corresponds at least to the second type of paging packet mode, can be used to at least indicate whether the UE corresponding to the paging packet of the second type of paging packet mode is awake.

[0326] In one embodiment, the first type of paging packet method includes: a paging packet method determined by the core network;

[0327] The second type of paging packet method includes: a paging packet method that determines the paging packet based on the UE identifier.

[0328] The first type of paging packet method can be a method in which the core network divides paging packets based on UE attributes. Here, UE attributes may include, but are not limited to: UE service type, UE transmission quantity, UE transmission bandwidth, etc.

[0329] The second type of paging packet method can be a method in which the base station divides paging packets based on the UE identification information (UE-ID). For example, the base station can use expression (1) to determine the UE's paging packets.

[0330] In the second type of PEI, each bit can be used to indicate whether one or more paging packets have been activated within a predetermined PO. Here, the paging packets can include paging packets classified using the first type of paging packet method, or paging packets classified using the second type of paging packet method.

[0331] For example, the second type of PEI may have 8 bits, wherein each of the 4 bits is used to indicate one of the 4 paging packets divided using the first type of paging packet method, and each of the other 4 bits is used to indicate one of the 4 paging packets divided using the second type of paging packet method.

[0332] The second type of PEI corresponds at least to the first type of paging packet mode, and may include the second type of PEI that corresponds only to the first type of paging packet mode, or the second type of PEI that corresponds to both the first type of paging packet mode and the second type of paging packet mode.

[0333] The second type of PEI corresponds at least to the second type of paging packet mode, and may include the second type of PEI that corresponds only to the second type of paging packet mode, or may include the second type of PEI that corresponds to both the first type of paging packet mode and the second type of paging packet mode.

[0334] The capability indication information indicates whether the UE supports PEIs corresponding to different types of paging packets. The base station can determine the UE's support capability for PEIs corresponding to different paging packet types. Then, the base station can send the UE's corresponding PEI for the paging packet type to wake up the UE to listen to the PO, reducing the chance of the UE being woken up in the PO of other types of paging packets and reducing the power consumption caused by the UE being woken up in invalid POs.

[0335] In one embodiment, receiving the first capability indication information includes at least one of the following:

[0336] Receive information from the UE indicating whether the UE supports the first capability indication information corresponding to at least the second type of PEI of the first type of paging packet mode;

[0337] Receive information from the base station indicating whether the UE supports the first capability indication information of the first type of PEI;

[0338] The UE receives first capability indication information from the base station indicating whether it supports at least the second type of PEI corresponding to the second type of paging packet mode.

[0339] Capability indication information can be sent by the UE to the core network. For example, the UE can carry capability indication information via NAS signaling.

[0340] For example, whether a UE supports at least a second type of PEI corresponding to a first type of paging packet mode can be reported by the UE to the core network via NAS signaling. Therefore, the capability indication information sent by the core network to the base station can also indicate whether the UE supports at least a second type of PEI corresponding to a first type of paging packet mode.

[0341] For example, whether a terminal supports at least the second type of PEI corresponding to the first type of paging packet mode is determined by the base station through a display indication based on the capability indication information sent by the core network.

[0342] After receiving the capability indication information reported by the UE, the base station can report the UE's capabilities to the core network. The capability indication information reported by the UE can indicate whether the UE supports Type I PEI and / or whether the UE supports Type II PEI corresponding to at least Type II paging packet mode. Therefore, the capability indication information sent by the base station can also indicate whether the UE supports Type I PEI and / or whether the UE supports at least Type II PEI corresponding to at least Type II paging packet mode.

[0343] For example, the UE reports its PEI support capability to the base station via capability indication information, and the base station then notifies the core network via capability indication information. The capability indication information can indicate whether the UE supports Type I PEI, and / or whether the UE supports Type II PEI corresponding to at least Type II paging packet mode. Whether the UE supports Type II PEI corresponding to at least Type I paging packet mode is transmitted by the terminal to the core network via NAS signaling; therefore, the base station does not need to report it.

[0344] For example, capability indication information can be carried in the following message:

[0345] UE CAPABILITY INFORMATION;

[0346] RRC INACTIVE TRANSITION REPORT.

[0347] like Figure 10 As shown, this exemplary embodiment provides an information transmission method, the method further comprising at least one of the following:

[0348] Step 1001a: Send second UE capability indication information to the base station, indicating whether the UE supports the first type of PEI;

[0349] Step 1001b: Send a second UE capability indication message to the base station indicating whether the UE supports the second type of PEI.

[0350] Here, steps 1001a and / or 1001b can be implemented individually or in combination with step 901.

[0351] Capability indication information can also be sent from the core network to the base station. The capability indication information indicates whether the UE supports Type I PEI and whether the UE supports Type II PEI corresponding to at least Type II paging packet mode.

[0352] Whether a UE supports at least a Type 2 PEI corresponding to a Type 1 paging packet mode can be reported by the UE to the core network via NAS signaling. Therefore, the capability indication information sent by the core network to the base station can also indicate whether the UE supports at least a Type 2 PEI corresponding to a Type 1 paging packet mode.

[0353] For example, whether a terminal supports at least the second type of PEI corresponding to the first type of paging packet mode is determined by the base station through a display indication based on the capability indication information sent by the core network.

[0354] The capabilities of the UE can also be transmitted between base stations. Capability indication information can be sent by the peer base station.

[0355] The following provides a specific example in conjunction with any of the above embodiments:

[0356] 1. The method by which the base station obtains the terminal's support for Advance Paging Indication (PEI);

[0357] 2. The base station learns whether the UE supports the paging packet scheme capability from the capability indication information reported by the terminal;

[0358] a) This information is used by the network as a reference for paging packets;

[0359] (b) As one embodiment, the paging packet scheme capability can be the terminal reporting its ability to support the UE-ID paging packet scheme; here, supporting the UE-ID paging packet scheme means that the terminal supports the second type of PEI corresponding to the second type of paging packet mentioned above. (The terminal is: a capability type 2 terminal)

[0360] c) As one embodiment, the paging grouping scheme capability can be the terminal's ability to report its support for PEI schemes; here, the ability to support PEI means that the terminal supports the first type of PEI mentioned above. (The terminal is: a capability type 1 terminal). If the first type of PEI is used to carry a non-grouped paging advance indication, then it includes the capability to support non-grouped PEI.

[0361] Signaling design format:

[0362] Capabiltiy1-PEI ENUMERATED{true}OPTIONAL,

[0363] Capabiltiy2-UEID-subgrouping ENUMERATED{true}OPTIONAL,

[0364] Furthermore, there are multiple ways to classify terminal capabilities:

[0365] 1) Method 1

[0366] The various abilities are not related;

[0367] Terminals with reporting capability 1 support PEI monitoring;

[0368] Terminals with reporting capability 2 support PEI packet paging monitoring;

[0369] That is, the two capabilities are reported independently.

[0370] 2) Method 2

[0371] Support for Capability 2 implicitly indicates support for Capability 1; that is, Capability 2 is a subset of Capability 1. A terminal can further indicate support for Capability 2 based on reporting Capability 1 as true. (In this case, both types of terminals can be collectively referred to as terminals supporting PEI capabilities.)

[0372] The terminal can report only support capability 1; (capability 2 is implicitly not supported).

[0373] The terminal can simultaneously report support for capability 1 and support for capability 2; that is, both flags are reported as true.

[0374] A terminal can report support for capability 1 while not supporting capability 2. It can indicate support for only capability 1 by not reporting the flag, i.e., implicitly indicating lack of support for capability 2 by using the flag's absence.

[0375] The terminal may only report support for capability 2; reporting support for capability 2 implies that the terminal also supports capability 1.

[0376] 2) Method 3

[0377] The terminal only reports its capability to support the UE-ID paging packet scheme (Capability 2) to the base station;

[0378] The base station obtains information from the core network as to whether the terminal supports the core network paging packet scheme; that is, whether the terminal has capability 3 from the core network. The base station combines the two methods to obtain the terminal's capability; here, the capability to support the core network paging packet scheme means that the terminal supports the second type PEI corresponding to the first type of paging packet mentioned above.

[0379] If the base station obtains that the terminal supports either the UE-ID paging packet scheme (Capability 2) or the core network paging packet scheme (Capability 3), meaning it supports at least one of these, then it supports PEI, i.e., the terminal supports Capability 1. In this case, the PEI support capability is implicitly expressed by the terminal's support for either the UE-ID paging packet scheme (Capability 2) or the core network paging packet scheme (Capability 3). That is, if the terminal supports either the UE-ID paging packet scheme or the core network paging packet scheme, it indicates that the terminal supports PEI.

[0380] If the base station finds that the terminal does not support the UE-ID paging packet scheme (capability 2) and does not support the core network paging packet scheme (capability 3), that is, it does not support either of them, then it does not support PEI, meaning that the terminal does not support capability 1.

[0381] For ease of understanding, the reason for using whether the terminal supports the paging packet scheme to express whether the terminal supports PEI is because in Release 17, paging packet information is sent solely using PEI. PEI is currently primarily used to handle paging packet information.

[0382] For example, the base station can obtain information that the terminal supports the UE-ID paging grouping scheme by having the base station carry the support in the capability indication information reported by the UE.

[0383] For example, the base station may obtain that the terminal does not support the UE-ID paging grouping scheme if the base station receives a capability indication information report from the UE that does not support it, or if it does not receive a report indication.

[0384] The base station can obtain the terminal's ability to support the core network paging packet scheme (Capability 3) by obtaining the packet ID from the core network. If the core network has assigned a packet ID to the user, it is determined that the terminal must have the ability to support the core network paging packet scheme; this is an implicit indication.

[0385] The base station obtains the terminal's ability to support the core network paging packet scheme (Capability 3) by receiving a display indication from the core network whether it supports or does not support it; that is, there is a display indication bit to indicate whether it supports it.

[0386] 3. The terminal's reporting capability informs the base station.

[0387] 1) Reporting via existing UE capabilities

[0388] 2) Report via Uplink Assistant Info (UAI);

[0389] As one embodiment, the UE can report this auxiliary information when it expects to leave the connected state. The reference auxiliary information of the paging packet is only useful when the terminal leaves the connected state.

[0390] 4. The terminal's reporting capability can be transmitted between the core network and the base station;

[0391] a) For example, the capabilities reported by the terminal include capability 1 and capability 2;

[0392] b) As one example: the UE reports its capabilities to the base station, and the base station then notifies the core network (capability 1 or capability 2) through the UE CAPABILITY INFOINDICATION; capability 3 is transmitted by the terminal to the core network through NAS, so it does not need to be directly reported to the base station.

[0393] The UE's capabilities can also be reported to the base station via the following messages:

[0394] RRC INACTIVE TRANSITION REPORT

[0395] c) As one example: the core network transmits the paging message to the base station

[0396] Display method: The paging message carries UE capability information (capability 1 and / or capability 2 or capability 3), where capability 3 is transmitted by the terminal to the core network through NAS.

[0397] Capability 3 can be indicated through both explicit and implicit methods.

[0398] An implicit indication, as mentioned above, is that the paging message carries paging packet information allocated by the core network, which indicates that the terminal has capability 3.

[0399] d) As an example: The core network transmits UE capabilities to the base station in the following message.

[0400] INITIAL CONTEXT SETUP REQUEST;

[0401] UE CONTEXT MODIFICATION REQUEST

[0402] HANDOVER REQUEST;

[0403] PATH SWITCH REQUEST ACKNOWLEDGE;

[0404] 5. Based on 1; Terminal capabilities: Capability 1 and / or Capability 2, and whether the terminal supports the core network paging packet scheme (Capability 3) can be transmitted between base stations;

[0405] Scenario 1: When a handover occurs, the base station obtains the terminal's capabilities from the handover request message.

[0406] Scenario 2: When an inactive user undergoes cell reselection, the base station obtains the terminal's capabilities from the anchor base station.

[0407] a) As one example, the UE context response may carry the terminal's capabilities;

[0408] b) As one embodiment, the RAN Paging message carries indication information of the UE's capabilities;

[0409] The target base station (the peer base station) can directly obtain capability 1;

[0410] The target base station can directly obtain capability 2;

[0411] The target base station can directly obtain capability 3;

[0412] The target base station can directly obtain information about capability 1 by knowing that capability 2 or capability 3 is supported;

[0413] The target base station can directly infer that it does not support capability 1 because it does not support capability 1 and does not support capability 2.

[0414] The group ID carried by the core network implicitly indicates the terminal's supported capability 3.

[0415] 6. The terminal core network determines the following behavior based on the terminal's capabilities and the paging scheme support capabilities of the base station:

[0416] a) The paging scheme support capability of the base station will be notified to the UE via public or private signaling methods;

[0417] b) Terminals with PEI support capability will listen for PEI or paging messages based on the base station's capability and their own capability; (the network contains terminals with capability 1, capability 2, capability 3, and terminals with both capability 2 and capability 3).

[0418] Base station capabilities are divided into two categories: non-packet PEI and packet PEI. These are categorized as: Category 1 base station capabilities and Category 2 base station capabilities.

[0419] Case 1:

[0420] Base station transmits non-packet PEI: Terminals supporting capability 1, capability 2, capability 3, and terminals with both capability 2 and capability 3 need to listen and be woken up;

[0421] Only terminals that support Capability 1 support this type of PEI. In this case, the PEI will be used to listen for paging messages (i.e., the terminal will be woken up by this PEI).

[0422] Alternatively, terminals supporting Capability 2 and / or 3 may support this type of PEI, in which case the PEI will be used for paging message listening (i.e., being woken up by this PEI).

[0423] Listening for paging messages using PEI means whether to listen for subsequent POs based on the PEI's instructions; listening for paging messages without using PEI means not listening for subsequent POs based on the PEI's instructions, i.e., directly listening for POs, which is the traditional (legacy) paging listening method.

[0424] Terminals that report support capability 1 will support this type of PEI, and at this time, they will use the PEI to listen for paging messages (i.e., be woken up by this PEI).

[0425] Alternatively, in addition to supporting capability 1, terminals with capabilities 2 / 3 can further support this type of PEI. In this case, PEI will also be used for paging message listening (i.e., being woken up by this PEI).

[0426] Terminals that support Capability 1 can use PEI to listen for paging messages (i.e., be woken up by the PEI) if they are supported by Capability 2 or Capability 3.

[0427] If a terminal does not support either capability 2 or capability 3, it is inferred that it does not support capability 1. In this case, it reverts to legacy paging.

[0428] Case 2:

[0429] Base station transmits PEI packets: Base station capabilities are divided into transmitting core network PEI packets, UE-ID PEI packets, or simultaneously supporting core network PEI packets and UE-ID PEI packets, which are respectively referred to as the second type of base station capability, the third type of base station capability, and the fourth type of base station capability.

[0430] A. Users who only support Capability 1 will not be able to support this type of PEI, and will not be able to use group PEI to listen for paging messages; that is, users can only return to the traditional (Legacy) listening mode (i.e., no PEI listening is required).

[0431] How to determine if a terminal only supports capability 1 can be discussed in several cases:

[0432] 1) Method 1, that is, reporting separately only supports capability 1;

[0433] 2) Method 2: As described above, only capability 1 is supported;

[0434] 3) Method 3: Terminals that are not supported by either Capability 2 or Capability 3

[0435] Terminals with paging packet capability (those supported by capability 2 or capability 3) will monitor PEI: Specifically:

[0436] B. For base stations that only support UE-ID packet mode (Category II base station capability):

[0437] Terminals supporting Capability 2 can use packet PEI to listen for paging messages (regardless of whether they have been assigned a group ID by the core network); it is necessary to check whether the packet to which it belongs has been woken up;

[0438] Terminal users that do not support the UE-id grouping method, such as UE capability 3 terminals, will not be able to support this type of PEI. In this case, they cannot use grouped PEI to listen for paging messages; that is, users can only return to the traditional (Legacy) listening mode (i.e., no PEI listening is required).

[0439] C. For base stations that only support CN-assgin packet mode (Category III base station capability):

[0440] Terminals that support Capability 3 can use packet PEI to listen for paging messages; terminals that do not have Capability 3 do not listen for PEI.

[0441] Furthermore, users who are assigned a groupID by the core network only need to determine whether their group has been woken up; users who are not assigned a groupID do not need to listen to PEI. Because users who are not assigned a groupID by the core network do not need to listen to PEI even if they have the capability to support capability 3, it simplifies the process and saves power.

[0442] Terminals that only support capability 2 (i.e., terminals that only support UE-id packet mode and not CN packet mode) will not be able to support this type of PEI. In this case, they cannot use packet PEI to listen for paging messages; that is, users can only return to the traditional listening mode (i.e., no PEI listening is required).

[0443] In this way, when the terminal obtains the capabilities of the base station and discovers that the type of the paging PEI sent by the base station does not match its own support capabilities, there is no need to listen for the PEI, which simplifies the process and saves power.

[0444] D. For base stations that support CN-assgin packet mode + UE-ID packet mode (Category IV base station capability):

[0445] Terminal users that support UE-ID or CN packet methods will use packet PEI to listen for paging messages; it is necessary to check whether the packet to which it belongs has been woken up;
