[0039] 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.

[0040] The terminal 11 can be a device that provides voice and / or data connectivity to a user. The terminal 11 can communicate with one or more core networks via a Radio Access Network (RAN), and the terminal 11 can be an Internet of Things terminal, such as a sensor device, a mobile phone (or called "cellular" phone), and a computer with an Internet of Things terminal, for example, which can be fixed, portable, pocket-sized, handheld, built-in a computer, or vehicle-mounted. For example, a Station (STA), a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, an access point, a remote terminal, an access terminal, a user terminal, a user agent, a user device, or a user equipment (UE). Alternatively, the terminal 11 can also be a device of an unmanned aerial vehicle. Alternatively, the terminal 11 can also be a vehicle-mounted device, for example, it can be a vehicle-mounted computer with wireless communication function, or a wireless communication device externally connected to the vehicle-mounted computer. Alternatively, the terminal 11 can also be a roadside device, for example, it can be a street lamp, a signal lamp, or other roadside devices with wireless communication function, etc.

[0041] The base station 12 can be a network-side device in a wireless communication system. The wireless communication system can be a 4th generation mobile communication (4G) system, also known as a Long Term Evolution (LTE) system, or the wireless communication system can also be a 5G system, also known as a new radio (NR) system or a 5G NR system. Alternatively, the wireless communication system can also be a next generation of 5G system. In the 5G system, the access network can be referred to as an NG-RAN (New Generation-Radio Access Network). Alternatively, the MTC system.

[0042] The base station 12 can be an evolved NodeB (eNB) in a 4G system. Alternatively, the base station 12 can be a base station (gNB) in a 5G system employing a centralized and distributed architecture. When the base station 12 employs a centralized and distributed architecture, it generally includes a central unit (CU) and at least two distributed units (DUs). The central unit is provided with a protocol stack of a Packet Data Convergence Protocol (PDCP) layer, a Radio Link Control (RLC) layer, and a Media Access Control (MAC) layer, and the distributed unit is provided with a protocol stack of a Physical (PHY) layer. The specific implementation of the base station 12 is not limited in the embodiments of the present disclosure.

[0043] The base station 12 and the terminal 11 can establish a wireless connection through a wireless air interface. In different embodiments, the wireless air interface is a wireless air interface based on a fourth generation mobile communication network technology (4G) standard; or the wireless air interface is a wireless air interface based on a fifth generation mobile communication network technology (5G) standard, such as a new radio interface; or the wireless air interface can also be a wireless air interface based on a more next generation mobile communication network technology standard of 5G.

[0044] In some embodiments, the terminals 11 can also establish an E2E (End to End) connection. For example, V2V (vehicle to vehicle) communication, V2I (vehicle to infrastructure) communication, and V2P (vehicle to pedestrian) communication in vehicle to everything (V2X) communication scenarios.

[0045] In some embodiments, the wireless communication system can also include a network management device 13.

[0046] A plurality of base stations 12 are connected to a network management device 13. The network management device 13 can be a core network device in a wireless communication system, for example, the network management device 13 can be a Mobility Management Entity (MME) in an Evolved Packet Core (EPC). Alternatively, the network management device can also be another core network device, such as a Serving GateWay (SGW), a Public Data Network GateWay (PGW), a Policy and Charging Rules Function (PCRF), a Home Subscriber Server (HSS), etc. The implementation form of the network management device 13 is not limited in the embodiments of the present disclosure.

[0047] The execution subject involved in the embodiments of the present disclosure includes but is not limited to: a mobile phone terminal in a cellular mobile communication system, and a network side device, such as an access network device (e.g., a base station) and a core network.

[0048] For the case that all UEs are woken up within a PO, the UEs can be grouped for paging. The grouping information can be carried in a Paging DCI or a Paging Earlier Indication (PEI). The UE determines whether to wake up within a PO based on the grouping information. The grouping information can be used to determine the group to which the UE belongs. For example, the grouping information can include: a group identifier, etc.

[0049] One grouping manner is to group based on UE identification information (UE-ID). The grouping can be determined based on expression (1):

[0050] (1)

[0051] wherein, indicates the index of different paging grouping resources. The UE-ID modulo manner is a random selection or random allocation manner (randomization). That is, the UE-ID is moduloed in all paging grouping resources. Wherein, indicates the paging frame density in the time domain, indicates the paging density within one paging frame in the time domain; indicates a paging narrowband; indicates the total number of paging grouping resources.

[0052] Another grouping manner is performed by the core network as a unified node. A subgroup ID is directly allocated in NR. When the subgroup ID is allocated, the network will be based on the implementation allocation, such as according to the terminal attribute, or the statistical paging probability, etc.

[0053] Exemplarily, the PEI can use 1 bit to wake up all UEs, that is, to wake up the ungrouped UEs.

[0054] Therefore, in the case of using two paging grouping manners, and the PEI can wake up the ungrouped UEs, how the UE wakes up based on the PEI is a problem to be solved.

[0055] As Figure 2 shown, the present exemplary embodiment provides an information transmission method, which can be executed by a base station of a cellular mobile communication system, comprising:

[0056] Step 201: receiving first capability indication information, wherein the first capability indication information indicates whether the UE supports PEI.

[0057] The PEI can be used to indicate the UE to wake up and listen to the paging message in a predetermined paging occasion (PO). Here, the predetermined PO can include one or more POs after the PEI. Whether to support PEI can include but not limited to whether to support the indication based on PEI to wake up in the predetermined PO.

[0058] The PEI can be used to wake up all UEs, or can be used to wake up UEs in a predetermined range (such as a predetermined group, a predetermined type, etc.). The PEI can contain indication information for different grouped UEs, for waking up UEs in different groups. Whether to support PEI can include but not limited to whether to support the PEI to wake up all UEs, and / or whether to support the PEI to wake up UEs in a predetermined range.

[0059] The capability indication information can be sent by the UE to the base station, or can be sent by the core network to the base station, or can be sent by the opposite base station.

[0060] The UE can carry the capability indication information through the uplink signaling in the random access process, or after establishing the RRC connection, etc.

[0061] After receiving the capability indication information, the base station can determine whether the UE supports PEI. If the UE supports PEI, the base station wakes up the UE to monitor the PO using the PEI supported by the UE. Thus, the case that the base station cannot determine whether the UE supports PEI, sends the PEI to the UE when the UE does not support PEI, or does not send the PEI to the UE when the UE supports PEI is reduced. Sending the PEI to the UE when the UE does not support PEI increases the workload of the base station; and when the UE supports PEI, the UE needs to frequently wake up to monitor the PO due to the UE cannot receive the PEI, which causes the UE power consumption.

[0062] Thus, whether the UE supports PEI is indicated by the capability indication information. The base station can determine the PEI capability of the UE, reduce the misjudgment of the UE capability due to the base station cannot determine the PEI capability of the UE, and improve the accuracy of the determination of the PEI capability of the UE by the base station.

[0063] In one embodiment, the first capability indication information is used to indicate at least one of the following:

[0064] whether the UE supports the first type of PEI;

[0065] whether the UE supports the second type of PEI, wherein the first type of PEI is different from the second type of PEI.

[0066] In one embodiment, the first type of PEI can have 1 bit to indicate whether the UE wakes up. In addition to being used as a paging indication, the first type of PEI can be used to carry other information in subsequent extensions. For example, it can carry reference signal availability indication information. In this paper, the preferred embodiment of the first type of PEI is used to indicate non-grouped PEI.

[0067] In one embodiment, the second type of PEI can have multiple bits to indicate whether the UE wakes up.

[0068] The first type of PEI is a common PEI that can be used to wake up all UEs that need to monitor the same PO;

[0069] The second type of PEI is a PEI for paging groups, which can be used to wake up all UEs within the paging group corresponding to the same PO according to the paging group.

[0070] When the PEI has 1 bit, i.e., the PEI is the first type of PEI, the PEI can be used to wake up all UEs that receive the PEI. That is, the first type of PEI does not distinguish the paging group of the UE.

[0071] When the PEI has multiple bits, i.e., the PEI is a second type of PEI, each bit of the multiple bits can be used to wake up one or more UEs of a paging group. That is, the second type of PEI distinguishes the paging groups of UEs.

[0072] For example, the PEI can include POnumPerPEI segments, which can be referred to as a subgroupsNumPerPO field. Each segment can correspond to one PO. Each segment contains subgroupsNumPerPO bits, each of which carries a paging indication indicating whether one or more paging groups are to be woken up in the corresponding PO.

[0073] When the PEI is a first type of PEI, the subgroupsNumPerPO field has one bit of the paging indication bit, which is used to wake up all UEs receiving the PEI to listen for paging messages in the PO. For example, when the paging indication bit is “1”, all UEs receiving the PEI are woken up to listen for paging messages in the PO period, and when the paging indication bit is “0”, the UEs are instructed to remain in a sleep state, such as remaining in an RRC idle state or an RRC inactive state, etc., in the PO period.

[0074] When the PEI is a second type of PEI, the subgroupsNumPerPO field has multiple bits, each of which can correspond to a paging group, and UEs of different paging groups determine whether to wake up in the PO period based on the bit corresponding to their own paging group. For example, the subgroupsNumPerPO field has two bits corresponding to two paging groups, and when one of the bits is “1”, the UEs of the paging group corresponding to the bit are woken up to listen for paging messages in the PO, and when one of the bits is “0”, the UEs of the paging group corresponding to the bit are instructed to remain in a sleep state in the PO.

[0075] The capability indication information can be used to indicate whether the UE supports the first type of PEI and / or the second type of PEI.

[0076] If the capability indication information indicates that the UE supports the first type of PEI, the base station can use the first type of PEI to wake up the UE to listen for the PO. This reduces the need for the UE to wake up in each PO, reducing power consumption of the UE.

[0077] If the capability indication information indicates that the UE supports the second type of PEI, the base station can use the second type of PEI to wake up the UE to listen for the PO based on the paging group. This reduces the need for the UE to wake up in the PO when the paging group to which the UE belongs is not paged, reducing power consumption of the UE.

[0078] Thus, whether the UE supports the PEI is indicated by the capability indication information. The base station can determine the PEI capability of the UE, and then based on the PEI capability of the UE, the UE is woken up to monitor the PO by sending the PEI supported by the UE, and the UE is not woken up to monitor when the UE does not need to be woken up, reducing the power consumption caused by the frequent wakening of the UE.

[0079] In an embodiment, whether the UE supports the second type of PEI includes at least one of:

[0080] Whether the UE supports the second type of PEI corresponding to at least the first type of paging grouping manner;

[0081] Whether the UE supports the second type of PEI corresponding to at least the second type of paging grouping manner.

[0082] The first type of paging grouping manner and the second type of paging grouping manner divide the paging groups in different ways. The first type of paging grouping manner and the second type of paging manner can also be performed by different network nodes. The first type of paging and the second type of paging can also be performed by the same network node.

[0083] The core network or the base station, etc. can respectively divide the paging groups in different paging grouping manners, thereby generating different types of paging groups. Each paging grouping manner can divide a plurality of paging groups. For example, grouping can be performed based on the service type of the UE, or grouping can be performed based on the transmission rate of the UE, etc.

[0084] The second type of PEI corresponding to at least the first type of paging grouping manner can be used to at least indicate whether the UE corresponding to the paging group of the first type of paging grouping manner is woken up.

[0085] The second type of PEI corresponding to at least the second type of paging grouping manner can be used to at least indicate whether the UE corresponding to the paging group of the second type of paging grouping manner is woken up.

[0086] In an embodiment,

[0087] The first type of paging grouping manner includes a paging grouping manner in which the paging groups are determined by the core network;

[0088] The second type of paging grouping manner includes a paging grouping manner in which the paging groups are determined based on the UE identifier.

[0089] The first type of paging grouping manner can be a manner in which the paging groups are divided by the core network based on the UE attribute. Here, the UE attribute can include but is not limited to the service type of the UE, the transmission quantity of the UE, the transmission bandwidth of the UE, etc.

[0090] 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.

[0091] 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.

[0092] 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.

[0093] 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.

[0094] 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.

[0095] 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.

[0096] like Figure 3 As shown, this exemplary embodiment provides an information transmission method, the method further comprising at least one of the following:

[0097] 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;

[0098] 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.

[0099] Here, the step 301a or 301b can be implemented alone or in combination with the step 201.

[0100] The capability indication information can indicate whether the UE supports PEI, and PEI corresponding to different paging packet directions, etc. by explicit indication.

[0101] For example, when the capability indication information indicates that the UE supports the second type of PEI, the capability indication information can implicitly indicate that the UE also supports the first type of PEI. Here, the second type of PEI can include: the second type of PEI corresponding to at least the first type of paging packet manner, and / or the second type of PEI corresponding to at least the second type of paging packet manner.

[0102] For example, when the capability indication information indicates that the UE does not support the second type of PEI, the capability indication information implicitly indicates that the UE also does not support the first type of PEI. Here, the second type of PEI can include: the second type of PEI corresponding to at least the first type of paging packet manner, and the second type of PEI corresponding to at least the second type of paging packet manner.

[0103] The capability indication information using explicit indication and / or implicit indication can be specified by a communication protocol, or can be mutually agreed between the core network, the base station and the UE.

[0104] The capability indication information using explicit indication and / or implicit indication can use, but is not limited to, the following ways:

[0105] Method 1: Whether the UE supports the first type of PEI and the second type of PEI can be indicated separately.

[0106] The capability indication information can separately indicate to the base station that the UE supports the first type of PEI.

[0107] The capability indication information can separately indicate to the base station that the UE supports the second type of PEI corresponding to at least the second type of paging packet manner.

[0108] Method 2: Whether the UE supports the first type of PEI and the second type of PEI is indicated by one capability indication information.

[0109] The capability indication information indicates that the UE supports the second type of PEI, and implicitly indicates that the UE supports the first type of PEI.

[0110] If the UE supports the first type of PEI, the UE can further indicate support for the second type of PEI on the basis of reporting capability indication information indicating support for the first type of PEI.

[0111] The UE can only report the capability indication information to indicate that the first type of PEI is supported, while implicitly indicating that the second type of PEI is not supported.

[0112] The UE can report the capability indication information to indicate that the first type of PEI and the second type of PEI are both supported; the capability indication information can use two flags to respectively indicate that the UE supports the first type of PEI and the second type of PEI.

[0113] The UE can report the capability indication information to indicate that the first type of PEI is supported, but the second type of PEI is not supported; the UE can express that only the first type of PEI is supported by not reporting the flag, i.e., the absence of the flag implicitly indicates that the second type of PEI is not supported.

[0114] The UE can report the capability indication information to indicate that the second type of PEI is supported; the implicit expression of reporting that the second type of PEI is supported is that the UE also supports the first type of PEI.

[0115] The capability indication information reported by the UE to indicate whether the UE supports the second type of PEI can include information indicating whether the UE supports the second type of PEI corresponding to at least the second type of paging grouping mode.

[0116] Method 3: The UE can only report to the base station whether the UE supports the second type of PEI corresponding to at least the second type of paging grouping mode.

[0117] The base station can also obtain from the core network the capability indication information of whether the UE supports the second type of PEI corresponding to at least the first type of paging grouping mode; i.e., the base station obtains from the core network whether the UE supports the second type of PEI corresponding to at least the first type of paging grouping mode, and the base station combines the two ways to obtain the capability of the UE;

[0118] The base station determines that the UE supports the first type of PEI when the UE supports the second type of PEI corresponding to at least the first type of paging grouping mode, or supports the second type of PEI corresponding to at least the second type of paging grouping mode.

[0119] The base station determines that the UE does not support the first type of PEI when the UE does not support the second type of PEI corresponding to at least the first type of paging grouping mode, and does not support the second type of PEI corresponding to at least the second type of paging grouping mode.

[0120] In one embodiment, the receiving the first capability indication information includes at least one of:

[0121] The first capability indication information sent by the UE to indicate whether the UE supports the first type of PEI is received;

[0122] receiving the first capability indication information indicating whether the UE supports the second type of PEI corresponding to at least the second type of paging grouping manner;

[0123] receiving the first capability indication information sent by the core network;

[0124] receiving the first capability indication information sent by the peer base station.

[0125] The UE can determine whether it supports the first type of PEI, and thus can send the capability indication information to the base station to indicate whether the UE supports the first type of PEI.

[0126] The UE can determine whether it supports the second type of PEI corresponding to at least the second type of paging grouping manner. For example, the UE can determine whether it supports the paging grouping manner based on UE_ID, and thus can send the capability indication information to the base station to indicate whether the UE supports the second type of PEI corresponding to at least the second type of paging grouping manner.

[0127] For example, the base station determines that the UE supports the second type of PEI corresponding to at least the second type of paging grouping manner based on the capability indication information reported by the UE. The base station determines that the UE does not support the second type of PEI corresponding to at least the second type of paging grouping manner based on the capability indication information reported by the UE. Alternatively, if the base station does not receive the capability indication information, it determines that the UE does not support the second type of PEI corresponding to at least the second type of paging grouping manner.

[0128] In one embodiment, the capability indication information can be carried in the UE capability information (UECapabilityInformation) or the uplink assistance message. The UE capability information is used to at least indicate the frequency supported by the UE.

[0129] The UE can carry the capability indication information in the uplink assistance message when it is released from the RRC connected state.

[0130] The capability indication information can also be sent by the core network to the base station, and the capability indication information indicates whether the UE supports the first type of PEI and whether the UE supports the second type of PEI corresponding to at least the second type of paging grouping manner.

[0131] Whether the UE supports the second type of PEI corresponding to at least the first type of paging grouping manner can be reported by the UE to the core network through NAS signaling, and thus the capability indication information sent by the core network to the base station can also indicate whether the UE supports the second type of PEI corresponding to at least the first type of paging grouping manner.

[0132] For example, the base station determines whether the UE supports the second type of PEI corresponding to the first type of paging grouping mode based on the capability indication information sent by the core network.

[0133] The capability of the UE can also be transmitted between base stations. The capability indication information can be sent by the opposite base station.

[0134] For example, the UE can be a non-active UE, and the opposite base station can be an anchor base station of the UE. The anchor base station retains the capability indication information of whether the UE supports PEI. When the UE performs cell reselection in the coverage of the current base station, the current base station can obtain the capability indication information from the anchor base station, and then determine whether the UE supports PEI.

[0135] For example, when the non-active UE performs cell reselection, the base station obtains the reported capability of the UE from the anchor base station.

[0136] For example, the capability indication information can be carried in a UE context response sent to the base station. The capability indication information can be carried in a paging message from the core network and sent to the base station.

[0137] The base station can directly determine whether the UE supports the first type of PEI based on the capability indication information sent by the opposite base station.

[0138] The base station can directly determine whether the UE supports the second type of PEI corresponding to the first type of paging grouping mode based on the capability indication information sent by the opposite base station.

[0139] The base station can directly determine whether the UE supports the second type of PEI corresponding to the second type of paging grouping mode based on the capability indication information sent by the opposite base station.

[0140] The base station determines that the UE supports the first type of PEI based on that the UE supports the second type of PEI corresponding to the first type of paging grouping mode, or that the UE supports the second type of PEI corresponding to the second type of paging grouping mode.

[0141] The base station determines that the UE does not support the first type of PEI based on that the UE does not support the second type of PEI corresponding to the first type of paging grouping mode, or that the UE does not support the second type of PEI corresponding to the second type of paging grouping mode.

[0142] In one embodiment, the UE is determined to support the second type of PEI corresponding to the first type of paging grouping mode in response to the opposite base station sending grouping information of the first type of paging grouping mode of the UE.

[0143] In one embodiment, the receiving of the first capability indication information sent by the core network comprises:

[0144] In response to receiving the grouping information of the UE in the first paging grouping mode sent by the core network, it is determined that the UE supports the second PEI corresponding to at least the first paging grouping mode.

[0145] The first capability indication information can be grouping information of the UE in the first paging grouping mode. When the core network sends the grouping information of the UE in the first paging grouping mode to the base station, it can be determined that the UE supports the second PEI corresponding to at least the first paging grouping mode.

[0146] The grouping information can be used to indicate paging grouping. The grouping information can be a subgroup ID of the UE. If the core network allocates a subgroup ID for the UE, it can be determined that the terminal supports the second PEI corresponding to at least the first paging grouping mode. It can be considered that the grouping information sent by the core network is a kind of implicit expression that the terminal supports the second PEI corresponding to at least the first paging grouping mode.

[0147] For example, the terminal supports the second PEI corresponding to at least the first paging grouping mode, which is determined by the base station based on the subgroup ID sent by the core network.

[0148] As shown in Figure 4 The present exemplary embodiment provides an information transmission method, which further comprises at least one of the following:

[0149] Step 401a: sending second capability indication information indicating whether the UE supports the first PEI to a peer base station;

[0150] Step 401b: sending second capability indication information indicating whether the UE supports the second PE to a peer base station;

[0151] Step 401c: sending second capability indication information indicating whether the UE supports the first PEI to a core network;

[0152] Step 401d: sending second capability indication information indicating whether the UE supports the second PE corresponding to at least the second paging grouping mode to a core network.

[0153] Here, step 401a, step 401b, step 401c and / or step 401d can be implemented alone or in combination with step 301a, step 301b and / or step 201.

[0154] The capability of the UE can also be transmitted between base stations. The base station can send capability indication information to a peer base station.

[0155] For example, the UE can be an inactive UE, the peer base station can be a base station to which the UE performs cell reselection, the anchor base station retains the capability indication information of whether the UE supports PEI, and the anchor base station can send the capability indication information to the peer base station when the UE performs cell reselection in the coverage of the peer base station, and the peer base station can determine whether the UE supports PEI.

[0156] The capability indication information transmitted between the base stations can indicate at least one of whether the UE supports the first type of PEI and whether the UE supports the second type of PEI.

[0157] After receiving the capability indication information reported by the UE, the base station can report the capability of the UE to the core network. The capability indication information reported by the UE can be used to indicate whether the UE supports the first type of PEI and / or whether the UE supports the second type of PEI corresponding to at least the second type of paging grouping mode. Therefore, the capability indication information sent by the base station can also be used to indicate whether the UE supports the first type of PEI and / or whether the UE supports the second type of PEI corresponding to at least the second type of paging grouping mode.

[0158] For example, the UE reports the capability of the UE supporting PEI to the base station through the capability indication information, and the base station notifies the core network through the capability indication information. The capability indication information can indicate whether the UE supports the first type of PEI and / or whether the UE supports the second type of PEI corresponding to at least the second type of paging grouping mode. Whether the UE supports the second type of PEI corresponding to at least the first type of paging grouping mode is delivered to the core network by the terminal through NAS signaling, and therefore the base station does not need to report.

[0159] For example, the capability indication information can be carried in the following messages:

[0160] UE CAPABILITY INFO INDICATION;

[0161] RRC INACTIVE TRANSITION REPORT.

[0162] In an embodiment, the base station sends the PEI supported by the UE to the UE.

[0163] After determining the PEI that can be supported by the UE, the base station can send the PEI that can be supported by the UE to the UE in a subsequent paging process. In this way, the base station can send the PEI supported by the UE to wake up the UE to listen to the PO, and when the UE does not need to be woken up, the UE is not woken up to listen, thereby reducing the power consumption caused by frequent waking up of the UE.

[0164] As Figure 5 shown, the present exemplary embodiment provides an information transmission method, the method further comprising,

[0165] Step 501: sending third capability indication information to the UE, wherein the third capability indication information is used by the UE to determine the PEI that the base station is capable of sending.

[0166] Here, step 501 can be implemented alone or in combination with step 301a, step 301b, step 401a, step 401b, step 401c, step 401d and / or step 201.

[0167] The capability indication information can indicate the PEI that the base station is capable of sending. The UE can determine whether to monitor the PEI sent by the base station based on the PEI that the base station is capable of sending and the PEI that the UE itself supports.

[0168] For example, if the UE is capable of supporting the PEI sent by the base station, the UE can monitor the PEI. If the UE does not support the PEI sent by the base station, the UE can not monitor the PEI sent by the base station.

[0169] If the UE does not monitor the PEI of the base station, the UE can wake up and monitor the paging message in each PO.

[0170] The capability indication information can be carried in common signaling. For example, the capability indication information can be carried in a system message and broadcast to the UE.

[0171] The capability indication information can be carried in dedicated signaling. For example, the capability indication information can be carried in an RRC message and sent to the UE.

[0172] In one embodiment, the third capability indication information is used by the UE to determine at least one of the following that the base station is capable of sending:

[0173] The first type of PEI;

[0174] The second type of PEI corresponding to the first type of paging grouping mode, wherein the second type of PEI includes a plurality of bits;

[0175] The second type of PEI corresponding to the second type of paging grouping mode;

[0176] The second type of PEI corresponding to the first type of paging grouping mode and the second type of paging grouping mode.

[0177] For example, if the base station is capable of sending the first type of PEI, the UE supporting the first type of PEI can monitor the PEI and monitor the paging message based on the indication of the PEI.

[0178] For example, if the base station is capable of sending the first type of PEI, a UE that does not support the first type of PEI can not monitor the PEI and fall back to legacy paging, waking up to monitor paging messages at every PO.

[0179] For example, if the base station is capable of sending the second type of PEI corresponding to the first type of paging grouping, a UE that supports the second type of PEI corresponding to the first type of paging grouping can monitor the PEI and monitor paging messages based on the indication of the PEI.

[0180] In one embodiment, the UE determines whether to wake up at a PO based on its own grouping information of the first type of paging grouping and the indication of the PEI.

[0181] For example, the PEI can indicate the grouping in the first type of paging grouping that needs to wake up, and the UE can determine whether its own grouping needs to wake up.

[0182] For example, if the base station is capable of sending the second type of PEI corresponding to the first type of paging grouping, a UE that does not support the second type of PEI corresponding to the first type of paging grouping can not monitor the PEI and fall back to legacy paging, waking up to monitor paging messages at every PO.

[0183] In one embodiment, if the base station is capable of sending the second type of PEI corresponding to the first type of paging grouping, a UE that supports the second type of PEI corresponding to the first type of paging grouping can monitor the PEI sent by the base station only when it is configured with the grouping information of the first type of paging grouping, otherwise the UE does not monitor the PEI.

[0184] For example, if the base station is capable of sending the second type of PEI corresponding to the second type of paging grouping, a UE that supports the second type of PEI corresponding to the second type of paging grouping can monitor the PEI and monitor paging messages based on the indication of the PEI.

[0185] For example, if the base station is capable of sending the second type of PEI corresponding to the second type of paging grouping, a UE that does not support the second type of PEI corresponding to the second type of paging grouping can not monitor the PEI and fall back to legacy paging, waking up to monitor paging messages at every PO.

[0186] For example, the base station is capable of sending the second type of PEI corresponding to the first type of paging grouping and the second type of paging grouping, and if the UE supports at least the second type of PEI corresponding to the first type of paging grouping or supports at least the second type of PEI corresponding to the second type of paging grouping, the UE can monitor the PEI and monitor paging messages based on the indication of the PEI.

[0187] 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.

[0188] 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.

[0189] In one embodiment, 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, or the packet information of the UE's first type of paging packet method can be a group identifier determined based on the UE_ID.

[0190] 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:

[0191] Step 601: Send first capability indication information, wherein the first capability indication information indicates whether the UE supports PEI.

[0192] 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.

[0193] The PEI can be used to wake up all UEs or a predetermined range (e.g., a predetermined group, a predetermined type, etc.) of UEs. The PEI can contain indication information for different groups of UEs for waking up different groups of UEs. Whether to support the PEI can include, but is not limited to, whether to support the PEI for waking up all UEs and / or whether to support the PEI for waking up the predetermined range of UEs.

[0194] The UE can carry the capability indication information through uplink signaling in a random access procedure or after establishing an RRC connection, etc. The UE can also carry the capability indication information through NAS signaling, etc.

[0195] The capability indication information can be received by a base station or a core network, etc.

[0196] After receiving the capability indication information, the base station can determine whether the UE supports the PEI. If the UE supports the PEI, the base station uses the PEI supported by the UE to wake up the UE to monitor the PO. Thus, the case that the base station cannot determine whether the UE supports the PEI, sends the PEI to the UE when the UE does not support the PEI, or does not send the PEI to the UE when the UE supports the PEI is reduced. Sending the PEI to the UE when the UE does not support the PEI increases the workload of the base station, and not sending the PEI to the UE when the UE supports the PEI causes the UE to need to frequently wake up to monitor the PO due to the UE being unable to receive the PEI, resulting in power consumption of the UE.

[0197] In this way, the capability indication information indicates whether the UE supports the PEI. The base station can determine the PEI capability of the UE, reduce the misjudgment of the UE capability due to the base station being unable to determine the PEI capability of the UE, and improve the accuracy of the determination of the PEI capability of the UE by the base station.

[0198] In one embodiment, the first capability indication information is used to indicate at least one of the following:

[0199] Whether the UE supports a first type of PEI;

[0200] Whether the UE supports a second type of PEI, wherein the first type of PEI is different from the second type of PEI.

[0201] The first type of PEI can have one bit for indicating whether the UE is woken up. The second type of PEI can have multiple bits for indicating whether the UE is woken up.

[0202] The first type of PEI is a common PEI and can be used to wake up all UEs that need to monitor the same PO.

[0203] The second type of PEI is a PEI for a paging group and can be used to wake up all UEs in the paging group that monitor the same PO according to the paging group.

[0204] When the PEI has one bit, i.e., the PEI is a first type of PEI, the PEI can be used to wake up all UEs receiving the PEI. That is, the first type of PEI does not distinguish the paging groups of UEs.

[0205] When the PEI has multiple bits, i.e., the PEI is a second type of PEI, each bit of the multiple bits can be used to wake up one or more paging groups of UEs. That is, the second type of PEI distinguishes the paging groups of UEs.

[0206] For example, the PEI can include POnumPerPEI segments, which can be referred to as a subgroupsNumPerPO field. Each segment can correspond to one PO. Each segment contains subgroupsNumPerPO bits, each of which carries a paging indication indicating whether one or more paging groups are to be woken up in the corresponding PO.

[0207] When the PEI is a first type of PEI, the subgroupsNumPerPO field has one bit of the paging indication, which is used to wake up all UEs receiving the PEI to listen for paging messages in the PO. For example, when the paging indication bit is “1”, all UEs receiving the PEI are woken up to listen for paging messages in the PO period, and when the paging indication bit is “0”, the UE is instructed to remain in a sleep state, such as remaining in an RRC idle state or an RRC inactive state, etc., in the PO period.

[0208] When the PEI is a second type of PEI, the subgroupsNumPerPO field has multiple bits, each of which can correspond to a paging group, and UEs of different paging groups determine whether to wake up in the PO period based on the bit corresponding to their own paging group. For example, the subgroupsNumPerPO field has two bits corresponding to two paging groups, and when one of the bits is “1”, the UE of the paging group corresponding to the bit is woken up to listen for paging messages in the PO, and when one of the bits is “0”, the UE of the paging group corresponding to the bit is instructed to remain in a sleep state in the PO.

[0209] The capability indication information can be used to indicate whether the UE supports the first type of PEI and / or the second type of PEI.

[0210] If the capability indication information indicates that the UE supports the first type of PEI, the base station can use the first type of PEI to wake up the UE to listen for the PO. This reduces the need for the UE to wake up in each PO, reducing power consumption of the UE.

[0211] If the capability indication information indicates that the UE supports the second type of PEI, the base station can use the second type of PEI to wake up the UE to monitor the PO based on the paging group. The power consumption of the UE can be reduced when the UE is not paged in the paging group and is woken up to monitor the PO.

[0212] In this way, whether the UE supports PEI is indicated by the capability indication information. The base station can determine the PEI capability of the UE, and then send the PEI supported by the UE to wake up the UE to monitor the PO based on the PEI capability of the UE. When the UE does not need to be woken up, the UE is not woken up to monitor, and the power consumption caused by frequent wake-up of the UE is reduced.

[0213] In one embodiment, whether the UE supports the second type of PEI includes at least one of:

[0214] Whether the UE supports the second type of PEI corresponding to at least the first type of paging group mode;

[0215] Whether the UE supports the second type of PEI corresponding to at least the second type of paging group mode.

[0216] The first type of paging group mode and the second type of paging group mode divide the paging group in different ways. The first type of paging group mode and the second type of paging mode can also be performed by different network nodes. The first type of paging and the second type of paging can also be performed by the same network node.

[0217] The core network or the base station, etc. can divide the paging group in different paging group modes respectively, thereby generating different types of paging groups. Each paging group mode can divide a plurality of paging groups. For example, grouping can be based on the service type of the UE, or grouping can be based on the transmission rate of the UE, etc.

[0218] The second type of PEI corresponding to at least the first type of paging group mode can be used to at least indicate whether the UE corresponding to the paging group of the first type of paging group mode is woken up.

[0219] The second type of PEI corresponding to at least the second type of paging group mode can be used to at least indicate whether the UE corresponding to the paging group of the second type of paging group mode is woken up.

[0220] In one embodiment, the first type of paging group mode includes: a paging group mode in which the paging group is determined by the core network;

[0221] The second type of paging group mode includes: a paging group mode in which the paging group is determined based on the UE identifier.

[0222] The first type of paging grouping manner can be a manner of grouping paging by the core network based on UE attributes. Here, the UE attributes can include, but are not limited to, a service type of the UE, a transmission quantity of the UE, a transmission bandwidth of the UE, and the like.

[0223] The second type of paging grouping manner can be a manner of grouping paging by the base station based on UE identification information (UE-ID). For example, the base station can determine the paging grouping of the UE by using expression (1)

[0224] Each bit of the plurality of bits of the second type of PEI can be used to indicate whether one or more paging groupings are to wake up within a predetermined PO. Here, the paging groupings can include paging groupings grouped by the first type of paging grouping manner or paging groupings grouped by the second type of paging grouping manner.

[0225] For example, the second type of PEI can have 8 bits, wherein each of the 4 bits is used to indicate one of 4 paging groupings grouped by the first type of paging grouping manner, and each of the other 4 bits is used to indicate one of 4 paging groupings grouped by the second type of paging grouping manner.

[0226] The second type of PEI corresponding to at least the first type of paging grouping manner can include a second type of PEI corresponding only to the first type of paging grouping manner, or can include a second type of PEI corresponding to both the first type of paging grouping manner and the second type of paging grouping manner.

[0227] The second type of PEI corresponding to at least the second type of paging grouping manner can include a second type of PEI corresponding only to the second type of paging grouping manner, or can include a second type of PEI corresponding to both the first type of paging grouping manner and the second type of paging grouping manner.

[0228] The capability indication information indicates whether the UE supports the PEI corresponding to different types of paging groupings. The base station can determine the support capability of the UE for the PEI corresponding to different types of paging groupings, and then the base station can send the PEI corresponding to the paging grouping type of the UE to wake up the UE to monitor the PO, reduce the situation that the UE is woken up in the PO of other types of paging groupings, and reduce the power consumption of the UE caused by being woken up in invalid POs.

[0229] In one embodiment, the sending of the first capability indication information includes at least one of the following:

[0230] The first capability indication information indicating whether the UE supports the first type of PEI is sent to the base station;

[0231] 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;

[0232] 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.

[0233] 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.

[0234] 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.

[0235] 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.

[0236] 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.

[0237] When a UE is released from RRC connection state, it can carry capability indication information via uplink auxiliary messages.

[0238] 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.

[0239] 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.

[0240] like Figure 7 As shown in the exemplary embodiment, this method provides an information transmission method, the method further comprising:

[0241] Step 701: receiving second capability indication information from the base station, wherein the second capability indication information is used by the UE to determine the PEI that the base station is capable of sending.

[0242] Here, step 701 can be implemented alone or in combination with step 601.

[0243] The capability indication information can indicate the PEI that the base station is capable of sending. The UE can determine whether to monitor the PEI sent by the base station based on the PEI that the base station is capable of sending and the PEI that the UE itself supports.

[0244] For example, if the UE is capable of supporting the PEI sent by the base station, the UE can monitor the PEI. If the UE does not support the PEI sent by the base station, the UE can not monitor the PEI sent by the base station.

[0245] If the UE does not monitor the PEI of the base station, the UE can wake up and monitor the paging message at each PO.

[0246] The capability indication information can be carried in common signaling. For example, the capability indication information can be carried in a system message and broadcast to the UE.

[0247] The capability indication information can be carried in dedicated signaling. For example, the capability indication information can be carried in an RRC message and sent to the UE.

[0248] In one embodiment, the second capability indication information is used by the UE to determine that the base station is capable of sending at least one of:

[0249] The first type of PEI;

[0250] The second type of PEI corresponding to the first type of paging grouping mode, wherein the first type of PEI is different from the second type of PEI;

[0251] The second type of PEI corresponding to the second type of paging grouping mode;

[0252] The second type of PEI corresponding to the first type of paging grouping mode and the second type of paging grouping mode.

[0253] As shown in the example embodiment, the information transmission method further includes, Figure 8

[0254] Step 801: determining whether to monitor the PEI sent by the base station according to the PEI supported by the UE.

[0255] Here, step 801 can be implemented alone or in combination with step 601 and / or step 701.

[0256] ​The UE can determine whether to monitor the PEI sent by the base station based on its capability. If not, it can monitor the paging message in each PO according to the related art.

[0257] In one embodiment, the determining whether to monitor the PEI sent by the base station according to the PEI supported by the UE comprises at least one of:

[0258] monitoring the PEI sent by the base station in response to determining that the UE supports the PEI that the base station is capable of sending;

[0259] not monitoring the PEI sent by the base station in response to determining that the UE does not support the PEI that the base station is capable of sending.

[0260] If the UE supports the PEI sent by the base station, the UE can monitor the PEI and wake up in the PO based on the indication of the PEI. This reduces the case of waking up in each PO and saves the UE power consumption.

[0261] If the UE does not support the PEI sent by the base station, the UE monitors the paging message in each PO according to the related art. This reduces the case of missing the paging message.

[0262] In one embodiment, the monitoring the PEI sent by the base station in response to determining that the UE supports the PEI that the base station is capable of sending comprises at least one of:

[0263] monitoring the PEI sent by the base station in response to the base station being capable of sending a first type of PEI and the UE supporting the first type of PEI;

[0264] monitoring the PEI sent by the base station in response to the base station being capable of sending a second type of PEI and the UE supporting the second type of PEI.

[0265] For example, if the base station is capable of sending a first type of PEI, the UE supporting the first type of PEI can monitor the PEI and monitor the paging message based on the indication of the PEI.

[0266] For example, if the base station is capable of sending a first type of PEI, the UE not supporting the first type of PEI can not monitor the PEI and fall back to the legacy paging mode to wake up and monitor the paging message in each PO.

[0267] For example, if the base station is capable of sending a second type of PEI, the UE supporting the second type of PEI can monitor the PEI and monitor the paging message based on the indication of the PEI.

[0268] For example, if the base station is capable of sending the second type of PEI, the UE which does not support the second type of PEI can not monitor the PEI and fall back to legacy paging manner, i.e., wake up to monitor paging message at each PO.

[0269] In one embodiment, the UE determines whether to wake up at a PO based on the grouping information of the first type of paging grouping manner and / or the second type of paging grouping manner of itself, and the indication of the PEI.

[0270] For example, the PEI can indicate at least the paging grouping of the first type of paging grouping manner which needs to wake up, and the UE can determine whether the paging grouping of the first type of paging grouping manner of itself needs to wake up.

[0271] Alternatively,

[0272] The PEI can indicate at least the paging grouping of the second type of paging grouping manner which needs to wake up, and the UE can determine whether the paging grouping of the second type of paging grouping manner of itself needs to wake up.

[0273] In one embodiment, the monitoring the PEI sent by the base station in response to that the base station is capable of sending the first type of PEI and the UE supports the first type of PEI comprises at least one of:

[0274] monitoring the PEI sent by the base station in response to that the base station is capable of sending the first type of PEI and the UE supports the first type of PEI and the second type of PEI;

[0275] monitoring the PEI sent by the base station in response to that the base station is capable of sending the first type of PEI and the UE supports the second type of PEI.

[0276] The capability indication information indicating UE capability can indicate whether the UE supports PEI and the PEI corresponding to different paging grouping directions by explicit indication.

[0277] The capability indication information indicating UE capability indicates that the UE supports the first type of PEI and the second type of PEI, then when the base station is capable of sending the first type of PEI, the UE can monitor the PEI sent by the base station.

[0278] The capability indication information indicating UE capability indicates that the UE supports the second type of PEI, and the capability indication information can implicitly indicate that the UE also supports the first type of PEI. In this case, if the base station supports the first type of PEI, the UE can monitor the PEI sent by the base station.

[0279] In one embodiment, the UE monitors for the PEI transmitted by the base station in response to the base station being capable of transmitting the second type of PEI and the UE supporting the second type of PEI; including at least one of:

[0280] The UE monitors for the PEI transmitted by the base station in response to the base station being capable of transmitting the second type of PEI corresponding to at least a first type of paging group, and the UE supporting the second type of PEI corresponding to at least the first type of paging group.

[0281] The UE monitors for the PEI transmitted by the base station in response to the base station being capable of transmitting the second type of PEI corresponding to at least a second type of paging group, and the UE supporting the second type of PEI corresponding to at least the second type of paging group.

[0282] For example, if the base station is capable of transmitting the second type of PEI corresponding to the first type of paging group, then a UE supporting the second type of PEI corresponding to the first type of paging group can monitor for the PEI and monitor for paging messages based on the indication of the PEI.

[0283] For example, if the base station is capable of transmitting the second type of PEI corresponding to the first type of paging group, then a UE not supporting the second type of PEI corresponding to the first type of paging group can not monitor for the PEI and fall back to a legacy paging approach of waking up to monitor for paging messages at every PO.

[0284] For example, if the base station is capable of transmitting the second type of PEI corresponding to the second type of paging group, then a UE supporting the second type of PEI corresponding to the second type of paging group can monitor for the PEI and monitor for paging messages based on the indication of the PEI.

[0285] For example, if the base station is capable of transmitting the second type of PEI corresponding to the second type of paging group, then a UE not supporting the second type of PEI corresponding to the second type of paging group can not monitor for the PEI and fall back to a legacy paging approach of waking up to monitor for paging messages at every PO.

[0286] For example, if the base station is capable of transmitting the second type of PEI corresponding to the first type of paging group and the second type of paging group, then a UE supporting at least the second type of PEI corresponding to the first type of paging group or supporting at least the second type of PEI corresponding to the second type of paging group can monitor for the PEI and monitor for paging messages based on the indication of the PEI.

[0287] For example, if the base station is capable of sending the second type of PEI corresponding to the first type of paging group mode and the second type of paging group mode, and the UE supports at least the second type of PE corresponding to the first type of paging group mode and at least the second type of PE corresponding to the second type of paging group mode, the UE can monitor the PEI sent by the base station, and respectively use the group information of the first type of paging group mode of the UE and the group information of the second type of paging group mode of the UE to detect the PEI to determine whether the paging group corresponding to the group information of the first type of paging group mode or the paging group corresponding to the group information of the second type of paging group mode is to wake up at the PO. Here, the group information of the first type of paging group mode of the UE can be a group identifier allocated by the core network, and the group information of the first type of paging group mode of the UE can be a group identifier determined based on the UE_ID.

[0288] In one embodiment, in response to the base station being capable of sending the second type of PEI corresponding to at least the first type of paging group mode, the UE supporting at least the second type of PE corresponding to the first type of paging group mode, the UE monitors the PEI sent by the base station, including:

[0289] In response to the base station being capable of sending the second type of PEI corresponding to at least the first type of paging group mode, and the UE having the group information of the first type of paging group mode, the UE monitors the PEI sent by the base station.

[0290] For example, if the base station is capable of sending the second type of PEI corresponding to the first type of paging group mode, and the UE supporting the second type of PE corresponding to the first type of paging group mode, the UE can monitor the PEI sent by the base station only when the UE is configured with the group information of the first type of paging group mode, otherwise the UE does not monitor the PEI.

[0291] For example, if the base station is capable of sending the second type of PEI corresponding to the first type of paging group mode and the second type of paging group mode, and the UE only supports the second type of PE corresponding to the first type of paging group mode, the UE can monitor the PEI sent by the base station only when the UE is configured with the group information of the first type of paging group mode, otherwise the UE does not monitor the PEI.

[0292] For example, if the base station is capable of sending the second type of PEI corresponding to the first type of paging group mode and the second type of paging group mode, and the UE supports at least the second type of PE corresponding to the first type of paging group mode and at least the second type of PE corresponding to the second type of paging group mode, the UE can monitor the PEI sent by the base station, and respectively use the group information of the first type of paging group mode of the UE and the group information of the second type of paging group mode of the UE to detect the PEI to determine whether the paging group corresponding to the group information of the first type of paging group mode or the paging group corresponding to the group information of the second type of paging group mode is to wake up at the PO. Here, the group information of the first type of paging group mode of the UE can be a group identifier allocated by the core network, and the group information of the first type of paging group mode of the UE can be a group identifier determined based on the UE_ID.

[0293] As Figure 9As shown, the present exemplary embodiment provides an information transmission method, which can be executed by a core network of a cellular mobile communication system, comprising:

[0294] Step 901: receiving first capability indication information, wherein the first capability indication information indicates whether the UE supports PEI.

[0295] The PEI can be used to indicate that the UE wakes up and listens to a paging message in a predetermined paging occasion (PO). Here, the predetermined PO can include one or more POs after the PEI. Whether to support PEI can include, but not limited to, whether to support PEI-based indication to wake up in a predetermined PO.

[0296] The PEI can be used to wake up all UEs, or can be used to wake up UEs in a predetermined range (such as a predetermined group, a predetermined type, etc.). The PEI can contain indication information for different groups of UEs, for waking up different groups of UEs. Whether to support PEI can include, but not limited to, whether to support PEI to wake up all UEs, and / or whether to support PEI to wake up UEs in a predetermined range.

[0297] In addition to carrying paging information, the PEI can also be used as an extension to carry other information subsequently.

[0298] The capability indication information can be reported by the base station to the core network, or can be sent by the UE to the core network. The UE can also carry the capability indication information through NAS signaling, etc.

[0299] 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 PEI supported by the UE to wake up the UE to listen to the PO. Thus, it reduces the case that the core network cannot determine whether the UE supports PEI, and sends PEI to the UE when the UE does not support PEI, or does not send PEI to the UE when the UE supports PEI. Sending PEI to the UE when the UE does not support PEI will increase the workload of the core network; and when the UE supports PEI, the UE needs to wake up frequently to listen to the PO due to the inability to receive PEI, resulting in power consumption of the UE.

[0300] In this way, the capability indication information indicates whether the UE supports PEI. The core network can determine the PEI capability of the UE, reduce the misjudgment of the UE's capability due to the uncertainty of the core network's PEI capability, and improve the accuracy of the core network's judgment of the UE's PEI capability.

[0301] In one embodiment, the first capability indication information is used to indicate at least one of the following:

[0302] Whether the UE supports the first type of PEI;

[0303] whether the UE supports a second type of PEI, wherein the first type of PEI is different from the second type of PEI.

[0304] The first type of PEI can have 1 bit to indicate whether the UE is to wake up or not, i.e., PEI without a paging packet

[0305] The first type of PEI can also be extended for use other than paging in the future.

[0306] In summary, the first type of PEI is supported, i.e., the terminal has the capability to monitor the PEI signal, which can carry paging or other information.

[0307] The second type of PEI can have multiple bits to indicate whether the UE is to wake up or not, i.e., PEI with a paging packet

[0308] The second type of PEI can be a subset of the first type of PEI.

[0309] In one embodiment, the first type of PEI is a common PEI or a non-packet PEI, which can be used to wake up all UEs that need to monitor the same PO or all UEs of a group;

[0310] In one embodiment, the second type of PEI is a PEI for a paging group, which can be used to wake up all UEs that monitor the same PO corresponding to the paging group according to the paging group.

[0311] When the PEI has 1 bit, i.e., the PEI is the first type of PEI, the PEI can be used to wake up all UEs that receive the PEI. That is, the first type of PEI does not distinguish the paging group of the UE.

[0312] When the PEI has multiple bits, i.e., the PEI is the second type of PEI, each bit of the multiple bits can be used to wake up one or more paging groups of UEs. That is, the second type of PEI distinguishes the paging group of the UE.

[0313] For example, the PEI can include POnumPerPEI segments, which can be referred to as a subgroupsNumPerPO field. Each segment can correspond to a PO. Each segment contains subgroupsNumPerPO bits, and each bit carries a paging indication to indicate whether 1 or more paging groups are to wake up in the corresponding PO.

[0314] The PEI is a first type of PEI, the subgroupsNumPerPO field has one bit of paging indication bit, and all UEs receiving the PEI are woken up to listen to a paging message in a PO. For example, when the paging indication bit is "1", all UEs receiving the PEI are woken up to listen to a paging message in a PO period, and when the paging indication bit field is "0", it indicates that the UE remains in a sleep state in the PO period, such as remaining in an RRC idle state or an RRC inactive state.

[0315] The PEI is a second type of PEI, the subgroupsNumPerPO field has multiple bits, each bit can correspond to a paging group, and UEs of different paging groups determine whether to wake up in a PO period based on the bit corresponding to their own paging group. For example, the subgroupsNumPerPO field has two bits corresponding to two paging groups, when one of the bits is "1", the UE of the paging group corresponding to the bit is woken up to listen to a paging message in a PO, and when one of the bits is "0", it indicates that the UE of the paging group corresponding to the bit remains in a sleep state in the PO.

[0316] The capability indication information can be used to indicate whether the UE supports the first type of PEI and / or the second type of PEI.

[0317] If the capability indication information indicates that the UE supports the first type of PEI, the base station can use the first type of PEI to wake up the UE to listen to the PO. Reducing the case that the UE needs to wake up in each PO, reducing the power consumption of the UE.

[0318] If the capability indication information indicates that the UE supports the second type of PEI, the base station can use the second type of PEI to wake up the UE to listen to the PO based on the paging group. Reducing the case that the UE is woken up in the PO when the paging group is not paged, reducing the power consumption of the UE.

[0319] In this way, the capability indication information indicates whether the UE supports the PEI. The base station can determine the PEI capability of the UE, and then send the PEI supported by the UE to wake up the UE to listen to the PO based on the PEI capability of the UE, without waking up the UE to listen when the UE does not need to be woken up, reducing the power consumption caused by frequent waking up of the UE.

[0320] In one embodiment, whether the UE supports the second type of PEI includes at least one of:

[0321] Whether the UE supports the second type of PEI corresponding to at least the first type of paging group mode;

[0322] Whether the UE supports the second type of PEI corresponding to at least the second type of paging group mode.

[0323] The first type of paging grouping manner and the second type of paging grouping manner divide paging groups in different ways. The first type of paging grouping manner and the second type of paging manner can also be performed by different network nodes. The first type of paging grouping and the second type of paging can also be performed by the same network node.

[0324] The core network or the base station, etc. can divide paging groups in different paging grouping manners respectively, thereby generating different types of paging groups. Each paging grouping manner can divide a plurality of paging groups respectively. For example, grouping can be performed based on the service type of the UE, or grouping can be performed based on the transmission rate of the UE, etc.

[0325] The second type of PEI corresponding to at least the first type of paging grouping manner can be used to indicate at least whether the UE of the paging group corresponding to the first type of paging grouping manner wakes up.

[0326] The second type of PEI corresponding to at least the second type of paging grouping manner can be used to indicate at least whether the UE of the paging group corresponding to the second type of paging grouping manner wakes up.

[0327] In one embodiment, the first type of paging grouping manner includes: a paging grouping manner of determining a paging group by a core network;

[0328] The second type of paging grouping manner includes: a paging grouping manner of determining a paging group based on UE identification.

[0329] The first type of paging grouping manner can be a manner of dividing paging groups by the core network based on UE attributes. Here, the UE attributes can include but are not limited to: the service type of the UE, the transmission quantity of the UE, the transmission bandwidth of the UE, etc.

[0330] The second type of paging grouping manner can be a manner of dividing paging groups by the base station based on UE identification information (UE-ID). For example, the base station can determine the paging group of the UE using expression (1)

[0331] Each bit of the plurality of bits of the second type of PEI can be used to indicate whether one or more paging groups wake up within a predetermined PO. Here, the paging groups can include: paging groups divided by the first type of paging grouping manner, or paging groups divided by the second type of paging grouping manner.

[0332] For example, the second type of PEI can have 8 bits, wherein each of the 4 bits is used to indicate one of the 4 paging groups divided by the first type of paging grouping manner, and each of the other 4 bits is used to indicate one of the 4 paging groups divided by the second type of paging grouping manner.

[0333] The second type PEI corresponding to at least the first type paging grouping manner can include the second type PEI corresponding to only the first type paging grouping manner, or can include the second type PEI corresponding to both the first type paging grouping manner and the second type paging grouping manner.

[0334] The second type PEI corresponding to at least the second type paging grouping manner can include the second type PEI corresponding to only the second type paging grouping manner, or can include the second type PEI corresponding to both the first type paging grouping manner and the second type paging grouping manner.

[0335] The capability indication information indicates whether the UE supports the PEI corresponding to different types of paging grouping. The base station can determine the support capability of the UE for the PEI corresponding to different paging grouping types, and then the base station can send the PEI corresponding to the paging grouping type of the UE to wake up the UE to monitor the PO, reduce the case that the UE is woken up in the PO of other types of paging grouping, and reduce the power consumption of the UE caused by being woken up in invalid PO.

[0336] In an embodiment, the receiving the first capability indication information includes at least one of:

[0337] The first capability indication information indicating whether the UE supports the second type PEI corresponding to at least the first type paging grouping manner is received from the UE;

[0338] The first capability indication information indicating whether the UE supports the first type PEI is received from the base station;

[0339] The first capability indication information indicating whether the UE supports the second type PEI corresponding to at least the second type paging grouping manner is received from the base station.

[0340] The capability indication information can be sent by the UE to the core network. For example, the UE can carry the capability indication information through NAS signaling.

[0341] For example, whether the UE supports the second type PEI corresponding to at least the first type paging grouping manner can be reported by the UE to the core network through NAS signaling, and therefore the capability indication information sent by the core network to the base station can also indicate whether the UE supports the second type PEI corresponding to at least the first type paging grouping manner.

[0342] For example, whether the terminal supports the second type PEI corresponding to at least the first type paging grouping manner is determined by the base station based on the capability indication information sent by the core network through explicit indication.

[0343] The base station can report the UE's capability to the core network after receiving the capability indication information reported by the UE. The capability indication information reported by the UE can be used to indicate whether the UE supports the first type of PEI and / or whether the UE supports the second type of PEI corresponding to at least the second type of paging grouping manner. Therefore, the capability indication information sent by the base station can also be used to indicate whether the UE supports the first type of PEI and / or whether the UE supports the second type of PEI corresponding to at least the second type of paging grouping manner.

[0344] For example, the UE reports the capability of supporting PEI to the base station through the capability indication information, and the base station reports the capability to the core network through the capability indication information. The capability indication information can indicate whether the UE supports the first type of PEI and / or whether the UE supports the second type of PEI corresponding to at least the second type of paging grouping manner. Whether the UE supports the second type of PEI corresponding to at least the first type of paging grouping manner is transmitted by the terminal to the core network through NAS signaling, and therefore the base station does not need to report.

[0345] For example, the capability indication information can be carried in the following messages:

[0346] UE CAPABILITY INFO INDICATION;

[0347] RRC INACTIVE TRANSITION REPORT.

[0348] As shown in Figure 10 , the present example embodiment provides an information transmission method, and the method further includes at least one of:

[0349] Step 1001a: sending second UE capability indication information indicating whether the UE supports the first type of PEI to the base station;

[0350] Step 1001b: sending second UE capability indication information indicating whether the UE supports the second type of PEI to the base station.

[0351] Here, step 1001a and / or step 1001b can be implemented alone or in combination with step 901.

[0352] The capability indication information can also be sent by the core network to the base station, and the capability indication information indicates whether the UE supports the first type of PEI and whether the UE supports the second type of PEI corresponding to at least the second type of paging grouping manner.

[0353] Whether the UE supports the second type of PEI corresponding to at least the first type of paging grouping manner can be reported by the UE to the core network through NAS signaling, and therefore, the capability indication information sent by the core network to the base station can also indicate whether the UE supports the second type of PEI corresponding to at least the first type of paging grouping manner.

[0354] For example, whether the terminal supports the second type of PEI corresponding to at least the first type of paging grouping manner is determined by the base station based on the capability indication information sent by the core network.

[0355] The capability of the UE can also be transmitted between base stations. The capability indication information can be sent by the opposite base station.

[0356] The following provides a specific example in combination with any of the above embodiments:

[0357] 1. A method for a base station to obtain the support capability of a terminal for a paging early indication (PEI);

[0358] 2. The base station learns whether the UE supports the paging grouping scheme capability from the capability indication information reported by the terminal;

[0359] a) The information is used by the network as a reference for paging grouping;

[0360] b) As an embodiment, the paging grouping scheme capability can be the capability of the terminal reporting that it supports the UE-ID paging grouping scheme; here, the capability of supporting the UE-ID paging grouping scheme means that the terminal supports the second type of PEI corresponding to the second type of paging grouping described above. (The terminal is: a capability 2 type terminal)

[0361] c) As an embodiment, the paging grouping scheme capability can be the capability of the terminal reporting that it supports the PEI scheme; here, the capability of supporting the PEI means that the terminal supports the first type of PEI described above. (The terminal is: a capability 1 type terminal). If the first type of PEI is used to carry the non-grouped PEI, it includes the capability of supporting the non-grouped PEI.

[0362] Signaling design form:

[0363] Capabiltiy1-PEI ENUMERATED {true} OPTIONAL,

[0364] Capabiltiy2-UEID-subgrouping ENUMERATED {true} OPTIONAL,

[0365] Furthermore, there are multiple ways to classify terminal capabilities:

[0366] 1) Method 1

[0367] There is no correlation between the multiple capabilities;

[0368] The terminal reporting capability 1 supports PEI monitoring;

[0369] The terminal reporting capability 2 supports PEI group paging monitoring;

[0370] That is, the two capabilities are reported independently.

[0371] 2) Mode 2

[0372] The support of capability 2 implies the support of capability 1, that is, capability 2 is a subset of capability 1. The terminal can further indicate the support of capability 2 on the basis of reporting capability 1 as (true)ture; (at this time, the two types of terminals can be collectively referred to as PEI-capable terminals).

[0373] The terminal can only report the support of capability 1; (capability 2 is not supported).

[0374] The terminal can report the support of capability 1 and the support of capability 2 at the same time; that is, both flag (true) are reported.

[0375] The terminal can report the support of capability 1 and the non-support of capability 2 at the same time; it can be expressed that only capability 1 is supported by not reporting the flag, that is, the non-support of capability 2 is implicitly expressed by the absence of the flag.

[0376] The terminal can only report the support of capability 2; the implicit expression of reporting the support of capability 2 is that the terminal also supports capability 1.

[0377] 2) Mode 3

[0378] The terminal only reports the capability (capability 2) of supporting the UE-ID paging grouping scheme to the base station;

[0379] The base station obtains from the core network whether the terminal supports the core network paging grouping scheme; that is, whether the terminal has capability 3 is obtained from the core network, and the base station combines the two ways to obtain the capability of the terminal; here, the capability of supporting the core network paging grouping scheme, that is, the terminal supports the second type of PEI corresponding to the first type of paging grouping.

[0380] The base station obtains that the terminal supports the UE-ID paging grouping scheme (capability 2) or the core network paging grouping scheme (capability 3), that is, at least one of them is supported, then the PEI is supported, that is, the capability 1 of the terminal is supported. At this time, the capability of supporting PEI is implicitly expressed by the terminal supporting the UE-ID paging grouping scheme (capability 2) or supporting the core network paging grouping scheme (capability 3). That is, if the UE-ID paging grouping scheme or the core network paging grouping scheme is supported, it is expressed that the terminal supports PEI.

[0381] The base station acquires that the terminal does not support the UE-ID paging grouping scheme (capability 2) and does not support the paging grouping scheme of the core network (capability 3), that is, neither of the two is supported, and thus does not support PEI, that is, the terminal does not support capability 1.

[0382] For ease of understanding, the reason why whether the terminal supports PEI is expressed by whether the terminal supports the paging grouping scheme is that, in the R17 version, the paging grouping information is only sent by using PEI. PEI is currently mainly used to bear the paging grouping information.

[0383] For example, the base station acquires that the terminal supports the UE-ID paging grouping scheme, which can be that the base station carries support in the received capability indication information reported by the UE;

[0384] For example, the base station acquires that the terminal does not support the UE-ID paging grouping scheme, which can be that the base station carries non-support in the received capability indication information reported by the UE, or does not receive the reporting indication.

[0385] The base station acquires that the terminal supports the core network paging grouping scheme capability (capability 3) can be that the base station obtains the grouping ID from the core network; the core network allocates the grouping ID for the user, and thus determines that the terminal must have the capability of supporting the core network paging grouping scheme; this is an implicit indication.

[0386] The base station acquires that the terminal supports the core network paging grouping scheme capability (capability 3) can be that the base station obtains the explicit indication of support or non-support from the core network; that is, using a display indication bit to indicate whether support is supported.

[0387] 3. The terminal reports the capability to the base station.

[0388] 1) Through the existing UE capability reporting;

[0389] 2) Through uplink assistant information (UAI, Uplink Assistant Info) reporting;

[0390] As an embodiment, the UE can report the assistant information when it is expected to leave the connected state, and the reference assistant information of the paging grouping is only useful when the terminal leaves the connected state.

[0391] 4. The reporting capability of the terminal can be transmitted between the core network and the base station;

[0392] a) For example, the terminal reports the capability including capability 1 and capability 2;

[0393] b) As an embodiment: UE capability is reported to the base station, and the base station informs the core network (capability 1 or capability 2) through the UE CAPABILITY INFO INDICATION; capability 3 is delivered to the core network by the terminal through NAS, so it is not necessary to report directly to the base station.

[0394] The UE capability can also be reported to the base station through the following messages:

[0395] RRC INACTIVE TRANSITION REPORT.

[0396] c) As an embodiment: the core network delivers to the base station in the paging message;

[0397] Display mode: UE capability information (capability 1 and / or capability 2 or capability 3) is carried in the paging message, wherein capability 3 is delivered to the core network by the terminal through NAS.

[0398] Capability 3 can be indicated in an explicit and implicit manner.

[0399] Implicit indication means that the paging message mentioned above carries the paging group information allocated by the core network, which means that the terminal has capability 3.

[0400] d) As an embodiment: the core network delivers the UE capability to the base station in the following messages.

[0401] INITIAL CONTEXT SETUP REQUEST;

[0402] UE CONTEXT MODIFICATION REQUEST;

[0403] HANDOVER REQUEST;

[0404] PATH SWITCH REQUEST ACKNOWLEDGE;

[0405] 5. Based on 1; the terminal's capability: capability 1 and / or capability 2, and whether the terminal supports the core network's paging group scheme (capability 3) can be delivered between base stations;

[0406] Scenario 1: When handover occurs, the base station obtains the terminal's capability from the handover request message;

[0407] Scenario 2: When cell reselection occurs for the non-active state user, the base station obtains the terminal's capability from the anchor base station;

[0408] a) As an embodiment, the UE context response can carry the terminal's capability;

[0409] b) As an embodiment, the indication information of UE capability is carried in the access network paging (RAN Paging) message;

[0410] The target base station (opposite end base station) can directly acquire capability 1;

[0411] The target base station can directly acquire capability 2;

[0412] The target base station can directly acquire capability 3;

[0413] The target base station can directly acquire capability 2 or capability 3 support to know the support of capability 1;

[0414] The target base station can directly acquire the non-support of capability 2 and the non-support of capability 3 to infer the non-support of capability 1;

[0415] The core network group ID carried is implicitly expressed as the terminal supporting capability 3.

[0416] 6. The terminal core network decides the following behaviors according to the terminal capability and the paging scheme support capability of the base station:

[0417] a) The paging scheme support capability of the base station will be notified to the UE through public or private signaling;

[0418] b) The terminal with PEI support capability will listen to the PEI according to the base station capability and its own capability to listen to the PEI or paging message; (There are capability 1 terminals, capability 2 terminals, capability 3 terminals, and terminals with both capability 2 and capability 3 in the network)

[0419] The base station capability is divided into the following two types: the first type of base station capability and the second type of base station capability:

[0420] Case 1:

[0421] The base station sends non-group PEI: the support capability 1 terminal, the support capability 2 terminal, the support capability 3 terminal and the terminal with both capability 2 and capability 3 need to be woken up by listening to the PEI;

[0422] Only the terminal supporting capability 1 supports this type of PEI, at this time, the PEI will be used for paging message listening (i.e. woken up by the PEI);

[0423] Or the terminal supporting capability 2 and / or 3 supports this type of PEI, at this time, the PEI will be used for paging message listening (i.e. woken up by the PEI).

[0424] Listen to paging message with PEI, i.e. listen to the following PO according to the indication of PEI; not listen to paging message according to PEI, i.e. not listen to the following PO according to the indication of PEI, i.e. directly listen to PO, i.e. the traditional (Legacy) paging listening mode.

[0425] The terminal reporting support capability 1 will support this type of PEI, at which time the terminal listens to the paging message with PEI (i.e. is woken up by the PEI);

[0426] Or the terminal supporting capability 2 / 3 further on the basis of supporting capability 1 supports this type of PEI, at which time the terminal also listens to the paging message with PEI (i.e. is woken up by the PEI);

[0427] The terminal supporting capability 2 or capability 3 learns to support capability 1 and listens to the paging message with PEI (i.e. is woken up by the PEI);

[0428] The terminal not supporting capability 2 and not supporting capability 3 infers that the terminal does not support capability 1, at which time the terminal falls back to the legacy paging mode.

[0429] Case 2:

[0430] The base station sends a group PEI: the base station capability is divided into downlink core network group PEI, UE-ID group PEI, or simultaneously supports core network group PEI and UE-ID group PEI, 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.

[0431] A. Only support capability 1 type users will not be able to support this type of PEI, at which time the terminal cannot listen to the paging message with the group PEI; i.e. the user can only return to the traditional (Legacy) listening mode (i.e. no need for PEI listening);

[0432] How to determine that the terminal only supports capability 1 can be discussed in different cases:

[0433] 1) Method 1, i.e. only supporting capability 1 is reported separately;

[0434] 2) Method 2: only supporting capability 1 is reported according to the above description;

[0435] 3) Method 3: the terminal does not support capability 2 and capability 3.

[0436] The terminal with paging grouping capability (the terminal supporting capability 2 or capability 3) will listen to the PEI: specifically:

[0437] B. For the base station supporting only the UE-ID grouping mode (the second type of base station capability):

[0438] The terminal supporting capability 2 can monitor the paging message by using the group PEI (regardless of whether the group ID is assigned by the core network); and it is required to check whether the group to which the terminal belongs is woken up;

[0439] The terminal user not supporting the UE-id grouping mode, such as the UE capability 3 terminal, cannot support the PEI of this type, and thus cannot monitor the paging message by using the group PEI; that is, the user can only return to the legacy monitoring mode (i.e., no need to monitor the PEI);

[0440] C. For the base station supporting only the CN-assigned grouping mode (the third type of base station capability):

[0441] The terminal supporting capability 3 can monitor the paging message by using the group PEI; and the terminal not supporting capability 3 does not monitor the PEI;

[0442] Furthermore, the user assigned only with the group ID by the core network needs to check whether the group to which the user belongs is woken up; and the user not assigned does not need to monitor the PEI; because the user not assigned with the group ID by the core network, even if having the capability supporting capability 3, does not need to monitor the PEI, which plays a role in simplifying the process and saving power.

[0443] The terminal supporting only capability 2 (i.e., the terminal supporting only the UE-id grouping mode, but not supporting the CN grouping capability) cannot support the PEI of this type, and thus cannot monitor the paging message by using the group PEI; that is, the user can only return to the legacy monitoring mode (i.e., no need to monitor the PEI);

[0444] In this way, when the terminal obtains the capability of the base station, and finds that the type of the paging PEI issued by the base station does not match the support capability of the terminal, the terminal does not need to monitor the PEI, which plays a role in simplifying the process and saving power.

[0445] D. For the base station supporting the CN-assigned grouping mode + the UE-ID grouping mode (the fourth type of base station capability):

[0446] The terminal user supporting the UE-id grouping mode or supporting the CN grouping mode monitors the paging message by using the group PEI; and it is required to check whether the group to which the terminal belongs is woken up;

[0447] Furthermore, the user assigned only with the group ID by the core network needs to check whether the group to which the user belongs is woken up; and the user not assigned needs to monitor the PEI if having capability 2; otherwise, the user does not need to monitor the PEI.
