[0162] Table 1 is a mapping relationship table between paging feature types and paging resources provided in an embodiment of the present application. As shown in Table 1, the base station configures two paging feature categories, mobility category and coverage type category. For example, in the case where the paging feature type is a stationary terminal, the paging resource corresponding to index #0. In the case where the paging feature type is a terminal supporting enhanced coverage, the paging resource corresponding to index #3.

[0169] In an application example, a method for negotiating and determining a paging characteristic type is provided.

[0170] For the classification method based on the purpose of the terminal, the terminal side and the base station side must have the same understanding of the terminal's paging feature category. First, the terminal and the network side must negotiate to determine the terminal category. The network side can be understood as the core network (Access and Mobility Management Function, AMF).

[0171] The UE and AMF negotiate through NAS messages to determine the UE paging feature type. The NAS message includes at least: Registration request message.

[0172] There are two main ways for the UE and AMF to negotiate and determine the UE paging feature type.

[0173] In the first method, the UE informs the AMF of the paging feature type and the AMF confirms it. Figure 4 is a flow chart of a paging feature type negotiation method provided in an embodiment of the present application, such as Figure 4 As shown, the paging characteristic type negotiation method mainly includes steps S41, S42, and S43.

[0174] S41. The UE sends a registration request message to the AMF, wherein the registration request message carries information related to paging characteristics.

[0175] S42. AMF sends a registration confirmation (Registration Accept) message to the UE, wherein the registration confirmation message carries paging feature type confirmation information.

[0176] S43. UE sends a Registration Complete message to AMF.

[0177] In the second method, the AMF identifies the paging feature type of the UE, notifies the UE, and the UE confirms. Figure 5 is a flow chart of a paging feature type negotiation method provided in an embodiment of the present application, such as Figure 5 As shown, the paging characteristic type negotiation method mainly includes steps S41, S42, and S43.

[0178] S51. UE sends a registration request message to AMF.

[0179] S52. AMF sends a registration confirmation (Registration Accept) message to the UE, wherein the registration request message carries information related to paging characteristics.

[0180] S53. The UE sends a registration complete message to the AMF, wherein the registration complete message carries paging feature type confirmation information.

[0181] Furthermore, the content negotiated between the UE and the AMF includes the following two forms:

[0182] The first is that if the paging feature type has been predefined in the system, the predefined form means defining a corresponding paging feature index for each paging feature type. Table 3 is a table of correspondence between paging feature types and paging feature indexes provided in an embodiment of the present application. As shown in Table 3, the paging feature type corresponding to paging feature index 0 is a large data packet; the paging feature type corresponding to paging feature index 1 is a small data packet. It should be noted that Table 3 is only an exemplary description of the correspondence between paging feature types and paging feature indexes, and is not a limitation.

[0185] In this case, the UE and AMF may negotiate the content of the paging feature type or directly negotiate the paging-related feature index; the base station broadcasts the configuration information corresponding to each paging feature index.

[0186] The second is that the UE negotiates with the AMF on specific paging-related feature types. In this case, the base station needs to broadcast the configuration information corresponding to each paging feature type.

[0187] In an application example, an embodiment of the present application provides a method for a base station to page a UE. The base station configures paging resources through SIB based on the UE paging characteristic type, a certain UE paging characteristic type is transmitted to the base station and / or core network through AS signaling, and subsequent paging is based on the UE paging characteristic type.

[0188] Figure 6 1 is a flow chart of a paging method provided by an embodiment of the present application. Figure 6 As shown, the paging method provided in the embodiment of the present application mainly includes the following steps:

[0189] S61. The base station configures paging resources based on the UE paging characteristic type.

[0190] The paging resource includes at least one of the following:

[0191] Different paging monitoring intervals (drxCycle) are configured for UEs with different paging characteristics, different maximum paging PDCCH repetition times are configured for UEs with different paging characteristics, different wake-up service (WUS) resources are configured for UEs with different paging characteristics, and different carrier resources are configured for UEs with different paging characteristics.

[0192] For example: WUS resources specially configured for stationary UEs, a larger paging monitoring interval (drxCycle) specially configured for delay-insensitive UEs, a smaller maximum number of paging physical downlink control channel (PDCCH) repetitions specially configured for UEs with low paging reliability requirements; a smaller maximum number of paging PDCCH repetitions specially configured for UEs with lower power levels (lower uplink maximum transmit power).

[0193] S62. The base station sends the paging resources configured based on the paging feature type to the UE through a broadcast message (SIB).

[0194] S63. The UE sends the paging characteristic type of the UE to the base station through an AS message or a MAC CE message.

[0195] The AS message may be: UE downlink capability information, or other uplink RRC messages, wherein the UE-RadioPagingInfo information element is carried by UE CapabilityInformation.

[0196] The paging characteristics include at least one of the following: UE power level indication, low power level UE indication, UE paging reliability requirement is not high (paging monitoring relaxation indication), stationary UE indication, slow moving UE indication, UE moving trajectory (historical cell range), UE moving direction and moving speed, and UE carried service type.

[0197] S64. The base station sends the UE's paging characteristic type (eg, UE-RadioPagingInfo information element) to the core network through UE-specific signaling.

[0198] S65. The core network sends the paging characteristic type of the UE to the base station through a Paging message.

[0199] The paging feature type of the UE carried in the Paging message sent by the core network to the base station may be carried by the UE Radio Capability for Paging information element in the Paging message (the UE Radio Paging Information message included therein further includes the UE-RadioPagingInfo information element).

[0200] It should be noted that the base station may also store the paging characteristic type of the UE. In the case where the base station stores the paging characteristic type of the UE, S64 and S65 may be omitted.

[0201] S66: The base station matches the paging characteristic-related information of the UE with the paging-related resources configured by the base station based on the paging characteristic of the UE, and selects the paging resources corresponding to the paging characteristic of the UE to send a paging message.

[0202] The UE matches the paging characteristic type of the UE with the paging resources configured by the base station based on the paging characteristic type of the UE, and selects the paging resources corresponding to the paging characteristic of the UE to monitor the paging message.

[0203] For example: a stationary UE selects the WUS resource configured for the stationary UE; a delay-insensitive UE selects a larger paging monitoring interval (drxCycle) configured specifically for the delay-insensitive UE; a UE with low paging reliability requirements selects a smaller paging PDCCH maximum repetition number configured specifically for the UE with low paging reliability requirements.

[0204] Furthermore, whether the UE is stationary can also be determined by whether the cell where the UE is currently paging is consistent with the cell where the UE was paging when the RRC connection was released or suspended last time.

[0205] In an application example, an embodiment of the present application also provides a method for a gNB to obtain a UE paging characteristic type. Figure 7 This is a flowchart of a method for a gNB to obtain a UE paging characteristic type provided in an embodiment of the present application, such as Figure 7 As shown, the steps of the method for gNB to obtain the UE paging characteristic type provided in the embodiment of the present application mainly include:

[0206] S71. When paging the UE, the AMF sends a paging message (paging) to the gNB, wherein the paging message carries the paging feature type of the UE.

[0207] The UE paging feature types include:

[0208] Classification is based on network quality of service (QoS), which includes one or more of the following: data packets, maximum bit rate, resource allocation reservation priority, and data packet error rate.

[0209] For example, according to the size of the data packet, it can be divided into large data packets, small data packets, etc. Another example is that according to the data transmission rate, it can be divided into high transmission rate, low transmission rate, etc. Another example is that according to the reliability, it can be divided into high reliability, low reliability, etc.

[0210] Classification is carried out according to the terminal access network type. The access network type includes one or more of the following: access to the new air interface NR network, access to the new air interface NR low complexity network.

[0211] For example, it can be divided into terminals accessing NR network, terminals accessing NR low-complexity network, etc.

[0212] The form may be an indication of a certain type or UE id value information carrying this type of terminal, for example, NR UE Identity Index value, NR Light UE Identity Index value.

[0213] The terminals are classified according to their mobility, which includes one or more of the following: stationary, high-speed moving, and low-speed moving.

[0214] For example, the terminals can be classified into local cell terminals, non-local cell terminals, etc. according to their mobility; the paging message sent by the core network carries the cell identifier information.

[0215] Classified according to coverage type, the coverage type includes one or more of the following: normal coverage, enhanced coverage, and enhanced coverage level.

[0216] For example, coverage types can be classified into normal coverage, enhanced coverage, etc.

[0217] Furthermore, for enhanced coverage, different coverage levels are classified. The configuration method of paging resources under this classification includes the following information in addition to the paging resource configuration content of other classifications:

[0218] Based on the coverage type, such as common coverage and enhanced coverage, the corresponding paging carrier is configured; the corresponding paging carrier is configured according to different coverage levels, and the corresponding paging PDCCH repetition times are configured.

[0219] Classified according to power consumption, the power consumption includes one or more of the following: low power consumption, high power consumption.

[0220] For example, according to power consumption, it can be divided into low power consumption, high power consumption, etc.

[0221] Furthermore, the base station determines the paging control resource set used for paging the terminal according to the paging control resource set information configured for each paging feature type and the paging feature type carried by the AMF.

[0222] The terminal determines the paging control resource set for monitoring the paging message according to the paging control resource set information configured for each paging feature type broadcasted by the base station in the system message and the paging feature type determined by the terminal through negotiation.

[0223] In addition, the embodiment of the present application also provides a method for gNB to obtain the paging feature type in the cell. AMF can also bring the paging feature type in the cell to the gNB through the public signaling of the NG interface (such as NG Setup Response, RAN Configuration UpdateAcknowledge, AMF Configuration Update).

[0224] Figure 8 This is a flowchart of a method for a gNB to obtain a paging feature type within a cell provided in an embodiment of the present application, such as Figure 8 As shown, the steps of the method for gNB to obtain the paging characteristic type in the cell provided in the embodiment of the present application mainly include:

[0225] S81. gNB sends an NG Setup Request message to AMF.

[0226] S82. AMF sends an NG interface confirmation (NG Setup Response), wherein the NG Setup Response message carries the paging feature type in the cell.

[0227] Furthermore, the gNB configures paging resources corresponding to each paging feature type in the cell accordingly, such as configuring one or more paging control resource sets for one or more paging categories, or configuring one or more paging control resource sets for one or more paging categories.

[0228] Furthermore, Fig. 9 is a flowchart of a method for broadcasting a configuration message of a gNB provided in an embodiment of the present application, such as Fig. 9 As shown, the steps of the gNB broadcast configuration message method provided in the embodiment of the present application mainly include:

[0229] S91. The gNB broadcasts the paging resources configured by the paging feature type to the UE.

[0230] In an application example, the terminals are classified according to their mobility. The local cell terminals are those that are still in the cell when the previous connection is released, and the non-local cell terminals are those that have moved out of the cell when the previous connection is released and are in other cells.

[0231] Furthermore, when releasing the connection, the base station informs the core network of the cell ID information to which the terminal is connected.

[0232] During subsequent paging, the core network carries the cell ID information to which the terminal last connected in the paging message.

[0233] Specifically, according to the mobility classification, when releasing the connection, the base station informs the network side of the cell ID information to which the UE is connected in the UE Context ReleaseComplete message.

[0234] Fig.10 1 is a flowchart of the interaction between the base station and the AMF when releasing the connection provided in the embodiment of the present application. Fig.10 As shown, the protection process between the base station and the AMF when releasing the connection provided in the embodiment of the present application mainly includes the following steps:

[0235] S101. gNB sends a UE Context Release Request message to AMF.

[0236] S102. AMF sends a UE Context Release Command message to gNB.

[0237] S103. The gNB sends a UE Context Release Complete message to the AMF. The UE Context Release Complete message carries a cell code (Cell id).

[0238] Furthermore, according to the mobility classification, the core network needs to carry the cell ID information when sending a paging message. If the cell ID belongs to the base station, the base station will page the UE on the configured paging resources of the cell terminal, otherwise it will page the UE on the configured paging resources of non-cell terminals.

[0239] Fig.11 is a flowchart of a method for a base station to obtain a paging characteristic type provided by an embodiment of the present application, such as Fig.11 As shown, the method for a base station to obtain a paging characteristic type provided in an embodiment of the present application mainly includes the following steps:
