Description

Technical Field

[0001] This application relates to the field of wireless communication technology, and in particular to a paging method, network-side device, and terminal. Background Technology

[0002] With the rapid development of technology, users' demands for communication are also increasing. Satellite base stations based on the New Radio (NR) Non-Terrestrial Network (NTN) standard support on-board regeneration mode.

[0003] In the existing technology, after a user equipment (UE) registers, the core network assigns a list of tracing area identities (TAIs) to the UE. In order to ensure that the UE can accurately detect leaving the TAI list and trigger the registration domain update process, the coverage of the TAI list assigned to the UE must be greater than or equal to the coverage of the satellite serving cell. Therefore, when the core network pages the UE, it needs to page within at least one satellite serving cell.

[0004] Because the coverage area of ​​a satellite-based serving cell is very large, a satellite-based serving cell is usually divided into many beams. Due to the limited radio frequency capabilities and power consumption of the satellite-based base station, and the limited number of active beams, the current paging method usually needs to poll between multiple beams to send public messages such as broadcasts or paging, resulting in low paging efficiency and prolonged paging time. Summary of the Invention

[0005] This application provides a paging method, network-side device, and terminal for sending the association between TAI and waveform information to the UE, performing fast paging based on the waveform information, thereby improving paging efficiency, shortening paging latency, and improving user experience.

[0161] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. The character " / " generally indicates that the preceding and following associated objects have an "or" relationship.

Those skilled in the art will understand that with the emergence of new application scenarios, the technical solutions provided in this application are also applicable to similar technical problems. In the description of this application, unless otherwise stated, "multiple" means two or more.

[0164] Before introducing the paging method provided in the embodiments of this application, for ease of understanding, the technical background of the embodiments of this application will be described in detail below.

[0165] With the rapid development of technology, users' demands for communication are also increasing. Satellite base stations based on the New Radio (NR) Non-Terrestrial Network (NTN) standard support on-board regeneration mode, enabling user equipment (UE) devices to directly connect to the satellite base station and provide satellite internet services to the UE. On-board regeneration mode supports the satellite base station in fulfilling the functions of both a base station and the core network, enabling on-orbit data forwarding and processing, thereby reducing the number and complexity of ground gateway stations and improving the coverage and performance of the satellite network. Compared to traditional terrestrial communication networks, satellite base stations have advantages such as wide coverage, long transmission distance, and high mobility. Figure 1As shown in the diagram, this embodiment provides a satellite-borne base station network deployment diagram. The service link is the radio link between the terminal and the satellite-borne base station; the feeder link is the radio link between the satellite-borne base station and the gateway; and the intersatellite link (ISL) is the radio link between satellite-borne base stations. The satellite-borne base station provides connectivity between the service link and the feeder link. NTN supports the following three types of service links, and other links also support the following types, as detailed below:

[0166] (1) Earth-fixed: The beam continuously covers the same geographical area. For example, for a geostationary Earth Orbit Satellite (GSO).

[0167] (2) Quasi-Earth-fixed: The beam covers one geographic area in a finite period and another geographic area in another period. For example, the tunable beam generated by a non-Geostationary orbit (NGSO) satellite.

[0168] (3) Earth-moving: The area covered by the beam slides across the Earth's surface. For example, the fixed or non-tunable beam generated by the NGSO satellite.

[0169] A serving cell (Cell) refers to dividing the entire service area (the entire service area provided by one or more base stations) into many small, independent regions (Cells). Each region (Cell) is covered by one base station, forming a honeycomb-like structure. This division helps the communication system allocate resources more flexibly, improve the spectrum efficiency of the communication system, reduce interference, provide more reliable information coverage, and effectively manage network capacity. Optionally, the base stations in this embodiment include terrestrial base stations and / or spaceborne base stations. A beam footprint refers to the projection area of ​​a beam on the ground. The beam is the shape formed on the Earth's surface by the electromagnetic waves emitted by the antenna. A cell (a serving cell) is usually divided into many beam footprints. Beam footprints are generally elliptical. In the case of Quasi-Earth-fixed, the beam footprint is usually an area bound to the ground, and this bound area remains fixed within a certain period. In the case of Earth-moving, the beam footprint usually moves with the cell. Tracking Area Identity (TAI): TAI consists of the Public Land Mobile Network (PLMN) and the Tracking Area Code (TAC). TAI is a technology used by the core network to manage and determine the location of the UE. The NTN network divides the ground into tracking areas, each with a specific identifier (TAI). The base station broadcasts the TAI of the current cell through the System Information Block (SIB) SIB1 message.

[0170] After a UE registers, the core network assigns it a TAI list. If the UE moves out of the current TAI list, it triggers a registration area update procedure, and the core network reassigns a new TAI list. This way, even in the idle (RRC_IDLE) state, the core network can determine the UE's TAI list and page it within that list. For non-terrestrial networks (NTN), due to the high-speed movement of satellites, the serving cell of a terminal frequently switches, and the TAI of the serving cell changes frequently. Furthermore, the coverage area of ​​NTN cells is very large (e.g., hundreds to thousands of kilometers, much larger than the coverage radius of terrestrial network cells). Therefore, NTN introduces a new TAI management mechanism. First, a serving cell may cover multiple tracking areas. Therefore, SIB1 introduces the parameter trackingAreaList-r17, which indicates the TAI list to which the current serving cell belongs. The existing protocol stipulates that a serving cell can correspond to a maximum of 12 TAIs. Secondly, a new radio non-terrestrial network TAI information field (NR NTN TAI information field) has been added to the user location information in the initial UE message of the NG interface (the interface between the radio access network and the core network), which can indicate the TAI list (used by the UE's serving PLMN) to which the current serving cell belongs.

[0171] Currently, a single NTN cell corresponds to a maximum of 12 TAIs, and the TAIs belonging to the cell are broadcast via SIB1. If the total area of ​​the TAI list allocated to the UE by the core network is less than the coverage area of ​​a serving cell, then when the UE moves out of the TAI list but does not leave the current serving cell, the UE cannot detect leaving the TAI list and thus cannot trigger the registration domain update process. Therefore, the coverage area of ​​the TAI list allocated to the UE by the core network must be greater than or equal to the coverage area of ​​the serving cell. Thus, when the core network pages the UE, it needs to page within at least one NTN cell. Here, the NTN cell refers to the serving cell of the satellite base station. On the one hand, because the coverage area of ​​a satellite base station cell is very large, a cell is usually divided into many beams; on the other hand, due to the limitations of the satellite base station's radio frequency capabilities and power consumption, the number of beams that can be activated simultaneously is limited. Therefore, when paging, non-terrestrial networks typically need to poll between multiple beams to send public messages such as broadcasts or paging messages. As a result, the time to paging a UE in an NTN network is much longer than that in a terrestrial network. This leads to low paging efficiency and waste of valuable radio resources, as well as excessively long service setup times, which affects user experience.

[0172] Optionally, the core network in this embodiment includes a terrestrial core network and / or the core network of a satellite-based base station. The base station in this embodiment includes a terrestrial base station and / or a satellite-based base station. Optionally, the serving cell in this embodiment includes a serving cell of a satellite-based base station and / or a serving cell of the terrestrial network. The cell in this embodiment includes a cell of a satellite-based base station and / or a cell of the terrestrial network.

[0173] To address the aforementioned technical issues, this application provides a paging method. By establishing the association between wavelet information and TAI, a wavelet-level TAI list is configured for the UE. Specifically, a first TAI list to which one or more wavelet-level TAIs belong can be configured. Instead of paging the UE throughout the entire NTN cell, the satellite base station / base station paging the UE within the wavelet-level TAI list effectively improves paging efficiency, shortens paging latency, and enhances user experience by paging the UE based on the wavelet information.

[0174] It should be noted that NTN has two typical architectures: pass-through mode and regeneration mode.

[0175] 1) Transparent payload mode: This mode features RF filtering, frequency conversion, and amplification. Therefore, the waveform signal of the payload remains unchanged. In other words, the satellite only forwards the signal without performing any other processing; that is, in transparent payload mode, the base station does not participate in the transmission, and the satellite is only used for transmission, without any base station functionality.

[0176] 2) Regenerative payload mode features RF filtering, frequency conversion and amplification, as well as demodulation / decoding, switching and / or routing, and encoding / modulation functions. This is essentially equivalent to having all or part of the base station functionality (e.g., gNB) on a satellite, which will process the data. In other words, in regenerative mode, the base station is on the satellite, while the core network may or may not be on the satellite.

[0177] Optionally, the network-side equipment in this embodiment includes, but is not limited to, at least one of a base station and a core network; optionally, the base station includes, but is not limited to, at least one of a terrestrial network base station and a satellite-borne base station; optionally, the core network includes, but is not limited to, at least one of a terrestrial network core network and a satellite-borne base station core network.

The specific implementation flow of this method is as follows:

[0180] Step 200: The first network device sends a first message to the UE. The first message includes at least one set of wave position information. The set of wave position information includes at least one wave position information. The set of wave position information is associated with a tracking area identifier (TAI).

[0181] Optionally, the first message in this embodiment includes, but is not limited to, system messages or other messages.

[0182] Optionally, the first network device sends a system message to the UE. The first network device broadcasts the system message to the UE via a broadcast method. The system message includes at least one set of wave position information. One set of wave position information is associated with one TAI. The UE can determine one or more TAIs corresponding to the current wave position based on the association between the TAI and the set of wave position information.

[0183] Optionally, the first network device determines the association between TAIs and wavelength information. Specifically, one (serving) cell corresponds to one TAI list, each TAI in the TAI list is associated with a set of wavelength information, and a set of wavelength information includes one or more wavelength information items.

[0184] It should be noted that in non-terrestrial networks, each cell typically needs to be divided into multiple wavelengths, each corresponding to a specific ground area. The correspondence between wavelengths and ground areas can be planned in advance. When the serving cell changes, the ground area corresponding to a wavelength may also change. Furthermore, the TAI (Terrestrial Area Identity) and the ground area are bound together; the binding relationship between TAI and ground area is fixed, meaning the ground area corresponding to a TAI is fixed.

[0185] In some embodiments, the first network device determines the association between TAI and wavelength information in the following manner:

[0186] The first network device determines the set of wave position information associated with each TAI in the TAI list based on the TAI list corresponding to the serving cell; and determines the wave position information associated with each TAI based on the set of wave position information associated with each TAI.

[0187] In implementation, each serving cell is configured with a TAI list, which includes one or more TAIs. When configuring the association between TAIs and wavelength information, each TAI in the serving cell's TAI list is configured with a wavelength information set, so that each TAI in the TAI list is associated with a wavelength information set, and a wavelength information set includes one or more wavelength information.

[0188] In some embodiments, the first network device sends a first message to the UE in the following manner:

[0189] The first network device configures the at least one set of wave position information in a preset field of the first message and sends the first message to the UE.

[0190] In practice, by configuring at least one set of wave position information in a preset field of the first message, such as a system message, the association between TAI and wave position information is carried in the first message, and the first message is sent to the UE. The UE determines the association between TAI and wave position information based on the TAI parameter and at least one set of wave position information in the first message.

[0191] Optionally, the system messages in this embodiment include, but are not limited to, SIB1 messages, SIB2 messages, ..., SIB19 messages, ..., SIBn messages, where n is an integer greater than or equal to 1. Optionally, the system messages in this embodiment can be SIB1 messages or SIB19 messages, or they can be newly added SIB messages. This embodiment does not impose too many limitations on this.

[0192] In some embodiments, the association between the TAI and the wave position information is sent to the UE via a system message in the following manner:

[0193] Configure the wave position information in a preset field of the system message; send the system message to the UE so that the UE can obtain the association relationship between TAI and wave position information based on the TAI parameter and wave position information in the system message.

[0194] Optionally, a preset field, such as a wave position identifier field, can be added to the PLMN-IdentityInfo field of the SIB1 message. Optionally, the TAI parameters include, but are not limited to, PLMN and TAC. The TAI is determined based on PLMN and TAC. It should be noted that the PLMN-IdentityInfo field of the SIB1 message contains PLMN and TAC, thus determining the TAI parameters based on the SIB1 message. In system messages, the TAI parameters are used to determine the TAI, and the corresponding TAI is determined based on the PLMN and TAC in the system message; one TAI is determined by one PLMN and one TAC.

[0195] Optionally, the parameter ntn-PLMN-IdentityInfoList can be added to the SIB19 message, defined as follows:

[0196]

[0197] The number of NTN-PLMN-IdentityInfo entries is equal to and corresponds one-to-one with the number of PLMN-IdentityInfo entries in SIB1, and the number of BeamFootprint-IDList entries is equal to and corresponds one-to-one with the number of TrackingAreaCode entries in SIB1.

[0198] In some embodiments, after determining the association between TAI and wave position information, the first network device may also carry the association between TAI and wave position information in a first message other than a system message and send it to the UE.

[0199] Optionally, the wave position information in this embodiment includes, but is not limited to, at least one of wave position identifier and wave position name.

[0200] In implementation, beam position information (such as a beam position identifier) ​​is introduced into the system message. This beam position information is associated with each beam position. The beam position information is different for each beam position within the same cell, and the beam position information in different cells can be the same or different (this beam position information is unique within the cell or globally). For example, a beam position identifier BeamFootprint ID parameter can be added to the SIB message, as shown below:

[0201] BeamFootprint-ID::=INTEGER(0..maxNrofBeamFootprints-1)

[0202] maxNrofBeamFootprints INTEGER::=1024--Maximum number of BeamFootprints in a cell.

[0203] For example, the association between TAI and Beam Footprint ID can be defined as follows: define the set of Beam Footprint IDs associated with each TAI of the cell, that is, add a Beam Footprint ID field to the PLMN-IdentityInfo field of the SIB1 message, as shown below:

[0204] PLMN-IdentityInfoList::=SEQUENCE(SIZE(1..maxPLMN))OF PLMN-IdentityInfo

[0205] PLMN-IdentityInfo::=SEQUENCE{

[0206] plmn-IdentityList SEQUENCE(SIZE(1..maxPLMN))OF PLMN-Identity,

[0226] }

[0227] / *The following is an example of defining a new BeamFootprint-IDList set of wave position identifiers* /

[0228] BeamFootprint-IDList::=SEQUENCE(SIZE(1..maxNrofBeamFootprints))OFBeamFootprint-ID.

[0229] Among them, maxNrofBeamFootprints represents the maximum number of beams in a cell.

[0230] In some embodiments, the number of elements in beamFootprint-IDList-rxx is the same as the number of elements in trackingAreaList-r17, and they correspond one-to-one. That is, the first TrackingAreaCode of trackingAreaList-r17 corresponds to the first BeamFootprint-IDList of beamFootprint-IDList-rxx, the second TrackingAreaCode of trackingAreaList-r17 corresponds to the second BeamFootprint-IDList of beamFootprint-IDList-rxx, and so on. Each TAC is associated with a beam position identifier list, and the same beam position can belong to multiple TACs of the same (or the same group) PLMN.

[0231] In some embodiments, the TAI includes a PLMN and a TAC, wherein the TAI is determined based on the PLMN and the TAC, and a TAI is determined by a PLMN and a TAC, and the TAI changes when at least one of the PLMN and the TAC changes.

[0232] Optionally, the association between TAI and the wave position information set in this embodiment includes any one or more of the following:

[0233] Item a1: One TAI is associated with one set of wave position information, wherein one TAI is determined based on one TAC corresponding to one PLMN;

[0234] In practice, TACs belong to PLMNs, meaning one or more TACs belong to one PLMN, or one or more TACs belong to a group of PLMNs (network sharing scenario). Therefore, PLMNs and TACs have a corresponding relationship, and one TAC corresponding to one PLMN is associated with one set of waveform information.

[0235] Item a2: A set of TAIs is associated with a set of wave position information, wherein the set of TAIs is determined based on a set of PLMNs corresponding to a TAC.

[0236] In implementation, a set of PLMNs corresponds to a TAC associated with a set of wave position information. Optionally, different PLMNs in a set of PLMNs in this embodiment may belong to the same PLMN list or different PLMN lists. This embodiment does not impose too many limitations on this.

[0237] In some embodiments, one TAI corresponds to one TAC, and one TAC corresponds to one set of wave position information; this embodiment also includes any of the following associations:

[0238] For item b1, some of the wave position information in the wave position information sets corresponding to multiple TACs overlap;

[0239] In practice, the same wave position information can belong to multiple TACs of the same PLMN, which can also be understood as multiple TACs corresponding to one PLMN being associated with the same wave position information; or, the same wave position information can belong to multiple TACs of the same group of PLMNs, that is, multiple TACs corresponding to one group of PLMNs being associated with the same wave position information.

[0240] It should be noted that the wave position information sets corresponding to different TACs in the same PLMN list cannot be completely identical.

[0241] For item b2, all wave position information in the wave position information sets corresponding to multiple TACs does not overlap.

[0242] In practice, multiple TACs corresponding to one PLMN are associated with different wave position information; or, multiple TACs corresponding to a group of PLMNs are associated with different wave position information.

[0243] like Figures 3A-3B As shown in the figure, this embodiment provides a schematic diagram of the association relationship between cell-TAI-wave position identifier, wherein... Figure 3A PLMN1 and PLMN2 belong to the same group of PLMNs. Figure 3B PLMN3 belongs to a different group of PLMNs than PLMN1 and PLMN2. One cell corresponds to one PLMN or a group of PLMNs, one cell corresponds to one or more TACs, and one TAC corresponds to one or more beam position information (such as beam position identifiers). Within a System Message (SIB), a PLMN-IdentityInfo includes one or more PLMNs, one or more PLMNs correspond to one cell identifier (Cell ID), one Cell ID corresponds to one or more TACs, and one TAC corresponds to one or more beam position identifiers (Beam Footprint IDs). Furthermore, TACs within the same PLMN list are not identical. The information from PLMNs and TACs together constitutes the TAI information. Figure 3A For example, PLMN1 and TAC1 form TAI11, PLMN1 and TAC2 form TAI12, and so on, PLMNi and TACj form TAIij, where i and j are integers greater than or equal to 0.

[0244] In some embodiments, the association between TAI and wave position information in this embodiment includes any one or more of the following:

[0245] 2a) One TAI corresponds to one or more waveform information;

[0246] 2b) At least two different TAIs correspond to the same wave position information;

[0247] 2c) At least two different TAIs correspond to different wave position information.

[0248] like Figure 4 As shown in the diagram, this embodiment also provides an example diagram of the association between TAI and wave positions. Cell A corresponds to TAI1, TAI2, and TAI3, and cell B corresponds to TAI2 and TAI3. In the case of earth-moving, the association between TAI and wave positions changes as the serving cell moves. Based on the association between TAI and wave positions, adding a wave position identifier field to the PLMN-IdentityInfo field of SIB1 can associate wave positions with TAI. By establishing the association between wave position information and TAI, paging efficiency is improved while requiring minimal changes to the protocol, thus better compatibility with existing protocols.

[0249] In some embodiments, the first network device may also update the association relationship and notify the UE in the following manner:

[0250] In response to a change in the association between TAI and wave position information, the first network device updates the set of wave position information associated with TAI; and sends a first message to the UE, the first message including the updated set of wave position information.

[0251] During implementation, the first network device updates the association between the TAI and the wave position information, and sends the updated association between the TAI and the wave position information to the UE via a system message.

[0252] Optionally, when the association between TAI and wavelet information changes, a system message change notification is not triggered. The system message is only read when the UE moves. This allows the UE to update its TAI information promptly, effectively reducing UE power consumption and overall energy efficiency. If the UE does not move, because the TAI and ground area have a fixed binding relationship, the correspondence between the UE and the TAI remains unchanged. Even if the wavelet shifts within the wavelet information set corresponding to the TAI, the UE's corresponding TAI will not change. Therefore, there is no need to trigger a system message change notification in this case, i.e., there is no need to read a new TAI list. The system message is only read when the UE moves, thus reducing UE power consumption while updating the TAI list.

[0253] Step 201: The first network device determines the first TAI list to which the TAI corresponding to the current wave position of the UE belongs based on the association relationship between TAI and wave position information. The first TAI list includes at least one TAI.

[0254] Optionally, when a UE accesses the network, the current waveform position of the UE is determined; and the first TAI list to which the TAI corresponding to the current waveform position belongs is determined based on the association between the TAI and the waveform position information. Optionally, the first TAI list includes one or more TAIs.

[0255] Step 202: The first network device sends the first TAI list to the second network device;

[0256] Step 203: The second network device determines a second TAI list based on the first TAI list and sends it to the first network device, wherein the second TAI list includes the first TAI list;

[0257] Optionally, after determining the second TAI list, the second TAI list is sent to the UE through the first network device, or the second TAI list is sent directly to the UE, so as to determine whether the UE has left the second TAI list after moving, thereby triggering the registration domain update.

[0258] Optionally, the second network device (core network) allocates a second TAI list to the UE, which includes the first TAI list, based on the first TAI list. Optionally, the second TAI list contains at least the first TAI list.

[0259] Optionally, the first network device (base station) determines a second TAI list based on the first TAI list, wherein the second TAI list includes the first TAI list.

[0260] In some embodiments, the first network device determines the first TAI list in the following manner:

[0261] When a UE accesses the network, the current wave position of the UE is determined, and the first TAI list to which the TAI corresponding to the current wave position belongs is determined based on the association between the TAI and the wave position information.

[0262] In some embodiments, the second network device determines the second TAI list in the following manner:

[0263] When a paging UE is identified, the second network device determines a second TAI list that at least includes the first TAI list, based on the first TAI list.

[0264] In practice, when a UE accesses the network, it initiates a Random Access (RA) procedure at a specific frequency band. After identifying the UE's current frequency band, the network-side device determines the first TAI list based on the configured relationship between the TAI and frequency band information. It then determines a second TAI list, which at least includes the first TAI list, and assigns the second TAI list to the UE. Subsequently, when the UE enters idle mode, if paging is required, the network sends a paging message to the corresponding frequency band information set for each TAI in the second TAI list.

[0265] In some embodiments, after determining the second TAI list, the second network device may also send the second TAI list to the UE through the first network device (e.g., a base station). Alternatively, the second network device may send the second TAI list to the UE through the first network device. In practice, the second network device (e.g., a core network) allocates the second TAI list to the UE for the UE to determine whether an update of the registration domain is required.

[0266] Step 204: The first network device sends a paging message to the UE based on the set of wave position information corresponding to the TAI in the second TAI list.

[0267] In practice, after the second network device initiates a paging, the first network device sends a paging message to the UE on each wave position associated with the TAI in the second TAI list.

[0268] Optionally, different paging parameters can be configured for different wave position information. Optionally, paging parameters include, but are not limited to, paging timing. For example, configuring the paging timing to associate with the wave position identifier, and configuring different paging timings for different wave positions, can achieve the purpose of saving UE power.

[0269] In some embodiments, the first network device sends a paging message to the UE based on the set of wave position information corresponding to the TAI in the second TAI list in the following manner:

[0270] Based on the paging parameters of each wave position information in the wave position information set corresponding to the TAI in the second TAI list, a paging message is sent to the UE.

[0271] As an optional implementation, different paging parameters can be configured for different wave position information.

[0272] In practice, different paging parameters are configured for different wave positions. When a second network device, such as the core network, needs to page a UE, the base station sends a paging message for the UE on the wave position information set corresponding to each TAI in the UE's second TAI list.

[0273] Optionally, different wave position information can also be configured with the same paging parameters.

[0274] The paging method provided in this embodiment defines beam position (i.e., the projection area of ​​the beam on the ground) information, associates TAI with beam position information, and notifies the association relationship between the beam position information and TAI in the broadcast. Therefore, the range of the second TAI list configured by the core network for the UE can be less than one cell, meaning one or more beam position sizes can be configured for the UE's second TAI list. When the UE moves to a new beam position, the UE reads the broadcast to learn about the second TAI list associated with the current beam position. If it determines that the TAI of the current beam position is not within the range of the second TAI list, the registration domain update process is triggered.

[0275] In some embodiments, the first network device (such as a base station) of this embodiment may also perform the following steps:

[0276] Receive capability information sent by the UE; when the capability information indicates that the UE supports paging based on wavenumber, send a first message to the UE.

[0277] In implementation, a UE capability field is added. The UE sends capability information to the network-side device to indicate whether the UE supports wavebit-based paging. When the first network device receives the capability information and determines that the UE supports wavebit-based paging, it determines the association between the TAI and the wavebit information and sends the association to the UE in the first message.

[0278] Optionally, the following UE-level capability fields can be added to the UE Capability Information:

[0279] BeamFootprintPaging ENUMERATED{supported}OPTIONAL.

[0280] When a UE reports this field, it indicates that the UE supports paging by wavelength. Based on this UE capability field, the core network determines whether the size of the TAI list allocated to the UE is cell-level (i.e., the TAI list range must be greater than or equal to the cell level) or wavelength-level (i.e., the TAI list range can be smaller than the cell level). Only when the UE supports wavelength-based paging will the core network allocate a wavelength-level TAI list. In this case, the network-side equipment determines the association between TAIs and wavelength information, and based on this association, determines the first TAI list to which the TAI corresponding to the UE's current wavelength belongs, as well as the set of wavelength information corresponding to the TAIs in that TAI list; and sends a paging message to the UE based on the set of wavelength information corresponding to the TAIs.

[0281] like Figure 5 As shown in the figure, this embodiment provides a paging method based on wave position. Taking wave position information including wave position identifier as an example, the implementation process of this method is as follows:

[0282] Step 500: The base station determines the association between the TAI and the wave position identifier, and broadcasts the association between the TAI and the wave position identifier through SIB messages;

[0283] Optionally, when the association changes, the corresponding SIB message is updated.

[0284] Optionally, the base station may include, but is not limited to, at least one of terrestrial base stations and spaceborne base stations.

[0285] Optionally, the network management, operations and maintenance, or other functional entities configure the binding relationship between TAI and ground area, and assign this binding relationship to the base station and / or core network. The base station determines the association between the TAI and the wavelet identifier based on the binding relationship between the TAI and the ground area, and the wavelet's ground area planning. The wavelet's ground area planning includes, but is not limited to, pre-planning the correspondence between wavelets and ground areas, and the changes in the wavelet's ground area. When the UE's serving cell changes, the ground area corresponding to the wavelet will also change.

[0286] Step 501: The UE initiates the RA (Random Access) procedure on a waveform position;

[0287] Step 502: The base station determines the current wave position of the UE, determines the first TAI list to which the TAI corresponding to the current wave position belongs according to the association relationship, and sends an initial UE message to the core network, wherein the initial UE message carries the first TAI list;

[0288] During implementation, the base station determines the current waveform of the UE and determines the first TAI list corresponding to the UE based on the current waveform of the UE. In the initial UE message sent to the core network, the TAI list field is filled in according to the TAI.

[0289] It should be noted that the base station can obtain information for each wavelength. When the base station receives Msg1 (i.e., random access message preamble) sent by the UE at a certain wavelength, it has already determined the current wavelength of the UE.

[0290] Step 503: In the registration response message, the core network assigns a second TAI list to the UE based on the first TAI list currently corresponding to the UE carried in the initial UE message;

[0291] The second TAI list contains at least the first TAI list.

[0292] In practice, the core network forwards the allocated second TAI list to the UE through the base station.

[0293] Step 504: The UE saves the second TAI list assigned by the core network;

[0294] Optionally, when the UE enters the idle state and moves, if the UE determines, based on the current wave position identifier, that the third TAI list to which the TAI corresponding to the current UE wave position belongs is no longer in the current second TAI list, then the registration domain update process is triggered to obtain a new second TAI list.

[0295] Step 505: When the core network needs to page the UE, it sends a paging message to the base station corresponding to the second TAI list according to the UE's second TAI list.

[0296] Step 506: The base station queries the association between TAI and wave position identifier according to the second TAI list, and sends the paging message of the UE to the wave position corresponding to the TAI in the second TAI list.

[0297] This embodiment associates TAI with waveform information, allowing the core network to configure a smaller range of TAI lists for the UE. When the core network pages the UE, the base station can perform paging according to the waveform, effectively improving paging efficiency, reducing paging latency, and enhancing user experience.

[0298] like Figures 6A-6CAs shown, this embodiment also provides a schematic diagram of the correspondence between TAI and cell wavelengths at different time points. In an earth-moving scenario, the correspondence between TAI and wavelengths changes as the cell moves. The hexagonal areas represent three adjacent TAI1, TAI2, and TAI3, all bound to a ground area, and this binding relationship remains fixed. Cell A in the diagram has 0-15 wavelengths, and cell B also has 0-15 wavelengths. As cells A and B move, the correspondence between TAI and cell wavelengths changes. See also... Figure 6A At time point T1: TAI1 corresponds to wave positions 0, 3, 4, 7, 8, and 11 in cell A; TAI2 corresponds to wave positions 1, 2, 4, and 5 in cell A; and TAI3 corresponds to wave positions 8, 9, 12, 13, 14, and 15 in cell A. See also... Figure 6B At time point T2: TAI1 corresponds to wave positions 3 and 7 in cell A and wave positions 6, 10, and 13 in cell B; TAI2 corresponds to wave positions 0, 1, 3, and 4 in cell A; TAI3 corresponds to wave positions 7, 8, 11, 12, and 14 in cell A. See also... Figure 6C At time point T3: TAI1 corresponds to wave positions 2, 5, 6, 9, 10, and 13 in cell B; TAI2 corresponds to wave positions 0, 3, and 4 in cell A; and TAI3 corresponds to wave positions 7, 8, 11, and 14 in cell A.

[0299] like Figure 7 As shown in the figure, this embodiment also provides a UE registration flowchart, which is shown below:

[0300] Step 701: The base station determines the association between TAI and wavelet information, and broadcasts the association between TAI and wavelet information through SIB messages;

[0301] In practice, the association between TAI and wave position information is carried in the SIB message by adding at least one set of wave position information.

[0302] Step 702: The UE initiates a random access procedure at a specific wavelength.

[0303] Step 703: The base station queries the association between TAI and wave position information based on the wave position where the UE is currently located, and obtains the first TAI list where the UE is located;

[0304] The first TAI list includes one or more TAIs.

[0305] Step 704: The base station sends the first TAI list to the core network and initiates a registration request;

[0306] The base station adds the first TAI list information to the initial UE message.

[0307] Step 705: Identity recognition, authentication, and security procedures are performed between the core network and the UE.

[0308] Step 706: The core network sends a registration response message and assigns a second TAI list to the UE;

[0309] Step 707: The UE replies with a registration completed message.

[0310] After UE registration is complete, when the UE enters the idle state and the network needs to send data to the UE, a paging process is triggered, such as... Figure 8 As shown in the figure, this embodiment provides a paging process based on wave position, and the specific implementation process is as follows:

[0311] Step 801: The core network sends a paging message to the base station, and the paging message carries the second TAI list;

[0312] The core network allocates a second TAI list to the UE.

[0313] Step 802: The base station queries the correlation between TAI and wavelet information to obtain the set of wavelet information corresponding to each TAI in the second TAI list;

[0314] Step 803: The base station sends a paging message on the set of wave position information corresponding to each TAI.

[0315] This embodiment proposes a novel paging mechanism that associates TAI (Target Information Identifier) ​​with wavelet information, allowing the TAI list to be configured with one or more wavelet sizes. When the UE moves, it can identify changes in wavelet size by receiving system messages, thereby recognizing changes in TAI. When the UE moves out of the current TAI list, a registration domain update process is triggered. The base station performs fast paging based on wavelet size. Compared with existing technologies, this application effectively improves paging efficiency, reduces paging latency, and enhances user experience. This application also adds a field indicating whether the UE supports wavelet-based paging capabilities. This application is applicable to fixed, quasi-fixed, and earth-moving scenarios. The paging method provided in this application is also applicable to terrestrial networks.

[0316] Based on the same inventive concept, such as Figure 9 As shown in the figure, this application embodiment also provides a paging method, applied to a network-side device, and the specific implementation flow of the method is as follows:

[0317] Step 900: Send a first message to the UE. The first message includes at least one set of wave position information. The set of wave position information includes at least one wave position information. The set of wave position information is associated with a tracking area identifier (TAI).

[0318] Step 901: Based on the association between TAI and wave position information, determine the first TAI list to which the TAI corresponding to the current wave position of the UE belongs. The first TAI list includes at least one TAI.

[0319] As an optional implementation method, the correlation between TAI and wave position information is determined in the following way:

[0320] Based on the TAI list corresponding to the serving cell, determine the set of wave position information associated with each TAI in the TAI list;

[0321] Based on the set of wave position information associated with each TAI, determine the wave position information associated with each TAI.

[0322] As an optional implementation, sending the first message to the UE includes:

[0323] The at least one set of wave position information is configured in a preset field of the first message, and the first message is sent to the UE.

[0324] As an optional implementation, the TAI includes a Public Land Mobile Network (PLMN) and a Tracking Area Code (TAC); the association between the TAI and the waveform information set includes any one or more of the following:

[0325] A TAI is associated with a set of wave position information, wherein a TAI is determined based on a TAC corresponding to a PLMN; or,

[0326] A set of TAIs is associated with a set of wave position information, and the set of TAIs is determined based on a set of PLMNs corresponding to a TAC.

[0327] As an optional implementation, one TAI corresponds to one TAC, and one TAC corresponds to one set of waveform information; it also includes:

[0328] Some wave position information in the wave position information sets corresponding to multiple TACs overlaps; or,

[0329] All wave position information in the wave position information sets corresponding to multiple TACs does not overlap.

[0330] As an optional implementation, the method further includes:

[0331] Send the first TAI list to the second network device;

[0332] Receive a second TAI list sent by the second network device, wherein the second TAI list includes the first TAI list;

[0333] A paging message is sent to the UE based on the set of wave position information corresponding to the TAI in the second TAI list.

[0334] As an optional implementation, the method further includes:

[0335] Send the second TAI list to the UE.

[0351] Based on the same inventive concept, such as Figure 10As shown in the figure, this application embodiment also provides a paging method, applied to a network-side device, and the specific implementation flow of the method is as follows:

[0352] Step 1000: Receive the first TAI list sent by the first network device;

[0353] Step 1001: Determine a second TAI list based on the first TAI list, wherein the second TAI list includes the first TAI list;

[0354] Step 1002: Send a paging message to the first network device, wherein the paging message carries a second TAI list.

[0355] As an optional implementation, determining the second TAI list based on the first TAI list includes:

[0356] When a paging UE is identified, a second TAI list that at least includes the first TAI list is determined based on the first TAI list.

[0357] As an optional implementation, the second network device determines the association between the TAI and the waveform information set. Optionally, the second network device determines the association between the TAI and the waveform information.

[0358] As an optional implementation, different paging parameters can be configured for different wave position information.

[0359] As an optional implementation, the method further includes:

[0360] The second TAI list is sent to the UE; or, the second TAI list is sent to the first network device, so that the first network device can send the second TAI list to the UE.

[0361] Based on the same inventive concept, such as Figure 11 As shown in the figure, this application embodiment also provides a paging method applied to a terminal, and the specific implementation flow of the method is as follows:

[0362] Step 1100: Receive a first message, the first message including at least one set of wave position information, the set of wave position information including at least one wave position information, wherein the set of wave position information is associated with TAI;

[0363] During implementation, the first message sent by the first network device is received.

[0364] Step 1101: Initiate a random access procedure to the network-side device.

[0365] Optionally, a random access procedure may be initiated to a first network device. The first network device may include a base station, such as a terrestrial base station and / or a satellite-based base station.

[0366] This application provides a paging method that sends the association between wavelet information and TAI to the UE by sending a first message, and configures a wavelet-level TAI list for the UE, so as to facilitate paging of the UE by the network-side device.

[0367] As an optional implementation, the first message further includes a TAI parameter; the method further includes:

[0368] The association between TAI and wave position information is determined based on the TAI parameters and the wave position information in the at least one wave position information set.

[0372] Based on the second TAI list and the third TAI list, determine whether to trigger a registration domain update.

[0373] During implementation, the terminal triggers a registration domain update, and the network-side device allocates a new second TAI list to the terminal. The UE obtains the new second TAI list. When it is necessary to page the UE, a paging message is sent to the UE according to the set of wave position information corresponding to the TAI in the new second TAI list.

[0374] In practice, the network-side equipment allocates a second TAI list to the UE. Whether a registration domain update is triggered depends on whether the third TAI list is included in the second TAI list. If the third TAI list is not included in the second TAI list, a registration domain update is triggered, meaning the UE needs to obtain a new second TAI list; if the third TAI list is included in the second TAI list, a registration domain update is not triggered.

[0375] Since the TAI list configured for the UE is at the wave position level, when the UE moves to a new wave position, the UE checks the TAI list to which the TAI corresponding to the current wave position belongs. If it determines that the TAI of the current wave position is not within the range of the TAI list configured for the current UE, the registration domain update process is triggered.

[0376] As an optional implementation, the TAI includes PLMN and TAC; the association between the TAI and the wave position information set includes any one or more of the following:
