Description

Technical Field

[0001] This application relates to the field of communication technologies, and more specifically, to a method for communication, a positioning server, an access network device, and a terminal device.

Background Art

[0002] In order to reduce power consumption, communication devices can avoid (i.e., not perform) some communication actions. For example, considering that access needs to consume more power, for a positioning service, the terminal device may not need to perform access in a new cell, or the terminal device may not need to perform radio resource management (RRM) measurements related to access.

[0003] In some scenarios, the communication device does not perform a certain action or some actions to reduce power consumption, but instead causes an increase in the power consumption of the terminal device. Hereinafter, the case where the terminal device does not perform RRM measurements will be taken as an example for explanation. Since the terminal device does not perform RRM measurements, it is difficult to determine information about the cell corresponding to the current location (for example, the serving cell and / or adjacent cells). On the one hand, in the process of the terminal device performing pilot transmission or reception, there may be invalid pilot transmission or reception. For example, the terminal device may perform invalid sounding reference signal (SRS) transmission or detection of downlink positioning signals. On the other hand, when the terminal device transmits SRS using transmit beam scanning or receives positioning reference signal (PRS) using receive beam scanning, it may perform invalid transmission or reception, thereby wasting resources. For example, when the terminal device transmits SRS according to the beam scanning method, if there is no base station in a certain direction, the SRS transmission in these directions is invalid, thereby causing resource waste and consuming the power of the terminal device.

Mode for Carrying Out the Invention

[0020] Hereinafter, the technical solution in the present application will be described while referring to the drawings. Communication system

The communication devices may include a network device 110 and a terminal device 120. The network device 110 may be a device that communicates with the terminal device 120. The network device 110 can provide communication coverage in a specific geographical area and communicate with the terminal device 120 located within the coverage area.

[0025] In the embodiments of this application, terminal equipment may also be called user equipment (UE), access terminal, user unit, user station, mobile station (MS), mobile terminal (MT), remote station, remote terminal, mobile device, terminal equipment, terminal, wireless communication device, user agent, or user device. In the embodiments of this application, terminal equipment may refer to equipment that provides voice and / or data connectivity to a user, and can be used to connect humans, objects, and machines, such as handheld devices and in-vehicle devices with wireless connectivity. The terminal devices in the embodiments of this application may include mobile phones, tablet PCs (Pads), notebook computers, palmtop computers, mobile internet devices (MIDs), wearable devices, virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control, wireless terminals in self-driving, wireless terminals in remote medical surgery, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, and wireless terminals in smart homes. Optionally, the UE can function as a base station. For example, the UE can function as a scheduling entity and provide sidelink signals between UEs in vehicle-to-everything (V2X) or device-to-device (D2D) communication. For example, a cellular phone and a car communicate with each other using sidelink signals. It eliminates the need for base stations to relay communication signals, allowing communication directly between cellular phones and smart home devices.

[0026] The network equipment in the embodiments of this application may be equipment for communicating with terminal equipment. The network equipment may also include access network equipment. Access network equipment may be called wireless access network equipment or base stations, etc. The access network equipment in the embodiments of this application may be a radio access network (RAN) node (or equipment) that provides terminal equipment to a wireless network. Access network equipment broadly covers various names such as NodeB, evolved NodeB (eNB), next-generation NodeB (gNB), relay station, access point, transmitting and receiving point (TRP), transmitting point (TP), master eNB (MeNB), secondary eNB (SeNB), multi-standard radio (MSR) node, home base station, network controller, access node, radio node, access point (AP), transmission node, transceiver node, baseband unit (BBU), remote radio unit (RRU), active antenna unit (AAU), remote radio head (RRH), central unit (CU), distributed unit (DU), and positioning node, or may be replaced by these names. A base station may be a macro base station, a micro base station, a relay node, a donor node, or something similar, or a combination thereof. A base station may further refer to a communication module, modem, or chip installed within the aforementioned equipment or device.A base station may also be a mobile switching center and equipment that performs base station functions in D2D, V2X, and machine-to-machine (M2M) communications, network-side equipment in a 6G network, or equipment that performs base station functions in future communication systems. A base station can support networks with the same or different access technologies. The embodiments of this application do not limit the specific technologies and specific equipment forms employed in the access network equipment.

[0027] Base stations may be fixed or mobile. For example, a helicopter or drone may be configured as a mobile base station, and one or more cells may move depending on the location of this mobile base station. In another example, a helicopter or drone may be configured as equipment for communicating with another base station.

[0028] In some applications, the network equipment in the embodiments of the present application refers to a CU or DU, or the network equipment may include both a CU and a DU. The gNB may further include an AAU.

[0029] Network equipment and user equipment may be configured on land, whether indoors or outdoors, handheld or vehicle-mounted, on water, or even in the air on an airplane, balloon, or satellite. The embodiments of this application do not limit the scenarios in which the network equipment and user equipment are located.

[0030] Communication equipment related to a wireless communication system may include not only access network equipment and terminal equipment, but also core network equipment. Core network equipment can function as network equipment.

[0031] The core network equipment in the embodiments of this application may include equipment that processes and forwards user signaling and data. For example, the core network equipment may include core network access and mobility management function (AMF), session management function (SMF), user plane gateway, location management function (LMF), etc. The user plane gateway may be a server that has functions such as mobility management, routing, and forwarding for user plane data, and is generally located on the network side, for example, a serving gateway (SGW), packet data network gateway (PGW), or user plane function (UPF). The AMF and SMF may correspond to the mobility management entity (MME) in an LTE system. The AMF is mainly responsible for access, and the SMF is mainly responsible for session management. Naturally, the core network may include other network elements, which will not be listed here.

[0032] It should be understood that all or some of the functions of the communication equipment in this application may be implemented by software functions running on hardware, or by virtualization functions instantiated on a platform (e.g., a cloud platform). Positioning technology

[0033] In communication systems, location-based services (e.g., navigation positioning) are attracting attention. Wireless positioning systems can estimate the location of mobile devices by mapping signal features to spatial locations. Positioning methods can be based on one or more of the following: distance measurement, angle, proximity, and fingerprinting. Each of these is described below.

[0034] For positioning based on distance measurement, a geometric figure (e.g., a circle or hyperbola) can be constructed based on the distance from the terminal device to at least three network devices. Furthermore, the positioning result can be obtained by calculating the intersection points between these geometric figures. Time of arrival (TOA) and time difference of arrival (TDOA) are signal features commonly used in positioning methods based on distance measurement. For positioning methods based on received signal strength (RSS), it is necessary to fit a path loss model.

[0035] For positioning based on angle, the position of a terminal device can be estimated by calculating the angle of arrival (AOA) of at least two input signals.

[0036] For positioning based on proximity, the terminal device's location can be determined by the area covered by the network device with the strongest RSS signal received by the terminal device. Since the area covered by network devices is generally large, this method is simple but has low positioning accuracy.

[0037] For fingerprint-based positioning, an area can be divided into multiple reference points, and by utilizing environmental features, the location of the reference point with the most similar features can be used as the estimated location of the terminal device. Examples of usable signal features include RSS. Fingerprint-based positioning requires collecting positioning data from each reference point to form a fingerprint. Therefore, the accuracy of the fingerprint largely depends on the sufficiency of the dataset. Furthermore, fingerprint-based positioning has lower hardware requirements compared to distance-based positioning methods. From this, it can be seen that fingerprint-based positioning can offer highly accurate positioning results at the expense of training data collection time.

[0038] Positioning technology can be implemented by a positioning server; that is, communication equipment in a communication system may include a positioning server. The positioning server can implement positioning-related functions such as positioning and positioning management of terminal devices. In some embodiments, the positioning server may be called a positioning management device. The positioning server according to the embodiments of this application may include a local location management function (LLMF) located in an LMF network element or network device, and the embodiments of this application are not limited thereto. Low power consumption terminal devices

[0039] With technological advancements, reducing the power consumption of terminal devices has become a crucial research topic. For example, in industries such as logistics, manufacturing, transportation, and energy, terminal devices generally need to have features such as relatively low cost, relatively small size (e.g., ultra-thin), maintenance-free operation, and long lifespan. Low-power communication technologies have been proposed to meet these needs. Low-power communication systems can be used in scenarios such as wireless industrial guidance networks, smart agriculture, smart warehousing and logistics, and smart homes.

[0040] Low-power terminal devices can satisfy one or more of the following characteristics: no battery, small battery capacity, low power consumption, low cost, extreme application environment, and small size. In some embodiments, low-power terminal devices may also be called zero-power communication devices.

[0041] To reduce power consumption, terminal equipment and / or network equipment may avoid (i.e., not perform) certain communication activities. Taking terminal equipment access as an example, considering that access requires significant power consumption when a terminal device moves between cells, the terminal device may not need to access a new cell for positioning services. Similarly, considering the power consumption involved in performing RRM measurements, the terminal device may not need to perform RRM measurements. If access and / or RRM measurements are not performed, the terminal device can perform positioning-related operations based on the previous configuration. For example, the terminal device can transmit uplink positioning SRS and detection downlink positioning signals (e.g., downlink PRS) based on the previous configuration.

[0042] In some scenarios, communication equipment may fail to perform certain actions to reduce power consumption, instead causing an increase in terminal equipment power consumption. The following example illustrates this by considering the case where terminal equipment does not perform RRM measurements. Because terminal equipment does not perform RRM measurements, it is difficult to determine information about the cell corresponding to its current location (e.g., the serving cell and / or adjacent cells). On the one hand, in the process of pilot transmission or reception, terminal equipment may perform invalid pilot transmissions or receptions. For example, terminal equipment may perform invalid SRS transmissions or detect downlink positioning signals. On the other hand, when terminal equipment transmits SRS using transmit beam scanning or receives PRS using receive beam scanning, it may perform invalid transmissions or receptions, thereby wasting resources. For example, when terminal equipment transmits SRS according to a beam scanning scheme, if there is no base station in a certain direction, SRS transmissions in those directions are invalid, resulting in wasted resources and power consumption of the terminal equipment.

[0043] In response to the above situation, the present invention avoids the problem of increased power consumption by using a positioning server to instruct the actions of terminal equipment and / or network equipment (for example, the first action described below). The method according to an embodiment of the present invention will be described below with reference to Figure 2.

[0044] Figure 2 is a schematic flowchart of a communication method according to an embodiment of the present application. The method shown in Figure 2 may be performed by a positioning server. The method shown in Figure 2 may be performed by terminal equipment and / or network equipment. Network equipment may include core network equipment and / or access network equipment. Access network equipment may include, for example, one or more access network equipment corresponding to one or more serving cells of the terminal equipment, access network equipment corresponding to cells that the terminal equipment needs to access, and access network equipment corresponding to one or more adjacent cells of the terminal equipment. Core network equipment may include, for example, AMF network elements. Figure 2 illustrates the case where network equipment is access network equipment. Note that in some embodiments, in the present application, some or all of the operations performed by the positioning server may be performed by core network elements.

[0045] The method shown in Figure 2 may include step S210. In step S210, the positioning server transmits the first information.

[0046] The first information may be used to instruct a first action. The first action may be an action affected by the movement of the terminal's position. The execution of the first action may affect the power consumption of the terminal device. For example, the movement of the terminal's position may change the parameters of the terminal device. The positioning server may obtain the parameter changes of the terminal device based on the estimation of the terminal device's position or the estimated measurement. The first action may be an action performed by the network device and / or the terminal device in response to the positioning server notifying it of the parameter changes. In other words, the positioning server can determine the parameter changes of the terminal device based on the terminal device's position estimation or the position estimation measurement, and the first action may be determined based on the parameter changes of the terminal device. The position estimation may be the position of the terminal device estimated by the positioning server (e.g., coordinates, distance, angle, etc.), and the position estimation measurement may be a measurement for estimating the position (e.g., a measurement of a signal for positioning).

[0047] In some embodiments, the first operation may relate to one or more of RRM measurement, terminal equipment access, transmit beam, receive beam, and TA adjustment. For example, the first operation may be one or more of operations such as RRM measurement, terminal equipment access, and TA adjustment. Alternatively, the first operation may be an operation related to one or more of operations such as RRM measurement, terminal equipment access, and TA adjustment.

[0048] The first information can indicate whether or not to perform the first action, and one or more of the parameter information related to the first action.

[0049] Step S210 may include steps S211 and / or S212. In step S211, the network device receives the first information. In step S212, the terminal device receives the first information. That is, the recipient of the first information may be the network device and / or the terminal device.

[0050] The first action may be an action performed by a terminal device or an action performed by a network device. Thus, the side performing the first action and the side receiving the first information may be the same or different.

[0051] If the executor of the first action and the receiver of the first information are the same, the positioning server can guide or instruct the executor's action based on the first information, thereby reducing the power consumption of the terminal device. For example, if the first action is an action performed by a terminal device, and the receiver of the first information is the terminal device, the positioning server can instruct or guide the terminal device's first action based on the first information, thereby causing the terminal device to perform the corresponding action according to the instructions of the positioning server.

[0052] If the party performing the first action and the party receiving the first information are different, the positioning server can use the first information to notify the party receiving the possible actions the action performer may take, thereby allowing the party receiving the information to adjust the communication process based on the action performed by the action performer and avoid communication errors. If the first action is performed by a terminal device, and the party receiving the first information is a network device, the positioning server can use the first information to notify the network device of the actions the terminal device can take, thereby allowing the network device to adaptively adjust its actions toward the terminal device.

[0053] This application does not limit the method for determining the first information. For example, the first information may be determined based on one or more pieces of information from the cell information of the cell to which the terminal device belongs, and the terminal device information. Each of these will be explained below.

[0054] First, let's explain the cell information of the cell to which the terminal device belongs.

[0055] The cell to which a terminal device belongs may include the cell that covers the terminal device. That is, any cell that can cover the location where the terminal device is located may be called the cell to which the terminal device belongs. Alternatively, any cell accessible to the terminal device may be the cell to which the terminal device belongs. The cell to which a terminal device belongs may include, for example, the serving cell and / or adjacent cells of the terminal device.

[0056] In one embodiment, the cell information may include a cell identifier to distinguish information from different cells.

[0057] In one embodiment, the cell information may include measurement information of the cell's first signal. Based on the measurement information, the positioning server can determine the movement status of the terminal device. The movement status of the terminal device may include one or more of the following: the terminal device's first position, the terminal device's second position, the terminal device's movement speed, etc. The first position may be the terminal device's position in its original cell. Alternatively, the first position may be the position of the terminal device at a first time (e.g., historical time). The original cell may be the terminal device's original resident cell or original access cell. The second position may be the position reached by the terminal device after moving for a certain period of time from the first position. Alternatively, the second position may be the position of the terminal device at a second time (e.g., current time). Based on the movement status of the terminal device, the positioning server can determine whether the terminal device is leaving the coverage area of ​​its original cell, and thereby determine whether the terminal device needs to perform operations such as RRM measurement, cell reselection, or access.

[0058] The first signal may be a signal received and / or transmitted by a terminal device within the cell to which it belongs. For example, the first signal may include one or more signals from among synchronization signals and broadcast blocks (SSB), channel state information reference signals (CSI-RS), cell-specific reference signals (CRS), SRS, PRS, etc.

[0059] The measurement information can indicate the measurement results of the first signal. For example, the measurement information may include one or more of the following measurement results: reference signal received power (RSRP), reference signal received quality (RSRQ), received signal strength indicator (RSSI), and signal-to-interference plus noise ratio (SINR).

[0060] For ease of understanding, we will explain using the example that the cell to which it belongs includes a serving cell. In this case, the cell information may include the serving cell ID and the measured value of the serving cell. The measured value of the serving cell may include one or more of the following information: SSB index (index), SSB RSRP, SSB RSRQ, SSB RSSI, SSB SINR, CSI-RS RSRP, CSI-RS RSSI, CSI-RS RSRQ, CSI-RS SINR, CRS RSRP, CRS RSSI, CRS RSRQ, and CRS SINR.

[0061] For example, if a cell includes adjacent cells, the cell information may include the adjacent cell ID and the measurement values ​​of the adjacent cells. The measurement values ​​of adjacent cells may include one or more of the following: SSB index, SSB RSRP, SSB RSRQ, SSB RSSI, SSB SINR, CSI-RS RSRP, CSI-RS RSSI, CSI-RS RSRQ, CSI-RS SINR, CRS RSRP, CRS RSSI, CRS RSRQ, and CRS SINR.

[0062] The above describes information related to cell information; the following describes information related to terminal devices. Terminal device information may include information related to the terminal device. Based on the terminal device information, the positioning server can provide corresponding first information that matches the status or needs of the terminal device, thereby achieving energy savings.

[0063] As one implementation, terminal device information may include power consumption information of the terminal device. Based on the power consumption information, the positioning server can determine the first information (i.e., how to instruct the first action). For example, if the first action relates to RRM measurement, the terminal device will consume relatively high power when receiving and / or transmitting using a beam that does not match the surrounding environment. In this case, the positioning server can instruct the terminal device to perform an RRM measurement based on whether or not the terminal device is consuming high power. For example, if the power consumption of the terminal device is above a power consumption threshold, the positioning server can instruct the terminal device to perform an RRM measurement based on the first information. If the power consumption of the terminal device is below the power consumption threshold, the positioning server can instruct the terminal device not to perform an RRM measurement based on the first information.

[0064] In one embodiment, the terminal device information may include terminal device positioning information. The terminal device positioning information may include information related to the positioning of the terminal device. For example, the terminal device positioning information may include one or more of the following: positioning results obtained by the positioning process (e.g., terminal device location information), intermediate information in the positioning process (e.g., measured values ​​of positioning signals transmitted or received by the terminal device, fingerprint information), other information obtained based on the positioning results (e.g., terminal device speed, angle, deviation, etc.), and the movement status of the terminal device (see above for an explanation of the movement status).

[0065] Compared to access network devices, positioning servers can combine more information and obtain more accurate positioning information. For example, for cells to which terminal devices belong, access network devices corresponding to these cells have difficulty obtaining information such as positioning detection accuracy and mobility. Therefore, positioning servers can obtain more accurate and complete positioning information for terminal devices, thereby enabling more precise determination of primary information.

[0066] In some embodiments, the positioning information of the terminal device may include fingerprint information for positioning the terminal device, movement information of the terminal device, and positioning deviation information of the terminal device.

[0067] Fingerprint information for positioning the terminal device is obtained by the fingerprint positioning method described above. Based on the fingerprint information, the positioning server can determine whether the terminal device has moved away from its original cell or whether the RRM measurement result has changed, and thereby determine instructions related to the RRM measurement.

[0068] The movement information of the terminal device may be used to indicate the movement status of the terminal device (the description of the movement status is as described above). For example, the positioning server can determine the deviation of the terminal device's position after movement relative to its original cell based on the movement information. The positioning server can determine whether or not the terminal device has moved to a cell other than its original cell. This allows the positioning server to determine information related to the first action. For example, the positioning server can determine instructions related to the measurement of RRM.

[0069] The terminal's location reported from its cell may be the reported location. The terminal's location determined by the positioning server may be the determined location. As can be seen from the above, the positioning server can determine the location of a terminal device based on information reported from multiple cells, and therefore the location of the terminal device determined by the positioning server (i.e., the determined location) is more accurate. Positioning deviation information may be used to indicate the deviation between the reported location and the determined location. Based on the above deviation, the positioning server can determine whether the terminal device requires access or RRM measurement. For example, if RRM measurement includes measurements related to cell reselection, the positioning server can determine whether the terminal device performs measurements related to reselection.

[0070] The above terminal device information and / or cell information may be transmitted from the access network device and / or terminal device to the positioning server, or it may be calculated and obtained by the positioning server.

[0071] The following details the instructions given in the first piece of information.

[0072] If the first action is related to RRM measurement, the first information may be used to indicate one or more of the following: the measurement cycle of the RRM measurement, whether or not the terminal device needs to perform the RRM measurement, whether or not the terminal device needs to report the RRM measurement results, and a first measurement threshold that triggers the terminal device to perform the first action.

[0073] Terminal devices need to evaluate the effectiveness of the SRS before transmitting it. Therefore, the RRM measurement cycle affects SRS effectiveness verification. In related technologies, SRS effectiveness verification is achieved based on the RRM measurement process before paging detection (or paging reception) or discontinuous reception (DRX). However, if the DRX cycle or paging detection cycle is long, the RRM measurement cycle also increases accordingly, thereby reducing the effectiveness of SRS effectiveness verification. For example, in related technologies, for terminal devices in a radio resource control (RRC) inactive (RRC_INACTIVE) state, one longer extended discontinuous reception (eDRX) cycle can be set for the terminal device. The eDRX cycle can reach 2.9 hours. In this case, the RRM measurement process is reused before DRX, which inevitably reduces the effectiveness of SRS verification. In other words, in related technologies, the RRM measurement period may be too long, reducing the effectiveness of SRS verification. However, short RRM measurement cycles present several problems in the communication process. For example, a single RRM measurement cycle can be used for SRS verification. The RRM measurement cycle may be the same as, for example, the SRS transmission cycle. This results in RRM measurements being performed too frequently, thereby consuming more power from the terminal equipment.

[0074] This invention determines the measurement cycle of RRM measurement using a positioning server, thereby setting an appropriate RRM cycle to satisfy the effectiveness of SRS verification and reduce the power consumption of terminal equipment as much as possible. The measurement cycle may be determined based on one or more of the following: the paging detection cycle, the DRX cycle, and the positioning information of the terminal equipment.

[0075] The measurement period for RRM measurement may be shorter than the DRX period or the paging measurement period. For example, when a terminal device is in RRC_INACTIVE state and is configured in the DRX state, the terminal device can be set to an RRM measurement period shorter than the DRX period.

[0076] The positioning information of the terminal device can be found in the description above. Specifically, the positioning server can determine the measurement period for the RRM measurement indicated by the first information based on one or more pieces of information from the terminal device's movement status and location status.

[0077] When the RRM measurement cycle is reached, the RRM measurement is not necessarily performed. That is, the terminal device may or may not perform the RRM measurement. Whether or not to perform the RRM measurement may be indicated by the first information. For example, the first information may indicate one of the following: that the terminal device will perform the RRM measurement or will not perform the RRM measurement; that if the RRM measurement is necessary, the positioning server may transmit the first information; or that if the RRM measurement is not necessary, the positioning server may not transmit the first information.

[0078] The first information can indicate whether or not the terminal device reports the RRM measurement results. For the terminal device to report the RRM measurement results, it needs to request an uplink resource and perform uplink transmission, which consumes a significant amount of power. Under this application, the terminal device does not need to report the RRM measurement results. The terminal device can decide whether or not to report the RRM measurement results based on the instructions in the first information.

[0079] In one implementation, the first information may include a second measurement threshold. Based on the second measurement threshold, the terminal device can decide whether or not to perform an RRM report. The second measurement threshold may be a threshold for the difference between measured values ​​(e.g., the difference in RSRP). Whether or not the terminal device needs to report the measurement result of the RRM measurement (hereinafter abbreviated as RRM measurement result) may be determined based on the comparison result between the measurement result and the second measurement threshold. In some embodiments, if the difference between the measurement result and the result of a historical RRM measurement (hereinafter abbreviated as historical result) is greater than or equal to the second measurement threshold, the terminal device is required to report the measurement result. The historical result may be any RRM measurement result prior to the current RRM measurement. The difference between the measurement result and the historical result may include a value obtained by subtracting the historical result from the measurement result, and / or a value obtained by subtracting the measurement result from the historical result. For example, if the difference between the current RRM measurement result and the previous RRM measurement result is greater than or equal to the second measurement threshold, the terminal device can report the measurement result of the current RRM measurement.

[0080] The first information can indicate a first measurement threshold that triggers the terminal device to perform a first action. The first measurement threshold may include one or more of the measurement thresholds for RSRP, RSRQ, RSSI, and SINR. For example, if the first action relates to an RRM measurement, the terminal device may perform an RRM measurement if the measured value is greater than or equal to the first measurement threshold, but may not perform an RRM measurement if the measured value is less than the first measurement threshold.

[0081] In one embodiment, when a terminal device is located within a serving cell, the positioning server can use first information to notify the serving cell that the terminal device needs to perform RRM measurement again to determine how many relative cells within the serving cell's range the terminal device has measured. The relative cells may be the serving cell, or the serving cell and adjacent cells.

[0082] The first measurement threshold may be estimated by the positioning server based on information such as fingerprints.

[0083] If the first action relates to access by a terminal device, the first information may be used to indicate whether the terminal device needs access and one or more pieces of information about the reselected cell for the terminal device. In this case, the first information may be transmitted to the access network device corresponding to the reselected cell and / or serving cell.

[0084] Whether or not a terminal device needs to access a cell and / or which cell is re-selected for the terminal device may both be determined by the positioning server. The access network device corresponding to the terminal device's serving cell and / or re-selected cell can send a paging command. The paging command may be used for the paging terminal device to access the re-selected cell. The paging command may also be a core network (CN) paging command. In addition, in response to paging, the network side may instruct the terminal device to perform a first action (e.g., access or RRM measurement) via a physical downlink control channel (PDCCH) or a physical downlink shared channel (PDSCH).

[0085] Because the original access cell is far from the user, the new re-selected cell will forward the RAN on behalf of the original cell and initiate paging PDCCH, or the re-selected cell will transmit CN (Core network) paging.

[0086] In some embodiments, when a re-selected cell forwards a first signaling to a terminal device, the information such as the paging opportunity occupied by the signaling is the same as that of the original cell in the terminal device. The first signaling may be one or more of a paging message or a paging early indication (PEI).

[0087] A key difference from related technologies is that paging commands may be transmitted only by the re-selected cell and / or serving cell. In other words, it is not necessary for all cells in the tracking area to transmit paging commands. In this case, the positioning server or AMF can transmit paging only to the serving cell and / or the access network equipment corresponding to the re-selected cell.

[0088] In some embodiments, when a terminal device resides in or accesses a re-selected cell, the terminal device and / or the access network device corresponding to the newly resided or newly accessed cell (i.e., the re-selected cell) can report to the positioning server that the terminal device resides in or accesses the re-selected cell. The positioning server or AMF can notify the original cell that the terminal device resides in or accesses the re-selected cell. In response, the original cell can update the relevant information of the terminal device.

[0089] If the first operation relates to a transmit beam and / or receive beam, the first information is used to indicate beam information of terminal equipment and / or access network equipment. For example, if the first operation relates to a transmit beam, the first information may be used to indicate one or more of the beam information of the transmit beam of the access network equipment to the terminal equipment and beam information of the transmit beam of the access network equipment to the terminal equipment; or, for example, if the first operation relates to a receive beam, the first information may be used to indicate one or more of the beam information of the receive beam of the access network equipment to the terminal equipment and beam information of the receive beam of the access network equipment to the terminal equipment, and the beam information includes, but is not limited to, the angle and / or width of the beam corresponding to the beam information.

[0090] As mentioned above, the first action may also be related to the TA. If the terminal device is moving, the TA may become invalid. In this case, the terminal device can autonomously adjust the TA. For example, if the terminal device estimates the TA based on the downlink reference time difference, the terminal device can autonomously adjust the TA.

[0091] TA adjustments are always performed by terminal devices; in other words, network devices are not involved in TA adjustments. Consequently, it is difficult for network devices to determine whether or not the terminal device's TA has been adjusted, which prevents them from continuing to implement communication control afterward and can even lead to communication anomalies. For example, network devices may send a TA adjustment amount to terminal devices. If a terminal device has already adjusted its TA itself, the network device is unaware that the terminal device has adjusted its TA itself. Therefore, the TA adjustment amount sent from the network device is determined based on the previously unadjusted value, resulting in a TA anomaly.

[0092] This invention proposes that, when the first operation relates to a Terminal Address (TA), the first information may be used to indicate the estimated TA information of the terminal device estimated by the positioning server. In other words, the positioning server can estimate the TA status of the terminal device, and transmits the estimated TA status using the first information. The estimated TA information can be transmitted to access network devices, thereby allowing the network side to know the TA status of the terminal device.

[0093] The estimated TA information may include one or more of the following: an instruction on whether or not the terminal device adjusts the TA, or the TA value adjusted by the terminal device.

[0094] One understandable point is that when a terminal device autonomously adjusts the TA, it can transmit the status of that adjustment to network devices, thereby allowing network devices to know the TA update status. However, in order to acquire uplink resources and transmit the status of the terminal device autonomously adjusting the TA using those uplink resources, the terminal device needs to access a cell or enter a connected state. One understandable point is that this process consumes a large amount of resources. In this invention, the TA status of the terminal device is estimated by a positioning server, and the estimated information is transmitted to access network devices, thereby enabling the network side to know the TA status and reducing the power consumption of the terminal device.

[0095] Furthermore, it is complex for access network equipment to estimate the TA adjustment status of terminal equipment. For example, access network equipment can perform uplink SRS estimation. The transmission delay relative to the downlink RS of the SRS arrival time may include propagation delay and TA. Base stations cannot obtain information on whether terminal equipment is adjusting its TA. Therefore, this invention can simplify the step of the network side deciding whether to adjust the terminal equipment's TA by estimating the TA status of terminal equipment using a positioning server. For example, if access network equipment estimates the TA adjustment status of terminal equipment, the serving cell only estimates the signal arrival time. Even if the serving cell can estimate the time difference and the transmission / reception time difference, the serving cell cannot determine the location of the terminal equipment, and therefore cannot determine the transmission / reception delay, and thus the serving cell cannot estimate the TA. If t1 is the time when the base station receives the uplink pilot, t2 is the time when the base station transmits the downlink pilot, and T is the time difference between when the terminal equipment receives the downlink pilot and when it transmits the uplink pilot, then from the perspective of the base station, the propagation delay d including the TA effect between the base station and the terminal equipment may be d = (t1 - t2 - T) / 2.

[0096] One understandable point is that d includes the timing advance amount and the propagation delay between the base station and the terminal. The larger the timing advance amount, the smaller the value of d, and the smaller the propagation delay from the base station to the terminal, the smaller the value of d. Since d includes the timing advance amount and the propagation delay between the base station and the terminal, the base station obtains information on d and does not know whether the timing advance amount has been adjusted or not. However, the positioning server can estimate the location of the terminal device based on the reports from multiple base stations, thereby obtaining the propagation delay between the base station and the terminal. Each base station can report its own d value, and the positioning server decides whether to adjust the TA based on the propagation delay, d, and the TA notified from the previous serving cell, and then notifies the serving cell.

[0097] In some embodiments, an access network device corresponding to the cell to which a terminal device belongs (e.g., a serving cell) can report the TA value of the cell to which the terminal device belongs (the TA value configured on the terminal device by the access network device or the TA value of the terminal device before adjustment) to the positioning server. The access network device can also further notify the positioning server of one or more TA-related information, including the arrival time measured by each cell, the delay in the arrival time of the SRS relative to the transmission of the downlink RS, and the propagation delay estimated after removing the TA effect.

[0098] Based on the TA value and / or information related to the TA reported by the access network device, the positioning server can determine whether the terminal device has adjusted its TA. For example, based on the positioning information transmitted from each access network device, the positioning server can perform a location estimation on the terminal device and obtain the terminal device's new location (e.g., current location). Furthermore, the positioning server can calculate or estimate the estimated TA at the terminal device's new location. The positioning server can compare the estimated TA with the TA reported by the serving cell to determine whether the terminal device has adjusted its TA. If the positioning server determines that the terminal device has adjusted its TA, it can notify the access network device corresponding to the serving cell using the first information. The first information may indicate that the terminal device has adjusted its TA and / or an estimated value of the TA.

[0099] The positioning server determines whether the timing advance amount has changed based on the following formula: d - Δd - TA_old > n × ΔTA, where d is the propagation delay including TA reported from the serving cell, TA_old is the TA value in the cell of the terminal device, Δd is the propagation delay estimated by the positioning server, ΔTA is the digitization interval of TA, and n is a value greater than zero. n is predefined by standard and / or can be indicated by higher-layer signaling.

[0100] The following describes how terminal equipment autonomously adjusts the TA. Within the effective area, it is possible to determine whether the TA is effective or not based on changes in RSRP and / or downlink reference time. For example, network equipment can instruct terminal equipment on a first threshold for RSRP change and a second threshold for downlink reference time change. If the RSRP change is smaller than the first threshold and / or the downlink reference time change is smaller than the second threshold, the changes in downlink reference time and / or RSRP are considered to be very small. Small changes in downlink reference time and / or RSRP may be due to measurement errors or other circumstances, and therefore, terminal equipment does not need to adjust the TA value and obtain a new "effective TA value". Similarly, if the cause of the downlink reference time change and / or RSRP change is a change in the SSB measured by the terminal equipment, there is no need to require the terminal equipment to autonomously adjust the TA. However, if the RSRP change is greater than or equal to the first threshold and / or the downlink reference time change is greater than or equal to the second threshold, i.e., if the changes in downlink reference time and / or RSRP are large, terminal equipment can adjust the TA to compensate for the downlink sequence difference and thereby maintain a constant uplink sequence. This is because large changes in downlink reference time and / or RSRP can result in a significant transmission time difference between previously stationed cells and newly accessible cells, allowing terminal equipment to adjust the TA.

[0101] The RSRP mentioned above is obtained by measuring a reference signal. The positioning server notifies the access network device of one or more of the following: the reference signal of the measured RSRP, the cell to which the reference signal belongs, and the associated thresholds of the reference signal (first threshold and / or second threshold). The first threshold and / or second threshold may be adjusted by the network side to control the terminal device so that it maintains an appropriate or constant TA.

[0102] The first information can be provided using one or more methods from PEI, sequence, etc. By providing the first information to an inactive terminal device using the above methods, it is possible to prevent the terminal device from performing access or other operations, thereby reducing the power consumption of the terminal device.

[0103] Furthermore, terminal equipment or network equipment receiving the first information can refer to the proposal in the first information and perform the corresponding action. That is, the recipient of the first information may perform the corresponding action based on the first information, or it may perform the corresponding action without relying on the first information. For example, if the first information is used to indicate the measurement cycle of RRM measurement, the positioning server can notify the access network equipment of the proposed RRM measurement cycle based on the first information. The access network equipment can refer to this proposal when setting the RRM measurement cycle. The RRM measurement cycle actually configured in the access network equipment may be the same as or different from the one indicated in the first information.
