Description

Wireless positioning method and device

Technical Field

The present disclosure relates to the field of wireless communications, and more particularly, to a wireless positioning method and apparatus.

Background

The wireless location system estimates the location of the terminal device by detecting characteristic parameters (e.g., transmission time, incident angle, electric wave field strength, etc.) of a transmission signal between the mobile terminal device and the network device of a fixed location, thereby locating the terminal device. In some communication systems, such as the fifth generation mobile communication (5 th-generation, 5G) system, the radio resource control (radio resource control, RRC) state of the terminal device includes a CONNECTED state (rrc_connected), a deactivated state (rrc_inactive), and an IDLE state (rrc_idle). When the terminal device is in a connected state, an established communication link exists between the terminal device and the network device, through which data transmission can take place, and the network device can locate the terminal device based on the communication link. When the terminal equipment is in a deactivated state or an idle state, a communication link does not exist between the terminal equipment and the network equipment or the established communication link is interrupted, so that data transmission between the terminal equipment and the network equipment cannot be performed, and the network equipment cannot locate the terminal equipment.

Wireless location systems are applicable to a variety of location scenarios, one typical application scenario being a geofence (geo-fencing) scenario in the internet of things (Internet of things, ioT) field. The geofence can be understood as a preset wireless boundary, and when the terminal equipment enters or leaves the wireless boundary, an instant alarm can be triggered, so that monitoring of personnel or equipment in the geofence is realized. However, there is currently no solution in the prior art for locating a terminal device in an idle state or in a deactivated state. In addition, for the purpose of energy saving, the terminal device is generally in an idle state or a deactivated state, and is converted to a connection state when communication with the network device is needed, if the terminal device in the idle state or the deactivated state is converted to the connection state when positioning is performed each time, the signaling overhead of the terminal device is increased, and therefore the power consumption of the terminal device is larger.

Disclosure of Invention

The application provides a wireless positioning method and a wireless positioning device, which can position terminal equipment in an idle state or a deactivated state, reduce signaling overhead of the terminal equipment and power consumption of the terminal equipment, and further improve equipment and system performance.

In a first aspect, a wireless positioning method is provided, including: the terminal equipment obtains a first measurement result by measuring the signal quality of a service cell, wherein the terminal equipment is in an idle state or a deactivated state; if the first measurement result meets the first preset condition, the terminal equipment determines a second measurement result from the beam measurement results by executing beam measurement, wherein the second measurement result is used for indicating the measurement result of the first beam; if the first wave beam is contained in the preset wave beam list, the terminal equipment executes random access and enters a connection state; the terminal equipment sends alarm information to the first network equipment, wherein the alarm information is used for indicating the terminal equipment to cross a preset wireless boundary.

By the method, the terminal equipment can initiate signal measurement for positioning in the idle state or the deactivated state, and if the measurement result does not meet the alarm condition (namely the first preset condition and the preset beam list), the terminal equipment cannot enter the connected state, in other words, the terminal equipment in the idle state or the deactivated state cannot enter the connected state until the terminal equipment is about to cross the preset wireless boundary, and the terminal equipment which does not cross the preset wireless boundary does not need to enter the connected state. Therefore, the wireless positioning method provided by the application can position the terminal equipment in the idle state or the deactivated state, and reduce the signaling overhead of the terminal equipment and the power consumption of the terminal equipment, thereby improving the performance of the equipment and the system.

It should be understood that the above-described signal quality measurement of a serving cell by a terminal device may measure one or more of the following parameters: reference signal received power (reference signal receiving power, RSRP), reference signal received quality (reference signal receiving quality, RSRQ), received signal strength indication (received signal strength indicator, RSSI), which is not limited in this application.

It should also be understood that the terminal device performing beam measurement may be understood as a process in which the terminal device receives a reference signal transmitted by the first network device and performs measurement on the reference signal. The first network device may send a reference signal to the terminal device via a specific transmission beam, and the terminal device receives the reference signal via a specific reception beam, so as to determine the signal strength or signal quality of the reference signal received or measured by each reception beam, that is, a beam measurement result. The terminal device may determine a receiving beam with the strongest signal receiving strength or the best signal receiving quality from the beam measurement results, which may be referred to as a first beam in this application. Accordingly, the signal measurement result of the reference signal on the reception beam with the strongest signal reception strength or the best signal reception quality may be referred to as the measurement result of the first beam, i.e., the second measurement result. The reference signals may be, for example, channel state information reference signals (CSI-RS), UE-specific reference signals (UE-specific reference signal, DMRS), cell-specific reference signals (cell-specific reference signal, CRS), etc., which are not limited in this application.

With reference to the first aspect, in some implementations of the first aspect, if the terminal device moves close to the first network device, the first preset condition is that the first measurement result is greater than or equal to a first threshold, and the preset beam list is a first preset beam list; or if the terminal equipment moves away from the first network equipment, the first preset condition is that the first measurement result is smaller than or equal to the second threshold value, and the preset beam list is a second preset beam list.

It should be understood that the first preset conditions corresponding to different scenes may be different, and the preset beam list corresponding to different scenes may be different. In the application, the terminal device can know whether the terminal device moves in a direction approaching to the first network device or moves in a direction far away from the first network device according to a plurality of measurement results of signal strength or signal quality of the serving cell, so that a corresponding preset condition and a preset beam list are selected for judgment.

With reference to the first aspect, in certain implementation manners of the first aspect, the wireless positioning method further includes: the terminal equipment receives a position measurement request from the second network equipment; and the terminal equipment sends the first measurement result and the second measurement result to the second network equipment according to the position measurement request.

The first measurement result and the second measurement result may be used to calculate the position of the terminal device. The second network device may calculate the position of the terminal device by itself after receiving the first measurement result and the second measurement result, or the second network device may send the first measurement result and the second measurement result to other network devices, and after calculating the position of the terminal device, the other network devices send the calculation result to the second network device. It should be understood that the second network device may be a location management function LMF network element, and may also be a local location management function (local location management function, LLMF) deployed on a network device such as a base station; the other network device may be a location measurement unit (location measurement unit, LMU) or a location management component (location management component, LMC) in a 5G NR system.

In one possible implementation, the terminal device is switched from the connected state to the idle state or the deactivated state, so that the network side stores the historical location information of the terminal device, and the second network device may initiate a request to locate the terminal device according to the stored historical location information about the terminal device.

With reference to the first aspect, in certain implementations of the first aspect, the location measurement request is sent by a fifth generation mobile communication system 5G gateway or an access and mobility management function AMF network element to the second network device.

The wireless positioning method can be initiated by the terminal equipment and can also be positioned by the terminal equipment according to the request of the network side. For example, the 5G gateway or the access and mobility management function AMF network element may send the location measurement request to the second network device, which in turn sends the location measurement request to the terminal device. It should be noted that, the present application only takes the 5G gateway or the AMF network element with access and mobility management function as an example, and network elements with functions similar to those of the 5G gateway or the AMF network element with access and mobility management function in the 5G communication system or the next generation mobile communication system thereof are all included in the protection scope of the present application.

With reference to the first aspect, in certain implementation manners of the first aspect, the wireless positioning method further includes: and the terminal equipment calculates the position of the terminal equipment according to the first measurement result and the second measurement result. That is, in case the terminal device initiates positioning by itself, the terminal device may also calculate its own position according to the first measurement result and the second measurement result.

With reference to the first aspect, in certain implementation manners of the first aspect, the wireless positioning method further includes: the terminal equipment receives preset information sent by the first network equipment, wherein the preset information carries a first preset condition and a preset beam list.

The first preset condition and the preset beam list may be obtained by the terminal device from preset information sent by the first network device. In one possible implementation, the preset information may be system information, such as SSB. It should be understood that, in addition to the first preset condition and the preset beam list, the preset information sent by the first network device may further include other preset conditions and other beam lists, which is not limited in this application. It should also be understood that the preset condition and the beam list included in the preset information sent by the first network device are preset conditions and beam lists corresponding to the first network device.

The preset information includes a first threshold and a second threshold, and the terminal device may select the corresponding threshold and the preset condition according to the movement condition of the terminal device, that is, if the terminal device moves close to the first network device, the terminal device may select the first threshold, and further determine that the first preset condition is greater than or equal to the first threshold, and if the terminal device moves far away from the first network device, the terminal device may select the second threshold, and further determine that the first preset condition is less than or equal to the second threshold.

With reference to the first aspect, in certain implementation manners of the first aspect, the method further includes: the terminal equipment determines a first preset condition from a plurality of preset conditions according to the current service type, the plurality of preset conditions correspond to a plurality of different service types, and the first preset condition corresponds to the current service type.

It is contemplated that the system may preset multiple geofences simultaneously, or that the shape of the geofences may be varied, i.e., the above-described preset wireless boundaries may be multiple, and the preset wireless boundaries may vary. The preset conditions corresponding to different preset wireless boundaries are different, and the different preset wireless boundaries correspond to different service types, namely, the different service types correspond to different preset conditions. The terminal device may select, according to the current service type, a first preset condition corresponding to the current service type from a plurality of preset conditions.

In one possible implementation manner, the plurality of preset conditions may be carried in preset information sent by the first network device.

By setting different preset conditions for different service types, the wireless positioning method can be suitable for various different scenes, for example, a plurality of preset geofences with different shapes and different ranges are set, and the positioning flexibility is improved.

With reference to the first aspect, in certain implementations of the first aspect, the random access is a contention-based random access or a two-step random access. That is, the manner in which the terminal device performs the random access to enter the connected state may be a contention-based random access, or a simplified contention-based random access, that is, a two-step random access, which is not limited in this application.

In a second aspect, another wireless positioning method is provided, including: the terminal equipment obtains a first measurement result by measuring the signal quality of a service cell, and is in an idle state or a deactivated state; if the first measurement result meets the first preset condition, the terminal equipment determines a second measurement result from the beam measurement results by executing beam measurement, wherein the second measurement result is used for indicating the measurement result of the first beam; if the first beam is included in the preset beam list, the terminal device sends a random access request to the first network device, wherein the random access request carries a first preamble, and the first preamble is associated with the first beam.

In the above wireless positioning method, when the terminal device needs to initiate an alarm, the terminal device may send a random access request by using the preamble for positioning, and the first network device may learn that the terminal device crosses the preset wireless boundary after receiving the preamble for positioning. In this way, the terminal device only needs to send the preamble for positioning to initiate a random access request, informing the first network device that there is information that the terminal device is out of range, and the related steps of the subsequent random access may not be performed. The terminal equipment may be successfully accessed in a random manner and may fail in a random access manner, and the method is not limited herein, and does not affect the wireless positioning method provided by the application. Therefore, the wireless positioning method provided by the application can implicitly alarm the network equipment under the condition that the terminal equipment in the idle state or the deactivated state does not enter the random access connection state, and the method is beneficial to reducing the signaling overhead of the terminal equipment and the power consumption of the terminal equipment, so that the equipment and the system performance are improved.

It should be understood that the first preamble in this application is a preamble associated with the first beam for positioning. The first network device, upon receiving the first preamble, may be capable of determining that there is a terminal device crossing a preset wireless boundary based on identifying that the first preamble is a preamble for positioning. However, the first network device cannot determine in particular which terminal device crosses the preset radio boundary.

In one possible implementation, in a subsequent random access procedure, the terminal device may send an Identification (ID) of the terminal device to the first network device, so that the first network device may identify the terminal device crossing the preset wireless boundary.

In one possible implementation manner, the first preamble used for positioning may be to add or subtract a part of bits from an existing preamble, or the first preamble carries a special identifier. Wherein an increased or decreased portion of bits, or a special identification, is used to indicate the first beam.

With reference to the second aspect, in some implementations of the second aspect, if the terminal device moves close to the first network device, the first preset condition is that the first measurement result is greater than or equal to a first threshold, and the preset beam list is a first preset beam list; or if the terminal equipment moves away from the first network equipment, the first preset condition is that the first measurement result is smaller than or equal to a second threshold value, and the preset beam list is a second preset beam list.

With reference to the second aspect, in certain implementations of the second aspect, the location measurement request is sent by a fifth generation mobile communication system 5G gateway or an access and mobility management function AMF network element to the second network device. It should be noted that, the present application only takes the 5G gateway or the AMF network element with access and mobility management function as an example, and network elements with functions similar to those of the 5G gateway or the AMF network element with access and mobility management function in the 5G communication system or the next generation mobile communication system thereof are all included in the protection scope of the present application.

(1) The LMF network element may interact with the ng-eNB or the gNB through some specific positioning protocol, such as NR positioning protocol (NR positioning protocol annex, NRPPa) messages, for example, positioning reference signal (positioning reference signal, PRS) configuration information, sounding reference signal (sounding reference signal, SRS) configuration information, cell timing, cell location information, and so on, between the LMF network element and the ng-eNB or the gNB.

(2) And the LMF network element and the UE transmit the information such as UE capability information, auxiliary information, measurement results and the like through an LTE positioning protocol (LTE positioning protocol, LPP) message.

It should be understood that the information transmission between the LMF network element and the ng-eNB or the gNB, and the information transmission between the LMF network element and the UE are all forwarded through the intermediate device. Taking an example that the UE sends the measurement result to the LMF network element, the UE may send the measurement result to the gNB first, where the gNB and the AMF network element forward the measurement result, so that the LMF network element receives the measurement result sent by the UE. Illustratively, the UE sends an LPP message to the LMF network element, which may be transmitted via an LPP protocol data unit (protocol data unit, PDU), specifically may include three steps: (1) The UE includes the LPP PDU in a payload container of a first message (e.g., UL NAS Transport message), and then the UE sends the first message to the ng-eNB or the gNB in a second message (e.g., RRC UL Information Transfer message); (2) The ng-eNB or the gNB forwards the first message to the AMF network element through a third message (such as NGAP Uplink NAS Transport message); (3) The AMF network element acquires the LPP PDU from the first message and sends the LPP PDU to the LMF network element, wherein the LPP PDU is contained in an N1 message container.

The UE and the NG-eNB are connected through an LTE-Uu interface, the UE and the gNB are connected through an NR-Uu interface, the gNB and the NG-eNB are connected through an Xn interface, the gNB and the AMF are connected through an NG Control plane (NG-C) interface, the NG-eNB and the AMF are connected through an NG-C interface, and the AMF and the LMF are connected through a NLs interface.

Optionally, the communication system 200 may further include a 5G core network location service (5G core networklocation services,5GC LCS) entity, where the 5GC LCS entity corresponds to a gateway and may be connected to other control entities. The AMF network element may be directly or indirectly connected to the 5GC LCS entity through other interfaces.

It should be understood that fig. 1 and 2 are only schematic diagrams, and that other devices not shown may be included in the communication systems 100 and 200. The number of terminal devices and access networks included in the communication system 100 and the communication system 200 is not limited in the embodiments of the present application.

To facilitate an understanding of the embodiments of the present application, the terms referred to in this application are first briefly described.

1. RRC state

Taking the NR system as an example, the radio resource control states of the terminal device include a connection state (rrc_connected), a deactivation state (rrc_inactive), and an IDLE state (rrc_idle). These three states are described below, respectively.

(1) When the terminal equipment is in a connection state, the terminal equipment, the access network equipment and the core network equipment are all established with links, and when data arrives at the network, the core network equipment and the access network equipment can directly transmit the data to the terminal equipment.

(2) When the terminal device is in a deactivated state, it is explained that the terminal device has previously established a link with the access network device and the core network device, but the link between the terminal device and the access network device is released. Although the link is released, the access network device needs to save the context of the terminal device, and when data needs to be transmitted, the access network device can quickly restore the released link according to the context of the terminal device.

(3) When the terminal equipment is in an idle state, no link exists between the terminal equipment and the access network equipment and between the terminal equipment and the core network equipment, and when data needs to be transmitted, the link from the terminal equipment to the access network equipment and the core network equipment needs to be established.

From the above, the deactivation state can only be converted by RRC connection release message when the terminal device is in the connected state, and the idle state can be converted when the terminal device is in the connected state, or the terminal device is in the idle state when it is in the self-camping cell.

When the terminal device is in an idle state or a deactivated state, the following operations may be performed when the terminal device camps on a cell:

(1) Receiving a system message under a current public land mobile network (public land mobile network, PLMN);

(2) When the terminal device wishes to establish an RRC connection or resume a suspended RRC connection, the terminal device may initiate random access in the camping cell;

(3) If the network device needs to send a message or transmit data to the registered terminal device, the network device can send a paging message to the terminal device, and the terminal device can receive the paging message and respond;

(4) The terminal equipment may receive the earthquake and tsunami warning system (earthquake and tsunami warning system, ETWS) and the commercial mobile alert system (commercial mobile alert system, CMAS) notifications.

It will be appreciated that the names of the RRC states described above are merely illustrated by way of example with NR and should not be construed as limiting the present application in any way. The present application does not exclude that other possible names are defined in existing or future protocols instead of names of RRC states in the above-mentioned NR, but with the same or similar properties.

2. Random access

Random access refers to a procedure before a terminal device transmits a random access preamble (preamble) to attempt to access a network and establish a basic signaling connection with the network. It should be understood that random access is initiated by a terminal device in an idle state or a deactivated state, and mainly obtains uplink synchronization with an access network device and applies for uplink resources. The random access is mainly applied to an initial access period before the RRC connection establishment and an RRC connection re-establishment period.

Random access is classified into contention-based random access and non-contention-based random access.

In non-contention based random access, the terminal device may initiate random access by using a random access code allocated to itself by the access network device, where the non-contention based random access includes two steps of sending a random access request by the terminal device and sending a random access response by the access network device.

In contention-based random access, a terminal device may randomly select a random access preamble to initiate random access, which may cause a problem of resource contention because the random access preamble may be selected by a plurality of different terminal devices in one resource pool. In this case, the access network device needs to send a contention resolution message to the terminal device. Thus, the contention-based random access procedure includes the following four steps:

step one, the terminal device randomly selects a random access preamble, and sends a random access request on a physical random access channel (physical random access channel, PRACH), which may be referred to as message 1 (msg 1).

Step two, the access network device detects the random access request carrying the random access preamble, and then sends a random access response, which may be called message 2 (msg 2). Illustratively, the random access response may include a number of the random access preamble received by the access network device, a time adjustment amount of the random access preamble received by the access network device, and information for indicating an uplink resource location allocated by the access network device for the terminal device.

Step three, the terminal equipment receives the random access response sent by the access network equipment, and sends an uplink message (namely a physical uplink shared channel (physical uplink shared channel, PUSCH)) on an uplink resource indicated by the random access response, which can be called message 3 (msg 3), wherein the uplink message can comprise a unique identifier (such as a temporary mobile subscriber identity (temporary mobile subscriber identity, TMSI)) or a corresponding random access identifier of the terminal equipment;

step four, the access network device receives the uplink message sent by the terminal device, and sends a contention resolution message to the terminal device with successful access, which may be called message 4 (msg 4), where the contention resolution message may include a unique ID (e.g. TMSI) or a corresponding random access identifier of the terminal device with successful access.

It should be understood that the number of the terminal devices may be one or more, and when a plurality of terminal devices simultaneously select the same random access preamble for random access, contention may be caused, and then the access network device needs to perform contention resolution through the four steps.

The above-described contention-based random access may also be referred to as a four-step random access (4-step RACH). In order to reduce the signaling overhead and delay associated with random access in the above procedure, the above contention-based four-step random access may be reduced to a two-step random access (2-step RACH). The two-step random access is suitable for small data transmission and/or in the unlicensed band scenario. Specifically, the two-step random access mainly includes two steps of a terminal device sending a message a (msgA) to an access network device and an access network device sending a message B (msgB) to the terminal device. Wherein msgA may include messages in msg 1 and msg3 and msgB may include messages in msg 2 and msg 4. Illustratively, the msgA may include a random access request carrying a random access preamble, a message for requesting establishment of a connection, reestablishment of a connection, or restoration of a connection, a message for requesting on-demand system information, a cell-radio network temporary identity (cell-radio network temporary identity, C-RNTI), etc.; timing advance, C-RNTI, etc. may be included in the msgB.

Considering that there are only two steps in non-contention based random access, it should be noted that the two-step random access in the embodiments of the present application refers to two-step random access based on contention.

3. Geofence (geo-fencing)

Geofencing is a new application of position location services (location based services, LBS), which is a geographical boundary closed with a virtual fence that can trigger an immediate alarm when a terminal device enters or leaves the geographical boundary, enabling the monitoring of personnel within the geofence.

The geofence can provide intelligent safety protection for various large scenes, for example, asset positions can be monitored in real time in an industrial park, safety areas and dangerous ranges can be defined through the geofence in a kindergarten or a nursing home, intelligent unlocking and the like can be facilitated in the intelligent home industry through near-field identity recognition.

It should be appreciated that the shape of the geofence may be circular, oval, polygonal, etc., as embodiments of the present application are not limited in this regard.

The positioning of the terminal device by the wireless positioning system is to estimate the position of the terminal device by detecting the characteristic parameters (such as transmission time, incidence angle, electric wave field intensity, etc.) of the transmission signal between the terminal device and the network device at a fixed position. When the terminal equipment is in a connection state, an established link exists between the terminal equipment and the network equipment, data transmission can be performed, and the network equipment can position the terminal equipment. When the terminal equipment is in a deactivated state or an idle state, a link does not exist between the terminal equipment and the network equipment, and data transmission cannot be performed, so that positioning cannot be performed. In some special scenarios, for example, a geofence (geo-fence) scenario in the internet of things (Internet of things, ioT) field, for the purpose of energy saving, a terminal device is generally in an idle state or a deactivated state, and is converted to a connection state when communication is needed, if the terminal device in the idle state or the deactivated state is converted to the connection state when each positioning is performed, the positioning is performed again, which results in a larger signaling overhead of the terminal device, and thus, a larger power consumption of the terminal device.

In view of this, the present application provides a wireless positioning method and apparatus, which can position a terminal device in an idle state or a deactivated state, and reduce signaling overhead of the terminal device and power consumption of the terminal device, thereby improving device and system performance.

Before introducing the methods provided herein, the following description is made.

First, in the present application, "indication" may include direct indication and indirect indication, and may include explicit indication and implicit indication. The information indicated by a certain information (such as the alarm information described below) is called to-be-indicated information, and in a specific implementation process, there may be various ways of indicating the to-be-indicated information, for example, but not limited to, the to-be-indicated information may be directly indicated, for example, the to-be-indicated information itself or an index of the to-be-indicated information, etc. The information to be indicated can also be indicated indirectly by indicating other information, wherein the other information and the information to be indicated have an association relation. It is also possible to indicate only a part of the information to be indicated, while other parts of the information to be indicated are known or agreed in advance. For example, the indication of the specific information may also be achieved by means of a pre-agreed (e.g., protocol-specified) arrangement sequence of the respective information, thereby reducing the indication overhead to some extent.

Second, in the embodiments shown below, terms and english abbreviations, such as medium access control element (MAC-CE), radio resource control (radio resource control, RRC), reference signal received power (reference signal received power, RSRP), channel state information reference signal (channel state information-reference signal, CSI-RS), synchronization signal (synchronization signal, SS), physical broadcast channel (physical broadcast channel, PBCH), synchronization signal block (SS/PBCH block, SSB), etc., are given as exemplary examples for convenience of description, and should not constitute any limitation to the present application. This application does not exclude the possibility of defining other terms in existing or future protocols that perform the same or similar functions.

Third, the first, second and various numerical numbers in the embodiments shown below are merely for convenience of description and are not intended to limit the scope of the embodiments of the present application. For example, different thresholds, different preset conditions, different preset beam lists, etc. are distinguished.

Fourth, in the embodiments shown below, "pre-fetching" may include signaling by the network device or pre-defining, e.g., protocol definition. The "pre-defining" may be implemented by pre-storing corresponding codes, tables or other manners that may be used to indicate relevant information in devices (including, for example, terminal devices and network devices), and the application is not limited to a specific implementation manner thereof.

Fifth, the "protocol" referred to in the embodiments of the present application may refer to a standard protocol in the field of communications, and may include, for example, an LTE protocol, an NR protocol, and related protocols applied in a future communication system, which is not limited in this application.

Various embodiments provided herein are described in detail below in conjunction with fig. 3-7.

In the embodiments of the present application, a terminal device and a network device are described as examples, it should be understood that the terminal device may be replaced by a device or a chip capable of implementing a function similar to that of the terminal device, and the network device may also be replaced by a device or a chip capable of implementing a function similar to that of the network device.

Fig. 3 is a schematic flowchart of a wireless positioning method 300 according to an embodiment of the present application. The method 300 may be applied to the communication system 100 shown in fig. 1, and may also be applied to the communication system 200 shown in fig. 2, which is not limited in this embodiment of the present application. The method 300 may include:

s310, the terminal equipment measures the signal quality of the service cell to obtain a first measurement result, wherein the terminal equipment is in an idle state or a deactivated state;

s320, if the first measurement result meets the first preset condition, the terminal equipment performs beam measurement and determines a second measurement result from the beam measurement results, wherein the second measurement result is used for indicating the measurement result of the first beam;

S330, if the first wave beam is contained in the preset wave beam list, the terminal equipment executes random access and enters a connection state;

s340, the terminal device sends alarm information to the first network device, wherein the alarm information is used for indicating the terminal device to cross the preset wireless boundary.

In the embodiment of the application, the terminal device is in an idle state or a deactivated state, and cannot send information to the network side, but the terminal device may receive a signal transmitted by the network side. In step S310, the terminal device may receive a signal of the serving cell, and measure signal quality to obtain a first measurement result. The first measurement result represents a signal measurement result of the terminal device for the serving cell, and may be specifically represented by a numerical value. It should be understood that the above terminal device measures the signal quality of the serving cell, and may measure one or more of the following parameters: reference signal received power (reference signal receiving power, RSRP), reference signal received quality (reference signal receiving quality, RSRQ), received signal strength indication (received signal strength indicator, RSSI), which is not limited in this embodiment.

After obtaining the first measurement result, the terminal device may determine whether the first measurement result meets a first preset condition. The first preset condition may be obtained in advance by the terminal device. Illustratively, the first preset condition may be protocol defined; or, the first preset condition may be obtained by the terminal device from preset information sent by the first network device. For example, the first network device may send the preset information (e.g. system information), so that the terminal device in the idle state or the deactivated state may obtain the preset information, and further obtain the first preset condition from the preset information. If the first measurement result meets the first preset condition, the terminal device continues to perform beam measurement, that is, step S320 is executed; if the first measurement result does not meet the first preset condition, the terminal device can terminate the measurement and end the positioning process.

In step S320, the terminal device performing beam measurement may be understood as a process in which the terminal device receives a reference signal sent by the first network device and performs measurement on the reference signal. The first network device may send a reference signal to the terminal device via a specific transmission beam, and the terminal device receives the reference signal via a specific reception beam, so as to determine the signal strength or signal quality of the reference signal received or measured by each reception beam, that is, a beam measurement result. The terminal device may determine a receiving beam with the strongest signal receiving strength or the best signal receiving quality from the beam measurement results. Accordingly, the signal measurement result of the reference signal on the reception beam with the strongest signal reception strength or the best signal reception quality may be referred to as the measurement result of the first beam, i.e., the second measurement result. The reference signals may be, for example, channel state information reference signals (CSI-RS), UE-specific reference signals (UE-specific reference signal, DMRS), cell-specific reference signals (cell-specific reference signal, CRS), etc., which are not limited in this embodiment.

After the terminal device obtains the second measurement result, it may determine whether the first beam corresponding to the second measurement result belongs to a preset beam list. The preset beam list may also be pre-acquired by the terminal device. Illustratively, the preset beam list may be protocol defined; alternatively, the preset beam list may be obtained by the terminal device from preset information sent by the first network device. Similar to the first preset condition, the description is omitted here. If the first beam is included in the preset beam list, the terminal device initiates random access, and enters a connection state, that is, continues to execute step S330; if the first beam is not included in the preset beam list, the terminal device may end the positioning process.

It should be understood that the first preset condition and the preset beam list are both set according to a preset wireless boundary, and that the first beam is included in the preset beam list, that is, indicates that the terminal device is about to cross the preset wireless boundary, and needs to alarm to the network device. Since the terminal device is in the idle state or the deactivated state, the terminal device needs to perform step S330, enter the connected state, and establish a communication link capable of performing data transmission, so as to send the alarm information to the network device related to the preset wireless boundary. It should also be understood that the manner in which the terminal device performs the random access to enter the connected state may be the contention-based random access described above, or the simplified contention-based random access, that is, the two-step random access, which is not limited in the embodiment of the present application.

After the terminal device enters the connected state, the terminal device may perform step S340, i.e. send an alarm message to the first network device, indicating that the terminal device crosses a preset wireless boundary. The alert information may be, for example, 1 bit information, specifically, 0 or 1, or other forms of information, which is not limited in this application.

By the method, the terminal equipment can initiate signal measurement for positioning in the idle state or the deactivated state, and if the measurement result does not meet the alarm condition (namely the first preset condition and the preset beam list), the terminal equipment cannot enter the connected state, in other words, the terminal equipment in the idle state or the deactivated state cannot enter the connected state until the terminal equipment is about to cross the preset wireless boundary, and the terminal equipment which does not cross the preset wireless boundary does not need to enter the connected state. Therefore, the wireless positioning method can position the terminal equipment in the idle state or the deactivated state, reduce signaling overhead of the terminal equipment and power consumption of the terminal equipment, and improve equipment and system performance.

In the method 300, the cell signal measurement in step S310 is at a low frequency (corresponding to a low frequency cell), and the beam measurement in step S320 is at a high frequency (corresponding to a high frequency cell), and the operating frequency of the low frequency cell is typically less than a certain threshold (e.g., less than 6 GHz), and the operating frequency of the high frequency cell is between two thresholds (e.g., 24.25GHz to 52.6 GHz). Therefore, depending on whether the serving cell of the terminal device is capable of operating at low and high frequencies, the following two cases can be mentioned:

Case 1, the serving cell, can operate at both low and high frequencies, also known as high frequency cell and low frequency cell co-sited.

For case 1, the network devices corresponding to the low frequency cell and the high frequency cell are both first network devices (for example, may be regarded as a macro base station), and the terminal device may complete measurement of signal quality and beam measurement of the serving cell by receiving the signal of the first network device.

Case 2, the serving cell can only operate at low frequencies, also called high frequency cell and low frequency cell non-co-sites.

For case 2, the network device corresponding to the low-frequency cell is a first network device (for example, may be regarded as a macro base station), and the high-frequency cell may have one or more other network devices (for example, may be regarded as small base stations within the coverage area of the macro base station) respectively, and when the terminal device performs beam measurement, it is required to receive reference signals of the one or more other network devices, so as to obtain measurement results of corresponding beams. Unlike case 1, the information of the beams in the preset beam list needs to be transmitted through signaling interaction between the plurality of network devices in case 2.

Taking the macro base station and the small base stations as examples, one or more small base stations can send respective preset beam lists to the macro base station, for example, the preset beam list of the small base station 1 is {2,3}, the preset beam list of the small base station 2 is {5,6}, the preset beam category of the small base station 3 is {6,7}, and the macro base station receives the preset beam list sent by each small base station and performs summarization to obtain a final preset beam list {2,3,5,6,7}.

It should be understood that in case 2, the signaling interaction between the plurality of network devices may be performed before the terminal device performs beam measurement, specifically, before the terminal device performs signal quality measurement of the serving cell, or after the terminal device performs signal quality measurement of the serving cell, which is not limited in this embodiment of the present application.

As an optional embodiment, if the terminal device moves close to the first network device, the first preset condition is that the first measurement result is greater than or equal to a first threshold value, and the preset beam list is a first preset beam list; or if the terminal equipment moves away from the first network equipment, the first preset condition is that the first measurement result is smaller than or equal to the second threshold value, and the preset beam list is a second preset beam list.

It should be understood that the first preset conditions corresponding to different scenes may be different, and the preset beam list corresponding to different scenes may be different. In the embodiment of the present application, the terminal device may learn, according to a plurality of measurement results of signal strength or signal quality of the serving cell, whether the terminal device moves in a direction approaching to the first network device or moves in a direction departing from the first network device, so as to select a corresponding preset condition and a preset beam list for determining.

For ease of understanding, embodiments of the present application are described in detail below in connection with the geofence scenario illustrated in FIG. 4.

Since the first threshold and the second threshold are for the same network device, the first threshold and the second threshold corresponding to different network devices may be different, and in order to avoid ambiguity, the description is made below by using the first threshold of the network device and the second threshold of the network device. Similarly, the first preset beam list and the second preset beam list are also for the same network device, and the first preset beam list and the second preset beam list corresponding to different network devices may be different, so as to avoid ambiguity, and the following description is made by adopting a mode of the first preset beam list of the network device and the second preset beam list of the network device.

In case 1, the first network device is a network device a, where the network device a is located outside the preset wireless boundary as shown in the figure.

(1) The terminal device starts to move within the preset wireless boundary, i.e. the terminal device will cross the preset wireless boundary from inside to outside.

In this case, the terminal device moves close to the network device a, the first preset condition is that the first measurement result is greater than or equal to a first threshold of the network device a, and the preset beam list is a first preset beam list of the network device a. That is, the terminal device is closer to the network device a, the signal quality is stronger, and when the signal quality is strong to the signal strength corresponding to the inner boundary, the terminal device can be considered to meet the first preset condition, so as to trigger the beam measurement of the terminal device. Optionally, the first threshold of the network device a is a signal strength value of the network device a corresponding to the inner boundary in fig. 4, but the embodiment of the present application is not limited thereto. Fig. 4 shows a first preset beam list {1,2,3,4} of the network device a, and assuming that a second measurement result obtained by the terminal device performing beam measurement is a measurement result corresponding to the beam 2, since the beam 2 belongs to the first preset beam list of the network device a, the terminal device may perform random access, enter a connection state, and send alarm information to the network device a. Assuming that the second measurement result obtained by the terminal device performing the beam measurement is the measurement result corresponding to the beam 10, since the beam 10 does not belong to the first preset beam list of the network device a, the terminal device may not initiate random access and may continue to be in the idle state or the deactivated state.

(2) The terminal device starts to move outside the preset wireless boundary, i.e. the terminal device will cross the preset wireless boundary from outside to inside.

In this case, the terminal device moves away from the network device a, the first preset condition is that the first measurement result is less than or equal to the second threshold of the network device a, and the preset beam list is a second preset beam list of the network device a. That is, the terminal device is farther from the network device a, the signal quality is weaker, and when the signal quality is weaker to the signal strength corresponding to the outer boundary, the terminal device can be considered to meet the first preset condition, so that the beam measurement of the terminal device is triggered. Optionally, the second threshold of the network device a is a signal strength value of the network device a corresponding to the outer boundary in fig. 4, but the embodiment of the present application is not limited thereto. Fig. 4 shows a second preset beam list {1,2,3,4,5} of the network device a. Assuming that the second measurement result obtained by the terminal device performing the beam measurement is the measurement result corresponding to the beam 2, since the beam 2 belongs to the second preset beam list of the network device a, the terminal device may perform random access, enter a connection state, and transmit alarm information to the network device a. Assuming that the second measurement result obtained by the terminal device performing the beam measurement is the measurement result corresponding to the beam 10, since the beam 10 does not belong to the second preset beam list of the network device a, the terminal device may not initiate random access and may continue to be in the idle state or the deactivated state.

Considering the location of the network device a, the signal strength corresponding to the outer boundary is stronger than the signal strength corresponding to the inner boundary, and therefore, the second threshold of the network device a is greater than the first threshold of the network device a. In fig. 4, the first preset beam list and the second preset beam list of network device a are different.

In case 2, the first network device is network device B in fig. 4, where the network device B is located inside the preset wireless boundary as shown in the figure.

In this case, the terminal device moves away from the network device B, the first preset condition is that the first measurement result is less than or equal to the second threshold of the network device B, and the preset beam list is a second preset beam list of the network device B. That is, the terminal device is farther from the network device B, the signal quality is weaker, and when the signal quality is weaker to the signal strength corresponding to the inner boundary, the terminal device can be considered to meet the first preset condition, so as to trigger the beam measurement of the terminal device. Optionally, the second threshold of the network device B is a signal strength value of the network device B corresponding to the outer boundary in fig. 4, but the embodiment of the present application is not limited thereto. Fig. 4 shows a second preset beam list {9, 10,11,12,13,14} of the network device B, and assuming that the second measurement result obtained by the terminal device performing the beam measurement is the measurement result corresponding to the beam 12, since the beam 2 belongs to the second preset beam list of the network device B, the terminal device may perform random access, enter a connection state, and transmit alarm information to the network device B. Assuming that the second measurement result obtained by the terminal device performing the beam measurement is the measurement result corresponding to the beam 5, since the beam 5 does not belong to the second preset beam list of the network device B, the terminal device may not initiate random access and may continue to be in the idle state or the deactivated state.

In this case, the terminal device moves close to the network device B, the first preset condition is that the first measurement result is greater than or equal to a first threshold of the network device B, and the preset beam list is a first preset beam list of the network device B. That is, the terminal device is closer to the network device B, the signal quality is stronger, and when the signal quality is stronger than the signal strength corresponding to the outer boundary, the terminal device can be considered to meet the first preset condition, so as to trigger the beam measurement of the terminal device. Optionally, the first threshold of the network device B is a signal strength value of the network device B corresponding to the outer boundary in fig. 4, but the embodiment of the present application is not limited thereto. Fig. 4 shows a first preset beam list {9, 10,11,12,13,14} of the network device B, and assuming that a second measurement result obtained by the terminal device performing beam measurement is a measurement result corresponding to the beam 12, since the beam 12 belongs to the first preset beam list of the network device B, the terminal device may perform random access, enter a connection state, and transmit alarm information to the network device B. Assuming that the second measurement result obtained by the terminal device performing the beam measurement is the measurement result corresponding to the beam 5, since the beam 5 does not belong to the first preset beam list of the network device B, the terminal device may not initiate random access and may continue to be in the idle state or the deactivated state.

Considering the location of the network device B, the signal strength corresponding to the outer boundary is stronger than the signal strength corresponding to the inner boundary, and thus the second threshold of the network device B is greater than the first threshold of the network device B. In fig. 4, the first preset beam list and the second preset beam list of the network device B are the same.

It should be understood that the foregoing merely exemplifies two possible cases, where the preset condition of each cell and the corresponding preset beam list may be determined by the network device of the cell in combination with all the beams and the preset radio boundaries, and the selection of the preset condition and the corresponding preset beam list is not limited in the embodiments of the present application.

As an optional embodiment, the above wireless positioning method further includes: the terminal equipment receives a position measurement request from the second network equipment; and the terminal equipment sends the first measurement result and the second measurement result to the second network equipment according to the position measurement request.

The first measurement result and the second measurement result may be used to calculate the position of the terminal device. After receiving the first measurement result and the second measurement result, the second network device may calculate the position of the terminal device by itself, or the second network device may also send the first measurement result and the second measurement result to other network devices, where the other network devices may calculate the position of the terminal device and send the calculation result to the second network device. It should be understood that the second network device may be a location management function LMF network element, and may also be a local location management function (local location management function, LLMF) deployed on a network device such as a base station; the other network device may be a location measurement unit (location measurement unit, LMU) or a location management component (location management component, LMC) in a 5G NR system.

It should be understood that, the above information transmission between the terminal device and the second network device, such as the transmission of the location measurement request, the first measurement result and the second measurement result, may be directly sent by the terminal device to the second network device, or may be sent by the terminal device to the second network device through the first network device and other network devices, which is not limited in this embodiment of the present application.

As an alternative embodiment, the location measurement request is sent to the second network device by a fifth generation mobile communication system 5G gateway or an access and mobility management function AMF network element.

The wireless positioning method 300 can be initiated by the terminal equipment by itself, or the terminal equipment can perform positioning according to the request of the network side. For example, the 5G gateway or the access and mobility management function AMF network element may send the location measurement request to the second network device, which in turn sends the location measurement request to the terminal device.

It should be noted that, the present application only takes the 5G gateway or the AMF network element with access and mobility management function as an example, and network elements with functions similar to those of the 5G gateway or the AMF network element with access and mobility management function in the 5G communication system or the next generation mobile communication system thereof are all included in the protection scope of the present application.

As an optional embodiment, the above wireless positioning method further includes: and the terminal equipment calculates the position of the terminal equipment according to the first measurement result and the second measurement result. That is, in case the terminal device initiates positioning by itself, the terminal device may also calculate its own position according to the first measurement result and the second measurement result.

As an optional embodiment, the above wireless positioning method further includes: the terminal equipment receives preset information sent by the first network equipment, wherein the preset information carries a first preset condition and a preset beam list.

As described above, the first preset condition and the preset beam list may be acquired by the terminal device from preset information transmitted by the first network device. Alternatively, the preset information may be system information, such as SSB. It should be understood that, in addition to the first preset condition and the preset beam list, the preset information sent by the first network device may further include other preset conditions and other beam lists, which is not limited in this embodiment of the present application. It should also be understood that the preset condition and the beam list included in the preset information sent by the first network device are preset conditions and beam lists corresponding to the first network device.

As an optional embodiment, the above wireless positioning method further includes: the terminal equipment determines a first preset condition from a plurality of preset conditions according to the current service type, wherein the plurality of preset conditions correspond to a plurality of different service types, and the first preset condition corresponds to the current service type.

It is contemplated that the system may preset multiple geofences simultaneously, or that the shape of the geofences may be varied, i.e., the above-described preset wireless boundaries may be multiple, and the preset wireless boundaries may vary. The preset conditions corresponding to different preset wireless boundaries are different, and the different preset wireless boundaries correspond to different service types, namely, the different service types correspond to different preset conditions. The terminal device may select, according to the current service type, a first preset condition corresponding to the current service type from a plurality of preset conditions. For example, if the kindergarten corresponds to the preset wireless boundary 1, the nursing home corresponds to the preset wireless boundary 2, and the industrial park corresponds to the preset wireless boundary 3, the terminal device may determine the preset condition corresponding to the nursing home as the first preset condition, that is, the preset condition corresponding to the preset wireless boundary 2 is determined as the first preset condition if the terminal device is currently in the nursing home. For example, for the scene of the nursing home, whether the old people can move out of the nursing home or not needs to be monitored in real time according to a mobile phone or a bracelet, 3 preset wireless boundaries can be set, the range of each of the preset wireless boundaries A, the preset wireless boundaries B and the preset wireless boundaries C is sequentially enlarged, the corresponding threshold value is sequentially increased (when the old people move close to the network equipment) or the corresponding threshold value is sequentially reduced (when the old people move far away from the network equipment), thus, the terminal equipment is triggered to execute primary alarming when the old people cross the preset wireless boundary A, the terminal equipment is triggered to execute secondary alarming when the old people cross the preset boundary B, the terminal equipment is triggered to execute tertiary alarming when the old people cross the preset boundary C, and the real-time monitoring of the positions of the old people is realized.

Optionally, the plurality of preset conditions may be carried in preset information sent by the first network device.

By setting different preset conditions for different service types, the wireless positioning method of the embodiment of the application can be suitable for various different scenes, for example, a plurality of preset geofences with different shapes and different ranges are set, and the positioning flexibility is improved.

For easy understanding, fig. 5 uses a terminal device as a UE, a first network device is a gNB/ng-eNB, and a second access network device is an LMF as an example, and a wireless positioning method according to an embodiment of the present application is described in detail with reference to fig. 2.

In S501, the 5GC LCS entity sends a location request to the AMF, and the AMF correspondingly receives the location request.

In S502, the AMF sends a location request to the LMF, and correspondingly, the LMF receives the location request.

In S503, the LMF sends a location measurement request to the UE, and correspondingly, the UE receives the location measurement request, and the UE is in an idle state or a deactivated state. Alternatively, the location measurement request may be specifically sent by an LPP message.

In S504, the UE measures signal quality of a serving cell, and obtains a first measurement result.

In S505, the first measurement result satisfies a first preset condition, the UE performs beam measurement, and determines a second measurement result from the beam measurement results, where the second measurement result is used to indicate the measurement result of the first beam.

In S506, the first beam is included in the preset list, and the UE performs random access and enters a connected state.

In S507, the UE sends an alert to the gNB/ng-eNB, indicating that the terminal device crosses a preset boundary, and correspondingly, the gNB/ng-eNB receives the alert.

In S508, the UE transmits the first measurement result and the second measurement result to the LMF, and the LMF receives the first measurement result and the second measurement result, respectively. Alternatively, the first measurement result and the second measurement result may be specifically transmitted through an LPP message.

In S509, the LMF determines the location of the UE according to the first measurement result and the second measurement result.

In S510, the LMF transmits location information indicating the location of the UE to the AMF, and correspondingly, the AMF receives the location information.

In S511, the AMF sends the location information to the 5GC LCS entity, and correspondingly, the 5GC LCS entity receives the location information.

For the detailed description of S504 to S507, reference is made to the method 300, and the detailed description is omitted here.

It should be understood that the steps S501 to S503 and S508 to S511 are optional steps. The AMF may send a location request to the LMF based on a location request of the 5GC LCS entity, or may send a location request to the LMF based on its own location requirements. Similarly, the LMF may send a location measurement request to the UE based on the location request of the AMF, or may send a location measurement request to the UE based on its own location requirement. The UE may measure the signal quality of the serving cell based on the location measurement request sent by the LMF, or may measure the signal quality of the serving cell based on its positioning requirement, which is not limited in the embodiment of the present application.

Fig. 6 shows a schematic flow chart of another wireless location method 600 of an embodiment of the present application. The method 600 may be applied to the communication system 100 shown in fig. 1 or the communication system 200 shown in fig. 2, and embodiments of the present application are not limited thereto. The method comprises the following steps:

s610, the terminal equipment measures the signal quality of the service cell to obtain a first measurement result, and the terminal equipment is in an idle state or a deactivated state.

S620, if the first measurement result meets the first preset condition, the terminal equipment performs beam measurement, and determines a second measurement result from the beam measurement results, wherein the second measurement result is used for indicating the measurement result of the first beam.

If the first beam is included in the preset beam list, the terminal device sends a random access request to the first network device, where the random access request carries a first preamble, and the first preamble is associated with the first beam.

The method 600 differs from the method 300 in that the method 300 informs the first network device that the terminal device crosses the preset wireless boundary by means of an explicit indication, whereas the method 600 associates the beam with the preamble for positioning and informs the first network device that the terminal device crosses the preset wireless boundary by means of an implicit indication. That is, in the method 600, when the terminal device needs to initiate an alarm, the terminal device may send a random access request by using the preamble for positioning, and the first network device may learn that the terminal device crosses the preset wireless boundary after receiving the preamble for positioning. For a detailed description of step S610 and step S620, reference may be made to step S310 and step S320 in the above-mentioned method 300, and a detailed description thereof will be omitted herein.

In this way, the terminal device only needs to send the preamble for positioning to initiate a random access request, informing the first network device that there is information that the terminal device is out of range, and the related steps of the subsequent random access may not be performed. The terminal equipment may be successfully accessed in a random manner and may be failed in a random access manner, and the embodiment of the application is not limited to the random access success and does not influence the wireless positioning method provided by the application. Therefore, according to the wireless positioning method, the terminal equipment in the idle state or the deactivated state can implicitly alarm the network equipment under the condition that the terminal equipment does not enter the random access connection state.

It should be appreciated that the first preamble in embodiments of the present application is a preamble associated with the first beam for positioning. The first network device may be capable of determining that there is a terminal device crossing a preset wireless boundary based on identifying that the first preamble is a preamble for positioning after receiving the first preamble. However, the first network device cannot determine in particular which terminal device crosses the preset radio boundary.

Optionally, in a subsequent random access procedure, the terminal device may send an Identification (ID) of the terminal device to the first network device, so that the first network device may identify that the device crossing the preset wireless boundary is the terminal device.

Alternatively, the first preamble used for positioning may be to add or subtract a part of bits from the existing preamble, or the first preamble carries a special identifier. Wherein an increased or decreased portion of bits, or a special identification, is used to indicate the first beam.

As an alternative embodiment, the location measurement request is sent to the second network device by a fifth generation mobile communication system 5G gateway or an access and mobility management function AMF network element. It should be noted that, the present application only takes the 5G gateway or the AMF network element with access and mobility management function as an example, and network elements with functions similar to those of the 5G gateway or the AMF network element with access and mobility management function in the 5G communication system or the next generation mobile communication system thereof are all included in the protection scope of the present application.

As an optional embodiment, the above wireless positioning method further includes: and the terminal equipment calculates the position of the terminal equipment according to the first measurement result and the second measurement result.

As an optional embodiment, the above wireless positioning method further includes: the terminal equipment receives preset information sent by first network equipment, wherein the preset information carries the first preset condition and the preset wave beam list.

As an alternative embodiment, the random access request is included in a contention-based random access, or the random access request is included in a two-step random access.

Reference may be made to the corresponding description in the above method 300 for other extensible embodiments of the method 600, which are not repeated here.

In S701, the 5GC LCS entity sends a location request to the AMF, and correspondingly, the AMF receives the location request.

In S702, the AMF sends a location request to the LMF, and correspondingly, the LMF receives the location request.

In S703, the LMF transmits a location measurement request to the UE, which is then correspondingly received by the UE in an idle state or a deactivated state. Alternatively, the location measurement request may be specifically sent by an LPP message.

In S704, the UE measures signal quality of the serving cell, and obtains a first measurement result.

In S705, the first measurement result satisfies a first preset condition, the UE performs beam measurement, and determines a second measurement result from the beam measurement results, where the second measurement result is used to indicate the measurement result of the first beam.

In S706, the first beam is included in the preset list, and the UE sends a random access request to the gNB/ng-eNB, the random access request carrying a first preamble, the first preamble being associated with the first beam. Correspondingly, the gNB/ng-eNB receives the random access request, and the gNB/ng-eNB can determine that the terminal equipment is about to cross the preset boundary according to the first preamble in the random access request.

In S707, the UE performs a subsequent series of random access procedures, and enters a connected state.

In S708, the UE transmits the first measurement result and the second measurement result to the LMF, and the LMF receives the first measurement result and the second measurement result, respectively. Alternatively, the first measurement result and the second measurement result may be specifically transmitted through an LPP message.

In S709, the LMF determines the location of the UE according to the first measurement result and the second measurement result.

In S710, the LMF transmits location information indicating the location of the UE to the AMF, and correspondingly, the AMF receives the location information.

In S711, the AMF sends the location information to the 5GC LCS entity, and correspondingly, the 5GC LCS entity receives the location information.

It should be understood that the steps S701 to S703 and S708 to S711 are optional steps. The AMF may send a location request to the LMF based on a location request of the 5GC LCS entity, or may send a location request to the LMF based on its own location requirements. Similarly, the LMF may send a location measurement request to the UE based on the location request of the AMF, or may send a location measurement request to the UE based on its own location requirement. The UE may measure the signal quality of the serving cell based on the location measurement request sent by the LMF, or may measure the signal quality of the serving cell based on its positioning requirement, which is not limited in the embodiment of the present application.
