The terminal may also be referred to as a terminal Device or a User Equipment (UE), where the terminal may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or a vehicle-mounted Device, and a specific type of the terminal is not limited in the embodiment of the present invention.

The network device may be a base station or a core network element. The Base Station may be a 5G or later-version Base Station (e.g., a gNB, a 5G NR NB, etc.), or a Base Station in other communication systems (e.g., an eNB, a WLAN access point, or other access points, etc.), and may be referred to as a node B, an evolved node B, an access point, a Base Transceiver Station (BTS), a radio Base Station, a radio Transceiver, a Basic Service Set (BSS), an Extended Service Set (ESS), a node B, an evolved node B (eNB), a home node B, a home evolved node B, a WLAN access point, a WiFi node, or some other suitable term in the field, which is not limited to a specific technical vocabulary as long as the same technical effect is achieved.

The core network element may be an Access and Mobility Management Function (AMF), which may also be referred to as an Access Management Function; and optionally a Session Management Function (SMF).

In the embodiment of the present invention, the base station may be combined with a Location Management Function (LMF) (i.e., combined) or may be separately arranged from the LMF (i.e., split). In the case of a base station and an LMF combined, the base station may implement the functionality of the LMF. And under the condition that the base station and the LMF are separately arranged, the base station and the LMF respectively realize the functions of the base station and the LMF.

In the embodiment of the invention, a Location Services (LCS) center deploys an LMF at a base station side, the LMF manages an LCS area (area), the LMF can broadcast an LCS area index through a base station, the LMF can obtain an AS key of a terminal user through the base station in the process of terminal Registration (Registration) or Service Request (Service Request), and the terminal obtains an LCS area index list capable of providing the LCS in the process.

Optionally, when the terminal is in an RRC-Inactive state, the terminal may initiate a LCS-specific RRC recovery (Resume) procedure (that is, carrying a LCS MO-LR Invoke) to the base station broadcasting the LCS area index by using the AS-derived key, so AS to activate a LCS-specific DRB (the base station may obtain the AS-derived key through a Location determination Response (Location determination Response) message sent by the LMF), and interact an LPP procedure with the LMF through a user Plane U-Plane; and the broadcasted LCS area index is in the list of LCS area indices obtained during registration or service request.

Wherein, the base station fast positioning capability information may be selected as at least one of the following: the base station includes indication information indicating that the base station supports fast positioning, an area information list (such as a tracking area TA list or a cell information list, where the cell information is, for example, a cell frequency point, a cell identifier (cell id), etc.) supporting fast positioning, and an area information index list supporting fast positioning.

In one embodiment, after receiving the fast positioning capability information of the terminal and/or the base station, the AMF may forward it to the SMF, for example, including the capability information in a parameter of an update context Request (Nsmf _ duration _ update smcontext Request) for invoking the SMF.

In one embodiment, the base station may also send the base station fast positioning capability information to the AMF when establishing a connection with the AMF, i.e., the base station positioning capability information may be transmitted to the AMF in a process independent of the end user process.

In another embodiment, the AMF or SMF may further acquire the fast positioning capability information of each base station through interaction with the management platform.

Step 803: the AMF or SMF sends a subscription data Request message, such as a numm _ SDM _ Get Request message, for invoking a subscription service to the UDM.

Optionally, if the AMF or the SMF receives the terminal fast positioning capability information, the terminal fast positioning capability information may be included in the subscription data request message.

Step 804: the UDM returns a subscription data Response message, such as a Nudm _ SDM _ Get Response message, to the AMF or SMF.

Optionally, the subscription data response message includes subscription data, such as location service information. The location service information may include at least one of: indication information indicating that the end user is allowed to use the location service, and area information (such as a TA list, or a cell id list) indicating that the end user is allowed to use the location service.

In one embodiment, the UDM may determine whether to return location service information according to whether to receive the terminal fast positioning capability information; for example, the returned location service information is determined according to the received terminal quick positioning capability information.

Step 805: after receiving the subscription data, the AMF sends a response message (e.g., NAS message) to the base station. Optionally, the response message may be a Registration acceptance NAS message, such as a NAS Registration Accept message; or a Service acceptance NAS message, such as a NAS Service Accept message.

In one embodiment, if the SMF receives the subscription data, the SMF may first return an update context Response (e.g., Nsmf _ pdusesion _ update smcontext Response) message to the AMF, or call the AMF's Namf _ Communication _ N1N2message transfer Request; then, the AMF transmits a service acceptance NAS message to the base station.

Optionally, if the subscription data received by the AMF includes location service information, the AMF may send a message including the location service information, such as an N2 Request message, to the base station; the Registration Accept NAS message may be merged with the N2 Request message and sent, that is, the N2 Request message carries the NAS Registration Accept message.

Alternatively, if the SMF receives subscription data including location service Information, the SMF may send the location service Information to the AMF, for example, return an Nsmf _ pdusesion _ update smcontext Response message including an N2 SM Information parameter to the AMF, or include an N2 SM Information parameter in a naff _ Communication _ N1N2MessageTransfer Request message that invokes the AMF, where the N2 SM Information parameter includes location service Information. After receiving the location service information, the AMF includes the location service information in a message, such as an N2 Request message, sent to the base station.

In one embodiment, the AMF or SMF may further include fast positioning configuration information in a message sent by the AMF or SMF; the fast positioning configuration information may include: an area information list supporting fast positioning and/or an area information index list supporting fast positioning.

In one embodiment, the AMF or SMF may further search for areas supporting fast positioning existing in a Routing Area (Routing Area, i.e. a group of Tracking areas, where a terminal needs to send a registration message when moving from one Routing Area to another Routing Area) where the terminal is located, and reflect the searched areas in an Area information list and/or an Area information index list carried in a NAS message sent to the terminal.

In one embodiment, the AMF may also include a location service key in a message sent to the base station, such as the N2 Request message. And the N2 Request message may comprise the NAS message described above.

Step 806: the base station or LMF stores location service information.

Optionally, if the base station is combined with the LMF, the base station stores the location service information; and if the base station and the LMF are separately arranged, the base station sends the location service information to the LMF, and the LMF stores the location service information.

Step 807: the base station forwards the NAS message received in step 205 to the terminal.

Application scenario 2

Application scenario 2 of the embodiment of the present invention mainly describes a location service configuration process. Referring to fig. 9, the corresponding configuration process includes the following steps:

step 901: the LMF sends a subscription Request message to the AMF or the SMF, for example, sends a Location User subscription Request message.

Optionally, the request message may include base station fast positioning capability information, where the base station fast positioning capability information may include at least one of the following: the base station includes indication information indicating that the base station supports fast positioning, an area information list (such as a TA list or a cell information list, where the cell information is, for example, a cell frequency point, a cell identifier (cell id), etc.) supporting fast positioning, and an area information index list supporting fast positioning.

In one embodiment, the AMF or the SMF may further acquire the fast positioning capability information of the base station of each LMF through interaction with the management platform.

Step 902: and the AMF or the SMF sends a subscription Response message to the LMF, such as a Location User subscription Response message.

And (4) optional. The subscription response message can include an area information index list supporting quick positioning; the indices in the index list correspond to certain area information or certain area information that support fast positioning.

Step 903: the terminal sends a request message to the base station. Optionally, the Request message may be a Registration Request message, such as a NAS Registration Request message; or a Service Request message such as a Service Request message. The request message may include terminal fast positioning capability information, such as indication information indicating that the terminal supports fast positioning, or quality of service (QoS) information of the location service, etc.

Step 904: the base station does not process the received request message (e.g., NAS message) and forwards it to an Access Management Function (AMF). Optionally, if the request message is a service request message, the AMF further sends the request message to a Session Management Function (SMF).

In one embodiment, after receiving the fast positioning capability information of the terminal, the AMF may forward it to the SMF, for example, by including the capability information in a parameter of an update context Request (Nsmf _ pudssesion _ update smcontext Request) for invoking the SMF.

Step 905: the AMF or SMF sends a subscription data Request message, such as a numm _ SDM _ Get Request message, for invoking a subscription service to the UDM.

Step 906: the UDM returns a subscription data Response message, such as a Nudm _ SDM _ Get Response message, to the AMF or SMF.

Step 907: after receiving the subscription data, the AMF sends a response message (e.g., NAS message) to the base station. Optionally, the response message may be a Registration acceptance NAS message, such as a NAS Registration Accept message; or a Service acceptance NAS message, such as a NAS Service Accept message.

Optionally, if the SMF receives subscription data including location service Information, the SMF may send the location service Information to the AMF, for example, return an Nsmf _ pdusesion _ update smcontext Response message including an N2 SM Information parameter to the AMF, or include an N2 SM Information parameter in a naff _ Communication _ N1N2MessageTransfer Request message that invokes the AMF, where the N2 SM Information parameter includes location service Information. After receiving the location service information, the AMF includes the location service information in a message, such as an N2 Request message, sent to the base station.

In one embodiment, the AMF may further include an area information list supporting fast positioning and/or an area information index list supporting fast positioning in the registration accept message. Alternatively, the SMF may further include an area information list supporting fast positioning and/or an area information index list supporting fast positioning in the service acceptance message through the AMF. For example, first, the SMF returns an Nsmf _ pdussion _ update smcontext Response message including an N1 SM Information parameter to the AMF, or includes an N1 SM Information parameter in a Namf _ Communication _ N1N2MessageTransfer Request message that calls the AMF; then, the AMF sends a service acceptance message including an N1 SM Information parameter to the base station, where the N1 SM Information parameter includes an area Information list supporting fast positioning and/or an area Information index list supporting fast positioning.

Step 908: if the subscription data contains the Location service information, the AMF or the SMF sends a Location User notification message including the Location service information, such as a Location User Notify message, to the LMF.

Wherein, the notification message may include a location service key. The location service key may be generated by a user key and some parameters that the terminal may also know, and thus the terminal may also generate the same location service key.

Step 909: the LMF stores location service information.

Optionally, the LMF may also store a location service key.

Step 910: the base station forwards the message received in step 907 to the terminal.

Step 911: the AMF learns that the routing area of the end user changes. For example, the AMF receives a registration message sent by the terminal from a new routing area, or receives other AMFs requesting transfer of context data of the terminal user.

Step 912: optionally, the AMF sends a location user subscription notification message to the LMF to instruct the LMF to delete the relevant information of the end user, or instruct the LMF to update the reference value of the relevant information of the end user. The LMF may periodically delete the end-user related information with a reference value of 0.

It should be noted that the above steps 901 to 912 are location service configuration procedures in the case of base station and LMF allocation. If the base station and the LMF are jointly configured, the operation performed by the LMF is changed to the operation performed by the base station, that is, the message sent by the LMF in the step 901 is changed to the message sent by the base station, and the message sent to the LMF in the steps 302, 308, and 312 is changed to the message sent to the base station.

Application scenario 3

Application scenario 3 of the embodiment of the present invention mainly describes a location information acquisition process in a case where a base station and an LMF are separately located. Referring to fig. 10, the corresponding acquiring process includes the following steps:

step 1001: optionally, the terminal is in an Inactive state (Inactive), that is, the connection between the terminal and the mobile network has no wireless air interface part, and the core network part still exists. The terminal in the inactive state can recover the whole connection with the mobile network only by recovering the connection of the wireless air interface part.

Step 1002: optionally, the base station may send a broadcast message including the base station fast positioning capability Information over a wireless air interface, for example, via a System Information (System Information) message. The base station fast positioning capability information may include at least one of: the base station comprises indication information for indicating that the base station supports fast positioning, an area information list for supporting fast positioning and an area information index list for supporting fast positioning. The base station may also send the base station fast positioning capability information to the terminal through an RRC message, for example, send an RRC Connection configuration (RRC Connection Reconfiguration) message including the base station fast positioning capability information to the terminal in a Service Request (Service Request) procedure.

Step 1003: optionally, when the terminal is in an Idle state (Idle), the terminal establishes a connection with the mobile network through interaction with the base station and the AMF.

Step 1004: the terminal transmits a location service request message to the base station. Alternatively, the location service Request message may be an RRC recovery Request (RRC Resume Request) message, an RRC Uplink Direct Transfer (RRC Uplink Direct Transfer) message, or an RRC Connection Request (RRC Connection Request) message. The base station may process RRC messages.

In one embodiment, before sending the location service request message, the terminal may determine whether the base station fast positioning capability information is received, and determine whether to initiate a location service request. For example, if the base station fast positioning capability information is received, a location service request is initiated; or if the TA, the cell or the cell frequency point where the terminal is located is in the area included by the base station quick positioning capability information, initiating a position service request; or, if the TA, the cell or the cell frequency point where the terminal is located is in the area indicated by the area information index supporting the fast positioning included in the fast positioning capability information of the base station, initiating a location service request.

In one embodiment, the location service request message may be protected based on a location service key. For example, the terminal may use the location service key or a derivative key of the location service key (e.g., calculate a derivative key through an HMAC-SHA-256 function using the location service key and other parameters, or generate the derivative key in a nested manner, for example, calculate a new key one through the HMAC-SHA-256 function using the location service key and other parameters one, calculate a new key two through the HMAC-SHA-256 function using the new key one and other parameters two, and so on, finally obtain the derivative key) to generate a check code or encrypt all or part of the content of the request message, for example, calculate a message check code MAC using an AES integrity protection algorithm using the derivative key and part or all of the content in the message, and carry the message.

Step 1005: the base station selects an LMF serving the terminal, and the base station sends a Location determination Request message, such as a Location determination Request message, to the LMF.

In one embodiment, the base station may allocate an IP address to the terminal, and may also allocate a downlink tunnel identifier to the terminal. The location determination request message may include the IP address and may further include the downlink tunnel identifier.

Optionally, the base station may request the LMF for the location service key of the end user to process the message in step 1004 (e.g., check the MAC, reject the location service request if the check fails, or decrypt the encrypted portion of the message). Alternatively, the base station may send the message in step 1004 to the LMF to request the LMF to process (check or decrypt) and return the processed information.

Optionally, the LMF may determine whether to accept the location service request of the terminal based on the location service information of the terminal user. For example, the LMF may determine whether the location of the terminal is in a location where the terminal is allowed to use the location service in the location service information, or determine whether the location service information allows the terminal user to use the location service; if the judgment result is negative, the LMF does not accept the position service request of the terminal and sends a service refusing response message to the base station, otherwise, the LMF sends a user plane establishment request message to the base station.

In addition, the LMF may also check the received MAC, and send a denial of service response message to the base station if the check fails. For example, the denial of service response Message may be a Location Message Transfer (Location Message Transfer) Message including a Cause value, or an LCS-MOLR Reject Message. In one embodiment, when the base station informs the terminal that the location service is rejected, it may send an RRC recovery Reject (RRC Resume Reject) message or an RRC Release (RRC Release) message; the RRC recovery Reject or RRC release message may include a LCS-MOLR Reject message.

Step 1006: when LMF provides position service to terminal, if User surface transmission is selected, then User surface establishing Request message is sent to base station, such as Location User Plane Establishment Request message.

In one embodiment, the LMF may allocate an IP address to the terminal and may also allocate an uplink tunnel identifier to the terminal. The user plane establishment request message may include the IP address and may further include the downlink tunnel identifier. The user plane establishment request message may further include a location service key or a key derived based on the location service key.

Step 1007: the base station sends a bearer establishment request message to the terminal.

Optionally, the bearer establishment request message may be an RRC recovery message or an RRC connection configuration message. The bearer establishment request message may include an IP address of the terminal, which may be assigned by the base station or received from the LMF. The bearer establishment request message may be encrypted or secured using a location service key or a derivative key based on the location service key.

Step 1008: the terminal sends a bearer establishment response message to the base station.

Optionally, the bearer setup response message may be an RRC recovery Complete (RRC Resume Complete) message or an RRC Connection configuration Complete (RRC Connection Reconfiguration Complete) message. The bearer establishment response message may be encrypted or secured using the location service key or a derivative key based on the location service key.

Step 1009: the base station sends a User Plane Establishment completion Response message to the LMF, for example, sends a Location User Plane Establishment Response message to complete the User Plane Establishment through the LMF.

Step 1010: the LMF sends location assistance information to the base station.

Optionally, the LMF may send an IP message or signaling including an LPP message to the base station, where the LPP message includes the location assistance information, and the IP message or the LPP message may be encrypted or completely protected by using a location service key or a derivative key based on the location service key.

In one embodiment, if user plane transmission is used, the LMF may send the LPP message using an IP message through a tunnel with the base station, or send the IP message including the LPP message using a downlink tunnel identifier. Alternatively, if the transmission is performed using the control plane (i.e., the user plane is not used), the LMF may send a Location Message Transfer Request (Location Message Transfer Request) Message to the base station, where the Request Message includes an LPP Message, and the LPP Message includes Location assistance information.

Step 1011: if the control plane transmission is used, the base station may forward the location assistance information to the terminal through an RRC signaling message. Alternatively, if user plane transmission is used, the base station may send an IP packet including an LPP message to the terminal.

Optionally, the RRC signaling message may be an RRC Early Data (RRC Early Data) message, an RRC recovery (RRC Resume) message, or an RRC Downlink Direct Transfer (RRC Downlink Direct Transfer) message. The RRC signaling message may include an LPP message including location assistance information. The base station may encrypt or secure the transmitted message or data using the location service key or a derivative of the location service key.

Step 1012: the terminal returns location decision information to the base station, for example, the location decision information is carried by LPP message.

In one embodiment, if the terminal has the capability, the calculated position information may be used as the position decision information. If the control plane transmission is used, the terminal may send an RRC signaling message including an LPP message, such as an RRC Early Data message, an RRC Uplink Direct Transfer message, or an RRC response Complete message, to the base station. Alternatively, if user plane transmission is used, the terminal may send an IP packet including an LPP message to the base station. The terminal may encrypt or secure the transmitted message or data using the location service key or a derivative of the location service key.

In one embodiment, if the terminal has the capability to calculate or obtain location information, the location information may be sent to the location application server via a connection with the location application server (i.e., via the user plane of the mobile network).

Step 1013: and the base station forwards the position decision information from the terminal to the LMF.

Optionally, if the user plane transmission is used, the base station may forward the received IP packet through a tunnel with the LMF, or forward the IP packet including the LPP message using the uplink tunnel identifier. Alternatively, if the control plane transmission is used, the base station may send a signaling Message including the received LPP Message, such as a Location Message Transfer Response (Location Message Transfer Response) Message, to the LMF.

Alternatively, the steps 1010 to 1013 may be performed multiple times as required, so as to continuously exchange the information of the calculated position, so as to finally obtain the position information with the required precision.

Step 1014: if the terminal has no ability to calculate the position information, the LMF can calculate the position information by utilizing the interactive information.

Step 1015: the LMF sends a Location decision Response message, such as a Location determination Response message, to the base station. Wherein, the response message may include the location information.

Step 1016: the base station returns a location service response message, namely, a result of the location service request, to the terminal.

Optionally, the location service response message may include location information, such as location information calculated for the LMF. The location service response message may be an RRC response message or an RRC Downlink Direct Transfer message. The location service response message may include an LCS-MOLR Return Result message including location information.

In one embodiment, after the terminal obtains the location information, the location information may be sent to the location application server through a connection with the location application server (i.e., through a user plane of the mobile network).

Step 1017: optionally, the base station sends a Location Update Request message, such as an Update Location Request message, to the AMF. The obtained location information may be included in the request message.

Step 1018: the AMF sends a Location Update notification message, such as a call Update Location notification message, to a Location center (GMLC), where the notification message includes the obtained Location information.

step 1101 to step 1104: the same as the above steps 1001 to 1004.

Step 1105: the base station sends a bearer establishment request message to the terminal.

Optionally, the bearer establishment request message may be an RRC recovery message or an RRC connection configuration message. The bearer establishment request message may include an IP address of the terminal, which may be assigned by the base station. The bearer establishment request message may be encrypted or secured using a location service key or a derivative key based on the location service key.

In one embodiment, the base station may allocate an IP address to the terminal, and may also allocate a downlink tunnel identifier to the terminal.

Optionally, after receiving the location service request message, the base station may determine whether to accept the location service request of the terminal based on the location service information of the terminal user. For example, the base station may determine whether the location of the terminal is in a location where the terminal is allowed to use the location service in the location service information, or determine whether the terminal user is allowed to use the location service in the location service information; if not, the base station does not accept the position service request of the terminal and sends a service refusing response message to the terminal, otherwise, the base station sends a bearing establishment request message to the terminal.

Step 1106: the terminal sends a bearer establishment response message to the base station.

Step 1107: the base station transmits the location assistance information to the terminal.

Optionally, if the control plane transmission is used, the base station may send the location assistance information to the terminal through an RRC signaling message. Alternatively, if user plane transmission is used, the base station may send an IP packet including an LPP message including location assistance information to the terminal.

Step 1108: the terminal returns location decision information to the base station, for example, the location decision information is carried by LPP message.
