Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Fig. 1 is a schematic diagram of a Location service architecture provided in this embodiment, and referring to fig. 1, a GMLC (Gateway Mobile Location center), an LMF (Location Management Function) and an LRF (Location Retrieval Function) are mainly introduced into a Location service, and functions of these 3 network functions are respectively described below.

The GMLC contains functions that need to support LCS (Location Service). In a PLMN (Public Land Mobile Network), there may be more than one GMLC. A GMLC is the first node in a PLMN that an external LCS client accesses (i.e. GMLC supported Le reference point). The AF (Application Function) and NF (Network Function) can access the GMLC directly or through the NEF (Network Exposure Function). The GMLC may request routing information and/or target UE privacy information from a UDM (Unified Data Management, Unified service based interface) over a numm interface. After performing authentication of an external LCS user and verifying target UE privacy, a GMLC forwards a location request to an AMF using a service based interface exposed by the Namf interface (Access and Mobility Management Function) or to a GMLC of another PLMN using the Ngmlc interface (service based interface exposed by the GMLC) in a roaming scenario.

The privacy content settings of the target UE should always be checked in the HPLMN of the target UE before sending the location estimate. The VGMLC is the GMLC of the serving node associated with the target UE. The HGMLC is a GMLC located at the HPLMN of the target UE, which is responsible for controlling privacy checks of the target UE.

The LRF may be co-located with the GMLC or separate and is responsible for retrieving or verifying location information.

The LMF manages the overall coordination and scheduling of resources required for the location of a UE registered to or accessing a 5G (5th generation mobile networks, fifth generation mobile communications technology) CN (Core Network). Also used to calculate or verify a final position and any velocity estimates, and also to assess the accuracy of the acquisition. The LMF receives a location request for a target UE from the serving AMF using the Nlmf interface (the service-based interface exposed by the LMF). The LMF interacts with the UE to exchange positioning information applicable to UE-assisted and UE-based positioning methods, and obtains location information with a NG-RAN (New Radio-Radio Access Network).

Fig. 1 also includes CHF (CHarging Function) and interfaces for connecting the functions, where the interfaces include N1, N2, N51, NL1, N8, N52, NL6, NL2, NL5, NL4, and N33 in addition to Le.

WLAN positioning and bluetooth positioning are described below:

for positioning methods that require the UE to provide WLAN measurement information to the network, such as UE-assisted positioning methods, the network should provide the UE with a WLAN list that includes information of the WLAN APs that the UE should measure, including BSSID (Basic Service Set) information and/or SSID (Service Set Identifier) information.

If the UE receives the WLAN list from the network, the UE should only send measurement information for WLANs for which the BSSID and/or SSID are present in the WLAN list to the network. If the UE does not receive the WLAN list from the network, the UE should only send to the network measurement information for WLANs for which the BSSID and/or SSID appear in the default WLAN list.

For positioning methods that require the UE to provide bluetooth measurement Information to the network, such as UE-assisted positioning methods, the network should provide the UE with a bluetooth list that includes Information of bluetooth APs that the UE should measure, including PUB _ ADDR _ INFO (Public _ Address _ Information) and/or DEV _ NAME _ INFO (Device _ NAME _ Information) Information.

If the UE receives a bluetooth list from the network, the UE should only send measurement information for bluetooth whose bluetooth public address and/or bluetooth device name appear in the bluetooth list to the network. If the UE does not receive a Bluetooth list from the network, the UE should only send to the network measurement information for Bluetooth with the Bluetooth public address and/or Bluetooth device name present in the default Bluetooth list.

As can be seen, if the UE does not receive the access device list, the UE may monitor the WLAN AP or the bluetooth device according to the default list. Because the default list is not updated in time according to the position change of the UE, information which cannot assist the UE in positioning exists in the information monitored by the UE, the effectiveness of the monitored information is low, and resource waste is caused. However, since it is not clear which network function in the network determines the access device list and how to send the determined access device list to the terminal at present, the UE can only monitor according to the default list.

In order to solve the problem that there is no method for how a network determines a WLAN list or a bluetooth list and how to send the WLAN list or the bluetooth list to a UE in the prior art, fig. 2 is one of the flow diagrams of the method for determining an access device list provided in this embodiment, as shown in fig. 2, the method includes the following steps:

step 201: and the first network node determines an access equipment list according to the configuration information and/or the terminal information and sends the access equipment list to the terminal.

There are various types of first network nodes that perform this step. The first network node may send the determined access device list directly to the terminal, or may send the access device list to the terminal through other network nodes. The access device list is a WLAN list or a bluetooth list.

It should be noted that, the first network node determines the access device list according to the configuration information, specifically: when the operator configures fixed equipment which is not influenced by the terminal information in the configuration information, the access equipment list is generated only according to the configuration information. The access device list includes devices fixed in the configuration information, regardless of the terminal information.

And when the terminal information changes or the configuration information of the first network node changes, the first network node determines the access equipment list. Therefore, the device or the bluetooth device corresponding to the WLAN AP in the access device list can be matched with the current location or the current configuration information of the UE, so as to provide the access device list beneficial to positioning the UE for the terminal, improve the validity of the information monitored by the UE, and avoid resource waste.

Specifically, the configuration information includes at least one of the following information: a first mapping relation between a cell identifier and equipment, a second mapping relation between a tracking area list and the equipment, a first topological relation graph determined by the distance between the equipment and a second topological relation graph determined by the signal coverage of the equipment;

the terminal information includes at least one of the following information: the method comprises the steps of identifying a cell of a cell where a terminal is located, listing a tracking area of the terminal, equipment currently connected with the terminal, and access technology and state information currently used by the terminal.

It should be noted that the configuration information is configured by the operator of the device. The device is a device corresponding to the WLAN AP or a Bluetooth device.

Specifically, the first mapping relationship includes a mapping relationship between a cell identifier and a device corresponding to the WLAN AP, and/or a mapping relationship between a cell identifier and a bluetooth device, as shown in table 1. The second mapping relationship includes a mapping relationship between the tracking area list and devices corresponding to the WLAN AP, and/or a mapping relationship between the tracking area list and the bluetooth device, as shown in table 2. The first topological relation graph comprises a topological relation graph determined by the distance between the devices corresponding to the WLAN AP and/or a topological relation graph determined by the distance between the Bluetooth devices, as shown in FIG. 3. The second topology relation graph comprises a topology relation graph determined by the signal coverage of the device corresponding to the WLAN AP and/or a topology relation graph determined by the signal coverage of the bluetooth device, as shown in fig. 4, and a circular area in fig. 4 represents the signal coverage of the device in the circular area.

Cell identity	Overlapping overlaid device information
		Cell identity 1	BSSID1, SSID1, Bluetooth device name 1, Bluetooth public address 1
Cell identity 2	BSSID2, SSID2, Bluetooth device name 2, Bluetooth public address 2

Table 2 overlapping coverage information of TAI List (Tracking Area Identity List) and WLAN AP and bluetooth devices

In the terminal information, the access technology currently used by the terminal is 3GPP (3rd Generation Partnership Project) access or non-3 GPP access, where the 3GPP access is an access technology defined by the international organization for standardization 3GPP and the non-3 GPP access is an access technology defined by other standardization organizations other than 3GPP, such as WLAN access, bluetooth access. The current state information of the terminal is in a connection state, a reachability state or an idle state.

Specifically, the access device list is a WLAN list or a bluetooth list.

Specifically, the first Network node is an access and mobility management Function AMF node, a location management Function LMF node, a gateway mobile location center GMLC node, a radio access node RAN, or a Network storage Function NRF (Network storage Function) node.

The following description is made of the first network node as the various types of network nodes described above:

for the first network node, the first network node is an AMF node

Specifically, the determining, by the first network node, an access device list according to the configuration information and the terminal information includes:

and when the first network node is the AMF node, determining an access equipment list according to the configuration information and the stored terminal information.

Specifically, the method further comprises the following steps:

and when the first network node is an AMF node, if the terminal information or the configuration information is monitored to be changed, determining an access equipment list according to the configuration information and the stored terminal information.

And when the first network node is the AMF node, sending an access equipment list to a terminal.

It should be noted that, since the AMF node can directly monitor the UE information, when the first network node is the AMF node, the access device list may be determined according to the monitored UE information and the configuration information. Or, when the first network node monitors that the configuration information changes, determining an access device list according to the changed configuration information and the currently monitored UE information.

Specifically, the sending the access device list to the terminal includes:

Specifically, when the first network node is an AMF node, the sending an access device list to a terminal includes:

and the first network node sends an access equipment list to the terminal through a non-access stratum (NAS) message.

Specifically, the NAS message is a registration accept message or a request message for updating configuration information.

It should be noted that, when the AMF node is the first network node, the first network node directly sends the determined access device list to the terminal, or sends the determined access device list to the terminal through a registration update procedure or a UE configuration update procedure, that is, sends a registration accept message or a UE configuration update request message to the UE, where the registration accept message or the UE configuration update request message includes access.

A specific example is now provided in which the first network node is an AMF node:

the application scenarios that occur in this specific example are: the AMF node discovers that it needs to update the WLAN list or bluetooth list of the UE (e.g. due to UE movement, or a change in network configuration).

Firstly, when the AMF node monitors that the UE information changes or the configuration information changes, the process of determining an access equipment list is triggered;

the process of determining the access device list by the AMF node can be implemented by the following several ways:

1) the AMF node determines from the cell identifier (e.g., cell identifier 2) of the UE camped on the cell through the first mapping relation of the configuration information table 1, and the WLAN list includes BSSID2 and SSID 2. Or, the bluetooth list includes the bluetooth device name 2 and the bluetooth public address 2, determined by the first mapping relationship in the configuration information table 1.

2) The AMF node determines from the tracking area list (e.g., tracking area list 2) of the UE, which includes BSSID2, SSID2, BSSID4, SSID4, through the second mapping relationship of the above configuration information table 2. Or, the bluetooth list includes the bluetooth device name 2 and the bluetooth public address 2, determined by the second mapping relationship of the configuration information table 2.

3) When the operator configures the device topology as shown in fig. 3 in the AMF node. The AMF node determines the WLAN list including device 1, device 4 and device 5 according to the SSID of the WLAN AP to which the UE is currently connected (assuming that the SSID is the SSID of device 2 in fig. 3) and according to the device topology relationship diagram shown in fig. 3. Or, the AMF node determines a bluetooth list including the device 1, the device 4, and the device 5 according to the identifier of the bluetooth device currently connected to the UE (assuming that the identifier of the bluetooth device is the identifier of the device 2 in fig. 3) and according to the device topology relationship diagram shown in fig. 3.

4) When the operator configures the device topology as shown in fig. 4 in the AMF node. The AMF node determines the WLAN list including device 1, device 2 and device 4 according to the SSID of the WLAN AP to which the UE is currently connected (assuming that the SSID is the SSID of device 3 in fig. 4) and according to the device topology relationship diagram shown in fig. 4. Or, the AMF node determines a bluetooth list including the device 1, the device 4, and the device 5 according to the identifier of the bluetooth device currently connected to the UE (assuming that the identifier of the bluetooth device is the identifier of the device 3 in fig. 4) and according to the device topology relationship diagram shown in fig. 4.

Then, after determining the access device list, the AMF node directly transmits the determined WLAN list or bluetooth list to the UE. Specifically, the AMF node may send the WLAN list or the bluetooth list to the UE during a periodic location update procedure or during a UE configuration update procedure. For example, the AMF node includes a WLAN list or a bluetooth list in an existing registration accept message or a UE configuration update request message, so that the UE saves and uses the WLAN list or the bluetooth list.

(II) as LMF node for the first network node

Specifically, the determining, by the first network node, an access device list according to the configuration information and the terminal information includes: and when the first network node is the LMF node, determining an access equipment list according to the configuration information and the terminal information stored or sent by the second network node.

Specifically, the method further comprises the following steps:

when the first network node is an LMF node, if the configuration information is monitored to be changed, an access equipment list is generated according to the configuration information and the stored terminal information, or if the terminal information sent by the second network node is received, the access equipment list is determined according to the configuration information and the terminal information sent by the second network node.

Specifically, the sending the access device list to the terminal includes: and when the first network node is the LMF node, sending an access equipment list to the terminal through a third network node, wherein the third network node is the AMF node.

Specifically, when the first network node is an LMF node, sending an access device list to a terminal through a third network node includes:

when the first network node is an LMF node, sending a positioning request message or an event report confirmation message to a third network node so that the third network node sends the received positioning request message or the event report confirmation message to a terminal;

the positioning request message or the confirmation message of the event report carries the access device list.

In addition, another way of determining the access device list for the LMF node by the first network node is provided: the LMF determines to use WLAN positioning according to the access technology and the state in the access technology, and then the LMF determines a WLAN list according to the cell identification or the tracking area list and the local configuration information. Alternatively, the LMF determines the WLAN list based on the access technology, the state within the access technology, the cell identity or tracking area list, and the local configuration information.

A specific example is now provided in which the first network node is an LMF node:

the application scenarios that occur in this specific example are: when the AMF node monitors that the UE information changes, for example, due to the triggering of UE movement or network configuration change, the AMF node sends new UE information to the LMF node. Or, the UE sends an event report to the AMF node, and the AMF node sends the event report and the UE information to the LMF node.

After receiving the UE information provided by the AMF node, the LMF node triggers the process of determining the access equipment list;

the process of the LMF node determining the access device list may be implemented in several ways:

1) the LMF node determines, according to the cell identifier (e.g., cell identifier 1) of the cell where the UE resides in the UE information, through the first mapping relationship in the configuration information table 1, that the WLAN list includes BSSID1 and SSID 1. Or, the bluetooth list includes the bluetooth device name 1 and the bluetooth public address 1, determined by the first mapping relationship in the configuration information table 1.

2) The LMF node determines from the UE's tracking area list (e.g., tracking area list 1) through the second mapping relationship of the above configuration information table 1, the WLAN list including BSSID1, SSID1, BSSID3, SSID 3. Or, the bluetooth list includes the bluetooth device name 1 and the bluetooth public address 1, determined by the second mapping relationship of the configuration information table 2.

3) When the operator configures the device topology as shown in figure 3 in the LMF node. The LMF node determines the WLAN list including the device 1, the device 4 and the device 5 according to the SSID of the WLAN AP to which the UE is currently connected (assuming that the SSID is the SSID of the device 2 in fig. 3) and according to the device topology relationship diagram shown in fig. 3. Or, the LMF node determines the bluetooth list including the device 1, the device 4, and the device 5 according to the identifier of the bluetooth device currently connected to the UE (assuming that the identifier of the bluetooth device is the identifier of the device 2 in fig. 3) and according to the device topology relationship diagram shown in fig. 3.

4) When the operator configures the device topology as shown in figure 4 in the LMF node. The LMF node determines the WLAN list including the device 1, the device 2, and the device 4 according to the SSID of the WLAN AP to which the UE is currently connected (assuming that the SSID is the SSID of the device 3 in fig. 4) and according to the device topology relationship diagram shown in fig. 4. Or, the LMF node determines the bluetooth list including the device 1, the device 4, and the device 5 according to the identifier of the bluetooth device currently connected to the UE (assuming that the identifier of the bluetooth device is the identifier of the device 3 in fig. 4) and according to the device topology relationship diagram shown in fig. 4.

Then, after determining the access device list, the LMF node sends the determined WLAN list or bluetooth list to the AMF node, and sends the WLAN list or bluetooth list to the UE through the AMF node. Specifically, the LMF node determines a new WLAN list or bluetooth list and then returns to the AMF node. And the AMF node sends a new WLAN list or a new Bluetooth list to the UE in a periodic registration process or a UE configuration updating process, or the LMF node determines the WLAN list or the Bluetooth list according to the information of the UE and then returns a confirmation message of receiving the event report to the UE, wherein the confirmation message comprises the new WLAN list or the Bluetooth list, and the confirmation message of the event report is transmitted to the UE through the AMF node.

Fig. 5 is a schematic diagram of a process of determining an access device list by an LMF node to achieve UE positioning according to this embodiment, and referring to fig. 5, the process includes:

1. the AMF node sends a Nlmf _ Location _ DetermineLocation request (positioning request) to the LMF node, and the message comprises UE information.

2. The LMF determines a WLAN AP list or a Bluetooth list according to the UE information and the configuration information, and sends a Namf _ Communication _ N1N2MessageTransfer (a downlink positioning message (carrying the WLAN list or the Bluetooth list)) to the AMF node.

3. The AMF node sends a downlink NAS transport message (downlink positioning message) to the UE.

4. And the UE judges the WLAN AP or Bluetooth appearing in the list around according to the WLAN list or Bluetooth list in the downlink positioning message, and monitors the information of the WLAN AP or Bluetooth.

5. And the UE sends an uplink NAS transmission message (uplink positioning message) to the AMF node, wherein the uplink positioning message comprises information of WLAN AP or Bluetooth monitored by the UE.

6. The AMF node sends a Namf _ Communication _ N1MessageNotify (uplink positioning message) to the LMF node.

7. The LMF node calculates the UE position according to the measurement information in the uplink positioning message, and then sends a Nlmf _ Location _ DetermineLocation reply message to the AMF node, wherein the message comprises the UE position information.

(III) for the first network node as a GMLC node

Specifically, the determining, by the first network node, an access device list according to the configuration information and the terminal information includes: and when the first network node is the GMLC node, determining an access equipment list according to the configuration information and the terminal information stored or sent by the second network node.

In this embodiment, the second network node is an AMF node or a UDM node.

Specifically, the method further comprises the following steps:

when the first network node is a GMLC node, if the configuration information is monitored to change, an access equipment list is generated according to the configuration information and the stored terminal information, or if the terminal information sent by the second network node is received, the access equipment list is determined according to the configuration information and the terminal information sent by the second network node.

Specifically, the sending the access device list to the terminal includes: and when the first network node is the GMLC node, sending an access equipment list to the terminal through a third network node, wherein the third network node is an AMF node.

Specifically, when the first network node is a GMLC node, the sending, by a third network node, an access device list to a terminal includes:

when the first network node is a GMLC node, sending a positioning request message or an event report confirmation message to a third network node so that the third network node sends the received positioning request message or the event report confirmation message to a terminal;

In addition, another way of determining the access device list for the GMLC node by the first network node is provided: and the GMLC determines that the UE is in a connection state in the WLAN access according to the access technology and the state in the access technology, and then determines a WLAN list according to the cell identifier or the tracking area list and the local configuration information. Alternatively, the GMLC decides the WLAN list based on the access technology, the state within the access technology, the cell identity and tracking area list and local configuration information.

A specific example is now provided in which the first network node is a GMLC node:

to summarize, when the GMLC node decides to change the WLAN list or the bluetooth list (the triggering condition may be that the AMF node provides new UE information, the UDM node provides new information of the UE or a local configuration change, etc.), the GMLC node sends the new list to the AMF node, the AMF node sends the new list to the LMF node, and the LMF node sends the new list to the UE.

The method specifically comprises the following conditions:

case 1: when the AMF node monitors that the UE information changes, for example, due to the triggering of UE movement or network configuration change, the AMF node sends new UE information to the GMLC node, and the GMLC node determines a new WLAN list or Bluetooth list and then returns the new WLAN list or Bluetooth list to the AMF node. And the AMF node sends a new WLAN list or a new Bluetooth list to the UE through a periodic registration process or a UE configuration updating process.

Case 2: when the UDM node monitors that the UE information changes, for example, the UE moves, the AMF node changes, or the connection state of the UE in the access network changes, the UDM node sends new UE information to the GMLC node, and the GMLC node determines a new WLAN list or bluetooth list and then sends the new WLAN list or bluetooth list to the AMF node. And the AMF node sends a new WLAN list or a new Bluetooth list to the UE through a periodic registration process or a UE configuration updating process.

Case 3: the configuration information in the GMLC node is changed, the GMLC node updates a WLAN list or a Bluetooth list, the GMLC node sends the new list to the AMF node, and the AMF node sends the new WLAN list or the Bluetooth list to the UE in a periodic registration process or a UE configuration updating process.

The process of determining the access device list is the same as the process of determining the first network node as the AMF node or the LMF node, and is not described herein again.

The configuration information in the RAN is shown in table 1. For example, when the UE broadcasts a WLAN list including BSSID1 and SSID1 in the cell identified as cell identity 1, the broadcast bluetooth list includes bluetooth device name 1 and bluetooth public address 1. The RAN broadcasts a list of WLANs including BSSID2, SSID2, and a list of bluetooth broadcasts including bluetooth device name 2, bluetooth public address 2, within the cell identified as cell identification 2.

An embodiment is now provided for determining a list of access devices based on terminal information:

specifically, the determining, by the first network node, an access device list according to the terminal information, and sending the access device list to the terminal includes:

when the first network node is an NRF node, if terminal information sent by a fourth network node is received, returning an access equipment list to the fourth network node so as to send the access equipment list to a terminal through the fourth network node;

and the fourth network node is an AMF node, an LMF node or a GMLC node.

Specifically, the fourth network node sends UE information (e.g., a tracking area list of the cell or UE where the UE is located) to the NRF, and the NRF returns an access device list to the fourth network node. The fourth network node is an AMF node, an LMF node or a GMLC node.

Specifically, when the fourth network node is an AMF node, the fourth network node sends the received access device list to the terminal; and when the fourth network node is the LMF node or the GMLC node, the fourth network node sends the access equipment list to the AMF node, and the AMF node sends the received access equipment list to the terminal.

The above-mentioned process of the first network node determining the access device list and sending the access device list to the terminal is generally applicable to the following application scenarios: the UE needs to send location information or location monitoring information to the network periodically or triggered by certain conditions, if the UE needs to report the location due to the timeout of the location reporting period or the triggering condition of the location reporting (e.g., the UE moves out of a specific area) after the UE moves, there may not be a valid WLAN list or bluetooth list in the UE (e.g., there is no WLAN or bluetooth present in the list around the current location of the UE), and the UE needs to monitor the WLAN or bluetooth information using a default WLAN list or bluetooth list.

In the method for determining the access device list provided by this embodiment, the determination of the access device list is realized through the AMF node, the GMLC node, the LMF node, or the RAN, and the access device list is sent to the terminal, so that the terminal monitors the devices in the access device list, obtains information favorable for positioning the terminal, improves the effectiveness of the monitored information, and avoids resource waste.

In addition, fig. 6 is a second flowchart illustrating a method for determining an access device list, as shown in fig. 6, the method for determining an access device list includes:

step 601: and if the second network node monitors that the terminal information changes, the monitored terminal information is sent to the first network node, so that the first network node determines an access equipment list according to the configuration information and the terminal information sent by the second network node.

And the second network node sends the terminal information to the first network node and triggers the process that the first network node determines the access equipment list. The determination of the access device list is achieved by this procedure.

The second network node may be an AMF node or a UDM node. Typically, when the second network node is an AMF node, the first network node is an LMF node or a GMLC node; when the second network node is a UDM node, the first network node is a GMLC node.

Specifically, if the second network node monitors that the terminal information changes, the monitored terminal information is sent to the first network node;

when the second network node is an AMF node, if the terminal information is monitored to be changed, the monitored terminal information is sent to a first network node, wherein the first network node is an LMF node or a GMLC node;

and when the second network node is a UDM node, if the terminal information is monitored to be changed, sending the monitored terminal information to a first network node, wherein the first network node is a GMLC node.

And sending the terminal information to the first network node through the second network node, and triggering the first network node to determine a new access equipment list, so that the access equipment list in the UE is updated in time, and the UE is ensured to obtain information beneficial to positioning the UE in the process of monitoring the equipment.

In addition, fig. 7 is a third flowchart illustrating a method for determining an access device list, as shown in fig. 7, the method for determining an access device list includes:

step 701: receiving an access equipment list sent by a first network node or a third network node, and monitoring equipment in the access equipment list;

The method for determining the access device list is executed by the terminal. After receiving the access device list, the UE monitors information of the devices in the access device list, for example, monitors information of the devices, such as signal strength and round trip delay. And then the UE sends the monitored information to a network node needing to determine the position of the UE, so that the network node determines the position of the UE according to the information monitored by the UE.

The UE receives the access equipment list to realize the real-time update of the access equipment list stored in the UE, so that the UE can provide effective monitoring information in the UE-assisted positioning method, thereby realizing the accurate positioning of the UE.
