Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.

In the embodiment of the present application, "and/or" describes an association relationship of an association object, which indicates that three relationships may exist, for example, a and/or B, and may indicate: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

The 3GPP LMF positioning architecture is shown in fig. 1, where:

the positioning server LMF is responsible for selecting a positioning method and triggering corresponding positioning measurement, and can calculate a final positioning result and accuracy;

an NG-RAN (Next Generation Radio Access Network, 5G Radio Access Network) node can send a positioning reference signal or perform positioning measurement based on auxiliary information;

a UE (User Equipment, User terminal) may send a positioning reference signal, or perform positioning measurement based on auxiliary information; positioning end results and accuracy may also be calculated based on the measurements.

The LPP protocol is a point-to-point protocol located between the LMF and the target device, and the protocol is applicable to LTE and also can be used in positioning of an NR (New Radio, New wireless) communication system, where a protocol stack in NR is shown in fig. 2. As shown in fig. 2, at the UE side, the LPP message is encapsulated in a NAS (Non-Access Stratum) message, and then is encapsulated in a rrc (radio Resource control) message and transmitted to the RAN-side node.

As shown in fig. 3, a process of obtaining location information by the LMF mainly includes:

1) registration procedure

In order to obtain authorization to receive services, support mobility tracking, and reachability management, the UE needs to register with the network. The UE needs to send a registration request message to an AMF (Access and Mobility Management Function) to initiate a registration procedure when performing the following operations:

initial registration to 5GS (5G System );

when the UE in the CM-CONNECTED or IDLE CM-IDLE state moves out of the registration area, or the UE needs to update the self capability or the protocol parameter negotiated with the network in the registration process, the UE initiates a mobile registration updating process; the UE changes the Preferred Network Behavior (Preferred Network Behavior), resulting in it not being consistent with the Supported Network Behavior (Supported Network Behavior) provided by the serving AMF; or when the UE wishes to retrieve the LADN information;

periodic registration updates (due to predefined timer timeouts);

and (4) emergency registration.

2) Service Request (Service Request) procedure

The UE in CM-IDLE state sends a service request message to the AMF to trigger a request procedure by which the UE can send an uplink signaling message, user data, or a paging request in reply to the network. The AMF may initiate authentication when receiving the service request message. After establishing a signaling connection with the AMF, the UE may send a signaling message by the network, e.g., the UE sends a PDU session setup to the SMF through the AMF.

3) UE configuration update request

When the AMF desires to change the UE configuration, the AMF sends a UE configuration update request message to the UE. The UE configuration information includes:

the parameters related to access and mobility management determined and provided by the AMF specifically include configured NSSAI (Network Slice Selection Assistance Information) and signed S-NSSAI (Single Network Slice Selection Assistance Information) mapped thereto, allowed NSSAI and signed S-NSSAI mapped thereto, Service Gap time, and UE wireless capability ID specified by PLMN (Public Land Mobile Network);

UE policies provided by PCF.

4) Uplink non-access stratum Transport (UL NAS Transport)

The UE sends a UL NAS Transport message to the AMF to initiate a NAS Transport procedure. The purpose of this procedure is to transport the following NAS messages:

a 5GSM (5GS Session Management, 5G Session Management) message;

SMS (Short Messaging Service) messages;

an LPP message;

a transparent container;

one UE policy container.

The 3GPP R17(3rd Generation Partnership Project R17) introduced an NTN (Non-Terrestrial communication network), i.e., a satellite internet, and has the advantages of wide coverage, small influence from natural disasters and physical attacks, and the like. The system can be deeply fused with a ground mobile communication network (5G) network, makes up for the insufficient coverage of the ground mobile network, forms a fused network system with complementary advantages, close fusion and three-dimensional layering with the ground network, and realizes the transmission and interaction of information in the global range.

Since the coverage area of the NTN cell is greatly increased relative to the ground communication, the coverage radius is increased to 200 km. If the geographic position of the terminal does not exist, the accuracy of accessing the NTN network with a large coverage radius by the terminal is greatly reduced, and because the ultra-large coverage radius of the NTN network brings ultra-large time delay of random access and switching, the satisfaction degree of communication QoS is greatly reduced, and meanwhile, the ultra-large time delay also brings reduction of the success rate of random access and switching. In NTN network technology, this is a problem that needs to be solved urgently. For a non-terrestrial communication network, in order to assist a terminal to perform efficient registration, paging, handover, access, and other operations, a core network may want to be able to directly acquire geographical location information of the terminal. If the RAN side base station and the core network can utilize the geographical position information of the ground where the terminal is located, paging, authentication, access and switching of the terminal in a cell under an overlarge coverage radius can be accurately and effectively carried out.

However, at present, the 3GPP R17 core network cannot directly obtain the specific geographical location information of the terminal, and can only directly obtain the approximate location information based on the base station level to which the UE belongs. However, since the coverage radius of the NTN network is changed from 5km to 200km relative to the ground coverage radius, the accuracy of the location information based on the base station level cannot meet the requirement of the core network for the accuracy of the location information of the terminal in the service flows of registration authentication, paging, handover, access, etc. Under the existing 5G network architecture, only through the LMF-based positioning architecture and the LPP process, the core network AMF can obtain accurate geographical location information reported from the terminal. However, since the LMF is an architecture designed based on the LCS client, it is inefficient to simply transmit the geographical information reported by the UE. Only in order to obtain one report message of the UE, firstly the core network AMF and the LMF are required to interact, secondly the terminal is required to enter a connection state, then the terminal can report the position information of the terminal after shaking hands with the LMF for a plurality of times through the LPP flow, and then the position information is provided for the AMF through the LMF. Such a procedure is too inefficient to be suitable for large latency scenarios based on NTN networks simply to deliver a certain location information.

In view of the foregoing problems, embodiments of the present invention provide a method for reporting and acquiring location information, a core network device, and a UE.

In the embodiments of the present invention, a user equipment UE may specifically refer to an access terminal, a subscriber unit, a subscriber station, a mobile station, a remote terminal, a mobile device, a user terminal, a wireless communication device, a user agent, or a user equipment. An access terminal may be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with Wireless communication capability, a computing device or other processing device connected to a Wireless modem, a vehicle mounted device, a wearable device, a Mobile station in a 5G Network, or a subscribing device in a future evolved Public Land Mobile Network (PLMN) Network, etc. The core network equipment in the embodiment of the invention is an AMF entity.

Example 1

The position information acquisition method provided by the embodiment of the invention is applied to core network equipment. As shown in fig. 4, the method includes:

step 401, receiving a message carrying geographical location information sent by a terminal through a message interface between the terminal and the terminal;

the embodiment of the invention increases the message interface between the UE and the core network AMF, and the core network AMF can directly acquire the message carrying the geographical position information from the UE through the message interface.

In this embodiment, the message interface between the UE and the core network device is an interface through which the UE transmits a message to the core network device through the base station, in the message transmitted through the message interface, the geographical location information of the terminal is added, and the location reporting process does not need to pass through complicated signaling interaction, and only needs to directly transmit the message through the message interface. The message carrying the geographical location information may be signaling message in the existing protocol, or may be newly defined message dedicated to transmitting the geographical location information through the message interface.

The UE may determine the accurate geographical location information by using the positioning signal, for example, by using a global positioning system GPS signal, a beidou signal, a wireless communication system, an air pressure sensor, and the like. The process of UE-specific determination of the geographical location information is an existing process and is not described in detail here.

The UE can determine accurate geographical location information by utilizing the positioning signals, and does not need to obtain location information through the complex LMF/AMF.

And 402, executing corresponding operation according to the geographic position information in the message.

After the core network device acquires the geographical location information, corresponding operations related to the geographical location information, such as network access or switching, can be executed, the paging list can be further optimized, the paging range is reduced, and the paging delay is reduced, which is a very effective promotion for the network with the large delay of the NTN.

The core network device may receive, through a message interface with the terminal, a message carrying geographic location information sent by the terminal in any of the following manners:

1) sending a position reporting request to the terminal, and receiving a message which is sent by the terminal based on the position reporting request and carries geographical position information;

the core network device may trigger to send a location reporting request to the terminal periodically or in an event, and the terminal sends a message carrying the geographical location information after receiving the location reporting request from the core network device.

In implementation, the core network is not limited to send the location reporting request to the terminal in the above manner, and may also send the location reporting request to the terminal when determining that the geographical location information needs to be acquired from the terminal as needed.

The position reporting request sent by the core network equipment to the terminal comprises at least one item of information as follows:

a terminal identification ID;

longitude and latitude geographic information of the terminal;

terminal height information;

the terminal timing advances the TA value;

and (5) position precision requirement.

The terminal can send the message carrying the geographical location information according to the location reporting request, for example, according to the location precision requirement, the obtained precise geographical location information is processed and the location information with corresponding precision is reported.

2) Receiving a message which is actively sent by the terminal and carries geographical position information;

the terminal can actively send the message carrying the geographical position information to the core network equipment by adopting an active reporting mode agreed by a protocol, or actively send the message carrying the geographical position information to the core network equipment according to the active reporting mode notified by the core network equipment, the specific terminal can actively send the message carrying the geographical position information after adopting periodic or event triggering, and the core network equipment receives the message carrying the geographical position information after the terminal is triggered periodically or event.

The core network device may notify the active reporting mode of the terminal through a corresponding signaling, and may specifically but not limited to adopt any one or any multiple of the following modes:

the core network equipment informs the terminal to start sending the information carrying the geographical position information by adopting a periodic or event triggering mode by sending a signaling to the terminal, if the terminal is informed to report periodically, the signaling can further carry a periodic value which is reported periodically, and if the terminal is informed to report by event triggering, the signaling can further carry a threshold value which meets the corresponding condition of event triggering;

the core network equipment informs the terminal to cancel sending a message carrying the geographical position information by adopting a periodic or event triggering mode by sending a signaling to the terminal;

the triggering condition reported by the terminal event is updated by sending a signaling to the terminal, and the triggering event can be specifically changed, or the triggering event is unchanged and the condition of the triggering event is updated.

For the core network device to send a location reporting request to the terminal by periodic or event triggering, or after the terminal is triggered by the periodic or event triggering, actively send a message carrying geographical location information to the core network device, and the triggering condition of the event triggering to be satisfied may be any one of the following conditions:

1) the distance between the terminal and the edge of the set area is smaller than a preset distance threshold;

the set area may be, but is not limited to, a cell where the terminal is located, and when the terminal communicates in the cell and moves to a cell edge, if an establishment between the terminal and the cell edge is smaller than a preset distance threshold, an event trigger condition is satisfied.

The set area can also be other designated areas, and when the distance from the terminal to the designated area is smaller than the preset distance threshold, the event triggering condition is met.

2) The difference between the distance between the terminal and the set satellite and the expected distance exceeds a preset distance threshold;

the set satellite can be a designated satellite in a satellite list of terminal communication, the designated satellite can be one or multiple, the terminal calculates the actual distance between the terminal and the designated satellite according to the satellite list, and if the difference value between the actual distance and the expected distance exceeds a preset distance threshold, the terminal is determined to meet the event triggering condition.

The preset distance thresholds in the above modes 1) and 2) may be the same threshold value, or may be set to different threshold values.

3) And the Reference Signal Received Power (RSRP) of the terminal receiving satellite is lower than a preset power threshold.

As an optional implementation manner, the acquiring, by the core network device, the message carrying the geographical location information sent by the terminal includes:

The core network device may receive a message carrying the geographical location information sent by the terminal in an idle state or an Inactive state, and may also receive a message carrying the geographical location information sent by the terminal in a connected state. The core network equipment can perform terminal authentication permission according to the position related information or further optimize a paging list according to the position related information, so that the paging range is reduced, and the paging delay is reduced, which is a very effective promotion for an NTN large-delay network.

When the terminal sends the message carrying the geographical position information in the registration process, the core network equipment authenticates the terminal according to the acquired message carrying the geographical position information sent by the terminal in the registration application. If the authentication fails, the core network equipment sends a registration failure notification message carrying at least one of the following information to the terminal:

a terminal exceeding operation range indication;

And if the terminal sends the message carrying the geographical position information in the idle state or the inactive state, selecting a paging area and informing the corresponding base station according to the obtained message carrying the geographical position information sent by the terminal in the idle state or the inactive state.

step 501, determining geographical position information by using a positioning signal;

the UE may determine accurate geographical location information by using a positioning signal, for example, by using a global positioning system GPS signal, a beidou signal, an air pressure sensor, and the like. The process of UE-specific determination of the geographical location information is an existing process and is not described in detail here.

The UE can determine accurate geographical location information by using the positioning signal, and does not need to go through the complicated procedure of LPP.
