Description

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a positioning method, an apparatus, a terminal, an access network device, and a core network device.

Background

In the prior art, an LMF (Location Management Function) is a positioning server, and is responsible for selecting a positioning method and triggering corresponding positioning measurement, and may calculate a final positioning result and accuracy. The NG-RAN (5G radio access network) may send positioning reference signals or make positioning measurements based on assistance information. The terminal device may send a positioning reference signal, or perform positioning measurement based on the auxiliary information, or calculate a final positioning result and accuracy based on the measurement result.

The Positioning capability in LPP (LTE Positioning Protocol) includes a Positioning method supported by a target device, different aspects supported by a certain Positioning method (such as supported assisted global navigation satellite Positioning system a-GNSS assistance data types), and common characteristics of some Positioning not limited to a certain Positioning method (such as capability of processing multiple LPP transactions).

In the 5G positioning technology, the positioning of the connected terminal is mainly supported, and for the positioning of the idle and inactive terminals, the positioning request can be supported only by entering the terminal into the connected state, so as to complete the positioning task. With the increasing number of positioning terminals in the network, after more terminals of the internet of things type enter the network, if only the terminal positioning in the connected state is supported, the greater challenges in the aspects of network resources and the like can be met. With the positioning requirement of a large number of terminals accessing a network, the consumption of NR network resources may be large in some scenarios, and thus terminals supporting simultaneous positioning services by the network are very limited.

In the embodiment of the invention, after receiving the positioning paging message, the terminal finds that the positioning paging message is in an idle state or an inactive state, and the terminal does not enter a connected state to respond to paging any more, but maintains the existing idle state or the inactive state and starts to perform positioning service.

In the embodiment of the invention, the terminal acquires corresponding positioning auxiliary information through the broadcast message, and performs positioning measurement and calculation based on the terminal or positioning measurement based on terminal assistance according to the idle state or inactive state positioning request information in the positioning paging message.

Further, after the positioning measurement and calculation work is finished, the method further comprises the following steps:

For example, the terminal actively enters a connected state, and sends a measurement result or a calculation result to the core network device, and the core network device may further send a measurement record or a calculation result reported by the terminal to the location server LMF, thereby completing the location of the terminal in an idle state or an inactive state.

As another optional embodiment, the location paging message further includes:

It should be noted that, the positioning server selects the positioning method information of the terminal for the terminal, and sends the information to the core network device, and the core network device sends the information to the access network device, and the access network device sends the information to the terminal, where the information is carried in the positioning paging message.

Wherein the positioning capability information comprises at least one of:

supporting positioning in an idle state or an inactive state;

Bearing in mind the above example, the method further comprises:

sending a Radio Resource Control (RRC) request message to access network equipment; the RRC request message carries a positioning paging response. That is, after receiving the location paging message, the terminal finds that it is an idle state or inactive state location request service, and the terminal initiates a random access process and feeds back a location paging response to the access network device through the RRC request message.

In summary, in the embodiment of the present invention, when the terminal is in the idle state or the inactive state and only has a positioning service, the network notifies the terminal to perform the positioning service through the positioning paging message, and the terminal directly performs positioning measurement and calculation in the idle state or the inactive state without entering the connected state, thereby implementing the positioning of the terminal in the idle state or the inactive state.

As shown in fig. 3, an embodiment of the present invention further provides a positioning method, which is applied to an access network device, and includes:

step 31, receiving a positioning paging message sent by a core network device, where the positioning paging message includes: identification of the terminal and positioning request information in an idle state or an inactive state;

The access network equipment receives the positioning paging message sent again by the core network equipment, pages the terminal in the paging area and carries the required positioning method information. Similarly, after receiving the location paging message, the terminal finds that the location paging message is idle or inactive, and the terminal will not enter a connected state to respond to paging, but maintain the existing idle or inactive state and start to perform a location service.

As shown in fig. 4, an embodiment of the present invention further provides a positioning method, which is applied to a core network device, and includes:

step 41, sending a positioning paging message to the access network device, where the positioning paging message includes: the identification of the terminal and the positioning request information in an idle state or an inactive state. And the access network equipment sends the positioning paging message to the terminal.

For example, when the core network device receives a positioning request, the positioning request is sent to the positioning server in combination with the positioning capability information supported by the terminal in the idle state or the inactive state reported by the terminal. The positioning server determines whether to position the terminal in an idle state or an inactive state by combining with a positioning request (such as quality of service (QoS), terminal positioning capability information, access network equipment capability and the like). If the terminal is determined to be positioned in an idle state or an inactive state, the positioning server selects a suitable positioning method for the terminal (such as a positioning method based on terminal positioning or terminal-assisted positioning, a certain positioning method of an A-GNSS, or a certain positioning method based on a cellular network). The positioning server carries the positioning method information of the terminal in an idle state or an inactive state through the first positioning request message and sends the positioning method information to the core network equipment.

Bearing the above example, when the core network device sends the location paging message, the location paging message further includes:

positioning in an idle state or an inactive state;

As an alternative embodiment, before step 41, the method further comprises:

supporting positioning in an idle state or an inactive state;

Further, the method further comprises:

As another alternative, after step 41, the method further comprises:

Alternatively, the method further comprises:

according to the positioning paging failure information, sending a positioning paging message to the terminal again (namely, the core network equipment initiates secondary paging to carry out whole-network paging terminal) and starting a feedback waiting timer;

To sum up, the embodiment of the present invention provides a method for a terminal to perform a positioning service in an idle state or an inactive state; the terminal can respond to the positioning request service in an idle state or an inactive state under the condition of no other service, and perform positioning measurement or position calculation; the network can support massive terminal positioning services; and the problem that the standby time is limited due to excessive power consumption because the terminal continuously enters a connected state to perform positioning service due to failure of positioning position can be solved.

In order to more clearly describe the positioning method provided by the embodiment of the present invention, the following description is made with reference to several examples.

Example 1

1. When the terminal initially registers, the terminal reports the positioning capacity information of the terminal (IDLE state or Inactive state), and the core network device stores the positioning capacity set reported by the terminal in the user data. The positioning capability information at least comprises one or more of the following information:

support for IDLE state (i.e., IDLE state) positioning capabilities;

supporting an IDLE state based on a terminal positioning method;

supporting all positioning methods of an IDLE state A-GNSS based terminal positioning;

supporting Inactive DL-TDOA based on terminal assisted positioning;

supporting Inactive DL-ECID based on terminal assisted positioning;

and supporting the UL positioning capability of Inactive based on terminal auxiliary positioning.

2. When the core network equipment receives the positioning service request, the stored positioning capability set of the corresponding terminal together with the relevant positioning service information (including QoS and the like) such as the positioning request is sent to the positioning server LMF.

3. After receiving the positioning request and the terminal positioning capability information, the positioning server LMF determines a proper positioning method according to the QoS requirement of the positioning service and the terminal and network capabilities. If it is determined that the terminal is located in IDLE/Inactive state, then suitable location method information includes one or more of the following without limitation:

positioning in an IDLE/active state;

each positioning method of the IDLE/active state based on terminal positioning A-GNSS;

an IDLE/Inactive state is based on a terminal location DL-TDOA location method;

an IDLE/Inactive state is based on a terminal positioning DL-AOD positioning method;

the IDLE/Inactive is based on UL-TDOA of terminal auxiliary positioning;

the IDLE/Inactive is based on the UL-AOA of terminal auxiliary positioning;

IDLE/Inactive is based on the Multi-RTT of terminal assisted positioning.

4. And if the location server LMF determines that the terminal is located at the IDLE/Inactive state, sending the requirement of the IDLE/Inactive state location method to the core network equipment. If the location server LMF determines that the terminal is located in the connected state, an LPP procedure (existing procedure, not described here) is initiated.

5. When the core network receives an IDLE/Inactive state positioning request from a positioning server LMF, the terminal is paged through a paging process, and positioning method information is carried in a positioning paging message and indicated to an anchor point base station. The positioning method carried in the paging message includes, but is not limited to, the positioning method information sent by the positioning server to the core network device.

6. After receiving the positioning paging message carrying the positioning method information, the base station starts paging the terminal in the paging area.

7. After receiving the positioning paging message, the terminal finds that the service is IDLE/Inactive state positioning request service, and the terminal initiates a random access process and feeds back a paging response to the base station through an RRC request message. The terminal will not enter the connection state any more, but still keep the current IDLE state or inactive state, start to perform the positioning service, and perform the positioning service. The RRC request message carries a positioning response identifier.

8. And after receiving the positioning paging response from the terminal, the base station feeds the response back to the core network, and the paging is finished.

9. If the paging fails and the core network does not receive the paging feedback all the time, initiating secondary paging and carrying out the paging terminal of the whole network.

6. After receiving the positioning paging message carrying the positioning method information, the base station finds that the paging request is based on the IDLE/Inactive state positioning service, so that the base station initiates a special positioning paging message, starts paging the terminal in a corresponding paging area, and starts a corresponding timer to wait for the terminal paging feedback information. The location paging message is dedicated to paging location service terminals.

7. When the terminal receives the special positioning paging message from the network, the terminal finds that the terminal is the IDLE/active state positioning request service, enters the random access process, and transmits a positioning paging response indication to the base station on the RRC request signaling. The feedback has received a location paging request.

8. And after receiving the paging feedback, the base station sends the feedback to the core network, and the paging is finished.
