In the prior art, an outdoor positioning technology based on a Global Navigation Satellite System (GNSS) has been widely applied to various fields, and in addition, a high-precision positioning technology based on a fifth generation mobile communication (4G) network also effectively fills a gap in positioning of a Satellite Navigation System.
Currently, a mobile communication network has entered the fifth generation mobile communication (5G) technology era, in a 5G system, nodes on a network side are mostly connected by a wire, that is, 5G base stations (gnbs) are connected by a wire link, and the gnbs (nr nodebs) and core network nodes, such as Access control and Mobility Management functions (AMFs), User Plane Functions (UPFs), etc., are also connected by a wire link.
Please refer to fig. 1 as a 5G Network architecture diagram, in fig. 1, the 5G Network architecture mainly includes a core Network (5GC) and a Radio Access Network (NG-RAN), wherein the core Network mainly includes AMF/UPF, etc., the NG-RAN node mainly includes a gNB and a NG-eNB, the gNB and the NG-eNB are connected through an Xn interface, the gNB/NG-eNB is connected with the AMF through a control plane interface (NG-C interface) between the NG-RAN and the 5GC, and is connected with the UPF through a user plane interface (NG-U interface) between the NG-RAN and the 5 GC. When a User Equipment (UE) communicates with a Radio access network node in a 5G network, the state of the UE is considered by the Radio access network as three Radio Resource Control (RRC) states: RRC _ Inactive, RRC _ CONNECTED, and RRC _ IDLE.
Please refer to fig. 2, which is a schematic diagram of a 5G positioning network architecture, in fig. 2, a Location Management Function (LMF) has the following functions: and positioning calculation is supported, a downlink positioning measurement result or positioning estimation is obtained from the UE in a connection state, and an uplink positioning measurement result, auxiliary data and the like are obtained from the NG _ RAN side to position the UE. In the 5GC, the LMF is connected to the AMF through a BLs interface, the AMF is connected to a Gateway Mobile Location Center (GMLC) through an NLg interface, the GMLC is connected to a Unified Data Management (UDM) through a NLh interface, and the GMLC is further connected to a Location Retrieval Function (LRF), in the 5G Location network architecture, the AMF in the 5GC is connected to an external UE through an N1 interface and to an external NG RAN through an N2 interface, and the GMLC and the LRF are connected to an external service through a Le interface. Therefore, in the 5G network, to locate the UE, the RRC state of the UE in the non-connected state needs to be first changed into the connected state, and then the UE can be located, which inevitably increases signaling overhead and power consumption of the UE.
In view of this, how to reduce signaling overhead when positioning the ue becomes an urgent problem to be solved.

Detailed Description
The embodiment of the invention provides a position reporting method, a wireless access network entity and a computer storage medium, aiming at solving the technical problem of more signaling overhead when positioning a user terminal in the prior art.
In order to solve the technical problems, the general idea of the embodiment of the present application is as follows:
a method for position reporting is provided, which is applied to a base station of a 5G network, and comprises the following steps: receiving a location request message for locating a user terminal; and if the user terminal is in the inactive state, reporting the information of the RAN position area of the radio access network where the user terminal is located to a core network node.
In the above scheme, after receiving the location request message for locating the user terminal, the RAN location area information of the radio access network where the user terminal in the inactive state is located is reported to the core network node, so that the user terminal in the inactive state can complete the corresponding location management function without being activated, thereby effectively reducing signaling overhead required for locating the user terminal, reducing electric quantity consumed by the user terminal due to location activation, and enabling terminal location service under a 5G network architecture to be more efficient and flexible.
In order to better understand the technical solutions of the present invention, the following detailed descriptions of the technical solutions of the present invention are provided with the accompanying drawings and the specific embodiments, and it should be understood that the specific features in the embodiments and the examples of the present invention are the detailed descriptions of the technical solutions of the present invention, and are not limitations of the technical solutions of the present invention, and the technical features in the embodiments and the examples of the present invention may be combined with each other without conflict.
Referring to fig. 3, an embodiment of the present invention provides a method for location reporting, which is applied to a radio access network entity of a 5G network, and the processing procedure of the method is as follows.
Step 301: a location request message for locating a user terminal is received.
Step 302: and if the user terminal is in the inactive state, reporting the information of the RAN position area of the radio access network where the user terminal is located to a core network node.
In the embodiments provided in the present invention, the radio access network entity may be a 5G base station (gNB), a Centralized Unit (CU), or a 4G base station (Evolved Node B, eNB).
After a Radio Access Network entity receives a location request message for locating a User Equipment (UE) from a core Network, if the UE is currently in an Inactive (RRC _ Inactive) state, reporting location area information of a Radio Access Network (RAN) where the UE is located to a corresponding core Network node.
And if the user terminal is in a connection (RRC _ CONNECTED) state currently, reporting the position information of the user terminal to the core network node currently.
It should be noted that, when the ue is in the Inactive (RRC _ Inactive) state, the ue has the following features:
cell reselection mobility, paging initiated by NG-RAN (RAN paging), RAN-based Notification Area managed by NG-RAN, Discontinuous Reception mechanism (DRX) for RAN paging configured by NG-RAN, 5GC-NG-RAN connection (user plane and control plane) established for UE, Access Stratum (AS) context of UE stored in NG-RAN and UE, and Access Notification Area (RAN Notification Area, RNA) where UE is known by NG-RAN.
The RAN location area information includes information of at least two cells in the RAN location area where the user terminal is currently located, or at least one RAN area identification information of the user terminal.
In the embodiment provided by the invention, after receiving the position request message for positioning the user terminal, the information of the radio access network RAN position area where the user terminal in the non-activated state is located is reported to the core network node, so that the user terminal in the non-activated state can complete the corresponding position management function without being activated, thereby effectively reducing the signaling overhead required for positioning the user terminal, reducing the electric quantity consumed by the user terminal due to positioning activation, and enabling the terminal positioning service under the 5G network architecture to be more efficient and flexible.
If the user terminal enters the radio access network entity in the embodiment of the present invention for the first time through moving, before receiving the location request message for locating the user terminal, the method further includes:
receiving an access network notification area RNA updating request message sent by the user terminal; determining that the context information of the user terminal is positioned in an old radio access network entity based on an invalid radio network temporary identifier I-RNTI carried in the RNA updating request message; then, sending a request message for retrieving the context information to an old radio access network entity, and after receiving a response message of the request message, if the reporting type in the position report information is notified when the serving cell is changed, reporting the RAN position area information changed by the user terminal to a core network node through a path updating message; wherein the location report information is carried in the response message.
For example, referring to fig. 4, a flowchart of reporting the location of the user terminal by the radio Access network entity when the user terminal in the inactive state moves to the radio Access network entity, taking as an example that after the user terminal moves from the old radio Access network entity (old gbb) to the radio Access network entity (new gbb) in the embodiment of the present invention, the core network node is an Access control and Mobility management Function (AMF), and the user terminal is currently in the inactive state.
Step 401: the user terminal sends an RNA update request message to the new gNB.
Step 402: and the new gNB determines that the context of the user terminal is positioned in the old gNB according to an Invalid radio network temporary identifier (I-RNTI) carried in the RNA updating request message.
Step 403: the new gbb sends a request message to the old gbb to retrieve the context of the user terminal.
Step 404: and the old gNB returns a response message to the new gNB based on the request message, and the response message also carries the position report information.
After receiving the response message, the new gNB, according to the location report information carried in the response message, if it is determined that the reporting type is the notification when the serving cell is changed, performs step 405.
Step 405: the new gbb sends a path update message to the AMF. If the position of the user terminal is determined to be changed, the path updating message carries RAN position area information after the user terminal is changed, and the RAN position area information comprises information of at least two cells in a RAN position area where the user terminal is located currently or at least one RAN area identification information of the user terminal.
In the embodiment provided by the invention, after the user terminal enters the new radio access network entity from the old radio access network entity, the new radio access network entity needs to send a path updating message to the core network node, if the positioning function of the user terminal is in an inactive state at this time, because the current RAN location area information is reported by the inactive user terminal, the position of the user terminal which is considered to be in the inactive state at this time is changed, and when the radio access network entity which receives the user terminal sends the path updating message to the core network node, if the reporting type is a notification when the cell is changed, the RAN location area information of the user terminal is carried in the path updating message, so that the position reporting message does not need to be sent to the core network node independently, thereby effectively reducing the signaling expense used for carrying out the location management function.
In the embodiments provided by the present invention, the information of the RAN location area of the radio access network where the user terminal is located is reported to the core network node, and there are several possible implementation manners as follows:
in a possible implementation manner, in a process that an RRC state of a user terminal is changed from a CONNECTED (RRC _ CONNECTED) state to an inactive state, if a reporting type carried in a location request message is notified when a serving cell is changed, and a radio access network entity notifies the user terminal to enter the inactive state according to an RRM policy, the changed RAN location area information is reported to a core network node through a location report message.
For example, referring to fig. 5, a flowchart for reporting the location of the ue by the radio access network entity when the ue in the connected state transitions to the inactive state. Assume that the radio access network entity is a gNB and the core network node is an AMF.
Step 501: and the gNB receives a position request message sent by the AMF, wherein the reporting type carried in the position message is notified when the serving cell is changed.
Step 502: and the gNB informs the user terminal to enter an inactive state according to the RRM strategy.
Step 503: the gNB reports the changed RAN location area information to the AMF through a location report message. The RAN location area information includes information of at least two cells in the RAN location area where the user terminal is currently located, or at least one RAN area identification information of the user terminal.
In a possible implementation manner, when the user terminal is in an inactive state, if the reporting type carried in the location request message is direct reporting, the RAN location area information is reported to the core network node through the location report message.
For example, please refer to fig. 6, which is a flowchart illustrating a radio access network entity reporting a location of a ue when the ue is in an inactive state. Assume that the radio access network entity is a gNB and the core network node is an AMF.
Step 601: and the gNB receives a position request message sent by the AMF, wherein the reporting type carried in the position message is direct notification.
After the gNB receives the location request message, it directly reports the location of the ue to the AMF, i.e. step 602 is performed.
Step 602: the gNB sends a location report message to the AMF. The location report message carries information of a RAN location area where the user terminal is located, where the RAN location area information includes information of at least two cells in the RAN location area where the user terminal is currently located, or at least one RAN area identification information of the user terminal.
In a possible implementation manner, when the user terminal is in an inactive state, if the reporting type carried in the location request message is notified when the serving cell is changed, when the RAN location where the user terminal is located changes, or when the RAN location information reported last time is based on that the user terminal is a single serving cell in a radio resource control RRC connection state, the RAN location area information after the change is reported to the core network node through the location report message.
For example, please refer to fig. 7, which is a flowchart illustrating a radio access network entity reporting a location of a ue when the ue is in an inactive state. Assume that the radio access network entity is a gNB and the core network node is an AMF.
Step 701: and the gNB receives a position request message sent by the AMF, wherein the reporting type carried in the position message is notified when the serving cell is changed.
After the serving cell of the user terminal changes, step 702 is executed.
Step 702: the gNB sends a location report message to the AMF. The location report message carries information of a RAN location area where the user terminal is located, where the RAN location area information includes information of at least two cells in the RAN location area where the user terminal is currently located, or at least one RAN area identification information of the user terminal.
For another example, please refer to fig. 8, which is a flowchart illustrating that the radio access network entity reports the location of the ue when the ue is in the inactive state. Assume that the radio access network entity is a gNB and the core network node is an AMF.
Step 801: and the gNB receives a position request message sent by the AMF, wherein the reporting type carried in the position message is notified when the serving cell is changed.
If the location information reported to the AMF by the gNB is single serving cell information based on the RRC CONNECTED state (i.e., RRC _ CONNECTED state), step 802 is executed when the serving cell of the ue changes.
Step 802: the gNB sends a location report message to the AMF. The location report message carries information of a RAN location area where the user terminal is located, where the RAN location area information includes information of at least two cells in the RAN location area where the user terminal is currently located, or at least one RAN area identification information of the user terminal.
In fig. 5-8, the location information of the ue is reported as the core network through the location reporting procedure, however, in the 5G network, there are other NG or S1 proprietary signaling procedures besides the location reporting procedure, and when the location of the ue is to be reported, the location information can also be reported through other NG or S1 proprietary signaling procedures, specifically:
in a possible implementation manner, when the user terminal is in an inactive state, if the reporting type carried in the location request message is notified when the serving cell is changed, and when the RAN location where the user terminal is located changes, and if the base station has other NG or S1 proprietary signaling procedures except for the location reporting procedure, the changed RAN location area information is reported to the core network node through other NG or S1 proprietary signaling except for the location reporting message.
Please refer to fig. 9, which is a fourth flowchart of reporting the location of the ue by the radio access network entity when the ue is in the inactive state. Assume that the radio access network entity is a gNB and the core network node is an AMF.
Step 901: and the gNB receives a position request message sent by the AMF, wherein the reporting type carried in the position message is notified when the serving cell is changed.
If there are any NG or S1-specific signaling procedures between the gNB and the AMF except for the location reporting procedure when the location of the ue changes, step 902 is executed.
