A 5G (5th-generation, fifth-generation mobile communication technology) system includes a variety of application scenarios, and in these application scenarios, it is often necessary to locate each terminal in the scenario. Among them, the large-scale Internet of Things (massive Machine Type of Communication, mMTC) is one of the important scenarios of 5G, and there are a large number of terminal positioning requirements in this application scenario. For example, in a factory or a shopping mall in an mMTC scenario, there are usually a large number of terminals that need to be positioned in the same area. In some other user application scenarios, there are also situations where multiple terminals need to be positioned.

Smart terminal devices such as mobile phones, watches, and glasses carried by users may have positioning requirements.

However, in the current terminal positioning process, when the network performs positioning configuration, the positioning configuration is usually performed in units of terminals, which leads to a large network configuration signaling overhead.

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.

Terminal location-related services can be a network-initiated location request (Network Induced Location Request, NI-LR) initiated from the 5G core network, a terminal location request (Mobile Terminated Location Request, MT-LR) service, or a service initiated from the UE Mobile Originated Location Request (MO-LR) service originating from the terminal. After AMF (Access and Mobility Management Function, Access and Mobility Management Function) receives a location service request for a specific target UE, it will send a location service request to LMF (Location Management Function, local management function). The LMF processes the positioning service request, executes the LPP (LTE POSITIONING PROTOCAL, LTE Positioning Protocol) process and or the NRPPa (NR POSITIONING PROTOCAL a, NR Positioning Protocol a) process, which may include assistance data forwarded to the target UE to assist UE-based and /or UE-assisted positioning, and then the LMF returns the result of the positioning service to the AMF (for example, the predicted position of the UE). In the case of requests from entities other than AMF, such as UE, LCS (Location Service) client, etc., AMF will also return the location service result to the entity.

In the embodiment of the present application, a positioning configuration method is proposed, which is applied to core network equipment to solve the problem of high network configuration signaling overhead in the existing terminal positioning process.

Referring to FIG. 1, FIG. 1 is a flow chart of a positioning configuration method provided in an embodiment of the present application, which is used for core network equipment. As shown in FIG. 1, the method includes the following steps:

Step 101, determine a terminal group of a terminal to be located.

Group the terminals to be positioned to obtain a terminal group;

Core network devices can make decisions on how to group terminals based on the acquired or existing terminal-related information; core network devices can also directly obtain terminal groups according to the grouping information reported by terminals. Directly obtaining terminal groups can be understood as terminal The terminal group information is directly reported, and the core network determines the terminal group reported by the terminal as the terminal group, and performs positioning configuration for the terminals in the determined terminal group in units of groups.

Optionally, the grouping the terminals to be positioned to obtain the terminal group includes: grouping the terminals to be positioned to obtain the terminal group according to at least one of the following information:

Request assistance information (Assistance data) reported by the terminal;

Grouping information provided by the Application Layer;

Information about existing terminals in the core network;

Terminal status related information provided by the access network.

Optionally, the requested auxiliary information reported by the terminal includes at least one of the following: positioning related configuration, positioning requirement and terminal type.

Optionally, the positioning-related configuration includes at least one of the following: positioning configuration beam on/off request, on/off request for positioning reference signal PRS request, positioning configuration information index, PRS configuration, low battery indication, base station/ The number of sending and receiving points TRP (Transmission reception point), positioning start time and valid time of positioning configuration information;

Wherein, the request auxiliary information includes terminal grouping information, which may be that the terminal directly provides the grouping information to the network side, for example, may be an index of a list, wherein the terminal members corresponding to the index may change dynamically. The low battery indication may be indication information sent when the battery power of the terminal is lower than a preset power value.

Wherein, the requested auxiliary information reported by the terminal may be reported in the LPP process, or may be reported in other signaling processes.

The application layer can directly indicate the grouping information to the core network, for example, in emergency rescue, designate each terminal configured by the search and rescue team as a terminal group. The above application layer may be the application layer of the terminal, or the application layer of other servers. The grouping information provided by the application layer may directly include terminal group information, and the core network obtains the terminal group from the terminal group information provided by the application layer, that is, the terminal group provided by the application layer is used as the terminal group for positioning configuration.

The existing terminal-related information of the core network may be the terminal-related information reported by the terminal when the terminal is attached to the network, or it may be the terminal-related information reported by the terminal to the network in other processes, for example, the mobile phone terminal of the same user , watches, earphones and other Redcap terminals as a group.

The information related to the terminal state provided by the access network may be the connection state of the terminal reported by the access network to the core network, for example, the RRC state of RRC connected state, idle state, and deactivated state.

The core network requests auxiliary information, grouping information provided by the application layer, existing terminal location-related information and/or terminal status-related information. Group the terminals according to the combination of factors or factors, and perform a unified positioning configuration for each group of terminals after grouping.

For example, terminals that have the same positioning accuracy requirements in the same cell can be grouped into one group.

For example, in the mMTC scenario, a large number of terminals of the same type are usually placed in the same area in a factory or a shopping mall, and these terminals have relatively consistent requirements for location services. information, and/or terminal state related information, the above-mentioned terminals are divided into the same terminal group, and a unified positioning configuration is performed on them. Assuming that multiple terminals in the aforementioned factory or shopping mall only need to locate a rough range, the positioning configuration can configure the measurement results of each terminal in the terminal group to determine whether the terminal is within the range configured by the network.

Information about the signal quality of the terminals in the terminal group;

Request auxiliary information reported by terminals in the terminal group;

Information about existing terminals in the core network;

Terminal state related information provided by the access network;

The grouping information reported by the terminal; or, the determination of the group leader terminal of the terminal group includes:

Randomly select and determine the group leader terminal of the terminal group.

For example, in Redcap UE, multiple terminals may be carried by the same user, and the terminals carried by the same user can be determined as a terminal group. Assuming that the terminal group does not need precise positioning, the positioning configuration can configure the terminal group leader to perform measurement reporting, and use the terminal group leader's measurement results as the positioning reference for the entire group of terminals.

For example, the existing terminal-related information on the core network is that the mobile terminal of the same user reported by the terminal is the team leader, and other Redcap terminals such as watches and earphones are team members.

For example, in emergency rescue, the application layer can designate a terminal of a member of the rescue team as the leader terminal in the terminal group.

Optionally, according to the grouping information reported by the terminal, the group leader terminal of the terminal group is determined. It may be that the terminal reports the specified group leader terminal while reporting the terminal group, and the core network uses the group leader terminal reported by the terminal as the group leader terminal.

It can be understood that, when the core network determines the terminal group by obtaining the terminal group from the grouping information reported by the terminal, the core network may also determine the terminal group based on information related to the signal quality of the terminal in the terminal group and the auxiliary information reported by the terminal in the terminal group. At least one of the sequence information, the request auxiliary information reported by the terminals in the terminal group, the existing terminal related information of the core network, the terminal status related information provided by the access network, and the related information of the terminal group indicated by the application layer are used as reference information. The group leader terminal of the terminal group is determined, or the core network also randomly selects and determines the group leader terminal of the terminal group.

It can be understood that the aforementioned core network may, based on information related to signal quality of terminals in a terminal group, sequence information of requesting auxiliary information reported by terminals in a terminal group, requesting auxiliary information reported by terminals in a terminal group, and existing terminal-related information in the core network, The information related to the terminal state provided by the access network, the application layer instructs to determine the related information of the terminal group, one item of this information determines the group leader terminal of the terminal group, and the group leader terminal of the terminal group can also be determined comprehensively according to the combination of multiple items .

Optionally, the core network LMF groups the terminals to be positioned.

Step 102. Determine the positioning configuration information or the positioning configuration information index of the terminal group.

The positioning configuration information index maps a group of positioning configuration information. The specific mapping relationship can be determined in advance, and the network can notify the terminal of the mapping relationship in advance. When the subsequent network indicates the positioning configuration information, it only needs to indicate the positioning configuration information index. , which can further save signaling overhead.

Each terminal member in the same group of terminals is configured to have the same positioning configuration information or positioning configuration information index. However, a terminal group is not limited to a corresponding set of positioning configuration information or a positioning configuration information index. Optionally, a terminal group has one or more sets of positioning configuration information; or, the positioning configuration information index is one or Multiple, correspondingly, each terminal in the terminal group also has one or more sets of positioning configuration information, or one or more positioning configuration information indexes.

When the terminal has multiple sets of positioning configuration information or multiple positioning configuration information indexes, which set of positioning configuration information or which positioning configuration information index to use can be determined by further instructions from the network side, or can be determined by the effective time corresponding to the positioning configuration information Or valid time configuration is determined.

Step 103: Send the positioning configuration information or the positioning configuration information index corresponding to the terminal group to the access network device, so that the access network device sends the positioning configuration information or the positioning configuration information index to the terminal group.

Wherein, the positioning configuration information or positioning configuration information index corresponding to the terminal group is sent to the access network device, optionally, there is an identifier in a group unit.

A unified positioning configuration can be performed for the same group of terminals, and only one positioning configuration needs to be delivered to the access network device for a group of terminals, so that the access network device sends the positioning configuration information or positioning configuration information index to the terminal group.

Optionally, the core network LMF delivers the same configuration to the same terminal group.

The positioning configuration method in this embodiment determines the terminal group of the terminal to be positioned, and can perform unified positioning configuration for the same group of terminals. For a group of terminals, only one positioning configuration needs to be issued to the access network, which can be used during the positioning process. , saving the signaling overhead of interaction between the core network and the access network.

Referring to FIG. 2, FIG. 2 is a flow chart of a positioning configuration method provided in an embodiment of the present application, which is used for access network equipment. As shown in FIG. 2, the method includes the following steps:

Step 201, receiving positioning configuration information or positioning configuration information index corresponding to a terminal group.

Step 202: Send the positioning configuration information or the positioning configuration information index to terminals corresponding to the terminal group.

Wherein, the LTE positioning protocol (LTE Positioning Protocol, LPP) message includes 8 types, which are respectively capability request message (RequestCapabilities message), capability provision message (ProvideCapabilities message), assistance information request message (RequestAssistanceData message), assistance information provision Message (ProvideAssistanceData message), location information request message (RequestLocationInformation message), location information provision message (ProvideLocationInformation message), abort message, error message.

Optionally, before sending the paging message to the terminal corresponding to the terminal group, it includes:

Wherein, before sending a paging message to a terminal corresponding to the terminal group may refer to sending a paging message to a terminal corresponding to the terminal group before sending a paging message in the case of only sending a paging message; it may also refer to sending a paging message In the case of a system message, before sending a paging message to a terminal corresponding to the terminal group.

By sending a paging advance indication PEI, a wake-up signal WUS, or an indication message for indicating whether to receive a subsequent paging message carried by a PDCCH, a specific terminal can be instructed to receive a paging message, so that the positioning configuration information or positioning information of a specific terminal group The configuration information index is sent to each terminal in a specific terminal group in a targeted manner, which can reduce the power consumption of the interaction between the access network and the terminal.

Similarly, by using the above-mentioned broadcasting method, the positioning configuration information or the positioning configuration information index of a specific terminal group can also be targetedly sent to each terminal in the specific terminal group.

Sending the positioning configuration information or the positioning configuration information index to the terminals corresponding to the terminal group through a system message may be sending the positioning configuration information or the positioning configuration information index to a group of terminals in a certain cell group.

Optionally, the configuration delivered by the access network to the terminal also includes a group list, so that the terminal can know the information of other member terminals of its terminal group.

It should be noted that this embodiment is an implementation manner of an access network corresponding to the embodiment shown in FIG. 1 , and its specific implementation manner may refer to relevant descriptions in the embodiment shown in FIG. 1 . To avoid repeated descriptions , which will not be described in detail in this embodiment.

In the positioning configuration method in this embodiment, the access network receives the positioning configuration information or the positioning configuration information index from the core network in the form of packets, which can save signaling overhead for interaction between the core network and the access network during the positioning process.

Referring to FIG. 3, FIG. 3 is a flowchart of a positioning method provided by an embodiment of the present application, which is used for a terminal. As shown in FIG. 3, the method includes the following steps:

Wherein, the positioning measurement method may adopt sidelink (sidelink), RTT (Round Trip Time, round trip delay), Bluetooth and other measurement methods, but is not limited to the above methods.

In the case of no network coverage, the terminal can still use sidelink, Bluetooth, RTT and other methods to perform positioning measurement according to the existing configuration, and confirm that the group members have not dropped out from within the group. For example, when the cellular network collapses in a natural disaster, the fire squad or rescue team, or the convoy traveling in an area without cellular network coverage in the wild, the terminals in the terminal group can confirm that the group members have not fallen off according to the terminal positioning measurement.

Optionally, performing the positioning measurement according to the positioning configuration information or the positioning configuration information index includes: determining at least one of the following information according to the positioning configuration information or the positioning configuration information index:

Optionally, during the grouping process, the core network simultaneously determines the terminal group leader and notifies the UE of the terminal group leader information. Specifically, the UE may be notified of the terminal group leader information through positioning configuration information.

According to different positioning requirements of terminal groups, the positioning configuration information or the positioning configuration information index determines different measurement result requirements. For example, when a terminal in a terminal group requires precise positioning, determine the position of the terminal as the measurement result; Whether the distance between the group leader terminals is within the range configured by the network is determined as the measurement result.

Optionally, after the positioning measurement is performed according to the positioning configuration information or the positioning configuration information index, the method further includes: reporting a measurement result.

Wherein, the reported measurement result may be at least one of the above information determined according to the positioning configuration information or the positioning configuration information index.

In UE-assisted positioning mode, the terminal needs to report the measurement result to the network side, and the network side finally determines the terminal positioning information, and returns the positioning service result to the positioning requesting entity (if AMF is used as the requesting entity, it does not need to be returned). In the UE-based positioning mode, the terminal directly determines the positioning result according to the positioning configuration information or the positioning configuration information index without reporting.

Optionally, the reporting of measurement results includes:

Report measurement results to the network side;

The results can be reported by each terminal separately and directly reported to the network side, or can be reported to the group leader terminal after each measurement, and the group leader terminal uniformly reports to the network side, that is, indirectly reports to the network side. Optionally, the group leader terminal may report the measurement results of all UEs in the group to the network side, or may report only the measurement results of the group leader terminal.

Report at least one of the following measurements:

Measurement results of all terminals in the terminal group;

Optionally, if the capabilities or states of the terminals in the terminal group are different, the measurement results can be determined to be reported to the terminals according to the strength of the terminals in the terminal group, or the measurement results can be determined to be reported to the terminals according to the communication status of the terminal group, so as to select the terminal Terminals with stronger capabilities or better communication status in the group report results to save energy consumption of other terminals.
