[0036] Please refer to Figure 1 This illustration shows a schematic diagram of the structure of a wireless communication system provided in an embodiment of this disclosure. Figure 1 As shown, the wireless communication system is a communication system based on cellular mobile communication technology. The wireless communication system may include: several UEs 11 and several access devices 12.

[0037] UE11 can be a device that provides voice and / or data connectivity to a user. UE11 can communicate with one or more core networks via a Radio Access Network (RAN). UE11 can be an IoT UE, such as a sensor device, a mobile phone (or "cellular" phone), and a computer with an IoT UE. For example, it can be a fixed, portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted device. Examples include a station (STA), subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, user agent, user device, or user equipment (UE). Alternatively, UE11 can be a device in an unmanned aerial vehicle (UAV). Alternatively, UE11 can be a vehicle-mounted device, such as a vehicle computer with wireless communication capabilities, or a wireless communication device connected to an external vehicle computer. Alternatively, UE11 can also be a roadside device, such as a street light, traffic light, or other roadside device with wireless communication capabilities.

[0038] Access device 12 can be a network-side device in a wireless communication system. This wireless communication system can be a 4G system (also known as Long Term Evolution, LTE); or it can be a 5G system (also known as a New Radio, NR, or 5G NR system). Alternatively, it can be the next generation after 5G. In this case, the access network in the 5G system can be called NG-RAN (New Generation-Radio Access Network). Alternatively, it can be an MTC system.

[0039] The access device 12 can be an evolved NB (eNB) used in a 4G system. Alternatively, the access device 12 can also be a gNB (gNB) using a centralized-distributed architecture in a 5G system. When the access device 12 adopts a centralized-distributed architecture, it typically includes a central unit (CU) and at least two distributed units (DUs). The central unit is equipped with a protocol stack of the Packet Data Convergence Protocol (PDCP) layer, the Radio Link Control (RLC) layer, and the Media Access Control (MAC) layer; the distributed units are equipped with a physical (PHY) layer protocol stack. This disclosure does not limit the specific implementation of the access device 12.

[0040] Access device 12 and UE11 can establish a wireless connection via a wireless air interface. In different implementations, the wireless air interface is a wireless air interface based on the fourth-generation mobile communication network technology (4G) standard; or, the wireless air interface is a wireless air interface based on the fifth-generation mobile communication network technology (5G) standard, such as a new air interface; or, the wireless air interface can also be a wireless air interface based on a next-generation mobile communication network technology standard based on 5G.

[0041] In some embodiments, UE11 can also establish E2E (End to End) connections. Examples include V2V (vehicle to vehicle), V2I (vehicle to Infrastructure), and V2P (vehicle to pedestrian) communication scenarios in vehicle-to-everything (V2X) communication.

[0042] In some embodiments, the wireless communication system described above may further include a network management device 13.

[0043] Several access devices 12 are connected to network management device 13. Network management device 13 can be a core network device in a wireless communication system, such as a Mobility Management Entity (MME) in an Evolved Packet Core (EPC). Alternatively, it can be other core network devices, such as a Serving Gateway (SGW), a Public Data Network Gateway (PGW), a Policy and Charging Rules Function (PCRF), or a Home Subscriber Server (HSS). The implementation of network management device 13 is not limited in this embodiment.

[0044] like Figure 2 As shown, this disclosure provides an information processing method, which is executed by a user equipment (UE), the method comprising:

[0045] S110: Receive indication information; wherein the indication information indicates whether the UE is allowed to send an on-demand PRS request.

[0046] The UE can be a UE capable of receiving Positioning Reference Signaling (PRS). For example, the UE can receive PRS in RRC (Radio Resource Control) connected state or RRC inactive state.

[0047] This indication information can come from access network equipment, such as a base station, or from core network equipment, such as an LMF (Location Management Function). It is transmitted from the core network to the UE via the base station; for example, the indication information is transmitted from the core network's LMF to the UE via the base station.

[0048] After receiving the indication information, the UE can know whether the network side allows the UE to send the on-demand PRS request or prohibits the UE from sending the on-demand PRS request. The on-demand PRS request is a request from the UE to the network side for PRS configuration.

[0049] PRS configuration includes, but is not limited to, one of the following:

[0050] PRS resource configuration; this resource configuration includes, but is not limited to: time-domain resource configuration and / or frequency-domain resource configuration;

[0051] PRS transmission count configuration;

[0052] PRS start and end transmission times;

[0053] Of course, the above is just an example of PRS configuration, and the actual implementation is not limited to the above example.

[0054] If the network side prohibits (i.e. does not allow) the UE to send the on-demand PRS request, the UE can avoid sending the on-demand PRS request to the network device, thereby reducing unnecessary signaling overhead and interference from the radio environment.

[0055] If the network allows the UE to send an on-demand PRS request, the UE can send an on-demand PRS (Request PRS) request to the network device to request PRS configuration, depending on its own situation. For example, if the UE has received a pre-configured PRS configuration from the network, but wants an alternative PRS configuration to reduce its high-power state for power saving purposes, it can use the on-demand PRS request to request the network device to update the PRS configuration. In this case, the UE can also include its desired PRS configuration in the on-demand PRS request, informing the network device of this. Then, when the network device determines that a PRS configuration update is needed, it will update the PRS configuration provided to the UE according to the UE's desired PRS configuration indicated in the on-demand PRS request.

[0056] Of course, the above are just examples, and the actual implementation is not limited to the examples above.

[0057] In summary, in one embodiment, the method further includes:

[0058] When the indication information indicates that the UE is allowed to send the on-demand PRS request, the on-demand PRS request is sent to the network device when the UE expects to request PRS configuration or update PRS configuration;

[0059] or,

[0060] When the indication information indicates that the UE is prohibited (i.e. not allowed) from sending the on-demand PRS request, the on-demand PRS request is not sent to the network device. The network device includes, but is not limited to, the LMF. That is, the indication information can indicate that the UE is allowed to send the on-demand PRS request to the LMF, or that the UE is prohibited from sending the on-demand PRS request to the LMF.

[0061] In one embodiment, S110 may include:

[0062] Receive the indication information sent by LMF;

[0063] or,

[0064] The indication information sent by the base station is received.

[0065] For example, the LMF sends this indication information to the UE, and the UE will receive the message sent by the LMF transparently transmitted by the base station. Exemplarily, the LMF can send an LPP message to the UE, which carries the indication information. LTE is an abbreviation for Long Term Evolution (LTE).

[0066] For example, the base station first receives the indication information from the LMF (Local Management Message), and then, instead of transmitting it transparently, it sends it to the UE at an appropriate time. Therefore, the UE receives the indication information from the base station. For instance, the base station sends it to the UE through various broadcast messages. Exemplarily, the UE receives a system message containing the indication information sent by the base station. This system message can be a Master Information Block (MIB), or it can be another System Information Block (SIB) x, where the value of x can be any positive integer, or it can be a location system message.

[0067] Therefore, in some embodiments, S110 may include: receiving a Long Term Evolution Positioning Protocol (LPP) message containing the indication information sent by the LMF;

[0068] or,

[0069] Receive a system message containing the indication information sent by the base station.

[0070] The LPP messages include, but are not limited to: receiving LPP Provide Assistance data messages sent by LMF, or receiving LPP Provide Pre-Defined PRS configuration messages sent by LMF.

[0071] In some embodiments, if the LMF has predefined PRS configuration for the UE, it can be sent to the UE via an LPP message. This indication information can be carried in the same message as the predefined PRS configuration. For example, an LPP message containing the predefined PRS configuration includes, but is not limited to, an LPP providing auxiliary data message or an LPP providing predefined PRS configuration message. When the UE is allowed to send an on-demand PRS request, the on-demand PRS request sent by the UE may include information about the UE obtaining the predefined PRS configuration.

[0072] In one embodiment, the indication information indicates one of the following;

[0073] The UE is permitted to send the on-demand PRS request;

[0074] or,

[0075] The UE is not allowed to send the on-demand PRS request.

[0076] In this case, the indication information includes one or more indication bits that individually indicate whether the UE is prohibited from sending on-demand PRS requests or allowed to send on-demand PRS requests.

[0077] For example, the indication information may include an indication bit, where one of the two bit values, "0" and "1", indicates that the UE is prohibited from sending on-demand PRS requests, and the other indicates that the UE is allowed to send on-demand PRS requests. When the UE receives this indication information, it can determine whether the network side allows it to send on-demand PRS requests without relying on other information.

[0078] Of course, this indication information can use multiple bits in the same field as other information. Different bit values ​​in this field can indicate different content. In this way, the indication information can share a field with other information, thereby reducing the bit overhead of various information exchanged between the network device and the UE.

[0079] In one embodiment, the indication information indicates one of the following:

[0080] When the UE obtains the PRS configuration, the UE is allowed to send the on-demand PRS request;

[0081] When the UE obtains the PRS configuration, the UE is not allowed to send the on-demand PRS request;

[0082] When the UE has not obtained the PRS configuration, the UE is allowed to send the on-demand PRS request;

[0083] When the UE has not obtained the PRS configuration, the UE is not allowed to send the on-demand PRS request.

[0084] The PRS configuration can be a predefined PRS configuration or any pre-obtained PRS configuration other than the predefined PRS configuration.

[0085] In another embodiment, the indication information indicates one of the following:

[0086] When the UE obtains the predefined PRS configuration, the UE is allowed to send the on-demand PRS request;

[0087] When the UE obtains the predefined PRS configuration, the UE is not allowed to send the on-demand PRS request;

[0088] When the UE has not obtained the predefined PRS configuration, the UE is allowed to send the on-demand PRS request;

[0089] When the UE has not obtained the predefined PRS configuration, the UE is not allowed to send the on-demand PRS request.

[0090] In this embodiment, the indication information cannot be used alone to determine whether the UE is allowed to send an on-demand PRS request. After receiving the indication information, the UE needs to make a comprehensive determination based on whether the network side has issued a predefined PRS configuration. For example, the indication information can also be one or more bits, and different bit values ​​have different meanings. Assuming the indication information occupies one bit, it has bit values ​​"0" and "1". Even if the indication information has the same bit value, the indication result may be different depending on whether the UE has obtained the predefined PRS configuration.

[0091] In some embodiments, the LMF can provide the UE with predefined PRS configuration via LPP auxiliary data messages or via positioning system messages. In some embodiments, the predefined PRS configuration and indication information can be received from the network device in a single message or via different messages.

[0092] The indication information may be an implicit indication from a predefined PRS configuration. In this scenario, if the UE obtains the predefined PRS configuration, it can be assumed that the network device allows the UE to send an on-demand PRS request; or, if the UE does not obtain the predefined PRS configuration, it can be assumed that the network device does not allow the UE to send an on-demand PRS request.

[0093] For example, if the protocol stipulates that the UE is allowed to send on-demand PRS requests when it receives a predefined PRS configuration, then when the UE receives the PRS configuration configured by the network side, it will consider that it is allowed to send on-demand PRS requests to network devices such as LMF; otherwise, it will consider that it is not allowed to send on-demand PRS requests to LMF, etc.

[0094] like Figure 3 As shown, this disclosure provides an information processing method, executed by a UE, the method comprising:

[0095] S210: Receive area information, wherein the area information indicates the effective area range.

[0096] The effective area range is the geographical range within which the indication information indicating whether the UE is allowed to send on-demand PRS requests is effective.

[0097] In some embodiments, the indication information may be received by the UE from a network device, such as from an LMF or from a base station.

[0098] In other embodiments, the indication information may be protocol-defined, so that the UE can obtain the indication information from the protocol file.

[0099] After receiving the area information, the UE needs to determine whether it is within the effective area indicated by the area information. Only if it is within the corresponding effective area will it determine whether the network device allows it to send an on-demand PRS request based on the indication information.

[0100] When a UE moves outside the effective area indicated by the area information, it will no longer rely on that indication to determine whether it is permitted to send on-demand PRS requests. If the area information comes from a network device, it can be carried in the same message as the indication information or in separate messages sent to the UE. Thus, the UE may receive both the indication information and the area information in a single message, or it may receive them separately in different messages.

[0101] For example, area information can also be carried in an LPP message from the LMF or a system message from the base station. If the UE receives both indication information and area information in a single message, the UE will know whether it is permitted to send an on-demand PRS request within the corresponding area.

[0102] For example, the receiving area information includes: receiving an LPP message containing the area information sent by the LMF; the LPP message includes, but is not limited to: an LPP providing auxiliary data message or a predefined PRS configuration message;

[0103] Alternatively, receive a message from the base station that contains the regional information system information.

[0104] Indication information and area information can come from the same network device, for example, from both the LMF and the base station.

[0105] The area information includes one of the following:

[0106] Community Identifier ID;

[0107] Sending and receiving point ID;

[0108] System message SI area ID;

[0109] Radio access network Notification Area (RNA) ID.

[0110] A region information includes one or more cell IDs, and the cell IDs contained in the region information indicate the effective area range of the information.

[0111] A region information entry may include one or more Transmission Reception Point (TRP) IDs. The TRP ID included in the region information indicates the coverage area of ​​the TRP, which is the effective area range of the information.

[0112] The system message area ID is the effective area of ​​some system messages that span cells or block base stations. If the area indicated by the system message area ID included in the area information is the effective area range of the indicated information.

[0113] The RNA ID indicating the RNA can be a region of a paging RRC-inactive UE. In this embodiment of the disclosure, the RAN indicated by the RNA ID included in the region information is the effective range of the indication information.

[0114] In this way, by receiving the effective information, one can also know the geographical scope of the effective information.

[0115] If the effective area of ​​an instruction message is larger than that of a single cell, then an instruction message can be effective in multiple cells, reducing the high signaling overhead caused by sending instruction messages to each cell individually.

[0116] In some embodiments, the effective area range of the indication information can be predetermined, for example, predetermined in a protocol. In this case, after receiving the indication information, the UE determines the effective area range of the indication information according to the predetermined agreement, and no longer receives area information from the network device.

[0117] For example, the protocol stipulates that the scope of the indication information may be a range such as an RNA or a tracking area (TA).

[0118] The method further includes:

[0119] When the UE is determined to be within the effective area of ​​the indication information based on the area information, it is determined whether the UE is allowed to send an on-demand positioning reference signal (PRS) request based on the indication information.

[0120] like Figure 4 As shown, this disclosure provides an information processing method, wherein the method is executed by an LMF, and the method includes:

[0121] S310: Send indication information, wherein the indication information indicates whether the UE is allowed to send an on-demand PRS request.

[0122] The LMF can send this indication information to the UE or the base station. For example, the LMF can send the indication information directly to the UE via an LPP message. Alternatively, the LMF can send the indication information to the base station, which then forwards it to the UE.

[0123] For example, S310 may include:

[0124] Send an LPP message containing the indication information to the UE;

[0125] or,

[0126] Send an NRPPa message containing the indication information to the base station, wherein the indication information is intended to be sent by the base station to the UE.

[0127] The LPP message includes, but is not limited to, LPP Provide Assistance data messages or provide pre-defined PRS configuration messages.

[0128] The NRPPa message includes, but is not limited to, an NRPPa location information request message. This NRPPa location information request message can also be used to instruct the base station to provide the PRS configuration to the UE via the LMF. Thus, a single NRPPa message completes the exchange of multiple pieces of information between the base station and the LMF, reducing the number of information exchanges and improving interaction efficiency. Alternatively, it can be an NRPPa PDU. When the LMF needs to send new or updated location assistance information to the base station for base station broadcasting, it sends the indication information via an NRPPa PDU. For example, the NRPPa message may include: the LMF requesting TRP information (TRP information request) from the base station. This NRPPa message can carry the indication information when sent to the base station.

[0129] In some embodiments, the indication information indicates one of the following;

[0130] The UE is permitted to send the on-demand PRS request;

[0131] or,

[0132] The UE is not allowed to send the on-demand PRS request.

[0133] This type of indication information is the first type of indication information, which can indicate whether the UE is allowed to send an on-demand PRS request.

[0134] In one embodiment, the indication information indicates one of the following:

[0135] When the UE obtains the PRS configuration, the UE is allowed to send the on-demand PRS request;

[0136] When the UE obtains the PRS configuration, the UE is not allowed to send the on-demand PRS request;

[0137] When the UE has not obtained the PRS configuration, the UE is allowed to send the on-demand PRS request;

[0138] When the UE has not obtained the PRS configuration, the UE is not allowed to send the on-demand PRS request.

[0139] This type of instruction information can be classified as the second type of instruction information.

[0140] The PRS configuration can be a predefined PRS configuration or any pre-obtained PRS configuration other than the predefined PRS configuration.

[0141] For example, the indication information indicates one of the following:

[0142] When the UE obtains the predefined PRS configuration, the UE is allowed to send the on-demand PRS request;

[0143] When the UE obtains the predefined PRS configuration, the UE is not allowed to send the on-demand PRS request;

[0144] When the UE has not obtained the predefined PRS configuration, the UE is allowed to send the on-demand PRS request;

[0145] When the UE has not obtained the predefined PRS configuration, the UE is not allowed to send the on-demand PRS request.

[0146] This indication information can be classified as a second type of indication information, which needs to be combined with the presence or absence of a predefined PRS configuration sent to the UE to indicate whether the UE is allowed to send the on-demand PRS request.

[0147] like Figure 5 As shown in the embodiments of this disclosure, an information processing method is also provided, which can be executed by an LMF. The method may include:

[0148] S410: Send area information, wherein the area information indicates the effective area range. The effective area range is the geographical range within which an indication message indicating whether the UE is allowed to send on-demand PRS requests is valid.

[0149] The instruction information may be the instruction information sent in step S310, or the instruction information sent by other network elements, or the instruction information agreed upon in the protocol.

[0150] In some embodiments, the region information includes one of the following:

[0151] Community Identifier ID;

[0152] Sending and receiving point ID;

[0153] System message SI area ID;

[0154] Access network notification area RNA ID.

[0155] A region information includes one or more cell IDs, and the cell IDs contained in the region information indicate the effective area range of the information.

[0156] A region information entry may include one or more Transmission Reception Point (TRP) IDs. The TRP ID included in the region information indicates the coverage area of ​​the TRP, which is the effective area range of the information.

[0157] The system message area ID is the effective area of ​​some system messages that span cells or block base stations. If the area indicated by the system message area ID included in the area information is the effective area range of the indicated information.

[0158] The RNA ID indicating the RNA can be a region of a paging RRC-inactive UE. In this embodiment of the disclosure, the RAN indicated by the RNA ID included in the region information is the effective range of the indication information.

[0159] like Figure 6 As shown, this disclosure provides an information processing method, which is executed by a base station. The method includes:

[0160] S510: Send indication information, wherein the indication information indicates whether the UE is allowed to send an on-demand PRS request.

[0161] The base station can be a gNB or an eNB.

[0162] The base station will send indication information to the UE, for example, by broadcasting, multicasting or unicasting the indication information.

[0163] This indication information indicates whether the UE is permitted to send an on-demand Position Reference Signal (PRS) request.

[0164] In this way, the base station can restrict whether the UE is allowed to send on-demand PRS requests by sending indication information, thereby reducing unnecessary transmissions by the UE when transmission is not allowed, and allowing the UE to request or provide suggestions for PRS configuration when flexible updates or configurations of PRS configuration are needed.

[0165] In some embodiments, S510 may include sending a system message containing the indication information to the UE.

[0166] The system message can be either MIB or SIBx, where x can be any positive integer, such as 1, 2, 3, or 7.

[0167] The instruction can be broadcast to all UEs in the cell via system messages, eliminating the need to send it to each UE individually.

[0168] In some embodiments, the indication information indicates one of the following;

[0169] The UE is permitted to send the on-demand PRS request;

[0170] or,

[0171] The UE is not allowed to send the on-demand PRS request.

[0172] This indication information alone can indicate whether the UE is allowed to send an on-demand PRS request, without the need for other information or conditions to restrict it.

[0173] In one embodiment, the indication information indicates one of the following:

[0174] When the UE obtains the PRS configuration, the UE is allowed to send the on-demand PRS request;

[0175] When the UE obtains the PRS configuration, the UE is not allowed to send the on-demand PRS request;

[0176] When the UE has not obtained the PRS configuration, the UE is allowed to send the on-demand PRS request;

[0177] When the UE has not obtained the PRS configuration, the UE is not allowed to send the on-demand PRS request.

[0178] For example, the indication information indicates one of the following:
