[0002] Currently, the single-point positioning accuracy of the GPS satellite positioning system is 20-40 meters. The positioning accuracy of the Beidou positioning system is also at a similar level. However, this level of accuracy is insufficient for many applications (such as aircraft landing, ship arrival, and vehicle-to-vehicle scheduling), and it is difficult to meet user needs.

[0003] Recently, the industry has proposed using GPS / Beidou differential positioning methods to improve positioning accuracy. In some scenarios, positioning accuracy can reach the meter or even centimeter level. There are three common differential positioning methods: wide-area differential, single-station differential, and regional differential.

[0097] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0098] like Figure 1 As shown, an embodiment of the present invention provides a positioning service processing method, which is executed by a core network element, including:

[0099] Step 101, configuring a location system information block posSIB broadcasting strategy of a base station;

[0100] Step 102: Send the posSIB broadcasting strategy to the corresponding base station.

[0101] In the embodiment of the present invention, the core network element is provided with a location service broadcast module, which is responsible for formulating and sending posSIB broadcast strategies.

[0102] As an optional embodiment, the posSIB advertisement strategy includes at least one of the following:

[0103] Apply to the core network for posSIB for broadcast content, broadcast time, broadcast area, broadcast cycle, broadcast method, and base station support.

[0104] Optionally, for different base stations, the corresponding posSIB broadcasting strategies may be different or the same, which is not specifically limited here. As shown in Table 1, the posSIB broadcasting strategies include:

[0105]

[0106]

[0107] Table 1

[0108] As an optional embodiment, step 102 includes:

[0109] The posSIB broadcasting strategy is sent to the corresponding base station via the new radio positioning protocol NRPPa.

[0110] In at least one embodiment of the present invention, the method further comprises:

[0111] The SIB broadcast area (SIA) or tracking area update TAU area is matched with the broadcast area of ​​the reference station in terms of physical area.

[0112] The SIB broadcast area can be understood as the SIB can be reused within an area. When the UE moves within the area and finds that the valueTag of the SIB has not changed, there is no need to read the SIB again. Matching with the SIB broadcast area can reduce the terminal power consumption problem caused by the user equipment repeatedly obtaining system information.

[0113] Optionally, physically matching the SIB broadcast area or tracking area update TAU area with the broadcast area of ​​the reference station includes:

[0114] Sending the correspondence between the SIB broadcast area and the broadcast area of ​​the reference station to the network management platform, and the network management platform configuring the SIB broadcast area based on the correspondence;

[0115] or,

[0116] Sending the correspondence between the TAU area and the broadcast area of ​​the reference station to the network management platform, and the network management platform configuring the TAU area based on the correspondence;

[0117] or,

[0118] Obtain configuration information of the SIB broadcast area of ​​the network management platform, and reconfigure the SIB broadcast area according to the configuration information and the broadcast area of ​​the reference station;

[0119] or,

[0120] The configuration information of the TAU area of ​​the network management platform is obtained, and the TAU area is reconfigured according to the configuration information and the broadcast area of ​​the reference station.

[0121] In other words, matching the SIB broadcast area can be implemented in at least two ways: one is for the location service broadcast module to send the broadcast area correspondence to the SIB broadcast area configuration platform (network management platform), which then configures the SIB broadcast area based on the area matching relationship; the other is for the location service broadcast module to read the configuration information from the SIB broadcast area configuration platform and reconfigure the SIB broadcast area based on this information. The TAU area (core network) can adopt the same strategy.

[0122] For example, the broadcast area of ​​a base station can correspond to 3.5 SIAs (SIB broadcast areas) through physical area matching. If one of the SIAs belongs to a different base station, the terminal will need to read the broadcast message twice in this SIA. Therefore, it is recommended to consider the correspondence between the two when dividing the areas. SIAs belonging to two broadcast areas can be assigned to one broadcast area or the SIAs can be re-divided according to the broadcast areas to achieve matching between the two.

[0123] In summary, in the embodiment of the present invention, the core network element formulates the posSIB broadcasting strategy and notifies the base station, so that the posSIB broadcasting strategy is more detailed and the posSIB broadcasting efficiency is improved.

[0124] like Figure 2 As shown, an embodiment of the present invention further provides a positioning service processing method, which is executed by a base station and includes:

[0125] Step 201: receiving a position system information block posSIB broadcasting strategy configured and sent by a core network element;

[0126] Step 202: Transmit the posSIB advertising strategy to the user equipment.

[0127] In the embodiment of the present invention, the core network element is provided with a location service broadcast module, which is responsible for formulating and sending posSIB broadcast strategies.

[0128] As an optional embodiment, the posSIB advertisement strategy includes at least one of the following:

[0129] Apply to the core network for posSIB for broadcast content, broadcast time, broadcast area, broadcast cycle, broadcast method, and base station support.

[0130] Optionally, for different base stations, the corresponding posSIB broadcasting strategies may be different or the same, which is not specifically limited here.

[0131] In at least one embodiment of the present invention, step 202 includes:

[0132] Transmitting the partial posSIB broadcasting strategy to the user equipment through at least one of the user registration procedure, the system information block SIB 1 and the tracking area update TAU procedure;

[0133] and / or,

[0134] Part of the posSIB advertising strategy is transmitted to the user equipment through user subscription information and / or user plane data packets.

[0135] For example, information such as the broadcast area and broadcast time in the posSIB broadcast policy can be notified to the user equipment through user subscription information, user plane data packets, etc., while other content in the posSIB broadcast policy can be notified to the user equipment through the user registration process or SIB 1 or TAU process.

[0136] Optionally, the above-mentioned user subscription information and / or user plane data packet may further include priority information of a method for acquiring location services, etc., which is not specifically limited here.

[0137] In at least one embodiment of the present invention, the location service broadcast method includes: a control plane broadcast method, i.e., broadcasting based on the control plane. User equipment can obtain satellite differential information based on periodic broadcasts or on-demand requests, thereby calculating accurate location information. The LMF can broadcast network assistance information via the NRPPa protocol, and the user equipment can obtain the key via a registration request message. For this control plane broadcast method, the method further includes:

[0138] Upon receiving a posSIB request message from a user equipment, if there is no posSIB information corresponding to the posSIB request message, a service request message is sent to a core network element, the service request message being used to request the core network element to send the posSIB information. Optionally, the service request message includes at least information such as the posSIB type.

[0139] For example, when the user selects the control plane broadcast scheme, after the base station receives the user's broadcast PosSIB request, it first determines whether it has the corresponding PosSIB information from the core network. If so, it starts broadcasting. If not, it makes a request to the LMF. If the request is successful, it broadcasts to the terminal. If the request fails, it replies to the terminal that it cannot broadcast.

[0140] Optionally, after receiving the indication that the network cannot broadcast, the user starts the user plane application process or the user requests the high-precision platform to send PosSIB information to the base station side.

[0141] In the embodiment of the present invention, the core network element formulates the posSIB broadcast strategy and notifies the base station. The base station transmits the posSIB broadcast strategy to the user equipment in various ways, making the posSIB broadcast strategy more detailed and improving the posSIB broadcast efficiency. The control plane broadcast process is optimized, and a process for the base station to apply for broadcasting posSIB information is added, which supplements the shortcomings of the existing process.

[0142] like Figure 3 As shown, an embodiment of the present invention further provides a positioning service processing method, which is executed by a user equipment, including:

[0143] Step 301: obtaining the posSIB broadcasting strategy transmitted by the base station;

[0144] Step 302: Determine a location service acquisition method based on the posSIB broadcast strategy, the user equipment's location information, the user equipment's subscription information, and the current time information; the acquisition method includes at least one of an application-side broadcast method, a user-plane broadcast method, and a control-plane broadcast method.

[0145] The application-side broadcasting method can be understood as: establishing a communication link between the application side and the terminal to transmit "positioning differential information";

[0146] The user plane broadcast method can be understood as: point-to-point broadcast between the user equipment and the LMF through the LPP or SUPL user plane protocol; for example, relevant positioning information and enhancement information are all transmitted through the non-access stratum (NAS) signaling by the user equipment to the base station and then to the mobility management entity MME, and then forwarded to the evolved serving mobile positioning center E-SMLC.

[0147] The control plane broadcast method can be understood as follows: based on the broadcast broadcast of the control plane, the user device can obtain satellite differential information based on periodic broadcasts or on-demand requests, and then calculate accurate position information. LMF can broadcast network assistance information through the NRPPa protocol, and the user device can obtain the secret key through the registration request message.

[0148] As an optional embodiment, the posSIB advertisement strategy includes at least one of the following:

[0149] Apply to the core network for posSIB for broadcast content, broadcast time, broadcast area, broadcast cycle, broadcast method, and base station support.

[0150] Optionally, for different base stations, the corresponding posSIB broadcasting strategies may be different or the same, which is not specifically limited here.

[0151] In at least one embodiment of the present invention, step 301 includes:

[0152] Obtaining a partial posSIB broadcasting strategy transmitted by the base station through at least one of a user registration process, a system information block SIB 1, and a tracking area update TAU process;

[0153] and / or,

[0154] Obtain part of the posSIB advertising strategy through user subscription information and / or user plane data packets.

[0155] For example, information such as the broadcast area and broadcast time in the posSIB broadcast policy can be notified to the user equipment through user subscription information, user plane data packets, etc., while other content in the posSIB broadcast policy can be notified to the user equipment through the user registration process or SIB 1 or TAU process.

[0156] Optionally, the above-mentioned user subscription information and / or user plane data packet may further include priority information of a method for acquiring location services, etc., which is not specifically limited here.

[0157] In at least one embodiment of the present invention, step 302 includes:

[0158] Determining first information based on at least one of the posSIB broadcasting policy, location information of the user equipment, subscription information of the user equipment, and current time information, the first information including at least one of the following: whether the user equipment supports the LTE Positioning Protocol (LPP) or the Secure User Plane Positioning Protocol (SUPL); whether the base station to which the user equipment belongs supports control plane broadcasting at the current time; whether the base station to which the user equipment belongs supports applying for the posSIB from the core network; and a priority of a method for obtaining a location service subscribed by the user;

[0159] Determine a method for acquiring location services based on the first information.

[0160] If the user does not support LPP or SUPL protocols, he can only choose the application side broadcast method or the control plane broadcast method. If the user contract information or posSIB broadcast strategy shows that the current base station does not support control plane broadcast in the current period and does not support application to LMF, the user can only choose user plane broadcast. In other cases, the user can choose either user plane or control plane, depending on the priority of the user's contract acquisition method or the user's own choice.

[0161] like Figure 4 As shown, the user equipment starts location service acquisition. If the contract information indicates that control plane broadcast is not supported and the user does not support LPP or SUPL protocols, the user equipment selects the application side broadcast mode; if the contract information indicates that control plane broadcast is supported, the user equipment selects the control plane broadcast mode; if the user supports LPP or SUPL protocols, the user equipment selects the user plane broadcast mode or the application side broadcast mode. If the user has signed a user plane priority contract, the user plane broadcast mode is selected; if the contract information indicates that control plane broadcast is supported but the user does not support LPP or SUPL protocols, the user selects the application side broadcast mode.

[0162] In summary, in the embodiment of the present invention, the core network element formulates the posSIB broadcasting strategy and notifies the base station, and the base station notifies the user equipment of the posSIB broadcasting strategy. The user equipment determines the acquisition method of the location service based on the posSIB broadcasting strategy, its own location information, subscription information, and current time information, so that the user can obtain high-precision differential positioning information more quickly.
