Description

Technical Field

[0001] This application relates to the field of wireless communication technology, and in particular to a service broadcasting method, apparatus, device, storage medium, and computer program product. Background Technology

[0002] With the widespread application of high-precision positioning technology in fields such as autonomous driving, intelligent transportation, and smart cities, the requirements for the real-time performance, accuracy, and efficiency of positioning technology are becoming increasingly stringent. In 5G systems, high-precision positioning services typically provide real-time dynamic carrier phase differential (RTK) data to terminals via broadcasting to improve positioning accuracy to the centimeter or even millimeter level.

[0003] In existing technologies, high-precision positioning services typically employ a static broadcast strategy based on the tracking area (TA) level. However, because existing broadcast strategies are statically configured at the TA level, they cannot be dynamically adjusted according to actual user service needs, lack the ability to perceive cell-level service demands, and struggle to achieve refined resource optimization goals. Furthermore, due to uneven user distribution and significant differences in service demand, using high-frequency broadcasting in areas with no or low demand will lead to a waste of air interface and core network signaling resources; while in high-demand areas, failure to increase broadcast frequency in a timely manner will fail to meet users' positioning service needs.

[0004] Therefore, there is an urgent need for a method that can dynamically adjust the high-precision positioning service broadcasting strategy according to the user's business needs. Summary of the Invention

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0018] This application provides a service broadcasting method to solve the problem that the existing technology adopts a static broadcasting strategy based on a fixed area, which cannot be dynamically adjusted according to the actual service needs of user equipment, resulting in low network resource utilization efficiency.

[0019] The execution subject of the service broadcasting method provided in this application embodiment may be, but is not limited to, at least one of a broadcast server, a communication server, and a network resource management server; in addition, the execution subject of the method may also be the system or application (APP) itself running on these servers.

[0020] For ease of description, the following description uses a service broadcasting system as the execution subject to illustrate the implementation of this method. It should be understood that using a service broadcasting system as the execution subject is merely an illustrative example and should not be construed as a limitation of the method.

[0021] In one implementation, the specific structure of the service broadcasting system provided in this application embodiment can be as follows: Figure 1 As shown, it mainly includes: User Equipment (UE), base station (gNodeB, gNB) and core network elements. Among them, the core network elements mainly include: Authentication Management Function (AMF) and Location Management Function (LMF).

[0022] Based on the above Figure 1 The service broadcasting system shown in this application is illustrated in the following schematic diagram, which illustrates the specific implementation process of the service broadcasting method provided in this application. Figure 2 As shown, the main steps include the following: Step 11: The base station obtains the high-precision positioning service requirement information sent by the user equipment (UE). In this embodiment of the application, the base station can obtain the high-precision positioning service request information sent by the user equipment (UE) in the following two ways: Method 1: Obtained through the random access procedure of an idle UE; When a UE in Radio Resource Control (RRC) idle state needs to transition to connected state due to high-precision positioning service requirements, the UE will initiate a random access procedure. In the MSG3 message of random access, the UE sends an RRCSetupRequest message to request the establishment of an RRC connection. In this invention, the EstablishmentCause field of this message has been extended, adding a new reason value to indicate the high-precision positioning service requirement, such as "MO-position".

[0023] Specifically, the base station receives and parses the RRCSetupRequest message, checking its EstablishmentCause field. If the value of the EstablishmentCause field is "MO-position", the base station determines that this random access is triggered by a high-precision positioning service request. The base station maintains a timer and a counter for each serving cell. Whenever an RRCSetupRequest message with an EstablishmentCause field value of "MO-position" is detected within the current period of the timer, the counter is incremented by 1. Within each period of the timer, the count value of this counter represents the service demand corresponding to the high-precision positioning service request information received from the UE within that time period.

[0024] Implementation 2: Obtain system information through a connected UE's system information request.

[0025] Specifically, when a UE in RRC connected state needs to obtain high-precision positioning data, it can trigger an on-demand system information request process. The UE sends an RRC System Info Request message, which carries a bitmap, such as a 32-bit "requested-posSI-List". Each bit in this bitmap corresponds to a high-precision positioning system information block type that can be broadcast. Based on the satellite system required for its current positioning and the list of available Position System Information Blocks (posSIBs) indicated by the network side in System Information Block Type 1 (SIB1) through posSI scheduling information, the UE sets the corresponding bit to '1' to make the request. After receiving this message, the base station parses the requested-posSI-List bitmap. If any bit in the bitmap is set to '1', it indicates that the connected UE has initiated a high-precision positioning service request. Similarly, the base station can maintain another counter within a preset statistical period to count the received valid requests of this type.

[0026] Step 12: The base station determines the broadcast strategy for high-precision positioning information of the target cell corresponding to the user equipment (UE) based on the high-precision positioning service requirement information obtained by executing step 11. In the embodiments of this application, the broadcast strategy may include a high-frequency broadcast mode, a low-frequency broadcast mode, or a silent mode.

[0027] Among them, high-frequency broadcast mode generally refers to broadcasting posSIB containing real-time kinematic (RTK) data over the air interface at a shorter period (such as once per second); low-frequency broadcast mode generally refers to broadcasting posSIB at a longer period (such as once every ten seconds); and silent mode generally refers to not broadcasting posSIB over the air interface.

[0028] In one implementation, the broadcast strategy can be determined by the following sub-steps, including: Sub-step 1201: The base station determines the total demand corresponding to the high-precision positioning service demand information obtained within a preset time period; Specifically, the base station can combine the demand information obtained by the two methods in step 11. Within the statistical period of the same timer, the base station can sum the number of requests obtained by method 1 and the number of requests obtained by method 2 as the total demand corresponding to the high-precision positioning service demand information received by the cell in the current statistical period.

[0029] Sub-step 1202: Based on the total demand and the preset first and second threshold values, determine the broadcast strategy for the high-precision positioning information of the target cell corresponding to the user equipment (UE).

[0030] In this embodiment of the application, the base station can pre-configure a first threshold Th based on network planning and resource capacity. low Second threshold Th high And satisfy Th high >Th low .

[0031] At the end of each statistical period, the base station can compare the total demand calculated for that period with the two thresholds mentioned above: If the total demand is lower than the first threshold Th low If so, the broadcast strategy is set to silent mode; If the total demand exceeds the first threshold Th low And below the second threshold Th high If so, the broadcast strategy is determined to be low-frequency broadcast mode; If the total demand exceeds the second threshold Th high If so, the broadcast strategy is determined to be high-frequency broadcast mode.

[0032] It should also be noted that, to avoid frequent mode switching due to instantaneous fluctuations in business volume, asymmetric switching conditions can be introduced in this embodiment. Let M be the threshold for the number of cycles in which the downgrade condition is continuously met, and N be the threshold for the number of cycles in which the upgrade condition is met. Generally, M > N can be set.

[0033] In this embodiment of the application, the specific mode switching judgment logic is as follows: Figure 3 As shown, when the base station determines, based on the above sub-steps 1201-1202, that it needs to upgrade from silent mode to low-frequency broadcast mode or from low-frequency broadcast mode to high-frequency broadcast mode, it can immediately increase the broadcast frequency as long as the total demand for one statistical period is higher than the threshold for reaching the corresponding target mode.

[0034] When the base station determines, based on the above sub-steps 1201-1202, that it needs to downgrade from high-frequency broadcast mode to low-frequency broadcast mode, or from low-frequency broadcast mode to silent mode, the base station will decide to reduce the broadcast frequency or enter silent mode only if the total demand in multiple consecutive statistical periods meets the downgrade conditions. This is to prevent service interruption due to a brief period of low business activity and ensure the stability of user experience.

[0035] Step 13: The base station broadcasts according to the broadcast strategy obtained by executing step 12 and sends broadcast feedback information to the core network elements; In this embodiment, the base station can schedule and broadcast the posSIB over the air interface of its serving cell according to the broadcast strategy obtained by executing step 12. It should be noted that in silent mode, although the base station does not broadcast, it still needs to process possible downlink data from the core network.

[0036] Meanwhile, in this embodiment of the application, the base station also needs to feed back its autonomously decided broadcast strategy to the core network control plane element AMF so that the AMF can perform collaborative optimization based on the broadcast strategy autonomously decided by the base station.

[0037] In one implementation, the uplink feedback is achieved through an extended definition of the Network Assistance Data Feedback message.

[0038] In this NetworkAssistance Data Feedback message, the base station not only reports failures but also adds a "rejection" response. Specifically, in the Criticism Diagnostics section of the NetworkAssistance Data Feedback message, when the feedback reason is "rejection," a new sub-reason value must be included.

[0039] Specifically, in the embodiments of this application, the following reason values ​​can be set, for example: The "No business requirements" reason value indicates that the base station has decided not to broadcast because there is no business demand in the current cell, i.e., the base station has chosen a silent mode. The "Low frequency business requirements" reason value indicates that the base station adopts low frequency broadcast mode due to low business demand.

[0040] By using the cause values ​​set above, the AMF can clearly understand why the base station did not perform according to its initial or default instructions.

[0041] Step 14: The core network element determines whether to encapsulate and send data related to the high-precision positioning service to the base station based on the received broadcast feedback information.

[0042] In the embodiments of this application, in the initial state, the core network element AMF can statically encapsulate RTK differential data from LMF for all base stations within its jurisdiction in a high-frequency mode, and send it through downlink non-UE associated NR positioning protocol A transmission (DOWNLINK NON UE ASSOCIATED NRPPA TRANSPORT) messages.

[0043] When the AMF receives the Network Assistance Data Feedback broadcast from the base station, it parses the broadcast feedback to obtain the cause value. Based on this cause value, it can determine why the base station did not execute its initial or default instructions, and then adjust the transmission strategy accordingly. Specifically, this may include: If, within X consecutive feedback cycles (e.g., X=3), the broadcast feedback information received from the base station corresponding to cell A carries the reason value "No business requirements," the AMF can determine that the cell has no long-term demand for high-precision positioning services. Consequently, in subsequent cycles, the AMF will no longer include cell B in the target list for RTK data encapsulation and distribution, i.e., it will stop sending Assistance Information Control messages to it, thereby saving signaling resources between the core network and the radio network.

[0044] If, within X consecutive feedback cycles, the broadcast feedback information received from the base station corresponding to cell B all carries the cause value of "Low frequency business requirements", then the AMF can record the cell status, but still encapsulate and send data to it at a lower priority or frequency to adapt to its low-frequency broadcast rhythm.

[0045] It should also be noted that, to ensure a rapid response when demand suddenly surges, in this embodiment, the AMF can also monitor service request messages on the N1 interface. If a large number of requests with "MO-position" EstablishmentCause originate from a certain cell, and the number of such requests reaches a preset threshold within the statistical period, the AMF will ignore all previous low-frequency or silent feedback from that cell and immediately force the encapsulation and distribution of RTK data to that cell in high-frequency mode, thereby ensuring rapid service recovery.

[0046] In one implementation, based on the service broadcasting method provided in this application, the interaction flow between modules in the service broadcasting system is as follows: Figure 4 As shown, the main processes include the following: In process 1, during the initial or silent period, the base station gNB does not actively broadcast high-precision positioning RTK information, but in its system information block SIB1, it will announce to all UEs that the cell has the ability to provide broadcast high-precision positioning services through specific indication information (image).

[0047] Process 2: Business Requirement Awareness and Reporting; Specifically, base stations can sense the high-precision positioning service requirements of UEs through two paths: Path 1, Idle UE request reporting: Specifically, if a UE in idle state needs to initiate a service due to high-precision positioning requirements, it can send an RRC Setup Request message in the MSG3 of random access. The Establishment Cause in this RRC Setup Request message includes an MO-position value to explicitly identify that the connection establishment was triggered by the high-precision positioning service.

[0048] Path 2, UE request reporting in connected state: Specifically, when a UE that is already in a connected state needs high-precision positioning data, it actively sends an RRC System InfoRequest message to request a specific high-precision positioning system information block (posSIB) in an on-demand manner.

[0049] Step 3, Base Station Side Policy Decision-Making and Execution: The gNB maintains a demand statistics timer to periodically summarize the number of demands reported through the two methods mentioned above, thus obtaining the total number of business demands.

[0050] The system dynamically determines the air interface broadcasting strategy for this cell by comparing the total demand with preset thresholds 1 and 2: if the demand is extremely low, a silent mode is selected; if the demand is moderate, a low-frequency broadcasting mode is selected; and if the demand is high, a high-frequency broadcasting mode is selected.

[0051] Step 4: The base station feeds back the strategy to the core network; gNB feeds back the results and reasons for its autonomous decisions to AMF via Network Assistance Data Feedback messages.

[0052] Specifically, a reason value for "rejecting" broadcasting has been added to the feedback message. For example, "No business requirements" or "Low frequency business requirements." This feedback message then informs the AMF that the gNB's failure to broadcast is not due to a fault, but rather a proactive policy adjustment based on business awareness.

[0053] Step 5: Dynamically adjust the encapsulation and distribution strategy on the core network side; After receiving feedback from the gNB, the AMF decides whether to send RTK information to different cells based on the rejection feedback value from the gNB.

[0054] Specifically, if a cell receives a "no demand" feedback for several consecutive cycles, the AMF can stop encapsulating and sending RTK data to that gNB in ​​subsequent cycles and stop sending DOWNLINK NON UE ASSOCIATED NRPPA TRANSPORT messages, thereby saving transmission resources and signaling load.

[0055] In one implementation, the AMF simultaneously counts Service Request messages on the N1 port based on a timer. If, within a short period, there is a surge in requests from a certain area carrying MO-position reasons, the AMF will disregard previous low-frequency / silent feedback from that cell and immediately force a resumption of high-frequency RTK data transmission to that cell, ensuring service capacity during sudden service peaks. In one implementation, the specific processing flow of the above service broadcast method is as follows: Figure 5 As shown.

[0056] Step 6: Data source and regular distribution path; LMF obtains RTCM differential data from the CORS platform and encapsulates it into auxiliary information.

[0057] AMF transmits the assistance information provided by LMF to gNB via the DOWNLINK NON UE ASSOCIATED NRPPA TRANSPORT message.

[0058] Using the service broadcasting method provided in this application embodiment, before broadcasting the service, the base station can obtain high-precision positioning service request information sent by the user equipment (UE). Based on the obtained high-precision positioning service request information, the base station determines a broadcasting strategy for the high-precision positioning information of the target cell corresponding to the UE. Then, the base station broadcasts according to the broadcasting strategy and sends broadcast feedback information to the core network element, so that the core network element determines whether to encapsulate and send data related to the high-precision positioning service to the base station based on the received broadcast feedback information. The service broadcasting method provided in this application has the following advantages: First, the base station actively senses and counts the high-precision positioning service demands from the UE, and dynamically decides which mode to broadcast based on the service demands in real time. This achieves a precise match between the broadcasting strategy and the actual service demands. In areas with low or no service demands, the base station can adopt low-frequency broadcasting or a silent mode, avoiding the ineffective occupation of air interface broadcast channel resources caused by uniform high-frequency broadcasting according to static TA areas in the prior art. Second, the base station can feed back its own broadcasting strategy to the core network element, so that the core network element can decide whether to encapsulate and send high-precision positioning data to the base station based on the received broadcasting strategy. This avoids ineffective data push to base stations with no or low broadcasting demands, reducing the signaling transmission load between the core network and the radio access network and the data processing pressure within the core network.

[0059] In one embodiment, this application also provides a service broadcasting device to address the problem that existing technologies employ static broadcasting strategies based on fixed areas, which cannot dynamically adjust according to the actual service needs of user equipment, resulting in low network resource utilization efficiency. A schematic diagram of the specific structure of this service broadcasting device is shown below. Figure 6 As shown, it includes: a business requirement acquisition unit 61, a broadcast strategy determination unit 62, and a broadcast unit 63.

[0060] Among them, the service requirement acquisition unit 61 is used to acquire high-precision positioning service requirement information sent by the user equipment (UE). The broadcast strategy determination unit 62 is used to determine a broadcast strategy for the high-precision positioning information of the target cell corresponding to the user equipment UE based on the high-precision positioning service requirement information, wherein the broadcast strategy includes a high-frequency broadcast mode, a low-frequency broadcast mode, or a silent mode. The broadcast unit 63 is used to broadcast according to the broadcast strategy and send broadcast feedback information to the core network element, so that the core network element can determine whether to encapsulate and send data related to the high-precision positioning service to the base station based on the received broadcast feedback information; wherein, the broadcast feedback information is used to indicate the broadcast strategy determined by the base station.

[0061] In one embodiment, the service requirement acquisition unit 61 is specifically configured to: receive an RRC connection establishment request message sent by the user equipment (UE) in an idle state during a random access process, wherein the RRC connection establishment request message carries an establishment reason value for indicating a high-precision positioning service requirement.

[0062] In one embodiment, the service requirement acquisition unit 61 is specifically configured to: receive a system information request message sent by a UE in a connected state, wherein the system information request message includes bitmap information for requesting a high-precision positioning system information block; and determine the high-precision positioning service requirement information of the user equipment UE based on the bitmap information.

[0063] In one embodiment, the broadcast strategy determination unit 62 is specifically used to: determine the total demand corresponding to the high-precision positioning service demand information obtained within a preset time period; and determine a broadcast strategy for the high-precision positioning information of the target cell corresponding to the user equipment UE based on the total demand and a preset first threshold and a second threshold, wherein the second threshold is higher than the first threshold.

[0064] In one implementation, the broadcast strategy determination unit 62 is specifically configured to: determine the broadcast strategy as a silent mode when the total demand is lower than the first threshold; determine the broadcast strategy as a low-frequency broadcast mode when the total demand is higher than the first threshold and lower than the second threshold; and determine the broadcast strategy as a high-frequency broadcast mode when the total demand is higher than the second threshold.

[0065] In one implementation, the broadcast feedback information carries a reason value indicating that the base station did not broadcast as instructed by the core network element. The reason value indicates the reason why the base station did not perform the broadcast as instructed by the core network element.

[0066] Using the service broadcasting apparatus provided in this application embodiment, before broadcasting a service, the base station can obtain high-precision positioning service request information sent by the user equipment (UE). Based on the obtained high-precision positioning service request information, the base station determines a broadcasting strategy for the high-precision positioning information of the target cell corresponding to the UE. Then, the base station broadcasts according to the broadcasting strategy and sends broadcast feedback information to the core network element, so that the core network element determines whether to encapsulate and send data related to the high-precision positioning service to the base station based on the received broadcast feedback information. The service broadcasting apparatus provided in this application has the following advantages: First, the base station actively senses and counts the high-precision positioning service demands from the UE, and dynamically decides which mode to broadcast based on the service demands in real time. This achieves a precise match between the broadcasting strategy and the actual service demands. In areas with low or no service demands, the base station can adopt low-frequency broadcasting or a silent mode, avoiding the ineffective occupation of air interface broadcast channel resources caused by uniform high-frequency broadcasting according to static TA areas in the prior art. Second, the base station can feed back its own broadcasting strategy to the core network element, so that the core network element can decide whether to encapsulate and send high-precision positioning data to the base station based on the received broadcasting strategy. This avoids ineffective data push to base stations with no or low broadcasting demands, reducing the signaling transmission load between the core network and the radio access network and the data processing pressure within the core network.
