Description

Technical Field

[0001] The present application relates to the field of communications, and more specifically, to a system information processing method, a terminal device, and a network device. Background Art

[0002] In the New Radio (NR) system, System Information (SI) includes minimum SI and other SI. Minimum SI includes the periodically broadcast MIB and SIB1, and other SI includes system information other than MIB and SIB1, such as SIB2, SIB3, etc. The issuance of other SI can be triggered by the network or by the terminal device UE, which is called on-demand SI. Based on this, the network can indicate in SIB1 whether the UE periodically broadcasts certain SIB information. For SIBs that the network does not periodically broadcast, the UE can obtain the required SI by initiating an SI request to the network. The introduction of on-demand SI can save power consumption on the network side and the signaling overhead caused by periodic broadcasts. For UEs in idle or inactive states, SI requests can be completed through the random access process, including SI requests based on Msg1 and SI requests based on Msg3. After the random access is successfully completed, the UE listens to the network broadcast information to obtain the required SI. For a UE in a connected state (CONNECTED), the UE may request the required SI from the network by carrying specific parameter information in uplink transmission.

[0003] However, if the UE's SI request to the network fails to be successfully transmitted, for example, the UE's random access process fails, the SI request cannot reach the network, and the network cannot accurately and effectively count the SI information required by the UE in the current cell. The network will adjust the sending of SI from UE request to periodic broadcast, which will increase the signaling overhead of periodic broadcast on the network side and increase power consumption.

Wearable devices may also be called wearable smart devices, which are a general term for wearable devices that are intelligently designed and developed using wearable technology for daily wear, such as glasses, gloves, watches, clothing, and shoes. A wearable device is a portable device that is worn directly on the body or integrated into the user's clothes or accessories. Wearable devices are not only hardware devices, but also achieve powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include those that are fully functional, large in size, and can achieve complete or partial functions without relying on smartphones, such as smart watches or smart glasses, as well as those that only focus on a certain type of application function and need to be used in conjunction with other devices such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.

[0046] It should be understood that the terms "system" and "network" are often used interchangeably herein. The term "and / or" is used herein to describe an association relationship between associated objects. For example, it indicates that three possible relationships exist between the associated objects. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. The character " / " generally indicates that the associated objects exist in an "or" relationship.

[0047] In the description of the embodiments of the present application, the term "corresponding" may indicate a direct or indirect correspondence between the two, or an association relationship between the two, or a relationship between indication and being indicated, configuration and being configured, etc.

[0048] The embodiments of the present application provide a system information processing, a terminal device, and a network device. To clearly illustrate the concept of the embodiments of the present application, a process of minimizing drive tests (MDT) in a communication system is first briefly described.

[0049] Minimization of Drive Tests (MDT) technology primarily uses measurement reports from terminals to obtain relevant parameters for network optimization. MDT reduces drive test overhead, shortens optimization cycles, and lowers network maintenance and optimization costs. It also collects measurement information from areas not covered by traditional drive tests, such as narrow roads, forests, and private locations. MDT facilitates accurate assessment of network performance.

[0050] MDT supports both Immediate MDT and Logged MDT modes. Immediate MDT requires the UE to perform measurements in a connected state and report the measurement report to the network after the measurement is completed. Logged MDT requires the UE to perform and store measurements in the IDLE or INACTIVE state based on configuration parameters, and report the measurement results to the network upon network request after entering the connected state.

[0051] Immediate MDT and Logged MDT activation supports two methods: management-based and signaling-based. Before activating MDT, users need to submit consent information to the core network. For management-based MDT, the core network sends the user consent information to the wireless access network (RAN), and the RAN instructs UEs in the area to activate MDT. For signaling-based MDT, the core network instructs specific UEs to activate MDT without sending the user consent information to the RAN.

[0052] refer to Figure 2 , an embodiment of the present application provides a system information processing method, applied to a terminal device, the method comprising:

[0053] S101, when the terminal device is in an idle state or an inactive state, if a first condition is met, the terminal device records relevant information of the system information request; and / or, when the terminal device is in a connected state, if a second condition is met, the terminal device records relevant information of the system information request.

[0054] According to an embodiment of the present application, when predetermined conditions are met, the terminal device will be triggered to record relevant information of the system information request (SIrequest), which can be used to report to the network at an appropriate time, helping the network to accurately and effectively count the SI required by the terminal and optimize the configuration of system information.

[0055] Optionally, the relevant information of the system information request includes at least one of the following information: the requested system information type, the current working bandwidth part BWP, random access resource information, the random access process type, the system information request based on the first message Msg1, the system information request based on the third message Msg3, and the system information requirement list corresponding to the historical resident cells of the terminal device.

[0056] Correspondingly, refer to Figure 3 , an embodiment of the present application further provides a system information processing method, applied to a network device, the method comprising:

[0057] S201, a network device receives relevant information of a system information request recorded by a terminal device; wherein, the relevant information of the system information request is recorded by the terminal device in an idle state or an inactive state when a first condition is met, and / or, the relevant information of the system information request is recorded by the terminal device in a connected state when a second condition is met.

[0058] According to an embodiment of the present application, the network device can receive relevant information of the system information request recorded by the terminal device. Based on the relevant information of the system information request, the network device can optimize the configuration of the system information. For example, for the system information requested by the terminal, the network device can issue SI according to the request. For the sending of other system information, the network device can be set to periodic broadcast to reduce unnecessary signaling overhead and power consumption.

[0059] Optionally, the first condition includes at least one of the following situations:

[0060] ① The number of random access attempts initiated by the terminal device for requesting system information reaches the maximum number of attempts for the random access procedure for requesting system information;

[0061] ② The number of consecutive unsuccessful random access procedures for requesting system information by the terminal device reaches the maximum number configured by the network device;

[0062] ③ The number of times the terminal device sends system information requests to the network device reaches the maximum number configured by the network device for the terminal device;

[0063] ④ Cell reselection occurs before the network device initiates the random access procedure for requesting system information;

[0064] ⑤ When a cell reselection occurs during a random access process performed by a network device for requesting system information, the terminal device enters an idle state;

[0065] ⑥ The terminal device detects the first system information in the system broadcast without requesting the first system information.

[0066] Optionally, the second condition includes at least one of the following situations:

[0067] ① The terminal device successfully accesses the cell;

[0068] ② The system information required by the terminal device changes;

[0069] ③ The number of times the terminal device sends system information requests to the network device reaches the maximum number configured by the network device for the terminal device;

[0070] ④ The process of the terminal device sending a system information request to the network device fails to complete successfully, for example, a radio link failure (RLF) or handover occurs during the process of the terminal device requesting system information;

[0071] ⑤ The terminal device detects the first system information in the system broadcast without requesting the first system information.

[0072] Regarding the first and second conditions above, they can be regarded as trigger conditions for UEs in different states to record SI request related information. When any of the above conditions is met, that is, the corresponding trigger conditions are met, the UE can be triggered to start recording SI request related information.

[0073] Optionally, the terminal device may report relevant information of the recorded system information request to the network device based on a logged minimization of drive tests (Logged MDT) mode.

[0074] Optionally, the terminal device may report relevant information of the recorded system information request to the network device based on an Immediate Minimization of Drive Test (Immediate MDT) mode.

[0075] Optionally, the terminal device may report relevant information of the recorded system information request to the network device based on the Logged MDT mode and the Immediate MDT mode.

[0076] Optionally, the terminal device receives first indication information from a network device, where the first indication information is used to instruct the terminal device to record relevant information of the system information request.

[0077] Optionally, the terminal device receives second indication information from the network device, where the second indication information is used to instruct the terminal device to report relevant information of the system information request.

[0078] Optionally, the terminal device may determine to record relevant information of the system information request according to high-level configuration or pre-configuration information.

[0079] Optionally, the terminal device may determine, based on high-level configuration or pre-configuration information, to report relevant information of the system information request to the network device.

[0080] By utilizing at least one of the above embodiments of the present application, those SI requests that fail to be successfully transmitted through the random access process can also be recorded in whole or in part for reporting to the network, thereby avoiding the network adjusting the sending of this part of the SI from request-based sending to broadcast sending, thereby avoiding unnecessary signaling overhead and power consumption.

[0081] The above describes the implementation of the system information processing method of the embodiment of the present application through embodiments. The following describes the specific implementation process of the embodiment of the present application through multiple specific examples.

[0082] Example 1

[0083] In this embodiment, the UE is in an idle state or an inactive state, and when the UE reaches the maximum number of random access attempts, the UE records the relevant information of the SI request. The following provides a variety of different specific implementations that can be used, all of which can implement the system information processing method of the embodiment of the present application.

[0084] First, when the UE is in the RRC_IDLE state or the RRC_INACTIVE state, the UE may determine the maximum number of random access attempts according to the network configuration, for example, the maximum number of attempts is N. The UE may obtain the current system information broadcast status according to specific parameters in the SIB1, such as si-SchedulingConfig, based on which the UE may determine whether it needs to request SI.

[0085] Then, refer to Figure 4, the UE initiates a random access procedure for system information request, that is, initiates a system information request procedure based on Msg1 or Msg3, and this procedure may need to be attempted multiple times. If the UE still does not receive an access success indication from the network after initiating the Nth random access attempt, that is, the number of random access attempts initiated by the UE for requesting SI has reached the maximum number of attempts configured by the network, then one of the triggering conditions given above is met, triggering the UE to record relevant information of the current system information request, for example: the UE records at least one of the following information: the requested system information type, the current working bandwidth part BWP, random access resource information, the random access procedure type (for example, SI request based on Msg1, or SI request based on Msg3), etc.

[0086] Among them, if the UE reselects a cell before initiating the random access process for the SI request, or if the UE reselects a cell during the random access process for the SI request and the UE enters the IDLE state, these two situations respectively meet the two trigger conditions described above, then the UE is triggered to record the relevant information of the current system information request.

[0087] In addition, if the UE can obtain the required SIB information other than SIB1 from the system broadcast without initiating the SI request process (for example, the UE needs SIB3, and SIB3 is included in the current system broadcast), then one of the trigger conditions given above is met, and the UE records the relevant SIB information type (for example, SIB3). Afterwards, when the network receives the SI request related information reported by the UE, it can adjust SIB3, for example, to an on-demand SI request, and adjust the sending of SIB3 to be sent according to the SI request instead of being sent through broadcast, thereby saving system signaling overhead.

[0088] Example 2

[0089] In this embodiment, the UE is in an idle state or an inactive state, and when the UE reaches the maximum number of SI requests, the UE records the relevant information of the SI request. The following provides a variety of different specific implementations that can be used, all of which can implement the system information processing method of the embodiment of the present application.

[0090] First, when the UE is in the RRC_IDLE state or the RRC_INACTIVE state, the network configures the parameters for the UE to trigger the recording of SI request related information, including the maximum number of consecutive unsuccessful random access procedures M, where the random access procedure is used to request SI, and the maximum number of attempts for each random access procedure is N. The UE can obtain the current system information broadcast status based on the parameter si-SchedulingConfig in SIB1, based on which the UE can determine whether it needs to request SI;

[0091] Then, refer to Figure 5 , the UE initiates a system information request process based on Msg1 or Msg3. If the UE does not receive an access success indication from the network after initiating the Nth random access attempt, the UE considers that the current random access process has not been successfully completed and will initiate the random access process again. If the UE does not receive an access success indication from the network for M consecutive times and the UE does not detect the required system information in the system broadcast, the UE records information related to the current system information request, such as the requested system information type, random access resource information, random access process type (such as SI request based on Msg1, or SI request based on Msg3), etc.

[0092] If, before the UE initiates the Kth (K≤M) random access procedure for SI request, a cell reselection occurs or a required system message is detected in the system broadcast, the UE records information related to the current system information request.

[0093] If the UE reselects a cell during the Rth (R≤M) random access process for SI request, the UE enters the IDLE state, and the UE records information related to the current system information request.

[0094] In addition, if the UE can obtain the required SIB information other than SIB1 from the system broadcast without initiating the SI request process (for example, the UE needs SIB2, and SIB2 is included in the current system broadcast), the UE records the relevant SIB information type (for example, SIB2).

[0095] Example 3

[0096] In this embodiment, the UE is in a connected state. The following provides a variety of different specific implementation methods that can be adopted, all of which can implement the system information processing method of the embodiment of the present application.

[0097] For a UE in the RRC_CONNECTED state, the UE may be triggered to record relevant information of the SI request when at least one of the following conditions is met.

[0098] Case 1:

[0099] When a UE successfully accesses a cell, the UE records the SI list of interest in the current cell.

[0100] Optionally, when the SI required by the UE changes, the UE may be triggered to record the relevant information of the SI. For example, refer to Figure 6 If the SI of interest to a UE in an RRC connected state changes at different times, the UE records the SI list at each time.

[0101] Case 2:

[0102] The network configures a maximum number L for the UE to send SI requests. When the number of times the UE sends SI requests reaches the maximum number L, the UE records information related to the SI request.

[0103] For example, reference Figure 7 , the UE can request the required SI by carrying parameters (such as the parameter DedicatedSIBRequest) in the uplink transmission resources. If the UE still does not receive confirmation feedback from the network after the Lth transmission, the UE records the relevant information of the SI request.

[0104] Case 3:

[0105] If the UE fails to successfully complete the SI request, for example, RLF or handover occurs during the SI request process, the UE records information related to the SI request.

[0106] Case 4:

[0107] If the UE can obtain the required SIB information other than SIB1 from the system broadcast without initiating the SI request process (for example, the UE needs SIB3, and SIB3 is included in the current system broadcast), the UE records the relevant SIB information type (for example, SIB3).

[0108] After recording the relevant information of the system information request, the UE may report the recorded information to the network. In an embodiment of the present application, the UE may report the SI request related information to the network based on the Logged MDT and / or Immediate MDT framework.

[0109] For example, in the Logged MDT mode, the UE performs measurements in the IDLE state or INACTIVE state, and reports the measurement results to the network after entering the connected state. At this time, the recorded SI request-related information can be reported to the network together with the measurement results.

[0110] For another example, in the Immediate MDT mode, the UE performs measurements in the connected state and reports to the network after the measurements are completed. In this case, the recorded SI request-related information is reported to the network together with the measurement results.

[0111] Optionally, the reported SI request information may also include a SI requirement list of cells where the UE has historically camped (recording the physical cell identity (PCI) of the corresponding cell), so that the network can adjust the system information configuration regionally according to the reported information.

[0112] It should be noted that, optionally, the UE of an embodiment of the present application can determine the relevant information for processing the SI request in accordance with at least one of the above embodiments based on high-level configuration or pre-configuration information; optionally, the UE of an embodiment of the present application can also determine the relevant information for processing the SI request in accordance with at least one of the above embodiments based on the instructions of the network device.

[0113] The above describes the specific configuration and implementation of the embodiment of the present application from different perspectives through multiple embodiments. Corresponding to the processing method of at least one of the above embodiments, the embodiment of the present application also provides a terminal device 100, referring to Figure 8 , which includes:

[0114] The recording module 110 is used to record relevant information of the system information request when the terminal device is in an idle state or an inactive state and meets the first condition; and / or, to record relevant information of the system information request when the terminal device is in a connected state and meets the second condition.

[0116] The number of random access attempts initiated by the terminal device for requesting system information reaches the maximum number of attempts for the random access procedure for requesting system information;

[0117] The number of times the terminal device continuously experiences unsuccessful random access procedures for requesting system information reaches a maximum number configured by the network device;

[0118] The number of times the terminal device sends a system information request to the network device reaches the maximum number configured by the network device for the terminal device;

[0119] Cell reselection occurs before the network device initiates a random access procedure for requesting system information;

[0120] When a cell reselection occurs during a random access process performed by a network device for requesting system information, the terminal device enters an idle state;

[0121] The terminal device detects the first system information in a system broadcast without requesting the first system information.

[0122] Optionally, the second condition includes at least one of the following:

[0123] The terminal device successfully accesses the cell;

[0124] The system information required by the terminal device changes;

[0125] The number of times the terminal device sends a system information request to the network device reaches the maximum number configured by the network device for the terminal device;

[0126] The process of the terminal device sending a system information request to the network device fails to complete successfully;

[0127] The terminal device detects the first system information in a system broadcast without requesting the first system information.

[0128] Optionally, the process of the terminal device sending a system information request to the network device fails to be successfully completed, including: a radio link failure RLF or handover occurs during the process of the terminal device requesting system information.

[0129] Optionally, the terminal device 100 further includes: a sending module, configured to report relevant information of the system information request to the network device based on a logged minimization of drive test mode Logged MDT and / or an immediate minimization of drive test mode Immediate MDT.
