[0032] Figure 1The block diagram of a wireless communication system to which the embodiments of the present application can be applied is shown. The wireless communication system includes a terminal 11 and a network-side device 12. Among them, the terminal 11 can be a mobile phone, a tablet personal computer, a laptop computer, a notebook computer, a personal digital assistant (PDA), a handheld computer, a netbook, an ultra-mobile personal computer (UMPC), a mobile internet device (MID), an augmented reality (AR), a virtual reality (VR) device, a robot, a wearable device, a flight vehicle, a vehicle user equipment (VUE), a shipborne device, a pedestrian user equipment (PUE), a smart home (home appliances with wireless communication functions, such as refrigerators, TVs, washing machines or furniture, etc.), a game console, a personal computer (PC), a teller machine or a self-service machine, etc. Wearable devices include: smart watches, smart bracelets, smart earphones, smart glasses, smart jewelry (smart bracelets, smart bracelets, smart rings, smart necklaces, smart anklets, smart ankle chains, etc.), smart wristbands, smart clothing, etc. Among them, the vehicle user equipment can also be referred to as a vehicle terminal, a vehicle controller, a vehicle module, a vehicle component, a vehicle chip or a vehicle unit, etc. It should be noted that the specific type of the terminal 11 is not limited in the embodiments of the present application. The network-side device 12 can include an access network device or a core network device. Among them, the access network device can also be referred to as a radio access network (RAN) device, a radio access network function or a radio access network unit. The access network device can include a base station, a wireless local area network (WLAN) access point (AP) or a wireless fidelity (WiFi) node, etc.Among them, the base station can be referred to as Node B (NB), Evolved Node B (eNB), the next generation Node B (gNB), New Radio Node B (NR Node B), access point, Relay Base Station (RBS), Serving Base Station (SBS), Base Transceiver Station (BTS), radio base station, radio transceiver, Basic Service Set (BSS), Extended Service Set (ESS), home Node B (HNB), home evolved Node B, Transmission Reception Point (TRP), or some other suitable term in the art. As long as the same technical effect is achieved, the base station is not limited to specific technical terms. It should be noted that in the embodiments of this application, only the base station in the NR system is taken as an example for introduction, and the specific type of the base station is not limited.

[0033] The core network device may include, but is not limited to, at least one of the following: core network node, core network function, Mobility Management Entity (MME), Access and Mobility Management Function (AMF), Session Management Function (SMF), User Plane Function (UPF), Policy Control Function (PCF), Policy and Charging Rules Function (PCRF), Edge Application Server Discovery Function (EASDF), Unified Data Management (UDM), Unified Data Repository (UDR), Home Subscriber Server (HSS), Centralized network configuration (CNC), Network Repository Function (NRF), Network Exposure Function (NEF), Local NEF (L-NEF), Binding Support Function (BSF), Application Function (AF), etc. It should be noted that in the embodiments of this application, only the core network devices in the NR system are taken as examples for introduction, and the specific types of core network devices are not limited.

[0034] In the related art, the Internet access service may include the uplink service and the downlink service. For the uplink service disconnection, it can be determined whether the uplink service demand cannot be met due to insufficient network scheduling through the Buffer Status Report (BSR).

[0035] For the downlink service disconnection, for example, for common services such as abnormal short video playback, possible problems may include at least one of the following: no downlink data due to server overload; no downlink data due to network resource scheduling; packet parsing failure due to demodulation or interference at the terminal side.

However, in related technologies, the terminal can only judge service anomalies based on the terminal's historical data and experience and determine the implemented policy, which may cause problems such as ineffective policies.

[0038] To solve this problem, an information acquisition solution is provided in an embodiment of the present application.

[0039] The technical solutions provided in the embodiments of the present application will be described in detail below with reference to the accompanying drawings through some embodiments and their application scenarios.

[0040] Figure 2 FIG. shows a schematic flowchart of an information acquisition method in an embodiment of the present application. The method 200 can be executed by a terminal. In other words, the method can be executed by software or hardware installed on the terminal. As Figure 2 shown, the method may include the following steps.

[0041] S210, the terminal acquires first information sent by a network-side device, where the first information is used to indicate information related to disconnection.

[0042] In an embodiment of the application, disconnection refers to service anomalies. For example, video service stuttering, or large network response latency, etc.

[0043] In an embodiment of the present application, the information related to disconnection refers to information related to service anomalies. Through the information related to disconnection, the terminal can analyze relevant information about disconnection on the network side. For example, the cause value of service stuttering, the time corresponding to service anomalies, etc.

[0044] In an optional implementation manner, the first information may include second information of at least one first cell, and the at least one first cell may include the serving cell of the terminal and / or at least one neighboring cell of the serving cell. The second information may include at least one of the following:

[0045] (1) The cause value of service stuttering; in this optional implementation manner, the network-side device can indicate the cause value of the current service stuttering to the terminal through the second information, so that the terminal can know why the current service stuttering occurs, and then can execute corresponding optimization operations to recover from the stuttering state.

[0046] Optionally, the cause value of service jamming can be used to indicate at least one of the following:

[0047] (1) Server overload; The network-side device can know whether the current server is overloaded. In the case of server overload, the cause value of service jamming can be set to a value corresponding to server overload, so as to indicate to the terminal that the current server is overloaded.

[0048] (2) The network-side device has no downlink resource scheduling; If the network-side device currently has no downlink resource scheduling, the cause value of service jamming can be set to a value corresponding to the network-side device having no downlink resource scheduling, so as to indicate to the terminal that the network-side device has no downlink resource scheduling.

[0049] (3) The network side has no uplink resource scheduling; If the network-side device currently has no uplink resource scheduling, the cause value of service jamming can be set to a value corresponding to the network-side device having no uplink resource scheduling, so as to indicate to the terminal that the network-side device has no uplink resource scheduling.

[0050] (4) Demodulation on the terminal side causes packet parsing failure; If packet parsing fails due to demodulation on the terminal side, the network-side device can set the cause value of service jamming to a value corresponding to demodulation on the terminal side causing packet parsing failure, so as to indicate that the reason for the terminal jamming is that demodulation on the terminal side causes packet parsing failure.

[0051] (5) Interference on the terminal side causes packet parsing failure; If packet parsing fails due to interference on the terminal side, the network-side device can set the cause value of service jamming to a value corresponding to interference on the terminal side causing packet parsing failure, so as to indicate that the reason for the terminal jamming is that interference on the terminal side causes packet parsing failure.

[0052] (6) Related to the service load of the network-side device; For example, the service load of the network-side device is too large.

[0053] (7) The capability of the terminal is lower than the capability reported by the terminal during the capability reporting process. That is, the current capability of the terminal is lower than the nominal capability. In the case where the current capability of the terminal is lower than the capability reported by the terminal during the capability reporting process, the network may configure the behavior of the terminal according to the nominal capability of the terminal. However, since the capability of the terminal is lower than the nominal capability, the terminal cannot execute the operations corresponding to the network-side configuration well, resulting in service jamming.

[0054] (2) First-time information, which is used to indicate the first time corresponding to the service anomaly; the network-side device may include in the second information the first-time information indicating the first time corresponding to the service anomaly, so that the terminal can know the time when the network-side device senses the service anomaly. For example, the service anomaly may include abnormal video playback (such as stuttering), abnormal voice call, and abnormal text reception / transmission.

[0055] (3) The first utilization rate of the Physical Resource Block (PRB). The network-side device may include in the second information the first utilization rate of the PRB, so that the terminal can know the first utilization rate of the PRB, and then determine the current network condition according to the first utilization rate of the PRB.

[0056] Optionally, the first utilization rate of the PRB may be the first utilization rate of the PRB within a unit time. For example, before the first time, the utilization rate of the PRB within a unit time. For another example, the statistical time of the first utilization rate of the PRB may be a period of time before the first time, that is, within 2 minutes before the first time, the utilization rate of the PRB.

[0057] (4) The second utilization rate of the Control Channel Element (CCE) of the Physical Downlink Control Channel (PDCCH) for uplink scheduling or downlink scheduling; the network-side device may include in the second information the second utilization rate of the PDCCH CCE, so that the terminal can know the second utilization rate of the PDCCH CCE, and then determine the current network condition according to the second utilization rate of the PDCCH CCE.

[0058] Optionally, the second utilization rate of the PDCCH CCE may be the second utilization rate of the PDCCH CCE within a unit time. For example, before the first time, the second utilization rate of the PDCCH CCE within a unit time. For example, the statistical time of the second utilization rate of the PDCCH CCE may be a period of time before the first time, that is, within 2 minutes before the first time, the utilization rate of the PDCCH CCE.

[0059] (5) The Packet Data Convergence Protocol (PDCP) delay; the network-side device may include in the second information the PDCP delay of the terminal, so that the terminal can know its PDCP delay, and then determine the current network transmission condition according to the PDCP delay.

[0060] Optionally, the PDCP delay may be the PDCP delay of the terminal within a period of time before the first time.

[0061] (6) The service load status of the network side device; for example, the arrival percentage, or the service load level (e.g., high or low). The network side device may include the service load status of the network side device in the second information, so that the terminal can learn the service load status of the network side device, and then determine the current network condition according to the service load status of the network side device.

[0062] Optionally, the service load status of the network side device may be the service load status of the network side device within a unit time. For example, before the first time, the service load status of the network side device within a unit time. For example, the service load status is the statistical result of a period of time.

[0063] In some embodiments, the service load information may include at least one of the following: current service load information and predicted service load information. Exemplarily, "current" may refer to the time point corresponding to the service anomaly (e.g., the first time), or may refer to the time point when the network side device sends the first information. Exemplarily, "predicted service load information" may refer to the service load information within a future period of time, and this period of time may be sent to the terminal or agreed by the protocol.

[0064] Exemplarily, the service load information may be represented by a percentage. For example, the service reaches 80%.

[0065] Exemplarily, the service load information may be represented by a level. For example, the predefined service load level is from 1 to 10, and the larger the number, the higher the service load.

[0066] (7) The number of first users in the Radio Resource Control (RRC) connected state; the network side device may include the number of first users currently in the RRC connected state in the second information, so that the terminal can learn the number of first users currently in the RRC connected state of the network side device, and then determine the load of the network side device or the cause of the service anomaly according to the number of first users currently in the RRC connected state of the network side device.

[0067] Optionally, the number of first users in the RRC connected state may be the number of first users in the RRC connected state within a unit time. For example, before the first time, the number of first users in the RRC connected state within a unit time. For example, the number of first users in the RRC connected state is the statistical result of a period of time.

[0068] (8) The number of second users in the RRC active state; The network device may include, in the second information, the number of second users currently in the RRC active state, so that the terminal can know the number of second users currently in the RRC active state of the network device, and further determine the load of the network device or the cause of service anomaly according to the number of first users currently in the RRC active state of the network device.

[0069] Optionally, the number of second users in the RRC active state may be the number of second users in the RRC active state per unit time. For example, before the first time, the number of second users in the RRC active state per unit time. For example, the number of second users in the RRC active state is the statistical result of a period of time.

[0070] (9) The target ratio of the number of first users in the RRC connected state to the number of users that the network device can support; The network device may include, in the second information, the target ratio of the number of first users currently in the RRC connected state to the number of users that the network device can support, so that the terminal can know the target ratio of the number of first users currently in the RRC connected state to the number of users that the network device can support, and further determine the load of the network device or the cause of service anomaly according to the target ratio of the number of first users currently in the RRC connected state to the number of users that the network device can support.

[0071] Optionally, the target ratio of the number of first users in the RRC connected state to the number of users that the network device can support may be the ratio of the number of first users in the RRC connected state per unit time to the number of users that the network device can support. For example, before the first time, the ratio of the number of first users in the RRC connected state per unit time to the number of users that the network device can support. For example, the target ratio of the number of first users in the RRC connected state to the number of users that the network device can support is the statistical result of a period of time.

[0072] (10) The uplink signal measurement result; The network device may include, in the second information, the current uplink signal measurement result, so that the terminal can know the uplink signal measurement result obtained by the network device for measuring the uplink signal, and further determine the quality information of the current uplink channel or the cause of service anomaly according to the uplink signal measurement result.

[0073] For example, the uplink signal measurement result may include a Reference Signal Received Power (RSRP) measurement result or a Signal-to-Noise and Interference Ratio (SINR) measurement result. Optionally, the measurement result of the uplink signal may be the measurement result already available to the network when the first information is sent; optionally, the measurement result of the uplink signal may be the measurement result already available to the network when a service anomaly occurs; optionally, the uplink signal measurement result may be the uplink signal measurement result within a unit time. For example, before the first time, the uplink signal measurement result within a unit time. For example, the uplink signal measurement result is a statistical result over a period of time.

[0074] It should be noted that the above unit time may be a preset unit granularity, and the unit of the above unit time may be seconds, milliseconds, microseconds, frames, sub-frames, symbols, time slots, etc. For example, 1 minute, one time slot, multiple time slots, etc., which can be specifically determined according to actual applications and are not limited in the embodiments of the present application.

[0075] In an alternative implementation, the terminal may obtain the above first information through dedicated signaling. For example, an RRC message, a Non-Access Stratum (NAS) message. Additionally, the NAS message may deliver the first information to the Access Stratum (AS).

[0076] In the embodiments of the present application, the terminal may obtain the first information from the network-side device. According to the indication of the first information, the terminal may obtain information related to disconnection, avoiding the problem that the data basis for the UE to perform service anomaly analysis is insufficient, so that the information related to disconnection obtained by the terminal is more comprehensive, and further ensuring the effectiveness of the subsequent optimization strategy executed by the terminal.

[0077] In an alternative implementation, after S210, the method may further include: the terminal analyzes the disconnection reason of the serving cell based on the first information. For example, based on the first information, the terminal may analyze that the reason for the disconnection is: for example, the reason is network congestion, high network service load, poor link environment, or terminal itself problem (such as the ability is lower than the nominal ability), etc.

[0078] In an alternative implementation, after S210, the method may further include: the terminal performs a target operation based on the first information, where the target operation includes at least one of the following:

[0079] (1) Cell handover; for example, when the terminal analyzes that the reason for the disconnection is high network load and determines that the load of a certain neighboring cell is relatively low based on the second information of the neighboring cell, the terminal can independently disconnect from the serving cell and actively hand over to a neighboring cell with good service status.

[0080] (2) Cell redirection; for example, the terminal can be redirected to other cells other than the current serving cell.

[0081] (3) Connection reestablishment; for example, when the terminal analyzes that the reason for the disconnection is poor link environment, the terminal can perform connection reestablishment in order to recover from the current state. For example, in the case of disconnection, the terminal can trigger a Radio Link Failure (RLF).

[0082] (4) Cell selection; for example, when the terminal analyzes that the current serving cell is network congested based on the first information, the terminal can perform cell selection to select other cells to camp on.

[0083] (5) Cell reselection; for example, when the terminal analyzes that the current serving cell is network congested based on the first information, the terminal can perform cell reselection to select other cells to camp on.

[0084] (6) Activate a deactivated cell; for example, when the terminal analyzes that all currently activated cells are not suitable based on the first information, the terminal can activate the deactivated cell, and then can further choose to connect to this cell or choose to camp on this cell.

[0085] (7) Enter the idle state; for example, when the terminal analyzes that the current network is congested or has high network load based on the first information, the terminal can enter the idle state to relieve network congestion or network load, and can subsequently choose to camp on and access other cells.

[0086] (8) Leave the connected state; for example, when the terminal analyzes that the current network is congested or has high network load based on the first information, the terminal can leave the connected state, for example, enter the idle state or the deactivated state, to relieve network congestion or network load, and can subsequently choose to camp on and / or access other cells.

[0087] (9) Shutdown; for example, when the terminal analyzes that the reason for the disconnection is a problem with the terminal itself based on the first information, the terminal can shut down and then restart in order to get out of the current disconnection state.

[0088] (10) Enter the flight mode; for example, when the terminal analyzes that the reason for the disconnection is a problem with the terminal itself based on the first information, the terminal can enter the flight mode and then switch to the normal mode in order to get out of the current disconnection state.

[0089] (11) Perform a handover between radio access technologies (inter-RAT); for example, actively handover to a cell of another radio access technology.

[0090] (12) Determine that the serving cell of the terminal is prohibited. For example, when it is analyzed that the cause of the disconnection is at least one of network congestion, high network load, and poor link environment in the serving cell, the terminal can consider that the current serving cell is prohibited, and subsequently can select other cells to camp on and / or access.

[0091] Through the above implementation method, the terminal can perform corresponding operations based on the first information to recover from the current disconnection state and optimize the subsequent communication quality.

[0092] In an alternative implementation, after S210, the method further includes: the terminal sends auxiliary information to the network-side device, where the auxiliary information includes at least one of the following:

[0093] (1) First indication information for indicating that a disconnection has occurred in the serving cell; in this implementation, the first indication information indicates that a disconnection has occurred in the serving cell. The first indication information can be per cell (i.e., indicating that a disconnection has occurred in this serving cell), or per network (e.g., PLMN) (i.e., indicating that a disconnection has occurred in a certain / some networks in this serving cell). If the indication is per network, additionally, the terminal can also send the network identifier (e.g., PLMN ID) or network index (e.g., PLMN Index) corresponding to each first indication to the network-side device.

[0094] (2) The reason for the disconnection of the serving cell; for example, the above-analyzed network congestion, high network load, poor link environment, or problems with the terminal itself.

[0095] (3) The preferred operations of the terminal, where the preferred operations include at least one of the following: cell handover, cell redirection, connection reconstruction, cell selection, cell reselection, activating a shut-down cell, entering the idle state, leaving the connected state, shutting down, entering the flight mode;

[0096] (4) Information related to at least one cell that the terminal prefers to connect to, where the cell-related information includes at least one of the following: Cell Global Identifier (CGI), Physical Cell Identifier (PCI), carrier frequency information, Tracking Area Code (TAC), Tracking Area Identity (TAI).

[0097] Through the above implementation method, the terminal sends the above auxiliary information to the network-side device, so that the network-side device can learn about the disconnection reason and the tendency operation obtained by the terminal based on the first information.

[0098] In one implementation method, before S210, the method may further include: the terminal sends a target request to the network-side device, where the target request is used to request the first information. In this implementation method, the terminal requests the first information from the network-side device, and the network-side device sends the above first information to the terminal based on the request of the terminal. Optionally, the terminal may send the above target request to the network-side device when detecting service anomalies, for example, when the video service is stuck during playback, to request relevant information for disconnection optimization.

[0099] Optionally, the target request may carry at least one of the following information:

[0100] (1) A second indication information, which is used to indicate that the terminal requests the first information; through the second indication information, it can be indicated that the target request requests the above first information (this first information is used to indicate information related to disconnection, so it can also be called a disconnection report).

[0101] Optionally, the second indication information may further include a third indication information, which is used to indicate a request to obtain the second information of the serving cell and a request to obtain the second information of the neighboring cell; through the third indication information, it can be indicated to the network-side device that the terminal requests to obtain the second information of at least one of the serving cell and / or the neighboring cell, for example, requests to obtain the above second information of the serving cell and / or at least one neighboring cell.

[0102] For example, the third indication information may be used to indicate that only the second information of the serving cell or only the second information of the neighboring cell is required, or the second information of the serving cell and the neighboring cell is required. For example, for the second information of the neighboring cell, the network-side device selects which neighboring cells' second information to send to the terminal based on the implementation. For another example, the network-side device sends the second information of the neighboring cells included in the permission-related information to the terminal.

[0109] In an optional implementation, the terminal sending a target request to the network-side device may include: when a first condition is met, the terminal sends the target request to the network-side device.

[0110] In this implementation, the first condition may include at least one of the following:

[0111] (1) The measurement result of the downlink signal is greater than or equal to a first threshold;

[0112] (2) The downlink rate is less than or equal to a second threshold;

[0114] (4) The uplink rate is less than or equal to a fourth threshold.

[0115] In an optional implementation, the terminal may send a target request when the signal measurement result is good, but the downlink / uplink rate is poor.

[0116] In this optional implementation, when the first condition is met, the terminal sends a target request to the network-side device for requesting the above first information, so that when the terminal needs to obtain the above first information, it can request to obtain the first information.

[0117] In an optional implementation, the first condition may further include at least one of the following:

[0118] (1) Being located in an area where obtaining the first information is allowed; that is, the terminal sends the above target request in an area where obtaining the first information is permitted.

[0119] (2) Within the time when obtaining the first information is allowed. That is, the terminal sends the above target request within the time when obtaining the first information is permitted.

[0120] In another implementation, before S210, the method may further include: the terminal sending a first subscription indication to the network-side device, where the first subscription indication is used to indicate to the network-side device that the terminal has subscribed to the first information. In this optional implementation, the terminal may subscribe to the above-mentioned first information from the network-side device. Then, after obtaining the first information, the network-side device may send the first information to the terminal. Or, after receiving the target request sent by the terminal, the network-side device may send the above-mentioned first information to the terminal. Or, the network-side device may also periodically obtain the above-mentioned first information and then periodically send the above-mentioned first information to the terminal. Or, within a period of time, the network-side device may periodically obtain the above-mentioned first information and, when the obtained first information changes compared with the previous time or meets a predetermined condition, send the above-mentioned first information to the terminal.

[0121] In an optional implementation, before S210, the method may further include: the terminal obtaining third information, where the third information is used to indicate permission-related information for allowing the acquisition of the first information. In this implementation, through the third information, the terminal determines the permission-related information for allowing it to acquire the above-mentioned first information.

Through the fourth indication information, the terminal can learn whether it is allowed to acquire the first information and send the above-mentioned target request.

[0124] Among them, the third indication information may be an explicit indication or an implicit indication. For example, if the third indication information includes any disconnection information reporting permission-related information (such as the area information and time information mentioned later), it may implicitly indicate that the function of acquiring the first information is activated. If it is an explicit indication, the third indication information may be represented by 1 bit. For example, if the value of this bit is 1 / true, the function of acquiring the first information is activated; if the value of this bit is 0 / false, it means that the function of acquiring the first information is not activated. Another example is that if this bit exists and the value is true, it means that the function of acquiring the first information is activated.

[0125] (2) Information related to at least one second cell, which is used to indicate that it is allowed to obtain the second information of the at least one second cell; through the information related to the at least one second cell, the terminal can know that it is allowed to obtain the second information of the at least one second cell.

[0130] The TAC of the at least one second cell;

[0132] It can be understood that if the network configures the information related to at least one second cell, that is, the network side configures which cells' second information is allowed for the terminal to obtain, then at least one first cell included in the target request sent by the terminal to the network side device is a subset of the "at least one second cell".

During the running of this first timer, the function of obtaining the first information is activated. If this first timer times out, the function of obtaining the first information is deactivated.

[0144] (2) The start point and duration of the second timer, which indicates that the terminal starts the second timer at the time indicated by the start point of the second timer, and obtaining the first information is allowed during the running of the first timer; In this optional implementation manner, the terminal starts the second timer at the time indicated by the start point of the second timer, and the running length of the second timer is the length of the second timer.

[0153] Optionally, the unit of the length of each of the above timers or time windows can be represented by any one of hour, minute, second, millisecond, microsecond, frame, sub-frame, symbol, and time slot.

[0158] If the network-side device is a core network device, the core network may send the third information through dedicated signaling (such as NAS signaling). Additionally, when the NAS layer of the terminal receives the third information, it delivers the third information to the AS layer. Additionally, the core network instructs the RAN to allow the terminal to obtain the first information.
