[0104] In some embodiments, the network device 102 may include at least one of an access network device and a core network device.

[0105] Optionally, the access network device is, for example, a node or device that accesses the terminal to the wireless network.

Optionally, the base station is, for example, a macro base station, a micro base station (also known as a small base station), a relay station, an access point, a 5G base station or a future base station, a satellite, a transmission point (TRP), a transmission point (TP), a mobile switching center, or other devices that perform base station functions in a communication system, etc., which are not specifically limited in the embodiments of the present disclosure.

[0107] In some embodiments, network device 102 is a core network device. A core network device can be a single device, including a first network element, a second network element, etc., or can be multiple devices or a group of devices, each including all or part of the first network element, the second network element, etc. The network element can be virtual or physical. The core network includes, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).

[0108] In some embodiments, the technical solution of the present disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0109] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0110] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0111] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or a portion thereof, but are not limited thereto. The entities shown in FIG1 are illustrative only. The communication system may include all or part of the entities shown in FIG1 , or may include other entities outside of FIG1 . The number and form of the entities are arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0112] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0113] In some embodiments, machine learning algorithms are one of the most important implementation methods of artificial intelligence technology. Machine learning can generate models from large amounts of training data, which can then be used to predict events. In many fields, models trained using machine learning can produce highly accurate predictions.

[0114] In some embodiments, the AI ​​model is trained using handover-related big data, and the AI ​​can predict the success rate of handover to a certain cell or the probability of handover failure or the probability of wireless link failure based on the real-time network environment of the UE.

[0115] In some embodiments, after the UE initiates a handover to the target cell, it starts the T304 timer, disconnects from the source cell, synchronizes with the target cell, and then accesses the target cell through a random access process.

[0116] In some embodiments, if the target cell is successfully accessed before the T304 timer expires, the handover is successful and the T304 timer is stopped. If the T304 timer expires, the handover fails.

[0117] In some embodiments, the UE's RRC (Radio Resource Control) layer starts a T310 timer after receiving N310 consecutive out-of-sync indications. If the T310 timer expires, a Radio Link Failure (RLF) is triggered. It should be noted that the parameter N310 represents the maximum number of consecutive out-of-sync indications received, and the T310 timer is triggered when the maximum number is reached.

[0118] In some embodiments, if N311 consecutive in-sync indications are received during the T310 timer, the T310 timer is stopped. It should be explained that the parameter N311 is used to set the maximum number of consecutive in-sync indications required to stop the T310 timer.

[0119] As can be seen, in some embodiments, the UE needs to wait for a timer to expire, such as T304 or T310, before determining that a handover failure or radio link failure has occurred. This requires the UE to wait for a certain period of time. During this period of time, the UE may not be able to maintain communication with the network, resulting in service interruption. In view of this, the embodiments of the present disclosure provide a communication method, terminal, network device, communication system, and storage medium, which enable the UE to shorten service interruptions caused by waiting for link failure.

[0120] FIG2 is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2 , the embodiment of the present disclosure relates to a communication method, and the method includes:

[0121] Step S201 : The network device 102 sends second information to the terminal 101 .

[0122] In some embodiments, the terminal 101 receives second information sent by the network device 102 .

[0123] In some embodiments, the second information is used to indicate to the terminal that the network device allows the terminal to determine whether a link failure will occur based on the predicted first information.

[0124] In some embodiments, the second information is used to indicate to the terminal that the network device allows the terminal to trigger a link failure operation when determining that a link failure will occur.

[0125] In some embodiments, the second information allows the UE to trigger a link failure operation based on the predicted result.

[0126] In some embodiments, the name of the second information is not limited, and it can be, for example, a specific instruction, a first instruction, etc.

[0127] In some embodiments, the network device sends the second information to the terminal via a system message and / or an RRC reconfiguration message.

[0128] For example, the network device sends a system message including the second information, and the terminal obtains the system message to obtain the second information.

[0129] For example, the network device sends an RRC reconfiguration message, the RRC reconfiguration message includes the second information, and the terminal obtains the RRC reconfiguration message to obtain the second information.

[0130] In step S202 , the network device 102 indicates a first threshold to the terminal 101 .

[0131] In some embodiments, the network device 102 sends third information to the terminal 101, where the third information is used to indicate the first threshold. That is, the first threshold is indicated by the network device.

[0132] In some embodiments, step S202 may be replaced by the terminal 101 determining the first threshold according to protocol regulations. That is, the first threshold is stipulated by the protocol.

[0133] In some embodiments, the first threshold is default information configured locally in the terminal 101 .

[0134] In some embodiments, the first threshold represents an upper limit or a lower limit of the first probability in the following embodiments.

[0135] In some embodiments, the name of the first threshold is not limited, and it can be, for example, a preset threshold, an upper limit, a lower limit, a value boundary, etc.

[0136] In step S203 , the terminal 101 determines whether the state of a specific timer satisfies a specific condition, and obtains the predicted first information.

[0137] In some embodiments, the specific timer may be T310, T304, or another timer that meets the conditions. Optionally, the other timer that meets the conditions has the same start conditions as T310 / T304, and the duration used to determine whether it has timed out is shorter than the duration used to determine whether T310 / T304 has timed out. In other words, the other timer that meets the conditions may be started at the same time as T310 / T304 and time out earlier than T310 / T304.

[0138] In some embodiments, the specific timer is started upon receiving an out-of-sync indication and / or a handover command. Optionally, the out-of-sync indication is out of sync. Optionally, the handover command is a reconfiguration message carrying "reconfigurationWithSync".

[0139] In some embodiments, the specified condition includes a timer starting to run and / or a timer timing out.

[0140] For example, if the state of the specific timer is a state in which the timer starts running, it can be determined that the state of the specific timer meets a specific condition.

[0141] For example, if the state of the specific timer is a timer timeout state, it can be determined that the state of the specific timer meets a specific condition.

[0142] In some embodiments, the terminal determines that the state of a specific timer satisfies a specific condition, and an implementation method for obtaining the predicted first information may be that the terminal determines that the state of the specific timer satisfies the specific condition, and the terminal instructs a trained AI model to predict the first information. For example, the terminal instructs the trained AI model to predict the first information based on information such as the terminal's current location, network environment, wireless network environment over a previous period of time, candidate cells, and measurement cells.

[0143] In some embodiments, the AI ​​model can be configured on the terminal 101, or the AI ​​model can be configured on other electronic devices that can communicate with the terminal 101, such as other terminals or network devices.

[0144] It should be noted that, in addition to predicting the first information through the AI ​​model, the terminal 101 may also obtain the first information through other prediction methods, for example, by calculating the first information through a prediction algorithm.

[0145] In some embodiments, the first information is used to characterize, determine, or judge whether a link failure occurs.

[0146] In some embodiments, the name of the first information is not limited, and it can be, for example, prediction information, prediction results, model output results, etc.

[0147] In some embodiments, the first information includes a first probability.

[0148] In some embodiments, the first probability is used to represent the success rate or handover failure rate or radio link failure probability of the terminal handing over to a certain cell. The name of the first probability is not limited, and it can be, for example, a success rate, a failure rate, a probability parameter, etc.

[0149] In some embodiments, the terminal may determine whether a link failure will occur based on the first information by: the terminal determines whether a link failure will occur based on whether a magnitude relationship between the first probability and a first threshold meets a requirement.

[0150] Step S204: If the magnitude relationship between the first probability in the first information and the first threshold meets the requirement, it is determined that a link failure will occur.

[0151] In some embodiments, the first probability is a probability of link failure. Accordingly, when the first probability is greater than or equal to a first threshold, it can be determined that the relationship between the first probability and the first threshold meets the requirement, and further, it can be determined that a link failure will occur.

[0152] In some embodiments, the first probability is the probability that link failure does not occur. Accordingly, when the first probability is less than the first threshold, it can be determined that the relationship between the first probability and the first threshold meets the requirement, and further it can be determined that link failure will occur.

[0153] In some embodiments, the link failure includes a cell handover failure and / or a radio link failure.

[0154] The name of the link failure is not limited, and it can be, for example, cell handover failure, wireless link failure, etc.

[0155] In some embodiments, if the terminal determines that a link failure will occur, it may instruct a specific timer to stop.

[0156] Step S205: trigger RRC reestablishment.
