[0043] The following will describe the embodiments of this application in more detail with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other.

[0044] The execution subject of the communication method provided in this embodiment can be a communication device or a communication device, such as an electronic device or a chip, etc.

[0045] To address the technical issue of the inconsistent protocol states between the network and the terminal after the terminal receives the RRC reconfiguration message timeout release during the current connection reconstruction process and improve communication efficiency, this embodiment provides a communication method that can be executed by a network device, such as Figure 1 As shown, the method includes:

[0046] Step 101: Set a first timer in response to a Radio Resource Control (RRC) reconstruction request sent by the terminal.

[0047] Step 102: Send an RRC reconstruction message to the terminal.

[0048] In some examples, the terminal is the terminal device, which can also be referred to as a user equipment (UE), a mobile station (MS), a mobile terminal (MT), etc. The terminal device can also be a car with communication capabilities, a smart car, a mobile phone, a wearable device, a tablet (Pad), a computer with wireless transceiver capabilities, a Virtual Reality (VR) device, an Augmented Reality (AR) device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, a wireless terminal device in a smart home, or it can also be a chip or a chip system, etc. The embodiments of this application do not limit the specific technologies and specific device forms adopted by the terminal device.

[0049] In some embodiments, the network device may be a device such as a base station or a satellite. In the embodiments of the present application, there is no specific limitation. The network device may be an entity on the network side for transmitting or receiving signals. For example, the network may be a communication satellite, an evolved NodeB (eNB), a transmission reception point (TRP), a next generation NodeB (gNB) in an NR system, a base station in other future mobile communication systems, or an access node in a wireless fidelity (WiFi) system, etc. The embodiments of the present disclosure do not limit the specific technologies and specific device forms adopted by the network device.

[0050] The network device provided in the embodiments of the present disclosure may be composed of a central unit (CU) and a distributed unit (DU). Among them, the CU may also be referred to as a control unit. The use of the CU-DU structure can split the protocol layer of the network device, such as a base station. The functions of some protocol layers are centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers are distributed in the DU, and the DU is centrally controlled by the CU.

[0051] When the terminal is in the RRC connected state of the Fifth-generation (5G) mobile communication technology, due to abnormalities such as abnormal underlying links or the maximum number of retransmissions being reached, the 5G RRC connection becomes abnormal. The 5G RRC will restore the connection through a reconstruction process to ensure the continuous progress of services.

[0052] In LTE and 5G NR, RRC (Radio Resource Control) is the main control protocol between the radio access network (RAN) and the terminal (such as a mobile phone). It handles all control plane functions related to network access, radio resource configuration, mobility management, security, etc. RRC reestablishment is the process by which the UE reestablishes the RRC connection with the network side to restore communication. When the UE detects a radio link failure (e.g., due to a severe drop or complete loss of signal quality), it attempts to perform RRC reestablishment. The UE sends an RRC reestablishment request (RRC Reestablishment Request) to the network side. Subsequently, the network side will feedback an RRC reestablishment message (RRC Reestablishment) to the UE. The reestablishment message contains information required to reestablish the connection, such as the UE's identification, and also includes a second timer. The second timer is used for the terminal to determine whether it receives an RRC reconfiguration message within a preset duration. The first timer is used for the network device to determine whether the terminal receives an RRC reconfiguration message within a preset duration. In a wireless network, the RRC timer indicates the limited time for the UE to execute a certain event and defines the scenarios for the start and stop of the event and the subsequent processing method of the UE after timeout.

[0053] It should be emphasized here that the preset duration refers to the set duration of the first timer. The sent second timer can be the same as the preset duration of the first timer or slightly deviate from the preset duration. For example, the first timer is set to 300 ms and the second timer is set to 280 ms. Except for the setting of the preset duration, the essence of the two timers is the same. The main function of the timer is to determine whether the UE receives an RRC reconfiguration message within the preset duration, so as to avoid inconsistent protocol states at both ends. For the convenience of reflecting the consistency at both ends in the following embodiments, it is defaulted that the preset durations of the first timer and the second timer are the same in the following embodiments.

[0054] When the network side receives the RRC reestablishment request sent by the UE, it sets the first timer and carries the second timer in the RRC reestablishment message (MSG4) sent to the UE, so that both the network side and the UE have this timer, facilitating the subsequent timely release of resources by both parties based on the timer. By adding a timer to the RRC reconfiguration message sent to the terminal and timing at both ends, it is possible to determine whether the UE receives an RRC reconfiguration message within the preset duration based on the timer, thus avoiding inconsistent protocol states and the problem of low communication efficiency, and improving the user experience.

[0055] Optionally, after sending the RRC reestablishment message to the terminal, the method further includes: in the case of receiving the RRC reestablishment complete message sent by the terminal, starting the first timer and sending an RRC reconfiguration message to the terminal.

[0056] In this embodiment, when the UE successfully completes the RRC reconstruction process, it sends an RRC reconstruction complete message to the network side to confirm that the reconstruction process has been completed and that the UE is now ready to continue communication. After receiving the UE's RRC reconstruction complete message, the network side evaluates the current radio environment and network conditions and may decide to further configure or optimize the UE. While sending the RRC reconfiguration message, the network side (and the UE side after receiving the RRC reconstruction message) starts a first timer.

[0057] Optionally, after sending the RRC reconfiguration message to the terminal, the method further includes: releasing the context of the terminal when the RRC reconfiguration complete message feedback from the terminal is not received and a preset duration has elapsed.

[0058] In this embodiment, RRC reconfiguration is a process that requires the UE to change its radio resource configuration to adapt to changes in network conditions or optimize resource usage. When the UE successfully applies the RRC reconfiguration message sent by the network side (such as a base station), it sends an RRC reconfiguration complete message to the base station to confirm that the configuration change has been successfully executed. If the network side has not received the UE's RRC reconfiguration complete message, after the first timer times out, in this case, in order to effectively manage network resources and avoid resource waste, the base station releases the current service resources and context data related to the UE to ensure the effective utilization of network resources and the stability of the network.

[0059] Optionally, after sending the RRC reconfiguration message to the terminal, the method further includes: stopping the first timer when an acknowledgment frame sent by the terminal is received.

[0060] In this embodiment, the acknowledgment frame (such as the RRC reconfiguration complete message) is sent by the UE to the network side to confirm that it has successfully received and applied the RRC reconfiguration message sent by the network side. The acknowledgment frame is part of the reliable communication mechanism in wireless communication to ensure that both parties have the same understanding of the configuration change or data transmission. If the UE successfully applies the new configuration and sends the acknowledgment frame, the network side will receive this acknowledgment frame. After receiving the acknowledgment frame, the network side knows that the UE has successfully completed the required operation, so it no longer needs to wait for more time. In this case, the network side stops the previously started first timer because the main purpose of the timer (waiting for the UE's response to the RRC reconfiguration message within a specified time) has been achieved.

[0061] Correspondingly, this embodiment further provides a communication method applied to the terminal side, including: when detecting a trigger for link reconstruction, sending a Radio Resource Control (RRC) reconstruction request to a network device; receiving an RRC reconstruction message sent by the network device; wherein, the RRC reconstruction message includes a second timer, and the second timer is used for the terminal to determine whether an RRC reconfiguration message is received within a preset duration.

[0062] Link reconstruction refers to the situation where, in some cases, such as a sharp drop in wireless signal quality, base station failure, or the terminal moving to a new service area, the current wireless link may not be maintained. To restore the connection and continue providing services, the system may attempt to perform link reconstruction. Once the UE determines that link reconstruction is required, it sends a reconstruction request to the network side through the RRC layer.

[0063] The network sends an RRC reconstruction message to the UE. In the RRC reconstruction message, the network device includes a timer. Here, the timer in the RRC reconstruction message is also the second timer, which is used for the terminal to determine whether an RRC reconfiguration message is received within a preset duration.

[0064] Optionally, after receiving the RRC reconstruction message sent by the network device, the method further includes: sending an RRC reconstruction complete message to the network device and starting the second timer.

[0065] In this embodiment, when the UE successfully receives the RRC reconstruction message, it sends an RRC reconstruction complete message to the network device. This message indicates that the UE has successfully completed the RRC reconstruction process and is ready to continue the previous communication session. After the RRC reconstruction is completed, the UE starts the second timer to monitor and manage subsequent operations or processes. It should be noted that the execution order of the UE sending the RRC reconstruction complete message and starting the second timer is not limited. It can send the RRC reconstruction complete message first and then start the timer, or both can be performed simultaneously.

[0066] Meanwhile, the network side also starts a first timer and sends an RRC reconfiguration message after receiving the RRC reconstruction complete message.

[0067] Optionally, after sending the RRC reconstruction complete message to the network device, the method further includes: releasing the current service resources when the RRC reconfiguration message is not received and after a preset duration.

[0068] In this embodiment, after the timer is started on both the network side and the UE, if the UE does not receive an RRC reconfiguration message from the network side within a preset duration, it may indicate problems with the network environment or the UE itself, such as network failures, signaling loss, or incorrect network configuration. To ensure the effective utilization of resources and the stability of the network, the current radio connection state is considered invalid or no longer required at this time, and the UE releases the current service resources. At the same time, when the network side does not receive the reconfiguration complete information from the UE, it will also release the corresponding service resources. This avoids inconsistent protocol states and problems of low communication efficiency, and improves resource utilization.

[0069] Optionally, after sending an RRC reestablishment complete message to the network device, the method further includes: stopping the second timer and sending an acknowledgment frame to the network device when an RRC reconfiguration message sent by the network device is received within a preset duration.

[0070] In this embodiment, when the UE receives an RRC reconfiguration message from the network device within a preset duration, the previously started second timer is stopped. After receiving the RRC reconfiguration message, the UE sends an acknowledgment frame to the network device to confirm that it has successfully received the message. Next, the UE configures parameters according to the instructions in the received RRC reconfiguration message. After completing the parameter configuration, the UE sends an RRC reconfiguration complete message (RRCReconfigurationComplete). This message indicates that the UE has successfully applied the parameter configuration in the RRC reconfiguration message and is ready to continue executing the current service. After sending the RRC reconfiguration complete message, the UE will continue to execute its current service using the updated radio resource configuration according to the RRC reconfiguration message.

[0071] Furthermore, to illustrate the specific implementation process of this embodiment, the following specific application examples are given, but are not limited thereto. In addition, this embodiment can be applied not only to 5G technology but also to 4G technology:

[0072] This embodiment uses the protocol protection timer T500, 38331 as an example:

[0073] T500 can be carried to the UE through the RRCReestablishment message:

[0074] Timer start time point: Start the T500 protection timer after reestablishment is completed

[0075] Timer end time point: Receive the first reconfiguration message RRCReconfiguration or the RRCRelease message from the network after reestablishment.

[0076] Timer timeout handling: When the T500 timer times out, the release process is triggered.

[0077] As Figure 2 shown, a schematic diagram of the interaction process of a communication method provided in this embodiment is shown, that is, the flowchart of the non-timeout processing of the T500 protection timer. The specific process is as follows:

[0078] 1. The UE's radio link anomaly triggers a reconstruction, and the UE sends an RRCReestablishmentRequest to the network.

[0079] 2. The network responds to the UE's RRCReestablishment message and carries the T500 timer, and the UE saves the T500 duration.

[0080] 3. After the UE completes the reconstruction, it sends an RRCReestablishmentComplete message to the network and starts the T500 protection timer. After receiving the RRCReestablishmentComplete message, the network also starts the T500 protection timer.

[0081] 4. When the UE receives the first reconfiguration message RRCReconfiguration after reconstruction, it stops the T500 protection timer. After the UE successfully completes the reconfiguration process, it sends an RRCReconfigurationComplete to the network and continues to execute the service.

[0082] As Figure 3 shown, a schematic diagram of the interaction process of another communication method provided in this embodiment is shown, that is, the flowchart of the timeout processing of the T500 protection timer. The specific process is as follows:

[0083] 1. The UE's radio link anomaly triggers a reconstruction, and the UE sends an RRCReestablishmentRequest to the network

[0084] 2. The network responds to the UE's RRCReestablishment message and carries the T500 timer, and the UE saves the T500 duration

[0085] 3. After the UE completes the reconstruction, it sends an RRCReestablishmentComplete message to the network and starts the T500 protection timer. After receiving the RRCReestablishmentComplete message, the network also starts the T500 protection timer.

[0086] 4. If the UE fails to receive the reconfiguration stream due to an abnormal network environment, the T500 timer of the UE times out, triggering a release process. At the same time, the T500 timer of the network also times out, releasing the UE context.

[0087] Further, as Figures 1 to 3 a specific implementation of the method shown, this embodiment provides a communication device, as Figure 4 shown. The device includes: a first configuration module 41 and a first transmission module 42.

[0088] The first configuration module 41 is configured to set a first timer in response to a radio resource control (RRC) reconstruction request sent by a terminal.

[0089] The first transmission module 42 is configured to send an RRC reconstruction message to the terminal.

[0090] Wherein, the RRC reconstruction message includes a second timer, which is used by the terminal to determine whether an RRC reconfiguration message is received within a preset duration, and the first timer is used by the network device to determine whether the terminal receives the RRC reconfiguration message within the preset duration.

[0091] In some examples of this embodiment, the first transmission module 42 is configured to start the first timer and send an RRC reconfiguration message to the terminal when receiving an RRC reconstruction completion message sent by the terminal.

[0092] In some examples of this embodiment, the first transmission module 42 is further specifically configured to release the context of the terminal when the RRC reconfiguration completion message feedback from the terminal is not received and the preset duration has elapsed.

[0093] In some examples of this embodiment, the first transmission module 42 is further specifically configured to stop the first timer when receiving an acknowledgment frame sent by the terminal.

[0094] Further, as Figures 1 to 3 a specific implementation of the method shown, this embodiment provides a communication device, as Figure 5 shown. The device includes: a second transmission module 51 and a reception module 52.

[0095] The second transmission module 51 is configured to send a radio resource control (RRC) reconstruction request to a network device when detecting a trigger for link reconstruction.

[0096] The reception module 52 is configured to receive the RRC reconstruction message sent by the network device.

[0097] Among them, a second timer is included in the RRC reestablishment message, and the second timer is used for the terminal to determine whether an RRC reconfiguration message is received within a preset duration.

[0098] In some examples of this embodiment, the receiving module 52 is further configured to send an RRC reestablishment completion message to the network device and start the second timer.

[0099] In some examples of this embodiment, the receiving module 52 is further configured to release the current service resources when the RRC reconfiguration message is not received and the preset duration has elapsed.

[0100] In some examples of this embodiment, the receiving module 52 is further configured to stop the second timer and send an acknowledgment frame to the network device when the RRC reconfiguration message sent by the network device is received within the preset duration.
