In the industrial internet, service demand parameters of part of periodic deterministic communication services are as shown in the following table, and survival time is introduced besides traditional parameters such as transmission interval, message size, time delay and the like.

Fig. 2 is a flowchart of a processing method for service reliability according to an embodiment of the present application, where the method may be applied to a user equipment UE, and as shown in fig. 2, the method at least includes the following steps:

step 200, in the process of executing data transmission in the non-connected state, when it is determined that a preset trigger condition is met, executing any one of the following operations:

the UE sends a first message to network equipment, wherein the first message comprises an indication message of the overtime of the survival time corresponding to the UE;

the UE sends a connection establishment request to network equipment;

the UE performs cell reselection;

the UE performs beam selection;

specifically, when the UE is in the unconnected state, for example, in the RRC IDLE state or the RRC inactive state, if there is a data transmission requirement, the UE performs a small data transmission process, specifically, carries data to be transmitted in the message MSG 3. When the UE executes the SDT, if it is determined that the preset trigger condition is met, the UE needs to execute a first operation according to the requirement of the embodiment of the present application.

Wherein the preset trigger condition is determined based on the corresponding survival time of the UE. In various embodiments of the present application, at least the following two preset trigger conditions determined based on the survival time may be provided. One preset trigger condition may be that a timer is overtime, that is, the timer is configured in advance based on the survival time, and after the timer is overtime after being started, the preset trigger condition is satisfied. Another preset trigger condition may be that the counter reaches a maximum count value, that is, the counter is configured in advance based on the survival time, and when the count value reaches the maximum count value after the counter is started, the preset trigger condition is satisfied.

Further, the length of the timer may be configured by the network device based on the time-to-live. The maximum count value of the counter may also be configured by the network device based on the time-to-live, and may be configured for one Data Radio Bearer (DRB) or logical channel. The maximum count value of the counter may refer to the number of times that the UE retransmits the data packet, or the number of times that the packet is lost.

When the UE performs data transmission in the non-connected state, if it is determined that the preset trigger condition is satisfied, any one of the following operations is performed.

One operation may be that the UE sends a first message to a network device, where the first message includes an indication message that a time-to-live corresponding to the UE is out of time. Specifically, after the UE determines that the preset trigger condition is met, the UE sends a first message to a network device, such as a base station, where the first message may carry an indication message indicating that the survival time corresponding to the UE is time out, so as to inform the base station that the survival time corresponding to the UE is time out, and ask the base station to perform subsequent corresponding processing. The indication message may be an RRC message or a MAC CE message.

Another operation may be that the UE sends a connection establishment Request, such as an RRC resume Request or an RRC setup Request, to the base station, so that the UE enters an RRC connected state to complete data transmission.

Yet another operation may be that the UE performs cell reselection and completes data transmission by re-accessing a new cell.

Yet another operation may be that the UE reselects a serving synchronization signal block SSB to complete data transmission by reselecting a serving beam (beam).

On the basis of the above embodiment, the process may further include any one of the following methods for starting a counter or a counter:

the UE starts the timer or starts the counter to count when receiving message MSG3 retransmission scheduling or the overtime of a random access contention window;

the UE starts the timer or starts the counter to count when receiving feedback that the feedback is fallback RAR or the message MSGB window is overtime;

and after the UE receives negative feedback or receives configuration authorization CG retransmission scheduling, starting the timer or starting the counter to count.

Further, the procedure may further include the UE stopping the timer or zeroing the counter if the UE receives the correct feedback from the network device.

The processing method for service reliability provided by the embodiment of the application provides a specific solution for the UE after the survivability time expires in the process of sending data in the non-connected state, for example, the UE may actively send an indication to the network device, and the network side uses a more reliable transmission mode according to the indication of the UE, or indicates the UE to enter the RRC connected state, so as to ensure the data sending efficiency.

step 300, a base station receives a first message sent by a UE, where the first message includes an indication message indicating that a survival time corresponding to the UE is overtime;

specifically, when the UE is in the unconnected state, for example, in the RRC IDLE state or the RRC inactive state, if there is a data transmission requirement, the UE executes a transmission process of the small data SDT, specifically, carries data to be transmitted in the message MSG 3. In the process of executing the SDT, if it is determined that the preset trigger condition is met, the UE needs to execute a first operation according to the requirements of the embodiment of the present application.

Further, the length of the timer may be configured by the network device based on the time-to-live. The maximum count value of the counter may also be configured by the network device based on the time-to-live and may be configured for a Data Radio Bearer (DRB). The maximum count value of the counter may refer to the number of times that the UE retransmits the data packet, or the number of times that the packet is lost.

In the process of performing data transmission by the UE in the non-connected state, if it is determined that the preset trigger condition is met, the first operation may be that the UE sends a first message to the network device, where the first message includes an indication message indicating that the survival time corresponding to the UE is out of time. Specifically, after the UE determines that the preset trigger condition is met, the UE sends a first message to a network device, such as a base station, where the first message may carry an indication message indicating that the survival time corresponding to the UE is time out, so as to inform the base station that the survival time corresponding to the UE is time out, and ask the base station to perform subsequent corresponding processing. The indication message may be an RRC message or a MAC CE message.

Step 301, the base station executes any one of the following operations;

instructing the UE to enter a Radio Resource Control (RRC) connection state; or

And indicating the UE to adopt a new transmission mode for data transmission.

After receiving the first message sent by the UE, the base station may enter a radio resource control, RRC, connected state by the UE to complete data transmission. The UE may also be instructed to perform data transmission by using a new transmission method, where the new transmission method may be:

scheduling by using a repeated repetition mode; or
