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

step 200, in the process of performing data transmission in a non-connection state, when determining that a preset trigger condition is met, the UE performs any one of the following operations:

the UE sends a first message to network equipment, wherein the first message comprises an indication message of time-out of 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 a non-connected state, for example, in an RRC IDLE state or an RRC inactive state, if there is a data transmission requirement, a small data transmission process is performed, and specifically, the message MSG3 carries data to be transmitted. When the UE performs the small data transmission SDT, if it is determined that the preset trigger condition is met, according to the requirement of the embodiment of the present application, the UE needs to perform the first operation.

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

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 (DataRadioBearer, DRB) or logical channel. The maximum count value of the counter may refer to the number of times the UE retransmits the data packet, or the number of packet losses.

And when the UE performs data transmission in a non-connection state, if the UE determines that the preset trigger condition is met, performing any operation as follows.

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 survival time corresponding to the UE is timeout. Specifically, after the UE determines that the preset trigger condition is met, the UE sends a first message to the network device, for example, the base station, where the first message may carry an indication message of time-out of the survival time corresponding to the UE, so as to inform the base station that the time-out of 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, for example RRC resume Request, or 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 the service synchronization signal block SSB and completes the data transmission by reselecting one service beam (beam).

Based on 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 under the condition that the message MSG3 retransmission scheduling or the random access contention window is received and overtime;

the UE starts the timer or starts the counter to count under the condition that the feedback is the fallback RAR or the MSGB window of the message is overtime;

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

Further, the process 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 invention provides a specific solution after the survival time is overtime in the process of executing the data transmission of the UE in the non-connection state, for example, the UE can actively send an indication to the network equipment, and the network side uses a more reliable transmission mode according to the indication of the UE or instructs the UE to enter the RRC connection state so as to ensure the data transmission efficiency.

Fig. 3 is a second flowchart of a processing method of service reliability according to an embodiment of the present application, where the method may be applied to a network device, for example, a base station, and as shown in fig. 3, the method at least includes the following steps:

step 300, a base station receives a first message sent by a UE, wherein the first message comprises an indication message of time-out of survival time corresponding to the UE;

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

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 (DataRadioBearer, DRB). The maximum count value of the counter may refer to the number of times the UE retransmits the data packet, or the number of packet losses.

In the process that the UE performs data transmission in the non-connection 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 that the survival time corresponding to the UE is overtime. Specifically, after the UE determines that the preset trigger condition is met, the UE sends a first message to the network device, for example, the base station, where the first message may carry an indication message of time-out of the survival time corresponding to the UE, so as to inform the base station that the time-out of 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 performs any one of the following operations;

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

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

scheduling by using a repeat mode; or (b)
