The specific process of reporting the failure information is the same as the reporting process in the system supporting one conditional handover attempt, and is not described herein again.
The following describes an implementation flow of the system supporting at least two conditional handover attempts with reference to fig. 2.
As shown in fig. 2, the implementation flow includes:
step S11: the source node sends handover request information to one or more target nodes.
Step S12: and the target node feeds back a switching confirmation message to the source node.
Step S13: and the source node sends the configuration information of the condition switching to the UE.
Step S14: after receiving the configuration information of the condition switching, the UE continuously evaluates whether the candidate cell meets the condition, and after meeting the condition, the UE selects a corresponding configuration information to start the subsequent process.
It should be noted that, in the process performed in step 3 and step 4, the terminal may start one or more timers (e.g., t30x) for detecting the final condition switching result and zero or at least one counter (e.g., N3xx) for detecting the final condition switching result, and the starting time of the timers and the counter may be one of the following cases:
a. a time when configuration information of conditional handover of at least one candidate cell is received;
b. the time of applying the configuration information of the conditional handover of at least one candidate cell;
c. and triggering the time of the conditional handover after evaluating that at least one candidate cell satisfies the conditional handover.
For the above-mentioned timer, a single case may be one of the following configurations, and a plurality of cases may include, but are not limited to, any combination of the following configurations, and for each type of timer, a plurality of cases may also be activated:
1. the timer is configured for one UE, and can be used for detecting the final condition Handover failure (HOF), and the timing is not stopped when the single condition Handover failure occurs; the method can also be used for detecting single condition switching failure, and after the timer is overtime and the single condition switching failure occurs, a new condition switching is initiated and the timer is reset.
2. The timer is configured for one command, that is, there is an independent timer for each configuration information of conditional switch, and the timing duration of the timers of the configuration information of different conditional switches may be the same or different.
3. The timer is configured to be used for configuration information of a plurality of conditional switches, that is, configuration information of a plurality of conditional switches shares one timer, for example, the timer may be used for detection of a single conditional switch failure, after the timer is expired and the single conditional switch failure occurs, a new conditional switch is initiated, and the timer is reset.
For the above-mentioned counter configuration to be used for one UE, i.e. one counter per UE application. This counter can be used for final detection of the HOF, and the counter count value is +1 in case of single conditional switch failure.
In addition, when a timer (e.g., t30x) for HO failure runs, at least one of the following actions is performed:
after a target main cell is detected, starting measurement of a Radio Link Monitoring (RLM), and prohibiting starting of a timer of the RLM by adopting an RLM counter;
upon receiving the random access procedure failure indication, not triggering an infinite link recovery procedure (e.g., RRC connection re-establishment);
triggering a radio link failure when receiving an indication that the RLC reaches a maximum number of retransmissions;
wherein the target primary cell comprises a primary cell of a primary cell group and a primary cell of a secondary cell group.
The RLM counter includes a synchronous counter (e.g., N310) and an asynchronous counter (e.g., N311), and the RLM timer may be t 310.
The subsequent process includes at least one of:
applying first conditional switch configuration information, wherein the first conditional switch configuration information is conditional switch configuration information meeting a switch condition;
deleting at least one second conditional switching configuration information, wherein the second conditional switching configuration information is the conditional switching configuration information except the first conditional switching configuration information in the conditional switching configuration information;
stopping the evaluation of whether the switching condition in the at least one second conditional switching configuration information is fulfilled;
and initiating an access process in the selected target cell.
Step S15: and the UE initiates an access process to the selected target cell.
At this time, the UE can acquire the timing duration of the timer, and for the single condition switching process, if the condition switching is successful before the timer is overtime (the timing duration does not reach a first preset threshold), the timer is controlled to stop timing; and if the timer is overtime (the timing duration reaches a first preset threshold), determining that the conditional switching fails.
Wherein, when the UE judges that at least one of the following conditions is satisfied, it is determined that the condition switching is successful:
successfully accessing the target cell;
successfully receiving the physical downlink control channel PDCCH transmission scrambled by the cell radio network temporary identifier C-RNTI;
successfully applying the configuration of the target cell issued by the base station (e.g., the UE-specific signaling of the target cell);
successfully applying system information (e.g., at least one of system messages SIB1 and SIB2 of the target cell) broadcast by the base station;
the terminal assistance information requested by the base station (e.g., UE assistance information sent to the target cell) is successfully sent.
Further, if a single conditional handover failure occurs, the UE selects a configuration (e.g., another target cell configuration) from the target cell configurations satisfying the trigger condition to initiate the conditional handover procedure again, and resets the timer for the single handover (if a timer is configured for each new single conditional handover procedure) or restarts a timer (if a timer is configured for the new conditional handover procedure independently).
For the timer or counter used to detect the detection of the final HOF:
1. if the timer for final HOF detection is started and only started, the conditional handover process is successfully completed before the timeout of the timer, the timer stops timing, the conditional handover is not successfully completed before the timeout of the timer, the HOF is triggered after the timeout of the timer, and the final handover fails.
2. If the counter for the final HOF detection is started and only started, the conditional handover procedure is successfully completed before it reaches the maximum value, the counter stops counting, the conditional handover is not successfully completed before it reaches the maximum value, the HOF is triggered after the counter reaches the maximum value, and the final handover fails.
3. If the timer and counter for the detection of the final HOF are started at the same time, and the conditional switch procedure is successfully completed before the timer times out and the counter reaches the maximum value, the timer and the counter are stopped.
