Mechanism one: UE is reported to network side, please refers to Figure 12.

Step 1:UE sends number of failure report messages to network side, which includes information relevant to link failure, until Less include one of following information:

One, the reason of failure information occurs for UE, which includes at least one in above-mentioned cause information 1 and/or cause information 2 A cause information；

Two, to UE using the relevant information of SUL, which can be one of at least following information:

1, UE uses the instruction information of non-SUL, and one embodiment is that instruction UE is using non-SUL, another implementation Example is that the instruction information indicates UE during judging failure, which is using non-SUL；Another embodiment is that this refers to Show that information indicates that UE generation is unsuccessfully because using caused by non-SUL；Another embodiment is that the instruction information indicates that UE exists Determine that moment UE when failure is using non-SUL；

2, UE uses the instruction information of SUL, and one embodiment is that instruction UE is using SUL, another embodiment is to be somebody's turn to do Indicate that information indicates UE during judging failure, which is using SUL；Another embodiment is that the instruction information indicates UE generation is unsuccessfully because using caused by SUL；Another embodiment is, which indicates that when determining failure of UE A moment UE is using SUL；

3, UE uses the instruction information of SUL and non-SUL, and one embodiment is that instruction UE is using SUL and non-SUL, Another embodiment is that the instruction information indicates UE during judging failure, which is using non-SUL and SUL；It is another A embodiment is that the instruction information indicates that UE generation is unsuccessfully because using caused by non-SUL and SUL；Another embodiment For the instruction information indicates that moment UE of the UE when determining failure is using non-SUL and SUL.

For example, if in the information that UE is reported including: 1) random access problems；With 2) UE in the instruction using SUL Information, then it represents that UE generation is unsuccessfully because failure has occurred when carrying out random access on SUL；If on further example UE It include: the number of retransmissions of 1) UE rlc layer in the information of report has been more than the maximum retransmission of rlc layer；SUL is being used with 2) UE Instruction information, then it represents that UE occurs to be unsuccessfully to be more than because occurring the number of retransmissions of rlc layer when being communicated using SUL The maximum retransmission of rlc layer.

" the reason of failure information occurs for UE " and " using the relevant information of SUL to UE " can also use one in addition, above-mentioned Instruction information indicates, i.e., one instruction information indicates the two information.

In this step, UE to network report can there are two types of may:

After possibility 1:UE fails, a cell (cell 2) is reconnected to, which may be with UE The cell (cell 1) for receiving service when failure is different, and in one embodiment, cell 1 is in different bases from cell 2 The different distributions unit or same base for the perhaps same base of standing.Base station where from UE to cell 2 reports above- mentioned information；Or Person UE reports above- mentioned information to the distribution unit of 2 place base station of cell, and then the distribution unit is again to the centralized unit of the base station Report above- mentioned information；

After possibility 2:UE fails, UE is also protected with another distribution unit of another base station or the same base station Hold connection (as soon as UE is communicated before failure occurs with two base station communications or with two distribution units of base station), UE to The base station of connection is still kept to report above- mentioned information；Or UE reports above-mentioned letter to the distribution unit for the base station for still keeping connection Breath, then the distribution unit reports above- mentioned information to the centralized unit of the base station again.

Optionally, before step 1, can also have step 0: base station sends failure reporting request message, the message to UE Request UE reports failure cause information；Or the centralized unit of base station sends failure reporting request message to distribution unit, then The request message is sent to UE by distribution unit.

Optionally, after step 1, there can also be step 2: receive the base station of above-mentioned " information relevant to link failure " Or base station (or centralized unit of base station) of the centralized unit of base station to where when UE generation failure sends failure notification message, it should Message includes information some or all of in above-mentioned " information relevant to link failure ", the step may receive it is above-mentioned " with The base station of the relevant information of link failure " or the centralized unit of base station are different from occurring when the base station where when failure occurs for UE.

The effect of present mechanism is that base station can be helped to determine UE used up-link carrier when failure occurs, further, The configuration parameter for the user that base station optimization base station can be helped to be serviced, reduces the probability that failure occurs.

Mechanism two: distribution unit is reported to centralized unit, please refers to Figure 13.

Step 1: distribution unit sends number of failure report messages to centralized unit, and the content in the message is that distribution unit is based on With the failure occurred when UE communication and generate, which includes information relevant to link failure, includes at least following letter One of breath:

One, UE occur failure the reason of information, the information include in above-mentioned cause information 1 and/or cause information 2 at least One cause information；

3, UE uses the instruction information of SUL and non-SUL, and one embodiment is that instruction UE is using SUL and non-SUL, Another embodiment is that the instruction information indicates UE during judging failure, which is using non-SUL and SUL；It is another A embodiment is that the instruction information indicates that UE generation is unsuccessfully because using caused by non-SUL and SUL；Another embodiment For the instruction information indicates that moment UE of the UE when determining failure is using non-SUL and SUL；

For example, if in the information reported including: 1) random access problems；Believe with 2) UE using the instruction of SUL Breath, then it represents that UE generation is unsuccessfully because failure has occurred when carrying out random access on SUL；Further example, if reported Information in include: 1) UERLC layers of number of retransmissions be more than rlc layer maximum retransmission and 2) UE in the finger using SUL Show information, then it represents that UE occurs to be unsuccessfully because the number of retransmissions for occurring rlc layer when being communicated using SUL is more than The maximum retransmission of rlc layer.

" the reason of failure information occurs for UE " and " using the relevant information of SUL to UE " can also use one in addition, above-mentioned Instruction information indicates, i.e., one instruction information indicates the two information

Optionally, before step 1, can also have step 0: centralized unit sends failure reporting request to distribution unit and disappears Breath, the message request distribution unit report information relevant to link failure；

Optionally, after step 1, can also have step 2: centralized unit sends failure reporting confirmation to distribution unit and disappears Breath, the message authentication have received the message that distribution unit is sent in step 1；Or the centralized unit of base station fails to UE When where base station (or centralized unit of base station) send failure notification message, which includes above-mentioned " related to link failure Information " in some or all of information

The effect of present mechanism is that centralized unit can be helped to determine UE used up-link carrier when failure occurs, further , the configuration parameter of base station optimization base station can be helped, configuration parameter needed for which can be service user is also possible to The configuration parameter of the cell of service reduces the probability that failure occurs.
