In step 210, detect that first between the first network equipment in terminal and above-mentioned multiple network equipments leads to There is RLF in letter connection.

In an implementation, terminal is after access to communication networks, can real-time detection it each during normal work Whether communication connection there is RLF.Terminal by some communicate to connect to the network equipment send data when, if data send lose It loses, can retransmit, when the continuous retransmission frequency of failure of the communication connection reaches preset threshold, then can be determined that the communication link Pick out existing RLF.At this point, the first communication connection for RLF occur can be the communication connection of carrier signaling, it is also possible to carry data Communication connection.

In a step 220, if passed through there are the second communication connection of carrier signaling in other communication connections of terminal Second communication connection sends the first communication connection to second network equipment and the notification message of RLF occurs, if terminal is other logical The communication connection of carrier signaling is not present in letter connection, then is communicated to connect to first, is attached reconstruction.

In an implementation, for terminal when establishing communication connection with DU or LTE base station, network side can be that it configures corresponding communication Connection notifies terminal for carrier signaling or carrying data.In this way, it is to hold which terminal, which can recorde in its communication connection, The communication connection that information carrying enables, which is the communication connection for carrying data.

When terminal detects that RLF occurs in the first communication connection, can be confirmed in the communication connection of other normal works is It is no that there are the communication connections of carrier signaling.If there is no the communication connection of carrier signaling, then illustrate that present terminal can not Control information is transmitted with network side, needs to rebuild the first communication connection at this time, to guarantee the normal communication of terminal.If there is holding The communication connection (the i.e. second communication connection) that information carrying enables, then currently can transmit control by the communication connection of this carrier signaling Information, the communication disruption of terminal, can not rebuild the first communication connection in order to prevent, at this point, only need to be logical by second Letter connection sends a notification message to the corresponding network equipment (i.e. second network equipment), to notify the first communication link of network side to pick out Existing RLF.If there is the communication connection of multiple carrier signalings at this time, terminal can send notice by one of communication connection Message can reduce resource occupation in this way, alternatively, can also be sent a notification message respectively by multiple communication connections, in this way may be used To improve the reliability of notification message transmission.The notification message can be RRC, and (Radio Resource Control, refers to nothing Line resources control) message.After second network equipment receives notification message, first network equipment can be notified to delete about first The configuration information of communication connection.
