Embodiment 1
[0041] In order to solve the technical problems such as the interruption of data transmission in the UM mode in the existing E-UTRAN, this embodiment is expected to provide a method for user plane reinitialization, which is applied to the UM mode, such as figure 1 As shown, the method of this embodiment includes the following steps:
[0042] Step S101: the eNB monitors the sending status of its own HARQ information;
[0043] Step S102: When the number of consecutive failed retransmissions of HARQ information exceeds a set threshold, control the user plane on the eNB to reinitialize.
[0044] Since there is no information feedback function in the UM mode, in order to achieve the correctness of the data, a set threshold can be set. The set threshold is used to limit the number of consecutive retransmission failures of HARQ information, which is used to ensure that the eNB side The user plane is reinitialized.
[0045] The eNB in this embodiment monitors the transmission status of its ...
Embodiment 2
[0057] This embodiment provides a method for user plane reinitialization, which is applied to UM mode, such as image 3 As shown, the method of this embodiment includes:
[0058] Step S201: UE monitors its own HARQ information transmission status;
[0059] Step S202: When the number of consecutive failed retransmissions of HARQ information exceeds a set threshold, control the user plane on the UM side to reinitialize.
[0060] Specifically, the UE monitoring its own HARQ information transmission status in step S201 includes:
[0061] Step S2011: Set a continuous failure variable, and set the continuous failure variable to 0;
[0062] Step S2012: The MAC entity on the UE side detects the HARQ information sent to the eNB. If no confirmation information of successful transmission is detected from the HARQ information, and the number of HARQ retransmissions exceeds the maximum number of retransmissions, the continuous transmission failure variable Value plus one; otherwise, continue to det...
Embodiment 3
[0066] This embodiment is a device for user plane reinitialization provided on the basis of the method of embodiment 1, which is applied to UM mode, such as Figure 4 As shown, the device includes:
[0067] The first information monitoring unit 301 is configured to monitor the transmission status of HARQ information at the eNB;
[0068] The first user plane initialization unit 302 is configured to control the user plane on the eNB side to reinitialize when the number of consecutive failed retransmissions of HARQ information exceeds a set threshold.
[0069] Specifically, the first information monitoring unit 301 includes:
[0070] The first state monitoring module 301 is used to set the continuous failure variable and set the continuous failure variable to 0; detect the HARQ information sent by the UE, if the confirmation information of the successful transmission is not detected from the HARQ information, and HARQ If the number of retransmissions exceeds the maximum number of retrans...
