Specific implementation mode

The signal of SC, the technology that can not carry out data transmission can not be detected in order to solve UE existing in the prior art then Problem, the embodiment of the present invention propose a kind of processing method and system of data transmission exception, macro base station, wherein this method packet It includes：Macro base station MC receives the examining report that user equipment or the first micro-base station SC are sent, and examining report is user equipment and the Detected report when data transmission exception between one micro-base station SC；MC selectes communication node again according to examining report To substitute the first micro-base station SC, communication node is the second micro-base station SC for user device configuration, alternatively, being MC.

Technical solution of the present invention is described in detail below by attached drawing and specific embodiment, it should be understood that the present invention Specific features in embodiment and embodiment are the detailed description to technical solution of the present invention, rather than to the technology of the present invention side The restriction of case, in the absence of conflict, the technical characteristic in the embodiment of the present invention and embodiment can be combined with each other.

Embodiment one：

In embodiments of the present invention, it is proposed that a method of processing data transmission exception.

Specific implementation process please refers to Fig. 2.

S201, macro base station MC receive the examining report that user equipment or the first micro-base station SC are sent.

S202, MC select communication node to substitute the first micro-base station SC as user device transmissions again according to examining report Data.

MC can also select to replace other than examining report with reference to information such as UE measurement report, the network loads sent For node.

Specifically, in the implementation process of S201, examining report is for informing MC user equipmenies and the first micro-base station SC Between data transmission exception.

The specific source of the examining report is described below.

And first, before the examining report that MC receives that user equipment is sent, MC can establish radio resource with user equipment RRC connections are controlled, shunting service is provided simultaneously for user equipment with the first micro-base station SC.

Later, user equipment (UE) and the first micro-base station SC can be according to the DRX of the first micro-base station SC（Discontinuous Receiving/transmitting, it is discontinuous to receive）Configuration, into DRX mode.

And after entering DRX mode, the case where will appear data transmission exception between UE and the first micro-base station SC, specifically , there are following several abnormal conditions：

The first：

Data transmission exception between user equipment and the first micro-base station SC, specifically includes：

After user equipment and the first micro-base station SC enter DRX mode, under the downlink signal quality of the first micro-base station SC Drop to the first threshold value of setting.

The first threshold value herein can be specifically arranged by MC, or the other modes such as agreement regulation.

Because after UE and the first micro-base station SC enter DRX mode, UE will continue to examine the downlink signal of SC It surveys, and can be by testing result real-time report to MC.

If UE detects that the downlink signal quality of SC drops to certain thresholding at this time, then UE can use media The control element MAC CE of access control layer, or use RRC（Radio Resource Control, wireless heterogeneous networks）Letter It enables, or MC is notified using physical layer signaling etc., MC is allowed to know the data transmission between user equipment and the first micro-base station SC It is abnormal.

Second：

Data transmission exception between user equipment and the first micro-base station SC, specially：

In user equipment after DRX mode is switched to continuous reception pattern, user equipment can't detect the first micro-base station The downlink signal of SC.

It is configured according to the DRX of the first micro-base station SC, UE and the first micro-base station SC enter after DRX mode, and UE can be from the It is waken up in the DRX mode of one micro-base station SC, is switched to continuous reception pattern.

And DRX mode is entered in UE and the first micro-base station SC, until when UE is switched to continuous reception pattern, UE It is detected in the downlink signal to the first micro-base station SC always.

And after UE is switched to continuous reception pattern, UE is not in the coverage area of SC, then UE then can't detect The downlink signal of first micro-base station SC.

At this point, the examining report of UE can show the data transmission exception between UE and the first micro-base station SC, UE then can should Examining report is sent to MC.

When sending the examining report, UE can also use MAC CE, can also use RRC signaling, physical layer signaling etc. It sends.

The third：

After user equipment and the first micro-base station SC enter DRX mode, the first micro-base station SC detects that user equipment is sent out The quality of the detection signal sent drops to the second threshold value of setting.
