Problems solved by technology

The current solution is that the UE needs to initiate RRC connection re-establishment when the conditions stipulated in the 3GPP protocol are met. The current solution cannot perform RRC connection re-establishment in time when there is a problem in the data transmission between the eNodeB and the UE, thus resulting in the data between the eNodeB and the UE The transmission is interrupted, resulting in dropped calls

Embodiment 1

[0086] Figure 1B It is a schematic flowchart of a method for reestablishing a radio resource control connection provided by the present invention. The method in this embodiment may be executed by a base station, as shown in FIG. 1 , the method may include:

[0087] 101. The base station detects whether the data transmission between the base station and the UE is normal;

[0088] There may be multiple ways to detect whether the data transmission between the base station and the UE is normal.

[0089] The base station can determine whether the data transmission is normal by using the retransmission ratio or bit error rate of uplink or downlink data transmission.

[0090] Optionally, if the retransmission ratio exceeds the retransmission ratio threshold, the data transmission is abnormal; or, if the retransmission ratio does not exceed the retransmission ratio threshold, the data transmission is normal.

[0091] Optionally, if the bit error rate exceeds the bit error rate thre...

Embodiment 2

[0106] figure 2 It is a schematic flowchart of a method for reestablishing a radio resource control connection provided by the present invention. The method in this embodiment can be executed by the UE. For the specific process and description, refer to Embodiment 1; figure 2 As shown, the method may include:

[0107] 201. The UE receives signaling sent by the base station, where the signaling is sent by the base station to the UE when data transmission between the base station and the UE is abnormal;

[0108] 202. The UE initiates an RRC connection re-establishment request to the above-mentioned base station according to the above-mentioned signaling.

[0109] The signaling in this embodiment is as described in the first embodiment above. Optionally, for the determination condition of abnormal data transmission between the base station and the UE, reference may be made to the description in Embodiment 1 above.

[0110] In this embodiment, when the data transmission betwe...

Embodiment 3

[0113] image 3 A schematic diagram of signaling for the method for reestablishing a radio resource control connection provided by the present invention, as shown in image 3 As shown, the method may include:

[0114] 301. The base station detects whether the data transmission between the base station and the UE is normal;

[0115] Wherein, the method of detecting whether the data transmission between the base station and the UE is normal is as described in the first embodiment

[0116] If the data transmission between the base station and the UE is normal, the base station does not perform the subsequent steps of this embodiment; if the data transmission between the base station and the UE is abnormal, the base station performs step 302 .

[0117] 302. The base station sends a physical downlink control channel order (Physical Downlink Control Channel Order, PDCCH Order) to the UE;

[0118] The signaling sent by the base station to the UE is a PDCCH ORDER, and the UE initia...

Abstract

The invention provides a method and a base station for reconstruction of radio resource control (RRC) connection. The method comprises that the base station detects whether data transmission between the base station and user equipment is normal or not; when the data transmission is abnormal, the base station sends a signal to the user equipment (UE), so that UE can carry out reconstruction of RRC connection according to the signal; and the base station receives and processes reconstruction request of RRC connection sent by the UE. The base station can actively trigger the UE to initiate the reconstruction of RRC connection when the data transmission between the base station and the user equipment is abnormal, thereby preventing interruption of data transmission and reducing influences on the data transmission.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method and a base station for reestablishing a radio resource control connection. Background technique [0002] According to the provisions of the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP) agreement, the current radio resource control (Radio Resource Control, RRC) connection reestablishment is judged and initiated by the user equipment (User Equipment, UE). The UE is in the RRC connection state, and when the UE meets the conditions stipulated in the 3GPP protocol, it initiates RRC connection reestablishment. [0003] In some scenarios, there may be problems in the data transmission between the UE and the evolved base station (Evolved NodeB, eNodeB). At this time, it is necessary to restore the wireless connection through RRC reconstruction, so as to continue to maintain the normal transmission of services between the two parties. The cu...
