specific Embodiment 1

[0029] When the downlink communication is normal, the node B detects that the uplink is abnormal, and determines that the number of uplink out-of-synchronization times meets the condition for reporting the radio link failure, the node B reports the radio link failure indication to the radio network controller.

[0030] After receiving the wireless link failure indication, the wireless network controller sends a wireless link activation command to Node B. In the wireless link activation command, the wireless link identifier is filled in to report the wireless link corresponding to the wireless link failure. Road identification, the activation type is filled in as deactivation, the deactivation can be synchronous deactivation and asynchronous deactivation, if it is filled in as the synchronous deactivation, you need to specify CFN; or the radio network controller sends a wireless link to the node B In a path deletion request, the radio link identification in the radio link deletion ...

specific Embodiment 2

[0036] The network-side algorithm judges that the terminal needs to initiate a handover process based on the measurement report reported by the terminal, allocates physical resources on the new cell, informs the terminal through a physical channel reconfiguration message, and sets a waiting timer to wait for the terminal to report a physical channel reconfiguration complete message. Since the network downlink interference situation is relatively serious at this time, the terminal cannot correctly recognize the physical channel reconfiguration message issued by the network side.

[0037] The waiting timer on the network side waits for the terminal to report that the physical channel reconfiguration complete message has timed out, and sends a radio link activation command or a radio link deletion request for the old and new radio links to the Node B. The radio link activation command or In the wireless link deletion request, the wireless link ID is filled in as the old and new wirel...

specific Embodiment 3

[0043] The RLC layer of the radio network controller satisfies the reset condition and sends an RLC reset instruction to the terminal. The terminal reset response is not received, and the maximum number of times set by the system is reached. The radio network controller sends a radio link activation command for the current radio link to the node B Or wireless link deletion request. In the wireless link activation command or wireless link deletion request, the wireless link ID is filled in as the current wireless link ID, and the activation type in the activation command is filled in as deactivation. Synchronous deactivation and asynchronous deactivation can be used. If it is filled as synchronous To deactivate, you need to specify CFN and set a waiting timer.

[0044] The Node B receives the radio link activation command or the radio link deletion request, and instructs the Node B to stop transmitting power in downlink.

[0045] The terminal satisfies the radio link out-of-synchro...

Abstract

The present invention discloses a network-side rescue method for service abnormality in a third-generation communication network. The steps of the rescue method include: after the wireless network controller judges that the wireless link is abnormal, the node B stops the downlink power transmission, and makes the terminal in the downlink direction If the wireless link fails, actively search for the cell and report the cell update message to the radio network controller; the radio network controller receives the cell update message, deletes the wireless link, establishes a new wireless link, and sends a cell update confirmation to the terminal The message enables the terminal to synchronize on the new wireless link, and sends physical channel reconfiguration, transport channel reconfiguration, and radio bearer reconfiguration completion messages to the network side. According to the feature that the terminal actively reports the cell update to the network side when the downlink is out of sync, the present invention saves the call drop when the wireless environment or the network is abnormal, so that the user does not need to re-initiate the call operation, and not only improves the call drop rate index of the system , and bring convenience to users.

Description

Technical field [0001] The invention relates to the field of mobile communication, and in particular to a method for rescuing business abnormalities in the third generation (3rd Generation, 3G). Background technique [0002] At present, communication technology continues to develop, the demand for data services continues to expand, and users continue to increase. Due to abnormalities in the wireless environment or network side, such as large interference at the same frequency in the neighboring area, and the terminal moving to a weak coverage area, the carrier interference is relatively poor. Fast fading, etc., will cause the network side to detect uplink out-of-synchronization, the radio link control (RLC) layer is abnormal, and the air interface signaling terminal does not respond. This may cause inconsistencies in the data configuration of the network side and the terminal side, and normal operation cannot be performed. In the subsequent communication and message interaction, ...
