Problems solved by technology

[0003] However, if an abnormal situation occurs that makes the UE unreachable, for example, the UE signal is blocked for a short time, and the base station fails to page the UE, the base station may notify the CN, and the CN will page the UE
However, at this time, the UE is in the deactivated state (the UE thinks that it should not receive the paging message from the CN), and the state of the UE recorded by the base station and the CN side may be inconsistent, which may lead to abnormal behavior of the UE and cannot receive data normally.

Embodiment 1

[0153] In this embodiment, both the CN and the UE configure the UE state to be idle, and the gNB (5G base station) obtains UE data from the anchor gNB. The process is as follows Figure 5 shown, including:

[0154] Step 1: The anchor gNB fails to find the UE in the paging area on the RAN side, then the anchor gNB deletes the retained context of the UE, deletes the CN connection of the UE, and notifies the CN that the UE is unreachable, for example: the anchor gNB sends UE Context release message to CN;

[0155] Step 2: After receiving the notification, the CN sets the UE state to idle state, and sends a paging message in the tracking area to find the UE;

[0156] Step 3: Under normal circumstances, the UE in the deactivated state will only receive the paging message sent by the gNB. If the UE receives the paging message sent by the CN, it will know that an exception has occurred, and the UE will set its state to the idle state ;

[0157] Step 4: The UE initiates the connect...

Embodiment 2

[0161] In this embodiment, the CN and the UE configure the UE state to be idle, and the anchor gNB uploads UE data to the CN. The process is as follows Figure 6 shown, including:

[0162] Step 1: The anchor gNB fails to find the UE in the paging area on the RAN side, then the anchor gNB deletes the reserved UE context, deletes the CN connection of the UE, and notifies the CN that the UE is unreachable, for example: the anchor gNB sends the UE context Release the message to CN; at the same time, the anchor gNB uploads the saved UE data to CN;

[0163] Step 2: After receiving the notification, the CN sets the UE state to idle state, and sends a paging message in the tracking area to find the UE;

[0164] Step 3: Under normal circumstances, the UE in the deactivated state only receives the paging message sent by the gNB. If the UE receives the paging message sent by the CN, it will know that an exception has occurred, and the UE will set its state to the idle state;

Embodiment 3

[0168] In this embodiment, the CN and the UE do not change the current UE state, and the base station sends data to the UE. The process is as follows Figure 7 shown, including:

[0169] Step 1: The anchor gNB fails to find the UE during paging in the paging area on the RAN side, and then notifies the CN that the UE is unreachable, for example: the anchor gNB sends a UE unreachable indication message to the CN;

[0170] Step 2: After the CN receives the notification, it does not delete the CN connection of the UE, nor does it change the state of the UE. Send a paging message in the tracking area to find the UE, which carries the abnormal reason, such as the RAN side in the deactivated state is unreachable;

[0171] Step 3: After receiving the paging message sent by the CN, the UE in the deactivated state does not change the UE state configuration, that is, it remains in the deactivated state;

[0172] Step 4: The UE initiates a connection activation process, which carries th...

Abstract

The embodiment of the invention provides a deactivated UE exception handling method and device and a computer readable storage medium, and the method comprises the steps: receiving a paging message sent by a core network, and determining occurrence of an exception based on the paging message; Initiating a connection recovery process; and after the connection is recovered, receiving the data of theUE sent by the network side.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, and in particular to a method, device and computer-readable storage medium for abnormal processing of a deactivated user equipment (UE). Background technique [0002] When the UE in the 5G system is in the deactivated state, there is no radio resource control (RRC) connection between the UE and the base station, but the base station still retains the UE context, and the behavior of the UE on the radio access network (RAN) side is similar to the idle state, while the core The network (CN) is still in the connected state. At this time, if downlink data arrives, the CN does not trigger the paging process, but sends the data to the base station, and the base station pages the UE, and the UE initiates a connection establishment process. [0003] However, if an abnormal situation occurs that makes the UE unreachable, for example, the signal of the UE is blocked for a short time, a...
