Before the embodiments are described in detail, abbreviations for the relevant terms referred to in this disclosure are as follows:
in the related art in the mobile communication field, in order to solve some typical drawbacks of the conventional handover (such as failure of receiving a handover command, handover to an unstable cell), conditional Handover (CHO) is introduced by the 3GPP, and a specific flow thereof is shown in fig. 1, including:
the network side downloads the spring switching command message to the UE in advance, the network side configures configuration information of a plurality of candidate cells in the conditional switching command message, the UE analyzes the configuration information of each candidate cell one by one after receiving the conditional switching command, verifies the configuration information, stores the configuration information and sends a configuration completion message to the network side; and then the UE performs measurement evaluation on the candidate cell, and when the measurement evaluation result of the candidate cell meets the condition switching condition, the UE performs switching according to the switching command received before, so that the receiving rate of the switching command can be improved by issuing the switching command in advance, the success rate of switching is improved, and the time for interrupting user data transmission due to switching failure is effectively reduced. It can be seen that after receiving the conditional handover command, the UE analyzes the configuration information of the candidate cell and verifies the configuration information, and if the verification of the configuration information of a certain candidate cell fails, how the UE processes is not specified in the 3gpp ts38.331 protocol, but only the specific implementation of the UE is noted.
It can be seen that there is no provision in the relevant protocol specification for a processing party that fails to verify the candidate cell configuration information, so that the UE has a number of possibilities and uncertainties in the processing scheme associated therewith. In some implementations, if the verification of the configuration information of a certain candidate cell fails, the UE regards the conditional handover command as invalid configuration, which may result in initiating unnecessary reestablishment of the radio connection; or, the configuration information of all candidate cells in the conditional switching command is directly discarded, so that the opportunity of one conditional switching is wasted.
In order to reduce the uncertainty of the overall condition switching scheme, the embodiment of the disclosure provides a wireless connection reconstruction method, optimizes configuration information verification and processing flow, and integrally improves the rationality of the condition switching message processing.
The present disclosure provides a wireless connection reestablishing method, as shown in fig. 2, including:

In some exemplary embodiments, the configuration information for each candidate cell includes: the method comprises the steps of conditional handover measurement configuration information, physical layer time-frequency resources and dual-activation protocol stack configuration information. Optionally, the configuration information of the candidate cell may further include other information, which is not limited to the aspects of the embodiments of the present disclosure.
In some exemplary embodiments, verifying the configuration information of the candidate cell in step 220 includes:
under the conditions that the condition switching measurement configuration information of one candidate cell is effective, the physical layer time-frequency resource is effective, and the dual-activation protocol stack configuration information is ineffective, determining that the configuration information verification of the candidate cell is successful;
and determining that the configuration information verification of the candidate cell fails under the condition that the configuration information of the conditional handover measurement of the candidate cell is invalid, or the physical layer time-frequency resource is invalid, or the configuration information of the dual-activation protocol stack is valid.

performing measurement evaluation according to the configuration information of the candidate cell which is successfully verified;
and according to the measurement result, executing the condition switching under the condition that the candidate cell which is successfully verified meets the condition switching condition.
In some exemplary embodiments, triggering the radio connection reestablishment in the case that all the configuration information of the candidate cells fails to be verified includes:
and excluding all the candidate cells, preferentially selecting the current resident cell, and sending a wireless connection reestablishment request message to a network side.
I.e. cell selection is performed, all the candidate cells are excluded, and the currently camping cell is preferentially selected.
In some exemplary embodiments, the UE triggers the radio connection re-establishment procedure as shown in fig. 4.
In some exemplary embodiments, the reconfiguration failure is caused by a reconfiguration reason carried in the radio connection reestablishment request message.
It can be seen that, by the reestablishment reason carried in the radio connection reestablishment request message, the network side can know that the configuration information of the candidate cell in the issued conditional handover command fails to verify, and then relevant configuration adjustment can be performed so as to issue the handover command again. Further processing by the network side of the reestablishment cause carried in the radio connection reestablishment request message received in this case is not limited to the aspects exemplified by the implementations of the present disclosure.
