Embodiment Construction

[0120] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0121] When describing the embodiments of the present invention, some concepts used in the following description are explained first.

[0122] Traditional switching procedures such as figure 1 as shown, figure 1 The process in the above method is to interrupt the data transmission on the source side first, and then continue the service transmission after connecting to the target node. Therefore, a large data interruption delay is caused.

[0123] The successful process of DAPS handover is as follows: figure 2 Shown:

[0124] Step S201-Step S205: The original data transmission link is always maintained between the source network entity (NR gNB or ng-eNB) and the user equipment (UserEquipment, UE, also called terminal); for the target network enti...

Abstract

The invention provides an information reporting and obtaining method, a terminal and network side equipment, and relates to the technical field of communication. The information reporting method is applied to the terminal, and comprises the following steps: under the condition that a dual active protocol stack DAPS switching fails, sending target information of the DAPS switching failure to network side equipment; wherein the target information is used for indicating the reason of DAPS switching failure. According to the scheme, under the condition that DAPS switching fails, the target information of DAPS switching failure is sent to the network side equipment so as to assist the network side equipment in obtaining related failure information, it is guaranteed that the network side equipment can carry out network optimization in time, and the switching success rate of the terminal is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an information reporting and acquiring method, terminal and network side equipment. Background technique [0002] The dual active protocol stack (Dual Active Protocol Stack, DAPS) handover is an optimization of the traditional handover, which can reduce the delay of service interruption during the handover. When the handover command is sent to the terminal and the handover is performed, the terminal maintains the connection with the source base station, and releases the link of the source base station until the terminal successfully accesses the target base station. If during the DAPS handover process, the terminal fails to access the target base station, but the terminal can still maintain the connection with the source base station at this time, the terminal will restore the signaling connection with the source base station, and report a failure message at the so...
