Embodiment Construction

[0063] The core of the invention is to discard the repeated segmented data blocks during the system switching process. In specific implementation, the terminal may discard segmented data blocks that have not received complete data packets from the source cell during the execution of the handover, or the terminal may discard duplicate data blocks received from the target cell during the execution of the handover, and in addition , it may also be that the terminal notifies the target cell of the received data information through signaling interaction with the target cell, and the target cell discards repeated segmented data blocks when sending data packets.

[0064]In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0065] Referring to Fig. 1, Fig. 1 has shown the principle of the first embodiment of ...

Abstract

The method comprises: after cutting off the connection with the source cell, the terminal discards the invalid segmented data blocks; or after establishing a connection with the destination cell, both terminal and destination cell discards the invalid segmented data blocks in the switching process. The invention also reveals a system and a terminal thereof.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, system and terminal for data processing during handover. Background technique [0002] In order to make the wireless access technology of 3GPP (The 3rd Generation Partnership Project, the third generation mobile communication standardization partner project) have a favorable position in the environment of fierce competition of mobile communication technology in the future, it is necessary to consider the long-term evolution of the 3GPP wireless access technology. The goal of Long-Term Evolution is to develop a framework for wireless access technologies characterized by high data rates, low response times, and optimal packet access. Therefore, the important parts that need to be studied in long-term evolution include: reducing response time, higher user data rate, improved system capacity and coverage, etc. Among them, during the switching process of the ...
