Method and device for transferring data
First Claim
1. A method for transferring data, comprising:
- transferring data with a base station via a first link, wherein a second link is established for offloading for the first link;
transmitting, if a radio link failure (RLF) occurs on the first link, an RLF indication message to the base station, wherein the RLF indication message is used to notify the base station that the RLF occurs on the first link; and
transferring, over the second link, at least a portion of the data on the first link.

Abstract
Provided in embodiments of the present invention are a method and a device for transferring data. The method includes: transferring data to a base station via a first link, a second link offloading for the first link; if a radio link failure (RLF) occurs on the first link, transmitting an RLF indication message to the base station, where the RLF indication message is used to notify the base station that the RLF occurs on the first link; and transferring, over the second link, at least a portion of the data on the first link. According to embodiments of the present invention, when a link failure occurs between a user equipment and the base station during a mobile data offloading process, data transfer is performed via the offloading link, a time delay can be reduced and the data transfer efficiency is improved.
