1. A method for processing information applied to a first node, comprising:
receiving, by the first node, an indication message from a network side, wherein the indication message indicates a user equipment under the first node to hand over to a second node; and
negotiating, by the first node, with the second node to reserve radio link layer control protocol (RLC) status information and cached data of all bearers of the user equipment, so that the second node provides a continuing data service to the user equipment based on the reserved information,
wherein the cached data comprises cached data to be forwarded in an acknowledged mode (AM) and from the first node to the second node;
for an AM sending end, the cached data to be forwarded in the AM mode comprises: all data packets that have been sent with no ARQ ACK being received or all data packets after a first data packet that has been sent with no ARQ ACK being received, and all data packets that are not sent and are cached in a sending cache; and
for an AM receiving end, the cached data to be forwarded in the AM mode comprises: all data packets in the receiving cache.
