Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained on the premise of creative work is not made should all belong to the scope of protection of the invention.

Currently in the content in the heart network architecture, solve the ambulant schemes of CCN and mainly realized by the transmission path by control information adjustment interest bag and packet.For example, terminal is currently connected with a certain base station, if terminal request content, the interest bag for asking the content is then sent to the base station, after base station receives the interest bag and parsed, first matched with the base station Slow contents deposited itself, corresponding packet is sent to terminal if the match is successful；The interest is forwarded a packet into corresponding source if matching is unsuccessful, corresponding content is returned to base station by source in the form of packet, then is transmitted to terminal by base station.

In CCN frameworks, content is divided into several content blocks, and each content blocks have its corresponding label.For example, a content is divided into 10 content blocks, label is respectively 1-10.Terminal sends 10 interest bags to base station successively when asking the content, asks this 10 content blocks respectively.This 10 interest bags are transmitted to source by base station successively, and according to this 10 interest bags, source returns to 10 packets and is transmitted to terminal to base station, then by base station successively.Therefore, the transmitting procedure of the content has delay for terminal, i.e., when terminal have sent 5 interest bags to base station, and it may receive only 2 packets of base station forwarding.If at this moment, terminal is moved, target BS is switched to from former base station, then the 3rd situation to the 5th packet that can not be received from former base station occurs.

For above-mentioned situation, in current CCN frameworks, terminal is after target BS is switched to, need to send the 3rd to the 5th interest bag successively to target BS again, and forward these interest bags from target BS to source, this make it that data transfer produces very big delay when base station is switched, and influences the experience of user.

Pin is in this regard, a kind of currently proposed improved plan.The flow of the program is as follows：Terminal is in movement if it find that target BS, when target BS will be switched to from former base station, one is sent first indicates that the message informing former base station terminal will be switched over, former base station is after the instruction message is received, stop sending packet to terminal, but do not stop its content blocks progress Slow for forwarding interest bag and the process from source received data packet, i.e. former base station to have requested that terminal but do not receive also to source to deposit.Then, Terminal sends an instruction message after completing to switch to target BS from former base station, then to target BS, notifies target BS to ask for the content blocks that Slow is deposited to former base station.

This scheme is that then content blocks deposited from target BS to former base station requests Slow, the content blocks that Slow is deposited need passive request to be just transmitted, and time availability is low after being completed in terminal switching base station.And if when the hop count between former base station and target BS is more, larger delay can be still produced, Consumer's Experience is had a strong impact on.The present invention exactly proposes solution for problem above.

It should be understood that, in embodiments of the present invention, terminal is referred to as system, subscriber unit, subscriber station, movement station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, Wireless Telecom Equipment, user agent, user's set or user equipment（UE, User Equipment ^ terminals can be cell phone, wireless phone, SIP (Session Initiation Protocol, session initiation protocol）Phone, WLL (Wireless Local Loop, WLL) stand, PDA (Personal Digital Assistant, personal digital assistant）, handheld device, mobile unit, computing device or other processing equipments for being connected to radio modem with radio communication function.
