Wherein, described 4th tunnel is set up response and is specifically as follows the 8th GRE message, the GRE head of described 8th GRE message can take concrete structure as shown in Figure 2, and wherein T field is identical with the information that the T field of described 5th GRE message is carried, and a low bit position M of M res field is 0.

It should be noted that described user terminal receives after described 4th tunnel sets up response, corresponding tunnel label can be distributed.After response is set up in the 4th tunnel that the described user terminal described HAAP of reception sends, the 8th list item is recorded, the information that in described 8th list item, record has described 4th tunnel to be standby tunnel on the first user table that described user terminal can also preserve on described user terminal.

In embodiments of the present invention, the execution sequence of 101,103,301 and 303 is not limited, and both successively can perform with a definite sequence, it is also possible to perform simultaneously.One preferably, sets up main fixed network tunnel, standby fixed network tunnel, main wireless network tunnel and standby wireless network tunnel successively.

By technique scheme, except establishing the main tunnel of the first kind and standby tunnel between user terminal and HAAP in the embodiment of the present invention, outside i.e. first tunnel and the second tunnel, the main tunnel of Second Type and standby tunnel are also set up, i.e. the 3rd tunnel and the 4th tunnel, wherein the tunnel of the first kind and Second Type is respectively fixed network tunnel and wireless network tunnel, therefore the embodiment of the present invention achieves and sets up two fixed network tunnels and two wireless network tunnels, wherein have and include a main fixed network tunnel, article one, standby fixed network tunnel, article one, main wireless network tunnel and a standby wireless network tunnel, propose the concept of gre tunneling protection group, tunnel failure and flow bandwidth are switched and provides reliable technical scheme support.

In superincumbent two embodiments, describe and mode is set up in main tunnel and standby tunnel, be specifically described below and how to use main tunnel and standby tunnel.First illustrate from the angle of user terminal.

In the embodiment shown in fig. 1, establishing described first tunnel and described second tunnel, wherein said first tunnel and described second tunnel is same type of tunnel, such as, be DSL tunnel or be LTE tunnel.Owing to described first tunnel is main tunnel, described second tunnel is standby tunnel, therefore when described first tunnel is normal, by described first tunneling traffic data, and when described first tunnel failure, described user terminal can be by the business datum of transmission on described first tunnel by described second tunnel transmission.

In the embodiment shown in fig. 3, establish described first tunnel, described second tunnel, described 3rd tunnel and described 4th tunnel, wherein said first tunnel and described second tunnel are same type of tunnel, described 3rd tunnel and described 4th tunnel are same type of tunnel, and described first tunnel and described 3rd tunnel are different types of tunnel.The most described first tunnel and described second tunnel are DSL tunnel, and described 3rd tunnel and described 4th tunnel are LTE tunnel.
