<p>The embodiments of the invention disclose a control method, a device and a communication system of a direct tunnel. The embodiments of the invention determine whether to enable a direct tunnel according to network topology information by first obtaining the network topology information. For instance, when the connection status between a Radio Network Controller (RNC) and a Gateway General packet radio service Support Node (GGSN) is normal, the direct tunnel is enabled. Compared with the prior art, since the scheme uses factors relating to establish a direct tunnel, such as dynamic network topology information, as the conditions for enabling a direct tunnel, the scheme can control whether to enable a direct tunnel more flexibly and effectively.</p> |
