<p>Embodiments of the present invention disclose a method for communicating between Serving GPRS Support Nodes (SGSNs), applicable to a mobile communication network where multiple SGSNs supporting different IP versions coexist. The method includes: assigning, to an SGSN, IP addresses of all IP versions supported by the SGSN, detecting the IP version of a destination SGSN when a source SGSN initiates communication to the destination SGSN, and communicating with the destination SGSN using the IP version supported by both the source SGSN and the destination SGSN according to a detection result. Through the embodiments of the present invention, the communication between SGSNs supporting different IP versions is realized and the compatibility of networks is thus improved.</p> |
