Method for transferring a tunnel between nodes in a gprs system

Abstract

The invention relates to a method for transferring a tunnel from a first operating node (SGSN 1 ) of a mobile radio communication system, especially a GPRS system, to a second operating node (SGSN 2 ). The mobile radio communication system comprises operating nodes (SGNS 1 , SGNS 2 ) and a gateway node (GGSN), at least one of these nodes being a node according to version 0 of the GTP protocol, and others being nodes according to version 1 of the GTP protocol. When the first operating node (SGSN 1 ) is the node according to version 0, the request to adapt the context contains IMSI and NSAPI information of the tunnel concerned in order to correctly transfer said tunnel. If the second operating node (SGSN 2 ) or the gateway node (GGSN) is a node according to version 0, the first operating node (SGSN 1 ) allocates a flow label to the context, and the second operating node (SGSN 2 ) sends the request to adapt the context of the tunnel concerned along with said allocated flow label.
