Method for improving access network selection in the context of discontinuous coverage access networks, corresponding access controller, and corresponding multicast element

摘要

The present invention relates to a method for selecting another access network when transmitting data from a content server to a terminal in a multi access network environment comprising a discontinuous coverage radio access network.;According to the present invention, the method comprises the step of:Upon detection of a request from a network selection controller to switch from a discontinuous coverage radio access network to another access network, sending a message to an access controller of said discontinuous coverage radio access network comprising cached data informing it to forward said cached data to said another access network.
