Claim Text:
1. A method for suspension and resumption of communication transmission to a mobile node comprising the steps of: receiving a first message at a local mobility anchor from a first foreign access gateway on a first foreign network, said first message having a suspend setting, said first foreign access gateway controlling downlink transmissions to the mobile node from the local mobility anchor under a 3GPP transmission protocol, said first message prepared in response to the movement of the mobile node to a second foreign network that does not support downlink communication transmissions to the mobile node; suspending at the local mobility anchor further downlink transmissions from the local mobility anchor to the mobile node in response to receiving the first message from the first foreign access gateway controlling downlink transmissions to the mobile node; receiving a second message at the local mobility anchor from said first foreign access gateway on the first foreign network, said second message having a resume setting, said first foreign access gateway controlling downlink transmissions to the mobile node from the local mobility anchor, wherein the second message is different from a registration message from the mobile node to the local mobility anchor via the first foreign access gateway; and resuming at the local mobility anchor downlink transmissions from the local mobility anchor to the mobile node in response to receiving the second message from the first foreign access gateway controlling downlink transmissions to the mobile node.
