Abstract:
1. A method comprising: connecting a mobile station to a first network wherein the first network is one of a client mobile internet protocol (CMIP) where the mobile station controls the IP and a proxy internet protocol network (PMIP) where the network controls the IP and wherein the mobile station can be a CMIP-enabled mobile station and is capable of connecting to a PMIP network; when the mobile station roams between a CMIP network and a PMIP network: determining if the first network provides the capability of mobility control; when the first network is determined to provide the capability of mobility control, providing a network mobility control capability announcement to the mobile station; determining if the mobile station provides the capability of mobility control; and when the mobile station is determined to provide the capability of mobility control, providing a mobile station mobility control capability announcement to the network, wherein control of mobile IP is prioritized such that when the mobile station is CMIP-enabled and is connected to a network that is PMIP-enabled mobile IP is controlled by the network, and when the mobile device is connected to a network that is PMIP-enabled and moves to another network that is PMIP-enabled, mobility control is reclaimed by the mobile device and then assigned to the another network.
