摘要： A method and apparatus for preventing a user equipment (UE) from forming of a routing loop in a network. The method includes maintaining a list of one or more home addresses associated with the user equipment (UE), in which each home address has been previously associated with the user equipment (UE) by a corresponding packet data network gateway (PDN GW). In response to a request to update a care-of address in a binding cache entry of a packet data network gateway (PDN GW) in the network, the method further includes comparing an address to be used to update the care-of address with the one or more home addresses in the list. If the address to be used to update the care-of address matches a home address in the list, then the update is rejected.

摘要： A method and apparatus for routing packets from a home agent to a user equipment through a first access network and a second access network. The method includes sending a first binding update message from the user equipment over the first access network to create a first binding cache entry at the home agent. The user equipment uses a home address assigned to the user equipment as a source IP address of the first binding update message. The method further includes sending a second binding update message from the user equipment over the second access network to create a second binding cache entry at the home agent. The user equipment receives packets from the home agent through the first access network and the second access network based on the first binding cache entry and the second binding cache entry.

摘要： A media access gateway includes a wireless network interface, a tunneling module, a proxy mobility agent module, and an address assignment module. The wireless network interface establishes a link with a wireless terminal. The tunneling module establishes tunnels with first and second local mobility anchors, associated with first and second packet data networks, respectively. The proxy mobility agent module stores a mapping of assigned addresses to local mobility anchor identifiers. The proxy mobility agent selects a first or second local mobility anchor in response to the mapping and a source address of the wireless terminal, and the tunneling module tunnels the packet to the selected local mobility anchor. The address assignment module transmits an address assignment message, which includes the first assigned address and a prefix usage indicator, to the wireless terminal. The first assigned address includes a network-based or client-based mobility address according to the prefix usage indicator.
