Abstract: An apparatus dynamically assigns external home agent (HA) for VPNs and a method for the same is proposed. The apparatus establishes VPN between an internal network and at least one external network, whereby a mobile node (MN) can roam in the external network with security. The external HA closest to the MN in the visited external network is selected for mobility management of the MN. The MN only needs to register with the same external HA when roaming in the same external network. The handoff latency and end-to-end latency for a roaming MN, therefore, could be reduced significantly. It will also not reestablish the IPsec tunnel within the same external network.

Abstract translation: 一种设备动态地为VPN分配外部归属代理（HA），并提出了一种用于VPN的方法。 该装置在内部网络和至少一个外部网络之间建立VPN，由此移动节点（MN）可以安全地在外部网络中漫游。 选择最接近访问外部网络中的MN的外部HA用于MN的移动性管理。 在同一个外部网络中漫游时，MN只需要注册到相同的外部HA。 因此，漫游MN的切换延迟和端到端延迟可以显着降低。 它也不会在同一个外部网络内重新建立IPsec隧道。

Abstract: A method and system for guaranteeing QoS between different radio networks is disclosed. The radio networks comprise a first network and a second network. The first network, operating in Diff-serv mode, comprises a user equipment (UE). The second network comprises an AAA server, a TTG, and a GGSN. In the method a request to the TTG is initialized by the UE. A first QoS parameter is mapped to an IP header by the UE, an authentication request is then sent to the AAA server. The first QoS parameter is mapped to a second QoS parameter, and a Create PDP context request is constructed with the second QoS parameter to the GGSN to request a PDP context and a GTP-U tunnel.

Abstract: A home agent (200) for registering with a serving node (400) in a home network (10) includes a packet filter module (210), an agent control module (220), and a registration module (240). The packet filter module detects a mobile registration packet transmitted from a mobile node (100) and informs the agent control module. The registration module registers with the serving node by transmitting a registration request packet when the agent control module is informed by the packet filter module. The registration request packet includes a home address field and a care-of address (CoA) field. The home address field is set to an Internet protocol (IP) address of the mobile node in the home network, and the CoA field is set to an IP address of the home agent. A registration method, a network system, and a network roaming method are also provided.
