Abstract: Apparatus, and an associated method, for determining an allowable packet size of data packets communicated by a mobile host to a correspondent host. Path MTU discovery is performed at a network-based proxy on behalf of the mobile host. Once the path MTU is determined, an ICMPTv6 message is sent to the mobile host to inform the mobile host of the allowable packet size.

Abstract: A system is provided that includes a network entity, such as a packet data switching node (PDSN), and a terminal capable of establishing a data-link connection with the network entity, such as after setting up a physical-layer connection with the network entity. After the data-link connection is established, the network entity and the terminal can configure a network-layer protocol such that data formatted in accordance with the network-layer protocol can thereafter be sent between the terminal and the network entity over the data-link connection. Then, during configuration of the network-layer protocol, the terminal can discover at least one service available to the terminal by receiving, from the network entity, a listing of the at least one available service. The listing of each available service includes an address of a provider of the available service and a port number and/or pathname for accessing the service at the provider.

Abstract: Provided are improved systems and methods for establishing dynamic Home Agent (HA) addresses and Home Addresses (HoA) for mobile stations operating on Foreign Networks according to the Mobile IPv6 standard, thereby providing the ability to dynamically assign IP addresses for mobile stations within a Home Network rather than using static or pre-provisioned IP addresses. The present invention provides new Type 7 Router Solicitation and Type 8 Router Advertisement messages to modify the existing Mobile IPv6 standard. The Type 7 and Type 8 messages enhance Mobile IPv6 to permit a mobile station in a Foreign Network to obtain through the Foreign Network a dynamically assigned Home Agent (HA) address and Home Address (HoA) from the Home Network for the mobile station.
