The claimed subject matter relates to systems and methods for processing messages in a wireless communications environment. In an aspect, a communications method is provided. The method includes initiating a registration (270,290) with a network domain node (210), which may be a Local Mobility Anchor (LMA), and generating sequence information with respect to the registration. The registration may be triggered by a communication link creation (240,284). This can take different forms, including some form of an L2 connection request, e.g., Address Resolution Protocol (ARP), Neighbor Discovery (ND), Dynamic Host Configuration Protocol (DHCP) or other protocol. The sequence information is then employed to facilitate further communications with the network domain node, in particular to prevent out of order delivery of registrations to the network domain node (210), e.g., in a condition, commonly referred to as "ping-pong". When Proxy Mobile IP is being used, the sequence data is generated by a Proxy Mobile (410) and dispatched to the access points (450,460). |
