Indication of access technology for a proxy mobile internet protocol

摘要

A method comprising: preparing (410), by means of a mobility access gateway (320, 330, 340), an access technology indicator that indicates a type of access technology by which a mobile node connects to the gateway mobility access; sending (420), via the mobility access gateway (320, 330, 340), a link message to a local mobility entity (350) that includes the access technology indicator; and receive (430), through the mobility access gateway (320, 330, 340) from the local mobility entity (350), a prefix corresponding to a first interface through which the mobile node (310) connects to the mobility access gateway, where the prefix has been generated in response to the binding message.
