主权项 1. A method performed for facilitating rapid handoffs in a mobile network between access points, comprising: receiving, by a first access point, at least one service availability advertisement, wherein the at least one service availability advertisement includes an Internet Control Message Protocol Router Discovery Protocol (IRDP) message; extracting, by the first access point, service availability content from the at least one service availability advertisement; appending, by the access point, the service availability content into at least one rapidly repeated management packet transmission, wherein the appending of the service availability content into at least one rapidly repeated management packet transmission includes generating a new field in a management frame of the management packet, the new field being populated with the IRDP message; and transmitting, by the first access point, the appended rapidly repeated management packet transmission, the appended rapidly repeated management packet including the IRDP message being transmitted more frequently than the at least one service availability advertisement is received; receiving, by the second access point, the appended rapidly repeated management packet transmission, such that a Layer 3 handoff occurs.
