Abstract： |
Characters of the invention are that following steps are included: when MH is about to be switched, the invention determines whether there are following situations including changes of average arrival rate of packet or average time of MH resided in AR, or MH is going to switch to AR governed by current MAP. If the said three situations do not occur, then MH uses same mobile management plan before and after switching; otherwise, MH calculates optimal MAP area coverage and minimal cost difference of each sensed MAP. Noting minimal value of minimal cost differences of all MAP is as OC. If OC is larger than 0, than MH uses MIPv6 as mobile management plan; other wise, uses HMIPv6 as mobile management plan. MAP and optimal MAP area coverage corresponding to the selected OC are as zoned mobile management entity, and MAP area coverage. The invention reduces average registered time delay, and average time delay of packet transmission. |
