Re: [802.21] Power Management over heterogeneous HO



Hi Qiaobing,
 
I am not clear on what you mean to the power assumption.  The power consumption of each radio can be measured by vendors according to the modes of shutdown, idle, sending and receiving.  MIH can measure the passing throughput of the each network interface.  The service type of traffics can be indicated by the QoS module in the network stack.
 
Thanks!

Liang,

To add a MIH primitive to query about the power consumption of the links
is not hard, but how do the heterogeneous links underneath the MIH knows
its own power assumption?
