Background
Several fora work with handover issues between WLAN and WWAN
Even if it is open whether IEEE should start active work on such issues, new work items should not prevent them
Most likely it will be the terminal that takes the handover decision
The terminal need information about the link layer

3. What could be done within RRM?

What could be done within RRM?
Open up link layer specific information to upper layers
Provide an API so that upper layers can request or set specific parameters

Possible parameters
The following list of parameters (probably far from complete) may be helpful for the terminal when taking a handover decision:
Data rate
Error rate
Delay
Delay jitter
Signal strength
All parameters are relevant for max/min/average and downlink/uplink

Questions
Is the availability of such parameters at the terminal within the scope of RRM?
Is the creation of an API for setting and requesting various parameters within the scope of RRM?
Is the type of parameters listed within the scope of RRM or should they be more specific?
