eap Mailing List: RE: NETSEL Issue: Terminology issues

[Bari, Farooq (farooq.bari]

As a start, my understanding of how 3GPP has been using similar terms is as follows

 

1.       Network Selection: selection between the operators/ISPs

2.       Access Technology Selection: selection between access technologies like 802.11, UMTS etc

3.       Domain Selection: selection between e.g. circuit switched voice and SIP based IMS for voice delivery

 

We can of course choose to define them differently.
