Abstract
We consider network selection for a cloud service use case.

Motivation
• Significant number of services are not local but belong in a
Cloud, globally located
– Email, video download, music streaming etc. are examples of today
– It could be envisioned that due to improved, always on, broadband cellular
connectivity and combination of IEEE802.11 technology the number of
services will further increase
• Introduction of completely new ones can be foreseen – predicting details of those
is quite impossible
• Typically there is a number of different networks available
– Each can provide connectivity to the network
• Price per bit will continue to go down
– Users are more interested in fluent and seamless connectivity and usability
of applications - no manual connectivity setup
– Users don’t know which applications require connectivity to the cloud and
when

Use Case
• User of electronic consumer device starts to use application XYZ in his
device
–
–
–
–
–
–
The application-XYZ requires connectivity to cloud services
Device has not yet associated to any network as it has not been used for while
Multiple different networks available at that location
Some networks are not accessible to the user
Multiple networks available which could be used for the connection to the cloud
Each network may differ, as for example, in terms of:
•
•
•
•
•
Supported authentication mode, e.g. WEB based or USIM based
Supported security
Available latency and throughput
Network load or coverage/mobility support
Network Operator preferences
• In the best case:
– The device is able to make a “clever” network selection, at once, so that application
can operate seamlessly with high QoE without any manual intervention of the user
• In the non successful case (which we should avoid):
– User realizes that application does not work properly and takes manual action to
select network and provide authentication credentials

Conclusions
• Connection to cloud is most of the time the service that user
desires
– User prefers connectivity without manual intervention
• Devices needs to make “clever” decisions
– ISD work could provide additional information and new means for
this “clever” decision making process
• Some of this work has been potentially done in 802.11u and
WiFi-alliance already
– Review of prior work is needed
• To get holistic views in ISD study group it is proposed to
include this use case in the use case document for future
considerations
