scope:

As smartphone devices have proliferated, the capability of these terminals has also improved far more than before. Moreover, big data may improve the performance of huge-volume data collection and analysis on access/network profiles. Since access discovery and selection require both terminal and network parts to be involved, there are two distinct methods to exchange the details of access and user preferences.

The principle to estimate a solution has two aspects:

1) cost: Is it less expensive?

2) experience: Is it better?

As cost is a key attribute for users to choose access, network selection depends on information such as location and subscriber policy, as well as price policy of the access. For example, when a person enters a coffee shop, they may prefer free access. However, this kind of selection refers to user location where the access is deployed separately; only users can acquire the complete access list dynamically. On the other hand, access providers can set the price policy and confirm the authorization status of a subscribers' access to the service.

The experience issue also needs to consider two parts:

1) personal requirements, such as high speeds for gaming or high bandwidth for video;

2) network status, such as whether there is congestion, or whether it requires complex authentication methods like extensible authentication protocol - subscriber identity module (EAP-SIM).

Before starting the access selection process, there are some information asymmetries between a user and an unknown network. Multiple accesses provide various choices for access selection. The intelligent solution would meet several requirements, such as: less user intervention, less user training, less service interruption, less access congestion and lower cost.

This Recommendation describes scenarios, requirements, unified registration solutions, and other aspects such as security and pricing for intelligent access selection in multi-connection. See also [ITU- T.Y.2251].
