The policy would refer to the following information:
• access type;

• access name preference;
• authentication type;
• access status;
• relative access;
• friendly roaming list;
• price (optional).

7.3.2 Terminal-based access selection solution

Smartphones supporting multiple access methods soared in 2012, and the capability of these terminals has
also improved far more than before. Due to different access authentication requirements, users’ calls or
sessions may be sporadically interrupted. In practice, some access networks are provided by operators while
others may be built by individuals or enterprises; therefore, the handover and roaming issues have gradually
become important because the profile for each access network is set separately by its owner. Providing
access profiles may help users’ preferences in the selection of adequate accesses to properly support their
UEs, APPs, specific Operating System functionality and chipset performance.
Before a terminal selects an available connection, each network would provide a necessary access profile
with the following information:
• operator ID;
• access type;
• authentication type;
• Internet connectivity;

• pricing
• friendly operator list;
• network status.

The terminal would collect each access profile for users and then make a decision by user/terminal policy.
The terminal policy would include the extra information below:
• preferred access type;

• preferred operator type;
• preferred service type;
• preferred network access.
