Method, System, and Device for Network Selection

A mobile equipment (ME), comprising:

• a network selection trigger module configured to trigger network selection;
• a reading module configured to read a network selection list stored in a Universal Integrated Circuit Card (UICC) and a network selection list stored in the ME after the network selection trigger module triggers network selection;
• a device management (DM) tree configured to store the network selection list stored in the ME;
• a DM client configured to configure the network selection list stored in the DM tree through a DM command sent in a DM session;
• and
• a network selection module configured to perform network selection according to the network selection lists read by the reading module.

A method for network selection, the method comprising:

• detecting whether a network selection policy trigger condition is satisfied;
• and
• when the network selection policy trigger condition is satisfied, performing network selection according to a network selection policy;
• or
• when no network is selected according to the network selection policy, reading a network selection list stored in a Universal Integrated Circuit Card (UICC) and a network selection list stored in a device management (DM) tree of a mobile equipment (ME) to perform network selection, wherein the network selection list stored in the DM tree of the ME is configured and stored through a DM command sent in a DM session.
