Method and system for data session establishment

A method for data session establishment from a mobile device comprising:

• checking whether an identifier for a first network is on a blacklist on the mobile device;
• if the first network identifier is not on the blacklist, attempting to establish a data connection with the first network, said attempting comprising performing authentication with an authentication entity of the first network;
• if the attempt to establish the data connection is unsuccessful, adding the first network identifier and identifiers of associated networks to the blacklist, the associated networks having a common authentication entity with the first network;
• and
• if the first network identifier is on the blacklist, establishing a data connection with a second network having a different authentication entity,
• wherein the first network and associated networks are associated based on information stored on the mobile device.

A mobile device configured for data session establishment with a network comprising:

• a communications subsystem;
• and
• a processor,
• wherein the mobile device is configured to:
• check whether an identifier for a first network is on a blacklist on the mobile device;
• if the first network identifier is not on the blacklist, attempt to establish a data connection with the first network, the attempt comprising performing authentication with an authentication entity of the first network;
• if the attempt to establish the data connection is unsuccessful, add the first network identifier and identifiers of associated networks to the blacklist, the associated networks having a common authentication entity with the first network;
• and
• if the first network identifier is on the blacklist, establishing a data connection with a second network having a different authentication entity,
• wherein the first network and associated networks are associated based on information stored on the mobile device.

A non-transitory computer-readable medium having executable code stored thereon for execution by a processor of a mobile device, the executable code comprising instructions for:

• checking whether an identifier for a first network is on a blacklist on the mobile device;
• if the first network identifier is not on the blacklist, attempting to establish a data connection with the first network, said attempting comprising performing authentication with an authentication entity of the first network;
• if the attempt to establish the data connection is unsuccessful, adding the first network identifier and identifiers of associated networks to the blacklist, the associated networks having a common authentication entity with the first network;
• and
• if the first network identifier is on the blacklist, establishing a data connection with a second network having a different authentication entity,
• wherein the first network and associated networks are associated based on information stored on the mobile device.
