Implementing intelligent network service functionality in a network

A non-transitory computer-readable storage medium storing instructions that, when executed by a processor of a mobile terminal in a network system, cause the processor to perform:

• identifying that the network system does not support an intelligent network (IN) trigger infrastructure that can originate and terminate IN triggers;
• in response to identifying that the network system does not support IN triggers, generating a simulated IN trigger by an IN simulator application deployed on the mobile terminal, wherein the simulated IN trigger comprises call routing information;
• and
• sending the simulated IN trigger from the mobile terminal to a gateway server in the network system.

A mobile terminal in a network system, the mobile terminal comprising:

• a processor that, when executing instructions stored in an associated memory, configure the processor to:
• identify that the network system does not support an intelligent network (IN) trigger infrastructure that can originate and terminate IN triggers;
• in response to an identification that the network system does not support IN triggers, generate a simulated IN trigger by an IN simulator application deployed on the mobile terminal, wherein the simulated IN trigger comprises call routing information;
• and
• send the simulated IN trigger from the mobile terminal to a gateway server in the network system.
