Systems and methods for identifying applications on a communications device

A system, comprising:

• a processor;
• and
• a computer-readable medium comprising computer-executable instructions that, when executed by the processor, cause the processor to perform operations comprising:
• receiving a message sent by the wireless communication device, wherein:
• the message comprises a feature tag corresponding to each internet-protocol-multimedia-system application present at a memory of a wireless communication device;
• and
• the feature tag corresponding to each application is associated with a feature tag status value to indicate whether the application should be registered with a communication system according to a routine selected from a group consisting of:
• the application should be registered if a corresponding wireless communication access type is a first wireless communication access type and should not be registered if the corresponding wireless communication access type is not the first wireless communication access type;
• and
• the application should be registered if a current wireless communication network being used by the wireless communication device is a home network for the wireless communication device and should not be registered if the current wireless communication network is a roaming network for the wireless communication device;
• and
• executing, in connection with each application, based on the feature tag corresponding to the application, and depending on whether the application is presently registered with the communication system, an action selected from a group consisting of:
• re-registering, to the internet-protocol-multimedia-system server, the application being already registered with the internet-protocol-multimedia-system server;
• and
• de-registering, from the internet-protocol-multimedia-system server, the application registered with the internet-protocol-multimedia-system server.

A computer-readable storage device comprising computer-executable instructions that, when executed by a processor, cause the processor to perform operations comprising:

• receiving a message sent by the wireless communication device, wherein:
• the message comprises a feature tag corresponding to each internet-protocol-multimedia-system application present at a memory of a wireless communication device;
• and
• the feature tag corresponding to each application is associated with a feature tag status value to indicate whether the application should be registered, re-registered, or de-registered with a communication system according to a routine selected from a group consisting of:
• the application should be registered if a corresponding wireless communication access type is a first wireless communication access type and should not be registered if the corresponding wireless communication access type is not the first wireless communication access type;
• and
• the application should be registered if a current wireless communication network being used by the wireless communication device is a home network for the wireless communication device and should not be registered if the current wireless communication network is a roaming network for the wireless communication device;

• and
