Method, device, and system for communicating a changeability attribute

A communication system comprising:

• at least one terminal device comprising a first terminal device, the first terminal device comprising a processor connected to non-transitory memory;
• a server that hosts a service, the server comprising a processor connected to a non-transitory computer readable medium, the server communicatively connectable to the first terminal device;
• the first terminal device configured to receive a first message from the server, the first message comprising information about a first attribute for a first feature of the service relating to a changeability of the first attribute having been changed;
• the first terminal device configured to send a second message to the server in response to the first message, the second message comprising information identifying the information about the first attribute;
• the first terminal device configured to receive a third message from the server, the third message comprising information indicating a changeability setting for the first attribute;
• the first terminal device configured to update how a user interface for the service is to be displayed in a display device connected to the first terminal device in response to the third message such that the user interface is displayable via the display device so that one of:
• (i) an identifier for the first attribute is changed from indicating the first attribute is an unchangeable attribute to indicating that the first attribute is a changeable attribute by the user via input that is entered via the user interface in accordance with the information indicating the changeability setting of the third message, and
• (ii) an identifier for the first attribute is changed from indicating the first attribute is a changeable attribute that is changeable by the user via input that is entered via the user interface to indicating that the first attribute is an unchangeable attribute that the user is not permitted to adjust in accordance with the information indicating the changeability setting of the third message.

A terminal device, the terminal device comprising non-transitory memory communicatively connected to a processor unit, the memory having an application that defines a method performed by the terminal device when the application is run by the processor unit, the method comprising:

• the terminal device sending a second message to a server that hosts a service in response to receiving a first message from the server, the second message comprising information identifying information about a first attribute for a first feature identified as having been changed in the first message;
• the terminal device updating how a user interface for a service is to be displayed in response to a third message indicating a changeability setting for the first attribute of the first feature of the service identified in the third message received from the server such that the user interface is displayable so that one of:
• (i) an identifier for the first attribute is changed from indicating the first attribute is an unchangeable attribute to indicating that the first attribute is a changeable attribute by the user via input that is entered via the user interface in accordance with the information indicating the changeability setting of the third message, and
• (ii) an identifier for the first attribute is changed from indicating the first attribute is a changeable attribute that is adjustable by the user via input that is entered via the user interface to indicating that the first attribute is an unchangeable attribute that the user is not permitted to adjust in accordance with the information indicating the changeability setting of the third message.
