Methods and apparatus for controlling the presentation of user changeable IP Multimedia Subsystem, IMS, service rules at a user equipment. The service rules, conditions, and/or actions are defined within an XML document maintained within the IMS network. The XML document includes one or more informational elements identifying the service rules that the user can change, which include at least one of an unconditional or immediate based service rule. Upon receipt of the XML document, the user equipment or a web portal, interprets the informational element(s) and presents an indication in relation to whether the service rules are changeable. In response, user defined service rule information may be received and used in changing service rules associated with the user. The user defined service rule information is transmitted to the IMS network for validation and allowable portions of the user defined service rule information are used in updating the service rules. |
