A user that is using both CS (GSM) and IMS (MMTeL) domains needs to be provided a consistent service and thus a choice has to be made as to which data model is going to be used either GSM or MMTeL, for this reason a software updating system and method are described. The system for updating communication services includes user equipment (e.g. GSM 110, 510, 610) configured to communicate using a first communication service standard (140, 530, 630) and a second communication service standard (e.g. IMS, MMTeL), a subscriber database, an application server, and a network device. The network device detects an update trigger corresponding to a user equipment, requests that the user equipment discontinue using the first communication service standard, and flags the user equipment as updated by communicating with the application server and the subscriber database, The network device also receives a communication from the user equipment and determines whether the communication corresponds to the first communication service standard or the second communication service standard. If the communication corresponds to the first communication service standard the network device communicates an error message to the user equipment. However, if the communication corresponds to a second communication service standard, the network device processes the communication. |
