Maintaining active sessions during subscriber management system maintenance activities

A subscriber management system for maintaining active communication sessions during subscriber maintenance activities is provided. The system can delay detaching mobile devices from the mobile network when there are active communication sessions that are associated with subscriber management maintenance activities or customer care activities in order to avoid disrupting the subscriber experience. The system can delay deleting the subscriber information until the active sessions have ended, which will allow the customer care activities to continue uninterrupted. In an embodiment, the subscriber management system can determine whether to detach the active communication session based on the priority of the session, such as whether it is real-time, or with a customer care element of the mobile network.
