Method and apparatus for detecting subscriber service address change

A computer-readable medium having stored thereon a plurality of instructions, the plurality of instructions including instructions which, when executed by a processor, cause the processor to perform steps of a method for detecting a service address change in a communication network, comprising:

• receiving a plurality of location management messages from an endpoint device in said communication network;
• detecting an occurrence of a power cycle or a reboot event based on said plurality of location management messages for said endpoint device, wherein said detecting comprises:
• recording a timestamp associated with each of said plurality of location management messages;
• and
• detecting said occurrence of said power cycle or said reboot event if a difference in time for successive location management messages is greater than a predefined threshold;
• and
• determining that a service address change is detected for said endpoint device based upon said occurrence of said power cycle or said reboot event being detected.
