Abstract
The present invention relates to methods and apparatus for efficient handling of registration messages by network equipment. An exemplary embodiment includes the steps of: operating network equipment in a first mode of operation; detecting that a first condition exists, switching the network equipment from said first mode of operation to a second mode of operation, said second mode of operation including: receiving a first initial SIP registration request message destined for a registrar; determining an address of record (AOR) value included in the first initial SIP registration request message; determining whether a matching registration record exists for the determined AOR value included in the first initial SIP registration request message; and when the network equipment determines that a matching registration record exists for the determined AOR value included in the initial SIP registration request message, treating said first initial SIP registration request message as a refresh SIP registration message.
