  • Method to improve the registration of in an NGN-IMS subsystem
    Patent number: 9240972
    Abstract: A method to improve the registration of “Permanently Registered Users” (User1, User2, . . . User500) in an NGN-IMS subsystem. The permanently registered users are coupled to the IMS subsystem via a group device (AGW1, IP-PBX, SIP/H.323 GW) that is registered in the IMS subsystem as a dedicated IMS virtual user by means of its IMPI/IMPU identifier. The HSS/UPSF server is then allowed to download the user profiles in bulk. This results in fewer loads on the IMS and in a shortened start-up time of the group device(s).
