  • Location-based IMS server selection
    Patent number: 9749837
    Abstract: A user location is estimated based on an IP address assigned to the user's device/equipment during registration for multimedia application services that are provided over the IP multimedia subsystems (IMS) network. The latitude and longitude information of the user location is obtained based on the IP address assigned to the user device/equipment. Such information is used to determine an appropriate server(s) for establishing an IP multimedia service session. In some embodiments, a closely located IMS server(s) is selected for proxying, interrogating, providing or delivering IP multimedia services. In this manner, each user device/equipment communicates with IMS servers that are located close to the user and thus, the geographically distributed load among the IMS gateway servers can be achieved.
