Methods and Apparatus for Load Balancing in Communication Networks

摘要

Methods and apparatus for load balancing in communication networks are disclosed. An example method to perform load balancing in a communication network disclosed herein comprises routing a registration request received for a user device in an Internet protocol multimedia subsystem network to a first call processor when the user device is registered with the first call processor and in an active call session with the first call processor, and querying a load balancer to determine whether to assign the user device to at least one of the first call processor or a second call processor when the user device is registered with the first call processor but not in any active call sessions with the first call processor.
