Abstract:
1. A method to perform load balancing in a communication network, the method comprising: in response to receiving a first message associated with a first registration request for a user device, determining, via a logic circuit, whether the user device is currently assigned to a first call processor, the first registration request being associated with a reregistration of the user device when the user device is currently assigned to the first call processor; in response to receiving the first message, performing, via the logic circuit, a load balancing procedure to reassign the user device to one of a plurality of call processors including the first call processor, the load balancing procedure to bias reassignment to the first call processor in response to the user device being determined to be currently assigned to the first call processor; and in response to receiving a second message associated with a second registration request for the user device, causing the first call processor to de-register the user device in response to determining that the second message is associated with a pending reassignment of the user device from the first call processor to a second call processor included in the plurality of call processors.
