Abstract:
An example apparatus includes a memory and a call session controller. The memory is to store a first public user identifier in association with a first nomadic service designator and a first operating mode designator, and to store a second public user identifier in association with a second nomadic service designator and a second operating mode designator. The call session controller is to determine whether a first call using the first public user identifier is eligible to be established based on the first nomadic service designator and the first operating mode designator, and determine whether a second call using the second public user identifier is eligible to be established based on the second nomadic service designator and based on the second operating mode designator.
