Abstract: A method for setting a policy for Over-The-Top (OTT) calls in a mobile network is provided. The method includes determining whether a cell of the mobile network has at least one neighboring cell of at least one roaming partner of the mobile network, and determining a bearer policy for routing OTT calls in the cell based on whether the cell is determined to have the at least one neighboring cell of the at least one roaming partner. The determined bearer policy indicates whether the OTT calls in the cell are to be routed on a dedicated bearer or a default bearer for connecting to an Internet Access Point Name (APN).

Abstract: Implementing multiple load balancer drivers for a single load balancer is disclosed. A first request directed to a load balancer to load balance requests based on a first request selection instruction is received. A first particular load balancer driver is selected from a plurality of load balancer drivers based on a load balancer table that correlates request selection instructions to corresponding load balancer drivers of the plurality of load balancer drivers. Subsequent requests that are encompassed by the first request selection instruction directed to the load balancer are caused to be load balanced by the first particular load balancer driver.
