Abstract
Example embodiments disclosed herein relate to implementing circuit-switched call delivery. A mobile terminating call for user equipment (UE) is received. A first mobile switching center is determined to perform a first call termination attempt for the mobile terminating call by sending a provide roaming number (PRN) request with a pre-paging supported parameter to the first MSC. The first call termination attempt can include instructing the UE to return to a CS network domain to receive the call. A message indicating that the UE is not connected to the first MSC is received. It is determined whether the UE is in a registration process within a duration of time. If the registration succeeds, a second call termination attempt for the mobile terminating call is made via the second MSC.
