Abstract: Systems and methods of enabling access for non-emergency voice calls are described. A UE operates in a network supporting voice services via a multitude of RATs. The UE attempts to access the network via a first RAT offering voice services and data services. If the UE does not receive a response from the network within a first time period, the UE re-attempts the access to the network via the first RAT. If the number of access attempts for which the UE does not receive a response is at least a threshold value, the UE refrains during a second time period from further access attempts via the first RAT for the purpose of receiving data services, and continues to attempt access via the first or second RAT for the purpose of receiving voice services.

Abstract: The Access Network Discovery and Selection Function (ANDSF) is a function in LTE networks that an operator can use to control how UEs prioritize between different access technologies if non-3GPP access networks such as wireless local area networks (WLANs) are available and can also assist devices to discover available access networks. Schemes are described that introduce flexibility in the control of WLAN selection in roaming scenarios based on HPLMN preferences.
