摘要： Techniques described herein may enable a wireless cellular network to transfer a call from a packet-switched (PS) portion of the wireless cellular network to a circuit-switched (CS) portion of the wireless cellular network, in a manner that ensures that the CS network receiving the call can actually support the call. For instance, before the wireless cellular network selects RAT for the CS network for transferring a call, the wireless cellular network may identify a call type for the call (e.g., simple voice call, video call, etc.), identify a RAT for the CS network that can support the call type, and proceed to transfer the call to the CS portion of the wireless cellular network that can support the call type, thus ensuring that the call is not dropped as a result of the transfer.

摘要： 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.

摘要： An improved circuit switched fallback (CSFB) method is disclosed, in which failures following several abnormal cases not anticipated by the 3rd Generation Partnership Project (3GPP) specification are avoided. User equipment implementing the improved CSFB method demonstrate increased performance in terms of call success rate and hence provide an improved user experience and an edge over Long Term Evolution (LTE) modem competitors. The improved CSFB method can be included in the 3GPP standards for such abnormal case handling and CSFB call recovery.
