Abstract:
A method for assisting a wireless communication device to return to a first network from a second network subsequent to termination of a voice call for which a Circuit Switched Fallback procedure was performed to transition from the first network to the second network for servicing of the voice call is provided. The method can include preventing transmission of a data flow for a data service after termination of the voice call. The method can further include searching for the first network while transmission of the data flow is prevented. If the first network is found, the method can additionally include reverting to the first network and servicing the data service on the first network. If the first network is not found, the method can also include remaining on the second network and servicing the data service on the second network.
