Abstract
A method for facilitating reselection by a wireless communication device to a first network from a second network after termination of a voice call for which a CSFB procedure was performed is provided. The method can include performing measurement of the first network while connected to the first network and performing measurement of the second network during the voice call. The method can further include determining based at least in part on one or more of the measurements that the wireless communication device is in a mobility state. The method can additionally include deriving a predicted signal quality of the first network after termination of the voice call based at least in part on the measurement of the first network and using the predicted signal quality to determine whether to release a connection to the second network and attempt reselection to the first network.
