ABSTRACT:
A method of operating a cellular telephone system includes detecting that a first telephone call to a cellular telephone cannot be completed due to a lack of wireless connection to the cellular telephone. The method further includes detecting that the cellular telephone is re-connected to the system. In response to detecting that the cellular telephone is re-connected, data is sent to the cellular telephone, the data being indicative of the first telephone call. The method also includes storing the data in a missed call list in the cellular telephone.
