A wireless communication service system and a mobile phone are provided. The mobile phone generates a calling signal of a recipient number and determines whether a storage unit has stored a cornet associated with the recipient number. If the storage unit has stored the cornet, the mobile phone sends a transmission containing the cornet. If the storage unit has not stored the cornet, the mobile phone sends a transmission containing the recipient number. When the wireless communication service system receives the transmission containing the recipient number, the wireless communication service system determines whether the recipient number has joined a cornet cluster network of a caller number. If so, the wireless communication service system calls the cornet. If not, the wireless communication service system calls the recipient number.
