Patent number: 8909261Abstract: A wireless communications device dynamically determines a number of wireless network parameters prior to data transfer to increase network efficiency and decrease delays during the transmission of a multimedia messaging service message. Before sending a multimedia messaging service message, a number of wireless network parameters are dynamically determined by the wireless communications device. Based upon these determined wireless network parameters, the wireless communications device determines an optimal file transmission size. The multimedia messaging service message may then be divided into one or more file chunks having a file size equal to the optimal file transmission size by the wireless communications device. The file chunks are transmitted by the wireless communication device to another wireless user.Type: GrantFiled: December 16, 2008Date of Patent: December 9, 2014Assignee: Sprint Communications Company L.P.Inventors: Piyush Upadhyay, William James Routt, John Chandler Witzgall, Debashis Haldar, Jennifer D'Souza
