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.

Dynamic determination of file transmission chunk size for efficient media upload

A method, system, and medium are provided for suppressing a Short Message Service (SMS) induced Denial of Service (DoS) attack on a telecommunications network. A register is updated to include information relevant to SMS messages that are requested to be communicated by way of a wireless telecommunications network. The register includes information of the location where the target devices of SMS messages are located. The register is utilized to detect an SMS induced DoS attack. A trigger is communicated to an SMS router to enable a DoS mode that restricts the communication of SMS messages. In an exemplary embodiment, only those SMS messages identified as part of the DoS attack are restricted.

Detection and suppression of short message service denial of service attacks

A system, method, and computer-readable media are described for allowing a user to specify a desired time of delivery for a message (e.g., MMS message, SMS message). In one embodiment, a user interface is provided that allows the user to set a desired time of delivery while composing the message. The desired time of delivery is then included in the message. The recipient device places the message in a hidden folder until the desired time of delivery. Also, a messaging center may wait to deliver a messaging-waiting notification to the recipient until a low network usage period.

Delayed display of message

Disclosed herein is a method for data communication between a wireless-communication system and one or more wireless-communication devices. The wireless-communication system broadcasts a standard pilot signal over a pilot channel. The method comprises (a) the wireless-communication system transmitting a first broadcast-mode message in a coverage area of the wireless-communication system, wherein the first broadcast-mode message indicates that the wireless-communication system will be operating in an alternative broadcast mode, and (b) the wireless-communication system operating in the alternative broadcast mode. Operating in the alternative broadcast involves (i) generating a modified pilot signal comprising the standard pilot signal and a data message inserted in the standard pilot signal and (ii) broadcasting the modified pilot signal via the pilot channel, which enables a wireless-communication device receiving the modified pilot signal to extract the data message therefrom.
