A messaging server forwards emails to mobile communication devices of users to whom the emails were respectively addressed. An antivirus server determines whether an email addressed to a user of a mobile communication device, to be forwarded by the messaging server to the mobile communication device, is infected with a virus. In response to determining the email is infected with a virus, a bulletin generator transmits, to the mobile communication devices besides the mobile communication device of the addressee of the email determined to be infected, an all points bulletin message disclosing the existence of the virus. The bulletin message is transmitted directly to, instead of via email to, the wireless mobile communication devices.

Wireless communication system congestion reduction system and method

Systems and methods for processing documents are disclosed. Documents received at a data server are transcoded using locally stored or generated code books. Code books for transcoded documents received at a wireless mobile communication device are either retrieved from a memory on the device or requested from a data server. In response to a code book request, a data server retrieves a requested code book from a local memory or generates the requested code book and returns the requested code book to a requestor. A wireless mobile communication device may also generate and transcode XML documents using a locally stored code book, a locally generated code book, or a code book received in response to a code book request.

System and method for processing extensible markup language (XML) documents

Systems and methods for processing documents are disclosed. Documents received at a data server are transcoded using locally stored or generated code books. Code books for transcoded documents received at a wireless mobile communication device are either retrieved from a memory on the device or requested from a data server. In response to a code book request, a data server retrieves a requested code book from a local memory or generates the requested code book and returns the requested code book to a requester. A wireless mobile communication device may also generate and transcode XML documents using a locally stored code book, a locally generated code book, or a code book received in response to a code book request.

A system and method for reducing congestion in wireless communication systems is provided. An unsolicited message reduction system includes a message detector and an all points bulletin (APB) generator. The message detector applies predefined filtering rules to identify and act upon unsolicited email messages to reduce the total number of transmissions in the wireless communication system. The filtering rules include global and user rules, with the global rules normally having precedence over user rules. The APB generator allows messages to be sent wireless mobile communication devices through direct wireless messages instead of through email messages.
