BlackBerry Mobile Data System 6

Feature Description

• The BlackBerry Enterprise Solution also supports other security standards, including

Transfer Layer Security (TLS), Secure Socket Layer (SSL), Secure Multipurpose Internet

Mail Extensions (S/MIME), IT security policies, code signing, and certificates.

• System administrators can also set IT policies to enforce corporate security policies,

such as a minimum password length requirement (see the BlackBerry Enterprise Server

IT Policy Reference Guide for more information on IT policies). Additionally, if a

BlackBerry device is lost or stolen, system administrators can send IT commands

wirelessly to lock the BlackBerry device or to delete user and corporate data from it.

Data push The architecture that is used for BlackBerry wireless email is available for custom wireless

application data. For Browser and Java application models, server-side applications, written

in a variety of programming languages, retrieve content from a corporate web server, an

application server, or a database. The applications then send HTTP POST or Push Access

Protocol (PAP) requests to the connection service to send the content proactively to specific

BlackBerry device users. BlackBerry MDS Studio applications use web services eventing

(WS-Eventing) to provide similar functionality.

Flexibility Organizations can choose every component of a mobile wireless environment, including

BlackBerry devices, networks, applications, and vendors, and they can support a diverse

array of corporate data, applications, and legacy systems.

Wireless

interoperability

The BlackBerry MDS solution provides connectivity to multiple wireless networks globally

on a common architecture.

Management System administrators can use centralized tools to track and control BlackBerry devices, to

control network and server access, and to deploy applications to help maintain the integrity

of enterprise systems in a wireless environment.

Pushing content to users

Instead of waiting for users to access data, application developers and system administrators can proactively

send the data that users need. Server-side applications can send automatic updates and alerts when data

changes, without users requesting the new content. For example, corporations can enable sales people to

Push services can be used with any of the BlackBerry MDS application models. The BlackBerry Browser includes

a listener for push connections. Application developers can also design BlackBerry MDS Java or BlackBerry MDS

Studio applications that listen silently in the background for push requests.

Server push applications provide several advantages:

Advantage Description

Use the network

efficiently

Applications use the network efficiently because they send data only when it has changed.

BlackBerry device users do not have to retrieve information periodically, and applications do

not have to poll for updates.

Increase user

productivity

BlackBerry device users can be productive because they do not have to check for new

information. System administrators can configure applications to send updated content or

alerts immediately and to notify users when content arrives.

Increase

information

availability and

timeliness

BlackBerry device users can access the most current information. This information can be

cached on the BlackBerry device, so users can retrieve it even when they are outside a

wireless coverage area.

All push application content is compressed and encrypted over the network in the same way as all other

BlackBerry communication, and content can also be encrypted on the BlackBerry device if content protection is

enabled. The BlackBerry Infrastructure manages the connection to the wireless network and verifies that content

is delivered to users as soon as they are in a wireless coverage area.

For examples of browser push services, see “Pushing content to the BlackBerry Browser” on page 10.
