This section provides details about the mobility feature and how to plan for deploying it. · In This Section · Mobility Features and Capabilities · Topologies and Components for Mobility · Technical Requirements for Mobility · Defining Your Mobility Requirements · Deployment Process for Mobility · Mobility Features and Capabilities The mobility feature in Lync Server 2010 supports Lync functionality on mobile devices. When you deploy the Microsoft Lync Server 2010 Mobility Service, users can use supported Apple iOS, Android, Windows Phone, or Nokia mobile devices to perform such activities as sending and receiving instant messages, viewing contacts, and viewing presence. In addition, mobile devices support some Enterprise Voice features, such as click to join a conference, Call via Work, single number reach, voice mail, and missed calls.

Note: Not all features work exactly the same on all mobile devices. For details about features supported on mobile devices, see Mobile Client Comparison Tables. For details about supported devices and operating systems, see the requirements topics under Planning for Mobile Clients. When you use the Microsoft Lync Server 2010 Autodiscover Service along with the Mobility Service, mobile applications can automatically locate Lync Server Web Services without requiring users to manually enter the URLs in their device settings. Manually entering URLs in mobile device settings is also supported, primarily for troubleshooting purposes. The mobility feature also supports push notifications for mobile devices that do not support applications running in the background. A push notification is a notification that is sent to a mobile device about an event that occurs while a mobile application is inactive. Examples of events that can result in a push notification are missed instant messaging (IM) invitations or missed calls. The Mobility Service, Autodiscover Service, and support for push notifications are provided in the cumulative update for Lync Server 2010: November 2011. · Topologies and Components for Mobility To support Lync mobile applications on mobile devices, the cumulative update for Lync Server 2010: November 2011 provides three new services. This section briefly describes these components and identifies the Lync Server 2010 topologies that support mobility. · Mobility Components The new services that support mobility are as follows: · Microsoft Lync Server 2010 Mobility Service This new service supports Lync 2010 functionality, such as instant messaging (IM), presence, and contacts, on mobile devices.

Note: For a complete list of supported Lync features on mobile devices, see Mobile Client Comparison Tables. The Mobility Service is installed on every Front End Server in each pool that is to support Lync functionality on mobile devices. When you install the Mobility Service, a new virtual directory (Mcx) is created under both the internal website and the external website on your Front End Servers. · Microsoft Lync Server 2010 Autodiscover Service This new service identifies the location of the user and enables mobile devices to locate resources, such as the internal and external URLs for Lync Server Web Services and the URL for the new Mobility Service, regardless of network location. Automatic discovery uses hardcoded host names (lyncdiscoverinternal for users inside the network and lyncdiscover for users outside the network) and the SIP domain of the user. It supports client connections using either HTTP or HTTPS. The Autodiscover Service is installed on every Front End Server and on every Director in each pool that is to support Lync functionality on mobile devices. When you install the Autodiscover Service, a new virtual directory (Autodiscover) is created under both the internal website and the external website on both Front End Servers and Directors. · Microsoft Lync Server 2010 Push Notification Service This service is a cloud-based service that is located in the Lync Online datacenter. When the Lync mobile application on a supported Apple iOS device or Windows Phone is inactive, it cannot respond to new events, such as a new instant messaging (IM) invitation, a missed instant message, a missed call, or voice mail, because these devices do not support mobile applications running in the background. In such a case, a notification, called a push notification, for the new event is sent to the mobile device. The Mobility Service sends the notification to the cloud-based Push Notification Service, which then sends the notification either to the Apple Push Notification Service (APNS) (for supported Apple iOS devices) or to the Microsoft Push Notification Service (MPNS) (for Windows Phone), which sends it on to the mobile device. The user can then touch the notification on the mobile device to activate the application.
