Push service messages are an ideal way for service providers to activate users, because they can be used to notify users of updated content or to alert them about information in their areas of interest. Service messages indicate downloadable content. The user can view indicated content by using the Service Inbox and the browser.

The Service Indication content type enables an alert message to be sent to users. A Service Indication must contain at least the text to be displayed to the user and a URL address of content that may be dynamically generated for each push message in the application server. In addition to text and a URL address, the service indication can optionally contain the following information:

• Creation Date and Time
• Expiration Date and Time
• Service Indication ID
• Priority.

Each Service Indication has a Service Indication ID, which is used to uniquely identify different kinds of Service Indications. Service providers set the Service Indication IDs for messages. The ID allows reception of multiple Service Indications with the same URL address and priority level. If the received Service Indication has the same ID as the one stored in memory, the received Service Indication will replace the stored one only if it is newer. Priority levels define how the received messages are ordered in the Service Inbox and also whether the user is notified about the received

Service Loading (SL) content type enables a URL address to be sent to a device, which then "pulls" the content at that URL from the origin server without the user specifically requesting it. Because the user may be busy doing other things when the service loading content is received, the intrusiveness level can be set. Service Loading messages are useful, for example, for operators, who can use an SL push message to update the Operator menu content in the device. Service Loading is not supported in all devices, and should be checked from the Browser Characteristics in Nokia GSM Devices document. A Service Loading content type has one mandatory href attribute and one optional action attribute. The href attribute is the URL of the service application to be loaded and the action attribute specifies the action that should be taken after "pulling" the service application.
