Carriers and carrier configuration

A carrier is a MobiLink object that is stored in MobiLink system tables or a Notifier properties file, that contains information about a public carrier for use by server-initiated synchronization.

You must configure a wireless carrier to send push notifications through an SMTP gateway because the Notifier needs to construct valid email addresses. You must also configure a wireless carrier when using a device tracking gateway with a subordinate SMTP gateway enabled.

Carrier properties, such as the network provider ID and the SMS email prefix, are configured on a MobiLink server. To accommodate multiple carrier services, configure multiple carriers on the MobiLink server.

Sender syntax

When a push notification is received by a MobiLink Listener and preprocessed for message filtering, it is divided into several keywords. The sender keyword in a message is an email address, which is generated by the device and varies depending on the wireless carrier. For more information about preprocessing messages, see Message syntax.

The sender syntax is in the following format:

sender = sms_email_user_prefix phone-number@sms_email_domain

Note

There are no spaces between sms_email_user_prefix and phone-number.

The sms_email_user_prefix and sms_email_domain values are carrier properties that should be configured on the MobiLink server. The phone-number value is taken from the address column of the ml_device_address system table.

To determine the sender syntax, run the MobiLink Listener on a device that uses a carrier service. Enable message logging, and set verbosity to level 2 using the dblsn -m and -v options. Check the message log after loading the MobiLink Listener.
