CoBrA: Context Broker Architecture -- CTMC@eBiquity User Guide

CTMC@Ebiquity User Guide

The following instructions only applies to cellphone users who have T-Mobile as their service provide.

Step 1. Decide what command to send to the Broker

Step 2. Send an email message over SMS

Because the Context Broker does not have a designated SMS alias name in the T-Mobile network, we use the Email-over-SMS service (500).

Compose a new text message and enter "500" at the TO field.

In the beginning of the message body, enter "cobra@cs.umbc.edu". This is email address of the Context Broker that the SMS message will be routed to.

Enter a blank space after the email address.

Enter the CTMC command followed by the '#' character.

To: 500

cobra@cs.umbc.edu qMeeting#

Fig. 1: an example CTMC message. By sending this message over the T-Mobile network, you ask the Broker to answer a list of today's meeting event (incld. title, and meeting ID).

Send the message.

Few minutes later, you should receive a reply message from the Context Broker.
