METHOD TO ESTABLISH A MESSAGE EXCHANGE BETWEEN MOBILE DEVICES OVER A DATA CONNECTION

摘要

A technique for notifying an effectively offline messaging target that a messaging participant wishes to establish a messaging session with the messaging target involves sending a messaging wakeup message on an offline communication channel. Responsive to the messaging wakeup message, the messaging target can open an applicable data channel with a wireless operator. The sender of the messaging wakeup message and the recipient thereof can then engage in a messaging over a data connection session with one another.
