Establishing sessions between devices in a network

摘要

A method may include generating a discovery ID, wherein the discovery ID identifies an IP connection between a network device and a user device. The method may further include receiving a short message service(SMS) message from the user device, wherein the SMS message includes the discovery ID. The method may further include determining a telephone number associated with the user device based on a sender ID of the SMS message. Further, the method may also include transmitting a value indicative of the telephone number to the user device through the IP connection based on the discovery ID received in the SMS message.
