`ABSTRACT
`( 57 )
`Embodiments herein provide , for example , a method that
`includes , comprising : sending a request , by a first user on a
`first device , to a server , the request comprising requesting
`the server open an ephemeral communication session with a
`second user on a second device ; allocating resources , by the
`server , to begin the ephemeral communication session
`between the first user and the second user ; generating a
`unique ephemeral communication session identifier by the
`server and transmitting the unique ephemeral communica
`tion session identifier to the first user ; transmitting , by the
`first user , the unique ephemeral communication session
`identifier to the second user using a second communication
`channel ; connecting , by the second user , to the first user
`through the ephemeral communication session using the
`unique ephemeral communication session identifier ; and
`connecting , by the first user , to the second user through the
`ephemeral communication session using the unique ephem
`eral communication session identifier . In such a method ,
`connecting , by the second user , to the first user through the
`ephemeral communication session may include connecting
`to the server ; and connecting , by the first user , to the second
`user through the ephemeral communication session may
`include connecting to the server .
