A server device in a long term evolution (LTE) network may store, in a memory, context information, associated with a prior communication session between the LTE network and a user device, where the context information permits a communication session to be established within a time period, the time period being less than another time period to initially establish the communication session or to establish the communication session without the context information. The server device may further receive a registration request associated with the user device; determine whether the memory stores the context information; perform, within the time period, an abbreviated registration operation to establish the communication session with the user device, using the context information from the memory, when the memory stores the content information; and perform, within the other time period, a registration operation to establish the communication session when the memory does not store the context information.
