Long term evolution (LTE) communication system to transfer communications from non-LTE to LTE networks
First Claim
1. A method of operating a Long Term Evolution (LTE) communication network wherein an LTE gateway system exchanges LTE registration data and Internet Protocol (IP) Multimedia Subsystem (IMS) registration data with User Equipment (UE) over a non-LTE communication network, the method comprising:
- the LTE gateway system transferring networking data for the UE to an LTE control system responsive to an IMS media session for the UE and transferring an instruction to remove the networking data for the UE from the LTE control system responsive to termination of the IMS media session, wherein the networking data characterizes the IMS media session over the non-LTE communication network through the LTE gateway system;
the LTE control system receiving an LTE initial access message for the UE and if the networking data characterizes the IMS media session over the non-LTE communication network through LTE gateway system, then transferring a session transfer message to the LTE gateway system to switch communication access for the UE from the non-LTE communication network to the LTE communication network and responsively detach from the non-LTE network; and
the LTE control system receiving an LTE session termination message for the UE and responsively transferring an LTE reattach message to the LTE gateway system to force the UE to reattach to the LTE communication network.

Abstract
In a Long Term Evolution (LTE) network, an LTE gateway system exchanges registration data with User Equipment (UE) over a non-LTE network. The LTE gateway system transfers networking data to an LTE control system responsive to an IMS media session for the UE, and transfers an instruction to remove the networking data from the LTE control system responsive to termination of the IMS media session. The LTE control system receives an LTE initial access message and if the networking data characterizes the IMS media session over the non-LTE network through the LTE gateway system, then transfers a session transfer message to the LTE gateway system to switch communication access from the non-LTE network to the LTE network. The LTE control system receives an LTE session termination message and responsively transfers an LTE reattach message to the LTE gateway system to force the UE to reattach to the LTE network.
