Abstract
A data communication system pre-registers User Equipment (UE) to a Long Term Evolution (LTE) tracking area in an LTE network before the UE attaches to the LTE network. A voice communication network receives a release message for a user voice session and responsively transfers a pre-attachment message to an MME in the LTE network comprising a UE Identifier (ID), a serving base station ID, and an indication that the UE will attach to the LTE network. The MME processes the base station ID to select an LTE network Physical Cell Identity (PCI), processes the LTE network PCI to select an LTE tracking area, and pre-registers the UE ID to the selected LTE tracking area. An LTE base station receives an attachment request from the UE based on the LTE network PCI and responsively attaches the UE to the LTE network without performing a tracking area update.
