Abstract
Examples are disclosed that facilitate using enhanced cell global identifier to effectively manage the handover of cellular communication services for a mobile device in an LTE network from a source, or serving, evolved Node B (eNB) to a target home evolved Node B (HeNB). The increased use of HeNBs to provide service to mobile devices creates issues for the management of tracking area identifiers associated with the eNB and HeNBs and may increase tracking area update (TAU) signaling in the cellular network. The handover of a mobile device moving from an eNB coverage area to a neighboring HeNB coverage area is managed without use of a tracking area identifier by using enhanced cell global identifiers assigned to the respective HeNB. The following provides examples for minimizing the burden on the network devices to manage the administration of TAIs and that may reduce TAU signaling in the cellular network.
