Abstract: Systems and methods for small cell idle mode mobility include receiving, at a first small cell of a preconfigured cluster of small cells, a mobility area update request from a user equipment (UE). The method can also include registering location information of the UE with a small cell gateway, and retrieving a core network periodic timer for the UE from a mobility server. If certain conditions are met, the first small cell forwards the mobility area update request to a core network via the small cell gateway. Otherwise, the method can include the first small cell updating the location information of the UE with the mobility server, generating a locally-generated mobility area update accept message, and sending a locally generated mobility area update accept message to the UE along with a local periodic timer instructing the UE to send another mobility area update request when the local periodic timer expires.

Abstract: An example method is provided in one example embodiment and may include assigning an identifier to each of a plurality of Home Node Bs (HNBs); receiving a cell update for a user equipment (UE) transitioning from a first HNB to a second HNB, wherein the cell update for the UE includes a first identifier associated with the first HNB and wherein the UE is in a cell paging channel (PCH) mode; determining based, at least in part, on the first identifier associated with the first HNB, whether the first HNB is operating within a cluster of HNBs including the second HNB; and withholding registration of the cell update for the UE with an HNB gateway (HNB-GW) if the first HNB is operating within the cluster of HNBs including the second HNB until packet switched (PS) traffic for the UE is received by the second HNB.

Abstract: An example method is provided in one example embodiment and includes receiving a handover request from a first radio network to handover a user equipment (UE) to a second radio network, wherein the handover request includes an international mobile subscriber identity (IMSI) for a user associated with the UE and a pseudo cell identifier (ID); determining a target channel configuration for the UE using the pseudo cell ID; querying a third radio network using the user IMSI to determine a location of the UE, wherein at least one access point in the third radio network is in communication with the UE; and selecting a particular target access point in the second radio network for handover of the UE based, at least in part, on the location of the UE, the target channel configuration for the UE and a location of the particular target access point.

Abstract: A serving gateway updates location information for a mobile device based on information in an update bearer request. The serving gateway receives a first update bearer request for a mobile device. The first update bearer request includes a first address associated with a micro cellular service base station to which the mobile device is in communication. The micro cellular service base station is associated with a physical location. The serving gateway sends a location notification to a location server, indicating that the mobile device is physically near the micro cellular service base station. The serving gateway receives a second update bearer request for the mobile device including an address associated with a macro cellular service base station. The serving gateway sends another location notification to the location server indicating that the mobile device is no longer at the physical location of the micro cellular service base station.
