Techniques for database connection management and governance in a multi-tenant provider network are described. One or more database proxy instances connect to client applications and can obtain database connections for these client applications. The database connections may be pinned to particular client applications and/or multiplexed and thus shared by multiple client connections.

Multi-tenant provider network database connection management and governance

An example method is provided in one example embodiment and includes receiving an assignment request from a core node in a network to establish a tunnel for user plane traffic; forwarding first parameters to a controller of an enterprise network, wherein the first parameters include a tunnel identifier and a network address associated with the core node; receiving an assignment response; and forwarding second parameters to the core node, wherein the second parameters include a tunnel identifier and a network address associated with the controller. In some instances, the assignment request can be a request to establish a tunnel for user plane data traffic. In some instances, the assignment request can be a request to establish a tunnel for user plane voice traffic.

System, method and apparatus for small cell gateway selective data path offload

An example method is provided in one example embodiment and may include determining a presence of user equipment (UE) in relation to small cell radio(s) of a small cell network based on information obtained through the small cell network and one or more parallel networks; and adjusting transmit power for the small cell radio(s) based on the presence of UE in relation to the small cell radio(s). Another example method can include determining that a UE in cell paging channel mode has changed its selected macro cell radio; determining that the UE is allowed service on a small cell radio located in a vicinity of a macro cell coverage area of a selected macro cell radio; and adjusting a transmit power of the small cell radio based on a presence of the UE in a surrounding macro cell coverage area of the small cell radio.

System and method for managing interference in a network environment based on user presence

Techniques are provided to perform location verification of a radio access point device such as femtocell. The radio access point device is configured to receive signals from global positioning system (GPS) satellite transmitters to produce GPS location data representing a GPS location of the radio access point device. The radio access point device is also configured to receive wireless signals at one or more specified channels and to generate radio environment data representing characteristics of received wireless signals. A comparison is made between the GPS location data and reference GPS location data for an expected location of the radio access point device. When the GPS location data substantially matches the reference GPS location data, operations of the radio access point device are enabled and the radio environment data is stored to be used as reference radio environment data for purposes of subsequent location verification of the radio access point device.

Radio access point location verification using GPS location and radio environment data

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.

Systems, methods and media for small cell idle mode mobility

An example method is provided in one example embodiment and includes receiving a request to relocate a user equipment (UE) from a source macro radio to an ambiguous small cell access point (AP), wherein the request includes a target cell identity (ID) encoded with a source macro cell identifier for the source macro radio and a target sub-carrier identifier for the ambiguous small cell AP; determining potential target small cell APs for relocation of the first UE using the using the first target cell ID, wherein each of the potential target small cell APs are within a coverage area of the source macro radio and operate using the target sub-carrier identifier; and preparing, for each of the potential target small cell APs, a common channel to receive relocation of the first UE. The first UE can relocate to a particular target small cell access point using the common channel.

System and method for providing handover to an ambiguous small cell access point in a network environment

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.

Serving gateway-based presence/location detection

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.

System and method for supporting cell updates within a small cell cluster for idle mobility in cell paging channel mode

Systems and methods for controlling the power of small cells in a coverage area includes obtaining signal strength measurements of wireless signals received from a plurality of small cells in a defined coverage area by identifying signal strength at a plurality of locations near the perimeter of the coverage area, and determining a revised transmit power of the small cells based on the determined signal strength (a) to maintain a minimum threshold of received signal while reducing the average power within the coverage area, or (b) to reduce leakage outside the perimeter of the coverage area relative to a desired threshold.

Walk-assisted automated AP coverage adjustment

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.

System and method for hand-in disambiguation using user equipment WiFi location in a network environment

An example method is provided in one example embodiment and includes receiving, by a first Home eNodeB (HeNB), a first attach request from a user equipment (UE) for attaching a subscriber associated with the UE to a small cell network; determining whether the subscriber has transitioned into the small cell network from a macro cell network; exchanging, based on the determination, a first pair of messages between the first HeNB and the UE to determine an International Mobile Subscriber Identity (IMSI) of the subscriber; and exchanging, based on the determination, one or more second pairs of messages between the first HeNB and the UE to advance a sequence number for Non-Access Stratum (NAS) messages for the UE to a value corresponding to a received sequence number for the first attach request from the UE.
