The Session Initiation Protocol to Internet Operating System adapter conveys the depacketized message content to the base transceiver station which transmits the message content to the user equipment via a data burst.

Abstract: A system, method, and computer readable medium for configuration of a femtocell system is provided. A femtocell system is provisioned with a default base station manager IP address. The base station manager receives an account identifier of a user subscription and a femtocell system ID assigned to the femtocell system. The base station manager may allocate a SID/NID for the femtocell system. A list of electronic serial numbers of handsets in the user subscription may be compiled by the base station manager. The femtocell system may connect with the base station manager and request a configuration download once deployed in a SOHO. The compiled electronic serial numbers may then be transferred from the base station manager to the femtocell system in a configuration download.

Abstract: A system, method, and computer readable medium for handoff of a user equipment from a macrocellular system to a femtocell system is provided. A micro-pilot assisted handoff routine may be implemented to facilitate handoff of a user equipment from a macrocellular system to a femtocell system. The femtocell system may transmit very low power pilot, paging, and synch channels on a common frequency used by the macrocellular system. In another embodiment, a mobile assisted handoff routine facilitates handoff of a user equipment from a macrocellular system to a femtocell system. The user equipment's preferred roaming list includes an entry for the femtocell system and specifies a SID/NID and pseudo-noise offset for the femtocell system. The user equipment is configured to periodically enter a search mode to attempt to locate the femtocell system by switching to a femto carrier that is specified in the preferred roaming list.

Abstract: A system, method, and computer readable medium for processing registration and authentication procedures by an IP-based femtocell system are provided. The femtocell system includes a base transceiver station and a Session Initiation Protocol to Internet Operating System adapter. The femtocell system receives a registration message from a user equipment, issues a location update request on behalf of the user equipment, transmits a register message to a core network, receives an authentication request from the core network, and transmits an authentication challenge to the user equipment.

Abstract: A system, method, and computer readable medium for terminating calls in a network system is provided. The communication system features an IP-based femtocell system for provisioning communication services to a user equipment. The femtocell system is provisioned with a list of electronic serial numbers of user equipments that are authorized to access the femtocell system. When a call is received by the femtocell system, the femtocell system determines a directory number of a user equipment to which the call is directed. If the destination user equipment is authorized to access the femtocell system and is currently within the service area of the femtocell system, the call setup may be completed by the femtocell system without any call setup signaling being transmitted to a core telecommunication network.

Abstract: A system, method, and computer readable medium for processing a call setup in a network system are provided. A femtocell system receives a call origination for a call to be terminated with a user equipment serviced by the femtocell system from a core network, transmits a page message to the user equipment, performs a service connection with the user equipment, creates a connection for the core network, and completes the call setup with the user equipment.

Abstract: A system, method, and computer readable medium for transmit protection in a femtocell system are provided. A multi-stage transmit protection routine prohibits radio transmissions for unregistered femtocell systems and transmissions from femtocell systems in unauthorized areas. A femtocell system may request transmission authorization from a base station manager. The base station manager may provide an authorization failure if the femtocell system is not registered or if the source address of the femtocell system is not within a predefined distance of a registered location of the femtocell system. If the femtocell is provided a transmission authorization, the femtocell system may obtain a GPS location from a user equipment and provide the GPS location to the base station manager which evaluates the location. The base station manager may provide an authorization failure if the GPS location is not within a predefined distance of the registered location of the femtocell system.

Abstract: A system, method, and computer readable medium for abbreviated dialing in a femtocell network is provided. A user having authorized access to the femtocell network may dial another authorized user using an abbreviated code. On receipt of the call request, a femtocell system may evaluate the destination number to determine if it is an abbreviated code. If the dialed number is not an abbreviated code, the femtocell system may direct the call request to the telecommunication core network for processing thereby. If the dialed number is evaluated by the femtocell system as an abbreviated code, the femtocell system may direct the call request to an on-site PBX for call handling. If the abbreviated code is a valid code and the dialed user equipment is currently in the femtocell network service area, the PBX may then complete the call setup within the femtocell network.

Abstract: A system, method, and computer readable medium for provisioning communication services by an IP-based femtocell network is provided. Service of a user equipment may be transferred from one femtocell to another femtocell via a femtocell handoff procedure. Femtocell systems of the femtocell network perform link quality measurements and may distribute the link quality measurements to neighbor femtocells. A femtocell system may periodically evaluate the link quality with the user equipment. If an evaluation is made that the user equipment needs to be transferred to another site, the servicing femtocell site may evaluate the most recent link quality measurements received from neighboring femtocell sites and select a femtocell site for handoff. In the event that the femtocell network is deployed in an area serviced by a macrocellular network, handoff routines may provide preference for transferring the user equipment to a target femtocell system rather than a macrocell site.

Abstract: A system, method, and computer readable medium for provisioning radio access via a femtocell system that includes integrated BTS and BSC functions are provided. The femtocell system is coupled with a packet switched backhaul and provides an IP-accessible radio access network. The femtocell system includes a session initiation protocol adapter that supports a SIP client pool and provides conversion of call set-up functions to SIP client set-up functions for provisioning of radio access to a user equipment. The user equipment may have a session initiation protocol client associated with the user equipment. The session initiation protocol client is hosted and registered with a registrar service by the femtocell system. Accordingly, telecommunication services may be directed to and from the user equipment over the packet-switched backhaul to the user equipment via the femtocell system.
