Abstract: Enabling a standard cellular handset to be used to access a core mobile network via a generic access network is disclosed. A communication between a generic access network element and the core mobile network is intercepted. A modified version of the communication is generated. The modified communication is forwarded.

Abstract: Providing mobile network security is disclosed. A first mobile network provider equipment registers using a secret data that is known to a registration entity with which the first mobile network provider equipment is configured to register and embodied in a physical device associated with the first mobile network provider equipment in a manner that enables the physical device to be used to perform a cryptographic function using the secret data but prevents the physical device from being used to provide the secret data as output. An encryption data usable to communicate securely with a second mobile network provider equipment over a packet data network is received from the registration entity.

Abstract: Facilitating use of a restricted base transceiver station is disclosed. To a first set of subscribers associated with a mobile network operator, access to a mobile network is provided via base transceiver stations associated with a first mobile network identifier associated with the mobile network operator but not via base transceiver stations associated with a second mobile network identifier associated with the mobile network operator. To each of a second set of subscribers associated with the mobile network operator, access to the mobile network is provided via a corresponding subset of a set of base transceiver stations associated with the second mobile network identifier, the subset including for each subscriber in the second set one or more base transceiver stations with respect to which that subscriber is an authorized user.

Abstract: Managing packet data network jitter is disclosed. A first call data associated with a mobile network communication session is received. A second call data that is older than the first call data is dropped from a buffer if required to make room in the buffer for the first call data.

Abstract: Using a single logical base transceiver to serve multiple physical locations is disclosed. A call traffic associated with a call associated at a mobile network with an assigned timeslot of a logical base transceiver is received. A timeslot with which the call traffic is associated is remapped from the assigned timeslot to a serving timeslot being used at a serving physical base transceiver to facilitate the call, in the event the call traffic comprises inbound call traffic being sent into the mobile network from the serving physical base transceiver, or from the serving timeslot to the assigned timeslot in the event the call traffic comprises outbound call traffic being sent from the mobile network to the serving physical base transceiver.

Abstract: Controlling use of a mobile network element is disclosed. An indication is received that a mobile station associated with a mobile network is attempting to access the mobile network via a base transceiver station that (1) the mobile station is not authorized to use and (2) is located within a geographic area from which the mobile station is authorized to access the mobile network. The mobile station is prevented from accessing the mobile network via the base transceiver station.

Abstract: Establishing a secure connection on behalf of a mobile station is disclosed. An identifier associated with a mobile station is obtained. The identifier and a secret data not associated with the mobile station are used to establish on behalf of the mobile station a secure connection to a generic access network element configured to provide connectivity to a core mobile network.

Abstract: Mobile communication is disclosed. A standard cellular mobile station at is communicated with at least in part via a standard cellular air link. A mobile communication between the standard cellular mobile station and a core mobile network is relayed via a generic access network. In some embodiments, translation between the standard cellular air link and a generic access network uplink interface is performed.

A communication between a generic access network element and the core mobile network is intercepted. A modified version of the communication is generated. The modified communication is forwarded.

Abstract: Managing packet data network jitter is disclosed. A first call data associated with a mobile network communication session is received. A second call data that is older than the first call data is dropped from a buffer if required to make room in the buffer for the first call data.

Abstract: Providing a network address is disclosed. A communication indicating that a first node desires to communicate via a packet data network with a second node configured to provide access to a private resource is received. A non-publicly advertised packet data network address usable to communicate with the second node via the packet data network is provided to the first node.

An encryption data usable to communicate securely with a second mobile network provider equipment over a packet data network is received from the registration entity.

Abstract: Transporting call data is disclosed. A first call data associated with a first communication session and a second call data associated with a second communication session are received. The first call data and the second call data are bundled into a single data packet for transport over a packet data network.
