Devices, computer-readable media, and methods are disclosed for establishing a secure tunnel having a path that includes an untrusted link between a wireless access point and a gateway device. For example, a processor may detect a security event associated with a wireless access point that is in communication with a gateway device of the telecommunication network via a trusted link, establish a secure tunnel between the gateway device and an endpoint device that is accessing the telecommunication network via the wireless access point and the gateway device, and transport payload traffic between the endpoint device and the gateway device via the secure tunnel. A path of the secure tunnel may include an untrusted link between the wireless access point and the gateway device. In addition, the payload traffic that is transported via the secure tunnel may be indecipherable by the wireless access point.

Trust mode switching for wireless access points

Enabling a changing of a state of a device based on a hierarchical class of the device is disclosed. Non-macro radio access network (RAN) devices can be comprised in a network connected to a macro RAN device via a gateway RAN device. The gateway RAN device can be connected to a field RAN device via an intermediate RAN device. A state of a field RAN device can be altered based on a criterion. In an embodiment the criterion can be use of the hierarchical class of the RAN device, e.g., a field class RAN device, by an active or idle UE. In an embodiment the criterion can be use, by an active or idle UE, of another RAN device that is a logical neighbor to the field RAN device. Altering the state can result in a power savings or improved interference characteristics of the network.

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.

Auto-discovery of a non-advertised public network address

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.

Transporting call data via a packet data network

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.

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.

Using standard cellular handsets with a general access network

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.

General access network controller bypass to facilitate use of standard cellular handsets with a general access network

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.

Jitter management for packet data network backhaul of call data

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.

Access control in a cellular system

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.
