A gateway turns encrypted PS data traffic on the Iub interface into clear IP packets so that WAN stream de-duplication and other optimization can be performed to eliminate the transfer of repetitive data across the Iub interface, thereby increasing the throughput between the NodeB and the RNC of the WCDMA network. The gateway pulls PS data traffic out from Iub without disturbing the signaling and CS traffic. The bifurcated PS data traffic is redirected to the GTP I/O port of the gateway where the stream de-duplication is applied. Deployment of the gateway is transparent to the WCDMA network. No network reconfiguration is required to deploy the gateway on the Iub interface.

Optimizing mobile network bandwidth

In one embodiment, a wireless system comprises a host MSC/VLR of a public land mobile network (PLMN) and a plurality of base station subsystems (BBSs). Each BSS includes a respective base station controller (BSC) and one or more base transceiver stations (BTSs). The wireless system further comprises a virtual base station controller (VBSC) communicatively coupled to the plurality of BSSs and the host MSC/VLR. The VBSC appears, from the perspective of the host MSCNLR, to be a base station controller for the BTSs in the plurality of BSSs. The VBSC and at least some of the BSSs include functionality for locally switching calls in the BSSs.

Some embodiments include a method for providing roaming service for a wireless device of a person that is both a prepaid subscriber of a local network and a subscriber of a home network with which the local network has a roaming agreement. Other embodiments of related systems and methods are also disclosed.

Open to all prepaid roaming systems and methods

In one embodiment, a private cellular system provides private cellular service and public cellular service using licensed frequency spectrum associated with a public land mobile network (PLMN). The system is configured to have a predetermined phone number that a subscriber who is using the public cellular service via the private cellular system and who is not registered to use the private cellular service provided by the system can call in order to register to use the private cellular service provided by the system and, in response thereto, the system captures a subscriber identity number associated with the subscriber and assigns a private telephone number to the subscriber that is used in connection with providing private cellular service. Another embodiment is directed to a method of enabling a prepaid hybrid subscriber to make a call using a private cellular system while outside of a coverage area associated with the private cellular system. Another embodiment is directed to a private cellular network comprising a plurality of private cellular systems to provide private cellular service and public cellular service using licensed frequency spectrum associated with a public land mobile network (PLMN). In that embodiment, a gateway function in each of the plurality of private cellular systems is configured to make the private cellular network appear, to the PLMN, as though it is implemented using only a single private cellular system.
