An arrangement for dynamic account allocation is achieved by pooling together spectrum and network availability, as well as congestion information, from different service providers in a central database and by the purchase of wholesale volume of network capacity or accounts with predetermined monthly usage. The purchased network capacity is dynamically allocated to devices of different origin and ownership. The central system operator administrates the rebilling and reconciliation of any fractional usage to each device. Unlike other proposed solutions that require the carriers to bet on proprietary technologies and involve changes to the network and high capital expenditures to build and operate the network, the present invention requires no changes to the carrier's network and no investment in a proprietary solution.

The invention discloses a wireless communication handset comprising licensed wireless communication signal processing circuitry and unlicensed wireless communication signal processing circuitry. The invention further discloses a control circuit connected to both the licensed wireless communication signal processing circuitry and the unlicensed wireless communication signal processing circuitry, and a computer readable memory for directing the control circuit to function in a specified manner. This memory includes instructions to formulate a measurement report containing signal strength information that corresponds to the strength of a signal received through the unlicensed wireless communication signal processing circuitry. The measurement report also contains a request to transfer a wireless communication session from a licensed wireless system to an unlicensed wireless system. The memory further includes instructions to transmit the measurement report to the licensed wireless system through the licensed wireless communication signal processing circuitry.

Apparatus for Supporting the Handover of a Telecommunication Session between a Licensed Wireless System and an Unlicensed Wireless System

Some embodiments provide a method of identifying a list of Femtocell Access Points (FAPs) for a user equipment (UE) communication session in a communication system including a first wireless communication system and a second wireless communication system. The second wireless communication system includes multiple FAPs and a Femtocell gateway (FGW) that communicatively couples the FAPs to the first wireless communication system. The method receives information about a UE that has detected a particular FAP that has an identification attribute. The method uses the UE information to retrieve a set of FAPs designated for the UE where the FAPs in the set of FAPs have the same identification attribute as the particular FAP. The retrieved set of FAPs is from a set of several FAPs that are not designated for the UE but have a same identification attribute as the particular FAP.

A fraudulent intruder can eavesdrop on a call by removing information about an encryption algorithm when a multimode mobile station sends an unpro-tected initial signaling message containing this information over the radio interface to the mobile telecommunications system. The attempt can be pre-vented in a universal mobile telecommunications system (UMTS) comprising at least two radio access networks providing mobile stations with access to at least one core network, a multimode mobile station, and at least one core network. During connection setup with a first radio access network, the mul-timode mobile station sends an unprotected initial signaling message that includes information about those encryption algorithms that the multimode mobile station supports when it communicates in a second radio access network. The first radio access network saves some or all the information of it. Then it composes and sends an integrity-protected message that includes information about the encryption algorithms supported by the multimode mobile station in the second radio access network.

A portable wireless network gateway aggregates bandwidth demand of different devices operating under different communications protocols Network connectivity is provided by encapsulating data from the different devices to make the data appear to be data native to a single network For example, the single network is a cellular wireless network The different communications protocols include but are not limited to IEEE 80211, IEEE 8023, USB, cellular wireless protocols, Bluetooth, RS-232, and IEEE 111R

Portable wireless gateway

A method and a wireless telecommunication system of performing network-assisted handover of calls between a serving network and another wireless network that employs communication protocols different from those of the serving network. A message is sent from a mobile station of a user to the serving wireless network, which includes an indication that the mobile station is capable of communicating with the neighboring wireless network. Information relating to the communication characteristics of the neighboring wireless network is also sent from the serving wireless network to the mobile station. Using the information relating to the communication characteristics of the neighboring wireless network, the mobile station receives radio signals from the neighboring wireless network. The quality of the radio signals between the mobile station and the neighboring wireless network is measured. The serving wireless network sends a message to the neighboring wireless network to request a handover of the communication transaction when the quality of the radio signals between the neighboring wireless network and the mobile station meets a predetermined minimum threshold. Then a handover of the communication transaction from the serving wireless network to the neighboring wireless network is executed after the neighboring wireless network has established a communication channel for the mobile station pursuant to the handover request.
