To permit seamless roaming, the network access arbitrator routes the data to the first wireless communication network via a first wireless interface and then seamlessly reroutes the data to a second wireless communication network via a second wireless interface. According to one embodiment, the network access arbitrator reroutes the data in response to the data bandwidths of the connections with the first and second wireless communication networks.

When an ad hoc network is formed between short range wireless devices, at least one device assumes the role of an ad hoc network information provider for the new piconet. In this role, the device allocates a browsing hierarchy of service classes in its service registry. The service classes will provide a record to characterize the ad hoc network. When a new wireless device arrives within the communication range of any member of the ad hoc network, its inquiry signals are answered by the first member detecting the inquiry. If that first member is an ad hoc network information provider, it responds with information accessed from its service registry characterizing the ad hoc network. If, instead, an ordinary device in the ad hoc network is the first to respond to the inquiry signals of the arriving device, the device responds with the address of the ad hoc network information provider. The arriving device then pages the ad hoc network information provider to obtain information characterizing the ad hoc network.

Devices, systems, and methods are disclosed to offload the usage of a cellular network by intelligent selection of broadband network connections such as Wi-Fi access points. A Wi-Fi transceiver on a mobile device is activated when certain conditions are met, such as a time, location, recognition of a radiofrequency (RF) environment, etc. The conditions are correlated with a database of known locations in which a one or more Wi-Fi access points are determined to exist. The Wi-Fi transceiver on the mobile device is activated and commanded to connect to a particular Wi-Fi access point. Dynamic intelligence ensures that the appropriate connection method is used, and minimizes handovers to networks or access points that are unreliable or that are predicted to become inaccessible to the mobile device.

A method and system for selecting a network to establish a connection to from a set of available network includes a network database providing historical information about each of the networks and sends the database information to end user terminals. The end user terminals monitor real-time performance information about each of the available networks and can send this information to the network database. The end user terminals also include network connection policy information which can be used to make the selection decision. The end user terminal determines a network quality score for each available network as a function of the historical information from the network database, the real-time performance information about each available network and the network connection policy information. The end user terminal can select the available network as a function of the network quality score, for example, selecting the available network with the highest network quality score.

In a radio access network (24) a femto radio base station (28_f) comprises a resident receiver (54) which acquires system information broadcast in a radio access network (24). At least part of the system information is used for building, at the femto radio base station (28_f), a neighbor data structure (59) comprising information for neighboring cells. The neighbor data structure (59) is then used for building a neighbor list. The neighbor list is subsequently transmitted from the femto radio base station (28_f) to a user equipment unit (30) served by the femto radio base station (28_f). In some example embodiments and modes, the femto radio base station (28_f) reports the neighbor data structure to a network node (26, 100) other than the femto radio base station. The other node (26, 100) uses the neighbor data structure for building the neighbor list at the other node. In some example embodiments and modes, acquisition of the system information comprises scanning a surrounding macro coverage area of the femto radio base station for obtaining cell identity information for detected cells. In other example embodiments and modes, the acquisition of the system information can additionally comprise camping on a macro cell and using/consulting at least one system information block in the camped-on macro cell is consulted/used for obtaining information about at least one neighboring cell.

Disclosed herein is a method and system for detecting, monitoring and/or controlling one or more of mobile services for a mobile communication device (also referred to herein as a Controllable Mobile Device or CMD), and in particular, when the device is being used and the vehicle, operated by the user of the device, is moving. The present method and system determines whether the vehicle is being operated by a user that may also have access to a mobile communication device which, if used concurrently while the vehicle is in operation, may lead to unsafe operation of the vehicle. If the mobile services control system determines that a vehicle operator has potentially unsafe access to a mobile communication device, the mobile services control system may restrict operator access to one or more services that would otherwise be available to the operator via the mobile communication device.

A method and system for coordinated dynamic access to radio spectrum for wireless networking includes defining a coordinated access band (CAB) from which radio access network (RAN) managers may request spectrum allocations in the form of time bound spectrum leases for their respective requesting base stations. In one embodiment of the present invention, a DIMSUMnet architecture is implemented to make some fundamental choices and to centralize the collection of information, such as spectral occupancy, thermal and adjacent frequency interference. Such collected information is subsequently used by a spectrum broker in making spectrum allocation decisions. The DIMSUMnet architecture of the present invention also introduces a RAN manager element to centralize the task of acquiring time bound spectrum leases and for configuring the base stations.

A system and method for providing network access are disclosed. After connecting to a network at an access point, a user of a computing device registers for network access with a network provider. In response to the registration, the network provider sends a completion page to the computing device. The completion page includes a link to an embedded file such as a small, transparent GIF image. When the computing device retrieves the embedded file, the embedded file is associated with a header than includes an instruction to generate a network system identifier (e.g., a cookie). The network system identifier may be stored by the computing device and later used to identify the computing device as a registrant for network access with the network provider. The embedded file may also be sent at other times, such as after authentication of the user for network access.

In order to control the use of physical radio resources, the physical radio resources are divided into chronologically consecutive frames (14), so that a frame contains slots (16, 17, 18) of various sizes, which slots represent a given share of the physical radio resources contained in the frame and can be individually allocated to different radio connections. The first dimension of a frame is time and the second dimension can be time, frequency or code. In the direction of the second dimension the slots represent various sizes, and a given first integral number of slots of the first size can be modularly replaced by another integral number of slots of another size. A certain number of consecutive frames form a superframe (19), in which case frames with corresponding locations in consecutive superframes are equal in slot division and allocations, if the data transmission demands do not change. Changes in the state of occupancy of the slots are possible at each superframe. In order to form an uplink connection, the mobile station sends a capacity request, where it indicates the type of requested connection and the demand of resources. In order to form a downlink connection, the base station subsystem sends a paging call, where it indicates the location in the superframe of the slots allocated to the connection. In order to indicate the state of occupancy, the base station subsystem maintains a superframe-size parametrized reservation table.
