Automatic and seamless vertical roaming between wireless local area network (WLAN) and wireless wide area network (WWAN) while maintaining an active voice or streaming data connection: systems, methods and program products

A Mobile Station (MS) is able to vertically roam in either direction between two different network, i.e. WWAN and WLAN. The MS is equipped with a dual mode Radio for WWAN and WLAN transmissions. The WLAN Radio is linked to a WLAN Enterprise Gateway Controller (EGC) via a first air link and the WWAN Radio is linked to a WWAN Base Transceiver Station (BTS) via a second air link. The EGC is connected to a Mobile Switching Center (MSC) which is in turn connected to the BTS. An outgoing VoIP call from the WLAN Radio to a remote party on the WWAN will transition or seamlessly switch over to a WWAN connection when the MS detects packet error rates, frequent scale back or consistent signal degradation. Upon such conditions, the WLAN Radio requests the EGC to request an Explicit Call Transfer via the MSC to the MS integrated WWAN Radio portion which automatically accepts the call based on referenced information stored in the user's subscriber identification module (SIM). Once the WWAN Radio is confirmed connected to the remote party on the WWAN, the WLAN Radio drops the WLAN connection. An incoming call between the MS and a remote user via the WWAN will transition to the WLAN Radio when the MS enters WLAN coverage. The MS issues an ECT to the WLAN. After user verification by the WLAN Radio and the EGC signals acceptance of the call, the WWAN Radio connection is dropped and the call is now established between the WLAN Radio and the remote party on the WWAN.

Method and apparatus for optimization of wireless multipoint electromagnetic communication networks

Exploiting the substantive reciprocity of internode channel responses through dynamic, adaptive modification of receive and transmit weights, enables locally enabled global optimization of a multipoint, wireless electromagnetic communications network of communication nodes. Each diversity-channel-capable node uses computationally efficient exploitation of pilot tone data and diversity-adaptive signal processing of the weightings and the signal to further convey optimization and channel information which promote local and thereby network-global efficiency. The preferred embodiment performs complex digital signal manipulation that includes a linear combining and linear distribution of the transmit and receive weights, the generation of piloting signals containing origination and destination node information, as well as interference-avoiding pseudorandom delay timing, and both symbol and multitione encoding, to gain the benefit of substantive orthogonality at the physical level without requiring actual substantive orthogonality at the physical level.

Integrating public and private network resources for optimized broadband wireless access and method

A system and method are disclosed for providing ubiquitous public network access to wireless, mobile terminals using private networks having private network access points and connections with the public network. The wireless, mobile terminals are permitted to use wireless, radio frequency communication devices comprising private network access points. A network access server (NAS) is associated with each wireless, radio frequency communication device and provides an interface between the wireless, mobile terminals and the private network. The NAS controls registration of wireless, mobile terminals as subscribers, and provides public network access to the mobile terminals through the private network's access point and public network connection. The NAS also restricts access by the mobile terminals to the private network, meters network useage by the mobile terminals, and controls use of bandwidth by the mobile terminals. The NAS also interfaces with integration operator distributed services over the public network. The integration operator services include databases and servers for storing and providing subscriber and network provider information for subscriber registration, network access and useage control, and accounting purposes. The NAS may be provided as a standalone element embodied in a computer, or may be integrated with the wireless radio frequency device and/or a network adaptor device for the private network.

Apparatus and method for delivering information to an individual based on location and/or time

A time/location information delivery system that provides focused advertising and/or other information to individuals based on the time and their location. A wireless identification device is carried by an individual and can be read from or written to when the individual passes by interrogators in a specific geographic location. The detectors read ID information embedded in the wireless identification device. A computer uses the ID and location information to select, from a list of information providers, those information providers which provide information content identifiable or correlated to a location and/or time, and is of interest to the individual. The information content can be forwarded to the individual by a variety of information channels. One channel uses conventional Internet email to deliver advertisements and other information to the individual's Internet mailbox. The email can be delivered to a conventional PC, a portable computer, a PDA, an intelligent telephone, pager or other suitable device. For ease of discussion, a pager and a PDA will be referred to collectively as a PDA. The wireless identification device can be an RFID tag embedded in a card, or even a wireless telephone. The RFID tag is read or written to by fixed interrogators and the location of the wireless telephone is detected by triangulating information from cell towers or by embedding the GPS receiver in the wireless telephone thereby providing the location information directly from the telephone. Of course, other nearly identical location determination means, such as quadrangulation could also be used. The location determination can be performed through similar means with other devices such as PDAs, laptops, pagers, etc.

Authenticating Wireless Person-to-Person Money Transfers

InactiveUS20070255662A1Facilitates manualFacilitates automated load functionalityDebit schemesLock-out/secrecy provisionWireless transmissionComputer science
A technique is used to ensure the authenticity of a wireless transmission source which is requesting a transaction to be performed by a system. The transaction may be a person-to-person money transfer or other value exchange transaction. The wireless transmission source may be a mobile phone or other similar device. The wireless transmission source transmits a key with the transaction request. The system will determine the authenticity of the transmission based on the transmitted key. If the transmission is determined to be authentic, the transaction will be acted upon. Various approaches for determining authenticity are discussed. The technique may also be used to prevent acting upon duplicate transmissions.

Method and apparatus for providing internet content to SMS-based wireless devices

A method and apparatus for providing hypermedia content maintained remotely on a network to a wireless device without a browser are described. A Short Message Service (SMS) request for Internet-based content is received from the wireless device at a proxy server, via an SMS Center (SMSC). The SMS request is transmitted to the SMSC on a wireless network. The proxy server transcodes the SMS request from a character set of the SMSC to a character set of an application and extracts a keyword from the trancoded request. The proxy server maintains a mapping of keywords to URLs. The proxy server looks up the extracted keyword in the keyword-to-URL mapping to identify the URL of an application associated with the keyword. The proxy server constructs an HTTP POST operation containing the keyword and the URL, and submits the HTTP POST operation to the application over a wireline network such as the Internet. Upon receiving an HTTP response containing the requested content from the application in response to the POST operation, the proxy server extracts the content from the HTTP response. The proxy server then translates the content from the content-type used by the application to the content-type used by the SMSC and transcodes the content from the character set used by the application to the character set used by the SMSC. The proxy server then sends the translated and transcoded content in an SMS response to the SMSC, for subsequent delivery to wireless device as an SMS message.
