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.

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.

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.

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.

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.
