A location system is disclosed for commercial wireless telecommunication infrastructures. The system is an end-to-end solution having one or more location centers for outputting requested locations of commercially available handsets or mobile stations (MS) based on, e.g., CDMA, AMPS, NAMPS or TDMA communication standards, for processing both local MS location requests and more global MS location requests via, e.g., Internet communication between a distributed network of location centers. The system uses a plurality of MS locating technologies including those based on: (1) two-way TOA and TDOA; (2) pattern recognition; (3) distributed antenna provisioning; (5) GPS signals, (6) angle of arrival, (7) super resolution enhancements, and (8) supplemental information from various types of very low cost non-infrastructure base stations for communicating via a typical commercial wireless base station infrastructure or a public telephone switching network. Accordingly, the traditional MS location difficulties, such as multipath, poor location accuracy and poor coverage are alleviated via such technologies in combination with strategies for: (a) automatically adapting and calibrating system performance according to environmental and geographical changes; (b) automatically capturing location signal data for continual enhancement of a self-maintaining historical data base retaining predictive location signal data; (c) evaluating MS locations according to both heuristics and constraints related to, e.g., terrain, MS velocity and MS path extrapolation from tracking and (d) adjusting likely MS locations adaptively and statistically so that the system becomes progressively more comprehensive and accurate. Further, the system can be modularly configured for use in location signing environments ranging from urban, dense urban, suburban, rural, mountain to low traffic or isolated roadways. Accordingly, the system is useful for 911 emergency calls, tracking, routing, people and animal location including applications for confinement to and exclusion from certain areas.

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.

A wireless instant messaging system is disclosed. A mobile station (MS), such as a cellular telephone for instance, may be registered with an instant messaging (IM) server as being available to receive instant messages via an IM proxy. A user at an IM client terminal may then send an instant message destined for a user at the MS. The IM server may direct the message to a service node (SN), which may convert the message into an industry standard SMS message and send the SMS message to the MS. At the MS, a user may read the SMS message and engage a callback feature, which will establish a dial-up voice connection between the MS and the SN. The user at the MS may then speak an instant message response, and the SN may record the response as a compressed audio file. The SN may then send the compressed audio file as an attachment to an instant message back to the user at the IM client terminal. The IM client terminal may then play the spoken response message. The invention facilitates robust instant messaging communication, while avoiding the need for a user at the mobile station to engage in cumbersome text entry via a numeric keypad.

A method adapts scheduling priorities in a CDMA wireless communications system to conserve battery power in mobile terminals operating within the system. A base station, within the system, receives battery power level information and other setup information from mobile terminals operating within the service area of the base station during call setup procedures. Based on the battery power level information and other setup information, the base station adapts scheduling priorities for the mobile terminals to expedite wireless transmissions from those mobile terminals reporting low battery power levels. The base station schedules the transmissions from low battery power mobile stations to be clustered together in a low-power time slot which is separate in time from the scheduled transmissions from high battery power mobile stations. The base station transmits a power control message to the low battery power mobile stations, to reduce the transmission power required for those mobile stations during the low-power time slot.

A method and apparatus for obtaining information about an object through interaction between a mobile station (MS) and a computer network such as the Internet, and communicating the information to the MS. A digital camera obtains an image of an object, such as a geographic region proximate the MS, which is then transmitted through the mobile communications system to the computer network. A converter server such as an Optical Character Reader (OCR) server interfaced with the global computer network converts the digital image to a text format which is then compared, along with a general location identifier of the MS to geographic data stored in a location database connected to the global computer network. Based on a comparison of the converted text data and the general location identifier of the MS to the geographic data stored in the location server, a precise location of the MS is determined and transmitted to the MS.

A novel and useful apparatus for and method of coordinating the allocation of transmission and reception availability and / or unavailability periods for use in a communications device incorporating collocated multiple radios. The mechanism provide both centralized and distributed coordination to enable the coordination (e.g., to achieve coexistence) of multiple radio access communication devices (RACDs) collocated in a single device such as a mobile station. A distributed activity coordinator modifies the activity pattern of multiple RACDs. The activity pattern comprises a set of radio access specific modes of operation, (e.g., IEEE 802.16 Normal, Sleep, Scan or Idle modes, 3GPP GSM / EDGE operation mode (PTM, IDLE, Connected, DTM modes), etc.) and a compatible set of wake-up events, such as reception and transmission availability periods. To prevent interference and possible loss of data, a radio access is prevented from transmitting or receiving data packets while another radio access is transmitting or receiving. In the event two or more RATs desire to be active at the same time, the mechanism negotiates an availability pattern between the MS and a corresponding BS to achieve coordination between the RATs.
