Traffic notification systems include a location determination system that can determine a geographic location of a subscriber, and an automated traffic notification system that can automatically transmit a traffic notification message that is based on the geographic location of the subscriber to a wireless terminal associated with the subscriber.

Automated location-intelligent traffic notification service systems and methods

Electronic messages such as pages are exchanged between a user device and a message service using one of multiple wireless communication networks. The wireless communication networks may include mobile and/or fixed wireless networks. The user device registers with the message service through at least one of the wireless communications networks. The user device may register through multiple wireless communication devices when available. The user device sends messages through the wireless network through which registration has been established and may apply rules to choose when registration has occurred via multiple wireless networks.

Electronic message exchange over multiple wireless communication networks with a single device

Traffic notification systems include a location determination system that is configured to determine a geographic location of a subscriber and an automated traffic notification system that is configured to automatically transmit a traffic notification message that is based on the geographic location of the subscriber to a wireless.

A telephone and a method for routing a telephone call using the telephone is provided. The telephone includes a microprocessor and a transceiver coupled to the microprocessor. The telephone further includes a voice recognition unit coupled to the microprocessor. The unit is further configured to determine when the user is speaking proximate the unit and to generate a match signal when the user is speaking. The microprocessor is configured to generate a command signal to induce the transceiver to transmit a voice mailbox routing signal to a telephone switching center upon receipt of the match signal from the unit.

Telephone and method for routing a telephone call in a telecommunications network

A method and system for determining the three-dimensional location of a mobile wireless device. In one implementation, the device is a cellular telephone making a 911 call from one floor of a multi-story building. An embodiment of the method of the invention includes establishing a database that associates transmission metrics with altitudes of x-y coordinate locations having more than one altitude at which the mobile wireless device could be located, receiving a communication from the mobile wireless device, determining an x-y coordinate location of the mobile wireless device, measuring a transmission metric of the mobile wireless device, and consulting the database to determine the altitude from the x-y coordinate location and the measured transmission metric. The transmission metric could be, for example, the transmission time or angle of arrival of a wireless signal received from the mobile wireless device.

Traffic notification systems include a location determination system that is configured to determine a geographic location of a subscriber and an automated traffic notification system that is configured to automatically transmit a traffic notification message that is based on the geographic location of the subscriber to a wireless terminal that is associated with the subscriber.

A mobile user request for a location of a wireless network access point can be received via a user terminal. A geographic location of the mobile user can be identified responsive to the user request. A wireless network access point convenient to the user location can be identified.
