DIRECTIONAL NAVIGATION WITH MOBILE AND FIXED-LOCATION DEVICE INTERNET QUERY INITIATION
A mobile wireless network and a method of operation provide directional assistance in response to an Internet query. The directional assistance is provided from a location of the querying device to a destination that may be selectively prompted based on whether the destination is a nearby business, a type of business, a street address, or another mobile device or fixed telephone location. An indication of location of the querying device is also selectively obtained depending on whether the querying device is a wireless device such as a mobile telephone, or whether the device has a presumed fixed location, such as an ordinary telephone connected to a public-switched telephone network (PSTN).
