Enhanced wireless handset, including direct handset-to-handset communication mode
View Patent ↗A wireless handset is provided with enhanced features and capabilities. The wireless handset may be embodied as a full-featured handset that is capable of operating either within a wireless network (such as a cellular or PCS network) or in a direct handset-to-handset communication mode that is independent of the wireless network. Alternatively, the wireless handset may be embodied as a special purpose handset, that is capable of simply operating in a direct handset-to-handset communication mode. The wireless handset may additionally include features for supporting and enhancing direct communication between handsets. Such features may include a find feature that permits a user to determine which objects, including other wireless handset users, are located within a predetermined operating range of the wireless handset. A memorize feature may also be provided to permit handsets and other objects exchange information by wireless transmission.
1. A method for short-range wireless communication by an apparatus, the method comprising:
transmitting, by a transceiver in the apparatus, a message to an object over a time slotted channel of a wireless network, wherein the object is within a short-range wireless communication area of the apparatus and the apparatus is operating in a short-range messaging state;
transmitting, by the transceiver, an inquiry message to two or more other objects from the apparatus to determine whether it is within the short-range wireless communication area of the apparatus, wherein the inquiry message is communicated via another time slotted channel of the wireless network within the short-range wireless communication area of the apparatus and the apparatus stays in communication with the object; and
receiving, by the transceiver in the apparatus, a response message from at least one of the two or more other objects to the inquiry message via the another time slotted channel of the wireless network if the at least one of the two or more other objects is set to respond.
2. The method of claim 1 , wherein the apparatus, object, and the two or more other objects are mobile telephones.
3. The method of claim 1 , further comprising:
generating a list by the apparatus that includes the at least one of the two or more other objects based on the receiving the response message therefrom; and
displaying the list identifying the at least one of the two or more other objects using a graphical user interface.
4. The method of claim 1 , further comprising:
receiving, by the transceiver, a different inquiry message from a different object; and
responding to the different inquiry message if the apparatus is set to respond.
5. The method of claim 1 , wherein the receiving comprises receiving the response message from the at least one of the two or more other objects via the another time slotted channel if user authorization is provided by the at least one of the two or more other objects.
6. The method of claim 1 , wherein the receiving comprises choosing a selected channel for further communication with the at least one of the two or more other objects.
7. The method of claim 1 , wherein the another time slotted channel is a control channel that is accessed for a predetermined period of time.
8. The method of claim 1 , further comprising communicating by the apparatus with the at least one of the two or more other objects subsequent to a security procedure requiring user input.
9. The method of claim 1 , further comprising downloading data by the apparatus from the at least one of the two or more other objects to the apparatus.
10. The method of claim 1 , wherein the time slotted channel and the another time slotted channel each comprise two or more frequencies.
11. An apparatus for short-range wireless communication, the apparatus comprising:
a transceiver configured to:
transmit a message to an object over a time slotted channel of a wireless network, wherein the object is within a short-range wireless communication area of the apparatus and the apparatus is operating in a short-range messaging state;
transmit an inquiry message to two or more other objects from the apparatus to determine whether it is within the short-range wireless communication area of the apparatus, wherein the inquiry message is communicated via another time slotted channel of the wireless network within the short-range wireless communication area of the apparatus and the apparatus is configured to stay in communication with the object; and
receive a response message from at least one of the two or more other objects to the inquiry message via the another time slotted channel of the wireless network if the at least one of the two or more other objects is set to respond; and
at least one antenna coupled to the transceiver.
12. The apparatus of claim 11 , wherein the apparatus is a mobile telephone.
13. The apparatus of claim 11 , further comprising:
circuitry configured to generate a list that includes the at least one of the two or more other objects based on the receiving the response message therefrom; and
circuitry configured to display the list identifying the at least one of the two or more other objects using a graphical user interface.
14. The apparatus of claim 11 , wherein the transceiver is further configured to:
receive a different inquiry message from a different object; and
respond to the different inquiry message if the apparatus is set to respond.
15. The apparatus of claim 11 , wherein the transceiver is further configured to receive the response message from the at least one of the two or more other objects via the another time slotted channel if user authorization is provided by the at least one of the two or more other objects.
16. The apparatus of claim 11 , wherein the transceiver is further configured to receive further comprises choosing a selected channel for further communication with the at least one of the two or more other objects.
17. The apparatus of claim 11 , wherein the another time slotted channel is a control channel that is accessed for a predetermined period of time.
18. The apparatus of claim 11 , wherein the transceiver is further configured to communicate by the apparatus with the at least one of the two or more other objects subsequent to a security procedure requiring user input.
19. The apparatus of claim 11 , wherein the transceiver is further configured to download data from the at least one of the two or more other objects to the apparatus.
20. The apparatus of claim 11 , wherein the time slotted channel and the another time slotted channel each comprise two or more frequencies.
