Communication system comprising master and slave handheld apparatuses
View Patent ↗The invention relates to a communication system comprising:—a master handheld apparatus ( 100 ) comprising a first near field communication device a first wireless communication device, a current session being held by the master handheld apparatus ( 100 ), a slave handheld apparatus ( 130 ) comprising a second near field communication device and a second wireless communication device, the first and second near field communication devices being adapted to exchange identification information when they are held next to each other so as to initiate a communication link ( 140 ) between the first and second wireless communication devices, the first and second wireless communication devices then enabling the slave handheld apparatus ( 130 ) to join the current session through the communication link ( 140 ).
1. A communication system comprising:
a master handheld apparatus comprising a first Near Field Communication (NFC) device and a first wireless communication device, a current session being held by said master handheld apparatus,
a slave handheld apparatus comprising a second NFC device and a second wireless communication device, the first and second NFC devices exchanging identification information when they are held next to each other so as to initiate a communication link between the first and second wireless communication devices, said first and second wireless communication devices then enabling the slave handheld apparatus to join the current session through the communication link, wherein at least one of the master handheld apparatus and the slave handheld apparatus selects a most probable service from a given list of one or more available services.
2. The communication system of claim 1 , wherein the current session is a pre-established call placed between the master handheld apparatus and a remote communication apparatus over a communication network.
3. The communication system of claim 1 , wherein the first and second wireless communication devices comprise a BLUETOOTH™ or a Wi-fi transmitting/receiving interface.
4. The communication system of claim 1 , wherein each of the master handheld apparatus and the slave handheld apparatus initiates the communication link by selecting a most probable service from a given list of one or more available services.
5. The communication system of claim 1 , wherein at least one of the master and the slave handheld apparatus maintain a service registration table identifying available services and detect that the most probable service cannot be executed, and the master handheld apparatus updates the services registration table in response to detecting that the most probable service cannot be executed.
6. A slave handheld apparatus for joining a current session held by a master handheld apparatus comprising a first Near Field Communication (NFC) device and a first wireless communication device, said slave handheld apparatus comprising:
a second NFC device and
a second wireless communication device, the second NFC device exchanging identification information with the first NFC device when they are held next to each other so as to initiate a communication link between the first and second wireless communication devices, said first and second wireless communication devices then enabling the slave handheld apparatus to join the current session through the communication link, wherein the slave handheld apparatus initiates the communication link by selecting a most probable service from a given list of one or more available services.
7. The slave handheld apparatus of claim 5 , further comprising
a memory for storing context parameters associated with the slave handheld apparatus, said context parameters defining data to be transmitted over the communication link, the current session being joined as a function of the context parameters.
8. The slave handheld apparatus of claim 6 , wherein the first and second wireless communication devices comprise either a BLUETOOTH™ or a Wi-Fi transmitting/receiving interface.
9. A master handheld apparatus comprising:
a first Near Field Communication (NFC) device and
a first wireless communication device, said master handheld apparatus being suitable for communicating with a slave handheld apparatus comprising a second NFC device and a second wireless communication device, a current session being held by said master handheld apparatus, wherein the first NFC device is exchanges identification information with the second NFC device when they are held next to each other so as to initiate a communication link between the first and second wireless communication devices, said first and second wireless communication devices then enabling the slave handheld apparatus to join the current session through the communication link, and wherein the master handheld apparatus initiates the communication link by selecting a most probable service from a given list of one or more available services.
10. The master handheld apparatus of claim 9 , wherein the current session is a pre-established call placed between the master handheld apparatus and a remote communication apparatus over a communication network.
11. The master handheld apparatus of claim 9 , wherein the first and second wireless communication devices comprise either a BLUETOOTH™ or a Wi-Fi transmitting/receiving interface.
12. The master handheld apparatus of claim 9 , wherein the master handheld apparatus maintains a service registration table identifying available services and detects that the most probable service cannot be executed and updates the service registration table in response to detecting that the most probable service cannot be executed.
13. A communication method between a master handheld apparatus comprising a first Near Field Communication (NFC) device and a first wireless communication device, and a slave handheld apparatus comprising a second NFC device and a second wireless communication device, a current session being held by said master handheld apparatus, the method comprising:
exchanging identification information between the first and second NFC devices when they are held next to each other;
initiating a communication link between the first and second wireless communication devices; and
enabling the slave handheld apparatus to join the current session through the communication link, wherein at least one of the master handheld apparatus and the slave handheld apparatus selects a most probable service from a given list of one or more available services.
14. The method of claim 13 , wherein the current session is a pre-established call placed between the master handheld apparatus and a remote communication apparatus over a communication network.
15. The method of claim 13 , wherein the first and second wireless communication devices comprise either a BLUETOOTH™ or a Wi-Fi transmitting/receiving interface.
16. The method of claim 13 , further comprising:
storing, in at least one of the master and the slave handheld apparatus, a service registration table identifying the available services,
wherein said initiating a communication link further includes:
said at least one of the master and the slave handheld apparatus selecting the most probable service from its stored service registration table,
detecting whether the most probable service can be executed, and in response to detecting that the most probable service cannot be detected, updating said registration table.
