Extended cellular telephony protocol
First Claim
1. A method supporting roaming of a mobile unit between a first network in which multiple devices belonging to a defined set communicate with each other according to a first protocol, wherein the first protocol is a Bluetooth protocol and a second network that provides wireless connectivity according to a cellular telephony protocol, the mobile unit being capable of operation according to the first protocol and the cellular telephony protocol, the method comprising:
- receiving a voice packet for transmission over at least one radio bearer between at least two devices in the first network, said at least one radio bearer being established according to the first protocol and the voice packet conforming to the cellular telephony protocol;
appending a header to the voice packet so that a cellular control stack controls processing of the voice packet according to the first protocol when a field of the header comprises a first value and the cellular control stack controls processing of the voice packet according to cellular telephony protocol when the field of the header comprises a second value different than the first value; and
transmitting the voice packet using said at least one radio bearer.

Abstract
The present invention provides a method for transmitting voice packet data over a selected one of a first network in which multiple devices belonging to a defined set communicate with each other according to a first protocol and a second network in which multiple devices communicate with each other according to a second protocol, different from the first protocol. The method includes establishing at least one radio bearer between at least two devices in the first network according to the first protocol, receiving at least one voice packet that conforms to the second protocol, modifying the at least one voice packet to conform to the first and the second protocols, and transmitting the at least one modified voice packet using the at least one radio bearer.

6. A method for transmitting voice packet data over a selected one of a piconet in which multiple Bluetooth-enabled devices within a defined set communicate with each other by exchanging messages with a master device within the set using a Bluetooth protocol and a cellular wireless network in which mobile units and base stations exchange messages according to a cellular telephony protocol, the method comprising:
-
receiving a voice packet for transmission over at least one radio bearer between at least two devices in the piconet, said at least one radio bearer being established according to the Bluetooth protocol and the voice packet conforming to the cellular telephony protocol; appending a header to the voice packet so that a cellular control stack can control processing of the voice packet according to the Bluetooth protocol when a field of the header comprises a first value and the cellular control stack controls processing of the voice packet according to cellular telephony protocol when the field of the header comprises a second value different than the first value; and transmitting the voice packet using said at least one radio bearer. - View Dependent Claims (7, 8, 9, 10, 11, 12)

13. A method for wireless telecommunications using a first network in which multiple devices belonging to a defined set communicate with each other according to a first protocol wherein the first protocol is a Bluetooth protocol and a second network in which multiple devices communicate with each other according to a second protocol wherein the second protocol is a cellular telephony protocol, the method comprising:
forming a wireless telecommunications link between a first device configured to send and receive messages according to the first protocol and a second device configured to send and receive messages according to the second protocol, the wireless telecommunications link comprising a portion that operates according to the first protocol and a portion that operates according to the second protocol, and wherein the messages sent over the wireless communication link between the first and second devices comprise a header, and wherein a cellular control stack controls processing of the messages according to the first protocol when a field of the header comprises a first value and the cellular control stack controls processing of the messages according to the second protocol when the field of the header comprises a second value different than the first value. - View Dependent Claims (14, 15, 16, 17)

18. A method for wireless telecommunications using a piconet in which multiple Bluetooth-enabled devices within a defined set communicate with each other by exchanging messages with a master device within the set using a Bluetooth protocol and a cellular wireless network in which mobile units and base stations exchange messages according to a cellular telephony protocol, the method comprising:
forming a random access channel between a first device configured to send and receive messages according to the Bluetooth protocol and a second device configured to send and receive messages according to the cellular telephony protocol, the random access channel comprising a portion that operates according to the Bluetooth protocol and a portion that operates according to the cellular telephony protocol, and wherein the messages sent over the random access channels between the first and second devices comprise a header, and a cellular control stack controls processing of the messages according to the Bluetooth protocol when a field of the header comprises a first value and the cellular control stack controls processing of the messages according to the cellular telephony protocol when the field of the header comprises a second value different than the first value. - View Dependent Claims (19, 20, 21, 22)
