Extended cellular telephony protocol

摘要

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.
