Wireless communication device and method for transmission of services with different security levels

摘要

A communication device comprises an RF interface (20) and a CPU (10). The RF interface (20) has a physical channel PhCh to exchange radio messages on a wireless network. The physical channel PhCh is coupled with at least two logical channels LCi. The CPU (10) is connected to the RF interface (20) to provide at least two services Si on the wireless network. Each service Si is associated with a logical channel LCi of the RF interface (20). The CPU (10) associates a transmission parameter Pi with each service Si and sends the said transmission parameter Pi to the logical channel LCi associated with the service Si. The RF interface (20) configures the physical channel PhCh on the basis of the transmission parameter Pi depending on the logical channel LCi under transmission.

1. A communication method of a communicating device comprising a radiofrequency communication interface and a central processing unit, the radiofrequency communication interface having at least one physical channel to exchange radio messages on a wireless network and having means to multiplex at least two logical channels in the at least one physical channel, the central processing unit being connected to the radiofrequency communication interface to provide at least two services on the wireless network, each of the at least two services being associated with a distinct logical channel of the at least two logical channels of the radiofrequency communication interface, the communication method comprising:
for each service of the at least two services:
associating, by the central processing unit, a transmission parameter with the service, wherein the transmission parameter limits a transmission range for services using confidential data;transmitting, by the central processing unit, the transmission parameter, corresponding to the service, to the distinct logical channel associated with the service; andconfiguring, by the radiofrequency communication interface, the at least one physical channel depending on the transmission parameter being transmitted and on the distinct logical channel.
