| 摘要 |
<p>The invention relates to a cellular radio system and a method of cyphering data transmission in a radio system that comprises at least one transceiver (102) communicating with other transceivers (108) on a radio connection (116) including one or more parallel radio bearers or logical channels, ciphering being performed on said bearers or logical channels using selected ciphering method parameters. Ciphering is performed on said bearers using selected ciphering method parameters. To ensure diverse and efficient ciphering, different ciphering method parameters can be used on each parallel radio bearer (116).</p> |
