  • Transport channel control in a UMTS network
    Patent number: 7194267
    Abstract: A method of switching from a first to a second transport channel for User Equipment (UE) in a UMTS Terrestrial Radio Access Network (UTRAN) of a UMTS system. The method comprises initiating a channel switch, and initiating a synchronisation of the UE to the second channel. The first channel is maintained during the synchronisation phase such that data may be sent between the UE and UTRAN over the first channel during synchronisation. The first channel is terminated only after synchronisation of the UE to the second channel has been achieved.

  • Packet transmission in a UMTS network
    Patent number: 6901065
    Abstract: A method of scheduling packets for transmission over the air interface of a UMTS Terrestrial Radio Access Network (UTRAN) in the case where a pair of Radio Network Controllers (RNCs) are acting as separate serving and controlling (drift) RNCs for a mobile terminal. The method comprises sending from the controlling RNC to the serving RNC, allocated scheduling priorities together with packet sizes accepted for transmission with those priorities by the controlling RNC. Subsequently the serving RNC send to the controlling RNC, packets of sizes accepted by the serving RNC together with respective allocated priorities.
