  • Controlling channel switching in a UMTS network
    Patent number: 7099622
    Abstract: In a UMTS Terrestrial Radio Access Network (UTRAN), a method of switching from a current common channel to a dedicated channel for a UE. The method comprises estimating the round trip delay for data packets travelling between the UE and a peer node with which the UE is communicating. The product of the estimated round trip delay and the bandwidth of the common channel or the dedicated channel is determined and a threshold defined on the basis of that product. A switch from the common channel to a dedicated channel is initiated when the fill level of the RLC buffer(s) in the UTRAN for the UE reaches or exceeds said threshold.

  • Method of and equipment for performing radio communication in a plurality of radio communication environments
    Patent number: 7092710
    Abstract: A method of and equipment for performing radio communication (7) between a fixed radio access unit (5, 10, 13, 15) and a remote portable radio telecommunication unit (8) arranged for operating in accordance with a predetermined radio communication standard, such as Digital Enhanced Cordless Telecommunications (DECT), in a plurality of radio communication environments such as in the home (2), in the office (3) and/or in the public domain (4). For each radio environment (2, 3, 4) operational parmeter settings are obtained associated with system operation efficiency and communication quality of a particular environment (2, 3, 4). Radio communication (7) is performed with the operational parameter settings selected in accordance with the applicable radio environment (2, 3, 4).
