Abstract: A method of communications in a cellular telecommunications network is disclosed. A cell update message is sent from a user equipment to a network node. The cell update message comprises a cell update cause. The cell update cause includes one of information indicating user data transmission or information indicating control data transmission, if the cause of the cell update is a uplink data transmission. A first procedure is used for data transmission if said information is user data transmission. A different second procedure is used for data transmission if said information is control data transmission.

Abstract: A method and a network element for determining cell-based values of a parameter of a selected active uplink transport channel multiplexed with other transport channels to a dedicated physical channel. It is proposed that a value for the parameter of the selected uplink transport channel is computed in predetermined periods of time based on the value of at least one available parameter associated to the dedicated physical channel. Further it is determined for the predetermined periods of time for each of the transport channels whether it is active in the respective period of time. Those periods of time for which it was determined that any other than the selected transport channel was active are excluded from supplying a relevant value for the parameter of the selected active uplink transport channel.

Abstract: This invention concerns a method for controlling at least one radio bearer parameter of a first radio bearer (RB), and a Radio Bearer Control unit. The invention introduces a continuous monitoring and controlling of the RAB-RB parameter mapping for new and for already active connections. According to the invention a method for controlling at least one radio bearer parameter of a first radio bearer (RB) to be established or maintained between a mobile terminal and a first access-network node in a first cell of a cellular radio access network is provided. The first access-network node communicates with a core-network node in a core network to establish or maintain at least one radio access bearer (RAB) between the mobile terminal and the core-network node.
