Abstract: A method for deciding on the activation of carrier aggregation across first and second base stations of a cellular network for delivering a service to a mobile terminal is provided. The decision is made on the basis of a combination of a plurality of parameters. One parameter is associated with a performance of the cellular network. One parameter is associated with a Quality of Service requirement of the service. One parameter is associated with a state of the mobile terminal and/or a subscriber associated with the mobile terminal. One parameter is associated with a radio link between the mobile terminal and the first base station and/or second base station.

Abstract: A method for selecting a mode of service delivery to a mobile terminal using carrier aggregation across first and second base stations of a cellular network is provided. The selection being based on one or more of: a parameter of the service; and a parameter of the network architecture.

Abstract: Methods and apparatus are provided for management, control and optimisation of a telecommunications network based on user experience policies that define user experience for one or more service(s) provided over a telecommunications network including one or more network nodes. The methods and apparatus make user experience measurements in the telecommunications network to ensure that the user experience policies are being met for user equipment and corresponding users in the network that use the one or more service(s). The methods and apparatus automatically changes certain parameters or adjusts the one or more network nodes in the network using one or more network performance mechanisms if the user experience policies associated with one or more users are not being met. The network continues to monitor the user experience measurements and, if necessary, change or adjust the network node(s), to ensure that user experience policies continue to be met.
