Abstract: Methods and apparatus, including computer program products, are provided for configuring bearers for background traffic. In some exemplary embodiments, there is provided a method. The method may include processing parameters defining at least a first bearer and a second bearer, the first bearer and the second bearer established for a service at a processor; sending, based on at least the first bearer, traffic generated by the service, when at least one of the service and the processor is not in a background mode; and sending, based on at least the second bearer, background traffic generated by the service, when at least one of the service and the processor is in the background mode. Related apparatus, systems, methods, and articles are also described.

Abstract: An apparatus and method for attaching a wireless device to a wireless network. The apparatus comprises a processor arranged to, responsive to receipt of a reject message from a network control apparatus, cause the wireless device to: transmit a first attach request to the network control apparatus using a first communication layer and an existing connection between the wireless device and the network control apparatus; and responsive to a notification of a failure of the first attach request originating from a second communication layer which is lower than the first communication layer, transmit a second attach request to the network control apparatus using the first communication layer and a new connection between the wireless device and the network control apparatus, wherein transmission of the second attach request is effected independently of a timer started on receipt of the notification of a failure.
