Abstract: Delivery of protocol data units or other suitable data or information units in various communication systems can be enhanced by appropriate methods and devices. For example, in-sequence delivery of protocol data units received in parallel from several lower-layer acknowledged-mode protocol entities may benefit from timers and/or forwarding status reports. A method can include observing a gap in a sequence of protocol data units received from a plurality of lower-layer protocol entities providing data transfer. The method can also include starting a timer upon the gap observation. The method can further include preventing the gap from blocking delivery of service data units to a higher layer, when the timer expires. The method can additionally include detecting a forwarding-status report. The method can also include immediately proceeding with data delivery to higher layer, containing the gaps because of the lack of forwarding at handover.

Abstract: Content service(s) to device(s) is provided. Availability of broadcast transmission of said content is determined after an indication is signaled that a dedicated unicast radio bearer is needed/is not needed for reception of said. Subsequent to reception of the indication the content is transmitted over a dedicated unicast radio bearer or broadcasting. Transmission of the content can be supported by an indication of a need for a continued network connection for the device even when the amount of unicast traffic over the connection in a core network does not justify maintenance of the connection to cause the core network to refrain from releasing said network connection. Unicasting of content to a device moving from a first to a second cell can be continued based on signaling of a message to a control entity of a second cell, the message providing information of the identity of the service(s).

Abstract: Method and apparatus for reception of data units in a device by means of a first protocol and a second protocol are disclosed. A control function of the second protocol is informed of interruption in a control function of the first protocol. In response thereto a reordering timer of the second protocol is considered as having expired, and a state variable of the second protocol is updated to equal with a highest received state variable.

At least a first carrier towards the terminal is established from the at least one another device and at least a second carrier is established towards the terminal from the device. A control module of the device is configured to suspend ongoing traffic between the device and the terminal on the second carrier, perform re-establishment of one or more protocol entities communicating over bearers between the device and the terminal on the second carrier, and resume traffic between the device and the terminal on the second carrier. The suspending is triggered by a first instruction received from a first one of the at least one another device, and the resuming is triggered by a second instruction received.

The device receives a report indicative of a connection quality of the first carrier, responsive thereto issues a request for handover of the first carrier towards a second device, sends relocation information in relation to the first carrier towards the first other device, and only after sending that relocation information, commands the terminal to perform a handover of the first carrier to the second device. Such device, in cooperation with other devices, accomplishes an optimized handover in terms of a primary component carrier relocation from a serving eNB towards a target eNB, while a secondary component carrier is maintained.
