A method performed in a cellular communication network for establishing that a first cell of said network is unable to receive uplink radio signals. The method comprises determining that no indicative radio message has been received from any radio device during a predetermined time period. In view of said determining, requesting a second cell, neighboring the first cell, to instruct at least one radio device, connected to said second cell and able to detect said first cell, to transmit a radio signal. The method may also comprise obtaining information about how to receive the radio signal. The method may also comprise determining that the radio signal was not successfully received by the first cell in accordance with the obtained information.

A system and method are provided for managing a queue of packets transmitted from a sender to a receiver across a communications network. The sender has a plurality of sender states and a queue manager situated in between the sender and receiver may have a corresponding plurality of queue manager states. The queue manager has one or more queue management parameters which may have distinct predetermined values for each of the queue manager states. When the queue manager detects an event that is; indicative of a change in the sender's state, the queue manager may change its sn tate correspondingly.
