Abstract: The present invention provides event-based or driven reporting of mobile station measurements. A mobile station measures one or more radio-related parameters for one or more cells in a radio access network. The mobile station evaluates the measured radio-related parameter with respect to a predetermined condition or event and determines that the predetermined condition is satisfied or that the event has occurred. Based on that evaluation, the mobile radio sends a report to the radio access network. Accordingly, the occurrence of an event and/or the satisfaction of a condition triggers the sending of the report to the network. That way, the network receives the information so that it can take timely and appropriate action without sending outdated or redundant measurement reports that do not convey relevant or new information.

Abstract: A serving RNC signals the load contribution of all mobiles for which it is the serving RNC to all cells controlled by another RNC that are affected by the uplink transmissions of those mobiles. This allows the other RNC to determine the contribution of those mobiles to the total uplink interference in its cells. In one example, the uplink load maybe estimated using mobile-based path gain measurements.

Abstract: In a UMTS communication system, packets of data are routed from a core network 2 to user equipment 6 (and vice versa) through a radio network controller 4 and associated base station 5. To reduce delay, the ARQ (Automatic Repetition reQuest) mechanism may take place in the base station and UE rather than the RNC and UE. This may lead to problems when UE is in soft handover between two base stations as one of the base stations may receive ACK or NACK signals from the UE for packets which have not yet been transmitted. To mitigate this, there needs to be some sort of synchronisation between the transmission buffers of the two base stations. This is achieved by shifting the transmission window of the base stations so that its lower region covers the packet having the lowest sequence number for which an ARQ has not yet been received. For a UE transmitting to plural base stations and receiving conflicting ARQ messages, the UE may respond to ARQ messages from the BS until a Secure Data Unit has been acknowledged by the BS. In response to ARQ messages from a BS the UE may retransmit packets to all base stations simultaneously until at least one BS has acknowledged a complete Secure Data Unit. A soft handover method is also disclosed.
