摘要： A technique is provided for use by a Multi-Radio Management Resource (MRRM) component of a multi-radio wireless communication system for controlling the handover of a mobile terminal between different radio access technologies (RAT). In one example, all suitable RATs having coverage areas currently covering the location of a mobile terminal are identified. The performance gain that might be achieved via a handover to one of the other RATs is then determined by the MRRM based on various performance gain factors. Handover costs that will be incurred as a result of the handover are also explicitly calculated. Then, a cost-adjusted gain is determined by the MRRM based on the performance gain and the handover costs. A handover is only triggered by the MRRM if the cost-adjusted gain exceeds a minimum threshold. The speed and trajectory of the mobile terminal may also be considered.

摘要： A technique of configuring link layer entities for a handover is described. In a method embodiment, the technique includes receiving from a recipient of protocol data units a supplemental status report for an existing ARQ connection in context with an imminent handover, determining service data units corresponding to buffered protocol data units taking into account information included in the supplemental report, and transferring the determined service data units to a link layer entity which is to establish a new ARQ connection to the recipient. The forced status synchronization that is based on the supplemental report prevents the transfer of service data units that have already been successfully received at the recipient.

摘要： User-networks having more than one type of access system are connected to networks having multi-access technology. Interference is measured between the connected, active access systems and the active systems are prioritized. A priority value is assigned to each of the active access systems based on the interference between systems. According to the assigned priority value, the access system with the highest value is enabled. Remaining systems are then compared with the enabled access system and an interference threshold. If the level of interference exceeds the threshold, the offending access system is disabled. If the threshold is not exceeded, the number of simultaneously operating access systems is compared to a predetermined number and the access systems below that number are then disabled.
