20090017823 | TECHNIQUE FOR CONTROLLING HANDOVERS WITHIN A MULTI-RADIO WIRELESS COMMUNICATION SYSTEM - 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. | 01-15-2009 |

20090175172 | Method and Arrangement for Route Cost Determination and Selection with Link Cost Interaction - This invention extends routing mechanisms that use link metrics for route selection so that: A link metric cross correlation vector is determined for all links, where each element in the vector corresponds to some other link, and reflects the change in the link metric value if a data flow would already use this other link. The invention further describes a specific embodiment where all cross-correlating links are adjacent to each other, i.e., they terminate or originate in a common node. A mechanism is described to create an extended routing graph. This extended graph permits the use of standard polynomial time algorithms that simultaneously construct the optimal route and find the optimal route metric (such as shortest-path algorithms) also for the adjacent link cross-correlating case. | 07-09-2009 |

The access selection comprises an Access determination and an Access configuration. In a first step a Generic Link Layer Entity (GLL) determines one or more Generic Performance Metrics (GPM) corresponding to one or more configurations of the Access (A). The Generic Link Layer Entity (GLL) sends the determined one or more Generic Performance Metrics (GPM) corresponding to one or more configurations of the access (A) to the Multi Access Management entity (MAM). The Multi Access Management entity (MAM) determines from received Generic Performance Metrics (GPM), which Access (A) offers a configuration (GPM), which is suited for an application/bearer requirements. Then, said Multi Access Management entity (MAM) sends the determined configuration to the Generic Link Layer Entity (GLL) associated to the determined Access (A). The determined Generic Link Layer Entity (GLL) configures the Access (A) based on the determined configuration received from the Multi Access Management entity (MAM). Furthermore, the invention relates to corresponding devices, modules and software. | 10-29-2009 |
