|20100284378||Method for packet classification based on the protocol type and on priorities - External packets entering a transmitting entity of a broadband wireless access system are forwarded to a receiving entity onto MAC layer connections at the wireless interface between such entities in a manner depending on the result of a packet classification performed by using a set of classification rules identified by a rule index and associated with a priority index determining the order of application of different rules to packets relating to a same service. The classification rules include both classification rules specific for data communication protocols and containing one or more protocol-specific parameters to be matched by corresponding fields in a packet being classified, and a pass-through classification rule only containing a priority index and a rule index, but no protocol-specific matching parameter, said pass through classification rule being applied to a packet not having matched a protocol-specific classification rule.||11-11-2010|
|20100034087||Controlling congestion detection in hsdpa systems - A method controls transport network layer congestion detection in HSDPA systems. The method involves detecting, at an SRNC, a condition requiring the disabling, at a Node B, of measurements performed on certain fields of a data frame for detecting congestion for certain packet flows; sending, from the SRNC to the Node B, a command for disabling said measurements for the concerned packet flows; and resetting, at the Node B, any measurement performed until reception of said command for disabling the congestion detection.||02-11-2010|
|20090274118||METHOD FOR PREVENTING PIN-PONG HANDOVER EFFECT IN MOBILE WIMAX NETWORKS - To prevent a handover ping-pong effect between base-station in WiMAX-compliant networks, a priority level is firstly assigned to the trigger causes for handover, and the prioritized causes are coded. Then codes are subdivided into a first class of unrestricted handovers and a second class of handover subjected to restriction. The first class includes the highest priority handovers. The second class includes a given subset of handovers with a high or normal priority intended for optimizing resources. Outside this subset the second class also includes handovers for power budget having a normal priority level. When an outgoing handover is decided, the actual serving BS either permits or selectively suppresses the Handover Request to the target BS when the latter is corresponding to the preceding serving BS for that mobile. The selection mechanism operates on the second class of restricted handovers, during a penalty time triggered by the occurrence of handover causes included in the given subset of the second class.||11-05-2009|
