Abstract:
In a wireless local area network (LAN), such as one that is compatible with the HIPERLAN 2 standard, scheduling of long channel (LCH) PDUs and short channel (SCH) PDUs is based on an awareness of desired ARQ response time. Accordingly, mobile terminals and access points, particularly those that are communicating over time critical connections, are afforded a maximum amount of time to generate ARQ messages, while still achieving a fast response time. For example, in the more likely scenario where the uplink channel (ULCH) precedes the downlink channel (DLCH) in the Medium Access Control (MAC) data frame, the amount of time needed to generate an ARQ message may be maximized by scheduling the SCHs associated with a given connection so that they follow the corresponding LCHs in the ULCH of the MAC frame, and where the SCHs precede the corresponding LCHs in the DLCH of the MAC frame.
Abstract:
The invention relates to a method, by a policy control unit (100) of a mobile communications network, to control a signalling of congestion information of mobile entities at a plurality of congestion monitoring units (200) which monitor which mobile entities are affected by a congestion state in a radio access network (10) of the mobile communications network, the method comprising the steps of receiving, from one of the congestion monitoring units, an indication that one of the mobile entities is affected by a congestion state, storing said one congestion monitoring unit from which the indication is received as the current congestion monitoring unit for said one mobile entity, receiving, from another congestion monitoring unit, the indication that said one mobile entity is affected by a congestion state, indicating, in response to the indication received from the other monitoring unit, to the current congestion monitoring unit a release of congestion information relating to said one mobile entity.
