Disclosed are a method and system for an intermediate node, which negotiates a Quality of Service (QoS) contract with two or more secondary nodes, to maintain a record of previous contract agreements to use as the basis for future contracts and to select the negotiation order with the secondary nodes based on a configurable rule set. The intermediate node selects the secondary node which is deemed to be (predicted as) most restrictive to begin QoS negotiations. The intermediate node dynamically creates for a specific user a new QoS profile to begin the QoS negotiations based on current system loading and historical QoS precedents.

A method is performed in a mobile device for selecting or excluding an access point for use in wirelessly connecting to a network. The method includes collecting historical connection data for a first access point, wherein the historical connection data identifies a plurality of previous wireless connections to the network using the first access point and identifies a corresponding duration of each previous wireless connection. The method further includes: detecting that the first access point is available for a current wireless connection to the network; calculating an expected connection duration for the first access point using the historical connection data; and determining whether to select or exclude the first access point as a candidate for the current wireless connection based on the expected connection duration calculated for the first access point.

A base station () of a cellular communication system () comprises an RNC interface () which receives a radio link handover initiation message for a radio link from a radio network controller (). A switch delay processor () determines a handover switch delay and a characteristics processor () sets a characteristic of a radio link handover acknowledge message in response to the handover switch delay. A message generator () generates a radio link handover acknowledge message and transmits this to the radio network controller (). The radio network controller () comprises an RNC handover controller () which determines a radio link handover switch time in response to the characteristic. A better timing of the radio link handover may be achieved. The invention may e.g. be applicable to an HSDPA (High Speed Downlink Packet Access) service of a UMTS (Universal Mobile Telecommunication System) cellular communication system and may reduce the amount of data discarded from buffers during an HSDPA handover.

A method and apparatus for transmitting data in a radio communication system includes a data segmenter () segmenting data into data segments that are fed to a transmission encoder () which encodes them into transmission blocks having different energy per information bit levels. The transmission blocks are transmitter and feedback information is received from the remote radio station (). An analysis processor () determines an analysis group that comprises at least two data segments having transmission blocks encoded with different energy per information bit levels. The analysis processor () further generates a performance distribution measure relating to the analysis group in response to the feedback information. A transmission controller () selects a transmission scheme to apply to subsequent data segments in response to the performance distribution measure.

An apparatus and method of generating downlink power information for a multi-sector base transceiver site in which power can be shared between existing amplifiers includes a first step of gathering (S) downlink power information for each sector. When the total power required by the sectors is less than the total power available from the base transceiver site, a next step includes modifying (S) the information to pre-empt traffic loading such that a more heavily loaded sector will be disproportionately allocated more power than a less heavily loaded sector. A next step includes forwarding (S, S) the information to controllers of the base transceiver site. A next step includes determining a loading of each sector using thresholds to determine an overload in sectors depending on the information, wherein the power to each sector is adjusted disproportional to the degree with which the sector is loaded.
