Abstract: The present invention relates to methods, a communication network node and a user equipment for detecting collision of physical cell identities in a communication network system comprising radio base stations each serving at least one cell through which user equipments are moving. Reference signals comprising reference symbols corresponding to a physical cell identity are sent from said radio base stations to said user equipments over a radio interface. Transmission gaps of reference symbols are inserted in the reference signal in order to perform a physical cell identity collision test. The user equipments are arranged to detect if any other radio base station is sending reference symbols corresponding to the same physical cell identity during the transmission gaps. Thereby a physical cell identity collision is detected.

Abstract: Methods and devices for charging a user for access to a service accessible via a communication network are disclosed. At least two charging-related states are defined for the communication network. A tariff proposal entity associated with the user determines one or more tariff proposals for charging the user for accessing the service and sends the one or more tariff proposals to a rating entity. The rating entity analyzes the one or more tariff proposals in relation to a current charging-related state of the at least two charging-related states, wherein it is determined if at least one of the one or more tariff proposals complies with at least one tariff setting associated with the current charging-related state. The rating entity further selects a tariff of the at least one complying tariff proposals for charging the user for access to the service and initiates a charging of the user for access to the service according to the selected tariff.

Abstract: An armrest assembly is provided for adjusting an armrest of a seating unit in three degrees of motion. The armrest assembly includes an angle-adjustment mechanism that allows the armrest to pivot and to translate forward, and a lift mechanism that enables vertical articulation of the armrest. The angle-adjustment assembly includes a pivot bracket with a downwardly disposed pin and a shuttle with an arcuate slot to receive the pin. The arcuate slot includes contoured walls that form detents for restricting movement of the pin, thereby restraining rotation of the shuttle, with respect to the pivot bracket, to predefined angular positions. The lift mechanism includes a rack with ride element(s) extending therefrom and locking teeth, and a control bar with track(s). An upward manual actuation of the control bar causes the track to shift laterally and retract the locking teeth, via interaction between the track(s) and ride element(s), respectively.

Abstract: The present invention relates to a centralized power allocation method in a wireless telecommunication system comprising at least a first couple of terminals, consisting of a first transmitting terminal and a first receiving terminal, and a second couple of terminals, consisting of a second transmitting terminal and a second receiving terminal. A control node partitions the interference diagram between the communication of the first couple and the communication of the second couple, into different areas, each area being associated to a type of processing of the interference. The control node calculates the minimum power curve for each communication in each said area. The power values to be allocated are given by the coordinates of the point of intersection of both curves in said diagram.

Abstract: A method is provided for determining a correlation between a reference user and another user on the basis of two sets of ratings, where each rating is associated with a respective user. In response to a trigger, user ratings associated with the reference user and user ratings associated with the other user are collected, and all co-rated items of these two sets are correlated in the basis of an adjusted cosine correlation function which is weighted by a first and a second weighting function. The correlation is then stored and may be repeated for a plurality of users. The stored correlations may be used e.g. for ranking purposes.

Abstract: The invention relates to a method for controlling a bit-rate of a session in a packet-switched communications system where multiple sessions are set-up via a shared resource. A current bit-rate of the session is compared to a bit-rate range valid for the session to determine a distance from the position of the current bit-rate to one of the end-points of the bit-rate range. The current bit-rate is then adapted differently depending on the distance to the selected end-point. By controlling the bit-rate of each session that is set-up via the shared resource for applications that provide delay-sensitive services to users in this way the method and corresponding system and sender-receiver arrangements have the effect that rate adaptations can be distributed among the applications so that users share responsibility for rate adaptations.

Abstract: Logical content is defined by start/end times into a VoD media offering. The calculation of byte-range markers corresponding to the start/end times is distributed among the STBs to first request the particular logical content. Upon receiving an initial request for a logical content offering, an IPTV AS returns a VoD media file URL, start/end times, and null values of byte-range markers corresponding to the start/end times. In response to the null values, the initially-requesting STB downloads the entire VoD media file from a Download Media Server, and calculates the byte-range markers by comparing the start/end times to timestamps in non-encrypted headers in the VoD media file. The non-null byte-range markers are transmitted back to the IPTV AS, which provides them to STBs subsequently requesting the same logical content. The subsequently-requesting STBs may download only the logical content by providing the non-null byte-range markers to the Download Media Server.
