Abstract: It is disclosed methods, apparatuses, system and related computer program for handover procedures. The method comprises a network node verifying if a location area of a handover destination belongs to a zone wherein a subscriber is allowed to access services and based on such verification either successfully handing over a call or rejecting a handover request.

Abstract: It is provided an apparatus, comprising checking means adapted to check, upon receipt of a detection point of a service for a subscriber, if a pre-paging support is related to the service; interrogating means adapted to interrogate a location of the subscriber, wherein the interrogation comprises an indication of the pre-paging support if the result of the checking by the checking means is affirmative.

Abstract: This invention relates to a method for use in a communications system comprising the steps of determining if user equipment is capable of supporting a first technology and obtaining from said user equipment information about said user equipment only if said user equipment is capable of supporting said first technology.

Abstract: The present invention provides a mobile network for handling multiple subscribers having the same calling line identity. Each multiple subscriber has an individual mobile subscriber number and a common mobile subscriber number that can be used to replace the individual mobile subscriber number. One mobile subscriber has an identical individual and common mobile subscriber number, and the mobile network receives a mobile subscriber number from a multiple subscriber. The mobile network has a terminal management server that determines whether the mobile subscriber number is either the individual mobile subscriber number or the common mobile subscriber number. Each individual mobile subscriber number and common mobile subscriber number is a Mobile Subscriber Integrated Services Digital Network (MSISDN) number. The mobile subscriber number is used during a location update procedure.

Abstract: A dynamic synchronous transfer mode network includes first and second unidirectional buses 2 and 4, and a plurality of nodes, 0 to N−1. Each node includes a mechanism for selecting a bus. When a first node wishes to initiate a call with a second node, the selected bus is used to communicate with the second node. Each node includes a processor for calculating, for the selected bus, a ratio based on the number of previous reservations made by the node and the number of previous reservations relating to calls to or from the node. If the ratio is below a threshold, then a channel reservation device reserves one or more channels for a call. If the ratio is above the threshold, then the device requests a second node to reserve one or more channels for the call. This overcomes unfair operation of the network caused by the dual-bus topology.

Abstract: The invention relates to a signal processing method and apparatus for nuclear spectrometers, whereby the peaking time is set, which is optimal from the point of view of the signal-to-noise ratio, where in case of an input signal of staircase shape modulated with noise, the so called base-line filtering interval preceeding the actual signal and the signal filtering interval following the actual signal are chosen so that their widths are equal to the width of the optimal peaking time (T.sub.p), the momentary value measured in the base-line filtering interval (A.sub.i) is subtracted from the momentary value measured in the signal filtering interval (J.sub.i), where said momentary values (A.sub.i and J.sub.i) are measured in the time scale symmetrically with regard to the rising edge of the signal, and the differences (J.sub.i -A.sub.i) are summed with weighting factors (W.sub.i).
