Abstract: A method for establishing calls in a communications network comprising a fixed network section and a mobile network section is provided. In the fixed network section, all calls to mobile called party addresses subscribers are signaled to a fixed network node capable of querying a home location register of the mobile network section. At that node, the home location register is queried and a roaming number is provided. The roaming number is then used for directly establishing a call from a calling fixed network subscriber to the mobile called party.

Abstract: The invention relates to message handling in SS7 communications networks. An inventive network arrangement comprises at least two SS7 network elements having a common first and individual second signaling point codes. A third network element also has the common signaling point code. At least one SS7 link set is provided between the at least two SS7 network elements. SS7 link sets between the at least two SS7 network elements and the third network element terminate at the individual second point codes, whereas SS7 links between the at least two SS7 network elements and other SS7 network elements having signaling point codes different from the common signaling point code terminate at the common point code in each of the at least two SS7 network elements.

Abstract: The present invention relates to an improved method and network element for activating links in telecommunication networks. The invention relates particularly to the automatic activation of M2PA links in network arrangements, in which network elements with different link activation proving methods are used.

Abstract: Telephone number portability is provided by decoding a key of an original number dialed into a profile that indicates an operation to be performed on the number dialed. At least one profile that indicates a manner in which the original number dialed is to be affected by an operation to produce a ported telephone number corresponding to the original dialed number.

Abstract: Operators of transfer points in the signalling network number 7 wish, on the one hand, to protect themselves against unauthorized use; on the other hand, these operators want to require fees for the use of the STP. The present invention solves this demand in a simple way in that it unites MTP charging with incoming linkset/DPC (desination point code) screening such that the accounts and their respective sub-accounts could be managed according to the evaluations of the covered traffic.
