The invention relates to a method to provide an operator selection service for subscribers of a communications network (CN′), wherein the subscribers terminals (T1, T2, . . . , Tn) are connected to one local exchange (ILEX) of a first operator, wherein said local exchange (ILEX) detects, whether call handling of an incoming call request is to be performed within network devices of said first operator or to be passed to a second operator, wherein, if a call is to be passed to the second operator, the local exchange (ILEX) identifies the calling address and the called address and sends a call information (M1) comprising said addresses to a call server (LS1, LS2) of the second operator, the call server (LS1, LS2) sends back a connection request (M2) to establish a call connection between selected terminals (T1, T2, . . . , Tn) over a determined fixed connection (TC1, TC2) connecting an outgoing trunk (X1, Y1) and an incoming trunk (X2, Y2) of said local exchange (ILEX) and the local exchange (ILEX) establishes the requested call connection over said determined connection (TC1, TC2), and also to a communications network (CN′) and a call server (LS1, LS2) therefore.
A communications network for a provision of an operator selection service for subscribers of a communications network, comprising a local exchange having connections to subscriber terminals and a signalling network for transmitting signalling information between communications network devices, wherein a predefined number of pairs of ports of said local exchange are each interconnected by a connection loop and a call server is connected to said signalling network, wherein said local exchange is adapted to send a call information message comprising the addresses or identities of both the calling subscriber and called subscriber to said call server, wherein said call server is adapted to receive said call information message and to send a connection request for advising an establishment of a connection over a defined communication channel of an assigned connection loop between terminals determined in said connection request message to said local exchange.
A call server for a provision of an operator selection for subscribers of a communications network, with an interface to a signalling network of said communications network, wherein said call server is adapted to receive on said interface a call information message comprising the addresses or identities of both the calling and called subscriber and to send a connection request message on said interface for advising a local exchange to establish a connection between terminals over a defined communication channel of an assigned connection loop determined in said connection request message.
