Abstract:
A method for setting up connections from a terminal equipment (TE) of a packet-switched communication network to a mobile terminal (MS) of a circuit-switched mobile communication network, the connections being routed from the TE through one or more access servers to the MS, said method comprising the steps of:a) sending a connection setup message from the TE to a first access server; b) selecting a second access server from an access server identification means in a some location register (HLR) in the mobile communication network based on a location of the MS in the mobile communication network and/or call processing specific characteristics indicating a specific type of call processing of the call in the packet-switched network and/or the circuit-switched mobile communication network, wherein the access server identification means includes a table indicating an access server address with respect to each mobile switching center (MSC) in the mobile communication network, and wherein the first access server provides information about the MS to the HLR which, in turn, determines the MSC currently serving the MS on the basis of the MS information, and reads out an appropriate access server address from the table in We HLR dependent on the determined serving MSC; c) routing the connection setup message to the selected second access server; and d) setting up the connection from the TE to the MS through the selected second access server.
