Methods and devices for controlling a set-up of a call from a calling entity (CE) to a called entity in a telecommunications network are described. The telecommunications network comprises a service control entity (SCE) and a service switching entity (SSE). The service control entity (SCE) is adapted to perform the steps of receiving from the service switching entity (SSE) an indication that the first call attempt failed, receiving from the service switching entity (SSE) an indication of the further call attempt, obtaining call information related to the first call attempt, determining a call establishment procedure for the further call attempt based on the call information related to the first call attempt, sending an instruction to the service switching entity (SSE) to continue the set-up of the further call attempt according to the call establishment procedure.

Controlling a call completion

The invention relates to a method for controlling a multi party call between three or more communication entities within a communications network. The communications network comprise a service control entity and a service switching entity. The service control entity performs: a) receiving a notification of a multi party event associated with the multi party call from the service switching entity, b) determining a procedure for handling the multi party event, c) transmitting instructions to the service switching entity in accordance with the procedure for handling the multi parry event.

Method for controlling a multi party call and a service control entity and a service switching entity for performing the method

Methods and devices for set-up of a call in an intelligent network () comprising a switching entity (SE-,SE,SSF) and a control entity (CE-,CE,SCP) are described. The call is subjected to a control by the control entity (CE-,CE,SCP) and the control entity (CE-,CE,SCP) is adapted to perform the steps of obtaining (S) information indicating a status of a bearer for the call, determining (S) a bearer establishment procedure for the call by analyzing the obtained information indicating the status of the bearer and at least one requirement related to the call, and sending (S) an instruction to the switching entity (SE-,SE,SSF) to initiate an establishment of the bearer for the call according to the determined bearer establishment procedure.
