摘要:
Rerouting, as specified by ITU-T Q.730 is a network service that is executed by and under control of switching nodes, whereas IN services are executed under the control of a service control entity and invoked for certain calls only. Because of the two levels of control that are also separate from each other, inconsistencies may occur when an IN service is invoked for a call that may be in addition subject to rerouting. This problem is solved-in that a service control entity is adapted to perform the steps of receiving information relating to the rerouting of the call from the service switching entity, selecting a rerouting procedure for the call according to the received information, and sending an instruction to the service switching entity to continue the call according to the rerouting procedure. The information relating to the rerouting of the call information is in particular information about a rerouting capability of a preceding switching node.

Methods and devices for controlling a set-up of a call from a calling entity (CE201) to a called entity in a telecommunications network are described. The telecommunications network comprises a service control entity (SCE205) and a service switching entity (SSE204). The service control entity (SCE205) is adapted to perform the steps of receiving from the service switching entity (SSE204) an indication that the first call attempt failed, receiving from the service switching entity (SSE204) 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 (SSE204) to continue the set-up of the further call attempt according to the call establishment procedure.

Methods and devices for controlling a call in a telecommunications network are described. The telecommunications network comprises a service control entity (SCP204), a service switching entity (SSSF203) and a switching node (MSC205). The call is subject to a first service invoked for a first call party (CP201) and provided by the service control entity (SCP204), and to a second service invoked for a second call party (CP207) and provided by the switching node (MSC205). The service control entity (SCP204) performs the steps of receiving (239) a message comprising an indication of an invocation of the second service from the service switching entity (SSF203), selecting a procedure for handling the invocation of the second service based on a knowledge about the second service and a knowledge about the first service, and sending (240) an instruction to the service switching entity (SSF203) according to the procedure for handling the invocation of the second service.

摘要:
The invention relates to a method for controlling an explicit call transfer during a call in a telecommunications network comprising a switching node and an intelligent network, the intelligent network comprising a service control entity and a service switching entity. The service switching entity detects that explicit call transfer is invoked, and then sends a report to the service control entity indicating that explicit call transfer took place for the call. The report may comprise the call transfer number and a call transfer phase indicator indicating whether the call is active or in alerting state. The service control entity receives the report and will control the call transfer depending on the report.

Means and methodology for a telecommunication network are provided that allow using an IMEI of mobile terminal as destination or identification instead of the regular IMSI or MSISDN. This capability of the telecommunication network is provided by maintaining a set of coupled pairs of IMEI and IMSI/MSISDN. Operational messages in the telecommunication network having an IMEI address as destination or identification are translated by the appropriate IMSI or MSISDN depending on the message type, from a coupled pair having the same IMEI. Means is provided with a STP capable of maintaining the set of coupled pairs. Further several implementations are provided using the IMEI addressing capability.
摘要:
A method of routing a call setup request to a destination serving node serving a destination subscriber in an IMS network. The method comprises the steps of a switching node receiving the call setup request having a destination number of the destination subscriber, the switching node querying a number conversion database node for destination routing information using the destination number. The method further comprises the steps of the number conversion database node querying subscriber information for destination serving node information related to the destination number, the number conversion database node receiving destination serving node information from the subscriber information, the number conversion database node replying to the switching node with destination routing information comprising the destination serving node information and the switching node routing the call set up request to the destination serving node using the destination serving node information.

A method of and an arrangement for call establishment between user equipment (1) operating as a dient in an internet communication environment (4), and user equipment (2, 3) operating as a dient in a mobile communication environment (5). The mobile communication user equipment (2, 3) is emulated as a dient in the internet communication environment (4). A Status of the mobile communication user equipment (2, 3) is represented in the internet communication environment (4). Calls are established with the mobile communication user equipment (2, 3) operating as a dient in the internet communication environment (4).

The invention relates to an application server in a telecommunications network for transferring a communication session from a first connection between a first client and a remote client to a second connection between a second client and the remote client. The communication session comprises a media path and a signalling path. The application server being arranged to a) receive a transfer request, b) send a set-up request to the second client, for setting up the second connection, c1) transfer the signalling path, c2) transfer the media path, d) send an update message towards the remote party, the update message comprising an indication that the transfer has been executed, and e) send a termination message to the first client to terminate the first connection.
