Management of performance of intelligent network services

A method for enhancing an intelligent network service and an intelligent network including service switching points and at least one service control point, the intelligent network being adapted to initiate an intelligent network service when detecting at a service switching point a detection point defined by a call state model and triggering a service, and the intelligent network being further adapted to set at the service switching point, as a response to the initiation of an intelligent network service at one of the detection points, one or more detection points to trigger or not to trigger one or more intelligent network services.

Enhancing an intelligent network service

A method and intelligent network service switching point for transferring the execution of IN service related functionality from the originating half-call to the terminating half-call. For the functionality to be transferred, the service of a portion thereof is determined as a transferable service in the originating half-call. When the transferable service is encountered, information thereon is sent to the terminating half-call in which the is triggered.

Call control in intelligent network

An intelligent network comprising service switching points ( ) and at least one service control point ( ), whereby for one or more call state models there are two or more service logic programs located at the service control point ( ), the intelligent network being arranged to direct the call state model to a certain detection point or call phase in response to an operation sent by the intelligent network service, wherein at the service switching point at least one operation is defined, for the execution of which the service switching point can select from two or more alternative routes or detection points to which the service switching point can direct the call state model whereby the service control function is arranged to indicate the route or detection point to which the service switching point is to direct the call state model in connection with said sending of an operation.

Controlling intelligent network services

A method associated with an intelligent network service, comprising the following steps for detecting a special situation and acting in the special situation in the best possible way: defining for the service at least one special situation which is failed for the service but successful for the switching point, defining an instruction for said at least one special situation, receiving at the detection point a message indicating the existence of the call-related service for which the special situation has been defined, receiving at the switching point a first routing instruction ( ) either from a caller or the control point, checking said first routing instruction ( ), detecting the special situation ( ) if the first routing instruction includes the special situation, and following said instruction in response to the detection of the special situation. Besides the method, the invention also relates to an intelligent network, a service control point and a switching point of an intelligent network.

Special situation in intelligent network during which service provisioning fails but switching point operates successfully

The invention concerns interworking between distributed services in a telecommunications network, especially in an intelligent network. The invention is based on the idea that at least one new Interworking Point is introduced to the call handling model and with the aid of this Interworking Point the interworking between the distributed services is implemented. The Interworking Point can be defined as either a point where instructions received from one service program are reported to interested service programs or as a point where a service to be carried out by the responsible service program is requested by some other service program. The interworking points are armed by the service programs, and the service programs which armed the interworking point are informed of the encounter with an interworking point.

Interworking between services in telecommunications network

When the user lifts the receiver, the terminal of a wireless local loop telephone system detects this and generates a dial tone as normally. The user starts dialing. But instead of waiting for completion of dialing, the terminal immediately sends a channel request message to the network. This triggers the exchange of normal messages with the result that a signaling channel is assigned, an authentication procedure is performed and the ciphering mode is set up during the time when the user is pressing keys to give a called subscriber's telephone number. Because dialing is still in process and the called subscriber's number is not yet available, the terminal puts a predetermined pseudonumber into a message which normally carries the called subscriber's number. The pseudonumber informs the network that the terminal will send the telephone number of the called subscriber later. The number will arrive as DTMF digits on the assigned signaling channel.

Method for accelerating call establishment in a radio communication system

Services controlling the same call state model are independent of each other and do not necessarily have any knowledge of each other. To make the facilities of these parallel controlling services interoperable, at least one parameter is defined, whose value indicates whether a controlling service may be initiated to control a control record, if a controlling service has already been initiated. When detecting ( ) a situation triggering the initiation of a second controlling service in the control record controlling call set-up, the initiation of the second controlling service is continued ( ), if the parameter allows the initiation of the controlling service.

Initiating a controlling service

An arrangement for transmitting data in a telecommunications system utilizing an intelligent network and comprising at least one intelligent network service control point for providing intelligent network services and at least one intelligent network service switching point for providing a connection between the telecommunications system and the intelligent network services. In order to transmit the configuration data of the switching point to the service control point, the switching point is arranged to generate and send a configuration message to the control point for indicating the value of at least one parameter which belongs to the configuration data, and the control point is arranged to receive the configuration message. The invention further relates to an intelligent network service control point and a switching point, which can be utilized in the arrangement of the invention. The invention further relates to a method which can be utilized in the arrangement of the invention.

Intelligent network switching point and control point

It is advantageous to distribute tasks of network services logically into separate service programs and also physically into several control points. A problem in task distribution is the single point of control, whereby only one service program at a time can control the call. The invention concerns a method of service distribution to several service programs (SLP). A control relationship is formed between the switching point (SSP, MSC) and the service program (SLP) providing it with instructions. The method according to the invention is characterized in that the controllability of the relationship is divided into controllability classes, of which at least one is allocated to the service program (SLP) controlling the switching point (SSP, MSC) so that each controllability class is allocated to only one service program at a time, and the call is controlled by the service within the limitations of the control authorization of each controllability class.
