A system has a first entity and a second entity. The first entity and second entity are arranged to have a control interface therebetween. At least one of said first and second entities is arranged to associate a resource with at least one connection. At least one of said first and second entities has means for checking the status of the connection and to release an associated resource if the connection is terminated.

System and method for controlling an associated network connection with a mechanism of terminating the same

A method and system including at least one media gateway and at least one media gateway controller controlling the media gateway. The media gateway uses structured termination identities for identifying terminations on the media gateway that source and/or sink media and/or control streams. In order to assure a correct specifying of one or more terminations of the media gateway, the media gateway controller contains, or has access to, structure information of the structure of the termination identities. The structure information describes the bit sequence and/or the information represented by the bits or bit sections of the termination identities. Therefore, wildcarding commands can be properly defined.

Method for registering an overload situation in a telephone exchange system comprising a local exchange, an access node, a concentrating interface connecting the access node to the local exchange, a resource manager, which is part of the local exchange and a statistical unit, which is part of the local exchange. The method comprises the steps of scanning the concentrating interface to find a free time slot and detecting by means of the resource manager that the concentrating interface is overloaded. The method further comprises the steps of sending to the statistical unit a message reporting congestion, based on information existing in the resource manager, and recording the congestion situation into a traffic measurement report by means of the statistical unit.

Method and system for the management of a V5 interface in a telecommunication system comprising a first network element, a second network element, which is connected via a V5 interface to the first network element, and a management interface connected to different network elements. Link identification is performed on the basis of a standard request issued from a network element. According to the invention, when link identification is requested via the management interface and when link identification cannot be started in the network element through whose management interface the link identification request is issued, a notice of failure of link identification is given locally to the management interface.

Method and system for the management of an interface in a telecommunication system

Procedure for releasing the connection between a user port and an associated channel, or voice time slot, in an access node (AN) connected to a local exchange (LE) via a V5.2 interface. According to the invention, in a situation where there is a break in the V5.2 interface signalling channels, the connection between a user port and the associated channel may be left unreleased. In this case, the unsuccessful release of the connection between the subscriber port and the associated channel is stored in memory and the operation for releasing the connection between the subscriber port and the associated channel is carried out again.

Procedure for releasing connections

Procedure for accomplishing PSTN-mapping in a telecommunication system comprising a telephone exchange (LE) with a number of subscribers defined in it, a first access node (AN,), which is connected to the telephone exchange via a first V5 interface (V5), a second access node (AN,), which is connected to the first access node (AN,) via a second V5 interface (V5&prime;), and terminal equipment (TE) connected to the second access node (AN,), the connection between the subscriber and the telephone exchange (LE) being set up by cascading the two V5 interfaces. The signalling sequences and message decoding in PSTN-mapping are exclusively taken care of by the telephone exchange (LE) and the second access node (AN,), and the signalling is transmitted transparently through the first access node (AN,) without the first access node participating in the decoding of the signalling.

Procedure for providing a pstm-mapping in a telecommunication system

Procedure for subscriber addressing in a cascaded V,interface in a data communication system comprising a telephone exchange (LE) with a number of subscribers defined in it, and access network (AN) connected to the telephone exchange via a first V,interface (V,) and comprising a first access node (AN,), a second access node (AN,), which is connected to the telephone exchange, and a subscriber terminal (TE), which is connected to the local exchange via the access network and/or the second access node. According to the invention, the second access node (AN,) is connected to the first access node (AN&excl;) via a second V,interface, the connection between the subscriber and the telephone exchange (LE) being set up by cascading the two V,interfaces, subscriber parameters comprising an identifier of the first V,interface (V,) and an identifier of the second V,interface (V,&prime;) and the subscriber's L,address consistent with the V,definitions are defined for each subscriber, the signalling between the subscriber and the telephone exchange being effected using the first and second V,interfaces in accordance with the identifiers.
