Abstract
The invention relates to a method and device for simple and efficient determining characteristics during a transition between an AAL2 signalling protocol and at least one another signalling protocol of at least one communication network. The inventive method and device are characterised in that at least one characteristic is determined on the basis of parametric values assigned to the AA2 signalling protocol and in that the determined characteristics are used for reproducing the parametric values of the AA2 signalling protocol in the parametric values of another signalling protocol.
Claims18
A method for transitioning an AAL2 signaling protocol into at least one further signaling protocol of at least one communication network, comprising:
- in processing unit, determining at least one characteristic from the parameter values specified for the AAL2 signaling protocol;
- and
- in the processing unit, using the determined characteristics for mapping parameter values of the AAL2 signaling protocol into parameter values of the further signaling protocol, wherein a transition is performed to convert the Link Characteristics parameter values of the AAL2 signaling protocol to the Transfer Capabilities parameter values of the AAL2 signaling protocol;
- wherein a transition is performed to convert the Link Characteristics parameter values of the AAL2 signaling protocol to the IP Transfer Capability parameter values of a signaling protocol for IP connections;
- and
- wherein in order to determine the bit rate for the transition of the Link Characteristics parameter values of the AAL2 signaling protocol to the IP Transfer Capability parameter values of a signaling protocol for IP connections, a minimum header bit rate on the IP side is determined from a number of data packets per time unit of the peak rate at maximum packet size and the bit rate is determined in conjunction with the peak byte rate.
A device for transitioning an AAL2 signaling protocol into at least one further signaling protocol of at least one communication network, comprising:
- a receive unit for receiving parameter values of an AAL2 signaling protocol;
- a processing unit for determining at least one characteristic from parameter values specified for the AAL2 signaling protocol and for mapping parameter values of the AAL2 signaling protocol into Transfer Capability parameter values of the further signaling protocol;
- and
- a transmit unit for transmitting the mapped parameter values of the further signaling protocol, wherein a transition is performed to convert the Link Characteristics parameter values of the AAL2 signaling protocol to the Transfer Capabilities parameter values of the AAL2 signaling protocol;
- wherein a transition is performed to convert the Link Characteristics parameter values of the AAL2 signaling protocol to the IP Transfer Capability parameter values of a signaling protocol for IP connections;
- and
- wherein in order to determine the bit rate for the transition of the Link Characteristics parameter values of the AAL2 signaling protocol to the IP Transfer Capability parameter values of a signaling protocol for IP connections, a minimum header bit rate on the IP side is determined from a number of data packets per time unit of a peak rate at maximum packet size and the bit rate is determined in conjunction with the peak byte rate.
