Fig. 1 utilizes GT interpretation method provided by the invention, realizes that between a plurality of signalling points the derivation GT of an embodiment of load sharing translates the flow chart of out office direction.

Embodiment

The inventive method is proposing completely new concept aspect the selection of the tissue of GT translation data and signalling point.On the one hand, propose the GT translation realizes load sharing between a plurality of signalling points method, adopt following steps: each signalling point method representation of setting that 1) GT need be translated; 2) by specific method configuration GT data, the ratio of sharing of the signalling point that assumed load is shared and each signalling point; 3) carry out the GT translation according to the method for setting, select the signalling point of GT translation.On the other hand, propose the notion of GT translation chooser, be about to comprise that combinations of attributes such as GT deictic word, Translation Type, code scheme, nature of address indicator are defined as GT translation chooser.On this basis, during the GT translation, at first carry out the coupling of GT translation chooser, then select different GT translation results with the GT number by specific GT translation chooser.

Illustrate the mode of an enforcement of the inventive method below.

1. the expression of different signalling points:

Represent variant signalling point with the notion of adjacency office direction, signalling point is a particular attribute in abutting connection with office direction.Because SLC (Signaling Link Code, Signal Link Code) span is for being 0～15, when the signaling link that connects a SPC during greater than 16, this signalling point corresponding physical office direction can be configured to a plurality of logics in abutting connection with office direction, guarantee that the signaling link way in abutting connection with office direction that connects each logic is no more than 16, by the configuration of adjacency office direction, the GT translation also promptly realizes load sharing a plurality of in abutting connection with between office direction at the load sharing between the multiple signaling points.

2.GT translation chooser configuration

The attribute except the GT number used in the GT translation process such as GT deictic word, Translation Type, code scheme, nature of address indicator etc. are represented with the combination of GT translation chooser.

When the GT number is the same, and above-mentioned attribute is different, when requiring the result of GT translation also different, can select different GT translation results by different GT translation choosers with the GT number by the different GT translation chooser of configuration.

When the GT number is the same, and certain property value requires the result of GT translation the same when getting different value, also promptly needs to shield certain particular community, then can dispose identical GT translation chooser.Determine the same result by identical GT translation chooser with the GT number.

3.GT the configuration of number translation data

Step 3: calculate GT translation office direction, GT translation multiple signaling points load sharing selects this to translate the principle of out office direction:

Preserve following multidate information in the GT translation data: current take turns choose selected number of times in abutting connection with office direction and this office direction;

Current when having selected the selection number of times that number of times reached the polling office direction, the polling office direction is pointed to next office direction;

During the new office direction of each polling, selected the number of times counter O reset;

Judge whether the office direction (signalling point) that wheel is chosen can reach, and translate successfully in order to guarantee GT, when the office direction of choosing when wheel is unreachable, direct polling next one office direction;

When GT translation multiple signaling points load sharing is selected the success of polling office direction, select time counter to add one, and preserved the multidate information (mainly being to preserve current polling office direction and selected time counter) after the GT translation.

Step 4: the office direction that is calculated by step 3 obtains corresponding signaling point.
