Abstract
The present invention relates to a method for sharing dynamical loads signal-command points and subsystems, which solves the problems that when a signaling transfer point (STP) realizes the dynamical load sharing of signaling points or subsystems, only 16 links are used for transferring ordered messages to destination signaling points or subsystems, and the load equalization of each link can not be realized. When the present invention is used, all links from the STP to the destination signaling points or the subsystems can be fully utilized, and the equalization of message flow rates of the links is realized. An origin signaling point code (OPC) of each ordered message is divided into segments according to signaling sectioning point codes set in a data table, the message which is divided into segments is respectively transferred to two destination signaling points or subsystems to realize the load sharing, and the messages can be sent to destination signaling points or the subsystems according to the pairity of values of link option codes (SLS) of the messages; the messages can be sent to destination signaling points or the subsystems according to sizes of the SLS values of the messages; the messages can be sent to destination signaling points or the subsystems according to the segments of the OPCs without considering the SLSes.
Description
Technical field
The present invention relates to signaling system, be meant the signalling point in SCCP (SCCP) module of signaling system and the method for subsystem dynamic load share of command especially.
Background technology
In signaling system, particularly in the No.7 signalling system, Signaling Transfer Point is determined by the link selection code (SLS) of the message that sends to STP to the number of links of destination signaling point (SP).According to the international regulation of SCCP, SLS represents with 4 bits, so the scope of SLS value is 0～15, therefore, STP mostly is 16 most to the number of links of SP.When message traffic was big, 16 links had restricted bandwidth, do not satisfy the performance requirement of STP, number of links need be increased to satisfy the demands.
At present the existing pair of signalling point and realize that based on the method for the dynamic load share of command of the subsystem of two signalling points STP and SP can be direct connections in the SCCP module also can be non-direct connection.According to global title (Global Title, abbreviation GT) difference of translation result, what STP connected may be signalling point (being defined as DPC+GT or DPC+NEW GT), also may be subsystem (being defined as DPC+SSN), but two signalling points of SCCP are identical with method based on the dynamic load share of command of the subsystem of two signalling points, only describe with the method based on the dynamic load share of command of the subsystem of two signalling points of SCCP below therefore.
The message that SCCP handles is classified in order and is divided into unordered message and orderly message, and the unordered message of forwarding can be reselected SLS and send; And the message that the orderly message of transmitting requires to contain identical SLS is sent to SP according to the order that enters, so SLS that need this is identical sends successively from same link, at this moment the SLS in the message can not change.
Because unordered message and orderly message self, when realizing SCCP signalling point or subsystem load sharing, existing method can only realize the complete load sharing of unordered message, makes number of links be increased to 32, and realizes flow equalization; For orderly message, can only realize that sub-load shares, do not reach the purpose that increases number of links, can not realize flow equalization.
For unordered message, can realize the dynamic load share of command of subsystem by the method for polling.
Referring to Fig. 1, when STP 101 transmits unordered message to certain purpose subsystem, at first send to the main subsystem (DPC1+SSN) 102 of using, the value of SLS is 0; When arriving the forwards of this purpose subsystem for the 2nd, select standby subsystem (DPC2+SSN) 103, the value of SLS is 0; When arriving the forwards of this purpose subsystem for the 3rd, select DPC1+SSN 102, the value of SLS is 1; When arriving the forwards of this purpose subsystem for the 4th, select DPC2+SSN 103, the value of SLS is 1; ...; Like this until after the value of SLS arrives 15, more again by top method circulation, the message that obtains mailing to certain signalling point is shared at 32 link uniform loads.The value of above SLS is drawn by following two formulas.
SLS(DPC1)＝(SLS(DPCl)+1)％16
SLS(DPC2)＝(SLS(DPC2)+1)％16
These two formulas are surplusly come to the SLS of message assignment again by SLS (DPC1)+1 and SLS (DPC2)+1 are got.With the SLS assignment that at first sends to the message of DPC1+SSN and DPC2+SSN is 0, utilizes above two formulas to make the SLS assignment again that complementation will be mail to the message of active and standby subsystem then.
For orderly message, existing load sharing algorithm is as follows:
According to the parity of the SLS value of the orderly message that sends to STP select main with or standby subsystem carry out load sharing, forwards is gone out.With the value of SLS be 0,2,4 ..., 14 message send to main use subsystem, the value of SLS be 1,3,5 ..., 15 message is sent to standby subsystem, vice versa.
Load sharing algorithm for above orderly message, because SLS has only 16 values, corresponding can only corresponding 16 links, so can only use main two 8 links at most with signalling point under subsystem and the standby subsystem according to the parity assignments of SLS value, promptly can only corresponding 16 links, and can not all use STP to arrive main 32 links with signalling point under subsystem and the standby subsystem, do not reach the purpose that increases number of links, and the mass flow discrepancy of each link weighing apparatus.

Embodiment
The present invention is further illustrated below in conjunction with drawings and the specific embodiments.Because the dynamic load share of command of subsystem is based on signalling point, signalling point is identical with the method for the dynamic load share of command of subsystem, thus below only describe with the method for the dynamic load share of command of the subsystem of SCCP.
Referring to Fig. 2, the subsystem of making load sharing is based on two signalling points.In the subsystem tables of data, increase a configuration field, be signaling segmentation point coding opc_code, opc_code is set to half of OPC of orderly message to be transmitted, so that OPC can be divided into two sections by it, thereby orderly message to be transmitted also is divided into two sections.The OPC Origination Point Code that rises of OPC＜opc_code is set to OPC1201, and the OPC Origination Point Code that rises of OPC＞=opc_code is set to OPC2 202, and OPC1 201, OPC2 202 can obtain from the Route Selection mark (LABEL) of message.The message dynamic assignment of OPC1 201 is given main with subsystem (DPC1+SSN) 204 or standby subsystem (DPC2+SSN) 205, i.e. solid line pass-along message in the figure; And give DPC2+SSN 205 or DPC1+SSN 204 with the message dynamic assignment of OPC2 202, i.e. dotted line pass-along message in the figure, the two forms complementary relationship.
Above-described dynamic allocation message has three kinds of modes, respectively shown in Fig. 2,3,4.
Fig. 4 wherein be at message by the segment assignments message of OPC, and Fig. 2, Fig. 3 are by the situation assignment messages of its SLS value at message.Because the SLS value of message is equally distributed in the whole signaling net, so can be by selecting the active and standby uniform load that is implemented in 32 links with subsystem to share by the OPC segmentation in conjunction with the situation of its SLS value message.
Referring to Fig. 2, the orderly message that sends to STP 203 is made load sharing by the OPC segmentation and in conjunction with the parity selection of its SLS value is active and standby with subsystem according to it.When the playing an OPC Origination Point Code and be OPC1 201 of message, SLS value is sent to DPC1+SSN 204 for the message of odd number, the SLS value is that the message of even number sends to DPC2+SSN 205; When the playing an OPC Origination Point Code and be OPC2 202 of message, SLS value is sent to DPC2+SSN 205 for the message of odd number, the SLS value is that the message of even number sends to DPC1+SSN 204.
The message that also can be even number with SLS value in the message of OPC1 201 sends to DPC1+SSN204, and the SLS value sends to DPC2+SSN 205 for the message of odd number; SLS value in the message of OPC2 202 is sent to DPC2+SSN 205 for the message of even number, and SLS value is that the message of odd number sends to DPC1+SSN 204.
Referring to Fig. 3, the orderly message that sends to STP 203 is made load sharing by the OPC segmentation and in conjunction with the size selection of its SLS value is active and standby with subsystem according to it.When the playing an OPC Origination Point Code and be OPC1 201 of message, be little value with SLS value, promptly the SLS value is that 0～7 message sends to DPC1+SSN204, and the SLS value is a value greatly, and promptly the SLS value is that 8～15 message sends to DPC2+SSN 205; When the playing an OPC Origination Point Code and be OPC2 202 of message, SLS value is sent to DPC2+SSN 205 for the message of little value, SLS value is that the message of value greatly sends to DPC1+SSN 204.
The message that also can be big value with SLS value in the message of OPC1 201 sends to DPC1+SSN204, and the SLS value sends to DPC2+SSN 205 for the message of little value; SLS value in the message of OPC2 202 is sent to DPC2+SSN 205 for the message of big value, and the SLS value is that the message of little value sends to DPC1+SSN 204.
Referring to Fig. 4, by the segmentation of the OPC of the orderly message that sends to STP 203, be that the message of OPC1 201 all sends to DPC1+SSN 204 with playing OPC Origination Point Code, be that the message of OPC2 202 all sends to DPC2+SSN 205 with playing OPC Origination Point Code.
Can be that the message of OPC2 202 all sends to DPC1+SSN204 with playing OPC Origination Point Code also, be that the message of OPC1 201 all sends to DPC2+SSN 205 with playing OPC Origination Point Code.
The above three kinds of methods of utilization all can just use up 32 links so that the message of OPC1 and OPC2 active and standbyly forms complementation during with subsystem mailing to, and the load balancing of each link.
If main is in same entity with subsystem DPC1+SSN and standby subsystem DPC2+SSN, the SP support multiple signaling points feature that promptly is connected with STP uses the present invention STP can be increased to 32 to 16 links of SP so.
The method of above subsystem dynamic load share of command is based on the dynamic load share of command of two signalling points.Data configuration by antithetical phrase system data table is the OPC segmentation, and in conjunction with message in order by the situation of its SLS value grouping, can realize that also orderly message reaches dynamic load share of command based on the subsystem of multiple signaling points at multiple signaling points.With the dynamic load share of command based on the subsystem of three signalling points is example, and its concrete configuration is as follows:
Referring to Fig. 5, be dynamic load share of command based on the subsystem of three signalling points.These three groups of subsystems become two purpose subsystems, and one of them subsystem is the public standby subsystems of these two purpose subsystems, need two different GT configurations be set to these two purpose subsystems.In this dynamic load share of command, can only send to primary and backup subsystem to message in mode with the OPC segmentation based on the subsystem of three signalling points.Main standby subsystem with subsystem DPC1+SSN 504 and DPC3+SSN 506 is DPC2+SSN 505, be that DPC2+SSN 505 is public standby subsystem, therefore, the message of transmitting is carried out not equal segments, and the message after the segmentation mail to corresponding master respectively with subsystem or standby subsystem, so that mail to the message and the message equivalent that mails to DPC1+SSN 504 and DPC3+SSN 506 of DPC2+SSN 505.Can be set to 1/3 of OPC by opc_code, the OPC Origination Point Code that rises of OPC＜opc_code is set to OPC1 501, and the OPC Origination Point Code that rises of OPC＞=opc_code is set to OPC2 502.Select active and standby with subsystem DPC1+SSN504 and DPC2+SSN 505 or DPC3+SSN 506 and DPC2+SSN 505 according to message, the message of OPC1 501 is all sent to public standby subsystem DPC2+SSN 505, the message of OPC2 502 is all sent to main with subsystem DPC1+SSN 504 or DPC3+SSN 506.
The signalling point in the SCCP module of the present invention and the method for subsystem dynamic load share of command, be used in the STP system, through experiment and simulation, STP shares to the uniform load of the message traffic of 32 links of pair signalling points or subsystem in the time of can realizing that two signalling points or subsystem are made dynamic load sharing, has strengthened the performance of STP effectively.
By to the data configuration of tables of data with the OPC segmentation, and select active and standby with signalling point or active and standby use subsystem in conjunction with its situation of pressing the grouping of SLS value the message after the segmentation, can also realize the dynamic load share of command of multiple signaling points and subsystem, can make full use of STP all links, and reach the message traffic equilibrium of each link to signalling point or subsystem.
