Embodiment
In one embodiment of the invention, the network equipment is a distributed multi-master machine system configuration.The network equipment is provided with a plurality of Signaling Processing Units and connects with a plurality of SCTP that are implemented between the network equipment, each Signaling Processing Unit is the separate host system, and described Signaling Processing Unit can be gateway (SG), Service Control Point, call server equipment such as (call server).
As shown in Figure 2, signaling message transmission is based on Stream Control Transmission Protocol between the network equipment, and increases a signaling transfer management sublayer on Stream Control Transmission Protocol, in order to the management that realizes bottom SCTP signaling is connected.Being the high-level signaling message that will transmit on the STM, can be IETF signaling transmission SCN signaling adaptation layer that group formulated such as M3UA etc., also can be to support the signaling transmission conversion layer (STC) of BICC or H.248 wait agreement.The STM protocol function also can be realized in signaling adaptation layer or STC, can avoid being provided with separately the management function that one deck STM finishes many SCTP signaling links like this, reduces the protocol hierarchy interface.STM and upper-layer protocol function are to be realized by other host computer systems beyond the Signaling Processing Unit.
The main SCTP signalling connection managing function of STM layer comprises: 1, according to the Redundancy concept between the SCTP connection of definition, after a certain SCTP connects interruption, the business in this connection is switched to backup connect.Can define many backups for a certain SCTP connection and connect, every backup connection defines a backup priority, selects backup link according to the backup priority orders during switching.2, according to the load sharing principle of definition, the business between a pair of signaling entity on connecting, many SCTP signalings is carried out load sharing.Can prolong the method for carrying out load sharing according to the SLS territory of using for the No.7 signaling, can share according to the information in high-rise certain territory of signaling message for other signaling.
STM supports the sublayer many SCTP between a pair of signaling entity to connect, and only have SCTP to connect to be a special case in the STM function between a pair of signaling entity, so the network equipment increases and does not hinder after the STM sublayer and do not have the network equipment of STM sublayer function to carry out the intercommunication of agreement.
Therefore, in an embodiment of the present invention, signal transmission method may further comprise the steps:
(1) described STM sends out control command according to the configuration information on the network equipment, and the SCTP that sets up between the network equipment more than connects;
(2) described STM shares indication information and will transmit sharing of load and transmit to connecting more than one SCTP according to what the load sharing information in the signaling message that is transmitted or upper-layer protocol provided;
(3) described STM monitors the state that each SCTP connects, and is connected with fault if find certain bar SCTP, and then the business of out of order SCTP connection being born according to the configuration information on the network equipment switches in its backup SCTP connection and transmits.
According to signal transmission method of the present invention, between these paths, carry out load sharing existing many signaling paths and signaling message between two signaling end points, easy like this causing needs the high-level signaling message of order-preserving transmission out-of-sequence situation to occur, cause high-level signaling can't utilize this transmission mechanism, but signaling protocol generally is the agreement of session-oriented fortunately, out-of-sequence situation does not appear as long as guarantee the signaling message of same session, by selecting suitable load sharing principle can guarantee that the control signaling of same session all transmits from the same paths between two signaling end points, the signaling message that guarantees same session out-of-sequence situation can not occur, can guarantee that the signaling message that belongs to a CIC can transmit from same signaling transmission path when the arrowband isup message is carried out load sharing according to the CIC value, guarantee the order-preserving transmission of signaling message.
Fig. 3 has provided and has co-existed in the schematic diagram that four SCTP connect and how these connections distribute between a pair of network equipment.Independently Signaling Processing Unit treatment S CTP signaling connection is set on the network equipment, many signalings connections are distributed on a plurality of independently Signaling Processing Units, concentrate by the STM layer these SCTP signalings connections are managed.Each Signaling Processing Unit on same network equipment is separate, is connected with No. 2 SCTP as only influence No. 1 after Signaling Processing Unit 1 fault, and being connected with No. 4 SCTP for No. 3 can be not influenced.The IP address of supposing the Signaling Processing Unit 1 of the network equipment 1 is that the IP address of IP1, Signaling Processing Unit 2 is IP2, and the external IP address of the same network equipment 2 is IP3, IP4.The STM floor is sent out control command according to the data of configuration and is required it and IP3 and IP4 to set up No. 1 for Signaling Processing Unit 1 to be connected with No. 2 SCTP on the network equipment 1, also sets up No. 3 with IP3 and IP4 with the same manner requirement Signaling Processing Unit 2 and is connected with No. 4 SCTP.Co-existing in No. 1 to No. 4 SCTP at STM signaling transfer management floor to the network equipment 2 like this connects.
Load sharing between the STM management level can connect according to many SCTP of definition carries out the management that many SCTP signalings are connected with Redundancy concept, load sharing can define according to the principles such as distribution that are connected with the principle of backup, provide an example below: the signaling traffic flow that is defined into the network equipment 2 in the network equipment 1 side carries out load sharing equably in 1 to No. 4 SCTP signaling connection, and the backup connection of No. 1 SCTP connection is respectively No. 2, No. 3, No. 4 SCTP from high to low according to backup priority and connects.Suppose that the high-rise signaling of being transmitted is an arrowband No.7 signaling, low two of the SLS during load sharing in the use signaling message are carried out load sharing.When STM sends data according to the SLS value of transmission signaling message, selecting No. 1 SCTP to connect when SLS=XX00 sends, in like manner SLS=XX01 selects No. 2, SLS=XX10 selects No. 3, SLS=XX11 selects No. 4, can be evenly distributed on the upper-layer protocol data that will transmit in 4 SCTP connections by this load sharing mode.
The switch function that the STM layer connects many SCTP is to connect because certain reason becomes can not use the time as the SCTP of a certain operate as normal, and STM selects an other SCTP to connect according to predefined connection backup priority to transmit the signaling traffic that unavailable SCTP connection is born.Detecting No. 1 SCTP as the STM floor connects after the fault, can preferentially select for use No. 2 SCTP to connect according to the backup connection priority of definition and replace No. 1 SCTP connection, bear the original business that No. 1 SCTP bore, also have fault to select for use other SCTP to connect according to the backup priority order of definition again if connect for No. 2.
