Description
Technical field
The present invention relates to network communications technology field, relate in particular to a kind of method that realizes signalling network interconnection.
Background technology
Usually, for a country or concrete telecom operators, their signaling network is to have clear and definite NI's (network identity), described NI is traditional SS7 (Signaling System 7(SS-7)) network identity that network standard limited, and this sign comprises: the domestic main net of using, national standby network, four kinds of international main usefulness net and international standby networks, be reflected in specifically on the signaling message that transmits on the signaling network, be exactly the NI that has only a byte among the SIO (business information eight hytes) in each MTP3 (message transfers part) message header, because NI only takies two bits, so can only be used for distinguishing four types signaling network.
Complicated along with communication network, part operator oneself needn't build signaling network but use the signaling network of other operator by mode such as renting, and this just makes a signaling network to provide service for a plurality of operators simultaneously as community network.In order to guarantee that a signaling network can be simultaneously be the service of a plurality of operators, and guarantee not influence each other again between each serviced operator, then need between network, adopt certain isolation technology.
Yet, because in a country, the NI of the signaling network that a plurality of operators use all is chosen as the domestic main net of using, so rely on NI that a signaling network can't be realized for a plurality of operators provide service manner simultaneously, but also because the qualification of corresponding standard, also can't expand, to satisfy the demand that it provides many network services at the NI that two bits are only arranged.
For these reasons, signaling network between each present operator is independent separately the construction, and, the signaling point code resource of each operator also is that oneself independently distributes, cause existing probably between a plurality of operators the signaling point code that repeats, thereby make the signaling interworking between network can't realize, especially at the MTP3 layer at all.
At present, each signaling network is respectively independent separately and builds, and only realizes signalling interworking at the client layer of MTP3.Promptly signaling message is not directly to transmit at the MTP3 layer between network when the call proceeding of across a network, but signaling message initiates a call to another network then again through the client layer protocol processes of MTP3 on the gateway device between the network.And internetwork signaling network remains isolation, and the intercommunication of this client layer may cause unnecessary communication session circuitous.
For this reason, the network operation demand wishes to realize that a plurality of operators can a shared signaling network, promptly must realize the intercommunication of MTP3 layer, still, also do not have at present corresponding techniques to realize the intercommunication of MTP3 level, just can't realize that a signaling network is respectively a plurality of operators service is provided yet.
For example, as shown in Figure 1, in the scope of SS7 consensus standard, a plurality of carrier networks all use same NI, and use the signaling point code that may repeat, at this moment, the STP equipment that each carrier network can't shared same signaling network, especially use under the situation of different consensus standards, for example in Fig. 1 at different carrier networks:
Network 1:NI is " the domestic main net of using "; Use the SS7 agreement of ANSI (American National Standards Institute) standard; Use 14 bit signaling point coded systems;
Network 2:NI is " the domestic main net of using "; Use the SS7 agreement of ansi standard; Use 24 bit signaling point coded systems;
Network 3:NI is " the domestic main net of using "; Use the SS7 agreement of ITU-T (International Telecommunications Union) standard; Use 14 bit signaling point coded systems;
Network 4:NI is " the domestic main net of using "; Use the SS7 agreement of ITU-T standard; Use 24 bit signaling point coded systems.
In Fig. 1, STP equipment can't provide service simultaneously for above-mentioned four networks.Yet, along with the construction of communication network, the application demand of above-mentioned networking has appearred.This just makes realizes that above-mentioned each internetwork intercommunication becomes a problem demanding prompt solution.

The STP equipment that the present invention need realize using the shared same signaling network of a plurality of communication networks of the same country of same NI or an operator is finished the transmission of signaling, promptly on STP equipment, realize the logical network function, thereby STP logically has been divided into a plurality of equipment, and each logic STP equipment provides service for a concrete carrier network.As shown in Figure 2, being divided into the STP equipment of a plurality of logic STP equipment can be simultaneously provide signaling to transmit service for the network of a plurality of operators, promptly the logical network based on each logic STP equipment can provide the signaling service for a carrier network, in STP equipment, can also realize signalling network interconnection according to the intercommunication setting between the logical network of reality.
Describe below in conjunction with the specific implementation of accompanying drawing method of the present invention.
The specific implementation process of method of the present invention comprises as shown in Figure 3:
Step 31: in signalling processing equipments such as STP/SG, be divided into some groups, every group of corresponding logical network with the signaling link group resource data in the equipment and with the signal resources such as destination signaling point resource data of this spot correlation; Promptly in signaling network equipment, set up corresponding logical network, be each logical network configuration signaling link group and destination signaling point information, and relevant data;
Among the present invention, signaling equipments such as described STP/SG are meant the functional entity of finishing the signaling forwarding capability, and promptly the signaling capability entity specifically can also can carry based on IP (Internet protocol) based on TDM (time division multiplexing) carrying;
STP/SG equipment is the main equipment that constitutes signaling network, and its function that mainly realizes is that the network layer that realizes signaling message is transmitted, and just at the MTP3 layer message is transmitted processing; The data of described signaling link group data and destination signaling point are present signaling network predetermined data content;
That is to say, what described equipment disposed when configuration signal link group data or destination signaling point data is the corresponding data of logical network, described data are to realize setting according to concrete standard (Q.704 ITU waits) and concrete agreement, and its effect is can correspond to a concrete signaling link group and a destination signaling point according to some information of message when receiving or send signaling message; Described signaling link group is the set that is connected to the signaling link of a concrete signalling point, and signaling link is the actual physics connection to miscellaneous equipment, and the matching process of these data of process can send to correct destination to signaling message;
Specifically can in signaling link group data or destination signaling point data, dispose a logical network sign, reach a logical network configuration table is set in system, identify one that corresponds in the logical network configuration table by logical network, the data of a logical network of concrete configuration in the logical network configuration table, so just, destination signaling point among the STP/SG or signaling link group many groups logically can be divided into, every group of corresponding logical network;
Except that the signaling link group data and destination signaling point data and corresponding logical network identification information of configuration logic network, also need need be configured to down related data for described logical network:
(1) the local exchange signaling point code tabulation of this logical network use: identify the local exchange signaling point code tabulation of this logical network correspondence, i.e. one group of local exchange signaling point code of configuration in the signaling link group data of equipment or in the destination signaling point data; If signaling point code quantity, illustrates that this signaling equipment provides the multiple signaling points code capacity greater than 1, promptly a signaling equipment has a plurality of signaling point codes, and this group local exchange signaling point code also can be configured in the described logical network configuration table;
A subclass of all signaling point codes that described local exchange signaling point code has for this equipment, the miscellaneous equipment in the counterlogic network can be organized signaling point code with this and dock with STP; All corresponding one or more local exchange signaling point code of each logical network like this, if the consensus standard that the Different Logic network uses is identical, signaling point code forms etc. are also identical, the Different Logic network can corresponding identical local exchange signaling point code so, and occuring simultaneously can appear in the local exchange signaling point code of Different Logic network correspondence tabulation just;
For the logical network that needs intercommunication, except the STP node of sharing, on other signaling node, can not use the signaling point code of repetition, to avoid the conflict of signaling point code, causing can't intercommunication;
(2) signaling point code type: being used to identify this logical network interior signaling point coding is 14 or 24.
Step 32: exchanging information at the MTP3 layer between the configuration Different Logic network;
Other logical network tabulation that this logical network can directly realize intercommunication at MTP3 specifically can be set, and which logical network is used to identify this logical network can directly realize intercommunication at MTP3 with;
Also can realize the configuration of logical network that can intercommunication by the mode of a plurality of logical network of configuration in the destination signaling point data under it;
If be not configured to intercommunication, then the signaling traffic between the Different Logic network can not send mutually, and professional mutual isolation between the Different Logic network just is not configured to can not transmit message mutually at the MTP3 layer between the logical network of intercommunication.
Based on above-mentioned configuration, the concrete handling process of the message that the signaling network equipment interconnection is received comprises still as shown in Figure 3:
Step 33: when signaling network equipment is received a signaling message of need transmitting, judge that whether Destination Point Code in the described message is in local signaling point the encoding list, if then execution in step 38, otherwise, execution in step 34;
Step 34: the Destination Point Code in the message of determining to receive is not in the tabulation of this signaling point code any one, then need according to the incoming link group # of signaling message or the OPC information such as (Original Point Code OPCs) of message, in the data of this locality configuration, find the logical network that plays source network number of described message correspondence; Then, also need in the DPC data of information such as (purpose signaling point codings), find the logical network number of the purpose network of this message correspondence in equipment disposition according to message;
Step 35: judge whether two logical network number logical network of the logical network that plays source network number of described message and purpose network (be number) are identical, if it is identical, if promptly play the logical network number that the logical network of source network number equals the purpose network, then execution in step 39, otherwise, execution in step 36;
Step 36: if the above-mentioned logical network that plays source network number is not equal to the logical network number of purpose network, then need to differentiate according to configuration information whether these two logical network are intercommunications, if then execution in step 39, otherwise, execution in step 37;
Step 37 is carried out processing such as necessary statistics or alarm according to predetermined equipment.
Step 38: when equipment receives that one is landed to the non-management class signaling message of this SCCP (SCCP), Destination Point Code in the message is in the tabulation of this signaling point code, then carry out GTT (Global Title translation) process at this point, and execute execution in step 39 after the GTT flow process at SCCP, that is to say the intercommunication that can realize logical network at the SCCP layer fully, needn't be concerned about the origin logical network and the purpose logical network of message;
Step 39: the routing that carries out message is transmitted.
Through the description of said process as can be seen, the present invention has realized the intercommunication of signaling network.
Among the present invention, the realization of logical network and SS7 standard without any conflict, do not rely on the NI in the MTP3 agreement, promptly use the network number that NI supports and mostly be 4 most, and use the logical network function can support theory on the unlimited signaling network of quantity;
Realize the function of intercommunication between the logical network that the present invention can realize linking to each other with signaling point code of this point at the MTP3 layer; Simultaneously, for logical network that can not intercommunication at the MTP3 layer, can adopt prior art can realize intercommunication between the signaling network at the SCCP layer.
In sum, realization of the present invention makes the signalling processing equipments such as STP that different carrier networks can shared same signaling network; And the network that also makes signaling network can become an independent operation provides service for other network; Simultaneously, no matter whether the signaling point code of a plurality of networks distributes and repeats, and all can realize intercommunication at the MTP3 layer for the signaling network that uses same NI.
The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claims.
