Description
Technical field
The present invention relates to the communication technology, method, system and equipment that particularly a kind of message transmits.
Background technology
No.7 signalling system (No.7) is worked out by CCITT, it is a kind of international standard common channel signalling system, have advantages such as transmission speed is fast, signaling capacity is big, function is strong, flexibility and reliability, can fully satisfy the requirement to signaling such as telephone network (PSTN), land mobile communication network (GSM), Intelligent Network.No.7 mainly can be divided into following two parts:
● public Message Transfer Part (MTP), it is for providing the reliable delivery of signaling message between each user function.
● be fit to the isolated user part of different user, it is to use the functional entity of Message Transfer Part transmission capacity, is used to realize various call business.Comprise ISDNYong Hubufen (ISUP), intelligent network application part (INAP), MAP (MAP) etc.
Wherein, the major function of Message Transfer Part (MTP) is that reliable signaling message transmission is provided in signaling network, and under system and signaling network failure condition, for guaranteeing reliable information transmission, takes measures to avoid or reduces information drop-out, repeats and out-of-sequence.It is made up of signaling data link (MTP1), signaling link function (MTP2) and three functional levels of signaling network functions (MTP3).
SCCP abbreviates SCCP (Signaling Connection Control Part) as.In the hierarchy of No.7 signaling method, it is one of User Part, belong to the 4th function group, provide additional function for MTP simultaneously, so that by the relevant information relevant of No.7 signaling network transfer circuit between the exchange of telecommunications network and special-purpose center and the information of other type with inverter circuit, set up not have and connect or connection-oriented business the 3rd layer (network layer) in the formation OSI hierarchical mode.
In the No.7 signaling network, each signalling point is by the signaling point code unique identification; But, in SCCP, can use global title (Global Title is the GT sign indicating number) to realize route.The GT sign indicating number provides addressing system flexibly for SCCP, and is all meaningful in global scope, can realize direct transfer circuit irrelevant messages between interior any two signalling points of global range.
The GT sign indicating number does not mainly use under origination node is known the situation of meshed network address, destination, can identify any one signalling point of the whole world and/or subsystem.When SCCP used GT coding mode route, the SCCP message processing device need be translated into called GT sign indicating number signaling point code and deliver the MTP transmission again.
When SCCP message during from a forwarded to another network, the SCCP message processing device could send after need making certain modification to the GT sign indicating number.What prior art adopted is the method for shining upon one by one, and as shown in Figure 1: a new GT sign indicating number of former GT sign indicating number configuration that need change for each bar is corresponding with it.The SCCP message processing device utilizes this corresponding relation to convert former GT sign indicating number to new GT sign indicating number, and transfer process can be by searching former GT sign indicating number and the correspondence table realization of GT sign indicating number newly.Adopt this method, if mutual service needed is changed a large amount of GT sign indicating numbers in the network, the new GT sign indicating number that the SCCP message processing device must dispose a large amount of GT sign indicating numbers and be used to replace them, a large amount of GT sign indicating number conversions influence the handling property of system.
