Description
Technical field
The present invention relates to No.7 signalling system, particularly a kind of route coding method of signaling message and device.
Background technology
No.7 signalling system is also referred to as No.7 signaling system (SS7, Signalling System No.7), is the interoffice common channel signalling, is applied to digital communications network.No.7 signalling system defines in ITU Q serial protocols, and as shown in Figure 1, the Signaling System Number 7 protocol stack comprises User Part (UP, User Part) and Message Transfer Part (MTP, Message Transfer Part).The Signaling System Number 7 User Part mainly comprises MAP (MAP, Mobile Application Part) or intelligent use part (CAP), things ability applying portion (TCAP, Transcation Capability Application Part), ISUP (ISUP, ISDN User Part) or Telephone User Part (TUP, TelephoneUser Part), SCCP (SCCP, Signalling Connection Control Part).Different User Parts can carry out combining and configuring according to the different demand of user, such as: the network entity that comprises MAP, things ability applying portion, SCCP and Message Transfer Part can be handled the MAP affairs; The network entity that comprises SCCP and Message Transfer Part can be used as the switching task that Signalling Transfer Point (STP, Signalling Transfer Point) is finished signaling; The network entity that comprises ISUP and Message Transfer Part then can be handled the ISUP affairs.Certainly, network entity also can comprise the protocol section that can handle multiple affairs simultaneously.Fig. 2 has shown typical network entity in the Signaling System Number 7 net, the function of each several part was when network entity outwards sent business datum: move and use or intelligent use part 201, be used for the business datum of input is encoded to MAP or CAP message, and export to transaction-capable applying portion 202; Transaction-capable applying portion 202 is used for the message of input is further encoded, and exports to SCCP 203; SCCP 203 is used for carrying out routing according to the message of input to be handled, and exports to Message Transfer Part 205; ISUP or Telephone User Part 204 are encoded to ISUP or TUP message with business datum, and export to Message Transfer Part 205; Message Transfer Part 205 transmits the message of input reliably, promptly sends to the purpose network entity of message.Wherein, when business datum is relevant mobile application or intelligent use part affairs, just use or 201 processing of intelligent use part by moving, when business datum is relevant ISUP or Telephone User Part affairs, then handle by ISUP or Telephone User Part 204.Certainly, in the practical application, network entity can also receive message, and is reciprocal when the process of reception message and the function of each several part and transmission message.
The Signaling System Number 7 net is made up of signalling point (SP, Signalling Point), Signalling Transfer Point (STP, SignallingTransfer Point) signaling link (SL, Signalling Link) three parts.Wherein, signalling point SP is the node of control message processing, and the signalling point that produces message is the originating point of this message, and the signalling point that message arrives is the destination of this message; Signalling Transfer Point STP has the signaling forwarding capability, signaling message can be transferred to another signaling link from a signaling link; Signaling link SL transmits the link of signaling message between two signalling points, and directly connects a branch of signaling link group of signaling link formation or the route of two signalling points.
The regulation of Signaling System Number 7 agreement, two associated signaling points have only a link group.Use between origin signalling coding (OPC, Original Point Code) and the Destination Point Code (DPC, Destionation PointCode) and represent that the straight line of a link group couples together.Because agreement regulation signaling link selects (SLS, Signalling Link Selection) to represent with 4 bits, so have only 16 links in the link group between two associated signaling points, the maximum bandwidth that information transmits is 16 * 64Kbit/s.Along with can only be professional, the development of mobile communication, the signaling traffic between two signalling points is increasing, the maximum bandwidth of stipulating in the agreement can not satisfy the demand of reality, and has become one " bottleneck " of modern communications.
In application numbers is a kind of method to multipoint encoding for number 7 signaling point that proposes in 021208093 the patent application, has broken through the maximum bandwidth of stipulating in the Signaling System Number 7 agreement.The specific practice of this method is at the local exchange that sends message n logic signalling point to be set, and stipulates that each logic signalling point all is connected with destination signaling point according to the single-point equipping rules of Signaling System Number 7 agreement, wherein n≤16.With Fig. 3 is example, this method is provided with three logical source signalling points in the Original Signaling Point OPC of A office, its signaling point code is respectively 111111,222222,333333, they are encoded to 444444 destination signaling point DPC by a link group and B office signaling point respectively and are connected.According to the single-point equipping rules of Signaling System Number 7 agreement, each bar link group can dispose 16 links at most, and so, local exchange Original Signaling Point OPC just can dispose 16 * 3 links at most to the destination signaling point DPC that plays a game, thereby has realized the expansion of traffic load ability.
But, the method that No. 021208093 patent application proposes has only been considered to expand the traffic load ability at Message Transfer Part with a plurality of signalling points, and do not have to consider when multiple signaling points are applied in the network entity that comprises higher protocol sections such as MAP/CAP/TCAP/ISUP/TUP, how MTP should use the multiple signaling points coding techniques with the protocol section on top, should and how a plurality of signalling points be selected by which part.If do not consider these above-mentioned problems, so, also just can not bring into play the professional ability that has expanded well at the network entity that comprises higher protocol section.
In addition, when network entity transfer message, prior art generally is to give the middle signalling point that can arrive destination signaling point by the Original Signaling Point that receives message in this network entity with forwards, and then is transmitted to destination signaling point by middle signalling point.Do not receive message if exist in the network entity, but can directly arrive the Original Signaling Point of destination signaling point the time, prior art just can not make full use of the multiple signaling points of present networks entity, has wasted resource and transmission time.
This shows that prior art does not also have to propose to use the effective ways of multiple signaling points coding in having the network entity of higher protocol section.
