Description
Technical Field
The invention relates to the field of signaling networks, in particular to a method for realizing that a Global Title (GT for short) is published by a local point with a plurality of signaling points.
Background
In a signalling network, signalling points are used to uniquely identify a device in a signalling network, and GT is a number that uniquely identifies a device globally. By data configuration, a GT can be uniquely translated to a certain signaling point. A link is a channel for communication between signaling points, and the protocol specifies a maximum of 16 links between two signaling points.
With the development of telecommunication data service, at most 16 64k signaling links between two signaling points in the original signaling network are far from meeting the service requirement. Therefore, high-speed signaling link technologies such as Asynchronous Transfer Mode (ATM) 2M link, chinese 2M link, etc. are generated to expand the signaling link bandwidth in the narrowband signaling network. From the practical use situation, the signaling capacity between signaling points is increased to 16 times after the high-speed signaling link technology is used. But the technique does not address the limitation of up to 16 signaling links between 2 signaling points. Thus, multiple signaling point techniques have also been developed. Therefore, a service center can simultaneously have a plurality of local signaling points, and at most N × 16 links can be arranged between the service center and a destination signaling point. In theory, this technique extends the signaling access capacity of the device indefinitely.
However, due to protocol specifications, a GT can only be translated to one signaling point, i.e. each signaling point in a multiple signaling point technology must have a separate GT. Therefore, some devices that need to publish GT externally introduce multiple signaling points technology, which is inconvenient or even unacceptable for daily use. For example, if a provincial large-capacity short message center needs to publish a plurality of short message center numbers to provincial users at the same time after using the multi-signaling point technology, it is not acceptable for operators and users.
In the prior art, when a multi-signaling point function is used, for a central office point which cannot publish two or more GT codes, such as a short message service center, only one GT is published externally. The signaling points corresponding to the GT are only used for processing services initiated by service trigger points (uplink flows in short message services), and the signaling points corresponding to other GTs are used for processing services initiated by office points (downlink flows in short message services).
As shown in fig. 1, a local Point publishes a GT, and a service trigger Point uses the GT to trigger an actively initiated service to a local Point signaling Point 1 through a thick line link between a Signaling Transfer Point (STP) and the local Point; the office uses GT2 and office signaling point 2 to route the actively initiated traffic to other nodes of the network via STP and inter-office thin line links.
The prior art has the disadvantages that the service initiated by the service trigger point can only use one signaling point of the local point, and the local point with large capacity still has the possibility of being insufficient; in addition, a plurality of GT is required to be distributed at the local point, and the network planning is more complex.

Detailed Description
In order that the invention may be more readily understood, specific embodiments thereof will be described herein below with reference to the accompanying drawings.
Fig. 2 shows a signaling flow of implementing a central office with multiple signaling points publishing a GT by service trigger point grouping when STP has no load sharing function in a network.
In the network that the present network STP does not support GT translation load sharing function, when the service trigger point uses GT to local point to trigger service, the GT in the message is directly translated to the local point. At this time, the translation type of the GT on the service trigger point is DPC, and the DPC is set as the signaling point with different local points according to the difference of the group.
After receiving the message, STP does not translate GT, and sends the message to the signaling point corresponding to the local point according to DPC information in the message.
After receiving the message, the local point firstly records the signaling point receiving the message and then carries out service logic processing. When the local point returns the message to the service trigger point after finishing the processing, the GT is used as the calling address in the message, then the signaling point receiving the trigger service message is obtained by recording the information, finally the return message is sent to the STP by the signaling point, and then the STP forwards the return message to the service trigger point.
Fig. 3 shows a signaling flow for implementing the publication of a GT by a bureau point having multiple signaling points via service trigger point packets without STP in a network.
In a network without STP, when a service trigger point triggers a service using a GT to a local point, the GT in the message is first translated to the local point and the message is sent to the signaling point. At this time, the translation type of the GT on the service trigger point is DPC, and the DPC is set as the signaling point with different local points according to the difference of the group.
After receiving the message, the local point firstly records the signaling point receiving the message and then carries out service logic processing. When the local point returns the message to the service trigger point after finishing the processing, the GT is used as the calling address in the message, then the signaling point receiving the trigger service message is obtained by recording the information, and finally the return message is sent to the service trigger point by the signaling point.
Fig. 4 shows a signaling flow of implementing a central office point having multiple signaling points publishing a GT in a network where STP supports load sharing functionality.
In the network of present network STP supporting GT translation load sharing function, when the service trigger point uses GT as the called address to trigger service to the local point, the GT in the message is translated to STP first, and then the STP continues to process the message. At this time, the translation type of GT on the service trigger point is DPC + original GT, and DPC is the signaling point of STP. After receiving the message, STP uniformly forwards the service to all signaling points of the local point according to the translation result of GT. At this time, the translation type of the GT on the STP is DPC or DPC + original GT, some STPs only support the load sharing between the two DPCs when the GT translation result is DPC + original GT, and some STPs support the load sharing between the two DPCs when the GT translation result is DPC + original GT or DPC. The translation form used in practical application needs to be determined according to networking specifications and STP capability. The DPC is an office point to a signaling point.
After receiving the message, the local point firstly records the signaling point receiving the message and then carries out service logic processing. When the local point returns the message to the service trigger point after finishing the processing, the GT is used as the calling address in the message, then the signaling point receiving the trigger service message is obtained by recording the information, finally the return message is sent to the STP by the signaling point, and then the STP forwards the return message to the service trigger point.
Fig. 5 shows a signaling flow of implementing a plurality of signaling points in a central office publishing a GT in a network without STP and with a service trigger point supporting a load sharing function.
In a network without STP and with a service trigger point supporting GT translation load sharing function, when the service trigger point uses GT as a called address to trigger service to a local point, the service is uniformly forwarded to all signaling points of the local point according to the translation result of the GT. At this time, the translation type of the GT on the service trigger point is DPC or DPC + original GT, some STPs only support load sharing between two DPCs when the GT translation result is DPC + original GT, and some STPs support load sharing between two DPCs when the GT translation result is DPC + original GT or DPC. The translation form used in practical application needs to be determined according to networking specifications and STP capability. The DPC is an office point to a signaling point.
After receiving the message, the local point firstly records the signaling point receiving the message and then carries out service logic processing. When the local point returns the message to the service trigger point after finishing the processing, the GT is used as the calling address in the message, then the signaling point receiving the trigger service message is obtained by recording the information, and finally the return message is sent to the service trigger point by the signaling point.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
