Embodiment 1

[0058] Referring to FIG. 5A, the OPC code of the initial signaling point SP1 is 0000, and the OPC code of SP2 is 0001. SP1 and SP2 forward the message with the SLS as an even number through STP1, and forward the message with the SLS as an odd number through STP2. STP1 and SP2 There are 16 links configured in the link group between STP2 and the destination signaling point. At this time, the number of SLS identification types of messages received by STP1 and STP2 is 8, which is less than the number of 16 links that can be selected. This method can be applied The method for binding the SLS identifier and OPC provided by the embodiment of the invention calculates the virtual SLS identifier of the message arriving at STP1 and STP2, and selects a link to carry the message according to the virtual SLS identifier of the message. The specific implementation method is as follows:

[0059] Configure link group extended route selection parameters for STP1 and STP2. The SLS identifiers of ...

Embodiment 2

[0064] Referring to Fig. 6A, the OPC code of the initial signaling point SP1 is 0000, the OPC code of SP2 is 0001, the OPC code of SP3 is 0010, the OPC code of SP4 is 0011, and SP1 and SP3 pass the message of SLS identification as 0000-0111 Forwarded by STP1, the message identifying SLS as 1000-1111 is forwarded through STP2, and SP2 and SP4 forward the message identifying SLS as 1000-1111 through STP1, and the message identifying SLS as 0000-0111 is forwarded through STP2, and STP1 and STP2 forward SLS The message identified as 0000-0011 is forwarded through STP3, the message identified as SLS 0100-0111 is forwarded through STP4, the message identified as SLS 0100-1011 is forwarded through STP5, and the message identified as SLS 1100-1111 is forwarded through STP6. There are 16 links configured in the link group between STP3, STP4, STP5 and STP6 and STP7 and STP8. At this time, the types of SLS identifiers that STP3, STP4, STP5 and STP6 can receive messages are all 4, which is...

Embodiment 3

[0089]Still referring to Fig. 5A, the GT code height 4 bits of the message sent by the initial signaling point SP1 is 0001, and the GT code height 4 bits of the message sent by SP2 is 0010, and SP1 and SP2 forward the message that SLS is marked as an even number through STP1, and the SLS Messages marked with an odd number are forwarded through STP2, and the link group between STP1 and STP2 and the destination signaling point is configured with 16 links. At this time, the types of SLS signs received by STP1 and STP2 are both 8 types, less than The number of links that can be selected is 16. The method of binding the SLS identifier and the message GT code provided by the embodiment of the present invention can be used to calculate the virtual SLS identifier of the message arriving at STP1 and STP2, and select a link to carry the message according to the virtual SLS identifier of the message. message, the specific implementation method is as follows:

Abstract

The invention comprises: a receiving unit used for receiving the message containing signaling link selection (SLS) identifier and distinguishing identifier; a route selection unit used for selecting at least two links for the message containing same SLS identifier according to the SLS identifier and distinguishing identifier; a bearer unit used for using the selected at least two links to bearing said message. The distinguishing identifier comprises the originating point code (OPC), or the global translation (GT) code, or service indication (SI) identifier.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for selecting a message bearing link and a signaling transfer point. Background technique [0002] Under the definition of the No. 7 signaling protocol of the International Telecommunication Union (ITU), the message transfer (MTP3) layer needs to deliver messages in order. The so-called order delivery is based on the signaling link selection (SLS) identification of the message. Yes, messages with the same SLS identifier are transmitted on the same link, and messages with different SLS identifiers are transmitted on different links. [0003] The SLS identifier is represented by a binary number, and the length of the SLS identifier stipulated by different protocols is different. The length of the SLS identifier stipulated by the ITU protocol is 4 bits (bits), so there are 16 different SLS identifiers in total. [0004] In the MTP3 layer, the message sent by the sou...
