Abstract: Methods and systems for load sharing signaling messages at the MTP level are disclosed. When a signaling message is received, it is determined whether the signaling message includes a routing indication indicating route-on-point-code-subsystem-number. If the routing indicator indicates route-on-point-code-subsystem-number, it is determined whether the signaling message belongs to an MTP level 3 load sharing group. If the signaling message belongs to an MTP level 3 load sharing group, the signaling message may be routed to any of the point codes in the MTP level 3 load sharing group. Routing the signaling message to a point code in the MTP level 3 load sharing group may include replacing the destination point code in the signaling message with the destination point code of the node to which the signaling message is to be routed. Once the point code has been replaced, the signaling message is routed to the destination associated with the point code.
