Abstract: A method for load sharing class 1 SCCP messages includes receiving a class 1 SCCP message requiring global title translation (GTT). The method includes performing GTT for the message to select a load sharing group for the message. The method further includes generating a message signal unit (MSU) load sharing key using parameters from a combination of message transfer part (MTP) layer parameters and signaling connection control part (SCCP) layer parameters. The method further includes using the MSU load sharing key to select a destination address from the load sharing group for the message. The method further includes inserting the destination address into the message. The method further includes routing the message to a destination corresponding to the destination address.

Abstract: Methods, systems, and computer readable media for short message delivery status report validation are disclosed. One method occurs at a first network node. The method includes receiving a short message delivery status report appearing to be associated with a short message delivery to a mobile subscriber; determining, using a data store containing information about short message delivery attempts, whether the short message delivery status report is valid or invalid, wherein the information about the short message delivery attempts indicates a validation time period for receiving a valid short message delivery status report; and performing a processing action based on the determination.

Abstract: A method for conducting a velocity check for outbound subscribers roaming to neighboring countries includes receiving, by a network gateway associated with a home country from an MSC associated with a neighboring country, an ingress signaling message related to a mobile device roaming in the neighboring country, sending, to an HLR in the home country, an interrogation request message containing a mobile subscriber identifier, and receiving an interrogation response message containing age of location information and cell identifier information corresponding to the mobile subscriber identifier.
