Abstract: A message center for source-based message routing may include a processor and a memory communicatively connected to the processor. The processor may be configured to receive a first message having a first message transfer layer indicating a first destination address and a first message transaction layer, receive a second message having a second message transfer layer indicating a second destination address and a second message transaction layer indicating an alternate routing, read at least the first message transfer layer of the first message, read at least the second message transaction layer of the second message, route the first message based in part on the first destination address of the first message transfer layer, and route the second message based in part on the second destination address of the second message transfer layer and the alternate routing of the second message transaction layer.

Abstract: A method performed by a network device may include receiving a mobile directory number (MDN) that has been identified as a mobile spam originator and generating a query for attributes of a mobile device registered with the MDN. The method also includes receiving a query response that include attributes of the mobile device and determining to block the mobile device from access to a network associated with the network device. The method further includes providing, by the network device and to a blacklist system, one or more of the device attributes.

Abstract: Systems and method for identifying and blocking short messaging service spam are disclosed. In some aspects, a first mobile messaging service message is received from a messaging source in a node of a mobile communication network, the first mobile messaging service message being addressed to a destination mobile device. The first mobile messaging service message is forwarded through the mobile communication network for delivery to the destination mobile device. Whether or not the first mobile messaging service message meets a spam messaging criterion is determined, where determining whether or not the first mobile messaging service message meets the spam messaging criterion occurs in parallel with forwarding the first mobile messaging service message through the mobile communication network. Information identifying the messaging source as a spam source is stored, upon determining that the first mobile messaging service message meets the spam messaging criterion.
