Abstract: A filtering and application triggering platform may be implemented on a signaling message routing node to decode signaling messages and increase efficiency in subsequent processing of the signaling message. A communications link module on a signaling message routing node receives a signaling message. A first filtering and application triggering module associated with the communication link module extracts predetermined parameters from the signaling message and generates a decode key based on the parameters. The first filtering and application triggering module applies a first triggering rule to the decode key and determines whether to forward or drop the message. If the first filtering and application triggering module determines that the message should be forwarded, the first filtering and application triggering module forwards the message to another processing module within the signaling message routing node. The decode key is forwarded along with the message.

Abstract: Methods and systems for migrating between application layer mobile signaling protocols are disclosed. For subscribers of multiple protocols, the registration status is tracked in one or more of the protocols. When a location query message for a subscriber of multiple protocols is received, it is determined whether the subscriber is registered according to the tracked protocol. If the subscriber is registered according to the tracked protocol and the request originated from an MSC of the tracked protocol, the message is routed to an HLR of the tracked protocol. If the subscriber is not registered according to the tracked protocol, a response is formulated to the first message. The response optionally includes a prefix that directs the originating MSC to route the call to an MSC of the non-tracked protocol.

Abstract: A routing node communicates between subscribers of different application-layer mobile communications protocols, such as IS-41 and GSM, without converting each IS-41 message to GSM and vice versa. Rather than converting each message to the protocol of the intended recipient, the routing node functions as an HLR to provide the location of a mobile subscriber in a different application-layer mobile communications protocol and as an MSC to forward short message service messages to a short message service center of the other application-layer mobile communications protocol.
