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.
