Claim:
1. A method for redirecting roaming network traffic in one or more telecommunication networks, the method comprising: observing, by a module deployed in a home network, a registration process of a subscriber in a first visited network, the registration process including transmission of a Diameter Update Location Request message by the first visited network to the home network and transmission of a Diameter Update Location Update message by the home network to the first visited network; identifying, by the module deployed in the home network, whether the subscriber is registered on a Long Term Evolution (LTE) network or a Global System for Mobile communications (GSM) network; if the subscriber is registered on the LTE network, attempting to redirect the subscriber to a different LTE network; if the subscriber is registered on the GSM network, then determining whether the registration of the subscriber is due to loss of LTE coverage or circuit-switched fallback (CSFB); if the registration of the subscriber is due to CSFB, then allowing the subscriber to be registered on the GSM network; and if the registration of the subscriber is due to the loss of LTE coverage, then sending, by the module deployed in the home network, one or more messages to the first visited network that includes a request with an operator determined barring (ODB) parameter that induces the first visited network to send a detach request to the subscriber to detach from the first visited network and attempt a registration with a second visited network.
