Abstract
A short message service (SMS) network allows more than one short message service center (SMSC) to service an individual subscriber with virtually no modification to the existing conventional network elements, e.g., the home location register (HLR) or the mobile switching center (MSC).

Each of the plurality of SMSCs in turn delivers short messages to an intended subscriber, and then forwards the notification signal to another one of the SMSCs, until all of the SMSCs have delivered the respective pending short messages. The next SMSC to which the SMSNOT is forwarded may be fixedly determined, e.g., by network configuration. Moreover, the path for forwarding the SMSNOT signal may be reconfigured when one or more SMSCs are added to the SMS network. Alternatively, the forwarding path may be determined dynamically by the preceding SMSC in accordance with an intelligent rule based on paramet…
