A METHOD AND SYSTEM FOR MESSAGING IN EVENT OF CONGESTION IN MOBILE NETWORKS

摘要

This invention provides resource sharing across multiple mobile networks by routing incoming (submitted messages) towards an external SMSC for delivery when the local resource is unavailable or fully utilized. For example, incoming messages can be routed to an external SMS function for safe storage and later delivery attempt to maximize SMS service quality and revenue. Determination of available external resources is achieved by use of a routing table that may be static (in the simple case) or dynamic (in the case where only the "spare" remote capacity is offered) that is shared in a reciprocal manner with each opted-in entity. Local network SMS-MO routing can selectively divert messages to the external SMS delivery resources, most typically after any billing is performed. The delivery to the external resource can be via MO-SMS (SS7/MAP) or IP (SIGTRAN/SMPP) depending on preference and locale. By offloading the MO message to another SMSC, local bandwidth usage is improved given that the MO message is only 2 transactions (MO & MO-ACK) compared with the 4 transactions for delivery. This presents the local network with a reduced transaction loading per unit time, than if the delivery is made synchronously by the local network. Therefore, the local network becomes more efficient under the extreme load.
