Abstract
A message interworking gateway (1) resides in an overlay IMS network (2) associated with a home SS7 network (10). The gateway (1) intercepts requests for routing information (MAP-SRIs) from either the home SMSC (11) or a foreign SMSC. If the message recipient is available on the IMS overlay network (2) the gateway (1) performs protocol translation AND routes the translated message to the recipient. If not, the gateway returns the SRI to the home (10) network. The gateway operates without updating the home HLR (12) with user presence data and hence voice traffic can be kept on circuit switched technology without being routed to the IMS overlay network (2).
