The inventive SS7 signaling server for routing SS7 links, includes a signaling
transfer point (STP) and a signaling application server (SAS). STP and SAS have
different functionalities. The STP has at least one external interface to connect
the STP via at least one SS7 link to at least one telecommunications unit, and
an internal interface to connect the STP to the SAS. The STP processes incoming
SS7 messages, e.g. in the SCCP layer. The SAS is capable to process at least one,
advantageously at least two different application service requests. The STP identifies
a single application service request in one incoming SS7 message and provides the
identified single application service request to the SAS for further processing.
The SAS has e.g. two TCAP processes to identify two different application services,
e.g. INAP and MAP. STP and SAS are interconnected via an internal interworking
protocol, e.g. using TCP/IP.
