It is an object of the invention to provide an advantageous SAS Service Architecture. The inventive SAS service architecture has a layered structure including a set of software modules, at least: ASTP dispatcher, SCCP transcoder, TCAP, TCAP user service distributor, at least two TCAP user services; ASTP=specific advanced signaling transfer protocol including routing information, etc. Within the SAS service architecture at least two different types of interactions can be configured: interaction Type A between ASTP dispatcher and TCAP user service, interaction Type B1 between TCAP user serviceand TCAP user service

SAS service architecture

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.
