- Signalling Connection Control Part
This allows non-circuit related signalling (such as TCAP) to be carried over SS7 routes.
- Service Creation Environment
This allows the creation of services in an SS7 Intelligent Network environment.
- Service Control Point (SS7)
Service Control Points contain centralized network databases for providing enhanced services. The SCP accepts queries from the Service Switching Point (SSP) and returns the requested information to the requester.
- Synchronous Data Link Control
- Symmetric Digital Subscriber Line
- Signalling Endpoint
- Status Field
- Service Indicator
- Service Independent Building Blocks
In the area of SS7 based Intelligent Networks this refers to the abstract representation of IN capabilities that allow IN services to be built.
- Signalling Information Field
- Subscriber Identity Module
In GSM networks a subscriber is associated with a mobile station via the means of a personal chip card.
- Signalling Information Octet
SIO contains information on the identity of the user of an SS7 MTP message - eg. ISUP, TCAP
- Session Initiation Protocol
SIP is an IETF initiative that provides an alternative to the H.323 standard for VoIP signalling.
- Signalling Link Code
- Short Message Peer to Peer
This protocol allows communication into and between SMSC's. Often this protocol is provided as a means of providing third party SMS applications with single or bulk SMS delivery.
- Short Message Service
A text message service that enables short messages of generally no more than 140-160 characters in length to be sent and transmitted from a cell phone. In a GSM network this service is enabled by the SS7 MAP Protocol.
- Short Message Service Centre
A node in the network that receives all mobile originated text messages, determines the current status of the recipient, forwards the message to the appropriate destination subscriber, or stores them for later transmission.
- Simple Mail Transfer Protocol
- Simple Network Management Protocol (IETF)
- Signalling System #7
SS7 is a global standard for telecommunications defined by the International Telecommunication Union (ITU) Telecommunication Standardization Sector (ITU-T). It provides protocol signalling standards for both fixed and cellular networks allowing for circuit based telephony calls and transaction based services - i.e. delivery of SMS, Intelligent Network Services.
- Service Switching Point
Service Switching Points are telephone switches interconnected by SS7 links. SSPs perform call processing on calls that originate, tandem, or terminate at that site. SSPs generate SS7 messages to transfer call-related information to other SSPs or to query an SCP for routing instructions.
- Signalling Transfer Point
Signal Transfer Points are switches that relay messages between network switches and databases. Their main function is to route SS7 messages to the correct outgoing signalling link, based on SS7 message address fields.
