A mobile messaging operator is a specialized form of mobile network operator that provides mobile messaging services such as SMS or Multimedia Messaging Service to businesses or other mobile operators. Types of mobile messaging operators There are two types of mobile messaging operators, aggregators and SS7 Signaling System 7 providers. The aggregator model involves the mobile messaging operator signing multiple individual agreements with mobile operators to facilitate two way SMS traffic through that operator s SMSC Short Message Service Center . SMS messages are delivered to the operator s SMSC, but not the subscriber s handset the SMSC takes care of further handling of the message through the SS7 network. The SS7 model enables mobile messaging operators to route data directly through the SS7 system, giving the provider greater control and visibility of the transmission path during SMS routing. In this way, SMS messages can be sent directly to and from recipients without having to go through the SMSCs of other mobile operators. Some mobile messaging operators also operate a mixed model, combining SS7 and aggregated connectivity. Uses of mobile messaging operators Mobile messaging operators can provide businesses or other mobile operators with a range of messaging services, including SMS transmission and reception Short codes and long numbers Mobile ticketing Mobile authentication services Two factor authentication Wireless Tokens Premium rate SMS services Premium rate SMS Premium rated short messages SMS Voting Mobile interaction services See also SMS SMS gateway SMSC Mobile network operator Bulk messaging Signaling System 7 Category Telecommunications ... more details

unreferenced date January 2011 A service control point SCP is a standard component of an intelligent network IN telephone system which is used to control the service. Standard SCPs in the telecom industry today are deployed using SS7 , Sigtran or Session Initiation Protocol SIP technologies. The SCP queries the Service Data Point service data point SDP which holds the actual database and directory. SCP, using the database from the SDP, identifies the geographical number to which the call is to be routed. This is the same mechanism that is used to route 800 number s. SCP may also communicate with an intelligent peripheral IP to play voice messages, or prompt for information to the user, such as prepaid long distance using account codes. This is done by implementing telephone feature code s like , which can be used to terminate the input for a username or password or can be used for call forwarding . These are realized using INAP intelligent network application protocol INAP that sits above Transaction Capabilities Application Part transaction capabilities application protocol TCAP on the SS7 protocol stack. The TCAP is part of the top or 7th layer of the SS7 layer breakdown. SCPs are connected with either Service switching point SSPs or Signal transfer point STPs . This is dependent upon the network architecture that the network service provider wants. The most common implementation uses STPs.

In telephony , a Service Switching Point SSP is the telephone exchange that initially responds, when a telephone caller dials a number, by sending a query to a central database called a Service Control Point SCP so that the call can be handled. The Service Switching Point uses the Signalling System 7 SS7 protocols which are responsible for the call setup, management, and termination with other Service Switching Points. Relationship between SSP and SCP With the introduction of the intelligent network architecture, service functionality e.g. UK translation of 0800 non geographic telephone numbers is being removed from the actual telephone exchange and devolved out into other computer nodes. In this new architecture, the telephone exchange is known as an SSP and the node that contains the services and hence controls the progression of a call is known as Service Control Point SCP . Example of a 0800 Number Translation service In the UK 08XXX numbers are non geographic numbers that is, the number does not refer to a telephone number in any particular region of the UK. To route a call to such an 08XXX number, the number must be translated into a geographic number e.g. 0121 XXX XXXX for Birmingham numbers . An SSP telephone exchange receives a call to an 0800 number. This causes a trigger within the SSP that causes an SCP Service Control Point to be queried using SS7 protocols INAP , Transaction Capabilities Application Part TCAP . The SCP responds with a geographic number, e.g. 0121 XXX XXXX, and the call is actually routed to a phone. By this architecture 08XXX non geographic numbers can be set up in a few SCP nodes rather than having to be set up in every telephone exchange in the country. geographic numbers can be hidden revenue can be generated by non telecoms companies from people making telephone calls to services e.g. telephone voting External links http www.iec.org online tutorials ss7 SS7 Tutorial Signalling Architecuture, including SSP description.

In telephony, Common Channel Signaling CCS , in the US also Common Channel Interoffice Signaling CCIS , is the transmission telecommunications transmission of Signaling telecommunication signaling information control information on a separate channel from the data, and, more specifically, where that signaling channel controls multiple data channels. ref harv Ronayne 1986 p 141 . ref For example, in the public switched telephone network PSTN one channel of a communications link is typically used for the sole purpose of carrying signaling for establishment and Clearing telecommunications tear down of telephone call s. The remaining channels are used entirely for the transmission of voice data. In most cases, a single 64kbit s data link channel is sufficient to handle the call setup and call clear down traffic for numerous voice and data channels. ref harv Ronayne 1986 p 145 . ref The logical alternative to CCS is Channel Associated Signaling CAS , in which each bearer channel has a signaling channel dedicated to it. CCS offers the following advantages over CAS, in the context of the PSTN ref harv Ronayne 1986 p 142 . ref Faster call setup. No falsing interference between signaling tones by network and speech frequencies. Greater trunking efficiency due to the quicker set up and clear down, thereby reducing traffic on the network. No security issues related to the use of in band signaling with CAS. CCS allows the transfer of additional information along with the signaling traffic providing features such as caller ID . The most common CCS signaling methods in use today are Integrated Services Digital Network ISDN and Signaling System 7 SS7 . ISDN signaling is used primarily on trunks connecting end user private branch exchange PBX systems to a central office . SS7 is primarily used within the PSTN. The two signaling methods are very similar since they share a common heritage and in some cases, the same signaling messages are transmitted in both ISDN and SS7. CCS is dist ... more details

Transport conversion is often from Signaling System 7 SS7 to Internet Protocol IP . A SIGTRAN Signaling Gateway is a network component that performs packet level translation of signaling from common channel signaling based upon SS7 to SIGTRAN signaling based upon IP . The concept of the SIGTRAN signaling gateway was introduced in the Internet Engineering Task Force IETF document RFC 2719 Architectural Framework for Signaling Transport. A signaling gateway can be implemented as an embedded component of some other network element, or can be provided as a stand alone network element. For example a signaling gateway is often part of a softswitch in modern Voice over Internet Protocol VoIP deployments. The signaling gateway function can also be included within the larger operational domain of a Signal Transfer Point Signal Transfer Point STP . Protocol conversion gateways can also convert from one network operational paradigm to another for example, Session Initiation Protocol SIP to ISDN User Part ISUP for call control , SIP to Transaction Capabilities Application Part TCAP for address translation, or SIP to MAP for location or presence.
