Digital telecommunications system for the creation, integration, management, deployment, activation, grouping and orchestration of services from various services platforms with different orchestration logics or of services according a variety of combinations between the services, the system being an applications and services system, said MULTISERVICES NETWORK CENTER, located within at least one mobile telecommunications core network, said MULTISERVICES NETWORK CENTER comprising: - At least one module applications and services orchestration server, said Network Browser, comprising an least one module calls control and orchestration server, said CCB module and at least one module logic orchestration and services integration server, said LIB module, said services: ∘ being mobile networks services, fixed, IP, convergent, new generations and/or telecommunications core network services; ∘ being compliant with at least one standard protocol; - at least one module network gateway communicating with said Network Browser and linking said Network Browser to at least one set of elements of said mobile telecommunications core network; - at least one module integration gateway, communicating with said Network Browser et linking said Network Browser through at least one IP network with at least one module of telecommunications operators services or of third parties and/or with at least one module of mobile value added services; - at least one module database and profiling, communicating with said Network Browser, and comprising at least one functionality for definition of at least one services logic profile, the services logic being the rules of combinations and sequences of services; and - at least one administration module, communicating with said Network Browser, with said module network gateway, with said module integration gateway and with said module database and profiling, and comprising control functionalities of said MULTISERVICES NETWORK CENTER and configuration functionalities of said modules database and profiling, network gateway and integration gateway, the administration module also comprising a logic of grouping and orchestration of services and a services creation environment; said MULTISERVICES NETWORK CENTER being: - a system connected to at least one services platform such as SMSC, WAP gateway, OTA gateway, IVR module and/or GPRS module; - a charging and billing system in real time, comprising at least one charging module, and/or at least one billing module, and/or at least one observation and ranking module, said modules being linked to the Network Browser; - a system wherein the Network Browser comprises functions of multiple actions triggering per call type, said triggering being defined in the database and profiling module and used by the Network Browser to execute and to control different services related to a call type; - a Proxy system performing signaling for a part or for a set of messages of the mobile telecommunications network. - At least one module applications and services orchestration server, said Network Browser, comprising an least one module calls control and orchestration server, said CCB module and at least one module logic orchestration and services integration server, said LIB module, said services: ∘ being mobile networks services, fixed, IP, convergent, new generations and/or telecommunications core network services; ∘ being compliant with at least one standard protocol; ∘ being mobile networks services, fixed, IP, convergent, new generations and/or telecommunications core network services; ∘ being compliant with at least one standard protocol;
