first IMS version (IMS Release 5) to the current version being standardized IMS Release IMS architecture is done with the aim of creating a platform to provide multimedia services which are capable of supporting rapid deployment types of services combining various media: voice, text, sound and image This control Structure IMS based on protocol SIP connection is capable of creating advantage conditions for third parties to easily deploy rich media services Structure control service is also the foundation for the convergence of fixed access systems and mobile Besides that the thesis also refers to the basic IMS architecture defined in 3GPP Release with the basic elements of the different kinds calls CSCF session control, home subscriber server HSS IMS-based architecture model includes subclasses: access layer are having many different forms of access, control layer with the central element calls CSCF session control, finally, the application layer which separated from the control layer allows IMS network operators to develop flexible, fast and new multimedia services Chapter II of the thesis researches into the IMS system architecture model of 3GPP standardization organization, made functional block diagram of the IMS network, a detailed analysis of functional elements in the IMS network as well as interworking communication between IMS network and other IMS peer network, the IMS network with circuit switched network technology such as public telephone network or GSM mobile phone network It also has analyzed the function of reference point of the interface pairing between IMS network elements Chapter III of this thesis, the authors applies the theoretical knowledge to analyze the IMS network, learn about IMS products of Alcatel-Lucent corporation, this firm is one of the suppliers of equipment and solutions to telecommunications, 104 Lun thc s Túm tt lun public informatic technology leading the world, Alcatel-Lucent was involved that contribute a lot in setting the standards of 3GPP IMS networks The IMS solution of Alcatel-Lucent is a flexible package with end to end products fully implement the function blocks of 3GPP IMS architecture Notable device is focus session control server 5060 ICS, this equipment is a key product in the stategy of Alcatel-Lucent in approaching to IMS network Finally, chapter IV of the thesis, the author verified the inspection evaluation of compatible device architecture between firm Alcatel-Lucent's IMS device and IMS control of IMS Nokia-Siemens, the protocol checking is based on test items that issued by the Post and Telecommunications corporation VNPT on IMS's standardization within his framework In collaboration with experts firm AlcatelLucent and Nokia-Siemens experts to establish the IMS connection model Test results showed that the access devices AGW of Alcatel-Lucent needs to adjust to the H248 protocol context so that one context implementation can allow more than connections, while the access equipment AGW od Nokia-Siemens company needs to modify the software protocol module to be able to execute the command MOVE received from MGC controller In addition to conducting testing protocol, it proves that SIP-I signaling by two firms meet well the test item requirements of VNPT 105 ...
