    Internet Protocol Multimedia Subsystem (IMS) merupakan suatu arsitektur topologi framework untuk mengirimkan layanan Multimedia berbasiskan IP (Internet Protocol), yang telah menjadi arsitektur framework terkemuka yang sebagai enabler dari operator untuk menawarkan layanan VoIP dan layanan multimedia. Precopy Live Migration merupakan proses migrasi yang diterapkan pada IMS dengan cara page memory pada VM ditransmisikan pada fase iterasi ketika VM sedang dalam state running pada host sumber. Kemudian VM pada sumber di suspend menggunakan fase stop-and-copy dan sisa page memory ditransmisikan menuju host tujuan. Penelitian ini berfokus pada bagaimana IMS tetap dapat melayani pada saat terjadinya migrasi. Downtime yang terlalu lama akan berakibat pada pelayanan dari servis IMS tidak maksimal. Parameter yang akan diuji adalah Downtime, Waktu Migrasi, dan Jumlah data yang di transfer. Internet Protocol Multimedia Subsystem (IMS) is a framework architect topology to delivery multimedia services (Internet Protocol) based which has become the latest architect framework as operator services enabler that provide VoIP and Multimedia services. Precopy Live Migration implemented to IMS with VM’s memory pages are transmitted in the iteration phase, while the VM is still running at the source. After that, the VM is suspended in the stop- and-copy phase, and the remaining pages are transmitted to the destination. This research focused on how IMS can provide user during migration process. Longest downtime process will impact on service level to user. During migration process, Downtime, Migration Time, and Amount transferred data were evaluated. Keywords: downtime, migration, IMS, Virtual, precopy live migration

    This publication describes processes and techniques, implemented on a computing device, directed at enhancing videotelephony services during suboptimal network conditions. In an aspect, a several-stepped process employs a machine-learned technique through which captured frames (e.g., images captured by a videotelephony application) can be segmented and altered, such that an object of interest can be presented with a static background. The entirety of this process referred to herein as preprocessing logic, occurs prior to encoding

    Securing the IP Multimedia Subsystem with IPsec and HTTP Digest

    Modern Telecommunication networks were combined from two communications: cellular networks and the Internet. The Internet Protocol Multimedia Subsystem (IMS) is the key element in the Modern Telecommunication networks architecture that makes it possible to provide wide range cellular access to all the services that the Internet provides. So, IMS is a great achievement in the communication world with advantage to maintain single communication platform for all but the big challenge is to maintain an adequate security level in this different network environment. IMS is based principally on IP protocol. Therefore, it inherits the security issues of IP networks. The IMS architecture is open, distributed and it has the advantage of being flexible in its implementation and deployment. This generates a variety of communication interfaces, which can make the system very vulnerable to attack. Add to that, the services offered on the IMS network must be provided by ensuring confidentiality and respect the privacy of users. Therefore, it is necessary to secure the IMS network at every level of its architecture including the final customer or subscriber device. Solutions like firewalls, anti-spy ware and antivirus systems failed to counter the emerging threats because they only target specific types of threats. In this study we are proposing security approach which is a Combination model composed of two protocols IPsec and HTTP digest

    Simulation-based optimization of signaling procedures in IP multimedia subsystem

    This paper presents a simulation-based optimization of signaling procedures in Internet protocol Multimedia Subsystem (IMS). The aim is to improve the performance of signaling procedures by applying an algorithm for Session Initiation Protocol (SIP) message classification and prioritization that is proposed in our previous work. This three-priority level classification of SIP messages is implemented in Network Simulator version 2 (ns-2). Its effectiveness is verified through the simulation-based study of SIP signaling procedures under different conditions. The simulation results are analyzed in terms of Registration Request Delay (RRD), Session Request Delay (SRD), and Session Disconnect Delay (SDD). These SIP performance metrics are improved if IMS is configured to process SIP messages using the proposed algorithm. Differentiated handling of SIP messages reduces the overload in IMS and thereby improves the overall Quality of Service (QoS). This encourages our next step in research activity, i.e., implementation and incorporation of SIP message classification and prioritization algorithm into experimental environment

    Emergency-Only and Voice-Only Modes for Thermal Mitigation of Mobile Devices

    Get PDF
    A mobile device experiencing excessive temperatures can be placed in an emergency-only mode in which on-going calls are ended, new incoming calls are rejected, and new outgoing calls are ended by the device as thermal mitigation measures to prevent additional heat generation by the device. Optionally, when the device is being used in hands-free mode, a user is provided with the choice to override the emergency mode to make and receive calls. Alternatively, less restrictive thermal mitigation measures may be taken to prevent damage to the mobile device, such as restricting the device to certain voice-only services and restricting data services

    The paper is dedicated to mechanisms for open access to resource management in the Internet Protocol (IP) multimedia networks. First we present the concept of IP Multimedia Subsystem (IMS) and explain the IMS functional architecture, principles of quality of service management and service control in IMS. Then we describe the idea behind the opening of network interfaces for third parties so that others besides the network operator can create and deploy services. Open Service Access (OSA) and Parlay appear to be the technologies for value-added service delivery in multimedia networks. In the paper we take a closer look to the Parlay/OSA interfaces that allow third party applications to access the resource management functions in IMS. OSA "Connectivity Manager" interfaces and OSA "Policy Management" interfaces are considered. Parlay X Web Services interfaces provide a higher level of abstraction than Parlay/OSA interfaces and gain an amazing amount of support among service developers. We address "Applicationdriven Quality of Service" Parlay X Web Service and "Policy" Parlay X Web Service also

    BIOMETRIC AUTHENTICATION FOR PAYMENT TRANSACTIONS

    Get PDF
    The present disclosure relates to system and method of authenticating online payment transactions. The method includes receiving a payment transaction request from a mobile device 110. Upon receiving the payment transaction request, a digital payment system 120 transmits a request for user’s biometric data for performing biometric authentication. Upon receiving the user’s biometric data from the mobile device 110, the digital payment system 120 compares the received biometric data with the user’s biometric data stored in a memory. If the biometric data matches, the digital payment system 120 approves the transaction and a notification is sent to the mobile device. The proposed method may help visually impaired users to authenticate payment transactions using the biometric means. Further, the proposed method also helps to reduce fraudulent transactions
