    • 3GPP Networking Evolution

    The 3rd Generation Partnership Project (3GPP) is a set of telecommunications standards used for cooperation. Currently, mobile communications comply with 3GPP standards.
    With the evolution of 3GPP standards, the networking for mobile communications and available services are changing.
    • Mobile communications network
      The mobile network has developed from the 2G global system for mobile communications (GSM) and the 2.5G general packet radio service (GPRS) to the 3G universal mobile telecommunications system (UMTS). Currently, mobile communications cover wide areas, boast high-speed wireless data transmission, and allow access to the Internet.
    • Available services
      Services such as voice, data, and video services are available, which meets users' requirements for communicating with others anywhere anytime.
    In the 3GPP protocol, no major modification is made to the packet switched (PS) domain, but the architecture of the bearer independent control network is introduced for the circuit switched (CS) domain in the 3GPP R4 version and the mobile switching center (MSC) in the 3GPP R99 version is planned as two network elements (NEs): MSC server and media gateway (MGW). In this case, bearer and control are separated.
