BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates generally to a mobile communication system, and more particularly, to a method and apparatus capable of performing call processing by interfacing a switch system with a commercial push server.

Voice over IP (VoIP) is a term used to refer to Internet Protocol (IP) telephony technology for a set of facilities that deliver voice information using IP. In general, VoIP means that voice information is transmitted in digital form in discontinuous packets, rather than a traditional circuit-based protocol like the public switched telephone network (PSTN), a public switched telephone network. The main advantage of VoIP and Internet telephony technology is that by integrating the telephony service using the existing IP network, the users of the telephone will be able to receive the local and international telephone service in the Internet and intranet environment with only the local telephone charge.

VoIP has evolved through VoIP forums to encourage the use of the International Telecommunication Standardization Sector (ITU-T) H.323, a standard for transmitting voice and video over IP over the public Internet or intra-company intranets. This VoIP Forum was attended by major equipment manufacturers. The VoIP Forum also encouraged directory service standards, enabling users to locate other users and enable the use of touch phone signals for automatic phone distribution and voicemail.

In addition to the original IP capabilities, VoIP uses Real Time Protocol (RTP) to support the arrival of packets in a timely manner. Using a public network for VoIP implementation is difficult to guarantee quality of service (QoS), but using a proprietary company or a private network managed by an Internet Telephony Service Provider (ITSP) Better service is possible.

Meanwhile, due to the development of an all-IP-oriented network, VoIP-based calls are supported not only in fixed-type terminals but also in portable terminals. More and more types of terminals are adopting VoIP technology. Typical examples of fixed terminals supporting VoIP include Internet telephones used at home, so-called "soft phones", desktop computers installed with installed applications supporting communication via VoIP, Computer. In addition, since the portable terminal supports a technology such as FMC (Fixed Mobile Convergence), it can support the communication service through the VoIP when accessing the IP network through the portable terminal.

The VoIP exchange system and the UC (Unified Communication) / FMC (Fixed Mobile Convergence) system including the VoIP exchange system include a signaling protocol such as a Transmission Control Protocol (UDP) / User Datagram Protocol (UDP) (FMC) clients, VoIP soft phones and IP phones based on wired networks using messaging protocols such as XMPP (Extensible Messaging and Presence Protocol).

On the other hand, in the mobile communication service system, the power consumption of the terminal, the CPU (Central Processing Unit), and the memory capacity are very limited. Therefore, conventional VoIP-based systems are commonly difficult to efficiently operate VoIP services in a mobile environment and a wired / wireless integrated environment. In particular, a keep-alive message for reporting whether the terminal is operating normally should be continuously transmitted / received to / from the system. Maintaining the registration status of the terminal always causes an increase in data usage and power consumption of the mobile terminal, There is a problem that it is limited.
