The present invention relates to a method and system for processing a higher UAL address for a multi-path in a wireless communication environment, and more particularly, to generate a multipath through an external menu link in a communication service provided in a wireless communication environment. The present invention relates to a method and a system for processing upper UL addresses for multipaths in a wireless communication environment for efficiently moving to a higher menu.

As computer, electronic, and communication technologies have made rapid progress, various wireless communication services using wireless networks have been provided. The most basic wireless communication service is a wireless voice call service that provides a voice call to a mobile terminal user wirelessly, which can provide a service regardless of time and place. In addition, while providing a text message service to complement the voice call service, a wireless Internet service has recently emerged to provide an Internet communication service to a user of a mobile communication terminal through a wireless communication network.

As a result of the development of mobile communication technology, a service provided by a code division multiple access (CDMA) mobile communication system transmits data such as circuit data and packet data as well as voice service. It is developing into a multimedia communication service.

In recent years, with the development of information and communication, IMT-2000 (International Mobile Telecommunication 2000), a third generation mobile communication system that has been standardized by ITU-R (for example, CDMA2000 1X, 3X, EV-DO, WCDMA (WideBand CDMA)) Etc.) are commercially available. Recently, the IS-95C network, which has evolved from the existing IS-95A and IS-95B networks, transmits up to 307.2 Kbps, which is much faster than the 14.4 Kbps or 56 Kbps data rate that can be supported in the IS-95A and IS-95B networks. It offers wireless internet at speed. In particular, by using IMT-2000 service, it is possible to provide various multimedia services (AOD, VOD, etc.) at higher speed as well as improving existing voice and WAP service quality.
