Embodiment Construction

[0019] Now turning to the attached image, figure 1 The internal structures of pPDSN in 3G-1x system and PCF and pPDSN in EVDO system are shown. like figure 1 As shown, the pPDSN in the 3G-1x system and the PCF and pPDSN in the EVDO system include: pPDP (dedicated packet data service node processor) 100, PDCC (packet data call control) module 110, PDTC (packet data service flow control) Module 120 and PDMA (Packet Data Maintenance Management) module 130 .

[0020] The PDCC module 110 manages the generation / termination of RP connection required for data transmission and reception, and handles the status of a packet call through the MN (Mobile Node) between the ATP and the DCN (Data Communication Network). PDTC module 120 is responsible for data transmission and reception between ATP and DCN. The PDMA module 130 is responsible for forming an interface with the O&M function module. In addition, the PDMA module 130 checks the status of the link connected to the ATP, the status ...

Abstract

A method for assigning an IP (Internet Protocol) address to an MN (Mobile Node) in a CDMA (Code Division Multiple Access) system, and more particularly to a method for assigning an IP address on the basis of a grade of an MN. In a method for assigning an IP address on the basis of a grade of an MN in a CDMA data communication system, the system including a database storing information of grades of MNs, a grade of the MN is identified from the database when an IP address assignment request associated with an arbitrary MN is received. Then, an IP address pool is selected from IP address pools of various grades on the basis of the grade of the MN, the IP address pools containing assignable IP addresses. Then, an IP address is selected from the IP address pool and the selected IP address is assigned to the MN.

Description

[0001] This application references, hereby incorporates and claims all interest arising under 35 U.S.C §119 from the patent application "Method of Assigning Internet Protocol to Terminals in a Code Division Multiple Access System," which was filed on September 11, 2002 To the Korean Intellectual Property Office, the official assigned serial number is 2002-55152. technical field [0002] The invention relates to a method for allocating Internet protocol (IP) addresses for mobile nodes (MN) in a Code Division Multiple Access (CDMA) system, especially a method for allocating IP addresses based on MN grades. Background technique [0003] In the CDMA (code division multiple access) 2000 EVDO (data-only evolution stage) system supporting 3G-1x InfoMobile service and private data service, such as the CDMA2000 packet data system used for private networks, in the form of functional modules in the system , Realize the PDSN (packet data service node) and data service equipment based on...
