System and method for packet data servicing node (PDSN)initial assignment and reselection |
摘要 |
An method for PDSN (Packet Data Serving Node) initial assignment and re-selection in a wireless communication system is provided. The method is implemented in PCF (Packet Control Function) within a third-generation (3G) CDMA Radio Access Network (RAN). The methodology reduces the number of point-to-point (PPP) re-establishments, when a Mobile Station (MS) roams to a different packet zone/PCF. The method generates a table of PDSN identification numbers cross-referenced to the PDSN Internet protocol (IP) addresses, residing with each PCF. A PDSN Id number is selected from the table using the MS IMSI (International Mobile Station Identifier) as a key to perform the selection. The present invention methodology addresses the issue of forward and backward compatibility, scalability, reliability, and load sharing in the PDSN selection.
