Method and apparatus for providing user identity based routing in a wireless communications environment

摘要

A method and apparatus for providing user orientated wireless data services over a wireless communications network to a plurality of mobile nodes. The wireless communications network includes a plurality of packet data servicing nodes (PDSN's), a plurality of packet control functions (PCFs), and a PCF-PDSN routing controller (PPRC). The PPRC acts as a single PDSN, as well as a surrogate PCF from the perspective of the PDSNs in the private IP network of the service provider. The PPRC serves to provide user oriented wireless services, as opposed to device orientated services. The method includes receiving a data session request from a mobile node, and initiating a point-to-point connection between a PCF receiving the data session request and a PPRC. The PPRC selects one of the PDSNs, and initiates a point-to-point connection between the PPRC and the selected PDSN. The PPRC splices a point-to-point connection between the receiving PCF and the selected PDSN, and commences a point-to-point data session between the mobile node and the PDSN, wherein IP packets are routed over a public IP network.
