One or more entities of a wireless communication network distribute address information for a source Packet Data Serving Node (PDSN) to the packet zones involved in reactivation paging of a dormant mobile station for network-initiated packet data delivery. A target Packet Control Function (PCF) supporting the packet zone in which the mobile station responded to the reactivation paging uses the address information to reactive packet data service to the mobile station through the source PDSN, if network connectivity permits. For example, the target PCF uses the source PDSN's IP address to send a registration request for the mobile station to the source PDSN. If the source PDSN is not directly reachable through the target PCF, the target PCF may send the source PDSN's P-P address to a target PDSN, and target PDSN can attempt to connect to the source PDSN for reactivation of the mobile station's packet data service.
