Abstract
A system and method for timely maintaining or establishing an R-P connection after a mobile station (MS) roams from the control of an old base station controller (BSC) to that of a new BSC is provided. The process may be initiated during a registration process of the MS, during an origination process, or during a termination process. A Mobile Service Center (MSC), Visitor's Location Register (VLR), or the MS may be used to store the packet data call status information including point to point protocol (PPP) session status information and configuration information about an old BSC including its related cells and PDSNs. In some cases, this information may also be transferred to the new BSC through a BSC to BSC connection.
