Method and apparatus providing context transfer for inter-PDSN handoffs in a wireless communication system |
摘要 |
In an exemplary embodiment of this invention contexts are transferred at an appropriate time depending on the context type. As a result, link layer (PPP) delay can be substantially eliminated during Mobile IP handoff, without introducing additional packet loss. By way of example, all MS contexts (both static and dynamic) are maintained during the inter-PDSN handoff procedure, and any executing applications are not impacted by the inter-PDSN handoff. |
