PDSN-based session recovery from RBS/AN failure in a distributed architecture network |
摘要 |
An access node anchoring a connection to, e.g., a PDSN in a core network establishes a session with a mobile station and assigns the mobile station an identifier such as a UATI. The anchor node sends the UATI to the PDSN, such as in a GRE key where the data link is a GRE tunnel. If the anchor node fails and data addressed to the mobile station comes to the PDSN, it may initiate a page for the mobile using the UATI. The anchor node may additionally send the PDSN the session seed and optionally the mobile station's network location. A registration zone may be defined to include access nodes within a predetermined distance of the anchor node, and the mobile station forced to re-register when moving outside of the registration zone. In this case, the PDSN may initiate a page for the mobile station only within the registration zone. |
