RESIDENTIAL/ENTERPRISE NETWORK CONNECTION MANAGEMENT AND HANDOVER SCENARIOS

摘要

Residential/Enterprise network connection management and handover scenarios. A method, system and device are provided for managing LIPA and/or SIPTO connection releases when UE moves out of residential/enterprise network coverage in case service continuity is not supported for the LIPA/SIPTO PDN connection(s). To address problems caused by not providing service continuity for LIPA/SIPTO PDN connections, the PDN connection/PDP context created in the HeNB/HNB by the MME/SGSN includes context information related to the UE indicating whether such connection is a LIPA PDN connection PDN connection or not. In particular, when the MME (1708) receives a handover request (17-1) from a source base station (1704), if it determines that the active PDN connections are LIPA PDN connections and that LIPA PDN continuity cannot be supported towards the target cell, the MME (1708) rejects the handover and sends (17-2) a Failure message to the source base station (1704).
