Method for virtual connection releasing in inter-operating network
The present invention provides a virtual connection releasing method in an inter-operation network. In the inter-operation network between the Enhanced Universal Terrestrial Radio Access Network (E-UTRAN) and the evolved HRPD (eHRPD) Access Network, a PMIP indication is set for indicating whether the HRPD Serving Gateway HSGW needs to initiate the Proxy Mobile IP (PMIP) binding updating operation or not. When the virtual connection releasing is initiated, the evolved Access Network (eAN) sends the A9-releasing-A8 message, which carries the PMIP indication, to the evolved Packet Control Function (ePCF). After obtaining the PMIP indication through the ePCF, the HRPD Serving Gateway determines whether to initiate the PMIP binding updating operation according to the PMIP indication. Application of the present invention enables the virtual connection releasing under the structure of the inter-operation between E-UTRAN and the eHRPD, and improves the virtual connection maintenance under the structure of the inter-operation between the E-UTRAN and the eHRPD.
