Embodiment I
[0065] Figure 5 is a schematic flowchart of an IP-CAN session establishment method in an embodiment of the present invention, as Figure 5 As shown, the method for establishing an IP-CAN session in the embodiment of the present invention includes:
[0066] Step 11, the PCEFa entity receives the IP-CAN session establishment request message;
[0067] Step 12: Mobile registration or bearer establishment is performed between the PCEFa entity and the PCEFb entity. The policy and charging rule function PCRF entity formulates policies and charging control PCC rules for the IP-CAN session, and combines the IP-CAN session information with the established PCC rules are provided to PCEFa entities and PCEFb entities; and
[0068] Step 13, the PCEFa entity returns an IP-CAN session establishment response message.
[0069] Wherein, if the IP-CAN session adopts the online charging mode, the method in the embodiment of the present invention may also be as follows Figure 5 As shown, betw...
