Problems solved by technology

[0014] Refer to the above Figure 2 to Figure 4 It can be seen that after the emergence of the new PCC architecture, the PCEF function is divided into two parts, that is to say, there are two PCEF logical functional entities in the new PCC architecture, which leads to the establishment and deletion of IP-CAN sessions under the existing PCC architecture The method cannot continue to be used under the new PCC architecture, and currently there is no IP-CAN session establishment method and IP-CAN session deletion method under the new PCC architecture

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...

Abstract

The invention discloses an IP-CAN (internet protocol-connectivity access network) session establishment method. The method comprises the following steps: a PCEFa (policy and charging enforcement function) entity receives an IP-CAN session establishment request message; a mobile registration or a bearing establishment is carried out between the PCEFa entity and a PCEFb entity, a PCRF (policy and charging rules function) entity formulates a PCC (policy and charging control) regulation for the IP-CAN session and provides the IP-CAN session and the formulated PCC regulation to the PCEFa entity and the PCEFb entity; and the PCEFa entity returns the IP-CAN session establishment response message. The invention also provides an IP-CAN deletion method. By the adoption of The IP-CAN establishment method and deletion method provided by the invention, the purpose of establishing and deleting the IP-CAN session under a new PCC architecture can be achieved.

Description

technical field [0001] The present invention relates to mobile session technology, and more specifically, relates to an IP-CAN session establishment method and an IP-CAN session deletion method under the Policy and Charging Control (PCC) framework. Background technique [0002] In the third generation mobile communication standardization partnership project (3GPP) system, the policy and charging functions are implemented by the PCC framework. The PCC framework mainly implements two functions, one is the policy control function, and the other is the billing function. [0003] Among them, the policy control function mainly includes six aspects: first, monitor the negotiation process of the user's service parameters (such as QoS parameters); second, authorize the network bearer resources used by the service according to the obtained service information ; thirdly, control whether the service flow is passed or not in real time on the data bearing plane; fourth, notify the data b...
