Embodiment 1
[0059] This embodiment describes the relevant processing procedures when the TSCEF is located on the PCEF, Figure 5It is a flow chart of the PCEF executing the TSC policy and charging according to the embodiment of the present invention. Such as Figure 5 As shown, the process includes the following steps:
[0060] Step S501: the user equipment UE attaches to the network and initiates an attach process, or the UE initiates another packet data network (Packet Data Network, PDN for short) connection establishment process. The gateway where the PCEF is located receives the above request message.
[0061] Step S502: After the PCEF receives the attachment request or the PDN connection establishment request, it initiates an Internet Protocol-connection access network (Internet Protocol Connectivity Access Network, referred to as IP-CAN) session establishment request to the PCRF, and provides the PCRF with the user identification, PDN identification, IP address and other informat...
Embodiment 2
[0075] This embodiment describes the relevant processing procedures when the TSCEF is located on the TDF or TSSF, Figure 6 It is a flow chart of TDF or TSSF executing TSC policy and charging according to the embodiment of the present invention. In this embodiment, a charging-related interface is required between the TDF or TSSF and the OCS or OFCS. Such as Figure 6 As shown, the process includes the following steps:
[0076] Step S601: the user equipment UE attaches to the network and initiates an attach process, or the UE initiates another PDN connection establishment process. The gateway where the PCEF is located receives the above request message.
[0077] Step S602: After receiving the attach request or the PDN connection establishment request, the PCEF initiates an IP-CAN session establishment request to the PCRF, and provides the PCRF with user identification, PDN identification, IP address and other information.
[0078]Step S603: If there is no defined user subsc...
